Description

Die Erfindung betrifft einen Kaminansc'" : ür ein Rauchgasrohr, mit einem Kompensatoi (Dehnungsausgleicher), dessen e'nes End< Rauchgasrohr befestigt ist und dessen an kaminseitiges Ende einen radial vorstehenden Flansch aufweist, der mittels an seiner rückwärtigen Fläche angreifender Klemmteile mit seiner frontseitigen Stirnfläche abdichtend angepreßt ist, wobei der den seitlichen Einlaß des Kamins umgebende, aus Mauerwerk bzw. Futtersteinen bestehende Kaminteil mit einer im wesentlichen ebenen Fläche ausgebildet ist.The invention relates to a Kaminansc '": ÜR a flue gas pipe with a Kompensatoi (bellows) whose e' nes End <flue gas tube is fixed and which has a radially projecting flange of chimney-side end, which attacking means back to its surface clamping parts front with its End face is pressed sealingly, the chimney part surrounding the side inlet of the chimney, consisting of masonry or lining stones, being formed with an essentially flat surface.

Bei einem bekannten Kaminanschluß dieser Art (DE-U-7 116 114) ist der kaminseitige Flansch des Kompensators unter Zwischenfügung einer Dichtung, mittels Spannringen an einen Flansch eines Rohrstutzens angepreßt, der mit seinem Ende zwischen die beiden Wandungen eines doppelten Rauchrohrfutters einsteht, an seinem äußeren Umfang durch einen Asbestschnurring gegen die Innenfläche der äußeren Wandung abgedichtet ist und mit seiner Stirnseite durch eine Asbestringdichtung gegen den ringförmigen Boden abgedichtet ist, der die innere mit der äußeren Wandung verbindet. Die äußere Wandung dieses Rauchrohrfutters ist im seitlichen Einlaß des Kamins gehalten und weist einen radial nach außen vorstehenden Flansch auf, der unter Zwischenfügung von.Mörtel bzw. einer Dichtung die im wesentlichen ebene Fläche übergreift, welche den seitlichen Einlaß umgibt.In a known chimney connection of this type (DE-U-7 116 114) the chimney-side flange of the compensator, with the interposition of a seal, is pressed by means of clamping rings onto a flange of a pipe socket, the end of which protrudes between the two walls of a double flue pipe liner, on his outer circumference is sealed by an asbestos cord ring against the inner surface of the outer wall and its end face is sealed by an asbestos ring seal against the annular bottom, which connects the inner to the outer wall. The outer wall of this smoke pipe lining is held in the side inlet of the chimney and has a radially outwardly projecting flange which, with the interposition of mortar or a seal, engages over the essentially flat surface which surrounds the side inlet.

Durch unterschiedliche Wärmedehnung des Kamins, des Rauchrohrfutters und des Rohrstutzens können sich diese lockern und es können sich Leckstellen ergeben. Zwischen der inneren Wandung des Rauchrohrfutters und dem Rohrstutzen verbleiben taschenartige Hohlräume, in denen sich aggresives Kondensat ablagern kann. Zur Vermeidung von Korrosion durch das Kondensat und dem Angriff der Rauchgase wird es erforderlich, den ohnehin schon konstruktiv aufwendigen Kaminanschluß aus teuerem korrosionsbeständigem Material zu fertigen.Due to different thermal expansion of the chimney, the flue pipe lining and the pipe socket, these can loosen and leak points can result. Between the inner wall of the smoke pipe lining and the pipe socket there remain pocket-like cavities in which aggressive condensate can accumulate. To avoid corrosion by the condensate and the attack of the flue gases, it is necessary to manufacture the already structurally complex chimney connection from expensive corrosion-resistant material.

