Abstract: A non-welded metal foundation includes a plurality of bodies formed of metal plates or metal sheets, each body being comprised of lateral ends with integrated planar fins, wherein each of the metal lateral ends overlap a lateral end of an adjacent body; a plurality of mechanical fasteners along each of the overlapped ends of adjacent bodies for mechanically fastening the bodies having the integrated planar fins; wherein said plurality of said bodies are configured for forming a closed perimeter of a geometrical shape having an open interior and wherein the integrated planar fins of each body extend away from the perimeter of the closed geometric shape along the plane of the fin.

Abstract: Disclosed are interlocking steel plate foundations of various configurations. Interlocking foundations eliminate the need for concrete foundations and have a much shorter assembly time. Interlocking foundations have fins which provide for increased torsional restriction for the same or less material than other metal foundations such as the metal fin tube style foundation.
