Rubber bearing basin due to the vertical force children to do the radius of the spherical bearing and spherical difference made very small, can withstand greater reaction force, but in the rotation will be in contact with the sliding surface, then often in the sphere of contact Problems arise at the card at the same time this pot rubber bearing corrosion problems also exist relatively large. Furthermore, because such rubber bearing basin in the horizontal direction does not allow any stretch of the formula can be used as a fixed support seat use, attention should therefore be used in a wide bridge and caused adequately studied. Rubber bearing basin between the plate and the lower bearing plate Theravada know cylindrical hinge structure, usually unidirectional turning type of fixed bearing. According hinge support is divided into two kinds of support type and shear. While focusing on rubber bearing basin can be considered as the arch bridge, pier foundation and rigid frame viaduct pier hinge use, but be aware of this when the transverse bearing structure to a structure not allowed. When designing rubber bearing basin, we must fully understand the entire bridge abutment in the role, rubber bearing basin is important to connect the upper part and the lower part of the structure of the bridge structure, it must have the following main bridge support role and functional requirements. (1) must be able to support lateral loads from dead loads, live loads and other vertical seismic and wind loads and passing the upper structure, and secure courier to the substructure (piers, Taiwan). (2) rubber bearing basin horizontal displacement of the upper structure must be adapted by the live load and temperature changes and produced by the deflection angle displacement fulcrum. (3) In order to improve the seismic performance of the entire bridge during an earthquake, damping and isolation bearings should have new energy, that is, under seismic and wind (wind station) role, with great changes to adapt to the instantaneous position of the effect. (4) rubber bearing basin with the installation, replacement and maintenance convenience. (5) rubber bearing basin has a buffering effect in the vehicle role. A pot rubber bearing reaction force to bear bearing longitudinal length rubber bearing basin, the basic allowable stress of steel gusset plates and the total thickness of the adapter plate products seismic reaction pot bearings, when the configuration shown, equal to two and the thickness of the gusset plate and two splice plate. Rubber bearing basin bottom hem hem area placed rollers should meet the needs of top hem pot rubber surface height to the underside of branches into every board should not generally be less than one seat plate in a direction along the length of the half-bridge stress should include checking the hem flexural stress, shear stress and the upper curved hem bearing pressure in two parts. When rubber bearing basin flexure and shear stresses checking hem should be considered after the pot rubber bearing eccentric shaft position moving impact on the hem, so the design should first determine the offset of the soul curse pot bearings, when the rubber bearing basin in the middle position type, hem centerline coincides with the centerline of the seat plate, this time the reaction force damping pot bearings, roller shaft is in the middle position, that is Activities vertical unidirectional reaction force pot bearings, quiet distance equal to zero at this time, when the upper rubber bearing basin moved to the right, the relative position of the reaction force is relatively stable damping pot bearings _ Hao-engineering rubber ( Certified) _ pot bearings provided by the Engineering Rubber Co., Ltd.
