ビルの屋上などに施工された防水シートは、下
地との間の空気などの気体の膨張により、部分的
に膨れを生ずることがある。膨れ防止のため、従
来より脱気工法及び重量物により押さえる工法な
どが知られている。
A waterproof sheet installed on the roof of a building may partially swell due to the expansion of gas such as air between it and the base. In order to prevent blistering, degassing methods and methods of pressing down with heavy objects are conventionally known.
しかし、既存の脱気工法は下記の欠点がある。 However, existing degassing methods have the following drawbacks.
(1) 通気層の重ね合わせ部分があるため、防水シ
ート表面に段差を生じ、膨れが発生し易い。(1) Because there are overlapping parts of the ventilation layers, there is a difference in level on the surface of the waterproof sheet, which tends to cause blisters.
(2) 通気層と防水シートとの接着力が弱いため、
台風などの風圧により防水シートが剥がれ易
い。(2) Because the adhesive strength between the ventilation layer and the waterproof sheet is weak,
The waterproof sheet easily peels off due to wind pressure from typhoons.
(3) 通気層を施工した上に更に防水シートを施工
しなければならず、工法が煩雑である。(3) The construction method is complicated, as it is necessary to install a waterproof sheet on top of the ventilation layer.
一方、重量物により押さえる工法では、荷重が
偏つて加わつた場合、防水シートが破損し易いと
いう欠点がある。 On the other hand, the method of pressing down with heavy objects has the disadvantage that the waterproof sheet is easily damaged if the load is unevenly applied.
また、膨れ防止性能及び防水性能の向上のた
め、下地面を硬い樹脂層で被覆した後、防水シー
トを施工する方法も提案されているが、施工が煩
雑となり実用的ではない。 Furthermore, in order to improve blistering prevention performance and waterproof performance, a method has been proposed in which a waterproof sheet is applied after covering the base surface with a hard resin layer, but this method is complicated and impractical.
本考案は、施工が容易であつて、施工後膨れを
生ずることがなく、また、優れた防水性能を有す
る脱気工法用防水シートに関する。
The present invention relates to a waterproof sheet for deaeration construction that is easy to construct, does not bulge after construction, and has excellent waterproof performance.
即ち、本考案は、ゴムアスフアルト組成物層の
片面に、アスフアルト含浸不織布が積層されてお

層された脱気工法用防水シートに関する。 That is, the present invention relates to a waterproof sheet for deaeration construction, in which an asphalt-impregnated nonwoven fabric is laminated on one side of a rubber asphalt composition layer, and a nonwoven fabric with a basis weight of 20 to 100 g/m 2 is laminated on the other side.
以下に、本考案の脱気工法用防水シートの一例
を図面に従つて詳しく説明する。 An example of the waterproof sheet for the deaeration method of the present invention will be explained in detail below with reference to the drawings.

フアルト含浸不織布、４は不織布である。 FIG. 1 is a cross-sectional view of the waterproof sheet for the deaeration method of the present invention. In FIG. 1, 1 is a waterproof sheet for deaeration construction, 2 is a rubber asphalt composition layer, 3 is an asphalt-impregnated nonwoven fabric, and 4 is a nonwoven fabric.

い。 The rubber asphalt composition layer 2 is a self-adhesive sheet mainly composed of rubber and asphalt, and its adhesive strength with the primer-coated mortar surface was measured according to ASTM D903 at room temperature (approximately 25°C). (180 degree peeling) is preferably 2 kg/cm or more.

積層することにより得られる。 The rubber asphalt composition layer 2 includes, for example, 100 parts by weight of asphalt, 2 to 100 parts by weight of rubber, and 0.
0 to 15 parts by weight of a thermoplastic resin and 0 to 70 parts by weight of an inorganic filler are added to the mixture, and 0 to 0 sulfur is added to the mixture.
A rubber asphalt composition obtained by blending ~0.25 parts by weight and heating and mixing at 120 to 200°C for 1 to 10 hours is obtained by coating and laminating one side of a nonwoven fabric impregnated with asphalt.

いられる。 The asphalt-impregnated nonwoven fabric 3 is a nonwoven fabric made of polyolefin, polyamide, polyester, polyvinyl alcohol, wool, or other fibers impregnated with asphalt. The thickness is preferably about 0.3 to 3 mm in consideration of rigidity and ease of joining. Further, the shape of the entire waterproof sheet 1 for deaeration construction is maintained mainly by the asphalt-impregnated nonwoven fabric 3, and a highly rigid nonwoven fabric with a basis weight of about 100 to 300 g/m 2 is used.

体の剛性が大きくなり、取り扱いが困難となる。 As the nonwoven fabric 4 laminated on the other side of the rubber asphalt composition layer 2, the same material as described above can be used. In particular, the resistance to cracking of the substrate,
From the viewpoint of maintaining anti-blister performance and waterproof performance over a long period of time, a nonwoven fabric made of continuous polyester fibers is preferred. In addition, the basis weight is 20~
A range of 100 g/m 2 is preferred. The weight is
When using a nonwoven fabric with a weight of less than 20 g/m 2 , the rubber asphalt composition gradually penetrates into the side of the nonwoven fabric 4 during use of the tarpaulin sheet, resulting in ventilation between the base made of the nonwoven fabric 4 and the tarpaulin sheet. air is reduced, making it impossible to maintain anti-blister and waterproof performance over a long period of time. Also, the basis weight is 100
If it exceeds g/m 2 , not only will the blistering prevention performance and waterproof performance not improve any further, but the rigidity of the entire waterproof sheet will increase, making it difficult to handle.

どの、連続した工程で製造することができる。 The waterproof sheet 1 for deaeration construction method of the present invention has an asphalt-impregnated nonwoven fabric 3 that is continuously supplied.
It can be manufactured in a continuous process, such as applying the heated and melted rubber asphalt composition 2 under flow, and simultaneously supplying and laminating the nonwoven fabric 4 on the other side of the rubber asphalt composition layer 2. .
