Description

本発明は、建築板とその製造方法に関するものである。 The present invention relates to a building board and a method for manufacturing the same.

従来から、窯業系サイディングボードや金属系サイディングボードなどが建築物の外壁や内壁を構成する建築板として用いられている。建築板は通常、長方形状の長板であり、複数の建築板を貼り合わせて建築物の外壁や内壁が構成される。 Conventionally, ceramic siding boards and metal siding boards have been used as building boards constituting the outer and inner walls of buildings. A building board is usually a rectangular long board, and a plurality of building boards are laminated to form an outer wall or an inner wall of a building.

その際に、建築物の隅部には出隅(出隅用パネル)と呼ばれる断面L字形状の部材を貼ることが一般におこなわれている。この出隅用パネルは、壁面の外観に統一感をもたせるべく、特許文献1に記載されるように、建築板を縦方向に切断して製造されることが多い。 At that time, it is common practice to attach a member having an L-shaped cross section called a protruding corner (projecting corner panel) to the corner of the building. This protruding corner panel is often manufactured by cutting a building board in the vertical direction as described in Patent Document 1 in order to give a unified appearance to the wall surface.

ところで、建築板の表面には意匠性を高める目的で様々な凹凸形状が設けられることが多く、例えば特許文献2には、表面に縦・横の目地(溝)で区切られる複数のブロック柄(凸ブロック)を有する建築板が開示されている。 By the way, the surface of a building board is often provided with various uneven shapes for the purpose of enhancing the design. For example, in Patent Document 2, a plurality of block patterns (grooves) are divided on the surface by vertical and horizontal joints (grooves). A building board having a convex block) is disclosed.

特開2000−234431号公報Japanese Unexamined Patent Publication No. 2000-234431 特開2005−177578号公報Japanese Unexamined Patent Publication No. 2005-177578

例えば特許文献2で開示されるような建築板を縦方向に切断して出隅用パネルを製造する場合、切断位置によってはブロック柄の横幅が極端に狭くなる部位が生じ得る。このように横幅が極端に狭いブロック柄は、横幅が狭い状態で***していることから、製造や運搬、保管の際に***している部分が欠け易く、損傷する可能性があるといった課題を有している。 For example, when a building board as disclosed in Patent Document 2 is cut in the vertical direction to manufacture a panel for a protruding corner, a portion where the width of the block handle becomes extremely narrow may occur depending on the cutting position. Since the block handle with an extremely narrow width is raised in a narrow width state, the raised part is likely to be chipped during manufacturing, transportation, and storage, and there is a possibility of damage. Have.

以上のことより、表面に縦・横の目地(溝)で区切られる複数のブロック柄を有する建築板を縦方向に切断して出隅用パネルを製造するに当たっては、横幅が極端に狭いブロック柄ができないように切断位置を考慮し、決定している。そのため、建築板の切断に手間がかかるとともに、往々にして余分な端材が発生するといった課題がある。 Based on the above, when manufacturing a panel for outside corners by cutting a building board having a plurality of block patterns separated by vertical and horizontal joints (grooves) on the surface in the vertical direction, the block pattern has an extremely narrow width. It is decided by considering the cutting position so that it cannot be done. Therefore, it takes time and effort to cut the building board, and there is a problem that extra scraps are often generated.

本発明は上記する問題に鑑みてなされたものであり、出隅用パネルを製造するために建築板が切断される際に横幅が極端に狭いブロック柄が発生し難く、意匠性に優れた建築板とその製造方法を提供することを目的としている。 The present invention has been made in view of the above problems, and when a building board is cut to manufacture a panel for a protruding corner, a block pattern having an extremely narrow width is unlikely to occur, and the building is excellent in design. It is an object of the present invention to provide a board and a method for manufacturing the board.

前記目的を達成すべく、本発明の第一の態様による建材板は、複数の第一凹部を有する第一領域と、前記第一領域と隣接し、複数の第二凹部を有する第二領域と、を備えた基材を具備し、前記第一領域の複数の前記第一凹部の平均深さは、前記第二領域の複数の前記第二凹部の平均深さよりも深く、少なくとも前記第一領域の基材の表面の一部には第一塗膜が形成されており、前記基材の表面は、前記第一領域よりも前記第二領域で多く露出しているものである。 In order to achieve the above object, the building material board according to the first aspect of the present invention has a first region having a plurality of first recesses and a second region adjacent to the first region and having a plurality of second recesses. , The average depth of the plurality of first recesses in the first region is deeper than the average depth of the plurality of second recesses in the second region, and at least the first region. A first coating film is formed on a part of the surface of the base material, and the surface of the base material is exposed more in the second region than in the first region.

ここで、「複数の第一凹部の平均深さ」、「複数の第二凹部の平均深さ」とは、第一領域と第二領域のそれぞれにおいて、各領域内の各凹部の深さから第一凹部の平均値と第二凹部の平均値を算定し、各凹部の平均深さとしたものである。第一凹部と第二凹部の平均深さは設計データから算出することができる。設計データが無い場合には、例えば各領域内の凹部の深さをマイクロスコープ、デプスゲージ等で測定し、算出することができる。 Here, the "average depth of the plurality of first recesses" and the "average depth of the plurality of second recesses" are defined from the depth of each recess in each region in each of the first region and the second region. The average value of the first recess and the average value of the second recess were calculated and used as the average depth of each recess. The average depth of the first recess and the second recess can be calculated from the design data. When there is no design data, for example, the depth of the recess in each region can be measured and calculated with a microscope, a depth gauge, or the like.

また、「少なくとも第一領域の表面の一部には第一塗膜が形成されており」とは、第一領域の表面の一部にのみ第一塗膜が形成される形態の他、第二領域の表面の一部にも第一塗膜が形成される形態を含む意味である。 In addition, "the first coating film is formed on at least a part of the surface of the first region" means that the first coating film is formed only on a part of the surface of the first region, and the first It means that the first coating film is also formed on a part of the surface of the two regions.

また、「基材の表面は、第一領域よりも第二領域で多く露出している」とは、第一領域の表面と第二領域の表面は、ともに基材の表面が露出している部分を含み、第二領域における基材の表面が露出した部分の面積は、第一領域における基材の表面が露出した部分の面積よりも広いことを意味する。 In addition, "the surface of the base material is more exposed in the second region than in the first region" means that the surface of the base material is exposed on both the surface of the first region and the surface of the second region. It means that the area of the portion including the portion where the surface of the base material is exposed in the second region is larger than the area of the portion where the surface of the base material is exposed in the first region.

本発明の第一の態様による建築板は、第一領域と第二領域の凹部の平均深さの違いにより、第一塗膜による各領域の被覆状態と基材の表面の露出状態が異なるので、第一領域と第二領域の外観が異なる。外観が異なる第一領域と第二領域が隣接しているので、第一領域と第二領域の境界が表現される。この境界により、この建築板は、縦目地を用いなくても複数種の柄模様を表現することができ、意匠性に優れた建築板となる。 In the building board according to the first aspect of the present invention, the covering state of each region by the first coating film and the exposed state of the surface of the base material differ due to the difference in the average depth of the recesses in the first region and the second region. , The appearance of the first area and the second area are different. Since the first region and the second region having different appearances are adjacent to each other, the boundary between the first region and the second region is expressed. Due to this boundary, this building board can express a plurality of types of patterns without using vertical joints, and becomes a building board with excellent design.

さらに、この建築板は縦目地を用いずに柄模様を表現することができるので、縦方向であればどの部位で切断しても、縦目地による極端に横幅の狭い***部が形成されることがない。そのため、建築板の切断に際して余分な端材が発生するといった課題も解消され、建築板を用いた出隅用パネルの効率的な製造を実現できる。また、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 Furthermore, since this building board can express a pattern without using vertical joints, an extremely narrow ridge is formed by the vertical joints regardless of where the cut is made in the vertical direction. There is no. Therefore, the problem that extra scraps are generated when cutting the building board is solved, and it is possible to efficiently manufacture the protruding corner panel using the building board. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

また、本発明の第二の態様による建築板は、前記基材の表面は第二塗膜によって形成されているものである。 Further, in the building board according to the second aspect of the present invention, the surface of the base material is formed by the second coating film.

本発明の第二の態様によれば、例えば第二塗膜の色を第一塗膜と異ならせると、第二領域の表面には第二塗膜が露出しているので、第一領域と第二領域の外観が大きく異なる。そして、第一領域と第二領域は隣接しているものの外観が大きく異なるので、第一領域と第二領域の境界は一層明確となり、目地を用いなくても複数種の柄模様を有する、意匠性に優れた建築板となる。 According to the second aspect of the present invention, for example, when the color of the second coating film is different from that of the first coating film, the second coating film is exposed on the surface of the second region. The appearance of the second area is very different. Since the first region and the second region are adjacent to each other but the appearances are significantly different, the boundary between the first region and the second region becomes clearer, and the design has a plurality of types of patterns without using joints. It will be a building board with excellent properties.

