Assembly-type section steel cantilever protective shed

Abstract

The invention relates to an assembly-type section steel cantilever protective shed which comprises a base and a shed body. The base and a building floor are arranged in parallel, one end of the base is supported on a main structure beam of any building floor, the other end of the base stretches out of the building floor, the base comprises two or more I-shaped steel main beams, a plurality of reinforcing steel bar cross beams are perpendicularly connected between the two I-shaped steel main beams, and a steel plate is laid on the reinforcing steel bar cross beams. A plurality of supporting steel pipes are perpendicularly welded onto the I-shaped steel main beams at intervals, a main steel pipe is welded onto the supporting steel pipes in a supported mode, and a scaffold board is laid on two main steel pipes which are supported on the two I-shaped steel main beams respectively. The shed body comprises a shed body framework and a protective net. The shed body framework comprises a scaffold and framework steel pipes, wherein the scaffold is supported at the near ends of the I-shaped steel main beams and the near end of the building floor, and the framework steel pipes are perpendicularly welded to the far end of the building floor. The protective net is arranged between the scaffold and the framework steel pipes and arranged between every two framework steel pipes in an expanded mode.

Description

Technical field [0001] The invention relates to a construction protection shed, in particular to a prefabricated steel cantilever protection shed. Background technique [0002] In the construction of high-rise buildings, the existing steel cantilevered scaffolding has become a commonly used outer protective body for structure and decoration construction in my country. For example, the high-rise building section steel horizontal cantilever closed hard shelter with patent number CN201220371780.7 adopts one end of a steel wire rope to tie the main beam, and the other end of the steel wire tie to the upper floor panel. The simple tie structure, long-term The use of the easy-pull end of the steel wire rope has low safety performance; in addition, the safety performance of the single-layer structure protective layer is low. Summary of the invention [0003] In view of the above-mentioned shortcomings, the present invention provides a fabricated steel cantilevered protective shed with s...

Problems solved by technology

For example, the patent No. CN201220371780.7 is a high-rise building shaped steel horizontal cantilevered airtight hard protective shed. One end of the steel wire rope is used to tie the main beam, and the other end of the steel rope is tied to the upper floor. Use the easy-to-pull end of the wire rope, which has low safety performance; in addition, the single-layer structure protective layer has low safety performance
