<P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a reinforcing fitting that can be manufactured easily and can exhibit earthquake-resisting performance without damaging a structural material. <P>SOLUTION: A manufacturing method for a reinforcing fitting comprises a step of forming a V-shaped cutout part expanding toward one long side of mutually opposing long sides with a bent line C set in a strip-like plate 130 as a start point and a circular hole 13C provided continuously with the cutout part, a step of forming a channel member 13 having two webs 131, 132 by folding the strip-like plate 130 in a L-shape along the bent line C, and a step of folding in a L-shape the channel member 13 along the line segment orthogonal to the bent line C and passing through the center of the cutout part and the circular hole 13C, and welding each cutout edge part 13A composing the cutout part while making each cutout edge part 13A opposed to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
