Three-dimensional shock-isolation damping supporting seat and building

Abstract

The invention provides a three-dimensional shock-isolation damping supporting seat and a building, and relates to the technical field of building shock isolation. The three-dimensional shock-isolationdamping supporting seat comprises an upper blanking plate, a lower blanking plate, a plurality of rubber layers and a plurality of layers of reinforcing plates, the upper blanking plate and the lowerblanking plate are oppositely arranged, the rubber layers and the reinforcing plates are both alternately arranged between the upper blanking plate and the lower blanking plate, and lead cores and elastic pieces are arranged in the rubber layers and the reinforcing plates in a penetrating mode. According to the three-dimensional shock-isolation damping supporting seat, the technical problems thatthe vertical rigidity of a shock-isolation supporting seat in the prior art is low, and the shock-isolation supporting seat is prone to being damaged are solved.

Description

technical field [0001] The invention relates to the technical field of building shock isolation, in particular to a three-dimensional shock-isolation damping support and a building. Background technique [0002] Seismic isolation technology can effectively reduce the seismic response of houses. In China, more than 500 engineering projects have adopted seismic isolation bearings, including houses, bridges and expressways. The seismic isolation structure prolongs the period of the upper structure by arranging isolation bearings on the isolation layer, avoids the excellent period of the earthquake, isolates the seismic capacity from being transmitted to the upper structure, and assists in the consumption of the damper, which can effectively consume the seismic energy. [0003] The vibration isolation bearing in the prior art usually achieves the vibration isolation effect by increasing the thickness of the rubber layer and reducing the vertical stiffness of the vibration isolat...

AI Technical Summary

Problems solved by technology

Due to the increased height, the anti-overturning performance of the isolation bearing is reduced, and it is prone to instability. Therefore, the horizontal deformation is generally set within 100%, which can only guarantee the deformation requirements under small earthquakes, but cannot meet the deformation requirements under large earthquakes.

Moreover, due to the small vertical stiffness, the rubber bulges violently, which is easy to cause early damage and reduce the service life
