ABSTRACT:
A concrete column form structured to receive concrete therein for hardening into a building column having a curvilinear exterior surface. The form includes at least two form portions having a flat, thin generally rectangular sheet of resilient material and an elongated, rigid, straight edge bar connected along opposing side margins of each sheet. Each sheet is flexible by manipulation into a curvilinear configuration along its length by opposing rotation and inward movement of each of its connected edge bars. Connected together in side-by-side fashion along adjacent edge bars, the plurality of curvilinear-configured form portions complete the form itself. Both cylindrical and tapered building columns may be easily fabricated either in place or in a factory utilizing this invention.
