[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural wall plate, and more particularly, to a wall plate having a shape in which various kinds of rectangular stones or the like are irregularly stacked on the surface.

[0002]

2. Description of the Related Art Heretofore, as a kind of wall plate for finishing an exterior of a building, a type imitating a masonry pattern in which rectangular stones of various sizes are irregularly stacked is known. For example, as shown in FIG.
Surface grooves 2 and 3 extending in the vertical and horizontal directions and intersecting with each other are formed on the surface by appropriate molding means, and various kinds of rectangular portions 4 irregularly arranged by the grooves 2 and 3 are formed.
4,... Are defined, and each rectangular portion 4 is defined as a “stone” to indicate a random stacking pattern. Then, the above-mentioned surface groove 2
As shown in FIG. 6, (and 3) has a substantially U-shaped cross section in which the width of the opening is larger than that of the bottom.

[0003] Further, since the wall plate B 'is vertically stacked and attached to a building, one of a male part or a female part is provided on the upper end face of the substrate 1, and a male part or a female part is provided on the lower end face. The other of the real portions is formed, and the wall plates B ', B',... Are continuously joined up and down by fitting the male and female portions, and thus the wall plate B ' , B ',... Are continuously attached to the outer surface of the building up and down, thereby making it possible to form a wall with a stone-like pile.

In this case, the vertically adjacent wall plates B ', B'
, A substantially U-shaped concave groove 12 similar to the concave grooves 2 and 3 in the middle part of the wall plate B 'is formed. So that they are divided,
The rectangular portions 4, 4,...
B ′,... Are made to be irregularly continuous. For example, at one of the upper end and the lower end of the surface of the substrate 1, a notch formed by diagonally cutting a surface corner of the substrate 1 is formed, and the other is formed by diagonally cutting a surface corner of the substrate 1. A notch step comprising an inclined surface portion and a flat portion continuous with the inclined surface portion is formed, and the notch portion and the notch step portion are jointed by the fitting of the male part and the female part at the joint part. It is configured so that the groove 12 is formed.

[0005]

However, since each wall plate B 'is joined at a joint, the groove 12 of the joint continues on a straight line in the left-right direction. The joint part was conspicuous as it was out of the pattern of random accumulation, and there was a difficulty in the appearance of the appearance of the stone-like irregular wall surface becoming poor.

Therefore, a groove 1 is formed in the joint of the wall plate B '.
It is conceivable that the upper and lower end surfaces of the wall plate B 'are joined to each other by abutting up and down on a horizontal plane portion without forming the wall plate B'. There is a problem when considering the flow of rainwater.

[0007] The present invention has been made in view of the above points, and an object of the present invention is to improve the shape of the concave groove of the joint portion in the wall plate without causing a problem regarding the flow of rainwater or the like. It is an object of the present invention to improve and maintain the appearance of a wall-like appearance of a random pile of stones or the like by a wall plate by making the joint part inconspicuous.

[0008]

In order to achieve the above object, according to the present invention, the shape of the groove at the joint part is partially different from that of the other part, so that the shape of the groove is substantially U-shaped. The shape of the groove is prevented from being seen in a straight line.

Specifically, according to the present invention, recesses are formed on the surface of the substrate such that surface recessed grooves extending in the vertical and horizontal directions and having a substantially U-shaped cross-section and having a width of the opening larger than the depth of the bottom are formed. The surface concave groove defines a variety of rectangular portions arranged irregularly, and these rectangular portions form a random stacking pattern of stones and the like. While one of the real part or the female part is formed, the other of the male part or the female part is formed on the lower end surface, and the male part is continuously joined up and down by fitting to the female part. It is premised on a building wallboard configured to be operated.

Further, a first notch is formed at one of an upper end and a lower end of the substrate surface by diagonally cutting a surface corner of the substrate. On the other hand, on the other part of the upper end or the lower end of the substrate surface, a notch step portion formed by an inclined surface portion obliquely notched at the surface corner portion of the substrate and a flat surface portion continuous with the inclined surface portion is formed, and the remaining portion is formed. Forms a second notch formed by diagonally notching a surface corner of the substrate. Then, by fitting the male boss into the female boss, a joint groove having the same cross-sectional shape as the surface groove is formed by the first notch and the notch step. The second notch is configured to form a joint groove having a V-shaped cross section.

In the invention of claim 2, a part of the surface groove extending in the left-right direction is a groove having a V-shaped cross section.

