Collision rotation buffering energy dissipation type bridge anti-seismic check block structure
The invention relates to the technical field of bridge seismic resistance, in particular to a collision rotation buffering energy dissipation type bridge anti-seismic check block structure which comprises a steel corbel, a rotating mechanism, steel baffles, collision cylinders and steel supports, wherein the steel corbel is fixed above the side wall of a pier through a steel corbel bolt; the two steel supports are fixed to the top of the steel corbel, top plates at the top ends of the two steel supports are arranged in a relatively inclined mode, a V-shaped inlet used for allowing the rotatingmechanism to be inserted in is formed between the top plates, and the rotating mechanism is installed at the top of the steel corbel through a third rotating hinge support; the two steel baffles arefixed to the bottom of the main beam through steel baffle bolts, and gaps are formed between the inner walls of the steel baffles and the two collision cylinders at the top of the rotating mechanism.Excessive displacement of the beam body and the bridge piers in the bridge direction can be limited, and the beam falling phenomenon is avoided; rigid collision between the beam body and the check block is converted into flexible collision, and part of earthquake energy is consumed through deformation of the collision cylinder and the torsion spring.
本发明涉及桥梁抗震技术领域，尤其涉及一种碰撞转动缓冲耗能型桥梁抗震挡块结构，包括钢牛腿、转动机构、钢挡板、碰撞圆筒和钢托，所述钢牛腿通过钢牛腿螺栓固定在桥墩侧壁上方；两个所述钢托固定于所述钢牛腿的顶部，两个所述钢托顶端的顶板相对倾斜设置之间形成用于所述转动机构插入的“V”字型入口，所述转动机构通过第三转动铰支座安装于钢牛腿的顶部；两个所述钢挡板通过钢挡板螺栓固定在主梁的底部，所述钢挡板的内壁与所述转动机构顶部的两个碰撞筒体之间设有间隙。本发明能限制梁体和桥墩的顺桥向过大位移，避免发生落梁现象；把梁体和挡块之间的刚性碰撞转化为柔性碰撞，依靠碰撞圆筒和扭转弹簧的变形来消耗一部分地震能量。
