Product Description
Bridge/Road Steel and Rubber Laminated Bearing Pad
Bridge rubber bearing is made of multilayer natural rubber and sheet steel after inlay, conglutinate, vulcanization. It has enough vertical stiffness to support vertical load, and it could deliver the pressure of superstructure to abutment.
There are two shapes: Rectangle and round. And the type with 1.5-3mm tetrafluoroethylene on the elastomeric bearing makes the superstructure of bridge horizontal displacement unrestricted.
Elastomeric bearing is widely used in building bridge, water and electricity project, building anti-seismic facility and so on. It has simple structure, easy installation, saving steels, low price, easy and convenient conservation and change and so on.
