Laminated Elastomeric Bridge Bearings

Laminated elastomeric bearings consist of natural rubber layers separated by steel plates.

Laminated elastomeric bridge bearings. Standard un reinforced bearing pads and strips. The result is a comprehensive catalogue of elastomeric bearings covering. Not only do these embedded steel plates limit excessive expansions but also increase transversal longitudinal and compressive strength as well as rotation capability comparing with plain elastomeric. These items are then vulcanised to create a compact maintenance free bearing.

The primary function of elastomeric bearing pads is to provide a connection to control the interactions of loading and movements between parts of a structure usually between superstructure and substructure. Bridge bearing as connection component can provide a resting surface between bridge and bridge piers. Elastomeric bearings can absorb horizontal movements in every direction and rotational movements around every axis through elastic layers deformation. Laminated elastomeric bearings support simultaneous loads and deformation in any direction.

Steel plates are bonded to the rubber through a vulcanization process and have the main scope to increase the resistance of the bearings to vertical loads. Adding a layer of ptfe on the surface of steel laminated elastomeric bearing the. Laminated elastomeric bearing features reinforced steel plates that are sandwiched between layers of rubber through vulcanization and molding manufacturing process to form a homogeneous unit. For applications where horizontal displacements exceed 2 inches 50mm sliding elastomeric bearing assemblies may provide an economical solution.

And the purpose of bridge bearing is to transfer forces from the superstructure to the substructure or reduce the ground vibration to the superstructure. A laminated elastomeric bearing is an elastomeric rubber block reinforced with steel plates vulcanised when built. High capacity steel plate laminated bearings also known as elastomeric bearings laminated bearings or elastomeric laminated bearings granor has supplied specially designed laminated bearings up to 800 x 800 x 321 mm. The steel plates are fully embedded in the elastomer so that they are protected against corrosion.

Elastomeric laminated bearings elastomeric laminated bearings elb s are made from high purity elastomers which encapsulate layered internal steel reinforcing plates. Laminated elastomeric bearing pad one type of reinforced elastomeric bearings is made of multi layer rubber and reinforced with steel plate through sulfuration and adhesion compared with non reinforced elastomeric bearing it has sufficient vertical rigidity which can reliably transfer the concentrated down loads and impact loads of the superstructure to both ends of the pier. Designed for use in bridge and building construction under pre cast concrete beams steel beam supports and other support points. This bearing is the connection between a structure and its support and should make the following possible through elastic deformation.
