以下、本発明を実施するための形態を説明する。 Hereinafter, modes for carrying out the present invention will be described.
本実施の形態の建築板１０は、図１のように、基板２０の表面の全面にわたって、複数の柄部３０を設けて形成されている。柄部３０は、例えば、折り紙をモチーフにして形成されるものである。これにより、建築板１０に対する陽光の当たり方に変化がつき、多彩で繊細な質感を表現することができる。 As shown in FIG. 1, the building board 10 of the present embodiment is formed by providing a plurality of handle portions 30 over the entire surface of the substrate 20. The handle 30 is formed using, for example, origami as a motif. As a result, the way the sunlight strikes the building board 10 changes, and a colorful and delicate texture can be expressed.
基板２０はいわゆる窯業系基板であって、セメント、パルプ、骨材、水などを含有するセメント組成物の硬化物である。基板２０は抄造法や押出成形法などで形成される。基板２０は正面視で矩形に形成されている。基板２０の長手端部には、相じゃくり等で接合するための実部が形成されていてもよい。なお、基材は窯業系基板に限られるものではなく、金属系、樹脂系であってもよく、また、外装材、内装材、屋根材などに用いるものが考えられる。 The substrate 20 is a so-called ceramic substrate and is a cured product of a cement composition containing cement, pulp, aggregate, water and the like. The substrate 20 is formed by a papermaking method or an extrusion method. The board | substrate 20 is formed in the rectangle by front view. A real part for joining by phase burr or the like may be formed at the longitudinal end of the substrate 20. The base material is not limited to a ceramic substrate, and may be a metal or resin material, and those used for exterior materials, interior materials, roof materials, and the like are conceivable.
柄部３０は正面視において短冊状に形成されている。複数の柄部３０は基板２０の長手方向の全長にわたって並ぶように形成されている。複数の柄部３０は基板２０の短手方向の全長にわたって並ぶように形成されている。本明細書において、「全長」とは厳密な意味での全長だけでなく、ほぼ全長である場合も含む。正面視における柄部３０の長手方向は基板２０の短手方向と平行となるように形成されている。正面視における柄部３０の短手方向は基板２０の長手方向と平行となるように形成されている。本明細書において、「平行」とは厳密な意味での平行だけでなく、ほぼ平行である場合も含む。全部の柄部３０の長手方向の寸法は一定に形成されている。本明細書において、「一定」とは厳密な意味での一定だけでなく、ほぼ一定であればよい。正面視における柄部３０の長手方向の寸法は、例えば、３．０〜９０．０ｍｍに形成されている。正面視における柄部３０の短手方向の寸法は一定ではなく、例えば、２０．０〜３００．０ｍｍの範囲で適宜に形成されている。柄部３０は、例えば、硬化前の基板２０の表面に成形型をプレスして形成される。 The handle 30 is formed in a strip shape when viewed from the front. The plurality of handle portions 30 are formed so as to be arranged over the entire length of the substrate 20 in the longitudinal direction. The plurality of handle portions 30 are formed so as to be arranged over the entire length of the substrate 20 in the short direction. In the present specification, the “full length” includes not only the full length in a strict sense but also the case where it is almost the full length. The longitudinal direction of the handle 30 in front view is formed to be parallel to the short direction of the substrate 20. The short side direction of the handle 30 in front view is formed to be parallel to the long direction of the substrate 20. In this specification, the term “parallel” includes not only parallel in a strict sense but also a case of being substantially parallel. All the handle portions 30 are formed with a constant longitudinal dimension. In the present specification, “constant” is not limited to being strictly constant, but may be substantially constant. The longitudinal dimension of the handle 30 in front view is, for example, 3.0 to 90.0 mm. The dimension in the short direction of the handle 30 in front view is not constant, and is appropriately formed in the range of 20.0 to 300.0 mm, for example. The handle 30 is formed, for example, by pressing a mold on the surface of the substrate 20 before curing.
柄部３０の表面は凹凸に形成されており、これにより凹凸柄３１が形成されている。凹凸柄３１は不規則な形状である。すなわち、凹凸柄３１は規則正しい形状ではなく、不定形であって、様々な形状や厚み寸法に形成されている。このような凹凸柄３１により柄部３０は石やタイルやレンガのような外観に形成される。凹凸柄３１には形状の異なる複数種のものがあり、隣り合う柄部３０の凹凸柄３１の種類は互いに異なっていることが好ましい。凹凸柄３１の深さ寸法は一定ではなく、例えば、０．５〜７．０ｍｍの範囲で適宜に形成されている。 The surface of the handle portion 30 is formed with unevenness, whereby an uneven pattern 31 is formed. The uneven pattern 31 has an irregular shape. That is, the concavo-convex pattern 31 is not a regular shape but an indefinite shape, and is formed in various shapes and thickness dimensions. The pattern portion 30 is formed in such an appearance as a stone, a tile, or a brick by such an uneven pattern 31. There are a plurality of types of concavo-convex patterns 31 having different shapes, and the types of concavo-convex patterns 31 of adjacent pattern portions 30 are preferably different from each other. The depth dimension of the concavo-convex pattern 31 is not constant, and is appropriately formed, for example, in the range of 0.5 to 7.0 mm.
