JOINT STRUCTURE BETWEEN COLUMNS AND BEAMS AND CONSTRUCTION METHOD OF JOINT STRUCTURE BETWEEN COLUMNS AND BEAMS
To provide a joint structure between columns and beams that can ensure the shear transmission performance and axial force transmission performance of columns and improve the efficiency of concrete placing work, and a construction method of the joint structure between columns and beams.SOLUTION: In a joint structure 100 of columns and beams, a column 4 has a steel pipe 41 extending in the vertical direction, a plurality of joint reinforcing bars 42 arranged inside the steel pipe 41 and extending in the vertical direction, a plurality of vertical reinforcing bars 47 arranged inside the steel pipe 41 and extending in the vertical direction, and a plurality of shear reinforcing bars 48a and 48b for bundling the plurality of vertical reinforcing bars 47. The joint structure comprises a closing member 2 that communicates with the steel pipe 41 and is provided so as to surround the joint reinforcing bar 42 that protrudes from the column 4, a joint beam 1X that is joined to the beam 1, and a concrete portion 49 filled inside the steel pipe 41 and inside the closing member 2. The vertical reinforcing bars 47 and the shear reinforcing bars 48a and 48b are arranged so as to overlap the joint beam 1X in a plan view.SELECTED DRAWING: Figure 1
【課題】柱のせん断伝達性能及び軸力伝達性能を確保するとともに、コンクリート打設作業の効率化を図ることができる柱と梁との接合構造及び柱と梁との接合構造の施工方法を提供する。【解決手段】柱と梁との接合構造１００では、柱４は、鉛直方向に延びる鋼管４１と、鋼管４１の内部に配置され、鉛直方向に延びる複数の接合鉄筋４２と、鋼管４１の内部に配置され、鉛直方向に延びる複数の鉛直補強筋４７と、複数の鉛直補強筋４７を束ねる複数のせん断補強筋４８ａ，４８ｂと、を有し、鋼管４１に連通し、柱４から突出する接合鉄筋４２を囲繞するように設けられたふさぎ部材２と、梁１に接合される接合梁１Ｘと、鋼管４１の内部及びふさぎ部材２の内部に充填されたコンクリート部４９と、を備え、鉛直補強筋４７及びせん断補強筋４８ａ，４８ｂは、平面視で、接合梁１Ｘと重なって配置されていることを特徴とする。【選択図】図１
