1. Overview As shown in FIG. 1, a building board 1 according to the present embodiment includes a plurality of ridges 3 and a plurality of grooves 4 on its surface (front). The plurality of ridges 3 are arranged parallel to each other and extend in one direction (horizontal direction). Each of the plurality of grooves 4 exists between adjacent ridges 3 among the plurality of ridges 3 .

One of the features of the building board 1 according to this embodiment is that at least one or more protrusions 5 are present in at least one or more grooves 4 among the plurality of grooves 4 (FIG. 2). reference).

As shown in FIG. 6, when two building boards 1 are superimposed with their front faces facing each other, the protrusions 5 are formed so that the grooves 4a of one building board 1a are aligned with the protrusions 3b of the other building board 1b. prevent getting stuck.

Therefore, according to the building board 1 according to the present embodiment, when two building boards 1 are superimposed with their front faces facing each other, the groove 4a of one building board 1a and the protrusion 3b of the other building board 1b are aligned. can be made difficult to get stuck.

2. Details Hereinafter, the building board 1 according to the present embodiment will be described with reference to the drawings. Each drawing is a schematic drawing, and the size of each component in the drawing does not necessarily reflect the actual size. In the figure, arrows defining "up", "down", "left", "right", "front" and "back" are shown, but these arrows are shown for convenience of explanation. It is not intended to limit the direction of the building board 1, and does not involve any substance. Further, hereinafter, "front" means a surface of an object facing forward, and "front view" means looking at the front of the object.

As shown in FIG. 1, the building board 1 according to this embodiment has a horizontally long rectangular plate shape extending in the vertical direction and the horizontal direction. The building board 1 includes a plurality of (four in this embodiment) ridge groups 2 and a pseudo joint 7 . The material and application of the building board 1 are not particularly limited. Examples of the building board 1 include a ceramic siding, a metal siding, a fiber cement board, a building board containing an organic material (resin siding, etc.), and the like. When the building board 1 is used for the outer wall of a building, a plurality of building boards 1 are arranged adjacent to each other vertically and horizontally. The building board 1 may be stretched horizontally or vertically.

<Group of ridges>
A plurality of protrusion groups 2 are present in front of the building board 1 . The plurality of ridge groups 2 are arranged in one direction (the left-right direction in this embodiment). Each of the plurality of ridge groups 2 has a rectangular shape in a front view (in this embodiment, a substantially square shape in a front view). Each of the plurality of protrusion groups 2 has a pattern. The pattern of the group of protrusions 2 may be the same or different. A building board 1 according to this embodiment includes three types of protrusion groups 2a, 2b, and 2c with different patterns (see FIG. 1).

Each of the plurality of ridge groups 2 has a plurality of ridges 3 and a plurality of grooves 4 (see FIGS. 1 and 2). Furthermore, at least one of the plurality of projected streak groups 2 (all projected streak groups 2 in this embodiment) has at least one or more decorative joints 6 .

≪Protrusion≫
The ridges 3 can be elements forming the pattern of the ridge group 2 . The ridge 3 has a stripe shape that protrudes forward and extends in one direction (horizontal direction in this embodiment). The cross-sectional shape of the protrusion 3 is not particularly limited, but includes, for example, a trapezoidal shape (see FIG. 3A) and a triangular shape (see FIG. 3B). When stacking two building boards 1 with their front faces facing each other, the ridges 3 of one building board 1 have a cross-sectional shape that can be fitted into the grooves 4 of the other building board 1. there is Also, if the recessed groove 4 of the other building board 1 does not have the projection 5, the tip of the protrusion 3 of the building board 1 may contact the bottom surface of the recessed groove 4 (in contact with the butted state). It is possible. The plurality of ridges 3 are arranged parallel to each other in a direction perpendicular to one direction (vertical direction in this embodiment). In addition, the protrusion 3 may have a missing portion 31 (see FIGS. 3A and 3B). The size, shape, number, and position of the missing portion 31 are not particularly limited. The missing portion 31 can also be an element forming the pattern of the group of protrusions 2 .

In this embodiment, the shape of at least one of the plurality of ridges 3 is partially different in one direction. In other words, not all ridges 3 have the same shape in one direction. Therefore, it is possible to make it difficult to give a monotonous impression to the viewer of the building board 1 .

The method for changing the shape of the ridges 3 is not particularly limited. methods (see FIGS. 4A and 4B), and the like.

