  • the wall structure 1 of this embodiment is a wall structure 1 constructed in a horse-lined manner.
  • the horse-lined wall structure 1 is constructed by arranging a plurality of wall materials 2 in a staggered manner. That is, a plurality of wall materials 2 arranged in the left-right direction and a plurality of wall materials 2 arranged in the left-right direction above them are constructed with a shift of about half a degree in the left-right direction. Therefore, in the wall structure 1 of this embodiment, a straight joint is not formed in the vertical direction on the wall surface.

Moreover, the joint material 4 can guide the water downward so that it flows down. This makes it possible to achieve both a simple wall material shape and waterproofing, resulting in a wall structure 1 that does not use a sealant.
