Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel cantilevered outer frame for building construction. Background Art

[0002] Cantilever scaffolding refers to a scaffolding whose structure unloads on a rigid cantilever external frame attached to the building structure. It is used for main construction or decoration engineering operations and safety protection needs in building construction. The height of each section shall not exceed 24m.

[0003] During the erection and use of the cantilever scaffolding, the wire rope or steel tie rod will be used as the tension rod of the cantilever structure. During the erection and use of the inclined cantilever scaffolding, if the tension of the wire rope or steel tie rod is inconsistent, the force on the wire rope or steel tie rod will be different, which will lead to a decrease in the installation reliability of the cantilever scaffolding support. The cantilever scaffolding currently used cannot determine the tension of the wire rope or steel tie rod. The tension of the wire rope or steel tie rod is determined by manual visual inspection, which easily leads to inconsistent tension of the wire rope or steel tie rod. Therefore, a steel cantilever scaffold for construction is proposed to address the above problems. Utility Model Content
