The invention discloses a frame body load-bearing structure at the male corner part of a scaffold erected in sections with a simply supported structure, which overcomes the defects of stress concentration and uneven appearance of the existing cantilever beam structure, is economical and reasonable, and can ensure The construction is safe, and the appearance of the scaffolding is beautiful and uniform. The frame load-bearing structure includes 3 steel beams and 6 cable-stayed wire ropes. The 3 shaped steel beams include: main beam (1), left sub-beam (2), right sub-beam (3); 6 cable-stayed steel wire ropes (4) are respectively arranged at the outer ends of the 3 shaped steel beams, that is, each shaped steel The beam is equipped with two cable-stayed steel wire ropes, one of which is used as a stress rope and the other as a safety protection rope. The main girder is arranged along the bisector of the sun angle, and the left sub-beam and the right sub-beam are respectively arranged on both sides of the main girder, and the included angle with the main girder is 45 degrees, and the intersection of the three is welded into a whole. The length of the left and right sub-beams of the shaped steel beams is the same, and the direction is horizontal. The length of the shaped steel beams other than the corners of the external corners is the same as that of the sub-beams, as long as they are arranged in parallel according to the calculated longitudinal distance of the scaffolding poles. , easy to operate and beautiful in appearance.
