Description

Durch Stege zusammengefaßtes, biegsames Rohrbündel aus Kunststoff Die Erfindung betrifft ein durch Stege zusammengefaßtes, biegsames Rohrbündel aus Kunststoff, das vorzugsweise in Druckübertragungsanlagen Anwendung finden soll. Als Baustoff für die Rohre dient Kunststoff, wie z. B. Polyäthylen. Sie können gegebenenfalls noch mit Kunststoff, vorzugsweise Polyvinylchlorid, unimantelt sein. Erfahrungsgemäß lassen sich Rohrbündel nur mit einem verhältnismäßig großen Krümmungsradius biegen, der vom Rohrdurchmesser abhängt und um so größer sein muß, je mehr Rohre im Bündel vereinigt sind.Flexible plastic tube bundle combined by webs. The invention relates to a flexible plastic tube bundle which is combined by webs and is preferably used in pressure transmission systems. Plastic is used as the building material for the pipes, e.g. B. polyethylene. They can optionally also be coated with plastic, preferably polyvinyl chloride. Experience has shown that tube bundles can only be bent with a relatively large radius of curvature, which depends on the tube diameter and must be larger, the more tubes are combined in the bundle.

Es ist bekannt, Einzelrohre in einer Ebene liegend durch je einen Steg miteinander zu verbinden. Ein solches Rohrsystem kann jedoch nur senkrecht zur Verbindungsebene gebogen werden, während in allen anderen Richtungen beim Biegen Schwierigkeiten auftreten, Aufgabe der Erfindung ist es, mehrere Rohre zu einem Bündel zu vereinigen, das in beliebiger Richtung gebogen bzw. verforint werden kann. Erreicht ist dies dadurch, daß die die Einzelrohre haltenden Stege sternfönnig zu einem massiven Mittelstrang angeordnet und so lang und so nachgiebig ausgeführt sind, daß sich die Einzelrohre beim Biegen des Rohrbündels längs einer senkrecht zur Biegerichtung liegenden Geraden nebeneinanderlegen können.It is known to connect individual tubes lying in one plane with each other by means of a web. However, such a pipe system can only be bent perpendicular to the connecting plane, while difficulties arise in all other directions when bending. The object of the invention is to combine several pipes into a bundle that can be bent or deformed in any direction. This is achieved in that the webs holding the individual tubes are arranged in a star shape to form a solid central strand and are so long and flexible that the individual tubes can lie next to each other when the tube bundle is bent along a straight line perpendicular to the bending direction.

Die Zeichnung veranschaulicht Ausführungsbeispiele des erfindungsgemäßen Rohrbündels im Querschnitt. Es zeigt A b b. 1 ein Rohrbündel aus Kunststoffrohren, A b b. 2 ein Rohrbündel mit kunststoffummantelten Rohren, und Ab b. 3 läßt die Anordnung der Rohre bei gebogenem Rohrbündel erkennen.The drawing illustrates exemplary embodiments of the tube bundle according to the invention in cross section. It shows A b b. 1 a tube bundle made of plastic tubes, A b b. 2 a tube bundle with plastic-coated tubes, and Ab b. 3 shows the arrangement of the tubes when the tube bundle is bent.

Gemäß Ab b. 1 sind Kunststoffrohre 1 durch Stege 3, die zu einem Mittelstrang 4 führen, verbunden. Bei der Anordnung nach Abb. 2 sind die Rohre 1 von Kunststoffummantelungen 2 umgeben, welche durch die Stege 3 mit dem Mittelstrang 4 verbunden sind.According to Ab b. 1 , plastic pipes 1 are connected by webs 3 which lead to a central strand 4. In the arrangement according to FIG. 2, the tubes 1 are surrounded by plastic jackets 2, which are connected to the central strand 4 by the webs 3.

Die Rohre werden beim Biegen Mes Rohrbündels in ihrer gegenseitigen Beweglichkeit durch die Stege 3 nur wenig behindert. Sie können sich deshalb im Sinne des geringsten Biegemomentes auf einer Geraden A-B, entsprechend der Darstellung der Ab b. 3, nebeneinanderlegen, so daß sich eine gleichmäßige Biegung aller Rohre des Bündels ergibt. Die jeweils zu den einzelnen Rohren führenden nachgiebigen Stege 3 werden dabei verbogen und schachteln sich etwa in der dargestellten Lage ineinander. Bei der in den Ab b. 1 und 2 gezeigten Ausführungsforin des Rohrbündels erfolgt die Einordnung der Rohre auf einer Geraden am einfachsten, wenn das Bündel senkrecht zu einer durch die Stege 3 bestimmten Ebene gebogen wird. Beim Biegen senkrecht zu zwischen den Stegen liegenden Ebenen erfolgt eine gewisse Verwindung des Rohrbündels, so daß auch hier die in Ab b. 3 dargestellte Endlage erreicht wird.When the tube bundle is bent, the mutual mobility of the tubes is only slightly hindered by the webs 3. You can therefore in the sense of the lowest bending moment on a straight line AB, as shown in Ab b. 3, side by side so that all tubes in the bundle are bent evenly. The flexible webs 3 leading to the individual tubes are bent in the process and nestle one inside the other approximately in the position shown. In the case of the abb. 1 and 2, the arrangement of the tubes on a straight line is easiest when the bundle is bent perpendicular to a plane defined by the webs 3. When bending perpendicular to the planes lying between the webs, there is a certain twisting of the tube bundle, so that here too the in Ab b. 3 shown end position is reached.
