PTFE bearing pad, also called PTFE bearing pads, is an important material in bridge construction. The dimpled PTFE sheet bonded to the laminated bearing pad for structure friction coefficient reduction and displacement capacity improvement. It provides a sliding surface for expansion accommodation, the elasticity of the bearing pad is high enough to suit the rotation of beam end, and also the shear deformation is efficient to cope with the horizontal of the superstructure. Here are round and rectangular two main shapes of PTFE bearing pad introduced to you.
Classification
PTFE bearing pad can be divided into roundPTFE bearing pad and rectangular PTFE bearing pad according to different shapes. They can be used in different bridge types. The rectangular PTFE bearing pad is widely used in the straight bridge or right bridge. The round PTFE bearing pad is widely used in the skew bridge, curved bridge and other bridges.
