Assembled double steel plate combined shear wall structure with rib plates and construction method of structure

Abstract

The invention provides an assembled double steel plate combined shear wall structure with rib plates. The four rib plates are arranged in the periphery, two steel wall panels are distributed on both sides, and the four rib plates are welded to the two steel wall panels to form a box-shaped shear wall housing; high-strength bolt holes or split bolt holes a are uniformly formed in the rib plates inthe periphery of the shear wall housing; split bolt holes b are neatly formed in the upper portions of the two steel wall panels; studs are neatly and uniformly welded to the interiors of the two steel wall panels; a concrete slab is arranged in the shear wall housing. According to the structure, the crack width of concrete can be effectively controlled, and the concrete can be prevented from being crushed prematurely, so that the deformation capability of the filled concrete is improved; the concrete slab does not directly bear a horizontal load but only serves as the lateral restraint of thesteel wall panels to prevent out-of-plane buckling of the steel wall panels, and cracking of the concrete slab can be reduced; in addition, during practical application, the steel ribs in the shear wall structure not only are the plates for construction assembly but also can improve the rigidity of the outer surface of a wall.

Description

technical field [0001] The invention relates to the field of shear wall structures, in particular to an assembled double steel plate combined shear wall structure with ribs and a construction method thereof. Background technique [0002] In order to meet people's growing needs, high-rise buildings also appear, but the difficulty in structural design of high-rise buildings is to control the lateral movement, and the wall components can significantly improve the lateral stiffness of the structure and reduce the lateral movement of the building, so It is widely used in high-rise buildings. [0003] In the traditional single steel plate shear wall, under the action of horizontal load, extrusion deformation occurs between the corner of the concrete slab and the steel frame, resulting in early cracking or crushing of the corner of the concrete slab, and the concrete at the stud part will follow the corner The mechanical properties of the steel plate without the concrete slab are ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a ribbed assembled double steel plate composite shear wall structure, which solves the problems that the traditional single steel plate shear wall is prone to buckling deformation, and the concrete is not easy to compact, so that the strength of the shear wall is reduced; the invention provides A prefabricated double-steel plate combined shear wall structure with ribs. The concrete is filled inside the steel plate, which can always restrain the steel plate and prevent premature buckling of the steel plate; while the outer steel plate also has a restraining effect on the inner concrete, effectively Control the width of concrete cracks and prevent the concrete from being crushed prematurely, thereby improving the deformation capacity of the filled concrete; in addition, in practical applications, the concrete slab does not directly bear the horizontal load, but only acts as a lateral restraint of the steel plate to prevent out-of-plane buckling of the steel plate , can greatly reduce the cracking of the concrete slab. In addition, in practical applications, the steel ribs in the shear wall structure are not only used for construction assembly, but also can improve the out-of-plane stiffness of the wall.
