Anti-seismic check block structure for limiting bidirectional movement of bridge
The invention relates to the technical field of bridge seismic resistance, and particularly relates to an anti-seismic check block structure for limiting bidirectional movement of a bridge. The structure comprises a steel corbel, a fixed top plate and an anti-seismic check block, the steel corbel is fixed above the side wall of a bridge pier through a steel corbel bolt, the fixed top plate is fixed at the top of the steel corbel, the anti-seismic check block is arranged on the upper portion of the fixed top plate, two vertical baffles are arranged on the top of the anti-seismic check block, and collision rubbers are arranged on the lower portions and the middle portions of the inner walls of the vertical baffles; and a beam plate is fixed to the bottom of the main beam, a connecting baffle is arranged in the middle of the lower surface of the beam plate, the bottom of the connecting baffle is connected with a collision cylinder, and the collision cylinder is located among the four pieces of collision rubbers. Large displacement of the bridge in the transverse bridge direction and the vertical bridge direction during an earthquake can be efficiently limited, the bridge is prevented from being damaged due to beam falling, the possibility that the bridge collides at the expansion joint is reduced, and the bridge deck and the bottom of the bridge pier of the bridge are effectively protected.
本发明涉及桥梁抗震技术领域，尤其涉及一种限制桥梁双向移动的抗震挡块结构，包括钢牛腿、固定顶板、和抗震挡块，所述钢牛腿通过钢牛腿螺栓固定于桥墩的侧壁上方，所述固定顶板固定于所述钢牛腿的顶部，所述抗震挡块设置于所述固定顶板上部，所述抗震挡块的顶部设有与两块竖挡板，所述竖挡板的内壁下方和内壁中部设有碰撞橡胶；所述所述梁板固定于主梁的底部，其下表面中部设有连接挡板，所述连接挡板的底部连接有碰撞圆筒，所述碰撞圆筒位于四个所述碰撞橡胶中间。本发明能够高效的限制地震时桥梁在横桥向与竖向发生较大的位移，防止桥梁发生落梁损坏，减小桥梁在伸缩缝处碰撞的可能性，有效保护桥梁的桥面与桥墩底部。
