  In the outer wall plate described in Patent Document 1, since the uneven pattern of the joint joint of the horizontal joint is formed higher than the uneven pattern of the joint joint of the vertical joint, the joint structure between the outer wall plates and the joint material can be easily and easily felt. Can be formed.

  However, in the outer wall plate described in Patent Document 1, if the position of the vertical joint, which is a through joint, is shifted to the left and right, this positional shift becomes conspicuous.

  Moreover, in the exterior plate described in Patent Document 2, the height of the uppermost protrusion formed on the uppermost portion of the exterior plate body is set higher than the height of the lowermost protrusion formed on the lowermost portion of the exterior plate body. ing. Therefore, when the exterior plate stretched on the surface of the building is viewed from the outside, the lowermost protrusion is less noticeable, and even if there is some variation in the dimensions of the connection part, the pattern of the protrusion on the surface of the exterior plate body It is difficult to feel discomfort in continuity.

  However, in the exterior plate described in Patent Document 2, a recess is formed as a joint between the protrusion and the protrusion. However, when the position of the recess is shifted up and down, the position shift becomes conspicuous. .

  The present invention has been made in view of the above points, and when a plurality of outer wall materials are installed adjacent to each other in one direction, even if the position of the through joint at the joint portion of the adjacent outer wall materials is slightly deviated, this misalignment is caused. It is an object of the present invention to provide an outer wall material that can make it less noticeable.

  The outer wall material according to the present invention is formed by providing a through joint on one surface of the base material from one end to the other end on the surface of the base material, and the joint width of the one end of the through joint and the through joint The joint width of the other end is different.

  In the outer wall material, it is preferable that the base material is rectangular and a plurality of through joints are provided so as to be parallel to the short side of the base material.

  In the outer wall material, it is preferable that an orthogonal through joint perpendicular to the through joint is provided from one end portion to the other end portion in a direction orthogonal to the one direction of the base material.

  In the outer wall material, the joint width of the one end portion of the through joint is the narrowest minimum width, the joint width of the other end portion of the through joint is the widest maximum width, and the one end portion of the through joint It is preferable that the joint width between the other end portion is changed between the minimum width and the maximum width.

  According to the present invention, when a plurality of outer wall materials are installed adjacent to each other in one direction, the joint joint width at the joint portion of one adjacent outer wall member and the joint joint at the joint portion of the other adjacent outer wall member. Since the joint width is originally different, the positional shift can be made inconspicuous even if the position of the through joint between the two is slightly shifted.

  Embodiments of the present invention will be described below.

  The outer wall material according to the present invention can be manufactured using, for example, a ceramic board such as a cement board as the base material 1. The substrate 1 is usually a rectangle having one side as a short side and a direction perpendicular to the one direction as a long side, but may be a square. The magnitude | size of the base material 1 is 300-1000 mm x 600-3636 mm, for example.

  FIG. 1 shows an example of an outer wall material according to the present invention. The outer wall material is formed by providing joints 2 on the surface of the base material 1 from one end to the other end in one direction of the base material 1. That is, in FIG. 1, vertical joints are provided as through joints 2 on the surface of the base material 1 from one end portion to the other end portion of the base material 1 in the vertical direction (vertical direction, double-headed arrow Y). The number of through joints 2 is not particularly limited, but it is preferable to provide a plurality of through joints 2 at substantially equal intervals so as to be parallel to the short side of the substrate 1 as shown in FIG. Although not shown, at least one end of the base material 1 is subjected to a knitting process.

In addition, although only the through joint 2 may be provided on the surface of the base material 1, an orthogonal through joint 3 that is orthogonal to the through joint 2 extends from one end portion to the other end portion in a direction orthogonal to one direction of the base material 1. It is preferable to provide it. That is, in FIG. 1, a horizontal joint is provided as an orthogonal through joint 3 from one end to the other end of the base material 1 in the left-right direction (lateral direction, double-headed arrow X). The orthogonal through joint 3 may not be provided. Although the number of orthogonal through joints 3 is not particularly limited, in FIG. 1, a plurality of orthogonal through joints 3 are provided at substantially equal intervals so as to be parallel to the long side of the substrate 1. In this way, a plurality of through joints 2 and a plurality of orthogonal through joints 3 intersect in a lattice pattern and a plurality of rectangular portions 4 are formed on the surface of the base material 1, thereby providing a tile-like or brick-like pattern. Can be obtained. Thereby, the designability of an outer wall material can be improved.
A pattern can be formed in the rectangular portion 4, and this pattern is not particularly limited, but it is preferable to form a thin line pattern substantially parallel to the through joint 2. The size of the rectangular portion 4 is, for example, 35 to 220 mm × 35 to 220 mm.

