JUNCTION STRUCTURE BETWEEN COLUMN-BEAM JOINT PART AND COLUMN, RIGID-FRAME VIADUCT, CONSTRUCTION METHOD FOR JUNCTION STRUCTURE BETWEEN COLUMN-BEAM JOINT PART AND COLUMN, AND PRECAST CONCRETE MEMBER
PROBLEM TO BE SOLVED: To prevent an adverse effect on a plastic hinge between a column and a beam, even when a junction structure between a column-beam joint part and the column is constructed by a precast construction method.SOLUTION: A junction structure between a column-beam joint part and a column includes: a PC joint part constituent member 60 having concrete 66 forming a column-beam joint part 61 and a column part 63, and a sheath pipe 67 embedded in concrete 66 at a portion between a top end of the column-beam joint part 61 and a bottom end of the column part 63; a PC column member 30 having second concrete 32 below the column part 63, a main reinforcement 31 extending in a vertical direction inside the second concrete 32, and a tubular sleeve joint material 33 provided at a top end of the main reinforcement 31; a vertical reinforcement 81 inserted into the sheath pipe 67 and protruding from a bottom end of the sheath pipe 67 and inserted into the sleeve joint material 33; a filler material 83 filled in the sleeve joint material 33; a filler material 82 filled in the sheath pipe 67; and a joint material 84 provided between the PC column member 30 and the column part 63.SELECTED DRAWING: Figure 3
【課題】プレキャスト工法によって柱梁仕口部−柱の接合構造を構築しても、柱と梁との間の塑性ヒンジに悪影響を及ばさないようにする。【解決手段】柱梁仕口部−柱の接合構造は、柱梁仕口部６１及び柱部６３を構成するコンクリート６６と、柱梁仕口部６１の上端から柱部６３の下端にかけてコンクリート６６に埋設されたシース管６７と、を有するＰＣ仕口構成部材６０と、柱部６３の下の第二コンクリート３２と、第二コンクリート３２内部で上下方向に延在した主筋３１と、主筋３１の上端に設けられた管状のスリーブ継手材３３と、を有するＰＣ柱部材３０と、シース管６７に挿入されているとともに、シース管６７の下端から突き出てスリーブ継手材３３に差し込まれた縦方向鉄筋８１と、スリーブ継手材３３に充填された充填材８３と、シース管６７に充填された充填材８２と、ＰＣ柱部材３０と柱部６３との間に設けられた目地材８４と、を備える。【選択図】図３
