EXTERIOR WALL STRUCTURE AND DRAINAGE STRUCTURE FOR BUILDING USING THE SAME

To provide: exterior wall structure excellent in appearance without impairing the design of a building by providing a drainage space inside the exterior wall for draining rainwater collected in an eaves gutter or an inner gutter in the vertical direction; and drainage structure for buildings using the same.SOLUTION: Exterior wall structure has alternating mountain and valley portions extending in the vertical direction. The right and left side edges of face plate sections 11, 21 are bent in their front and back directions. Furthermore, mountain-shaped exterior material 1 and valley-shaped exterior material 2 are connected, having side edge molding sections 13, 23 whose tips are folded back toward the face plate sections 11, 21, respectively. The back side of the mountain-shaped exterior material 1 and/or the front side of the valley-shaped exterior material 2 are used as a drainage space 3.SELECTED DRAWING: Figure 1 【課題】軒樋や内樋に集められた雨水を高さ方向へ流すことができる排水空間が外壁内部に備えられ、建築物の意匠を損なうことなく、美観に優れた外壁構造、及びそれを用いた建築物の排水構造を提供する。【解決手段】本発明は、高さ方向に延在する山部、谷部が交互に形成される外壁構造であって、面板部１１，２１の左右側縁がその表裏方向へ折り曲げられ、更にその先端を前記面板部１１，２１側へ折り返した側縁成形部１３，２３を設けた山状外装材１、谷状外装材２を接続し、前記山状外装材１裏面側及び／又は前記谷状外装材２の表面側を排水空間３としたことを特徴とする。【選択図】図１
