Abstract

The invention relates to a temporary fitting for mounting oversized special-shaped steel tower column segments, which structurally comprises an upper right-angled plate, a lower right-angled plate and steel cushion blocks, wherein the upper right-angled plate and the lower right-angled plate are connected with wall plates of an upper tower column segment and a lower tower column segment, and the steel cushion blocks are arranged between an upper welding seam and a lower welding seam and between the upper right-angled plate and the lower right-angled plate. The upper and lower right-angled plates are provided with two phi42 holes, and a near-wall plate end is provided with two phi40 holes. A positioning anchoring system comprises phi40 punch nails and M39 high-strength bolts, the phi40 punch nails are nailed into the two phi42 holes between the upper and lower right-angled plates, and the two phi42 holes are fixed by the M39 high-strength bolts. Uniformity of mounting linearity and production linearity of steel-structure tower columns can be guaranteed by using the temporary fitting for correct positioning. Hooks can be loosened for welding after the temporary fitting is fixed, and horizontal force and bending moment generated during inclining of steel tower column segments can be counteracted by the temporary fitting system having a temporary fixing function. Shrinkage and deformation generated during girth welding and perpendicular to circular seams can be prevented.

Description

technical field [0001] The invention relates to a device for assembling and positioning a steel structure tower column, in particular to an assembly and positioning device suitable for a steel structure tower column in a super large heterogeneous space. Background technique [0002] Since steel structure towers are of great significance to shortening the construction period of bridges, environmental protection, and sustainable economic development, they have been more and more widely used in the world. Taiyuan Xiangyun Bridge is a steel-concrete composite cable-stayed bridge with a single tower. Compared with the steel structure tower-column cable-stayed bridges completed or under construction in China, the tower columns of Xiangyun Bridge have the characteristics of curve shape, two-way inclination angle, large volume and heavy weight. The space structure form of the tower column is the first in China. [0003] The installation error at the top of the tower column is requi...
