必要があつた。(Prior art) A typical conventional waterproof sheet is a rubberized asphalt sheet. This sheet is made of a mixture of rubber and asphalt, has appropriate elasticity, and has excellent durability and weather resistance. Because of this, it is widely used in various waterproofing constructions. However, on the other hand, this sheet is vulnerable to external damage and it was necessary to take sufficient care not to damage it during construction.

引き起こし、防水機能を損なう欠点があつた。 On the other hand, there is another type of waterproof sheet called Alf Alto roofing material. This sheet is made by reinforcing a rubberized asphalt sheet with single fibers such as glass fiber or polyester fiber or woven fabric.
This roofing material also has low elongation, so when it is pasted onto a waterproof subsurface, it cannot follow the expansion or contraction of the subsurface, and as a result, if the subsurface water cracks or fissures, the roofing also cracks or breaks. It had the disadvantage of causing a zero span tension phenomenon and impairing its waterproof function.

By preventing damage and maintaining the waterproof function, by giving the tarpaulin appropriate rigidity and making it easier to install on flat areas, and by actively damaging some of the members that make up the tarpaulin. The present invention provides a waterproof sheet that can be easily installed in complicated areas such as entrances and exits, drains, and risers by stretching the waterproof sheet.

保持する。(Function) Therefore, the vulcanized rubber composition layer 2, the nonwoven fabric 3, and the waterproof sheet 1 of the present invention, which constitute the waterproof sheet of the present invention, are cut into 50 mm x 200 mm.
Each tensile strength at a tensile speed of 100 mm/min -
When the elongation characteristics were determined, as shown in a typical example in Fig. 2, when the waterproof sheet 1 was elongated beyond a certain value, only the nonwoven fabric 3 broke, but the rubber composition layer 2 did not deform as it was. Therefore, the waterproof sheet 1 itself does not break. Therefore, even if the nonwoven fabric 3 is destroyed due to cracks in the base after the waterproof sheet 1 is laminated to the base, the rubber composition layer 2 and the adhesive layer 4 are integrated until these layers are broken. Follows the base and maintains waterproofness.

改善できる。 On the other hand, when the basis weight of the nonwoven fabric 3 is 10 to 70 g/m 2 and accordingly, the tensile strength is 0.5 to 15 Kg/5 cm and the elongation is 1 to 10%, there are disadvantages in the waterproof sheet of the rubber composition layer 2 alone. That is, it is possible to improve the problem that the flexibility is too great and installation is difficult due to the influence of wind and the like.

By interposing a nonwoven fabric with specific physical properties, the waterproof sheet is given appropriate rigidity, making it easier to lay it on the base.
In addition, by actively damaging the nonwoven fabric, it can be easily applied to complicated areas such as entry/exit corners, drains, and rising parts of the waterproof sheet, and has the effect of improving impact resistance. .
