The exhaust pipe is in the form of a flexible bellows tube (4) for most of its length. This part of it is held in the shaft by spring spacers (5), so that there is an all-round clearance between it and the shaft wall (6).

Description

Die Erfindung betrifft eine Abgasleitung für Brenngeräte in Gebäuden, mit einem aus Kunststoff bestehenden, in einem Leitungsschacht angeordneten Abgasleitungsstrang, der mit einem Schachtkopf verbunden ist.The invention relates to an exhaust pipe for burning equipment in buildings, with an existing plastic, arranged in a duct exhaust line, which is connected to a shaft head.

Derartige Abgasleitungen dienen zur Abführung der Abgase von Brenngeräten, beispielsweise Gebäudeheizungen. Die Abgasleitungen bestehen üblicherweise aus mehreren Rohrabschnitten, die auf der Baustelle an Muffenverbindungen zusammengesteckt werden, um den Abgasleitungsstrang in der jeweils erforderlichen Länge herzustellen. Für den Transport und die Lagerhaltung dieser Rohrabschnitte wird verhältnismäßig viel Raum beansprucht. Die Handhabung der Rohrabschnitte auf der Baustelle ist umständlich und mit erheblichem Arbeitsaufwand verbunden. Oftmals müssen die einzelnen Rohrabschnitte auf der Baustelle auf das jeweils erforderliche Längenmaß abgelängt werden, was ebenfalls mit zusätzlichem Arbeitsaufwand verbunden ist.Such exhaust pipes are used to dissipate the exhaust gases of burning equipment, such as building heaters. The exhaust pipes usually consist of several pipe sections, which are put together on the construction site of sleeve joints to produce the exhaust pipe string in the required length. For the transport and storage of these pipe sections relatively much space is claimed. The handling of the pipe sections on the site is cumbersome and associated with considerable work. Often, the individual pipe sections must be cut to the required length measure on site, which is also associated with additional work.

Aus DE 1 296 900 A ist ein ausziehbarer und zusammenschiebbarer Kunststoffschlauch mit einer Anzahl ringförmigen Wellungen bekannt, wobei die Wellungen bistabile Eigenschaften aufweisen.Out DE 1 296 900 A is an extendable and collapsible plastic tube with a number of annular corrugations known, the corrugations have bistable properties.

Aus US 5 393 260 A ist es bekannt, eine Abgasleitung eines gasbetriebenen Gerätes als Kombination von zwei konzentrisch angeordneten Profilrohren auszugestalten.Out US 5,393,260 It is known to design an exhaust pipe of a gas-powered device as a combination of two concentrically arranged profile tubes.

Durch die gegenläufige spiralförmige Profilierung wird sichergestellt, dass das innere Profilrohr kontinuierlich einen vorgegebenen Abstand zu dem äußeren Profilrohr einhält.By the opposite spiral-shaped profiling ensures that the inner profile tube continuously maintains a predetermined distance from the outer profile tube.

Aus US 5 165 732 A ist es bekannt, die Verbindungsleitung zwischen einem gasbetriebenen Brenngerät und einem Abgasleitungsstrang in einem Leitungsschacht überwiegend als flexibles Faltenbalgrohr auszugestalten.Out US 5 165 732 A It is known to design the connecting line between a gas-fired burner unit and an exhaust pipe line in a duct mainly as a flexible bellows pipe.

Aus WO 95/12784 A sowie aus WO 95/16873 A ist es bekannt, Abschnitte eines Abgasleitungsstrangs in einem Leitungsschacht als flexibles Profilrohr auszugestalten. In beiden Fällen wird erreicht, dass die flexiblen Abschnitte der Verbindungsleitung, bzw. des Abgasleitungsstrangs an den tatsächlichen Leitungsverlauf und die räumlichen Vorgaben, bzw. Einschränkungen wie beispielsweise ein seitlicher Versatz innerhalb des Verlaufs des Abgasleitungsstrangs leicht angepasst werden können. Eine einfache Längenänderung, bzw. Längenanpassung des Abgasleitungsstrangs ist nicht, bzw. lediglich eingeschränkt möglich.Out WO 95/12784 A as well as out WO 95/16873 A It is known to design sections of an exhaust pipe string in a duct as a flexible profile tube. In both cases it is achieved that the flexible sections of the connecting line, or the exhaust pipe line to the actual line course and the spatial requirements, or restrictions such as a lateral offset within the course of the exhaust pipe string can be easily adjusted. A simple change in length, or length adjustment of the exhaust pipe string is not, or only partially possible.

