Description

Aus dünnwandigen, koaxialen Blechrohren bestehende Lüftungsleitung mit dazwischenliegendem isolierendem Luftraum Die Erfindung geht aus von einer aus dünnwandigen, koaxialen Blechrohren bestehenden Lüftungsleitung mit dazwischenliegendem isolierendem Luftraum, wobei die beiden koaxialen Blechrohre miteinander lediglich über eine auf den notwendigen Rohrkrümm- und T-Stücken und anderen Verbindungs- und Leitungsstücken angeordnete Ioslierungskonstruktion durch Preßverbindungen verbunden sind.Ventilation line consisting of thin-walled, coaxial sheet metal pipes with an insulating air space in between. The invention is based on one thin-walled, coaxial sheet metal pipes with an existing ventilation duct in between insulating air space, the two coaxial sheet metal tubes with each other only via one on the necessary pipe elbows and T-pieces and other connecting and pipe sections arranged isolation structure connected by pressure connections are.

Die Aufgabe der Erfindung besteht demgegenüber darin, Lüftungsleitungen der soeben genannten Art insoweit zu verbessern, daß die Verbindungsart noch wesentlich vereinfacht wird.In contrast, the object of the invention is to provide ventilation ducts of the type just mentioned to the extent that the type of connection is still essential is simplified.

Zur Lösung dieser Aufgabe ist die Vereinigung folgender Merkmale vorgesehen: a) In an sich bekannter Weise sind die Verbindungsstücke nur mit einem Isolierformstück als Isolierungskonstruktion überzogen.To solve this problem, the combination of the following features is provided: a) In a manner known per se, the connecting pieces are only provided with a molded insulating piece covered as an insulation construction.

b) Das äußere Blechrohr ist mit seinen Enden über die Isolierformstücke gepreßt.b) The outer sheet metal pipe is with its ends over the insulating fittings pressed.

c) Das innere Blechrohr ist mit seinen Enden in die Isolierformstücke gepreßt.c) The inner sheet metal tube is with its ends in the insulating fittings pressed.

Als für die Aufgabenlösung vorteilhafte und förderliche Weiterbildungen sind weitere Merkmale den am Schluß der Beschreibung angeführten Unteransprüchen 2 und 3 zu entnehmen.As further training that is advantageous and conducive to solving tasks are further features of the subclaims listed at the end of the description 2 and 3.

Durch die Erfindung wird so erreicht, daß die Verbindungsart bei Lüftungsleitungen der in Frage stehenden Art wesentlich vereinfacht wird.The invention thus ensures that the type of connection in ventilation ducts of the type in question is significantly simplified.

Die Erfindung wird an Hand eines Ausführungsbeispieles in der Zeichnung näher erläutert.The invention is illustrated using an exemplary embodiment in the drawing explained in more detail.

In der Zeichnung ist die aus dünnwandigen, koaxialen Blechrohren 2, 3 bestehende Lüftungsleitung 1 mit dazwischenliegendem, isolierendem Luftraum 4 zu erkennen. Die beiden koaxialen Blechrohre 2, 3 sind lediglich miteinander über einer auf den notwendigen Rohrkrümmern und T-Stücken und anderen Verbindungs- und Leitungsstücken 5, 6 angeordneten Isolierungskonstruktion 7, 8 verbunden.In the drawing, the ventilation duct 1 consisting of thin-walled, coaxial sheet metal pipes 2, 3 with an insulating air space 4 in between can be seen. The two coaxial sheet metal pipes 2, 3 are only connected to one another via an insulation structure 7, 8 arranged on the necessary pipe bends and T-pieces and other connecting and line pieces 5, 6.

Die Verbindungsstücke 5, 6 sind nur mit einem Isolierformstück 7, 8 als Isolierungskonstruktion überzogen.The connecting pieces 5, 6 are only covered with an insulating molding 7, 8 as an insulating structure.

Das äußere Blechrohr 3 ist mit seinen Enden über die Isolierformstücke 7, 8 gepreßt. Das innere Blechrohr 2 ist mit seinen Enden in die Isolierformstücke 7, 8 gepreßt.The ends of the outer sheet metal tube 3 are pressed over the insulating fittings 7, 8. The ends of the inner sheet metal tube 2 are pressed into the insulating fittings 7, 8.

Die Enden der beiden Blechrohre 2, 3 können auf ihren Innenseiten mit einer Dichtungsmasse überzogen sein.The ends of the two sheet metal tubes 2, 3 can be coated on their insides with a sealing compound.

Das äußere Blechrohr 3 kann etwas kürzer als das innere Blechrohr 2 sein, wobei die beiden Blechrohre 2, 3 durch Kopfnieten 9 miteinander verbunden sind.The outer sheet metal tube 3 can be somewhat shorter than the inner sheet metal tube 2, the two sheet metal tubes 2, 3 being connected to one another by head rivets 9.
