Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column in which a reinforcing metal can be efficiently inserted into the inner hole of a column base having a raised bead and the cost can be reduced.

[0002]

2. Description of the Related Art As shown in FIG. 10, a pillar of a house having a steel frame structure rigidly connecting a pillar and a beam shields a gap extending in the length direction of a roll-formed pillar base body a by welding. Therefore, a so-called bead b protruding from the inner surface of the pillar base a is provided on the inner surface of the pillar base a.

Further, when the reinforcing metal piece c is inserted into the inner hole of the pillar base body a at the beam connection position, conventionally, the back plate d of the reinforcing metal piece c is brought into contact with the inner surface of the pillar base body a.
The raised portion of the bead b is scraped off as shown in FIG.

[0004]

However, the bead b
Reinforcing metal c inserted into the inner hole of the pillar base body a
Since the directionality is not clear, the direction is often erroneous at the time of insertion, and it costs extra to scrape off the bead b, and it is troublesome.

The present invention is based on the fact that a vertical groove for loosely fitting a bead is provided in a back plate of a reinforcing metal article, so that the directionality of the reinforcing metal article can be clarified, and mistakes in the direction of insertion can be reduced. The purpose is to provide a pillar that does not need to scrape off the bead, which can reduce labor and cost.

[0006]

In order to achieve the above object, a pillar of the present invention is inserted in a tubular pillar base and a beam connecting position where a beam is connected to an inner hole of the pillar base and an outer surface of the pillar base. And a reinforcing metal member, wherein the reinforcing metal member is formed by connecting two or more back plates facing the inner surface of the pillar base member with a connecting member, and extends to the inner surface of the pillar base member in the longitudinal direction. A vertical groove in which a bead rising from the inner surface of the base body is loosely fitted is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 of the present invention pillar 1
Is a pillar base 2 made of a square steel tube having a rectangular cross section, and a beam H inserted in the inner hole 2a of the pillar base 2 and on the outer surface 2A of the pillar base 2.
And a reinforcing metal member 3 arranged at a beam connection position A to which is connected.

As shown in FIGS. 2 to 4, the reinforcing metal members 3 are two or more flat plate-shaped rectangular members facing the inner surface 2B of the columnar base 2 and in surface contact with the inner surface 2B. The four back plates 4 are arranged, and a flat plate-like connecting member 5 is fixed to the inner surface of the back plates 4 at approximately the middle position in the height direction to connect the back plates 4.

Of the four back plates 4 ... In this example, 1
A bead 6 extending in the lengthwise direction on one inner surface 2B of the pillar base 2 and rising from the inner surface 2B of the pillar base 2 on one back plate 4.
The vertical groove 7 that loosely fits is continuously recessed.

Therefore, the reinforcing metal member 3 is provided with the directionality by the vertical groove 7, and it is possible to prevent the direction of the reinforcing metal member 3 from being mistaken when it is inserted into the inner hole 2a of the column base 2.

Further, two reinforcing metal pieces 3 are arranged at the beam connection position A at the upper and lower sides, and a T-shape in which a horizontal mounting plate 20B is projected from a fixing plate 20A along the outer surface 2A of the column base 2. The fixed plate 20A of the fixed metal piece 20 is inserted into the holes 21 provided in the pillar base 2 and the through holes 22 of the back plate 4 arranged concentrically with the holes 21. Are attached to the outer surface 2A of the column base 2 by using bolts 24 ...

The reinforcing metal piece 3 is temporarily fixed in the inner hole 2a with a bolt before the pillar base body 2 is built, and the fixed metal piece 20 is temporarily fixed at this stage. May be fixed together with the reinforcing metal 3, or may be fixed after the pillar base 2 is built.

Further, between the mounting plates 20B and 20B of the upper and lower fixing hardware 20 and 20 fixed at the beam connection position A,
The end of the beam H made of, for example, I-shaped steel is inserted and bolted to the mounting plates 20B, 20B.

Further, the upper end of the uppermost beam H is, as shown in FIG. 1, a stigma plate 25 fixed to the upper end of the beam base 2.
It is bolted to the overhanging portion 25A.

As described above, the reinforcing metal member 3 can be inserted into the inner hole 2a of the pillar base 2 without scraping off the bead 6, and the pillar base 2 having a reduced cost can be used.

Further, giving the directionality to the reinforcing metal member 3 means that
Particularly, it is effective in clarifying the direction of insertion when the positions, sizes, etc. of the through holes 22 are different in each back plate 4.

As shown in FIG.
It is also possible to form it from the back plates 4 and 4 and the connecting member 5,
Further, two parallel back plates 4 and 4 may be connected by tubular connecting members 5 and 5 as shown in FIG.

Further, as shown in FIG. 7, a pipe member 27 through which long bolts 26 for fixing to the column base 2 pass is used as a connecting member 5 for connecting the two parallel back plates 4 and 4. Good.

Further, three back plates 4 can be provided in a U-shape in a plane. Even when two or three back plates 4 are provided, the vertical groove 7 can give directionality to the reinforcing metal member 3, and the pillar base 2
The direction at the time of insertion into the inner hole 2a can be clarified.

Further, as shown in FIGS. 8 and 9, the beads 6 may be provided on a plurality of inner surfaces 2B of the pillar base 2, and at this time, a plurality of back plates 4 corresponding to the beads 6 ... A vertical groove 7 in which the bead 6 is loosely fitted is recessed in.

[0021]

As described above, in the pillar of the present invention, the back plate of the reinforcing metal member is provided with the vertical groove in which the bead extending in the lengthwise direction on the inner surface of the pillar base body and which is raised from the inner surface of the pillar base body is recessed. . Therefore, the direction of the reinforcing metal object can be clarified by the back plate provided with the vertical groove, it is possible to prevent the reinforcing metal object from being inserted into the inner hole of the pillar base body in the wrong direction, and the bead loosely fitted in the vertical groove. Serves as a guide, and a reinforcing metal can be easily inserted.

Further, since the work of scraping off the bead can be eliminated, the labor can be remarkably reduced and the cost can be reduced.
