Main tower vertical rotating structure system of single-tower double-layer steel truss girder cable-stayed bridge
The invention discloses a main tower vertical rotating structure system of a single-tower double-layer steel truss girder cable-stayed bridge, and relates to the technical field of bridge engineering design. The tower column is arranged at the top of the main cross beam; the connecting piece is connected with the tower column; the main tower is rotationally connected with the tower column through a connecting piece; the pressing rod is arranged on one side of the main tower; and one end of the steel strand pull rod is connected with the pressing rod, and the other end of the steel strand pull rod is connected with the main tower. The direction of the acting force of the steel strand traction cable on the main tower can be changed through the pressing rod, so that the main tower can rotate around the tower column under the action of the connecting piece, lifting and vertical rotation of the main tower are achieved in cooperation with the back cable and the tensioning oil cylinder, the project quality, the construction safety and the project construction period requirement are guaranteed, and the mounting line shape and the welding quality of the main tower are better controlled; and the urban land and the construction cost are saved, and the urban landscape is beautified.
本发明公开了一种独塔双层钢桁梁斜拉桥主塔竖转结构体系，涉及桥梁工程设计技术领域，包括：主横梁；塔柱，所述塔柱设置在主横梁顶部；连接件，所述连接件和塔柱连接；主塔，所述主塔和塔柱通过连接件转动连接；压杆，所述压杆设置在主塔一侧；钢绞线拉杆，所述钢绞线拉杆的一端和压杆连接，所述钢绞线拉杆的另一端和主塔连接。本发明能够通过压杆改变钢绞线牵引索对主塔作用力的方向，使得主塔能够在连接件的作用下，围绕塔柱旋转，配合背索和张紧油缸，实现主塔的提升竖转，保证了工程质量、施工安全和项目工期要求，更好地控制主塔安装线形及焊接质量；且节约城市用地及工程造价，美化了城市景观。
