Field of the Invention The present invention relates to an engaging portion having a face plate portion in which peaks and valleys are alternately formed, and the eaves side of the face plate portion is folded down and then bent toward the ridge (back side). The present invention relates to a metal-molded tile that has a locking portion that is bent to the eaves side (front surface side) after the ridge side of the face plate portion is raised, and the locking portion is fixed by a hook.

[0002]

2. Description of the Related Art As one example of the prior art, there is a flat tile portion of a molded tile roof material disclosed in Utility Model Publication No. 27935/1992. The flat tile portion of the roof tile material shown here will be described as a “metal roof tile” in a unified manner with the present invention. This metal-molded tile has a flat top and a valley, which are alternately formed.The eaves side is folded down and then bent to the ridge side to form an engaging part. It is bent to the side to form a locking portion. Then, the metal mold tile is fixed to the base material using a fastener, and a metal mold tile to be constructed on the upper tier is combined therewith to be constructed.

[0003]

SUMMARY OF THE INVENTION In the metal molded roof tile shown in the present invention, the shape of the top of the mountain is flat, and a metal fitting is fixed thereon, and the metal roof is covered with a round roof. The main focus is. For this reason, no attempt has been made to form a mountain portion that draws a beautiful curved surface, and instead, a round tile portion is applied to make the appearance of the mountain portion curved.

[0004]

According to the present invention, there is provided a metal roof tile comprising:
As an outline, it is formed by press-molding a metal plate with a mold, and is fixed using a hook. In particular,
A face plate portion in which curved ridges and valleys are formed alternately, an engaging portion in which the eaves side of the face plate portion is folded down and then bent to the ridge side (back side), and a ridge side of the face plate portion stand. It has a locking portion that is raised and then bent toward the eaves side (front side). In the engaging portion, the bent portion toward the ridge side is the lower surface of the engaging portion composed of a lower surface peak portion and a lower surface valley portion, and the bent portion toward the eave side in the locking portion is the upper surface peak portion and the upper surface valley portion. And the upper surface of the locking portion. It is preferable to form a recessed portion in the upper valley portion in consideration of the thickness of the suspender. Then, it is preferable to design the shape of the metal molded roof tile by setting the interval in the left-right direction of the concave portion so as to match the pitch of the base material, tarki. Further, ribs may be provided on both sides of the mountain (the boundary between the mountain and the valley) to give a design accent and to make the mountain and the valley clear. Furthermore, when the metal molded roof tile is viewed from the surface side, the right side and the eaves side are retracted toward the ridge side at the engagement portion, and formed.
On the other hand, in the locking portion, the left side and the ridge side may be retracted toward the eave side. The formation of the engaging portion and the locking portion may be reversed left and right.

The most characteristic feature of the metal roof tile of the present invention is that it has the following configuration. In this metal molded roof tile, when the width of at least the eaves-ridge direction of the lower surface valley portion of the portion to be combined with the suspender on the lower surface of the engaging portion is a predetermined width, the width of the other lower surface of the engaging portion is It is formed narrower than a predetermined width. That is, in the lower surface valley portion, the width of the other lower surface of the engaging portion is narrower at least based on the width of the portion (width in the eaves-ridge direction) that covers the suspension.

[0006] Such a metal molded roof tile is constructed using a suspension, which has, for example, a fixed surface.
An upright portion in which one side of the fixed surface is raised substantially at a right angle, a flat portion in which an upper edge of the raised surface portion is bent at a substantially right angle in a direction opposite to the fixed surface, and a folded portion in which the flat portion is folded down. It is good to have what has. Then, such a suspender is placed on the upper surface of the locking portion of the metal molded roof tile, and the fixing surface is fixed to the base material with a fastener such as a nail. The construction of the metal-molded tile in the left-right direction is performed by overlapping the metal-molded tile to be constructed next to the metal-molded tile that has already been constructed. At this time, it is preferable to form a groove in a mountain portion below the overlapping portion to prevent the capillary phenomenon. In the eaves-to-building direction, the metal-roofed tiles are installed by connecting the engaging portions of the metal-roofed tiles installed on the upper level (ridge side) to the locking portions of the metal-typed tiles installed on the lower level (eave side). Is carried out in such a manner that it is combined with the fixed suspension.

[0007]

The metal-molded tile of the present invention is manufactured by press-molding a metal plate. At this time, when the metal plate to be pressed is cut, at least the lower step is formed on the lower surface of the engaging portion. When the width of the lower surface valley portion of the portion to be combined with the hanging member fixing the metal molded roof tile is set to a predetermined width, the width of the other lower surface of the engaging portion is made smaller than the predetermined width. is there. The following phenomena, which are the characteristics of press-forming a metal plate, are achieved by making the bottom ridge narrower without making the width of the bottom ridge and width of the bottom valley the same. To prevent it. That is, the folded portion of the engaging portion and the rising portion of the locking portion are formed, and then the lower surface of the engaging portion and the upper surface of the locking portion are formed. At the point where the metal plate is most likely to shrink when folded down, the fabric becomes wrinkled, and when it is bent to form the lower surface of the engaging portion, the metal plate spreads and becomes wavy Conversely, at the boundary between the peak and the valley where the metal plate is about to extend, a crack is generated in the process.

