T-girder bottom width than the width of hours of treatment bearing ball bearing earthquake, this phenomenon is generally avoided, if the event should be between a highway bridge support beam at the end of the beam and on 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, 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, product certificate regarding technical performance steel sliding bearing, especially highway bridge bearings should be checked whether the product manufacturer's trademark and a permanent marker, which do not meet the design requirements should be checked 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 replacement, adjustment method will generally be from the top end of the beam using the jack, up 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. Various damping bearings have similar functions and role of the highway bridge bearing the classification listed, ie they can be supported by the dead load and live load on the bridge 承桥梁 structure in the vertical direction, in the horizontal direction, there are better seismic bearing steel flexible to meet the larger displacement, the highway bridge bearing long period of vibration of the bridge structure, while taking advantage of absorbing vibration energy dissipation, thereby improving the performance of the bridge structure, to reduce earthquake The purpose of the role of power, for a variety of highway bridge bearing works, highway bridge bearings is based on the general rubber bearings. At its center or pushed around with one or more of lead can absorb the energy dissipation combination of a pin bearing damping bearings, highway bridge bearings have consumed when loading Descriptions of deformation greater than public uninstall Metal release of deformation work, so there is some deformation under load is absorbed by the lead pin. And then converted into heat energy dissipated into the atmosphere, so as to achieve the purpose of absorbing vibration energy dissipation, the use of lead as a highway bridge bearing pin is metallic lead reason after cold deformation, can be crystallized at normal temperature.
