本考案はコンクリート建造物の屋根等の防水に
使用する接着防水シートの改良に関するものであ
る。[Detailed Description of the Invention] The present invention relates to an improvement of an adhesive waterproof sheet used for waterproofing the roofs of concrete buildings, etc.
コンクリート建造物の屋根を防水する場合、裏

工後、日射熱等のために下地から蒸発する水分を
スムースに脱気でき、防水シートの表面に膨れが
発生するのを確実に防止できる利点がある。 When waterproofing the roof of a concrete building, it is known that a waterproof sheet with ventilation grooves on the back is coated with adhesive and laid on a dry roof subsurface. In addition, after the tarpaulin is installed, moisture that evaporates from the base due to solar heat, etc. can be smoothly degassed, and the formation of blisters on the surface of the tarpaulin is reliably prevented. There are advantages that can be achieved.
ところで、防水シートに通気溝を設けるとその
溝深さの分だけシート厚さを厚くする必要があり
（強度保持等のため）、防水シートの重量増加のた
めに防水シートの運搬、敷設が困難になる。 By the way, when ventilation grooves are provided in a tarpaulin sheet, the thickness of the sheet must be increased by the depth of the groove (to maintain strength, etc.), which increases the weight of the tarpaulin sheet, making it difficult to transport and install it. become.
このため、本出願人は第１図に示すように防水
性シート１′の裏面に軽量シート２′、例えば発泡
ポリエチレンシートを積層し、この軽量シート
２′に通気溝３′，３′…を設けることを既に提案
した。 For this reason, the present applicant has laminated a lightweight sheet 2', for example, a foamed polyethylene sheet, on the back side of a waterproof sheet 1', as shown in FIG. 1, and provided ventilation grooves 3', 3', . I have already proposed that it be established.

As shown in the figure 4',..., an adhesive layer is provided in advance, and because of this adhesive layer, even if the adhesive applied to the base is relatively weak, the waterproof sheet cannot be attached to the base. Therefore, the adhesive layer on the base can be made to have a weak adhesiveness, allowing the worker to walk directly on the adhesive layer on the base, improving work efficiency. obtain.

力な接着は困難である。 The above-mentioned lightweight waterproof sheet also has the advantage that alignment of the sheets after being temporarily laid on the base is easy because the sheets are easy to move due to their light weight. However, when aligning this sheet, it is necessary to temporarily lay the waterproof sheet on the base coated with adhesive, then peel it off again, and then move it. At this time, the adhesive layer of the waterproof sheet tends to transfer to the base side. However, if the adhesive layer of the waterproof sheet is transferred to the base, it is difficult to strongly adhere the waterproof sheet to the base after positioning by moving the waterproof sheet.
本考案は上記の軽量防水シートにおいて、粘着
層の下地への転移を防止するものである。 The present invention is to prevent the adhesive layer from transferring to the base in the above-mentioned lightweight waterproof sheet.

る。 That is, the adhesive waterproof sheet according to the present invention is a waterproof sheet in which a lightweight sheet is laminated on the back side of a waterproof sheet, and ventilation grooves are provided on the outer surface of the lightweight sheet, and the outer surface of the lightweight sheet has an entire surface including the ventilation groove surface. This structure is characterized in that an adhesive layer is provided on the surface.
以下、図面により本考案を説明する。 The present invention will be explained below with reference to the drawings.

外面に通気溝を含む全面に設けた粘着層である。 In FIG. 2A, 1 is a waterproof sheet;
Vulcanized rubber sheets, plastic sheets, asphalt roofing, etc. can be used. 2 is a lightweight sheet, which is laminated on the back side of the waterproof sheet 1. A foamed polyethylene sheet (foaming ratio: 10 to 20 times) can be used as the lightweight sheet 2. 3,...
are ventilation grooves provided on the surface of the lightweight sheet, which are in the form of a lattice or mesh, and in the case shown, are in the shape of a tortoiseshell (the area of one tortoiseshell is approximately 1.0 cm 2 ). 4 is an adhesive layer provided on the entire outer surface of the lightweight sheet including ventilation grooves.

その界面での剥離をよく防止できる。 Figure 3 shows the state of stress at the adhesive layer-lightweight sheet interface (2-4 interface) when the waterproof sheet is peeled off again. First, it also acts on the groove-side vertical interface portion 21 adjacent to the interface portion 20, and as in the conventional example shown in FIG. 4, the horizontal interface portion 2
Compared to the case where stress acts only on 0', the stress acting on the horizontal interface can be made smaller.
Peeling at the interface can be well prevented.

After moving and aligning the sheet, the waterproof sheet can be strongly adhered to the base by roller rolling. Furthermore, since the tarpaulin sheet is a lightweight sheet, it is lightweight, and the tarpaulin sheet can be easily moved for the above-mentioned positioning.
