[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-13580 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the invention described in Patent Document 1, light and dark areas are formed by the difference in height of the surface molding, which has the disadvantage of limiting the design.

[0005] In this situation, there is a demand for a method for reducing various conspicuities in building materials, such as those at joints, those caused by pattern tendencies, and those caused by misalignment of horizontal joints on either side of a sealant, without restricting the design.

[0006] The present invention has been made in light of the above circumstances, and its object is to provide a building material that can reduce the visibility of joints, pattern tendencies, misalignment of horizontal joints, etc. [Means for solving the problem]

[0007] A building material according to one embodiment of the present disclosure has, on its surface, one or more horizontal joints extending laterally in an installed state and a plurality of pattern portions. The pattern portions have a plurality of upper pattern portions adjacent to the horizontal joints above and a plurality of lower pattern portions adjacent to the horizontal joints below. The horizontal joints are partially provided with dark portions. The plurality of handles include a handle protruding toward the surface side, and further include the plurality of upper handles and the plurality of lower handles having different protruding heights. The greater the difference in height between the upper handles and the lower handles, the lower the brightness of the dark color portion is set.

[0008] A building material according to another embodiment of the present disclosure has, on its surface, one or more horizontal joints extending laterally in an installed state and multiple pattern portions. The pattern portions have multiple upper pattern portions adjacent to the horizontal joints above and multiple lower pattern portions adjacent to the horizontal joints below. The horizontal joints are partially provided with dark color portions. The multiple pattern portions include pattern portions that protrude toward the surface, and the height difference between the multiple upper pattern portions and the multiple lower pattern portions located on either side of the horizontal joints changes in the direction in which the horizontal joints extend. The greater the height difference between the upper pattern portions and the lower pattern portions, the lower the brightness of the dark color portions is set.

[0011] It is preferable that the brightness of the surfaces of the upper and lower stalks is set to be higher as the protruding height increases.

[0012] It is preferable that the building material has a rectangular shape when viewed from the front, and that one or more dark colored portions are provided on at least one of both end portions in the direction in which the horizontal joint portion extends.

[0013] It is preferable that the dark color portion is provided from the horizontal joint portion to include the surface of at least one of the upper pattern portion and the lower pattern portion.

[0014] At least one of the horizontal joints is preferably a through joint that reaches both ends of the building material. [Effects of the Invention]

[0015] According to the present invention, it is possible to reduce the visibility of joints, pattern quirks, misalignment of horizontal joints, etc. in building materials. Furthermore, according to the present invention, it is possible to enhance the sense of unevenness, three-dimensionality, etc. in building materials. According to such invention, there are few restrictions on the design of building materials. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] <Construction materials> The building material 1 according to this embodiment will be described below with reference to the drawings. The following embodiment is merely one of various embodiments of the present invention. The following embodiment can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved. Furthermore, each diagram described in the following embodiment is a schematic diagram, and the ratios of the size and thickness of each component in the diagram do not necessarily reflect the actual dimensional ratios. In the following, "front view" means a view from the front of the object.

[0018] (overview) In order to solve the above-mentioned problems, the inventors conducted extensive research and discovered that in building materials having horizontal joints and pattern portions on the surface, the prominence of each portion can be controlled by varying the shading of the horizontal joints, etc., and thus completed the present invention.

[0019] The building material 1 of the present invention has, on its surface, one or more horizontal joints 10 that extend laterally when in construction, and multiple handles 20. The handles 20 have multiple upper handles 21 adjacent to the horizontal joints 10 above, and multiple lower handles 22 adjacent to the horizontal joints 10 below. In the building material 1, the horizontal joints 10 are partially provided with dark colored portions X.

[0020] "Dark colored portion" refers to the horizontal joint and patterned portion of the building material that is darker in color than the surrounding horizontal joint and patterned portions. Specifically, the dark colored portion X is a portion of the original building material where the color of the horizontal joint, pattern, etc. has been made darker by printing, painting, etc.

[0021] The building material 1 of the present invention can reduce the visibility of joints, pattern quirks, misalignment of horizontal joints, etc. The reason why the building material 1 of the present invention, which has the above-mentioned configuration, achieves the above-mentioned effect is not entirely clear, but it is thought that this is because, for example, by darkening the color of a portion of the horizontal joint portion 10, a conspicuous portion is created within the building material, and the eye can be diverted away from the joint, even when the joint becomes darker and more noticeable due to manufacturing or construction errors. Furthermore, it is thought that controlling the shading of the recesses can accommodate building materials with a variety of designs.

