Description

8300402-8 2 10 15 20 25 30 35 opening is designed along the extent of the roof trusses. The fan comprises a hood, which extends along the roof caps and covers the opening between the roof parts of a cover plate, which is arranged to cover the opening below the hood and above The hood is preferably provided: a perforation, which extends at least along its long sides. both the hood and the cover plate comprise two flanks, which join together in a point along the center line of the ridge. The cover plate may be provided with a perforation partly at its tip, partly uured its long sides.

The fan according to the invention is particularly suitable for roof cladding of corrugated sheet metal whose channels extend perpendicular to the ridge, and wherein the corrugated sheet metal channels are provided with a dice at the respective channel below the opening at the ridge. The sealing gene preferably consists of a support of the conruged sheet to a wall along the opening or of strips of callable material such as CORUSAL.

The cover plate is placed with the opening at the ridge so that its perforation along the long side is above the drainage plates.

As a result, condensation can form on the underside of the hood, as well as rain and snow water, which penetrates the perforations of the hood, drip down onto the cover plate and run down the perforation down the long sides and down the drainage plate.

The hood is positioned so that its perforation is substantially above the perforation of the cover plate along the long sides.

The perforation in the hood or cover plate consists of holes so small that larger insects cannot pass through it. In this way it is also achieved that the ventilator does not allow birds to enter the building through the ventilator.

The invention is described in more detail in the following claims, in an exemplary embodiment and in the accompanying figures, in which Figure 1 shows a part of a saddle roof seen obliquely from the outside.

Figure 2 shows a cross section. gencm roof ridge on the roof according to figure 1.

Figure 3 shows the roof part according to figure 2 seen from above.

UfFÖKfbïGäElå fl iPfïr: The saddle roof according to figure 1 is provided with a lined, 1, of corrugated drainage sheet, which extends from the respective eaves and up to the eaves, where an opening, 2, is formed along the extent of the eaves.

The fan according to the invention comprises a hood, 3, which extends below the roof curtain and covers the opening, 2. The hood, 3, comprises two flat flanks, 4, which are each parallel to the respective roof part and which along the long sides are provided with a substantially vertical wall , 5, san connects the respective flank, 4, down one foot, 6, san in turn carries the hood, 3. The hood, 3, 10 15 20 3 8300402-8 is provided with a perforation, 7, which extends along resp flanks, 4, long side.

A cover plate, 8, is arranged so as to cover the opening, 2, below the hood, 3, the cover plate, 8, consisting of two flat flanks, 9, each of which is parallel to the hood, 3, and flank, 4, respectively, and which supports the respective roof part. The cover plate, 8, is provided with a perforation, 10, which extends in an area along its center line and a perforation, 11, which extends in an area along its long side. The cover plate, 8, or side perforation, 11, is arranged vertically below the hood, 3, or perforation, 7, respectively, and on the part of the flat flank, 9, which is located above the roof covering, 1.

Roof bead dies, 1, of corrugated steel sheet: comprises channels extending perpendicular to the ridge and provided with a lip fitting to a sealing wall, 10, on each roof part along the opening, 2.

All perforation is made with ø 3 mnz holes with c / c 6 nm.

With this arrangement, outside air is allowed to flow on the underside of the cladding from the eaves up to the ridge and out through the central perforation in the cover plate and further out through the perforation in the hood down its long sides according to the solid, arrowed lines in figure 2.

Ev. penetrated rain, snow water or condensate from the fan drains down onto the roof covering according to the dashed, arrowed lines in figure 2.

Claims (3)
