Tension-compression type sealing and hinging system of swivel bridge and construction method
The invention belongs to the technical field of swivel bridge construction, and particularly provides a tension-compression type sealing and hinging system of a swivel bridge, which comprises an upper rotary table, a lower rotary table, a spherical hinge assembly and a tension unit, the tension unit comprises a plurality of upper connecting assemblies and a plurality of lower connecting assemblies; the multiple upper connecting assemblies are pre-embedded in the periphery of the upper rotary table in the circumferential direction at intervals. The multiple lower connecting assemblies are pre-buried in the top of the lower rotary table in the circumferential direction at intervals and correspond to the upper connecting assemblies in a one-to-one mode. The upper connecting assembly and the lower connecting assembly are connected through a vertical connecting piece. The spherical hinge assembly is connected between the upper rotary table and the lower rotary table; and a sealing and hinging concrete layer is filled between the upper rotary table and the lower rotary table. The system is clear in force transmission and simple in structure, the problems that a traditional sealing hinge is large in number of vertical steel bars, difficult to position, large in welding amount and not prone to guaranteeing quality are effectively solved, the problem that sealing hinge filling concrete is difficult to pour and vibrate is also solved, the construction quality and efficiency are effectively improved, and the construction period is shortened.
本发明属于转体桥梁施工技术领域，具体提供了一种转体桥的拉压式封铰系统，包括上转台、下转台、球铰组件和受拉单元；所述受拉单元包括多个上连接组件和多个下连接组件；多个所述上连接组件沿周向间隔预埋在上转台外周；多个所述下连接组件沿周向间隔预埋在下转台顶部，且与上连接组件一一对应；上连接组件与下连接组件之间通过竖向连接件连接；所述球铰组件连接在上转台与下转台之间；所述上转台与所述下转台之间填充有封铰混凝土层。该系统传力明确、构造简洁、有效规避了传统封铰竖向钢筋数量多、定位难、焊接量大、质量不易保障的难题，也解决了封铰填充混凝土浇筑及振捣困难的问题，有效提高了施工质量与效率，缩短了工期。
