Mounting method of special-shaped steel structure and mounting method of steel grid structure

Abstract

The invention provides a mounting method of a special-shaped steel structure and a mounting method of a steel grid structure. The mounting method of the special-shaped steel structure comprises the following steps that the special-shaped steel structure is sequentially divided into a vertical section, a transition section and a horizontal section from high to low according to the structural characteristics of the special-shaped steel structure; an operation platform is erected on the external wall of a tower building, and the operation platform is used to fix scattered pieces in the vertical section and connect the scattered pieces integrally; a plurality of first temporary supports are arranged on the roof of a skirt building at the periphery of the tower building, and the transition section is hoisted to a set mounting position; and a plurality of branch columns are mounted on the roof of the skirt building, and the branch columns are used as the centers to assemble all the scatteredpieces of the horizontal section and connect the scattered pieces into a whole. According to the mounting method of the special-shaped steel structure and the mounting method of the steel grid structure, by using a top-down reverse construction method, the vertical section, the transition section and the horizontal section are sequentially mounted, the tower building is used as the center, mounting is carried out from inside to outside, the site utilization rate can be increased greatly, and meanwhile the control over the structural stability is more reasonable.

Description

technical field [0001] The invention relates to the technical field of super high-rise steel structure engineering construction, in particular to a method for installing a special-shaped steel structure and a method for installing a steel grid structure. Background technique [0002] With the rapid development of the construction industry and the continuous improvement of construction technology, many steel grid structures with strange shapes, hyperbolic shapes or curved surfaces have emerged in super high-rise buildings to achieve changing curves, lightness and elegance. visual effects. This kind of steel grid structure usually extends from the facade of the super high-rise tower from top to bottom gradually to the far side of the tower or extends and covers the podium around the tower to form a large space canopy structure or the roof of the podium. [0003] The initial section of the overhanging extension of the steel grid structure usually extends vertically and is rela...
