A detachable assembled shear wall structure spliced ​​by bolts

Abstract

The invention discloses a bolt-jointed detachable assembled shear wall structure. The connection schemes of the detachable bolt-jointed assembled shear wall structure system are divided into horizontal seam connection, vertical seam connection and floor slab connection. The invention has the advantages of easy disassembly, easy repair, reusability, etc., and is beneficial to realize the detachable function of the structure and the fast repairable function after an earthquake. In the present invention, both the horizontal joints and the vertical joints are spliced ​​by bolts, without pouring concrete or mortar, and all components can be disassembled. At the same time, the present invention mainly concentrates energy consumption and damage on the replaceable connecting steel plates, which is beneficial to the repair or replacement of the replaceable connecting steel plates after strong earthquakes, and achieves the purpose of quickly repairing the structure after earthquakes.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structures and assembled structures, in particular to a detachable assembled shear wall structure spliced ​​by bolts. Background technique [0002] The traditional seismic design realizes the energy dissipation of the structure under the earthquake through the ductility design, so as to avoid the brittle failure or even collapse of the structure. The ductility of the structure is manifested by the plastic deformation of the main anti-lateral force components, and the plastic deformation in the structure will cause damage and residual deformation of the structural components, and eventually cause the structure to be damaged and lose its function. Therefore, traditional anti-seismic structures focus on protecting life when an earthquake occurs, while ignoring the consequences that the structure cannot bear the original function for a long time after the earthquake. With the advancement of anti...

AI Technical Summary

Problems solved by technology

[0005] (1) Mortar needs to be poured into the reserved hole on the wall to ensure reliable connection, so that the wall cannot be disassembled;

[0006] (2) The floor slab connection overlaps with the wall slab joints, making it impossible to disassemble the structural system;

[0007] (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;

[0008] (4) Due to the existence of a large number of embedded parts in the existing bolted connection, the structure of the connection node is complex and the amount of steel used is large