また、本発明の第三の態様による建築板は、前記第一塗膜の色と前記基材の表面の色が異なっているものである。 Further, in the building board according to the third aspect of the present invention, the color of the first coating film and the color of the surface of the base material are different.

第一塗膜と基材の表面の色が異なる実施の形態には大きく以下で示す二種類の形態がある。 There are roughly two types of embodiments shown below in the embodiments in which the colors of the surfaces of the first coating film and the base material are different.

一つ目の形態は、基材の表面に、第一塗膜と色が異なる第二塗膜が形成されているものである。 In the first form, a second coating film having a color different from that of the first coating film is formed on the surface of the base material.

一方、二つ目の形態は、基材の表面には塗膜が形成されておらず、基材自体が第一塗膜とは異なる色で着色しているものである。 On the other hand, in the second form, no coating film is formed on the surface of the base material, and the base material itself is colored with a color different from that of the first coating film.

本発明の第三の態様によれば、第一領域の表面の一部に第一塗膜が形成されており、第二領域の表面には第一塗膜と色の異なる基材の表面が露出しているので、第一領域と第二領域の外観が更に大きく異なる。そして、第一領域と第二領域の境界は更に明確となり、縦目地を用いなくても複数種の柄模様を有する、意匠性に優れた建築板となる。 According to the third aspect of the present invention, the first coating film is formed on a part of the surface of the first region, and the surface of the base material having a color different from that of the first coating film is formed on the surface of the second region. Since it is exposed, the appearances of the first region and the second region are further significantly different. Then, the boundary between the first region and the second region becomes clearer, and the building board has a plurality of types of patterns without using vertical joints and has excellent design.

また、本発明の第四の態様による建築板は、前記第一領域と前記第二領域がともに平面視において矩形を呈しているものである。 Further, in the building board according to the fourth aspect of the present invention, both the first region and the second region have a rectangular shape in a plan view.

ここで、「平面視において矩形」とは、平面視が長方形の他にも正方形も含む意味であり、いわゆるブロック調の外観を表現することができる。 Here, "rectangular in plan view" means that the plan view includes a square as well as a rectangle, and a so-called block-like appearance can be expressed.

本発明の第四の態様によれば、凹部の平均深さと基材の露出状態が異なり、場合によってはさらに第一塗膜と基材表面の色も異なっているブロック調の複数の第一領域と第二領域が並んで構成されることから、目地を用いていないにもかかわらず、ブロック調を表現できる。さらに、この建築板は目地を用いずに柄模様を表現しているので、出隅用パネルの効率的な製造を実現できる。また、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 According to the fourth aspect of the present invention, a plurality of block-like first regions in which the average depth of the recesses and the exposed state of the base material are different, and in some cases, the colors of the first coating film and the surface of the base material are also different. Since the second region is composed side by side, it is possible to express a block tone even though no joints are used. Furthermore, since this building board expresses a pattern without using joints, it is possible to efficiently manufacture a panel for a protruding corner. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

また、本発明の第五の態様による建築板は、前記第一凹部と前記第二凹部が同一方向に延びているものである。 Further, in the building board according to the fifth aspect of the present invention, the first recess and the second recess extend in the same direction.

例えば、横長(水平方向に長い)の建築板において、この水平方向に第一領域の第一凹部と第二領域の第二凹部が延びている形態が挙げられる。 For example, in a horizontally long (horizontally long) building board, there is a form in which the first recess of the first region and the second recess of the second region extend in the horizontal direction.

なお、「同一方向に延びている」とは、建築板を大局的に見た際に一定の同じ方向に延びていることを意味しており、建築板に近づいて微視的に見た際に第一凹部、第二凹部ともに多少蛇行しているようなものも、この同一方向に延びている概念に包含される。 In addition, "extending in the same direction" means that the building board extends in the same direction when viewed from a broad perspective, and when the building board is approached and viewed microscopically. The concept that both the first recess and the second recess are slightly meandering is also included in this concept of extending in the same direction.

本発明の第五の態様によれば、第一領域の複数の第一凹部と第二領域の複数の第二凹部が同一方向に延びていることにより、見た目の統一感が図られ、意匠性に優れた建築板となる。 According to the fifth aspect of the present invention, the plurality of first recesses in the first region and the plurality of second recesses in the second region extend in the same direction, thereby achieving a unified appearance and design. It becomes an excellent building board.

また、第一領域の複数の第一凹部と第二領域の複数の第二凹部が同一方向に延びていることにより、例えば塗料を掻き取る塗装(ワイピング塗装、掻き取り塗装)における掻き取り工程において、掻き取り装置の掻き取り部を第一凹部と第二凹部内に入り込ませて、円滑に塗料を掻き取ることができる。 Further, since the plurality of first recesses in the first region and the plurality of second recesses in the second region extend in the same direction, for example, in a scraping step in coating for scraping paint (wiping coating, scraping coating). , The scraping portion of the scraping device can be inserted into the first recess and the second recess to smoothly scrape the paint.

また、本発明の第六の態様による建築板は、前記第一領域と前記第二領域に接する横溝を備えているものである。 Further, the building board according to the sixth aspect of the present invention is provided with a lateral groove in contact with the first region and the second region.

本発明の第六の態様によれば、横方向に並ぶ第一領域および第二領域から構成される各段に横溝が接し、横溝によって上下の段を区画するものである。横目地は横溝によって表現されており、縦目地は第一領域と第二領域のコントラストによって表現されている。 According to the sixth aspect of the present invention, the horizontal groove is in contact with each step composed of the first region and the second region arranged in the horizontal direction, and the upper and lower steps are divided by the horizontal groove. The horizontal joints are represented by horizontal grooves, and the vertical joints are represented by the contrast between the first region and the second region.

本発明の第六態様によれば、第一領域と第二領域の境界の一部が横目地に相当する横溝によって明確に表現でき、縦目地は第一領域と第二領域の塗膜の差で表現できるので、意匠性に優れた建築板となる。 According to the sixth aspect of the present invention, a part of the boundary between the first region and the second region can be clearly expressed by the horizontal groove corresponding to the horizontal joint, and the vertical joint is the difference between the coating films in the first region and the second region. Because it can be expressed with, it becomes a building board with excellent design.

本発明の第七の態様による建築板は、横溝の上下で第一領域と第二領域が隣接している形態、言い換えれば、第一領域と第二領域が横溝を挟んで上下に隣接しているものである。 The building board according to the seventh aspect of the present invention has a form in which the first region and the second region are adjacent to each other above and below the lateral groove, in other words, the first region and the second region are vertically adjacent to each other with the lateral groove in between. It is something that is.

本発明の第七の態様によれば、横目地としての横溝によって第一領域と第二領域の上下の境界が明確となり、縦目地は第一領域と第二領域の塗膜の差で表現されるので、意匠性に優れた建築板となる。また、この建築板は縦目地を用いずに柄模様を表現しているので、出隅用パネルの効率的な製造を実現できる。更に、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 According to the seventh aspect of the present invention, the horizontal groove as the horizontal joint makes the upper and lower boundaries between the first region and the second region clear, and the vertical joint is represented by the difference between the coating films in the first region and the second region. Therefore, it becomes a building board with excellent design. In addition, since this building board expresses a pattern without using vertical joints, it is possible to efficiently manufacture a panel for a protruding corner. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

また、本発明の第八の態様による建築板は、前記第一凹部と前記第二凹部がともに前記横溝の長手方向に沿って延びているものである。 Further, in the building board according to the eighth aspect of the present invention, both the first recess and the second recess extend along the longitudinal direction of the lateral groove.

本発明の第八の態様によれば、第一領域の複数の第一凹部と第二領域の複数の第二凹部が横溝の長手方向に延びていることにより、見た目の統一感が図られ、意匠性に優れた建築板となる。また、この建築板は縦目地を用いず、第一領域と第二領域のコントラストによって第一領域と第二領域の境界を表現しているので、出隅用パネルの効率的な製造を実現できる。更に、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 According to the eighth aspect of the present invention, the plurality of first recesses in the first region and the plurality of second recesses in the second region extend in the longitudinal direction of the lateral groove, thereby achieving a unified appearance. It will be a building board with excellent design. In addition, since this building board does not use vertical joints and expresses the boundary between the first region and the second region by the contrast between the first region and the second region, it is possible to realize efficient manufacturing of the projected corner panel. .. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

また、本発明の第九の態様による建築板は、前記建築板は長手方向を有する、平面視において長方形であり、前記横溝が前記建築板の長手方向に沿って延びているものである。 Further, in the building board according to the ninth aspect of the present invention, the building board has a longitudinal direction, is rectangular in a plan view, and the lateral groove extends along the longitudinal direction of the building board.

