Description of the Related Art At present, ceramic exterior materials account for almost 70% of architectural exterior materials, and their designs are becoming more sophisticated and complicated. However, no matter how sophisticated a design pattern is designed on a board basis, if the continuity of the design is lost at the joint between the boards, sufficient appearance design cannot be obtained. Since ceramic building boards are manufactured as long boards, it is inevitable that a linear gap will be formed at the joint between the boards in the normal form, and It is not easy to have continuity. This problem is the same not only in the case of butting work but also in the case of joint joining.

の手法を採用することは困難である。One pattern is divided into two plates and held, and when joined, one pattern is formed so that the continuity of the pattern is provided. In this way, it is easy to form the entire board, including the forming process near the side edge that is to be the seam, but it is necessary to avoid the appearance of linear joining lines (seam lines) on the surface of the pattern part. No, it is not fully satisfactory from the viewpoint of continuity of the entire design. One in which the entire pattern is formed on one of the adjacent building boards, and when the two building boards are joined, a part of the pattern is projected on the side edge portion of the other building board, The integrity of the pattern is ensured, and the joining line is cut off by the crossing of the pattern, so that the joining line becomes inconspicuous, and a quite satisfactory wall surface appearance is obtained, but the seam side It is difficult to employ this method in the case where forming near the edge is not easy and a large number of building boards are continuously formed.

In the building board formed so as to face each other, the part where the upper solid part is formed is the end side of the convex pattern part, and the lower solid part is the convex pattern part formed on the other side edge. It has at least an area corresponding to the area of the solid part, and has a straight joining end face formed on the back surface side, and further, a part or all of the solid part has a depth opening the side edge side. The upper part formed on the other side edge opposite to the lower part forming the deep part has another part corresponding to the deep part. It is characterized by being thicker than the solid part. Preferably, the convex pattern is an island-shaped pattern portion, and when joining two building boards, a solid portion and a lower portion are provided on the side edge so that a linear joint is not formed on the surface side. The real part is arranged.

ものに違和感を与えない。[0007] In the above-mentioned building board, two adjacent building boards are joined to each other by a so-called abutting, in which linear joining end faces formed on the back side abut each other preferably with a caulking material or the like interposed therebetween. This is performed by both joining and so-called joint joining, in which the lower solid portion of one building board overlaps the lower solid portion of the other building board. And
Since the butt joint is covered from the front side by the mating joint, the gap formed in the butt joint is almost invisible. Even when it is visible, the gap is discontinuous, so that the viewer does not feel strange.

なる。Further, the convex pattern is formed without being divided at the side edge of the building board, and is formed at the end of the convex pattern at a solid portion, so that the pattern pattern is integrated and continuous. And both can be satisfied at the same time. In the case where the convex pattern is an island pattern, it is also easy to form a zigzag concave groove pattern at a joint portion between two building boards.

The solid portion formed on the other side edge facing the opposite side is thicker than the other solid portion by an amount corresponding to the deep portion, so that two adjacent left and right building boards are provided. When joining together, both building boards can be positioned in the left-right direction at a position where the tip end surface of the thickened solid part abuts the inner end face of the deep part.

ちにくくなる。[0010] Therefore, by forming the deep portion of the solid portion at a predetermined position by embossing or the like, the width of the concave groove in the concavo-convex pattern at the joint portion of the two adjacent left and right building boards is determined. It becomes easy to unify the width, and the zigzag groove pattern at the joint portion can be surely matched with the zigzag groove pattern on the building board surface. Thereby, the continuity of the entire design pattern in the wall surface appearance is more reliably ensured. Also, it is constructed so that the upper part fits into the deep part of the lower part,
Even if there is a slight construction defect, the lifting of the building board becomes less noticeable.

It is easy to perform, and a caulking material can be cast in the gap between the linear joining end surfaces to ensure the waterproof function.

Since the flow of rainwater that enters from the zigzag concave groove pattern portion at the joint portion due to the step is blocked and flows out to the surface side,
It is possible to prevent rainwater from leaking to the back surface through the abutting portion between the linear joining end surfaces formed on the back surface side.

築板の製造方法である。Although the building board according to the present invention can be manufactured by any method, high manufacturing efficiency can be increased by manufacturing by the following method. In other words, at least a region which is a solid portion on one side edge of the building board is formed in advance by embossing a region having a reduced thickness including the portion where the depth is increased, and the other side edge is formed. At least, a region corresponding to the lower solid portion is a region having a depth corresponding to the depth of the deepened portion on the distal end side and a region corresponding to the depth of the subsequent thinned portion. A region having a reduced thickness is formed in advance by embossing, and then, from both side edges toward the inside, a thickness corresponding to the thickness of the reduced thickness portion for the one side edge Material is removed over the entire length of the side edge, and for the other side edge, the material remaining on the distal end side in the region serving as the lower solid portion is removed over the entire length of the side edge, whereby the thickness is reduced. Not thinned Forming a two on the real part having different thicknesses in a portion, at the same time, a method for producing a building board to form a linear joint end face on the back side.

ても何の不都合も生じない。In the above-described manufacturing method, the step of embossing a region having a different thickness in a region which is a lower solid portion on both left and right side edges by embossing comprises forming a pattern on a conventional embossed surface. Embossing may be performed in the same manner, and the operation is extremely easy. The embossing may be performed on the area to be the lower solid part at the same time as the pattern is processed on the embossed surface, and in that case, the working process is further simplified. Subsequent work of removing a predetermined material over the entire length of both side edges can be performed in the same manner as when cutting a top or bottom in a conventional building board manufacturing process, and the work is extremely easy. . In addition, since a straight joining end face is formed on the back side together with the removal operation, the number of molding steps of the entire building board is the same as the conventional number of molding steps, and a large number of building boards of the same standard are continuously produced. In this case, no inconvenience occurs even if the above-mentioned manufacturing method is applied.

にくくなる利点もある。In particular, when two adjacent left and right building boards are joined together, the inner end face of the deep part formed in the lower solid part is contacted with the tip end face of the thick solid part. Since the two building boards can be positioned in the left-right direction by being in contact with each other, it becomes easy to unify the groove width in the concavo-convex pattern at the joint portion between the two adjacent left and right building boards to a predetermined width. In addition, the zigzag groove pattern at the joint portion can be reliably matched with the zigzag groove pattern on the building board surface. Further, since the construction is performed so that the upper part fits into the deep part of the lower part, there is an advantage that even if there is a slight construction defect, the floating of the building board is less noticeable.
