To provide a form panel connector capable of assembling a wooden form by utilizing a conventional wooden form panel as it is, enabling even a worker accustomed to a conventional fastening method to perform work without confusion, and preventing the wooden form panel from being stuck to a sash bar even when screwing work is performed by using a power tool.SOLUTION: In a form panel connector used for assembling a form for fastening a plurality of form panels 4 and placing concrete, the form panel connector comprises a screw part 1, a head part 2 having a regular hexagonal prism shape at its upper part, and a washer part 3, wherein the washer part 3 covers the whole lower surface of the head part 2 and has an extension part extending around the lower surface side of the head part 2, and the extension part is bent in the upper surface direction of the head part 2 and bites into the opposite surface of the head part 2.SELECTED DRAWING: Figure 5
【課題】従来の木製型枠パネルをそのまま利用して木製型枠を組みあげることができ、従来の締結方法に慣れている作業員もとまどうことなく作業でき、電動工具を使用してねじ込み作業を行っても桟木にめりこまない型枠パネル連結具を提供する。【解決手段】複数の型枠パネル４を締結してコンクリートを打設するための型枠を組みあげる際に用いる型枠パネル連結具であって、ネジ部１、上部が正六角柱状の頭部２及びワッシャー部３からなり、ワッシャー部３は頭部２の下面全面を覆うとともに頭部２の下面側の周囲に延出する延出部を有し、延出部は頭部２の上面方向に曲折しているとともに頭部２の対向する面に食い込んでいる型枠パネル連結具。【選択図】図５
