Как закрыть цоколь в свайно винтовом фундаменте: материалы для отделки, плюсы и минусы

Как и чем закрыть свайно-винтовой цоколь своими руками

Винтовые сваи являются продуктом новых технологий, разновидностью столбчатых фундаментов, которые незаменимы при строительстве на слабых грунтах. Данная технология дает возможность добраться до стабильных почвенных слоев без дополнительных затрат техники и материалов. Сваи считаются оптимальным вариантом фундамента для частного строительства. Надежные, безопасные, наиболее выгодные во всех отношениях опоры представляют простое и быстрое возведение фундамента. Изготовить его можно за несколько дней, в любую погоду, в любое время года, причем, несущие конструкции монтируются сразу же.

«Списочный состав» или варианты отделки цоколя

Одним из этапов завершения работ по строительству дома является маскировка непрезентабельных в эстетическом отношении свай фундамента. Неизбежно возникает вопрос, чем закрыть цоколь винтового фундамента? Специфика установки конструкции дома на сваи не предполагает обустройства цокольного этажа.

Однако возникают ситуации, при которых все же выполняются цокольные работы. Они отличаются от общепринятого понятия, предполагают: либо работы по рытью небольшой глубины ленточной канавы, связывающей сваи по периметру, либо отделку навесным цоколем. В свою очередь, навесная конструкция может быть представлена в разном исполнении.

Существует несколько способов декоративной отделки цоколя (так называется расстояние от земли до стен дома). Основные из них: цокольный сайдинг, отделка под кирпич, декоративные панели. Что примечательно, выполнить работы можно самостоятельно, не тратя деньги на оплату услуг специалистов. Традиционно внешняя декоративная облицовка выполняется сайдингом.

Навесная конструкция

Сделать навесную конструкцию несложно. Нужно только соблюдать очередность:

• Из металлических уголков, труб или деревянных досок создается обрешетка.

Заметьте. Важно не только, чем закрывать цоколь дома на сваях, но и то, в каком состоянии находится почва, какова глубина залегания подземных вод. Навесной цоколь располагается в непосредственной близости от земли, поэтому при угрозе подтопления территории он будет большую часть времени находиться в среде с повышенной влажностью. В этих условиях при сооружении обрешетки, каркаса под плитку, лучше отказаться от деревянных конструкций, облицовочных материалов на деревянной основе.

• Любым удобным способом (саморезами или сваркой) к сваям крепятся направляющие. Это может быт металлопрофиль, деревянные балки; своего рода каркас для фиксации на нем панелей или асбестоцементных плит, комбинированных систем с утеплителем или листового шифера.
• Перед установкой по периметру насыпается «подушка» из песка толщиной до полуметра.
• Удобным способом при помощи сопутствующих комплектующих формируются углы.
• Все швы затираются герметичным раствором.
• Дополняется оформление установкой отливов и других элементов, которых не хватает для законченного дизайна цоколя.
• Делу венец – финишная декоративная отделка.

Цокольный сайдинг: практично, быстро, эстетично

Если оформление должно выполнять только функцию декорирования без дополнительного утепления, то вполне подойдут панели сайдинга. Разнообразие фактур, цветов материала могут преобразить неоконченный открытый участок работ в аккуратный пьедестал, на котором возвышается постройка. Им может стать кирпичная кладка, кафельная или керамическая плитка, декоративный камень.

Сайдинг станет идеальным решением проблемы:

• Очень просто решить задачу типа: чем закрыть цоколь дома на сваях, используя это просто и понятный материал. Для самостоятельной работы понадобятся следующие инструменты и приспособления: шнур, метр строительный или рулетка, набор деревянных колышков, отвес, уровень строительный, доски, лопата, гидроизоляция рулонного типа.
• Пред началом работ площадка между сваями и около них освобождается от растительности, мусора.
• По внешнему периметру дома возле стен выбирается грунт. Формируется траншея глубиной до полуметра, шириной 0,3-0,4м. При этом ее внутренняя граница должна располагаться, чуть заходя под стены, а сама выемка земли производиться с образованием небольшого уклона в направлении от стен: на каждые 2 м по 1-5 см.
• Весь вырытый котлован, включая стенки, покрывается слоем рулонной гидроизоляции.
• На небольшой слой насыпанного щебня укладывается по периметру дренажная перфорированная поливинилхлоридная труба.
• В нескольких местах на поверхность выводятся дренажные колодцы – «скорая помощь» при заиливании системы для ее промывки.
• Трубы накрываются слоем 0,1 м мелкой щебенки. Траншея полностью по верхнюю границу засыпается песком, который хорошо утрамбовывают, выполняя уклон от стен.
• Формируется отмостка. Как вариант, это может быть тротуарная плитка, брусчатка или бетонная стяжка.
• На сваи привариваются держатели, на которые через отверстия будут крепиться направляющие.
• Выполняется каркас из деревянных (40х100 мм) или металлических элементов. Для предотвращения гниения дерева, оно предварительно обрабатывается антисептическим веществом.
• Используя J-профиль, наружные и внутренние углы с крепежами производится установка сайдинговых панелей. При этом выдерживается компенсационный промежуток 3-5 см на возможное расширение при изменении температуры между панелями и отмосткой.
• Сверху на готовую конструкцию устанавливается отлив, по которому осадки отводятся от цоколя.

Кстати, начать работы по обустройству цоколя никогда не поздно, даже предпочтительнее это сделать уже после того, как дом начинает жить своей жизнью. К нему уже подведены все коммуникационные разводки, поэтому есть время не спеша заняться отделкой.

Отдавая должное кирпичу

Если вы так и не решили, чем закрыть цоколь дома на винтовых сваях, а возиться с рытьем траншеи нет желания и времени, существует более простой способ оформления цоколя свайного фундамента – надежный, недорогой, быстровозводимый – кирпичная кладка. К сваям фундамента, покрытым защитной пленкой от поражения ржавчиной, по самому низу, приваривается металлический угловой профиль. Уголок с шириной полки 120 мм и длиной от 6м до 11,7м предварительно обрабатывается защитным антикоррозионным составом.

