Abstract (en)

[origin: EP0949391A2] Two opposing fasteners (13,14) are slidably mounted beneath a roofing slab (2) around the outer surface (5) of a tube (4) forming the ventilation pipe (1), and can be clamped against the underside (12) of the slab. The ventilation pipe extends through an opening in the slab. Supports (6) mounted on the outside of the tube part of the pipe rest on top of slab edges (10,11) located above the slab opening. The fasteners are shells with a profiling (17,18), which mates with corresponding profiles extending over the length of the outer tube surface. Independent claims are also included for (a) the ventilation pipe, and (b) the roofing slab.
