Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a recyclable wire rope lifting ring for a cantilever scaffold and a use method thereof. Background Art

[0002] Cantilever scaffolding refers to a scaffolding structure that unloads its structure onto a rigid cantilever beam (frame) attached to the building structure. It is used for construction work and safety protection needs for main or decoration projects during building construction. During the erection of cantilever scaffolding in residential construction, a steel wire rope or steel tie rod should be installed at the outer end of each steel cantilever beam to connect it to the upper building structure. The lifting rings that connect the steel wire rope to the building structure cannot be removed after being embedded. The protruding parts need to be manually cut off a second time. If the removal is not in place, rework is required. This results in a large amount of human resources being wasted in the later construction process. It also wastes resources on the steel bars reserved in the building structure, increases cost losses, and thus increases construction costs. Summary of the Invention