На нижний профиль, начиная с оформления углов, выкладывается облицовочный кирпич. Поднимаясь вверх по периметру, формируется кладка с ложковой перевязкой и выполнением швов не менее 0,05 см. Во избежание попадания вод сверху, на обложенном цоколе делаются отливы. Лучше если они будут декоративными, но можно использовать элементы из оцинкованной жести. Получается аккуратный, полноценный фундамент. Визуально и в стоимостном отношении он даже выигрывает у традиционного бетонного основания.

Экономичные пластиковые панели

Использую декоративные пластиковые панели вместо кирпича, получают экономическую выгоду, но проигрывают в эстетике: натуральный кирпич или камень смотрится богаче, красивее любой панели. Зато такая отделка отлично вуалирует свайное основание, выдерживает большие нагрузки благодаря увеличенной толщине панельного листа, неподверженности его химическому и биологическому воздействию.

При навесных панелях пространство под домом остается незаполненным, под ним не собирается влага, не образуется конденсат, благодаря хорошей естественной вентиляции. Панели точно повторяют рельеф участка, создавая внешнее абсолютное сходство с монументальным основанием, при этом сохраняя все преимущества, которыми обладает цоколь свайного фундамента, особенно на участках со значительными перепадами высот и другими сложностями рельефа.

Особенности отделки цоколя на сложных грунтах

Важно! Прежде, чем закрывать цоколь винтового фундамента на грунтах с глубоким промерзанием почвы, будь то навесные панели, камень декоративный, пр., нужно предусмотреть зазор размером 5-7 мм между грунтовым покрытием и декоративным оформлением.

Его необходимо выдерживать для обеспечения свободной вентиляции, а также затем, чтобы не повредить отделку при вспучивании почвы в морозную погоду. Образованную щель прикрывают сеткой, исключая проникновение под дом мусора, грызунов. Важно, чтобы проветривание осуществлялось в любое время года. Для предотвращения размораживания коммуникаций, их предварительно утепляют минеральной теплоизоляцией или монтажной пеной.

Эконом-вариант: бетонный цоколь и его отделка штукатуркой

Этот способ не только самый простой, но, пожалуй, самый экономичный. Не требующий больших финансовых затрат, значительных усилий для копки траншеи, установки направляющих. Просто делается отмостка. Отделывается цоколь водостойкими элементами (к примеру, асбестоцементными плитами). Внизу, у поверхности земли, зазор между отделочными панелями и грунтом присыпают песком. Однако именно штукатурка будет самой оптимальной отделкой в ситуации, когда финансовые возможности не позволяют приобрести более дорогостоящую обшивку.

Сейчас на строительном рынке появился ее новый, более дорогой вид, созданный на основе акриловых смол – мозаичная штукатурка. Это еще одно решение проблемы, чем закрывать цоколь дома на сваях. Штукатурка не только выглядит эффектно в разнообразии цветовой гаммы, но и наделяет цоколь высокими влагозащитными свойствами.

Сделав правильный выбор материала для отделки цоколя с учетом его эксплуатационных характеристик, местных климатических условий, соблюдая технологию работ, совсем не сложно собственноручно придать «продуваемому всеми ветрами» фасаду эстетичный, законченный вид.

Как закрыть цоколь в свайно-винтовом фундаменте

При строительстве зданий в обязательном порядке требуется монтирование основания. Речь идет о фундаменте. Однако, если ранее полезная площадь основания не всегда использовалась, то теперь собственники домов пытаются задействовать ее по максимуму. Варианты внешней отделки цоколя дома напрямую зависят от того, какой материал использовался для изготовления фундамента. Рассмотрим, чем может быть выполнена отделка цоколя современного свайно-винтового фундамента.

Цоколь можно закрыть разными способами

Варианты отделки

Среди большого количества облицовок можно отдельно выделить элементы, которые наилучшим образом подходят для каркасного основания. Рассмотрим более подробно наиболее распространенные методы обустройства этой части здания:

1. Сайдинг. Наиболее бюджетный и быстрый метод, при этом вся работа выполняется самостоятельно при помощи ПВХ панелей или дерева.
2. Кирпич. Наиболее дорогостоящий вариант, однако этот метод позволяет обустроить и использовать в полном объеме всю полезную площадь.
3. Пластиковые панели. Нередко, чтобы отделать фундамент своими руками, используют недорогие пластмассовые панели.
4. Отделка цоколя профнастилом. Еще один вариант наружной облицовки, который часто используют при обустройстве фундамента дома.

Встречаются также и иные варианты отделки навесного цоколя для свайного фундамента, однако они не так распространены, как описанные ранее варианты.

Важно. Чтобы качественно обустроить пространство подвального помещения, еще на этапе выбора материала требуется определиться с тем, для каких целей будет использоваться эта полезная площадь.

В данном видео вы подробнее узнаете как закрыть цоколь:

Сайдинг

Этот вариант отделки цоколя под современный свайный фундамент применяется достаточно часто, особенно при небольшом бюджете. Рассмотрим основные характерные черты этого варианта облицовочного материала:

1. Конструктивные элементы следует использовать, если необходимо выполнить сборную и недорогую конструкцию.
2. Обшить цоколь сайдингом допускается, если при этом не будет присутствовать большого пространства.
3. Использование сборных панелей позволяет только придать внешний вид, однако теплоизоляционных качеств добиться не удастся.
4. Обшивка сайдингом выполняется при сравнительно небольшом бюджете, а также необходимости быстро облагородить свободное пространство.
5. Сайдинг имеет сборную и достаточно плотную конструкцию, однако для облицовки всего периметра потребуются дополнительные элементы.

На практике облицовка из ОСП плит декорирования может также выполняться после основного заполнения стен основания более прочными материалами. Однако следует понимать, что сам сайдинг достаточно легко можно повредить механически, поэтому его применение не всегда рационально.

Важно. Если принято решение использовать именно этот строительный элемент для зашивки основания, то необходимо понимать, что сайдинг не рекомендуется углублять в грунт, так как он легко может повредиться.

Отделка из кирпича

Этот вариант зашивки основания позволяет сразу приступить к последующей эксплуатации полезной площади под фундаментом. Рассмотрим основные характерные черты для такого метода облицовки свайно-винтового основания:

1. Если необходимо надежно укрепить элементы над сваями, лучше всего использовать именно кирпич.
2. Этот материал отличает высокое качество и надежность, выполненное сооружение прослужит длительный срок.
3. Присутствуют хорошие показатели звуковой изоляции, а также термоизоляции внутри подвального помещения.
4. При таком исполнении изготовление отмостки свайного фундамента значительно проще соорудить.
5. Имеется возможность впоследствии использовать всю полезную площадь под домом, при этом нет необходимости сооружать капитальные стены.

