が施されている。(Prior Art) Concrete buildings are generally subjected to so-called rooftop waterproofing in order to prevent water leakage accidents caused by rain and snowfall.
この屋上防水工事は大別、下記の三種類の屋上
防水工法に分類される。 This rooftop waterproofing work is broadly classified into the following three types of rooftop waterproofing methods.
屋上防水工法１ アスフアルト防水工法
２ シート防水工法

防水工法、３ 塗膜防水工法が開発されて来た。Rooftop waterproofing method 1 Asphalt waterproofing method 2 Sheet waterproofing method 3 Paint film water spraying method The asphalt waterproofing method is the oldest method in history, but because it uses asphalt that is heated and melted, it may generate a bad odor and use fire. Due to such reasons as water leakage, contamination of the surrounding area by scattered asphalt, and difficulty in finding water leakage points, two-sheet waterproofing methods and three-painted film waterproofing methods have been developed.
シート防水工法は、伸び特性が優れている。

成長を示し、参入業者も多くなつて来ている。 The sheet waterproofing method has excellent elongation properties.
Can be constructed at room temperature. Fewer steps. Excellent weather resistance. Not easily affected by temperature.
It can also be applied to roofs with complex shapes. It is lightweight. Because it has the characteristics of not producing bad odors or polluting the surrounding area (non-polluting), it has shown significant growth in recent years, and more and more companies are entering the market.

欠点も指摘されて来ており、これら欠点の解消が
シート防水工法における急務となつている。 However, the sheet waterproofing method requires (1) precision in the base; (2) If it is stretched out or pasted to the base, breakage is likely to occur. (3) The joints between waterproof sheets tend to be weak points. (4) Disadvantages have also been pointed out, such as the tendency for "blistering" to occur due to adhesive solvent vapor and water vapor in the base, and there is an urgent need to eliminate these disadvantages in sheet waterproofing methods.
上記、欠点(3)の解消に関し、種々の提案がなさ

る。 Various proposals have been made to eliminate the above drawback (3), and representative examples include the construction methods shown in FIGS. 6 and 7. The construction method shown in Figure 6 is
The waterproof sheets 21, 21' are bonded to the waterproof base G using an adhesive 22 by a so-called wrap joint method. The joint parts of the waterproof sheets 21 and 21' are overlapped to a width of 40 to 50 mm, and the overlapped part 23 is welded with a rubber adhesive in the case of a rubber sheet, or solvent welded or heat welded in the case of a vinyl chloride sheet, and then a prevention sheet is applied. Tarpaulin sheet 2 layered on 21'
1 end is filled with a urethane-based or silicon-based elastic sealing material 24 or finished by welding with a welding rod. In this case, a belt-shaped sheet may be further stretched over the overlapping portion of the waterproof sheet 21 using an adhesive. This construction method is a typical sheet waterproofing construction method and can be said to be an excellent construction method.

殆ど解消されたと見て良い。 The construction method shown in Fig. 7 is the so-called tape joint construction method, and the waterproof sheets 31, 31'
is adhered to the waterproof base G using adhesive 32. In this case, the joints between the waterproof sheets have a butted structure. A tape-shaped unvulcanized butyl rubber sealing tape 33 is pressed onto this butt joint,
The upper surface is covered with a belt-shaped plastic sheet 34 made of a material with excellent weather resistance, and the belt-shaped sheet 34
and the joint surface parts 35, 3 with the waterproof sheets 31, 31'
5' is integrated by rubber adhesive, solvent welding, or heat welding, and urethane-based or silicone-based elastic sealing material 3 is attached to both ends of the strip sheet 34.
Filled with 6,36' or finished by welding with a welding rod. This construction method is considered to be even more reliable than the lap joint construction method shown in Figure 6, and it can be said that the above-mentioned drawback (3) has been almost eliminated by adopting this construction method.

目としてクローズアツプされて来ている。(Problem to be solved by the invention) However, rooftops using such sheet waterproofing methods, especially rooftops using vinyl chloride resin waterproof sheets, are suitable as exercise areas and rest areas, and can be used for light exercise or recreation. Although it has come to be called "another floor" that can be used for construction, the existence of overlapping parts of the tarpaulin sheets has been pointed out as a new drawback. Rubber sheets are rarely used in this way, but vinyl chloride resin waterproof sheets have a thickness of 2.0 mm to 2.5 mm, so
The thickness of this overlapping portion of the sheet cannot be ignored compared to other flat portions, and the elimination of this overlapping portion is being highlighted as a new requirement.

水シートを膨出させる結果となる。 The communicating uneven portions 2, 3, and 4 for deaeration and dehumidification play an extremely important role in the construction method of the present invention. If the waterproof base is not completely dry, and a waterproof sheet is pasted on top of it, the moisture contained in the waterproof base will rise and become water vapor between the waterproof sheet and the waterproof base, causing the waterproof sheet to dry. Exhibits the phenomenon of swelling. In addition, even if the waterproof base is sufficiently dry, if the open time of the adhesive used for attaching the tarpaulin sheet is not sufficient, the adhesive may be contained in the adhesive after adhering the tarpaulin sheet. The solvent that was present vaporizes, causing the waterproof sheet to bulge in the same manner as the moisture.

ない。 In this case, if a communicating uneven part for deaeration and dehumidification is provided, the moisture and solvent vapor will spread through the communicating uneven part and be released into the atmosphere from the deaeration plate provided at the rising part, etc. No more bulging of the tarpaulin. The shape of the degassing/dehumidifying communication uneven portion is provided as a longitudinal protrusion on the back surface of the waterproof sheet as shown in Fig. 5, but as shown in Fig. 4, it is provided in the vertical direction (longitudinal direction) and the horizontal direction (width direction). A groove may be formed in the groove. Of course, as a modification or application of these, a diagonal protrusion or a diamond-shaped concave groove structure may be used without departing from the scope of the present invention.

It will be done. Further, in the case of the ridged uneven portion shown in FIG. 5, it can be easily obtained by using an embossing roll in which ring-shaped grooves are engraved on the circumference of the embossing roll.

る。 In the case of the waterproof sheet shown in FIG. 5, the gap t is determined by the height of the ridges of the emulsion adhesive, but a range of about 0.5 to 0.6 mm is suitable.
In the case of the waterproof sheet 11 shown in FIG.
Since the recesses 13 between the holes 12 are relatively wide, the degassing and dehumidifying effects are large. The adhesive 6 is usually applied to the waterproof base surface using a comb trowel, but in this case, by aligning the combs in the width direction of the waterproof sheet, the ridges 12 and the combs of the adhesive are applied. Since they are orthogonal to each other, the deaeration and dehumidification effects become even greater.
