ABSTRACT:
A framework is formed from a plurality of thin-walled, round composite fiber rods having a pressure-resistant foam core and walls. The walls include at least one layer of axially parallel fibers. The framework is constructed from strut rods, transverse rods and joint plates which are operative for connecting the strut rods to the transverse rods. The joint plates are formed from a composite fiber material. Axially parallel recesses are provided in the walls of the strut rods, and the recesses have a width corresponding to the thickness of the joint plates. The recesses extend diagonally through the foam core of the strut rods, and the joint plates are inserted into the recesses where they are glued in place. The transverse rods are provided with slots in the ends thereof. The joint plates are inserted into the slots and glued to join the strut rods to the transverse rods.
