Modes for Carrying Out the Invention

[0017] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of the respective dimensions are different from the actual ones. Therefore, specific dimensions and the like should be determined in consideration of the following description. Also, there may be portions where the relationships and ratios of the dimensions are different between the drawings. In this specification and the drawings, elements having substantially the same functions and configurations are denoted by the same reference numerals to omit redundant description, and elements not directly related to the present invention are not shown.

[0018] (First Embodiment) The following is a diagram showing an example of the overall configuration of the wallpaper panel 1 according to the first embodiment of the present invention with reference to FIGS. 1 to 2, and FIG. 2 is an example of a cross-sectional view of the wallpaper panel 1 according to the present embodiment.

[0019] As shown in FIGS. 1 and 2, the wallpaper panel 1 according to the present embodiment has a wallpaper 10 and a gypsum board 20.

[0020] As shown in FIGS. 1 and 2, the gypsum board 20 has a front surface 20F, a back surface 20B, an upper surface 20U, a lower surface 20D, a left side surface 20L, and a right side surface 20R. Here, the front surface 20F, the back surface 20B, the upper surface 20U, the lower surface 20D, the left side surface 20L, and the right side surface 20R are determined by the orientation of the gypsum board 20 fixed to the stud. Note that the front surface 20F and the back surface 20B are a pair of surfaces having the largest area among the six surfaces. Generally, the gypsum board 20 has a substantially rectangular parallelepiped shape.

[0021] For example, the gypsum board 20 is a non-combustible gypsum board formed by covering the front and back surfaces of a gypsum core with base paper for gypsum board. For example, the pulp content of such base paper for gypsum board is in the range of 70 to 170 g / m 2 of the range.

[0022] The wallpaper 10 may be a paper-based wallpaper, a fiber-based wallpaper, a vinyl chloride resin-based wallpaper, a plastic-based wallpaper, or an inorganic-based wallpaper. Note that as the backing material, ordinary paper, flame-retardant paper, inorganic paper, woven fabric, non-woven fabric, etc. may be used.

[0023] Here, the paper-based wallpaper is a wallpaper mainly made of paper (ordinary paper, flame-retardant paper, or paper cloth).

[0024] Also, the fiber-based wallpaper is a wallpaper mainly made of organic fibers. Specifically, the fiber-based wallpaper may be a wallpaper mainly made of plant fibers or cellulose-based recycled fibers such as rayon (including blended or interwoven with chemical fibers), a wallpaper mainly made of chemical fibers (acrylic, polyester, etc.), or a wallpaper mainly made of animal fiber fabrics.

[0025] Also, the vinyl chloride resin-based wallpaper is a wallpaper mainly made of vinyl chloride resin or using 20 g / m 2 or more of vinyl chloride resin in the surface decorative layer.

[0026] Also, the plastic-based wallpaper is a wallpaper mainly made of plastics excluding vinyl chloride resin or using 20 g / m 2 or more of plastics in the surface decorative layer.

[0027] Furthermore, the inorganic-based wallpaper is a wallpaper mainly made of inorganic materials such as inorganic paper, inorganic aggregates, and glass fibers.

[0028] Also, the wallpaper 10 may include a backing layer adhered to the gypsum board 20, a synthetic resin layer made of a thermoplastic resin laminated on such a backing layer, and a stain-proof layer laminated on the surface of such a synthetic resin layer.

[0029] In the wallpaper panel 1 according to this embodiment, the wallpaper 10 is folded and attached to the gypsum board 20 with an adhesive 30 containing starch.

[0030] For example, as shown in FIG. 2, the wallpaper 10 may be folded and attached to the gypsum board 20 so as to cover the front surface 20F, the left side surface 20L, and the right side surface 20R of the gypsum board 20 with an adhesive 30 containing starch.

[0031] The inventor found that when the wallpaper panel 1 with the wallpaper 10 attached to the gypsum board 20 so as to cover only the front surface 20F of the gypsum board 20 was attached to the stud, the wallpaper 10 was likely to peel off from the gypsum board 20. Therefore, the inventor succeeded in solving such a problem by adopting the configuration as described above.

