Description

[Detailed Description of the Invention] The present invention relates to a beam-to-column joint fitting for joining a column and a beam, and aims to provide a beam-to-column joining fitting that facilitates joining work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The column-beam joint fitting of the present invention (hereinafter referred to as the joint fitting of the present invention) will be described below with reference to embodiments shown in the drawings.

Figures 1 to 4 show the joint fittings of the present invention,
The joining fitting 1 is a pipe material having a substantially square cross section, such as a square steel pipe.
It has a main body 4 having a predetermined upper and lower length, which is made by cutting two corner parts.

Therefore, although the main body 4 has four sides, the width of two of them is narrow.

A back plate 9 having a thickness approximately 2.5 times the thickness of the main body 4 is welded to the back surface of each of the four sides of the main body 4.

Each of the four sides of the main body 4 has a predetermined number of screw holes 7 (for example, two rows in the vertical direction on the wide side and one row in the vertical direction on the narrow side) on the main body 4 and the back plate 9 (however, (This includes cases where the thread is cut only on the back plate 9)
It is installed through the

On the other hand, the top plate 2, which is thicker than the main body 4, is welded to the upper end of the main body 4, and the bottom plate 3, which is thicker than the main body 4, is welded to the lower end.

A predetermined number of screw holes 7 are provided in each of the top plate 2 and the bottom plate 3.
will be provided.

Although the thickness of the back plate 9 is large, it is necessary to provide screw holes 7 in it to ensure a certain level of strength.On the other hand, the placement of the screw holes 7 in the top plate 2 and the screw holes 7 in the bottom plate 3 (near the outer periphery) (is desirable), so it cannot be made too thick.

Therefore, in the present invention, the thickness of the back plate 9 is set to be in the range of 2.0 to 3.0 times the thickness of the main body 4.

Next, it is desirable for the screw holes 7 of the top plate 2 to be as close to the outer periphery as possible, but since the planar shape of the top plate 2 is inevitably narrower than the surface of the main body 4, and the back plate 9 is added to the main body 4, the arrangement is as follows. It is devised as follows.

In other words, the screw holes 7 of the top plate 2 are arranged very close to the back plate 9 of the main body 4 without hitting the inner surface thereof.

Such ideas regarding the screw holes 7 of the top plate 2 are also applied to the bottom plate 3.

An example of how to use the joint fitting of the present invention shown in the above embodiments will now be described with reference to FIG. 4.

That is, the joining fitting 1 is installed between the pillar 12 on the first floor and the pillar 10 on the second floor.

The pillars 12 on the first floor are made of square steel pipes, and a connector 14 having a substantially cross-shaped cross section is welded to the top.

The joining metal fitting 1 is placed on the connecting plate 15 of the connecting tool 14 at the bottom plate 3, and the connecting plate 15 and the bottom plate 3 pass through a hole (not shown) in the connecting plate 15 and a bolt is screwed into the screw hole 7 of the bottom plate 3. 25 (2 pieces).

On the other hand, the pillars 10 on the second floor are also made of rectangular steel pipes, and are joined to the top plate 2 of the joint fitting 1 by bolts 25 (two pieces) using connectors 14, similar to the pillars 12 on the first floor.

Next, a beam 16 is shown, which is made of H-beam steel and has an end plate 18 welded to its end.

The end plate 18 is connected to the joint metal fitting 1 by a bolt 25 that passes through the hole 19 of the end plate 18 and is screwed into the threaded hole 7 of the main body 4 while the end plate 18 is in contact with the wide side of the main body 4 of the joint metal fitting 1. That will happen.

Next, the beam 20 is made of channel steel and is joined to the narrow side of the main body 4 of the joining fitting 1 in the same manner as described above.

Next, FIG. 5 shows a column 27 with a different cross-sectional shape from the above-mentioned one as another example of the use of the joint fitting of the present invention.
28 is shown.

The column-beam joint fitting of the present invention has the following effects in the configuration and usage method shown in the above embodiments.

(1) The column-beam joint fitting of the present invention has the structure described in the claims for utility model registration.In particular, the main body 4 is made by cutting one corner of a tube with a substantially square cross-section, so the wall surface thickness is This is extremely suitable for reducing the width (therefore using a beam 20 with a narrow width).

(2) The column-beam joint fittings of the present invention have the same configuration as above,
In particular, the top plate 2 and bottom plate 3 are welded to the upper and lower ends of the main body 4, and the top plate 2 and bottom plate 3 are thicker than the main body 4, so that they have sufficient strength without reinforcement.

(3) The column-beam joint fittings of the present invention have the same configuration as above,
In particular, the thickness of the back plate 9 is 2.0 to 3.0 of the thickness of the main body 4.
Since the area is doubled, the strength of the screw hole 7 provided therein is ensured, while there is no risk that the screw hole 7 of the top plate 2 and the screw hole 7 of the bottom plate 3 will be too close to the center.

(4) The column-beam joint fitting of the present invention has the same configuration as above,
In particular, the screw holes 7 of the top plate 2 and the bottom plate 3 are arranged at positions extremely close to the inner surface of the back plate 9 of the main body 4 without hitting the inner surface of the back plate 9, so that the columns 10, 12, 2
Sufficient bonding strength with 7 and 28 is ensured.
