Bridge damping device using super-plastic energy consumption plates and super-elastic energy consumption limiting rods
The invention discloses a bridge damping device using super-plastic energy consumption plates and super-elastic energy consumption limiting rods. An upper connecting steel plate and a lower connecting steel plate of the device are fixed to the bottom face of a beam body and the top face of a pier respectively, energy dissipation and limiting elements are arranged between the upper steel plate and the lower steel plate, and the upper end and the lower end of a superplastic U-shaped energy dissipation alloy plate and a single steel anchoring limiter arranged in pairs are fixed to the upper connecting steel plate and the lower connecting steel plate respectively. The hyperelastic alloy energy consumption limiting rod penetrates through preformed holes of the steel anchoring limiters which are arranged in pairs, the two ends of the hyperelastic alloy energy consumption limiting rod are limited in a one-way mode through nuts, and the nuts are prevented from loosening and falling off through safety pins; and the buffer rubber pad is arranged on the inner side of the steel anchoring limiter steel plate. The free deformation requirement during normal use of the bridge and the multi-stage energy consumption, large earthquake limiting and self-resetting requirements during earthquake resistance design of the bridge are considered, and the device is suitable for the earthquake resistance design of the bridge in a near-fault area under the action of earthquakes with different intensities and has the advantages that the structure is simple, the energy consumption element is good in durability and can be replaced in time, and the cost is low. And timely repair after strong shock is facilitated.
本发明公开了一种用超塑性耗能板和超弹性耗能限位棒的桥梁减震装置。装置的上下连接钢板分别固定于梁体底面和桥墩顶面，上下钢板之间配置耗能和限位元件，超塑性U型耗能合金板的上、下端，和成对配置的钢制锚固限位器的单个分别固定于上、下连接钢板；超弹性合金耗能限位棒穿过成对配置的钢制锚固限位器预留孔，两端用螺母单向限位并借助保险销防止螺母松动和脱落；缓冲橡胶垫安于钢制锚固限位器钢板的内侧。本发明兼顾桥梁正常使用时的自由变形要求，桥梁抗震设计时多级耗能、大震限位和自复位要求，适用于近断层地区的桥梁在不同强度地震作用下的减震设计，此外，本装置具有构造简单，以及耗能元件耐久性好且可及时更换，便于强震后及时修复。
