Description

  The present invention relates to a building board having a design pattern and forming a wall surface of a house or the like.

  It is required that a high designability be imparted to a wall surface such as an outer wall of a house. As one of the methods of imparting design properties to the outer wall, for example, there is a method of applying a concavo-convex pattern such as a pattern or joint on the surface, or applying a cement or other building board to a wall with coloring or painting applied to the wall. is there. When such an architectural board is used to form the outer wall, for example, a wide variety of designs such as brickwork, masonry, tiling, and wood boarding can be applied to the outer wall, giving a profound feeling and luxury to the outer wall of a house, etc. be able to. In addition, in recent years, it has been required to provide design properties on the outer walls of buildings such as recreational facilities as well as houses, etc. In addition, an outer wall having an appearance that gives a feeling that the pattern swings is also desired. When it is visually recognized that the pattern of the outer wall is swaying in this way, even if the building board is made of, for example, a cement-based material, it is difficult to receive an impression of such a material itself. Therefore, a certain unified appearance can be given to the outer wall regardless of the material type of the building board. Furthermore, when constructing the outer wall by matching the side end surfaces of the building board, even if the abutted part is displaced, if it is visually recognized as if the entire pattern is shaking, such misalignment Can be made inconspicuous.

  As a concrete example of a building board capable of imparting design properties, in a cement-based building board in which a concave portion and a convex portion are formed, a coating film having a color tone different from that of the convex portion is formed in the concave portion, and the coating film on the concave portion fluctuates. A construction board formed with a pattern (a wavy pattern) has been proposed (see, for example, Patent Document 1).

JP 2007-705 A

  However, in the above building board, it is possible to impart a natural and three-dimensional design to the outer wall, but in the adjacent building board, when the misalignment between these side end faces occurs, Deviation may be conspicuous, causing a decrease in design.

  The present invention has been made in view of the above points, and in forming a wall surface of a house or the like, even if a positional deviation occurs between adjacent base materials, the positional deviation can be made inconspicuous. It aims at providing the building board which can provide high designability to wall surfaces, such as a house.

In the building board according to the present invention, a plurality of substantially rectangular convex portions are arranged at a predetermined interval on a substantially flat substrate surface, and a concave groove portion is formed between the adjacent convex portions. And a grooved plate, each of which is a building board provided with a plurality of rectangular rod-shaped linear patterns, the extending direction of the linear pattern provided on the convex part, and the concave groove part up direction der substantially perpendicular to each other and the extending direction of the linear pattern, in a direction perpendicular to the stretching direction of the linear pattern, the linear patterns each other adjacent to each other substantially parallel to face each other while a predetermined gap Are arranged, and the arrangement in the extending direction of the linear pattern is alternately shifted in a direction orthogonal to the extending direction of the linear pattern .

Moreover, in this invention, it is preferable that the said convex part is formed in elongate, and the said linear handle currently arranged in the said concave groove part is extended | stretched along the elongate direction of the said convex part.

Further, in the present invention, in the plurality of linear patterns arranged in the extending direction of the linear pattern, the linear patterns located on both sides of one linear pattern are positioned on the same straight line. Is preferred.

  According to the building board of the present invention, the linear patterns are arranged while the linear patterns are formed by extending in the directions substantially orthogonal to each other on the convex portions and the concave groove portions on the surface. It can be visually recognized as if the pattern to be formed is shaking. Therefore, when a wall surface of a house or the like is formed with the building board of the present invention, it is possible to impart an excellent design property that has not been found in the past to the wall surface. Moreover, when constructing a wall surface of a house or the like while sequentially laminating the building boards of the present invention, even if adjacent building boards are displaced from each other, the positional deviation can be made inconspicuous.

Furthermore, the convex part 2 and the concave groove part 3 are provided with a plurality of linear patterns 5 arranged, and by these linear patterns 5, the pattern is attached to the surface of the substrate 1. ing. Hereinafter, the building board A of the present invention will be described in detail with reference to FIG.

