Bridge Bearings: 

This bearing is desirable for bridges. Pot bearing is economical due to simpleconstruction method and it is structurally
more compact, light, and lower in construction height and long service life. The main part of bearing are sliding plate,alloy
steel sliding surface, bearing pot, PTFE disc, pot cover, vulcanized-inpressure seal, elastomeric pad and seal against moisture.

The bearing is classified as three types: sliding guided type, free sliding bearing and fixed type.Dimensions and weights for deviating permissible concrete pressures and unusual load conditions will be calculated on request. Depending on the area
of application and country requirements pot bearings can be supplied in accordance with various standards, e.g. DIN 4141, BS5400, AASHTO, JT391, etc . 

  Bridge Bearing:The bridge bearing  at a bridge pier carrying the weight of the bridge; may be fixed or seated on.Good quality,
Low price.

           Bridge Bearing

1. Structure and performance of bridge bearing
Bridge bearing is sulfurized and stuck gether by several layers of rubber sheet and thin steel plate. It has sufficient 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; it 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 bridge support, and polytetrafluoroethylene sliding rubber support  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 is not limited; it specially
suit to bridges with medium or low load and large displancement.

bridge bearing 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, it is welcomed and widely used in bridges.

 

2.Applicability of Bridge Bearings
2.1 General  Bridge bearing 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.

2.2
Tetrafluoro rubber 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 in pushing of
continuous beam and cross sliding of T-shaped beam. The application of
rectangular and circular tetrafloro bridge  support are the same
with rectangular and circular general bridge bearing.
