<p>A modular building system for skeletal frames has pillar-like supporting tubes with ridge-like recesses on their outer circumference parallel to their axis, similar to teeth, that interlock with mating profiles at the inner surface of joining elements that can be releasably linked to the supporting tubes. The toothed sector of the bearing profile of the joining elements that meshes with the outer circumference of the supporting tubes has a wrap-around angle of between 60° and 120°. The joining elements are provided with at least one additional tooth-like bearing profile for interlocking with at least one further supporting tube which forms an angle with the first supporting tube.</p> |
