Abstract

The chimney flue (3) is of circular cross-section and is made in sections fitted together (12) at the level of each floor (9). Distance pieces (13) support the flue sections and hold them in a central position in the circular cross-section air duct (5) of the chimney (1). The air duct is made in sections, and is surrounded by heat insulation material (4) inside a square-section outer casing (6). The passage through each floor (7) is large enough to leave an air gap which is filled at the top by spacer elements (10,11). External plates (8) overlap the joints between the outer casings. There are metal plates (16) holding fireproof plates (14) at the joints.

Description

Die Erfindung bezieht sich auf einen hinterlüfteten Kamin, der wenigsten eine Geschoßdecke in einer Durchführung durchsetzt, aus einzelnen Längsabschnitten zusammengesetzt ist und aus einem Abgasrohr und einem das Abgasrohr mit radialem Abstand umschließenden Mantel mit einer Wärmedämmung zwischen einem Innenrohr und einer Außenwand besteht.The invention relates to a ventilated fireplace, which interspersed at least one floor slab in a passage, is composed of individual longitudinal sections and consists of an exhaust pipe and the exhaust pipe with a radial distance enclosing jacket with a thermal insulation between an inner tube and an outer wall.

Um das Errichten eines hinterlüfteten Kamins zu vereinfachen, der wenigsten eine Geschoßdecke in einer Durchführung durchsetzt und der sich aus einzelnen Längsabschnitten zusammensetzt, ist es bekannt die Längsabschnitte über jeweils einen Flansch am Abgasrohr miteinander zu verbinden, so daß im Gegensatz zu herkömmlichen Kaminen (DE 9308578 U) der Kamin nicht vermauert und anschließend verputzt werden muß. Von Nachteil bei derartigen Kaminen ist aber, daß eventuelle Seitenkräfte auf den Kamin von den jeweiligen Flanschen aufzunehmen sind, so daß für ein rauchgasdichtes Verbinden der Längsabschnitte vom Abgasrohr eine hohe Festigkeit gefordert wird. Neben dem Abgasrohr unterliegen auch die Mäntel der Längsabschnitte einer vergleichsweise hohen Belastung, da auf diesen jeweils ihre darüberliegenden Längsabschnitte mit deren Gewicht lasten. Daher sind derartige Längsabschnitte vergleichsweise schwer und insbesondere dann von hohem Gewicht, wenn der Kamin mehrere Geschoßdecken durchsetzt. Hinzu kommt, daß eine kostengünstige Serienfertigung der Längsabschnitte nur schwer möglich ist, da deren Festigkeit und damit auch deren jeweilige konstruktive Ausgestaltung von der Kaminhöhe abhängt.In order to simplify the construction of a ventilated fireplace, the least penetrates a floor slab in a passage and composed of individual longitudinal sections, it is known to connect the longitudinal sections via a respective flange on the exhaust pipe together, so that in contrast to conventional fireplaces (DE 9308578 U) the fireplace does not walled and must then be plastered. A disadvantage of such fireplaces is that any lateral forces are to be absorbed by the respective flanges on the chimney, so that a high strength is required for a smoke gas-tight connection of the longitudinal sections of the exhaust pipe. In addition to the exhaust pipe, the coats of the longitudinal sections are subject to a comparatively high load, since their respective longitudinal sections are loaded with their weight on them. Therefore, such longitudinal sections are relatively heavy and especially of high weight when the fireplace passes through several floor slabs. In addition, a cost-effective mass production of the longitudinal sections is difficult, since their strength and thus their respective structural design depends on the chimney height.

Außerdem ist es vorteilhaft, den Mantel der Kamine für einzügige Kamine quadratisch und für mehrere Züge rechteckig auszubilden, da sich das positv auf die gestalterische Einbindung des Kamins im Wohnraumraum und die Anschlüsse an das Mauerwerk auswirkt. US 4 608 963 als auch US 3 087 408 und US 4 502 370 wählen jeweils runde Außenmäntel. Mehrzügige Kamine müssen daher wieder mit einem im Grundriß rechteckigen Schacht umgeben werden was zusätzliche Kosten mit sich bringt.Moreover, it is advantageous to form the coat of fireplaces for single-fire and square for several trains rectangular, as the positive effect on the design integration of the fireplace in the living room and the connections to the masonry effect. US 4,608,963 as well as US 3,087,408 and US 4,502,370 each select round outer shells. Mehrzügige chimneys must therefore be surrounded again with a rectangular in plan floor shaft which brings additional costs.

