REINFORCED-CONCRETE PERFORATED BEAM
PROBLEM TO BE SOLVED: To provide a reinforced-concrete perforated beam much excellent in aspects of cost reduction and workability.SOLUTION: A reinforced-concrete perforated beam 2 having an open hole 3 forming an opening comprises: beam main reinforcements 9, 10A and 10B which are the reinforcements extending along the beam's span direction and which are arranged in the beam's width direction at predetermined intervals; and hoop reinforcements 8A and 8B and 8C stretched around the beam main reinforcements. The beam main reinforcements 10A and 10B are arranged below the open hole 3 and the beam main reinforcement 10B is arranged outside a region W of the beam in the beam width direction.SELECTED DRAWING: Figure 1
【課題】より一層コスト面及び施工性の面において優れた鉄筋コンクリート有孔梁を提供する。【解決手段】開口を形成する貫通孔３を有する鉄筋コンクリート有孔梁２は、梁のスパン方向に沿って延びる鉄筋であって梁の幅方向に所定間隔を置いて配置される梁主筋９、１０Ａ、１０Ｂと、これら梁主筋に掛け回されるフープ筋８Ａ、８Ｂ、８Ｃと、を備えている。梁主筋１０Ａ、１０Ｂは、貫通孔３に対し下側に配置されるとともに、梁主筋１０Ｂは、梁幅方向において梁の領域Ｗの外側に配置されている。【選択図】図１
