ASTM Standard Bridge Elastomeric Bearings for Phillipine

Hengshui Jianfeng rubber bearing is made of multi layers of natural rubber and thin steel plate mosaic, bonding, curing and become a kind of bridge bearing products.The types of rubber bearings have enough vertical stiffness to withstand the vertical load, and the upper structure of the pressure reliably transfer to the pier; have good flexibility to adapt to the rotation of the beam end; larger shear deformation to meet the horizontal displacement of superstructure.

Detailed description

Bridge plate rubber support by multilayer rubber sheets and thin plate vulcanization, adhesive, it has enough vertical stiffness, the upper structure of the reaction force of reliable transfer to the pier; good elasticity, to adapt to the rotation of the beam end; and larger shear deformation ability, to satisfy the upper structure of the horizontal displacement.
 
The Teflon plate a layer of 1.5mm-3mm in the laminated rubber bearing is stuck to the surface of complex, made into PTFE sliding plate rubber support. In addition to the vertical stiffness and elastic deformation, under vertical load and adapt to the rotation of the beam end, due to the low friction coefficient of PTFE plate, the girder end in PTFE surface free sliding, horizontal displacement is not restricted; is especially suitable for medium, small load, large displacement amount of bridge.
 
Plate rubber bearing not only has excellent technical performance, but also has the advantages of simple structure, low cost, no need of maintenance, easy replacement, buffer isolation, low building height and so on.
