Press bearing materials and adapt to temperature division (a) normal-type laminated rubber bearing, using chloroprene rubber production, which adapt to changes in the temperature range may not be used in place of natural rubber neoprene elastic damping steel ball bearings, are not allowed incorporation of natural rubber in the chloroprene rubber. (2) cold-type laminated rubber bearings: Should the use of natural rubber (NR) production, which adapt to a wide range of temperature changes. Fulcrum rebate bridge superstructure is 150 ~ 8000KN bridges, and more generally the use of laminated rubber bearings. Ordinary laminated rubber bearings for smaller and smaller displacement span bridge, a different plane shapes for different bridge span structure, namely orthogonal rectangular bearing bridge, curved bridge, skew bridge pier bridge should use a circular cylinder stand. PTFE slide rubber bearing suitable for large-span bridges multi-span continuous unidirectional sliding steel ball bearing type DX, Charpy and continuous plate structures such as large displacement of the beam, it can be used as a continuous beam Ding push and T-beam traversing the slider used and so on. Rectangular and circular PTFE slide rubber bearing applications are the same as ordinary rectangular and circular laminated rubber bearing. The main function of the spherical bearing reaction force is to bridge superstructure reliably transmitted to the pier, and also to adapt to the bridge structure displacements and rotations of deformation, based on these performance requirements, laminated rubber bearings should be designed to have in the vertical direction sufficient stiffness to ensure that the maximum vertical loads bearing a certain compression deformation, the general provisions of bearing the greatest compression and shall not exceed 15% of the total thickness of the rubber, laminated rubber bearings should be in the direction of the horizontal force has a certain flexibility to adapt due to the vehicle braking force, temperature, creep and shrinkage of concrete and live loads fixed horizontal displacement of the beam steel ball bearing type GD, while bearing thickness should also be able to adapt the beam angle needs. Bridges laminated rubber bearings can be designed to become a fixed period, and the other end to the activities of the holder, it can be designed as part of the fixed end and the movable end of the bearing. Fixed bearing generally relatively thin thickness, to meet the vertical support beam reaction force and the end of the beam can rotate freely requirements. Horizontal displacement of the beam is mainly composed of a rubber shear deformation of the movable carriage to complete, depending on the height of the size of the amount of horizontal displacement. Fixed at both ends regardless of when the activities end bearing. Both the same thickness, horizontal displacement completed simultaneously by two bearings, each bear half. Meanwhile steel ball bearings, all laminated rubber bearing, at the minimum vertical loads should ensure bearing itself without any slippage imagination.