[0032] The inventor also found that when the wallpaper panel 1 with the wallpaper 10 attached to the gypsum board 20 so as to cover only the front surface 20F of the gypsum board 20 was attached to the stud, fragments of the gypsum board 20 were likely to spill from the left side surface 20L and the right side surface 20R. Therefore, the inventor succeeded in solving such a problem by adopting the configuration as described above.

[0033] Furthermore, the inventor found that when a plurality of wallpaper panels 1 with the wallpaper 10 attached to the gypsum board 20 so as to cover only the front surface 20F of the gypsum board 20 were arranged side by side and attached to the stud, the side surfaces of the gypsum board 20 would come into contact with each other, and a gap would be formed on the contact surface. Therefore, the inventor succeeded in solving such a problem by adopting the configuration as described above.

[0034] Here, as shown in FIG. 2, in the wallpaper panel 1 according to the present embodiment, the wallpaper 10 does not have to cover the upper surface 20U, the lower surface 20D, and the back surface 20B of the gypsum board 20.

[0035] Note that the wallpaper 10 may be attached to the gypsum board 20 so as to cover the front surface 20F, the left side surface 20L, and the right side surface 20R of the gypsum board 20, and also cover a part or all of the upper surface 20U, the lower surface 20D, and the back surface 20B of the gypsum board 20.

[0036] The mass of the adhesive 30 used herein is 60 g / m or less in terms of solid content 3 (the organic mass is 60 g ± 6 / m 3 or less) is preferable.

[0037] In such a case, the composition of the adhesive 30 may be a starch-based adhesive. The mass of the starch-based adhesive is 60 g ± 6 / m or less in terms of solid content 3 (the organic mass is 60 g ± 6 / m 3 or less) is preferable. Further, as the composition (mass %) of the starch-based adhesive, the starch paste is 80 ± 2 or more, and the reinforcing agent is 20 ± 2 or less. Such a reinforcing agent is either an ethylene vinyl acetate resin emulsion and a vinyl acetate resin emulsion, or a combination thereof. Note that the starch-based adhesive may not contain a reinforcing agent.

[0038] Further, the composition of the above-mentioned adhesive 30 may be a combination of the above-mentioned starch-based adhesive and a sealer made of a synthetic resin. The mass of the sealer is 10 g ± 1 / m or less in terms of solid content 3 (the organic mass is 10 g ± 1 / m 3 or less) is preferable. The synthetic resin is any one of an acrylic resin emulsion (acrylate copolymer emulsion, methacrylate copolymer emulsion), an ethylene vinyl acetate resin emulsion, and a vinyl acetate resin emulsion, or a combination thereof.

[0039] Alternatively, the mass of the adhesive 30 used herein is 40 g ± 4 / m or less in terms of solid content 3 (the organic mass is 40 g ± 4 / m 3 or less) is preferable.

[0040] In such a case, the composition of the adhesive 30 may be a methyl cellulose-based adhesive. Note that the methyl cellulose-based adhesive is also effective when paper is used as the backing layer, and particularly effective when a non-woven fabric is used as the backing layer. The mass of the methyl cellulose-based adhesive is 40 g ± 4 / m or less in terms of solid content 3The following (the organic matter mass is 40 g ± 4 / m 3 The following) is preferable. Further, as the composition (mass %) of the methylcellulose-based adhesive, methylcellulose is 80 ± 2 or more, and the reinforcing agent is 20 ± 2 or less. Such a reinforcing agent is either an ethylene vinyl acetate resin emulsion and a vinyl acetate resin emulsion, or a combination thereof. Note that the methylcellulose-based adhesive may not contain a reinforcing agent.

[0041] Further, the configuration of the above-described adhesive 30 may be a combination of the above-described methylcellulose-based adhesive and a sealer made of a synthetic resin. The mass of the sealer is 10 g ± 1 / m in terms of solid content 3 The following (the organic matter mass is 10 g ± 1 / m 3 The following) is preferable. The synthetic resin is any one of an acrylic resin emulsion (acrylate copolymer emulsion, methacrylate copolymer emulsion), an ethylene vinyl acetate resin emulsion, and a vinyl acetate resin emulsion, or a combination thereof.

