Three-way seismic mitigation and isolation bridge support
The invention provides a three-way seismic mitigation and isolation bridge support which comprises a base plate, a lower swing sliding block, an upper swing sliding block, a tensile mechanism and an upper base plate, the lower swing sliding block is slidably installed on the base plate in the first direction, and the lower surface of the upper swing sliding block is slidably connected with the upper surface of the lower swing sliding block; the tensile mechanism is arranged between the lower swing sliding block and the upper swing sliding block so that the lower swing sliding block and the upper swing sliding block can rotate around the central axis of the tensile mechanism at the same time and deflect towards any side by deviating from the central axis of the tensile mechanism. The upper seat plate is slidably installed on the upper swing sliding block in the second direction so that the beam body and the pier can relatively slide in the first direction and/or the second direction, relatively rotate around the central axis of the tensile mechanism and/or relatively deflect towards any side by deviating from the central axis of the tensile mechanism. Therefore, damping and limiting in three directions can be achieved, an earthquake is buffered and dissipated, beam falling is prevented, and damage to a bridge pier and a beam body is relieved.
本发明提供了一种三向减隔震桥梁支座，包括底座板、下摆滑动块、上摆滑动块、抗拉机构以及上座板，下摆滑动块沿第一方向可滑动地安装在底座板上，上摆滑动块的下表面与下摆滑动块的上表面之间滑动连接；抗拉机构设置在下摆滑动块和上摆滑动块之间以使下摆滑动块和上摆滑动块之间能够同时绕抗拉机构的中轴线旋转以及偏离抗拉机构的中轴线向任意一侧偏转；上座板沿第二方向可滑动地安装在上摆滑动块上以使梁体与桥墩之间能够沿第一方向和/或第二方向相对滑动以及绕抗拉机构的中轴线相对旋转和/或偏离抗拉机构的中轴线向任意一侧相对偏转。从而能够实现三个方向的减震和限位，对地震进行缓冲和消散，防止落梁的发生并减轻对桥墩和梁体的损伤。
