Plate rubber bearing
Bridge plate rubber bearing main function is to bridge the upper structure of the reaction force to pass to the pier and abutment to adapt to the beam end rotation and through the rubber bearing shear deformation to adapt to the superstructure of the free deformation (horizontal displacement and rotation). According to these requirements, the plate rubber bearings should be designed to have sufficient stiffness in the vertical direction, so as to ensure the maximum vertical load, the bearing is less flexible deformation; horizontal direction should have a certain flexibility to adapt to the beam Due to the braking force, temperature, concrete shrinkage, creep and load caused by the horizontal displacement; at the same time to adapt to the rotation of the beam.
