[0002]

2. Description of the Related Art Conventionally, a building member is joined to another building member by using a fixing tool such as a bolt or a screw.

In particular, since the load-bearing frame is made of metal and each member of the load-bearing frame is formed of a thick steel material such as a steel pipe, the wall plate can be fixed on site by screwing or nailing. Therefore, the auxiliary base material that can be screwed or nailed is attached to the member made of steel pipe of the load-bearing frame with bolts, and the wall base plate is attached to the load-bearing frame with the bolts in contact with the load-bearing frame. The wall was fixed with screws or nails.

As described above, in the conventional example, it is necessary to attach the auxiliary base material with bolts, and there is a problem that the attaching operation is troublesome and takes a long time. Will be installed with bolts while the auxiliary base material is slanted along the diagonal material, and the work of attaching the wall board to the diagonally mounted auxiliary base material by screwing or nailing is done with screws from the surface side of the wall board There is a problem that it is difficult to confirm the position of the auxiliary base material for driving or nailing.

Also, as shown in FIG. 3B, the angle of the diagonal member 16 of the load-bearing frame 10 (which becomes one of the building members 7) and the auxiliary base bar 11 (which becomes the other building member 7). In the case of holding and joining (in the case of joining the auxiliary base bar 11 perpendicularly to the diagonal member 16 in the figure), the joint piece 3 of the present invention does not protrude the side piece 2 at the bendable portion 9 in the center of the bottom piece 1. Fig. 2
As shown in FIG. 2C, two continuous bending halves 6 are formed integrally with the foldable portion 9 as a boundary, and the load-bearing frame 10 is disposed between the two side pieces 2 of one of the bending halves 6 of the metal joint 3. Is inserted between the two pieces 2 of the other bent half portion 6 and the auxiliary base bar 11 is inserted between the two pieces 2 of the other bent half 6 so as to be elastically held by the two pieces 2. Then, the bearing frame 10 is formed using the joint hardware 3.
The auxiliary base bar 11 is joined to the diagonal member 16 at an angle.

FIG. 3 shows an example in which the metal joint 3 is bent by 90 ° or more to the side where the side piece 2 does not protrude in the bendable portion 9 at the center of the bottom piece 1, and the auxiliary base bar 11 is joined to the diagonal member 16. However, as shown in FIG. 4, as shown in FIG.
May be joined together, and as shown in FIG.
May be bent at a right angle to join the auxiliary base bar 11 at a right angle to the horizontal or vertical frame member 15.

As described above, the auxiliary base bar 11 capable of being screwed or nailed is attached to the load-bearing frame 10 by using the joint hardware 3, and in this state, the wall plate 14 constituting the wall surface is attached to the outer surface of the load-bearing frame 10. And a fastener 17 such as a screw or a nail is driven from the wall plate 14 to fix the wall plate 14. Here, the auxiliary base bar 11 is a bearing frame 1
The auxiliary base bar 11 is firmly fixed without being displaced by screwing or nailing the wall plate 14 to the auxiliary base bar 11 even though the auxiliary base bar 11 is fixed to the auxiliary base bar 3 only by being clamped by the joint hardware 3. Will be done.

In the above-described embodiment, an example is shown in which the auxiliary base bar 11 is joined to the load-bearing frame 10 with the joining hardware 3. However, the present invention is not limited to this example. Similarly, they can be joined back-to-back or at different angles with a single touch.

Further, the building member 7 can be joined to the flat mounting surface 8 by using the joining hardware 3. In this case, the surface of the bottom piece 1 of the joint piece 3 on which the side piece 2 does not protrude is attached to the flat mounting surface 8 without bending the joint piece 3 and, as shown in FIG. The end of the member 7, for example, the end of the partition member 18 can be fitted and joined by elastically sandwiching the two pieces 2.

Here, it is preferable to provide an adhesive portion 5 on the surface of the bottom piece 1 of the metal joint 3 opposite to the surface on which the side piece 2 protrudes (the side on which the side piece 2 does not protrude). In providing the adhesive portion 5, it can be provided by attaching one side of the double-sided adhesive tape to the bottom piece 1. When the adhesive portion 5 is provided in this manner, the bottom piece 1 can be adhered to the flat mounting surface 8 by the adhesive portion 5, and the metal fitting 3 is bent 180 ° to make the bottom piece 1 back to back as described above. When used, the adhesive portion 5 can be kept in a back-to-back state by bonding.
