PTFE Bridge Bearings
PTFE Bridge Bearing is made of multilayer natural rubber and sheet steel after inlay, conglutinate, vulcanization.
PTFE Bridge Bearing has enough vertical stiffness to support vertical load, and it could deliver the pressure of
super structure to abutment.
Features of PTFE Bridge Bearings:
1. Our PTFE Bridge Bearing has good elasticity to adapt to turning of beam end.
2. Our PTFE Bridge Bearing has bigger shearing deformation to content horizontal displacement of superstructure.
3. Our PTFE Bridge Bearing has simple structure, easy installation, saving steels, low price, easy and convenient
conservation and change and so on.
bearing of bridge Divided into the following according to bearing structural type:
(a) Common PTFE Bridge Bearings is divided into rectangular PTFE Bridge Bearings (code name GJZ) and circular PTFE Bridge Bearings (code name GYZ);
(b) PTFE Bridge Bearing is divided into rectangular PTFE Bridge Bearings (code name GJZF4) and circular PTFE Bridge Bearings (code name GYZF4).
bearing of bridge Divided into the following according to bearing material and applicable temperature:
(a) Normal temperature PTFE Bridge Bearings: It should be made of chloroprene rubber (CR), applicable temperature -25ºC~60ºC. Natural rubber cannot replace chloroprene rubber, and natural rubber cannot be mixed in chloroprene rubber.
(b) Cold-resistant PTFE Bridge Bearings: It should be made of natural rubber (NR), applicable temperature -40ºC~60ºC.
Structure of PTFE Bridge Bearings:
PTFE Bridge Bearing is made of multiple layers of rubber sandwiched with and bound to thin steel sheets, and then through vulcanization. The vertical rigidity of the PTFE Bridge Bearing is sufficient to bear the perpendicular load and to shift the pressure reliably from the superstructure to the piers. The elasticity of the PTFE Bridge Bearings is high enough to suit the rotation of the beam end. The shear deformation of the PTFE Bridge Bearing is sufficient to cope with the horizontal displacement of the superstructure.