Ein anderer bekannter Kaminanschluß enthält einen aus L-förmigen Profilen geschweißten Rahmen, der mit einem rohrförmigen Abschnitt unter Belassung eines Radialspiels in den seitlichen Einlaß des Kamins einsteht und mit einem im wesentlichen ebenen Flansch unter Zwischenfügung von Keramikfaser-Material an den Randbereich des Kamineinlasses durch Schrauben angepreßt ist. Der Zwischenraum zwischen dem rohrförmigen Abschnitt und den Kamineinlaß ist mit eingestemmten Asbestschnüren ausgefüllt und durch eine Dichtmasse abgeschlossen. Der rohrförmige Abschnitt des Rahmens setzt sich nach außen fort und endigt in einem radial nach außen vorstehenden Flanschteil, an welchem ein ebenfalls radial nach außen vorstehender Flansch des Kompensators mit Klemmleisten gehalten ist, dessen anderes Ende in gleicher Weise am Rauchgasrohr befestigt ist.Another known chimney connection contains a frame welded from L-shaped profiles, which projects with a tubular section leaving radial play in the side inlet of the chimney and with a substantially flat flange with the interposition of ceramic fiber material at the edge region of the chimney inlet by means of screws is pressed. The space between the tubular section and the chimney inlet is filled with asbestos cords and sealed with a sealing compound. The tubular section of the frame continues outwards and ends in a radially outwardly projecting flange part, on which a likewise radially outwardly projecting flange of the compensator is held with clamping strips, the other end of which is attached in the same way to the flue gas pipe.

Wegen der starken Korrosionswirkung der Rauchgase und der mitgeführten bzw. abgelagerten aggresiven Kondensats war es erforderlich, den erwähnten Rahmen aus Edelstahl auszuführen, so daß der bekannte Kaminanschluß einen erheblichen Investitionsaufwand erfordert. Auch erwiesen sich große Anpreßkräfte als erforderlich, um dem Keramikfaser-Material eine gewisse Dichtwirkung zu verleihen, was aber andererseits zu einer überhöhten Beanspruchung der Futtersteine führte. Durch die unterschiedliche Ausdehnung des Rahmens relativ zum Kamineinlaß bei Betriebswechseln war überdies die Gefahr einer Lockerung und damit einer Undichtigkeit gegeben.Because of the strong corrosion effect of the flue gases and the aggresive condensate carried along or deposited, it was necessary to make the stainless steel frame mentioned, so that the known chimney connection requires a considerable investment. Large contact forces also proved to be necessary in order to impart a certain sealing effect to the ceramic fiber material, but this, on the other hand, led to excessive stress on the lining stones. Due to the different expansion of the frame relative to the chimney inlet when changing operations, there was also the risk of loosening and thus of a leak.

Aufgabe der Erfindung ist es, einen kostengünstig herstellbaren Kaminanschluß zu schaffen, der die Abdichtungsprobleme beseitigt und die Futtersteine bzw. das Mauerwerk des Kamins nur geringen Kräften aussetzt.The object of the invention is to provide a chimney connection which can be produced cost-effectively, which eliminates the sealing problems and exposes the casing stones or the masonry of the chimney to only slight forces.

Diese Aufgabe wird bei einem Kaminanschluß der eingangs genannten Art dadurch gelöst, daß der kaminseitige Flansch des Kompensators einen von seiner frontseitigen Fläche vorstehenden umlaufenden Wulst aufweist, daß in der ebenen Fläche des Kaminteils unter Einhaltung eines Abstandes zum Einlaß eine umlaufende, im wesentlichen komplementär zum Wulst geformte Nut ausgebildet ist und daß der Flansch nur durch eine zwischengeschaltete Schicht aus gummielatischem Material unmittelbar am Mauerwerk bzw. den Futtersteinen anliegt und durch radial außerhalb des Flansches angeordnete, im Mauerwerk bzw. den Futtersteinen gehaltene Schraubverbindungen, sowie Klemmteilen angepreßt ist, welche den Bereich des Wulstes überdecken, wobei der Wulst in die Nut einsteht und die Schicht in klebender Verbindung sowohl mit dem Mauerwerk bzw. den Futtersteinen und der Nut, als auch der frontseitigen Fläche des Flansches und dem Wulst steht.This object is achieved with a chimney connection of the type mentioned above in that the chimney flange of the compensator has a circumferential bead protruding from its front surface, that in the flat surface of the chimney part while maintaining a distance from the inlet, a circumferential, essentially complementary to the bead Shaped groove is formed and that the flange is only directly against the masonry or the lining stones by an interposed layer of rubber-elastic material and is pressed by radially outside the flange, held in the masonry or the lining stones screw connections, as well as clamping parts, which the area of Cover the bulge, the bulge protruding into the groove and the layer being adhesively bonded both to the masonry or the casing stones and the groove, and to the front surface of the flange and the bulge.

