Description

Изобретение относитс ,к строительству , а именно к способам возведени фундаментов столбчатого типа.The invention relates to the construction, in particular to methods for the construction of columnar type foundations.

Известен способ возведени фундамента столбчатого типа, включающий монтаж опорной плиты, установку опалубки подколонника, установку его арматуры и укладку бетона в опашубку 1.There is a known method of erecting a columnar type foundation, which includes the installation of a base plate, the installation of undermill formwork, the installation of its reinforcement and the laying of concrete in the jacket 1.

Наиболее близким к предлагаемому вл етс способ возведени столЬчато-го фундамента, включающий выполнение опорной плиты, монтаж арматуры подколонника и наружной опалубки и укладку бетона 2.Closest to the present invention is a method of erecting a wooden foundation, which includes the construction of a base plate, the installation of under-column and external formwork reinforcement and the laying of concrete 2.

Недостаток известных способов заключаетс в високой материалоемкости фундамента и трудоемкости его возведе .ни ..A disadvantage of the known methods lies in the high material consumption of the basement and the laboriousness of its foundation.

Цель изобретени - снижение материалоемкости фундамента и трудоемкости его возведени .The purpose of the invention is to reduce the material intensity of the foundation and the complexity of its construction.

Указанна цель достигаетс тем, что согласно способу возведени столбчатого фундамента, включающему выполнение опорной плиты, монтаж арматуЕЫ подколонника и наружной oпaлVбки и укладку бетона, после выполнени опорной плиты устанавливают на ней внутри контура подколонника опорную конструкцию , размещают на ней инвентарную раму, оснащенную нат жными приспособлени ми , монтаж арматуры осуществл ют путем подвески ее к раме вокруг опорной конструкщ|и и жесткого прикреплени ее нижних концов к опорной плите, а после монтажа арматуры производ т ее нат жение.This goal is achieved by the fact that, according to the method of erecting a columnar foundation, which includes the construction of a base plate, the installation of the sub-column fittings and the outdoor floor and the laying of concrete, after the base plate is installed, a support frame is installed on it inside the sub-column contour The assembly of the reinforcement is carried out by hanging it to the frame around the supporting structure and rigidly attaching its lower ends to the support plate, and after mounting the reinforcement t recension its tension.

Claims

The method of erection of the foundation includes the installation of the base plate 1, which can be both prefabricated and monolithic, concreted at the construction site. A support structure 2 is installed on the support plate so that it is placed inside the sub-column contour in glass 3, formed in the support plate 1. The support structure can be made as a hollow rack of one or more hollow elements, for example centrifuged tubes. The support structure 2 qi 2 is monolithic in the glass 3. After the support structure is installed, the fitting 4 is assembled, which is assembled in the form of grids and suspended to the inventory frame 5 supported through the jack b on the support structure 2 their lower ends with reinforcement releases are 7 last. Then, the tension grids 4 are tensioned with jacks b, after which formwork 8 is assembled, assembled in the form of ducts. The installation of formwork 6 can be done by hand, with attachment of clamps 9 to the support structure 2. After installation of the formwork, foundation bolts 10 are installed if necessary, for which slots 11 in the frame 5 are provided, and the concrete column is laid down. reduce the laboriousness of the construction and material consumption of the foundation, the claims of the method of erection of the columnar foundation, including the implementation of the base plate, the installation of the under-column and external formwork and way of life for concrete, in order to reduce the material intensity of the foundation and the laboriousness of its erection, after the base plate has been made, a support structure is installed on it inside the contour of the chuck | 1nik: -, the installation of the reinforcement is carried out by suspending it to the frame around the support structure and rigidly attaching the lower ends to the base plate, and after reinforcing the reinforcement, it is tensioned.
