REPAIR METHOD OF BUILDING
PROBLEM TO BE SOLVED: To provide a repair method of a building for constructing a new CFT column by utilizing effectively the structure of the CFT column and tightly rejoining cut ends of an existing CFT column portion remaining on upper and lower sides of a cutting portion.SOLUTION: A repair method of a building in which existing CFT columns in an existing building are cut and cut ends of existing CFT column portions 2, 3 remaining above and below a cutting portion are directly or indirectly rejoined to construct a new CFT column. The new CFT column is constructed by performing: a space forming step of forming grout filling spaces 2a, 3a between ends of the upper and lower CFT column portions 2, 3 to be rejoined; a welding step of welding steel pipes 7 at the ends of the upper and lower CFT column portions 2, 3 after the space forming step; and a grout filling step of filling the grout filling spaces 2a, 3a with grout after the welding step.SELECTED DRAWING: Figure 3
【課題】ＣＦＴ柱の構造を有効に利用し、切断箇所の上下に残存する既存ＣＦＴ柱部分の切断端部どうしを強固に再接合して新たなＣＦＴ柱を構築する建物の改修方法の提供。【解決手段】既存建物にある既存ＣＦＴ柱を切断し、切断箇所の上下に残存する既存ＣＦＴ柱部分２、３の切断端部どうしを直接的又は間接的に再接合して新たなＣＦＴ柱を構築する建物の改修方法であって、再接合の対象となる上下のＣＦＴ柱部分２、３の端部間に亘ってグラウト充填用空間２ａ、３ａを形成する空間形成工程と、空間形成工程後に、上下のＣＦＴ柱部分２、３の端部の鋼管７どうしを溶接する溶接工程と、溶接工程後に、グラウト充填用空間２ａ、３ａにグラウトを充填するグラウト充填工程と、を実行して新たなＣＦＴ柱を構築する。【選択図】図３