[0042] For the wallpaper panel 1 having the above-described configuration, it can be attached to a steel stud (base material) using the method shown in Patent Document 1. Note that Patent Document 1 discloses a method for attaching a gypsum board to a steel stud.

[0043] Specifically, first, an adhesive is applied to the attachment surface of such a stud. Here, acrylic adhesives, rubber-based adhesive urethane adhesives, silicone adhesives, etc. can be applied to such an adhesive, and these may be applied alone or in combination of two or more.

[0044] Second, a part of the back surface 20B of the gypsum board 20 of the wallpaper panel 1 is temporarily fixed to such an adhesive.

[0045] Thirdly, a magnetic attraction jig is brought into contact with the front surface 20F of the gypsum board 20 of the wallpaper panel 1 and moved along the above-described adhesive, so that the stud is attracted by the attraction force of the magnetic attraction jig and the wallpaper panel 1 is crimped. As such a magnetic attraction jig, permanent magnets such as alnico magnets, ferrite magnets, and neodymium magnets can be applied. Here, instead of the permanent magnet as such a magnetic attraction jig, a temporary magnet such as an electromagnet may be applied.

[0046] According to the wallpaper panel 1 according to the present embodiment, since the back surface 20B of the gypsum board 20 is not covered with the wallpaper 10, it can be attached to the stud using the above-described method. When the back surface 20B of the gypsum board 20 is covered with the wallpaper 10, the stud cannot be attracted by the attraction force of the magnetic attraction jig and the wallpaper panel 1 cannot be crimped due to the wallpaper 10 attached to the back surface 20B, so the above-described method cannot be used.

[0047] Further, in the wallpaper panel 1 according to the present embodiment, if the back surface 20B of the gypsum board 20 is not covered with the wallpaper 10, steps are less likely to occur on the grounding surface of the stud, and there is an effect that it is easy to stick.

[0048] Further, the areas of the above-described front surface 20F and back surface 20B are preferably within the range of 100 mm × 100 mm on one side to 1000 mm on the short side × 3000 mm on the long side.

[0049] According to such a configuration, not only a general rectangular shape but also a special shape can be supported. For example, according to such a configuration, not only when the place where the wallpaper panel 1 is pasted is a general shape, but also when the place where the wallpaper panel 1 is pasted is a special shape (such as an end portion), the wallpaper panel 1 can be made into that shape. Further, according to such a configuration, the wallpaper panel 1 can be easily transported from the factory to the construction site.

[0050] Also, the thickness of the wallpaper 10 to be pasted on the front surface 20F, the left side surface 20L, and the right side surface 20R may be constant. According to such a configuration, the wallpaper panel 1 can be finished without steps. Also, according to such a configuration, the wallpaper panel 1 can be securely fixed by studs.

[0051] Also, the result of the wet strength test defined in JIS A 6921 for the wallpaper 10 may be 5 N / 1.5 cm or more.

[0052] Furthermore, the wallpaper 10 may be pasted on the gypsum board 20 by a laminating method. Specifically, the wallpaper 10 may be pasted on the front surface 20F of the gypsum board 20 through a laminating machine. In such a case, the wallpaper 10 is pasted so as to cover the left side surface 20L and the right side surface 20R of the gypsum board 20 by folding and winding the wallpaper 10. Note that the wallpaper 10 may be cut so as not to cover the upper surface 20U and the lower surface 20D of the gypsum board 20. For example, the end portion of the wallpaper 10 may be cut, and in the portion covering the back surface 20B, the upper surface 20U, the lower surface 20D, etc. of the gypsum board 20, it may or may not be cut depending on the length. According to such a configuration, the wallpaper panel 1 can be easily manufactured.

[0053] According to the wallpaper panel 1 according to the present embodiment, it is possible to avoid performing the operation of pasting the wallpaper 10 on the gypsum board 20 at the construction site.

[0054] At the construction site, there may be a portion where the wallpaper panel 1 cannot be pasted, and it may be necessary to paste wallpaper on such a portion. In such a case, it has been time-consuming for a craftsman to search for wallpaper with the same pattern as the pattern of the wallpaper 10 of the wallpaper panel 1 at the construction site. Also, when there is no wallpaper with the same pattern at the construction site, it is necessary to procure it at the construction site.

