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 roofing material main body 1 made of a metal plate.
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 end side of the folded piece 3 to extend outward from the side edge of the roof material body 1. A drain cutter piece 4 is provided, and the recess formed by the extended base portion of the drain cutter 4 and the folded piece 3 is used as an insertion recess 5 into which the insertion piece 2 is inserted, and the edge of the roofing material body 10 side is is folded back to the upper side to form the upper thread stopper 9, and the eave side edge of the roofing material main body 10 is folded back to the lower side to form the bobbin thread stopper 10, and the eave side edge of the waste drainer piece 4 is folded downward. The front piece 7 is bent to form a front piece 7 located slightly behind the front face of the bobbin thread stopper 10, and the front piece 7 is discarded to form a triangular shape in which the drooping length becomes shorter toward the tip of the drainer piece 4.
Relating to a roof material characterized in that a protrusion 8 extending from the eave side to the ridge side is protruded near the insertion recess 5 on the upper surface, and the tip of the waste water cutter 4 is folded back to the surface side to form a water cutter 6. It is something.

Conventionally, a draining piece 4 provided on the roofing material body 1
The end of the eave side is as shown in Figure 1, and there is a problem that drainage at the end of the eave side is poor, and rainwater accumulates on the drainage strip 4, which has an adverse effect on the metal roofing material. Furthermore, there was a problem in that rainwater ran down the lower surface of the drainage strip and entered the roof base material.

Furthermore, when stepping on the roof after construction, the draining piece is crushed and the draining effect is lost, and the insertion piece and the draining piece are in close contact with each other, causing rainwater to rise upward due to capillary action.

The present invention was invented in view of the above-mentioned points, and an object of the present invention is to hang the front piece downward from the eave side end of the waste water cutter, so that the eave side of the waste water cutter is Improve drainage at the ends to prevent rainwater from accumulating in the draining strips, and prevent rainwater from flowing to the back side of the draining strips.Additionally, drain the draining strips at the top from the eaves side to the ridge side. Providing the ridges prevents the draining strips from collapsing, and the rainwater on the draining strips is guided by the ridges to flow, making drainage even smoother. is to provide a roofing material that can prevent rainwater from running off.

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 roof material main body 1 through a side step 12, and both sides of the insert piece 2 are cut out so that the extending tip is slightly midway compared to the extending base. By making the extending tip slightly sandwiched in this manner, insertion into the insertion recess 5 can be easily performed.

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.

Front piece 7 facing downward from the edge of the eave side
The front piece 7 has a triangular shape with a hanging length becoming shorter toward the tip of the draining piece 4.

A plurality of (two in the illustrated embodiment) protrusions 8 are protruded from the upper surface of the draining piece 4 from the eaves side end to the ridge side end.

The protrusions 8 are formed by, for example, a press.

Of course, the protrusions 8 may be formed by other means.

Further, the tip of the waste draining piece 4 is folded back toward the front side to form a draining piece 6.

The edge on the ridge side of the roofing material body 1 is folded back to the upper surface side to serve as a needle thread stopper 9, and the edge on the eave side of the roofing material body 1 is folded back to the lower surface side to serve as a bobbin thread stopper 10. .

Further, the end of the upper thread stopper piece 9 on the side of the waste water cutter piece 4 is further folded back to the upper surface side, and then extends along the upper side of the waste water cutter piece 4 as an extended upper locking piece 11.

Here, the front piece T is set to be located slightly rearward than the bobbin thread stopper piece 10.

In this case, for example, the front piece 7 is located about two baskets behind the bobbin thread stopper piece 10.

In the case of a roofing material having the above structure, the insertion piece 2 of an adjacent roofing material is inserted into the insertion recess 5 to connect the roofing materials laterally, and the bobbin string stopper 10 of the upper roofing material is connected to the lower thread stopper 10 of the upper roofing material. It is engaged with the upper thread stopper piece 9 of the roofing material to connect the roofing materials in the vertical direction.

When rainwater enters onto the draining strip 4 from the horizontal connection, it flows over the draining strip 4 toward the eave side end, is guided by the front strip 7, and flows downward to the upper surface of the lower roofing material. It flows to

In this case, rainwater hardly flows to the side of the draining strip 6 due to the presence of the ridge 8 on the upper surface of the draining strip 4 that protrudes from the eaves side to the ridge side. Almost no rainwater flows into the short hanging length part of the piece 7, and rainwater is prevented from flowing from between the lower surface of the drainage cutter piece 4 and the upper surface of the upper thread stopper piece 9 to the roof base material side.

In addition, the presence of the protrusion 8 prevents the end of the roofing material body 1 on which the insertion piece 2 is provided from being crushed even if the roof surface is stepped on with a foot, and the end of the roofing material body 1 on which the insertion piece 2 is provided is prevented from being crushed. part and the waste water cutter piece 4 of the adjacent roofing material main body 1 are not in close contact with each other,
A space is maintained between the two to prevent rainwater from moving upwards due to capillary action.

Of course, the protrusion 8 has the role of preventing the drainer piece 6 from being crushed, but especially if the protrusion 8 is provided at the lower position of the drainer piece 6 of the waste drainer piece 4 as in the embodiment shown in the figure. This can further prevent the draining piece 6 from collapsing, and even if rainwater should cross over the protrusion 8, the water can be reliably drained by the draining piece 6.

By positioning the front piece 7 and the lower thread stopper 10 slightly behind the front piece 7 and the bobbin thread stopper 10 of the adjacent roofing material.
This creates a space between the two and allows for better drainage.

Furthermore, in the structure of the present invention in which the upper thread stopper piece 9 and the bobbin thread stopper piece 10 are locked, the front piece 7 is discarded and the draining piece 4 is formed into a triangular shape with a shorter hanging length toward the distal end. Therefore, during construction, the front piece 7 does not get caught on the bobbin thread stopper 10, and the construction can be easily performed.

Thus, in the present invention, as described above, the eave side end of the draining piece is bent downward to form the front piece.
At the eave-side end of the drainage cutter, the front piece acts as a guide to allow rainwater to flow smoothly downward.In addition, by providing the front piece, rainwater flows down the bottom side of the drainage cutter and flows toward the roof base material. It has the advantage that it prevents water from flowing into the roof, does not corrode the roof base material, and also prevents rain.

Furthermore, since the front piece is discarded and the drooping length becomes shorter toward the tip of the draining piece, it is triangular in shape. It is possible to smoothly cover the lower thread stopper of the roofing material which is inserted into the front piece without being obstructed by the pieces.

In addition, since the upper surface of the drain strip is provided with a protrusion that extends from the eave side to the ridge side, even if you step on the root surface after installation, the end of the roofing material body will not be crushed and come in close contact with the drain strip. ,
It can prevent rainwater from flowing upwards due to capillary action, and the ridges also prevent the draining strips from collapsing and do not reduce the draining effect.Furthermore, the ridges allow rainwater that has entered the draining strips to flow toward the eaves. Since it is guided, water can be drained smoothly, and water is drained more reliably by using two types of draining means, ridges and draining pieces.

Furthermore, due to the presence of the protrusion near the insertion recess, rainwater on the draining frame hardly flows into the short hanging length of the front piece, and there is no risk of rainwater being transmitted to the bottom side of the draining piece. .
