T-beam beam width than the bottom bearing width hours of treatment, this phenomenon is generally avoided, if the elastic support bearings Once there, you should end on the highway bridge support beam and the beam between the bottom with a ring yang adhesive resin mortar slightly larger than the bearing thick steel reinforced concrete pad or as a transition, in order to avoid overloading the highway bridge supports partial, stress concentration. After falling girder highway bridge bearing installation, under normal circumstances seismic spherical bearing, its top surface should be level. But simply supported beam prestressed its top surface can luew seat tilted back, the top surface of the non-prestressed bearing shear may be slightly tilted forward. Note highway bridge bearings installed. Highway bridge support before installation, you should check the product certificate regarding technical performance, especially if the highway bridge bearing the manufacturer's trademark and permanently marked on the product should be checked, such as when the design does not meet the requirements, shall not be used. After the highway bridge bearing installation, if found individual bearing separation, uneven force, there is a greater initial bearing shear deformation and serious side bearing abnormal bulge local void, should be adjusted in a timely and Replace the bearings, adjust the method generally adopted jack from the top end of the beam, and down the highway bridge bearings coated with a layer of cement mortar or epoxy mortar. Beam off again, bearing the weight up and down the surface force in the beam should be parallel to each other and the same beam bottom and the top surface of the piers close, while the bearings at both ends of a beam in the same plane. Combined highway bridge bearing damping capacity and draw bridge damping demand for damping highway bridge design bridge bearings used in the selection system class diagram, this is only for the principles and methods of highway bridge highway bridge bearings standardization proposed direction but it is an issue to be further studied. Should and should pay attention to the issue of the LRB. Highway bridge bearings and lead-free rubber bearing compared to driving to the initial elastic stiffness. It is precisely because the initial elastic stiffness of large highway bridge bearings, so it can do than highway bridge bearing pin lead-free number, and in the earthquake LRB stiffness decreases rapidly building steel support Block, the bridge can be extended to some extent the natural cycle, when the earthquake LRB can play performance, even a very good energy absorption system, and can change the phase relationship between the top and the pier, change during an earthquake maximum energy value of the structure, which can reduce the maximum impact value structure. _ Taizhou bearing stiffness elastic support provided by Hengshui HaoTong _13833855982 Rubber Company.
