Japanese Patent Laid-Open No. 10-219960 (see paragraph 0014, FIG. 6, etc.)

  By the way, some outer wall materials have irregularly provided protrusions on the surface. When such outer wall materials are arranged side by side and sealing is provided between adjacent outer wall materials as described above, a straight flat surface formed on the surface of the ceiling is formed among the uneven surfaces formed by a plurality of outer wall materials. May appear and give viewers a different texture. Moreover, the panel feeling is emphasized due to the conspicuous sealing, and there is a possibility that an inexpensive and easy impression is given to the exterior of the building.

  The present invention has been made in view of the above circumstances, and does not give a different texture to the viewer even if the seam is sealed, and does not give a cheap and easy impression to the exterior of the building and It aims at providing the construction structure of this building board.

  In order to achieve the above object, the present invention devises the shape of the convex portion provided on the surface of the building board.

  Specifically, the present invention is directed to a building board that is constructed in a predetermined direction through a ceiling in a predetermined direction, and has taken the following solution.

  That is, according to the first aspect of the present invention, a plurality of protrusions extending in the predetermined direction are provided on the surface so as to be aligned in an orthogonal direction orthogonal to the predetermined direction, and each protrusion is a plurality of protrusions aligned in the predetermined direction. The plurality of convex portions includes a parallel convex portion whose surface is a parallel surface parallel to the predetermined direction and the orthogonal direction, and an inclined surface whose surface is inclined in the predetermined direction. It is comprised by the inclination convex part which becomes.

  According to 1st invention, the surface of a building board is comprised by the protrusion from the parallel convex part which the surface consists of a parallel surface, and the inclined convex part which the surface consists of an inclined surface. Therefore, the surface of the ridge is formed so as to wave in the direction in which the building boards are arranged. Therefore, when building boards are arranged with a gap, the surface heights of the ridges located on both sides of the gap are not easily aligned. In such a state, when the gap is filled with a sealing material and leveled with a spatula or the like, a part of the surface of the ceiling is inclined in the width direction from the surface of one protrusion to the surface of the other protrusion. As a result, a part of the surface of the ceiling is inclined in the same manner as the surface of the inclined convex portion of the ridge.

  Furthermore, since the plurality of protrusions are arranged on the surface of the building board in a direction perpendicular to the direction in which the building boards are arranged, that is, in the direction in which the ceiling extends, the surface of the ceiling is not continuously formed with the same inclination. The inclination angle of the surface changes in the direction in which the ceiling extends. Therefore, it becomes difficult to distinguish between the surface of the ceiling and the surface of the building board, and the sealing can be made inconspicuous. As a result, it is difficult to give the viewer a different texture, and the appearance of the building is not given an inexpensive and easy impression.

  According to a second invention, in the first invention, the surface of the convex portion has a substantially quadrangular shape, and the sides aligned in the predetermined direction of the convex portion adjacent to the orthogonal direction are viewed from the orthogonal direction. The surface is shifted from the side aligned in the predetermined direction on the surface.

  According to the second aspect of the invention, since the convex portions are not easily aligned in the direction in which the ceiling extends, the inclination of the sealing surface is likely to change depending on the direction in which the ceiling extends. As a result, it becomes difficult to give the viewer a different texture. Moreover, even if the building board is cut in the direction in which the ceiling extends, that is, in the direction in which the ridges are arranged, it is difficult to align the protrusions in this direction, so that the conspicuousness of the ceiling can be reduced even if a cut product is constructed. .

  According to a third invention, in the first or second invention, the inclined convex portion includes a convex portion that is inclined so that the surface is raised to one side in the predetermined direction, and a surface is lowered to the one side in the predetermined direction. There are two types of convex portions, that is, an inclined convex portion.

  According to the third invention, since there are a plurality of types of inclined surfaces of the inclined convex portions, the surface heights of the protrusions on both sides of the ceiling are more difficult to align. Therefore, the different texture given to the viewer can be further reduced.

