FORMWORK FOR DETERMINING CONCRETE DEMOLDING STRENGTH
To provide a formwork for determining concrete demolding strength that improves determination accuracy of a demolding time and can be used repeatedly while leaving no mold to be buried on a concrete side at the time of demolding the concrete.SOLUTION: With a formwork for determining demolding strength, specific resistance is obtained by measuring a potential difference between electrodes 4, 4 in a state in which the plurality of electrodes 4, 4 are brought into contact with concrete placed in a framework, and strength at the time of demolding is determined from the specific resistance. The formwork for determining demolding strength includes a resin plate 2 that also serves as the framework, and a sheet 5 with an electrode in which a plurality of, at least four or more, flexible thin electrodes 4, 4. are arranged side by side at one surface side of an insulating sheet 3 at an interval in a certain direction. The other surface side of the sheet 5 with the electrode is adhered and attached relative to the resin plate 2 in an area A avoiding a section corresponding to the electrodes 4, 4.SELECTED DRAWING: Figure 5
【課題】脱型時期判定精度の向上を図るとともに、コンクリートの脱型時にコンクリート側に埋め殺しになるものを残さず、繰り返して使用できるようにするコンクリートの脱型時強度判定用型枠を提供する。【解決手段】型枠内に打設されたコンクリートに複数の電極４，４…を接触させた状態で前記電極４，４間の電位差を計測することによって比抵抗を求め、この比抵抗から脱型時の強度を判定する脱型時強度判定用型枠である。脱型時強度判定用型枠は、型枠を兼ねる樹脂板２と、絶縁性シート３の一方面側に一定方向に間隔を空けて、可撓性を有し薄肉の電極４，４…が少なくとも４本以上複数並設された電極付きシート５とからなり、前記電極付きシート５の他方面側を前記樹脂板２に対して、前記電極４，４…に対応する部分を避けた領域Ａにおいて接着し取り付けてある。【選択図】図５
