特開２０１５−７１９２７号公報JP-A-2015-71927

上記のような従来の外装材では、凹凸からなる模様を化粧面に設けている。このような凹凸模様を変更する場合、例えばエンボスロールやプレス金型等の外装材の製造に用いる部材を変更する必要がある。このため、容易に模様を変更することが難しく、意匠の多様性を確保することが難しい。 In the conventional exterior material as described above, a pattern composed of unevenness is provided on the decorative surface. When changing such an uneven pattern, it is necessary to change a member used for manufacturing an exterior material such as an embossed roll or a press die. Therefore, it is difficult to easily change the pattern, and it is difficult to secure the diversity of the design.

本発明は、上記のような課題を解決するためになされたものであり、その目的は、意匠の多様性をより容易に確保することができる外装材及びその製造方法を提供することである。 The present invention has been made to solve the above problems, and an object of the present invention is to provide an exterior material and a method for manufacturing the same, which can more easily secure a variety of designs.

また、本発明に係る外装材の製造方法は、建物の外面に表れる化粧面を有し、線状の凹凸により表された第１模様と、線状の塗膜により表された第２模様とが化粧面に設けられた外装材を製造する方法であって、化粧面に第１模様を設ける工程と、化粧面に第１模様を設ける前又は設けた後に、印刷機により化粧面に第２模様を形成する工程とを含み、第１及び第２模様は、同じ方向に延在する線状の模様であり、互いに非同期で設けられており、第１模様の凸部間のピッチの平均値が第２模様を構成する塗膜間のピッチの平均値に実質的に一致する。 The exterior material according to the present invention is an exterior material having a decorative surface that appears on the outer surface of a building, and the decorative surface is represented by a first pattern represented by linear unevenness and a linear coating film. A second pattern is provided, and the first and second patterns are linear patterns extending in the same direction and are provided asynchronously with each other , and the average pitch between the protrusions of the first pattern is averaged. The value substantially matches the average value of the pitches between the coating films constituting the second pattern .
Further, the method for manufacturing an exterior material according to the present invention has a decorative surface appearing on the outer surface of a building, and has a first pattern represented by linear unevenness and a second pattern represented by a linear coating film. Is a method of manufacturing the exterior material provided on the decorative surface, in which the step of providing the first pattern on the decorative surface and the second pattern on the decorative surface by a printing machine before or after the first pattern is provided on the decorative surface. The first and second patterns include a step of forming a pattern, which are linear patterns extending in the same direction and are provided asynchronously with each other, and the average value of the pitches between the convex portions of the first pattern. Substantially matches the average value of the pitches between the coating films constituting the second pattern.

本発明の外装材及びその製造方法によれば、凹凸により表された第１模様と塗膜により表された第２模様とが互いに非同期で設けられているので、第１模様に制限されずに第２模様により数多くの意匠を表現することができる。これにより、意匠の多様性をより容易に確保することができる。 According to the exterior material of the present invention and the manufacturing method thereof , the first pattern represented by the unevenness and the second pattern represented by the coating film are provided asynchronously with each other, so that the pattern is not limited to the first pattern. Many designs can be expressed by the second pattern. As a result, the diversity of designs can be secured more easily.

以下、本発明を実施するための形態について、図面を参照して説明する。
実施の形態１．
図１は本発明の実施の形態１による外装材１（屋根材）を示す斜視図であり、図２は図１の外装材１が屋根下地の上に並べて配置された状態を示す断面図であり、図３は図２の外装材１を示す斜視図である。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1.
FIG. 1 is a perspective view showing an exterior material 1 (roof material) according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a state in which the exterior material 1 of FIG. 1 is arranged side by side on a roof base. Yes, FIG. 3 is a perspective view showing the exterior material 1 of FIG.

図１に示す外装材１は、長手方向１Ｌ（幅方向）及び短手方向１Ｓ（奥行方向）を有する平面視略矩形の瓦調形状（波板状）の屋根用部材である。すなわち、本実施の形態の１の外装材１は、屋根下地の上に配置される屋根材である。外装材１は、金属板を素材とする外装材本体１０と、外装材本体１０の裏面全体又は裏面の一部に設けられた芯材（図示せず）とを有している。 The exterior material 1 shown in FIG. 1 is a roof tile-like (corrugated plate-like) member having a longitudinal direction of 1 L (width direction) and a lateral direction of 1 S (depth direction) and having a substantially rectangular plan view. That is, the exterior material 1 of 1 of the present embodiment is a roofing material arranged on the roof base. The exterior material 1 has an exterior material main body 10 made of a metal plate, and a core material (not shown) provided on the entire back surface or a part of the back surface of the exterior material main body 10.

