SHEAR REINFORCEMENT METHOD AND SHEAR REINFORCEMENT STRUCTURE
To provide a shear reinforcement method and a shear reinforcement structure which enable efficient arrangement of shear reinforcements for suppressing enlargement of a crack width.SOLUTION: A flat slab 20 is composed of reinforced concrete having upper end reinforcements 21 and lower end reinforcements 22, and extends in a horizontal direction. The flat slab 20 includes engagement parts 31a engaged with the upper end reinforcements 21, reinforcement parts 31b extending to the vicinity of the lower end reinforcements 22 from the engagement parts 31a, and a plurality of shear reinforcements 30 having fixing plates 32 provided on the lower ends of the reinforcement parts 31b. The engagement parts 31a of the shear reinforcements 30 are engaged with the upper end reinforcements 21, the shear reinforcements 30 are suspended from the upper end reinforcements 21, then concrete is placed in a non-engagement state of the reinforcement parts 31b of the shear reinforcements 30 and the fixing plates 32, and thereby the flat slab 20 is constructed.SELECTED DRAWING: Figure 1
【課題】ひび割れ幅の拡大を抑制するせん断補強筋を効率的に配置することができるせん断補強方法及びせん断補強構造を提供する。【解決手段】フラットスラブ２０は、上端筋２１と下端筋２２とを備えた鉄筋コンクリートで構成され水平方向に延在する。フラットスラブ２０は、上端筋２１に掛止する掛止部３１ａと、掛止部３１ａから下端筋２２の近傍まで延在する補強部３１ｂと、補強部３１ｂの下端部に設けた定着プレート３２とを備えた複数のせん断補強筋３０を備える。せん断補強筋３０の掛止部３１ａを上端筋２１に掛止させて、せん断補強筋３０を上端筋２１に吊り下げた後、せん断補強筋３０の補強部３１ｂ及び定着プレート３２を非掛止状態で、コンクリート打設を行なうことにより、フラットスラブ２０を構築する。【選択図】図１
