Abstract
A foundation unit having a top bearing grid structure secured to a bottom substructure by intermediate support elements. The grid structure comprises a series of spaced longitudinal and transverse spring elements, each spring element being formed to permit elastic elongation thereof. Elastic elongation is accomplished by a series of V-shaped segments in each of the spring elements, the segments being located at the intersections of the spring elements and being joined by a clip. The support elements comprise wire elements which are L-shaped and which are composed of two planar portions connected at right angles to one another. The wire elements are located in transverse rows with the orientation of the wire elements in each row being opposite to the orientation of the wire elements in the adjacent row so that loads applied to the foundation unit are balanced.
