[0015] [Figure 1] FIG. 1 is a cross-sectional view of an interior wall panel. [Figure 2] FIG. 2(a) is an explanatory diagram before the renovation, and FIG. 2(b) is an explanatory diagram after the renovation. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, as an embodiment of the present invention, an interior wall panel for bathroom renovation that is attached to the interior wall of an existing bathroom will be described.

[0017] As shown in Figure 1, the interior wall panel 1 is made of a laminate including, in order from back to front, a lower layer board 2, an intermediate layer sheet 4, and a surface layer sheet 6. An adhesive layer 3 is formed on the back surface of the intermediate layer sheet 4 by coating, printing, etc., and the intermediate layer sheet 4 is attached to the surface of the lower layer board 2 via the adhesive layer 3. An adhesive layer 5 is formed on the back surface of the surface layer sheet 6 by coating, printing, etc., and the surface layer sheet 6 is attached to the surface of the intermediate layer sheet 4 via the adhesive layer 5.

[0018] The lower board 2 is a board made of one or a combination of two or more of a synthetic resin board, a calcium silicate board, and a wood board. That is, the lower board 2 may be a synthetic resin board, a calcium silicate board, a wood board, or a plywood of a synthetic resin board and a calcium silicate board. As the synthetic resin, an appropriate material can be selected from known materials such as vinyl chloride resin, polyolefin resin, polystyrene resin, polyester resin, polyamide resin, polycarbonate resin, acrylic resin, urethane resin, fluorine resin, epoxy resin, and ABS resin. As an example, the lower board 2 is a board made of vinyl chloride resin (vinyl chloride resin board). Note that vinyl chloride resin refers to a resin whose main component is a unit derived from vinyl chloride.

[0019] The lower plate 2 has a thickness of 1 mm or more, or 1.5 mm or more, or 2 mm or more. The lower plate 2 has a thickness of 14 mm or less, or 12 mm or less, or 6 mm or less, or 4 mm or less. For example, the thickness of the lower plate 2 is 1.2 mm.

[0020] The intermediate layer sheet 4 is made of synthetic resin containing magnetic powder. The magnetic material is a magnetic powder or granule, and an appropriate material can be selected from known materials such as iron, iron oxide, cobalt, and nickel. For example, the magnetic material is iron powder. The synthetic resin is the same as the synthetic resin of the lower layer plate 2. For example, the intermediate layer sheet 4 is made of vinyl chloride resin containing dispersed iron powder (iron powder-containing vinyl chloride resin sheet). In this case, for example, the intermediate layer sheet 4 is obtained by molding a mixture of vinyl chloride resin with an appropriate amount of plasticizer and stabilizer added to it into a sheet with 50% to 90% by mass of iron powder based on the total mass of the resin using a molding machine.

[0021] The intermediate layer sheet 4 is thinner than the lower layer sheet 2. The intermediate layer sheet 4 has a thickness of 0.1 mm or more, or 0.2 mm or more, or 0.3 mm or more. The intermediate layer sheet 4 has a thickness of 0.8 mm or less, or 0.5 mm or less, or 0.4 mm or less, or 0.3 mm or less. For example, the thickness of the intermediate layer sheet 4 is 0.2 mm or 0.4 mm.

[0022] The surface sheet 6 is a sheet made of synthetic resin. The surface sheet 6 forms the design of the wall surface and is also called a decorative sheet. The surface sheet 6 has a printed layer. The synthetic resin is the same as that of the lower board 2. As an example, the surface sheet 6 is a sheet made of vinyl chloride resin (vinyl chloride resin sheet).

[0023] The surface layer sheet 6 is a sheet thinner or thicker than the intermediate layer sheet 4. The surface layer sheet 6 has a thickness of 0.1 mm or more, or 0.2 mm or more, or 0.3 mm or more. The surface layer sheet 6 has a thickness of 0.8 mm or less, or 0.5 mm or less, or 0.4 mm or less, or 0.3 mm or less. For example, the thickness of the surface layer sheet 6 is 0.2 mm.