[0022] Furthermore, according to the present invention, by partially providing dark-colored portions X in the horizontal joint portions 10, the unevenness, three-dimensionality, etc. of the building material 1 can be enhanced. By enhancing the unevenness, three-dimensionality, etc. in this way, the building material 1 (1) can enhance the sense of solidity and luxury of the building. (2) When used in a place that is exposed to sunlight on a daily basis, the unevenness, three-dimensionality, etc. can be enhanced by further emphasizing shadows. (3) Even when used in a place where the shadows of patterns caused by sunlight or lighting are weak, such as in bad weather or in the evening, on a north-facing surface that is not exposed to sunlight, or indoors, the unevenness, three-dimensionality, etc. can be fully perceived by complementing the shadows. (4) A realistic and natural texture can be created. (5) It can also achieve effects such as more complex and elaborate finishes and natural-looking exterior expressions.

[0023] (detail) The construction material 1 according to this embodiment will be described in detail below.

[0024] FIG. 1A is a front view showing a portion of the building material 1. FIG. 1B is a longitudinal cross-sectional view showing a portion of the building material 1. In the installed state, the building material 1 has a horizontal joint portion 10 and multiple handle portions 20 on its surface. The multiple handle portions 20 have multiple upper handle portions 21 and multiple lower handle portions 22. In the building material 1, the horizontal joint portion 10 is partially provided with a dark color portion X.

[0025] [Horizontal joint] The building material 1 has one or more horizontal joints 10 on its surface. The horizontal joints 10 are joints that extend horizontally, that is, joints that extend in the horizontal direction, in the installed building material 1. At least one of the horizontal joints 10 may be a through joint that extends to both ends of the building material 1.

[0026] [Handle] The handle portion 20 refers to a portion on which a pattern is applied on the surface. The pattern of the handle portion 20 is not particularly limited, but examples include natural stone, brick, and wood grain patterns. The building material 1 has a plurality of handle portions 20 on its surface. The plurality of handle portions 20 have a plurality of upper handle portions 21 and a plurality of lower handle portions 22. The upper handle portions 21 are adjacent portions above and along the horizontal joint portion 10. The lower handle portions 22 are adjacent portions below and along the horizontal joint portion 10.

[0027] The multiple handle portions 20 may include handle portions that protrude toward the surface (hereinafter also referred to as protruding handle portions P). That is, each handle portion 20 may be a protruding handle portion P or a handle portion that does not protrude toward the surface (hereinafter also referred to as a non-protruding handle portion Q). The upper handle portion 21 and the lower handle portion 22 in FIG. 1B are both protruding handle portions P. The shape of the longitudinal cross section of the protruding handle portion P is, for example, a trapezoidal shape, a rectangular shape, etc. The surface of the protruding handle portion P may be flat or may have an uneven pattern. The non-protruding handle portion Q may be simply printed or painted.

[0028] In the upper stalk portion 21 and the lower stalk portion 22, the height of the surface of the protruding stalk portion P from the surface of the adjacent horizontal joint portion 10 is referred to as the "protruding height." The protruding heights of the multiple stalk portions 20 may be the same or different.

[0029] 1B, the difference in height between the surface of the upper stalk 21 and the surface of the lower stalk 22 is referred to as "height difference H." When both the upper stalk 21 and the lower stalk 22 are protruding stalks P, the height difference H is the absolute value of the difference in protruding height between the upper stalk 21 and the lower stalk 22. When the protruding heights of the upper stalk 21 and the lower stalk 22 are the same, the height difference H=0.

[0030] (Dark colored area) The dark color portions X are provided partially in the horizontal joint portion 10. The dark color portions X may be provided so as to be dispersed approximately uniformly in the horizontal joint portion 10, or may be provided so as to be dispersed unevenly.

[0031] Furthermore, it is preferable that the dark color portion X is provided not only in the horizontal joint portion 10 but also on the surface of at least one of the horizontal joint portion 10 and the upper pattern portion 21 and the lower pattern portion 22. In this way, by providing the dark color portion X in the horizontal joint portion 10 and the upper pattern portion 21 and the lower pattern portion 22, the horizontal joint portion 10 and the upper pattern portion 21 and the lower pattern portion 22 appear to be integrated, which can further reduce the visibility of misalignment of the horizontal joints.

