However, in the joining of the structural members 2 as described above, the abutting portion (indicated by X in FIG. 14) of the portion inclined at 45 degrees is not directly joined, and the joining strength is weak. In addition, since the L-shaped connection fitting 40 is fixed to the structural material with the screw tool 41, there is a problem that the head of the screw tool 41 is exposed on the outer surface of the structural material 2.
Even if an attempt is made to join another structural material to the joint portion between the structural materials 2 connected in this way, there is a problem that the screw tool 41 and the L-shaped connecting fitting 40 become an obstacle.

In addition, the ends of structural materials such as C-channels and square steel pipes are also joined directly by welding. However, if the ends of a long structural material are butted against each other and directly welded, the construction accuracy is poor, and there are problems in terms of cost and yield strength. Especially when the abutting parts of structural materials such as C-channels and square steel pipes are slightly displaced in the width direction,
There is a problem that the contact area of the butted portions becomes small and the bonding strength is not stable. Furthermore, even if the structural frame of the wall panel is formed in the factory by combining the structural materials, if welding is performed when the structural frames of the wall panels are joined together, they will be on-site construction. There are more problems in terms of sex.

The structural member 2 is a long member made of steel such as a square steel pipe having a quadrangular cross section, a C-channel, and an H-shaped steel.
Is cut at 45 degrees to the longitudinal direction. Then, one of the two surfaces sandwiching the right angle of the metal joint 1 is brought into contact with the end of the structural member 2 cut at 45 degrees, and is fixed by a fixing means such as welding. Here, when the joining metal piece 1 is brought into contact with the end of the structural material 2 which is a vertical material or a horizontal material and is fixed by welding or the like, the remaining one surface of the three surfaces of the joining metal material 1 other than the two surfaces sandwiching the right angle Are horizontal or vertical and are fixed so as to be flush or nearly flush with the outer surface of the structural material 2. When the weld metal 1 is brought into contact with and welded to the end of the structural material 2 such as a square steel pipe, C channel, or H-shaped steel cut at 45 °, the welded face of the weld metal 1 is inclined at 45 ° and welded. Therefore, the contact area with the cut end of the structural material 2 such as the square steel pipe, the C channel, and the H steel can be reliably ensured, and reliable welding can be performed. In this way, by fixing the metal joint 1 to the end of the structural material 2 that is a vertical material or a horizontal material, the surface of the two surfaces sandwiching the right angle of the metal joint 1 that is not fixed to the structural material 2 becomes vertical. On the other hand, the slope 3 is inclined at 45 degrees.

As described above, in order to join the structural material 2 having the joining metal piece 1 at the end, the structural material 2 is joined at a right angle and the structural materials 2 are joined in a straight line in the horizontal or vertical direction. There are cases.
