ANCHORED STRUCTURE OF BEAM MAIN REINFORCEMENT AT COLUMN-TO-BEAM JUNCTION

摘要

PROBLEM TO BE SOLVED: To enable improving anchoring workability that was difficult to attain, while keeping the anchoring property of beam main reinforcement sufficiently high. ;SOLUTION: At the junction between the column 1 of a reinforced concrete structure and beams 2 arranged to cross the column 1 in cruciform, a plurality of beam main reinforcements 3 arranged inside column main reinforcements 4 in such a way as to cross one another in an X-Y shape and projecting from the ends of the beams 2 are anchored to the inside of the column via a joint. In this case, the joint comprises four strips of anchoring metal fittings 10, which are located in the inside surrounded by the column main reinforcements 4, and in which fitting grooves are formed that can be assembled into an well crib shape, and a plurality of holes through which the beam main reinforcements 3 are passed are formed in the anchoring metal fittings 10. The ends of the beam main reinforcements 3 which project from the beams 2 facing the anchoring metal fittings 10 are passed through the holes, and a plurality of anchoring nuts 16 that are screwed to the beam main reinforcement 3 are secured to both sides of each hole, and the anchoring metal fittings 10 are assembled into the well crib shape and secured to one another to anchor each beam main reinforcement 3 inside the column 1.;COPYRIGHT: (C)1999,JPO
