Abstract

The present invention relates to a flue-tube for reconstruction of chimneys comprising several tubular sections (1, 2) having conically widening end section (3) and conically narrowing end section (4) with the same angles of taper ratio and that can be connected with each other by inserting the conically narrowing end into the conically widening end. In order to simplify the manufacture of the flue sections (1, 2) and at the same time to achieve exact formation of the cones, these conical end sections (3, 4) follow up with the tubular section (1, 2) body (1a, 2a) at transient external steps (6, 8) and the conically narrowing end (4) is widened by the transient external step (8) with respect to the main body (2a) that its diameter all over its length is at the most equal to the diameter of the tubular section (1, 2) body (1a, 2a).

Description

Die Erfindung betrifft ein Kaminrohr für die Schornsteinsanierung aus mehreren Rohrabschnitten, die jeweils ein konisch erweitertes Ende und ein konisch verjüngtes Ende mit gleichen Konuswinkeln aufweisen und die durch Einstecken des verjüngten Endes in das erweiterte Ende miteinander verbindbar sind.The invention relates to a chimney pipe for chimney renovation from several Pipe sections, each with a flared end and a tapered have a tapered end with the same cone angles and through Inserting the tapered end into the expanded end can be connected to one another are.

Bei der Sanierung von Kaminen wird vom oberen Ende des Kamins ein aus mehreren Rohrabschnitten zusammengesetztes Kaminrohr in den Kaminschacht eingebracht und wird gegebenenfalls der Raum zwischen dem eingebrachten Kaminrohr und einem ebenfalls in den Kaminschacht eingebrachten Außenrohr mit Isoliermaterial versehen. Die Steckverbindung zwischen dem konisch erweiterten Ende und dem konisch verjüngten Ende muß einerseits hinreichende Haltekräfte zwischen benachbarten Rohrabschnitten aufbringen und außerdem gas- und kondensatdicht sein.When renovating fireplaces, one starts from the top of the fireplace chimney pipe composed of several pipe sections in the Inserted chimney shaft and the space between the inserted chimney pipe and also in the chimney shaft Provide the outer tube with insulating material. The connector between the flared end and the tapered end on the one hand, there must be sufficient holding forces between neighboring ones Apply pipe sections and also be gas and condensate tight.

Diese Bedingungen erfüllt eine bekannte Ausführung der eingangs beschriebenen Gattung (DE 94 19 304 U), - und zwar bei Konuswinkeln zwischen 0,5° bis 2° und Längen von wenigstens 60 mm der konischen Enden bei Rohrabschnittsdurchmessem von bis zu 1.000 mm. Bei der bekannten Ausführung ist das konisch erweiterte Ende gegenüber dem Durchmesser des Rohrabschnitts aufgeweitet, es besitzt also gegenüber dem Rohrabschnitt größere Durchmesser. Das konisch verjüngte Ende besitzt kleinere Durchmesser als der Rohrabschnitt.These conditions are met by a known version of the one described at the beginning Genus (DE 94 19 304 U), - with cone angles between 0.5 ° to 2 ° and lengths of at least 60 mm of the conical ends for pipe section diameters of up to 1,000 mm. In the known version the conically widened end compared to the diameter of the pipe section expanded, so it has a larger diameter than the pipe section. The tapered end has smaller diameters than the pipe section.

Die Herstellung, insbesondere des verjüngten konischen Endes ist nicht unproblematisch, weil dazu besondere Werkzeuge erforderlich sind. Dennoch wird nicht immer erreicht, daß der Konuswinkel des konisch verjüngten Endes exakt dem Konuswinkel des konisch erweiterten Endes entspricht, so daß es zu Störungen bei der Montage und auch während des Betriebes kommen kann. The manufacture, especially the tapered conical end, is not without problems, because special tools are required. Yet is not always achieved that the cone angle of the tapered end corresponds exactly to the cone angle of the flared end, so that it disruptions occur during assembly and also during operation can.