Отличительная особенность кирпича — его сравнительно высокая стоимость, а также необходимость в последующей гидроизоляции, так как элемент плохо выдерживает длительный контакт с водой.

Важно. Если используется кирпич, то особое внимание уделяется технологическому процессу укладки, чтобы возведенное сооружение было надежным и углубленным в грунт.

Отделка из кирпича имеет ряд нюансов

Пластиковые панели

Еще один ответ на вопрос, как сделать цоколь на свайном фундаменте, – это выполнить облицовку из пластмассовых панелей. Рассмотрим этот вариант зашивки более детально:

1. Вариант с панелями сравнительно недорогой, что позволяет свободно их приобрести с небольшим запасом.
2. Изделия быстро монтируются, а также легко поддаются обработке в процессе подгонки под нужный размер.
3. Конструктивные элементы обладают сравнительно неплохой звукоизоляцией, однако не устойчивы к проникновению холодного воздуха.
4. Панели могут легко повредить при механическом воздействии, из-за чего их также не рекомендуется углублять в грунт.

Как и в случае с сайдингом, если выполняется основание, а также закрытие свайного фундамента пластиковыми панелями, чтобы впоследствии эксплуатировать всю площадь под домом, предварительно требуется качественная термоизоляция, а также защита сооружения от проникновения влаги.

Важно. Обустройство основания за счет пластиковых панелей выполняется достаточно быстро, так как в этом случае нет необходимости использовать дополнительные наружные строительные элементы.

Профнастил

Если нет необходимости каким-либо образом впоследствии использовать полезную площадь под зданием, то можно обшить фундамент при помощи металлических листов профнастила. Рассмотрим более детально основные характерные черты:

1. Эти изделия легко монтируются, а также подвергаются обработке при необходимости подгонки в размер.
2. Чтобы навесить все листы, предварительно может сооружают специальный каркас.
3. Материал сравнительно недорогой, однако стоит существенно больше сайдинга и пластиковых панелей.
4. Профнастил – это гофрированные металлические листы, выполненные из оцинковки.
5. Элементы не имеют хороших показателей звукоизоляции, а также защиты от влаги и холода.
6. Чтобы обустроить теплое основание, предварительно потребуется сооружать капитальные стены.

Дополнительно следует отметить, что гофрированный и оцинкованный металл устойчив к механическим повреждениям, а также воздействию влаги, из-за чего его можно спокойно заглублять в грунт.

Важно. Хотя этот строительный элемент имеет оцинкованную, а также крашеную поверхность, в местах креплений профнастила к каркасу имеются структурные повреждения, из-за чего их требуется обработать соответствующим образом, иначе материал рано или поздно подвергнется коррозии.

Как закрыть цоколь в доме при свайно-винтовом фундаменте (технология монтажа)

В зависимости от возведенного сооружения приходится решать, чем закрыть цоколь сооружения. Здесь требуется обратить внимание на целый ряд моментов:

1. Прежде всего требуется разобраться, для какой цели будет использоваться свободное пространство под основанием.
2. Необходимо иметь общие представления о финансовых вложениях, которые потребуются для обустройства.
3. Немаловажно учитывать особенности грунта, а также положение здания на территории участка.
4. Также следует учитывать наличие и изобилие грунтовых вод, которые присутствуют на территории участка.
5. В зависимости от выбранного варианта отделки может потребоваться использование или монтирование вспомогательных элементов.

Существует несколько технологий монтажа

Учитывая все эти моменты, следует заблаговременно определиться с используемыми материалами для обустройства цоколя в своем доме, который сооружен на свайно-винтовом фундаменте. Технологически монтаж включает в себя следующие процессы:

1. Грамотный подбор необходимых материалов для обустройства основания у сооружения.
2. Снятие точных размеров, а также последующее приобретение материала для проведения облицовочных работ.
3. После выполняется подготовка пространства для сооружения, а также приготовление инструмента.
4. После этого сооружается соответствующий каркас, к которому будет крепиться облицовочный материал.
5. Если используется кирпич, то под него обязательно укладывается на грунт основание, чтобы все основание не провалилось.
6. После сооружения каркаса выполняется облицовка всего периметра здания на свайно-винтовом фундаменте.
7. Впоследствии при необходимости проводится работа по обустройству наружной гидроизоляции и отмостки.

После этих мероприятий приступают к внутренней отделке сооружения.

Важно. В зависимости от используемого материала также подбираются вспомогательные конструктивные элементы (к примеру, для профнастила это металлический или деревянный каркас с выполненным усилением).

В настоящее время также встречаются и иные варианты облицовки цоколя на свайно-винтовом основании, однако не так часто. Следует понимать, что подобное устройство фундамента – это довольно сложная конструкция, которую должен выполнять специалист с использованием соответствующей техники. Также дело обстоит и с последующим обустройством. Если у владельца здания не имеется необходимого навыка и опыта, то рекомендуется доверить работу специалистам, чтобы не возникло трудностей и не было ошибок.

