Abstract
A framework structure defined by a first plurality of tetrahedral elements laterally juxtaposed in a first array and a second plurality of tetrahedral elements laterally juxtaposed in a second array, with the projecting apices of the first array received in the spaces between the projections of the second array and the projecting apices of the second array received in the spaces between the projections of the first array. In the illustrated embodiment, the bases of the tetrahedral elements of the first array define a common plane and the bases of the tetrahedral elements of the second array define a common plane extending parallel to the plane of the first array bases. The tetrahedral elements in the illustrated embodiment are formed of edge elements and corner connectors. The corner connectors are secured in interconnected association and, in the illustrated embodiment, the corner connectors are secured by connecting plates. The apices of the complementary array are also secured to the connecting plates to secure the two arrays in assembled association in the illustrated embodiment. The edge elements may be fixedly secured to the corner connectors. The connections between the tetrahedral elements are preferably removable so as to permit ready assembly and disassembly of the desired arrays, such as for use in forming a platform deck in a derrick construction or the like.
