 dgl.Fig. 2 diese Muffenverbindung im Axialschnitt grösseren Massstabes. 



   Zur Verbindung zweier dünnwandiger Blechrohre--1, 2--, wie sie für die Herstellung von
Rauchgaszügen, Dachrinnenabfallrohren od. dgl. Verwendung finden, ist eine gesonderte Muffe --3-- vorgesehen, die eine Sicke --4-- aufweist und bis in den Bereich dieser Sicke auf demeinen Rohr   - -1--   steckt, wobei dieses   Rohr --1-- seinerseits   mit seinem Endabschnitt --5-- unter Aufweitung des   Endes --5a-- in   die   Sicke --4-- eingepresst   ist.

   Das andere   Rohr --2-- lässt   sich nun einfach mit seinem geraden Endbereich --6-- von der freien Seite her in die Muffe --3-- einschieben, bis sein   Ende --6a--,   das zur besseren Abdichtung, wie strichliert angedeutet, angeschliffen sein kann, am ausgebauchten Endbereich --5-- des ersteren   Rohrs --1-- aufsitzt.   Zur Sicherung der Rohrverbindung ist die Muffe --3-- an ihren beiderseits der Sicke --4-- vorhandenen Zylin-   derabschnitten --3a, 3b-- beispielsweise   durch   Punktschweissungen --7-- bzw. Niete --8-- an   den   Rohren--1, 2--befestigt.   



   Es entsteht eine dichte, innen weitgehend glatte und besonders knicksteife Rohrverbindung, die rationell mit einfachen Werkzeugen herstellbar ist und auch ein Zuschneiden der Rohre auf der Bautelle erlaubt. Da die vorhandene Sicke und der ausgebauchte Endabschnitt des einen Rohrs nicht nur zur Verbindung von Muffe und Rohr, sondern auch zur Aufnahme von Dichtmaterial dient, können mit dieser Muffenverbindung Rohre auch gasdicht gestossen werden. 



   PATENTANSPRCHE : 
1. Muffenverbindung für dünnwandige Blechrohre, insbesondere Rauchgasrohre, gekennzeichnet durch eine gesonderte, eine auswärts gebauchte Sicke (4) aufweisende Muffe (3), die einerseits bis zum Sickenbereich auf dem einen, unter Aufweitung seines Endes (5a) in die Sicke (4) eingepressten Rohr   (l)   steckt und anderseits das mit seinem geraden Endbereich (6) bis zum Anstoss 
 EMI2.1 
 schweissungen (7), Niete (8), Schrauben, Klinken an den beiderseits der Sicke (4) verbleibenden Zylinderabschnitten (3a, 3b) der Muffe (3) befestigt sind.

 <Desc / Clms Page number 2>

 Like Fig. 2 this sleeve connection in axial section on a larger scale.



   For connecting two thin-walled sheet metal tubes - 1, 2--, as used for the production of
Flue gas flues, gutter waste pipes or the like are used, a separate sleeve --3-- is provided, which has a bead --4-- and is in the area of this bead on the one pipe - -1--, whereby this pipe --1-- is pressed into the bead --4-- with its end section --5-- while widening the end --5a--.

   The other pipe --2-- can now simply be pushed with its straight end section --6-- into the sleeve --3-- from the free side until its end --6a--, which for better sealing, as indicated by dashed lines, can be grinded, rests on the bulged end area --5-- of the former tube --1--. To secure the pipe connection, the sleeve --3-- is present on the cylinder sections --3a, 3b-- on both sides of the bead --4--, for example by spot welding --7-- or rivets --8-- the pipes - 1, 2 - attached.



   The result is a tight, largely smooth inside and particularly kink-resistant pipe connection, which can be produced efficiently with simple tools and also allows the pipes to be cut to size on the construction site. Since the existing bead and the bulged end section of the one pipe not only serve to connect the sleeve and pipe, but also to accommodate sealing material, pipes can also be butted gastight with this sleeve connection.



   PATENT CLAIMS:
1. Socket connection for thin-walled sheet metal pipes, in particular flue gas pipes, characterized by a separate sleeve (3) with an outwardly bulged bead (4), which on the one hand extends to the bead area on one side, with its end (5a) being expanded into the bead (4) Pressed-in tube (l) and on the other hand with its straight end area (6) up to the abutment
 EMI2.1
 Weldings (7), rivets (8), screws, pawls are attached to the cylinder sections (3a, 3b) of the sleeve (3) remaining on both sides of the bead (4).
