Installation and construction of roads and bridges laminated rubber bearing installation and construction of roads and bridges in the laminated rubber bearing highway bridge construction project is the most common and the laminated rubber bearing elements and installation considerations for the construction and installation of the same type of support reference seat. In bridge construction, the construction and installation of rubber bearings are often considered the construction unit construction is relatively simple and not take it seriously, to use the bridge brings risks. In fact, in an important position rubber bearing bridge structure connecting the upper and lower points, is the vehicle load and load transfer to the structure of the upper part of the lower structure of the intermediate link, it directly affects the safety of the reliability and durability of the bridge structure. Therefore, in addition to ensuring the quality of rubber bearings meet the technical standards, the proper construction and installation of a rubber bearing the key to the success of the application. For laminated rubber bearing laminated rubber bearing structure type is divided into ordinary laminated rubber bearings and tetrafluoroethylene laminated rubber bearing from the structure. Laminated rubber bearing is divided into rectangular and circular shapes from. Ordinary laminated rubber bearing more suitable for long span of less than 30m, the smaller the amount of displacement of the bridge. Different plane shapes for different bridge structures: orthogonal rectangular bridge abutment; curved bridge, skew bridge and bridge pier with a circular cylindrical bearing; skew bridge can support (it uses bevel (parallelogram) the skew angle of the same acute angle with the beam), but this is being replaced by circular bearing seat. Tetrafluoroethylene laminated rubber bearing more suitable for long-span, multi-span continuous, large displacement of the simply supported beam continuous slab bridges and other structures. It is also used as a continuous beam push and T-beam traversing the slider. Rectangular, circular tetrafluoroethylene laminated rubber bearing applications were identical with ordinary laminated rubber bearings. Support for the use of bridge bearing pad stone set in order to ensure the construction quality rubber bearings, as well as installation, adjustment, and replacement bearings were observed convenience; whether it is the use of pre-cast beam or girder construction method, no matter what type of installation The laminated rubber bearing, bearing pads set in stone pier top is necessary. During the construction of stone bearing pad should note a few issues: ⑴, plane size stone bearing pad size should be able to withstand the load of the upper structure is appropriate, generally the length and width should be greater than about 10cm rubber bearings. Pad stone should be greater than the height of 6cm, in order to ensure the beam bottom to the top surface of the pier there is enough space height, to place the jack, bearing exchange for use. ⑵, should be laid steel mesh, should be connected to the vertical steel reinforcement inside the inner bearing pad stone piers. Cast stone concrete pad should not be less than C30 label number or not less than the design label, the top surface of the concrete pad stone should be pre-calibrated with a spirit level, and strive to smooth and not smooth. ⑶ bearing pad stone top elevation to be accurate and consistent. In particular, the top surface of the support pad stone two or four beams a bearing should be in the same plane, so as not to bias generating, the initial shear stress and unevenness phenomenon.
