Saw-shaped gear rotation buffering energy dissipation type anti-seismic check block structure
The invention relates to the technical field of bridge seismic resistance, in particular to a saw-shaped gear rotation buffering energy dissipation type anti-seismic check block structure which comprises a steel corbel, a steel check block, an upper fixing plate, a trapezoidal connecting block, a curved surface connecting block and a saw-shaped gear, and the steel corbel is fixed above the side wall of a pier through a steel corbel bolt; the two hinged supports are fixed to the top of the steel corbel, the saw-shaped gear is arranged at the top end of the rotating plate, and the rotating plateis hinged to the hinged supports. The curved surface connecting block is fixed to the bottom of a main beam through the upper fixing plate, the two steel check blocks are fixed to the two ends of thecurved surface connecting block, the cross section of the curved surface connecting block is approximately of an isosceles triangle structure, and tooth belts meshed with the saw-shaped gear in a matched mode are formed on the two bevel edges of the curved surface connecting block. Energy consumption can be effectively buffered, large-amplitude displacement of the beam body is limited, and meanwhile damage to the check block is reduced.
本发明涉及桥梁抗震技术领域，尤其涉及一种锯型齿轮转动缓冲耗能型抗震挡块结构，包括钢牛腿、钢挡块、上固定板、梯形连接块、曲面连接块、锯型齿轮，所述钢牛腿通过钢牛腿螺栓固定在桥墩侧壁上方；两个铰支座固定于所述钢牛腿顶部，所述锯型齿轮设置于转动板的顶端，所述转动板与铰支座铰接；所述曲面连接块通过所述上固定板固定于主梁的底部，两个所述钢挡块固定于所述曲面连接块的两端，所述曲面连接块的横截面大致呈等腰三角形结构，其两斜边上形成与所述锯型齿轮匹配啮合的齿带。本发明能够有效地缓冲耗能，限制梁体大幅度位移的同时减少挡块自身受损。
