Die vorliegende Erfindung betrifft einen Strangentlüfter aus Kunststoff für Flachdächer, wie er als oberer Abschluß für Sanitär- und sonstige EntlUftungsleltungen bereits bekannt ist. Diese Entlüfter durchstoßen das Flachdach, das üblicherweise mittels verklebten Dachpappen oder fest oder lose verlegten verschweißten oder verklebten Kunststoffbahnen gegen das Eindringen von Feuchtigkeit geschützt wird. Soweit eine Wärmeisolation notwendig ist, wird dies mit wärmedämmenden Glasmattem oder Kunststoffschäumen erreicht. Das wasserdichte Einfügen der die Dachhaut durchstoßenden Entlüfter bereitet naturgemäß Schwierigkeiten, da die geschlossene Dachhaut zu diesem Zweck durchstoßen werden muß. Dies wurde bisher mehr ouer weniger gut dadurch erreicht, daß man die Entlüftungsrohre mit einem handgefertigten oder auch vorfabrizierten Flansch versah, welcher aus klebefähigem Material, wie z.B. Dachpappe, flächigen Bitumenbahnen oder Kunststoff bestand. Der Nachteil lag darin, daß nach dem bisherigen Stande der Technik diese Klebestelle im wasserführenden Teil des Daches lag.The present invention relates to a duct ventilator from Plastic for flat roofs, such as the top finish for Plumbing and other ventilation lines are already known. These ventilators pierce the flat roof, which is usually by means of glued roofing felt or firmly or loosely laid welded or glued plastic sheets against the ingress of moisture is protected. If heat insulation is necessary, this is done with heat-insulating glass mats or plastic foams. The watertight insertion of the ventilators piercing the roof cladding prepares naturally difficulties, since the closed roof skin must be pierced for this purpose. So far this has become more Ouer less well achieved by the fact that the ventilation pipes with a hand-made or prefabricated one Flange, which consisted of adhesive material, such as roofing felt, flat bitumen sheeting or plastic. The disadvantage was that, according to the prior art, this glue point was in the water-bearing part of the roof lay.
Neuerungsgemäß wird dieser Schwierigkeit durch die Konstruktion eines Strangentlüfters begegnet, dessen Nahtteile grundsätzlich mit der Dachhaut verschweißt und im übrigen durch die Art der Ausführung aus dem wasserführenden Bereich herausgehoben werden. Der Neuerungsgemäße Strangentlüfter besteht aus eiern an sich bekannten Anschlußstutzen 4, welcher an seinem oberen und unteren Ende verjüngt ist und direkt in die Entlüftungsleitung eingeschoben werden kann. Auf diesen Stutzen aufgeschoben befindet sich der Schweißflansch 5, welcher zweckmäßigerweise trichterförmig nach unten ausgebildet ist. Der entstehende Hohlraum 3 ist wiederum mit Kunststoff, zweckmäßigerweise jedoch mit Kunststoffschaum ausgefüllt. Auf dem oberen Ende des Anschlußstutzens 4 befindet ,, sich die an ihrem Unterteil aufgeweitete Dunsthaube 1, welcheAccording to the innovation, this difficulty is countered by the construction of a line ventilator, the seam parts of which are basically welded to the roof skin and lifted out of the water-bearing area due to the type of design will. The innovation according to the line vent consists of eggs known connection piece 4, which is tapered at its upper and lower end and can be pushed directly into the vent line. On this The welding flange 5 is pushed on, which is expediently funnel-shaped downwards. The resulting cavity 3 is in turn made of plastic, but expediently filled with plastic foam. Located on the upper end of the connecting piece 4 ,, the widened at its lower part of the hood 1, which
dadurch sowohl Oberteil des Anschlußstutzens 4 als auch desthereby both the upper part of the connecting piece 4 and the
Schweißflansches 5 überlappt. Das Oberteil 2 des Schweißflansches 5 dient gleichzeitig als Dichtung für die aufgesetzte Dunsthaube 1. Damit ist der Straugentlüfter in seiner Gesamtheit gegen das Eindringen von Feuchtigkeit im wasserführenden ■ Bereich als auch gegen Regen geschützt, da der Schweißflansch,Welding flange 5 overlaps. The upper part 2 of the welding flange 5 also serves as a seal for the attached Extractor hood 1. This completes the draft ventilator in its entirety Protected against the ingress of moisture in the ■ water-bearing area as well as against rain, as the welding flange,
welcher notwendigerweise aus dem gleichen schweißbaren ther-which is necessarily made of the same weldable thermal
t moplastischen Material wie die Dachhaut hergestellt sein muß,t thermoplastic material like the roof cladding must be made,

Als verschweißbare Kunststoffe kommen neben weichmacherhaltigem PVC Polyisobutylen und bitumen- oder steinkohlenteer-modifizierte Kunststoffe usw. in Betracht.As weldable plastics come in addition to those containing plasticizers PVC polyisobutylene and modified bitumen or coal tar Plastics etc. into consideration.
