As described above, FIG. 1, FIG. 2 and FIG.
A two-story building as shown in 8 is constructed. Figure 1
In the two-story building shown in FIG. 2, the pair of floor frames 100 that are fixed to each other so as to be separable from each other constitutes the floor frame of the second floor, and the foundation floor frame 800 constitutes the floor frame of the first floor. To do. 22 and 23 partially show a state in which wall boards, windows, etc. are arranged in the two-story building assembled as described above. Although the doorway, stairs, etc. are not shown, it is easy to install them appropriately.

The above-described embodiment of the three-dimensional structure according to the present invention is a two-story building, but in the half unit HU, all the components arranged on the lower surface of the floor frame 100 are removed. For example, in the state where each of the half units HU is placed in one unit, the pair of floor frames 100 that are fixed so as to be separable from each other constitute the floor frame of the first floor. Therefore, the present invention can also be applied to a one-story three-dimensional structure.

The three-dimensional structure according to the present invention is composed of only a pair of half units HU, and in the case of a one-story building, each half unit HU has a floor frame 100,
The side wall frame 200, the roof frame 300, and the pair of end wall frames 4
The main constituent elements of the one-story three-dimensional structure such as 00 are configured as a unit, and by fixing the floor frame bodies 100 to each other so that they can be separated from each other, it is possible to easily and quickly put them into one unit. The construction time can be greatly reduced and it is practically useful. Moreover, the floor frame 10
Since the side wall frame body 200, the roof frame body 300, and the pair of end wall frame bodies 400 can be folded in a stacked state on the upper surface of 0, the configuration is made compact, and the efficiency of transportation and storage is improved. Furthermore, the side wall frame body 200, the roof frame body 300, and the pair of end wall frame bodies 400 arranged on the upper surface of the floor frame body 100 can be positioned at the use position by a simple operation including a turning operation. Enables quick construction with less effort. On the contrary, the turning operation from the use position to the folding position can be performed easily and quickly. Furthermore, since the connecting means between the constituent elements comprises a cap nut member and a bolt, and the cap nut member is fixed to one of the constituent elements in advance, the assembling workability is better than that of the bolt and nut connecting means. Since the work is improved and the assembly work is further speeded, and the bolt fastening work does not require cooperation with the nut, the work space for fastening the bolt can be reduced, so that the wall plate etc. Even if it exists, it does not hinder the bolt fastening work. Also, it is possible to prevent water such as rainwater from entering. Side wall frame 20
0, the swing support mechanism and the swing lock mechanism of the roof frame 300 and the pair of end wall frames 400 have a simple structure and are excellent in workability. In particular, the swivel lock mechanism has a simple structure because the overlapping part can be unlocked with a single bolt.
The lock operation to the use position becomes easy and quick. In the pair of half units HU, each of the floor frame bodies 100, each of the side wall frame bodies 200, each of the roof frame bodies 300, and each of the end wall frame bodies 400 can be a common component. To further promote costdown.

The three-dimensional structure according to the invention, even in the case of a two-story building, consists of only a pair of half units HU. Moreover, each of the half units HU has a floor frame 10
0, the side wall frame 200, the roof frame 300, the pair of end wall frames 400, the lower side wall frame 500 and the pair of lower end wall frames 60.
By adding 0, the main constituent elements of the two-story three-dimensional structure are configured as a unit, and by fixing the floor frame bodies 100 to each other so that they can be separated from each other, it is possible to easily and quickly form one unit. The total construction time can be greatly reduced, which is practically useful. Moreover, in addition to the side wall frame 200, the roof frame 300 and the pair of end wall frames 400 being foldable in a stacked state on the upper surface of the floor frame 100, the lower wall of the floor frame 100 can be Since the frame body 500 and the pair of lower end wall frame bodies 600 can be folded in a stacked state, the structure can be made compact and the efficiency of transportation and storage can be improved despite the two-story structure. Furthermore, the lower side wall frame body 500 disposed on the lower surface of the floor frame body 100.
Since the pair of lower end wall frames 600 can be positioned at the use position by a simple operation including a turning operation, quick construction is possible with less labor. On the contrary, the operation from the use position to the folding position can be easily and quickly performed. Furthermore, there is no need to build scaffolding while constructing a two-story three-dimensional structure. Other configurations and effects are substantially the same as those in the above-mentioned one-story three-dimensional structure, and thus description thereof will be omitted.

In each of the half units HU in the above-described embodiment of the present invention, the planar shape of each of the end wall frames 400 has a rectangular shape, and each of the end wall frames 400 is positioned at the use position. The other end surface included in each of the other end portions of the end wall frames 400 is inclined upward from the one side of the floor frame 100 toward the other side with respect to the upper surface of the floor frame 100. Instead of this embodiment, each of the end wall frame bodies 400 has a rectangular planar shape, and each of the end wall frame bodies 400 is positioned at the use position.
There is also another embodiment in which the other end surface included in each of the other ends is extended from one side of the floor frame body 100 to the other side in parallel with the upper surface of the floor frame body 100. In this embodiment, it is not possible to incline each of the roof frame bodies 300, but if consideration for rain is not necessary, the overall configuration is further simplified, and further cost reduction can be achieved.
