Excellent effects such as shortening the assembly time can be obtained. The upright support member made of PC concrete is effective for expanding the installation space in the horizontal and vertical direction, but on the other hand, the amount of the three-dimensional structure protruding from the mutually opposing peripheral edges to the inside in the horizontal and horizontal direction is usually Therefore, the space between each of the upright support members adjacent to each other in the horizontal horizontal direction may be narrowed and may be difficult to use. In addition, since a number of vertical beam members are used to connect each of the upright support members and between the horizontal beam members, the number of parts and assembly man-hours increase, thereby reducing costs and shortening assembly time. There is room for further improvement. Furthermore, since each of the longitudinal beam members is made of H steel and used in large numbers, the cost may increase.

As is clear from this figure, the columns 4 and 6 arranged on the horizontal lateral side edges of the three-dimensional structure 2 are arranged along the side edges at intervals in the horizontal vertical direction. Since there are no other columns inside the columns 4 and 6, the internal space is maximized and is easy to use.

In the three-dimensional structure 2, the main components are the columns 4 and 6, the horizontal horizontal beam 8, the horizontal vertical beam 12, the fence unit 14 and the floor panel 20 made of PC concrete, and there are only six types.