  According to the third invention, when a pseudo joint is formed between the ridges, the height of the ridge adjacent to the pseudo joint changes along the pseudo joint. Changes occur in the shadows that are applied. Therefore, it is possible to give the viewer an impression that the width of the pseudo joint changes unevenly. As a result, when the pseudo joint is shifted between the building boards, the shift is less noticeable. can do.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the parallel convex portion includes a plurality of types of convex portions having different surface heights.

  According to the fourth invention, since there are a plurality of types of parallel protrusions having different surface heights, the surface heights of the protrusions on both sides of the ceiling are more difficult to be aligned, and the inclination of the sealing surface is likely to occur.

  According to a fifth invention, in any one of the first to fourth inventions, the plurality of protrusions include protrusions having a width in the predetermined direction of 5 mm or more and 15 mm or less.

  According to the fifth aspect of the invention, the width of the ceiling is usually around 10 mm, and the convex portion having a width equivalent to the ceiling width is present on the surface of the building board, so that the ceiling can be made less noticeable.

  A sixth invention is directed to a construction structure of a building board in which a plurality of the building boards in any one of the first to fifth inventions are arranged side by side through sealing in a predetermined direction, and the following solution is taken. It was.

  That is, 6th invention is constructed so that the surface height of the same position in the said orthogonal direction of the said ceiling side edge part of the said building board constructed on both sides of the said ceiling may differ.

  According to the sixth invention, as in the first invention, it becomes difficult to distinguish between the surface of the ceiling and the surface of the building board, and the sealing can be made inconspicuous. As a result, it becomes difficult to give the viewer a different texture.

  According to the present invention, a part of the surface of the ceiling is inclined in the same manner as the surface of the inclined convex portion of the ridge, and the sealing surface is not continuously formed with the same inclination, and the inclination angle changes. It becomes difficult to distinguish between the surface and the surface of the building board, making it difficult to give the viewer a different texture, and making it difficult to give a cheap and easy impression to the exterior of the building.

It is a front view which shows an example of the construction state of the outer wall material which concerns on embodiment of this invention. 2A is a partially sectional enlarged perspective view schematically showing the vicinity of the ceiling in FIG. 1, and FIG. 2B is an end view of a portion A in FIG. 2A. It is a perspective view which shows typically the adjacent protrusion. It is a front view which shows a part of protrusion. 5A and 5B are diagrams schematically showing a longitudinal section of an example of the upper and lower connecting portions in a state where the outer wall materials according to the embodiment of the present invention are arranged one above the other.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, the following description of preferable embodiment is only an illustration essentially, and is not intending restrict | limiting this invention, its application thing, or its use. In addition, this embodiment demonstrates the example which applied the building board which concerns on this invention to the outer wall material.

  FIG. 1 is a front view showing a state in which a plurality of outer wall materials 1 according to the present embodiment are horizontally stretched on a wall base 3 (see FIG. 2B). Hereinafter, the horizontal direction and the vertical direction in FIG. 1 are referred to as a “horizontal direction” and a “vertical direction”, respectively. Furthermore, the back side and the near side in FIG. 1 are referred to as “indoor side” and “outdoor side”, respectively, and the “height position” in the outer wall material 1 refers to a position in the indoor / outdoor direction, and is higher on the outdoor side. To do. FIG. 1 shows a state in which sunlight is applied from the upper right.

  The outer wall material 1 is made of, for example, a ceramic siding material and a metal siding material, and has a rectangular plate shape that is long in the left-right direction. The outer wall material 1 is affixed to the wall base 3 side by side, for example, with metal fittings or nails. The outer wall materials 1 arranged in the vertical direction are connected to each other by a splice bonding described later. On the other hand, the outer wall materials 1 arranged in the left-right direction are attached with a gap 5 therebetween. The gap 5 is formed in a straight line in the vertical direction and is subjected to a sealing process. The sealing process is a process in which the sealing material filled in the gap 5 is cured to form the sealing 7. The sealing 7 prevents water from entering from the gap 5 to the back side of the outer wall material 1.