Responses about it are the most positive. 90003 90002 And the more difficult for the construction of landscape and soil conditions, the higher the efficiency of the use of pile technology. 90003 90002 Since its invention in тисяча вісімсот тридцять вісім, screw piles have been modernized many times, but have not been universally applied.90003 90002 However, approximately 80 years ago they acquired a practically modern configuration and became widely used first in the military and then in civil engineering. In our country, the demand for them began to grow rapidly after the crisis of 2008, and now the builders have no doubts about the advantages of screw pile foundations in comparison with conventional concrete structures. 90003 90002 The problem is that, because of the seeming simplicity of the process, only a completely lazy builder is not taking charge of erecting pile foundations and manufacturing welded piles today.Unfortunately, such an approach does not just discredit a good, but not so familiar for the Russian developer’s technology. Amateurish activities very often lead to truly devastating consequences. That’s why we decided to tell in detail about all the stages of the screw foundation installation, drawing the attention of potential developers to all possible “pitfalls”. 90003 90012 ADVANTAGES AND PLUSS OF THE PILOUS SCREW FUNDAMENT 90013 90014 90015 Lower cost and almost an order of magnitude shorter installation times compared to a concrete foundation.Н Carrying out works at any time of the year, as well as on marshy soils and reservoirs. 90016 90015 The possibility of completely abandoning earthworks or costly changes in the terrain of the site. And Work in dense housing and close to trees. 90016 90015 Readiness of screw piles to perceive the full design load immediately after screwing into the ground. 90016 90015 If necessary (for example, if the technician can not drive to the site) all work is done manually. 90016 90023 90012 GEOPROSIGHTS AND DESIGNING 90013 90002 Applying to the construction company with a request to build a foundation, the customer must prepare and transfer to the designers all the necessary information: address, description and purpose of the object, its number of storeys, wall material, building dimensions, etc.It is even better to provide an existing house project. But this builders will not be enough: in order to properly design the foundation, they will need information about the soils in the building site. 90003 90002 The fact is that the screw pile is a metal structure, immersed in the ground by screwing in combination with indentation. It consists of a tubular barrel (its diameter is 57,76,89,108 and 130 mm, the wall thickness is from 3 to 8 mm), one end of which has a pointed tip with a helical blade (can have a diameter of 150,250,300, 350 mm, and sometimes 500 and even 850 mm and the thickness from 4 to 10 mm), and on the second – the so-called shank with a hole for connecting the pile with the device used to twist it.90003 90002 Thanks to the helical blade, the pile is easily screwed into the ground, but does not loosen it. but thanks to a large step of “threading” cuts in a spiral. It easily passes the upper “loose” grounds, but when it reaches a dense layer located at depth, which exerts a high resistance, it begins to “brake” and almost stops. In this case, the pile stem is compressed from all sides by upper layers of the earth, which do not allow it to move horizontally, and the blade acquires the function of a support platform, which transfers the load to a dense layer of soil.90003 90002 That is why it is important for builders to know at what depth such layer lies, in order to calculate the necessary length of the pile. They go to a site where they not only study and measure the terrain, but also find out the geological features of the soils. 90003 90002 There are three ways to solve the problem. The first is a standard geo-prospecting, during which a trial drilling of one or several wells is carried out, a soil sample is sampled for study in the laboratory and subsequent issuance of recommendations.The cost of the service is from 30 thousand rubles. (Here the upper limit can exceed the lower limit many times). 90003 90002 The second method is test screwing of the pile. Usually a pile with a barrel diameter of 89 mm and a blade with a diameter of 250-300 mm is usually used, which is screwed into the ground until enough manual or mechanical force is available (which happens less often because it is unprofitable to send special equipment for trial drilling). If the length of the selected pile is not sufficient, the trunk is built up with a tubular coupling.90003 90002 If there is any doubt, another one or two piles are screwed. Plus such intelligence – its cost will be 6-10 thousand rubles. Minus – there is no guarantee that a dense layer under the pile has a sufficient depth and the structure will not fail in time. This drawback is deprived of the third way, which was developed by the company “SWF Group”. 90003 90002 Exploration is carried out using a special kit “Skif” (patent number 1338А7), consisting of two piles and a torque control device – UKKM-89.First, a pile with a diameter of 89 mm is screwed into the ground until the force of its twisting reaches a certain value as indicated by the instrument. 90003 90042 90002 See also: Foundation yourself 90003 90042 90002 The first pile is removed, and in its place is screwed a thinner one – with a diameter of 57 mm. It enters the ground to a much greater depth, which allows you to more accurately judge the thickness of the carrier layer. Drilling is carried out in at least two points of development and costs 3,5-6 thousand rubles.90003 90002 Based on the results of geo-prospecting, a preliminary design of the pile foundation is carried out, in accordance with which the technical and design documentation required for the conclusion of the construction contract is developed, the cost of the works, etc., is determined. 90003 90050 90002 90052 On the basis of engineering calculations, in which the loads created by the house and its design features are correlated with the bearing capacity and location of the piles, as well as the geological prospecting data for the site, an individual pile-field design is developed that indicates the location of each screw support, its brand and dimensions (length, diameter trunk and blades, etc.) 90053 90003 90055 90012 MANUFACTURE OF SCREW PILES 90013 90002 On an industrial scale, screw piles are produced in two ways. The first of these we will conditionally call welding. First, at one end of the tube, special shaped petals are cut, then they are rolled and welded together, creating a sharp tip to which a metal blade is welded. 90003 90002 In the second method, conventionally referred to as injection molding, the steel tip of the pile together with the blades is made by casting and welded to the pipe.90003 90002 Products with a cast tip are superior in strength and reliability of piles with welded (they have only one seam), but they are heavier and cost about 20% more expensive. 90003 90002 Screw piles with welded ends are mainly used in low-rise construction. And today’s market, unfortunately, in huge quantities offers such handicraft products with substandard welds. But the weight of the building on the ground is transmitted through the blades, which means that, as far as the quality of the blade is welded to the trunk, not only does the bearing capacity of the pile depend, but also the reliability of the foundation construction.90003 90002 For the pile to live as long as possible, a protective coating is applied to its surface. Crafts-loners offer a variety of options – from the primer to the bituminous mastic. But serious A manufacturers paint piles with compositions on an epoxy basis, create composite coatings, conduct powder coating and even hot-dip galvanizing (both outside and inside). 90003 90002 Of course, such a coating is much more expensive, but it will not be removed from the pile even when screwing and will protect it from corrosion for many years.That’s why experts advise buying products exclusively from large and well-known manufacturers that are able not only to color the piles qualitatively, but also to control the quality of all welded joints without exception in their own laboratory. 