[0012]

According to the above construction, according to the first aspect of the present invention, when the wall plates are vertically overlapped and joined, the male part of one wall plate is fitted to the female part of the other wall plate. Both wall boards are joined. At this time, the joint portion of the wall plate has a first cutout portion on the surface of one wall plate and a cutout step portion on the surface of the other wall plate, and a joint portion having a substantially U-shaped cross section similar to the surface groove. A concave groove is formed. Also, a joint notch having a V-shaped cross section different from the surface groove is formed by the first notch in the one wall plate and the second notch in the surface of the other wall plate. That is, since a part of the joint groove at the joint portion of both wall plates is formed as a V-shaped cross-sectional groove, the joint portion between the wall plates can be suppressed from being conspicuous, and the stone by the wall plate can be suppressed. It is possible to improve and maintain the appearance of the wall appearance in a random pattern.

Further, since the joint groove has substantially U-shaped and V-shaped cross-sections arranged in series on a straight line, the flow of rainwater or the like can be prevented even if the wall plate is attached horizontally. There is no problem such as rainwater etc. entering the back side of the wall board, and the workability and workability of the wall board are the same as those of the conventional example where the joint groove is only a U-shaped cross section. Be equivalent.

According to the invention of claim 2, since a part of the groove on the surface in the left-right direction of the wall plate is a groove having a V-shaped cross section, the concave groove having a V-shaped cross section in the joint groove is formed. By arranging the grooves also in the grooves on the wall plate surface, it is possible to make it appear that the V-shaped cross-sectional grooves are not arranged only in the joint portion, and the position of the joint portion can be made more inconspicuous.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. Since the basic configuration of this embodiment is the same as that of FIG. 5, the same parts as those of FIG.

FIG. 1 shows an embodiment of the present invention, wherein B is a wall plate, and the wall plate B is composed of a substrate 1 such as a calcium silicate plate, a calcium silicate extruded plate, or an ALC. .., 2 ′, 2 ′,... Extending in the left-right direction, and upper and lower surface recesses 3, 3,. Are irregularly arranged so as to intersect with each other, and the left and right surface concave grooves 2 and the upper and lower surface concave grooves 3 each have a substantially U-shaped cross section in which the width of the opening is larger than the depth of the inner bottom. The left and right surface concave grooves 2 'are concave grooves having a V-shaped cross section as shown in FIG. Various rectangular portions 4, 4,... Arranged irregularly by these surface concave grooves 2, 2 ', 3 are defined, and the color and texture of the surface of each rectangular portion 4 are natural. It resembles a stone, and a random stacking pattern of stones is formed by these various types of rectangular portions 4, 4,.

As shown in FIG. 2 and FIG. 3, a male part 5 is formed on the upper end surface of the substrate 1 by cutting a corner on the front side into a rectangular cross section except for the back side of the substrate 1. On the other hand, a female part 6 is formed on the lower end surface by cutting a corner on the back side of the substrate 1 into a rectangular cross section. By fitting the male part 5 of the lower side wall plate B into the female part 6 at the lower end of the plate B, the upper and lower wall plates B, B are joined in a state of being vertically overlapped. .

At the lower end of the surface of the substrate 1, there is formed a first notch 7 formed by diagonally notching a surface corner of the substrate 1 downward toward the back side of the substrate 1.

On the other hand, the most part of the upper end of the surface of the substrate 1 has an inclined surface portion 8 in which a surface corner of the substrate 1 is cut obliquely so as to incline upward toward the back side of the substrate 1. A notch step 10 composed of a flat portion 9 extending upward from the upper end and extending parallel to the back surface is formed. In the remaining portion at the upper end of the surface of the substrate 1, a second corner formed by diagonally notching the surface corner of the substrate 1 so as to incline upward toward the back side of the substrate 1.
Is formed. When the upper and lower wall plates B are joined by fitting the male part 5 to the female part 6, the first notch 7 at the lower end of the upper wall plate B as shown in FIG. The notch step 10 at the upper end of the lower side wall plate B and the joint groove 12 having substantially the same U-shaped cross section as the surface groove 2 on the surface of the wall plate B, as shown in FIG. 7
And the second notch 11 at the upper end of the lower side wall plate B, a joint groove 13 having a V-shaped cross section similar to the left and right surface groove 2 '.
Are formed respectively, and these joint concave grooves 12, 13 divide rectangular portions 4, 4,... Located at the upper and lower end positions of the wall plate B surface. In other words, most of the joint groove in the joint between the upper and lower wall plates B, B is a substantially U-shaped groove 12 in cross section.
A part is a concave groove 13 having a V-shaped cross section.