図２（ａ）及び（ｂ）のように、基板２０の長手方向において隣り合う柄部３０は、その長手端部同士が全長にわたって接合されている（突きつけられている）。また基板２０の長手方向において隣り合う柄部３０は、その表面の傾斜角度Ｋ１、Ｋ２が互いに異なって形成されている。この場合、柄部３０の表面の傾斜角度Ｋ１、Ｋ２は、図３のように、基板２０の平坦な裏面（柄部３０が形成された表面と反対側の面）２１に対する垂線Ｐを想定し、隣り合う柄部３０の正面視における境界線Ｍを通る垂線Ｐと、この垂線Ｐに隣接する柄部３０の表面との間の角度で規定される。このように隣り合う柄部３０の表面の傾斜角度Ｋ１、Ｋ２が互いに異なって形成されているので、各柄部３０が自然な石のような外観に形成することができる。図２（ａ）及び（ｂ）は、基板２０を長手方向と平行な方向に切断した場合の断面図であって、図２（ａ）と図２（ｂ）は切断位置が異なる。 As shown in FIGS. 2A and 2B, the longitudinal end portions of the handle portions 30 adjacent in the longitudinal direction of the substrate 20 are joined (abutted) over the entire length. Further, the pattern portions 30 adjacent in the longitudinal direction of the substrate 20 are formed so that their surface inclination angles K1 and K2 are different from each other. In this case, the inclination angles K1 and K2 of the surface of the handle 30 are assumed to be perpendicular P to the flat back surface (surface opposite to the surface on which the handle 30 is formed) 21 of the substrate 20, as shown in FIG. The angle between the perpendicular P passing through the boundary line M in the front view of the adjacent handle 30 and the surface of the handle 30 adjacent to the perpendicular P is defined. Thus, since the inclination angles K1 and K2 of the surfaces of the adjacent handle portions 30 are different from each other, each handle portion 30 can be formed in a natural stone-like appearance. 2A and 2B are cross-sectional views when the substrate 20 is cut in a direction parallel to the longitudinal direction, and FIG. 2A and FIG. 2B are different in cutting position.
隣り合う柄部３０の長手端部同士の接合部分には区切り部４０が形成されている。図４のように、隣り合う柄部３０において、一方の柄部３０１の長手端部の長辺３０２と他方の柄部３０３の長辺端部の長辺３０４とは全長にわたって完全に一致するものではなく、長辺３０２と長辺３０４とは一部又は全部が互いに上記垂線と平行な方向（基板２０の厚み方向）で位置ずれしている。すなわち、隣り合う柄部３０において、一方の柄部３０１の長手端部の形状と、他方の柄部３０３の長手端部の形状とが互いに異なっており、特に、一方の柄部３０の長手端部の厚みと、他方の長手端部の厚みとが互いに異なっているので、長辺３０２と長辺３０４とは一部又は全部が互いに上記垂線と平行な方向で位置ずれしている。従って、長辺３０２が長辺３０４よりも接合部分の表面に突出している場合は、柄部３０１の長手端部が長辺３０４よりも表面側に突出し、柄部３０１の長手端面が露出している。逆に、長辺３０４が長辺３０２よりも接合部分の表面に突出している場合は、柄部３０３の長手端部が長辺３０２よりも表面側に突出し、柄部３０３の長手端面が露出している。このように柄部３０１の長手端部が長辺３０４よりも表面側に突出している部分と、柄部３０３の長手端部が長辺３０２よりも表面側に突出している部分とが区切り部４０として形成されている。長辺３０２と長辺３０４とが全長にわたって位置ずれしている場合は、隣り合う柄部３０１，３０３の長手端部同士の接合部分の全長にわたって区切り部４０が形成される。長辺３０２と長辺３０４とが部分的に位置ずれしている場合は、隣り合う柄部３０１，３０３の長手端部同士の接合部分の全長に沿って、複数の区切り部４０が断続的に形成される。このように隣り合う柄部３０１，３０３の長手端部同士は、その少なくとも一部が基板２０の厚み方向で互いに位置ずれすることにより、区切り部４０が形成される。 A delimiter 40 is formed at a joint portion between the longitudinal ends of the adjacent handle portions 30. As shown in FIG. 4, in the adjacent handle portions 30, the long side 302 of the long end portion of one handle portion 301 and the long side 304 of the long side end portion of the other handle portion 303 completely coincide with each other over the entire length. Instead, the long side 302 and the long side 304 are partially or completely displaced from each other in the direction parallel to the perpendicular (thickness direction of the substrate 20). That is, in the adjacent handle portion 30, the shape of the longitudinal end portion of one handle portion 301 and the shape of the longitudinal end portion of the other handle portion 303 are different from each other. Since the thickness of the portion and the thickness of the other longitudinal end portion