<p>A double-layer space frame (50) having spaced major surfaces including substantially orthogonally disposed longitudinal and transverse structural chord framing members (51, 52, 53, 54, 55, 57) defining the frame major surfaces and structural strut framing members (60) in diagonal planes oblique to the frame major surfaces and spacing the major surfaces from each other, and in which chord members and strut members are interconnected at spaced apart nodes in the frame (50) so that strut members connected to a node in one surface of the frame are connected to respectively different nodes in the other surface of the frame, the frame including at each node in the frame a node connector (69) comprising an elongate body defining an open-ended circumferentially closed passage extending along the length of the body which is configured and sized to enable a longitudinal chord member to extend continuously through the body and plural strut and lateral chord member connection surfaces extending laterally from the body substantially parallel to respective planes which intersect substantially in a line extending centrally of the passage, the connection surfaces enabling struts and lateral chord members substantially disposed in respective ones of the planes to be connected to the node connector.</p> |
