REINFORCEMENT STRUCTURE FOR REINFORCED CONCRETE BEAM WITH THROUGH-HOLE

摘要

PROBLEM TO BE SOLVED: To provide a beam reinforcement structure that improves a reinforcement structure applied to a reinforced concrete beam with a through-hole.SOLUTION: A reinforcement structure 12 for a reinforced concrete beam 10 having a plurality of upper main reinforcements 16 and a plurality of lower main reinforcements 18 and having a through-hole 22 provided between both the upper and lower main reinforcements includes a steel plate 24 that is vertically provided between both the upper and lower main reinforcements. The steel plate 24 has a hole 28 which is opened on both surfaces of the steel plate 24 and which defines the trough-hole 22 or surrounds the periphery of the through-hole 22, and a plurality of protrusions 30 which are provided on both surfaces of the steel plate 24, respectively.
