Ear-shaped energy dissipation piece bridge anti-collision stop block device
The invention discloses an ear-shaped energy consumption piece bridge anti-collision stop block device which comprises an ear-shaped energy consumption piece, the ear-shaped energy consumption piece is pre-buried in a concrete stop block, the head is arranged on the right side of the concrete stop block to resist impact, and the lower end of the ear-shaped energy consumption piece penetrates through the bottom of the stop block and extends into a bent cap to be anchored. Each ear-shaped energy dissipation piece is composed of a fixed stop nut, a head fixing device, an impact stop, an impact transmission rod, a tubular sealing body, non-Newtonian liquid, a metal corrugated pipe, an end plug, an anchoring pier head and an anchoring rod. The bridge anti-collision stop block can solve the problems that a traditional bridge anti-collision stop block is low in energy consumption in an earthquake, a concrete stop block cannot resist impact load energy consumption, damping distribution is uneven, and the self-recovery capacity is poor, so that the concrete stop block is seriously damaged in the earthquake, and then the upper structure of a bridge is seriously damaged. The damper has the advantages of being high in energy dissipation capacity, good in stability, uniform in damping distribution and high in self-recovery capacity.
本发明公开了一种耳型耗能件桥梁防撞挡块装置，包括耳型耗能件，耳型耗能件预埋在混凝土挡块中，头部置于混凝土挡块右侧抗冲击，下端贯穿挡块底部，深入至盖梁中锚固。所述耳型耗能件是由固定挡头螺母、头部固定装置、撞击挡头、撞击传动杆、管状密封体、非牛顿液体、金属波纹管、端部堵头、锚固墩头、锚固杆组成。本发明能够解决传统桥梁防撞挡块在地震中耗能少，混凝土挡块无法抵抗冲击荷载耗能效果，阻尼分布不均匀，自恢复能力差，从而导致混凝土挡块在地震中发生严重破坏，进而导致桥梁上部结构发生严重破坏的问题；具有耗能能力强，稳定性好，阻尼分布均匀，自恢复能力强的特点。
