Abstract

PROBLEM TO BE SOLVED: To provide stable installation-fixation force of a decorative sheet 3 to a wall surface, while easily temporarily fastening the decorative sheet 3.SOLUTION: A decorative sheet is adhered-fixed to a wall backing material 2 by interposing an adhesive 4. A double-sided adhesive tape 5 having holes 6 at required intervals in the length direction is stuck to a required place of a reverse surface of the decorative sheet with its release paper 5c side as the obverse, and an aqueous type adhesive 4 is applied on the whole area of the reverse surface of the decorative sheet having the double-sided adhesive tape stuck thereon, including the inside of the hole 6 of the double-sided adhesive tape. Afterwards, the decorate sheet 3 is applied to a backing material with pressure by tearing off the release paper 5c, and the decorative sheet is temporarily fastened to the backing material by adhesive force of the double-sided adhesive tape, and is regularly fixed by hardening of the aqueous type adhesive. Since the decorative sheet is adhered to a ligneous wall backing material by using the aqueous type adhesive, moisture of the adhesive is harmless and volatilizes through its ligneous property, so that its adhesive is smoothly hardened. When hardened, the aqueous type adhesive maintains sufficient adhesive force over time.

Description

  The present invention relates to a method for attaching and fixing a decorative board such as a decorative plywood or a melamine decorative board to a wall surface, and an attachment structure thereof.

  The decorative board is a board whose surface is finished in the factory so that it can be directly touched or touched by human eyes when it is fixed on the wall, and a thin sheet of natural wood is attached to the plywood. There are natural wood decorative plywood, poly decorative veneer with polyester resin coated on plywood, printed decorative plywood with printed paper printed with grain on plywood, vinyl chloride decorative plywood with plywood laminated on vinyl, melamine decorative veneer, etc. Lauan material is often used for the plywood.

The means for attaching and fixing the decorative plate to the wall surface is usually performed by an adhesive. However, in recent years, as a countermeasure against sick house syndrome, a formaldehyde-based organic adhesive is not used, and its water-based form is less harmful. An adhesive is used. This water-based adhesive is one that volatilizes (disperses) water and cures to obtain adhesive strength, and it takes time to cure. For this reason, it is necessary to temporarily fix the decorative plate to the wall surface, and conventionally, nailing is generally used.
There is also a technology for supporting a decorative plate with a hanging metal fitting in order to cope with a decrease in the adhesive strength of temporary fixing or adhesive (see Patent Document 1, Abstract, FIG. 1).

JP-A-9-228603

The temporary fixing of the decorative plate by nailing is sufficient in terms of strength, but the nail may appear on the surface and may deteriorate in appearance, and even if it is hidden in the surface pattern, I can confirm. In addition, it is conceivable to carry out hidden nails, but it is difficult to adapt to the surface pattern of the decorative board.
The means using the hanging metal fittings is a large scale, and there are problems in terms of workability and cost as temporary fixing.

Today, water-based adhesives such as vinyl acetate resin adhesives called “woodwork bonds” have an adhesive force to obtain a sufficient mounting and fixing force to the wall surface of a decorative board. Double-sided tape is often used as a temporary fixing material.
For this reason, the double-sided tape is attached to the back surface of the decorative board, the adhesive is applied to the entire back surface of the decorative board to which the double-sided tape is attached, and the release paper of the double-sided tape is peeled off. It is conceivable to apply pressure to the wall base material with pressure, temporarily fix the decorative board to the base material with the adhesive force of double-sided tape, and fix it by curing the adhesive.
When sufficient double-sided tape is attached to the back of the decorative board as “temporary fastening”, the part where the double-sided tape is attached increases (becomes wide), and in that part, the base material of the decorative board with adhesive is applied. It will be fixed only with double-sided tape, not fixed. The adhesive strength of the double-sided tape deteriorates much faster than the adhesive, so the more the part where the double-sided tape is attached, the lower the stability of attaching the decorative board to the wall surface over time. It will be.

  This invention makes it a subject to obtain sufficient adhesive force (fixing force) by an adhesive agent, even if it uses a double-sided tape as a temporary fixing material under the above actual condition.

In order to achieve the above object, the present invention employs the double-sided tape having holes in the length direction at required intervals.
In the case of this double-sided tape with holes, when an adhesive is applied to the back surface of the decorative board, the adhesive enters the hole, and the decorative board is fixed to the wall surface with the adhesive even in the hole portion. . Adhesion and fixing in the hole is performed at the required interval over the entire length of the double-sided tape, and therefore sufficient adhesive strength can be obtained. For this reason, in addition to the adhesive fixation in parts other than a double-sided tape, the adhesive fixation in the hole is performed, and sufficient adhesive fixation strength of the whole decorative board to a wall surface can be obtained. The size of the hole and the required interval are appropriately set by experiments or the like so that sufficient adhesive fixing strength can be obtained.

