A kind of seismic isolation device for building

Abstract

The invention relates to a seismic isolation device for a building, which relates to the technical field of building construction, comprising a pre-buried upper plate and a pre-buried lower plate, and two connecting parts are arranged symmetrically between the pre-embedded upper plate and the pre-embedded lower plate The inner wall of the connecting plate is provided with a pressure sensor; the lower surface of the pre-embedded upper plate is symmetrically provided with several rails, and a moving block is slidably connected in the rails, and the end of the rails away from the buffer plate is provided with a first pillar , the side of the first pillar close to the moving block is connected with a first push rod, and the first push rod is used to exert a force on the moving block on the same track; the upper surface of the pre-buried lower plate Both sides of the fixed pillar are arranged symmetrically, and a side of the fixed pillar close to the movable plate is provided with a plurality of second push rods, and each of the second push rods is used to apply force to the movable plate opposite to it. The invention effectively improves the shock-isolation efficiency of the shock-isolation device.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a seismic isolation device for building. Background technique [0002] Earthquake is an unavoidable natural phenomenon in human society. 90% or more of the casualties and economic losses caused by earthquakes are caused by the collapse of buildings. Therefore, all countries in the world are committed to doing a good job in earthquake resistance and disaster reduction of projects, and are committed to improving the earthquake resistance level of construction projects and improving the earthquake resistance of construction projects. [0003] The basic seismic isolation technology adopts a flexible connection between the upper structure of the building and the foundation, and sets up a sufficiently safe seismic isolation system. Due to the "shock isolation" and "shock absorption" functions of the seismic isolation layer, the upper structure performs approximately trans...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the present invention provides a kind of seismic isolation device for building, which is used to overcome the problem of low seismic isolation efficiency caused by the inability of the seismic isolation device in the prior art to adjust its own shock absorption state in real time according to the earthquake intensity.
