However, in recent years, the number of skilled sheet metal contractors has decreased, and there has been a problem that it is complicated to produce a drainer every time at a construction site. In addition, since the material metal band is formed by embossing, even if the side walls 4, 4a and the flange portions 3, 3a are manufactured so as to linearly abut each other, a gap is formed due to embossing irregularities. Then, the bottom wall 8 of the groove 2 is bent along irregularities and does not become straight. Therefore, there is a problem that rainwater infiltrates from the side wall 5 of the groove 2 on the upper side when the construction is performed, and the appearance is also inferior.

V-shaped cuts of about 90 ° are provided so as to be symmetrical with respect to the center plane of the groove, and parallel cuts having the same width as the maximum width of the V-shaped cuts are formed in the flanges on both sides of the opening of the groove. In the draining material provided so as to extend at right angles to the extending direction of the groove in a state continuous with the V-shaped notch, a V-shaped notch is formed in the V-shaped notch on one side edge separated by the V-shaped notch on one side wall of the groove. A first overlapping portion is provided by projecting until the interior angle becomes approximately 45 °, and another interior angle of approximately 90 ° from the apex of the V-shaped cut provided with the first overlapping portion in the groove bottom wall.

台部まで侵入することがない。The first drainer is formed by turning the bottom wall of the groove back at the groove and bending the flange to the flange side by about 90 ° to form a V having an inner angle of about 45 °.
It is used so that one side wall of the groove provided with the character-shaped cut is on the upper side. At the time of bending, the groove bottom wall is easy to bend along the return groove, so that the bending line is straight. Also, when bent, the V-shaped notch on one side wall of the groove has an inner angle of about 45 °, so the first overlapped portion overlaps with the side wall facing through the V-shaped notch,
Its edge extends to the groove bottom wall. In addition, when the first overlapping portion is positioned outside, it is possible to prevent rainwater from entering the inside, but it is preferable to be inside because the appearance is inferior. Even if they are overlapped inside, the drainage material applied to the base portion exists below the first overlapped portion, so that rainwater does not enter the base portion.

外問題がない。On the other hand, the edge of the side wall opposite to the groove portion separated by the V-shaped cut and the edge of the flange portion separated by the parallel cut are abutted in the same manner as in the prior art. Since the groove protrudes and becomes an eave, rainwater does not enter and is not visible in appearance. In addition, the flange on one side wall of the groove provided with a V-shaped notch having an inner angle of about 45 ° is mostly covered with a corner corner material which is usually used when a metal siding material is applied later. There is no problem except when the weather is extremely strong.

に強い場合でも雨水の侵入を防止できる。[0011] In the second drainer, the second overlapping portion provided on one side of the flange portion separated by the parallel cut is bent on the side opposite to the projecting side of the groove so that the bending line is substantially perpendicular to the direction in which the groove extends. After bending by about 90 °, the groove bottom wall is bent by about 90 ° toward the flange side as in the case of the first drainer. Due to this bending, the second overlapped portion is overlapped with the opposite edge which is opposed through the parallel cut, so that the second overlapped portion is formed.
If the overlapping portion is placed on the upper side, it is possible to prevent rainwater from entering even when the wind and rain is extremely strong.

The parallel cut has a width of 30 to 60 mm and a depth of 30 to 60 mm. Is as large as 50 to 100 mm, and the edges on both sides are likely to fluctuate up and down. For this reason, the rear edge in the molding direction may be displaced from the biting position of the molding roll during molding, and may collide with the molding roll and be damaged.
However, if the portions provided with the parallel cuts are connected by a bar, the rear edge is guided by the bar in the biting direction of the forming roll, so that the rear edge does not collide with the forming roll.

できる。As described above, the draining material for an out-of-corner corner according to the present invention is most affected by the wind and rain. Since the first overlapping portion is provided on the side wall to form an overlapping structure, water tightness is high. Also, a second overlapping portion is provided on the upper flange portion, which has a butt structure as in the past,
The watertightness is even higher due to the superposed structure. Further, in the case where a cut is provided in the metal band in advance, and then the draining material is manufactured by roll forming, if the edges on both sides of the cut are connected by a bar, the edge of the cut can be prevented from being damaged.