  As a specific configuration of the fixing structure to the wall surface of the decorative board according to the present invention, in the fixing structure of the decorative board to the wall surface in which the decorative board is bonded and fixed to the wall base material with an adhesive, the wall base material A double-sided tape for temporary fixing is interposed between the decorative plate and the double-sided tape, and the double-sided tape has holes formed in the length direction at a required interval. The adhesive is water-based and is provided between the wall base material and the decorative plate. It is possible to adopt a configuration in which the decorative plate is fixed to the wall surface by being interposed in the entire area, and enters the holes, and the decorative plate is fixed to the wall surface in the holes.

  Further, in the method for attaching and fixing the decorative plate to the wall surface according to the present invention, the wall surface for forming the fixing structure of the decorative plate to the wall surface, in which the decorative plate is bonded and fixed to the wall base material via an adhesive In the method of attaching and fixing the decorative board to the surface, a double-sided tape having holes at required intervals in the lengthwise direction is provided at a required position on the back surface of the decorative board or a required position on the front surface of the wall base plate. Applying a water-based adhesive to the entire back surface of the decorative board to which the double-sided tape is attached, or the entire surface of the wall base plate, including the inside of the double-sided tape, The release paper is peeled off, the decorative board is applied to the base material with pressure by interposing a double-sided tape and an adhesive, and the decorative board is temporarily fixed to the wall base material with the adhesive force of the double-sided tape, and the water-based adhesive It is possible to adopt a fixed structure by hardening .

  In the fixing structure of the decorative plate to these wall surfaces, and the method of attaching and fixing the decorative plate to the wall surface for forming the structure, an aqueous adhesive is used and the decorative plate is adhered to the wall base material. The moisture is almost harmless and volatilizes through the decorative board and the wall base material, so that the adhesive is cured smoothly. Further, when cured, the water-based adhesive maintains a sufficient adhesive force over time. The water-based adhesive may be vinyl acetate resin, ethylene-vinyl acetate resin, acrylic resin, water-based polymer-isocyanate, etc., but it is acetic acid that is cheap and environmentally friendly as a “woodwork bond”. It is preferable to employ a vinyl resin system. At this time, if an adhesive having a high resin content of the vinyl acetate resin emulsion is used, the construction period can be shortened. In order to smoothly volatilize the moisture, it is preferable to use a material having excellent breathability and hygroscopicity for the decorative board and the wall base material.

  The double-sided tape is preferably attached to the back surface of the decorative board with a predetermined interval from the periphery to the inside of the decorative board. In this way, since the adhesive is applied also to the gap portion, the adhesive strength of the adhesive ensures the fixing strength of the peripheral edge of the decorative board to the base material. For this reason, the decorative board is stably fixed to the wall base material over time without fear of peeling the decorative board.

  Since this invention was comprised as mentioned above, while being able to perform temporary fixing of a decorative board easily, the stable attachment fixing force to the wall surface of a decorative board can be obtained.

  1 to 6 show one embodiment of a method for attaching and fixing a decorative board to a wall surface according to the present invention. This embodiment is shown in FIG. 6, in which a base material 2 is attached to a wall frame 1 by nailing, A decorative board 3 is attached and fixed to the surface of the base material 2. As the base material 2, a hygroscopic material such as veneer plywood or gypsum board is used. As the decorative board 3, well-known ones such as the above-mentioned natural wood decorative plywood, poly decorative board, printed decorative plywood, PVC decorative plywood, melamine decorative board and the like can be used. The decorative board 3 of this embodiment is a 2.1 kg weight Aika Industrial Co., Ltd. product name, in which a decorative paper is pasted on the surface of a veneer plywood having a horizontal length of 1820 mm, a vertical length of 910 mm, and a thickness of 2.5 mm in FIG. “Mares Board” and horizontal: 1850 mm, vertical: 935 mm, thickness: 3.0 mm, 2 mm thick melamine decorative board pasted on the surface of cork board, 3.2 kg weight Takase Co., Ltd. (Applicant): Product The name “Smart Free” was used.

In order to bond and fix such a decorative board 3 to the wall base material 2, not only the decorative board 3 but also the water-based adhesive 4 and the double-sided tape 5 shown in FIG. 5 are prepared.
The adhesive 4 may be any water-based adhesive. For example, trade name “Aika Quality One A-Q1 (S)” of Aika Industry Co., Ltd. is used. This adhesive 4 is a vinyl acetate resin emulsion adhesive, and the content (% by weight) of each component thereof is vinyl acetate resin, etc .: 40 to 44, vinyl acetate monomer: 0.3 or less, water: 56 ~ 60.
The double-sided tape 5 uses, for example, a trade name “Konishi Co., Ltd. holey double-sided tape WF003P-21” (width: 21 mm) manufactured by Konishi Co., Ltd., and an acrylic resin-based adhesive layer 5b is formed on both sides of the substrate 5a The release paper 5c is stuck on one surface, and the surface of the release paper 5c that is not stuck is wound inside in a roll shape. The double-faced tape 5 has holes 6 formed at required intervals in the length direction.

