TECHNICAL FIELD The present invention relates to a building board that constitutes a wall of a building, and a construction structure of building boards in which building boards are arranged side by side.

Ceramic siding boards, metal siding boards, and the like are used as building boards that form the outer walls of buildings. On the surface of the building board, a square uneven pattern is formed in order to create an appearance pattern of tiles, bricks, and stones. By constructing such building boards vertically and horizontally, an outer wall with a highly designed appearance is constructed, which exhibits an appearance pattern in which tiles, bricks, stones, etc. are stacked.

In the case of a building board having a rectangular concave-convex pattern, concave patterns (vertical joints, horizontal joints) are formed as horse joints in the vertical and horizontal directions between the convex patterns. In this case, convex pattern portions obtained by dividing one convex pattern are formed alternately on both ends of one building board, and vertical joints are formed through the ends. Therefore, when the building boards are joined together in the horizontal direction, the seams do not form a horse-joint pattern, and one projecting pattern appears to be divided by the vertical joints, giving a sense of incongruity.

Therefore, in Patent Document 1, it is described that both ends of the building board are zigzag along the convex pattern.

Further, in Patent Document 2, on one end of the building board, the end of the half-brick portion is aligned with the end of all the bricks, and on the other end, the end of all the bricks is vertically aligned with the end of the whole brick. In addition to providing joints, it is described that the vertical joints are not provided at the ends of the half-brick portions, but are enlarged by the amount of the vertical joints and aligned with the vertical joints at the ends of all the brick portions.

However, since the building board of Patent Document 1 has a combination of zigzag concavo-convex portions at both ends, the concavo-convex portions of the adjacent building boards are accurately matched, and the convex portions are inserted into the concave portions and fitted together. There were problems such as that the work was difficult and that construction defects were likely to occur.

In the building board of Patent Document 2, when a half-brick portion on one side and a half-brick portion on the other side of a plurality of building boards arranged in parallel are aligned with each other and joined together, the half-brick portions on both sides are joined together. All brick patterns can be displayed together.

However, the seams between the half-brick portion on one side and the half-brick portion on the other side cannot be eliminated, and the seams are conspicuous.
