Description

  The present invention relates to a structural material and a structure.

  Conventionally, as described in Patent Literature 1, a leg body is formed from a metal plate material, and reinforcing ribs are formed by bending both sides of the leg body. There is known a structural material including a leg having a first connection piece having a connection hole and a second connection piece having a second connection hole provided at the other end of the leg body. In addition, the document describes a structure in which four structural members are connected in a quadruped shape using bolts and nuts, and a plurality of these members are stacked and connected.

JP-A-2017-203290

  However, conventional structural materials and structures have room for improvement in the following points. That is, the conventional structural material is manufactured by bending a metal plate material. Therefore, in the structure using the conventional structural material, the fold in the structural material is conspicuous, and the viewer is likely to give a hard impression.

  In addition, when a structure is assembled using a conventional structural material, the first connecting pieces (second connecting pieces) included in each structural material are overlapped with each other and inserted into each first connecting hole (second connecting hole). The connection part is formed by fastening the nut to the bolt. That is, for example, in the example where the first connection pieces of the four structural members are overlapped with each other to form a connection portion, the four first connection pieces are stacked. Therefore, in the conventional structural material, the thickness of the connection portion in the structure tends to be large, and the appearance of the structure tends to deteriorate. Further, in the conventional structural material, it is necessary to connect the structural materials one by one at the time of assembling the structure, so that there is a limit in shortening the assembling time of the structure.

  The present invention has been made in view of such a problem, and it is possible to configure a structure that gives a soft impression to a viewer, to reduce the thickness of a connection portion in the structure, and to assemble the structure. It is an object of the present invention to provide a structural material that can easily reduce the length of the structure, and a structure using the same.

The connecting portion between the pair of pipe portions and the pair of end crushing portions is located outside the pair of pipe portions when viewed from a direction perpendicular to the second virtual plane. A bent structure material in which the pair of end crushing portions are arranged is referred to as a bent structure material.

A structure according to still another aspect of the present invention includes:
The central crushed portions of the pair of bent structural members are overlapped with each other, and a nut is fastened to a bolt inserted into each of the insertion holes of each of the overlapped central crushed portions, thereby forming an X-shape as a whole. Four configured X-shaped members,

  The structural material is integrally formed from a metal pipe material. Therefore, the structure made of the above-mentioned structural material tends to give a soft impression to the viewer due to the roundness of the pipe portion where the shape of the pipe material remains. Therefore, the structure made of the above structural material can be suitably used for decorative applications and the like.

  Further, when assembling a structure using the structural material, for example, the center crushed portions provided in each structural material, or, or end crushed portions, or the center crushed portion and the end crushed portion are overlapped, each A connection portion can be formed by inserting a bolt through the insertion hole and tightening with a nut. Therefore, according to the above-mentioned structural material, the overlap of each structural material at the connecting portion is reduced, the thickness of the connecting portion in the structure is reduced, and the appearance of the structure can be improved.

  Further, the structural material includes a pair of pipe portions. Therefore, it becomes possible to attach two pipe portions at a time by using one structural material. Therefore, according to the above-mentioned structural material, it is possible to further shorten the assembling time of the structure.

  Structures according to the other and still other aspects have the structural material. Therefore, a soft impression can be given to the viewer, the thickness of the connection portion can be reduced, and the assembling time can be easily reduced.
