High-bearing-capacity composite bridge rubber support
The invention relates to a high-bearing-capacity composite bridge rubber support which comprises an upper sealing plate, protective glue, a thin steel plate I, a thin steel plate II, a rubber layer I, a rubber layer II, a lower sealing plate and a flat plate friction part. A flat plate friction part composed of a stainless steel plate, a polymer sliding plate and an annular foaming polymer is compounded in the rubber support of a laminated structure. In the horizontal direction, the deformation of the flat plate friction part is consistent with the direction of the bridge, the relative deformation of the bridge is converted into the shear deformation of the support and the horizontal displacement of the flat plate friction part, and the support and the flat plate friction part bear the vertical load of the bridge together in the vertical direction. The multi-stage energy-dissipation bridge is high in vertical bearing capacity, has the self-resetting capacity, is clear and definite in principle, simple in structure, stable in performance, convenient to produce, capable of achieving multi-stage energy dissipation, capable of coping with multi-stage earthquakes while meeting the requirement for normal use of the bridge, high in damage resistance and wide in application prospect.
本发明涉及一种高承载复合桥梁橡胶支座，包括上封板、保护胶、薄钢板Ⅰ、薄钢板Ⅱ、橡胶层Ⅰ、橡胶层Ⅱ、下封板、平板摩擦部；在叠层结构的橡胶支座内部复合由不锈钢板、聚合物滑动板、环状发泡聚合物组成的平板摩擦部；在水平方向上，平板摩擦部的变形与桥梁方向一致，将桥梁的相对变形转化为支座的剪切变形与平板摩擦部的水平错动，在竖向上支座与平板摩擦部共同承担桥梁的竖向荷载；本发明竖向承载力高，具备自复位能力，原理清晰明确，构造简单，性能稳定，生产方便，可实现多阶段耗能，满足桥梁正常使用的同时可以应对多级地震，具有较强的抗破坏能力，应用前景广阔。