  FIG.1 (b) shows an example of the base material 1 for obtaining the building board A of this invention, and has shown the one part top view. Specifically, the substrate 1 shown in FIG. 1B shows a state before the linear pattern 5 is attached to the building board A.

  Although the shape of the base material 1 is not particularly limited, it is a rectangular shape such as a rectangle or a square if the building board A is sequentially attached and fixed to the wall to form a wall surface such as an outer wall. Can be suitably used. Although the dimension of the base material 1 is not specifically limited, For example, when formed in the substantially rectangular shape, a vertical dimension can be 300-900 mm and a horizontal dimension can be 900-3000 mm. The vertical and horizontal directions in this case are the same as the vertical and horizontal directions with respect to the front view of the wall base to which the building board A is attached.

  A plurality of convex portions 2 are formed on one surface of the substrate 1. In addition, in this specification, the surface in which the convex part 2 is formed is made into the surface of the base material 1. FIG. The plurality of convex portions 2 are all provided so as to protrude upward from the surface of the substrate 1.

  In the embodiment of FIG. 1B, the convex portion 2 is formed in a substantially rectangular shape in plan view. Then, the convex portion 2 having a substantially rectangular shape in a substantially plan view is formed so as to extend in the direction from the one end side of the base material 1 to the other end side (the lateral direction of the base material 1 in the drawing). 1 is provided over substantially the entire length. Furthermore, a plurality of the convex portions 2 are arranged over substantially the entire length of the base material 1 while leaving a predetermined interval in a direction substantially perpendicular to the extending direction (the longitudinal direction of the base material 1 in the drawing). Is provided. In this case, the adjacent convex portions 2 and 2 are arranged so that the long sides of the convex portions 2 face each other, and the plurality of convex portions 2 are all arranged substantially in parallel.

  The adjacent protrusions 2 and 2 may be equally spaced or may be arranged at different intervals, but when a wall surface of a house or the like is formed, a sense of unity appears in the wall pattern. And it is preferable that it is equally spaced. For the same reason, it is preferable that all of the plurality of convex portions 2 have substantially the same size.

  On the other hand, a substantially flat concave groove portion 3 is formed between the adjacent convex portions 2 and 2 along the long side direction of the convex portion 2, and is provided over substantially the entire length of the substrate 1. . Moreover, in the base material 1 shown in FIG.1 (b), the ditch | groove part 3 is formed not only between the adjacent convex parts 2 and 2 but the outer end part whole periphery of the base material 1 surface.

  As described above, in the base material 1 shown in FIG. 1B, the convex portion 2 and the concave groove portion 3 extend over substantially the entire length in one direction of the base material 1 from one end to the other end of the base material 1. Are provided parallel to each other. And the convex part 2 and the groove part 3 are alternately formed in the base-material 1 surface in the direction orthogonal to the extending | stretching direction of the convex part 2. As shown in FIG. That is, as shown in FIG. 2, the convex portions 2 and the concave groove portions 3 are alternately formed on the surface of the base material 1 to form a substantially wave-shaped cross section. FIG. 2 shows a cross section of the base material 1 from the longitudinal direction of the convex portion 2. By forming the convex portion 2 and the concave groove portion 3 on the surface of the base material 1 as described above, a so-called border pattern is formed on the surface of the base material 1.

  The base material 1 used by this invention is not restricted to the form of FIG.1 (b), For example, the both-sides edge part (or at least one side edge part) in the direction orthogonal to the extending | stretching direction of the convex part 2 of the base material 1 ), The convex portion 2 may be formed instead of the concave groove portion 3. Moreover, the convex part 2 may be provided over the full length of the base material 1. FIG.

  As shown in FIGS. 1 and 2, the peripheral side surface 2 a of the convex portion 2 may be formed to have an inclined surface toward the surface of the base material 1, or the peripheral side surface 2 a is not inclined and is It may be formed so as to hang down from the surface of one. Moreover, the top surface of the convex part 2 is normally formed flat so that a linear pattern may be easily attached.

  The height of the convex part 2 (the length from the back surface side end of the base material 1 to the top of the convex part 2) and the length from the back surface side end part of the base material 1 to the concave groove part 3 surface are particularly limited. It is not a thing. Moreover, what is necessary is just to make all the some convex parts 2 form in the same height.