are different from each other, the long side 302 and the long side 304 are partially or completely displaced from each other in a direction parallel to the perpendicular. Therefore, when the long side 302 protrudes from the long side 304 to the surface of the joint portion, the longitudinal end portion of the handle 301 protrudes to the surface side from the long side 304, and the longitudinal end surface of the handle 301 is exposed. Yes. On the contrary, when the long side 304 protrudes from the long side 302 to the surface of the joint portion, the longitudinal end portion of the handle 303 protrudes to the surface side from the long side 302 and the longitudinal end surface of the handle 303 is exposed. ing. In this way, the part where the long end of the handle 301 protrudes on the surface side from the long side 304 and the part where the long end of the handle 303 protrudes on the surface side of the long side 302 are separated from each other. It is formed as. When the long side 302 and the long side 304 are displaced over the entire length, the delimiter 40 is formed over the entire length of the joint portion between the longitudinal ends of the adjacent handle portions 301 and 303. When the long side 302 and the long side 304 are partially misaligned, the plurality of partitioning portions 40 are intermittently formed along the entire length of the joint portion between the longitudinal ends of the adjacent handle portions 301 and 303. It is formed. As described above, at least a part of the longitudinal end portions of the adjacent pattern portions 301 and 303 is displaced from each other in the thickness direction of the substrate 20, so that the partition portion 40 is formed.
図５のように、区切り部４０の厚み寸法Ｈは、凹凸柄３１の深さ寸法Ｄと同等であるか、あるいは凹凸柄３１の深さ寸法よりも小さく形成されている。ここで、区切り部４０の厚み寸法Ｈとは、隣り合う柄部３０の境界線Ｍから区切り部４０の先端までの寸法である。区切り部４０は一定の厚み寸法Ｈではない場合は、最も厚み寸法Ｈが大きい部分が、凹凸柄３１の深さ寸法Ｄと同等あるいは凹凸柄３１の深さ寸法Ｄよりも小さく形成される。また凹凸柄３１の深さ寸法Ｄは、その区切り部４０を形成している柄部３０に形成される凹凸柄３１であって、最も凹んだ凹部分（凹柄３１１）の底面と最も突出した凸部分（凸柄３１２）の先端との間の寸法である。 As shown in FIG. 5, the thickness dimension H of the separator 40 is equal to the depth dimension D of the concave / convex pattern 31 or smaller than the depth dimension of the concave / convex pattern 31. Here, the thickness dimension H of the separator 40 is a dimension from the boundary line M of the adjacent handle 30 to the tip of the separator 40. When the delimiter 40 does not have a constant thickness dimension H, the portion having the largest thickness dimension H is formed to be equal to or smaller than the depth dimension D of the uneven pattern 31. Further, the depth dimension D of the concave / convex pattern 31 is the concave / convex pattern 31 formed on the handle portion 30 forming the partitioning portion 40, and protrudes most from the bottom surface of the concave portion (the concave handle 311). It is a dimension between the front-end | tips of a convex part (convex pattern 312).
そして、上記のような区切り部４０を形成することによって、基板２０の長手方向において、複数の柄部３０が不規則に並んで形成されることになり、自然でリアリティのある石積み調外観を形成しやすいものである。 Then, by forming the partitioning portion 40 as described above, a plurality of handle portions 30 are irregularly arranged in the longitudinal direction of the substrate 20 to form a natural and realistic masonry-like appearance. It is easy to do.
