PROBLEM TO BE SOLVED: To provide a fixture of a reinforcement cage which can efficiently suppress the propagation of displacement in crossing regions caused by a twist between a main reinforcement and a reinforcement when an external force acts at the transfer of the reinforcement cage in a plurality of the crossing regions in a circumferential direction of the reinforcement cage which are set in advance, and reliably prevent the deformation of the reinforcement cage.SOLUTION: As second fixtures 3 for fixing a main reinforcement 11a and a reinforcement 12a of a reinforcement cage in a plurality of second crossing regions 20 which are set in advance, there are provided: a main-reinforcement side constraint implement 31 having a main reinforcement constraint part 311 which continuously constrains the main reinforcement 11a from an anti-reinforcement 12a side over a wide range in an axial line direction of the main reinforcement, and is formed into a substantially-U shaped cross section; a reinforcement side constraint implement 32 having a reinforcement constraint part 321 which continuously constrains the reinforcement 12a from an anti-main reinforcement 11a side over a wide range in an axial line direction of the reinforcement, and is formed into a substantially-U shaped cross section; and a fastener 33 which fastens both the constraint implements 31, 32 with bolts 331 and nuts 332 which are inserted into four corners of the constraint implements.SELECTED DRAWING: Figure 11
【課題】鉄筋籠の周方向の予め設定された複数の交叉部位において鉄筋籠の移動時などに外力が作用した際の主筋と補強筋との間のねじれによる交叉部位でのずれの伝播を効率よく抑えて、鉄筋籠の変形を確実に防止することができる鉄筋籠の固定金具を提供する。【解決手段】鉄筋籠の主筋１１ａ及び補強筋１２ａを予め設定された複数の第２交叉部位２０において固定する第２固定金具３として、主筋１１ａをその軸線方向の広範囲に亘って反補強筋１２ａ側から連続的に拘束する断面略Ｕ字状の主筋用拘束部３１１を有する主筋側拘束具３１と、補強筋１２ａをその軸線方向の広範囲に亘って反主筋１１ａ側から連続的に拘束する断面略Ｕ字状の補強筋用拘束部３２１を有する補強筋側拘束具３２と、両拘束具３１，３２をその四隅に挿通されるボルト３３１とナット３３２とにより締結する締結具３３とを備える。【選択図】図１１