An embodiment of a metal roof tile A according to the present invention will be described with reference to FIGS. This metal molded roof tile A
It is formed by pressing a metal plate with a mold. In the case of the present embodiment, the metal plate is cut, and then the peaks 4 and the valleys 5 are formed, or the metal plate is engaged with the locking portion 1. The process of forming the part 2 is performed. Then, the face plate portion 3 in which the curved peak portions 4 and the valley portions 5 are alternately formed, and the eaves side of the face plate portion 3 is folded down and then bent toward the ridge side (back side), and has a substantially U-shaped cross section. It has an engaging portion 2 and a locking portion 1 having a substantially U-shaped cross section, which is formed by erecting the ridge side of the face plate portion 3 and then bending it toward the eaves side (front surface side). In the metal-molded roof tile A of this embodiment, the height difference between the crests 4 and the valleys 5 is about 20 mm. However, since the valleys 5 are almost flat, the curved crests 4 are emphasized. I have.

In the engaging portion 2, the bent portion toward the ridge side is an engaging portion lower surface 21 composed of a lower surface mountain portion 21a and a lower surface valley portion 21b. , Top mountain portion 11a and top valley portion 11b
And an upper surface 11 of the locking portion. In the upper valley portion 11b, a concave portion 12 on which a hanging member B described later is placed is formed. The concave portion 12 is depressed in consideration of the thickness of the hanging member B. For example, when stepping from above during construction, traces of the hanging member B appear on the surface side of the metal-molded tile A and impair the appearance. Is preventing. In addition, the metal molded roof tile A of the present embodiment
Is designed such that the interval between the concave portions 12 in the left-right direction is set to match the pitch of tarki which is a part of the base material. By doing so, positioning is performed at the time of the first construction, so that the subsequent suspension B can be easily fixed. In the case of the present embodiment, stopping the hangers B at every third position is suitable for 455 mm pitch tarki. As in the present embodiment, a design accent is applied to both sides of the mountain portion 4 (a boundary between the mountain portion 4 and the valley portion 5) to give a design accent.
Ribs 31 may be inserted to make the valley 5 clear.

The metal-molded roof tile A of the present embodiment is constructed in combination in the left-right direction and the eaves-ridge direction.
It has the following configuration. First, the left side (the left side in FIG. 2) of the metal molded roof tile A to be constructed next to the right side (the right side in FIG. 2) of the already formed metal roof tile A is combined. At this time, the engaging portion 2 on the right side and the eaves side with respect to the metal roof tile A is formed by being retracted toward the ridge side as shown in FIG. On the other hand, the locking portion 1 on the left side and on the ridge side is formed to be retracted toward the eaves side as shown in FIG. For this reason, when the engaging portions 2.2 of the metal molded roof tiles A, A adjacent to the right and left and the locking portions 1.1 are combined, the eaves side are not substantially irregular, but are aligned substantially in a straight line. It can maintain a sense of unity without impairing the rain, and it is difficult for rainwater to enter through gaps. Further, a groove portion 41 is formed at the top of the mountain portion 4 at the right end (that is, on the lower side of the overlapping portion), and the groove portion 41 is blown up from the gap between the combined portions of the face plate portions 3. Even if rainwater enters the sea, it is prevented from penetrating into the interior by capillary action.

Further, the metal molded roof tile A of the present invention is characterized by the following measures. The metal molded roof tile A is formed such that the width of the lower surface mountain portion 21a is smaller than the predetermined width on the lower surface 21 of the engaging portion. That is, when the width of the lower surface valley portion 21b is used as a reference in the lower surface 21 of the engaging portion, the width of the lower surface mountain portion 21a is narrower. When the width of the lower surface valley portion 21b of the engaging portion lower surface 21 at least where the lower surface valley portion 21b is combined with the hanging member B fixing the metal molded roof tile A installed in the lower step is set to a predetermined width, Lower surface 21 of the engaging portion other than
Is formed narrower than a predetermined width. That is, in the lower valley portion 21b, at least the width (width in the eaves-ridge direction) of the portion on which the hangers B are covered is defined as:
The width of the other lower surface 21 of the engaging portion is smaller. In other words, the wide portion may be at least a portion to be combined with the hook B.

The metal-molded roof tile A of the present invention is manufactured by press-molding a metal plate.
The width of the lower valley portion 21a is made narrower without making the width of a and the width of the lower valley portion 21b the same.
The reference, wide part is at least the bottom trough 2
In FIG. 1b, it is a portion to be combined with the hangers B, and the width thereof is the width in the eave-ridge direction of the portion where the hangers B are covered. If the width is the same, as described above, when pressed, the area near the top of the crest 4 is folded down, and where the metal plate is most likely to shrink, wrinkles tend to approach the fabric. State, and the engagement portion lower surface 21
When the metal plate is bent to form a groove, the metal plate spreads and becomes wavy, and conversely, at the boundary between the peak 4 and the valley 5, where the metal plate is about to extend, a crack is formed in the process. The phenomenon that occurs occurs, and it does not become the mountain part 4 that draws a beautiful radius, but it does not work as a product without drawing a beautiful curved surface with a predetermined dimension. In particular, since the folded portion of the engaging portion 2 on the eaves side is not a hidden portion, a defective shape should not be exposed over the entire roof surface.

