To provide a reinforcing bar fixture capable of preventing a problem such as loosening due to rotation of a main bar when the main bar is placed orthogonally to the right-angled corner of the shear reinforcement to fix the intersection.SOLUTION: A reinforcing bar fixture 100 fixes an intersection where a main bar VR with a pair of reinforcing rib VRRs protruding along the longitudinal direction of the reinforcing bar is placed orthogonally to the corner formed by a bent shear reinforcement HR. A shear reinforcement bar holding area 111 of a reinforcing bar fixture body 110 is formed in a U-shape via an arc-shaped shear reinforcement contact area where shear reinforcement HR contacts. Main bar holding areas 112 and 113 are formed in an L-shape by expanding at an almost right angle via an arc-shaped main bar contact area where each main bar VR contacts. In a first main bar holding area 112 and a second main bar holding area 113, rib engaging recesses 112r and 113r that engage with the reinforcing rib VRR of the main bar VR are provided in the main bar contact area.SELECTED DRAWING: Figure 1
【課題】主筋を剪断補強筋の直角コーナーに直交配置して交差部分を固定する際に、主筋の自転回動による緩み等の不具合を防止する鉄筋固定具を提供すること。【解決手段】鉄筋長手方向に沿って突起した一対の補強用リブＶＲＲを有する主筋ＶＲを剪断補強筋ＨＲが屈曲して形成するコーナーに直交配置してなる交差部分を固定し、鉄筋固定具本体１１０の剪断補強筋抱持領域１１１が剪断補強筋ＨＲに当接する円弧状の剪断補強筋当接部位を介してＵ字状に形成され、主筋抱持領域１１２、１１３がそれぞれ主筋ＶＲに当接する円弧状の主筋当接部位を介して略直角に拡開してＬ字状に形成され、第一主筋抱持領域１１２及び第二主筋抱持領域１１３の主筋当接部位に主筋ＶＲの補強用リブＶＲＲと係合するリブ係合凹部１１２ｒ、１１３ｒを備えている鉄筋固定具１００。【選択図】図１
