Swivel construction structure of large cantilever steel truss girder and construction method of swivel construction structure
The invention relates to a swivel construction structure of a large cantilever steel truss girder and a construction method of the swivel construction structure, and belongs to the technical field of bridge construction. The swivel construction structure comprises the steel truss girder, the rotary table, the inhaul cable assembly and the buckle cable assembly; pier columns are arranged at the bottom of the steel truss girder, the steel truss girder is divided into a side span section and a middle span section by the pier columns, the middle span section is longer than the side span section, and a ballasting piece is arranged on the side span section. The bottom of the turntable is rotationally connected with a spherical hinge; the inhaul cable assembly comprises a first inhaul cable and a second inhaul cable, the first inhaul cable is obliquely arranged between the rotating disc and the side span section, the second inhaul cable is obliquely arranged between the rotating disc and the middle span section and used for keeping balance in the rotating process of the steel truss girder, and the buckling cable assembly comprises a first buckling cable arranged on the middle span section and a second buckling cable arranged on the side span section. The third buckle cable is arranged on a vertical web member at the top of the pier column, and the two ends of the third buckle cable are fixed to lower chord members of the steel truss girder respectively.
本申请涉及一种大悬臂钢桁梁的转体施工结构及其施工方法，属于桥梁施工技术领域。由于本申请的转体施工结构包括钢桁梁、转盘、拉索组件和扣索组件；钢桁梁底部设置有墩柱，钢桁梁被墩柱分为边跨段和中跨段，中跨段的长度长于边跨段，在边跨段上设置有压重件；转盘设置于墩柱底部，在转盘底部转动连接有球铰；拉索组件包括第一拉索和第二拉索，第一拉索倾斜设置于转盘和边跨段之间，第二拉索倾斜设置于转盘和中跨段之间，用于在钢桁梁的转体过程中保持平衡，扣索组件包括中跨段设置的第一扣索、边跨段设置的第二扣索，以及墩柱顶部的竖向腹杆上设置的第三扣索，第三扣索的两端分别固定于钢桁梁的下弦杆。
