Beschreibung
Zusammenfassung:	Disclosed is a fire-rated ventilation duct structure penetration arrangement comprising a ventilation duct and a building structure, such as a wall, ceiling or floor, through which the ventilation duct extends, said ventilation duct comprising one or more metal sheets forming said duct, wherein said metal sheet duct is covered on the outside by a fire protection material, and said duct includes elongated stiffening members located on the outside of the duct and attached to said metal sheets, where the stiffening members are arranged substantially within the opening of the building structure. L'invention concerne un agencement de pénétration de structure de conduit de ventilation coupe-feu comprenant un conduit de ventilation et une structure de bâtiment, telle qu'une paroi, un plafond ou un plancher, à travers lequel s'étend le conduit de ventilation, ledit conduit de ventilation comprenant une ou plusieurs feuilles métalliques formant ledit conduit, ledit conduit de feuille métallique étant recouvert sur l'extérieur par un matériau de protection contre l'incendie, et ledit conduit comportant des éléments de raidissement allongés situés sur l'extérieur du conduit et fixés auxdites feuilles métalliques, les éléments de raidissement étant agencés sensiblement à l'intérieur de l'ouverture de la structure de bâtiment.
