Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure for constructing a valley portion of a roof by using a valley water receiving member.

[Prior Art] Conventionally, when constructing a valley portion of a roof, as shown in Fig. 4, a valley water receiving member 2'having a substantially V-shaped cross section is arranged along a base 1 of the valley portion of the roof, and The ends of the roofed roof tiles 3 were placed on the upper surfaces of both sides of the valley water receiving member 2 '.

[Problems to be Solved by the Invention] By the way, when the valley is constructed as described above, there is a problem that the wood mouth of the end of the roof tile 3 is visible in the valley and the appearance is poor.

The present invention has been made in view of the points described above, and the object of the present invention is to construct the roof tiles so that the mouth of the end of the roof tile cannot be seen even in the valley, and the end of the roof tile cannot be seen. The purpose is to provide a structure for the roof valley that can respond to changes in the roof slope.

[Means for Solving the Problems] In order to achieve the above object, the structure of the valley portion of the roof of the present invention is
An upper surface piece 2a having a substantially V-shaped cross section, a folding piece 2b folded back from both ends of the upper surface piece 2a, a hanging piece 2c hanging downward from the end of the folding piece 2b, and an upper surface piece 2a from the lower end of the hanging piece 2c. The valley water receiving member 2 made of a metal plate is formed with the bottom piece 2d extending outward so as to be substantially parallel, and the inclination of the folding piece 2b is made steeper than the inclination of the top piece 2a and the bottom piece 2d. The valley water receiving member 2 is arranged along the valley portion of the roof, the bottom piece 2d is placed on the base 1 of the valley portion of the roof, and the end of the roof tile 3 roofed on the roof is used as the folded piece 2b of the valley water receiving member 2. It was fitted between the bottom piece 2d.

[Operation] The end of the roof tile 3 can be fitted between the folded piece 2b and the bottom piece 2d of the valley water receiving member 2 so that the end of the roof tile 3 cannot be seen in appearance, and the folded piece 2b and the bottom piece can also be seen. The 2d can be bent so that it can respond even if the roof slope changes.

[Example] As shown in FIG. 1, a base 1 of a roof is formed by laminating a base plate 1b on a rafter 1a, and a roof base waterproof sheet 5 such as a synthetic resin sheet is formed on the base plate 1b. Is laid all over. As shown in FIG. 2, the valley water receiving member 2 has a substantially V-shaped upper surface piece 2a having an upper surface, a folding piece 2b folded from both ends of the upper surface piece 2a, and a downward portion hanging from the end of the folding piece 2b. It is composed of a hanging piece 2c and a bottom piece 2d extending outward from the lower end of the hanging piece 2c so as to be substantially parallel to the upper surface piece 2a,
It is integrally formed of a metal plate such as a copper plate, an iron plate, and a stainless steel plate. The return piece 2b of the valley water receiving member 2 is steeper than the inclination of the top piece 2a and the bottom piece 2d, and the gap between the return piece 2b and the bottom piece 2d becomes narrower as it goes deeper.
At the end of the bottom piece 2d of the valley water receiving member 2, a water return edge 4 is provided if necessary. The valley water receiving member 2 is arranged on the roof base waterproof sheet 5 along the valley portion, and the bottom piece 2d is placed on the roof base waterproof sheet 5. And the end of the roof tile 3 that is roofed is the folded piece 2b and the bottom piece of the valley water receiving member 2.
It is fitted between 2d. The valley portion of the roof is constructed in this way, and the rainwater flowing from the roof tile 3 is received by the valley water receiving member 2, but the rainwater flows in the longitudinal direction along the upper surface piece 2a, and the folded piece 2b and the roof tile 3 are received. Flowing along
It flows along the hanging piece 2c and the bottom piece 2d. Further, since the folded piece 2b and the bottom piece 2d of the valley water receiving member 2 can be vertically deformed, the end portion of the roof tile 3 can be fitted even if the slope of the roof changes.

Further, FIG. 3 shows another embodiment in which a valley waterproof sheet material 6 is laid under the valley water receiving member 2. The valley prevention sheet material 6 is wider than the valley water receiving member 2, and fin-shaped water return portions 7 are provided on the upper surfaces of both sides in the longitudinal direction. It is supposed to improve.

[Effects of the Invention] As described above, the present invention has an upper surface piece having a substantially V-shaped cross section, a folding piece folded from both ends of the upper surface piece, a hanging piece hanging downward from an end of the folding piece, and a lower end of the hanging piece. A valley water receiving member made of a metal plate is formed with the bottom piece that extends outward so as to be substantially parallel to the upper surface piece, and the valley water receiving member is arranged along the valley part of the roof so that the bottom piece is the valley of the roof. Place it on the base of the department,
Since the end of the roof tile that is roofed is fitted between the folded piece and the bottom piece of the valley water receiving member, the end of the roof tile is covered with the folded piece, the hanging piece, and the bottom piece, and the roof tile has an opening. It is possible to construct it with an appearance that can not be seen, and it can be constructed by fitting the end of the roof tile even if the folding piece or bottom piece may be deformed and the roof slope changes. Since the inclination of the folded piece of the receiving member is made steeper than the inclination of the top piece and the bottom piece, the gap between the folded piece and the bottom piece gradually becomes wider toward the outside, and the gap between the folded piece and the bottom piece becomes wider. When the end of the roof tile is inserted into the gap, the opening of this gap is wide and it is easy to insert the roof tile, and the workability is good, and the roof tile is inserted in the gap between the folded piece and the bottom piece. When the end is inserted all the way in, the roof tiles are elastically pressed by the folding piece and the In which it is mounted so as tiles do not rattle.