外装材本体１０の素材である金属板としては、溶融Ｚｎ系めっき鋼板、溶融Ａｌめっき鋼板、溶融Ｚｎ系めっきステンレス鋼板、溶融Ａｌめっきステンレス鋼板、ステンレス鋼板、Ａｌ板、Ｔｉ板、塗装溶融Ｚｎ系めっき鋼板、塗装溶融Ａｌめっき鋼板、塗装溶融Ｚｎ系めっきステンレス鋼板、塗装溶融Ａｌめっきステンレス鋼板、塗装ステンレス鋼板、塗装Ａｌ板又は塗装Ｔｉ板を用いることができる。 As the metal plate which is the material of the exterior material main body 10, the molten Zn-based plated steel sheet, the molten Al-plated steel sheet, the molten Zn-based plated stainless steel sheet, the molten Al-plated stainless steel sheet, the stainless steel sheet, the Al plate, the Ti plate, and the painted molten Zn-based A plated steel sheet, a painted molten Al plated steel sheet, a painted molten Zn-based plated stainless steel sheet, a painted molten Al plated stainless steel sheet, a painted stainless steel sheet, a painted Al plate, or a painted Ti plate can be used.

芯材は、例えば発泡樹脂等により構成されるものであり、外装材本体１０の裏面に直接接合されている。芯材としては、特に制限が無く、ウレタン、フェノール、ヌレート樹脂等を用いることができる。外装材本体１０の裏面に芯材が設けられることで、瓦調形状の外装材本体１０が踏み潰れにくくされている。例えば外装材本体１０が平板形状の場合等には、芯材が省略されていてもよい。 The core material is made of, for example, foamed resin, and is directly bonded to the back surface of the exterior material main body 10. The core material is not particularly limited, and urethane, phenol, nurate resin and the like can be used. By providing the core material on the back surface of the exterior material body 10, the tile-shaped exterior material body 10 is less likely to be trampled. For example, when the exterior material main body 10 has a flat plate shape, the core material may be omitted.

外装材１は、図２及び図３に示すように、他の外装材１とともに屋根下地の上に並べて配置される。各外装材１は、長手方向１Ｌが屋根の軒方向２に沿い、短手方向１Ｓが屋根の軒棟方向３に沿うように屋根下地の上に配置される。すなわち、本実施の形態の屋根材１では、長手方向１Ｌが軒方向に相当し、短手方向１Ｓが軒棟方向に相当する。 As shown in FIGS. 2 and 3, the exterior material 1 is arranged side by side on the roof base together with the other exterior materials 1. Each exterior material 1 is arranged on the roof base so that the longitudinal direction 1L is along the roof eaves direction 2 and the lateral direction 1S is along the roof eaves direction 3. That is, in the roofing material 1 of the present embodiment, the longitudinal direction 1L corresponds to the eaves direction, and the lateral direction 1S corresponds to the eaves building direction.

図２に特に表れているように、各外装材１の短手方向１Ｓの端部には、外装材本体１０を構成する金属板の端部が折り曲げられて形成された第１及び第２嵌合部１１，１２が設けられている。図２に示すように、各外装材１の第１及び第２嵌合部１１，１２が互いに嵌合されることで、屋根の軒棟方向に各外装材１が互いに連結される。 As particularly shown in FIG. 2, the first and second fittings formed by bending the end portions of the metal plates constituting the exterior material main body 10 are formed at the end portions of each exterior material 1 in the lateral direction 1S. Joint portions 11 and 12 are provided. As shown in FIG. 2, by fitting the first and second fitting portions 11 and 12 of the exterior materials 1 to each other, the exterior materials 1 are connected to each other in the eaves direction of the roof.

外装材本体１０の表面は、屋根の外面に表れる化粧面１３を構成する。各外装材１の化粧面１３には、以下の図４及び図５に示す第１及び第２模様４，５が設けられている。 The surface of the exterior material main body 10 constitutes a decorative surface 13 that appears on the outer surface of the roof. The decorative surface 13 of each exterior material 1 is provided with the first and second patterns 4 and 5 shown in FIGS. 4 and 5 below.

