Abstract
Description
本発明は、一般に建築板に関し、より詳細には複数の凸部を備える建築板に関する。 The present invention generally relates to a building board, and more particularly to a building board having a plurality of convex portions.
特許文献１には、表面に溝状の目地が設けられたセメント組成体（基材）の仕上げ方法が開示されている。この方法は、目地塗装工程と、マスキング工程と、表面塗装工程と、マスキング材除去工程と、を有している。 Patent Document 1 discloses a method for finishing a cement composition (base material) having groove-shaped joints on its surface. This method includes a joint coating step, a masking step, a surface coating step, and a masking material removing step.
特許文献１には、基材として押出成形セメント板を用いてもよい旨が記載されている（段落［００３７］）。押出成形セメント板は、押出成形機によりセメント成形材料を押し出しながら、ローラーで化粧目地（以下、単に「目地」といい、縦目地及び横目地などがある）を設けた後、養生硬化して得られる。ローラーの外周には、周方向に横目地用の凸部が設けられ、回転軸方向に縦目地用の凸部が設けられている。 Patent Document 1 describes that an extruded cement plate may be used as a base material (paragraph [0037]). Extruded cement boards are obtained by extruding cement molding materials with an extrusion molding machine, providing decorative joints (hereinafter, simply referred to as "joints", including vertical joints and horizontal joints) with rollers, and then curing and curing. Be done. On the outer circumference of the roller, a convex portion for horizontal joints is provided in the circumferential direction, and a convex portion for vertical joints is provided in the direction of rotation axis.
しかしながら、ローラーで目地を設けながら押出成形を行う場合、例えば、押出成形セメント板の幅方向に設計上延びる目地（縦目地）が幅方向に対して若干傾斜して延びることがある。 However, when extrusion molding is performed while providing joints with rollers, for example, joints (vertical joints) that extend in the width direction of the extruded cement plate by design may extend slightly inclined with respect to the width direction.
本発明者は、上記の原因の１つは、セメント成形材料を押し出す場合の幅方向における流速の違いにあると考える。すなわち、押出成形機によりセメント成形材料を所定幅で押し出す場合、幅方向（押し出す方向に対して垂直な方向）における中央部の流れが、幅方向における両端部の流れに比べて速くなりやすい。つまり、所定幅のセメント成形材料の幅方向の中央部から両端部に向かうほど流速が遅くなる。これに起因して特に押出成形セメント板の幅方向における目地が押出成形セメント板の幅方向に対して若干傾斜して見えるおそれがある。 The present inventor considers that one of the above causes is the difference in the flow velocity in the width direction when the cement molding material is extruded. That is, when the cement molding material is extruded with a predetermined width by an extrusion molding machine, the flow at the central portion in the width direction (direction perpendicular to the extruding direction) tends to be faster than the flow at both ends in the width direction. That is, the flow velocity becomes slower from the central portion in the width direction of the cement molding material having a predetermined width toward both ends. Due to this, the joints in the width direction of the extruded cement board may appear to be slightly inclined with respect to the width direction of the extruded cement board.
押出成形セメント板が単色で塗装されている場合には、目地が傾斜して見えることはあまりないが、押出成形セメント板が２色以上で塗装されている場合、特に目地の色と凸部表面の色とが異なる色の場合には、目地の傾斜が分かりやすくなる。 When the extruded cement board is painted in a single color, the joints do not often appear to be tilted, but when the extruded cement board is painted in two or more colors, especially the joint color and convex surface. If the color is different from the color of, the inclination of the joint becomes easy to understand.
本発明の目的は、２色以上で塗装されても目地の傾斜が目立ちにくい建築板を提供することにある。 An object of the present invention is to provide a building board in which the inclination of joints is inconspicuous even when painted in two or more colors.
本発明の一態様に係る建築板は、平板部と、前記平板部に設けられた複数の凸部と、を備える。前記複数の凸部は、直交する目地で区画されている。前記複数の凸部の少なくとも一部の凸部は、意匠面と、前記意匠面に隣接する側面と、を含む。前記意匠面と前記側面との境界線は、少なくとも直線状の境界線を含む。前記直線状の境界線は、前記直線状の境界線と隣接する前記目地に対して、非平行となる区間を含む。前記意匠面と、前記意匠面以外の部分とが塗り分けられている。 The building board according to one aspect of the present invention includes a flat plate portion and a plurality of convex portions provided on the flat plate portion. The plurality of convex portions are partitioned by orthogonal joints. At least a part of the convex portion of the plurality of convex portions includes a design surface and a side surface adjacent to the design surface. The boundary line between the design surface and the side surface includes at least a linear boundary line. The linear boundary line includes a section that is non-parallel to the joint adjacent to the linear boundary line. The design surface and a portion other than the design surface are painted separately.