  A plurality of strip-shaped protrusions 9 extending in the left-right direction are formed on the surface 1a of the outer wall material 1 so as to be arranged in the vertical direction. A horizontal joint 11 extending continuously in the direction is formed. It is preferable that four to thirty protrusions 9 are formed in the vertical direction. Each said horizontal joint 11 is comprised by the box joint which consists of a pair of inclined surface and flat bottom which face an up-down direction. The inclined surface and bottom surface of the box joint may be angularly intersecting, or the connecting portion between the inclined surface and the bottom surface may be curved, and further, between the inclined surface and the bottom surface. A gentle gradient inclined surface (inclination angle of less than 30 °, for example) that is inclined more gently than the inclined surface may be formed. Thus, the position of the horizontal joint 11 can be made ambiguous by reducing the edge feeling without making the connecting portion between the inclined surface and the bottom surface sharp. In addition, the plurality of horizontal joints 11 are preferably formed non-uniformly and not uniformly in the vertical width.

  Each said protrusion 9 is continuously formed from the left-right direction one end of the said outer wall material 1 to the other end. Each protrusion 9 is composed of a plurality of strip-shaped convex portions 13 arranged in the left-right direction. Each of the protrusions 9 is preferably composed of 30 to 100 convex portions 13.

  2A is a partially sectional enlarged perspective view schematically showing the vicinity of the ceiling 7 in FIG. 1, and FIG. 2B is an end view of a portion A in FIG. 2A. Each of the convex portions 13 has a substantially quadrangular surface 13a, is formed with fine irregularities such as a stone surface, and both left and right sides extend in the vertical direction. The left and right widths of the convex portions 13 are not uniform and have various left and right widths. Among them, the plurality of convex portions 13 having a lateral width of 5 mm or more and 15 mm or less are randomly arranged in the lateral direction. It is preferable that the left and right convex portions 13 are formed about 10% of all the convex portions 13 formed on the surface of the outer wall material 1. Further, as shown in FIG. 2A, the convex portion 13 includes a parallel convex portion 15 having a parallel surface 15a whose surface is parallel to the vertical direction and the horizontal direction, and an inclined surface 17a whose surface is inclined to the horizontal direction. There are roughly two types of protrusions 17.

  The parallel protrusions 15 have a plurality of types of protrusions 15 having different surface heights, not all having the same surface height. On the other hand, the inclined convex portion 17 includes a right downward inclined convex portion 171 having an inclined surface 171a inclined so that the surface is lowered toward the right side, and an inclined surface 173a inclined so that the surface is raised toward the right side. There is an upper right inclined convex portion 173 (the inclined surface 171a and the inclined surface 173a are collectively referred to as “inclined surface 17a”). The parallel protrusions 15, the right downward inclined protrusions 171, and the upper right inclined protrusions 173 are irregularly arranged on a straight line to form the protrusion 9. It is preferable that the inclined surface 17a of the inclined convex portion 17 is inclined by 15 ° to 85 ° with respect to the parallel surface 15a.

  FIG. 3 is a perspective view schematically showing a part of the protrusion 9 adjacent vertically. In these protrusions 9, the sides aligned in the left-right direction of the substantially rectangular surface of the convex portion 13, that is, the sides extending in the vertical direction, are the left and right sides of the surface of the convex portion 13 adjacent to the vertical direction when viewed from the vertical direction. It is formed so as to deviate from the sides aligned in the direction.

  In addition, between the convex part 13 which comprises each said protrusion 9, the V joint (pseudo joint consisting of a pair of inclined surface which opposes the left-right direction) and box joint (a pair of inclination which opposes the left-right direction) extended in an up-down direction. A pseudo joint consisting of a surface and a flat bottom surface) is randomly provided.

