FIELD: construction.SUBSTANCE: roof ventilation device includes a hood and a housing with a flat base in the form of a flange, which are made by forming from polymer material. The housing is U-shaped and elevated above the flat base. A grid is formed inside the housing, above which mounting posts are located to fix the hood, as well as a border is located on three sides, in the rear part of which two cavities are formed, which contain plastic elements located vertically and perpendicular to outer surface of the border. The hood is of a round shape with a grid located on the lateral side protected with a funnel, as well as with two convexes on the opposite lateral side, which form cavities at assembly, on the inner surface of which plate-like elements are formed and located vertically and perpendicular to the hood surface. Mounting posts for attachment of the hood to the housing are made on the inner surface of the hood.EFFECT: easier assembly and attachment of the device.5 cl, 4 dwg |
