Prefabricated steel-confined concrete shear wall structure

Abstract

A prefabricated steel-confined concrete shear wall structure, including vertical and horizontal wall panels, is characterized in that: the end of the prefabricated shear wall vertical and horizontal wall panels is equipped with H-shaped steel and the flange on one side of the H-shaped steel is exposed, and the core area of ​​the node is provided with a A steel pipe, the exposed H-shaped steel flange is vertically connected to a patch plate at intervals, and the other end of the patch plate is fixed on the steel pipe, so that the H-shaped steel and the square steel pipe are connected by the patch plate to form the skeleton of the node area, and the skeleton of the node area is poured Concrete is connected with vertical and horizontal wall panels to form an integral shear wall. The invention connects the vertical and horizontal wall panels and the core steel pipes into a whole through the patch panel, and the concrete in the joint area is restrained by the steel skeleton, so the seismic performance is improved, so that the structural system has good overall performance. The construction process of the structural system is simple, it is convenient to support the formwork and reduce the wet work load on the construction site.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a structural system of an assembled section steel confined concrete shear wall. Background technique [0002] The prefabricated assembly shear wall structure is a relatively common form in the assembly structure. The structure is composed of basic components such as prefabricated shear wall panels. The components are pre-fabricated in the factory and then installed on the construction site. A series of advantages such as fast speed and low construction cost have become a strong support for the modernization of the construction industry. [0003] The performance of connecting nodes is an important factor affecting the integrity of prefabricated structures, and a large number of earthquake damage shows that the damage of prefabricated structures is mostly concentrated at the nodes. Nowadays, the vertical and horizontal walls of prefabricated shear walls mainly adopt the ...

AI Technical Summary

Problems solved by technology

Nowadays, the vertical and horizontal walls of prefabricated shear walls mainly adopt the connection technology of combining horizontal reinforcement rings and vertical insertion bars. Because this kind of connection is not enough for the concrete constraints at the joints, during earthquakes, the joints will be under the repeated action of bending moment and shear force. The concrete is crushed and falls off, and the steel bars gradually fail, eventually leading to the destruction of the entire structure, and the structure in the joint area is complex, the construction is difficult, and it is difficult to ensure the construction quality
