A space frame structural system capable of varying curvature wherein the ends (50) of elongated frame members have fixedly attached headed ends (23) which, in turn, fit into matching recesses (31) in the connector joint. The connector comprises three, disk-like parts (20, 30, 40) which nestle one on top of another on a common axis and which are held together with a single bolt (32). Each of three connector parts (20, 30, 40) share interior faces with another part and have matching recesses (22, 29, 31) for joining the frame member ends (50). A minimum of two frame member ends (36) have an improved T-shape which strengthens the connector under tensile forces, enchances the alignment of the framework during assembly, and helps the space frame resist racking after erection. An intermediate assembly nut (35) and an improved location for its placement is provided in the interior of the connector, the use of which, significantly simplifies the assembly process into fewer, more manageable stages. |
