Supporting Framework Comprising Connection Nodes and Struts, Connection Nodes, Connection Element for Producing a Diagonal Connection between a Connection Node and Struts of a Supporting Framework, and Connection Element for Producing a Holding Device for a Flat Element

Supporting framework comprising:

• a connection node having at least two strut receiving elements, each strut receiving element being arranged centrally on an imaginary cube face of the connection node;
• and
• a plurality of arms extending from each of the strut receiving elements, the arms disposed generally parallel to the edges of the imaginary cube face and extending up to an edge of the imaginary cube face that is perpendicular to the arms, the arms of one strut receiving element meet the arms of an adjacent strut receiving element arranged orthogonal thereto and form at least one loop;
• whereby a connection element is hooked into the loop for producing a diagonal connection.

A connection node for press-fit connection of struts of a supporting framework, the connection node comprising:

• at least two strut receiving elements, each strut receiving element being arranged centrally on an imaginary cube face of the connection node;
• whereby arms extend from the strut receiving elements and run parallel to the imaginary cube faces and extend up to an edge of the imaginary cube face;
• and
• whereby 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 for producing a diagonal connection between a connection node and struts of a supporting framework, the connection node comprising:

• at least one hook element,
• at least one tensioning sleeve;
• and
• at least one fixing element.

A connection element for producing a holding device for a flat element, the connection element comprising:

• at least one hook element;
• and
• a first disk-shaped element;
• and a second disk-shaped element;
• wherein the first and second disk-shaped elements cooperate to define a holding device for a flat element.
