BAR ARRANGEMENT STRUCTURE OF REINFORCED CONCRETE BEAM AND BAR ARRANGEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a bar arrangement structure of a reinforced concrete beam which has no necessity for processing a hook at a stirrup, does not increase the number of part items, and can easily perform assembling work.SOLUTION: A bar arrangement structure 1 of a reinforced concrete beam comprises upper-end main reinforcements 3, 4, lower-end main reinforcements 5, 6, and stirrups 7 which are arranged in a beam length direction at constant intervals in a state of surrounding the main reinforcements 3 to 6. The stirrups 7 comprise U-shaped first stirrups 8 which are joined to the main reinforcements 3 to 6, respectively, by full-strength welding, and second stirrups 9 which are covered on the upper-end main reinforcements 3, 4 in a state of being bridged between the upper-end main reinforcements, and fixed to the main reinforcements 3, 4.SELECTED DRAWING: Figure 1
