ABSTRACT:
A support structure having any number of sides from three to round that includes a lattice structure formed from a flat plate assemblage of components preferably constructed by appropriately cutting slots at intervals in a flat plate so as to form corner and intermediate gusset plates with connected braces, which braces are then each preferably bent along their longitudinally axis into angle braces, the groups of corner and intermediate gusset plates and braces making up sections or tiers of the lattice structure, the tiers nesting alongside on another, such that, when the structure is erected by lifting or elevating the center thereof, the angle braces bent at their joints with the gusset plates telescoping the assemblage into a three dimensional longitudinally tapered structure. The structure is then supported at corners of each tier between vertical legs that connect at intervals to the corner gusset plates of each tier of the tapered structure. Alternatively, the joints between the gusset plates and braces can be upset for a permanent structure or can be hinge couplings where the structure is intended to be later collapsed back to its original flat state for movement and subsequent reassembly.
Additionally, a practice of the present invention can include forming a truss lattice structure by also slotting a rectangular flat plate to form interconnected gusset plates and braces, which braces are then cold formed into angle braces, and the truss lattice structure is erected by pulling apart the opposite rectangular plate ends, the braces bending at their upset joints to the gusset plates, with supports then secured at intervals to outside or edge gusset plates to form a truss.
