To provide a joint structure of columns having a high pull-out bearing force.SOLUTION: A stress switching part 5 of a joint structure 100 of columns includes: a base plate 25 which is provided on the lower end of a second column 2 and has a projection base part 26 projecting outward from the outer peripheral surface of the second column 2; a main reinforcement part 30 which is arranged on the outer peripheral side of a lower part 2d of the second column 2, and is continuous to the column main reinforcement and projects and extends to a vertical direction from a concrete part; a joint steel pipe 40 arranged so as to surround all of the main reinforcement part 30; a filling concrete part 50 filling the inside the joint steel pipe 40; and a pull-out force resistor element 60 which is provided on at least any one of the lower part 2d of the second column 2, the main reinforcement part 30 and the joint steel pipe 40 and resists a force of pulling out the second column 2 from the joint steel pipe 40. In the structure the pull-out force resistor element 60 is arranged so as to cross a line L connecting an upper end 40u of the joint steel pipe 40 and an outer edge part 26a of the projection base part 26 of the base plate 25, supposing that cracks occur on the line L.SELECTED DRAWING: Figure 2
【課題】引抜き耐力の高い柱同士の接合構造を提供する。【解決手段】柱同士の接合構造１００の応力切替部５は、第二柱２の下端部に設けられ、第二柱２の外周面から外方に突出する突出ベース部２６を有するベースプレート２５と、第二柱２の下部２ｄの外周側に配置され、柱主筋と連続してコンクリート部から鉛直方向に突出して延びる主筋部３０と、主筋部３０を全て囲繞するように配置された接合鋼管４０と、接合鋼管４０内に充填された充填コンクリート部５０と、第二柱２の下部２ｄ、主筋部３０及び接合鋼管４０の少なくともいずれかに設けられ、第二柱２が接合鋼管４０から引き抜かれる力に抵抗する引抜き力抵抗要素６０と、を備え、縦断面で、接合鋼管４０の上端部４０ｕとベースプレート２５の突出ベース部２６の外縁部２６ａとを結ぶ線Ｌ上にひび割れが発生するものと仮定し、引抜き力抵抗要素６０は線Ｌと交差するように配置されていることを特徴とする。【選択図】図２
