Bridge pier-bent cap assembly type ductile connection structure
The invention belongs to the technical field of bridge engineering, and particularly relates to a bridge pier-cover beam assembly type ductility connecting structure which comprises a cover beam, bridge piers, brackets, finish rolling twisted steel bars, ductility rods and steel conversion blocks, the cover beam is arranged between the two bridge piers, and the upper sides and the lower sides of the two ends of the cover beam are concaved inwards to form reserved grooves; the two end heads of the bent cap form inverted-T-shaped structures; the bracket is arranged on the bridge pier, and the bracket and the bridge pier are poured into a whole; a steel conversion block is arranged in a preformed groove of a cover beam, then the cover beam is connected with the steel conversion block through matching of a finish rolling twisted steel bar, a nut and the steel conversion block which are embedded in the length direction of the cover beam, and the pier is connected with the steel conversion block through matching of a ductility rod and a high-strength bolt which are embedded in the pier. Therefore, the bent cap and the pier are rapidly connected into a whole, the problems that in the prior art, the connecting mode is complex, the construction difficulty is large, and the economic feasibility is low are solved, and the anti-seismic performance of the structure is effectively improved.
本发明属于桥梁工程技术领域，具体涉及一种桥墩‑盖梁的装配式延性连接构造，本连接构造包括盖梁、桥墩、牛腿、精轧螺纹钢筋、延性杆、钢转换块，盖梁设置在两桥墩之间，盖梁两端端头上下侧向内凹陷形成预留槽，使盖梁两端端头均形成凸字形结构；牛腿设置在桥墩上，牛腿与桥墩浇筑为一体；通过在盖梁的预留槽内设置钢转换块，然后盖梁通过沿着盖梁长度方向预埋的精轧螺纹钢筋、螺母、钢转换块相配合，实现盖梁与钢转换块的连接，桥墩则通过其内部预埋的延性杆与高强螺栓配合实现桥墩与钢转换块的连接，从而使得盖梁与桥墩快速连接成为整体，解决了现有技术中连接方式复杂、施工难度大、经济可行性低的问题，并且有效地提高了结构的抗震性能。
