【Example】

Hereinafter, the present invention will be described in detail with reference to examples. FIG. 1 shows an embodiment of the present invention, in which a waterproof sheet A is made long by inserting a metal core material 3 into a sheet body 2 over the entire length.
The seat body 2 is made of a soft resin such as flame-retardant soft polyvinyl chloride.
The thickness of about 1 mm is formed by the extrusion molding of 2a, and the metal core material 3 is inserted into the center of the thickness of the soft resin 2a at the time of this extrusion molding. The metal core 3 is made of a thin aluminum plate or the like having a thickness of about 0.1 mm, and is formed to have a width smaller than the width of the sheet body 2 (for example, about 4/5 to 1/3, / 2 is preferable), the metal core 3 is not inserted into both sides of the sheet body 2, and the metal core 3 is not inserted and the portion formed only of the soft resin 2 a is formed by the nailing portions 4, 4. There are four. In addition, the seat body 2
A large number of water stopper pieces 5, 5... Are provided symmetrically with respect to the center line in the width direction of the sheet body 2, and each water stopper piece 5, 5,... Is located at the center of the sheet body 2 as shown in FIG. It is inclined so as to project obliquely upward toward the side. Here, as shown in FIG. 1, of the plurality of water stop pieces 5, the water stop piece 5 whose side end portion is closer than the water stop piece 5 at the center in the width direction of the sheet body 2 is closer. The height is formed high. The waterproofing between the opposing portions of the side edges of the roofing material 1 is performed by using the waterproofing sheet A created as described above. In FIG.
An embodiment in which a waterproof sheet A is used in a roof panel 11 formed by laying roofs is described. In other words, the construction of the roof is done by attaching a rafter on top of the main building, placing a base plate on the rafter, constructing a roof base, and then laying tiles on the base plate and roofing it. However, the work of installing a roof base and laying a large number of tiles is very complicated. Therefore, by using a roof panel 11 formed by stretching a plurality of roofing materials 1, 1... On a base plate 9 and mounting the roof panel 11 side by side on a main building or the like, as shown in FIG. The construction of the roof can be easily performed without the necessity of performing the work of laying a roof base or laying a tile plate. As shown in FIGS. 3 (a) and 3 (b), the roof panel 11 is partially overlapped with the roof material 1, 1... Is created by abutting the plurality of roofing materials 1, 1 ... with their side edges facing each other in the direction of their wives,
The base plate 9 is formed by attaching a face plate 14 above the frame 13. In this manner, the waterproof sheet A is disposed below the facing ends of the roofing materials 1, 1 whose side ends face each other. That is, after the waterproof sheet A is mounted on the base sheet 9, the roofing materials 1, 1... By attaching, the waterproof sheet A can be disposed below the opposed ends of the roofing materials 1, 1 so that even if rainwater enters between the opposed ends of the roofing materials 1, 1, the waterproof sheet A is waterproof. The water is stopped by the water stopper pieces 5 provided on the sheet A, and it is possible to prevent rainwater from entering the lower side of the roofing material 1. The fixing of the waterproof sheet A to the base plate 9 can be performed by driving a nail 8 into the base plate 9 from the nailing portion 4 of the sheet body 2 as shown in FIG. Therefore, the nail 8 does not penetrate the metal core material 3 but penetrates only the soft resin 2a. In the embodiment of FIG. 3, the side end of one roofing material 1 in the direction of the wife is shifted inward from one side edge of the base plate 9 to form an overlap portion 15 on the upper surface of the base plate 9, The side edge of the other roofing material 1 in the direction of the wife is projected outward from the other side edge of the base plate 9 as an overlapping piece 16, and is located below the side edge of one roofing material 1 from the overlapping portion 15. Apply the waterproof sheet A to the base plate 9
It is attached on top. Then, as shown in FIG.
The roof panels 11, 11 adjacent to each other are connected in the direction of the wife while the gap between the 11, 11 is closed by the roofing material 1.
In the figure, reference numeral 17 denotes a sealer for ensuring waterproofness between the roof panels 11.

【The invention's effect】

As described above, in the present invention, a metal core is inserted into the center of the soft resin sheet body in the width direction, and both end portions of the sheet body are formed as nailing portions into which the metal core is not inserted. As a result, when nailing, the nail penetrates only the soft resin that constitutes the sheet body,
The metal core material does not penetrate, so that the soft resin adheres to the nail to prevent rainwater from entering the back side of the waterproof sheet from around the nail, and that the rainwater acts on the metal core material There is no possibility that the metal core material is corroded by rainwater. In addition, since a number of water-stop pieces are provided in parallel on the upper surface of the seat body and projecting obliquely upward and diagonally toward the center in the width direction, the water-stop pieces dam the rainwater and the back of the roof material It can reliably prevent infiltration of rainwater into the water, and moreover, of the many water stoppers, the lateral end of the sheet body is closer to the side than the water stopper near the center. Since the height of the water stop piece is formed high, the center part has a low water stop piece so that the primary waterproofing that reduces the flow rate of rainwater can be performed, and the side end part has a high water stop. The piece can be made to adhere to the lower surface of the roofing material to perform secondary waterproofing, and the effect of preventing rainwater from entering by the water blocking piece can be highly obtained.
