Description of Rubber Bearings
Rubber Bearings generally consists or interleaving layers of rubber bonded sandwich fashion to steel plates. The
whole unit is covered with rubber to afford weather protection.A bridge basically consists of bridge deck supported by piers.
In order to avoid over stressing and damage by movements of vehicle and loading to the piers, Rubber Bearings are used to accommodate these movements so as to reduce the reaction forces and bending movement to
within the safety limits of structure. Natural Rubber is an ideal engineering material for bridge bearings as it is highly elastic
and sufficiently soft to accommodate these movements without transmitting harmful stress and also it can absorb and isolate
energies from impacts and vibrations.
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 bearing is welcomed and widely used in bridges.
Aplication of Rubber Bearings
1. Rubber Bearings suits to bridges with span less than 30m and small displacement. Different flat shape suits to different bridge span structures: orthogonal bridges adopt rectangular bearing; curvilinear bridges, obique crossing bridges and cylindrical pier bridges adopt circular bearing.
2. Rubber Bearings 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 in pushing of continuous beam and cross sliding of T-shaped beam. The application of rectangular and circular tetrafloro Rubber Bearings are the same with rectangular and circular general Bridge Bearing ,separately.
Classification and representation methods of Rubber Bearings
(1) Classification as shapes of Rubber Bearings
a.Rectangular rubber bearings
b.Circular rubber bearings
(2) Classification as applicable temperature of adhesive varieties of rubber bearings
a.Neoprene bearing(applicable temperature -25~60°C)
b.NR bearing (applicable temperature -35~60°C)
c.EPDM bearing (applicable temperature -40~60°C )
(3) Classification as structure style of rubber bearing
a.General plate type neoprener bearing
b.Tetrafluoro sliding plate type neoprene bearing
The operating principle of Rubber Bearings
The main function of rubber 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.
