Abstract
The present invention relates to a decorative remaining formwork formed by combining a plurality of single frame plates defined by 3 or more edges comprising one edge arranged horizontally and at least one inclined edge inclined with respect to the horizontal edge; arranging the single frame plates so as to form a predetermined gap in a joint-shape between respective edges of the single frame plates adjacent each other; and having a back plate on a concrete casting surface, the back plate covering the predetermined gap in a longitudinal direction, and being fixed to the single frame plate to connect the single frame plates adjacent each other, and a cross-sectional shape in a width direction of the back plate being formed into a shape enlarged from a contact surface with respect to the single frame plate toward an opposed surface with respect to the contact surface.
