STRUCTURE FOR JOINTING BETWEEN STEEL-PIPE COLUMN OR STEEL COLUMN AND BEAM REINFORCEMENT

PROBLEM TO BE SOLVED: To provide a structure for joining a beam reinforcement for beam construction to a steel-pipe column or a steel column without forming a horizontal haunch, which not only enhances the reliability of jointing but also eliminates the possibility of a decrease in strength of the beam reinforcement and extension of a construction period. SOLUTION: The beam reinforcement for the beam construction serves as a screw reinforcement; a screw reinforcement through-hole (2), whose diameter is equal in size to/slightly larger than that of the screw reinforcement, is precedently drilled in an anchor plate part (1) to which the beam reinforcement of the steel-pipe column (7) or the steel column (10) is joined; a screw-reinforcement bolt (3) is passed through the through-hole (2); a screw-reinforcement locking nut (4) is screw-fitted from an end serving as one inside of the bolt (3), and a screw-reinforcement coupler (5) is screw-fitted from an end serving as the other outside of the bolt (3), so as to be fastened for fixation to the plate part (1); and the screw reinforcement is screwed into the coupler (5) of the column (7) or (10) into which concrete is poured on the site of the execution of work, so as to be joined to the column (7) or (10).
