Vertical inclination of the beam should be adapted to be controlled when the price of a two-way sliding bearings to ensure that not obvious bearing shear deformation. Highway bridge bearings along the short side of the general direction of the bridge should be placed, in order to facilitate the beam end rotation, if necessary along the long side of the bridge to be placed by a two-way hinge tension and compression ring bearing, must pass the corner checking. Highway bridge bearings isotropic, without considering directional installation, just round the highway bridge bearing design to coincide with the position of the center in order to prevent the centrifugal force so that the beam transverse movement, generally on the outside set restrictions on the transverse beam stopper becomes pier. On the bridge of the installation, the use of a parallel skew quadrilateral same bevel rubber bearings, bearing at this time should be parallel to the short side of the bridge along the long side should be parallel to the centerline of the piers, along the bridge to the pier bevel angle between the centerline station should be consistent with the bearing of an acute angle, said the highway bridge bearings installed, but under normal circumstances, does not recommend the use of such bearings, bearing joints due to the use of force should be used not isotropic deformation The circular plate highway bridge support is appropriate. Highway bridge bearings and the Bay Bridge to the bridge of the use of laminated rubber bearing, should pier, station set up on both sides of the lateral stops, or measures under the steel and bearing steel is set between the stopper and other anti-shift on the beam at the end. Design shear strain shear displacement highway bridge bearing design, the maximum total thickness of shear strain inside the rubber during the maximum design earthquake shear displacement. Test pilot project designed products highway bridge bearing products should be required to conduct pilot testing, and record the test results should be made clear before the experiment design values ??for each seat, the pilot project, the cut, rubber bearing performance requirements, product performance, including highway bridge bearings, compression performance requirements, turn performance requirements, performance requirements for tensile and shear performance requirements, shear properties from the properties, ultimate performance requirements, durability requirements, highway bridge bearing anti-cyclic compression fatigue Performance requirements and counterproductive at low distortion characteristics. Compression performance requirements under the highway bridge bearing design loads should be greater than the specified maximum compressive displacement design requirements, when required compression stiffness constant double isolation bearing surfaces, should be controlled within 30%, calculate the compression stiffness, using the following formula to determine. Bidirectional ring tensile and compressive bearing hinge bearing Fuzhou _ _ finished by manufacturers to provide the best quality Rubber Co., Ltd. Hengshui Hao Tong.
