Device and method for reinforcing formwork on single-side of retaining wall of basement

Abstract

The invention discloses a device and method for reinforcing a formwork on a single-side of a retaining wall of a basement, and belongs to the technical field of house building construction. Scaffolds are arranged in a storey, and horizontal rods of the scaffolds serve as horizontal supports; formworks, secondary beams and primary beams are arranged on one side, facing the interior, of the retaining wall sequentially, the multiple secondary beams are vertically arranged in parallel, and the multiple sets of primary beams are horizontally arranged in parallel; each set of primary beams is fixedly connected with embedded rebars in a retaining pile of a foundation pit through a plurality of waterproof screw rods which penetrate through the primary beams, the secondary beams and the formworks to form a rowed anchor structure ; a plurality rows of positioning piles are arranged in a floor face in a buried mode, and a plurality rows of lateral supports corresponding to the positioning piles are connected with the positioning piles and the primary beams; and an anti-floating pulling rod is arranged in the floor face which is close to the lowest row of primary beams in a buried mode, and the anti-floating pulling rod is fixedly pulled and tied with the lowest row of primary beams through hooks. The device and method for reinforcing the formwork on the single-side of the retaining wall of the basement solves the problems that, in the prior art, mounting and dismounting in the storey is difficult, the turnover utilization rate is low, the reinforced frame body is unable to be connected with the scaffolds effectively, and a storey wall and a beam plate are unable to be formed for one time.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a retaining wall of a basement constructed with single-side formwork. Background technique [0002] Because a project of the applicant is adjacent to the subway line, the support structure on the west side of the foundation pit is retaining wall pile + reinforced concrete inner support. The depth of the foundation pit is about 20m, and the distance between the basement retaining wall and the retaining wall pile near the subway entrance is only 350mm. The installation of conventional wall formwork cannot be satisfied, so only one-side support formwork can be used to construct the basement retaining wall. [0003] Existing construction techniques all have respective defects: [0004] 1. Shaped tool support system (tripod). It is shaped and produced in the factory into a tripod-like reinforced frame, and assembled on site. The cost of using this method is high, and ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to propose a reinforcement device and method for one-side support formwork of a retaining wall in a basement, which solves the difficulty of installation and disassembly in the floor of the prior art, the low turnover utilization rate, the inability of the reinforcement frame to be effectively connected with the hall frame, and the problems of the floor wall and the floor wall. The problem that the beam and slab cannot be formed at one time
