JOINT STRUCTURE OF REINFORCING BAR, PLACING JOINT METHOD FOR REINFORCED CONCRETE STRUCTURAL BODY, AND JOINT METHOD FOR PRECAST CONCRETE MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a joint structure of reinforcing bars capable of being adopted also to a site on which high tension or compressive force acts without scattering a joint position, a placing joint method for a reinforced concrete structural body for efficiently arranging the reinforcing bars and casting concrete by using the joint structure, and a joint method for precast concrete members.;SOLUTION: Two reinforcing bars 1 and 2 bent in a U-shape and having curve sections and parallel straight sections continued to them overlap each other in the vicinity of the curve sections 1a and 2a, and two reinforcing bars are so arranged that the straight sections 1b and 2b are extended to the opposite sides on the same straight line from the overlapped parts. Restraining reinforcing bars 5 are arranged to the outside of the overlapped parts so as to wind them on the two parallel straight sections, and transverse reinforcing bars 3 are arranged to the insides of the overlapped parts at right angles to the straight sections.;COPYRIGHT: (C)2000,JPO
