CONSTRUCTION METHOD FOR COLUMN-BEAM JOINT STRUCTURE, AND JOINT MEMBER

SAGAWA TAKAYUKI

To provide a construction method for a column-beam joint structure and a joint member capable of easily performing concrete installation work.SOLUTION: A construction method for a column-beam joint structure comprises: a lower side steel pipe installation of installing a lower side steel pipe 11a so as to extend in the vertical direction; a joint member installation of disposing a joint member 3 which has a plurality of joint reinforcements 32 extending in the vertical direction, a covering steel pipe 31 disposed so as to surround the outside of a vertically intermediate portion of the plurality of joint reinforcements 32, a joint concrete portion 33 charged into the covering steel pipe 31, and a joint beam 34 joined to the covering steel pipe 31, so that the covering steel pipe 31 becomes coaxial with the lower side steel pipe 11a at the upper side of the lower side steel pipe 11a; an upper side steel pipe installation of coaxially installing an upper side steel pipe 11b at the upper side of the covering steel pipe 31; and a lower side steel pipe concrete installation of installing concrete from an installation hole 51 which is formed to penetrate the plate thickness of the lower side steel pipe 11a at the upper part of the lower side steel pipe 11a.SELECTED DRAWING: Figure 7
