And do the same work. That is, first, the load of the gondola 11 is reduced by connecting the upper end of the wire rope 34 that suspends the gondola 11 to a fired material (not shown). Next, the projecting beam 106 is detached from the column 101a, and attached to the upper end of the column 101b with a bolt 107. The column 101b to which the projecting beam 106 is attached is lifted and supported by a large crane, and each column 10b is supported.
The column 101b is added to the upper part of 1a. Finally, the wire rope 34 connected to the fired material is connected to the girder 106, and the load of the gondola 11 applied to the fired material is
Return to 1. Then, the gondola 11 is raised to a predetermined position again by synchronously operating the endless winches 35 and winding up the wire rope 34. By repeating such work, a multi-story parking lot will be constructed by assembling the steel frame to the top.

Before the operation, the size of the gondola 11 is adjusted with respect to the interval between the columns 101. In the case of this embodiment,
As shown in FIGS. 2 and 3, the fixing positions of the moving plates 18 and 22 fixed by the fixing bolts 49 are fixed holes 45 and 4.
By selecting from 6 performs, but fixed in the fixing hole 45 is minimum becomes bulging amount L _S, fixed in the fixing hole 46 is maximum becomes bulging amount L _B.
