The bearing structure of the frame body at the male corner of the segmented scaffolding

Abstract

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.

Description

technical field [0001] The invention relates to a design of the load-bearing structure of the scaffold body at the corner position of the external scaffold in the external scaffold structure system erected in sections in the construction of high-rise building engineering, in particular to the cantilevered scaffold. Background technique [0002] In recent years, with the acceleration of urbanization, the number of high-rise and super high-rise buildings is increasing day by day. Cantilevered scaffolding is widely used in the following three situations: ①According to the project schedule, the upper body needs to be constructed while the foundation pit is being backfilled structure; ②The main structure of high-rise buildings is surrounded by podiums, and the scaffolding cannot be directly supported on the ground; ③In the construction of super high-rise buildings, the height of scaffolding exceeds the allowable height, so the scaffolding is divided into several sections according...
