Definitions

  • the present invention relates to a ventilator intended for removal at the top of air from the under-side of a ventilated roof covered with preferably trapezoidally shaped run-off panels.
  • run-off panels are often shaped with ridges and grooves in the direction of the roof's inclination. Towards the top the inclined areas of the roof meet in ridges, for instance in the case of pitched roofs and hipped roofs. It is desirable for the said run-off panels to be maintained in one way or another at or close to the temperature of the external air. The principal reason for this consists in the fact that snow on the roof must not melt and the water therefrom must not run down and freeze to ice at the base of the roof. If this happens accidents may be caused as a result of falling bits of ice. The melt water may also accumulate in front of these walls of ice and penetrate the house through the joints between the roof panels.
  • a good method of maintaining the roof panels at a temperature close to that of the external air consists in allowing external air to rise by natural draft below the roof panels and to be allowed to escape at the top in the ridge area. It has however proved difficult to achieve simple and cheap ventilation in the ridge area, enabling such air to escape while at the same time preventing rain and snow from being blown under the roof covering while likewise eliminating any possibility of birds and insects getting in and causing damage.
  • the German patent publication DE 2430 959 describes a ventilator for a ridge of a building which only is comprising a cap for an opening along a ridge at a roof covered by shaped plates.
  • the cap is provided with walls along its sides which are supporting against the ridges between the grooves and also provided with sealings projecting downward from the cap into the grooves just in the area at the walls of the cap.
  • a disadvantage with this ventilator is that its ability to let the air inside the building to pass out is restricted by the area of the grooves.
  • condense which is forming on the under-side of the cap, will fall down upon the shaped plate and accumulate above the sealings and even pass through the opening at the ridge between the two shaped plates.
  • Another disadvantage with this ventilator is that it is not provided with a netting or a perforated plate to prevent insects and birds from passing into the building.
  • the ventilator comprises a cap extending along the ridge of the roof and covering the opening between the roof sections and a cover plate so arranged as to cover the opening below the cap and above the roof panels.
  • the cap is preferably provided with a perforation extending at least along its longitudinal sides. Both the cap and the cover plate have two flanks meeting in an apex along the centre line of the ridge of the roof.
  • the cover plate may be provided with a perforation both at its apex and along its longitudinal sides.
  • the ventilator in accordance with the invention is especially suitable at roof coverings consisting of shaped panels, the grooves of which extend at right angles in respect of the ridge of the roof, whereby each groove of the shaped panel is provided with sealing facing along the ridge opening.
  • the sealings is brought about preferably by jolting the chaped plate so as to achieve a wall along the opening or by means of strips of a compressible material.
  • the cover plate is located along the ridge opening so that its perforation along the longitudinal sides is above the run-off panels.
  • the cap is so located that its perforation is substantially above the cover plate perforation along the longitudinal sides.
  • the perforations in the cap and cover plate respectively consist of holes so small that relatively large insects cannot pass through. This also ensures that the ventilator does not permit birds to enter the building through the ventilator.
  • the pitched roof in accordance with figure 1 is provided with a covering 1 of shaped run-off panels extending from the respective eaves up towards the ridge of the roof where an opening, 2, is provided along the extend of the ridge.
  • the ventilator in accordance with the invention comprises a cap, 3, extending along the ridge of the roof and covering the opening, 2.
  • the cap, 3, comprises two flat flanks, 4 each of which is parallel with the respective section of the roof and provided along the longitudinal sides with a substantially vertical wall, 5, connecting the respective flank, 4, with a base, 6, which in turn supports the cap, 3.
  • the cap, 3, is provided with a perforation, 7, extending along the longitudinal side of the respective flank, 4.
  • a cover plate, 8, is so arranged as to cover the opening, 2, below the cap, 3, whereby the cover plate, 8, consists of two flat flanks, 9, each of which is parallel with the respective flank, 4, of the cap, 3, and abuts the respective section of the roof.
  • the cover plate, 8, is provided on the one hand with a perforation, 10, extending in a zone along its centre line and partly with a perforation, 11, extending in a zone along its longitudinal side.
  • the respective side perforation, 11, of the cover plate, 8, is arranged vertically below the respective perforation, 7, of the cap, 3, and on the part of the flat flank, 9, which is above the roof covering, 1.
  • the roof covering, 1, of shaped steel panels comprises groves, each extending at a right angle to the ridge of the roof and provided with an area jolted u so as to form a sealing wall, 12, on either roof section along the opening, 2.
  • the entire perforation consists of 3 mm dia. holes at 6 mm centre distance.

Abstract

Ventilateur situé au faîte du toit d'un bâtiment conçu pour permettre l'évacuation de l'air extérieur qui, en raison de courants d'air naturels, monte jusque vers le faîte du toit sur le côté inférieur de panneaux d'écoulement profilés (1). Il est formé essentiellement, d'une part, d'une plaque de couverture (8) composée de deux flancs se rejoignant au-dessus d'une ouverture (2) pratiquée au faîte entre des panneaux d'écoulement opposés (1) et, d'autre part, d'un chapeau (3) situé au-dessus de ladite plaque de couverture (8). Un espace existe entre la plaque de couverture (8) et le chapeau (3). Le chapeau (3) est perforé sur ses bords inférieurs s'étendant au-dessus des panneaux d'écoulement opposés (1). La plaque de couverture (8) possède également des rangées perforées à angle droit en-dessous des perforations du chapeau (3), ainsi qu'une perforation au sommet dans la zone du faîte. Aux extrémités supérieures des panneaux d'écoulement, à l'opposé du faîte du toit, un joint d'étanchéité est prévu entre lesdits panneaux et la plaque de couverture (8).

Claims (2)