90003 90012 CRITERIAS OF CHOICE 90013 90002 The number of piles, their diameter, length and wall thickness of the pipe and blade are determined on the basis of the condition of maximum strength of their construction and base soils with an allowable design load.The listed sizes can be very different, and for each object they are selected individually, taking into account the values ​​and directions of the loads, due, inter alia, to the technology of erecting the building (wooden, brick, etc.) . Ready-made recipes for all cases are not and can not be. But in order to orient the reader into the sea of ​​products, we publish a table, which is only a short extract from the rules for the use and installation of piles SP 50-102-2003 (the length of the products for each case is individual and therefore not shown in the table).90003 90002 It should be added that the foundations are designed in the form of single piles (stand-alone pylons), tapes (under the walls of buildings) or bushes (for example, under columns – while piles are twisted into the ground from one point , but in different directions and at different angles) or a continuous field (under heavy pile structures can be combined with a monolithic slab). 90003 90042 90002 See also: Building the right foundation – calculations of walls and floors 90003 90042 90012 QUALITY CONTROL 90013 90002 After completion of the design process, the piles are manufactured and brought to the building site.At this stage of the work, the customer has the right to check their quality. First, see if there is a lot of rust on the inner surface of the pipe, measure the thickness of its wall – it should be the same along the entire circumference. If the rust on the inner surface of the pipe is a thick layer, and the uneven thickness of its wall exceeds 0,5 mm, then most likely the piles are made from a used pipe. They will not live long. 90003 90002 Secondly, for welded products measure the thickness of the blades and visually evaluate how well they are welded to the pile stem.If the blade is thinner than 4 mm or the weld seam is discontinuous, discard such piles. 90003 90002 Third, try to scratch the pile with a metal object. If you immediately scratched the coating to the metal, it means it is weak and will be torn almost completely during the screwing process. 90003 90012 FOUNDATION FOR WINE PILES – INSTALLATION 90013 90002 The installation of screw piles is manual and mechanized – the choice of method depends not only on the size of the products, but also on a number of other parameters, including economic ones.90003 90002 The manual method is usually used in those cases when it is more cost-effective or difficult to enter the machinery to the site. Before screwing the piles with a blade diameter from 250 mm, as a rule, a pit is drilled or drilled with a depth of no more than 0, D m, which greatly facilitates the work. To twist, simple tools are used: a long tube-lever, which is inserted into the aperture of the shank, or a steel rod (sometimes scrap), which is placed in the same hole, and then long enough lengths of pipes are put on it from both sides.When screwing the workers have to carefully (for example, using the building level) to ensure that the pile entered the ground strictly vertically. 90003 90002 For machine “drilling,” specialized installations with a retractable boom are used, mounted on trucks or tractors. In this way, it is possible to twist the piles length, limited except that the outset of the boom of the installation. Perhaps the only difficulty in doing this is to get to the top of the long pile to insert the pin into the hole of its shank and connect it to the rotating arrowhead.90003 90002 The speed of creating the pile field by a mechanized method is naturally higher than manual: for example, the machine can spin 20 piles with an 2,5 m length in 2 h, whereas a team of experienced installers will manually handle this task in one working day. However, the high cost of renting equipment often makes it necessary to abandon its use in the construction of foundations for small houses. 90003 90002 The customer also has the right to take part in the acceptance of the ready pile field.In this case, you can and should be guided by the following criteria: 90003 90100 90015 deviations of the position of piles from the plan should not exceed ± 0,2 mm from the diameter of its trunk; deviation of the axis of the pile vertically – no more than ± 2% of its length; 90016 90015 horizontal deviations ± 10 mm in structures with grillage and ± 50 mm in structures without it (piles are provided with only a headband). 90016 90105 90012 CUTTING THE PILE 90013 90002 In advertising of some firms it is possible to meet the phrase “Exact vertical screwing of piles according to the level”, which according to the plan of its negligent authors is intended to demonstrate the skill of the brigade working on the site.Experts advise: when you see a similar wording, contact another company. And if on your site the piles are twisted into one level – sound the alarm and stop the work: some elements of the construction did not reach the solid layer and can subsequently fail. The fact is that the layer of hard ground in which the piles of the pile must “get bogged down” is not perfectly even. Consequently, the blades of the piles that reached it also can not be at the same depth. Hence, the ends of the tailings of properly twisted piles will be located at different heights and they will have to be cut to the same level.90003 90002 However, similar work will have to be done for another reason as well – the pile shank has a through hole with a diameter of 35-50 mm. It not only significantly weakens the structure, but its edges are often twisted when screwing (and the shank is twisted). In addition, through the hole inside the pile, even through the concrete poured into it, moisture can penetrate, which provokes corrosion. Therefore, if the workers refused to cut the shanks in the level below the hole, also stop the work and take appropriate measures.90003 90012 FILLING BY CONCRETE 90013 90002 After the screw piles are cut, their trunks are filled with concrete. This operation is necessary in order to prevent the ingress of water and air into them, and, therefore, to prevent the formation of corrosion and to extend the life of each individual pile and foundation as a whole. For pouring usually use sand concrete of the brand not lower than M300, diluted with water to the state of liquid slurry – otherwise it will not reach the tip of the pile.It is possible to compact the concrete inside the trunk with a long reinforcing bar. 90003 90012 MOLECULAR DEVICE 90013 90002 Grillage is a structural element that serves to evenly distribute the loads created by the frame of the building to the foundation piles. The choice of its type is due to the type and design features of the structure. In most cases, so-called hanging grilles are used, which we conditionally divide into wooden, metal and concrete. 90003 90002 Wooden version is used for houses built from logs and beams, including glued ones.To create it, a special headband with a platform is welded to the top of each pile, and the functions of the grillage are performed by the first crown of the structure, which is fastened to threaded pins with threaded studs with nuts, wood screws, etc. A layer of waterproofing (ruberoid, bikrost, etc.). 90003 90002 When a metal grill is used, the vertices of the rows of screw piles are connected by a channel or I-beam. The assortment of the beams of the grillage is determined depending on the operating loads.The main regularity when choosing: the wider the distance between the piles (step), the larger the cross-section of the beam should be. All elements are connected together by welding or bolting. 90003 90002 The channel in such constructions can be laid on an edge or flat. When installed on an edge, it works better for deflection. To enhance this effect, the channels are often installed in pairs – wide or narrow shelves to each other (in the first case, the construction resembles an I-beam, in the second – a box).90003 90002 When laying flat, the channel is fixed to welding directly to the pile, which makes it possible to do without headers and lower the cost of the foundation. I-beam beams for strapping are mainly used in the reconstruction of the foundation. 