Aufgabe der Erfindung ist es daher, eine Abgasleitung der eingangs genannten Gattung so auszugestalten, daß sie mit geringem Raumbedarf gelagert und transportiert werden kann, daß die Montage wesentlich vereinfacht ist und aufwendige Maßnahmen zur Längenanpassung entfallen.The object of the invention is, therefore, an exhaust pipe of the type mentioned in such a way that it can be stored and transported with little space required that the assembly is much easier and expensive measures for length adjustment accounts.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Abgasleitungsstrang im überwiegenden Teil seiner Länge aus einem flexiblen Faltenbalgrohr besteht, welches aus flexibel miteinander verbundenen konischen Balgringen besteht, wobei jeder Balgring ein bistabiles elastisches Element bildet.This object is achieved in that the exhaust pipe string in the majority of its length consists of a flexible Faltenbalgrohr, which consists of consists of flexibly interconnected conical Balgringen, each Balgring forms a bistable elastic element.

Das Faltenbalgrohr weist im zusammengeschobenen Zustand nur eine geringe Länge auf und kann daher mit geringem Raumbedarf gelagert und transportiert werden. Erst auf der Baustelle wird das Faltenbalgrohr auf die jeweils erforderliche Länge auseinander gezogen. Dadurch entfällt die Notwendigkeit einer Längenanpassung.The Faltenbalgrohr has only a small length in the collapsed state and can therefore be stored and transported with minimal space requirements. Only at the construction site, the bellows tube is pulled apart to the required length. This eliminates the need for length adjustment.

Durch die Ausgestaltung des Faltenbalgrohrs aus flexibel miteinander verbundenen bistabilen Balgringen wird erreicht, dass das Faltenbalgrohr in jeder vorgegebenen Länge einen stabilen Zustand ohne wesentliche elastische Längskräfte einnimmt. Jeder konische Balgring hat zwei stabile Stellungen, so dass benachbarte Balgringe entweder in einem angenähert vorgegebenen Winkel zueinander angeordnet sind, wobei mehrere Balgringe einen Faltenbalg bilden, oder flach aneinander liegen und einen Block von Balgringen bilden.The design of the bellows tube of flexibly interconnected bistable bellows rings ensures that the Faltenbalgrohr occupies a stable state without significant elastic longitudinal forces in each predetermined length. Each conical bellows ring has two stable positions, so that adjacent bellows rings are arranged either at an approximately predetermined angle to each other, wherein a plurality of bellows rings form a bellows, or lie flat against each other and form a block of bellows rings.

Die jeweils wirksame Länge eines Faltenbalgrohrs ergibt sich daraus, welcher Anteil seiner Balgringe in dieser genannten Weise einen Faltenbalg oder einen Block bildet. Durch Aufbringen von Zugkräften oder Druckkräften in Längsrichtung kann diese wirksame Länge des Faltenbalgrohrs verändert werden.The respective effective length of a bellows tube results from what proportion of its bellows rings in this manner a bellows or a block. By applying tensile forces or compressive forces in the longitudinal direction, this effective length of the Faltenbalgrohrs can be changed.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß der Abgasleitungsstrang zumindest in seinen aus dem flexiblen Faltenbalgrohr bestehenden Längenabschnitten durch federnde Abstandhalter im Leitungsschacht mit allseitigem Abstand zur Schachtinnenwand gehalten ist. Damit wird erreicht, daß das Faltenbalgrohr trotz seiner seitlichen Flexibilität die gewünschte zentrale konzentrische Anordnung im Leitungsschacht einnimmt. Der zwischen dem Abgasleitungsstrang und der Schachtinnenwand bestehende Mantelraum kann hierbei in herkömmlicher Weise zur Zufuhr von Verbrennungsluft zu dem Brenngerät verwendet werden.According to a preferred embodiment of the invention, it is provided that the exhaust pipe line at least in its existing from the flexible Faltenbalgrohr Length sections is held by resilient spacers in the duct with all-round distance to the shaft inner wall. This ensures that the bellows tube occupies the desired central concentric arrangement in the duct despite its lateral flexibility. The jacket space existing between the exhaust-gas line section and the shaft inner wall can in this case be used conventionally for supplying combustion air to the combustion device.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung näher erläutert, das in der Zeichnung dargestellt ist. Es zeigt:

  • Fig. 1 in einem senkrechten Schnitt eine Abgasanlage für ein Gebäude mit einer Abgasleitung für ein Brenngerät,
  • Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1 und
  • Fig. 3 ein Faltenbalgrohr, teilweise im Schnitt.
An embodiment of the invention will be explained in more detail, which is shown in the drawing. It shows:
  • 1 is a vertical section of an exhaust system for a building with an exhaust pipe for a burner,
  • Fig. 2 is a section along the line II-II in Fig. 1 and
  • Fig. 3 is a bellows tube, partially in section.

Fig. 1 zeigt in einem senkrechten Schnitt einen Leitungsschacht 1 in einem Gebäude, der einen Abgasleitungsstrang 2 aufnimmt, der mit einem Schachtkopf 3 verbunden ist.Fig. 1 shows in a vertical section a duct 1 in a building which receives an exhaust duct 2, which is connected to a shaft head 3.

Der Abgasleitungsstrang 2 besteht im überwiegenden Teil seiner Länge aus einem flexiblen Faltenbalgrohr 4 aus Kunststoff, dessen Aufbau in Einzelheiten anhand der Fig. 3 beschrieben ist.The exhaust pipe line 2 consists in the majority of its length of a flexible bellows 4 made of plastic, the structure of which is described in detail with reference to FIG.

