SCREW TYPE REINFORCEMENT JOINT AND FASTENING CONFIRMATION WASHER
To provide a screw type reinforcement joint in which whether a lock nut is fastened at a prescribed torque can be visually and easily confirmed.SOLUTION: A screw type reinforcement joint comprises male screw portions 1c, 1c provided at ends of a pair of reinforcements 1, 1, a screw cylindrical coupler 2, and a lock nut 3. A fastening confirmation washer 4 is interposed between the coupler 2 and the lock nut 3. The fastening confirmation washer 4 includes a protrusion 4b protruding in a thickness direction in a natural state, and is elastically deformed in a flat shape when applied with a compressive force larger than a prescribed value between both faces.SELECTED DRAWING: Figure 1
【課題】ロックナットが規定トルクで締め付けられているか否かを目視で簡単に確認することができるねじ式鉄筋継手を提供する。【解決手段】一対の鉄筋１，１の端部に設けられた雄ねじ部１ｃ，１ｃと、ねじ筒状のカプラー２と、ロックナット３とを有するねじ式鉄筋継手に適用される。カプラー２とロックナット３との間に締付け確認座金４が介在する。締付け確認座金４は、自然状態で厚み方向に突出する突出部分４ｂを有し両面間に規定値以上の圧縮力が作用することで平坦に弾性変形する。【選択図】図１
