Full-prefabricated bridge swing self-resetting damping structure system for inverted T-shaped bent cap
The invention relates to a full-prefabricated bridge swing self-resetting damping structure system for an inverted T-shaped bent cap. The system comprises two groups of prefabricated main beams, the prefabricated inverted T-shaped bent cap, a bearing platform, prestressed steel beams, two prefabricated bridge piers and a pile foundation, the top surface of the pile foundation is fixedly connected with the bottom surface of the bearing platform, the prefabricated bridge piers are vertically arranged on the bearing platform, the bottom face of the prefabricated inverted T-shaped bent cap is fixedly connected with the top faces of the two prefabricated bridge piers respectively, the two groups of prefabricated main beams are arranged on the shoulders of the two sides of the prefabricated inverted T-shaped bent cap respectively, U-shaped prestressed pipelines are arranged in the prefabricated bridge piers, the prefabricated inverted T-shaped bent cap and the bearing platform, the prestressed steel beams are arranged in the U-shaped prestressed pipelines, the end parts of the prestressed steel beams extend out of the U-shaped prestressed pipelines and then are fixedly connected with the prefabricated inverted T-shaped bent cap, and a swing interface is formed between the contact surfaces of the prefabricated bridge piers and the bearing platform. Compared with the prior art, the system has the advantages of being good in anti-seismic performance, low in construction difficulty, low in cost, convenient to overhaul and maintain and the like.
本发明涉及一种用于倒T盖梁的全预制桥梁摇摆自复位减震结构体系，包括两组预制主梁、预制倒T盖梁、承台、预应力钢束、两个预制桥墩和桩基，桩基的顶面与承台的底面固定连接，预制桥墩竖直设于承台上，预制倒T盖梁的底面分别与两个预制桥墩的顶面固定连接，两组预制主梁分别设于所述预制倒T盖梁的两侧的肩部，预制桥墩、预制倒T盖梁、承台内设置U型预应力管道，预应力钢束设于U型预应力管道内，预应力钢束的端部伸出U型预应力管道后与预制倒T盖梁固定连接，预制桥墩与承台的接触面间形成摇摆界面。与现有技术相比，本发明具有抗震性能好，施工难度低、成本低、检修维护便捷等优点。
