Friction pendulum type bridge seismic mitigation and absorption support
The invention relates to the technical field of buildings and bridges, and discloses a friction pendulum type bridge seismic mitigation and absorption support which is characterized in that the rear side of an upper steel plate is fixedly connected with a first protective plate in a transverse C shape, the bottom of the first protective plate is slidably connected with a second protective plate ina C shape, and the interior of the second protective plate is fixedly connected with a lower steel plate; the lower steel plate and the upper steel plate are located at the same vertical position, alower fixing block is fixedly connected to the top of the lower steel plate, a sliding groove is formed in the top of the lower steel plate, a first vibration reduction device is arranged at the top of the lower fixing block, a second vibration reduction device is arranged in the sliding groove, and a protection fixing device is arranged at the front side of the upper steel plate. According to thefriction pendulum type bridge seismic mitigation and isolation support, three times of mitigation of bridge vibration can be achieved, a bridge is protected to a certain degree, the impact force of the vibration is reduced, the impact force of the vibration on a bridge structure is reduced, and then the bridge structure can be used for a longer time.
本发明涉及建筑及桥梁技术领域，且公开了一种摩擦摆式桥梁减隔震支座，上钢板后侧固定连接第一防护板为横向“C”字形，第一防护板底部滑动连接第二防护板同样为“C”字形，第二防护板的内部固定连接有下钢板，下钢板与上钢板在同一竖直位置，下钢板的顶部固定连接有下固定块，下钢板的顶部开设有滑槽，下固定块的顶部设置有第一减缓震动装置，滑槽的内部设置有第二减缓装置，上钢板的前侧设置有防护固定装置，该摩擦摆式桥梁减隔震支座能够实现对桥梁震动的三次减缓，使桥梁得到一定程度上的防护，使震动的冲击力得到降低，使得震动对桥梁结构的冲力得到降低，进而使桥梁的结构可以更加持久的进行使用。
