Buffer type variable-rigidity anti-seismic steel stop block
The invention discloses a buffer type variable-rigidity anti-seismic steel stop block which comprises a stop block body and a rubber block. The rubber block is detachably connected to one side of a bridge of the stop block main body through a bolt, and the stop block main body is detachably connected to the upper surface of a cover beam through a bolt; the rubber block is arranged on one side of the check block, when the bridge and the check block generate impact, the rubber block is compressed at the first time, rubber is in a spherical crown special shape, namely, the contact surface is gradually increased in the contact process, and random collision of the main beam and the check block always makes contact and collision in a first-point and second-point mode; the rigid collision between the bridge and the stop block is avoided, the rigidity changing and buffering effects are achieved, the impact force is greatly reduced, the main beam and the bridge pier structure are protected, and the beam falling risk is reduced.
本发明公开了一种缓冲型变刚度抗震钢挡块，包括：挡块主体、橡胶块；所述橡胶块通过螺栓可拆卸的连接哎挡块主体的桥梁一侧，所述挡块主体通过螺栓可拆卸的连接在盖梁上表面；本发明在挡块的一侧设置橡胶块，在桥梁和挡块产生冲击时，第一时间会先压缩橡胶块，因为橡胶为球冠异型，即在接触的过程中接触面会逐渐的增加，将主梁与挡块的随机碰撞总会以由先点后面的方式接触碰撞，避免了桥梁和挡块的硬性碰撞，起到了变刚度与缓冲作用，大大减小冲击力，保护主梁与桥墩结构，减小落梁风险。