As described above, even if the width of the lower surface peak portion 21a on the lower surface 21 of the engaging portion is smaller than the predetermined width, the width of the lower surface valley portion 21b on the lower surface 21 of the engaging portion is at least combined with the hook B. The part to be formed has a predetermined width. For this reason, the hanging part B is put on the concave part 12 of the locking part upper surface 11, and the engaging part 2 of the metal molding
Is combined, the width of the lower surface valley portion 21b of the engagement portion lower surface 21 is a sufficient width, and strength can be maintained. In addition, the goby assembling portion between the lower valley portion 21b and the upper valley portion 11b may be infiltrated by rainwater, but at least if the portion of the hangers B of the lower valley portion 21b is wide, it is deeply engaged. Even if rainwater infiltrates from the lower side of the lower surface valley portion 21b by going back to the face plate portion 3, it is difficult for the water to penetrate into the inside. Since the width of the lower valley portion 21b is a predetermined width and can be firmly combined with the suspender B fixing the metal molded roof tile A installed in the lower step,
In extreme terms, the width of the lower surface mountain portion 21a may be such that the end surface is folded so that the cutout of the end surface is not visible.

A state in which such a metal-molded roof tile A is constructed using the hangers B will be described with reference to FIG.
An example will be described. The suspension B shown in FIG.
A fixed surface B1, an upright surface portion B2 having one side of the fixed surface B1 raised substantially at a right angle, a flat surface portion B3 obtained by bending an upper edge of the upright surface portion B2 at a substantially right angle in a direction opposite to the fixed surface B1; And a folded part B4 obtained by folding the flat part B3. In the case of the present embodiment, the folded-down portion B4 is folded stepwise to increase the strength, and the lower edge thereof is folded inward at a substantially right angle. It is preferable to make a hole in the fixing surface B1 in advance.

The hanging member B having such a structure is connected to a metal roof tile A.
Over the concave portion 12 of the upper surface 11 of the fixing portion, and fix the fixing surface B1.
Is fixed to a base material (not shown) with a fastener. And
The engaging portion 2 of the metal-molded roof tile A to be constructed on the upper stage is put on the folded-down portion B4 of the suspension B to which the metal-molded roof tile A is fixed. Combine to stop 1. In other words, the upper valley portion 11b
The bottom valley portion 21b and the bottom ridge portion 21a are respectively formed into the upper ridge portion 11a. The left and right metal molded roof tiles A and A are installed on the ridge 4 (the right side in FIG. 2) on the side where the groove portion 41 is present in the metal molded roof tiles A already installed. Crest portion 4 (crest portion 4 without groove portion 41, FIG. 2
The metal molded roof tile A is then moved from the eaves side to the ridge side, and the locking portions 1 and 1 and the engaging portion 2 are overlapped.
-Combine the two.

If the metal-molded roof tile A and the hangers B according to the present embodiment are used, the construction can be performed without the influence of the thickness of the hangers B on the surface of the metal-molded roof tile A due to the presence of the concave portion 12. Can be. Further, since the groove portion 41 is formed, even if rainwater enters so as to blow up from a gap between the combined portions of the face plate portions 3 of the metal molded roof tiles A, the water penetrates into the inside due to the capillary phenomenon. Is preventing. Further, as illustrated in detail in FIGS. 10 and 11, the engaging portion 2 on the right side and the eave side toward the metal molded roof tile A in FIG. 2 is formed by being retracted toward the ridge side. The locking portion 1 on the left side and on the ridge side is formed to be retracted toward the eaves side. For this reason, when the engaging portions 2.2 of the metal molded roof tiles A adjacent to the left and right and the locking portions 1.1 are combined, the eaves side are not aligned, and are aligned substantially in a straight line. It can maintain a sense of unity without impairing the rain, and it is difficult for rainwater to enter through gaps. In addition, the shape of the engaging portion 2 and the engaging portion 1 is substantially U-shaped in cross-section, so that they have strength. When is lifted by the wind, the lower edge of the folded-down portion 4B can press the inside (back surface side) of the lower surface 21 of the engaging portion from above, so that the strength can be further maintained.

[0018]

The peak of the conventional metal-molded tile has a flat top, and no attempt has been made to form a peak that draws a beautiful curved surface. Instead, the tile is covered with a round tile. Although it had to be, according to the metal molded roof tile of the present invention,
Since the width of the ridge is formed narrower than the predetermined width on the lower surface of the engaging portion, a clean curved ridge can be formed.
