Alternatively, the specific diaphragm portion 11 and the wooden beam 2Z may be joined with a drift pin or the like. For example, when joining with a bolt and nut or a drift pin, a specific diaphragm portion 11 is formed with a through hole 11H.
Also, the other diaphragm portion 12 and the metal beam 1Z may be joined by welding or by bolts and nuts.
According to Embodiment 2, it is possible to provide the metallic column 1 that can expand the applications of the diaphragm 10 .
Also, the wooden beams 2Z can be joined to the specific diaphragm portions 11, 11 which are formed to have a longer protruding length from the outer surface and a larger size than the other diaphragm portions 12, 12. Therefore, the joint strength between the wooden beam 2Z and the metallic column 1 can be improved, and the joint strength between the wooden beam 2Z and the metallic column 1 and the joint strength between the metallic beam 1Z and the metallic column 1 are This is preferable because the difference in bonding strength between the two can be reduced.
In addition, in Embodiment 2, the wooden wall material 2 may be joined instead of the wooden beam material 2Z.

The number of pin through-holes and bolt through-holes described above may be freely set according to the required strength, the number of drift pins, and the number of bolts.
Moreover, it is preferable to use a high-strength bolt (high-tension bolt) as the bolt described above.

Moreover, although an example of using a rectangular steel pipe as the metallic column 1 has been shown, the metallic column 1 may use a steel pipe having a triangular, circular, polygonal, or other cross section.

Further, although the wooden wall material 2 and the wooden beam material 2Z have been exemplified as wooden members, the wooden member may be, for example, a wooden floor material or other members.

The pillars of the present invention may be pillars made of other materials, such as wooden pillars, instead of metallic pillars.
That is, the column of the present invention is provided with a diaphragm protruding from the peripheral surface of the column, and is configured so that the shape of a part of the diaphragm protruding from the peripheral surface of the column is different from the shape of the other part, so that the diaphragm can be used. Any pillar that can be expanded is acceptable.

1 metallic column, 1a, 1b, 1c, 1d outer surface, 1Z metallic beam material,
2 wooden wall material (woody member), 2Z wooden beam material (woody member), 10 diaphragm,
11 specific diaphragm parts, 12 other diaphragm parts.

Claims (7)