本発明によれば、２色以上で塗装されても目地の傾斜が目立ちにくい。 According to the present invention, the inclination of the joint is not noticeable even if it is painted with two or more colors.
１．概要
本実施形態に係る建築板１は、押出成形機によりセメント成形材料を押し出しながら、目地形成用ローラーで目地６を設け、所定の大きさに切断し、養生硬化した後、塗装用ローラーで２色以上に塗装することにより得られる。
1. 1. Outline The building board 1 according to the present embodiment is provided with joints 6 by a joint forming roller while extruding a cement molding material by an extrusion molding machine, cut to a predetermined size, cured and cured, and then 2 by a coating roller. Obtained by painting more than the color.
本実施形態に係る建築板１の特徴の１つは、図１に示すように、直線状の境界線４１が、直線状の境界線４１と隣接する目地６に対して、非平行となる区間４１１を含んでいる点である。このように、非平行となる区間４１１を意図的に含ませることによって、非平行となる区間４１１を全く含まない場合に比べて、目地６の傾斜を目立ちにくくすることができる。 One of the features of the building board 1 according to the present embodiment is that, as shown in FIG. 1, the linear boundary line 41 is non-parallel to the joint 6 adjacent to the linear boundary line 41. It is a point that includes 411. By intentionally including the non-parallel section 411 in this way, the inclination of the joint 6 can be made less noticeable as compared with the case where the non-parallel section 411 is not included at all.
２．詳細
図１に本実施形態に係る建築板１を示す。図１中のＤ１及びＤ２は直交する２方向を示す。Ｄ１は、建築板１の縦方向（押出成形の幅方向）を示し、Ｄ２は、建築板１の横方向（押出成形の押出方向）を示す。
2. 2. Detailed FIG. 1 shows the building board 1 according to the present embodiment. D1 and D2 in FIG. 1 indicate two orthogonal directions. D1 indicates the vertical direction of the building board 1 (width direction of extrusion molding), and D2 indicates the horizontal direction of the building board 1 (extrusion direction of extrusion molding).
建築板１は、外壁材等の外装材として用いられ、矩形状に形成されている。図１は、建築板１の屋外側を向く面の要部を示す。以下、この面を屋外から見た状態を平面視という場合がある。そして、上記の「非平行」とは、建築板１を平面視して境界線４１の延びる方向と隣接する目地６の延びる方向とが交差することをいう。 The building board 1 is used as an exterior material such as an outer wall material, and is formed in a rectangular shape. FIG. 1 shows a main part of the surface of the building board 1 facing the outdoor side. Hereinafter, the state in which this surface is viewed from the outside may be referred to as a plan view. The above-mentioned "non-parallel" means that the extending direction of the boundary line 41 and the extending direction of the adjacent joint 6 intersect in a plan view of the building board 1.
建築板１は、例えばセメント成形材料で形成されている。セメント成形材料としては、例えば、セメント及び補強繊維を主成分とする材料等の公知の材料が使用可能であり、特に限定されない。 The building board 1 is made of, for example, a cement molding material. As the cement molding material, for example, a known material such as a material containing cement and reinforcing fibers as main components can be used, and the material is not particularly limited.
建築板１は、平板部２と、複数の凸部３と、を備える。複数の凸部３は、平板部２の表面に設けられている。平板部２と、複数の凸部３とは、一体に形成されている。 The building board 1 includes a flat plate portion 2 and a plurality of convex portions 3. The plurality of convex portions 3 are provided on the surface of the flat plate portion 2. The flat plate portion 2 and the plurality of convex portions 3 are integrally formed.
