Abstract
A lightweight permanent concrete footing form section includes a base sheet that is horizontal with substantially planar upper and lower surfaces. Side walls integral with the base append upward from the base in a generally vertical and planar direction. Ducts are attached to the side walls for carrying water away from the concrete footing after the concrete has been poured and set. Sections may be interconnected and dimensioned according to plans.
Claims16
A footing form section comprising:
- a. a base sheet including substantially planar first and second surfaces, the base sheet further including a first edge, a second edge and two side edges;
- b. two substantially planar side walls, the side walls being integral with the base sheet and appending at an angle from the side edges, wherein each side wall includes a first surface integral with the first surface of the base sheet and a second surface integral with the second surface of the base sheet, the side walls further having a first side wall edge integral with the base sheet and an opposing second side wall edge;
- c. a duct integral with the second surface of each side wall for directing ground fluid
- d. a first lip integral with the first edge and a second lip integral with the second edge, wherein each of the first and second lips extend downward below the base sheet;
- and
- e. a coupler including a channel for receiving therein the first lip from one footing form section and the second lip from another footing form section.

A footing form section comprising:
- a. a base sheet including substantially planar first and second surfaces, the base sheet further including a first edge, a second edge and two side edges, and additionally a ridge integrally attached to the second surface and extending from the first edge to the second edge in a direction parallel to the side edges;
- b. two substantially planar side walls each respectively integrally attached to the side edges and appending at an angle therefrom, each side wall including a first surface integral with the first surface of the base sheet and a second surface integral with the second surface of the base sheet, with the first and second surfaces of the side walls each including a pocket thereupon, and each side wall further including a first side wall edge integral with the base sheet, and an opposing second side wall edge;
- c. a beam having two ends, the beam spanning from side wall to side wall with each end retained within a pocket;
- d. a rectangular duct integral with the second side wall edge and positioned on the second surface of each side wall;
- e. a first lip integral with the first edge and a second lip integral with the second edge, wherein each of the first and second lips extend downward below the base sheet;
- f. a coupler including a channel for receiving therein a first lip from one footing form section and a second lip from another footing form section, the channel having a length extending substantially from side edge to side edge;
- and
- e. an aperture extending through the base sheet from the first surface to the second surface, wherein a spike may be inserted and disposed into material adjacent the second surface to anchor the footing form section from movement.
