Short-leg shear wall formwork erecting method

Abstract

The invention relates to a short-leg shear wall formwork erecting method. The method includes following steps: making L-shaped shaping square steel pipe main edges, and making short-leg shear wall endL-shaped split bolts; assembling short-leg shear wall formworks; paving vertical secondary edges according a formwork calculation result; paving main edges, wherein two L-shaped square steel pipe shaping dies completed by welding are adopted as the main edges of short-leg shear wall inside corners; assembling short-leg shear wall end formworks; adopting double steel pipes to cooperate with the L-shaped split bolts to reinforce the short-leg shear wall end formworks; hooking one ends of the L-shaped split bolts onto steel pipes at wall corners at outside corners, and adopting Shanxing clamps to cooperate with nuts to fix the double steel pipes at the other ends. The method is simple and convenient in construction, wall cast-in-place quality is improved, subsequent maintenance time is reduced, and working efficiency is improved; integral quality of a concrete cast-in-place structure is ensured, construction process is simplified, and construction period is shortened.

Description

technical field [0001] The invention relates to a building construction method, in particular to a formwork support method for short limb shear walls. Background technique [0002] At present, many residential projects use short-leg shear walls to meet people's requirements for space division, which are divided into Z-type, L-type, T-type, I-type, I-type and cross-type. During the construction of the traditional short-leg shear wall, the surrounding formwork uses wooden squares as the secondary flute, and double steel pipes as the main flute, which are fixed by tension bolts. Since the steel pipes are cylindrical, there are gaps at the male and female corners of the two short-leg shear walls. It is difficult to control the size of the yin and yang corners. When setting up the formwork, a wooden square is generally added to the inner corner of the short-leg shear wall for reinforcement, but because the contact surface between the wooden square and the steel pipe is small, an...

Problems solved by technology

During the construction of the traditional short-leg shear wall, the surrounding formwork uses wooden squares as the secondary flute, and double steel pipes as the main flute, which are fixed by tension bolts. Since the steel pipes are cylindrical, there are gaps at the male and female corners of the two short-leg shear walls. It is difficult to control the size of the male and female corners

When setting up the formwork, a wooden square is generally added to the inner corner of the short-leg shear wall for reinforcement, but because the contact surface between the wooden square and the steel pipe is small, and the two short-leg wall steel pipes are disconnected, the integrity of the formwork support is poor , when pouring concrete, it is easy to cause expansion and displacement

After the formwork is removed, the yin and yang corners are not smooth, which cannot meet the current project's requirements for actual measurement and measurement

In order to meet the requirements of actual measurement and measurement, it is often necessary to carry out a large number of repair work on defective parts, which increases the amount of repair work and affects the overall appearance of the cast-in-place structure.
