地と略同じ幅とされている構造とする。[0010] The lateral end of the exterior material is formed in an uneven shape so that the block shape of the end in the block-shaped pattern on the surface of the exterior material is not divided by the vertical joints and becomes a normal block shape. ing. In addition, a joint material having elasticity and waterproofness and having a width larger than the pseudo joint is bonded to one lateral end surface of the exterior material in advance, and the exterior materials are adjacent to each other in the horizontal direction and are formed on the ground. In the fixed state,
The joint material bonded to one of the exterior materials adjacent in the lateral direction is in close contact with the lateral end surface of the other exterior material, and the finished width of the vertical joint formed by the joint material is the pseudo joint in the vertical direction. It is assumed to be a structure having substantially the same width as.

【００１１】こうすれば、従来のように外装材の横方向
端部において表面のブロック状模様が縦目地により分断
されることがないので、意匠性を高めることができる。In this way, since the block-shaped pattern on the surface is not divided by the vertical joints at the lateral ends of the exterior material as in the prior art, the design can be improved.
