The present invention relates to a three-dimensional structure including a horizontal cross beam that is freely connected and a horizontal vertical beam that is releasably connected between the horizontal cross beams facing in the horizontal and vertical directions. The three-dimensional structure according to the present invention is applied to, for example, a three-dimensional parking lot, a warehouse, a factory, and a store.

The inventor has previously developed and put into practical use a three-dimensional structure that is assembled in a separable manner and placed on a substantially flat surface.

Are separably connected to each other. The horizontal beam members adjacent to each other in the horizontal vertical direction are connected to each other by the vertical beam members so as to be separable from each other.

According to the above-mentioned three-dimensional structure, it is possible to obtain a larger usage space in the same installation area with respect to the three-dimensional structure consisting of the previous pillar structure, and it is easy to expand the area in the horizontal direction and upward. 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.

It is detachably connected via connecting fittings 16 and 18. In addition, since each of the horizontal cross beams 8 does not have a height sufficient for attaching the fence unit 14, a support member 150 formed of a metal plate is horizontally disposed at a predetermined position of each of the horizontal cross beams 8. It is detachably fastened by bolts (not shown) so as to stand upright from the respective surfaces of the cross beams 8 (see also FIGS. 27 and 28). Each support member 150 is provided with a female screw member (not shown) for fastening the connection fitting 16 or 18 with a bolt 144 (see FIG. 16).

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.

In the above-mentioned three-dimensional structure 2, strength members such as reinforcing bars are built in 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, so that the structural members are simple. This makes it easy to manufacture and assemble the component members, shorten the assembly time, and reduce the total cost. Further, the required strength is ensured, and the overall appearance can be simplified and the appearance can be improved.

In the three-dimensional structure 2, all the components are connected to each other by bolts, so that the assembly workability is good, the assembly time is shortened, and recycling is possible.

In the three-dimensional structure 2, by increasing the lengths of the columns 4 and 6 and increasing the number of the receiving portions 24, the area upward can be easily expanded. Moreover, the area in the horizontal horizontal direction can be easily expanded by installing the three-dimensional structure 2 adjacent to the horizontal horizontal direction. In this case, the horizontal lateral outer surface of the column 6 of the one-dimensional structure 2 and the horizontal lateral outer surface of the column 4 of the other three-dimensional structure 2 are opposed to each other with a slight gap therebetween. Therefore, the fence unit 14 is not disposed on the columns 4 and 6 facing each other. Furthermore, in the three-dimensional structure 2, the area in the horizontal and vertical direction can be easily expanded by increasing the number of each of the support columns 4 and the support columns 6 installed at intervals in the horizontal and vertical direction. it can. FIG. 30 shows a three-story three-dimensional structure 200 whose area is expanded in the horizontal and horizontal directions in this way. Further, FIG. 31 shows a five-story three-dimensional structure 300 in which the area is further expanded in addition to the horizontal and horizontal directions and the horizontal and vertical directions.

As shown in FIGS. 1 and 2, the upper ends of the columns 4 and 6 in the three-dimensional structure 2 are each composed of a rectangular horizontal surface 42 and a support unit 44 for attaching the fence unit 14. As shown by a two-dot chain line in FIG. 5, there is another embodiment in which the metal plate 43 covers the horizontal plane 42. The metal plate 43 is fixed to the upper ends of the plurality of reinforcing bars 4R built in the columns 4 and 6 by welding. The metal plates 42 and 43 disposed at both ends of the columns 4 and 6 contribute to increasing the strength of the columns 4 and 6 and also have a function of applying prestress to the concrete.
