FIG.12 and FIG.14 is a side view which shows the support stand 100 for demonstrating the installation method of the support stand 100 which concerns on this embodiment. 11 and 12 illustrate the same process from different angles, and shows a state in which the gantry 130 and the like are carried into the ground part and assembled. 13 and 14 illustrate the same process from different angles, and show a state where the gantry 130 and the like are being lifted from the roof.

  First, each structural member (steel materials 111, 112, etc.) of the roof frame 110 and an iron plate used as the counterweight 102 are carried into the rooftop (step S11). Then, the roof frame 110 is assembled (step S12). On the other hand, components such as the gantry 130, the rod 120, and the wire 122 are carried into the ground portion outside the building 10 (step S22). Next, the mount 130 and the rod 120 installed at the uppermost stage are assembled (step S23).

  Through the above steps, as shown in FIGS. 11 and 12, the roof frame 110 is assembled on the roof, and the rod 120 is assembled on the top of the gantry 130. Since the rod 120 is a rigid bar, it can be erected above the mount 130 as shown. And in the ground part, the wire 122 is connected to the lower part of the top stage base 130 (step S24). The wires 122 and 124 are attached to the gantry 130 at the installation site of the support gantry 100. However, the gantry 130 may be installed at another location and carried into the ground portion of the installation site. .

  Next, on the rooftop, the electric winch 20 for lifting the gantry 130 from the ground portion toward the rooftop is installed (step S13) (see FIGS. 13 and 14). Then, the hook portion 24 provided at the tip of the wire 22 of the electric winch 20 is lowered to the ground portion, and the hook portion 24 is hooked on the wire 26 attached to the gantry 130. And the electric winch 20 is operated on a rooftop, and the mount frame 130 is lifted (step S14). As the wire 22 is wound up by the operation of the electric winch 20, first, the uppermost frame 130, and the rod 120 and the wire 122 connected to the uppermost frame 130 are lifted from the ground (step S24). .

Then, the electric winch 20 is operated to lift the uppermost gantry 130 and the second gantry 130 connected to the lower side together (step S26). Since the wire 122 is a bendable member, when the wire 122 is connected to the gantry 130 on the ground portion, the gantry 130 and the wire 122 can be easily connected. Work in narrow spaces is also possible.

  Then, step S25 and step S26 are repeated until the lifting of all the gantry 130 is completed, and the attachment and lifting of the wire 122 to the gantry 130 are performed step by step (step S27). Note that a wire 124 as a tensile material is connected to the lower part of the lowermost frame 130. 13 and 14 show a state in which a plurality of mounts 130 are lifted by the electric winch 20. As described above, since the gantry 130, the rod 120, and the wires 122 and 124 are lifted from the ground side toward the upper side of the building 10, it is not necessary to separately install a temporary scaffold along the outer wall surface of the building 10. Therefore, the gantry 130 can be installed quickly and easily.

  Next, from the state where all the installation bases 130 are lifted by the electric winch 20 on the rooftop, the one end 110a of the rooftop frame 110 and the upper end 120a of the rod 120 are connected (step S15). At this time, since the rod 120 is a member that does not bend, the upper end 120a of the rod 120 and the one end 110a of the roof frame 110 can be easily connected.

  After the connection between the rod 120 and the roof frame 110 on the rooftop is completed, the lower mounting hardware 170 is installed on the outer wall surface of the building 10 on the ground (step S28). Then, the lower mounting hardware 170 and the wire 124 are connected (step S29). Thereafter, a wall mounting hardware 158 is installed between the pedestal 130 and the outer wall surface, and on the rooftop side, the tension is adjusted by adjusting the turnbuckle 126 attached to the rod 120 connected to the lowest pedestal 130. Is introduced (step S16). On the ground side, tension is introduced by adjusting the turnbuckle 126 attached to the wire 124 (step S30). The installation of the support frame 100 of the present embodiment is completed through the above steps.