本発明の第九の態様によれば、建築板が平面視において長方形であり、第一、第二領域が例えば平面視矩形を呈し、横溝が長方形の建築板の長手方向に延びていることにより、横溝に接する第一領域と第二領域は建築板の長手方向に配置されることになる。平面視矩形の第一領域と第二領域が建築板の長手方向に配列されていることから、見た目の統一感も図られる。また、長手方向には明確な横溝が延び、縦目地は第一領域と第二領域の塗膜の差によって表現されるので、意匠性に優れた建築板となる。 According to the ninth aspect of the present invention, the building board is rectangular in a plan view, the first and second regions are, for example, rectangular in a plan view, and the lateral groove extends in the longitudinal direction of the rectangular building board. , The first region and the second region in contact with the lateral groove will be arranged in the longitudinal direction of the building board. Since the first region and the second region of the plan view rectangle are arranged in the longitudinal direction of the building board, a sense of unity in appearance can be achieved. Further, a clear horizontal groove extends in the longitudinal direction, and the vertical joint is expressed by the difference between the coating films in the first region and the second region, so that the building board has excellent design.

また、建築板を縦方向(長方形の短辺方向に平行な方向)に切断して出隅用パネルを製作するに当たり、建築板には縦溝(縦目地)が存在せず、長手方向に延びる横溝のみが存在することから、切断位置によって出隅用パネルに極端に横幅の狭い***部が形成されることがない。そのため、出隅用パネルの効率的な製造を実現できる。更に、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 In addition, when cutting a building board in the vertical direction (direction parallel to the short side direction of a rectangle) to produce a panel for outside corners, the building board does not have vertical grooves (vertical joints) and extends in the longitudinal direction. Since only the lateral groove is present, an extremely narrow ridge is not formed on the protruding corner panel depending on the cutting position. Therefore, efficient manufacturing of the projected corner panel can be realized. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

また、本発明の第十の態様による建築板は、前記第一凹部間には第一凸部が形成され、前記第二凹部間には第二凸部が形成され、前記第一領域と前記第二領域はそれぞれ複数の前記第一凸部と複数の前記第二凸部を備えており、前記第一凸部と前記第二凸部の高さが同一のものである。 Further, in the building board according to the tenth aspect of the present invention, a first convex portion is formed between the first concave portions, a second convex portion is formed between the second concave portions, and the first region and the said The second region includes a plurality of the first convex portions and a plurality of the second convex portions, and the heights of the first convex portion and the second convex portion are the same.

ここで、「高さが同一」とは、ある基準からの高さが同じという意味であり、例えば建築板の裏面からの距離が同じことが挙げられる。 Here, "the same height" means that the height from a certain standard is the same, and for example, the distance from the back surface of the building board is the same.

本発明の第十の態様によれば、第一領域の複数の第一凸部と第二領域の複数の第二凸部の高さが同一であることにより、見た目の統一感が図られ、意匠性に優れた建築板となる。 According to the tenth aspect of the present invention, the heights of the plurality of first convex portions of the first region and the plurality of second convex portions of the second region are the same, so that a sense of unity in appearance can be achieved. It will be a building board with excellent design.

また、第一領域、第二領域ともに複数の凸部を備えていることで、例えば塗料を掻き取る塗装(ワイピング塗装、掻き取り塗装)における掻き取り工程において、掻き取り装置の掻き取り部を高さが同一の凸部を基準として凹部内に入り込ませて円滑に塗料を掻き取ることができる。 Further, since both the first region and the second region are provided with a plurality of convex portions, the scraping portion of the scraping device is raised in the scraping process in, for example, painting (wiping coating, scraping coating) for scraping paint. The paint can be smoothly scraped off by entering the concave portion with the same convex portion as a reference.

また、本発明の第十一の態様は建築板の製造方法であり、この製造方法は、複数の第一凹部を有する第一領域と、前記第一領域と隣接し、複数の第二凹部を有する第二領域と、を備え、前記第一領域の複数の第一凹部の平均深さは、前記第二領域の複数の第二凹部の平均深さよりも深い基材を準備する第一のステップと、前記第一領域と前記第二領域の表面に第一塗膜用塗料を塗布し、該第一塗膜用塗料が硬化する前に前記第一領域と前記第二領域に塗布された前記第一塗膜用塗料を掻き取ることにより、少なくとも前記第一領域の表面の一部に第一塗膜を形成するとともに、前記基材の表面を、前記第一領域よりも前記第二領域で多く露出させる第二のステップと、を備えるものである。 In addition, the eleventh aspect of the present invention is a method for manufacturing a building board, in which a first region having a plurality of first recesses and a plurality of second recesses adjacent to the first recess are formed. The first step of preparing a substrate having a second region, wherein the average depth of the plurality of first recesses of the first region is deeper than the average depth of the plurality of second recesses of the second region. Then, the paint for the first coating film was applied to the surfaces of the first region and the second region, and the paint for the first coating film was applied to the first region and the second region before the coating film was cured. By scraping off the paint for the first coating film, the first coating film is formed on at least a part of the surface of the first region, and the surface of the base material is formed in the second region rather than the first region. It includes a second step of exposing more.

本発明の第十一の態様の製造方法では、第二のステップにてワイピング塗装を採用し、第一領域に塗布された第一塗膜用塗料の一部と第二領域に塗布された第一塗膜用塗料の全部もしくは一部を掻き取り装置の掻き取り部にて掻き取って、第一塗膜が形成される部分と基材が露出する部分を形成するものである。 In the production method of the eleventh aspect of the present invention, wiping coating is adopted in the second step, and a part of the coating film for the first coating film applied to the first region and the first coating film applied to the second region. (I) All or part of the coating film coating material is scraped off by a scraping portion of the scraping device to form a portion where the first coating film is formed and a portion where the base material is exposed.

ここで、「少なくとも第一領域の表面の一部に第一塗膜を形成する」とは、第一領域の表面にのみ第一塗膜が形成されている形態の他、第二領域の表面にも第一塗膜が形成されている形態を含む意味である。 Here, "forming the first coating film on at least a part of the surface of the first region" means that the first coating film is formed only on the surface of the first region and the surface of the second region. Also includes the form in which the first coating film is formed.

また、「基材の表面を、第一領域よりも第二領域で多く露出させる」とは、基材の表面の露出面積が、第一領域よりも第二領域の方が広いことを意味する。 Further, "exposing the surface of the base material more in the second region than in the first region" means that the exposed area of the surface of the base material is wider in the second region than in the first region. ..

また、掻き取り部としては、例えば表面にスポンジ等の弾性材が配設された回転ロールやブラシなどをあげることができる。 Further, as the scraping portion, for example, a rotating roll or a brush on which an elastic material such as a sponge is arranged on the surface can be mentioned.

本発明の第十一の態様によれば、第二のステップの第一塗膜用塗料の掻き取りにおいて、第一領域と第二領域の凹部の平均深さの違いにより、第一塗膜による被覆状態と基材の表面の露出状態が異なる第一領域と第二領域を形成することができる。第一領域と第二領域は、第一塗膜による被覆状態と基材の表面の露出状態が異なることにより、外観が異なる。外観が異なる第一領域と第二領域が隣接しているので、第一領域と第二領域の境界は明確となり、縦目地を用いなくても複数種の柄模様を表現することができる、意匠性に優れた建築板を製造できる。さらに、この建築板は縦目地を用いずに柄模様を表現することができるので、どの部位で切断しても、縦目地による極端に横幅の狭い***部が形成されることがない。そのため、建築板の切断に際して余分な端材が発生するといった課題も解消され、建築板を用いた出隅用パネルの効率的な製造を実現できる。また、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 According to the eleventh aspect of the present invention, in the scraping of the paint for the first coating film in the second step, the first coating film is used due to the difference in the average depth of the recesses in the first region and the second region. It is possible to form a first region and a second region in which the coating state and the exposed state of the surface of the base material are different. The appearance of the first region and the second region is different due to the difference in the coating state by the first coating film and the exposed state of the surface of the base material. Since the first region and the second region, which have different appearances, are adjacent to each other, the boundary between the first region and the second region is clear, and a design capable of expressing multiple types of patterns without using vertical joints. It is possible to manufacture building boards with excellent properties. Further, since this building board can express a pattern without using vertical joints, no matter where the vertical joints are cut, an extremely narrow ridge portion due to the vertical joints is not formed. Therefore, the problem that extra scraps are generated when cutting the building board is solved, and it is possible to efficiently manufacture the protruding corner panel using the building board. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

また、本発明の第十二の態様による建築板の製造方法において、前記基材の表面は、第二塗膜によって形成されているものである。 Further, in the method for manufacturing a building board according to the twelfth aspect of the present invention, the surface of the base material is formed by a second coating film.