  Next, the linear handle 5 attached to the base material 1 shown in FIG.

  As shown in FIG. 1A, a plurality of linear patterns 5 are provided (drawn) on each of the convex portion 2 and the concave groove portion 3 (see also FIG. 5 for reference). .

  The linear pattern 5 is not particularly limited, such as a substantially linear shape, a curved shape such as a wave shape or an arc shape, a polygonal line shape, or a linear shape formed by combining these, and depending on the target pattern What is necessary is just to select suitably. In particular, the linear handle 5 is preferably formed in the shape of a square bar having a long length and a short length as in the embodiment of FIG. 1, and in this case, a wall surface is formed by the building board A as described later. In this case, the pattern of the wall surface is easily shaken and visible, and an illusion effect is easily provided.

  The linear pattern 5 attached to the convex part 2 (hereinafter sometimes referred to as “convex linear pattern 51”) is the extending direction, that is, the direction extending from one end of the linear pattern 5 toward the other end. Are arranged so as to all face the same direction. In this case, a sense of unity occurs in the design properties of the building board A, and the design properties tend to be high. In addition, the extending | stretching direction of the linear handle 5 in case the linear handle 5 is curvilinear means the direction where the straight line at the time of connecting one end and the other end of the linear handle 5 with the straight line extends.

  A plurality of the convex part linear patterns 51 are arranged on the top surface of the convex part 2, but when the peripheral side surface 2 a of the convex part 2 forms an inclined surface, the peripheral side surface 2 a May be arranged with the convex linear pattern 51 attached thereto. The plurality of convex part linear patterns 51 may be provided so as to be evenly arranged over substantially the entire top surface of the convex part 2 (almost the entire surface of the inclined surface when it is also attached to the inclined surface). In this case, the pattern on the wall is swayed and becomes easier to see.

  On the other hand, the linear pattern 5 attached to the concave groove portion 3 (hereinafter, also referred to as “the concave groove portion linear pattern 52”) is the extending direction of the concave groove portion linear pattern 52 in the same manner as the convex linear pattern 51. Can be arranged so that they all face the same direction. What is necessary is just to make it attach | subject the some ditch | groove part linear pattern 52 over the substantially whole surface of the ditch | groove part 3. FIG.

  And in the building board A of this invention, each is formed so that the extending | stretching direction of the convex part linear pattern 51 and the extending | stretching direction of the ditch | groove part linear pattern 52 may become a direction substantially orthogonal to each other. Specifically, the angle formed between the extending direction of the convex linear pattern 51 and the extending direction of the concave groove linear pattern 52 is 60 to 120 °. Thus, by providing the convex part linear pattern 51 and the concave groove part linear pattern 52, when the construction board A is constructed and the wall surface is formed, the pattern of the construction board A by the linear pattern 5 swings. Can cause an illusionary effect on the viewer. As a result, the pattern on the wall surface is easily noticeable, and a novel design can be applied to the wall surface. Further, even when the abutting portion 20 between the side end surfaces of the building board A is displaced when forming the wall surface, and the misalignment due to the concave groove portion 3 occurs, the misalignment is not conspicuous due to the sense that the pattern swings. Thus, an excellent design property can be brought to the wall surface.

  When the convex portion 2 is formed in a rectangular shape in a plan view, as in the embodiment of FIG. 1 (or also refer to the embodiment of FIG. 5), a plurality of recessed groove portion linear handles 52 are stretched. The direction is preferably the same as the long side direction of the convex portion 2 (that is, the extending direction of the convex portion 2). In this case, all of the plurality of convex part linear patterns 51 are arranged so that the extending direction thereof is parallel to the short side of the convex part 2. In this way, when the wall surface is formed with the building board A arranged so that the extending direction of the concave groove portion linear pattern 52 is in the same direction as the long side direction of the convex portion 2, the pattern on the wall surface is more swayed. It will be easy to see with a sense of being. Therefore, the design property excellent in the building board A can be provided, and the said position shift can be made more inconspicuous.

