Background

The overhanging scaffold is a scaffold in which a frame body structure is unloaded on a rigid overhanging beam (frame) attached to a building structure, and is commonly used for main body or decoration engineering operation in building construction. The building technology is mature, the operation is convenient and fast, and the economic benefit is high, so that the building technology is widely applied to high-rise buildings at present.

According to the requirements of 6.10.7 in the technical Specification for safety of scaffold of fastener steel tube for building construction (JGJ 130-2011): the overhanging end of the section steel overhanging beam is provided with a positioning point which can reliably fix the scaffold upright rod and the steel beam, and the distance between the positioning point and the end part of the overhanging beam is not less than 100 mm. The effect of the scaffold steel tube is mainly to prevent the scaffold steel tube from generating lateral displacement and ensure the stability of the scaffold body. Therefore, the limiting steel bars are welded on the existing profile steel cantilever beam to serve as fixing positioning points of the scaffold upright rod and the steel beam.

In the traditional limit steel bar construction, I-shaped steel (section steel cantilever beam or steel beam) is positioned and installed at a designated position, and then a professional electric welder performs welding operation on a floor. The behavior not only has larger potential safety hazards such as high falling, object striking and the like, but also brings serious potential safety hazards to the external scaffold; in addition, when the reinforcing steel bar heads are welded, if deviation occurs in positioning and fixing or the frame body needs to be adjusted, the reinforcing steel bar heads need to be welded again, and manpower and material resources are wasted.
