The spatial steel frame bearing construction loads and directly hanging formwork must be calculated by two stage design method recommended in this paper.
The upper end and the lower end of a lifting screw are in a double-self-aligning hanging structure with a self-aligning roller step bearing so that the stress state of the lifting screw is improved.
