CORNER STRUCTURE OF STAIRCASE AND METHOD FOR CONSTRUCTING CORNER STRUCTURE OF STAIRCASE

PROBLEM TO BE SOLVED: To provide a corner structure of staircase and a method for constructing the corner structure of staircase that can increase workability.SOLUTION: A corner structure comprises a corner member 401. The corner member 401 integrally has an upstairs side parting material 41 and a downstairs side parting material 42 butted against each other in L-shape. The upstairs side parting material 41 and the downstairs side parting material 42 cover a boundary part between a rear face 3b and a right surface 3a of an outside corner 31 in a skeleton 3 and a top face of a step board 151. Because the corner member 401 is one member, workability can be increased compared with the case in which two members are individually arranged in the outside corner 31.SELECTED DRAWING: Figure 3 【課題】施工性を向上させることができる階段のコーナー構造及び階段のコーナー構造の施工方法を提供する。【解決手段】コーナー構造はコーナー部材４０１を備える。コーナー部材４０１は、Ｌ字状に突き合わされた階上側見切り材４１及び階下側見切り材４２を一体的に有する。階上側見切り材４１及び階下側見切り材４２は、躯体３の出隅３１における後面３ｂ及び右面３ａと踏板１５１の上面との境界部分を被覆する。コーナー部材４０１は１部材なので、出隅３１に対して２部材を個別に配置する場合に比べて、施工性を向上させることができる。【選択図】図３
