Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roofing material, in which an insertion piece 2 is extended outwardly from one side of a metal roofing material main body 1, and the roofing material main body 1 is made of metal.
The other end is folded back along the lower surface side to form a folded piece 3, and the tip of the folded piece 3 is folded back along the lower surface side of the folded piece 3 to extend outward from the side edge of the roof material body 1. A waste draining piece 4 is provided, a recess formed by the extended base portion of the waste draining piece 4 and the folded piece 3 is used as an insert portion 5 into which the insert piece 2 is inserted, and the eave side end edge of the roofing material body 10 is The lower stop piece 11 is formed by the hanging piece 13 bent downward and the horizontal piece 16 by folding the lower end of the hanging piece 13 back toward the ridge side edge. An upper locking piece 10 that can be folded back to lock the lower stopper piece 11 is formed, and the upper locking piece 10 is folded downward over approximately the entire area of the eave side end edge of the drainage cutter piece 4, including the back of the hanging piece 13. Bend it to form a front piece 6, provide a drainage hole 7 at the rear of the front piece 6 of the waste water cutter 4, provide a rear hanging piece 8 downward at the rear edge of the drain hole 7, and This relates to a roofing material which is provided with a draining part 9 which is folded back to the upper surface side of a draining piece 4 at the extending tip.

Conventionally, the eave side end of the drain strip 4' provided on the roofing material body 1' is as shown in Figure 1, and when the roofing material is connected vertically, it becomes the drain strip 4'. Rainwater easily enters between the flap-shaped upper locking piece 10' and the hanging piece 1 of the lower stopper piece 11' if the roofing material is still connected laterally.
3' and the hanging piece 13' of the adjacent lower stop piece 11'.
There is a problem that rainwater blows in through the gap A shown in the figure.

The present invention was invented in view of the above points, and its purpose is to prevent rainwater from blowing in from the lateral connection portion, and furthermore, to prevent rainwater from entering between the drainage cutter and the upper locking side. We provide roofing materials.

The present invention will be explained in detail below with reference to Examples.

In the figure, reference numeral 1 denotes the roof material body, which is made of a copper plate, a galvanized iron plate, or a resin-coated metal plate.

An example of the roof material main body 1 is as follows.

For example, after sulfurizing the surface of a copper plate or copper-plated plate, a scratch pattern is applied to give it an oxidized copper-like appearance, and then this is coated with a transparent synthetic resin such as alkyd, melamine, or polyester. The roof material main body 1 is formed by bending.

An insert piece 2 extends from one side of the roofing material body 1 through a side step 14, and both sides of the insert piece 20 are cut out so that the extending tip is slightly shaped like a mountain monkey compared to the extending base. By making the extending tip slightly curved in this manner, it can be easily inserted into the insertion recess 5.

The other side of the roof material body 1 is folded back along the lower surface side to form a folded piece 3, and the tip of the folded piece 3 is folded back along the lower surface side of the folded piece 3 to form a folded piece 3 that is lower than the side edge of the roofing material body 1. A draining piece 4 is provided extending outward, and a recess formed by the extending base portion of the draining piece 4 and the folded piece 3 is used as an insertion recess 5 into which the insertion piece 2 is inserted. It is.

Front piece 6 facing downward from the edge of the eave side
is drooping.

Further, the tip of the waste draining piece 4 is folded back toward the front side to form a draining portion 9.

Further, a horizontally elongated drainage hole 7 is provided at the rear of the front piece 6 of the waste draining piece 4, and a rear hanging piece 8 is provided at the rear edge of the drainage hole 7.

The edge of the roofing material body 10 on the ridge side is folded back to the upper surface side to serve as the upper locking piece 10, and the edge of the eave side of the roofing material body 1 is folded back to the lower surface side and the lower end of the hanging piece 13 and the hanging piece 13. The lower locking piece 11 is made up of a horizontal piece 16 which is folded back toward the ridge side end edge.

Further, the end of the upper locking piece 10 on the side of the waste water cutter 4 is further folded back to the upper surface side and then extends along the upper edge of the waste water cutter 4 to form an extended upper locking piece 12.

Here, the horizontal piece 16 of the upper locking piece 10 is shorter than the lower locking piece 11, and when the lower locking piece 11 is locked to the upper locking piece 10, the tip of the upper locking piece 10 and the rear hanging piece 8 A gap 15 is formed between the draining piece 4 and the upper locking piece 10 to prevent rainwater from entering between the drainage piece 4 and the upper locking piece 10 due to capillary action.

However, with the roofing material having the above structure, the insertion piece 2 of the adjacent roofing material is inserted into the insertion recess 5 to connect the roofing materials laterally, and the lower locking piece 11 of the upper roofing material is inserted into the insertion recess 5. It is engaged with the upper locking piece 10 of the roofing materials to connect the roofing materials in the vertical direction.

When rainwater enters onto the drain strip 4 from the horizontal connection, it flows over the drain strip 4 toward the eave side end, and flows from the drainage hole to the upper surface of the lower roofing material using the rear hanging strip 8 as a guide. It is something that flows.

Here, rainwater can be drained from the drainage hole 7 in the draining piece 4, so the hanging piece 13 of the lower locking piece 11 of the front piece 6 and the adjacent roofing material can be drained.
When viewed from the front, there is no gap at the lateral connection part, which prevents rainwater from blowing in from the front.

In the present invention, as described above, a hanging piece is formed by bending the eave side edge of the roofing material body downward, and a horizontal piece is made by folding the lower end of the hanging piece back toward the ridge side edge. Form a piece, and bend the eave side end edge of the waste water cutter downward over almost the entire area of the eave side edge of the waste water cutter including the back of the hanging piece to form a front piece. A drainage hole is provided at the rear of the drain hole, a rear hanging piece is provided at the trailing edge of the drainage hole, and a draining part is provided at the extending tip of the waste draining piece, so that it is difficult to see from the front at the lateral connection part. Even if rainwater tries to blow in, the front piece can prevent this rainwater from blowing in, and since it has a drainage hole, the rainwater on the draining piece will be drained from the drainage hole, and as a result, the front piece and the adjacent roofing material will be drained. There is no need to provide a gap for drainage between the hanging piece of the lower locking piece, and the front piece and the hanging piece of the lower locking piece of the adjacent roofing material can be brought into close contact with each other. The front piece can prevent rainwater from blowing in from the drain hole, and the rainwater flowing from the drainage hole is guided by the rear hanging piece, and the rainwater does not flow between the drainage cutter and the upper locking piece. It has the advantage that it does not infiltrate.
