ABSTRACT:
This invention relates to a connector for the elongated elements of a structural space frame, and to a space frame employing the connectors. The connector consists of a base element and up to two elongate connector members. The base element includes both first and second bores lying along first and second axes, and first and second pairs of parallel faces intersecting with the first and second axes respectively at right-angles. The first and second elongate connector members are housed within the first and second bores of the base element, and each connector member includes outwardly extending threaded portions at both ends, the threaded portions being parallel screw threads. The threaded portions respectively engage adjacent primary elongated frame elements, by means of tightening these elements in opposite axial directions against the base element. The first and second axes are arranged in substantially parallel planes, spaced apart by substantially the diameter of a single elongate connector member. The connector base element also comprises apparatus for supporting a plurality of diagonal frame elements lying along axes intersecting at the connector with the substantially parallel planes.