  In the present invention, not only the butted portion 20 between the side end surfaces of the building board A positioned on the left and right sides as described above, for example, in the building board A in which the real part is formed on the upper and lower or left and right end faces, The same effect as described above can also be obtained in a joint formed by A being phased (bonded).

  Here, the state of the arrangement of the plurality of linear patterns 5 will be further described in detail.

  In the embodiment of FIG. 1, the linear patterns 5, 5 that are adjacent in the direction substantially orthogonal to the extending direction of the linear pattern 5 are arranged to face each other substantially in parallel with a predetermined interval. On the other hand, the linear patterns 5 and 5 that are adjacent (or close to each other) in the extending direction of the linear pattern 5 are not arranged in the same straight line but are orthogonal to the extending direction of the linear pattern 5. It is shifted and arranged. That is, the linear handle 5 and the linear handle 5 located close to the side edge of the linear handle 5 are not collinear with each other and are arranged in a shifted state. The above-mentioned “linear patterns 5 and 5 adjacent to each other in the extending direction of the linear pattern 5” means a line that is closest to the linear pattern 5 in the extending direction of the linear pattern 5. The positional relationship with the pattern 5 is shown.

  In addition, when three or more linear patterns 5 are arranged along the extending direction of the linear patterns 5, the linear patterns 5 and 5 located at both ends of one linear pattern 5 are substantially the same. They are arranged in a straight line. That is, the arrangement of the linear patterns 5 in the extending direction is alternately shifted in the direction orthogonal to the extending direction of the linear patterns 5 as in the arrangement of the groove-shaped linear patterns 52 shown in FIG. Are arranged along the stretching direction.

  When the linear pattern 5 is arranged as described above, the linear pattern 5 attached to the building board A is formed in a so-called checkered pattern shape (or a check pattern shape) as a whole. It will be. That is, in FIG. 1 (or FIG. 5), when one linear pattern 5 is regarded as a rectangle, each linear pattern 5 in a rectangular shape is regularly spaced at the same size as the linear pattern 5 in the vertical and horizontal directions. Will be arranged.

  In this way, when the linear pattern 5 is applied in a checkered pattern, when the wall surface is formed with such a building board A, the sense that the pattern on the wall surface is swayed becomes stronger, which is larger for those who see the pattern. An illusion can be caused and a more conspicuous appearance can be obtained. In addition, depending on the angle and distance between the point where the wall is viewed and the wall, a different pattern is visually recognized, and a pattern having a perspective effect can be obtained. In addition, the feeling of the wall pattern appearing to swing is further enhanced, making it difficult to receive the impression of the material of the building board A itself, and providing a certain appearance pattern regardless of the type of material of the building board A. Will be able to. In addition, even when the side wall surfaces of the building board A are shifted and abutted when the wall surface is formed and a joint shift occurs due to the concave groove portion 3, the shift becomes inconspicuous, and the wall surface has excellent design properties. Can do. Furthermore, when the linear pattern 5 is applied in a checkered pattern as described above, the color of the linear pattern 5 is alternately colored as, for example, white and black. As a result, the above-described effects are more remarkably exhibited.

  In the building board A of the present invention, the plurality of convex line patterns 51 formed are all the same shape, that is, are formed with the same length and the same thickness, and a plurality of concaves are formed. It is preferable that all the groove part linear patterns 52 are also formed in the same shape, that is, the same length and the same thickness. For example, the length of the convex part linear pattern 51 can be about half to one third of the length of the short side of the convex part 2, and the concave groove part linear pattern 52 has the same length. be able to.

  Furthermore, as in the embodiment of FIG. 1, it is preferable that both the convex portion linear handle 51 and the concave groove portion linear handle 52 are regularly arranged at equal intervals. In such a case, the pattern formed on the wall surface becomes beautiful as a whole, and a sense of unity tends to occur, and higher design properties can be brought about.

