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 li
