FIG. 24 shows a state when the receiving stand 120 described above is set on the fork 181 of the forklift vehicle 180, and the forklift vehicle 180, which is a lifting means for raising the receiving stand 120, is shown in FIG. It is carried to the floor 34 in the building where the installation work of the doorway shutter device described in 3 is performed. The fork 181 that moves up and down with respect to the main body of the forklift vehicle 180 includes a vertical extension portion 181A that extends in the vertical direction and a forward extension portion 181C that extends forward from the lower end of the vertical extension portion 181A via the connecting portion 181B. It has an L-shape or a substantially L-shape. After placing the receiving stand 120 on the floor 34, the fork 181 is lowered to advance the forklift vehicle 180, so that the forward extending portion 181C of the fork 181 is formed of the square tube member of the receiving stand 120. It is inserted inside the basic member 121. As a result, the receiving stand 120 is set on the fork 181 of the forklift vehicle 180.

In FIG. 25, the relationship between the basic member 121 and the fork 181 at this time is shown by the fork 181 as a chain double-dashed line. An opening 121A for fitting the vertically extending portion 181A and the connecting portion 181B of the fork 181 is formed on the upper surface of the rear end of each basic member 121, and the opening 121A also opens the rear end surface of the basic member 121. It is supposed to be done. At the rear end of each basic member 121, escape prevention means 183 that closes a part of the opening portion of the opening 121A that opens the rear end surface of the basic member 121 is provided. The escape prevention means 183 includes a bolt 184 in which the shaft portion 184A crosses the opening 121A in the left-right direction, and a nut 185 screwed to the end portion of the shaft portion 184A outside the basic member 121.