  Below, for convenience of explanation, one direction is the vertical direction (vertical direction, double-headed arrow Y), the direction orthogonal to one direction is the left-right direction (horizontal direction, double-headed arrow X), and the through joint 2 is the vertical joint, Although the orthogonal through joint 3 is a horizontal joint, the present invention is not limited to this, and the vertical and horizontal (vertical and horizontal) may be reversed.

In the present invention, as shown in FIG. 2, the joint width W ₁ at one end of the through joint 2 is different from the joint width W _{n at} the other end of the through joint 2. In Figure 2, narrowing the joint width W ₁ of the upper end portion of the through joints 2, widely the joint width W _n of the lower end. While the following describes this case, the joint width W ₁ of the upper end portion of the through joints 2 wide, may be narrow joint width W _n of the lower end.

Further, the left side surface L ₁ of the through joint 2 at one end portion having the narrow joint width W ₁ coincides with the left side surface L _n of the through joint portion 2 at the other end portion having the wide joint width W _n or the right side thereof. The right side surface R ₁ of the through joint 2 at one end having a narrow joint width W ₁ is equal to or more than the right side surface R _n of the through joint 2 at the other end having a wide joint width W _n. Is also on the left. Specifically, in FIG. 2A, the left side surface L ₁ of the upper joint portion 2 having a narrow joint width W ₁ is the left side surface L _n of the lower joint portion 2 having a wide joint width W _n. consistent with a right side R ₁ of the through joints 2 of the upper end portion having a narrow joint width W ₁ is located on the left side than the right side R _n of through joints 2 of the lower end portion having a wider joint width W _n . Also in FIG. 2 (b), the left side L ₁ of the through joints 2 of the upper end portion having a narrow joint width W ₁ is the right side of the left side L _n of through joints 2 of the lower end portion having a wider joint width W _n position, and the right side R ₁ of the through joints 2 of the upper end portion having a narrow joint width W ₁ is located on the left side than the right side R _n of through joints 2 of the lower end portion having a wider joint width W _n. Also in FIG. 2 (c), the left side L ₁ of the through joints 2 of the upper end portion having a narrow joint width W ₁ is the right side of the left side L _n of through joints 2 of the lower end portion having a wider joint width W _n position, and the right side R ₁ of the through joints 2 of the upper end portion having a narrow joint width W ₁ is coincident with the right side R _n of through joints 2 of the lower end portion having a wider joint width W _n. Note that the left side surface L and the right side surface R of the through joint 2 mean boundary surfaces between the through joint 2 and the rectangular portion 4.

