As shown in FIGS. 1 to 4, a substantially square end plate (13) is attached by welding or the like to the joining side end which is the lower end of one of the pillars (10). A spacer (14) having a substantially cross-shaped cross section extending along the column axis direction (vertical direction) is attached to the end plate (13) by welding or the like, and the end plate (1) is attached to the tip of the spacer (14).
Substantially square joining plate (15) facing the 3)
Are attached by welding or the like. These end plates (13), spacers (14) and joining plates (15) are pillar materials.
It is within the range of the column cross-section so that it does not project laterally from the side surface of (10).

The joining plate (15) is divided into four by the four vertical pieces (16) (16) of the spacer (14).
Bolt insertion holes (17) (17) ... Are formed at the respective positions.

A substantially square end plate (20) is attached by welding or the like to the joining side end which is the upper end of the other pillar (11) in the same manner as the one pillar (10). . A spacer (21) having a substantially cross-shaped cross section extending along the column axis direction (vertical direction) is attached to this end plate (20) by welding or the like, and the end plate of the spacer (21) has an end plate.
(20) so that it faces the square plate (2).
2) is attached by welding or the like. The end plate (20), the spacer (21), and the joining plate (22) are within the range of the column cross section so as not to project laterally from the side surface of the column member (11).

The joining plate (22) is divided into four by the four vertical pieces (23) (23) of the spacer (21).
Bolt insertion holes (24), (24) ... Are formed at the respective locations.

The column members (10) and (11) are pin-joined to each other by stacking the joining plates (15) and (22) on each other and bolting them together. Specifically, the joining plates (15) (22)
Align the bolt insertion holes (17) (24)… of
The four bolts (30) (3), which are obtained by overlapping the joining plates (15) (22) and inserting them into the corresponding bolt insertion holes (17) (24).
The nuts (31) (31) are screwed onto the tips of 0) and tightened.

In this bolt joining work, the gap between the joining plate (22) and the end plate (20) formed by the spacer (21) on the side of the other pillar (11) is utilized to make this gap. From bolts (30) (30)… to bolt insertion holes (17) (24)
I'm trying to insert it in ... Further, as shown in FIG. 4, by utilizing the gap between the end plate (13) formed by the spacer (14) on the side of the one pillar (10) and the joining plate (15), Insert a jig (32) such as a wrench,
The nuts (31) (31) ... screwed onto the tips of the bolts (30) (30) ... are tightened.

As described above, since the pillar body (9) is constructed by extending the pillar materials (10) and (11), a platform construction method is adopted in which the steel frame, floor and outer wall are constructed for each floor. It is possible to realize a safe construction system. Moreover, an anchor or the like is not required during transportation, and the truck can be small in size, so that transportation efficiency can be improved.
In addition, since it is not necessary to bring extra construction members several days ahead to the site, deterioration and damage of the construction members due to rust etc. of the construction members can be reduced, and construction on narrow land becomes easy. Further, it is not necessary to secure a wide storage space like the case of a through pillar, and the on-site management can be simplified.

Also, in this pillar (9), four bolts (3
Since the pillars (10) and (11) are pin-joined using 0) (30) ..., the workability is significantly improved compared to the conventional rigid joining of pillars. It is possible to improve the cost and reduce the cost. Moreover, since the pin joining positions of the pillar members (10) and (11) are the inflection points located in the central portion of the second floor, the rigidity is not greatly affected.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention.

[0018]

As is apparent from the above description, the columnar body of the present invention has a structure in which the columnar members are pin-joined to each other at the inflection point of the middle portion of the floor, so that the rigidity of the columnar body is improved. The number of bolts to be used can be reduced and the pillar members can be easily added without causing any trouble. For this reason, compared with the conventional method of rigidly joining pillar materials,
The workability can be significantly improved and the cost can be reduced.

Moreover, since the joint plates are attached to the joint-side ends of the respective pillar members through the spacers having a substantially cross-shaped cross section, and these joint plates are superposed on each other and bolt-joined, the gap formed by the spacers is eliminated. By utilizing this, it is possible to easily perform the work of inserting the bolt into the bolt insertion hole and the work of tightening the nut screwed at the tip of the bolt, and it is possible to further improve the workability.