複数の凸部３は、直交する複数の目地６で区画されている。目地６は、縦目地６１と、横目地６２とを含む。縦目地６１は、建築板１の縦方向Ｄ１の目地であり、横目地６２は、建築板１の横方向Ｄ２の目地である。 The plurality of convex portions 3 are partitioned by a plurality of orthogonal joints 6. The joint 6 includes a vertical joint 61 and a horizontal joint 62. The vertical joint 61 is a joint in the vertical direction D1 of the building board 1, and the horizontal joint 62 is a joint in the horizontal direction D2 of the building board 1.
好ましくは、縦目地６１及び横目地６２の少なくともいずれかは、直線上に連なっていない。図１では、縦目地６１は、一本の直線上に連なっていない。横目地６２は、一本の直線上に連なっている。より具体的には、複数の横目地６２が縦方向に間隔をあけて互いにほぼ平行に延びており、各横目地６２は横方向全体にわたって直線上に連続して延びている。また、各横目地６２から横方向に間隔をあけて複数の縦目地６１が縦方向両側に延びている。そして、上記の「縦目地６１は、一本の直線上に連なっていない」とは、横目地６２から縦方向両側に延びる縦目地６１の横方向の位置が一致しないことをいう。このような目地配置によって、図１に示すように、複数の凸部３が横方向に直線上に並んで凸部列を構成し、この凸部列が縦方向に複数並んでいる。そして、縦方向に隣り合う凸部列において、一方の凸部列内の縦目地６１の横方向の位置と他方の凸部列内の縦目地６１の横方向の位置とが一致していない。ここで、「縦目地６１の横方向の位置」とは、縦目地６１の幅方向中心線の位置をいい、縦方向に隣り合う縦目地６１が横方向において一部重なる場合も含む。このように、縦目地６１が一本の直線上に連なっておらず、縦方向において分断されていることによって、一本の直線上に連なっている場合に比べて、縦目地６１の傾斜が更に目立ちにくくなる。 Preferably, at least one of the vertical joint 61 and the horizontal joint 62 is not connected in a straight line. In FIG. 1, the vertical joints 61 are not connected on a straight line. The horizontal joints 62 are connected on a straight line. More specifically, a plurality of horizontal joints 62 extend substantially parallel to each other at intervals in the vertical direction, and each horizontal joint 62 extends continuously in a straight line over the entire horizontal direction. Further, a plurality of vertical joints 61 extend from each horizontal joint 62 on both sides in the vertical direction at intervals in the horizontal direction. The above-mentioned "vertical joints 61 are not continuous on one straight line" means that the horizontal positions of the vertical joints 61 extending from the horizontal joints 62 to both sides in the vertical direction do not match. With such a joint arrangement, as shown in FIG. 1, a plurality of convex portions 3 are arranged in a straight line in the horizontal direction to form a convex portion row, and a plurality of the convex portion rows are arranged in the vertical direction. Then, in the convex row adjacent to each other in the vertical direction, the horizontal position of the vertical joint 61 in one convex row and the horizontal position of the vertical joint 61 in the other convex row do not match. Here, the "horizontal position of the vertical joint 61" refers to the position of the center line in the width direction of the vertical joint 61, and includes the case where the vertically adjacent vertical joints 61 partially overlap in the horizontal direction. As described above, since the vertical joints 61 are not connected on one straight line and are divided in the vertical direction, the inclination of the vertical joints 61 is further increased as compared with the case where the vertical joints 61 are connected on one straight line. It becomes less noticeable.
図示省略しているが、縦目地６１が一本の直線上に連なり、横目地６２が一本の直線上に連なっていなくてもよい。この場合には、横目地６２が一本の直線上に連なっていないことによって、一本の直線上に連なっている場合に比べて、横目地６２の傾斜が更に目立ちにくくなる。 Although not shown, the vertical joints 61 may be continuous on one straight line, and the horizontal joints 62 may not be continuous on one straight line. In this case, since the horizontal joints 62 are not connected on one straight line, the inclination of the horizontal joints 62 becomes less noticeable as compared with the case where the horizontal joints 62 are connected on one straight line.
同様に図示省略しているが、縦目地６１及び横目地６２の両方が一本の直線上に連なっていなくてもよい。この場合には、目地６の傾斜が更に目立ちにくくなる。なお、この場合には、複数の凸部３の各々の大きさ（平面視での大きさ）が異なり得る。 Similarly, although not shown, both the vertical joint 61 and the horizontal joint 62 do not have to be connected on one straight line. In this case, the inclination of the joint 6 becomes less noticeable. In this case, the size of each of the plurality of convex portions 3 (the size in a plan view) may be different.