Further, the joint width W _k of the through joint 2 of the part other than the one end part and the other end part (midway part) is not particularly limited, for example, periodically, intermittently from one end part to the other end part, The width can be changed continuously, discontinuously, regularly or irregularly. However, when the through joint 2 having the wide joint width W _k and the through joint 2 having the narrow joint width W _{k + 1} are adjacent to each other through the orthogonal through joint 3 as shown in FIG. 3, the narrow joint width W _{k + 1.} The left side surface L _{k + 1} of the through joint 2 having the same width as the left side surface L _k of the through joint 2 having the wide joint width W _k is located on the right side of the through joint 2 and has the narrow joint width W _{k + 1.} Right side surface R _{k + 1} coincides with or is located on the left side of right side surface R _k of through joint 2 having a wide joint width W _k . Specifically, in FIG. 3 (a), the left side L _{k + 1} of the lower through joint 2 having a narrow joint width W _{k + 1} is a left side L _k of the upper through joint 2 having a wider joint width W _k The right side surface R _{k + 1} of the lower through joint 2 that coincides and has the narrow joint width W _{k + 1} is located on the left side of the right side surface R _k of the upper through joint 2 that has the wide joint width W _k . 3B, the left side surface L _{k + 1} of the lower through joint 2 having the narrow joint width W _{k + 1} is positioned on the right side of the left side surface L _k of the upper through joint 2 having the wide joint width W _k. The right side surface R _{k + 1} of the lower through joint 2 having the narrow joint width W _{k + 1} is located on the left side of the right side surface R _k of the upper through joint 2 having the wide joint width W _k . In FIG. 3C, the left side surface L _{k + 1} of the lower through joint 2 having the narrow joint width W _{k + 1} is positioned on the right side of the left side surface L _k of the upper through joint 2 having the wide joint width W _k. The right side surface R _{k + 1} of the lower through joint 2 having the narrow joint width W _{k + 1} coincides with the right side surface R _k of the upper through joint 2 having the wide joint width W _k .

In particular, it is preferable that the joint width W ₁ at one end of the through joint 2 is the smallest minimum width, and the joint width W _{n at} the other end of the through joint 2 is the widest maximum width. At this time, the difference between the maximum width and the minimum width is, for example, 0.5 to 3 mm. That is, the joint width W _{1 at} the upper end of the through joint 2 is the minimum width, the joint width W _{n at the} lower end is the maximum width, or the joint width W _{n at the} lower end is the minimum width, and the joint width W _{1 at the} upper end is the maximum width. It is preferable that In this case, the joint width W _k (one-way joint width W _k ) between one end and the other end of the through joint 2 changes between the minimum width and the maximum width. Specifically, in FIG. 1, the joint width W _{1 at} the upper end of the through joint 2 is the minimum width (6.0 mm), the joint width W _{n at the} lower end is the maximum width (7.0 mm), joint width _{W k} is 6.5mm, 7.0mm, 6.0mm, and varies between a minimum and maximum width and so 6.5 mm. Further, the joint width W _k (k = 1 to n) of the through joint 2 is 6.0 mm, 6.5 mm, 7.0 mm, 6.0 mm, 6.5 mm, 7.0 mm from the upper end to the lower end. It changes periodically or regularly.

Further, when a plurality of through joints 2 are provided as shown in FIG. 1, the joint width W ₁ at one end and the joint width W _{n at the} other end may not be different for all the through joints 2. That may be the same as the joint width W _n of joint width W ₁ and the other end portion of the one end portion for some through joint 2. In this case, the ratio of the number of through joints 2 in which the joint width W ₁ at one end and the joint width W _{n at the} other end are different is preferably 50 to 100% with respect to the number of all through joints 2. .

  Next, the installation structure of the outer wall material formed by installing the outer wall material according to the present invention will be described. FIG. 4 shows an example of the installation structure of the outer wall material. This outer wall material installation structure is formed by installing a plurality of outer wall materials adjacent to each other in the vertical direction and the horizontal direction.

  In particular, when the plurality of outer wall materials are installed adjacent to each other in the vertical direction, the position of the through joint 2 at the joint location of the adjacent outer wall materials when using the conventional outer wall material and when using the outer wall material according to the present invention. Easiness of deviation is different.

In the conventional outer wall material, the joint width W of the through joint 2 provided in the base material 1 is the same in any part. Therefore, when such an outer wall material is installed adjacent in the vertical direction, as shown in FIG. 6B, the left side surface L _n , L ₁ and the right side surface R _n , R ₁ of the upper and lower through joints 2 are respectively set. Must match exactly. However, it is difficult to actually do this, and it is usually as shown in FIGS. 6 (a) and 6 (c). That is, in FIG. 6 (a), located on the right side than the left side L ₁ of the lower through joint 2 left side L _n of the upper through joint 2 is a right side R _n of the upper through joint 2 is under It is located on the right side of the right side surface R ₁ of the side through joint 2. Therefore, it gives to the person who sees the impression that the joint location is greatly displaced in the upper right and lower left direction. Also in FIG. 6 (c), the located on the left side of the left side L ₁ of the lower through joint 2 left side L _n of the upper through joint 2, the lower right side R _n of the upper through joint 2 side Is located on the left side of the right side surface R ₁ of the through joint 2. Therefore, it gives to the person who sees the impression that the joint location is greatly displaced in the upper left and lower right direction. In addition, in the conventional outer wall material shown in FIG. 6, the orthogonal through joint 3 and the rectangular part 4 are illustrated for convenience of explanation in comparison with the outer wall material according to the present invention.

