<p>The system comprises, for example, tubular framework elements T1, T2 which can be assembled together, via their ends, perpendicularly with one another, with the aid of mechanical joining elements such as O12. Profiled sections U1, U2 are fastened respectively on the flat sides of the framework elements, forming kinds of frames so as to be able to be engaged in these profiled sections U1, U2, and, if appropriate, to fix therein the ends of bars B11, B21, B22. The invention permits the assembly of highly diverse objects without welding, adhesive bonding or drilling. <IMAGE></p> |
