PROBLEM TO BE SOLVED: To provide a bar arrangement method for beam reinforcements, capable of reducing a time required for a bar arrangement work.SOLUTION: A bar arrangement method 1 for beam reinforcements includes: steps S1, S2 of building plate materials 61 so as to abut on front end faces of end side beam main reinforcements 21A already arranged; a step S3 of assembling a preassembled beam reinforcement unit 60 by temporarily assembling beam reinforcements 20 including central side beam reinforcements 21B on a ground in advance, lifting up the preassembled beam reinforcement unit 60 by a crane, and installing it on the opposite side relative the end side beam main reinforcements 21A already bar-arranged with the plate materials 61 therebetween so that the central side beam reinforcements 21B of the preassembled beam reinforcement unit 60 abuts on the plate materials 61; a step S4 of removing the plate materials 61; and steps S6 to 8 of joining the beam main reinforcements 21A, 21B facing to each other by mechanical joints 30. |
