At the time of disassembly, the unit is easily disassembled into individual units 10, 20, 30, and 40 by loosening the wing nut 55 and removing the connection fitting 50. Also, unlike the connection by welding or the like, the individual units 10, 20,
The disassembled individual units 10, 20, 30, 40 are re-used without difficulty in the next location, since they do not deform the 30, 40.

Various structures can be assembled depending on how the individual units 10, 20, 30, 40 are combined. For example, in the arch gate shown in FIG. 9A, a curved ceiling type gate in which the curved units 30, 30 are connected to each other, and long linear units 10, 10 are connected to both sides of the gate. The arch gate shown in FIG. 9B has a wide frontage structure in which a plurality of long straight units 10 are connected to both sides of the gate. The arch gate shown in FIG. 9C has a structure in which curved units 30, 30 are connected to the arch in the horizontal direction and an eave is attached. In the sign tower of FIG. 9D, a combination of the long straight unit 10 and the short straight unit 20 has a geometric three-dimensional structure with rich design. The tent of FIG. 9E has a structure in which a curved unit 30 is used at a corner of a ceiling portion and a rounded ceiling is provided.