Mit einer solchen Ausbildung lassen sich Leckstellen auch ohne Anwendung großer Anpreßkräfte zuverlässig vermeiden und es tritt darüber hinaus eine wesentliche Kosteneinsparung auf, weil komplizierte Anschlußrahmen am Kamin selbst entbehrlich werden und alle Metallteile außerhalb des Rauchgasstromes liegen und damit aus weniger aufwendigem Material gefertigt werden können. Beispielsweise genügt es, die Klemmteile (Klemmleisten bzw. Spannpratzen u. ggf. Druckstücke) aus handelsüblichem Baustahl zu fertigen und mit einer gummielastischen korrosionshindernden Schutzhaut auszustatten.With such a design, leaks can be reliably avoided even without the application of large contact forces, and there is also a significant cost saving because complicated connection frames on the chimney itself can be dispensed with and all metal parts lie outside the flue gas stream and can therefore be made from less expensive material. For example, it is sufficient to manufacture the clamping parts (clamping strips or clamping claws and possibly pressure pieces) from commercially available structural steel and to equip them with a rubber-elastic, corrosion-preventing protective skin.

Weitere Merkmale und Vorteile ergeben sich aus den Unteransprüchen.Further features and advantages result from the subclaims.

Der anzuschließende Kamin weist einen seitlichen Einlaß 1 auf, welcher mit säurebeständigen Futtersteinen 2 ausgekleidet ist. Die Futtersteine 2 erstrecken sich auch noch über den den Einlaß 1 umgebenden Kaminteil und bilden dort eine im wesentlichen ebene Fläche 3. Aus dieser ist durch Fräsen oder Schleifen eine den Einlaß 1 in Abstand von mehreren Zentimetern umgebende, in sich geschlossene Nut 4 herausgearbeitet. Vorteilhaft wird die Nut 4 durch Verwendung bereits entsprechend geformter Futtersteine 2 bereitgestellt, wie dies an späterer Stelle anhand der Fig. 6 und 7 näher erläutert wird.The fireplace to be connected has a side inlet 1, which is lined with acid-resistant stones 2. The lining stones 2 also extend over the chimney part surrounding the inlet 1 and form an essentially flat surface 3. From this, a closed groove 4, which surrounds the inlet 1 at a distance of several centimeters, is worked out by milling or grinding. The groove 4 is advantageously provided by using already shaped casing stones 2, as will be explained in more detail later with reference to FIGS. 6 and 7.

An einem den Rauchgasstrom in Richtung des Pfeiles 5 heranführenden Rauchgasrohr 6 ist ein aus gummielastischem Material bestehender Kompensator 7 an seinem einen Ende durch eine an sich bekannte, aus einem Flansch, Klemmleisten und Schraubverbindungen bestehende Anordnung 7' befestigt. Das andere Ende des Kompensators 7 weist einen radial vorstehenden Flansch 8 ebenfalls aus gummielastischem Material auf, von dem ein Wulst 9 in radialem Abstand von mehreren Zentimetern vom inneren Flanschrand einstückig angeformt ist und von der frontseitigen Fläche 10 vorsteht. Die Querschnittsform und Anordnung des Wulstes 9 ist entsprechend der Nut 4 gewählt, d.h. es liegt eine komplementäre Formgebung vor, wobei der Querschnitt des Wulstes gleich oder etwas kleiner als der der Nut 4 sein kann.On a flue gas pipe 6 leading the flue gas flow in the direction of arrow 5, a compensator 7 made of rubber-elastic material is fastened at one end by an arrangement 7 'known per se, consisting of a flange, terminal strips and screw connections. The other end of the compensator 7 has a radially projecting flange 8 also made of rubber-elastic material, from which a bead 9 is integrally formed at a radial distance of several centimeters from the inner flange edge and protrudes from the front surface 10. The cross-sectional shape and arrangement of the bead 9 is selected according to the groove 4, i.e. there is a complementary shape, the cross section of the bead being equal to or slightly smaller than that of the groove 4.