First, a method for changing the projection height H of the ridge 3 will be described. In this method, at least one of the ridges 3 has an elevation portion 81 and a non-elevation portion 82 (see FIGS. 1 and 2). The elevation portion 81 is higher and/or lower than the non-elevation portion 82 . The elevation portion 81 may include only a high portion, may include only a low portion, or may include both a high portion and a low portion.

That is, as shown in FIGS. 3A and 3B, the protrusion height H of at least one of the protrusions 3 is partially different in one direction (in the left-right direction in this embodiment). Here, the protrusion height H of the protrusion 3 means the length of the protrusion portion of the protrusion 3 in the front-rear direction. 3A and 3B, H(H) is the projection height of the high portion of the elevation portion 81, H(L) is the projection height of the low portion of the elevation portion 81, and H(L) is the projection height of the non-elevation portion 82. 0). In such a case, for example, if there is a light source such as the sun in the upper front, a shadow corresponding to the protrusion height H of the protrusion 3 is formed in the concave groove 4 immediately below the protrusion 3 . This makes it possible to make the shadows partially different.

In addition, the protrusion height H of the elevation portion 81 may be changed continuously or may be changed discontinuously. Moreover, the protrusion height H of the boundary portion between the elevation portion 81 and the non-elevation portion 82 may change continuously or may change discontinuously.

Next, a method for changing the extension of the ridges 3 will be described. In this method, at least one of the ridges 3 has a meandering portion 91 and a non-serpentine portion 92 (see FIGS. 1 and 2). The meandering portion 91 is a portion that meanders and extends in one direction. The meandering period and amplitude are not particularly limited. The non-serpentine portion 92 is a portion extending linearly in one direction.

That is, as shown in FIGS. 4A and 4B, at least one of the ridges 3 is partially meandering in one direction (horizontal direction in this embodiment). As described above, in this embodiment, at least one of the ridges 3 extends in the horizontal direction while fluctuating in the vertical direction. can be seen directly. Furthermore, a meandering shadow is likely to be formed in the groove 4 directly below the meandering portion 91 , and a linear shadow is likely to be formed in the groove 4 directly below the non-serpentine portion 92 .

The meandering portion 91 may be the elevation portion 81 or the non-elevation portion 82 . Similarly, the non-serpentine portion 92 may be the elevation portion 81 or the non-elevation portion 82 . This makes it possible to change the width of a meandering shadow or change the width of a linear shadow. Note that the width means the length in the vertical direction unless otherwise specified.

≪Groove≫
The recessed groove 4 can also be an element forming the pattern of the group of ridges 2 in the same manner as the ridge 3 . The recessed groove 4 is recessed rearward and has a stripe shape extending in one direction (left-right direction in this embodiment).

Each of the plurality of grooves 4 exists between adjacent ridges 3 among the plurality of ridges 3 . The width of the groove 4 may be the same as or different from the width of the protrusion 3 .

Each groove 4 is likely to have a shadow according to the projection height H and the extension of the protrusion 3 directly above each groove 4 . For example, if the projection height H of the ridge 3 is different, the width of the shadow will be widened or narrowed. Also, if the extension of the ridges 3 is different, the shadow extends meanderingly or linearly.

Furthermore, in the present embodiment, at least one or more (plurality of) grooves 4 among the plurality of grooves 4 have at least one or more protrusions 5 . The protrusions 5 have the function of suppressing the engagement of the projections 3b of one building board 1b with the grooves 4a of the other building board 1b when the front surfaces of the two building boards 1 are placed facing each other. (see FIG. 6). That is, when two building boards 1a and 1b are superimposed with their front faces facing each other, the projections 5a present in the grooves 4a of one building board 1a interfere with the ridges 3b of the other building board 1b. Similarly, the protrusion 5b present in the groove 4b of the other building board 1b also interferes with the ridge 3a of the other building board 1a.

The projection 5 protrudes forward. The protrusion height h of the protrusion 5 is the same as or lower than the protrusion height H of the protrusion 3 (see FIG. 6).

≪Decorative joint≫
The decorative joint 6 is a pseudo joint that can be visually recognized as a joint. The decorative joint 6 can also be an element forming the pattern of the group of ridges 2 in the same manner as the ridges 3 and the grooves 4 . The decorative joint 6 is a joint extending in a direction orthogonal to one direction (vertical direction in this embodiment) while recessing backward. The length of the decorative joint 6 in the vertical direction is shorter than the length of the building board 1 in the vertical direction. The width (the length in the left-right direction) of the decorative joint 6 is not particularly limited. A width equivalent to the sealing width is preferable.

