Spatial rotation construction method for steel shed roof structure of ultra-large stadium

Abstract

The invention discloses a spatial rotation construction method for a steel cover shed roof structure of an ultra-large stadium, and belongs to the technical field of constructional engineering. The spatial rotation construction method comprises the steps that a vertical face structure forming a closed ring serves as a supporting structure of a rotation unit, the vertical face structure and the rotation unit are connected through a rotating hinge, and the rotation unit is lifted in place through lifting equipment; in the rotation unit lifting stage, different types of rotation units are lifted in a staged mode, the east-west double-petal rotation units are firstly and symmetrically lifted, then the south-north double-petal rotation units are symmetrically lifted, after an inner pressure ring truss of a roof structure forms a closed ring, the inner pressure ring truss serves as a supporting structure of a single petal rotation unit, and the single petal rotation unit is lifted; and after the rotation unit is lifted, remaining rod pieces are inlayed, unloading construction is carried out, and system conversion of the steel cover shed is completed. The vertical face structure which is closed into the ring is used as the supporting structure of the rotation unit, and favorable conditions are created for steel cover shed roof structure spatial rotation construction.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and more specifically relates to a space swivel construction method for a super-large stadium steel shed roof structure. Background technique [0002] In recent years, with the continuous emergence of sports venues, their steel structure roofs have also presented complex, diverse, novel and unique features, and have become landmark public buildings. At present, the commonly used methods for the construction of steel structure roofs of sports venues include high-altitude bulk method, high-altitude sliding method, overall lifting method, overall jacking method, overall hoisting method, and strip or block installation method. However, for the construction of the steel structure roof of the super-large stadium, higher requirements are put forward for the existing construction technology, which poses a huge challenge to the engineering and technical personnel. [0003] The steel stru...

However, for the construction of the steel structure roof of super-large stadiums, higher requirements are put forward for the existing construction technology, which poses a huge challenge to engineers and technicians

[0003] The steel structure roof of a super-large stadium has the characteristics of large cantilever span, large component size, heavy component weight, and high structural height. High height, large amount of high-altitude hoisting, and difficult welding quality are not conducive to the control of construction cost, quality, and safety

However, the single overall lifting method, overall jacking method, overall hoisting method, and strip or block installation method are difficult to apply to the construction of this type of steel structure roof.
