Bridge Bearing Pad provide a uniform transfer of load from beam to substructure.They permit beam rotation at the bearing point due to deflection or misalignment. They absorb vibration and prevent sound transfer, while reducing the destructive action of vibration between movable and stationary structural members.
Bridge Bearing Pad
They also provide for movement caused by normal expansion and contraction. Neoprene Bearing Pads are used extensively in bridge structures and prestressed and precast concrete buildings. Also used in industrial machinery and heavy equipment applications.
Types of elastomeric bearing pads
Laminated bearings – an elastomeric bearing containing steel laminates bonded to rubber
Plain pad bearing – a plain rubber pad containing no steel plates
Strip bearing – a plain pad bearing for which the length is much greater than the width (> 10 times)
Pot bearing – a bearing consisting essentially of a block of solid rubber enclosed between a metal piston and metal cylinder
Preparation of rubber compound according to specification required
