Abstract
A construction set for the erection of support structures comprises supporting rods and at least one connecting joint containing a plurality of mutually parallel chambers. Cylindrical beads are formed on the ends of supporting rods. Those beads are inserted into the cylindrical chambers of the connecting joint. The chambers are dimensioned to form a clearance relative to the beads in order to facilitate the insertion of the beads into the chambers. The beads are formed by a rolling-in of the free ends of the supporting rods.
