Multi-directional buffer limiting energy dissipation resettable bridge anti-seismic check block structure
The invention discloses a multi-directional buffering limiting energy dissipation resettable type bridge anti-seismic check block structure. The structure comprises a steel corbel and a stop block structure, the steel corbel is fixed above the side wall of the pier through a steel corbel bolt; the stop block structure comprises a steel top plate fixed to the bottom of the main beam through a steeltop plate bolt and a square stop block fixed to the top of the steel corbel. A concave stop block of an inverted-U-shaped structure is fixed to the bottom of the steel top plate. A rough friction face is formed on the upper surface of the square check block and makes close contact with the top of the groove in the bottom of the concave check block, and a plurality of check block compression springs are arranged between the upper portion of the side wall of the square check block and the side wall of the groove in the bottom of the concave check block. The multi-directional limiting energy dissipation device can achieve multi-directional limiting energy dissipation, and is low in material price, simple in structure and convenient to construct.
本发明公开了一种多向缓冲限位耗能可复位型桥梁抗震挡块结构，包括钢牛腿、挡块结构，所述钢牛腿通过钢牛腿螺栓固定在桥墩侧壁上方，所述挡块结构包括通过钢顶板螺栓固定于主梁底部的钢顶板、固定于所述钢牛腿顶部的方形挡块，所述钢顶板的底部固定有呈倒“凹”形结构的凹形挡块，所述方形挡块的上表面形成粗糙的摩擦面，所述摩擦面与所述凹形挡块底部的凹槽顶部紧密接触，所述方形挡块的侧壁上方与所述凹形挡块底部的凹槽侧壁之间设有若干挡块压缩弹簧。本发明能多向限位耗能，本发明材料价格低，构造简单，施工方便。
