関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an asphalt sheet that can be used for multiple purposes such as civil engineering and construction, and in particular, a relatively thick and bulky nonwoven fabric sheet is impregnated with asphalt in half of its thickness. The present invention relates to an asphalt sheet in which the remaining half is in the form of a hollow cavity not impregnated with asphalt, and the unimpregnated portion is impregnated with latex mortar.

は建築物の防水層として使用するものであつた。 Conventionally, this type of asphalt sheet, mainly used for roofing, has a base material of roofing paper or thin non-woven fabric made of short fibers, and is mainly a single-layer sheet impregnated with asphalt. It was used as a waterproof layer.

ら施工することが普通とされていた。 For this reason, conventional asphalt roofing has a thickness of around 1 mm, and although it has some tensile strength, when used for waterproofing the roof of a building, it is difficult to prevent cracks that occur in the underlying concrete. They were unable to keep up with the water vapor pressure generated from the concrete layer, causing ruptures and water leaks. For this reason, it was common practice to construct asphalt roofing by laminating two or three layers together.

た。 Furthermore, when the roof slab surface is formed using cast-in-place concrete, this waterproof layer can only be constructed after a certain period of time has passed since the construction is carried out after the concrete has been cured and dried.

ントモルタルが適当である。 The asphalt sheet of the present invention uses a nonwoven fabric base material made of long fibers of relatively thick and bulky synthetic fibers, for example, a nonwoven fabric with a thickness of about 4 to 6 mm, and half of the thickness of the nonwoven fabric is impregnated with asphalt. An asphalt sheet in which the remaining unimpregnated area is impregnated with latex mortar,
As mentioned above, this latex can replace the conventional waterproofing method of laminating two or three layers with just one layer, and has a latex mortar layer that has good affinity with the underlying concrete layer. When using the mortar-impregnated surface as the contact surface with the base concrete, asphalt can be used to shorten the construction period by taking advantage of its affinity and can be applied even when the base concrete layer is in a semi-hardened, uncured state. It provides sheets. The asphalt used in the present invention includes not only blown asphalt but also rubber asphalt,
Various asphalts such as modified asphalt can be used, and cement mortar mixed with rubber or synthetic resin, which is flexible even after hardening, is suitable as the latex mortar.

完全に密接させるものとする。 To explain the asphalt sheet of the present invention with reference to the accompanying drawings, the figure shows a cross-sectional view of the asphalt sheet of the present invention, and 1 is a bulky nonwoven fabric base having an appropriate thickness made by needle punching and randomly entangling long synthetic fibers. In the present invention, asphalt 2 is impregnated from one side to half of the thickness of the nonwoven fabric 1, the remaining half is made into a hollow part, and the other half of the layer of this hollow part is impregnated with asphalt 2. Impregnate latex mortar 3 from the surface,
The intermediate layer of the non-woven fabric 1 is made to be in close contact with each other so that no unimpregnated portion remains.

る。 As mentioned above, the asphalt sheet of the present invention is a thick non-woven fabric base material with one side impregnated with asphalt and the other side impregnated with latex mortar, so it can be used to waterproof concrete slab surfaces on rooftops of buildings. Conventionally, in construction, concrete hardens and is applied in two or three layers, which takes a long time. However, when using the asphalt sheet of the present invention, a sufficient waterproofing effect can be obtained by pasting only one layer, and the construction period of the present invention was delayed. The asphalt sheet has a latex mortar layer on one side that has good affinity with the base concrete layer, so when this latex mortar-impregnated surface is used as the contact surface with the base concrete, use this affinity to make the base The construction period is shortened because construction can be performed even when the concrete construction surface is uncured or wet. Since the nonwoven fabric of the base material is made of long synthetic fibers entwined randomly, it can withstand fluctuations such as cracks in the underlying concrete, and has particularly strong properties against tensile fractures, and can be expected to be completely waterproof. This has an epoch-making effect.
