Reason and Advantage of Using Neoprene Elastomeric Bearings
Why Use Neoprene Elastomeric Bearings
Neoprene bridge bearings - plain or laminated - elastomeric bearings are much easier to install in a bridge than compared to other types of bearing used and require nil maintenance. Unlike most other elastomer, Neoprene rubber 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 decade
As efficient bearing plates for pre-cast, pre-stressed concrete or steel beams in bridges and buildings, Neoprene Pads - plain and laminated - manufactured by us permits a smooth and uniform transfer of load from the beam to the substructure and allow beam rotation at the bearing due to deflect ion of the beam under load. They further allow lateral and longitudinal movement of the beam caused by thermal forces. Neoprene Pads have no movable 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.