After preparing the adhesive 4 and the double-sided tape 5, as shown in FIG. 1, the decorative board 3 is turned over and placed on the floor or the like. First, as shown in FIG. As shown in FIG. 2, it sticks to the required location of the decorative board 3 back surface.
In this embodiment, the decorative plate 3 is attached over the entire length of the four edges, one in the middle of the width direction between them, and three in the three-quarters of the same length direction. The sticking location is appropriately selected in consideration of the fixing strength. For example, sticking on a diagonal line can be considered. At this time, the double-sided tape 5 at the periphery of the decorative plate 3 is stuck with a predetermined interval t from the periphery. The interval t may be determined appropriately in consideration of the adhesive strength of the adhesive 4 on the periphery of the decorative plate 3 described below, but if it is too wide, the periphery of the decorative plate 3 will be lifted before the permanent fixing of the decorative plate 3 with the adhesive 4. Since it is warped, it is appropriately set by actual work or the like so that the warp does not occur. Incidentally, if the decorative board 3 is “Mares board”, “Smart Free”, the adhesive 4 is Aika Quality One A-Q1 (S), and the double-sided tape 5 is “WF003P-21”, t = 2. ˜3 mm, more preferably t = about 3 mm.

  Next, as shown in FIG. 3, the adhesive 4 is applied over the entire back surface of the decorative board 3 with a comb iron 7. The depth of the corrugation trowel valley may be appropriately determined by actual work in order to determine the thickness of the coating layer of the adhesive 4. For example, the thickness of the coating layer of the adhesive 4 is 3 mm. Is about 3 mm. At the time of this application, the adhesive 4 is also applied to the surface of the double-sided tape 5. The application may be performed without gaps on the entire back surface of the decorative board 3, but may be intermittent or partial as long as the fixing strength is not lowered.

  In this type of construction site, an adhesive is used for bonding and fixing each building member, and a comb iron is often used as an application tool. When applying adhesive with this comb iron, the ridges and valleys of the adhesive made with the comb iron greatly affect the adhesive strength (important), allowing moisture, solvent, air, etc. to escape from the valleys. There is an effect that the adhesive is evenly adapted to the adherend. For this reason, depending on the type of the base material 2 and the type of the decorative plate 3 that is the adherend, various comb-shaped irons having an appropriate mountain-valley shape and valley depth are employed.

  When the application of the adhesive 4 is completed, the release paper 5c of the double-sided tape 5 is peeled off. Then, as shown in FIG. 4, together with the release paper 5c, the adhesive 4 applied thereon is also peeled off, and the adhesive layer 5b of the double-sided tape 5 is exposed.

Next, as shown in FIG. 6, the decorative plate 3 with the adhesive 4 and the adhesive layer 5 b of the double-sided tape 5 exposed on the back surface is applied (pressed) to the surface of the base material 2 with pressure, and the double-sided tape 5 is bonded. The decorative board 3 is temporarily fixed to the base material 2 with force (adhesive layer 5b). At this time, the double-sided tape 5 is positioned at the entire periphery or middle of the back surface of the decorative board 3 and exhibits a sufficient adhesive force as a temporary fixing. Moreover, since the base material 2 is hygroscopic, the volatilization (dispersion) of the water | moisture content from the water-type adhesive 4 is performed smoothly, and the adhesive 4 hardens | cures rapidly.
For this reason, the decorative board 3 is firmly attached and fixed to the base material 2 by the adhesive 4 without being displaced from the base material 2 even in temporary fixing. In this attached and fixed state, there is no nail or the like, and the surface (decorative surface) of the decorative board 3 appears neatly and looks good. Further, since the double-sided tape 5 on the periphery of the decorative board 3 is adhered with a predetermined interval t from the periphery, the adhesive 4 is applied to the interval t portion. Thus, the fixing strength of the peripheral edge of the decorative board 3 to the base material 2 is ensured, so that the decorative board 3 is stably fixed to the base material 2 over time without fear of peeling off the decorative board 3.

  In the above embodiment, the double-sided tape 5 and the adhesive 4 are provided on the side of the decorative board 3, but the double-sided tape 5 is adhered to a required portion of the surface to which the decorative board 3 of the base material 2 is attached and the adhesive 4 is applied. After the application, the decorative board 3 can be applied to the base material 2, and the decorative board 3 can be temporarily fixed and permanently fixed to the base material 2.

In the above embodiments, the preferred thickness of the decorative plate 3 is 3 mm or less and the same weight: 3.5 kg or less. However, the decorative plate 3 has a high adhesive force (adhesive strength) to the double-sided tape 5, such as JIS standard (Z1541). ) If one type (super strong) is used, the decorative board 3 having a thickness or weight greater than that can be temporarily fixed and firmly fixed.
The decorative board 3 includes a plywood and a single board on which various patterns are not applied. In those cases (including the decorative board 3), if the board warps tightly, use a large amount of double-sided tape 5 and place it not only on the square edge but also within it to properly stick against the warp. Of course.
