のゴム紛末を散布したものである。[Detailed description of the invention] This invention impregnates only one surface of a thick and bulky synthetic fiber nonwoven fabric base with asphalt, and impregnates only that surface with a synthetic resin material from the other side. This waterproof sheet has an impregnated layer formed thereon, and if necessary, rubber powder is sprinkled on the surface of the sheet to prevent adhesion.

「ふくれ」現象が生ずると防水層がはがれ、さら
にこの現象がすすむと防水層に亀裂が生じて漏水
の原因となるものである。 A commonly used waterproofing method is to attach a waterproof sheet such as asphalt roofing to waterproof the underlying concrete surface of a rooftop or flat roof. However, the biggest problem with this waterproofing method is the "bulging" phenomenon of the waterproof sheet caused by water evaporating from the underlying concrete layer. When this "blister" phenomenon occurs, the waterproof layer peels off, and as this phenomenon progresses, cracks occur in the waterproof layer, causing water leakage.

る。 The present invention provides a waterproof sheet that suppresses the "bulging" of the waterproof layer by allowing water vapor emitted from the concrete base to escape outward through a ventilation layer provided in the center of the sheet layer. be.
添付図面により本考案の防水シートを説明する
と、第１図は本考案の防水シートの断面図を示
し、第２図は必要に応じてなされる他の実施例に
よる防水シートの断面図を示す。 The waterproof sheet of the present invention will be explained with reference to the accompanying drawings. FIG. 1 shows a cross-sectional view of the waterproof sheet of the present invention, and FIG. 2 shows a cross-sectional view of a waterproof sheet according to other embodiments as required.

たゴム紛末を示すものである。 In the figure, 1 is an asphalt-impregnated layer in which asphalt is impregnated from one surface of a thick bulky synthetic fiber nonwoven fabric base material, and 2 is an asphalt-impregnated layer that is impregnated with asphalt from the other surface of the base material in the same manner as above. This shows an impregnated layer in which only the surface is impregnated with a synthetic resin material. Therefore, in the waterproof sheet of the present invention, an unimpregnated layer 3 in which the asphalt 1 and the synthetic resin material 2 are not impregnated is formed between the layers. Reference numeral 4 in FIG. 2 indicates rubber powder that is sprinkled to prevent the tarpaulin sheets from sticking together when they are rolled up and stored, and to prevent slipping during construction.
本考案の防水シートは、上記のように嵩高な厚

期待できるものであつて、従来の防水シートには
みられない実用上の効果を奏するものである。 The waterproof sheet of the present invention is made by impregnating both the front and back sides of a bulky and thick base sheet with a waterproof material as described above.
Furthermore, by providing an unimpregnated layer 3 in the middle of the base material, this unimpregnated layer 3 acts as a ventilation layer and allows water vapor generated from the base concrete to escape laterally, thereby preventing the "bulging" phenomenon of the waterproof layer. It can be expected to be completely waterproof, and has practical effects not found in conventional waterproof sheets.
