ト部分の防水に難点がある。Conventionally, waterproofing methods for such building structures include a coating film waterproofing method in which a viscous liquid such as rubber asphalt or urethane elastomer is applied to a primer-treated mortar or concrete base to form a waterproof coating; Alternatively, a sheet waterproofing method is known in which a waterproof sheet such as a rubber asphalt sheet or asphalt roofing is laid on the above-mentioned base. However, with the former waterproofing method, a seamless waterproof layer can be formed, resulting in an aesthetically pleasing waterproof surface, but on the other hand, it is difficult to form a waterproof layer with a uniform thickness, and pinholes are likely to occur ( There is a difficulty in forming a complete waterproof layer.Also, with the latter sheet waterproofing method, although it is easy to form a waterproof layer of uniform thickness, there is a difficulty in waterproofing the lap or joint portion of the sheet.
そこでシートと塗膜を組合せた複合防水工法についても
種々検討されているが、未だ完全な防水工法は確立され
るに至っていないのが現状である。Therefore, various composite waterproofing methods that combine sheets and paint films have been studied, but the current situation is that no complete waterproofing method has been established yet.
その理由としては、シート材料は一般にゴムアスファル
トシートやアスファルトルーフィングが使用されるが、
これらは熱可塑性物質であり、その寸法安定性は極めて

膨張係数の相違があり、その接合界面において“そり”
や“ずれ”を生じ、やがては膨潤や亀裂の原因となり、
密着追従性のよい防水層が得られないなどの問題が挙げ
られる。The reason for this is that rubber asphalt sheets and asphalt roofing are generally used as sheet materials;
These are thermoplastic materials and have very poor dimensional stability, so reinforcing materials such as polyester fibers are often mixed into the sheets. On the other hand, since many coating film materials are thermosetting resins, there is a difference in linear expansion coefficient between the two based on the temperature difference, and "warping" occurs at the bonding interface.
This causes "slippage" and eventually causes swelling and cracks.
Problems include the inability to obtain a waterproof layer with good adhesion followability.
そこで、ゴムアスファルトシートには相容性の良好なゴ
ムアスファルトエマルジョンの塗膜を形成させる等の方
法で密着性のよい防水層の形成に成功した例もあるが、
反面ゴムアスファルトエマルジョンではウレタン塗膜の
ように耐久性、外観等のすぐれた塗膜が得られないとい
う欠点がある。Therefore, in some cases, a waterproof layer with good adhesion has been successfully formed on rubber asphalt sheets by methods such as forming a coating film of rubber asphalt emulsion with good compatibility.
On the other hand, rubber asphalt emulsions have the disadvantage that they cannot provide coatings with excellent durability, appearance, etc., like urethane coatings.

点がある。In addition, when urethane paint is applied to a rubber asphalt sheet, in addition to the above-mentioned warpage and slippage of the paint film, the solvent used in the urethane paint dissolves the rubber asphalt sheet, resulting in a stable waterproof layer. There are also problems in that acrylic paints are more likely to deteriorate than urethane paints.

て劣化し易いなどの問題点がある。Another method is known in which a foamed polyethylene sheet is used instead of a rubber asphalt sheet and a urethane paint is applied to the sheet, but even in this method, the adhesion of the urethane coating to the sheet is poor. , based on the temperature difference (because it cannot absorb the difference in expansion coefficient, it is not sufficient, and due to the insulation effect of foamed polyethylene, the coating film is heated to high temperatures in summer etc., causing thermal fatigue, hydrolysis, etc.) There are problems such as easy deterioration.

工法を提供することを目的とする。The present invention has been made by focusing on the various problems mentioned above in conventional waterproofing methods, and is a composite waterproofing method in which a urethane coating film, which is conventionally superior in quantity as a waterproofing coating film, is combined with a rubber asphalt sheet. Therefore, there is no warpage or misalignment between the paint film and the sheet surface at the coating interface.
The purpose is to provide a waterproofing method for architectural structures that is stable and durable over a long period of time.

防水工法である。That is, as shown in FIG. 1, in the present invention, a rubber asphalt sheet 3 with a nonwoven fabric 4 adhered to the upper surface is laid on a base 1 which has been subjected to a primer treatment 2 if necessary, and a urethane resin is placed on the nonwoven fabric 4. A waterproofing construction method for a building structure characterized by forming a coating layer 5, and as shown in FIG. This is a waterproofing method for architectural structures, characterized in that an acrylic rubber coating layer 6 is formed thereon.

便利である。As the rubber asphalt sheet 3 used in the waterproofing method of the present invention, a commercially available product with a thickness of 0.2 to 5 mm can be used as is, and as the nonwoven fabric 4, natural or synthetic long fibers or For example, polyester nonwoven fabric, polypropylene nonwoven fabric, etc., which are bulky and have dimensional deformability, heat resistance, flexibility, etc., and are manufactured using staple fibers, are used. This nonwoven fabric is used in the form of a sheet with a thickness of 0.4 to 3.0 + u, but it is convenient for construction if it is adhered to the top surface of the rubber asphalt sheet 3 in advance by means such as rolling pressure. be.

By applying g to form a flexible coating film thickness, the adhesiveness with the urethane coating layer 5 can be further improved.

。In the waterproofing method of the present invention, the urethane coating layer 5 is not directly formed on the surface of the rubber asphalt sheet 3;
It is applied and formed via a nonwoven fabric 4 that is adhesively fixed to the upper surface of the rubber asphalt sheet 3. Due to its flexibility and dimensional deformability, the nonwoven fabric 4 expands due to the temperature difference at the bonding interface between the urethane coating and the rubber asphalt sheet. It has the effect of easily absorbing the difference in coefficients, completely preventing the occurrence of warpage or deviation in that part, and significantly improving adhesion.

It has the effect of preventing seepage and preventing dissolution and deterioration of the rubber asphalt sheet 3.

When forming an excellent urethane coating on the surface of a rubber asphalt sheet, it is formed via a non-woven fabric layer, so warping or shifting at the bonding interface between the urethane coating and the rubber asphalt sheet is completely prevented. A stable urethane coating can be formed over a long period of time without causing swelling, swelling, or cracking. Further, the surface of the coating film can be finished smooth and uniformly, and the lap and joint portions of the sheet can be particularly well finished. Furthermore, even on the rising surface, a uniform finish can be achieved without causing the coating film to slip off. In addition, the solvent of urethane paint is absorbed by the nonwoven fabric layer,
The underlying rubber asphalt sheet should be safely protected.

Advantages such as being able to completely prevent leakage can be obtained.
