Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, and more specifically to a building seismic isolation device. Background Art

[0002] Building seismic isolation devices are technical devices used to reduce the damage caused by earthquakes to buildings. They can reduce the transmission of seismic energy to the building structure when an earthquake occurs, thereby protecting the building from serious damage. Seismic isolation devices can reduce the impact of earthquakes on buildings by shock absorption and isolation, and improve the seismic resistance of buildings.

[0003] Most existing building seismic isolation devices are connected by shock absorbers and seismic isolation supports. When used for a long time or encountering large vibrations, the shock absorbers will deform or even break, thereby reducing the shock absorption effect. In addition, they are usually cast and fixed with concrete during use. When disassembly and replacement are required, it is troublesome to chisel open the base and replace it. Utility Model Content

When the bottom plate 101 and the top plate 104 are subjected to excessive pressure, the first supporting main column 102 and the shock-absorbing rod 105 are prevented from being deformed or broken due to excessive pressure.

The distance between the rings 205 sleeved on the outside of the sleeve 204 is reduced, and the two groups of inner rods 202 inside the sleeve 204 are in contact, so that the structural strength between the bottom plate 101 and the top plate 104 is stronger.
