Detachable assembled shear wall structure with replaceable component and assembling method

Abstract

The invention provides a detachable assembled shear wall structure with replaceable components and an assembling method. Precast shear walls and a foundation and upper and lower layers of precast shear walls are both connected with each other through the replaceable components; and the precast shear walls and a precast floor slab are connected with each other through common bolts. According to thedetachable assembled shear wall structure with the replaceable components, each member and the replaceable components can be all precast in a factory and can be mounted after being transported to thesite. The precast shear walls are reinforced concrete shear walls which are industrially made and produced in a prefabrication factory. The precast floor slab is a reinforced concrete floor slab which is industrially made and produced in the prefabrication factory. According to the detachable assembled shear wall structure with the replaceable components, the detachability of the shear wall and the quick recovery of the structure after earthquake are realized, and requirements of structure assembled construction and building industrialization are satisfied.

Description

technical field [0001] The invention belongs to the field of prefabricated structural systems and the field of anti-seismic structural systems, in particular to a detachable prefabricated shear wall bolt connection structure and an assembly method. Background technique [0002] The so-called detachable design means that through effective design, all components and parts of the house can be completely disassembled to realize recycling and reuse. Through the detachable design of materials, components, structures, etc., the damaged parts of the house can be replaced, and the damaged structure can be disassembled, so as to achieve the goals of reusing components and recyclable materials, so as to realize the sustainable development of the construction industry. [0003] The key issue for the detachable function of prefabricated concrete structures lies in the development of detachable connections. At present, the connection methods of prefabricated concrete structure system...

AI Technical Summary

Problems solved by technology

[0004] (1) A large number of shear cracks are prone to appear in the concrete around the bolt holes reserved at the end of the wall due to the action of bolts and pins, resulting in shear failure of the wall concrete at the bolt connection, which in turn affects the seismic performance of the structural system;

[0005] (2) The floor slab connection overlaps with the wall slab joints, making it impossible to disassemble the structural system;

[0006] (3) Most of the existing bolted connections are prone to slippage, resulting in local damage to the wall and other components, which in turn affects the seismic performance of the structural system;

[0007] (4) Due to the existence of a large number of embedded parts in the existing bolted connection, the structure of the connection node is complicated and the steel consumption is large
