Rubber bearings (, series) are made of multi-layer rubber and thin steel plates inlaid, bonded and vulcanized. The product has sufficient vertical stiffness to withstand vertical loads and can reliably transmit the pressure of the superstructure to the pier. It has good elasticity to adapt to the rotation of the beam end and large shear deformation to meet the horizontal displacement of the superstructure. It has the characteristics of simple structure, safety and convenience, steel saving, low price, simple maintenance and easy replacement. This product has a good anti-seismic effect and can reduce the impact of dynamic loads on the bridge span structure and piers. Classification and representation of rubber bearings
According to the structural types of bridge plate rubber bearings, they are classified as follows:
Spherical crown disc rubber bearings (B series)
Ordinary plate rubber bearings - Rectangular ordinary plate rubber bearing (series)
Round ordinary plate rubber bearing (series)
Rubber bearing
Circular PTFE plate rubber bearing (series)
Poly PTFE Plate Rubber Bearing - Rectangular PTFE Plate Rubber Bearing (Series)
Spherical Crown PTFE Plate Rubber Bearing (B Series)
Plate rubber bearings are classified as follows according to the applicable temperature of the rubber type. :
, Neoprene rubber: Applicable temperature ﹢℃∽-℃
b. Natural rubber: Applicable temperature ﹢℃∽-℃
, EPDM rubber: Applicable temperature ﹢℃∽- ℃
