JOINING STRUCTURE OF MUTUAL COLUMNS AND BUILDING
PROBLEM TO BE SOLVED: To provide a joining structure of mutual columns and a building, capable of restraining outer surface buckling.SOLUTION: A joining structure of mutual columns comprises: a main reinforcement part 70 for joining a first column 1 and a second column 2 via a stress switching part 5, arranging the stress switching part 5 on a lower part 2A of the second column 2 and the outer peripheral side of the lower part 2A of the second column 2 and extending by projecting in the vertical direction from a concrete part 13 by continuing with a column main reinforcement 11; a first steel pipe 50 for wholly surrounding the main reinforcement part 70 and arranged over the total length in the vertical direction; a spiral hoop reinforcement 60 arranged on the inner peripheral side of the first steel pipe 50 and the outer peripheral side of the second column 2 and extending in a spiral shape toward the vertical direction; and a filled concrete part 80 filled between an inner peripheral surface of the first steel pipe 50 and an outer peripheral surface of the second column 2.
【課題】面外座屈を抑制することができる柱同士の接合構造及び建築物を提供する。【解決手段】柱同士の接合構造は、第一柱１と第二柱２とは、応力切替部５を介して接合されており、応力切替部５は第二柱２の下部２Ａと、第二柱２の下部２Ａの外周側に配置され、柱主筋１１と連続してコンクリート部１３から鉛直方向に突出して延びる主筋部７０と、主筋部７０を全て囲繞するとともに、鉛直方向全長にわたって配置された第一鋼管５０と、第一鋼管５０の内周側に、かつ、第二柱２の外周側に配置され、鉛直方向に向かってらせん状に延びるスパイラルフープ筋部６０と、第一鋼管５０の内周面と第二柱２の外周面との間に充填された充填コンクリート部８０と、を備えることを特徴とする。【選択図】図２
