GROUTLESS COUPLING MECHANISM OF OPPOSITE REINFORCEMENT BAR AND FIXATION HARDWARE WITH GROUTLESS SLEEVE LEG ACCORDING TO MECHANISM
To provide a groutless coupling mechanism of opposite reinforcement bars that a reinforcement bar pressing force due to a machine screw is uniformed even the sleeve is not filled with the grout and accordingly that eliminates a necessity of various control with regard to the filling.SOLUTION: A sleeve 2 is an austemper nodular graphite cast iron product and a reinforcement bar is an irregular shape reinforcement bar 1 having a pitch of its projection 7 formed while being constantly maintained. An arrangement interval of machine screws 3 is a constant pitch to be an integral multiple of the pitch between the projections and a part having a tip pressing the reinforcement bar 1 is a projection apex part 7t. A pressure bearing seat is arranged at substantially opposite part of a screw hole 4 of a sleeve 2 in left and right distribution arc shape, the part pressurizing the reinforcement bar by this pressure bearing seat is also the projection apex part 7t of the reinforcement bar 1, configures a substantially 3 points support having a high stability in a circumferential direction along with the machine screw 3 and is the as-cast surface integrally molded to this sleeve. The sleeve 2 is not filled with the grout.SELECTED DRAWING: Figure 1
【課題】スリーブにグラウトが充填されなくても、小ねじによる鉄筋押圧が均一化され、したがって、充填に関する各種管理が必要でなくなる対向鉄筋のグラウトレスカップリング機構を提供する。【解決手段】スリーブ２はオーステンパー球状黒鉛鋳鉄製品であり、鉄筋はその突起７のピッチが一定に保って形成された異形鉄筋1である。小ねじ３の配置間隔は突起間ピッチの整数倍とした定ピッチとされ、その先端により鉄筋1が押圧される部位は突起頂部位７ｔとされる。受圧座はスリーブ２の螺進孔４の略対向部位に左右振り分け円弧状に設けられ、この受圧座により鉄筋が受圧される部位も、鉄筋1の突起頂部位７ｔとされ、小ねじ３とともに周方向の安定度の高い略三点支持をなしており、このスリーブに一体成形の鋳放し面とされる。スリーブ２にはグラウトが充填されていない。【選択図】図１
