摘要： PROBLEM TO BE SOLVED: To improve the arranging workability of reinforcements, by providing one continuous reinforcement rod composed of a part extending along the upper end of a beam member, a slant part against the beam axis, extending from the upper end of the support ends to the lower end, and a part extending along the lower end to arrange from the upper end to the lower end through the support ends. SOLUTION: A reinforcing rod 2 in this structure is made of a continuous rod composed of a part 21 parallel to the upper end, a slant part 22 against a beam axis, extending from the upper end of the support end 10 to the lower end thereof, and a part 23 parallel to the lower end. Since a diagonal tensile stress generated in the concrete is distributed to the direction from the center of member to the ends thereof and from the lower side to the upper side at the nearby position of the support ends 10, the reinforcements are arranged in this distributing direction and hence, the support ends are effectively reinforced. Since the end of the beam member is reinforced by one reinforcing rod 2, the beam dispenses with closed type shearing reinforcements in notched parts and hence, arrangement of reinforcements is simplified and the arranging workability of reinforcements is improved.
