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. When the highway bridge bearing seismic rubber bearings 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, not use. 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 close abutment with the top surface of the beam bottom and the pier, while the bearings at both ends of a beam in the same plane. Highway bridge bearings are generally provided on the bridge when using a fixed end and the movable end, the use of seat height, the horizontal displacement of the upper structure of the two ends of the beam from the same piece bearing shear deformation together to complete each shoulder in general, can also be used smaller thickness of finished rubber bearing rubber bearing as a fixed bearing, highway bridge bearing installation temperature should be controlled within the region during the period the average annual temperature or be installed for the best. If you must install at maximum or minimum temperature, in order to avoid the occurrence of excessive highway bridge bearing shear deformation. By the year when temperatures are Zaiding product from the main beam, the self-adjusted to the center position. This method is used in the railway bridge can be, and in the roads and bridges, because the number of wide bridge many, many bearing the number of roads and bridges, in general it is difficult to achieve, according to the calculation to determine the temperature at installation, with roads and bridges Supports produce a pre-displacement method to install, generally difficult to achieve. If the expected annual average temperature is not possible at the time of installation, may also be appropriate to increase the height of the seat easy way to choose the design of highway bridges grid bearing of rubber bearings, which is extremely low when asked to install, make sure the maximum upper structure When the amount of displacement due to be considered high end pre-shear deformation temperature impact need to increase the amount of displacement into account, consider options to increase the total thickness of the rubber layer of rubber bearings needed.