基材の表面に第二塗膜を形成する方法としては、例えば、第二のステップを行う前に基材全体に第二塗膜用塗料を塗布し、硬化させる方法、第二のステップを行う前に第一領域と第二領域に第二塗膜用塗料を塗布し、硬化させる方法、第二のステップを行う前に第二領域のみに第二塗膜用塗料を塗布し、硬化させる方法等が挙げられる。 As a method of forming the second coating film on the surface of the base material, for example, a method of applying the paint for the second coating film to the entire base material and curing it before performing the second step, and performing the second step. A method of applying the second coating film paint to the first region and the second region before and curing the method, and a method of applying the second coating film paint only to the second region and curing the second region before performing the second step. And so on.

本発明の第十二の態様によれば、第一領域の表面の一部には第一塗膜が形成されており、第二領域の表面には第一塗膜と異なる第二塗膜が露出した建築板を製造することができる。この建築板は、例えば第二塗膜の色を第一塗膜と異ならせると、第二領域の表面には第二塗膜が露出しているので、第一領域と第二領域の外観が大きく異なる。そして、第一領域と第二領域は隣接しているものの外観が大きく異なるので、第一領域と第二領域の境界は一層明確となり、目地を用いなくても複数種の柄模様を有する、意匠性に優れた建築板となる。 According to the twelfth aspect of the present invention, a first coating film is formed on a part of the surface of the first region, and a second coating film different from the first coating film is formed on the surface of the second region. Exposed building boards can be manufactured. In this building board, for example, when the color of the second coating film is different from that of the first coating film, the second coating film is exposed on the surface of the second region, so that the appearance of the first region and the second region is different. to differ greatly. Since the first region and the second region are adjacent to each other but the appearances are significantly different, the boundary between the first region and the second region becomes clearer, and the design has a plurality of types of patterns without using joints. It will be a building board with excellent properties.

さらに、この建築板は縦目地を用いずに柄模様を表現できるので、建築板を用いた出隅用パネルの効率的な製造を実現できる。また、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 Further, since this building board can express a pattern without using vertical joints, it is possible to efficiently manufacture a panel for outside corners using the building board. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

また、本発明の第十三の態様による建築板の製造方法は、前記基材は長手方向を有する平面視において長方形であり、前記第一凹部と前記第二凹部が該長手方向に延びており、前記第二のステップにおける塗料の掻き取りは、掻き取り装置の掻き取り部を前記基材の長手方向に対して交差するように配置して該基材に接触させ、該掻き取り部に対して相対的に該基材を移動させることによっておこなうものである。 Further, in the method for manufacturing a building board according to the thirteenth aspect of the present invention, the base material is rectangular in a plan view having a longitudinal direction, and the first recess and the second recess extend in the longitudinal direction. In the scraping of the paint in the second step, the scraping portion of the scraping device is arranged so as to intersect the longitudinal direction of the base material and is brought into contact with the base material, and the scraping portion is contacted. This is done by moving the base material relatively.

ここで、「掻き取り部に対して相対的に該基材を移動させる」とは、掻き取り部と基材のいずれか一方を移動させず、他方のみを移動させる形態や、掻き取り部と基材を双方の移動方向や移動速度を変化させながら移動させる形態があり、例えば後者の場合には、双方を同一方向で異なる速度で移動させる形態や双方を逆方向に移動させる形態がある。 Here, "moving the base material relative to the scraping portion" means a form in which one of the scraping portion and the base material is not moved and only the other is moved, or the scraping portion. There is a form in which the base material is moved while changing both moving directions and moving speeds. For example, in the latter case, there is a form in which both are moved in the same direction at different speeds and a form in which both are moved in opposite directions.

本発明の第十三の態様によれば、第二のステップにおける塗料の掻き取りを円滑に行うことができる。それにより、基材の露出部分が明確となるので、第一領域と第二領域の外観をより異ならせることができ、縦目地を用いなくても複数種の柄模様を有する、意匠性に優れた建築板を製造することができる。 According to the thirteenth aspect of the present invention, the paint can be smoothly scraped off in the second step. As a result, the exposed portion of the base material becomes clear, so that the appearances of the first region and the second region can be made more different, and there are multiple types of patterns without using vertical joints, which is excellent in design. It is possible to manufacture new building boards.

また、本発明の第十四の態様による建築板の製造方法は、前記掻き取り部は回転可能で有り、前記基材の移動方向に対して前記掻き取り部を逆方向に回転させて塗料を掻き取るものである。 Further, in the method for manufacturing a building board according to the fourteenth aspect of the present invention, the scraped portion is rotatable, and the scraped portion is rotated in the direction opposite to the moving direction of the base material to apply paint. It is something to scrape.

本発明の第十四の態様によれば、基材の移動方向に対して掻き取り部が逆方向に回転することで、掻き取り部が基材の第一凹部および第二凹部に入り込み易くなり、効率的な塗料の掻き取りを実行でき、第一塗膜の効率的な成膜をおこなうことができる。 According to the fourteenth aspect of the present invention, the scraped portion rotates in the direction opposite to the moving direction of the base material, so that the scraped portion easily enters the first recess and the second recess of the base material. , Efficient scraping of paint can be performed, and efficient film formation of the first coating film can be performed.

本発明の建築板とその製造方法によれば、第一塗膜による被覆状態と基材の露出状態の違いによって外観が異なる第一領域と第二領域を隣接して備えていることにより、目地を用いなくても第一領域と第二領域の境界が表現された、意匠性に優れた建築板となる。この境界によって縦目地を表現できるので、出隅用パネルの製造のためにこの建築板のどの部位で切断しても、従来の建築板のように縦目地による極端に横幅の狭い***部が形成されることがない。従って、建築板を用いた出隅用パネルの効率的な製造を実現でき、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなり、建築板の切断に際して余分な端材が発生するといった問題も生じない。 According to the building board of the present invention and the manufacturing method thereof, joints are provided by adjacently providing a first region and a second region whose appearance differs depending on the difference between the coating state by the first coating film and the exposed state of the base material. It is a building board with excellent design that expresses the boundary between the first area and the second area without using. Since vertical joints can be expressed by this boundary, no matter where part of this building board is cut for manufacturing a panel for outside corners, an extremely narrow ridge is formed by the vertical joints like a conventional building board. Will not be done. Therefore, it is possible to efficiently manufacture the projected corner panel using the building board, and the manufactured protruding corner panel is not easily chipped or damaged during its manufacturing, transportation, and storage, and the building board is cut. At this time, there is no problem that extra scraps are generated.

(Embodiment 1 of Building Board)
FIG. 1 is a plan view of the first embodiment of the building board of the present invention, and FIG. 2 is a sectional view taken along line II-II of FIG.

図示する建築板100は、基材10と、第一塗膜20と、から構成されている。また、基材10の表面は、第二塗膜10cによって形成されている。なお、図示する建築板100は、例えば長手方向Lの長さが約1.8m〜約3m程度、長手方向Lに直交する短手方向の長さが約0.5m程度であり、短手方向に沿って建築板100を複数のパネルに切断することにより、出隅用パネルが製作される。 The illustrated building board 100 is composed of a base material 10 and a first coating film 20. The surface of the base material 10 is formed by the second coating film 10c. The building board 100 shown in the drawing has, for example, a length of about 1.8 m to about 3 m in the longitudinal direction L and a length of about 0.5 m in the lateral direction orthogonal to the longitudinal direction L, and is in the lateral direction. By cutting the building board 100 into a plurality of panels along the above, a panel for protruding corners is manufactured.

基材10は、複数の第一凹部10aを有する第一領域Aと、第一領域Aに隣接し、複数の第二凹部10bを有する第二領域Bを備える。第一凹部10aの深さはt1であり、第二凹部10bの深さはt2である。 The base material 10 includes a first region A having a plurality of first recesses 10a and a second region B adjacent to the first region A and having a plurality of second recesses 10b. The depth of the first recess 10a is t1, and the depth of the second recess 10b is t2.

第一凹部10aの平均深さ、第二凹部10bの平均深さはそれぞれ、各第一凹部10aの深さt1、各第二凹部10bの深さt2から第一凹部10aの平均値と第二凹部10bの平均値を算出し、各凹部の深さとしている。なお、第一凹部10aと第二凹部10bの平均深さは設計データから算出することができるが、設計データが無い場合には、各領域内の任意の凹部十点程度をマイクロスコープ、デプスゲージ等で測定し、算出することができる。 The average depth of the first recess 10a and the average depth of the second recess 10b are the average value of the first recess 10a and the average value of the first recess 10a from the depth t1 of each first recess 10a and the depth t2 of each second recess 10b, respectively. The average value of the recesses 10b is calculated and used as the depth of each recess. The average depth of the first recess 10a and the second recess 10b can be calculated from the design data, but if there is no design data, about ten arbitrary recesses in each region can be measured with a microscope, depth gauge, etc. Can be measured and calculated with.

