Interlocking Steel Plate Foundation

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. Optionally multiple foundations can also be linked together to construct foundations of any shape and size

1 . An interlocking foundation comprising:
 a bottom plate with an upward slot and a top plate with a downward slot;   whereby the upward slot and the downward slot are used to interlock the bottom plate and the top plate to form an interlocking foundation.   
     
     
         2 . The interlocking foundation of  claim 1 , further comprising a top mounting plate, the top mounting plate comprising a flat plate and a plurality of side overhangs. 
     
     
         3 . The interlocking foundation of  claim 1 , wherein the upward slot and the downward slot are centered within their respective plates. 
     
     
         4 . The interlocking foundation of  claim 1 , wherein the bottom plate and the top plate are identical in size and shape. 
     
     
         5 . An interlocking pipe support foundation comprising:
 a bottom plate with a central upward slot and two upward pipe slots on the same side of the bottom plate; each upward pipe slot being equidistant from the central upward slot;   a top plate with a central downward slot and two upward pipe slots; the central downward slot and two upward slots being on opposite sides of the top plate; each upward pipe slot being equidistant from the central downward slot;   whereby the central upward slot and the central downward slot are used to interlock the bottom plate and the top plate to form a base foundation;   a pipe with downward receiving slots that align with the upward pipe slots of the base foundation;   whereby the upward pipe slots and the downward receiving slots interlock to form an interlocking pipe support foundation.   
     
     
         6 . An interlocking angle foundation comprising:
 a bottom plate comprised of two legs connected at an angle to one another, each leg comprised of an angled leg flange, and each leg comprised of an upward slot;   a top plate comprised of two legs connected at an angle to one another, each leg comprised of an angled leg flange and each leg comprised of a downward slot;   whereby the upwards slots and the downward slots are used to interlock the bottom plate and the top plate to form an interlocking angle foundation comprised of a central tube and four bent fins.   
     
     
         7 . The interlocking angle foundation of  claim 6  wherein the two legs are connected to one another at a 90 degree angle. 
     
     
         8 . The interlocking angle foundation of  claim 6  wherein each angled leg flange is angled at 90) degrees to its respective leg. 
     
     
         9 . The interlocking angle foundation of  claim 6 , further comprising a top mounting plate, the top mounting plate comprising a flat plate and a plurality of side overhangs. 
     
     
         10 . The interlocking angle foundation of  claim 6 , wherein the bottom plate and the top plate are identical in size and shape.