The decorative joint 6 may be formed intermittently or may be formed continuously. Hereinafter, the case where the decorative joint 6 is intermittently formed and the case where the decorative joint 6 is formed continuously will be described separately.

First, the case where the decorative joint 6 is intermittently formed will be described. In this case, one decorative joint 6 has a plurality of continuous portions 61 (see FIGS. 1 and 2). A continuous portion 61 is a continuous portion. The plurality of continuous portions 61 are present on the same straight line extending in the vertical direction (see straight lines L1 and L2 in FIG. 2). A discontinuous portion 62 (portion surrounded by a broken line in FIG. 2) exists between the vertically adjacent continuous portions 61 among the plurality of continuous portions 61 . The discontinuous portion 62 is a portion where the continuous portion 61 does not exist, and the discontinuous portion 62 is provided with the ridge 3 and the groove 4 . Due to the presence of the discontinuous portion 62, the decorative joint 6 is intermittently formed.

When one decorative joint 6 has a plurality of continuous portions 61, the vertical lengths of the continuous portions 61 may be the same or different. The vertical length of the discontinuous portion 62 (the distance between the vertically adjacent continuous portions 61 ) may be the same as or different from the vertical length of the continuous portion 61 .

Next, the case where the decorative joint 6 is formed continuously will be described. In this case, one decorative joint 6 has a single continuous portion 61 (not shown). However, since the decorative joint 6 (that is, one continuous portion 61) in this case is shorter than the vertical length of the building board 1, the upper and lower ends of the building board 1 are not connected.

In the present embodiment, each of the plurality (four) of ridge groups 2 has at least one or more (two) decorative joints 6 . Furthermore, in this embodiment, at least one or more (two) decorative joints 6 are intermittently formed.

FIG. 2 illustrates a case where one ridge group 2 has two decorative joints 6 (a decorative joint 6 on a straight line L1 and a decorative joint 6 on a straight line L2) in the left-right direction. One ridge group 2 may have three or more decorative joints 6 in the left-right direction. In this case, the spacing W1 between the decorative joints 6 adjacent in the left-right direction may be the same or different.

Further, in the present embodiment, when the building board 1 is viewed from one direction (horizontal direction), at least one or more (two) decorative joints 6 are arranged in a direction perpendicular to the one direction of the building board 1 (vertical direction). exists throughout. 2, there are portions where the continuous portion 61 does not exist (for example, the discontinuous portion 62) on the straight line L1. , there exists a continuous portion 61 existing on the straight line L2. In this way, when the building board 1 is viewed from the left and right, it looks as if one decorative joint 6 connects the upper and lower ends of the building board 1 .

In this embodiment, the protrusion 5 is present in the decorative joint 6 . Specifically, the protrusions 5 are present on at least one side (both left and right sides in the present embodiment, but may be only on the left side or only on the right side) in one direction (horizontal direction) of the decorative joint 6 (see FIG. 5). . Therefore, when the building board 1 is viewed from the left-right direction, the projection 5 can be present over the entire vertical direction of the building board 1 . As a result, when two building boards 1 are superimposed with their front surfaces facing each other, even if the two building boards 1 are displaced in the vertical direction, the recessed groove 4a of one building board 1a will fit into the groove 4a of the other building board 1a. It is possible to suppress the protrusion 3b of 1b from being fitted (see FIG. 6).

It is preferable that the positions of the decorative joints 6 in one direction (horizontal direction) of the building board 1 do not coincide when the two building boards 1 are superimposed with their front faces facing each other. As a result, it is possible to prevent the protrusion 5 existing in the decorative joint 6 of one of the building boards 1 from getting into the decorative joint 6 of the other building board 1 . Therefore, for example, the plurality of decorative joints 6 are formed asymmetrically with respect to the center line of the building board 1 in the left-right direction.

<Pseudo joint>
Like the decorative joint 6, the pseudo joint 7 is also a pseudo joint that can be visually recognized as a joint. In this embodiment, the pseudo joint 7 exists between the adjacent ridge groups 2 of the plurality of ridge groups 2 . The pseudo joint 7 is a joint extending parallel to at least one decorative joint 6 . In the present embodiment, the pseudo joint 7 is a joint extending vertically while recessing backward. The vertical length of the pseudo joint 7 is equal to the vertical length of the building board 1 . In other words, the pseudo joint 7 connects the upper and lower ends of the building board 1 . The width (the length in the left-right direction) of the pseudo joint 7 is not particularly limited.

