The invention relates to a superlarge special-shaped steel tower binding joint angle sample board mounting method, which specifically includes steps of carving a binding joint positioning line corresponding to a ground marking point on a tower column wall board before a tower column gets off a jig frame in the stage that the tower column matches with the assembly and marking crisscrossed joint punching marks; adjusting sections of the tower columns in place on site, finding the joint punching marks of the joint positioning line on the wall board corresponding to the tower column, extending a connecting line of the joint punching marks to the edge of the tower column, positioning a special joint angle sample board according to a parallel line of the vertical line, performing angle positioning of crossbeam joints depending on the joint sample board, positioning structurally according to assembling size of drawings and welding. By the superlarge special-shaped steel tower binding joint angle sample board mounting method, mounting speed of the tower column is increased greatly and structural integrity is guaranteed simultaneously. A joint angle sample board positioning method is used in the superlarge special-shaped tower column binding joint mounting construction for the first time, and the successful experiences of the method can be used for guiding the-like construction.
Description
technical field [0001] The invention relates to an installation method of a large-scale bridge tower column connection system, in particular to an installation method of a super-large special-shaped steel tower column connection system. Background technique [0002] At present, in the design of large cable-stayed bridges, the steel-concrete mixed structure tower column form has been widely used. The commonly used tower column forms of cable-stayed bridges are single-column, double-column, gantry, A-shaped, inverted Y-shaped, and diamond-shaped. The tower column form of Taiyuan Xiangyun Bridge is the first in China where three towers meet in space, and a single tower column is in the shape of a spatial curve. In order to achieve the stability of the stressed structure of the entire tower column, the cable tower is composed of a set of large beams and 19 sets of horizontal connections from bottom to top. The horizontal connection system connects the three tower columns togeth...
