Description

  The present invention relates to a construction structure and a construction method for a decorative material that is attached to a decorative surface of a wall of a house by adhesion to make up the wall.

Conventionally, as a construction structure of a decorative material, there is a construction structure in which an adhesive is applied to the back surface of the decorative material and adhered to a wall surface. (For example, refer to Patent Document 1.)
In such a case, there has been a problem that the position of the decorative material is shifted before the adhesive is cured, or the decorative material is lifted off the wall surface after the adhesive is cured due to the warping of the decorative material itself.

Moreover, as a construction method of the decorative material, there is also a method of sticking a double-sided tape on the back surface of the decorative material and bonding it to the wall surface. (For example, see Patent Document 2.)
However, also in this case, there was a problem that the adhesive strength of the double-sided tape was low and the decorative material was easily peeled off after the construction.
JP 2005-336924 A JP 3-84159

The present invention was made to solve the above problems, and the construction structure and construction method of the decorative material in the present invention aims to prevent the cosmetic material from shifting or floating during construction, and peeling after construction. And

  In order to achieve the above object, the present invention is a construction structure for a decorative material that is attached to a decorative surface of a wall of a house by adhesion to make up the wall, and a double-sided tape is provided on at least four sides of the back of the decorative material. The adhesive is applied to the back surface of the decorative material, and the decorative material is adhered and fixed to the non-decorative surface of the wall of the house.

  In a preferred aspect of the present invention, the decorative material comprises a base material made of a calcium silicate plate containing diatomaceous earth and a surface decorative layer formed on the surface of the decorative material.

  In a preferred embodiment of the present invention, the thickness of the double-sided tape is 0.25 mm or less.

  The present invention is a method for applying a decorative material that is attached to a decorative surface of a wall of a house by adhesion to make up the wall, and a double-sided tape is previously applied to at least four sides of the back surface of the decorative material. An adhesive is applied to the back surface of the wall, and then is applied to the decorated surface of the wall.

  ADVANTAGE OF THE INVENTION According to this invention, the shift | offset | difference and floating of the makeup | decoration material at the time of construction can be prevented, and malfunctions, such as peeling of a makeup | decoration material, can be prevented also after construction.

  Below, the construction method of the decorative material in this invention is demonstrated according to drawing. FIG. 1 is a plan view showing an application position of a double-sided tape and an adhesive on the back side of a decorative board in a method for applying a decorative material according to the present invention, and FIG. 2 is an application of a double-sided tape and an adhesive in the method for applying a decorative material according to the present invention. It is sectional drawing which shows a position.

The double-sided tape 1 is affixed around the back surface of the decorative material 3 with no gaps, and a plurality of double-sided tapes 1 are affixed parallel to the long side of the decorative material. By rotating the double-sided tape around all four corners without any gaps, it is possible to prevent floating and peeling from the end during construction. Especially in the case of cosmetics with surface coating, the cosmetic material itself tends to warp concavely, so if it is fixed only with an adhesive, the cosmetic material warps before the adhesive hardens, and the warp has occurred. In some cases, the decorative material may be fixed. However, if 4 rounds are fixed with double-sided tape, the double-sided tape will serve as a temporary stop until the adhesive is cured, and make sure that the cosmetic material will not be warped (the edge of the cosmetic material will not float). Can be fixed. Moreover, when it fixes only with a double-sided tape, generation | occurrence | production of curvature can be prevented, but a decorative material may peel from a wall after construction of a decorative material from the low adhesive force of a double-sided tape. In the case of a construction structure in which a double-sided tape is attached to four circumferences and fixed with both an adhesive and a double-sided tape, it is possible to reliably prevent warping (lifting of the end portion) and peeling.
Such. .

Although it does not specifically limit as a double-sided tape used here, For example, what apply | coated the acrylic adhesive to the polyethylene-lamic cloth base material is used suitably. The thickness of the double-sided tape is preferably 0.1 to 0.5 mm. By setting the tape thickness to 0.1 to 0.5 mm, the distance between the decorative material and the wall surface can be reduced, and damage to the decorative material when attaching accessories such as handrails from above the decorative material is prevented. can do.

Further, an adhesive 2 is applied between the double-sided tapes. By using a double-sided tape and an adhesive in combination, it is possible to more effectively prevent the decorative material from being lifted or peeled off.

As the adhesive used here, a vinyl copolymer resin adhesive, a vinyl acetate resin adhesive, a modified silicon adhesive, or the like is preferably used.

Further, the decorative material 3 includes a base material 4 and a decorative layer 5 as shown in FIG. As the base material, for example, a gypsum board, a slate plate, a calcium silicate plate and the like are preferably used. In particular, a calcium silicate plate containing diatomaceous earth is suitably used as a base material for an interior decorative board because it has a humidity control function and is lightweight. As the decorative layer, for example, an acrylic resin paint or a silicon resin paint is preferably used. In addition, a photocatalyst can be applied to the surface of the decorative layer.

EXAMPLES The present invention will be described in more detail with reference to examples below, but the present invention is not limited to these examples.

(Embodiment) The decorative plate used was a calcium silicate plate whose main component was diatomaceous earth having a width of 910 mm, a height of 1820 mm, and a thickness of 6 mm. As the double-sided tape for construction, a double-sided tape having a width of 25 mm and a thickness of 0.25 mm with a PE laminate cloth was used, and a vinyl copolymer resin adhesive was used as the adhesive. As shown in FIG. 1, a double-sided tape was affixed on the four sides of the back of the decorative material, and a double-sided tape was affixed parallel to the long side of the decorative plate at a pitch of 150 mm. Next, a decorative material was applied to the wooden wall surface in a state where three adhesives each having a bead diameter of 5 mm were applied between the double-sided tapes. After 16 hours of construction, the decorative material was securely attached to the wall surface.

(Comparative Example) A decorative board, double-sided tape, and adhesive similar to those used in the examples were used. As shown in FIG. 3, with a double-sided tape affixed to the back of the decorative plate at a pitch of 200 mm, and with a bead diameter of 5 mm applied between the four sides of the back of the decorative material and the double-sided tape, the decorative material is applied to the wooden wall. It was constructed. After 16 hours of construction, it was confirmed that the edge of the decorative material was floating from the wall surface.

It is a top view which shows the application position of the double-sided tape and the adhesive agent of the back of a decorative board in the construction method of the decorative material which concerns on this invention. It is sectional drawing which shows the application position of the double-sided tape and adhesive agent in the construction method of the cosmetics which concerns on this invention. It is a top view which shows the application position of the double-sided tape on the back of a decorative board and the adhesive agent in the construction method of the conventional decorative material.
