Abstract

PURPOSE: To maintain reinforcing bars with high strength, and facilitate quality control and construction at a site by caulking the butt welding of ring bars and the spot welding of crossed part of the ring bars and branch bars. CONSTITUTION: A high strength bar is circled at least once or more round into an annulus ring form, both the ends of which are extended in the tangential direction in order to form an outer ring bar 1 as a branch bar 1a. Then, the bar is circled into a smaller diameter than that of the outer ring bar 1, both the ends of which are also extended in the tangential direction so as to form an inner ring bar 2 as a branch bar 2a. Subsequently, the outer ring bar 1 and inner ring bar 2 are set concentrically, followed by caulking each crossed part into an integral relation by a caulking member 3 such as metal or plastics.
