ABSTRACT:
A concrete form comprises a single insert assembly or a plurality of insert assemblies within an outer tube. Each insert assembly comprises a pre-formed polymer liner sheet, a pre-formed polymer backing sheet, and a plurality of prefabricated cellular material pieces. Each cellular material piece has a first surface configured to form a portion of the non-round cross-section desired for the column and an opposite second surface formed substantially as an angular section of a cylinder. An insert assembly is constructed by affixing the liner sheet to the first surfaces of a plurality of the cellular material pieces. The cellular material pieces are arranged in a plurality of laterally adjacent rows extending lengthwise along the liner sheet for a length approximately equal to the length of the outer tube. The backing sheet is then fixed to the second surfaces of the cellular material pieces. The liner sheet and backing sheet together substantially fully envelope the cellular material pieces.