Da ein Kamin nicht nur als Bauelement von innen nach außen einen Brand zu verhindern hat, sondern auch einen Brand von einem Geschoß in das nächste durch Wärmeleitung des Außenmantels übertragen kann, ist es sinnvoll den Außenmantel in den Geschoßdecken durch eine hitzefeste und thermisch schlecht leitende Trennschicht zu unterbrechen. In EP 0 862 020 A2 wird zwar der Außenmantel des Kamins unterbrochen eine thermische Trennung auf das nächste Geschoß ist jedoch nicht vorhanden, weiters werden in den bereits zuvor zitierten Schriften US 4 608 963, US 3 087 408 und US 4 502 370 die Außenmäntel ohne thermische Trennung und Stoß durch die. Geschoßdecke geführt, was im Brandfalle die ungehinderte Wärmeleitung von einem Geschoß in das nächste ermöglicht und damit ein Weiterleiten eines Brandes ermöglicht.Since a fireplace not only has to prevent a fire from inside to outside as a component, but can also transmit a fire from one floor to the next by heat conduction of the outer shell, it makes sense the outer shell in the storey ceilings by a heat-resistant and thermally poorly conductive separation layer to interrupt. In EP 0 862 020 A2, although the outer shell of the chimney is interrupted, a thermal separation to the next floor is not present, furthermore, in the already cited documents US Pat. No. 4,608,963, US Pat. No. 3,087,408 and US Pat. No. 4,502,370, the outer shells are without thermal break and push through the. Floor ceiling out, which allows in case of fire, the unhindered heat conduction from one floor to the next, thus allowing a forwarding of a fire.

Der Erfindung liegt somit die Aufgabe zugrunde, einen hinterlüfteten Kamin der eingangs geschilderten Art so zu verbessern, daß die Anforderungen an die Festigkeit der Längsabschnitte unabhängig von der Kaminhöhe sind, sowie daß sich die Längsabschnitte durch ihr geringes Gewicht auszeichnen. Die Erfindung löst die gestellt Aufgabe dadurch, daß die Stöße der miteinander zugfest verbundenen Längsabschnitte im Bereich der Geschoßdurchführungen liegen, eine thermische Trennung aufweisen und daß die miteinander verbundenen Längsabschnitte wenigstens an einer Geschoßdecke aufgehängt sind.The invention is therefore an object of the invention to improve a ventilated fireplace of the type described so that the requirements for the strength of the longitudinal sections are independent of the chimney height, and that the longitudinal sections are characterized by their low weight. The invention solves the problem posed by the fact that the joints of the tensile sections connected longitudinal sections are in the range of bullet holes, have a thermal break and that the interconnected longitudinal sections are suspended at least on a floor slab.

Werden die miteinander zugfest verbundenen Längsabschnitte wenigstens an einer Geschoßdecke aufgehängt, so wird zumindest ein Teil des Kamingewichts auf die Geschoßdecke selbst übertragen, wodurch die unterhalb der Aufhängung liegenden Längsabschnitte eine Gewichtsentlastung erfahren. Daher muß auch im Gegensatz zum Stand der Technik die Festigkeit der Längsabschnitte nicht nach der Kaminhöhe ausgelegt werden, so daß vorteilhaft kostengünstige Werkstoffe einsetzbar sind. Insbesondere aber kann damit Gewicht gespart werden, beispielsweise durch den Einsatz von leichten, jedoch gering belastbaren Aluminiumwerkstoffen, wodurch trotz einer geschoßhohen Ausführung besonders einfach die Längsabschnitte aufeinander gesetzt werden können. Sind die Stöße der Längsabschnitte im Bereich der Geschoßdurchführung angeordnet, so lasten auch eventuelle Seitenkräfte nicht auf den jeweiligen Flanschen der Abgasrohre, sondern können von der Geschoßdecke aufgenommen werden. Des weiteren sind auch im Stoßbereich keine besonderen Maßnahmen für ein optisches Verdecken der Stöße erforderlich.If the longitudinal sections connected to one another in a tension-resistant manner are suspended on at least one floor slab, then at least part of the fireplace weight is transmitted to the floor slab itself, as a result of which the longitudinal sections located below the suspension experience weight reduction. Therefore must also in contrast to the prior art, the strength of the longitudinal sections are not designed according to the chimney height, so that advantageously inexpensive materials can be used. In particular, however, so weight can be saved, for example, by the use of lightweight, but low-strength aluminum materials, which in spite of a high-floor design particularly easy longitudinal sections can be placed on each other. If the joints of the longitudinal sections are arranged in the region of the projectile passage, then any lateral forces do not load on the respective flanges of the exhaust pipes, but can be absorbed by the floor slab. Furthermore, no special measures for optical concealment of the shocks are required in the joint area.

