Profile steel overhanging type external scaffold

The utility model belongs to the technical field of building construction, and relates to a profile steel overhanging type external scaffold which comprises an overhanging I-shaped beam fixed to a building main body, a pull rod is arranged between the overhanging I-shaped beam and the building main body, and the pull rod comprises a first connecting end connected with the building main body and a second connecting end connected with the overhanging I-shaped beam. A vertical connecting rod is fixedly mounted on the top surface of one side, far away from the building main body, of the cantilever I-shaped beam; the second connecting end of the pull rod is located on the connecting rod and connected with the connecting rod so that the height of the second connecting end of the pull rod can be increased, and therefore the space between the cantilever I-shaped beam and the pull rod can be enlarged. The construction method has the advantages that the space between the pull rod and the cantilever I-shaped beam is eff