Die frontseitige Fläche 10 des Flansches 8 ist mit der ebenen Fläche 3 der Futtersteine 2 und der Wulst 9 ist mit der Nut 4 über eine Schicht 11 (vergl. Fig. 2 und 3) verklebt, welche aus einem Zweikomponenten-Elastomerkleber besteht, der in nichtvulkanisiertem Zustand als plastische Kautschukmasse aufgetragen wurde und anschließend vernetzt und einen gummielastischen Zustand einnimmt. Die Schicht gleicht gröbere und feinere Unebenheiten der Futtersteine 2 und der in ihr ausgebildeten Nut 4 aus und seine Dicke wird entsprechend den größten vorkommenden Unebenheiten bemessen.The front surface 10 of the flange 8 is glued to the flat surface 3 of the casing stones 2 and the bead 9 is glued to the groove 4 by means of a layer 11 (see FIGS. 2 and 3) which consists of a two-component elastomer adhesive, which in non-vulcanized state was applied as a plastic rubber composition and then crosslinked and assumes a rubber-elastic state. The layer compensates for coarser and finer bumps in the lining stones 2 and the groove 4 formed in them, and its thickness is dimensioned in accordance with the largest bumps that occur.

Der Flansch 8 wird an die ebene Fläche 3 von einer Mehrzahl von Klemmteilen 12 angepreßt. Diese bestehen aus mit geringem Spiel aneinanderstoßenden Klemmleisten 14', welche an der rückwärtigen Seite 13 des Flansches 8 großflächig angreifen und den Wulst 9 einschließlich beidseitig angrenzender Bereiche überdecken. Die Klemmleisten 14'stehen radial nach außen über den Flansch 8 vor und weisen im Bereich ihrer äußeren Enden Druckstücke 14" auf, die annähernd der Dicke des Flansches 8 entsprechen und sich noch an der ebenen Fläche 3 der Futtersteine 2 abstützen. Zwischen dem Außenrand des Flansches 8 und den Druckstücken 14" sind Schraubverbindungen 15 vorgesehen, die jeweils einen am Futterstein 3 verankerten ersten Bestandteil (z. B Stehbolzen) und einen damit über ein Gewinde verbundenen, eine Druckkraft auf die Klemmleisten 14' bewirkenden zweiten Bestandteil (z. B. Mutter, enthalten. Die Klemmleisten 14' und die Druckstücke 14" bestehen aus handelsüblichem Baustahl und sind vollständig mit einer als dick ausgezogenen Linie in Fig. 2 angedeuteten Schutzschicht 16 aus gummielastischen Material überzogen.The flange 8 is pressed against the flat surface 3 by a plurality of clamping parts 12. These consist of clamping strips 14 'which abut one another with little play, which engage over a large area on the rear side 13 of the flange 8 and cover the bead 9, including regions adjoining on both sides. The clamping strips 14 ′ protrude radially outward beyond the flange 8 and have pressure pieces 14 ″ in the region of their outer ends, which correspond approximately to the thickness of the flange 8 and are still supported on the flat surface 3 of the casing stones 2. Between the outer edge of the The flange 8 and the pressure pieces 14 ″ are provided with screw connections 15, each of which has a first component anchored to the casing 3 (for example a stud bolt) and a second component connected to it via a thread and exerting a pressure force on the terminal strips 14 ′ (for example The clamping strips 14 ′ and the pressure pieces 14 ″ consist of commercially available structural steel and are completely covered with a protective layer 16 of rubber-elastic material indicated as a thick solid line in FIG. 2.

In der Ausführungsform gemäß Fig. 1 weist der Wulst 9 und damit auch die Nut 4 eine dreieckige Querschnitts form auf. Abgeänderte Ausführungsformen gemäß Fig. 2 und 3 besitzen einen Wulst 9' und eine Nut 4' mit trapezförmigen Querschnitt bzw. einen Wulst 9" und eine Nut 4" mit halbrundem Querschnitt.In the embodiment according to FIG. 1, the bead 9 and thus also the groove 4 have a triangular cross-sectional shape. Modified embodiments according to FIGS. 2 and 3 have a bead 9 'and a groove 4' with a trapezoidal cross section or a bead 9 "and a groove 4" with a semicircular cross section.

