Deformation joint post-section shear wall sliding-pushing type installation and disassembling template erection system and construction method

Abstract

The invention relates to a deformation joint post-section shear wall sliding-pushing type installation and disassembling template erection system and a construction method. The construction method comprises the main construction steps of: installing a sliding guide rail; installing a sliding type single-sided bracket; pushing off an inside template by utilizing a screwing pushing device; recovering the sliding type single-sided bracket; hanging an outside template away. According to the invention, the templates are supported by utilizing a supporting steel pipe extending out of the sliding guide rail, and the sliding type single-sided bracket and cross-pulling screws are combined so as to fix the templates; then by screwing the screwing pushing device and further pushing the cross-pullingscrews, the inside template is pushed away; finally, the sliding-type single-sided bracket is recovered and the outside template is hung away. According to the invention, components mostly are precastand recoverable; the template erection system is convenient to install and rapid in construction; meanwhile, a constructed shear wall is high in quality and high in template recyclability rate; problems of a great amount of consumables for installing and disassembling the templates, long period, easiness for damaging the templates and the shear wall and the like in the prior art are solved; the deformation joint post-section shear wall sliding-pushing type installation and disassembling template erection system and the construction method are obvious in economic beneficial effects.

Description

technical field [0001] The invention relates to a push-pull formwork support system and construction method for a shear wall with narrow deformation joints, which belongs to the field of construction engineering and is suitable for the construction of a shear wall formwork project in a post-deformation joint section of a high-rise building structure. Background technique [0002] In construction engineering, the installation method and quality control of the shear wall formwork in the rear section of the high-rise shear wall structure have always been difficult in construction. The traditional polystyrene board formwork method has the following problems: First, the side of the poured concrete will be The extrusion of the polystyrene board to the other side resulted in no protective layer for the reinforcement on the other side, and the polystyrene board could not be taken out, resulting in waste; second, due to the limitation of the existing shear wall in the previous section...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the polystyrene board is easy to move during pouring, and the polystyrene board cannot be taken out to cause waste when the traditional polystyrene board post-work section shear wall formwork is erected, the formwork installation and disassembly period is long, and the wooden wedge type wooden square support Due to problems such as poor reliability and easily damaged formwork by crowbar-type formwork removal, a formwork support system and construction method of sliding and pushing-type installation and removal of shear walls in the section behind deformation joints are proposed. This method uses the support protruding from the sliding guide rail The steel pipe supports the formwork, combined with the sliding single-side bracket and the pull screw to fix the formwork, and then pushes the pull screw to push the outer formwork away by screwing the jacking device, and finally recovers the slide-type single-side support and lifts it away The inner formwork solves the difficulty of dismantling the formwork engineering support in the rear section of the deformation joint and the problems of labor and materials, saves the cost of formwork support, avoids formwork damage, improves work efficiency, and increases the number of formwork turnover
