Description
Die Erfindung betrifft ein Innenrohr für einen Schornstein nach dem Oberbegriff des Patentanspuchs 1.The invention relates to an inner pipe for a chimney according to the preamble of patent claim 1.
Aus der EP 0 711 954 A2 ist ein entsprechendes Innenrohr bekannt, wobei durch Zusammensetzen mehrerer gleichartiger Innenrohre ein Innenrohrsystem der für den Schornstein erforderlichen Länge gebildet werden kann.A corresponding inner tube is known from EP 0 711 954 A2 known, by assembling several of the same Inner pipes an inner pipe system for the chimney required length can be formed.
Der Erfindung liegt das Problem zugrunde, die Muffe möglichst dünnwandig auszubilden und bei der Montage des Innenrohrsystems Beschädigungen der Rohrenden beim Aufsetzen des nächstfolgenden Innenrohres zu vermeiden.The invention is based on the problem, the sleeve as possible train thin-walled and when installing the Inner pipe system Damage to the pipe ends when fitting to avoid the next inner tube.
Erfindungsgemäß wird die Aufgabe durch die kennzeichneneden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Erfindungsgemäss weist die Muffe einen trichterförmigen Aufsatz auf, dessen Innendurchmesser an dem der Muffe zugewandten Ende maximal gleich dem Innendurchmesser der Muffe und minimal gleich dem Außendurchmesser des freien Endes des Innenrohres ist. Vorteilhafterweise ist der Innendurchmesser des trichterförmigen Aufsatzes etwas kleiner als der Innendurchmesser der Muffe.According to the invention the task is characterized by the Features of claim 1 solved. Advantageous configurations the invention are characterized in the subclaims. According to the invention, the sleeve has a funnel-shaped Attachment, whose inside diameter matches that of the sleeve facing end maximum equal to the inside diameter of the sleeve and minimally equal to the outside diameter of the free end of the Inner tube is. The inside diameter is advantageous of the funnel-shaped attachment is slightly smaller than that Inner diameter of the sleeve.
Bei diesem Innenrohr, das auch für die senkrechte Rohrleitung in einem Luft-Abgas-Schornstein geeignet ist, wird bei der Montage das freie Ende des nächstfolgenden Innenrohres von dem trichterförmigen Aufsatz geführt und zentriert, so daß das freie Ende des eingeführten Innenrohres nicht auf dem Rand der Muffe aufsitzen kann. Dadurch werden Beschädigungen der Muffe und des freien Endes des eingeführten Innenrohres ausgeschlossen. Dies ist vor allem bei Innenrohren wichtig, die aus sprödem, insbesondere aus keramischem Werkstoff bestehen. Infolge der dünnwandigen Ausbildung der Muffe wird bei einem Luft-Abgas-Schornstein ein größtmöglicher Querschnitt des zwischen der Außenfläche der Muffe und der Innenfläche des Schornsteins gebildeten Ringspalts erreicht.With this inner pipe, which is also for the vertical pipe in an air-flue chimney is suitable at the Assemble the free end of the next inner tube from the funnel-shaped attachment guided and centered, so that the free end of the inserted inner tube not on the edge of the Sleeve can sit on. This will damage the sleeve and the free end of the inserted inner tube locked out. This is especially important with inner tubes, the brittle, especially ceramic material consist. As a result of the thin-walled design of the sleeve the largest possible with an air-exhaust chimney Cross section of the between the outer surface of the sleeve and the Reached inner surface of the chimney formed.
Das erfindungsgemäße Innenrohr ist auch besonders gut geeignet zur Sanierung eines vorhandenen Schornsteins. Sofern der im Haus vorhandene Schornstein ausgefräst werden muß, kann das Ausfräsen auf einen relativ kleinen Durchmesser beschränkt werden. Vorteilhafterweise weist die Außenkontur der Muffe einen allmählichen Übergang vom Außendurchmesser des Innenrohres zum Außendurchmesser der Muffe aüf, so daß bei der Sanierung eines vorhandenen Schornsteins beim Absenken des Innenrohrsystems vom Schornsteinkopf her die Muffen nicht an eventuell vorhandenen Vorsprüngen im Schornstein aufsetzen und hängenbleiben können.The inner tube according to the invention is also particularly suitable for the renovation of an existing chimney. If the in The existing chimney must be milled out Milling limited to a relatively small diameter become. The outer contour of the sleeve advantageously has a gradual transition from the outside diameter of the Inner tube to the outer diameter of the sleeve, so that the Refurbishment of an existing chimney when lowering the Inner pipe system from the chimney head not on the sleeves any protrusions in the chimney and can get stuck.
