［考案の背景と目的］
本考案は新規な防水シート施工構造物を提供す
ることにある。[Detailed description of the invention] [Background and purpose of the invention] The purpose of the invention is to provide a new waterproof sheet construction structure.
防水シートは建物の屋上防水、屋根防水、廃棄
物埋立場、美観人工池等に広く用いられている。 Tarpaulin sheets are widely used for roof waterproofing of buildings, roof waterproofing, waste landfills, aesthetic artificial ponds, etc.
防水シートの施工においては、施工駆体、例え
ばコンクリート面に防水シートを完全に接着さ
せ、そして施工後においては防水シートのふくれ
不良が生じないことが要求される。コンクリート
面に施工した防水シートがふくれるのは、コンク
リート面と防水シート間に残存または侵透した水
分が周囲温度上昇により気化し、更に気化した水
蒸気が熱膨脹して防水シートをふくれさせるもの
である。 When constructing a tarpaulin sheet, it is required that the tarpaulin sheet be completely adhered to the construction material, for example, a concrete surface, and that the tarpaulin sheet should not bulge after construction. The reason why a waterproof sheet installed on a concrete surface swells is because moisture remaining or penetrating between the concrete surface and the waterproof sheet evaporates due to an increase in ambient temperature, and the vaporized water vapor expands thermally, causing the waterproof sheet to swell.
このため、防水シートの施工に当つてはコンク
リート面をきれいに清浄化すると共に、よく乾燥
することが必要である。しかしながらコンクリー
ト面の乾燥を十分に行なつたとしても、接着した
防水シートの水蒸気ふくれ不良を完全に防止でき
ないものである。 Therefore, when installing a waterproof sheet, it is necessary to thoroughly clean the concrete surface and dry it thoroughly. However, even if the concrete surface is sufficiently dried, it is not possible to completely prevent water vapor blistering of the adhered waterproof sheet.
このため防水シートそのものに水分除去層を設
けた水分除去層付き防水シートが用いられるよう
になつてきている。この種の水分除去層付き防水
シートとしては、防水シートの下面側、即ち防水
シートの接着面側に凹凸面のあるシートをはりつ
けてあるものが用いられている。第１図はこの種

である。第１図において１は防水ゴムシート、２
は発泡ポリエチレンシート、３は水分脱気シート
層である。この種の水分脱気シート層３が付いた
防水シートは突起部４の凹凸の溝により水分を脱
気させるものである。 For this reason, waterproof sheets with a moisture removal layer, in which a moisture removal layer is provided on the waterproof sheet itself, have come to be used. As this type of waterproof sheet with a water removal layer, a sheet having an uneven surface is attached to the lower surface of the waterproof sheet, that is, the adhesive side of the waterproof sheet. FIG. 1 shows one type of this type of waterproof sheet with a moisture removal layer. In Figure 1, 1 is a waterproof rubber sheet, 2
3 is a foamed polyethylene sheet, and 3 is a moisture degassing sheet layer. This type of waterproof sheet with a moisture degassing sheet layer 3 evacuates moisture through the uneven grooves of the protrusions 4.
しかしながら、この種のエンボスシート３が付
いた防水シートの接着面は、エンボス凸部の先端
に限られるため接着面積が著しく減少し、その結
果防水シートとコンクリート間の接着力が大きく
低下する。 However, since the adhesive surface of the waterproof sheet with this type of embossed sheet 3 is limited to the tip of the embossed convex portion, the adhesive area is significantly reduced, and as a result, the adhesive force between the waterproof sheet and concrete is greatly reduced.
本考案はかかる点に立つて為されたものであつ
て、その目的とするところは水分除去性が良好で
しかも接着力が優れた防水シート施工構造物を提
供することにある。 The present invention has been developed based on this point, and its purpose is to provide a waterproof sheet-constructed structure that has good water removal properties and excellent adhesive strength.
［考案の概要］
本考案の要旨とするところは、複数ケの水分脱

穴より中空突起内へ含浸接着して成ることを特徴
とする防水シート施工構造物にある。[Summary of the invention] The gist of the invention is to provide a waterproof sheet construction structure in which a plurality of waterproof sheets with moisture degassing protrusions are adhered to the surface of a substrate via an adhesive. At least 7% or more of the plurality of moisture degassing protrusions of the waterproof sheet with air-releasing protrusions shall consist of perforated hollow protrusions, and shall be impregnated and bonded into the hollow protrusions through the holes of the perforated hollow protrusions. A structure constructed using a tarpaulin sheet is characterized by:
本考案において、水分脱気用突起部付き防水シ
ートの複数ケの水分脱気用突起部の内の少なくと
も７％以上を穴開き中空突起部としたのは、７％
以下では接着剤を含浸したときの防水シートと駆
体表面との接着力が十分でないためである。中空
突起部の穴の位置は接着剤が含浸し、該含浸接着
剤が中空突起部と駆体面間とを接着できる位置な
らよく、例えば中空突起部の先端または側面であ
る。また、穴の形状は接着剤が含浸できるものな
ら特に限定されるものではない。なお、この材質
はプラスチツクならどれでもよい。 In the present invention, at least 7% of the plurality of moisture degassing protrusions of the waterproof sheet with moisture degassing protrusions are hollow protrusions with holes.
This is because the adhesion between the waterproof sheet and the surface of the substrate is insufficient when impregnated with the adhesive. The position of the hole in the hollow protrusion may be any position where it can be impregnated with adhesive and the impregnated adhesive can bond the hollow protrusion and the substrate surface, such as the tip or side surface of the hollow protrusion. Further, the shape of the hole is not particularly limited as long as it can be impregnated with the adhesive. Note that this material may be any plastic.
本考案において用いられる接着剤は、中空突起
部材と駆体との二者を接着し、穴開き中空突起部
への含浸性がよいものならどのようなものでもよ

接着剤、エポキシ樹脂接着剤などがある。また、
これらの接着剤は用途により種々な接着剤が市販
されているので、それらを適宜用いることができ
る。 The adhesive used in the present invention may be any adhesive that adheres the hollow protrusion member and the precursor and has good impregnation properties into the hollow protrusion, such as chloroprene rubber adhesive, nitrile adhesive, etc. There are rubber adhesives, acrylic resin adhesives, phenolic resin adhesives, epoxy resin adhesives, etc. Also,
Various types of adhesives are commercially available depending on the intended use, so any one of them can be used as appropriate.

い値であつた。 FIG. 2 is a sectional view showing an embodiment of the waterproof sheet construction structure of the present invention. In Figure 2, 8
is a waterproof rubber sheet with protrusions for moisture degassing in which 50% of the protrusions for moisture degassing are provided with perforated protrusions, 1 is a waterproof rubber sheet layer, 2 is a foamed polyethylene sheet layer, 3 4 is a moisture degassing layer, 4 is a moisture degassing protrusion, 20 is a hollow protrusion with a hole for moisture degassing, 5 is an adhesive, 6 is concrete, and 7 is a moisture degassing groove. As shown in FIG. 2, the adhesive 5 is impregnated around the tip of the moisture degassing protrusion 4 and around and inside the tip of the moisture degassing hollow protrusion 20, so that the moisture is removed. The waterproof sheet 8 with projections and the concrete 6 can be firmly bonded to each other through an adhesive. The adhesive strength in this embodiment of the present invention was 1.8 times higher than the adhesive strength in the case without the perforated hollow protrusion 20 for moisture degassing.

The adhesive strength is the adhesive strength when there is no hollow protrusion 20 with holes for moisture degassing.
It was 1.08 times, and the adhesive strength hardly improved.
