ABSTRACT:
A connector hub made in a single integrally cast unit for connecting the ends of the stringer frame members of a geodesic dome structure, said hub being characterized by a plurality of pairs of spaced apart flange elements defining stringer receiving slots arranged in generally radially extending relation around the central axis of the hub unit with stiffening web elements disposed between adjacent slots, to provide an extremely strong and rigid connector hub for the stringers which is also specifically designed to abut the ends of the stringer elements to provide additional rigidity for the stringer connection.
