Problems solved by technology

[0002] In the construction site operation, it is often encountered that the distance between the underground foundation pit enclosure structure and the underground external wall is too small, and the external wall construction operation surface is not enough, which leads to the situation that the formwork cannot be supported, which brings inconvenience to the project.

Embodiment Construction

[0023] Such as Figure 1-2 Shown: a shear wall unilateral formwork method, it includes the following steps,

[0024] Step 1: Locate the reinforcement hole on the enclosure grouting pile 1;

[0025] Step 2: filling concrete 7 between the enclosure cast-in-place pile and the shear wall; the inner side of the enclosure cast-in-place pile is isolated by full paving of asphalt felt 6 .

[0026] Step 3: Install formwork on the outside of the shear wall; the formwork is made of plywood with a thickness of 16mm.

[0027] Step 4: Set several vertical inner corrugations 2 on the outside of the formwork, and set horizontal outer corrugations outside the vertical inner corrugations; the vertical inner corrugations use 48×3.0 steel pipes, and the distance between the vertical inner corrugations is 450mm; There are three horizontal outer corrugations, all of which are 48×3.0 steel pipes. The distance between the horizontal outer corrugations is 450mm. The overlapping position cannot be s...

Abstract

The invention relates to a shear wall single-side formwork erecting method, comprising the steps of I, positioning bar embedding holes in an enclosure cast-in-place pile; II, pouring concrete fully between the enclosure cast-in-place pile and a shear wall; III, mounting a formwork outside the shear wall; IV, setting vertical inner ribs and transverse outer ribs on the outer side of the formwork; V, embedding one ends of tie bolts 300 mm in the enclosure cast-in-place pile, and tying the other ends of the tie bolts to the transverse outer ribs; VI, embedding brace fixing members during castingof a floor; VII, mounting inner braces. The field construction difficulty of formwork erection in a place with very small operating space is overcome, construction requirements are met, and the methodis suitable for popularization and use.

Description

technical field [0001] The invention relates to a formwork support method, in particular to a single-side formwork support method for a shear wall. Background technique [0002] In the construction site operation, it is often encountered that the distance between the underground foundation pit enclosure structure and the underground outer wall is too small, and the construction operation surface of the outer wall is not enough, so the formwork cannot be supported, which brings inconvenience to the project. Contents of the invention [0003] The invention aims to overcome the defects of the prior art, and provides a single-side formwork method for a shear wall, which has a simple structure and is easy to install. [0004] In order to solve the problems of the technologies described above, the present invention is achieved in that: [0005] A method for supporting formwork on one side of a shear wall is characterized in that it comprises the following steps, [0006] Step ...
