ABSTRACT:
A frame construction includes at least one nodal connection element and several tube-shaped frame elements connected thereto. The frame elements and the nodal connection elements are manufactured by hydraulic internal high pressure forming and are joined via plug-type connections. Each nodal connection element has at least two connections for adjoining frame elements. The nodal connection element consists of at least two internal-high-pressure-formed tube-shaped hollow bodies in a nested configuration. The hollow bodies are made of different materials, and have different cuts in the area of the connections--viewed in the longitudinal direction of the respective connection, allowing connection with frame elements made of corresponding different materials. In the area of each connection, one of the two hollow bodies, in addition to being connected in a plug-type connection with the adjoining frame elements made of the same material, is connected by an additional connection.
