Multi-damping buffer energy dissipation type bridge anti-seismic check block structure
The invention discloses a multi-damping buffer energy dissipation type bridge anti-seismic check block structure. The bridge anti-seismic check block structure comprises a steel corbel, a check blockstructure, steel baffles and damper structures, and the steel corbel is fixed to the upper portion of the side wall of a pier through steel corbel bolts; the check block structure is arranged betweenthe steel corbel and a main beam; the four steel baffles are connected with the four side walls of the check block structure through damper structures correspondingly; and the two ends of each damperstructure are connected with the check block structure and the steel baffles through damper side plate bolts respectively. Through the combined action of the multiple damper structures and a middle collision ball, earthquake energy is buffered and consumed; displacement between a beam body and the bridge piers is limited in the transverse bridge direction, the longitudinal bridge direction and thevertical direction, so beam falling is effectively prevented; and rigid collision between a bridge and the check block is converted into flexible collision inside the bridge anti-seismic check blockstructure, and collision between main bodies is transferred to the check block, so damage of earthquakes to the bridge is reduced, and damage to the check block is also reduced.
本发明公开了一种多重阻尼缓冲耗能型桥梁抗震挡块结构，包括钢牛腿、挡块结构、钢挡板和阻尼器结构，所述钢牛腿通过钢牛腿螺栓固定在桥墩侧壁上方；所述挡块结构设置在钢牛腿与主梁之间；四个钢挡板分别通过阻尼器结构与挡块结构的四个侧壁相连；所述阻尼器结构的两端通过阻尼器侧板螺栓分别连接挡块结构与钢挡板。本发明通过多个阻尼器结构和中间的碰撞球共同作用，缓冲消耗地震能量；在横桥向、顺桥向和竖向限制梁体和桥墩之间的位移，有效防止落梁；把桥梁与挡块之间的刚性碰撞转化为此桥梁抗震挡块结构内部的柔性碰撞，把梁体之间的碰撞转移到挡块上，不但减小了地震对桥梁的损伤，也减小了对挡块本身的损伤。
