CONCRETE FORMWORK DISTANCE MAINTAINING CONE
PROBLEM TO BE SOLVED: To provide a P-cone easy-to-be hooked with a spiral part of a separator insertion tool, easy-to-remove after removal of concrete formwork, easy-to-insert a shaft body of the P-cone through a separator through hole and easy-to-remove from cured concrete.SOLUTION: The P-cone has a hooking part 25 having a circular shape in cross section which is formed on a shaft body 20 of the P-cone, and a removal tool mounting part 21 which is formed at the outer side thereof. The hooking part 25 has an hourglass shape with a diameter smaller than that of the removal tool mounting part 21. The hooking part 25 is arranged to allow a spiral part at the front tip of a separator insertion tool to be easily hooked. The P-cone is arranged so that at least a part of the removal tool mounting part 21 is positioned in a thickness area of a concrete formwork.SELECTED DRAWING: Figure 3
【課題】セパレータ挿通工具のらせん部を引掛け容易とし、型枠撤去後のＰコーンの取り外しを容易とし、セパレータ貫通孔からＰコーンの軸体部が挿通しやすいとともに、固まったコンクリートから容易に取り外すことが可能なＰコーンを提供する。【解決手段】Ｐコーンの軸体部２０に、断面形状が円断面形状をなす引掛け部２５と、その外方に取り外し工具装着部２１を形成させ、引掛け部２５の径を取り外し工具装着部２１よりも細い鼓形状とし、セパレータ挿通工具の先方のらせん部を引掛け容易な構成にすると共に、取り外し工具装着部２１の少なくとも一部がコンクリート型枠の厚さの区域に位置するように構成した。【選択図】図３