Eine andere bekannte Rohrverbindung (DE 195 19 073 A) ist leicht lösbar und weist Rohrabschnitte mit jeweils einem zylindrischen, aufgeweiteten Muffenende und einem zylindrischen, aufgeweiteten Einsteckende auf, zwischen denen ein Dichtungsring angeordnet ist. Das Muffenende weist einen konischen Übergangsbereich zum Rohrabschnitt auf, in den ein am freien Ende des Einsteckendes vorgesehener Konus eingreift. Die Konuswinkel sind so groß, daß keine selbsthemmende Rohrverbindung entstehen kann.Another known pipe connection (DE 195 19 073 A) is easily detachable and has pipe sections each with a cylindrical, expanded Sleeve end and a cylindrical, widened insertion end, between which a sealing ring is arranged. The socket end has one conical transition area to the pipe section, in the one at the free The cone provided at the end of the insertion end engages. The cone angles are so large that no self-locking pipe connection can occur.

Aufgabe der Erfindung ist es, die Herstellung der Rohrabschnitte zu vereinfachen und dabei eine exakte Ausbildung der Konen zu erreichen.The object of the invention is to simplify the manufacture of the pipe sections and to achieve an exact formation of the cones.

Diese Aufgabe wird gelöst, mit einem Kaminrohr nach Patentanspruch 1. Dann können sowohl das konisch erweiterte Ende als auch das konisch verjüngte Ende praktisch mit gleichen Werkzeugen hergestellt werden. Weil das Aufweiten eines Rohrendes mit größerer Präzision erfolgen kann, ist sichergestellt, daß die Konuswinkel der beiden Enden identisch sind. Damit erreicht man eine einfache Montage, denn die Rohrabschnitte zentrieren sich beim Einstecken selbst. Wegen der kleinen Konuswinkel entsteht eine selbsthemmende Steckverbindung mit hinreichenden Haltekräften, die auch ohne Einsatz zusätzlicher Dichtungsmittel gas- und kondensatdicht ist.This object is achieved with a chimney pipe according to claim 1. Then both the flared end and the flared end can tapered ends can be made with virtually the same tools. Because the widening of a pipe end can be done with greater precision ensures that the cone angles of the two ends are identical. In order to easy assembly is achieved because the pipe sections are centered when inserting itself. Because of the small cone angle there is a self-locking connector with sufficient holding force, which too is gas and condensate-tight without the use of additional sealants.

Insbesondere kann die Wandung des Rohrabschnittes im Übergangsbereich zum konisch verjüngten Ende eine nach außen gerichtete Stufe mit runden Kanten aufweisen. Im übrigen genügt es, wenn der Durchmesser der stimseitigen Öffnung des konisch verjüngten Endes gleich dem Durchmesser des Rohrabschnittes ist. Dann kann vorzugsweise die Wandung des Rohrabschnittes im Übergangsbereich zum konisch erweiterten Ende eine nach außen gerichtete Stufe mit runden Kanten aufweisen.In particular, the wall of the pipe section in the transition area to the conical tapered end an outward step with round Have edges. Otherwise, it is sufficient if the diameter of the frontal opening of the tapered end equal to the diameter of the pipe section. Then the wall of the Pipe section in the transition area to the flared end one have an outward step with rounded edges.

Bei einer bevorzugten Ausführung weist das konisch erweiterte Ende im Überdeckungsbereich mit einem eingesteckten konisch verjüngten Ende eine nach außen gerichtete umlaufende Sicke auf. Diese Sicke dient als Kapillarsperre bzw. als Feuchtigkeitssammler für Kondensate, die dann nicht bis zu dem das Kaminrohr umgebenden Isoliermaterial vordringen können. In a preferred embodiment, the flared end faces in the overlap area with an inserted conical tapered end one after peripheral bead on the outside. This bead serves as a capillary barrier or as a moisture collector for condensate, which is not up to that Insulation material can penetrate the chimney pipe.

Vorzugsweise wird der Rohrabschnitt aus einem Blechstreifen gebildet, dessen Stoßkanten miteinander verschweißt sind. Bevorzugt ist eine Ausführung, bei der der Rohrabschnitt eine sich in axialer Richtung erstreckende Längsschweißnaht aufweist.Preferably, the pipe section is formed from a sheet metal strip, the Butt edges are welded together. An embodiment in which the pipe section has a longitudinal weld seam extending in the axial direction having.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert. Die einzige Figur zeigt teilweise einen Längsschnitt durch ein Kaminrohr für die Schornsteinsanierung.In the following an embodiment shown in the drawing Invention explained.