[0032] The dark color portion X in FIG. 1B is provided on the horizontal joint portion 10, the entire slope of the trapezoidal cross section of the upper stalk portion 21, the entire slope of the trapezoidal cross section of the lower stalk portion 22, and part of the upper surface of the trapezoidal cross section.

[0033] 2 and 3, the range in which the dark color portion X is provided is shown as a pseudo shadow range Y.

[0034] In the building material 1, it is preferable that the greater the height difference H between the upper handle portion 21 and the lower handle portion 22, the lower the brightness of the dark color portion X. By setting the brightness of the dark color portion X in this manner, the above-mentioned effects of the building material 1 can be further enhanced.

[0035] "Lightness" specifically refers to L * a * b * Lightness L in the color system *The brightness can be measured, for example, using a spectrophotometer.

[0036] For the dark color portion X of the building material 1, the ratio of the difference between the highest and lowest lightness to the lowest lightness ((highest lightness - lowest lightness) / lowest lightness) (hereinafter also referred to as lightness difference (I)) is preferably 3% or more, more preferably 5% or more, even more preferably 10% or more, and particularly preferably 15% or more. By setting the lightness difference in the dark color portion X in this manner, the above-mentioned effects of the building material 1 can be further enhanced.

[0037] Furthermore, it is preferable that the brightness of the surfaces of the upper and lower handles 21 and 22 be set higher the greater the protruding height. By setting the brightness of the surfaces of the upper and lower handles 21 and 22 in this manner, the above-mentioned effects of the building material 1 can be further enhanced.

[0038] FIG. 2 shows an example of a combination of the horizontal joint portion 10 and the handle portion 20 in the building material 1 of this embodiment.

[0039] In Figure 2, A is the case where the upper stalk portion 21 and the lower stalk portion 22 have the same protruding height (height difference H = 0), and the pseudo shadow range Y is the horizontal joint portion 10 and the entire slope of the upper stalk portion 21 adjacent to the horizontal joint portion 10, and the entire slope of the lower stalk portion 22 adjacent to the horizontal joint portion 10. A' is the case where the height difference H = 0, and the pseudo shadow range Y is the entire slope of the horizontal joint portion 10 and the lower stalk portion 22 adjacent to the horizontal joint portion 10. In A", the height difference H = 0, and the pseudo shadow area Y is the entire slope of the horizontal joint portion 10 and the upper pattern portion 21 adjacent to the horizontal joint portion 10. In B, the upper pattern portion 21 protrudes higher than the lower pattern portion 22 (height difference H), and the pseudo shadow area Y is the entire slope of the horizontal joint portion 10 and the upper pattern portion 21 adjacent to the horizontal joint portion 10, and the entire slope of the lower pattern portion 22 adjacent to the horizontal joint portion 10 and a part of the surface side surface adjacent thereto. In C, the upper pattern portion 21 protrudes higher than the lower pattern portion 22 (height difference H), and the pseudo shadow area Y is the entire slope of the horizontal joint portion 10 and the upper pattern portion 21 adjacent to the horizontal joint portion 10. The pseudo-shadow range Y is the entire slope, and the entire slope of the lower pattern portion 22 adjacent to the horizontal joint portion 10, and a part of the surface of the front side adjacent to this. In D, the upper pattern portion 21 is the protruding pattern portion P, and the lower pattern portion 22 is the non-protruding pattern portion Q (height difference H), and the pseudo-shadow range Y is the horizontal joint portion 10, the entire slope of the upper pattern portion 21 adjacent to the horizontal joint portion 10, and a part of the surface of the lower pattern portion 22 adjacent to the horizontal joint portion 10. Including the case of D, the horizontal joint portion 10 at the point where the upper pattern portion 21 or the lower pattern portion 22 is the non-protruding pattern portion Q is an extension of the horizontal joint portion 10 at another laterally adjacent point, and can be considered to have the same shape.

[0040] 2A to 2D, the height difference H between the upper handle portion 21 and the lower handle portion 22 increases from A to D. In this case, it is preferable that the brightness of the dark color portion X is set to decrease from A to D. By setting the brightness of the dark color portion X in this manner, the above-mentioned effects of the building material 1 can be further enhanced.

