In spherical frameworks that are already known, use is made of a connection node which is produced in spherical form and in which provision is made on each outer side for a groove which is open towards one side. Provision has therefore been made for the grooves of the connection node to open out into mutually parallel cylindrical chambers and for the suspension heads for the bars to be produced in the form of increases in thickness, the length of which corresponds to that of the chambers and the transverse section of which is adapted to that of the same chambers, said increases in thickness being arranged at the ends of the load-bearing bars which have been squashed flat. A simple assembly process is achieved in this way, which makes it possible to construct a robust load-bearing structure. |
