Anti-seismic shear wall

Abstract

The invention discloses an anti-seismic shear wall. The anti-seismic shear wall comprises two stand columns, a lower wall body unit and an upper wall body unit. The lower wall body unit is integrallycast with the two stand columns in the same layer, and a gap exists between the upper wall body unit and the two stand columns in the same layer. Bumps are arranged at the bottom of the upper wall body unit, pits corresponding to the bumps are arranged at the top of the lower wall body unit, the pits are internally provided with left and right two lifting surfaces for lifting the bumps when the bumps moves laterally to convert kinetic energy into gravitational potential energy, bottom planes for providing transverse moving distance for the bumps are further arranged between the two lifting surfaces of the pits, and the bumps are positioned in the corresponding pits. Weak connection keys protruding outward from the surfaces of the two wall body units are arranged between the lower wall bodyunit and the upper wall body unit. The anti-seismic shear wall can effectively transform and dissipate seismic energy, and can prevent the wall body and the stand columns from being damaged as the whole at a time, and the post-earthquake repair process is quick and convenient.

Description

Technical field [0001] The invention relates to the technical field of construction of a seismic shear wall, in particular to a seismic shear wall. Background technique [0002] Shear wall refers to the wall in the building that resists horizontal shear force. Because the horizontal shear force to be resisted by high-rise buildings is mainly caused by earthquakes, shear walls are also called seismic walls. [0003] Most of the shear walls in the prior art are frame-shear structures, which include two uprights and multiple beams of different heights. Both ends of each beam are fixed to the two uprights. The number of stories is counted from the ground up. In other words, the ground, the two sections of columns on this floor, and the beams of the first layer constitute the frame unit, while for other layers, the beams of the next layer, the beams of this layer and the two sections of columns of this layer constitute the frame unit. Wall concrete units are poured into each frame uni...

AI Technical Summary

Problems solved by technology

[0005] From the structure and construction method of the above-mentioned frame shear wall, it can be seen that the frame unit of each floor of the frame shear structure and the wall concrete unit in the frame unit are all one-time pouring and molding as a whole. When an earthquake occurs, this structure will It is easy to be damaged by the earthquake force as a whole, causing the building to collapse, and the earthquake resistance effect is very poor