図４は、図１の外装材１の化粧面１３に設けられる第１模様４の例を示す説明図である。第１模様４は、凹凸により表された軒棟方向３に延在する線状の模様である。具体的には、第１模様４は、軒棟方向３に線状に延在する複数の凸部４０と、各凸部４０の間に設けられた複数の凹部４１とによって構成されている。エンボス加工及びプレス加工を含む機械加工を外装材本体１０又はその素材金属板に施すことにより、化粧面１３に第１模様４を設けることができる。 FIG. 4 is an explanatory view showing an example of the first pattern 4 provided on the decorative surface 13 of the exterior material 1 of FIG. The first pattern 4 is a linear pattern extending in the eaves building direction 3 represented by unevenness. Specifically, the first pattern 4 is composed of a plurality of convex portions 40 extending linearly in the eaves building direction 3 and a plurality of concave portions 41 provided between the convex portions 40. The first pattern 4 can be provided on the decorative surface 13 by performing machining including embossing and pressing on the exterior material main body 10 or the material metal plate thereof.

図５は、図１の外装材１の化粧面１３に設けられる第２模様５の例を示す説明図である。第２模様５は、塗膜により表された軒棟方向３に延在する線状の模様である。具体的には、第２模様５は、軒棟方向３に線状に延在する複数の第１塗膜５０によって構成されている。この第２模様５の第１塗膜５０の配置パターンは、第１模様４の凸部４０の配置パターンと異なるようにされている。凸版印刷、平版印刷、凹版印刷及びインクジェット印刷を含む印刷機による印刷を外装材本体１０又はその素材金属板に施すことにより、化粧面１３に第２模様５を設けることができる。 FIG. 5 is an explanatory view showing an example of a second pattern 5 provided on the decorative surface 13 of the exterior material 1 of FIG. The second pattern 5 is a linear pattern extending in the eaves building direction 3 represented by the coating film. Specifically, the second pattern 5 is composed of a plurality of first coating films 50 extending linearly in the eaves building direction 3. The arrangement pattern of the first coating film 50 of the second pattern 5 is different from the arrangement pattern of the convex portion 40 of the first pattern 4. The second pattern 5 can be provided on the decorative surface 13 by performing printing by a printing machine including letterpress printing, lithographic printing, intaglio printing, and inkjet printing on the exterior material main body 10 or the material metal plate thereof.

第１及び第２模様４，５を化粧面１３に設ける順序は任意である。換言すると、第１模様４を化粧面１３に設ける前に第２模様５を化粧面１３に設けてもよいし、第１模様４を化粧面１３に設けた後に第２模様５を化粧面１３に設けてもよい。すなわち、本実施の形態１の外装材１を製造する方法は、化粧面１３に第１模様４を設ける工程と、化粧面１３に第１模様４を設ける前又は設けた後に、印刷機により化粧面１３に第２模様１４を形成する工程とを含む。後述のように、第１及び第２模様４，５は、互いに非同期で設けられる。 The order in which the first and second patterns 4 and 5 are provided on the decorative surface 13 is arbitrary. In other words, the second pattern 5 may be provided on the decorative surface 13 before the first pattern 4 is provided on the decorative surface 13, or the second pattern 5 may be provided on the decorative surface 13 after the first pattern 4 is provided on the decorative surface 13. It may be provided in. That is, in the method of manufacturing the exterior material 1 of the first embodiment, a step of providing the first pattern 4 on the decorative surface 13 and a makeup using a printing machine before or after providing the first pattern 4 on the decorative surface 13. A step of forming the second pattern 14 on the surface 13 is included. As will be described later, the first and second patterns 4 and 5 are provided asynchronously with each other.

