PURPOSE:To provide a form block with a proper width, by a method wherein the flanges of an iron rod provided at both ends with the flanges are engaged with dove-tail grooves formed in concrete panel erected at a specified distance. CONSTITUTION:A pair of dove-tail grooves, extended in parallel to a short side, are formed in the one surface of a laminar concrete forming body 3. Meanwhile, a reinforcing rod 1 has a desired length, and is provided at its ends with flanges 2 respectively engaged with the dove-tail grooves 4 in the laminar concrete forming body 3. A pair of the concrete forming bodies 3, erected at a distance, receive the flanges 2 of the pair of the reinforcing rods 1 to form a form block with a specified width. This enables provision of the form block the width of which is freely set by varying the length of the reinforcing rod. |
