[Industrial applications]

 The present invention relates to a building board used for a ceiling, a wall, etc. of a building, and relates to a three-dimensional shaped building board composed of a combination of a flat plate portion and a convex portion.

[0002]

[Prior Art]

 Conventionally, for a building board (21) used for a ceiling or wall of a building, for example, as shown in FIGS. 12 to 14, various flat shapes (22) are combined with various convex shapes (23) to obtain a design effect. Many things are made. However, in such a conventional building board (21), when the rising portion (a) of the convex portion (23) from the flat plate portion (22) is formed in a vertical or tapered shape, when viewed from a distance. The boundary line between the flat plate portion (22) and the convex portion (23) is not conspicuous, and the three-dimensional effect is poor, and the design effect cannot be expected so much. Especially when it is used on the ceiling, the tendency is remarkable when the light rays do not hit directly. In addition, when the convex portion (33) is adhered as shown in FIG. 15 to manufacture a three-dimensional ceiling or the like, a flat plate (32) having an uneven pattern such as embossing may be used in order to improve the design. However, at that time, uneven gaps (34) are formed in the bonded portion, which is unsightly.

[0003]

[Problems to be solved by the device]

 Therefore, the problem to be solved by the present invention is to provide a three-dimensional structure building board in which the boundary between the flat plate portion and the convex portion is emphasized and the three-dimensional and design feeling is excellent.

[0004]

[Means for Solving the Problems]

 Thus, according to the present invention, "a building board which is used for a ceiling, a wall, etc. of a building, and which comprises a flat plate portion (2) and a convex portion (3) projecting on the flat surface, There is provided a three-dimensional structure building board (1) "in which a concave groove (G) capable of producing a shadow is formed in a boundary line (b) between the (2) and the convex part (3).

The three-dimensional structure building board (1) of the present invention is a separate body even if it is constructed by cutting from one piece as long as it has a flat plate section (2) and a convex section (3). It may be configured by combining.

In the three-dimensional structure building board (1) of the present invention, a groove (G) is formed at a boundary line (b) between the flat plate portion (2) and the convex portion (3). The concave groove (G) may have any shape as long as it can shade the boundary line (b) between the flat plate portion (2) and the convex portion (3). As an example, a slit groove (S) or a reverse taper (T) is formed so that the rising from the flat plate portion (2) to the convex portion (3) forms an acute angle. Examples of the former slit groove (S) include those shown in FIGS. 6 to 8, and examples of the latter concave groove (G) by the reverse taper (T) include those shown in FIGS. , But not limited to these.

When the concave groove (G) is provided as the slit groove (S), the depth (a) and the width (b) of the slit can be shaded at the boundary line (b) regardless of whether the depth (a) or the width (b) of the slit is large. It is selected within the range that does not affect the strength. Taking FIG. 6 as an example, the depth (L) of the convex portion (3) in the width direction and the height (H) from the flat plate portion (2) to the apex of the convex portion (3) are different from the depth. (a) may be 1 to L / 3 mm, preferably 2 to 5 mm, and width (b) may be 1 to H / 2, preferably 2 to 3 mm, but is not limited thereto. Further, the cutting direction for forming the slit groove (S) may be any direction as long as it can produce a shadow in the boundary line portion (b). On the other hand, in the case of the inverse taper (T), when the rising portion of the convex portion (3) is a curved surface, its tangent line is set to make an acute angle with the plane on the flat plate portion (2). Taking Fig. 11 as an example, the depth of penetration (d) of the reverse taper (T) is 1 to L / 3 with respect to the length (L) of the convex portion (3) in the width direction. It is preferably 2 to 5 mm, but not limited to this.

[0008]

[Action]

 According to the present invention, since the groove (G) formed in the boundary line (b) between the flat plate part (2) and the convex part (3) is shaded, the flat plate part (2) is not shaded. The protruding state of the convex portion (3) becomes clear, and the feeling of standing is emphasized.

[0009]

【Example】

 Hereinafter, the present invention will be described in detail according to illustrated embodiments, but the present invention is not limited thereto. Example 1 As shown in FIG. 1, a rock wool board having a specific gravity of 0.4 and a thickness (A) of 19 mm was cut using an NC router, and a flat plate portion (2) having a thickness (B) of 9 mm and a radius (R) of 8 mm were used. An integral structure having a semi-circular cross section and a stripe-shaped convex portion (3) was prepared, and a vinyl acetate-based emulsion paint was applied to this to obtain a three-dimensional structure building board (1) of the present invention. In the above-mentioned three-dimensional structure building board (1), when the above-mentioned cutting, the convex portion (3) rises from the flat plate portion (2) to the so-called boundary portion (b), and the depth (d) is 2 mm reverse taper ( T) is formed.

As a construction example of the three-dimensional structure building board (1) manufactured as described above, for example, as shown in FIG. 2, a plasterboard (4) is discarded and attached to a ceiling edge to form a base. After that, the above three-dimensional structure building board (1) is used together with, for example, a vinyl acetate emulsion adhesive (5), and is fixed to the plaster board (4) base from the surface with staples (6).

In the above-mentioned three-dimensional modeling building board (1), a concave groove (G) formed by a reverse taper (T) is formed at the boundary line (b) between the convex part (3) and the flat plate part (2). As a result, shading is added, the boundary (b) is emphasized, the protruding state of the convex part (3) becomes clear, and the three-dimensional effect is full.

Example 2 A rockwool board having a specific gravity of 0.4 and a thickness (A) of 19 mm similar to that of Example 1 is shown in FIGS. 3 (planar schematic view) and 4 (cross-sectional schematic view) using an NC router. An annular member (13) having such a design was produced. The dimensions of the notch (14) formed around the bottom of the annular member (13) are 3 mm in depth (a) and 3 mm in width (b). On the other hand, a rock wool board having a specific gravity of 0.4 and a thickness (B) of 9 mm was used, and hot-press embossing was performed on the surface of the rock wool board with a die having an uneven pattern attached thereto to produce a flat plate member (12). On the embossed surface of the flat plate member (12), the annular member (13) having the above-mentioned design was attached using, for example, a vinyl acetate emulsion adhesive to obtain a three-dimensional structure building board (11) shown in FIG. The three-dimensional structure building board (11) produced above has an annular slit groove (S) at the boundary line (b) between the flat plate member (12) and the annular member (13). The resulting outline of the annular member (13) protruding from the flat plate member (12) is clearly projected on the flat plate member (12), giving a three-dimensional effect. It has become a thing. Also, the boundary line (b) between the embossed surface of the flat plate member (12) and the annular member (13) is clearly shaded by the annular slit groove (S), and there is no unevenness due to the embossed surface. Since the adhesive layer gap cannot be seen outside, the boundary line (b) between the flat plate member (12) and the annular member (13) is neatly formed. Due to the above, a remarkable design effect is achieved.

[0013]

[Effect of the device]

 According to the present invention, a material having the same thickness can be expressed in a three-dimensional manner with richer shadows than conventional products. Therefore, the thickness can be reduced, and the weight and cost can be reduced. When a combination of a convex portion and a flat plate portion is used, since a concave groove is formed in these adhesive layer portions, the adhesive layer portion can be made unnoticeable and the boundary line portion can be formed regardless of the flatness of the flat plate portion. Can be finished neatly. From the above, a remarkable design effect can be achieved.