Da nicht nur am Abgasrohr Wärmedehnungen in Längsrichtung des Kamins auftreten, sondern, wenngleich auch in einem geringeren Maße, auch am Mantel entstehen, können diese mit einer gegenüber der Geschoßdecke beweglichen Aufhängung abgetragen werden.Since not only the exhaust pipe thermal expansions occur in the longitudinal direction of the fireplace, but, although to a lesser extent, also arise on the jacket, they can be removed with a movable relative to the floor ceiling suspension.

Weisen die Stöße jeweils zumindest eine brandhemmende Abdeckplatte auf, in der für das Abgasrohr und das Innenrohr Öffnungen vorgesehen sind, so kann ein Übergreifen eines Brandes in einem Geschoß von einem Längsabschnitt auf den Nächsten im nächsten Geschoß verhindert werden. Besteht die Abdeckplatte auch aus einem verformbaren Material, so kann mit einer über die zugfest verbundenen Längsabschnitte erzeugten Vorspannung ein dichter Abschluß der Stöße gewährleistet werden, ohne daß enge Fertigungstoleranzen für die Stöße der Längsabschnitte bestehen.If the joints each have at least one fire-retardant cover plate in which openings are provided for the exhaust pipe and the inner pipe, fire spreading in a projectile from one longitudinal section to the next in the next projectile can be prevented. If the cover plate also consists of a deformable material, a tight termination of the shocks can be ensured with a preload generated by the tension-connected longitudinal sections, without there being close manufacturing tolerances for the joints of the longitudinal sections.

Wird im Kamin zumindest ein von der Mantsteinaußenseite ausgehendes und mit dem Innenrohr verbundenes Lüftungsrohr vorgesehen, so eröffnet sich die Möglichkeit, die im Lüftungsrohr geführte und erwärmte Luft zur Geschoßheizung zu verwenden, wobei jedoch zur Brandabschottung des Lüftungsrohres gegenüber dem nächsten Geschoß eine Brandschutzklappe vorgesehen werden kann.If at least one outgoing from the mantle outside and connected to the inner tube ventilation pipe provided in the chimney, so it opens up the possibility of using the guided in the ventilation pipe and heated air for projectile heating, however, for fire partitioning of the ventilation pipe relative to the next floor a fire damper can be provided ,