Die Rohrabschnitte 1, 2 bestehen aus Edelstahl und sind aus einem Blechstreifen gebildet, der zu einem Rohrabschnitt geformt worden ist, wobei seine Stoßkante mit einer sich in axialer Richtung erstreckenden Längsschweißnaht verschweißt ist. Das ist im einzelnen nicht dargestellt.The chimney pipe shown in the drawing for chimney renovation consists of several, connected by plug-in connection Pipe sections, of which only two pipe sections 1, 2 are shown. The pipe sections 1, 2 are made of stainless steel and are made of one Formed sheet metal strip, which has been formed into a tube section, wherein its abutting edge with an extending in the axial direction Longitudinal weld is welded. This is not shown in detail.

Jeder Rohrabschnitt 1 bzw. 2 weist ein konisch erweitertes Ende 3 und ein konisch verjüngtes Ende 4 auf. Die Konuswinkel der Konen sind jeweils identisch und betragen ca. 0,5° bis 2°. Die Länge der konischen Enden 3, 4 bzw. ihr Überdeckungsgrad bei ineinandergesteckten Enden 3, 4 beträgt bei Rohrabschnittsdurchmessern von bis zu 1.000 mm wenigstens 60 mm.Each pipe section 1 or 2 has a flared end 3 and tapered end 4. The cone angles of the cones are identical and are approximately 0.5 ° to 2 °. The length of the conical ends 3, 4 or their degree of overlap with nested ends 3, 4 is for pipe section diameters of up to 1,000 mm at least 60 mm.

Wie man der Zeichnung entnimmt, ist das konisch erweiterte Ende 3 gegenüber dem Rohrabschnitt 1 bzw. 2 aufgeweitet. Seine Durchmesser sind größer als der Durchmesser der Rohrabschnitte 1 bzw. 2.As can be seen from the drawing, the flared end is 3 widened relative to pipe section 1 or 2. Its diameters are larger than the diameter of the pipe sections 1 or 2.

Auch das konisch verjüngte Ende 4 ist gegenüber den Rohrabschnitten 1 bzw. 2 aufgeweitet und besitzt über seine Länge größere Durchmesser als die Rohrabschnitte 1 bzw. 2. Der Durchmesser der stirnseitigen Öffnung 5 des konisch verjüngten Endes 4 ist bei der dargestellten Ausführung gleich dem Durchmesser des Rohrabschnittes 1 bzw. 2. The conically tapered end 4 is also opposite the pipe sections 1 and 2 expanded and has a larger diameter than that over its length Pipe sections 1 and 2. The diameter of the front opening 5 of the conically tapered end 4 is the same in the embodiment shown Diameter of the pipe section 1 or 2.

Die Wandung des Rohrabschnittes 1 bzw. 2 im Übergangsbereich zum konisch erweiterten Ende 3 weist eine nach außen gerichtete Stufe 6 mit runden Kanten auf.The wall of the pipe section 1 or 2 in the transition area to the conical widened end 3 has an outward step 6 with rounded edges on.

Ferner weist die Wandung des Rohrabschnittes 1 bzw. 2 im Übergangsbereich zum konisch verjüngten Ende 4 ebenfalls eine nach außen gerichtete Stufe 8 mit runden Kanten auf. Diese Stufe 8 entsteht beim Aufweiten des konisch verjüngten Endes 4 über den Durchmesser des Rohrabschnittes 1 bzw. 2.Furthermore, the wall of the pipe section 1 or 2 has in the transition area to the conically tapered end 4 also an outward step 8 with rounded edges. This stage 8 arises when the conical flare tapered end 4 over the diameter of the pipe section 1 or 2.

In der Zeichnung ist noch dargestellt, daß das konisch erweiterte Ende 3 im Überdeckungsbereich mit einem eingesteckten konisch verjüngten Ende 4 eine nach außen gerichtete umlaufende Sicke 9 aufweist, die als Kapillarsperre bzw. als Feuchtigkeitssammler dient und verhindert, daß Kondensate in eine nicht dargestellte, das Kaminrohr umgebende Isolierung eindringt.In the drawing it is shown that the flared end 3 in Coverage area with an inserted conically tapered end 4 a has outward-facing peripheral bead 9, which acts as a capillary barrier or serves as a moisture collector and prevents condensates from entering insulation, not shown, penetrates the chimney pipe.
