FIG. 5 shows a method of using the pillar 11 according to the present invention. In other words, as shown in FIG.
The column material 11 is disposed between the upper and lower beams, and the upper column material mounting plate 16 is brought into contact with the lower surface of the flange 2 a of the upper beam member 2. The bolt 10 is brought into contact with the upper surface of the flange 3a, and the bolt 10 is inserted into the bolt hole 16a of the column member mounting plate 16 and the bolt holes (not shown) of the beam members 2 and 3 using the respective bolt attaching / detaching spaces 15. And fastened with a nut (not shown). In this case, a spacer (not shown) having a required thickness may be interposed between each column mounting plate 16 and the flange 3a of each beam 2,3.

In this pillar 11, since each bolt attaching / detaching space 15 is formed on an extension of the corner b of the pillar main body 12, see FIG. 2, FIG. 3 and FIG. As can be seen, when the column material mounting plate 16 is attached to each of the beams 2 and 3 made of H-section steel, the web 2 of the beams 2 and 3 is used.
The two bolt mounting / demounting spaces 15 are located on both front and rear sides with respect to the b and 3b, respectively.
Can be used. Incidentally, if each bolt attaching / detaching space portion 15 is formed on an extension of the flat wall portion a of the column member main body 12, two bolt attaching / detaching portions along the webs 2b, 3b of the beam members 2, 3 are provided. Since the space portion 15 is located, only one bolt attaching / detaching space portion 15 is located on each of the front and rear sides of the webs 2b and 3b.
The bolt 10 cannot be used in the two bolt attaching / detaching spaces 15 located along the line b.

In addition, since the upper and lower hollow crushing shaft portions 14 of the pillar main body 12 are formed in a substantially cross-shaped cross section, the pillar 11 is resistant to compression and tension, and has sufficient mechanical strength. Particularly, it is optimal when the length of the hollow crushed shaft portion 14 is relatively short.

In the column member 11 of the embodiment described above, the hollow crush shaft portions 14 are formed at the upper and lower ends of the column main body 12.
May be formed either above or below.

A column having a bolt mounting / removing space formed on the outer periphery of the crushed shaft, and having a bolt hole at an end surface of the crushing shaft at a position corresponding to the bolt mounting / removing space. Since the material mounting plate is fixed, the number of members is smaller than that of this type of conventional building column material, the angle of the welding seat plate and the angle material for forming the bolt attachment / detachment space can be omitted, and the column material can be easily manufactured. In addition, the accuracy can be improved, and the cost can be reduced.

The crushing shaft is formed in a hollow shape, and the column mounting plate is provided with a drain hole so as to communicate with the hollow portion of the hollow crushing shaft. When the material is immersed in the treatment tank to perform plating or electrodeposition coating, the treatment liquid flows from the drain hole into the inside of the pillar body through the hollow portion of the hollow crushed shaft portion, whereby the pillar material is removed from the treatment tank. It sinks without floating inside, and can be subjected to a desired plating treatment. In addition, since the treatment liquid can flow into the interior of the pillar body, the inner surface of the pillar body is also subjected to a treatment such as plating to prevent internal corrosion.

According to the second aspect, since the hollow crushing shaft-shaped portion is formed in a substantially cross-sectional shape comprising four ridges,
It is resistant to compression and tension, has sufficient mechanical strength, and is particularly effective when the length of the hollow crushed shaft is relatively short.

According to the third aspect of the present invention, four pillars are formed so as to extend over the extension of the flat wall portion of the pillar body composed of the flat wall portion and the corner portion, and each bolt mounting / dismounting space is provided. Since the portion is formed on the extension line of each corner, when the column mounting plate is mounted on the flange of the beam made of H-section steel, two bolts are respectively provided on both front and rear sides of the web of the beam. The mounting / dismounting space portion is located, so that two bolts can be used on two opposite sides of the column mounting plate, whereby the column can be properly bolted to the beam.

According to the fourth aspect, each ridge is formed to have a substantially U-shaped cross section, and the inside of the U-shaped ridge communicates with the hollow portion of the hollow crushed shaft. Therefore, the processing liquid infiltrates into each ridge, and the entire inner surface of the ridge is treated. Therefore, the entire inner and outer surfaces of the pillar can be completely plated or electrodeposited.
