However, when the number of panel materials A1 is three, when the intermediate panel material A1b is connected to one side in the width direction of the base panel material A1a, the space S (void) left at the end is the base panel material A1a and the intermediate panel material A1b. And formed by. Locking portions 3 are always located on both sides of the space S (void) in the width direction, and hook portions 4 on both sides of the finishing panel material A1c in the width direction make it easy to mount. As described above, in the present invention, when the cylindrical body A is constructed, it is possible to work extremely efficiently by constructing the cylindrical body A in order.

When the cylindrical body A is formed of a plurality of panel materials A1, a gap t may be provided in the panel portions 1 and 1 of the adjacent panel materials A1 and A1 [see FIGS. 1 (C) and 2]. Specifically, the gap t is about 3 mm to about 8 mm. This gap t prevents the panel portions 1 from coming into contact with each other during level adjustment, and prevents the adjacent panel portions 1 from coming into contact with each other during thermal expansion and contraction.

Further, the height dimension of the panel material A1 (base panel material A1a, intermediate panel material A1b, finishing panel material A1c) constituting the cylindrical body A of the present invention is set to be long (specifically, 5 m to 8 m). Regardless of the case, by setting the gap t to the above dimensions, the gap t becomes smaller and the design of the entire cylindrical body A can be improved.

In the figure, the member indicated by reference numeral 9 attached to the gap t is a gasket. Further, the first vertical frame portion 21 is formed with a storage bending portion 21d for accommodating the gasket 9. The storage bent portion for the gasket 9 may be formed on the second vertical frame portion 22 side.