90003 90002 Reinforced concrete grillage is used in the construction of light wooden houses in areas with uneven terrain or in the construction of heavy buildings of brick or blocks. In the first case, a gap is left between the structural element and the soil, in the second there is no need for a gap, and the grillage turns into a shallow-recessed tape transferring the load to both the piles and the ground between them .90003 90002 In any case, the grillage is arranged as follows. In the trunk of the pile, before the end of the pouring of concrete, reinforcing bars are inserted, which later bend laterally. Along the piles, a formwork is installed, where an appropriate power frame is created, connected with the “anchored” reinforcement in the support, and then concrete is poured. 90003 90012 Pile screw foundation – important points 90013 90134 Save the trees 90135 90002 For the construction of a pile-and-screw foundation in the conditions of existing construction, it is possible to use compact equipment installed on a small car.When moving such equipment around the site or during the twisting with its help, screw piles are practically not damaged by grass, flowers, or trees located near the work site. So, summer residents may not worry that their favorite garden will die during the construction of a new house in place of the old one. 90003 90042 90002 See also: Holiday home with your hands, from the foundation to the roof 90003 90042 90134 NODES OF STRENGTHENING THE FOUNDATION 90135 90002 If the house plans to install a heavy furnace (for example, brick) or a fireplace (say, so-called soapstone, which keeps heat well), this should be warned in advance by the designers.90003 90002 They will provide special reinforcement nodes in the structure of the foundation, which include additional piles connected by a griller. Often, the latter will be more powerful than the foundation piles (as a rule, the minimum diameter of their trunk is 130 mm). It is difficult to create such an amplification node after the construction is started, and after its completion it is impossible. 90003 90002 90003 90002 The pile-foundation foundation is one of the most quickly constructed.For example, to create a field from 24 piles (a) 4 h is machine-generated by machine, and after 4 h all of them are cropped and equipped with headers (6). Manual screwing (in) takes twice as much time. 90003 90002 Unlike manual installation, the machine does not require preliminary excavation. But to monitor the vertical position of the support must be more careful than with manual screwing – the machine operator of the installation can not feel the deviation of the pile as clearly as the workers 90003 90134 INSTALLATION OF THE PILE SCREW FOUNDATION IN WINTER TIME 90135 90002 The pile-screw foundation can be successfully mounted even in winter.First, with the help of a powerful drill, the upper frozen layer of soil is opened. Then the drill is disengaged from the boom, a pile is attached to it and quickly, before the ground has not had time to freeze, screw into the drilled “hole”. Manual drilling in winter is also possible – the frozen ground is opened using a jackhammer or a powerful perforator, and then the pile is screwed in. The only existing restriction: it is not necessary to fill the piles of concrete piles with frost more than -15 ° C.90003 90002 90159 Screw foundation on an uneven site – it’s the most! 90160 90003 90002 In periods of protracted precipitation, even heavy reinforced concrete bases can be “washed off” from the slope on which they are located. The technology of erecting foundations on screw piles is best suited for such areas, since it allows the use of piles of different lengths in one design. In addition grillage, for their strength, they are additionally connected with braces from a corner or a square pipe.To the braces and piles, you can immediately weld a skirt, to which the base will be fixed. 90003 90134 Strength of pile screw foundation 90135 90002 The problem of erecting any buildings on the water from ancient times was solved by means of the pile foundation. The quay or pier is usually constructed in winter, when the pile-driving technique is capable of standing on ice. With the help of screw piles, work is carried out almost all the year round, because the equipment for screwing the piles can be located on a temporary floor (for example, from thick steel sheets) laid on the newly created part of the pile structure , while testing it for strength.90003 90134 Outbuildings and terraces 90135 90002 The base of an outbuilding or terrace, as, indeed, any pile foundation, is mounted very easily. However, one should take into account that it will not be able to be brought close to the base of the existing building – the minimum distance from the edge of the old foundation to the center of the nearest new pile will be approximately equal to the radius of the blade of the screwed pile. Since the soles of both foundations will be on different elevations, the walls of the existing building and the ends of the extension walls will have to be connected so that they can move relative to each other.90003 90002 90173 At what level should the piles be cut? 90174 90003 90002 First find the pile, which is deepest in the ground, and make a mark on it just below the hole in the shank. Then, using a theodolite, water or laser level, labels at the same height are placed on all other piles. 90003 90002 Piles are cut in accordance with the marks, using a Bulgarian or autogen. Basically, they use a Bulgarian, and autogen is needed only in cases where the tail of the pile is placed in a concrete grillage or the wall of the pile shaft is thicker than 6 mm.90003 90134 RECONSTRUCTION OF THE FOUNDATION 90135 90002 During the reconstruction, first of all, a technical examination of the foundation and the whole building is carried out, as well as trial drilling, which results in the development of a technical design. Further, the selected piles are immersed in the ground to the design mark from two opposite sides of the existing foundation. After that, in the wooden house, dismantle the basement and screw into the ground the necessary number of piles inside the building.Then the building is lifted with the help of jacks, we bring under it girder beams (most often use I-beams) and attach to piles. On the metal lay a layer of waterproofing and only then set the house in place. 90003 90134 LIGHT CONSTRUCTIONS 90135 90002 Screw piles are now widely used in the construction of lightweight structures, such as carports, covered terraces, arbors, etc. Their metal stands, usually already equipped with flanges with holes, are attached to round pile heads with bolts. If the structure has wooden racks, then they are fixed in special “glasses” attached to the heads.When constructing a light metal structure in place, you can choose a different path – to order piles more authentic and use their shanks as racks. 90003 90012 Finishing the base of the pile screw foundation 90013 90002 The simplest version of the device and finish of the cap is as follows. First, a frame is constructed of steel profiles that are attached to piles by welding or with screws, and then DSP slabs or glass-magnetite sheets are attached to it. The plinth can be painted in any color, plastered and then painted, adorned with decorative stone or socle siding.90003 90002 A more powerful and therefore reliable version of the socle can be done in the following way: either by welding or screws fasten to the piles at the ground level a laid flat channel with a wall not less than 125 mm in height, or cast out of concrete B7.5 class along the piles outside (sand preparation) tape of the same width as the channel, and then on top of them lay the socle of necessary height from the red solid brick. 90003 90002 Then they perform a blind from the monolithic concrete of the same class, and the gap between the wall of the house and the brick cap is covered with an ebb.The method of finishing the structure depends on the preferences and financial capabilities of the owners. It is plastered and painted or covered with decorative textured plaster, as well as a plinth of DSP boards, facing with siding, plastic panels with a pattern for stone, etc. Experts do not recommend using heavy natural stone – the structure can begin to break away from the wall under its own weight. 90003 90002 90003 90002 The piping is made using an I-beam (a), a channel (6), wood (c) or reinforced concrete (g).In any case, grillage allows more evenly distribute the load created by the structure between piles 90003 90002 When constructing a wooden grillage (a), the fastening can be pre-welded to the pile heads (6).

