Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valley for a metal roof.

[0002]

2. Description of the Related Art In a conventional valley-filling structure, the center of a rectangular metal plate is shallowly folded in a valley 11, the middle portion between both side ends is folded upward twice twice in the opposite direction, and a tip 13 is extended outward. The side edge 15 of the roof plate 14 which is bent downward is engaged with the intermediate folded portion (FIG. 5).

[0003]

In the conventional valley-filled structure, the upper roof plate 14 of the goby-folded portion of the roof comes into close contact with the tip 13 of the valley-fill, and the intrusion B of rainwater from the valley is caused by capillary action. There is a risk of transmission to the purlin 16 beyond the tip 13 of the valley, and the effect of the valley may not be sufficiently achieved.

[0004] Further, since the folding process is performed twice at the intermediate portion, it is difficult to manufacture.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention is constructed so that a space is created without an engaging portion between a shingle and a valley close to each other, thereby preventing a capillary phenomenon.

[0006] For this purpose, the valley of the present invention is folded once on both sides and further folded back to form a stepped structure by further folding the double folded portion, so that the valley is fitted when the roof plate is engaged. It was formed so as not to adhere. In addition, since it is only folded twice in the same direction, the folding process is simple and easy.

[0007] Furthermore, by engaging the suspension with the second turn-up portion, the step can be further raised, a higher space can be created, and the intrusion of rainwater can be completely prevented.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a description will be given according to an embodiment shown in the drawings.

FIG. 1 shows the folding process. First, both sides of the rectangular plate are folded upward (b), and the double sides 2 are folded upward (b). Then, the center 3 is shallowly folded in valleys to complete the valley. The angle of this valley fold is
Determined according to the roof slope on both sides.

FIG. 2 is a partially enlarged view showing a construction state, in which a suspension 5 is fixed to a purlin 6 and a tip engaging portion 7 is engaged with the double bent end 2 of the valley. A goby fold 8 to the underside of the shingle 4 engages the end 1 of the valley.

FIG. 3 shows an upwardly projecting portion 9 formed at the center of the valley fold portion of the valley, and FIG. 4 shows a flat portion 10 formed at the center of the valley fold portion.

[0012]

According to the valley-mounted structure of the present invention, it can be completed easily by turning it twice, so that it is easy to manufacture.
Since the space A is formed between the valley and the first folded end 1, for example, even if the rainwater C enters from the valley, the capillary phenomenon is blocked by the space A and the space D in the direction of the main house 6 is reached. It does not reach and there is no worry about rain leaks.

Also, by forming the valley portion as shown in FIG. 3 or FIG. 4, the rainwater flowing on the slope becomes a rapid current and collides from both sides, stays in the valley portion, and stays in the valley. This is advantageous because it can flow down the roof smoothly, that is, in the direction of the eaves, without intrusion.

Claims (2)

(57) [Claims] After forming a mountain-folded portion in the center of a rectangular metal plate, both sides thereof are shallowly valley-folded to form a W-shaped cross section, and both sides are folded upward by a small length, and further double-sided both sides Is folded shorter than the folded length to form a valley, and a valley for a metal roof is formed so that a side edge of a metal roof slab that is bent downward is engaged with the first folded tip in the inward direction. Construction. 2. After forming the center of a rectangular metal plate in a flat portion, the two sides are shallowly valley-folded, and both sides are folded upward by a small length. A valley-filling structure for a metal roof, wherein the folds are folded short to form a valley, and the side edge of the metal roof slab that is goby-folded downward is engaged with the first folded tip inward.
