Tube e.g. window board, for use in building domain, has tubular end for its fixation to support structure by fixation device having interface slid by prehension ring, where space between ring and core is slightly over dimensioned

摘要

The tube (1) has a tubular end (1a) for its fixation to a support structure by a fixation device. The device has a monoblock fixation interface (2) with a support surface (2a) transversal to a direction of sliding the interface by a prehension ring (23). An annular space between the ring and a core (21) is slightly over dimensioned with respect to thickness of a wall of the tube during sliding of the interface with respect to the tube. The prehension unit has the same shape as that of cross section of the tubular end. An independent claim is also included for a method to fix a construction unit with a carrier structure by a fixation device.
