Description

  The present invention relates to building boards.

  Conventionally, ceramic siding boards, metal siding boards, ALC (Autoclaved Lightweight Aerated Concrete) boards and the like have been used as building boards that constitute the outer wall and inner wall of a building. This building board is usually a rectangular board. A plurality of building boards are pasted together and an outer wall and an inner wall of a building are constituted. The surface of this building board is often provided with various uneven shapes for the purpose of enhancing the design. For example, Patent Document 1 discloses a building board having a plurality of convex portions defined on the surface by vertical joints and horizontal joints. This building board exhibits excellent design, with long vertical joints not noticeable.

  Moreover, when comprising the outer wall and inner wall of a building, sticking the member of the cross-sectional L-shape called an exit corner may be performed to a corner. In order to unify the appearance of the wall surface, as described in Patent Document 2, after the construction board is cut, the construction board is cut so as to form an L-shaped cross section, and the appearance corner panel is formed. It is often manufactured. In this case, since the width of the required corner panels is different depending on the horizontal size of the building to be constructed, the building board is cut at various widths depending on the property.

  However, when the conventional building board divided by the vertical joint and the horizontal joint is cut in the longitudinal direction, depending on the cutting position, there may occur a part where the width of the convex part becomes extremely narrow. The convex part whose width is extremely narrow is easily noticeable, and the design of the joint region is impaired.

  This invention is made in view of the said conventional condition, Comprising: It aims at providing the building board which can exhibit the outstanding designability in the joining area | region of the panel for the corner produced by cutting a building board and manufacturing it. And

The building board according to the first aspect of the present invention includes a plurality of convex portions, which extend in a first direction and are located between the convex portions adjacent in a second direction orthogonal to the first direction to divide the convex portions. Extending in the second direction and extending in the first direction, and extending in the first direction, and extending in the second direction, and extending in the first direction; And a plurality of grooves dividing each of the convex portions into a plurality of blocks,
Each second joint is continuous from one end of the building board to the other end,
In each of the grooves, the depth from the surface is shallower than the depth of the first joint, and the width in the second direction is narrower than the width in the second direction of the first joint,
The blocks adjacent in the second direction have different surface patterns,
It is characterized in that the other first joint does not exist on the extension line which each of the first joints forms in the first direction, as long as it does not straddle at least three of the convex portions.

  In the building board of the first aspect, each convex portion is not only divided by the first joint extending in the first direction and the second joint extending in the second direction, but also the groove and block extending in the first direction It is divided into a plurality of blocks according to the surface shape. That is, the design in which a large number of small blocks are arranged is expressed by the first joint, the second joint, the groove, and the surface shape of the block.

  Each block arranged in the second direction is partitioned in the second direction by the first joint or groove. The groove is less noticeable than the first joint and the second joint because the depth from the surface is shallower than the depth of the first joint and the width in the second direction is narrower than the width in the second direction of the first joint . When the building board is cut in the first direction, even if a block adjacent to the groove in the second direction is cut in the groove and a block having an extremely narrow width in the second direction is formed, the groove is used as the first joint or the second joint It is less noticeable than the joints, so it appears that a block with an extremely narrow width in the second direction is connected to an adjacent block in the second direction via a groove, and a block with an extremely narrow width in the second direction is Inconspicuous and hard to lose design.

  In addition, if there is no straddling at least three convex portions on the extension line formed by the first joint in the first direction, the other first joint does not exist, so when cutting the building board in the first direction, A block having an extremely narrow width in two directions is difficult to be continuously formed in the first direction and is not noticeable, so the designability is not impaired.

  Furthermore, in the building board of the first aspect, each groove has a depth from the surface shallower than the depth of the first joint and a width in the second direction smaller than the width of the first joint. For this reason, the shade at the first and second joints is stronger than the shade of the ditch. The blocks adjacent in the second direction have different surface patterns, and if there is no straddle of at least three convex portions on the extension line formed by the first joints in the first direction, the other first joints are formed. Does not exist. For this reason, when seeing the whole construction board and the whole junction area where a plurality of construction boards were joined, strength and weakness can be made to the outline of a block, and excellent designability is exhibited.

  Therefore, the building board of the first aspect can exhibit excellent design in the joining area. For this reason, even if the panel for corner is manufactured by this building board, the building can exhibit excellent designability.

  As a second aspect of the present invention, there is no other first joint on an extension formed by each first joint in the first direction. When the building board of the second aspect is cut in the first direction, two or more blocks having extremely narrow widths in the second direction are not formed in the first direction and are hardly noticeable, so the design is not lost.

