PROBLEM TO BE SOLVED: To provide a simple reinforcing bar connecting structure which enables to easily connect reinforced units to each other at a lower cost by reduction of the number of parts, material cost, and production cost, and also provide a method for producing the reinforced unit suitable for realizing the reinforcing bar connecting structure. SOLUTION: Respective one ends of main reinforcing bars 2a, 2b of a first reinforced unit 1 are bent in a crank shape to form bent parts 5a, 5b. Extension parts 6a, 6b formed by extension of the bent part 5a and linear parts 10a, 10b of a second reinforced unit 7 are joined in a bundle and the first reinforced unit 1 and the second reinforced unit 7 are almost linearly connected. Joining bars 3 are joined to the main reinforcing bars 2a, 2b in a ladder shape, thereafter one end is bent in a crank shape to produce the first reinforced unit 1. COPYRIGHT: (C)2005,JPO&NCIPI
