and S4, adjusting the adjustable jacking to enable the adjustable jacking to be separated from the bottom surface of the cantilever beam.
7. The construction method of the pull-up scaffold for the wide balcony according to claim 6, wherein,
the upward-pulling scaffold for the wide-scene balcony also comprises an adjustable supporting rod for supporting the corresponding layer of structural beam and the floor slab;
the construction method includes the following steps between the step S3 and the step S4:
adjusting support rods are respectively arranged between the bottom surfaces of the current layer and the previous layer of floor slab and the side surfaces of the structural beams, one end of each adjusting support rod arranged on the previous layer is fixed on the bottom surface of the previous layer of floor slab, and the other end of each adjusting support rod is fixed on the structural beam on the previous layer opposite to the connection point of the tensioning rope;
the regulation formula bracing piece one end that sets up on present layer is fixed at present layer floor bottom surface, and the other end passes through the connection piece and fixes on the current layer structure roof beam opposite at the second connecting pipe with the crab-bolt that runs through the connection piece outer lane.
