<p>A space truss system comprising at least two planar grids (106, 102), the grids (106, 102) being substantially parallel and adjacent grids (106, 102) being connected by at least one diagonal strut (116). The grids (106, 102) are connected at the intersection of their respective cross members (nodes) (112, 114) and each connection is secured by a single connector (120) which is passed through a hole in the node (112, 114) (not shown), the hole being substantially perpendicular to the plane of the grid (106, 102). The diagonal strut (116) is connected to the connector (120) by means of a connecting section on the strut (116) formed by part of the strut (116), the connecting section being shaped and angled to be parallel to the planar grid (102, 106) whilst the diagonal strut (116) is connected to the planar grid (102, 106). In one embodiment, the strut (116) has a connecting section formed at each end. In an alternative embodiment, the strut (116) is V-shaped and has a connection section being formed at its centre by flattening portions of the tubular members.</p> |