屋根材本体１０の素材が塗装金属板である場合、第２模様５の第１塗膜５０の色は、塗装金属板の塗装色の非同系色であってもよいが、塗装金属板の塗装色と同系色とすることができる。ここで言う同系色は、色差ΔＥが１０以下の色と定義することができる。２つの色の色差ΔＥは、それらの明度（Ｌ値）、赤み（ａ値）及び黄み（ｂ値）を用いて、（ΔＬ２＋Δａ２＋Δｂ２）−１／２と表すことができる。ΔＬは２つの色のＬ値の差であり、Δａは２つの色のａ値の差であり、Δｂは２つの色のｂ値の差である。 When the material of the roofing material main body 10 is a painted metal plate, the color of the first coating film 50 of the second pattern 5 may be a non-similar color of the painting color of the painted metal plate, but the painting of the painted metal plate It can be similar to the color. The similar colors referred to here can be defined as colors having a color difference ΔE of 10 or less. The color difference ΔE between the two colors can be expressed as (ΔL 2 + Δa 2 + Δb 2 ) -1 / 2 using their lightness (L value), redness (a value) and yellowness (b value). ΔL is the difference between the L values of the two colors, Δa is the difference between the a values of the two colors, and Δb is the difference between the b values of the two colors.

次に、図６は、図４及び図５の第１及び第２模様４，５が重ねられた状態を示す説明図である。上述のように第２模様５の第１塗膜５０の配置パターンが第１模様４の凸部４０及び凹部４１の配置パターンと異なるため、図６に示すように第１及び第２模様４，５が重ねられて化粧面１３に設けられても、第１及び第２模様４，５は互いに同期しない。すなわち、第１及び第２模様４，５は互いに非同期で化粧面１３に設けられている。なお、図６では、第１及び第２模様４，５の個々の状態も現れるように第１模様４の一部のみが第２模様５の一部に重なるように示している。しかしながら、第１及び第２模様４，５の両方の全体が互いに重なるように化粧面１３に設けることができる。 Next, FIG. 6 is an explanatory diagram showing a state in which the first and second patterns 4 and 5 of FIGS. 4 and 5 are overlapped. As described above, the arrangement pattern of the first coating film 50 of the second pattern 5 is different from the arrangement pattern of the convex portion 40 and the concave portion 41 of the first pattern 4, and therefore, as shown in FIG. 6, the first and second patterns 4 and Even if the 5s are overlapped and provided on the decorative surface 13, the first and second patterns 4 and 5 are not synchronized with each other. That is, the first and second patterns 4 and 5 are provided on the decorative surface 13 asynchronously with each other. In FIG. 6, only a part of the first pattern 4 is shown to overlap a part of the second pattern 5 so that the individual states of the first and second patterns 4 and 5 also appear. However, both the first and second patterns 4 and 5 can be provided on the decorative surface 13 so as to overlap each other.

ここで、第１及び第２模様４，５が同期するとは、第２模様５の第１塗膜５０が第１模様４の凸部４０に完全に重なることを意味する。すなわち、第１及び第２模様４，５が互いに非同期で化粧面１３に設けられるとは、第２模様５の第１塗膜５０の少なくとも一部が第１模様４の凸部４０からはみ出るように、第１及び第２模様４，５が化粧面１３に設けられることを意味する。 Here, the synchronization of the first pattern and the second patterns 4 and 5 means that the first coating film 50 of the second pattern 5 completely overlaps the convex portion 40 of the first pattern 4. That is, the fact that the first and second patterns 4 and 5 are provided on the decorative surface 13 asynchronously with each other means that at least a part of the first coating film 50 of the second pattern 5 protrudes from the convex portion 40 of the first pattern 4. It means that the first and second patterns 4 and 5 are provided on the decorative surface 13.

一方、第１及び第２模様４，５の両方が軒棟方向３に延在する線状の模様であることから、第１及び第２模様４，５が重ねられても線状のイメージが維持される。第１模様４の凸部４０間のピッチ（離間距離）と第２模様５の第１塗膜５０間のピッチ（離間距離）とを調整することにより、線状のイメージをより確実に維持することができる。なお、第１模様４の凸部４０間のピッチの平均値を第２模様５の第１塗膜５０間のピッチの平均値に一致させるか、又はそれら平均値の差を所定値以下とすることで、第１及び第２模様４，５が重ねられた時により良好なイメージが得られる。 On the other hand, since both the first and second patterns 4 and 5 are linear patterns extending in the eaves building direction 3, even if the first and second patterns 4 and 5 are overlapped, a linear image is obtained. Be maintained. By adjusting the pitch (separation distance) between the convex portions 40 of the first pattern 4 and the pitch (separation distance) between the first coating films 50 of the second pattern 5, a linear image is more reliably maintained. be able to. The average value of the pitches between the convex portions 40 of the first pattern 4 is made to match the average value of the pitches between the first coating films 50 of the second pattern 5, or the difference between the average values is set to a predetermined value or less. As a result, a better image can be obtained when the first and second patterns 4 and 5 are superimposed.

