Metal energy dissipation bridge stop block and mounting method thereof
The invention discloses a metal energy dissipation bridge stop block which comprises a lower connecting plate, an upper connecting plate, a side connecting plate, a metal damper, a connecting rod, a limiting plate, a stiffening rib, a first connecting bolt and a second connecting bolt, wherein the metal damper and the connecting rod are arranged between the upper connecting plate and the lower connecting plate. The lower portion of the metal damper is fixedly connected with the lower connecting plate, the upper portion of the metal damper is fixedly connected with the connecting rod, and a certain gap is reserved between the connecting rod and the upper connecting plate. The limiting plates are welded to the lower portion of the upper connecting plate, and the side connecting plate is welded to the sides. A certain distance is reserved between the connecting rod and the bottom edges of the limiting plates, in the normal use state, the connecting rod generates certain displacement in sliding grooves formed by the adjacent limiting plates in the longitudinal bridge direction so as to adapt to main beam stretching caused by temperature changes, and transverse displacement allowed by a bridge superstructure is achieved through elasticoplastic deformation of the metal dampers. And meanwhile, the transverse vibration energy of the structure is dissipated, and the transverse limiting and anti-seismic requirements of different bridges are met through combination of metal dampers of different sizes and numbers.
本发明公开了一种金属耗能桥梁挡块，包括下连接板、上连接板、侧连接板、设置在上连接板和下连接板之间的金属阻尼器和连接杆、限位板、加劲肋、第一连接螺栓和第二连接螺栓。金属阻尼器下部与下连接板固定连接，上部与连接杆固定连接，连接杆与上连接板之间预留一定间隙。上连接板下部焊接限位板，侧边焊接侧连接板。连接杆与限位板底缘预留一定距离，在正常使用状态下，连接杆在相邻限位板形成的滑槽内沿纵桥向发生一定位移以适应温度变化造成的主梁伸缩，并通过金属阻尼器的弹塑性变形实现桥梁上部结构容许的横向位移，同时耗散结构横向振动能量，通过不同尺寸和数量金属阻尼器的组合满足不同桥梁的横向限位和抗震需求。