複数の凸部３の少なくとも一部の凸部３は、意匠面３１と、側面３２と、を含む。意匠面３１は、矩形状の面である。図１では、意匠面３１を横長の矩形状に図示しているが、これには限定されない。意匠面３１には自然石等の様々なデザインが施されている。なお、意匠面３１と平板部２の表面との距離が目地６の深さに相当する。 At least a part of the convex portions 3 of the plurality of convex portions 3 includes the design surface 31 and the side surface 32. The design surface 31 is a rectangular surface. In FIG. 1, the design surface 31 is shown in a horizontally long rectangular shape, but the design surface 31 is not limited to this. Various designs such as natural stones are applied to the design surface 31. The distance between the design surface 31 and the surface of the flat plate portion 2 corresponds to the depth of the joint 6.
側面３２は、意匠面３１に隣接している。側面３２は、意匠面３１の周囲に位置する。図１では、側面３２は、意匠面３１の四辺に位置している。側面３２は、平板部２の表面（目地６の底面）に対して傾斜していてもよいし、垂直であってもよい。図１では、一部の側面３２は、目地６の底面に対して傾斜しており、傾斜面となっている。なお、目地６の幅は、隣り合う凸部３，３において、平板部２の表面と側面３２との境界線同士の距離に相当する。 The side surface 32 is adjacent to the design surface 31. The side surface 32 is located around the design surface 31. In FIG. 1, the side surface 32 is located on the four sides of the design surface 31. The side surface 32 may be inclined with respect to the surface of the flat plate portion 2 (bottom surface of the joint 6) or may be perpendicular to the surface. In FIG. 1, a part of the side surface 32 is inclined with respect to the bottom surface of the joint 6, and is an inclined surface. The width of the joint 6 corresponds to the distance between the boundary lines between the surface and the side surface 32 of the flat plate portion 2 in the adjacent convex portions 3 and 3.
複数の凸部３の少なくとも一部の凸部３について、意匠面３１と側面３２との境界線４は、少なくとも直線状の境界線４１を含む。なお、側面３２の傾斜角度、すなわち、側面３２とそれに隣接する目地６の底面とのなす角度は、０度より大きく９０度未満が好ましく、より好ましくは２０度以上７０度以下である。 For at least a part of the convex portions 3 of the plurality of convex portions 3, the boundary line 4 between the design surface 31 and the side surface 32 includes at least a linear boundary line 41. The inclination angle of the side surface 32, that is, the angle formed by the side surface 32 and the bottom surface of the joint 6 adjacent thereto is preferably larger than 0 degrees and less than 90 degrees, and more preferably 20 degrees or more and 70 degrees or less.
意匠面３１の部分と、意匠面３１以外の部分とは塗り分けられている。意匠面３１以外の部分とは、主として目地６の底面であり、側面３２も含み得る。建築板１が単色で塗装されると、目地６が傾斜して見えることはあまりないが、本実施形態では、建築板１が２色以上で塗装されても、次のようにして目地６の傾斜を目立ちにくくしている。 The portion of the design surface 31 and the portion other than the design surface 31 are painted separately. The portion other than the design surface 31 is mainly the bottom surface of the joint 6, and may include the side surface 32. When the building board 1 is painted in a single color, the joint 6 does not often appear to be tilted, but in the present embodiment, even if the building board 1 is painted in two or more colors, the joint 6 is painted as follows. The slope is less noticeable.
すなわち、本実施形態に係る建築板１においては、直線状の境界線４１は、直線状の境界線４１と隣接する目地６に対して、非平行となる区間４１１を含む。直線状の境界線４１の全体が非平行となる区間４１１でもよい。このように、非平行となる区間４１１を意図的に含ませることによって、非平行となる区間４１１を全く含まない場合に比べて、目地６の傾斜を目立ちにくくすることができる。図１では、縦目地６１の傾斜が目立ちにくくなっている。 That is, in the building board 1 according to the present embodiment, the linear boundary line 41 includes a section 411 that is non-parallel to the joint 6 adjacent to the linear boundary line 41. The section 411 in which the entire linear boundary line 41 is non-parallel may be used. By intentionally including the non-parallel section 411 in this way, the inclination of the joint 6 can be made less noticeable as compared with the case where the non-parallel section 411 is not included at all. In FIG. 1, the inclination of the vertical joint 61 is less noticeable.