In den Ausführungsformen gemäß Fig. 4 und 5 weist die Nut 4"' an jeder ihrer beiden Seitenflanken eine Hinterschneidung 4a bzw 4b auf. Der Wulst 9 ''' besitzt seitliche Vorsprünge, welche formschlüssig in diesen Hinterschneidungen 4a bzw 4b gehalten sind. Gemäß der Ausführungsform nach Fig. 5 enthält der Wulst 9'" noch eine sich parallel zu seiner Längsachse erstreckende Hohlkammer 9a, welche seine Einbringung in die Nut 4"' erleichtert.4 and 5, the groove 4 "'has an undercut 4a or 4b on each of its two side flanks.

Bei den beiden letztgenanten Ausführungsformen bestehen die Klemmteile 12 aus mehreren mit geringem Spiel aneinanderstoßenden Flachstäben 17, von denen jeder wiederum durch mehrere Spannpratzen 18 und Schraubverbindungen 15 angepreßt wird. Sowohl die Flachstäbe 17, als auch die Spannpratzen 18 bestehen aus handelsüblichem Baustahl und weisen jeweils eine geschlossene Schutzschicht 16 aus gummielastischem Material auf.In the two last-mentioned embodiments, the clamping parts 12 consist of a plurality of flat bars 17 abutting one another with little play, each of which in turn is pressed by a plurality of clamping claws 18 and screw connections 15. Both the flat bars 17 and the clamping claws 18 consist of commercially available structural steel and each have a closed protective layer 16 made of rubber-elastic material.

Abhängig vom speziellen Einsatzgebiet kann im Fall der Fig. 4 und 5 (Nut mit Hinterschneidung) auch auf die Flachstäbe 17 verzichtet werden und die Anpressung mit den Spannpratzen 18 alleine vorgenommen werden.Depending on the specific area of application, in the case of FIGS. 4 and 5 (groove with undercut), the flat bars 17 can also be dispensed with and the pressing with the clamping claws 18 can be carried out alone.

Die Fig. 6 und 7 erläutern eine spezielle Ausgestaltung, welche eine Reduzierung der Montagezeit und der von den Schraubverbindungen 15 auf die Futtersteine 2 ausgeübten Beanspruchungen erlaubt.6 and 7 explain a special embodiment which allows a reduction in the assembly time and the stresses exerted by the screw connections 15 on the casing stones 2.

Die Futtersteine 2 bilden in ihrer Gesamtheit einen den Einlaß 1 (Fig. 1), des Kamins umgebenden Rahmen und weisen u.a. zwei Fugenflächen 2a auf, an denen benachbarte Futtersteine 2 über Fugen 19 aneinandergrenzen, sowie eine einen Bestandteil der Wandung des Einlasses 1 bildende Seitenfläche 2b, eine einen Bestandteil der den Einlaß 1 umgebenden ebenen Fläche 3 bildenden, zu den Fugenflächen 2a lotrechte Frontfläche 2c und eine dazu Parallele rückseitige Fläche 2d. Die Futtersteine 2 können in der einen Fläche 2a einen rippenartigen Vorsprung und an der anderen Fläche 2a eine komplementär ausgebildete Vertiefung aufweisen und eine im Schnitt parallel zu den Fugenflächen 2a L-förmige Gestalt besitzen.The lining stones 2 in their entirety form a frame surrounding the inlet 1 (FIG. 1) of the chimney and have, inter alia, two joint surfaces 2a, on which adjacent casing stones 2 adjoin one another via joints 19, and a side surface 2b forming part of the wall of the inlet 1, a front surface 2c forming part of the flat surface 3 surrounding the inlet 1 and perpendicular to the joint surfaces 2a and one parallel rear surface 2d. The casing stones 2 can have a rib-like projection in one surface 2a and a complementary recess on the other surface 2a and have an L-shaped shape in section parallel to the joint surfaces 2a.

