A combination support reinforcement system and installation and construction method of stiff concrete inclined wall formwork

Abstract

The invention discloses a bracing reinforcement system and an installation construction method of steel reinforced concrete inclined shear wall form assembly, comprising a vertical shear wall and an inclined shear wall inclined upward installed connected with vertical shear wall and opposites with vertical shear wall. The vertical shear wall and inclined shear wall are provided with main body reinforcing bar which is established to be wall frame which is set with formwork outside, and the outside formwork is provided with horizontal main square beam and vertical square beam used for supporting and reinforcement formwork. The horizontal main square beam and vertical square beam are crossed vertically, while horizontal reinforcing bar and inclined upward vertical reinforcing bar are installed between the vertical reinforcing bar and vertical shear wall. The bracing reinforcement system achieves accurate positioning in formwork supporting system and enables all construction loads to transfer to reinforcing bar, which is provided with advantages of simple structure design, easy and fast construction process operation.

Description

technical field [0001] The invention relates to the technical field of formwork support and reinforcement in building construction, in particular to a formwork support and reinforcement system for high, large and thick inclined shear walls and an installation and construction method thereof. Background technique [0002] With the development of the construction industry, the shape of buildings presents complexity and uniqueness, especially for large-scale public and commercial buildings, such as stadiums, art centers, exhibition centers, shopping centers, etc. Shear wall structure. The inclined steel concrete shear wall is outwardly tilted, and the centroid is seriously eccentric. The formwork support produces a tilting force under the action of concrete, section steel, steel bar, formwork quality and construction load. The formwork support system shall be designed to meet the requirements of strength, stiffness, stability and displacement resistance. There are three conve...

AI Technical Summary

Problems solved by technology

There are three conventional formwork reinforcement methods. 1. Encrypted scaffolding. There is a dense scaffolding space, no operating space, and difficult erection. When the basement roof is thin, multi-layer reverse reinforcement needs to be considered. The one-time rental of steel pipe fasteners is relatively large and affects the construction period. ; 2. Lattice type steel support can guarantee the construction quality, but it needs factory processing, a large number of on-site welding, and the one-time cost is relatively high; 3. The combined support of steel wire rope and steel pipe is suitable for inclined shears with low storey height and small inclination angle. force wall, on the contrary, the construction of steel wire rope is difficult to operate, and correspondingly increases the hidden danger of construction safety
