Fabricated shear wall with steel plate stud combined type diagonal bracing and construction method

Abstract

The invention discloses a fabricated shear wall with a steel plate stud combined type diagonal bracing and a construction method. The fabricated shear wall comprises a first shear wall unit and a second shear wall unit, wherein the first shear wall unit and the second shear wall unit are stacked up and down, and the first shear wall unit and the second shear wall unit are connected and fixed witha connecting mechanism; the first shear wall unit and the second shear wall unit are provided with shear wall structures; a shear wall frame is formed by enclosing a left concealed column, an upper concealed beam, a right concealed column and a lower concealed frame; a first facade steel plate and a second facade steel plate are fixed to the front side and the rear side of the shear wall frame; diagonal bracing members are fixed in the shear wall frame; and each diagonal bracing member comprises two steel plates, the two steel plates cross each other to form an X-shape structure, studs are arranged on the steel plates, and concrete is poured in the shear wall units. According to the fabricated shear wall with the steel plate stud combined type diagonal bracing and the construction method,the in-plane lateral stiffness, shear bearing capacity, bending bearing capacity, ductility and energy consumption of the shear wall are improved through the design of the diagonal bracing members, the shear wall units can be pre-installed in advance, and on-site construction is facilitated.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated shear wall with steel plate stud combined diagonal braces and a construction method. Background technique [0002] In the super high-rise hybrid structure system, the shear wall is an important lateral force-resisting component. As the height of the building structure increases, ordinary cast-in-place reinforced concrete shear walls cannot meet the requirements of building use, and the economic benefits are poor. [0003] The use of double-layer steel plate-concrete composite shear walls gives full play to the advantages of large lateral stiffness of reinforced concrete structures and good ductility of steel structures, improves the bearing capacity and seismic performance of shear walls, and avoids poor ductility and energy consumption of reinforced concrete structures. Poor and steel structures have poor lateral resistance and are prone to loca...

AI Technical Summary

Problems solved by technology

However, reinforced concrete shear walls with hidden supports formed by adding longitudinal bars and stirrups or reinforced concrete shear walls with section steel supports will have the problems of excessive local reinforcement and complicated structural forms, which will increase the difficulty of on-site construction and require high technical level of on-site construction personnel. ; The welding workload is heavy, and the quality of on-site welding is difficult to guarantee, etc.
