Abstract: A supporting framework with connection node and struts has at least two strut receiving elements, each strut receiving element being arranged centrally on an imaginary cube face of the connection node. Arms extend from the strut receiving elements and run parallel to the edges of the imaginary cube face and extend up to an edge of the imaginary cube face that is perpendicular to the arms. The arms of one strut receiving element meet arms of an adjacent strut receiving element arranged orthogonal thereto and form at least one loop. A connection element can be hooked into the loop for producing a diagonal connection.
