Bridge rubber bearings are bonded multilayer thin steel sheet of the multilayer rubber vulcanization a common rubber bearing product that has sufficient vertical stiffness, the ability to reliably transmit a reaction force to the holder of the superstructure pier, bearing with good flexibility to respond to the beam end rotation bridges; there are large shear deformation capacity to meet the horizontal displacement of the upper structure. NOTE: The installation instructions bridge support bridge support physical and mechanical properties of rubber bridge bearings About our company's bridge bearing products, including: ordinary plate bearing, tetrafluoroethylene plate bearing, spherical cap rubber support Block three products. Bridge bearings are bonded by a common multi-layer and multi-layer sheet steel vulcanized rubber sheet rubber bearing a common product that has sufficient vertical stiffness, the ability to reliably transmit a reaction force to the holder of the superstructure pier, rubber bearings have good flexibility to respond to the beam end rotation bridges; there are large shear deformation capacity to meet the horizontal displacement of the upper structure. When in the normal sticky rubber bearing surface complex layer 1.5mm-3mm thick polytetrafluoroethylene material can be made into a Teflon slip rubber bearings in addition to its vertical stiffness and elastic deformation, can withstand vertical Loads and adapt to the beam end rotation, due to the low friction coefficient of the PTFE plate, beam end can slide freely PTFE plate surface, horizontal displacement is not restricted, especially suitable for medium and small loads, use a large amount of displacement of the bridge I produced the bridge bearing products are not only advanced technology, excellent performance, but also has a simple structure, low cost, easy to replace without conservation buffer isolation, low building height. Thus the bridge support popular, widely used . Bridge bearing plate classification and representation 1, according to the structure type of bridge rubber bearings are classified as follows: General --- spherical cap rubber bearings circular rubber bearing (TCYB series); rectangle ordinary rubber bearing (GJZ series); Round ordinary rubber bearing (GYZ series). ---- Round tetrafluoroethylene PTFE rubber bearing rubber bearing (GYZF4 series); rectangular tetrafluoroethylene rubber bearing (GJZF4 series) spherical cap rubber bearings tetrafluoroethylene (TCYBF4 series). 2, rubber bearing according to types of plastic Temperature categorized as follows: a, neoprene: Temperature + 60 ℃ ∽-25 ℃ b, natural rubber: Temperature + 60 ℃ ∽-40 ℃ c, EPDM: Temperature + 60 ℃ ∽-45 ℃
