Gallop bridge with you to understand the structure and properties of Gallop bridge laminated rubber bearing laminated rubber bearing production of multilayer thin steel sheet and vulcanized rubber, bonded, it has enough vertical stiffness, can the upper reaction force reliable delivery structure to the pier, with good flexibility to adapt to the beam end rotation of 200 × 200 × 20 damping pads, there are large shear deformation bridge neoprene cushioning pad to meet the horizontal displacement of the upper structure. Physical performance specifications Neoprene (for -25 ℃ ~ 60 ℃) Hardness (IRHD) 60 ± 5 Tensile strength (MPa) ≥17 Elongation at break (%) ≥400 brittleness temperature (℃) ≤-40 constant compression set (70 ℃ X24h) (%) ≤15 Ozone aging (test conditions, 20% elongation, 40 ℃ x 96h) 100pphm 1, plate bearing Products highway bridge laminated rubber bearing with respect to the other constituent bearing structure is relatively simple, it is placed in a thin sheet steel and rubber tire tool in After curing, bonded, as bearing plate has sufficient vertical stiffness which can be reliably transfer stress to the upper part of the bridge piers ; ensure good stability neoprene rubber damping pads, bearing plate has very good flexibility, can produce very good shock effect, can reduce the effect of dynamic load on the upper structure and pier. One end of the bridge can be adapted to rotate; strong shear deformation ability of this product, enough to adapt to the level of the upper structure of the temperature change displacement. Since the laminated rubber bearing with a horizontal cut isotropic, we can deliver good upper structure and more deformed. In turn, the bridge of the use to advantage. The products in addition to the functions of ordinary damping pad holder, but also has the role of the force when the beam end by a spherical surface of the rubber layer to adjust the position of the center of the force, the force gradually spread to the circular laminated rubber bearing steel and rubber layer, so bearing force uniform, especially for places skew bridge, overpass bridge slope. Laminated rubber bearing according to the shape can be divided into: a spherical cap bearing circle, rectangle bearing, circular plate bearing. 2, plate bearing applicable General ordinary laminated rubber bearing bridge applies span of less than 30m, for displacement of the smaller bridges. Common carriage is one of the more traditional bearings, widely used in highway bridge supports, due to its excellent shear performance and installation convenience features widely recommended, but aging is a plate bearing the disadvantages of having a . Different shape configurations for different bridge structure, orthogonal rectangle bearing bridges, curved bridge, skew bridge and the bridge pier with circular cylindrical bearings. Movable bearing is tetrafluoroethylene laminated rubber bearing, because In ordinary plate bearing foundation added a layer of PTFE plate derives its name, is generally applicable large span, multi-span continuous, continuous panels using simple bearing structure with a large amount of displacement of the bridge. Its value is very broad, but also can be used as continuous beams and T-beams pushing sliding the slider. Rubber bearing laminated rubber bearing is the most common one, is making the most simple kind.