[0041] 2, E indicates that the upper pattern portion 21 protrudes higher than the lower pattern portion 22 (height difference H), and the pseudo shadow range Y is the horizontal joint portion 10 and the entire slope of the upper pattern portion 21 adjacent to the horizontal joint portion 10, and the entire slope of the lower pattern portion 22 adjacent to the horizontal joint portion 10 and the entire adjacent front surface. F indicates that the lower pattern portion 22 protrudes higher than the upper pattern portion 21 (height difference H), and the pseudo shadow range Y is the horizontal joint portion 10 and the entire slope of the upper pattern portion 21 adjacent to the horizontal joint portion 10 and the entire adjacent front surface, and the entire slope of the lower pattern portion 22 adjacent to the horizontal joint portion 10. In G, the lower pattern portion 22 protrudes higher than the upper pattern portion 21 (height difference H), and the pseudo shadow range Y is the horizontal joint portion 10, the entire slope of the upper pattern portion 21 adjacent to the horizontal joint portion 10, and a portion of the surface side surface adjacent thereto, and the entire slope of the lower pattern portion 22 adjacent to the horizontal joint portion 10. In H, the upper pattern portion 21 is the non-protruding pattern portion Q, and the lower pattern portion 22 is the protruding pattern portion P (height difference H), and the pseudo shadow range Y is the horizontal joint portion 10, the portion of the surface of the upper pattern portion 21 adjacent to the horizontal joint portion 10, and the entire slope of the lower pattern portion 22 adjacent to the horizontal joint portion 10.

[0042] 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 brightness of the dark color portion X is set to decrease from E to H. By setting the brightness of the dark color portion X in this manner, the above-mentioned effects of the building material 1 can be further enhanced.

[0043] In the building material 1 of this embodiment, the multiple handles 20 may include multiple upper handles 21 and multiple lower handles with different protruding heights, as shown in B, C, D, E, F, G, and H of Fig. 2. In this case, the above-mentioned effects of the building material 1 can be further enhanced. Furthermore, the building material 1 can express shading of various intensities, natural shading, etc.

[0044] An example of a building material 1 according to this embodiment is shown in Fig. 3. In Fig. 3, the dark colored portions X in the horizontal joint portion 10 and the handle portion 20 are indicated by dots. In Fig. 3, F indicates the FF cross section, E indicates the EE cross section, and C indicates the CC cross section. F and C in Fig. 3 include joints (horizontal joints).

[0045] The building material 1 in Fig. 3 has a plurality of handle portions 20, including handle portions 20 that protrude toward the surface, and the height difference H between a plurality of upper handle portions 21 and a plurality of lower handle portions 22, which are positioned on either side of the horizontal joint portion 10, changes in the direction in which the horizontal joint portion 10 extends. By configuring the building material 1 in this way, the above-mentioned effects can be further enhanced.

[0046] The shape of the building material 1 is not particularly limited, but may be, for example, rectangular when viewed from the front. When the building material 1 is rectangular when viewed from the front, it is preferable that one or more dark colored portions be provided on at least one of the end portions of the building material 1 in the direction in which the horizontal joint portion 10 extends. By providing a dark colored portion X on at least one of the end portions, the above-mentioned effects of the building material 1 can be further enhanced. It is more preferable that the building material 1 has a dark colored portion X on both end portions, and even more preferable that multiple dark colored portions X be provided on both end portions.

[0047] In the building material 1, at least one of the horizontal joints 10 is preferably a through joint that reaches both ends of the building material 1 in order to reduce the visibility of the joint (horizontal joint). In the building material 1, the more straight and uniform the horizontal joints 10 are, the more noticeable the misalignment of the horizontal joints 10 between adjacent building materials 1 at the joint (vertical joint) becomes. In other words, the benefit of adopting the present invention is great when the horizontal joints 10 are through joints.

[0048] The building material 1 of this embodiment can be manufactured by forming the dark color portion X having the above-mentioned characteristics on the surface of the building material. Examples of a method for forming the dark color portion X include a painting method such as inkjet painting or spray painting.

[0049] Fig. 4A is a photograph showing the building material 1 of the present invention having a dark color portion X. Fig. 4B is a photograph showing a conventional building material having no dark color portion X.

[0050] The dotted frames in Figures 4A and 4B indicate portions having similar patterns in the horizontal joint portion 10, the upper pattern portion 21, and the lower pattern portion 22. As can be seen from a comparison between Figures 4A and 4B, the building material 1 of the present invention in Figure 4A, which has the above-mentioned dark color portion X, expresses shading that emphasizes the difference in elevation compared to the building material in Figure 4B, which does not have the dark color portion X.
