Title (EN) STRUCTURAL ELEMENT,TETRAHEDRAL TRUSS CONSTRUCTED THEREFROM AND METHOD OF CONSTRUCTION
(FR) ELEMENT DE STRUCTURE, ARMATURE TETRAEDRIQUE CONSTRUITE A PARTIR DE CELUI-CI ET PROCEDE DE CONSTRUCTION
Abstract: front page image
(EN)A three-dimensional, tetrahedral truss and its method of construction are provided. The truss comprises a three-dimensionally periodic skeletal array of an interconnected plurality of skeletal-tetrahedric units, the array being in the pattern of the cubic-diamond crystallographic structure (FIG. 7). In one embodiment, each of the skeletal-tetrahedric units is an articulated arrangement of struts (44) joined in the pattern of an equilateral skeletal-tetrahedron (FIG. 4). In another, more preferred embodiment, each of the skeletal-tetrahedric units is a skeletal arrangement of elongate members (80) joined in the pattern formed by the face members of a cubic-diamond unit-cell (FIG. 10), and is preferably assembled from four hexagonic triplanar-rings (FIG. 10A) being of the form created by joining six bilateral-elements (80) in a closed ring, triplanar pattern (FIG. 9), the bilateral-elements (80) each having equal sides and having an included angle of about 109 28" (FIG.8).
(FR)Une armature tridimensionnelle, tetraedrique et son procede de construction. L"armature comprend un motif d"ossature periodique tridimensionnelle d"une pluralite d"unites tetraedriques reliees entre elles, l"ossature ayant la forme ne structure cristallographique cubique du type diamant (Fig. 7). Dans un mode de realisation, chacune des unites tetraedriques d"ossature est un dispositif articule d"entretoises (44) assemblees sous forme d"un tetraedre d"ossature equilaterale (Fig. 4). Dans un autre mode preferentiel de realisation, chacune des unites tetraedriques d"ossature est un dispositif d"ossature compose d"organes allonges (80) assembles suivant la configuration formee par les faces d"une cellule unitaire d"un diamant cubique (Fig. 6), et chacune d"elles est assemblee, de preference, avec quatre anneaux hexagonaux triplanaires (Fig. 10A) ayant la forme produite en joignant six elements bilateraux (80) dans un anneau ferme, de configuration triplanaire (Fig. 9), les elements bilateraux (80) ayant chacun des cotes egaux et un angle interieur d"environ 109 28" (Fig. 8).
