An assembly system for mounting lateral beams on a central beam to form a framework in which the central beam is provided with laterally extending, preferably cylindrical pegs, which are formed with inclined bearing surfaces, e.g. conical surfaces, adjacent their free ends. The lateral beams have bores formed therein into which the pegs fit, and transversely extending screws having conical ends are screwed against the inclined bearing surfaces to press the lateral beams against the central beam. |