[0024] The configuration of the interior wall panel 1 according to this embodiment is as described above. Next, a construction method for bathroom renovation will be described.

[0025] FIG. 2(a) shows the relationship between a bathtub B and an interior wall panel P in an existing bathroom. As shown in FIG. 2(b), in bathroom renovations, the interior wall panel P is not replaced, but a new interior wall panel 1 is attached on top of the interior wall panel P. That is, an adhesive layer 7 is formed on the back surface of the interior wall panel 1 (the back surface of the lower board 2) by coating, printing, etc., and the interior wall panel 1 is attached to the surface of the interior wall panel P via the adhesive layer 7. Alternatively, double-sided tape may be used instead of an adhesive.

[0026] Before attaching the interior wall panel 1, clean and remove any dirt from the installation surface (surface of the interior wall panel P). If the interior wall of the existing bathroom is not panel P but is instead tiled or painted, and there is loose tile or peeling paint, the surface must be primed. Also, if there are large irregularities in the installation surface, back-up material is filled in to smooth out the concave parts, and the convex parts are removed by scraping or cutting to make them smooth.

[0027] Once the base preparation is complete, the interior wall panel 1 is processed. The interior wall panel 1 is cut to fit the existing size while taking measurements on-site. This can be done using a manual cutting tool such as a cutter knife or scissors without using an electric saw, so no noise or dust is generated. Note that cutting is not limited to cutting the interior wall panel 1 in half with a manual cutting tool such as a cutter knife or scissors, but also includes making a linear cut on the surface of the interior wall panel 1 with a manual cutting tool such as a cutter knife or scissors and splitting the interior wall panel 1 using this as a score line.

[0028] Waterproofing is performed after the interior wall panel 1 is attached. That is, caulking 8 is applied to the edge of the interior wall panel 1. Once the waterproofing is complete, the adhesive and caulking are left to cure until they are completely hardened, and then the construction is complete.

[0029] As described above, the interior wall panel 1 according to this embodiment has a certain degree of rigidity, yet can be easily cut, and magnet-fixed fixtures can be used.

[0030] Specifically, i) by providing a plate (lower layer plate 2), a certain degree of rigidity can be imparted to the interior wall panel 1, ii) by setting the thickness of the three layers (lower layer plate 2, middle layer sheet 4 and surface layer sheet 6) as described above and by using polyvinyl chloride resin for all of them, the interior wall panel 1 can be easily cut, and iii) by including a magnetic material in the sheet (middle layer sheet 4), it is possible to fasten magnetically fixed fixtures.

[0031] According to the interior wall panel 1 of this embodiment, for example, all three layers (the lower layer board 2, the middle layer sheet 4, and the surface layer sheet 6) are made of vinyl chloride resin. Vinyl chloride resin has excellent mechanical strength, weather resistance, heat resistance, and chemical resistance, and can be easily cut with a manual cutting tool such as a utility knife or scissors. It also has the characteristics of being flame-retardant, electrically insulating, and chemical-resistant. Furthermore, by using vinyl chloride resin as the material for the entire interior wall panel 1, a mono-material construction is achieved, reducing the environmental impact.

[0032] According to the interior wall panel 1 of this embodiment, the thickness of the entire laminate is 7 mm or less, 5 mm or less, or 4 mm or less. This prevents the surface of the interior wall panel 1 from protruding beyond the outer flange of the bathtub B, as shown in Figure 2(b). Therefore, the interior wall panel 1 of this embodiment can be finished in an appropriate condition for renovation.

[0033] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0034] In the above embodiment, the interior wall panel for bathroom renovation has been described. However, the present invention is not limited to this. It may be used for renovations other than bathrooms, or it may be used for new construction instead of renovations.

[0035] In the above embodiment, the laminate is composed of three layers. However, the present invention is not limited to this. Other layers may be added as long as the above-described effects are not impaired. [Explanation of symbols]