Der hinterlüftete Kamin (1) setzt sich aus einzelnen Längsabschnitten (2) zusammen und weist in seiner Mitte ein Abgasrohr (3) und ein das Abgasrohr (3) mit radialem Abstand umschließenden Mantel auf, der aus einer Wärmedämmung (4) zwischen einem Innenrohr (5) und einer geraden Außenwand (6) besteht (Fig.1, Fig.3 und Fig.4.) Beispielsweise kann für das Abgasrohr (3) ein Edelstahlrohr, für das Innenrohr (5) ein Aluminiumrohr, für die Wärmedämmung (4) Perlite verwendet werden, sowie kann die Außenwand (6) beispielsweise aus verzinktem Stahl oder Aluminium Blech bestehen die auf der Innenseite miteinander verbunden sind, was nicht näher dargestellt ist. Neben dem vorteilhaften Einsatz von Aluminium oder Stahlwerkstoffen für die Längsabschnitte (2) vermindert auch ein mögliches nachträgliches Einbringen der Wärmedämmung (4) das Eigengewicht der jeweiligen Längsabschnitte (2). Dafür weißt die als Abschluß der Längsabschnitte vorgesehene Metallplatte (16) zumindest eine nicht näher dargestellte Öffnung auf, durch die nach dem Aufeinandersetzen des jeweiligen Längsabschnitts (2) der Dämmstoff eingefüllt werden kann. Die Stöße der aufeinandergesetzten Längsabschnitte (2) liegen im Bereich der Geschoßdurchführungen (7), wobei die Längsabschnitte (2) beispielsweise über eine Platte (8) zugfest miteinander verbunden sind, die an der jeweiligen Außenwand (6) mit Nieten befestigt ist. Der hinterlüftete Kamin (1) ist an wenigstens einer Geschoßdecke (9) aufgehängt (Fig.2), und zwar mit einem an der Oberseite der Geschoßdecke (9) aufliegenden Winkel (10), der in eine an der Außenwand (6) des Kamins befestigten Aufnehmung (11) eingeschoben ist. Der Winkel (10) kann entweder frei auf der Geschoßdecke (9) aufliegen, oder, um ein Anheben des einen Endes des Winkels (10) von der Geschoßdecke (9) zu vermeiden, mit einem Bolzen (17) in Auflagerichtung verschiebefest an der Geschoßdecke (9) befestigt sein. Der Winkel (10) weist hierzu ein Gelenk (23) mit einer Schwenkachse quer zur Winkellängsachse auf, damit sowohl geringe Anforderungen an die Bohrungen für die Bolzen (17) bestehen, als auch auf einfache Weise dem Verlauf der Geschoßdecke (9) gefolgt werden kann. Beispielsweise kann der Winkel (10) auch ein Formrohr zum Einschieben in die Aufnehmung (11) aufweisen, was nicht näher dargestellt ist. Zur seitlichen Abstützung des Kamins (1) muß lediglich der in der Aufnehmung eingeschobene Winkel (10) verankert werden, beispielsweise durch Schrauben. Das Abgasrohr (3) steht an einem Ende dem Mantel vor und trägt am anderen Ende eine Muffe (12), in die dann beim Aufeinandersetzen eines anderen Längsabschnitts sein vorstehendes Abgasrohr (3) abgasdicht eingeschoben ist. Da die eingeschobenen Abgasrohre (3) nicht vollständig in die Tiefe der Muffen (12) reichen, können Wärmedehnungen in Längsrichtung der Abgasrohre (3) ohne weiteres aufgenommen werden. Mit quer zur Längsachse der Längsabschnitte (2) liegenden und am Innenrohr (5) drehbar gelagerten Gewindestangen (13) kann die Lage des Abgasrohrs (3) im Kamin (1) eingestellt werden, insbesondere aber erfährt das Abgasrohr (3) durch die an der Muffe (12) anliegende Gewindestange (13) eine in eine Längsrichtung des Abgasrohrs verschiebefeste Abstützung. Das Innenrohr (5) wird von Metallwinkeln (18) an dessen Ende übergriffen und ist mit der Metallplatte (16) fest verbunden, wobei sich zur Vermeidung einer Wärmebrücke zur Außenwand (6) zwischen den Metallwinkeln (18) und Metallplatte (16) eine Wärmeisolation (19) befindet.The ventilated chimney (1) consists of individual longitudinal sections (2) and has in its center an exhaust pipe (3) and a the exhaust pipe (3) with a radial distance enclosing shell, which consists of a thermal insulation (4) between an inner tube ( 5) and a straight outer wall (6) (Fig.1, Fig.3 and Fig. 4). For example, for the exhaust pipe (3) a stainless steel pipe, for the inner tube (5) an aluminum tube, for the thermal insulation (4) Perlite can be used, as well as the outer wall (6), for example, galvanized steel or aluminum sheet are connected to each other on the inside, which is not shown in detail. In addition to the advantageous use of aluminum or steel materials for the longitudinal sections (2) and a possible subsequent introduction of the thermal insulation (4) reduces the weight of the respective longitudinal sections (2). For this purpose, the metal plate (16) provided as the conclusion of the longitudinal sections has at least one opening, not shown in more detail, through which the insulating material can be filled after the covering of the respective longitudinal section (2). The joints of the juxtaposed longitudinal sections (2) are in the region of the projectile bushings (7), wherein the longitudinal sections (2), for example, via a plate (8) are connected to each other tensile strength, which is attached to the respective outer wall (6) with rivets. The ventilated chimney (1) is suspended from at least one floor slab (9) (FIG. 2), with an angle (10) resting on the upper side of the slab ceiling (9) a mounted on the outer wall (6) of the chimney Aufnehmung (11) is inserted. The angle (10) can either rest freely on the floor slab (9), or, in order to avoid raising the one end of the angle (10) of the floor slab (9), with a bolt (17) in the support direction against the floor slab (9) be attached. For this purpose, the angle (10) has a joint (23) with a pivot axis transverse to the longitudinal axis of the angle, so that both the bores for the bolts (17) are low and the course of the floor slab (9) can be followed in a simple manner , For example, the angle (10) may also have a forming tube for insertion into the recess (11), which is not shown in detail. For lateral support of the chimney (1) only the inserted in the recess angle (10) must be anchored, for example by screws. The exhaust pipe (3) protrudes at one end of the jacket and carries at the other end a sleeve (12), in which then when stacking another longitudinal section its projecting exhaust pipe (3) is inserted gas-tight. Since the inserted exhaust pipes (3) do not extend completely into the depth of the sleeves (12), thermal expansion in the longitudinal direction of the exhaust pipes (3) can be easily absorbed. With transverse to the longitudinal axis of the longitudinal sections (2) and on the inner tube (5) rotatably mounted threaded rods (13), the position of the exhaust pipe (3) in the chimney (1) can be adjusted, but in particular experiences the exhaust pipe (3) by at the Sleeve (12) adjacent threaded rod (13) has a displacement in a longitudinal direction of the exhaust pipe fixed support. The inner tube (5) is overlapped by metal angles (18) at its end and is fixedly connected to the metal plate (16), wherein in order to avoid a thermal bridge to the outer wall (6) between the metal angles (18) and metal plate (16) heat insulation (19).

