Elastomeric Bearing Pads Usage and Advantages

Elastomeric Bridge Bearing Pads  Usages & Advantages

Elastomeric bridge bearing pad or laminated elastomeric bearing pad are much easier to install in bridge than compared to other types of bearing used and required nil maintence. unlike most other elastomer,elastomeric rubber pad under goes no marked stiffening at low temperature when the thermal Contraction of the bridge deck is at maximum such stiffening could be deleterious to bearing and/or structure.Correctly-designed and suitably compounded laminated neoprene rubber Bridge bearings can be confidently expected to function efficiently for at least a one and haf decade.

Elastomeric Bearing Pad

As Efficient bearing for pre-cast, Prestressed concrete or stell beams in bridge and buildings , Elastomeric Bearings Pad manufactured by us permits a smooth and uniform transfer of load from the beam to the substructure and allow beam roatation there are the bearing due to deflection of the beam under load. They further allow lateal and longitudinal movement of the beam caused by thermal forces.Have no moveable parts and thermal expansion and contraction are absorbed by the Pad's ability to give and take in shear. There is no sliding motion between pad and beam or between pad and abutment.

Elastomeric bearings shall be composed of multiple laminates of elastomeric material separated by steel reinforcing the overall size of the bearings the number of laminates and thickness of laminates are designed in accordance to the requirement of load to be transferred.Elastomeric Bearings Pad having steel plates as reinforcement shall be cast/compression moulded/vuicanized as single unit in a mould under pressure and heat.
Rubber used in the composition of Elastomeric Bearing Pad can be either natural (NR for "Natural Rubber") or synthetic, in which case the compound is generally a chloroprene polymer poly-chloroprene or CR for "Chloroprene Rubber".
