Abstract
Description
Die Erfindung betrifft einen Rohrstrang mit abwechselnd angeordneten glatten Rohrabschnitten und Wellrohrabschnitten, welch letztere jeweils eine Wandung aus mehreren radial auskragenden ringartigen Wellen aufweisen.The The invention relates to a pipe string with alternately arranged smooth pipe sections and corrugated pipe sections, which latter one wall each of a plurality of radially projecting annular Have waves.
Ein
derartiger Rohrstrang ist in der
In Kenntnis dieses Standes der Technik hat sich der Erfinder das Ziel gesetzt, Handwerkern insbesondere für die Herstellung von Abgasleitungen und Kaminen ein Halbzeug anhand zu geben, welches auf einfache Weise gehandhabt und eingebaut zu werden vermag, ohne dass wesentliche Rohrabschnitte zu Abfall werden. Zudem soll es flexibel und dennoch stabil sein.In Knowing this state of the art, the inventor has the goal set, craftsmen in particular for the production of exhaust pipes and Chimneys to give a semifinished product, which in a simple way can be handled and installed without being essential Pipe sections become waste. In addition, it should be flexible and yet be stable.
Zur Lösung dieser Aufgabe führt die Lehre des unabhängigen Anspruches; die Unteransprüche geben günstige Weiterbildungen an. Zudem fallen in den Rahmen der Erfindung alle Kombinationen aus zumindest zwei der in der Beschreibung, der Zeichnung und/oder den Ansprüchen offenbarten Merkmale. Bei angegebenen Benennungsbereichen sollen auch innerhalb der genannten Grenzen liegende Werte als Grenzwerte offenbart und beliebig einsetzbar sein.to solution performs this task the teaching of the independent claim; to give the dependent claims favorable Further education. In addition, all fall within the scope of the invention Combinations of at least two in the description, the drawing and / or the claims disclosed features. For specified naming ranges should also Values within limits are disclosed as limits and be used as desired.
Erfindungsgemäß umfängt der Rohrstrang als Außenrohr mit abwechselnden glatten Rohrabschnitten und Wellrohrabschnitten konstanten Innendurchmessers ein koaxiales, durchgehend glattes Innenrohr. Zudem soll sich die Außenfläche des glatten Innenrohres an die Innenfläche der zylindrischen Rohrabschnitte des Außenrohres anschmiegen.According to the invention Pipe strand as outer tube with alternating smooth pipe sections and corrugated pipe sections constant inside diameter a coaxial, continuous smooth Inner tube. In addition, the outer surface of the smooth inner tube should to the inner surface Cling to the cylindrical tube sections of the outer tube.
Von besonderer Bedeutung zur Lösung der zugrundeliegenden Aufgabe ist, dass das Innenrohr aus weichem Kunststoff geformt und vom Außenrohr härteren Werkstoffes umfangen wird; hierdurch wird ein optimales Anschmiegen benachbarter Flächen ermöglicht.From particular importance to the solution The underlying task is that the inner tube of soft Plastic molded and from the outer tube harder material is embraced; This is an optimal nestling adjacent Areas possible.
Nach einem weiteren Merkmal der Erfindung weist die ringförmige Welle des Wellrohrabschnittes querschnittlich zwei in einem Winkel zueinander geneigte Seitenwände auf, die radial nach außen in einem Teilkreisbogen als Scheitelbereich der Welle übergehen; jener Winkel soll bevorzugt etwa 18° bis 22° messen. Hierdurch wird es möglich, dass die beiden Seitenwände der Welle einen sich von der Rohrlängsachse weg konisch verjüngenden Welleninnenraum begrenzen.To Another feature of the invention comprises the annular shaft the corrugated pipe section cross-sectionally two at an angle to each other inclined side walls on, the radially outward go over in a partial arc as the apex area of the shaft; that angle should preferably measure about 18 ° to 22 °. This makes it possible that the two side walls the shaft is tapered away from the tube longitudinal axis conically Limit wave interior.
Es liegt im Rahmen der Erfindung, dass zumindest eine der Seitenwände der Welle zur Rohrlängsachse hin in einen querschnittlich teilkreisförmigen Fußbereich oder Wellengrund übergeht, welcher der Außenfläche des Innenrohres angelegt wird. Die Mittelpunkte achsparallel benachbarter Fußbereiche sollen in einem Abstand von bevorzugt 7 mm bis 8 mm angeordnet sein und der axiale Mittelabstand der beiden endwärtigen Wellen des Wellrohrabschnitts soll etwa 120 mm bis 130 mm betragen bei einem konstanten Innendurchmesser des Außenrohres von etwa 79 mm bis 80 mm.It is within the scope of the invention that at least one of the side walls of the Shaft to the pipe axis into a cross-sectionally part-circular foot area or wave bottom, which of the outer surface of the Inner tube is created. The centers parallel to the axis adjacent Foot areas should be arranged at a distance of preferably 7 mm to 8 mm and the axial center distance of the two endwärtigen waves of the corrugated pipe section should about 120 mm to 130 mm at a constant inner diameter of the outer tube from about 79 mm to 80 mm.
Um eine höhere Stabilität des Systems zu erreichen, hat es sich als günstig erwiesen, die Wellenwände mit Radialrippen abzustützen, welche in dem Welleninnenraum von der zylindrischen Außenfläche des Innenrohres ausgehen; diese Radialrippen enden am Übergang vom äußeren Teilkreisbogen in die Seitenwand an dieser und stützen sie ab.Around a higher one stability To achieve the system, it has proven to be beneficial to the shaft walls with Support radial ribs, which in the shaft interior of the cylindrical outer surface of the Inner tube go out; These radial ribs end at the transition from the outer partial arc in the sidewall at this and support it.