On the other hand, in the outer wall material according to the present invention, joint widths W ₁ and W _n at both ends of the through joint 2 provided on the base material 1 are originally different. Therefore, when such an outer wall material is installed adjacent in the vertical direction, the left side surface L _n , L ₁ and the right side surface R _n , R ₁ of the upper and lower through joints 2 cannot be made to coincide with each other, Either the left side surface L _n , L ₁ or the right side surface R _n , R ₁ is matched, or both side surfaces L ₁ , R _{1 of the} through joint 2 having a narrow joint width W ₁ have a wide joint width W _n . both sides L _n of through joint 2 having _may be so as to be positioned between the R _n. That is, in FIG. 5 (a), the left side L _n of the upper through joint 2 coincides with the left side L ₁ of the through joints 2 of the lower, through the right side R _n of the upper through joint 2 is lower It is located on the right side of the right side surface R ₁ of the joint 2. As described above, the right side surfaces R _n and R ₁ are displaced in position, but the left side surfaces L _n and L ₁ are coincident with each other. Therefore, compared with the conventional one shown in FIG. It is hard to give to the person who sees the impression that the location is displaced in the upper right and lower left direction. In FIG. 5B, the left side surface L _n , L ₁ and the right side surface R _n , R ₁ of the upper and lower through joints 2 do not match, but the left side surface L _n of the upper through joint 2 is lower side. located from the left side L ₁ of the through joints 2 on the left, right side R _n of the upper through joint 2 is positioned on the right side of the right side R ₁ of the through joints 2 on the lower side. That is, since both side faces L ₁ and R _{1 of the} through joint 2 having the narrow joint width W ₁ are closer to the center, the continuity in the vertical direction is emphasized compared to the positional deviation in the left and right direction. Also in FIG. 5 (c), the right side R _n of the upper through joint 2 coincides with the right side R ₁ of the through joints 2 of the lower, through the left side L _n of the upper through joint 2 is lower joint It is located on the left side of the second left side L _1. As described above, the positions of the left side surfaces L _n and L ₁ are shifted, but the right side surfaces R _n and R ₁ coincide with each other, and therefore, compared with the conventional one shown in FIG. It is hard to give to the person who sees the impression that the location is displaced in the upper left and lower right direction.

As described above, when a plurality of outer wall materials according to the present invention are installed adjacent to each other in one direction, the joint width W1 of the through joint 2 at the joint portion of _one adjacent outer wall material and the other outer wall material adjacent to each other. It is different and joint width W _n of through joints 2 in the joint. This is because the joint widths W ₁ and W _n at both ends of the through joint 2 of the outer wall material according to the present invention are originally different. Even if there is a slight deviation, this positional deviation can be made inconspicuous.

Further, in the outer wall material shown in FIGS. 1 and 4, since a plurality of through joints 2 are provided, only a specific joint portion is not noticed, and the position shift of the through joint 2 at the joint portion is further less noticeable. It is something that can be done. Further, the joint width W ₁ at one end of the through joint 2 is the minimum width, the joint width W _{n at} the other end is the maximum width, and the joint width W _{k at the} midway portion is changed between the minimum width and the maximum width. Therefore, the positional deviation itself of the through joint 2 at the joint portion can be seen as a kind of pattern and can be made less noticeable.

  In addition, when installing a plurality of outer wall materials adjacent to each other in the left-right direction as shown in FIG. 4, the sealing material 5 is used at a joint portion between adjacent outer wall materials, and the vertical sealing material 5 itself is relatively conspicuous. Therefore, the positional deviation of the right and left orthogonal joints 3 at the joints is not noticeable.
