BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a draining material for a corner corner used for applying a metal siding material or the like to the exterior of a house and a method of manufacturing the same.

[0002]

2. Description of the Related Art When constructing a metal siding material on the outer wall of a building, a draining material is hit on the base of the building, and a metal siding material is adhered thereon. The draining material 1 is as shown in FIG. In this case, a metal band is bent into a hat shape, and flanges 3 and 3a project from both sides of the opening of the groove 2. This drainer 1 is long and is cut in accordance with the length of the straight section of the building, so that the corners of the building are exposed at the corners, and rainwater may enter the base. , Or the appearance is reduced.

[0003] Therefore, in the corner of the building, a contractor prepares a draining material for the corner of the corner on site, and the corner of the corner of the corner is formed.
Attached to the This drain corner corner drainer 4
The draining material 1 is cut to an appropriate length, and each side wall 5, 5 on both sides of the groove 2 of the draining material 1 is cut with scissors as shown in FIG.
a, V-shaped cuts 6 and 6a each having an inner angle of about 90 ° that are enlarged in the direction of the opening of the groove 2 are provided so as to be symmetrical with respect to the center plane of the groove 2; The respective V-shaped cuts 6, 6 are formed in the flange portions 3, 3a.

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.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a draining material for a corner corner which solves these problems and a method for producing the same.

[0006]

According to the first aspect of the present invention, a drainer for a first corner corner is formed on each side wall on both sides of a groove of a hat-shaped bent material of an embossed metal band with an inner angle enlarged in a direction of an opening of the groove. 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.
A bent groove for bending the bottom wall reaching the apex of the V-shaped cut.

[0007] The draining material for the second corner corner may be formed by cutting one side edge of the above-mentioned draining material, which is separated by a parallel cut of a flange portion continuous with one side wall of the groove provided with the first overlapping portion. A second overlapped portion is provided by projecting in a parallel cut away from the first overlapped portion.

[0008] Further, the production of each of the above-mentioned drainers is carried out by forming a parallel notch having a bar extending on one side in the width direction of the embossed metal band in a direction perpendicular to the center from the edge and extending in the longitudinal direction on the way, Part side is continuous with the parallel cut,
And an inner angle of about 4 having a maximum opening narrower than the parallel cut.
Forming a first notch having a 5 ° V-shaped notch, and a parallel notch extending perpendicular to the center direction from the edge on the side opposite to the metal band width direction, and a maximum opening side continuous with the parallel notch; And a second notch having a maximum opening having a V-shaped notch having an inner angle of about 90 ° substantially equal to the parallel notch, and vertices of the V-shaped notch having an inner angle of about 90 ° and 45 ° are opposed to each other. After that, it is rolled into a hat shape by roll forming so that the V-shaped cuts of about 90 ° and 45 ° are located on both side walls of the groove, and then about 90 ° of the inner angle of the groove bottom wall. A folded groove is formed at a position where the vertices of the V-shaped cuts at 45 ° and 45 ° face each other.

[0009]

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.

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.

[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.

In the manufacturing method, a metal band is first provided with a V-shaped cut and a parallel cut, and then, the roll is formed into a hat shape by roll forming. 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.
