Abstract
Disclosed is a connector system for structural frameworks which comprises a strut element (14) having one end connected to the end of a beam member (16). The strut element (14) has an axial bore (26) with the head portion of a bolt (36) retained therein. The shank (40) of the bolt extends outwardly from the strut element for threaded engagement with a correspondingly threaded aperture of a dodecahedral node (12). A drive nut (42) is fixed to the shank of the bolt and used for rotating the bolt so that the shank is screwed into the node (12). A set screw (46) passes through the strut element (14) to impinge upon the head of the bolt thereby preventing rotation of the strut element with respect to the bolt. A hollow metal rod (54) extends through the end of the beam member (16) and aligned apertures (52) in the end of strut element (14). The ends of the rod are riveted to secure the strut element to the beam member.
