US 6,314,693 B1 · Building foundation using pre-cast concrete elements

Abstract

A building foundation is formed by a plurality of pre-cast concrete elements. Each of the pre-cast elements has a length corresponding to the length of a corresponding side or leg of the foundation perimeter. The foundation includes a plurality of pre-cast concrete footing pads that are dispersed along the perimeter and specifically at the corners of the foundation. The pre-cast foundation elements rest on the footing pads and are contiguously arranged to complete the foundation. A bonding agent can be introduced into the joints between adjacent foundation elements to seal the joint. Alternatively, or in addition, mechanical fasteners can be used to interconnect adjacent panels. Certain ones of the pre-cast foundation elements define an integral brick ledge, with varying configurations to ensure continuity of the brick ledge around the corners of the foundation. In a method of the invention, a trench around the perimeter is dug and the pre-cast concrete elements laid in place with a crane.

Dependent claims

A foundation for a building in which the foundation occupies a perimeter defined by a plurality of contiguous sides, each of the sides having a length along the perimeter, and in which the foundation is buried in a trench along the perimeter at a depth below the frost line, said foundation comprising:

a plurality of pre-cast panels, one each for each of the plurality of contiguous sides and each having a length approximately equal to the length of the corresponding contiguous side, each of said pre-cast panels having substantially equal widths and heights from a base to a top side thereof;
and
a plurality of footing pads each having a width greater than the width of said pre-cast panels, a length substantially less than the length of said pre-cast panels, and a height that is substantially less than the height of said pre-cast panels,
wherein a combined height of one of said plurality of pre-cast panels and one of said plurality of footing pads is substantially equal to the depth of the foundation trench such that said top side of said plurality of pre-cast panels is situated adjacent ground level when said panels are mounted on corresponding ones of said footing pads within the foundation trench, and
further wherein said plurality of pre-cast panels are disposed in contiguous arrangement around the foundation perimeter.
