An exemplary axial joint includes a planar member having a first plurality of joined sections and a second plurality of joined sections perpendicular to the first plurality of joined sections. Each section of the first plurality of joined sections and the second plurality of joined sections has a pattern of apertures therein, and each section is foldable approximately perpendicular to an adjacent section. The pattern of apertures in a first section after folding is congruent with the pattern of apertures in a second section after folding, wherein the second section is parallel to the first section, after folding. An elongate member is arranged through the apertures of one or more sections of the planar member, after folding the sections of the planar member.

The invention relates to the field of building, and more particularly to a space frame, and can be used for creating wall structures, columns, supports, ceilings and complex dome structures for different purposes. The space frame comprises rods and polyhedral nodes with threaded apertures on the faces thereof for fastening said rods, wherein the rods have a tubular cylindrical shape and have an external thread on their ends, the diameter of the external thread of a rod corresponding to the diameter of a threaded aperture, and the space frame further comprises a coupling with an internal thread, capable of detachably connecting rods. The technical result is that of simplifying and expediting assembly by standardizing the component parts, while at the same time preserving the strength of the space frame.
