Prestress tension shear type sealing and hinging system of swivel bridge and construction method of prestress tension shear type sealing and hinging system
The invention belongs to the technical field of swivel bridge construction, and particularly provides a prestress tension-shear 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 prestress tension-shear structure, the prestress tension-shear structure comprises a horizontal anti-shear assembly, a combined assembly and a vertical anti-shear assembly. A plurality of horizontal anti-shearing assemblies are pre-embedded in the side face of the upper rotary table in the circumferential direction at intervals; the plurality of vertical anti-shearing assemblies are pre-buried in the top surface of the lower rotary table at intervals in the circumferential direction, and the vertical anti-shearing assemblies correspond to the horizontal anti-shearing assemblies one to one; the vertical shear-resistant assembly and the horizontal shear-resistant assembly are connected through a combined assembly; the spherical hinge assembly is connected between the upper rotary table and the lower rotary table; and a hinge sealing concrete layer is filled between the upper rotary table and the lower rotary table. According to the system, the combined assembly, the horizontal shear-resistant assembly and the top vertical shear-resistant assembly are used for transmitting tensile force generated by operation bending moment, and new and old concrete vertical joints on the side face of the upper rotary table are firmly connected and definitely transmit force. The number of vertical connecting pieces between the rotary tables is small, the operation space is wide, and the construction quality and efficiency are improved.
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预应力拉剪式封铰系统，包括上转台、下转台、球铰组件和预应力拉剪结构；预应力拉剪结构包括水平抗剪组件、联合组件和竖向抗剪组件；多个水平抗剪组件沿周向间隔预埋在上转台侧面；多个竖向抗剪组件沿周向间隔预埋在下转台顶面，且竖向抗剪组件与水平抗剪组件一一对应；竖向抗剪组件与水平抗剪组件通过联合组件相连；球铰组件连接在上转台与下转台之间；上转台与下转台之间填充有封铰混凝土层。该系统利用联合组件、水平抗剪组件及顶竖向抗剪组件传递因运营弯矩产生的拉力，上转台侧面新老混凝土竖向接缝连接牢靠传力明确。转台之间竖向连接件少，作业空间开阔，提高了施工质量与效率。
