High quality Bridge elastomeric bearings

Elastomeric Laminated Rubber Bridge Bearings:

1. Structure and performance of Elastomeri Laminated Bearings

Elastomeric Laminated Bearings 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 Elastomeric Laminated Bearings, and polytetrafluoroethylene sliding Elastomeric Laminated Bearing is formed. Besides vertical rigidity and
elasticdeformation, 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.

Elastomeric Laminated 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, it is welcomed and widely used in bridges.

2.Applicability of Elastomeric Laminated Bridge Bearing:

2.1 General Elastomeric Laminated 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 Elastomeric Laminated 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 Elastomeric Laminated Bearings are the same
with rectangular and circular general Elastomeric Laminated Bearingrately.
