<p>A molding flask (10) for building concrete structures is made of thermoplastic resin containing inorganic material, and comprises a first main plate (11) facing cast concrete, a second main plate (12) opposed to the first main plate, and partition plates (15, 16) disposed between the first and second main plates. The partition plate (15) is formed with a number of first reinforcing sections (30) disposed in a left-right widthwise direction and having at least one type of cross-sectional shape selected from substantially rectangular shapes and substantially truss shapes. Further, in a place (52) where columnar reinforcing bodies (40) for supporting the molding flask are nailed down, the partition plate (16) is formed with a second reinforcing section (31) having a substantially rectangular cross-sectional shape with a width capable of supporting the outer edge of the head (51) of a nail (50).</p> |
