Product Description

Elastomeric Bearingare made of multiple layers of rubber sandwiched with and bound to thin steel sheets, and then through vulcanization.

    Its vertical rigidity is sufficient to bear the perpendicular load and to shift the pressure reliably from the superstructure to the piers.

    Its elasticity is high enough to suit the rotation of the beam end. Its shear deformation is sufficient to cope with the horizontal displacement of the superstructure.

    
Functions
 

• Load transfer: Rubber bearings can effectively transfer the load of the upper structure of the bridge to the piers or abutments.

• Adaptive deformation: Rubber bearings have good elasticity and significant shear deformation ability, which can adapt to the deformation of bridges caused by factors such as temperature changes, concrete shrinkage, and creep.

• Seismic isolation and damping: Rubber bearings can reduce the impact of natural disasters such as earthquakes on bridge structures, and some specially designed rubber bearings also have better seismic isolation performance.

• Adjusting displacement: Rubber bearings can adjust the relative displacement between the upper and lower structures of the bridge to a certain extent, ensuring the stability and safety of the structure.

• Damping energy dissipation: Some rubber bearings are designed with damping mechanisms, which can reduce structural vibration by dissipating energy during earthquakes and other situations.

    In summary, rubber bearings play a crucial role in bridge construction. They can not only effectively transmit loads, but also adapt and adjust various deformations, improve the seismic isolation and damping performance of bridges, and ensure the safety and stability of bridge structures.
