Edge member and construction method of steel concrete shear wall

Abstract

The invention discloses a shape steel concrete shear wall edge member and a construction method thereof and belongs to the field of construction engineering. The shape steel concrete shear wall edge member mainly comprises an open square steel pipe, a thin-walled shape steel truss, wall body horizontal distribution steel bars, edge member stirrups, cement pressure plates, self-tapping nails, longitudinal force-bearing steel bars of the shear wall edge member and the like. The open square steel pipe and the thin-walled shape steel truss serve as reinforcing bars of the shear wall edge member, can improve the performance of a shear wall, and meanwhile can further serve as fixing pieces of a disassembly-free formwork, thus one piece with multiple purposes is achieved, and in order to increasethe building industrialization level, the construction method, good in quality, high in construction speed, efficient and low in consumption, of a fabricated concrete shear wall structure building isprovided.

Description

technical field [0001] The invention belongs to the field of construction engineering, and relates to a concrete shear wall structure, in particular to an edge component of a steel concrete shear wall and a construction method. Background technique [0002] For a long time, in order to improve the performance of concrete shear wall structures, building structural engineering technicians and scientific researchers have achieved their goals by arranging steel in the edge components of concrete shear walls. He has done a lot of research work and achieved fruitful scientific research results. [0003] In recent years, with the demand for building industrialization and the rise of prefabricated buildings, research and technological innovations on the edge components of steel concrete shear walls used in prefabricated concrete structures have continued to emerge. The retrieved technical documents include: [0004] 1. The invention patent application of application publication num...

Problems solved by technology

[0005] However, the problems in this invention application are: the processing of the hemmed U-shaped steel plate arranged at the end of the wall is difficult, which is not conducive to industrial production, the production efficiency is low, and the cost is pushed up; the steel structure is exposed, and fireproof coating must be adopted, which not only increases cost, and how to coordinate the wall section with the concrete wall is also very troublesome; the embodiment only has "line-shaped" shear walls, and how to solve "T-shaped" and "L-shaped" shear walls must be quite difficult. Therefore, it is difficult for the invention application to be practicable

[0010] Most of the existing steel-concrete shear wall edge members and construction technologies use steel to enhance the performance of the shear wall structure, and there is no use of steel as both the reinforcement of the edge members of the shear wall and as an enhancement of the shear wall structure. At the same time, it can also be used as a fixing part without dismantling the formwork to achieve a multi-purpose effect, so as to improve the level of building industrialization and open up an implementation mode of high-efficiency and low-consumption prefabricated concrete shear wall structure buildings.