好ましくは、隣り合う凸部３，３の直線状の境界線４１，４１同士が非平行である。例えば、図１では、隣り合う凸部３，３について、両者の非平行となる区間４１１，４１１同士が非平行となっている。これにより、目地６の傾斜が更に目立ちにくくなる。 Preferably, the linear boundary lines 41, 41 of the adjacent convex portions 3, 3 are non-parallel to each other. For example, in FIG. 1, with respect to adjacent convex portions 3 and 3, the sections 411 and 411 that are non-parallel to each other are non-parallel. As a result, the inclination of the joint 6 becomes less noticeable.
また好ましくは、直線状の境界線４１は、直線状の境界線４１と隣接する目地６に対して、非平行となる区間４１１及び平行となる区間４１２を含む。これにより、目地６の傾斜が更に目立ちにくくなる。 Further, preferably, the linear boundary line 41 includes a section 411 that is non-parallel and a section 412 that is parallel to the joint 6 adjacent to the linear boundary line 41. As a result, the inclination of the joint 6 becomes less noticeable.
さらに好ましくは、非平行となる区間４１１において、直線状の境界線４１と、直線状の境界線４１と隣接する目地６とのなす角度θ（図１参照）が、目地６の延びる方向に対して、−３度以上＋３度以下の範囲内である。角度θが上記の範囲内であることで、目地６の傾斜が更に目立ちにくくなる。 More preferably, in the non-parallel section 411, the angle θ (see FIG. 1) formed by the linear boundary line 41 and the joint 6 adjacent to the linear boundary line 41 is relative to the extending direction of the joint 6. It is within the range of -3 degrees or more and +3 degrees or less. When the angle θ is within the above range, the inclination of the joint 6 becomes less noticeable.
上記のような隣接する目地６に対して非平行な境界線４１を有する凸部３は、建築板１の縦方向中央部よりも両端部にあるのが好ましい。そして、非平行な境界線４１が縦方向外側ほど多く且つランダムにあるのが好ましい。この場合、押出方向の流速が縦方向外側ほど遅くなり、縦目地が傾斜して形成されており、この傾斜を目立ち難くするために縦方向外側ほど非平行な境界線４１が形成されているのが好ましいためである。 It is preferable that the convex portions 3 having the boundary lines 41 non-parallel to the adjacent joints 6 as described above are located at both ends of the building board 1 rather than the central portion in the vertical direction. Then, it is preferable that the non-parallel boundary lines 41 are more and more randomly toward the outside in the vertical direction. In this case, the flow velocity in the extrusion direction becomes slower toward the outside in the vertical direction, and the vertical joints are formed with an inclination, and in order to make this inclination less noticeable, a non-parallel boundary line 41 is formed toward the outside in the vertical direction. Is preferable.
なお、非平行な境界線４１を有する凸部３の配置は、上記に限らず、押出方向における流速に基づいて定まる。例えば、押出機のスクリューが水平に２軸配置されている場合、これら２軸から離れるほど流速が遅くなるため、この２軸から離れた位置ほど非平行な境界線４１を有する凸部３が多く配置される。 The arrangement of the convex portion 3 having the non-parallel boundary line 41 is not limited to the above, and is determined based on the flow velocity in the extrusion direction. For example, when the screws of the extruder are arranged horizontally in two shafts, the flow velocity becomes slower as the distance from these two shafts increases, so that the distance from these two shafts increases the number of convex portions 3 having non-parallel boundary lines 41. Be placed.
３．変形例
上記実施形態では、凸部３が平面視で横方向に長い矩形状をなしているが、これに限定されず、平面視多角形状をなしていてもよい。
3. 3. Modification Example In the above embodiment, the convex portion 3 has a rectangular shape that is long in the horizontal direction in a plan view, but the present invention is not limited to this, and a polygonal shape in a plan view may be formed.
また、上記実施形態では、側面３２が三角形状をなしているが、これに限定されず、高矩形状（四角形、五角形など）であってもよい。 Further, in the above embodiment, the side surface 32 has a triangular shape, but the present invention is not limited to this, and a high rectangular shape (quadrangle, pentagon, etc.) may be used.