Jeder Futterstein 2 enthält in seiner Frontfläche 2c und in Abstand von der Seitenfläche 2b einen bereits bei seiner Herstellung vorgesehenen Nutabschnitt 22, der sich von einer der Flächen 2a bis zur anderen Fläche 2a erstreckt. Die Nutabschnitte 22, welche in ihrer Gesamtheit eine den Einlaß 1 umgebende, in sich geschlossene Nut 4 bilden, können auch abweichend von der dargestellten Querschnittsform (entsprechend Fig. 2) eine andere Querschnittsform aufweisen, wie sie in den Fig. 1 und 3 - 5 veranschaulicht ist.Each casing 2 contains in its front surface 2c and at a distance from the side surface 2b a groove section 22 already provided during its manufacture, which extends from one of the surfaces 2a to the other surface 2a. The groove sections 22, which in their entirety form a self-contained groove 4 surrounding the inlet 1, can also have a different cross-sectional shape, as shown in FIGS. 1 and 3-5, deviating from the cross-sectional shape shown (corresponding to FIG. 2) is illustrated.

Die Futtersteine 2 weisen Aussparungen 20 auf, deren Längsachsen 21 lotrecht zu den Frontflächen 2c stehen. Jede Aussparung 20 ist hälftig in Bezug auf die Längsachse 21 in die Fugenfläche 2a dergestalt bereits bei der Herstellung des Futtersteins 2 eingeformt, daß zwei an ihren Fugenflächen 2a aneinanderliegende Futtersteine 2 eine vollständige Aussparung 20 bilden. Jede Aussparung 20 setzt sich aus einem von der Frontfläche 2c ausgehenden tieferen Abschnitt 20 a mit einer (bezogen auf die Längsachse 21) kreisförmigen Querschnittsform und einen sich daran anschließenden, axial flacheren, jedoch radial weiteren zweiten Abschnitt 20 b zusammen. Letzterer hat die Form einer zur rückseitigen Fläche 2d offenen, quaderförmigen Tasche.The lining stones 2 have cutouts 20, the longitudinal axes 21 of which are perpendicular to the front surfaces 2c. Each recess 20 is already half-shaped with respect to the longitudinal axis 21 in the joint surface 2a in such a way during the manufacture of the lining block 2 that two lining stones 2 lying against one another on their joint surfaces 2a form a complete recess 20. Each recess 20 is composed of a deeper section 20 a starting from the front surface 2 c with a circular cross-sectional shape (with respect to the longitudinal axis 21) and an adjoining axially flatter but radially further second section 20 b. The latter has the shape of a cuboid pocket open to the rear surface 2d.

Die Schraubverbindung 15 enthält einen ersten Bestandteil 15a, bestehend aus einem zylindrischen, an einem Ende ein Außengewinde 15"a tragenden Schaft 15'a und einen an dessen anderem Ende befestigten Verankerungsteil 15"'a in Form einer mittig angeschweißten rechteckigen Platte. Der zweite Bestandteil 15b besteht aus einer auf das Gewinde 15"a aufgeschraubten Mutter.The screw connection 15 contains a first component 15a, consisting of a cylindrical shaft 15'a carrying an external thread 15 "a at one end and an anchoring part 15" 'a fastened to the other end in the form of a rectangular plate welded on in the middle. The second component 15b consists of a nut screwed onto the thread 15 "a.

Beim Setzen der Futtersteine 2 werden die ersten Bestandteile 15a der Schraubverbindung 15 so eingelegt, daß die Verankerungsteile 15"'a in den zweiten Abschnitten 20b der Aussparungen 20 liegen und verdrehungssicher gehalten sind, während die ersten Abschnitte 20a mit den Gewinden 15"'a über die Frontflächen 2c vorstehen.When setting the casing stones 2, the first components 15a of the screw connection 15 are inserted in such a way that the anchoring parts 15 "'a lie in the second sections 20b of the recesses 20 and are held against rotation, while the first sections 20a with the threads 15"' a over the front surfaces 2c protrude.

Abhängig von den Baugrößen der Futtersteine 2 und der Ausbildung der Klemmteile 12 können die Aussparungen 20 und/oder die darin angeordneten ersten Bestandteile 15a der Schraubverbindungen 15 auch nur in einem Teil der Futtersteine vorgesehen sein oder es können zu den Fugenflächen 2a nicht offene Aussparungen ausschließlich oder zusätzlich vorgesehen werden.Depending on the sizes of the lining stones 2 and the design of the clamping parts 12, the cutouts 20 and / or the first components 15a of the screw connections 15 arranged therein can also be provided only in part of the lining stones, or recesses that are not open to the joint surfaces 2a can be exclusively or can also be provided.
