<p>A space frame comprises an upper rectangular grid of horizontal structural members (21B to 24B) and a corresponding lower grid of horizontal structural members (21A to 24A). Upper and lower grids are interconnected by upright members (25A, 25B) at intersections. The structure is built up from prefabricated modules (A, B, etc.) each of which comprises one upright member and four orthogonally arranged horizontal members (21 to 24). Alternate modules (B) are inverted and the outer ends of horizontal members (21A, 21B) are fixed to the free ends (31B, 31A) of the upright members (25).</p> |
