水の機能をはたさなくなる欠点を有している。 BACKGROUND ART In recent years, urethane resin is applied directly onto concrete surfaces of tennis courts, sports fields, etc. Urethane resin has been applied to floors and rooftops to make them waterproof. For these coated urethane resin floors, 3 to 4 coats of urethane resin are applied to give cushioning properties to the floor.
It has to be repeated several times, and requires a lot of time and space for construction. In addition, since the urethane resin layer is formed directly on the concrete surface, when the moisture in the concrete expands and turns into water vapor due to the heating of the outside temperature, there is no place for the generated water vapor to escape, and this will cause the concrete to evaporate. This causes delamination between the surface and the painted urethane resin layer, causing unevenness on the floor surface.Furthermore, if the concrete cracks, the painted urethane resin layer will also crack and will no longer function as a waterproofing agent. have.

レタン樹脂床用中間シートである。 That is, the gist of the present invention is that the aluminum foil surface of the urethane resin permeation prevention layer, which is mainly made of a composite material of nylon or polyester film and aluminum foil, on a nonwoven fabric made of polyethylene or polypropylene, is interlayer bonded with an adhesive, polyethylene or polypropylene, etc. This is an intermediate sheet for coated urethane resin flooring, characterized in that it consists of a laminated sheet that is laminated together through layers and further has an adhesive layer provided on part or all of the nonwoven fabric surface.
以下、本考案の塗装ウレタン樹脂床用中間材に

め、確実にするために設けるものである。 A coated urethane resin floor intermediate sheet 1, which is an embodiment of the present invention, consists of a nonwoven fabric layer 2 made of polyethylene or polypropylene of 100 to 500 g/m 2 , a polyester or nylon film 3a with a thickness of 9 to 25 μm, and an aluminum foil 3b bonded together. A urethane resin permeation prevention layer 3 mainly made of a composite material is laminated via an adhesive 3c, and is bonded to the nonwoven fabric layer 2 via an interlayer adhesive layer 4 made of an adhesive, polyethylene, polypropylene, etc. It is made of a laminated sheet provided with an adhesive layer 5, and a release paper 6 is laminated on the surface of the adhesive layer 5. In the embodiment shown in the first figure, an adhesive layer 5 is partially provided on the nonwoven fabric layer 2, and an adhesive non-coated portion 7 is formed. Here, the adhesive non-coated portion 7 is provided to improve and ensure the degassing of gases such as water vapor generated from the underlying concrete.

Since a structure is formed in which gas such as water vapor can be degassed through the cracks, it is also possible to provide the adhesive layer 2 over the entire surface of the nonwoven fabric without forming the adhesive non-coated portion 7. However, as described above, it is preferable to provide the adhesive non-coated portion 7 to ensure degassing of gas such as water vapor.

A covering synthetic resin layer made of a thermoplastic synthetic resin layer having adhesive properties to resin may be provided. The coating synthetic resin layer is intended to increase the adhesive strength between the coated urethane resin and the coated urethane resin formed on the upper surface of the coated urethane resin floor intermediate sheet, and is made of a thermoplastic synthetic resin that has adhesive properties to the coated urethane resin. For example, urethane-based, polyester-based,

造とすることができる。 Next, FIG. 2 shows a painted urethane resin floor formed using the intermediate sheet 1 for painted urethane resin floors of the present invention. The coated urethane resin floor intermediate sheet 1 of the present invention is laminated to the base concrete 8, and the urethane resin 9 is further applied onto the coated urethane resin floor intermediate sheet 1. When pasting the coated urethane resin floor intermediate sheet 1 to the underlying concrete 8, the surface of the concrete 8 is coated with a urethane-based moisture-curing primer in advance to perform primer treatment, and then the concrete 8 and the underlying concrete 8 are coated. It is possible to improve the adhesion of the urethane resin floor intermediate sheet 1 and to increase the strength of concrete. Therefore, when applying primer treatment to 8 concrete surfaces, the primer is partially applied to the 8 concrete surfaces to create areas where no primer is applied, and the painted urethane resin is partially unadhesive. By using the floor intermediate sheet 1 and pasting the coated urethane resin floor intermediate sheet 1 on the concrete 8 so that a part of the adhesive layer does not overlap with the primer application area, gases such as steam from the base can be degassed. It is also possible to make it easier. For example, as shown in Figures 3 and 4, a primer coated area 1 of about 1 m width is applied to 8 concrete surfaces via a non-primer coated area 11 of about 10 to 50 m/m width.
0, and on top of that, an adhesive layer 5 with a width of 200 to 500 mm is provided on two surfaces of the nonwoven fabric as shown in Figures 5 and 6, with a non-adhesive part 7 having a width of 10 to 30 mm interposed therebetween, along the flow direction of the sheet. By laminating the painted urethane resin floor intermediate sheet 1 as shown in Figure 7, concrete 8 is formed.
A region 12 free of primer and adhesive may be formed on the surface, and the structure may be such that gas such as water vapor can be degassed from this region.

る。 As detailed above, the intermediate sheet for painted urethane resin floors of the present invention has thermal insulation properties, is rich in cushioning properties, does not generate unevenness, and even when there are cracks in the concrete, the urethane layer remains intact. It has the advantage of being able to form a crack-free painted urethane resin floor with a simple construction operation, and can be particularly effectively utilized when constructing a painted urethane resin floor with excellent heat insulation properties on a rooftop.