建築板100では、第一領域Aにおける第一凹部10aの平均深さが第二領域Bにおける第二凹部10bの平均深さよりも深くなっている。一例として、第一凹部10aの平均深さを約1.5mm程度、第二凹部10bの平均深さを約0.5mm程度に設定することができる。 In the building board 100, the average depth of the first recess 10a in the first region A is deeper than the average depth of the second recess 10b in the second region B. As an example, the average depth of the first recess 10a can be set to about 1.5 mm, and the average depth of the second recess 10b can be set to about 0.5 mm.

基材10の表面Pは第二塗膜10cによって形成されており、第二塗膜10cは基材10の表面全体を覆っている。 The surface P of the base material 10 is formed by the second coating film 10c, and the second coating film 10c covers the entire surface of the base material 10.

そして、第二領域Bにおいて、複数の第二凹部10bの表面には基材10の表面である第二塗膜10cが露出している。 Then, in the second region B, the second coating film 10c, which is the surface of the base material 10, is exposed on the surfaces of the plurality of second recesses 10b.

また、第二領域Bは、複数の第二凸部60Bを有する。第二凸部60Bは第二凹部10b間に形成されている。第二凸部60Bの表面には、基材10の表面である第二塗膜10cが露出している。 Further, the second region B has a plurality of second convex portions 60B. The second convex portion 60B is formed between the second concave portions 10b. On the surface of the second convex portion 60B, the second coating film 10c, which is the surface of the base material 10, is exposed.

一方、第一領域Aにおいて、複数の第一凹部10aの表面には第一塗膜20が形成されている。より具体的には、第一塗膜20は、基材10の表面Pである第二塗膜10cの上に形成されている。 On the other hand, in the first region A, the first coating film 20 is formed on the surfaces of the plurality of first recesses 10a. More specifically, the first coating film 20 is formed on the second coating film 10c, which is the surface P of the base material 10.

また、第一領域Aは、複数の第一凸部50Bを有する。第一凸部50Bは第一凹部10a間に形成されている。第一凸部50Bの表面には、基材10の表面Pである第二塗膜10cが露出している。 Further, the first region A has a plurality of first convex portions 50B. The first convex portion 50B is formed between the first concave portions 10a. On the surface of the first convex portion 50B, the second coating film 10c, which is the surface P of the base material 10, is exposed.

図2で示すように、建築板100において、第一領域Aは第一凹部10aと第一凸部50Bからなり、第二領域Bは第二凹部10bと第二凸部60Bからなる。 As shown in FIG. 2, in the building board 100, the first region A is composed of the first concave portion 10a and the first convex portion 50B, and the second region B is composed of the second concave portion 10b and the second convex portion 60B.

ここで、第一領域Aの第一凹部10aの表面には第一塗膜20が形成されており、第一領域Aの第一凸部50Bの表面には基材10の表面Pである第二塗膜10cが露出している。そのため、第一領域Aの表面は、第一塗膜20が形成された部分と第二塗膜10cが露出した部分を有する。 Here, the first coating film 20 is formed on the surface of the first concave portion 10a of the first region A, and the surface P of the base material 10 is on the surface of the first convex portion 50B of the first region A. The two coating films 10c are exposed. Therefore, the surface of the first region A has a portion where the first coating film 20 is formed and a portion where the second coating film 10c is exposed.

一方、第二領域Bの第二凹部10bの表面と第二凸部60Bの表面には基材10の表面Pである第二塗膜10cが露出している。そのため、第二領域Bの表面は、第二塗膜10cが露出した部分を有する。なお、図2では第二領域Bに第一塗膜20を有していないが、第二凹部10bの一部に若干の第一塗膜20が形成されていても良い。 On the other hand, the second coating film 10c, which is the surface P of the base material 10, is exposed on the surface of the second concave portion 10b and the surface of the second convex portion 60B of the second region B. Therefore, the surface of the second region B has a portion where the second coating film 10c is exposed. Although the second region B does not have the first coating film 20 in FIG. 2, a small amount of the first coating film 20 may be formed in a part of the second recess 10b.

第一領域Aでは、第一凸部50Bで第二塗膜10cが露出しているのに対し、第二領域Bでは、第二凹部10bと第一凸部60Bで第二塗膜10cが露出している。そのため、基材10の表面Pである第二塗膜10cの露出は、第一領域Aよりも第二領域Bで多い。 In the first region A, the second coating film 10c is exposed in the first convex portion 50B, whereas in the second region B, the second coating film 10c is exposed in the second concave portion 10b and the first convex portion 60B. is doing. Therefore, the exposure of the second coating film 10c, which is the surface P of the base material 10, is larger in the second region B than in the first region A.

第一領域Aと第二領域Bは、各凹部の平均深さの違いにより、第一塗膜20の被覆状態と基材10の露出状態が異なるので、外観が異なる。外観が異なる第一領域Aと第二領域Bが隣接しているので、第一領域Aと第二領域Bの境界が表現されることとなる。それにより、建築板100は、縦目地を用いなくても複数種の柄模様が表現できる。 The appearance of the first region A and the second region B is different because the coating state of the first coating film 20 and the exposed state of the base material 10 are different due to the difference in the average depth of each recess. Since the first region A and the second region B having different appearances are adjacent to each other, the boundary between the first region A and the second region B is expressed. As a result, the building board 100 can express a plurality of types of patterns without using vertical joints.

また、図1で示すように、第一領域Aと第二領域Bはともに同寸法で平面視において矩形を呈しており、図示例では、第一領域Aと第二領域Bが上下左右で交互に配置されている。 Further, as shown in FIG. 1, both the first region A and the second region B have the same dimensions and are rectangular in a plan view. In the illustrated example, the first region A and the second region B alternate vertically and horizontally. Is located in.

凹部の平均深さと基材10の露出状態が異なるブロック調の複数の第一領域Aと第二領域Bが上下左右に並んで配置されていることから、縦目地を用いることなく、ブロック調の模様が表現されている。 Since a plurality of block-like first regions A and second regions B having different average depths of the recesses and the exposed state of the base material 10 are arranged side by side in the vertical and horizontal directions, the block-like joints are not used. The pattern is expressed.

また、図1で示すように、建築板100は平面視において長方形であり、第一領域Aの第一凹部10aと第二領域Bの第二凹部10bがともに建築板100の長手方向Lと同一方向に延びている。 Further, as shown in FIG. 1, the building board 100 is rectangular in a plan view, and both the first recess 10a in the first region A and the second recess 10b in the second region B are the same as the longitudinal direction L of the building board 100. It extends in the direction.

さらに、第一領域Aの第一凸部50Bの高さ(基材10の裏面からの距離s)と、第二領域Bの第二凸部60Bの高さ(基材10の裏面からの距離s)は同一である。 Further, the height of the first convex portion 50B of the first region A (distance s from the back surface of the base material 10) and the height of the second convex portion 60B of the second region B (distance from the back surface of the base material 10). s) are the same.

第一領域Aの複数の第一凸部50Bと第二領域Bの複数の第二凸部60Bの高さが同一であることにより、見た目の統一感が図られる。 Since the heights of the plurality of first convex portions 50B of the first region A and the plurality of second convex portions 60B of the second region B are the same, a sense of unity in appearance can be achieved.

ここで、基材10には表面Pが第二塗膜10cによって形成された、例えばセメント板、金属板、樹脂板などが適用できる。 Here, for example, a cement plate, a metal plate, a resin plate, or the like in which the surface P is formed by the second coating film 10c can be applied to the base material 10.

第一塗膜20と第二塗膜10cは樹脂と顔料からなる塗料を使用して成膜される。ここで、樹脂としては、例えばアクリル樹脂、アクリルシリコン樹脂、シリコン樹脂、フッ素樹脂、ポリウレタン樹脂、エポキシ樹脂等が適用でき、顔料としては、例えば炭酸カルシウム、クレー、酸化チタン、カーボン、弁柄、黄鉛、酸化鉄、ウルトラマリン、フタロシアニンブルー、コバルト、酸化クロム等が適用できる。さらに、必要に応じて、消泡剤、pH調整剤、光安定剤、紫外線吸収剤などを含有させてもよい。 The first coating film 20 and the second coating film 10c are formed by using a paint composed of a resin and a pigment. Here, as the resin, for example, acrylic resin, acrylic silicon resin, silicon resin, fluororesin, polyurethane resin, epoxy resin and the like can be applied, and as the pigment, for example, calcium carbonate, clay, titanium oxide, carbon, valve handle, yellow and the like can be applied. Lead, iron oxide, ultramarine, phthalocyanine blue, cobalt, chromium oxide, etc. can be applied. Further, if necessary, an antifoaming agent, a pH adjuster, a light stabilizer, an ultraviolet absorber and the like may be contained.

建築板100において、第二領域Bでは基材10の表面Pである第二塗膜10cが露出し、第一領域Aでは第一塗膜20が表面に露出していることから、双方の塗膜の色を変化させておくことで、第一領域Aと第二領域Bの色の変化を一層顕著にすることができる。 In the building board 100, the second coating film 10c, which is the surface P of the base material 10, is exposed in the second region B, and the first coating film 20 is exposed on the surface in the first region A. By changing the color of the film, the change in color between the first region A and the second region B can be made more remarkable.