The interval W2 between the false joint 7 and the decorative joint 6 adjacent in the left-right direction may be the same as or different from the interval W1 between the decorative joints 6 adjacent in the left-right direction (see FIG. 2).

As shown in FIG. 7, the portions (intersection portions 71) where the pseudo joint 7 and each of the plurality of ridges 3 intersect are raised. A portion where the pseudo joint 7 and each of the plurality of grooves 4 intersect, that is, a portion (non-intersecting portion 72) where the pseudo joint 7 and each of the plurality of ridges 3 do not intersect is not raised. The non-intersecting portion 72 may be flush with the groove 4 or recessed behind the groove 4 . In this way, in the pseudo joint 7, raised intersection portions 71 and non-raised non-intersection portions 72 are alternately arranged in the vertical direction. As a result, the pseudo joint 7 appears to extend vertically while undulating in the front-rear direction. Therefore, the pseudo joint 7 looks as if it is filled with a sealing material (a hardened irregular-shaped sealing material made of a paste-like filling material).

Furthermore, in the present embodiment, the tip of each of the plurality of ridges 3 facing the pseudo joint 7 has a surface (slanted surface 30 ) that slopes toward the pseudo joint 7 . As a result, shadows at the boundaries between the pseudo joints 7 and the ridges 3 can be made less conspicuous than when the tip of the ridges 3 has a steep surface with respect to the pseudo joints 7 . Furthermore, when the building board 1 is manufactured using a ceramic material, the filling property of the ceramic material into the mold can be improved.

<Effect>
In this embodiment, at least one or more protrusions 5 are present in at least one or more grooves 4 among the plurality of grooves 4 . The projection 5 prevents the protrusion 3b of one building board 1b from fitting into the groove 4a of one building board 1a when the two building boards 1 are superimposed with their front surfaces facing each other (Fig. 6).

Further, in the present embodiment, when the building board 1 is viewed from one direction (horizontal direction), at least one decorative joint 6 extends over the entire direction (vertical direction) orthogonal to the one direction of the building board 1. exist. Furthermore, in this embodiment, the protrusions 5 are present on both sides of the decorative joint 6 in one direction (horizontal direction) (see FIG. 5). Therefore, when the building board 1 is viewed from the left-right direction, the projection 5 can be present over the entire vertical direction of the building board 1 . As a result, when two building boards 1 are superimposed with their front surfaces facing each other, even if the two building boards 1 are displaced in the vertical direction, the recessed groove 4a of one building board 1a will fit into the groove 4a of the other building board 1a. It is possible to suppress the protrusion 3b of 1b from being fitted (see FIG. 6).

Therefore, according to the building board 1 according to the present embodiment, when two building boards 1 are superimposed with their front faces facing each other, the groove 4a of one building board 1a and the protrusion 3b of the other building board 1b are aligned. can be made difficult to get stuck.

3. Others Although the embodiment of the present invention has been described above, the present invention is not limited to this and can be appropriately modified without departing from the technical idea of the present invention.

Although the building board 1 according to this embodiment is horizontally long, the aspect ratio of the building board 1 is not particularly limited.

In this embodiment, the pseudo joint 7 exists between the adjacent ridge groups 2 of the plurality of ridge groups 2, but a boundary line portion 70 may exist instead of the pseudo joint 7 (Fig. 8 reference). As shown in FIG. 8, in the boundary line portion 70, the right end portions of the plurality of protrusions 3L of the left protrusion group 2L and the left end portions of the plurality of protrusions 3R of the right protrusion group 2R They overlap in the vertical direction. In the boundary line portion 70, when viewed from the horizontal direction, the protrusions 3L of the left protrusion group 2L and the protrusions 3R of the right protrusion group 2R are alternately arranged in the vertical direction. In other words, in the boundary line portion 70, when viewed from the left-right direction, the protrusions 3L of the left protrusion group 2L face the grooves 4R of the right protrusion group 2R, and the protrusions of the right protrusion group 2R face each other. The ridge 3R faces the groove 4L of the ridge group 2L on the left side.
