An anti-seismic device for a building structure

Abstract

The invention relates to the technical field of construction engineering, in particular to an anti-seismic device for a building structure, comprising: a base, a first connecting piece and a second connecting piece are sequentially sleeved on the outside of the base from inside to outside, and the first connecting piece and the second connecting piece A buffer space is reserved in the radial direction between the pieces, the second connecting piece covers the top surface of the base, and a second telescopic piece is installed vertically between the top surface of the base; the support piece is located in the buffer space , one end runs through the second connecting piece, the other end is connected to the first connecting piece, the second connecting piece is slidingly connected to the support piece; the first telescopic piece is installed vertically on the side wall of the base, and one end is fixedly connected to the base, The other end is fixedly connected with the first connecting piece. When subjected to external vibration, the second connecting piece drives the first telescopic piece to move up and down through the first connecting piece, and the support piece will not drive the first connecting piece to move when sliding in the horizontal direction, and the horizontal shock absorption will not affect the longitudinal shock absorption. The effect is to ensure the safe and stable operation of the anti-seismic device of the building structure.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an anti-seismic device for a building structure. Background technique [0002] Building structures sensitive to vibration, such as bridges, buildings and other building structures, need to design effective anti-seismic structures or install anti-seismic devices during the construction process, so that the building structures can effectively resist vibration during use to avoid building structures. Damaged due to shock. When the building structure vibrates, the shock-absorbing structure consumes the energy generated by the vibration by stretching and shaking itself, so as to maintain the safety and stability of the building above the shock-absorbing structure. However, the anti-seismic devices in the prior art are usually a simple combination of a transverse shock absorbing mechanism and a longitudinal shock absorbing mechanism. In the vertical direction, the sh...

Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the interaction between the horizontal shock absorbing mechanism and the longitudinal shock absorbing mechanism will lead to the reduction of the shock absorbing effect of the longitudinal shock absorbing mechanism, thereby providing a building structure anti-seismic device