このように、建築板100は、平面視において矩形(ブロック調)の第一領域Aと第二領域Bが上下左右に並び、双方の領域A,Bの第一凹部10a、第二凹部10bの平均深さが相互に異なることにより、第一塗膜20による各領域の被覆状態と基材の表面の露出状態が異なるので、第一領域Aと第二領域Bの外観が異なる。外観が異なる第一領域Aと第二領域Bが隣接しているので、第一領域Aと第二領域Bの境界が表現され、縦目地を用いなくてもブロック調の柄模様を表現することができ、意匠性に優れた建築板100となっている。 As described above, in the building board 100, the rectangular (block-like) first region A and the second region B are arranged vertically and horizontally in the plan view, and the first recesses 10a and the second recesses 10b of both regions A and B are arranged. Since the average depths are different from each other, the coating state of each region by the first coating film 20 and the exposed state of the surface of the base material are different, so that the appearances of the first region A and the second region B are different. Since the first region A and the second region B, which have different appearances, are adjacent to each other, the boundary between the first region A and the second region B is expressed, and a block-like pattern is expressed without using vertical joints. It is a building board 100 with excellent design.

双方の領域A,Bの色も相違していることから、領域A,Bの境界を、縦目地を用いずに表現できるとともに、異なる色調による意匠効果が奏される。 Since the colors of both regions A and B are also different, the boundary between regions A and B can be expressed without using vertical joints, and a design effect with different color tones is produced.

さらに、領域A,Bにおいて、第一凹部10a、第二凹部10bがともに建築板100の長手方向Lと同一方向に延びていることにより、全体的な統一感が得られ、このことによっても建築板100の意匠性が高められる。 Further, in the areas A and B, both the first recess 10a and the second recess 10b extend in the same direction as the longitudinal direction L of the building board 100, so that an overall sense of unity can be obtained. The design of the board 100 is enhanced.

さらに、建築板100は、縦溝(従来の建築板の縦目地)を備えておらず、平面視において矩形の第一領域Aと第二領域Bが上下左右で交互に配置された構成を備えているのみである。したがって、建築板100を例えば長手方向Lに直交する短手方向に沿って切断して出隅用パネルを製造しようとした際に、建築板100のどの部位で切断したとしても、従来の縦目地を有する建築板のように縦目地による極端に横幅の狭い***部が形成されることがなく、建築板100を用いた出隅用パネルの効率的な製造を実現することができる。さらに、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなり、建築板100の切断に際して余分な端材が発生するといった課題も生じ得ない。 Further, the building board 100 does not have vertical grooves (vertical joints of the conventional building board), and has a configuration in which rectangular first regions A and second regions B are alternately arranged vertically and horizontally in a plan view. Is only. Therefore, when the building board 100 is cut along the lateral direction orthogonal to the longitudinal direction L, for example, to manufacture the projected corner panel, no matter which part of the building board 100 is cut, the conventional vertical joint is used. It is possible to efficiently manufacture a protruding corner panel using the building board 100 without forming an extremely narrow raised portion due to vertical joints as in the building board having the above. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage, and there cannot be a problem that extra scraps are generated when cutting the building board 100.

なお、図示を省略するが、第二領域Bの第二凹部10bの表面の一部に第一塗膜20をさらに備えていてもよい。この形態であっても、第二凹部10bには基材10の表面Pである第二塗膜10cが露出しているので、第一領域Aと第二領域Bは異なる色調となり、縦目地を用いなくても複数種の柄模様を表現する効果と、出隅用パネルの効率的な製造を実現する効果が奏される。 Although not shown, the first coating film 20 may be further provided on a part of the surface of the second recess 10b in the second region B. Even in this form, since the second coating film 10c, which is the surface P of the base material 10, is exposed in the second recess 10b, the first region A and the second region B have different color tones, and the vertical joints are formed. The effect of expressing multiple types of patterns without using it and the effect of realizing efficient production of protruding corner panels are achieved.

(建築板の実施の形態2)
図3は建築板の実施の形態2の断面図である。図示する建築板100Aも、第一領域Aと第二領域Bを上下左右で交互に配置するものであり、基材10Aと、第一塗膜20Aとから構成されている。しかし、基材10Aの表面P’には塗膜が存在しないことが建築板100と異なる。
(Embodiment 2 of building board)
FIG. 3 is a cross-sectional view of the second embodiment of the building board. The illustrated building board 100A also has the first region A and the second region B arranged alternately in the vertical and horizontal directions, and is composed of the base material 10A and the first coating film 20A. However, it differs from the building board 100 in that no coating film is present on the surface P'of the base material 10A.

基材10Aは、複数の第一凹部10aを有する第一領域Aと、第一領域Aに隣接し、複数の第二凹部10bを有する第二領域Bを備える。第一凹部10aの深さはt1’、第二凹部10bの深さはt2’である。 The base material 10A includes a first region A having a plurality of first recesses 10a and a second region B adjacent to the first region A and having a plurality of second recesses 10b. The depth of the first recess 10a is t1', and the depth of the second recess 10b is t2'.

建築板100Aも、第一領域Aにおける第一凹部10aの平均深さが第二領域Bにおける第二凹部10bの平均深さよりも深くなっている。第一凹部10a、第二凹部10bはともに建築板100Aの長手方向と同一方向に延びている。 In the building board 100A, the average depth of the first recess 10a in the first region A is deeper than the average depth of the second recess 10b in the second region B. Both the first recess 10a and the second recess 10b extend in the same direction as the longitudinal direction of the building board 100A.

そして、第二領域Bにおいて、複数の第二凹部10bの表面には基材10Aの表面P’が露出している。 Then, in the second region B, the surface P'of the base material 10A is exposed on the surfaces of the plurality of second recesses 10b.

また、第二領域Bは、第二凹部10b間に形成されている、複数の第二凸部60Bを有する。第二凸部60Bの表面には、基材10Aの表面P’が露出している。 Further, the second region B has a plurality of second convex portions 60B formed between the second concave portions 10b. The surface P'of the base material 10A is exposed on the surface of the second convex portion 60B.

一方、第一領域Aにおいて、複数の第一凹部10aの表面には第一塗膜20Aが形成されている。 On the other hand, in the first region A, the first coating film 20A is formed on the surfaces of the plurality of first recesses 10a.

また、第一領域Aは、第一凹部10a間に形成されている、複数の第一凸部50Bを有する。第一凸部50Bの表面には、塗膜を具備しない基材10Aの表面P’が露出している。 Further, the first region A has a plurality of first convex portions 50B formed between the first concave portions 10a. On the surface of the first convex portion 50B, the surface P'of the base material 10A having no coating film is exposed.

図3で示すように、建築板100Aにおいて、第一領域Aは第一凹部10aと第一凸部50Bからなり、第二領域Bは第二凹部10bと第二凸部60Bからなる。 As shown in FIG. 3, in the building board 100A, the first region A is composed of the first concave portion 10a and the first convex portion 50B, and the second region B is composed of the second concave portion 10b and the second convex portion 60B.

ここで、第一領域Aの第一凹部10aの表面には第一塗膜20Aが形成されており、第一領域Aの第一凸部50Bの表面には塗膜を具備しない基材10Aの表面P’が露出している。そのため、第一領域Aの表面は、第一塗膜20Aが形成された部分と塗膜を具備しない基材10Aの表面P’が露出した部分を有する。 Here, the first coating film 20A is formed on the surface of the first concave portion 10a of the first region A, and the surface of the first convex portion 50B of the first region A does not have a coating film. The surface P'is exposed. Therefore, the surface of the first region A has a portion where the first coating film 20A is formed and a portion where the surface P'of the base material 10A having no coating film is exposed.

一方、第二領域Bの第二凹部10bの表面と第二凸部60Bの表面には塗膜を具備しない基材10Aの表面P’が露出している。そのため、第二領域Bの表面は、塗膜を具備しない基材10Aの表面P’が露出した部分を有する。 On the other hand, the surface P'of the base material 10A having no coating film is exposed on the surface of the second concave portion 10b and the surface of the second convex portion 60B of the second region B. Therefore, the surface of the second region B has a portion where the surface P'of the base material 10A having no coating film is exposed.

第一領域Aでは、第一凸部50Bで塗膜を具備しない基材10Aの表面P’が露出しているのに対し、第二領域Bでは、第二凹部10bと第二凸部60Bで塗膜を具備しない基材10Aが露出している。そのため、塗膜を具備しない基材10Aの表面P’の露出は、第一領域Aよりも第二領域Bで多い。 In the first region A, the surface P'of the base material 10A having no coating film is exposed in the first convex portion 50B, whereas in the second region B, the second concave portion 10b and the second convex portion 60B are exposed. The base material 10A that does not have a coating film is exposed. Therefore, the exposure of the surface P'of the base material 10A without the coating film is larger in the second region B than in the first region A.