  In the building board A of the present invention, the length and thickness of the plurality of linear patterns 5 can be appropriately set according to the dimensions of the building board A and the dimensions of the convex portion 2 and the concave groove portion 3. Some linear patterns 5 may be mixed in part with different lengths and thicknesses.

  The embodiment shown in FIG. 3 is an example thereof, and in this embodiment, the thickness of the concave groove portion linear pattern 52 is made different (see also FIG. 6 for reference). Here, the thickness of the concave groove portion linear pattern 52 refers to the length in the direction orthogonal to the extending direction of the concave groove portion linear pattern 52, that is, the short side length of the concave groove portion linear pattern 52).

  Specifically, in the embodiment of FIG. 3, in the concave groove portion 3 formed along the long side direction of the convex portion 2, the extending direction of the concave groove portion linear handle 52 (the concave groove portion linear handle 52 The groove patterns 52 adjacent to each other in the long side direction are formed to have the same thickness. On the other hand, the groove groove linear patterns 52 adjacent in the direction orthogonal to the extending direction of the groove groove linear pattern 52 (the short side direction of the groove groove linear pattern 52) are formed with different thicknesses. That is, in the concave groove part linear pattern 52 arranged while forming a plurality of rows along the long side direction of the convex part 2, the concave groove part linear pattern 52 is different so that the thickness of the concave groove part linear pattern 52 is different for each column. The grooved linear pattern 52 is formed. What is necessary is just to form the thickness of the concave groove part linear pattern 52 of each row | line | column to appropriate thickness. Further, for example, when the concave groove portion linear patterns 52 are arranged in the concave groove portions 3 along the long side direction of the convex portions 2, the thickness of the concave groove portion linear patterns 52 in both ends of the rows is the same. Only the thickness of the central groove 52 linear pattern 52 may be different, or all three rows may have different thicknesses. The same applies to the case where four or more rows of concave groove portion linear patterns 52 are arranged in the concave groove portion 3. Thus, although the thickness of the concave groove part linear pattern 52 differs for every row | line, the arrangement | sequence order may be different in the plurality of concave groove parts 3, respectively, and may be the same. The thickness of the concave groove portion linear pattern 52 is not particularly limited, and is appropriately selected as long as it is shorter than the width of the concave groove portion 3 (that is, the distance between the convex portions 2 and 2 adjacent in the short side direction of the convex portion 2). You can make it thick.

  As described above, even when the side end surfaces of the building board A are shifted and faced when the wall surface is formed with the building board A by changing the thickness of the grooved linear pattern 52 as described above, The positional deviation becomes inconspicuous, and an excellent design property can be brought about by the wall surface. In addition, even when the real part is formed on the upper and lower end surfaces or the left and right end surfaces of the building board A and the building boards A are joined to each other (phased), the same effect is obtained. Is.

  Of course, the base material 1 used in the building board A of the present invention is not limited to the one shown in FIG. For example, in the form of FIG. 1B, the elongated protrusion 1 is formed over the entire length of the base material 1 along the long side direction, but is not limited thereto. For example, as shown in FIG. 4, a plurality may be formed with a predetermined interval in the longitudinal direction. In short, in this case, the plurality of convex portions 2 are arranged at a predetermined interval, for example, at regular intervals, in the longitudinal direction (short side direction of the convex portion 2) and the lateral direction (long side direction of the convex portion 2) on the base material 1. It is formed by regular arrangement. And in such a base material 1, since the ditch | groove part 3 is formed between the some convex parts 2, the base material 1 is formed in a grid | lattice pattern shape. In addition, about another structure, it is the same as that of the base material shown in FIG.1 (b), and the linear handle 5 can also be provided with the structure similar to the above-mentioned. Moreover, in FIG. 4, each convex part 1 is formed in the elongate rectangular shape, However, A square-shaped thing may be sufficient.

  As described above, as the base material 1 in the present invention, a plurality of convex portions having a substantially rectangular shape in plan view are arranged on the surface with a predetermined interval, and the concave groove portion 3 is formed between the adjacent convex portions 2. Anything can be used. In this case, the interval between the adjacent convex portions 2 may not be equal, and each convex portion may not be aligned vertically and horizontally, but the design property of the wall surface is unlikely to deteriorate. The convex portions 2 are preferably arranged at equal intervals in the vertical direction and the horizontal direction, respectively. For the same reason, it is preferable that the plurality of convex portions 2 are formed in the same shape and size.