  As a third aspect of the present invention, each block has a ridge line block in which a ridge line partitioning the block is formed as a surface pattern. And each convex part has a ridgeline block, without making it adjacent to a 1st joint. In this case, the ridgeline block is more prominent than the block without the ridgeline because the shading is different from the ridgeline. If each convex portion has a ridge line block without being adjacent to the first joint, the block adjacent to the first joint and not having the ridge line is less noticeable when the entire construction board or the entire joint area is viewed. For this reason, even if the width in the second direction of the block adjacent to the first joint in the second direction is extremely narrowed by cutting, it is difficult to be noticeable. Also, it can be used as a design for construction boards.

  As a fourth aspect of the present invention, each protrusion has at least one ridge line block. In this case, since the conspicuous ridgeline block can be disposed on the entire construction board, the effect of the construction board of the third aspect becomes more remarkable.

  As a fifth aspect of the present invention, a plurality of ridge line blocks are provided separately in a direction intersecting the first direction and the second direction. In this case, since the conspicuous ridgeline block can be arranged without bias on the entire construction board, the effects of the construction boards of the third and fourth aspects become remarkable.

  As a sixth aspect of the present invention, the groove is a V-shaped groove having a V-shaped cross-sectional view or a trapezoidal groove having a trapezoidal shape in cross-sectional view. And the groove | channel which divides at least one block among the blocks which oppose on both sides of a 1st joint in a 2nd direction is a V-groove. In this case, since the V groove is less noticeable than the trapezoidal groove, the cut block is V groove even if the width of the block adjacent to the first joint in the second direction in the second direction is narrowed due to the cutting of the building board. It also appears as if it is connected to the adjacent block in the second direction via the two, and the cut block is less noticeable and less likely to impair the design.

  As a seventh aspect of the present invention, the second joint has a non-uniform width in the first direction. In this case, since the second joint is emphasized and the first joint and the groove become less noticeable, the width of the block adjacent to the first joint in the second direction in the second direction becomes narrow due to the cutting of the construction board Inconspicuous. In addition, when the raised corner panel is manufactured and made to be adjacent to the building board, the sense of incongruity is alleviated even if a shift of the second joint occurs.

  The building board of the present invention can exhibit excellent design in the joining area.

And each direction shown to each figure after FIG. 2 is made to respond | correspond to FIG. 1, and is displayed.

Embodiment 1
The building board of Embodiment 1 is the outer wall material 1 made of ceramic material including cement. As shown in FIG. 1, the outer wall material 1 has a substantially rectangular shape elongated in the left-right direction, and has, for example, a vertical dimension of 455 mm and a horizontal dimension of 3030 mm. In the first embodiment, the outer wall material 1 has the upper and lower end structure, and has a so-called real part (not shown) as a joint portion to be overlapped with the outer wall material 1 adjacent to the upper end edge and the lower end edge. ing.

  As shown in FIGS. 1 to 3, the outer wall material 1 extends in the longitudinal direction with a plurality of convex portions 3, a plurality of longitudinal joints 5 extending in the longitudinal direction, and six horizontal joints 7 extending in the lateral direction. And six grooves 9a to 9f for dividing each convex portion 3 into seven blocks 3a to 3g.

  In the first embodiment, the vertical direction, in other words, the vertical direction, corresponds to the first direction, and the horizontal direction, in other words, the horizontal direction, corresponds to the second direction.

  Each convex portion 3 has a substantially rectangular shape long in the left-right direction, and for example, the vertical dimension is 65 mm and the horizontal dimension is 303 mm. Each of the blocks 3a to 3g has a rectangular shape in which the longitudinal direction is slightly longer than the lateral direction, and for example, the longitudinal dimension is 65 mm and the lateral dimension is 42.8 mm or 44.5 mm.

  Each vertical joint 5 is located between the adjacent convex portions 3 in the lateral direction and divides the convex portions 3. As shown in FIGS. 5 and 6, each longitudinal joint 5 is inclined with respect to the joint bottom, and the inclination angle is, for example, 45 °, the width W1 in the lateral direction is, for example, 3 mm, and the depth D1 from the surface is, for example It is 3.5 mm. As shown in FIG. 1 and FIG. 2, no other vertical joint 5 exists on an extension formed by each vertical joint 5 in the vertical direction.

  Each horizontal joint 7 is located between the adjacent convex portions 3 in the longitudinal direction and divides the convex portions 3. Each horizontal joint 7 is inclined relative to the joint bottom as shown in FIG. 7, and the inclination angle is, for example, 45 °, the width W2 in the longitudinal direction is, for example, 3 to 5 mm, and the depth D2 from the surface is, for example, 3 It is said to be .5 mm. Each lateral joint 7 is continuous from the right end to the left end of the outer wall material 1. As shown in FIG. 2, the width W2 in the vertical direction of each horizontal joint 7 is not constant.

