The rectangular parallelepiped units 3 are arranged on both sides of the reference unit 2, and
Are rectangular in a plan view and are linearly arranged in the width direction. Triangular prism units 4 are respectively arranged outside the respective rectangular parallelepiped units 3, and the triangular prism units 4 are rectangular and have a shape different from that of the rectangular parallelepiped units 3 in a plan view, and are arranged linearly in the width direction. Further, the rectangular parallelepiped units 3 and the triangular prism units 4 are alternately arranged on the outer side of each triangular prism unit 4, and a large number of units are arranged in the ceiling portion of the hall 1 with no gap in plan view.

As shown in FIGS. 2 and 3, the rectangular parallelepiped unit 3 has a vertical cross section of a substantially square shape (rectangular shape), and the bottom surface and the peripheral side surface of the skeleton 3a are seated so as to open the upper surface of the prism in the horizontal laid state.
