Abstract:
A space frame (10) comprising upper and lower grids (12, 14) of intersecting chords (16, 18), bracing modules (30) interconnecting the upper and lower grids (12, 14) in Spaced apart relationship, the bracing modules (30) being spaced apart from one another in each grid direction, wherein the bracing modules (30) comprise four intersecting bracing member (32), the bracing members (32) arranged in mutually inclined pairs, the bracing members (32) of each pair extending between upper and lower chords (16, 18) in the same grid direction, each pair of bracing members (32) crossing the other pair of bracing members (32), the point of crossing (34) of each pair of bracing members (32) coinciding with or being positioned between each member of the other pair of bracing members (32) and either the upper or lower chord (16, 18) associated with the other pair of bracing members (32), the bracing members (32) of one bracing module (30) being spaced apart longitudinally of the chords (16, 18), from bracing members (32) of adjacent bracing modules (30), at their points of interconnection with the chords (16, 18).
