DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a column and a beam of a steel structure.

[0002]

2. Description of the Related Art As shown in FIGS. 5 and 6, a method of connecting a column 1 consisting of a square pipe and a beam 2 made of H-section steel is as follows. The same diameter and thicker prism segment 1a is welded, and H
The connection bracket 1c made of a section steel is welded, and the upper and lower iron plates 3, 3 are fastened to the connection bracket 1c with bolts 4, so that the beam 2 is connected. In the figure,
Symbols A and B are welds.

Further, as shown in FIG. 7, a prismatic segment 1a provided with a tapped hole is directly welded to a predetermined portion of a pillar 1, and a flange 2c welded to the tip of a beam 2 of H-section steel is attached to the segment 1a. May be fastened with bolts 2d.

[0004]

In any of the above joining methods, first, it is necessary to fix the segment 1a in the middle of the column 1 by welding, so that the working efficiency is low, the cost is high, and the strength is low. is there.

An object of the present invention is to provide a coupling structure which is advantageous in cost and excellent in strength.

[0006]

In order to solve the above-mentioned problems, a connecting structure according to the present invention comprises a square pipe-like column into which a prism segment is press-fitted so as to be inscribed at a predetermined position, and a beam provided with a flange at an end. , Said prism segment is a square pipe-shaped column
A tap hole is formed directly on the side wall with a wall thickness, and a bolt inserted through the flange and the peripheral wall of the square pipe is screwed into the tap hole and fastened, and the peripheral wall of the square pipe is formed by the prism segment and the flange. It was pinched.

[0007]

Since the prismatic segments are press-fitted into the square pipe-like columns, the joints of the beams are formed without welding.

Since the peripheral wall of the square pipe is sandwiched between the prism segments and the flanges of the beams, the coupling strength between the columns and the beams is large.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, first, a prism segment 20 having an outer diameter capable of being press-fitted into the inner diameter of the square pipe is press-fitted into a predetermined portion of a column 10 formed of a square pipe.

At the press-fitting point, a bolt insertion hole 11 penetrating into the pillar 10 is provided in advance.

The segment 20 has a side wall.
Are provided with tap holes 21 directly . This segment 20
It is preferable to use a material thicker than the pillar 10.

The segment 20 is positioned such that the through hole 11 of the column 10 and the tap hole 21 of the segment 20 coincide with each other.
Press-fit. Note that the press-fitting strength is the same as that of the segment 20.
It is sufficient that this position can be maintained, and if necessary, it may be temporarily fastened with bolts in the state of FIG.

Next, as shown in FIGS. 3 and 4, a bolt 32 is inserted into a flange 31 fixed to an end of a beam 30 and a through hole 11 of the column 10 at a construction site or the like. Screw in and fasten. As a result, the peripheral wall of the pillar 10 made of a square pipe is
The flanges 31 are strongly clamped, and a sufficient bonding strength can be obtained.

[0015]

According to the present invention, as described above, a prism segment is press-fitted into a column made of a square pipe, and the segment and the flange of the beam are bolted to join the column and the beam. There is no need to weld the prism segment to the pipe and it is only press-fitted, so the work efficiency is good, and the column is not divided and used as an integral unit, so it has excellent strength, and the prism column segment and the flange of the beam provide the corner of the column. Since the pipe is strongly clamped, a sufficient bonding strength can be obtained.
