Further, the corner panel member 16 is not limited to the L-shape in plan view with the internal angle being a right angle, and the internal angle may be an acute angle or an obtuse angle. Further, it may be a shape that can stand on its own even if it is a T shape, a cross shape, or the like in plan view.

Furthermore, the wall panel member may not be disposed at both ends of the ceiling rail member 18. For example, the ceiling rail member 18 may protrude in the width direction of the wall panel member and be supported in a cantilever state.

Moreover, the ceiling part 30 can also be constructed after the ceiling rail member 18 is bridged over the corner panel members 16A and 16B.

In the first embodiment, one end of the ceiling rail members 18 and 29 is fixed to the intermediate panel member 28, but only the other end of the ceiling rail members 18 and 29 is fixed to the corner panel members 16A and 16B, respectively. If the rail members 18 and 29 are joined and integrated, the ceiling rail members 18 and 29 may not be fixed to the intermediate panel member 28.
