Lead core isolation bearing

Characteristics and application range of isolation rubber bearing   Isolation rubber bearing is composed of multi-layer rubber and multi-layer steel plate or other materials alternately. It is a device with great vertical bearing capacity, small horizontal stiffness and large horizontal lateral displacement tolerance. It can not only solve the horizontal earthquake action, but also bear the vertical earthquake action. It is suitable for the isolation of buildings, bridges, highways, equipment, etc. Eight characteristics of isolation rubber bearing:   1. It has enough vertical stiffness and vertical bearing capacity. 2. The isolation effect is obvious and stable. The horizontal stiffness is small enough to ensure that the basic period of the building is extended to 2-3 seconds or more. 3. Appropriate damping ratio can effectively absorb seismic energy and reduce seismic response of superstructure. 4. It has stable elastic reset function and can automatically and instantaneously reset in multiple earthquakes. 5. The structure is simple and easy to install, detect and repair. 6. It has enough durability and the normal service life of the product is 60 years. 7. Full experience in engineering application and successfully withstood the test of real earthquake. 8. It has the characteristics of resistance to repeated load, fatigue and aging.
