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.
