Overhanging scaffold

The utility model discloses a lifting cantilever scaffold which comprises a section steel cantilever beam fixedly installed on the outer side of a girder, a wall penetrating bolt, a bolt sleeve pre-buried in the girder, an iron pipe used for building a scaffold and a connecting piece used for locking the iron pipe. Wherein the profile steel outrigger is fixedly connected with the bolt sleeve through the through-wall bolt, and the iron pipes are mutually locked and fixed through the connecting piece and are fixed on the profile steel outrigger. The bolt sleeves are pre-buried in the girder, sothat the profile steel outriggers can be fixed on the girder through the through-wall bolts, and the iron pipes are combined through the connecting pieces to build the protective guard, so that the profile steel outriggers and the protective guard can be respectively assembled and fixed with each other during installation, and the installation efficiency is improved. And finally, the overhanging scaffold is hoisted to the
