Description

Laminated Rubber Bearing Pads is usualy made of rubber and steel plate, Each layer of rubber and steel plate after vulcanizing with its strong bonding become one together, Main function is to transfer the counterforce reliably of the upper structure to the pier, and at the same time can finish the deformation of beam body structure needed.

Feature

a. Simple structure, easy manufacturing, low cost, save steel
b. Material source is adequate, adaptable to finalize the batch production.
c. rubber has good elasticity and damping, and rubber bearing has good shock absorption performance, can reduce the dynamic load on the bridge span structure and the impact of the pile, so as to improve the stress of the bridge.
d. building height is low, easy installation, can save labor and construction time.Easy to change, also can be replaced bearing in operation of the bridge.
e. rubber bearing pads under the action of vertical force occur only very small elastic deformation, and under the action of horizontal force of shear deformation can occur in any direction in the plane of the horizon, and a wide range of application, able to adapt to wide bridge, curved bridge and skew bridge.
f. rubber bearing performance is reliable.