Um die Wärmedehnungen des Mantels in Längsrichtung des Kamins (1) von der Aufhängung abtragen zu können, ist die Aufhängung für die miteinander verbundenen Längsabschnitte (2) in der Längsachse des Kamins (1) gegenüber der Geschoßdecke (9) beweglich. Hierfür sind an der Außenwand (6) des Kamins (1) Aufnehmungen (11) vorgesehen, in die die Winkel (10) mit Spiel lose eingeschoben sind.In order to be able to remove the heat expansions of the jacket in the longitudinal direction of the chimney (1) from the suspension, the suspension for the interconnected longitudinal sections (2) in the longitudinal axis of the chimney (1) relative to the floor slab (9) is movable. For this purpose, on the outer wall (6) of Chimneys (1) recesses (11) provided, in which the angle (10) are loosely inserted with play.

Zwischen den Stößen befindet sich zumindest eine brandhemmende Abdeckplatte (14) Fig.4, die Öffnungen für das Abgasrohr (3) und das Innenrohr (5) aufweist. Damit kann verhindert werden, daß sich ein Brand über die Wärmedämmung (4) oder Wärmeleitung der Außenwand (6) von einem Längsabschnitt zum Nächsten ausbreitet.Between the joints is at least one fire-retardant cover plate (14) Fig.4, the openings for the exhaust pipe (3) and the inner tube (5). This can prevent a fire spreading over the heat insulation (4) or heat conduction of the outer wall (6) from one longitudinal section to the next.

Die zwischen dem Abgasrohr (3) und dem Innenrohr (5) erwärmte Luft kann über zumindest einem Lüftungsrohr (15) für eine Geschoßheizung verwendet werden. Hierfür geht das Lüftungsrohr (15) von der Außenwand (6) aus und verbindet mit dem Innenrohr (5) wobei das Lüftungsrohr (15) vorteilhaft eine nicht näher dargestellte Brandschutzklappe aufweist. Es muß nicht näher darauf hingewiesen werden, daß derartige Lüftungsrohre (15) auch bei herkömmlichen hinterlüfteten Kaminen zur Geschoßheizung verwendet werden können.The air heated between the exhaust pipe (3) and the inner pipe (5) can be used via at least one ventilation pipe (15) for a floor heating. For this purpose, the ventilation pipe (15) from the outer wall (6) and connects to the inner tube (5) wherein the vent pipe (15) advantageously has a fire damper, not shown. It need not be pointed out that such ventilation pipes (15) can be used in conventional ventilated fireplaces for projectile heating.

Auf das dem Dach vorstehende Endes des Kamins (1) ist eine Abeckkappe (20) vorgesehen, die über Abstandhalter (21) mit dem jeweiligen Längsabschnitt lösbar verbunden ist.
