ABSTRACT:
A reusable column mold particularly adapted for use in casting concrete pillars or columns, that mold including a sheet of flat, flexible material which can be rolled into a columnar configuration to erect the mold form and which can be readily stripped from a set-up concrete column cast into the mold form. In preferred form, the flat sheet is of a rectangular configuration and is characterized by a plurality of tongues on one side edge which, when the sheet is rolled into columnar configuration, are adapted to fit into slots in the sheet located on one of a series of slot lines (the slot lines are parallel to the sheet's tongued side edge and are positioned intermediate the sheet's side edges); the cross-sectional area of the mold form is determined by that slot line of the sheet which cooperates with the sheet's tongued edge. The mold form is retained in set-up configuration by banding at spaced locations along its length, the banding serving to force the tongues fully into the slots, to prevent the form from unwrapping out of columnar configuration, and to reinforce the flexible material in columnar configuration. Further, visual indicia is provided on the sheet, and is adapted to cooperate with a port in the sheet when it is rolled into columnar configuration, to indicate the cross-sectional area of the erected mold form.