第一領域Aと第二領域Bは、凹部の平均深さの違いにより、第一塗膜20Aの被覆状態と基材10Aの露出状態が異なるので、外観が異なる。外観が異なる第一領域Aと第二領域Bが隣接しているので、第一領域Aと第二領域Bの境界が表現されることとなる。それにより、建築板100Aは、縦目地を用いなくても複数種の柄模様が表現できる。 The appearances of the first region A and the second region B are different because the coating state of the first coating film 20A and the exposed state of the base material 10A are different due to the difference in the average depth of the recesses. Since the first region A and the second region B having different appearances are adjacent to each other, the boundary between the first region A and the second region B is expressed. As a result, the building board 100A can express a plurality of types of patterns without using vertical joints.

また、建築板100Aでは、第一領域Aの第一凹部10aにおいて第一塗膜20Aが露出し、第二領域Bの第二凹部10bにおいて塗膜を具備しない基材10Aが露出していることから、基材10Aの色と第一塗膜20Aの色の相違により、第一領域Aと第二領域Bの境界を、縦目地を用いずに表現できるとともに、異なる色調による意匠効果が奏される。 Further, in the building board 100A, the first coating film 20A is exposed in the first recess 10a of the first region A, and the base material 10A having no coating film is exposed in the second recess 10b of the second region B. Therefore, by the difference between the color of the base material 10A and the color of the first coating film 20A, the boundary between the first region A and the second region B can be expressed without using vertical joints, and the design effect due to the different color tones is produced. NS.

なお、基材10Aには、セメント板、金属板、樹脂板などが適用できる。基材10Aにセメント板を適用した場合、基材10Aは通常、灰色を呈しているが、基材10Aの製造過程で顔料を添加することにより、基材10Aの色を変化させることができる。例えば、カーボンブラック、アセチレンブラック、黒鉛等の黒色顔料を含有させることで黒色の基材10Aが得られる。また、例えば、黄鉛、亜鉛黄、クロム酸バリウム、カドミウム黄、黄色酸化鉄等の黄色顔料を含有させることで黄色の基材10Aが得られる。 A cement plate, a metal plate, a resin plate, or the like can be applied to the base material 10A. When the cement plate is applied to the base material 10A, the base material 10A is usually gray, but the color of the base material 10A can be changed by adding a pigment in the manufacturing process of the base material 10A. For example, a black base material 10A can be obtained by containing a black pigment such as carbon black, acetylene black, or graphite. Further, for example, a yellow base material 10A can be obtained by containing a yellow pigment such as chrome yellow, zinc yellow, barium chromate, cadmium yellow, and yellow iron oxide.

また、建築板100Aも、第一領域Aの複数の第一凸部50Bと第二領域Bの複数の第二凸部60Bの高さ(基材10Aの裏面からの距離)が同一であることにより、見た目の統一感が図られる。 Further, in the building board 100A, the heights (distance from the back surface of the base material 10A) of the plurality of first convex portions 50B of the first region A and the plurality of second convex portions 60B of the second region B are the same. As a result, a sense of unity in appearance is achieved.

更に、図示していないが、第一領域Aと第二領域Bはともに同寸法で平面視において矩形を呈していること、第一領域Aと第二領域Bが上下左右で交互に配置されていること、建築板100Aは平面視において長方形であり、第一領域Aの第一凹部10aと第二領域Bの第二凹部10bがともに建築板の長手方向Lと同一方向に延びていることは建築板100と同じであり、同様の効果を奏する。 Further, although not shown, the first region A and the second region B both have the same dimensions and have a rectangular shape in a plan view, and the first region A and the second region B are alternately arranged vertically and horizontally. That is, the building board 100A is rectangular in a plan view, and the first recess 10a of the first region A and the second recess 10b of the second region B both extend in the same direction as the longitudinal direction L of the building board. It is the same as the building board 100 and has the same effect.

このように、建築板100Aも縦目地を用いずに柄模様を表現しているので、どの部位で切断しても、縦目地による極端に横幅の狭い***部が形成されることがない。そのため、建築板の切断に際して余分な端材が発生するといった課題も解消され、建築板を用いた出隅用パネルの効率的な製造を実現できる。また、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 As described above, since the building board 100A also expresses the pattern pattern without using the vertical joints, no matter where the vertical joints are cut, an extremely narrow ridge portion due to the vertical joints is not formed. Therefore, the problem that extra scraps are generated when cutting the building board is solved, and it is possible to efficiently manufacture the protruding corner panel using the building board. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

(建築板の実施の形態3,4)
図4,5はそれぞれ、建築板の実施の形態3,4の平面図である。図4で示す建築板100B、図5で示す建築板100Cともに、第一領域Aと第二領域Bが横方向に並ぶ一段を上下で区切る横溝を備えている点で共通している。
(Embodiments 3 and 4 of building boards)
4 and 5 are plan views of the third and fourth embodiments of the building board, respectively. Both the building board 100B shown in FIG. 4 and the building board 100C shown in FIG. 5 are common in that the first area A and the second area B are provided with a horizontal groove that vertically separates one step in which the first area A and the second area B are arranged in the horizontal direction.

具体的には、建築板100Bは、その長手方向Lに沿って延びている一本の横溝70にて各段が上下方向に区切られており、各領域A,Bが横方向に並んでできる各段が上下の横溝70で挟まれて構成されている。 Specifically, in the building board 100B, each step is divided in the vertical direction by a single horizontal groove 70 extending along the longitudinal direction L, and the areas A and B can be arranged in the horizontal direction. Each step is sandwiched between upper and lower horizontal grooves 70.

一方、建築板100Cは、その長手方向Lに沿って延びている三本の横溝で形成された横溝70Aや、上下に幅を持たせた二本の横溝で形成された横溝70Bといった異なる種類の横溝70A,70Bを単独で、もしくは組み合わせて用いることにより、独自の意匠性を醸し出している。 On the other hand, the building board 100C has different types such as a lateral groove 70A formed by three lateral grooves extending along the longitudinal direction L and a lateral groove 70B formed by two lateral grooves having widths in the vertical direction. By using the lateral grooves 70A and 70B alone or in combination, a unique design is created.

なお、建築板100B,100Cともに、横溝を有すること以外は建築板100と同じである。 Both the building boards 100B and 100C are the same as the building board 100 except that they have a lateral groove.

建築板100B,100Cともに、それぞれそれらの長手方向Lに沿って延びている横溝70,70A,70Bで平面視矩形の各領域A,Bが横方向に並んで構成される各段を上下に区切っていることにより、第一領域Aと第二領域Bの境界の一部が横目地に相当する横溝70,70A,70Bによって明確に表現でき、縦目地は第一領域Aと第二領域Bの塗膜の差で表現できるので、意匠性に優れた建築板100B,100Cとなる。 For both the building boards 100B and 100C, the horizontal grooves 70, 70A, and 70B extending along the longitudinal direction L of the building boards 100B and 100C divide each step formed by arranging the rectangular regions A and B in the plan view in the horizontal direction. Therefore, a part of the boundary between the first region A and the second region B can be clearly expressed by the lateral grooves 70, 70A, 70B corresponding to the horizontal joints, and the vertical joints of the first region A and the second region B. Since it can be expressed by the difference in the coating film, the building boards 100B and 100C have excellent design.

さらに、各領域A,Bの第一凹部50A、第二凹部60Aと横溝70,70A,70Bがともに同一方向に延びていることによっても、見た目の統一感が図られ、意匠性に優れた建築板100B,100Cとなる。 Further, the first recesses 50A and the second recesses 60A and the lateral grooves 70, 70A and 70B of each of the areas A and B extend in the same direction, so that the appearance is unified and the architecture is excellent in design. The plates are 100B and 100C.

なお、建築板100B,100Cにおいても縦溝を具備しないことにより、既述する縦溝を具備する場合の様々な課題は生じ得ない。 It should be noted that even in the building boards 100B and 100C, since the vertical grooves are not provided, various problems cannot occur when the vertical grooves are provided as described above.

また、建築板100B,100Cにおいても、横溝を有すること以外は建築板100と同じであるので、建築板100と同様の効果も奏する。 Further, since the building boards 100B and 100C are the same as the building board 100 except that they have a lateral groove, the same effect as that of the building board 100 can be obtained.

(建築板の製造方法の実施の形態1)
次に、図6を参照して、建築板の製造方法の実施の形態1を説明する。この製造方法は、建築板100の製造方法である。
(Embodiment 1 of the method for manufacturing a building board)
Next, the first embodiment of the method for manufacturing a building board will be described with reference to FIG. This manufacturing method is a manufacturing method of the building board 100.

