Highway bridge bearings, hybrid bearing, except with rubber bearings to adapt the following main features, due to the rotation function is separated from the rubber bearings, you can further expand the range of adaptation rotation compared with rubber bearings, while increasing After the rubber closures, highway bridge bearing not only has the ability to pressure the vertical load, and adapt to the requirements of the rotation function, vertical load bearing function, horizontal displacement adaptation function, elastic support functions. Highway bridge bearings sealed rubber cap structure due to the deformation of the rotation to absorb deformation of the bridge, so do not pass highway bridge bearing province affect rotation. DOF structure significantly increased costs have also been reduced. With a vertical load bearing function and use the rotation function. Construction of the highway bridge bearings, first of all, Bonham product quality is an important prerequisite for the installation and maintenance of the entire seat, so the factory highway bridge bearing supports, coping quality of each batch of products tested before delivery. Before the factory by factory after factory inspection and quality inspection departments to confirm eligibility seismic slip bearing, should be shipped with product quality standards together with supporting documents bearing specifications and other relevant information in order to use the unit for acceptance and sampling. 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. 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, you should check the product certificate regarding technical performance, especially in highway bridge bearing on whether the product should check the manufacturer's trademark and a permanent marker, which do not meet the design requirements tensile ball bearings shall not be used. After the highway bridge bearing installation, if found individual bearing separation, uneven tensile stress ball bearings, bearing large initial shear deformation occurs and serious side bearing abnormal bulge 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.