  FIG. 4 is a front view showing a part of one protrusion 9. Further, as shown in FIG. 4, the upper and lower end portions of the convex portion 13 constituting each of the protrusions 9 are inclined so as to be positioned on the center side in the width direction of the convex portion 13 as it goes to the outdoor side. Tapered. In the taper portion 91, since the surface of the convex portion 13 is constituted by the parallel surface 15a and the inclined surface 17a, the vertical width of the taper portion 91 is not uniform. As a result, the width of the horizontal joint 11 appears to change unevenly in the length direction.

  Moreover, the said outer wall material 1 is connected to the up-down direction by piling. FIG. 5 is a vertical cross-sectional view schematically showing the connection locations of the outer wall materials 1 adjacent in the vertical direction. On the upper end surface of each outer wall member 1, a counterboring receiving portion 19 that protrudes upward from its indoor half is formed over the entire left and right direction. The surface 19a on the outdoor side of the joint receiving portion 19 is at a position higher than the bottom surface of the horizontal joint 11 formed on the upper end portion and the lower end portion of the outer wall material 1, in other words, the outdoor side surface 19a. The surface 19 a is formed shallower than the bottom surface of the horizontal joint 11. For example, when the depth of the horizontal joint 11 is 5.0 mm to 5.8 mm, the surface 19 a on the outdoor side of the joint receiving portion 19 has a depth of about 2.5 mm from the longest portion of the protrusion 9. Is set. Furthermore, the connection part between the surface 19a on the outdoor side of the joint receiving portion 19 and the protrusion 9 adjacent thereto is curved so as to protrude indoors. On the other hand, on the lower end surface of the outer wall material 1, an overhanging pressing portion 21 protruding downward from the outdoor half is formed over the entire left and right direction. The surface 21a is at the same height as the average height of the ridges 9, and the indoor-side surface 21a is more than the bottom surface of the horizontal joint 11 formed at the upper and lower ends of the outer wall material 1. High position.

  Then, both the outer wall materials 1 are connected in the vertical direction in a state in which the overhanging holding portion 21 of the upper outer wall material 1 is positioned on the outdoor side of the upper wall receiving portion 19 of the lower outer wall material 1. The In this state, the surface 19a on the outdoor side of the counterbore receiving portion 19 is formed shallower than the bottom surface of the horizontal joint 11 as described above, so that the shadow formed on the surface 19a on the outdoor side is It becomes thinner than the shadow formed on the horizontal joint 11. Therefore, the upper and lower connecting portions of the outer wall material 1 adjacent to each other in the vertical direction are less noticeable.

  A plurality of the outer wall materials 1 having the above-described configuration are attached to the wall base 3 vertically and horizontally. Specifically, as described above, a plurality of outer wall materials 1 connected in the up-down direction by phase splicing, and a plurality of outer wall materials 1 connected in the left-right direction and connected in the up-down direction, As shown in FIG. 2B, a sealing process is performed on the gap 5 between the two, in a state where a sealing backup material 23 such as a hat-type joiner is fixed to the wall base 3 in advance. In this state, the left and right sides of the gap 5 are formed with projections and depressions 9 in the vertical direction by the projections 9 and the horizontal joints 11, while in the left and right direction, the projections 9 are formed so as to swell in the horizontal direction. The height position is not so well aligned. Then, the sealing material is filled from the outdoor side of the backup material 23, and the surface of the sealing material is leveled up and down with a spatula or the like before the sealing material is cured. Then, a part of the surface 7 a of the ceiling 7 is inclined in the width direction from the surface of one protrusion 9 to the surface of the other protrusion 9. As a result, a part of the surface 7 a of the ceiling 7 is inclined in the same manner as the surface 17 a of the inclined convex portion 17 of the protrusion 9. Furthermore, since the plurality of protrusions 9 are provided on the surface 1a of the outer wall material 1 in the vertical direction in which the ceiling 7 extends, the surface 7a of the ceiling 7 is not continuously formed with the same inclination, and the surface 7a The inclination angle changes in the direction in which the ceiling 7 extends. Therefore, it becomes difficult to distinguish the surface 7a of the ceiling 7 from the surface 1a of the outer wall material 1, and the sealing 7 can be made inconspicuous. As a result, it is difficult to give the viewer a different texture.

