  However, in the invention described in Patent Document 2, it is difficult to make the butted portions of adjacent building boards inconspicuous.

  This invention is made | formed in view of said point, and it aims at providing the building board which can make the butt | matching part of an adjacent building board inconspicuous.

Building board according to the present invention, there is provided a building board having a concave groove which is continuous in the longitudinal direction of the substrate to the end portion of at least one of the lateral direction of the substrate, the groove is the groove width of that is in the longitudinal direction The corners of the boundary part , which are formed to be partially enlarged and contracted and have different groove widths in the front view, form a substantially right angle, and each of the plurality of fine lines that are substantially continuous in the longitudinal direction of the groove has a full length. The plurality of fine lines are non-uniform in color and at least one of them is a dark and dark color .

  In the present invention, it is preferable that a plurality of the concave grooves are formed.

  In the present invention, it is preferable that the fine wire is formed on the entire substrate.

In the present invention, it is preferable that a plurality of the thin wires are formed in a concave groove provided at one short side end of the substrate.

The present invention is formed the groove width of the groove its is scaled by a part of the length, since the groove width of the concave groove in front view the corners of the different boundary portion is a substantially right angle, concave The position of the longitudinal edge of the groove becomes unclear, and the thin wire that is substantially continuous in the longitudinal direction of the concave groove is formed with a substantially constant width over the entire length, so that the construction plate adjacent to the longitudinal direction of the fine wire is abutted The portion is formed substantially in parallel, and the butted portion is difficult to distinguish from the end portion and the thin line in the short direction of the concave groove and can be made inconspicuous.

It is the front view which expanded a part which shows an example of embodiment of this invention. (A) is a front view, and (b) is a sectional view. It is a photograph showing a part of the above. It is a front view which shows an example of other embodiment of this invention.

  Hereinafter, modes for carrying out the present invention will be described.

  As shown in FIG. 2, the building board A of the present embodiment is formed on the surface of the substrate 1 with a long groove 2 in a direction substantially parallel to the longitudinal direction of the substrate 1. If the board | substrate 1 is conventionally used as a building material, it can be used without limitation. Examples of the substrate 1 include a ceramic substrate formed of a hardened cement material, a wood substrate such as plywood, and a metal substrate such as a stainless steel plate. The substrate 1 is formed in a substantially rectangular shape when viewed from the front.

  The recessed groove 2 is recessed on the surface of the substrate 1. The concave groove 2 is formed over substantially the entire length substantially parallel to the longitudinal direction of the substrate 1. A plurality of the concave grooves 2 can be provided so as to be arranged in a direction orthogonal to the longitudinal direction of the substrate 1. In this case, the groove 2 can be provided along at least one longitudinal end 1 a of the substrate 1. Further, a ridge 3 is formed between adjacent grooves 2 and 2. Therefore, a concavo-convex pattern in which the grooves 2 and the ridges 3 are alternately arranged in the direction orthogonal to the longitudinal direction of the substrate 1 is formed on the surface of the substrate 1. In addition, the width dimension (dimension of the direction orthogonal to a longitudinal direction) of the ditch | groove 2 is 3-50 mm, the depth dimension of the ditch | groove 2 is 2-15 mm, and the space | interval of the adjacent ditch | groove 2, 2 shall be 5-50 mm. However, the present invention is not limited to this.

  The dimension of the groove width of the concave groove 2 is not constant over the entire length in the longitudinal direction, and is partially expanded or reduced. In this case, in each concave groove 2, a narrow width portion 2a having the narrowest groove width, a wide width portion 2b having the widest groove width, and an intermediate groove formed in a groove width between the narrow width portion 2a and the wide width portion 2b. It can be formed so as to be mixed with the width portion 2c. Formed so that the groove width of the intermediate groove width portion 2c is 1.01 to 1.2 times and the groove width of the wide portion 2b is 1.05 to 1.5 times the groove width 1 of the narrow portion 2a. It is preferable to do this. The ratio of the narrow part 2a, the wide part 2b, and the intermediate groove width part 2c per one of the concave grooves 2 is not particularly limited and can be set arbitrarily. In addition, in the present Example, although the building board from which groove width was changed in three steps was shown, it should just be two steps or more without being limited to this. The concavo-convex pattern is a concavo-convex pattern formed in a so-called border-like concavo-convex pattern in which the ridges 3 are continuous over the entire length in the longitudinal direction of the substrate 1, but the groove width of the concave groove 2 as shown in FIG. By forming the groove portion 6 substantially parallel to the short direction of the ridge 3 at the boundary where the ridges 3 are different, a plurality of block-like ridges 3 separated by the groove 2 and the groove portion 6 are formed in a concavo-convex pattern. It may be done.

