Buy rubber bearing ordinary rectangular-wide rubber Hengshui preferred to focus on productivity, quality first

Products into a rectangle (round) laminated rubber bearing (a) Performance: The product consists of a multi-layer rubber sheet with a thin steel inlay, bonding repression and hair. There is sufficient vertical stiffness to the vertical load bearing, the upper structure of the reaction force can be reliably transmitted to the pier, with good flexibility to adapt to the beam end rotation; there are large shear deformation of the upper structure to meet horizontal displacement. (B) Features: This product has been widely used in bridge construction, hydropower projects, housing seismic facilities, compared with the original use of steel bearings, has a simple structure, easy installation; save steel, low prices; simple maintenance, easy to replace etc., and the low height of the product architecture, good design and reduce the cost of the bridge; there is good isolation effect, can reduce the impact of the role of live load and seismic forces on the building. Product Selection a: View laminated rubber bearing installation and construction drawings, the main attention to the specifications of laminated rubber bearing type, height, carrying capacity and other major technical parameters. Also note tetrafluoroethylene skateboard rubber bearing embedded steel dimensions and mounting position and orientation; b: the choice of laminated rubber bearings, the maximum carrying capacity of the bridge bearing fulcrum reaction force should coincide, their tolerance range appropriate for the ± 10%; c: For curved, sloping, oblique, wide bridges, should use circular laminated rubber bearing. Road and Bridge are not allowed to use the ball-shaped crown or slope of rubber bearings; d: When the bridge longitudinal gradient of not more than 1%, laminated rubber bearings can be set directly on the pier, but it should be required to consider the impact of longitudinal thickness. When the longitudinal slope greater than 1%, should be used embedded steel (plus wedge plate), concrete pads (pads rocks slope) or other measures to end the beam leveling, to ensure bearing flat position. Laminated rubber bearings should JTG D62 relevant provisions of checking and checking before being used to meet the requirements. e: GJZF4, GYZF4 type PTFE slide rubber bearings should be installed horizontally. And should be set down plates, between PTFE slide coated with a stainless steel plate should be put 5201-2 lubricating grease, dust cover must be set after installation; PTFE slide bearing holder shall not be set in the underside, and PTFE slide contact with stainless steel can not be set on the bridge piers, stone table mat.
