[0002]

2. Description of the Related Art Conventionally, a structure of this type is shown in FIG.
As shown in FIG. 5, the iron pipes (30, 31, 32) were inserted into the iron connectors (33, 34) to form a cubic frame. In addition, in the structure of FIG. 22, a connecting plate (42) having a bolt hole (41) is formed at the tip of the pipe (40), and the pillars (K1, K2) and the cross members (L) are formed.
1) and vertical members (L2) and other parts are produced, and the horizontal members (L1) or the vertical members (L2) are arranged between the pillars (K1) and (K2), and the opposing connecting plates (42) 2 in the bolt hole (41)
As shown in FIG. 3, a bolt (b) was put in and tightened with a nut (n) to form an assembled structure.

[0003]

The one described in the prior art, which is shown in FIG. 21, can be easily connected and fixed, but when receiving an external force, the connecting members (33, 34).
The insertion part of the was loosened and twisted or bent, and the original three-dimensional structure could not be maintained. Therefore, it was reinforced with the reinforcing material (35), but the aesthetic effect was impaired and the reinforcing effect was small. Moreover, it was not suitable for a large structure.

In the case of FIG. 22 as well, when it receives an external force, it is twisted or bent. Therefore, a reinforcing material such as a wire rope or a steel bar is needed. Further, since the diameter of the connecting plate (42) is larger than that of the pipe (40), the connecting portion is exposed and the appearance is significantly impaired.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to have a strong connecting force which does not cause twisting or bending, and is excellent in aesthetics and large in size. The purpose is to provide an assembly-type structure that can also be made into a product.

[0006]

In order to achieve the above object, the assembling type structure in the present invention is composed of the following parts, and these connecting parts are made to face each other and fixed by connecting them with bolts and nuts. As a result, various prefabricated structures are formed. Further, it is also possible to complete a stronger structure by temporarily connecting the parts with bolts and nuts and welding the parts. A column (A1) in which an annular portion (R) is provided in the upper portion, and a horizontal frame connecting portion (a) and a vertical frame connecting portion (b) are provided in the annular portion (R). A column (A2) in which an annular portion (R) is provided in the upper portion, and a horizontal frame connecting portion (a) and a vertical frame connecting portion (b) are provided in the annular portion (R). A column (B) in which an annular portion (R) is provided on an upper portion, and a horizontal frame connecting portion (c) and a vertical frame connecting portion (d) are provided in the annular portion (R). A bracket-shaped horizontal frame (C) in which a bracket-shaped material (h) is provided with an inner material (e) and an outer material (f) to form a bracket-shaped frame and a connecting portion (i) is provided . A parenthesis-shaped vertical frame (D) in which a parenthesis-shaped material (wa) is provided with an inner material (n) and an outer material (l) to form a bracket-shaped frame, and a connecting portion (f) is provided on the frame. . Horizontal material (ta) on top of support material (so)
A horizontal frame (E) in which a horizontal member (R) is provided at the bottom to form a frame, and a connecting portion (T) is provided on the frame.

[0007]

In the structure formed as described above, the combination of the column having the annular portion and the frame having the bracket-shaped feature makes it possible to maintain the assembly type three-dimensional structure which is not twisted or bent by an external force. I can. Moreover, since the connecting portion is not exposed to the outside, the appearance is excellent.
