Since the panel is carried into the built-in space, the narrow carry-in path panel having a plurality of panel members can be easily transported through the carry-in path and carried into the built-in space. In addition, since a plurality of panel members can be transported simultaneously, the panel members can be transported efficiently. Further, the plurality of panel members can be folded upright outside the narrow carry-in path, so that the folding operation of the plurality of panel members can be facilitated. Further, after the narrow carry-in panel carried into the building space is installed so as to be arranged at a position where another panel member is to be arranged, at least one is provided.
Since one panel member is angularly displaced with respect to the other panel members and deployed, it is built in the erection space, so that complicated erection work in the erection space is not required and the erection can be easily performed. Further, when at least one panel member is angularly displaced with respect to another panel member,
Since it is guided by the angular displacement guide means, it can be deployed from the folded state without requiring a large-sized special machine or the like, and can be easily assembled.
