Description

[Detailed description of the invention] [Industrial application field] This invention relates to a metal plate for roofing.

[Conventional technology and its problems]

Metal sheets for roofing include galvanized iron sheets, copper sheets,
One long side edge of the oblong rectangular main plate made of a corrosion-resistant metal plate such as an aluminum plate has a gap that is folded back toward the front side, and the other long side edge has a gap that is folded back toward the back side. The flaps are engaged with oppositely folded flaps formed on opposite edges of adjacent metal.

By the way, in order to construct a roof using this metal plate, it is necessary to lay it from the eave side to the ridge side and fix each metal plate with a hanger. When stacking the metal plates, even if the flaps are fitted onto the fixed metal plates, they will slide down when released, making the work of fixing them with hangers complicated.

In addition, when the roof is covered with this metal plate, rainwater does not infiltrate into the roofing board from the joint in the slope direction, but when there are strong winds or long rains, water leaks into the joint from the gap in the joint. Rainwater infiltrates due to capillary action, and the infiltrated rainwater does not flow out easily, causing various problems.

This idea is an attempt to solve the above problems, and its purpose is to make it easy to roof with metal sheets, and to make it easy for rainwater to flow into the seams when the roof is covered. To provide a metal sheet for roofing that can be discharged.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention has a protrusion that extends over the entire length of the edge toward the tip edge of the edge that is folded back on the back side of the other long edge (the edge corresponding to the lower sloped side of the roof). The protrusions are formed by punching in alternating directions, and are formed by punching at least on the inside of the seam. This is a roofing metal plate with a stopper.

〔Example〕

FIG. 1 is a right side view of the center vertical section of the metal plate for roofing according to the present invention, and the plan view is omitted, but this metal plate 1 is shown in the second side view in the usage mode.
As can be understood from the figure and the enlarged side view of the essential parts in Fig. 3, there is a seam 2a folded back to the front side on one long edge of the roof, which is the upper sloped side of the roof, and a seam 2a on the other long side, which is the lower sloped side of the roof. The edge is provided with a gap 2b that is folded back to the back side, one short edge (left edge) has a gap 3a that is folded back to the back side, and the other short edge (right edge) has a main part of the metal plate 1. As shown in FIG. 4, a seam 3b is provided which is folded back to the front side. However, the edges on both short sides may be folded back toward the same surface.

As shown in FIG. 4, the flap 2b on the other long side is provided with protrusions 4a and 4b which are embossed in alternating directions from front to back over the entire length of the flap near the leading edge of the flap, as shown in FIG. 5 is the cut line in the direction of the edge of the seam.
The veranda is more prominent.

This metal plate is laid on the sheathing board 6 of the roof, from the eave side to the ridge side, and from the left side to the right side, fitting the gaps on the opposite edges, and each metal plate has a gap 2a. Most of the front end of the hanger with the fitted edges is stacked and nailed onto the roofing board 6, but the hanger is omitted from illustration.

When roofing is done as described above, the gaps 2a and 2b between the metal plates 1 and 1a that are adjacent in the inclination direction are
In the fitted state, as shown in Fig. 3, the externally fitting gap 2b has a protrusion 4a protruding toward the middle and outer side (lower side in the figure) provided near the tip edge of the protrusion 4a that is attached to the adjacent metal plate. Upon contact, an appropriate gap is formed between the gap 2b and the gap 2b, so that even if rainwater flows into the gap during rain, it easily flows out.

Further, the protrusion 4b engages with the tip edge of the gap 2a of the adjacent metal plate, and since at least the protrusion 4b is formed by punching out the outside from the notch 5, it is formed by this notch. The straight edge of the protrusion reliably engages with the tip edge of the facing and mating gap 2a, so that even if the metal plate 1a is not yet fixed with a hanger, the metal plate 1a on the upper inclined side will not slip. It never goes down.

In the figure, 7 indicates a heat insulating layer on the back side of the metal plate, 8 indicates a decorative roof board, and 9 indicates an eaves gutter.

〔effect〕

The metal plate for roofing of this invention has the following effects.

(1) On the other long edge of the metal plate (lower sloped side of the roof) that is folded back to the back side, protrusions are formed on the edge toward the tip edge in alternating directions, covering the entire length of the edge. Therefore, when flat roofing is done with this metal plate, when both edges of opposing edges of adjacent metal plates are fitted in the inclined direction, the protrusion facing outward of the outer fitting edge will come into contact with the top surface of the adjacent metal plate. An appropriate gap is created between the externally fitting gap and the externally fitting gap, so even if rainwater flows into the gap during rain, it can easily flow out, making it possible to avoid the external fitting gap found in conventional metal plates. This eliminates the inconvenience that there is no gap between the upper surfaces of the mating metal plates, and rainwater enters by capillary action and cannot easily flow out.

(2) When the seam having the protrusion is externally fitted into the opposing seam of adjacent metal plates on the lower sloped side of the roof, the projection protruding on the inner side of the seam is locked to the tip edge of the mating seam. At the same time, since this protrusion is formed by punching out the outside of the notched line in the direction of the edge of the edge of the flap, the straight edges of the protrusion formed by this notched line will face and fit together. This ensures that the metal plate on the upper side of the slope of the roof does not slide down even if you let go of it before it is fixed by the hanger, making it easier to do the roofing work. becomes easier.
