Pot type rubber bearing

The basin-type rubber bearing mainly uses the elastic rubber enclosed in the steel pelvis, which has the characteristics of incompressible fluid volume under the three-way stress state, and reliably transmits the reaction force of the bridge superstructure to the abutment, and realizes the construction of the bridge. The rotation of the beam end depends on the free sliding between the PTFE plate and the stainless steel sliding plate to adapt to the horizontal displacement and rotation of the bridge superstructure due to factors such as load, temperature change, concrete creep and shrinkage, etc., so as to ensure the bridge safety.
