DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. First, a rainwater drainage structure when the rainwater leakage prevention member according to the present invention is not used will be described with reference to FIG. Fig. 10 is a perspective view showing a rainwater drainage structure in a corrugated slate roof when no leak prevention member is used. As shown in Fig. 10, a rain gutter 20 is provided between two corrugated slate roofing materials 10, and rainwater flows into the rain gutter 20 from the two corrugated slate roofing materials 10. If the water level of the rainwater from the lower surface of the inside of the rain gutter 20 does not exceed the height of the rain gutter 20, the rainwater will be drained through the rain gutter 20. However, as shown in Fig. 10, when the rain gutter 20 is provided between two corrugated slate roofing materials 10, a gap will be created between the corrugated slate roofing material 10 and the rain gutter 20 due to the unevenness of the corrugated slate roofing material 10.
[0012] When the rainwater level rises, as shown in FIG. 11, the water exceeds the gutter 20 and overflows from the gap between the corrugated slate roof material 10 and the gutter 20, causing a leak.
[0013] (First embodiment) In this embodiment, in order to prevent overflow from the gap between the corrugated slate roofing material 10 and the rain gutter 20 shown in FIG. 11, the rain leakage prevention member 30 of the first embodiment shown in FIG. 1 is used. FIG. 1 is a front view showing one configuration example of the rain leakage prevention member of the first embodiment of the present invention. In FIG. 1, 30A indicates the upper side, 30B indicates the lower side, and 30C and 30D indicate the side sides. As shown in FIG. 1, the rain leakage prevention member 30 has a corrugated unevenness formed on the upper side 30A in the length direction in accordance with the corrugated unevenness of the corrugated slate roof material 10. As shown in FIG. 2, by inserting a plurality of convex parts of the rain leakage prevention member 30 into a plurality of concave parts on the underside of the corrugated slate roof material 10, the concave parts on the underside of the corrugated slate roof material 10 are blocked as shown in FIG. As a material for the rain leakage prevention member 30, for example, Galvalume steel sheet (registered trademark) is used. Galvalume steel sheet is characterized by its rust resistance, excellent durability, and light weight, and is preferably used as the rain leakage prevention member 30. However, the material for the leakage prevention member 30 is not limited to Galvalume steel sheet, and other materials may be used.
[0014] Then, as shown in Fig. 4, the underside of the corrugated slate roofing material 10 and the upper edge 30A of the leak prevention member 30 are bonded with adhesive 40. The sides 30C, 30D and the lower edge 30B of the leak prevention member 30 are also bonded to the gutter 20 with adhesive 40. Fig. 4 is a cross-sectional view showing the state in which the underside of the corrugated slate roofing material 10 is bonded to the upper edge 30A of the leak prevention member 30, and the lower edge 30B of the leak prevention member 30 is bonded to the gutter 20.
[0015] By bonding the underside of the corrugated slate roofing material 10 to the upper edge 30A of the leak prevention member 30, the gap between the corrugated slate roofing material 10 and the rain gutter 20 is closed, and overflow can be prevented. The side edges 30C, 30D and the lower edge 30B of the leak prevention member 30 are bonded to the rain gutter 20 with adhesive 40 because the gap between the leak prevention member 30 and the rain gutter 20 is closed, further improving the effect of preventing overflow. However, the side edges 30C, 30D and the lower edge 30B of the leak prevention member 30 do not have to be bonded to the rain gutter 20 with adhesive 40. The same applies to the second embodiment described later.
[0016] In addition, since there is an effect of preventing overflow by bonding at least one side of the rain leakage prevention member 30, excluding the upper side 30A, to the rain gutter 20 with the adhesive 40, it is not necessary to bond all sides of the rain leakage prevention member 30, excluding the upper side 30A, to the rain gutter 20 with the adhesive 40. The same applies to the second embodiment described later. When two or more rain leakage prevention members 30 are arranged side by side, adjacent sides of adjacent rain leakage prevention members 30 are bonded together with adhesive 40. This is the same in the second embodiment described later.
[0017] FIG. 5 is a cross-sectional view showing the effect of preventing rain leakage when a rain leakage prevention member is used on a corrugated slate roof. As shown in Figure 5, the gap between the two corrugated slate roofing materials 10 and the rain gutter 20 is blocked by the rain leak prevention member 30. Even if the water level rises above the height of the rain gutter 20, as shown in Figure 11, water will not overflow beyond the gutter 20 and will flow through the gap between the corrugated slate roofing materials 10 and the rain gutter 20, preventing rain leaks.
[0018] Second embodiment When bonding the underside of the corrugated slate roofing material 10 and the upper edge 30A of the leak prevention member 30 with adhesive 40, in order to keep the multiple convex parts of the leak prevention member 30 inserted into the multiple concave parts of the underside of the corrugated slate roofing material 10, it is necessary to support the leak prevention member 30 so that it does not fall. Below, a second embodiment of a leak prevention member that can be fixed by hanging it on the corrugated slate roofing material 10 will be described.
[0019] Fig. 6 is a front view showing one example of the configuration of the rain leakage prevention member of the second embodiment of the present invention, in which 31A indicates an upper side, 31B indicates a lower side, and 31C and 31D indicate side sides. The leak prevention member 31 shown in Fig. 6 has a protrusion 31AA on at least one of the multiple protrusions on the upper side 31A of the leak prevention member 31. The protrusion 31AA is "T" shaped, and by bending the protrusion 31AA from the lower surface to the upper surface of the corrugated slate roofing material 10 into a "U" shape as shown in Fig. 7, it can be attached to the end of the corrugated slate roofing material 10 as shown in Fig. 8. In this state, the lower surface of the corrugated slate roofing material 10 and the upper side 31A of the leak prevention member 31 are bonded with adhesive 40, and the side edges 31C, 31D and the lower side 31B of the leak prevention member 31 are bonded with the rain gutter 20 by adhesive 40. In this way, as shown in Figure 9, while keeping the multiple convex portions of the rain leak prevention member 31 inserted into the multiple concave portions of the underside of the corrugated slate roofing material 10, the underside of the corrugated slate roofing material 10 can be bonded to the upper edge 31A of the rain leak prevention member 31, and the side edges 31C, 31D and lower edge 31B of the rain leak prevention member 31 can be bonded to the rain gutter 20.
[0020] Although the above-described embodiments are preferred embodiments of the present invention, the scope of the present invention is not limited to the above-described embodiments, and the present invention can be implemented in various modified forms without departing from the gist of the present invention.
[0021] For example, the roofing material on which the continuous unevenness is formed is not limited to a corrugated slate roofing material, but may be a metal corrugated roof. Furthermore, in the second embodiment, the protruding portion is "T" shaped, but is not particularly limited to this shape and may be, for example, rectangular. [Explanation of symbols]
