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.

The bearing capacity of the rubber bearing of the bridge depends on the following three conditions
(1) rubber itself crushed or cut bad;
(2) rubber is produced more than the use of the compression deformation and shear deformation;
(3) compression support material (concrete, steel or other) is the rubber outward reverse horizontal shear tensile or shear when support and rubber contact surface between the slip.
Through a lot of experiments, it is proved that the bridge rubber bearing surface of the rubber with compressive strength and shear strength, rarely be crushed or cut bad. Here to introduce rubber bearings, rubber material is artificial synthesis of chloroprene rubber (also known as NAT rubber and vulcanized natural rubber. By using butyl rubber and rubber mix. When rubber bearing strength calculation of allowable stress is determined by (2), (3) under the condition of bearing capacity.