  The concavo-convex pattern of the substrate 1 is formed, and fine wires 4 are formed on the surface. The thin wire 4 is formed so as to be substantially continuous in the longitudinal direction of the concave groove 2. Therefore, the thin line 4 may be a straight line or a broken line. The fine wire 4 can be provided on the bottom surface of the groove 2. When the side surface of the concave groove 2 is formed with a slope, it is preferable to form the thin wire 4 on the slope. Although the fine wire 4 can be formed in the concave groove 2 formed along at least one longitudinal end portion 1 a of the substrate 1, the fine wire 4 may be formed in the other concave groove 2. Further, a plurality of fine wires 4 may be formed for one concave groove 2. In this case, it is preferable to form a plurality of fine wires 4 in the concave groove 2 formed along at least one longitudinal end 1a of the substrate 1. The thin wire 4 can also be formed on the surface of the ridge 3. Therefore, a plurality of thin wires 4 can be provided over the entire surface of the substrate 1. Thereby, it becomes difficult to distinguish the butting part T and the fine wire 4 of the adjacent building boards A and A.

  Forms such as the thickness of the thin line 4, the interval between the adjacent thin lines 4, 4, the color of the thin line 4, and the continuity of the thin line 4 (straight line or broken line) can be arbitrarily set. The thickness (width dimension) of the thin wire | line 4 can be set to 0.1-5 mm, for example, Preferably it is 0.3-3 mm. The space | interval of the adjacent thin wires 4 and 4 can be set to 0-20 mm, for example, Preferably it is 0.2-5 mm. As the color of the thin line 4, it is preferable to select a dark and dark color such as black-gray for at least one in order to make it difficult to distinguish the butted portion T and the thin line 4. Moreover, when forming the thin wire | line 4 with a broken line, the space | interval of a dot can be set to 0.1-5 mm, for example, Preferably it is 0.3-1 mm.

  A wide variety of forms can be employed for the plurality of thin wires 4 formed on one building board A. That is, the thickness and color can be made different for each thin line 4, and the interval between adjacent thin lines 4 and 4 can be partially widened or narrowed. As described above, at least one of the thickness of the fine wire 4, the interval between the adjacent fine wires 4 and 4, and the color of the fine wire 4 is formed unevenly, so that the abutting portions of the adjacent building boards A and A are It can be made less noticeable. However, the thickness of each thin wire 4 is formed with a substantially constant width over the entire length in the longitudinal direction. Thereby, the butting | matching part of adjacent building board A and A can be made not to be more conspicuous.

  Further, it is preferable that the fine line 4 is formed by printing with an ink jet printer so that the form of the fine line 4 can be easily created or changed. In this case, color change, pattern change, etc. can be easily performed as compared with printing using a printing plate such as a relief plate or an intaglio. When the fine line 4 is printed by an ink jet printer, data in the form of the fine line 4 can be input to a control means such as a computer, and the fine line 4 can be printed by controlling the ink jet printer by the control means based on this data.

  And as shown in FIG. 1, said building board A and the other building board A are arrange | positioned so that the longitudinal end part 1a of the board | substrate 1 and the longitudinal end part 1b of the other board | substrate 1 may adjoin, and it adjoins. When the longitudinal ends 1a and 1b are butted together, the boundary (joint) of the building boards A and A formed by the butting and the longitudinal edge of the bottom of the groove 2 (adjacent grooves 2 and ridges 3) 5) and the thin line 4 are difficult to distinguish. Therefore, the abutting portion T of the adjacent building boards A and A becomes less conspicuous due to the long end edge 5 of the groove 2 and the thin wire 4, and the appearance of the building formed by arranging a plurality of building boards A side by side. It can be made difficult to damage. In addition, in the present Example, although the butt | matching part T of the building boards A and A located up and down has been demonstrated, it is not limited to this, For example, the real part formed in an upper-lower-end surface or a left-right end surface This also has the same effect in the joint portion (butting portion) that is phase-matched by the above.

  In FIG. 3, an example of the butting | matching part of adjacent building board A and A is shown with a photograph. Thus, it turns out that the butting | matching part of adjacent building board A and A cannot be visually recognized clearly. In addition, as for the building board A of FIG. 3, the design of the surface is formed in the wood cutting tone by inkjet printing. In other words, the split wood tone is an image of piled up trees that take advantage of the natural cracking, texture, and handmade atmosphere created by rough splitting with raw or chisel. The result is a more natural texture by overlapping the modeling taken from the wood and the printed pattern utilizing the subtle atmosphere and color of the wood.