A headband is attached to the shank, and to it – a grillage of one type or another, depending on the features of the erected structure (bar, metal channel, reinforced concrete beam or slab, etc.). In private housing construction, piles made of St3 steel (carbon, ordinary quality), with a barrel diameter of 108 mm and a blade diameter of 300 mm, are commonly used. 90003 90006 90002 90008 The use of piles makes it possible to accelerate the process of constructing the foundation (it takes 1-3 days), and in the case of a small building, it is also possible to save on its foundation 90009 90003 90011 90002 90013 The foundations on screw piles have many advantages. 90014 90003 90002 They are universal – suitable for all buildings, including for small architectural forms (fences, piers, etc.). They allow building a building on problemy grounds – loams and clay (subject to a strong frost whipping), products often produce them from rejected or already used pipes (and they, with rare exceptions, do not have the required quality). In addition, these piles are installed without preliminary soil testing and with a violation of the installation technology. Obviously, the life of such grounds remains questionable. So the first task facing the customer is to select quality piles. How to do it? 90003 90002 First of all, it must be remembered that exhibition samples in the offices of manufacturers may differ from the products delivered to the facility (for example, “exhibition” piles can be cleaned, sealed and painted poorly welded seams to make the product look more attractive).90003 90006 90002 90008 “If you order soil testing with screw piles, check that the brigade has two piles of different diameters, a torque control device, levers and a level for checking the height difference. With the help of a pile of a larger diameter determine the depth of the bearing layer of the soil. Piles of smaller diameter are screwed into the same hole in order to obtain information on the layers of soil at depth, to reveal the presence of voids and quicksides under the pile blade.When building pile-screw foundations manually, there are many cases when piles are screwed in insufficiently, evaluating the performance of works “by eye”. Therefore, it can be recommended to the customer to monitor, that when screwing the piles, the brigade would monitor the torque using a special device. If the installation is performed using a mechanized installation, the team must necessarily have an adapter between the rotator and the pile (so that it is not pressed into the ground, but simply screwed).90009 90003 90011 90002 Therefore, it makes sense to ask to demonstrate samples of “real” piles, and then evaluate all products delivered to the site. The pile should have a smooth trunk with a high quality weld (if an electrically welded pipe was used for its production). 90003 90002 The pile should have a wall of the manufacturer’s declared thickness (usually not less than 4 mm), moreover this thickness should be the same along the entire length of the product (often in cheap piles the wall thickness is reduced – along the entire length or in some sections of the trunk).It is necessary that the helical blade is located perpendicular to the trunk and has the correct shape (and then the pile will not loosen the ground during installation, but, on the contrary, compact it and gain torque). 90003 90030 90002 See also: Foundation on screw piles 90003 90030 90002 One of the important differences between products from serious and “garage” manufacturers is the quality of the welded seam at the place where the blade is connected to the trunk (in pavilion construction, piles are most often used with the welded way of fixing the blade).Pay attention: the blade has the main load from the building. 90003 90006 90002 90008 Is it true that screw piles are a cheap foundation? 90009 90003 90002 90008 Screw piles were not designed to make construction of a building cheaper, but in order to create a reliable, but at the same time, budgetary foundation in conditions of difficult soils (unstable, puchinistyh, with a high level of groundwater, etc. ). However, today the market can meet proposals that attract very low cost of piles and works on their installation.For example, the foundation size 6 x 6 m, along with the installation can cost about 30 000 rub. However, for such a small amount of money you will be offered either piles of questionable quality with the installation of seasonal brigades. Either piles with acceptable consumer properties, but designed for small light structures that are designed for a short life. If the customer needs a durable building built on a complex ground, he will have to order an engineering and geological survey of the soil, acquire high-quality piles with a full anti-corrosion coating, and entrust the installation to a qualified team.In this case, the foundation on screw piles may not be the most economical solution, often comparable in cost to the device of a small-groove ribbon foundation (which, however, does not have high reliability in undergrowth conditions). 90009 90003 90011 90002 Accordingly, the bearing capacity of the pile depends directly on the quality of the welding, as well as the possibility, without deforming the blade, to screw the pile into the ground. The seam should be two-sided (on both sides of the blade), smooth, without unprocessed patches, cracks.The width of the seam should be about twice as large as the thickness of the blade. Meanwhile, many parameters that characterize the quality of the pile are not visible. Thus, in handicraft production, cheap welding machines are used, which often allow the metal to be recoated during welding, which leads to a weakening of its structure and provokes acceleration of corrosion in the weld zone. Therefore, it makes sense to purchase piles from large manufacturers that have modern equipment and are able to check the quality of products (including welded joints) in the factory using special devices (ultrasonic, X-ray inspection, etc.). 90003 90006 90002 90008 Studying the contract with the company that will perform the work on the installation of piles, find out what the warranty covers. Many firms go for a trick: they give a guarantee on piles, and not on the foundation. Although the customer buys not piles, namely the foundation 90009 90003 90011 90002 Concerns of customers cause also that in due course the metal pile will be destroyed under the influence of corrosion. However, it is worth bearing in mind: the main part of the pile is in the ground, where there is little oxygen necessary for the development of corrosion.90003 90002 So this process will proceed much more slowly than it happens when the metal product is located in the open air. Note that the life of a particular pile will depend on many factors, including the chemical composition of the soil, the degree of its saturation with moisture, etc. To increase the life of the pile, a number of measures are taken. First of all, an anti-corrosion coating is applied to it in the factory. However, these coatings are different, and, consequently, their effectiveness is not the same.Often the pile is painted with rust paint: it is cheap enough, but has low wear resistance. 90003 90002 More expensive, but also more effective solution – to paint with enamel on an epoxy basis. It is able to provide long-term protection against corrosion: according to the manufacturers, the pile with such a coating, if found in the most aggressive soil conditions, will last at least 50 years. At the same time, the enamel has a relatively low strength and can be torn off during the installation of the pile (in particular, large stones).Even more expensive, but at the same time more effective – powder painting. 