Product Description

Product Description

Jingtong  rubber Isolator bearing  (LRB) ,  lead core bridge rubber bearing

This kind product includes: Elstomeric Seismic protection isolator for bridge and building. It can absordb earthquake energy effectively by way of rubber's elasticity and Lead's restorability. Products comply with:JT/T822-2011 Lead rubber bearing isolator for highseimic protection isolator for buildings.
 
Features

1)Stiff ands strong in vertical direction but flexible in horizontal direction.
2)Absorb earthquake-generated force by changing the bearing's shape.
3)Allow the building to retain their original shapes and position owing to the high elastic force of rubber 
4) Capable to adjust damping amount just by changing the number of lead plugs
5)Easy to install without a separated damper
6) Low maintenance.

Application:

Lead rubber bearing, main branch of seismic isolation system, is widely applied to the large sized structures such as road bridges, rail bridges and nuclear power station to minimize damages from dynamic loads like earthquake.
