SELF-REPAIRING STRUCTURE OF COLUMN-BEAM JOINT PART
To provide a self-repairing structure of a column-beam joint part applicable to the column-beam joint part to which beams are attached in a cross shape in a plan view.SOLUTION: A self-repairing structure 10 includes: a column 2 made of reinforced concrete; a beam 3 made of reinforced concrete joined to the column 2; and a repairing tool 11 fixed to a corner part defined by the column 2 and the beam 3. The repairing tool 11 includes: a sheet 12 fixed to the corner part; and a repairing material 13 having fluidity held by the sheet. When a crack is generated along the diagonal line of a column beam joint 1 at the time of an earthquake of a predetermined scale or more, the repairing material 13 penetrates into the crack and hardens after the earthquake, so that the crack is repaired.SELECTED DRAWING: Figure 3
【課題】平面視で十字状に梁が取り付いた柱梁接合部にも適用可能な柱梁接合部の自己修復構造を提供する。【解決手段】自己修復構造１０は、鉄筋コンクリート造の柱２と、柱２に接合する鉄筋コンクリート造の柱梁３と、柱２及び梁３によって画成される隅部に固定された補修具１１を備える。補修具１１は、隅部に固定されるシート１２と、シートに保持された流動性を有する補修材１３とを含む。所定規模以上の地震時に柱梁接合部１の対角線に沿ってひび割れが生じると、補修材１３がこのひび割れに浸入して地震後に硬化するため、ひび割れが補修される。【選択図】図３
