Grooves 9 and 10 cut out along the portion 4 are formed. Deformation portions 9b are respectively formed on portions of the inner side surfaces 9a, 10a of the grooves 9, 10. The tip of the deformed portion 9b projects outward from the outer peripheral surface 4a of the bent portion 4. Further, the tip of each deformed portion 9b is connected to the outer surface 2 of the non-welded piece 2.
It extends almost on the same plane as a.

A method for manufacturing the bracket will be described. Figure
As shown by a two-dot chain line in FIG. 3 (a) , grooves 9 and 10 are punched in the plate-shaped bracket body 1 by a press machine. Then, the angle of the inner surface of the bracket body 1 in the drawing direction of the arrow by a press machine and a non-welded piece 2 and the welding strips 3 are bent around the bent portion 4 so that Do perpendicular. Along with this, a part of the inner surfaces 9a, 10a of the grooves 9, 10 is torsionally deformed to form a deformed portion 9b, and the deformed portion 9b projects outward from the outer peripheral surface 4a of the bent portion 4.

Next, the operation and effect of the bracket configured as described above will be described. A method of welding the bracket body 1 configured as described above to the column 8 will be described.
As shown in FIG. 4, the welding piece 3 of the bracket body 1 is
At a predetermined position on the flange of the column 8 so that the non-welded piece 2 stands upright with respect to the flange of the column 8. In the welding posture of the bracket main body 1, the center of gravity of the bracket main body 1 is located closer to the non-welded piece 2. Therefore, the bracket body 1 is in a state where it is easy to fall in the direction opposite to the arrow shown in FIG. However, since the non-welded pieces 2 are supported by the columns 8 by the deformed portions 9b formed on the inner side surfaces 9a, 10a of the grooves 9, 10, the posture of the bracket body 1 is stabilized. Next, both the groove portions 9 and 10 are fillet welded, and the bracket body 1 and the column 8 are temporarily joined. Subsequently, joining is performed by fillet welding along one short piece direction edge of the welding piece 3, and then the bracket body 1 and the column 8 are joined by fillet welding along the other short piece direction edge. .

The bracket body 1 can be welded to the column 8 in a stable welding position.

When the bracket body 1 is manufactured, it is only necessary to bend the bracket body 1 after forming the grooves 9 and 10. For this reason, the existing equipment can be used for manufacturing the bracket main body 1, and no extra equipment such as a mold is required. Therefore, an increase in the cost of the product can be prevented.

Further, when the bracket body 1 is welded to the column 8, the bracket body 1 and the column 8 can be temporarily joined by performing fillet welding on both the grooves 9, 10, so that one of the welding pieces 3 can be welded. When the fillet welding is performed along the short edge in the short piece direction, the edge of the other welding piece 3 can be prevented from floating. For this reason, it is possible to reliably prevent an error in the joining position of the bracket body 1.

It should be noted that the present invention is not limited to the above embodiment, and may be made as follows without departing from the spirit of the present invention. (1) In the above embodiment, the bracket main body 1 is joined to the column 8. However, in order to attach a purlin or the like to the bracket main body 1, the bracket main body 1 may be joined to a roof beam other than the column by welding.
