Bridge seismic mitigation and isolation support
The invention provides a bridge seismic mitigation and isolation support and belongs to the field of bridges. The support is characterized in that a base is arranged at the top of a pier; a stand column is fixed to the base and sleeved with a supporting ring, and the inner wall of the supporting ring is connected with the outer wall of the stand column through a plurality of first buffering connecting assemblies; multiple friction assemblies are evenly arranged on the top of the supporting ring, and one longitudinal force guiding assembly is arranged between every two friction assemblies; two auxiliary supporting structures are located on the two sides of the supporting assembly correspondingly, each auxiliary supporting structure comprises an anti-seismic wall and a horizontal force guiding assembly, the anti-seismic wall is arranged on the base, the horizontal force guiding assembly comprises a supporting cylinder and a second buffering connecting piece, one end of the supporting cylinder is connected with the anti-seismic wall, and the other end of the supporting cylinder is connected with one end of the second buffering connecting piece; and the other end of the second buffer connector is connected with the outer wall of the support ring. The support can buffer relative sliding between a bridge and the support, transverse force and longitudinal force are decomposed, the amplitude is reduced, the anti-seismic performance of the bridge support is improved, and the service life of the bridge is prolonged.
本发明提供了一种桥梁减隔震支座，属于桥梁领域，包括：底座设置在桥墩顶部；立柱固定在底座上，支撑环与立柱套接，其内壁通过多个第一缓冲连接组件与立柱外壁连接；多个摩擦组件均匀设置在支撑环顶部，每两个摩擦组件之间设置有一个纵向力导向组件；两组辅助支撑结构分别位于支撑组件两侧，每组辅助支撑结构均包括抗震墙和一组水平力导向组件，抗震墙设置在底座上，水平力导向组件包括支撑筒和第二缓冲连接件，支撑筒一端与抗震墙连接，另一端与第二缓冲连接件一端连接，第二缓冲连接件另一端与支撑环外壁连接。该支座能够缓冲桥梁与支座之间相对滑动，将横向力和纵向力进行分解，减小振幅，提高桥梁支座的抗震性能及延长桥梁的使用寿命。
