Buffer energy-consuming type bridge anti-earthquake check block capable of rotating in bridge direction
The invention discloses a buffer energy-consuming type bridge anti-earthquake check block capable of rotating in a bridge direction. The check block comprises a steel corbel, a rotating component, buffer energy-consuming devices, steel baffles and collision rubber, wherein the steel corbel is fixed above a side wall of a pier, the rotating component is fixedly installed at the bottom of a main beam through a rotating hinge support, the buffer energy-consuming devices are fixedly connected to the two sides of an inner portion of the rotating component, the steel baffles are fixedly installed onthe upper portion of the steel corbel through the steel baffle bolts, and the steel baffles are located on the two sides of the rotating component. In the invention, overlarge displacement between abeam body and a bridge pier along the bridge direction can be limited; a beam falling phenomenon is prevented, part of earthquake input energy is buffered and consumed by means of compression and stretching deformation of the buffer energy dissipation device; and earthquake energy is absorbed through torsional deformation of a torsion spring and collision deformation of the collision rubber, a damage degree of a bridge is reduced as much as possible, and the check block can reset to an original form along with a recovery effect of the buffer energy-consuming devices and the torsion spring after an earthquake.
本发明公开了一种顺桥向转动缓冲耗能型桥梁抗震挡块，包括钢牛腿、转动构件、缓冲耗能装置、钢挡板和碰撞橡胶，所述钢牛腿固定在桥墩侧壁上方，所述转动构件通过转动铰支座固定安装在主梁的底部，所述缓冲耗能装置固定连接在转动构件内部的两侧，所述钢挡板通过钢挡板螺栓固定安装在钢牛腿上部，钢挡板位于转动构件两侧。本发明能够限制梁体和桥墩之间顺桥向的过大位移，防止发生落梁现象，依靠缓冲耗能装置的压缩和拉伸形变缓冲并消耗一部分地震输入的能量，通过扭转弹簧的扭转变形和碰撞橡胶的碰撞变形来吸收地震的能量，尽可能减小桥梁的损伤程度，并且地震过后随着缓冲耗能装置和扭转弹簧的恢复作用，挡块能复位到原来的形态。