Eine gasdichte Ausführung des Innenrohrsystems wird erreicht, wenn bei der Montage eine Dichtungsmasse wie Silikonkunststoff oder Säurekitt in die Muffe bzw. auf die Stirnfläche des freien Endes des eingeführten Innenrohres aufgebracht wird, so daß dieses Material die Fuge schließt.A gas-tight design of the inner pipe system is achieved if a sealant such as silicone plastic is used during assembly or acid putty in the sleeve or on the face of the free end of the inserted inner tube is applied, so that this material closes the joint.
Vorzugsweise ist die trichterförmige Fläche des Aufsatzes kegelstumpfförmig ausgeführt, wobei der Basiswinkel des Kegelstumpfs mehr als 45° beträgt, vorzugsweise etwa 60°.The funnel-shaped surface of the attachment is preferably frustoconical, the base angle of the Truncated cone is more than 45 °, preferably about 60 °.
Der trichterförmige Aufsatz kann als dünnwandiger Stutzen ausgeführt sein, welcher oberhalb der Muffe eine nach innen weisende Sicke aufweist, die im Querschnitt vorzugsweise ein sägezahnförmiges Profil aufweist.The funnel-shaped attachment can be used as a thin-walled nozzle be carried out, which above the sleeve one inside has facing bead, which preferably in cross section has a sawtooth profile.
Der Stutzen kann aus dünnwandigem Metallblech ausgeführt sein, vorzugsweise aus rostfreiem Stahl.The nozzle can be made of thin-walled sheet metal, preferably made of stainless steel.
Die dünnwandige Muffe wird beim Transport und der Montage besonders gut geschützt, wenn der Stutzen eine die Muffe umgebende Manschette aufweist. The thin-walled sleeve is used during transport and assembly particularly well protected if the socket is a sleeve has surrounding cuff.
Der Stutzen wird auf der Muffe sicher befestigt, wenn im Bereich der Manschette nach innen weisende Klemmlaschen vorgesehen sind. Dadurch können Toleranzen ausgeglichen werden.The connector is securely attached to the sleeve when in Area of the cuff with clamping tabs pointing inwards are provided. This can compensate for tolerances become.
Eine Zentrierung des Innenrohrsystems in radialer Richtung im Schornstein wird erreicht, wenn zwischen einem Innenrohr und dem Schornstein Zentrierelemente vorgesehen sind. Vorteilhafterweise sind am trichterförmigen Aufsatz wenigstens drei über den Umfang verteilte Zentrierelemente vorgesehen.A centering of the inner pipe system in the radial direction in Chimney is reached when between an inner pipe and the chimney centering elements are provided. Advantageously, at least on the funnel-shaped attachment three centering elements distributed over the circumference are provided.
Ungleichmäßigkeiten des Ringspalts zwischen Innenrohr und Schornstein können die Zentrierelemente ausgleichen, wenn sie elastisch federnd ausgebildet sindIrregularities in the annular gap between the inner tube and Chimney can compensate for the centering elements if they are designed to be resilient
Das aus den Innenrohren hergestellte Innenrohrsystem ist für große Bauhöhen besonders geeignet, weil die Zentrierelemente in axialer Richtung im Schornstein gleiten können, so daß infolge temperaturbedingter Längendehnung der Innenrohre keine mechanischen Spannungen auftreten.The inner tube system made from the inner tubes is for Large heights particularly suitable because of the centering elements can slide in the axial direction in the chimney, so that none due to the temperature-related elongation of the inner tubes mechanical stresses occur.
Die Zentrierelemente können mit dem Innenrohr lose mitgeliefert und erst auf der Baustelle mit diesem verbunden werden, wenn der Stutzen über die Sicke hinaus verlängert ist und in dem verlängerten Abschnitt Aufnahmen für die Zentrierelemente aufweist.The centering elements can be loose with the inner tube supplied and only connected to it at the construction site if the nozzle is extended beyond the bead and in the extended section recordings for the Has centering elements.
Die Montage eines Zentrierelements ist besonders einfach, wenn eine Aufnahme und ein Ende eines Zentrierelements als ineinandergreifende Rastverbindungen ausgebildet sind.The assembly of a centering element is particularly simple if a receptacle and an end of a centering element as interlocking locking connections are formed.
In der Zeichnung ist ein bevorzugtes Ausführungsbeispiel der Erfindung dargestellt, das im folgenden näher erläutert wird.In the drawing, a preferred embodiment of the Invention shown, which is explained in more detail below.
