PTFE plate sliding bridge rubber bearing laminated rubber bearing bridge rubber bearing laminated rubber bearing sliding PTFE sheet has good flexibility and vertical stiffness, No. 1366 3286655 can rely on shear properties of the rubber sheet to adapt the beam end rotation, there is relatively large shear deformation capacity, can well adapt to the upper structure of the horizontal force is composed of thin layers of steel and vulcanized rubber sheet, bonded, and has a sufficiently large vertical stiffness. PTFE plate slide horizontally laminated rubber bearings have a certain flexibility to adapt the beam due to the braking force, temperature, shrinkage and creep of concrete and horizontal displacement caused by loads. ???? Bridge rubber bearing laminated rubber bearing sliding PTFE plate can also be called a sliding laminated rubber bearing, in fact, on the basis of the above plus laminated rubber bearing a layer of PTFE plate to meet the beam slide needs, PTFE sheet thickness displacement is generally 1.5-3mm, PTFE sheet laminated rubber bearing model: GJZF4 highway bridge PTFE plate rectangular rubber plate bearing, GYZF4 PTFE plate circular highway bridge laminated rubber bearing, PTFE sheet laminated rubber bearing has a low coefficient of friction, can fully meet the horizontal displacement of the upper member, more suitable for large displacement of the bridge, PTFE plate movable bearing structure is simple, inexpensive and widely available. PTFE plate sliding bridge rubber bearing laminated rubber bearing shear deformation of the rubber sheet is not required to achieve the bearing telescopic displacement, aging and reduced bearing wear, for tetrafluoroethylene laminated rubber bearings for large span, multi-span continuous, large displacement of the bridge simply supported beam structure consecutive panels. bridge bearing replacement is relatively easy, the replacement process is simple and fast. It is also used as a continuous beam push and T-beams traversing the slider. PTFE plate sliding bridge rubber bearing laminated 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 ℃ rubber seal, water stop, polysulfide sealant, polysulfide sealant, plastic water stop, rubber bearings, cement gray two-component poly sulfur sealant, two-component polysulfide sealant (glue), polysulfide sealant (paste), water swelling water stop, rubber water stop, externally bonded water stop, back posts water stop, buried only with water, cement colored construction sealant, water expansion of the seal, GB sealing strip