[0055] Therefore, by making the wallpaper with the same pattern as the wallpaper 10 pasted on the wallpaper panel 1 identifiable by identification information, the above-mentioned labor can be saved. Further, using such identification information, the wallpaper 10 on the wallpaper panel 1 can be freely selected. Here, such identification information is composed of symbols, numbers, characters, etc.

[0056] Note that such identification information is also given to the wallpaper with the same pattern as the wallpaper 10 together with the wallpaper panel 1 (wallpaper 10 or gypsum board 20). For example, such identification information may be given to the front or back surface of the wallpaper 10 or the front surface 20F or back surface 20B of the gypsum board 20 in the wallpaper panel 1.

[0057] Further, such identification information may be displayed by numbers, symbols, characters, etc. so that the worker can visually confirm the identification information at the construction site, or may be given to the wallpaper panel 1 or the wallpaper with the same pattern as the wallpaper 10 in the form of a multi-dimensional barcode or a QR code (registered trademark).

[0058] Hereinafter, an example of the construction method of the wallpaper panel 1 will be described. Note that the wallpaper panel 1 used in the following construction method is not limited to the wallpaper panel 1 according to the present embodiment, and any wallpaper panel can be used.

[0059] In the first example, first, the user (indicating any one of the donor, coordinator, and worker) acquires the identification information given to the wallpaper desired by the donor. For example, the user may acquire such identification information by scanning it with a communication mobile terminal or the like. Alternatively, the user may acquire such identification information from a website or a sample book.

[0060] Second, the user acquires the wallpaper panel 1 associated with the acquired identification information. For example, the user acquires the wallpaper panel 1 by transmitting the acquired identification information to the seller of the wallpaper panel 1 through a communication network. Here, the seller of the wallpaper panel 1 may create the wallpaper panel 1 using the wallpaper associated with such identification information according to the identification information notified by the user.

[0061] Thirdly, the worker attaches the wallpaper panel 1 to the attachment surface of the stud using an adhesive.

[0062] Fourthly, the worker attaches the above-mentioned wallpaper to the portion where the wallpaper panel 1 is not attached. At this time, when the worker attaches the above-mentioned wallpaper to the portion where the wallpaper panel 1 is not attached, after attaching a base material such as a gypsum board (examples include resin panels, wooden boards, metal plates, concrete plates, various cement plates, calcium silicate plates, boards containing hydrous inorganic substances, etc.) to the attachment surface of the stud, the wallpaper may be attached to the base material.

[0063] Note that the worker may attach the above-mentioned wallpaper to the portion where the wallpaper panel 1 cannot be attached.

[0064] Note that in such an example, the worker may attach the wallpaper panel 1 after attaching the above-mentioned wallpaper.

[0065] In the second example, firstly, the user acquires the identification information provided on the wallpaper 10 of the wallpaper panel 1.

[0066] Secondly, the user acquires the wallpaper associated with the acquired identification information.

[0067] Thirdly, the worker attaches the wallpaper panel 1 to the attachment surface of the stud using an adhesive.

[0068] Fourthly, the worker attaches the acquired wallpaper to the portion where the wallpaper panel 1 is not attached.

[0069] Note that in such an example, the worker may attach the wallpaper panel 1 after attaching the above-mentioned wallpaper.

[0070] In the third example, firstly, the worker attaches the wallpaper panel 1 to the attachment surface of the stud using an adhesive.

[0071] Second, the worker acquires the identification information provided on the wallpaper 10 of the wallpaper panel 1.

[0072] Third, the user acquires the wallpaper associated with the acquired identification information.

[0073] Fourth, the worker attaches the acquired wallpaper to a portion where the wallpaper panel 1 is not attached.

[0074] The third example assumes a case where it is found that wallpaper with the same pattern as the wallpaper 10 is required during the construction of the wallpaper panel 1, a case of wallpaper repair, etc.

[0075] Although the present invention has been described in detail using the above-described embodiments, it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented as modifications and variations without departing from the spirit and scope of the present invention as defined by the claims. Therefore, the description in this specification is for illustrative purposes and has no restrictive meaning for the present invention.
