Mode for Carrying Out the Invention
[0017] <Building Material> Hereinafter, the building material 1 according to the present embodiment will be described with reference to the drawings. The following embodiment is merely one of various embodiments of the present invention. The following embodiment can be variously modified according to the design, etc., as long as the object of the present invention can be achieved. Further, each drawing described in the following embodiment is a schematic diagram, and the ratio of the size and thickness of each component in the drawing does not necessarily reflect the actual dimensional ratio. Hereinafter, "front view" means looking at the object from the front.
[0018] (Overview) In order to solve the above-mentioned problems, the inventors have intensively studied and found that in a building material having a horizontal joint and a pattern on the surface, the visibility of each part can be controlled by the light and shade of the horizontal joint, etc., and thus completed the present invention.
[0019] The building material 1 of the present invention has, on its surface, one or more horizontal joint portions 10 extending horizontally in the construction state and a plurality of pattern portions 20. The pattern portions 20 include a plurality of upper pattern portions 21 adjacent upward along the horizontal joint portion 10 and a plurality of lower pattern portions 22 adjacent downward along the horizontal joint portion 10. In the building material 1, a dark-colored portion X is provided partially in the horizontal joint portion 10.
[0020] The "dark-colored portion" refers to a portion in the horizontal joint portion and the pattern portion of the building material where the color is made darker compared to the surrounding horizontal joint portion and pattern portion. Specifically, the dark-colored portion X is a portion where the color of the horizontal joint portion, the pattern portion, etc. of the original building material is further darkened by printing, painting, etc.
[0021] According to the building material 1 of the present invention, it is possible to reduce the conspicuousness of joints, pattern biases, horizontal joint misalignments, etc. Although the reason for achieving the above effects when the building material 1 of the present invention has the above configuration is not necessarily clear, for example, by darkening a part of the horizontal joint portion 10, a conspicuous place is created within the building material, so that even for the conspicuousness caused by the joints becoming darker due to manufacturing or construction errors, the line of sight can be diverted without being caught by the joints. And it is considered that by controlling the shadow effect of the concave portion, it is possible to correspond to building materials with various designs.
[0022] Also, according to the present invention, by providing the dark-colored portion X partially in the horizontal joint portion 10, the unevenness feeling, three-dimensional feeling, etc. of the building material 1 can be enhanced. In this way, by enhancing the unevenness feeling, three-dimensional feeling, etc., the building material 1 can: (1) enhance the solid and high-class feeling of the building. (2) When used in a place where it is easily exposed to sunlight daily, the unevenness feeling, three-dimensional feeling, etc. can be enhanced by the effect of emphasizing the shadow more. (3) Even when used in a place where the shadow of the pattern by sunlight or lighting is weak, such as in bad weather, evening, the north side where sunlight is hard to reach, or indoors, the unevenness feeling, three-dimensional feeling, etc. can be sufficiently felt by the effect of complementing the shadow. (4) It can produce a real and natural texture. (5) It can also achieve effects such as being able to have a more complex and elaborate finish and an appearance expression with a natural look.
[0023] (Details) Hereinafter, the details of the building material 1 according to this embodiment will be described.
[0024] FIG. 1A is a front view showing a part of the building material 1. FIG. 1B is a longitudinal sectional view showing a part of the building material 1. In the construction state, the building material 1 has a horizontal joint part 10 and a plurality of pattern parts 20 on its surface. The plurality of pattern parts 20 include a plurality of upper pattern parts 21 and a plurality of lower pattern parts 22. In the building material 1, a dark part X is partially provided in the horizontal joint part 10.
[0025] [Horizontal joint part] The building material 1 has one or more horizontal joint parts 10 on its surface. The horizontal joint part 10 is a joint extending horizontally in the building material 1 in the construction state, that is, a joint extending in the horizontal direction. At least one of the horizontal joint parts 10 may be a continuous joint reaching both ends of the building material 1.
[0026] [Pattern part] The pattern part 20 refers to a part of the surface where a pattern is applied. The pattern of the pattern part 20 is not particularly limited, and examples include a natural stone pattern, a brick pattern, a wood grain pattern, etc. The building material 1 has a plurality of pattern parts 20 on its surface. The plurality of pattern parts 20 include a plurality of upper pattern parts 21 and a plurality of lower pattern parts 22. The upper pattern part 21 is a part adjacent upward along the horizontal joint part 10. The lower pattern part 22 is a part adjacent downward along the horizontal joint part 10.
