Concrete column form

A concrete column form including a plurality of self-aligning, half-round sections secured together by a plurality of bolts, each said section comprising:

• a semi-cylindrical wall having a top edge, a bottom edge and opposite side edges;
• a semi-circular top flange connected to and extending radially outwardly from said top edge, including a semi-circular raised ridge and a radially extending raised ridge extending upwardly therefrom and a plurality of apertures therethrough;
• a semi-circular bottom flange connected to and extending radially outwardly from said bottom edge and including a semicircular indented notch and a radially extending indented notch opening downwardly therefrom for receiving the raised ridges from the top flange of a subjacent section for aligning the same and a plurality of apertures therethrough circumferentially aligned with said top flange apertures for receiving said bolts to fasten the same to the top flange of said subjacent section;
• and
• a pair of side flanges each connected to and extending radially outwardly from a respective one of said side edges between said top flange and said bottom flange, each said side flange including a plurality of aligned apertures therethrough for receiving said bolts to fasten the same to one side flange of an adjacent section to form a cylindrical column form.
