Tool type exterior scaffolding of section steel fastening tube

The utility model discloses a steel tube external scaffold for a tool type shaped steel fastener, which is used in building construction. The steel tube external scaffold is more economical, and has wider application range under the premise of ensuring safety. The external scaffold is positioned and supported on a shaped steel beam; one end of the shaped steel beam is fixed on a structural body of a building, and the other end of the shaped steel beam is fixed and connected with the structural body of the building by shearing a wire cable upwards. The structure has the advantages of repeated use and flexible combination, forms the tool type whole set of scaffold system, realizes subsection building and loading, improves the safety factor of the scaffold structure, ensures the construction quality of the scaffold, can increase construction speed, can save construction period and can ensure the successful process of subsequent work. The shaped steel beam is used as a constructional member, and the formed shaped steel beam can be used repeatedly, so the construction cost is greatly reduced. The utility model has favorable economic benefit, and can be popularized and used in the existing building construction.
