Abstract: A space frame has nodes which are made up of juxtaposed plates with the ends of the frame chords sandwiched between them. The chord ends are equipped with collars that have projecting diametrically opposed nibs that fit into corresponding apertures in the plates. The collars may be cruciform in shape, with shoulders between the nibs against which the plates bear to prevent direct clamping of the chords. A second pair of plates to receive the ends of diagonal chords may be bolted to the first pair by a single bolt passed through registering central holes in the plates.

Abstract: Coupling means for use in erecting a framework structure, which includes a node having on its outer surface a plurality of primary faces disposed in a predetermined arrangement and secondary faces associated with the primary faces, each secondary face being arranged to occupy the same position relative to a primary face as other secondary faces occupy relative to their associated primary faces; and at least one retaining member having holding means for holding it on a primary face of the node, the retaining member having at least one ear locatable on a secondary face associated with the primary face on which the retaining member is locatable, the ear having a locating formation to permit location of the end of a cross member or a connector for a cross member in a load supporting position against a secondary face of the node.