Der Abgasleitungsstrang 2 wird in seinen aus dem flexiblen Faltenbalgrohr 4 bestehenden Längenabschnitten durch federnde Abstandhalter 5 im Leitungsschacht 1 mit allseitigem Abstand zur Schachtinnenwand 6 gehalten und zentriert.The exhaust pipe string 2 is held and centered in its consisting of the flexible Faltenbalgrohr 4 longitudinal sections by resilient spacers 5 in the duct 1 with allseitigem distance to the shaft inner wall 6.

Wie in Fig. 1 dargestellt, ist im Abgasleitungsstrang 2 beispielsweise ein Revisionsformstück 6 angeordnet, das einen seitlichen, durch eine Öffnung 7 des Leitungsschachts 1 zugänglichen Schraubdeckel 8 aufweist.As shown in Fig. 1, a revision fitting 6 is arranged in the exhaust pipe string 2, for example, which has a lateral, accessible through an opening 7 of the conduit 1 screw cap 8.

An seinem unteren Ende ist der Abgasleitungsstrang 2 mit einem Rohrknie 9 einer Anschlußleitung 10 verbunden, die zu einem (nicht dargestellten) angeschlossenen Brenngerät führt.At its lower end, the exhaust pipe line 2 is connected to a pipe elbow 9 of a connecting line 10, which leads to a (not shown) connected burning device.

Wie in Fig. 3 dargestellt, weist jedes Faltenbalgrohr 4 zwischen einer Anschlußmuffe 11 und einem Anschlußstutzen 12 einen flexiblen Faltenbalgabschnitt 13 auf, der im wesentlichen aus flexibel miteinander verbundenen konischen Balgringen 14 aus Kunststoff besteht. Jeder Balgring 14 bildet ein bistabiles elastisches Element. Benachbarte Balgringe 14 können daher entweder in einem im wesentlichen vorgegebenen Winkel zueinander angeordnet sein, wie dies in Fig. 3 in einem Bereich 15 dargestellt ist, wobei die Balgringe 14 einen elastischen Faltenbalg bilden, oder die Balgringe 14 können im wesentlichen flach aufeinander liegen und in einem Abschnitt 16 einen axial im wesentlichen starren Block bilden. Die wirksame Länge des Faltenbalgrohrs 4 kann bei der Montage in sehr einfacher Weise dadurch bestimmt werden, daß in axialer Richtung eine Zugkraft oder Druckkraft auf das Faltenbalgrohr 4 ausgeübt wird, so daß ein mehr oder weniger großer Anteil seiner Balgringe 14 aus der Faltenbalganordnung wie im Bereich 15 in die Blockanordnung wie im Bereich 16 und umgekehrt übergeht. Das Faltenbalgrohr 4 ist in jeder der gewählten Längen im wesentlichen stabil, läßt jedoch eine axiale Längenänderung durch elastische Verformungen zu.As shown in Fig. 3, each Faltenbalgrohr 4 between a connecting sleeve 11 and a connecting piece 12 to a flexible bellows portion 13, which consists essentially of flexibly interconnected conical Balgringen 14 made of plastic. Each bellows ring 14 forms a bistable elastic element. Adjacent bellows rings 14 may therefore be arranged either at a substantially predetermined angle to each other, as shown in Fig. 3 in a region 15, wherein the bellows rings 14 form an elastic bellows, or the bellows rings 14 may lie substantially flat on each other and in a portion 16 form an axially substantially rigid block. The effective length of the bellows 4 can be determined during assembly in a very simple manner that in the axial direction of a Traction or compressive force is exerted on the bellows 4, so that a more or less large proportion of its bellows rings 14 from the Faltenbalganordnung as in the area 15 in the block assembly as in the area 16 and vice versa passes. The bellows tube 4 is substantially stable in each of the selected lengths, but allows for an axial length change by elastic deformations.

Der Abgasleitungsstrang 2 ist von dem Schachtkopf 3 des Leitungsschachts 1 abgehängt. Das aus dem Schachtkopf 3 herausgeführte, das obere Ende des Abgasleitungsstrangs 2 bildende Rohrstück 17 ist mit einem Tragstern 18 entweder einstückig oder über ein Gewinde verbunden. Die einzelnen Arme 19 des Tragsterns 18 sind in Ausnehmungen 20 eines zylindrischen Rohrstücks 21 eingehängt, das mit einem Kragen 22 auf der Oberseite des Leitungsschachts 1 ruht.The exhaust pipe line 2 is suspended from the shaft head 3 of the duct 1. The led out of the shaft head 3, the upper end of the exhaust pipe 2 forming pipe section 17 is connected to a support star 18 either in one piece or via a thread. The individual arms 19 of the support star 18 are suspended in recesses 20 of a cylindrical tubular piece 21 which rests with a collar 22 on the top of the duct 1.
