Abstract
Structural elements of great thickness are provided by having limited extent ribbing projecting from each surface structure coupled by junctions having extents which combined with the ribbing extents bridges the distance between the surface structures of the structural elements.

Structural element comprising first and second laterally and longitudinally extended surface structures spaced apart a predetermined distance, said surface structures defining respectively first and second opposed closed figure patterns of ribbing including rib segments extending vertically a combined distance less than said predetermined distance, and a laterally and longitudinally disposed series of junctions connecting said rib segments in predetermined distance bridging relation.
Structural element comprising first and second laterally and longitudinally extended surface structures spaced apart a predetermined distance, said surface structures defining respectively first and second opposed closed figure patterns of ribbing including rib segments comprising thin, elongated and vertically extended members having upper and lower edges in a common plane, said ribbing segment members extending vertically a combined distance less than said predetermined distance, and a laterally and longitudinally disposed series of junctions connecting said rib segments in predetermined distance bridging relation.
Structural element comprising first and second laterally and longitudinally extended surface structures spaced apart a predetermined distance, said surface structures defining respectively first and second opposed closed figure patterns of ribbing including rib segments extending vertically a combined distance less than said predetermined distance, and a laterally and longitudinally disposed series of junctions connecting said rib segments in predetermined distance bridging relation, said junctions comprising elongated sections adapted to cooperate with pairs of opposed ribbing segments in locking relation.
Structural element comprising first and second laterally and longitudinally extended surface structures spaced apart a predetermined distance, said surface structures defining respectively first and second opposed closed figure patterns of ribbing including rib segments extending vertically a combined distance less than said predetermined distance, a laterally and longitudinally disposed series of junctions connecting said rib segments in predetermined distance bridging relation, multiple ones of said ribbing segments projecting longitudinally from said junctions to a locus of intersection defining a corner of said closed figure pattern, and including also a joint at each said locus of ribbing segment intersection, said joints supporting said ribbing segments relative to each other between said junctions.
Structural element comprising first and second laterally and longitudinally extended surface structures spaced apart a predetermined distance, said surface structures defining respectively first and second opposed, generally rectangular, closed figure patterns of ribbing including rib segments extending vertically a combined distance less than said predetermined distance, and a laterally and longitudinally disposed series of junctions connecting said rib segments in predetermined distance bridging relation.
Structural element comprising first and second laterally and longitudinally extended generally parallel, planar surface structures of metal or fiber reinforced resin spaced apart a predetermined distance, said surface structures defining respectively first and second opposed, generally rectangular, closed figure patterns of ribbing including integrally formed with their respective said surface structures thin, elongated rib segment members having upper and lower edges in the same plane edgewise to said surface structures and extending vertically a combined distance less than said predetermined distance, and a laterally and longitudinally disposed series of junctions cooperating with said rib segment member edges to join opposed rib segment members in predetermined distance bridging relation, said junctions comprising elongated sections defining upwardly and downwardly opening grooves adapted to receive edgewise said segment members, said junction grooves being sized and spaced to extend in combination with said opposed ribbing segments received therein a distance equal to said predetermined distance;
- said ribbing segment members periodically defining a locus of intersection;
- and including also a joint at each said locus of ribbing segment member intersection, said joints each comprising a body having a plurality of upper and lower segment member receiving grooves at right angles to each other to receive opposed ribbing segment members laterally and longitudinally disposed with each locus of intersection in predetermined distance bridging relation, said joints supporting said ribbing segment members relative to each other between said junctions.
