Connecting structure of self-resetting prefabricated concrete-filled steel tube pier and splicing method of connecting structure
The invention relates to the technical field of highway bridge construction engineering, and discloses a connecting structure of a self-resetting prefabricated concrete-filled steel tube pier and a splicing method of the connecting structure. The connecting structure comprises a pier, a bearing platform, a cover beam, a prestressed tendon pipeline, a high-strength steel strand and an anchor rod, the bent cap is located at the top of the pier, and vertically-through prestressed tendon pipelines are reserved in the bent cap and the pier; the high-strength steel strand is arranged in the prestressed tendon pipeline and penetrates through the bent cap and the pier, the top end of the high-strength steel strand is anchored to the upper end of the bent cap, and the lower end of the high-strength steel strand is anchored to the bottom of the pier to provide a self-resetting function and an anti-pulling function; the piers and the bearing platforms are connected through anchor rods. The construction form can shorten the construction period and save the economic cost; the low-yield-point steel plates and the high-strength steel strands in the structure provide energy dissipation capacity and a self-resetting function, so that the pier has good performance under the earthquake action.
本发明涉及公路桥梁建设工程技术领域，公开了一种自复位预制钢管混凝土墩的连接构造及其拼接方法。连接构造包括桥墩、承台，还包括盖梁、预应力筋管道、高强钢绞线、锚杆；盖梁位于桥墩顶部，盖梁和桥墩中均预留有竖向贯通的预应力筋管道；高强钢绞线置于预应力筋管道并穿过盖梁和桥墩，其顶端锚固于盖梁上端部，其下端锚固于桥墩底部，以提供自复位功能与抗拔功能；桥墩和承台通过锚杆连接。该构造形式能够缩短工期，节省经济成本；构造中的低屈服点钢板以及高强钢绞线提供了耗能能力与自复位功能，使桥墩在地震作用下具有良好的性能。
