Steel frame-fabricated integral reinforced concrete shear wall structure system

Abstract

The invention discloses a steel frame-fabricated integral reinforced concrete shear wall structure system and an implementation method thereof. The structure system comprises a steel frame, prefabricated wall panels and a cast-in-place reinforced concrete shear wall, wherein the steel frame is composed of steel columns and steel beams. The fabricated integral shear wall is composed of the two prefabricated wall panels, stressed steel bars and cast-in-place concrete. Firstly, the prefabricated wall panels and the steel columns are positioned and installed on site through embedded steel angles, then, the stressed steel bars are arranged and distributed in the two wall panels, and finally the concrete is poured into the wall panels, so that the integral structure of the steel columns, the prefabricated wall panels and the core shear wall is formed. The structure system has high lateral stiffness on the premise that the section of steel members is not increased, and the prefabricated wall panels can replace form boards in a traditional process, so that the working efficiency of the construction site is greatly improved. The structure system can achieve standardization and modularization of building structure members, meet the demands of building fabrication industrialization and be widely applied to steel structure high-rises.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and relates to a steel frame-assembled integrated reinforced concrete shear wall structure system and an implementation method thereof. Background technique [0002] The prefabricated structure is the product of industrialized mass production, and has the advantages of fast construction pace, good product quality, low budget cost, high construction efficiency, and simple production process. Prefabricated components are easy to produce and maintain, have high economic benefits, and have a wide range of applications, which is in line with the current development trend of my country's construction industrialization. The steel frame can realize the prefabrication of the structure very well, and has the characteristics of large building space and flexible layout. However, for high-rise building structures, the lateral stiffness of the steel frame is relatively insufficient. Reinforced ...

AI Technical Summary

Problems solved by technology

Reinforced concrete shear wall can effectively improve the lateral stiffness of the structure, improve the seismic performance of the structure, and has good economic benefits, but the traditional shear wall process requires a series of cumbersome steps such as erecting formwork, support, maintenance, and formwork removal. The technological process cannot be assembled and constructed simultaneously with the steel frame, and the connection between the prefabricated shear wall and the steel frame is not reliable and stable enough to ensure the integrity of the structural system
