A structure as described in Japanese Patent No. 853 is known.
この従来構造は、外壁材の周側面に予め防水材が設けら
れており、この防水材が互いに密着するように外壁材が
縦及び横方向に連続して配列されたものであった。In this conventional structure, a waterproof material is preliminarily provided on the peripheral side surface of the outer wall material, and the outer wall materials are continuously arranged in the vertical and horizontal directions so that the waterproof materials are in close contact with each other.
即ち、縦及び横方向に隣接する外壁材の接合部は、全て
防水材の密着のみによって防水効果が確保されていた。That is, the waterproof effect is secured only at the joints of the outer wall materials adjacent to each other in the vertical and horizontal directions only by the close contact of the waterproof material.

の低下を招くことになっていた。(Problems to be solved by the invention) However, in such a conventional joint structure of outer wall materials, since the waterproof material is exposed on the outer surface of the building, the appearance of the building is impaired. Moreover, the deterioration of the waterproof material was expected to be accelerated because it was easily wet by rainwater. Moreover, since the waterproof effect of the exterior material joint portion depends entirely on the adhesion between the waterproof materials, the deterioration of the waterproof material directly leads to a decrease in the waterproof effect.