-Effects of the embodiment of the invention-
According to the present embodiment, as described above, the unevenness of the outer wall material 1 and the inclination of the ceiling 7 are substantially the same, and it is difficult to give a different texture to the viewer.

  Moreover, according to this embodiment, since the convex part 13 is hard to align in the direction where the ceiling 7 extends, the inclination of the surface 7a of the ceiling 7 is likely to change depending on the extending direction. As a result, it is difficult to give the viewer a different texture, and the appearance of the building is not given an inexpensive and easy impression.

  In addition, according to the present embodiment, since there are a plurality of types of inclination of the surface 13 a of the inclined convex portion 13, the surface heights of the protrusions 9 on both sides of the ceiling 7 are more difficult to align. Therefore, the different texture given to the viewer can be further reduced. Further, even if the outer wall material 1 is cut in the vertical direction, the convex portions 13 are not easily aligned in this direction, so that the conspicuousness of the ceiling 7 can be reduced even if a cut product is applied.

  Moreover, according to this embodiment, since the height of the protrusion 9 adjacent to the horizontal joint 11 changes along the horizontal joint 11, the shadow formed on the horizontal joint 11 changes. Therefore, it is possible to give the viewer an impression that the width of the horizontal joint 11 changes unevenly. As a result, when the horizontal joint 11 is shifted between the outer wall materials 1, the shift Can be made inconspicuous. Further, since the upper and lower end portions of the convex portion 13 are tapered and the vertical width of the tapered portion 91 changes along the horizontal joint 11, the shift of the horizontal joint 11 can be made more inconspicuous.

  Furthermore, according to the present embodiment, since there are a plurality of types of parallel protrusions 15 having different surface heights, the surface heights of the protrusions 9 on both sides of the ceiling 7 are more difficult to align, Inclination tends to occur.

  Furthermore, according to this embodiment, the width of the sealing is normally around 10 mm, and the convex portion 13 having a width equivalent to the width of the sealing 7 is present on the surface 1a of the outer wall material 1, so that the sealing 7 is It can be less noticeable. Moreover, since the convex part 13 of the left-right width | variety is formed about 10% with respect to the whole area of the surface 1a of the outer wall material 1, the same texture as the sealing 7 is given and this sealing 7 becomes much less conspicuous.

(Modification of Embodiment of Invention)
In the above embodiment, the outer wall material has been described as an example of the building board. However, the invention is not limited thereto, and any building board may be used as long as it is constructed using a ceiling.

  Moreover, in the said embodiment, although the example in which the outer wall material 1 was horizontally stretched was demonstrated, it is not limited to this, For example, it may be vertically stretched. In the case of vertical construction, the ceiling 7 is constructed in a horizontally extending gap between the outer wall materials 1 adjacent to each other in the vertical direction, and the surface of the ceiling 7 is inclined in the vertical direction so as to be along the edge of the outer wall material 1 on both the upper and lower sides. To be provided.

  Moreover, in the said embodiment, although the connection part of the surface 19a of the outdoor side of the joint receiving part 19 and the protrusion 9 adjacent to it is curved, it is not limited to this, For example, the inclined surface from which an inclination angle differs May be formed in multiple stages. Further, as shown in FIG. 5B, the surface 19 a on the outdoor side of the contact receiving portion 19 and the upper end surface of the outer wall material 1 may be orthogonal to each other.

  In addition, in the above-described embodiment, the inclined surface 17a of the inclined convex portion 17 includes the inclined surface 171a and the inclined surface 173a on the upper right side, which are combined into the inclined surface 17a. Also good.

  The present invention is useful as a building board used for outer wall materials and the like.