  The grooves 9a to 9f are located between the horizontally adjacent blocks 3a to 3g and define the blocks 3a to 3g. Each of the grooves 9a to 9f is, as shown in FIG. 5, a V-shaped groove 91 which is V-shaped in cross-sectional view or a trapezoidal groove 92 which is trapezoidal in cross-sectional view as shown in FIG. The depth D from the surface of each of the V-shaped groove 91 and the trapezoidal groove 92 is smaller than the depth D1 of the vertical joint 5. Further, the width W 3 in the lateral direction of each of the V-shaped groove 91 and the trapezoidal groove 92 is smaller than the width W 1 in the lateral direction of the vertical joint 5. Further, as shown in FIG. 2, the block 3a and the block 3g are opposed to each other across the vertical joint 5 in the lateral direction. The grooves 9a and 9f which define at least one of the blocks 3a and 3g are V-grooves 91.

  As shown in FIGS. 3 and 4, the blocks 3a to 3g adjacent in the lateral direction by the grooves 9a to 9f have different surface patterns. As shown in FIG. 4, at least one of the blocks 3 a to 3 g is a ridge line block 30 in which a ridge line R (see FIGS. 8 to 10) crossing the blocks is formed as a surface pattern.

  In the ridge line block 30, as shown in FIG. 8, one ridge line R linearly crosses in the vertical direction, or as shown in FIG. 9, one ridge line R is straight while being inclined with respect to the vertical direction. Or, as shown in FIG. 10, one ridge R is bent and crossed in the longitudinal direction. Although not shown, there is also a ridge line block 30 in which one ridge R is curved and traversed in the longitudinal direction.

  In FIG.1 and FIG.2, the ridgeline block 30 is hatched and shown. As shown in FIG. 1 and FIG. 2, each convex portion 3 has a ridge line block 30 without being adjacent to the vertical joint 5. Each convex portion 3 has one ridge line block 30. More specifically, in the outer wall material 1 of the first embodiment, as shown in FIGS. 1 and 8 to 10, the block 3 d at the center of each convex portion 3 is used as a ridge line block 30. As shown in FIG. 1, a plurality of ridge line blocks 30 are provided separately in the direction intersecting the longitudinal direction and the lateral direction.

  As shown in FIG. 1, it is assumed that the outer wall material 1 is joined to the left end (point A) or right end (point D) of another outer wall material 1. In this case, as shown in FIG. 11, the left end (point A) of a certain outer wall material 1 and the right end (point D) of another outer wall material 1 are joined without a sense of discomfort.

  Further, as shown in FIG. 1, when the outer wall material 1 is cut in the longitudinal direction at, for example, point C and joined to the left end (point A) of the other outer wall material 1, as shown in FIG. The left end (point A) of the material 1 and the outer wall material 1 cut at the point C are joined without discomfort. This is because, in the outer wall material 1, not only the respective convex portions 3 are divided by the longitudinally extending joints 5 extending in the longitudinal direction and the horizontally extending joints 7 extending in the transverse direction, but also the longitudinally extending grooves 9a to 9f and the blocks It is because it is divided into a plurality of blocks 3a to 3g by the surface shape of 3a to 3g.

  In detail, the blocks arranged in the lateral direction are divided in the lateral direction by the longitudinal joints 5 or the grooves 9a to 9f. The grooves 9a to 9f have a depth from the surface shallower than the depth of the vertical joint 5 and a width in the lateral direction 7 narrower than that in the horizontal direction of the vertical joint 5, so compared to the vertical joint 5 and the horizontal joint 7 It is hard to stand out. When the outer wall material 1 is cut in the longitudinal direction, even if the blocks 3a to 3g whose width in the lateral direction is extremely narrow are formed, the grooves 9a to 9f are less noticeable compared to the vertical joints 5 and the horizontal joints 7. The block whose width in the lateral direction is extremely narrow appears to be connected to the adjacent block in the lateral direction through the grooves 9a to 9f, and the block whose width in the lateral direction is extremely narrow is hardly noticeable.

  Particularly, in the outer wall material 1, the grooves 9a to 9f are the V groove 91 or the trapezoidal groove 92, and the V groove 91 divides at least one of the blocks 3a and 3g facing each other across the vertical joint 5 in the lateral direction. There is. Since the V groove 91 is less noticeable than the trapezoidal groove 92, the cut block is V even if the lateral width of the blocks 3a and 3g adjacent to the longitudinal joint 5 in the lateral direction becomes narrow due to the cutting of the outer wall material 1. It is easy to look as if it is connected to the adjacent block in the lateral direction via the groove 91, and the cut block is less noticeable.

  Moreover, since the other vertical joint 5 does not exist on the extension line which the vertical joint 5 forms in the vertical direction, when cutting the outer wall material 1 in the vertical direction, the block whose width in the horizontal direction is extremely narrow is in the vertical direction It is difficult to form continuously.

