Set of structural elements for producing supporting structures, having supporting bars 5 and cylindrical connecting elements 1 for insertion heads 6 provided on the end sides of the supporting bars 5, the connecting elements being provided with a plurality of slots which are open on one side and extend, parallel to one another and to the axis of the cylindrical connecting elements, from the surface to the center, and the slots each being widened, at a distance from the radial ends of the same, to form chambers for receiving the insertion heads. The insertion heads are formed in the flat end regions of the supporting bars, at a distance from the end edges, in that at least two parallel slits are provided at an angle of 90 DEG with respect to the end edge, and, in each case one bead running parallel to the end edge is formed in the strips produced by the slits, and the beads of adjacent strips are respectively formed on mutually opposite sides, with the result that an annular thickening with circular or oval cross section and an outer circumference which corresponds to the cross section of the chamber in the slots of the connecting elements is formed in the region of the flat ends of the supporting bars, parallel to the end side, beside a continuous border strip. |
