REINFORCEMENT INTERSECTION FASTENER
PROBLEM TO BE SOLVED: To provide a reinforcement intersection fastener that firmly fastens a reinforcement intersection such as an intersection of a first reinforcement and a second reinforcement of a reinforcement cage disposed in a concrete mold when constructing a reinforced concrete structure.SOLUTION: A U-shaped bent part 12 of a U-bolt 1 is engaged with a first reinforcement 4 that is one of reinforcements to be fastened, and an arc-formed bent part 13 is engaged with a second reinforcement 5 that is the other of the reinforcements to be fastened. While keeping a roughly U-shaped bent part 31 of a fastening plate 3 in contact with the first reinforcement 4 to be fastened, as if to wrap around the reinforcement, both male screw parts 11, 11 of the U-bolt 1 is inserted into insertion holes 33, 33 formed on both flange parts 32, 32 of the fastening plate 3, and nuts 2, 2 are screwed on both screw parts 11, 11, thus firmly fastening an intersection between the first reinforcement 4 and the second reinforcement 5. An inner depth of the bent part 31 of the fastening plate 3 is set such that both flange parts 32, 32 come into contact with the second reinforcement 5 to be fastened, as of the moment when the intersection between the first reinforcement and the second reinforcement is fastened firmly.SELECTED DRAWING: Figure 7
【課題】鉄筋コンクリート構造物施工時における型枠内に配置される鉄筋かごにおける第１鉄筋と第２鉄筋との交差部などの鉄筋交差部の強固な締結が可能な鉄筋交差部締結具の提供。【解決手段】 Ｕボルト１におけるＵ字状折曲部１２を締結すべき一方の第１鉄筋４に係合させ、円弧状折曲部１３を締結すべきもう一方の第２鉄筋５に係合させ、締結プレート３の略Ｕ字状湾曲部３１を締結すべき一方の第１鉄筋４を包み込むように当接させた状態で、Ｕボルト１の両雄ねじ部１１、１１を締結プレート３の両フランジ部３２、３２に備えた挿通孔３３、３３に挿通し、該両雄ねじ部１１、１１にナット２、２を螺合して第１鉄筋４と第２鉄筋５の交差部を強く締結した時点で、両フランジ部３２、３２が締結すべき一方の第２鉄筋５に当接するように前記締結プレート３における湾曲部３１の内側深さが設定されている。【選択図】 図７