  In the building board A of the present invention, the color of the linear pattern 5 can be set to any color. In particular, in the case of the building board A of the present invention, in the adjacent protrusions 2 and 2, the protrusion linear pattern 51 attached to one protrusion 2 and the protrusion attached to the other protrusion 2. The partial linear pattern 51 preferably has different colors. In this case, in addition to the effect that the pattern appears to swing, the three-dimensional effect due to the uneven pattern on the surface of the building board A appears more remarkably, and a wall surface having a more practical design can be formed. On the other hand, the colors of the plurality of concave groove linear patterns 52 may be the same color, or may be different from the colors of the convex linear patterns 51.

  The color of the linear pattern 5 can be determined by, for example, a commercially available color difference meter, spectrocolorimeter, color difference meter, or the like, and the convex linear pattern attached to the adjacent convex portions 2 as described above. It can be determined that the 51 colors are different. At least the color of the convex part linear pattern 51 attached to the adjacent convex part 2 may be any color that is different to the extent that it can be visually recognized.

  The building board A (base material 1) of the present invention is composed of an inorganic material such as a ceramic base material or a metal base material, or is composed of an organic material such as a resin base material. It may be. Any inorganic board such as a flexible board, a calcium silicate board, a gypsum slag perlite board, a wood piece cement board, a precast concrete board, an ALC board, or a gypsum board can be used as long as it is made of an inorganic material. The ceramic base material can be produced by blending an inorganic filler, a fibrous material, or the like with a hydraulic glue used as a raw material for an inorganic hardened body, curing it, and curing it. Although it does not specifically limit as a hydraulic glue, For example, 1 type or multiple types of what was chosen from Portland cement, blast furnace cement, blast furnace slag, calcium silicate, gypsum, etc. can be used. In addition, as the inorganic filler, fly ash, microsilica, silica sand, etc., and as the fibrous material, inorganic fibers such as pulp and synthetic fibers, and metal fibers such as steel fibers are used alone or in combination. Can be used.

  The substrate 1 may be formed into a desired shape by a method such as extrusion molding, cast molding, papermaking molding, or press molding. Moreover, if the metal mold | die to be used is selected suitably according to the shape of the uneven | corrugated pattern (convex part 2 and the concave groove part 3) formed in the surface of the base material 1, for example, the uneven | corrugated pattern as shown in FIG.1 (b) The base material 1 which has can be obtained. After the base material 1 is obtained, autoclave curing, steam curing, and room temperature curing may be performed as necessary.

  In addition, the surface of the base material 1 obtained as described above is sealed with a solvent-based, water-soluble or emulsion-based sealer, and a layer (receiving layer) that promotes adsorption of ink or the like is further provided on the surface. For example, it can be formed using a water-based paint. In this case, for example, as described later, when the linear pattern 5 is formed by printing by inkjet coating or the like, the ink fixability is excellent, and the occurrence of ink bleeding or the like can be suppressed. A well-known method can be employ | adopted about the formation method of a seal | sticker and a receiving layer with the said sealer. The sealer used is not particularly limited, but acrylic or latex type sealers can be used. As the water-based paint for forming the receiving layer, an acrylic resin paint based on an acrylic emulsion or an acrylic silicon resin paint based on an acrylic silicon emulsion can be used. The water-based paint preferably contains at least one of extender pigments such as silica and alumina and a hygroscopic resin such as vinyl acetate. In this case, the fixing property of the ink can be improved, and the coloring property can also be improved.

  Although the formation method in particular to the base material 1 of the linear pattern 5 is not restrict | limited, For example, the linear pattern 5 can be attached | subjected to the base material 1 by printing by well-known inkjet coating etc. In addition, as a method for forming the linear pattern 5 on the base material 1, various methods such as roll coating, electrostatic coating, and powder coating can be employed.
