Concrete-filled steel tube row column type connection prefabricated shear wall structure and construction method

Abstract

The invention discloses a concrete-filled steel tube row column type connection prefabricated shear wall structure and a construction method, the concrete-filled steel tube row column type connection prefabricated shear wall structure comprises a prefabricated shear wall, row column connection components and laminated slabs which are connected with one another, the multiple groups of row column connection components are arranged in the prefabricated shear wall at intervals, and the laminated slabs are fixed on the prefabricated shear wall in a penetrating and inserting manner; the concrete-filled steel tube row column connecting component is connected with the prefabricated shear wall and the laminated slab, the application range of the concrete-filled steel tube is widened, the structure is very novel, due to the application of the concrete-filled steel tube row columns, the connecting bearing capacity is high, the anti-seismic ductility is good, the problem that concrete of the shear wall structure is prone to being damaged at the bottom is solved, and connection is reliable.

Description

technical field [0001] The invention is applied to the field of prefabricated assembled structures in civil engineering, and in particular relates to a prefabricated shear wall structure and a construction method of concrete filled steel tube column-connected prefabricated shear walls. Background technique [0002] The prefabricated shear wall structure adapts to the development needs of modern green construction. It is a structure that is vigorously promoted and has been applied in many projects. In the prefabricated shear wall structure, the joint performance of the upper and lower shear walls is the key to the connection, and whether the connection is reliable directly affects the structural safety. The connection between prefabricated shear walls and floors is also a key issue in the construction of prefabricated shear wall structures. [0003] At present, laminated slabs are often used in projects. The connection method between the upper and lower prefabricated shear w...

AI Technical Summary

Problems solved by technology

This connection method has a great impact on construction, the grouting quality cannot be detected, and the process is relatively complicated. Moreover, the steel bars of the shear wall are only connected at the edge member positions, and other parts are connected at intervals. This cannot ensure reliable structural connection, and the safety problem is obvious. The seismic performance and ductility are poor. In addition, after the composite slab concrete is poured, it needs to be cured for a period of time before the upper shear wall can be constructed, which affects the construction progress

[0004] The rigidity of traditional cast-in-place shear wall structures and prefabricated shear wall structures is too large, and the shear wall concrete is obviously damaged under earthquake action, and the energy dissipation capacity is very poor
