Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roofing material, in which an insertion piece 2 extends outward from one side of a roofing material main body 1 made of a metal plate, and the other side of the roofing material main body 1 is extended outward. is folded back 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 roofing material main body 1 to provide a draining piece 4. The recess formed by the extended base portion of the waste water cutter piece 4 and the folded back piece 3 is used as the insertion recess 5 into which the insertion piece 2 is inserted, and the extended tip of the waste water cutter piece 4 is folded back to the surface side to release the water. This roofing material is characterized in that it has a single-cut protrusion 6 and a plurality of small protrusions 7 are spaced apart from each other in the longitudinal direction on the lower surface side of the water-folded protrusion 6.

With conventional metal roofing materials, a draining protrusion 6 was simply provided at the tip of the draining strip 4, so when it rides on the root surface after construction and is subjected to pressing force in the direction of arrow A in Figure 1, There was a problem in that the draining protrusion 6 was crushed and the draining effect was lost.

For this reason, it is conceivable to provide a deformation prevention fold 12 over the entire length of the draining protrusion 6 in the longitudinal direction as shown in FIG. There was a problem in that the deformation-preventing fold 12 became a draining part, and the part indicated by A in FIG. 2 did not function as a drainer, and the draining effect could not be sufficiently exerted.

The present invention was invented in view of the above points, and its purpose is to provide a plurality of small protrusions in the longitudinal direction on the lower surface of the draining protrusion, so that it does not rest on the root surface after construction. Even if the draining protrusion is used, the draining protrusion does not get crushed, and a gap is formed that communicates with the part between the small protrusions and the part between the protruding base of the draining protrusion and the small protrusion, so that the colander can be drained even in this part. Our goal is to provide roofing materials that work well and maximize drainage effects.

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

In the figure, reference numeral 11 indicates the roofing material body, which is made of a copper plate, a galvanized iron plate, a resin-coated metal plate, or the like.

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

For example, the surface of a copper plate or copper plated plate is sulfur-colored, then VC and scratch patterns are 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 the roof material.

An insert piece 2 extends from one side of the roofing material main body 1 via a stepped portion 8, and both sides of this insert piece 2 are cut out so that the extending tip is slightly sandwiched in the middle. By doing so, it can be easily inserted into the insertion recess 5.

The other end 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 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.

In addition, the extension and tip of the waste drainer piece 4 is folded back to the surface side to form a drainer protrusion 6, and a plurality of small protrusions 7 are provided at regular intervals in the longitudinal direction of the lower surface of the drainer protrusion 6. It is.

Here, the small protrusions 7 are formed by pressing, but they may be formed by other methods.

In the present invention, in which the small protrusions 7 are spaced apart in the longitudinal direction on the lower surface of the draining protrusion 6, gaps are formed between the small protrusions 1, and gaps are formed between the small protrusions 7 and the protruding base of the draining protrusion 6. is formed, both gaps communicate with each other, and the lower surface side of the draining protrusion 6 functions as a drainer.

The ridge side edge of the roofing material body 10 is folded back to the upper surface side to serve as an upper locking piece 9, and the eave side edge of the roofing material body 1 is folded back to the lower surface side to serve as a lower locking piece 10.

Further, the end of the upper locking piece 9 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 catch piece 11. In the case of a 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 10 of the upper roofing material is inserted into the insertion recess 5 of the lower roofing material. It is engaged with the upper locking piece 9 of the roofing materials to connect the roofing materials in the vertical direction.

Thus, in the present invention, as described above, a plurality of small protrusions are provided at intervals in the longitudinal direction on the lower surface of the draining piece, so even if it rides on the roof surface after construction, the small protrusions are removed and the upper surface of the draining piece This prevents the draining protrusions from being crushed, and there are gaps between the small protrusions and gaps between the small protrusions and the protruding base of the draining protrusions. Since water can be drained in this gap, it is advantageous to provide a small protrusion to prevent the draining protrusion from collapsing.