図６のように、基板２０の長手方向において隣り合う柄部３０の長手端部同士の接合部分には、区切り溝５０が形成されていることが好ましい。特に、基板２０の長手方向において隣り合う柄部３０の表面の傾斜角度Ｋ１、Ｋ２の差が小さい場合（傾斜角度の差が０〜７０°（０°を含まず））又は区切り部４０の厚み寸法Ｈが小さい場合（厚み寸法が０〜７．０ｍｍ（０ｍｍを含まず））には、区切り溝５０を設けるのが好ましい。区切り溝５０は、基板２０の長手方向において隣り合う柄部３０の長手端部同士の接合部分の境界線Ｍに沿って形成されるものである。区切り溝５０は、境界線Ｍの全長にわたって連続的に設けても良いし、境界線Ｍの全長にわたって断続的に設けても良い。区切り溝５０の幅寸法は０．３〜５．０ｍｍに形成することができる。この幅寸法の範囲で区切り溝５０を形成すると、区切り溝５０が極端に目立つことがなく、自然な石積み調が損なわれにくくなる。また区切り溝５０の深さ寸法は０．３〜３．０ｍｍに形成することができる。この深さ寸法の範囲で区切り溝５０を形成すると、区切り溝５０が極端に目立つことがなく、自然な石積み調が損なわれにくくなる。 As shown in FIG. 6, it is preferable that a separation groove 50 is formed at a joint portion between the longitudinal ends of the handle portions 30 adjacent in the longitudinal direction of the substrate 20. In particular, when the difference between the inclination angles K1 and K2 of the surface of the handle portion 30 adjacent in the longitudinal direction of the substrate 20 is small (the difference between the inclination angles is 0 to 70 ° (not including 0 °)), or the thickness of the separation portion 40 When the dimension H is small (thickness dimension is 0 to 7.0 mm (excluding 0 mm)), it is preferable to provide the separation groove 50. The partition groove 50 is formed along the boundary line M of the joint portion between the longitudinal ends of the handle portions 30 adjacent in the longitudinal direction of the substrate 20. The separation groove 50 may be provided continuously over the entire length of the boundary line M, or may be provided intermittently over the entire length of the boundary line M. The width dimension of the separation groove 50 can be formed to 0.3 to 5.0 mm. If the dividing groove 50 is formed in the range of the width dimension, the dividing groove 50 does not become extremely conspicuous, and the natural masonry tone is hardly impaired. Moreover, the depth dimension of the division | segmentation groove | channel 50 can be formed in 0.3-3.0 mm. If the dividing groove 50 is formed within the range of the depth dimension, the dividing groove 50 does not become extremely conspicuous and the natural masonry tone is hardly impaired.
図７のように、基板２０の短手方向において隣り合う柄部３０の短手端部の間には、目地状溝６０が形成されていることが好ましい。目地状溝６０は基板２０の長手方向の全長にわたって連続して設けられている。目地状溝６０は区切り部４０の最下位置（境界線Ｍの位置）よりも深く形成されている。すなわち、目地状溝６０の底面６１は区切り部４０の最下位置（境界線Ｍの位置）よりも深い位置に形成されている。これにより、自然でリアリティのある石積み調が強調されることになる。目地状溝６０の深さ寸法は、特に限定されないが、２．０〜７．０ｍｍであることが好ましい。 As shown in FIG. 7, it is preferable that joint grooves 60 are formed between the short ends of the pattern portions 30 adjacent in the short direction of the substrate 20. The joint grooves 60 are continuously provided over the entire length of the substrate 20 in the longitudinal direction. The joint groove 60 is formed deeper than the lowest position (position of the boundary line M) of the partition 40. That is, the bottom surface 61 of the joint groove 60 is formed at a position deeper than the lowest position (position of the boundary line M) of the partition 40. This emphasizes natural and realistic masonry. The depth dimension of the joint groove 60 is not particularly limited, but is preferably 2.0 to 7.0 mm.
上記のような建築板１０において、複数の柄部３０により断面台形状の台形凸部３２を形成し、他の複数の柄部３０により断面山形状の山形凸部３３を形成し、複数の台形凸部３２と複数の山形凸部３３とを基板２０の表面に不規則に配置して形成するのが好ましい。これにより、自然でリアリティのある石積み調が強調されることになる。例えば、図８のものは、３つの柄部３２０、３２１、３２２で台形凸部３２が形成されている。また、２つの柄部３３０、３３１で山形凸部３３が形成されている。 In the building board 10 as described above, a trapezoidal convex part 32 having a trapezoidal cross section is formed by a plurality of handle parts 30, and a mountain-shaped convex part 33 having a cross-sectional mountain shape is formed by another plurality of handle parts 30. It is preferable to form the convex portions 32 and the plurality of mountain-shaped convex portions 33 by irregularly arranging them on the surface of the substrate 20. This emphasizes natural and realistic masonry. For example, in FIG. 8, the trapezoidal convex portion 32 is formed by three handle portions 320, 321, and 322. Further, an angled convex portion 33 is formed by the two handle portions 330 and 331.
