Description

Corner braces for cantilevered scaffolding

technical field

The utility model relates to a steel structure construction device, in particular to a corner support frame of a force-bearing structure at a corner of a cantilevered scaffold.

Background technique

In construction engineering, the treatment method of the steel cantilevered outer frame at the corner of the facade on the construction site generally adopts a radial arrangement of steel beams, which is feasible in the case of corner columns with small cross-sections, but usually the frame columns of high-rise buildings have relatively small cross-sections. Large, radial steel beams are arranged, and generally 1-3 steel cantilever beams are arranged in the frame column, which makes the row column reinforcements deviated, and the concrete at the steel beams inside the column is not dense, affecting The quality of the frame columns may even cause major safety hazards; and the method of arranging the steel beams in a radial manner makes the spacing of the vertical poles at the corners of the outer frame different, and some inner vertical poles fail to fall on the steel beams. There is a phenomenon of empty feet. Due to the arrangement of radial beams at the corners, the length of the cantilever beams is relatively long. Without the cooperation of tower cranes, it is quite inconvenient to remove the steel beams. The steel beams can only be removed after cutting them short, which brings great inconvenience to the construction. It is very inconvenient, consumes labor, wastes materials, and increases construction costs.
