PROBLEM TO BE SOLVED: To provide a reinforcement arranging method of a concrete beam excellent in reduction of the quantity of reinforcements used and simplification of the reinforcements and achieving shortening of construction term, stabilization of quality and reduction of costs by standardizing sizes without causing problems related to reliability, strength and structural specification of reinforcement joint position. SOLUTION: The reinforcement arranging method of a concrete beam is applied to a steel framed reinforced concrete beam or a reinforced concrete beam 3 constituting a column-beam framed body 1 of a rigid-frame structure. An upper end reinforcement 12 and a lower end reinforcement 13 comprises a pair of reinforcements A<SB>1</SB>, A<SB>2</SB>with widened diameter heads and an intermediate reinforcement B joined to them. The reinforcements A<SB>1</SB>, A<SB>2</SB>with the widened diameter heads each have a widened diameter head Aa provided on one end, and the widened diameter head Aa is embedded in the concrete of the reinforced concrete column 2. The reinforcements A<SB>1</SB>, A<SB>2</SB>with the widened diameter heads are prepared by a reinforcement manufacturer as a standardized product of a standard size. COPYRIGHT: (C)2009,JPO&INPIT
