ABSTRACT:
A joint connector for a space frame comprises two pairs of opposed brackets having seats for the transverse chords of the grid. Upon securing the brackets one to the other a housing encompasses the intersection of the transverse chords therein. An aperture chord mounting flange extends from each corner and towards the opposing grid of the space frame. Each diagonal chord extending between the upper and lower grids has an aperture mounting plate welded thereto. Upon alignment of apertures between the mounting plate and chord mounting flange, bolt
ut combinations secure one to the other. An alternative embodiment presents a brake/spacer plate to preclude the diagonal chord from being positioned away from a desired extension away from the joint connector. The joint connectors allow the transverse and diagonal chords of the space frame to be secured off-site and/or in a ground-adjacent position which reduces the fabrication assembly and erection costs.
