1. A collapsible, multi-lap foundation assembly, comprising:
four shaped perimeter rails; a plurality of rib elements, wherein each rib element comprises an elongate, central rib portion having a rib tab element formed at each end of the central rib portion, wherein the rib tab elements are able to flex, via a rib hinge portion, relative to the central rib portion, and wherein a plurality of half-lap rib joints extend from an upper portion of the central rib portion at spaced apart locations; and a plurality of spine elements, wherein each spine element comprises an elongate, central spine portion having a spine tab element formed at each end of the central spine portion, wherein the spine tab elements are able to flex, via a spine hinge portion, relative to the central spine portion, and wherein a plurality of half-lap spine joints extend from a lower portion of the central spine portion at spaced apart locations; wherein the spine elements are aligned with the rib elements in an interlocking fashion via interaction of mating half-lap rib joints and half-lap spine joints, such that the spine elements are pivotable relative to the rib elements via interaction of mating half-lap rib joints and half-lap spine joints; and wherein the rib tab elements are attached or coupled to an interior surface of two perimeter rails at spaced apart locations, and wherein the spine tab elements are attached or coupled to an interior surface of two perimeter rails at spaced apart locations. |
