Jun 2015 vertical bridge rubber bearing rubber bearing model 13383388737, rubber bearing basin principle structure is placed in a sealed steel pot rubber block, in the case of three of the force, the force generated while the anti-bear bridge load, while the elastic rubber satisfy the beam end rotation, by welding a stainless steel plate in attendance board polytetrafluoroethylene freedom slip, completion of the horizontal displacement of the upper portion of the bridge structure. The series has a reasonable structure, large carrying capacity, small deformation, horizontal displacement capacity, flexible rotation, and have good cushioning properties, is the best seat continuous bridge construction, rubber bearing basin and has a light weight, compact, simple structure, low building height, easy manufacturing, save steel, reduce the cost, etc., is an ideal fit for large bearings used in bridge collapse. Commonly used GPZ, GPZ (Ⅱ), GPZ (KZ) three categories. GPZ (II) series bearing the current carrying capacity of 31 levels, bearing capacity 0.8MN-60MN, to meet the needs of large bridges built. Bearing rubber bearing basin classification based on the application range can be divided into three categories: highway bridge rubber bearing basin, the railway bridge rubber bearing basin and basin-type rubber bearing derivatives. Commonly used road rubber bearing basin models: GPZ pot rubber rubber bearings and GPZ (Ⅱ) basin rubber rubber bearing (based GT391-1999), GPZ (KZ) rubber bearing basin, and several other series. Common rail rubber bearing basin has TPZ-I railway pot rubber bearing, TPZ standard railway pot rubber bearing, designed 8156 bridge railway bridge support. Derivatives of types of rubber bearing basin of many, such QPZ pot rubber rubber bearings, KPZ series rubber bearing basin, elastic damping steel ball bearings, self-leveling and other rubber bearing basin. Each category can be divided according to the displacement in the form of a fixed (GD), a one-way activity (DX) and bidirectional activity (SX) three.
