<p>The invention concerns a method for making a tubular trellised structure (5) comprising chord members (3) interconnected by spacers (4), for making a building framework and in particular a truss (1, 6). The invention is characterized in that the spacers are produced continuously from a slender profiled section (14) which has been folded at several points, and forming a trellis, each of the successive folded parts producing a new spacer with specific length and orientation, adapted in dimension and orientation to its position in the geometry of the structure.</p> |
