T-beam beam width than the bottom bearing width hours of treatment, this phenomenon is generally avoided, if the event should be at the end of the highway bridge support beam and the beam at the end with a ring yang between the adhesive resin mortar ratio bearing slightly reinforced concrete pad or thick steel plate as a transition, in order to avoid highway bridge supports partial overload, stress concentration. Highway bridge bearings installed after the earthquake off the ball bearing beams, 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, 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 hinge bearing manufacturer, larger initial shear deformation and bearing a serious side bearing abnormal bulge occurs when the local void, should be timely adjustment and replacement, adjustment method will generally use the 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. Highway bridge bearing functional requirements for reduced spherical bearing on seismic bridge, bridge rubber isolator bearings should have regular basic features, such as roads and bridges weight and live load bearing structures to absorb the upper pick oh telescopic displacement stocks, rotation and deflection under normal environmental conditions and curing conditions holder, able to work properly during the design life of the highway bridge bearings, abnormal environmental conditions, the highway bridge bearings should take emergency measures to zero. Although rubber bearings designed to search for Che Kung Hu cut, roads and bridges stand alone nor can it be used as a long-term bear continuous shear. If it is used to design to withstand tension, be especially careful. Chosen limit, highway bridge bearings should get a structural engineer and manufacturer of dual recognition. Design and manufacturer of pressure forced the dual recognition. Design stress and shear deformation is determined by the following formula. Design stress, the design pressure, effectively flat ian and a maximum design stress, highway bridge bearing the maximum design pressure and effective area of ??overlap between the highway bridge bearings top and bottom surfaces.