90003 90002 In comparison with enamel powder paint creates a more durable and wear-resistant coating on the surface of the product. Finally, the most serious obstacle to rust is hot-dip galvanizing. True, galvanized piles are very expensive, and they are used very rarely in private house-building. Note that the part of the pile that is in the upper layer of the soil (where the oxygen content is higher) is more susceptible to corrosion.90003 90002 Therefore, a number of specialists recommend additionally to protect the trunk at this point with a polymer shrink tape. In the process of installing the piles, the tape is welded onto the barrel, so that it covers the pile by about 40-60 cm under the ground and at the same height above the ground. Another standard measure to protect against corrosion – the filling of the barrel already installed piles of concrete grade M300. which will not allow the ingress of water and air into it.Pay attention: if the piles are not concreted from the inside, this is a gross violation of the installation technology. 90003 90030 90002 See also: Foundation yourself: from the barn to the house 90003 90030 90068 Errors in the installation of pile-screw foundation 90069 90002 The problem that homeowners may face is an uneven foundation of the foundation on the screw piles, fraught with distortions and deformation of the building. In many cases, this is the result of an unjustified saving of the customer or installation organization that refused to perform a preliminary soil survey and just screwed the piles to a depth below the freezing zone of the soil (its value depends on the region where the construction is being carried out).However, information on the depth of freezing is not enough. 90003 90002 Only a special study of the soil can determine the depth at which the hard soil is located, as well as the thickness of its layer. These data make it possible to accurately determine the length, type, diameter, quantity and layout of the screw piles that will be needed to construct the foundation on a particular site. 90003 90002 The most complete information about the ground can be obtained with the help of geo-prospecting, carried out by specialized organizations (excavation of soil with sufficient depth by non-destructive method, analysis of samples taken in laboratory conditions).But, firstly, the cost of such research is quite high, and secondly, the resulting data are useful to a greater extent for the designers (that is, it is relevant when the building is built with the involvement of the project organization). Therefore, most often choose an inexpensive, but quite effective method – trial screwing of the pile. It is carried out by the firm that is installing the foundation. 90003 90006 90002 90008 When building a foundation on screw piles, it is necessary to carry out geological engineering survey of the soil.Without it, you can not accurately determine the depth of the piles, at which they will have the required bearing capacity. The professional skills of the brigade carrying out the construction of the foundation are also important. In particular, unqualified executors are often unable to ensure the verticality of the pile: permissible deviations of its axis along the vertical should be ± 2% of the length of the trunk (according to JV 50-102-2003 “Design and construction of pile foundations “). Errors during installation negatively affect the reliability of the foundation.90009 90003 90011 90002 In this case, the pile is screwed until its blades are in a layer of soil with the required bearing capacity. 90003 90002 Most often do several trial screwings in different parts of the building spot (their number depends on the size of the erected building, usually 2-3). 90003 90002 The main disadvantage of this method: it does not give information about the thickness of the hard layer of the soil. In addition, the load-bearing capacity of the soil is usually determined manually – by the amount of torque required to screw the pile, which can introduce a serious error in the results of the study.90003 90002 These disadvantages are devoid of technology, the feature of which is that it involves screwing into one hole two piles – at first larger, and then smaller diameter (to determine the depth of the carrier layer). In this case, the torque is measured using a special tool. 90003 90002 The reliability of the foundation can be questioned and unqualified installation. I must say that the piles can be screwed either manually (using a lever inserted into the hole in the tail of the pile), or with a mechanical installation with a retractable boom.For a private builder, the manual method is cheaper (besides, it is non-alternative if a mechanical installation can not be delivered to the site). However, it requires great responsibility from installers. 90003 90002 Meanwhile, often low-skilled teams facilitate their work, for example, due to the fact that before diving piles dig too deep pits (more than 20 cm), necessary for the adhesion of the blade to the ground. In this case, the upper part of the soil loosens, which causes the pile’s bearing capacity to deteriorate and its stability to decrease.Customers should pay attention to how the team checks how well the pile is twisted. If only by the effort that workers make to rotate the pile, there is a danger that it will not be screwed to the required depth. 90003 90002 According to some experts, only brigades that have in their arsenal a dynamometric key or a special tool for measuring torque, can accurately determine when to stop twisting the pile. Other experts say that it is possible to provide quality screwing without a measuring tool: it is enough to wrap the pile up to failure, as evidenced by the deformation of the shank.90003 90002 In this case, the torque exceeds the required torque and, consequently, gives the required result. Let’s note, at mechanized screwing of piles the probability to receive a reliable foundation is higher. And of course, the customer should check the quality of the work done, guided by the joint venture 50-102-2003 “Design and construction of pile foundations.” In particular, to assess the smoothness of the pile installation (level, hydrostatic level) and the accuracy of the pile field (measure the distance between the piles).90003 90030 90002 See also: The correct foundation under the house – the ratio of the weight of walls and floors 90003 90030 90002 A few words about grillage. 90003 90002 There is an opinion that in the case of wooden or frame houses it is best to tie the piles with a metal channel. Many experts disagree with this: the channel, laid flat, does not work well at the deflection. It is better able to withstand the load when installed on the edge, but its shelf is too narrow to erect a wall over it.In this connection, it is recommended to perform a grillage, for example, from a beam with a cross section of at least 200 x 200 mm, a profile pipe, an I-beam, etc. 90003 90106 Construction of pile-screw base: photo 90069 90002 90003 90110 90111 a, b) The foundation was built using a mechanized installation, c) Installed piles 2,5 m long with a barrel diameter of 108 mm and blades – 300 mm. d) The water level was used for the marking, e) The pile field e) The shanks were cut by the Bulgarian g) The tops of the piles were tied together by a metal channel, s, i) The walls of the frame building were installed over the channel, k) The plinth was finished with an artificial stone 90112 90003 90114 90115 TOOLS FOR MASTERS AND MASTERS, AND HOME GOODS ARE VERY CHEAP.FREE SHIPPING.
