To provide a technology in which generation of a defective portion GP can be avoided and a formwork holder is not exposed on a concrete surface, to solve a problem in prior art.SOLUTION: A formwork holder of this invention is connected to a separator and holds a formwork for installing concrete, and comprises a shaft leg material and a connection material. The shaft leg material is a member including: a shaft leg comprising a first shaft leg portion and a second shaft leg portion; and a plate-shaped formwork holding plate provided in a boundary between the first shaft leg portion and the second shaft leg portion. On the other hand, the connection material is a member including a hollow cylindrical body comprising a first cylindrical portion and a second cylindrical portion. When a first male screw is screwed with a second female screw, a gap portion is formed between a tip end face of the second cylindrical portion and the formwork holding plate.SELECTED DRAWING: Figure 2
【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち欠損部ＧＰの発生を回避することができ、しかも型枠保持具がコンクリート表面に露出しない技術を提供することである。【解決手段】本願発明の型枠保持具は、セパレータに連結され、コンクリート打ち込み用の型枠を保持する型枠保持具であって、軸足材と連結材を備えたものである。このうち軸足材は、第１軸足部及び第２軸足部からなる軸足と、この第１軸足部と第２軸足部との境界に設けられる板状の型枠支持板を有する部材である。一方の連結材は、第１筒状部及び第２筒状部からなる中空の筒状体を有する部材である第１雄ねじと第２雌ねじが螺合すると、第２筒状部の先端面と型枠支持板との間に間隙部が形成される。【選択図】図２
