Rubber bearing Specification:
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 .
General plate rubber bearing :The support at a bridge pier carrying the weight of the bridge; may be fixed or seated on.Good quality,Low price.
General plate rubber bearing :
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.
Applicability of General plate rubber bearing:
2.1 General Bridge support 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 support 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 General plate rubber bearing are the same with rectangular and circular General plate rubber bearing.
