Auxiliary supporting equipment for mounting prefabricated balcony

The invention relates to the technical field of building auxiliary supporting frames, in particular to an auxiliary supporting device for prefabricated balcony installation, which comprises six groups of stand column storage assemblies for prefabricated balcony supporting, the storage assemblies are hinged to six groups of stand columns, and the storage assemblies on four groups of stand columns at the left and right ends of the six groups of stand columns are installed in a crossed manner. The storage assembly is used for providing the rapid unfolding and fixing effect when the six sets of stand columns are used for installing and supporting the prefabricated balcony, the expansion assembly is installed at the upper ends of the six sets of stand columns, and the expansion assembly is detachably connected with the six sets of stand columns. The expansion assembly is used for being matched with the six sets of stand columns for installation when the six sets of stand columns are unfolded into different areas.