Therefore, in the above embodiment, when the wall plates B, B,...
By fitting the male part 5 at the upper end of the lower wall plate B into the female part 6 at the lower end, the two wall plates B, B are joined. At this time, the first cutout 7 at the lower end of the surface of the substrate 1 in the upper side wall plate B and the first notch 7 at the lower end of the surface of the substrate 1 in the lower side wall plate B are formed at the joint portion of the two wall plates B, B as shown in FIG. With the notch step 10,
A cross section substantially U similar to the surface concave grooves 2 and 3 on the surface of each wall plate B
A U-shaped joint groove 12 is formed. At the same time, the lower second side wall B has an inclined second lower surface on the substrate 1 surface.
In the portion where the notch 11 is formed, as shown in FIG. 3, the second notch 11 and the first notch 7 in the upper wall plate B form A joint groove 13 having a V-shaped cross section different from the surface grooves 2 and 3 is formed.

As described above, the concave groove at the joint between the wall plates B, B is composed of the joint concave groove 12 having a substantially U-shaped cross section and the joint concave groove 13 having a V-shaped cross section. The joint between the wall plates B, B becomes less noticeable.
In addition, since a part of the left and right surface concave grooves 2 ′ on the surface of each wall plate B is formed as a V-shaped concave groove, the V-shaped concave groove 13 in the joint portion is formed on the wall plate B surface. And it can be seen that the V-shaped groove 13 is not limited to the joints of the wall plates B and B.
It is possible to make the position of the joint less noticeable. Thus, it is possible to improve and maintain the appearance of the wall surface appearance of the stone piled by the wall plate B.

Since the joint grooves 12 and 13 have substantially U-shaped and V-shaped cross-sections arranged in series on a straight line, the wall plates B, B,. Even the flow of rainwater etc. becomes smooth. In addition, the workability and workability of the wall plate B can be kept good by making it equal to that of the conventional example in which the joint groove is only U-shaped in cross section.

In the above embodiment, the pattern on the surface of the wall plate B is a random pattern of stones. However, by changing the color, texture, etc. of the surface of the rectangular portion 4, other elements such as blocks are randomly stacked. It can also be a patterned pattern.

In the above embodiment, the first notch 7 is formed at the lower end of the surface of the wall plate B, and the notch step 10 and the second notch 11 are formed at the upper end of the surface of the wall plate B. These formation positions may be reversed.

Further, in the above-described embodiment, the wall plate B is used by being pasted horizontally, but the wall plate B can be used by vertically pasting it by changing the direction of the wall plate B by 90 °. The joints B and B can be made inconspicuous.

The above embodiment is directed to the case of the wall plate B in which the male part 5 or the female part 6 is formed on the upper and lower end surfaces of the substrate 1. However, the present invention is not limited to the upper and lower end surfaces of the substrate. The present invention can also be applied to a wall plate having a structure in which a male part or a female part is formed on the end face. In that case, by forming the same notch or notch step as in the above embodiment at both the upper and lower ends and the left and right ends of the substrate surface, each joint portion of the wall plates adjacent not only in the vertical direction but also in the horizontal direction The joint groove having a substantially U-shaped cross section and the joint groove having a V-shaped cross section may be arranged in series. This is also advantageous because it can be less noticeable. Further, at this time, both the left and right surface vertical grooves on the substrate surface may be partially V-shaped concave grooves similar to the joint V-shaped concave grooves described above.

[0027]

As described above, according to the first aspect of the present invention, various types of rectangular portions are defined on the surface of the substrate by the surface concave grooves having a substantially U-shaped cross section in the vertical and horizontal directions crossing each other. In the wallboards formed in a random pile pattern such as stones and joined vertically at the joints at the upper and lower ends of the substrate, the joints between the wallboards have substantially the same cross-section U as the surface of each wallboard. Since the joint groove having a V-shape and the joint groove having a V-shaped cross section are formed, it is difficult for the groove of the joint between the two wall plates to seem to be continued in a straight line. Can be suppressed, and the appearance of the wall appearance can be improved and maintained in the form of random stacking of stones or the like by the wall plate.

According to the second aspect of the present invention, since a part of the groove on the surface in the left-right direction of the wall plate is a groove having a V-shaped cross section, the groove having a V-shaped cross section in the joint groove is provided. The grooves can also be arranged in the groove on the wall plate surface, so that the V-shaped cross-section groove does not appear to be arranged only in the joint part,
It is possible to make the position of the joint less noticeable.