[0027] The plurality of pattern parts 20 may include a pattern part protruding to the surface side (hereinafter also referred to as a protruding pattern part P). That is, each pattern part 20 may be a protruding pattern part P or a pattern part not protruding to the surface side (hereinafter also referred to as a non-protruding pattern part Q). The upper pattern part 21 and the lower pattern part 22 in FIG. 1B are both protruding pattern parts P. The shape of the longitudinal section of the protruding pattern part P is, for example, a trapezoidal shape, a rectangular shape, etc. Note that the surface of the protruding pattern part P may be flat or may have an uneven pattern formed. The non-protruding pattern part Q may be only printing or painting.
[0028] In the upper handle portion 21 and the lower handle portion 22, the height of the surface of the protruding handle portion P from the surface of the adjacent horizontal joint portion 10 is defined as the "protrusion height". The protrusion heights of the respective plurality of handle portions 20 may be the same or different.
[0029] As shown in FIG. 1B, the height difference between the surface of the upper handle portion 21 and the surface of the lower handle portion 22 is defined as the "height difference H". When both the upper handle portion 21 and the lower handle portion 22 are the protruding handle portion P, the height difference H is the absolute value of the difference in the protrusion heights between the upper handle portion 21 and the lower handle portion 22. When the protrusion heights of the upper handle portion 21 and the lower handle portion 22 are the same, the height difference H = 0.
[0030] (Dark-colored portion) The dark-colored portion X is partially provided in the horizontal joint portion 10. The dark-colored portion X may be provided in a substantially uniform dispersion or a non-uniform dispersion in the horizontal joint portion 10.
[0031] Further, it is preferable that the dark-colored portion X is provided not only in the horizontal joint portion 10 but also including at least one surface of the upper handle portion 21 and the lower handle portion 22 from the horizontal joint portion 10. By providing the dark-colored portion X in the horizontal joint portion 10 and the upper handle portion 21 and the lower handle portion 22 in this way, the horizontal joint portion 10, the upper handle portion 21, and the lower handle portion 22 appear to be integrated, etc., so that the conspicuousness such as horizontal joint misalignment can be further reduced.
[0032] The dark-colored portion X in FIG. 1B is provided in the horizontal joint portion 10, the entire inclined surface of the trapezoidal cross-section of the upper handle portion 21, the entire inclined surface of the trapezoidal cross-section of the lower handle portion 22, and a part of the upper surface of the trapezoidal cross-section.
[0033] In FIGS. 2 and 3, the range where the dark-colored portion X is provided is shown as a pseudo-shadow range Y.
[0034] In the building material 1, it is preferable that the lower the lightness of the dark-colored portion X is set as the height difference H between the upper handle portion 21 and the lower handle portion 22 is larger. By setting the lightness of the dark-colored portion X in this way, the above-described effects of the building material 1 can be further enhanced.
[0035] "Brightness", specifically, is L * a * b * Brightness L in the color space * is meant. Brightness can be measured, for example, using a spectrophotometer.
[0036] Regarding the dark-colored part X of the building material 1, the ratio of the difference between the highest brightness and the lowest brightness to the lowest brightness ((highest brightness - lowest brightness) / lowest brightness) (hereinafter also referred to as brightness difference (I)) is preferably 3% or more, more preferably 5% or more, still more preferably 10% or more, and particularly preferably 15% or more. By setting the brightness difference in the dark-colored part X in this way, the above-described effects of the building material 1 can be enhanced more.
[0037] Also, the surfaces of the upper handle part 21 and the lower handle part 22 are preferably set to have higher brightness as the protrusion height thereof is larger. By setting the brightness of the surfaces of the upper handle part 21 and the lower handle part 22 in this way, the above-described effects of the building material 1 can be enhanced more.
[0038] Fig. 2 shows an example of the combination of the horizontal joint part 10 and the handle part 20 in the building material 1 of this embodiment.

Including the case of D, the horizontal joint portion 10 at the location where the upper handle portion 21 or the lower handle portion 22 is the non-protruding handle portion Q can be regarded as an extension of the horizontal joint portion 10 at other locations adjacent in the horizontal direction and having the same shape.
[0040] In A to D of FIG. 2, the height difference H between the upper handle portion 21 and the lower handle portion 22 increases from A to D.

[0042] In E to H of FIG. 2, the height difference H between the upper handle portion 21 and the lower handle portion 22 increases from E to H. In this case, it is preferable that the lightness of the dark portion X is set lower from E to H. By setting the lightness of the dark portion X in this way, the above-described effects of the building material 1 can be enhanced more.

In the building material 1, the more the horizontal joint portion 10 extends straight and looks uniform, the more conspicuous the deviation of the horizontal joint portions 10 between adjacent building materials 1 at the joint (vertical joint) becomes. That is, when the horizontal joint portion 10 is a continuous joint, the benefits of adopting the present invention are great.
[0048] The building material 1 of this embodiment can be manufactured by forming the dark-colored portion X having the above-described characteristics on the surface of the building material. Examples of the method for forming the dark-colored portion X include methods such as painting by inkjet painting, spray painting, etc.
