Multilayer rubber laminated isolation bearing

Abstract

The invention relates to a multilayer rubber laminated isolation bearing which mainly comprises an upper connecting plate, a lower connecting plate, a laminated rubber elastic body, a steel sheet and a lead core rod, wherein the laminated rubber elastic body and the steel sheet are clamped between the upper connecting plate and the lower connecting plate, and the lead core rod is sealed at the center of the laminated rubber elastic body. Lead cores are poured into a laminated rubber bearing, a plurality of thin rubber layers are laminated to form the laminated rubber elastic body clamped between the upper connecting plate and the lower connecting plate, multilayer rubber is laminated to form a rubber interlayer, so that the initial rigidity and the yield strength of the isolation bearing are improved, the isolation bearing can function in seismic isolation and absorption for house buildings, bridges, precise instruments and the like, horizontal equivalent rigidity is enlarged, horizontal displacement of the isolation bearing is enlarged when an earthquake occurs, the damping property of the bearing is improved, and energy generated by the earthquake is reduced by the aid of horizontally bilateral displacement, so that seismic isolation and absorption are realized.

Description

technical field [0001] The invention relates to a shock-isolation and shock-absorbing multi-layer rubber laminated shock-isolation support, in particular to a special shock-isolation and shock-absorption support suitable for buildings. Background technique [0002] In the construction industry, a new anti-seismic technology is to install laminated seismic isolation rubber bearings between the base layer and the bottom layer of the building. In recent years, my country's rubber bearing technology has entered the period of practical application from the theoretical research stage. With the continuous improvement of people's understanding of new anti-seismic technology, they pay more attention to the various properties of rubber bearings. Due to the small yield load of the traditional laminated seismic isolation bearing, the seismic isolation bearing enters the yield stage during small earthquakes and moderate earthquakes, and the deformation develops rapidly after yielding, w...