まず、複数の第一凹部10aと第一凸部50Bを有する第一領域Aと、第一領域Aに隣接し、複数の第二凹部10bと第二凸部60Bを有する第二領域Bを備え、第一凹部10aの平均深さは、第二凹部10bの平均深さよりも深い基材10を準備する(図2参照、第一のステップ)。 First, a first region A having a plurality of first concave portions 10a and a first convex portion 50B, and a second region B adjacent to the first region A and having a plurality of second concave portions 10b and a second convex portion 60B are provided. A base material 10 having an average depth of the first recess 10a deeper than the average depth of the second recess 10b is prepared (see FIG. 2, first step).

より具体的には、製作する柄と凹凸が反転した型板を用意し、この型板の上に原料(例えばセメント、フライアッシュ、マイカ、フレークなど)を散布してマットを形成する。最後にこのマットをプレスし、温度をかけて養生する。そして、本実施の形態では、表面全体に第二塗膜用塗料を塗布し、硬化させることで、表面に第二塗膜10cを有する基材10が製造される。 More specifically, a template in which the pattern to be produced and the unevenness are inverted is prepared, and a raw material (for example, cement, fly ash, mica, flakes, etc.) is sprayed on the template to form a mat. Finally, press this mat and heat it to cure. Then, in the present embodiment, the base material 10 having the second coating film 10c on the surface is manufactured by applying the coating material for the second coating film on the entire surface and curing the coating film.

次に、基材10の表面全体に第一塗膜用塗料を塗布し、この状態で基材10を図6(a)で示すように上下に回転ロールR1,R2を備えた掻き取り装置内に移動させる(X1方向)。 Next, the paint for the first coating film is applied to the entire surface of the base material 10, and in this state, the base material 10 is placed in a scraping device provided with rotating rolls R1 and R2 up and down as shown in FIG. 6A. (X1 direction).

ここで、掻き取り部である上方の回転ロールR1の表面にはスポンジ等の弾性材Eが配設されており、回転ロールR1は基材10の移動方向と逆方向(X2方向)に回転している。 Here, an elastic material E such as a sponge is disposed on the surface of the upper rotating roll R1 which is a scraping portion, and the rotating roll R1 rotates in the direction opposite to the moving direction of the base material 10 (X2 direction). ing.

第一塗膜用塗料が硬化する前に上下の回転ロールR1,R2間に基材10を通過させる過程で、図6(b)で示すように、第一領域Aの第一凹部10aと第二領域Bの第二凹部10bに弾性材Eが入り込み(X3方向)、第一領域Aに塗布された第一塗膜用塗料の一部と第二領域Bに塗布された第一塗膜用塗料の全部が掻き取られる。 In the process of passing the base material 10 between the upper and lower rotating rolls R1 and R2 before the coating film for the first coating film is cured, as shown in FIG. 6B, the first recess 10a and the first recess 10a of the first region A The elastic material E enters the second recess 10b of the second region B (in the X3 direction), and a part of the paint for the first coating film applied to the first region A and the first coating film applied to the second region B. All of the paint is scraped off.

所定時間の経過もしくは乾燥設備で乾燥させることにより、第一領域Aにおいて掻き取られずに残った第一塗膜用塗料の一部が硬化して第一塗膜20が形成される。それにより、第一凹部10aには第一塗膜20が形成され、第二凹部10b、第一凸部50Bと第二凸部60Bには、基材10の表面である第二塗膜10cが露出して、実施の形態1にかかる建築板100が製造される(第二のステップ)。 By elapse of a predetermined time or drying in a drying facility, a part of the paint for the first coating film remaining without being scraped off in the first region A is cured to form the first coating film 20. As a result, the first coating film 20 is formed in the first concave portion 10a, and the second coating film 10c, which is the surface of the base material 10, is formed in the second concave portion 10b, the first convex portion 50B and the second convex portion 60B. Exposed, the building board 100 according to the first embodiment is manufactured (second step).

なお、建築板の実施の形態3,4についても、第一のステップで横溝を備えた基材を準備すること以外は、同様に製造することができる。 It should be noted that the third and fourth embodiments of the building board can also be manufactured in the same manner except that the base material having the lateral groove is prepared in the first step.

また、建築板の実施の形態1で前述したように、第二領域Bの第二凹部10bに塗布された第一塗膜用塗料を全部掻き取るのではなく、一部掻き取ることもできる。 Further, as described above in the first embodiment of the building board, it is possible to scrape off not all the paint for the first coating film applied to the second recess 10b of the second region B, but a part of it.

このように、実施の形態1の製造方法によれば、凹部の平均深さの違いにより、第一塗膜20の被覆状態と基材10の露出状態が異なる第一領域Aと第二領域Bを形成することができる。第一領域Aと第二領域Bは、第一塗膜20の被覆状態と基材10の露出状態が異なることにより外観が異なる。外観が異なる第一領域Aと第二領域Bが隣接しているので、第一領域Aと第二領域Bの境界が表現されることとなる。それにより、建築板100は、縦目地を用いなくても複数種の柄模様が表現できる。 As described above, according to the manufacturing method of the first embodiment, the first region A and the second region B have different coating states of the first coating film 20 and exposed states of the base material 10 due to the difference in the average depth of the recesses. Can be formed. The appearance of the first region A and the second region B is different because the coating state of the first coating film 20 and the exposed state of the base material 10 are different. Since the first region A and the second region B having different appearances are adjacent to each other, the boundary between the first region A and the second region B is expressed. As a result, the building board 100 can express a plurality of types of patterns without using vertical joints.

また、実施の形態1の製造方法によって製造される建築板100は縦目地を用いずに柄模様を表現しているので、どの部位で切断しても、縦目地による極端に横幅の狭い***部が形成されることがない。そのため、建築板の切断に際して余分な端材が発生するといった課題も解消され、建築板を用いた出隅用パネルの効率的な製造を実現できる。また、製造された出隅用パネルもその製造や運搬、保管の際に欠け難く、損傷し難いものとなる。 Further, since the building board 100 manufactured by the manufacturing method of the first embodiment expresses a pattern without using vertical joints, a raised portion having an extremely narrow width due to the vertical joints can be cut at any part. Is never formed. Therefore, the problem that extra scraps are generated when cutting the building board is solved, and it is possible to efficiently manufacture the protruding corner panel using the building board. Further, the manufactured protruding corner panel is also hard to be chipped and damaged during its manufacturing, transportation, and storage.

(建築板の製造方法の実施の形態2)
次に、建築板の製造方法の実施の形態2を説明する。この製造方法は、建築板100Aの製造方法である。
(Embodiment 2 of the method for manufacturing a building board)
Next, the second embodiment of the method for manufacturing a building board will be described. This manufacturing method is a manufacturing method of the building board 100A.

まず、複数の第一凹部10aと第一凸部50Bを有する第一領域Aと、複数の第二凹部10bと第二凸部60Bを有する第二領域Bを備え、第一凹部10aの平均深さは、第二凹部10bの平均深さよりも深い基材10Aを準備する(図3参照、第一のステップ)。なお、本実施の形態においては、基材10Aの表面には第二塗膜を設けない。 First, a first region A having a plurality of first concave portions 10a and a first convex portion 50B, a second region B having a plurality of second concave portions 10b and a second convex portion 60B, and an average depth of the first concave portions 10a are provided. The base material 10A, which is deeper than the average depth of the second recess 10b, is prepared (see FIG. 3, first step). In the present embodiment, the second coating film is not provided on the surface of the base material 10A.

以後の第二のステップについては、建築板の製造方法の実施の形態1と同じである。 The second step thereafter is the same as in the first embodiment of the method for manufacturing a building board.

以上、本発明の実施の形態を図面を用いて詳述してきたが、具体的な構成はこの実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲における設計変更等があっても、それらは本発明に含まれるものである。例えば、図示例の建築板は、凹部の深さの異なる第一領域と第二領域から構成されるものであるが、第一領域および第二領域の各凹部と深さの異なる第三領域をさらに備え、第一領域の凹部の平均深さが約1.5mm程度、第二領域の凹部の平均深さが約1.0mm程度、第三領域の凹部の平均深さが約0.5mm程度の建築板も本願発明に含まれるものである。また、例えば、第一領域は、第一凹部の平均深さが第二凹部の平均深さよりも深いものであれば、第一凹部の一つとして第二凹部の平均深さよりも浅い凹部を含むこともできる。 Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like within a range that does not deviate from the gist of the present invention. Also, they are included in the present invention. For example, the building board of the illustrated example is composed of a first region and a second region having different depths of the recesses, but each recess in the first region and the second region and a third region having a different depth are formed. Further prepared, the average depth of the recesses in the first region is about 1.5 mm, the average depth of the recesses in the second region is about 1.0 mm, and the average depth of the recesses in the third region is about 0.5 mm. The building board of is also included in the present invention. Further, for example, if the average depth of the first recess is deeper than the average depth of the second recess, the first region includes a recess shallower than the average depth of the second recess as one of the first recesses. You can also do it.
