A locking collar that surrounds a hub of a space frame structure. Struts radiating from the hub pass through openings in the locking collar. The openings each have a size relative to a width of each of the struts that provides a locking action to the struts and limits movement of the struts, which gives support to a shape of the space frame. The locking collar provides support to beams of wood or other materials that are attached to the struts without placing stress on the hub. |