なお、凸部４０及び第１塗膜５０の配置パターンの違いにより、第１及び第２模様４，５が互いに非同期で化粧面１３に設けられるように説明しているが、第１及び第２模様４，５を個々に見た時に凸部４０の配置パターンが第１模様５０の塗膜の配置パターンと同じであっても、第１及び第２模様４，５を軒方向２にずらして配置することにより、第１及び第２模様４，５を互いに非同期で化粧面１３に設けることができる。すなわち、凸部４０及び第１塗膜５０の配置パターンが必ずしも異なっている必要は無い。 Although it is explained that the first and second patterns 4 and 5 are provided on the decorative surface 13 asynchronously with each other due to the difference in the arrangement pattern of the convex portion 40 and the first coating film 50, the first and second patterns are provided. Even if the arrangement pattern of the convex portions 40 is the same as the arrangement pattern of the coating film of the first pattern 50 when the patterns 4 and 5 are viewed individually, the first and second patterns 4 and 5 are shifted in the eaves direction 2. By arranging them, the first and second patterns 4 and 5 can be provided on the decorative surface 13 asynchronously with each other. That is, the arrangement patterns of the convex portion 40 and the first coating film 50 do not necessarily have to be different.

このような外装材１では、凹凸により表された第１模様４と塗膜により表された第２模様５とが互いに非同期で設けられているので、第１模様４に制限されずに第２模様５により数多くの意匠を表現することができる。これにより、意匠の多様性をより容易に確保することができる。この構成は、化粧面の加工が容易な金属屋根材に特に有用である。特に金属屋根材においては、平滑な金属板に第２模様５を凸版印刷、平版印刷、凹版印刷及びインクジェット印刷などにより印刷した後、いわゆるプレコート方式で、エンボスロール加工やプレス成形により凹凸により表された第１模様４を形成することができる。このプレコート方式により所望の非同調の意匠をより確実に発現できる。 In such an exterior material 1, since the first pattern 4 represented by the unevenness and the second pattern 5 represented by the coating film are provided asynchronously with each other, the second pattern 4 is not limited to the first pattern 4. Many designs can be expressed by the pattern 5. As a result, the diversity of designs can be secured more easily. This configuration is particularly useful for metal roofing materials where the decorative surface is easy to process. In particular, in the case of metal roofing materials, the second pattern 5 is printed on a smooth metal plate by letterpress printing, flat plate printing, intaglio printing, inkjet printing, etc., and then expressed by embossing roll processing or press molding by the so-called precoating method. The first pattern 4 can be formed. By this precoat method, a desired non-synchronized design can be more reliably expressed.

実施の形態２．
図７は、本発明の実施の形態２による外装材１の化粧面１３に設けられる第３模様６の例を示す説明図である。第３模様６は、第２模様５とは異なる色調の塗膜により表された軒棟方向に延在する線状の模様である。具体的には、第３模様６は、軒棟方向３に線状に延在する第２模様５とは異なる色調の複数の第２塗膜６０によって構成されている。異なる色調とは、上述の色差ΔＥが１０よりも大きい色と定義することができる。第３模様６の第２塗膜６０の配置パターンは、第１模様４の凸部４０の配置パターン及び第２模様４の第１塗膜５０の配置パターンと異なっている。凸版印刷、平版印刷、凹版印刷及びインクジェット印刷を含む印刷機による印刷を表基材１２又はその素材金属板に施すことにより、化粧面１３に第３模様６を設けることができる。 Embodiment 2.
FIG. 7 is an explanatory view showing an example of a third pattern 6 provided on the decorative surface 13 of the exterior material 1 according to the second embodiment of the present invention. The third pattern 6 is a linear pattern extending in the eaves direction represented by a coating film having a color tone different from that of the second pattern 5. Specifically, the third pattern 6 is composed of a plurality of second coating films 60 having a color tone different from that of the second pattern 5 extending linearly in the eaves building direction 3. Different color tones can be defined as colors having the above-mentioned color difference ΔE larger than 10.
