Description

  The present invention relates to a decorative material and a wall surface construction method using the decorative material.

  Conventionally, when connecting makeup materials to the wall surface, it is known to use a watermark to construct the makeup of adjacent makeup with a gap, construction by a joiner, butting, agitation, etc. It is requested not to stand out originally.

  However, it is an ideal construction method because the joints are not conspicuous and there is no sense of incongruity even in the construction described above, but when the dimensional shrinkage due to the temperature and humidity of the cosmetic material is large or when it is stretched On the other hand, gaps and swells may occur in the joints, making it difficult to see. In addition, when the base material is inorganic, it is brittle and may be damaged when hit by an object.

The present invention has been studied in view of such circumstances, and is a cosmetic material characterized in that the following is taken into consideration so that gaps in joint portions due to dimensional shrinkage of the cosmetic material are not noticeable.
That is, the invention described in claim 1 is the decorative material 1 in which the inclined surface 5a is formed on one side surface along the longitudinal direction and the reverse inclined surface 5b is formed on the other side surface.
Further, the claimed invention, together with the inclined surface 6a is formed on one side accompany the longitudinal direction, the inclination angle alpha ₁ of the opposite inclined face 6b with opposite inclined face 6b is formed on the other side surface inclined a decorative material 1 ', characterized in that is smaller than the inclination angle alpha ₂ of the surface 6a.
The invention described in claim 3 is a wall surface construction method characterized in that, when a wall surface is constructed using a plurality of the decorative materials according to claim 1, the slope surface and the reversely inclined surface are overlapped. It is.
Further, in the invention according to claim 4, when the wall surface is constructed using a plurality of the decorative materials according to claim 2, the inclined surface and the reverse inclined surface are partially in contact with each other so as to open from the contact portion toward the wall surface. A method for constructing a wall, characterized in that it is connected to the wall. A decorative material 1 is characterized in that a decorative layer 2 is formed on a base material 3, an inclined surface 5a is formed on one side surface along the longitudinal direction, and a reverse inclined surface 5b is formed on the other side surface. .

  According to the present invention, when the decorative material is continuously provided on the wall surface, the inclined surface and the reverse inclined surface are formed on the side surface of the decorative material, the inclined surface and the reverse inclined surface are overlapped, and a part is contacted. By constructing, it becomes inconspicuous even if a gap due to dimensional change occurs. Moreover, no joiner is required, and no skill in wall construction work is required.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a structural cross-sectional view showing a decorative material 1 of Example 1. FIG.
In FIG. 1, a decorative material 1 is composed of a decorative layer 2 and a base material 3. The decorative material 1 has a thickness of 6 mm, and one side surface of the decorative material 1 is formed with a 45 ° inclined surface 5a and the other side surface. Similarly, a reverse inclined surface 5b having the same angle is formed, and an inclined surface 6 of −45 ° is formed in the upper part.

  FIG. 2 is a structural cross-sectional view showing the decorative material 1 of Example 2. Like the Example 1, the decorative material 1 is composed of a decorative layer 2 and a base material 3, and one side surface of the decorative material is inclined by 45 °. A surface 5a is formed, a reverse inclined surface 5b having the same angle is formed on the other side surface, and a curved surface 7 is formed on the upper portion. Providing the curved surface 7 at the top makes it difficult to recognize gaps due to dimensional changes, and forming the curved surface makes it difficult to be scratched without corners and is an important constituent requirement.

  In Examples 1 and 2, an inorganic base material, specifically, a volcanic glassy multilayer board is used for the base material 3 of the decorative material 1 for the purpose of flame retardancy. A plate may be used. Moreover, when flame retardance is not required, woody base materials, such as MDF, a plywood, and a particle board, may be sufficient.

In the present invention, a method using an unsaturated polyester resin coating is used as a decorative layer. In this method, a decorative paper is bonded to a base material, a resin liquid is applied to the decorative paper surface, and then the coated surface is coated with a plastic film. In this method, the film is spread with a roller and the plastic film is peeled off after the resin is cured.
Another method for applying the decorative layer may be a method using coated paper or resin-impregnated decorative paper. Coated paper has an acrylic urethane, polyester urethane, polyurethane, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer on one side of printing base paper with basis weight of 20-60 g / m ² The surface is protected by such as.
The method using resin-impregnated decorative paper is a method in which a base paper for decorative board is impregnated with a resin liquid containing a thermosetting resin as a main component, and the dried resin-impregnated decorative paper is laminated with a base material, followed by hot pressing. . As a means for applying the decorative layer, a generally known method may be used.

  3 and 4 are cross-sectional views showing the structure when the decorative materials of Examples 1 and 2 are continuously provided, and the inclined surface and the reverse inclined surface overlap each other. In the present invention, the angle of the inclined surface is 45 °. However, if the angle is approximately 20 to 70 °, the dimensional change can be visually absorbed. If the angle is less than 20 °, the side surface becomes acute and breaks when it hits an object. It becomes easy, and when it exceeds 70 °, it becomes close to butt construction, and it becomes conspicuous when a gap occurs. This is also an important component requirement.

FIG. 5 is a cross-sectional view of the decorative material of Example 3, and FIG. 6 is a cross-sectional view showing the structure when the decorative material of Example 3 is continuously provided. The angle α ₂ of the inclined surface and the reverse inclined surface α ₁ The angle is different. In the case where the inclined surface and the reverse inclined surface are at the same angle as in the first and second embodiments, there is a case where a slip occurs at the abutting portion at the time of bonding during construction, and it takes time to work. If it demonstrates in FIG. 2, the reverse inclined surface of 5b will slip | deviate to an upward diagonal direction easily slipping on the inclined surface of 5a. For this reason, as shown in Example 3 of FIGS. 5 and 6, it is desirable to make the inclination angle of the reverse inclined surface smaller than the inclined surface to be an acute angle (α ₁ <α ₂ ).

  Furthermore, in the present invention, the side surfaces of the decorative material are color-matched by applying the same color coating as the decorative layer so that there is no sense of incongruity of the joints, and there is no sense of incongruity in the design, and the influence of the dimensional change is visually recognized. This is also an important component of the present invention.

  In the embodiment of the present invention, the decorative material 1, 1 'is composed of the base material 3 and the decorative layer 2. However, if the same inclined surface and the reverse inclined surface are formed on the side surface, the solid material It may be a product coated with a thermoplastic resin, an extruded product of a thermoplastic resin, etc., and the material of the decorative material is not particularly limited.
