ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATIONS

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not Applicable.
BACKGROUND OF THE INVENTION
This invention relates to concrete column forms, and in particular, to a paperboard form or mold which enables a recessed ring to be easily formed in a poured concrete column.
Buildings often include concrete columns as architectural accents. To make the columns more aesthetically pleasing, various accents are added to the concrete columns. For example, columns have been made which have recessed rings or circumferential grooves. Columns with such rings or grooves are very time consuming and expensive to make. Further, the results are not consistent. Currently, such a column would be created by building a form (which defines the ring or groove) on site, and then pouring cement into the form so built. The construction of such forms is time consuming and expensive.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, a mold is provided for forming a concrete column having at least one recess formed therein, as molded. The mold includes a tubular housing having an inner surface and a recess form having an inner and an outer surface. The housing can be formed from a spirally wound paperboard tubes. The recess form is mountable in the housing at a desired location on the inner surface of the mold housing. The recess form is preferably generally a ring. The ring's outer surface corresponds to the shape of the housing's inner surface so that, when the ring is mounted in the housing, there are substantially no gaps between the outer surface of the ring and the inner surface of the housing. The ring has a slice through it, so that the ring may be expanded and pried out of the groove or recess molded in the column once the cement has set. Preferably, the slice is off-set from a radial line drawn through the ring. The ring is secured in place in the mold using screws. Preferably, the housing and ring are made of fiberboard though which the fasteners can be driven without the need for pre-drilled holes.