  Similarly, as shown in FIG. 1, when this outer wall material 1 is cut in the longitudinal direction at point B, for example, and joined with the right end (point D) of the other outer wall material 1, as shown in FIG. The right end (point D) of the outer wall material 1 and the outer wall material 1 cut at the point B are joined without a sense of discomfort.

  In particular, in this outer wall material 1, the depth D from the surface of each of the grooves 9 a to 9 f is smaller than the depth D 1 of the vertical joint 5 and the width W 3 in the lateral direction is narrower than the width W 1 of the vertical joint 5 The shadows at the vertical seam 5 and the horizontal seam 7 are stronger than the shadows of the grooves 9a to 9f. In addition, the blocks 3a to 3g adjacent in the lateral direction have different surface patterns, and the other longitudinal joint 5 does not exist on the extension line formed by the respective longitudinal joints 5 in the longitudinal direction. Moreover, when the whole joining area | region where several outer wall material 1 was joined is seen, strength can be made to the outline of block 3a-3g, and the outstanding designability is exhibited.

  Further, in the outer wall material 1, each convex portion 3 has the ridge line block 30 without being adjacent to the vertical joint 5. The ridge line block 30 is more prominent than the other blocks 3a to 3c and 3e to 3g because the shade differs with the ridgeline R as a boundary. For this reason, if each convex portion 3 has the ridge line block 30 without being adjacent to the vertical joint 5, the block 3a, 3g adjacent to the vertical joint 5 when looking at the entire outer wall material 1 or the entire joint area. Is not noticeable. Therefore, even if the width in the lateral direction of the blocks 3a to 3c and 3e to 3g adjacent to the vertical joint 5 is narrowed due to the cutting, the blocks 3a to 3c and 3e to 3g are less noticeable due to the presence of the ridgeline block 30. Moreover, the design of the outer wall material 1 can be stowed.

  Furthermore, in the outer wall material 1, since the plurality of ridge line blocks 30 are spaced apart in the direction intersecting the longitudinal direction and the lateral direction, the prominent ridge line blocks 30 can be arranged evenly over the entire outer wall material 1 There is.

  Furthermore, in the outer wall material 1, since the width W2 in the vertical direction of the horizontal joint 7 is not constant, the horizontal joint 7 is emphasized and the vertical joint 5 and the grooves 9a to 9f are less noticeable. For this reason, even if the width in the lateral direction of the blocks 3a and 3g adjacent to the vertical joint 5 in the lateral direction is reduced due to the cutting of the outer wall material 1, it is hard to be noticeable. In addition, when the raised corner panel is manufactured and made to be adjacent to the outer wall material 1, the discomfort is alleviated even if the lateral joint 7 is displaced.

  Therefore, this outer wall material 1 can exhibit excellent designability in the joining area. For this reason, even if it produces the panel for a corner by this outer wall material 1, a building can exhibit the outstanding designability.

Second Embodiment
The building board of Embodiment 2 is the outer wall material 12 shown in FIG. 14 and FIG. In the outer wall material 12, other vertical joints 5 do not exist on the extension lines formed by the vertical joints 5 in the longitudinal direction unless the three convex portions 3 are straddled. In other words, another vertical joint 5 is present on the extension line formed by the vertical joints 5 in the vertical direction if the three convex portions 3 are straddled. The other configuration is the same as that of the first embodiment.

  As in the case of the outer wall material 1 of the first embodiment, the outer wall material 12 is also less likely to be cut in the cut block, and less likely to impair the design. Moreover, when the outer wall material 1 is cut in the longitudinal direction, a block having an extremely narrow width in the lateral direction is difficult to be continuously formed in the longitudinal direction and is hardly noticeable, so the designability is not easily impaired.

In addition, the inclination angles of the first and second joints may be different.

  The number of grooves is not limited to six. Moreover, each convex part 3 may be divided into several blocks other than seven. Furthermore, the groove may be a U groove having a U-shaped cross section.

  With regard to the ridge line block, it is sufficient if the ridge line divides the inside of the block regardless of the first direction or the second direction. The ridge line may be bent or curved. The ridge line may be two or more, or may be branched. More preferably, the ridges cross the block in the first direction.

  The second joint may change the width in the first direction in units of convex portions, or may change the width in the first direction in units of blocks. Also, the width in the second direction of the first joint may be constant or may be changed. Furthermore, the width in the second direction of the groove may be changed, but all may be constant.

  The building board may be of an upper and lower joint structure having a real part superimposed on a building board adjacent to the upper end edge and the lower end edge, or a four-way joint structure having a real part at the four ends. And may not have a joint such as a real part. Moreover, a building board is not limited to an outer wall material, An inner wall material may be sufficient.
