Anti-seismic prefabricated part for bridge
The invention relates to the technical field of building materials, in particular to an anti-seismic prefabricated part for a bridge, which comprises limiting steel bars symmetrically arranged along a vertical plane and anchoring steel bars fixedly connected to the sides, away from each other, of the limiting steel bars, and the anchoring steel bars are distributed in the length direction of the limiting steel bars in an array mode. Embedding grooves are formed in the sides, close to each other, of the two limiting steel bars, a rubber strip is arranged between the limiting steel bars, the two ends of the rubber strip are embedded in the embedding grooves, an elastic piece is further arranged between the two limiting steel bars, the elastic piece comprises a bent part and clamping parts arranged on the two sides of the bent part, clamping grooves are formed in the inner walls of the embedding grooves, and the clamping parts are clamped in the clamping grooves. A cavity allowing the clamping portion of the elastic piece to be inserted into the clamping groove is formed between the rubber strip and the embedding groove, and a balancing weight is fixedly connected to the elastic piece. By setting the deformation threshold value of the balancing weight, the breaking strength and the buffering performance of the bridge are improved, meanwhile, the balancing weight plays a role of a damper, and the influence of small vibration on the limiting steel bars is reduced.
本发明涉及建筑材料技术领域，具体涉及一种桥梁用抗震预制件，包括沿竖直平面对称设置的限位钢条以及固定连接在限位钢条相互远离一侧的锚固钢筋，锚固钢筋沿限位钢条的长度方向阵列分布，两根限位钢条相互靠近的一侧开设有嵌合槽，限位钢条之间设置有橡胶条，橡胶条的两端嵌合在嵌合槽内，两根限位钢条之间还设置有弹性片，弹性片包括弯折部以及设置在弯折部两侧的卡接部，嵌合槽的内壁上开设有卡槽，橡胶条与嵌合槽之间存在有供弹性片的卡接部插入卡槽的空腔，弹性片上固定连接有配重块。本发明通过设置配重块的形变阈值，提升桥梁的断裂强度以及缓冲性能，同时配重块起到阻尼器的作用，减小较小震动对限位钢条的影响。
