Rubber bridge bearing is sulfurized and stuck gether by several layers of rubber sheet and thin steel plate. It hassufficient vertical rigidity, and can reliably transfer the counterforce on the upper structures to pier platform; it has fine elasticity, and can adapt to the rotation of beam end; Rubber bridge bearing has great shearing deformation capacity, and can satisfy the horizontal displacement of the upper structures.
Adhere a layer of 1.5mm to 3mm thick polytetrafluoroethylene plate on the surface of the above Rubber bridge bearing,and polytetrafluoroethylene sliding Tetrafluoro plate Bearing is formed. Besides vertical rigidity and elastic deformation,able to endure vertical load and suit to the rotation of beam end, the beam end can freely slide on the surface of the tetrafluoro plate due to the low friction coefficient of the polytetrafluoroethylene plate, and the horizontal displacement isnot limited; it specially suit to bridges with medium or low load and large displancement.
Tetrafluoro plate Bearings not only has fine technical performances, but also has simple structure, low price, no maintenance, easy to change, buffering and shock is isolating, low building height, and other characteristics. Therefore, rubber bridge bearing is welcomed and widely used in bridges.
Aplication of Rubber bridge bearing
1. Rubber bridge bearing suits to bridges with span less than 30m and small displacement. Different flat shape suitsto different bridge span structures: orthogonal bridges adopt rectangular bearing; curvilinear bridges, obique crossing bridges and cylindrical pier bridges adopt circular bearing.
2. Tetrafluoro rubber bridge bearing suits to bridges with large span, several spans in continuous, with simply supported beam and continuous plates strutures, and large displacement. It can still be used as the sliding block inpushing of continuous beam and cross sliding of T-shaped beam. The application of rectangular and circular tetrafloro Elastomeric Laminated Bearings are the same with rectangular and circular general Bridge Bearing ,separately.
Classification and representation methods of Rubber bridge bearing
(1) Classification as shapes of rubber bridge bearing

b.NR bearing (applicable temperature -35~60°C)
c.EPDM bearing (applicable temperature -40~60°C )
(3) Classification as structure style of neoprene bearing
a.General plate type neoprener bearing
b.Tetrafluoro sliding plate type neoprene bearing
The operating principle of Rubber bridge bearing
The main function of Neoprene bearing is reliably transfer the counterforce on the upper structures to pier platform, and meet the need deformation of beam body ( horizontal displacement and rotation). It has sufficient vertical rigidity so that can guarantee the lesser deformation of bearing in the effect of maximum vertical load. It has fine elasticity at horizontal direction, and can adapt the horizontal displacement due to the effects of braking force, temperature, contraction of concrete, creep and load, and at the same time, it can adapt the rotation of beam end.
