Adjustable modular form system and method for rectilinear concrete column form

A system for constructing a concrete column form, the system comprising:

• a plurality of form panels, each of the form panels having a first side edge, a second side edge, a top edge, a bottom edge, and a generally planar skin, the first side edge of each of the panels including a widened edge member extending entirely rearwardly of the skin, a portion of the edge member forming an abutting surface adapted for abutting contact with the skin of art adjacent panel, each of the form panels further including:
• first and second vertically oriented gage lines defined on the first side edge, the first and second gage lines of the first side edge spaced apart a first distance, each of the gage lines of the first side edge including a plurality of attachment holes, each of the attachment holes in the first gage line of the first side edge and a corresponding attachment hole in the second gage line of the first side edge spaced equidistantly from the top edge;
• and
• a plurality of vertically oriented gage lines defined on the skin and spaced apart a second distance greater than the first distance, each of the gage lines of the skin including a plurality of attachment holes, each of the attachment holes in each of the gage lines of the skin aligned with a corresponding attachment hole in an adjacent gage line of the skin, each attachment hole of the skin and its corresponding attachment hole of the skin spaced equidistantly from the top edge;
• and
• wherein the attachment holes of the first and second gage lines of the first side edge of each panel are disposed and spaced on the first side edge so as to permit registration with and attachment to the attachment holes of any one of the gage lines on the skin on an adjacent panel when the top edges of the adjacent panels are horizontally aligned.

A form system for use in constructing a concrete column form, the form system comprising:

• four panels, each panel including:
• a top edge;
• a bottom edge;
• a first side edge, the first side edge including only a pair of gage lines, the pair of gage lines including first and second vertically oriented gage lines, each of the gage lines including a plurality of round holes, each of the round holes in the first gage line horizontally aligned with an adjacent round hole in the second gage line;
• a second side edge;
• and
• a generally planar skin, the skin including a plurality of vertically oriented gage lines, each of the gage lines of the skin including a plurality of round holes, each hole in each of the gage lines horizontally aligned with an adjacent hole in a next adjacent gage line;
• the first side edge of each of the panels including widened edge member extending entirely rearwardly of the skin, a portion of the edge member forming an abutting surface adapted for abutting contact with the skin of an adjacent panel;
• and
• wherein the attachment holes of the first and second gage lines of the first side edge of each panel are disposed to permit registration with and attachment to the attachment holes of any one of the gage lines on the skin of an adjacent panel when the top edges of the panel and the adjacent panel are aligned.

A method of constructing a concrete column form having a desired one of a plurality of available cross-sectional dimensions, the method comprising the steps of:

• choosing the desired cross-sectional dimension to be constructed;
• providing a plurality of form panels, each of the form panels having first and second side edges, top and bottom edges, and a generally planar interconnecting skin, the first side edge of each of the panels including a widened edge member extending entirely rearwardly of the skin, a portion of the edge member forming an abutting surface adapted for abutting contact with the skin of an adjacent panel;
• providing the first side edge of each of the panels with a plurality of attachment holes arranged in a plurality of vertically oriented gage lines, each of the attachment holes in a first one of the plurality of gage lines horizontally aligned with an adjacent attachment hole in an adjacent and second one of the plurality of gage lines;
• providing the skin of each of the panels with a plurality of attachment holes arranged in a plurality of vertically oriented gage lines, each of the attachment holes in the skin horizontally aligned with an adjacent attachment hole in an adjacent gage line;
• aligning the top edge and the bottom edge of each of the panels with the top edge and the bottom edge of an adjacent panel;
• and
• securing the attachment holes from a selected one of the gage lines on the first side edge of each panel to the attachment holes from a selected one of the first and second gage lines on the skin of an adjacent panel.
