The invention relates to a pipe assembly comprising a number of plastic pipes running parallel to one another. The individual pipes are fastened together by flexible bands. The bands run on one side tangentially over the width of the pipe assembly and are fixedly connected to defined surface regions of the individual pipes. The individual pipes can be fixed one beside the other, at defined mutual spacings, by the bands.

Description

Die Erfindung betrifft einen Rohrverbund aus einer Anzahl parallel zueinander verlaufender Polymer-Rohre, wobei die Einzelrohre durch flexible Bänder zu dem Rohrverbund zusammengefaßt sind.The invention relates to a tube assembly of a number polymer pipes running parallel to each other, the Individual tubes combined by flexible straps to form the tube assembly are.

Ein derartiger Rohrverbund ist durch das DE-GM 82 13 407.3 bekannt geworden. Dort sind die Einzelrohre des Rohrverbundes durch flexible Abstandsstege zu einer Matte vereinigt. Die Flexibilität der Abstandsstege läßt es zu, daß der Rohrverbund aus der waagerechten Erstreckung der Einzelrohre zu einem Rohrbündel zusammengeklappt werden kann. Je nach Länge der Abstandsstege kann dieses Zusammenlegen derart erfolgen, daß die Einzelrohre untereinander in linienförmiger Berührung stehen und trotzdem durch die Abstandsstege aneinander gehaltert sind. Der Nachteil dieses Rohrverbundes liegt in der aufwendigen Fertigung und in der Möglichkeit des Abreißens der Abstandsstege, beispielsweise beim Einziehen dieses zum Rohrbündel zusammengelegten Rohrverbundes in im Erdboden verlegte Kabelschutzrohre.Such a composite pipe is by DE-GM 82 13 407.3 known. There are the single pipes of the Pipe composite through flexible spacers to a mat united. The flexibility of the spacer bars allows that the pipe assembly from the horizontal extension of the Individual tubes can be folded into a tube bundle can. Depending on the length of the spacers, this can be folded take place in such a way that the individual pipes are mutually stand in line-shaped contact and still through the spacers are held together. The disadvantage this composite pipe lies in the complex production and in the possibility of tearing off the spacer bars, for example when pulling this in to form a tube bundle Pipe assembly in cable protection pipes laid in the ground.

Aus dem deutschen Patent 36 06 767 ist ein flexibler, geschlossener Rohrverbund bekannt, der durch mit flexiblen Bändern verbundene Rohre gebildet wird. Auch in diesem Fall liegen die Einzelrohre parallel zueinander im Rohrverbund, wobei die Einzelrohre durch die Bänder im Abstand voneinander verbunden sind. Im Gegensatz zu der durch die flexiblen Abstandsstege zu einer Matte vereinigten Rohre des erstgenannten Standes der Technik ergibt sich dadurch ein Rohrbündel, in dem alle Einzelrohre durch die Abstand haltenden Bänder miteinander verbunden sind. In beiden Fällen wird erreicht, daß die so geschaffenen Rohrverbunde ohne Auflösung des Verbundes getrommelt werden können.From German patent 36 06 767 is known to be a flexible, closed pipe assembly which formed by pipes connected with flexible bands becomes. In this case, too, the individual pipes are parallel to each other in the pipe network, whereby the individual pipes through the bands are connected at a distance from each other. In contrast to the one thanks to the flexible spacers Mat united pipes of the first mentioned state of the Technology results in a tube bundle in which all Individual pipes through the spacing bands together are connected. In both cases it is achieved that  the pipe assemblies created in this way without breaking up the assembly can be drummed.

Der Anmeldung liegt die Aufgabe zugrunde, einen flexiblen Rohrverbund nach Patent 36 06 767 bereitzustellen, bei dem der Aufwand der Verbindung der Einzelrohre auf ein Minimum herabgesetzt ist.The registration is based on the task of being flexible Provide tube assembly according to Patent 36 06 767, at which the effort of connecting the individual pipes a minimum is reduced.

Die gestellte Aufgabe wird gelöst durch einen Rohrverbund mit den kennzeichnenden Merkmalen des Anspruches 1. In den Ansprüchen 2 und 3 sind Ausbildungen des Rohrverbundes nach Anspruch 1 angegeben.The task is solved by a pipe network with the characterizing features of claim 1. In claims 2 and 3 are training of the composite pipe according to claim 1 specified.

Die Herstellung eines solchen Rohrverbundes ist denkbar einfach. Die Einzelrohre können hier mit einfachen Rohrwerkzeugen gefertigt werden. Nach der Fertigung werden sie parallel zueinander im ausgestreckten Zustand gehalten und in definierten Abständen die Verbindungsbänder mit den zugeordneten Oberflächenbereichen der Einzelrohre fest verbunden. Diese feste Verbindung kann beispielsweise durch Schweißen erfolgen, wobei hier das Ultraschall- Schweißen als vorteilhaft erscheint. Die Verbindung kann auch durch Kleben erfolgen.The production of such a tube assembly is conceivable easy. The single pipes can be made with simple pipe tools are manufactured. After manufacturing held parallel to each other in the extended state and the connecting straps at defined intervals with the assigned surface areas of the individual pipes firmly connected. This fixed connection can, for example by welding, here the ultrasonic Welding appears to be beneficial. The connection can also done by gluing.

In einer vorteilhaften Ausführungsform sind die Einzelrohre durch ein spiralig gewickeltes Band zu dem Rohrverbund zusammengefaßt, wobei die Wendel des Bandes in definiertem Abstand voneinander stehen. Auch bei der Verwendung von Einzelbändern gemäß Anspruch 1 ist ein definierter Abstand der Bänder untereinander auf den Oberflächen der nebeneinander angeordneten Einzelrohre zweckmäßig, der in jedem Fall nach den Anforderungen der Weiterbehandlung des Rohrverbundes gewählt werden soll.  In an advantageous embodiment, the individual tubes through a spirally wound band to the pipe assembly summarized, the coil of the tape in a defined Distance from each other. Even when using it of single tapes according to claim 1 is a defined one Spacing between the tapes on the surfaces of the individual pipes arranged next to each other, in any case according to the requirements of further processing of the pipe network should be selected.  

Mit dem erfindungsgemäßen Rohrverbund ist die Möglichkeit geschaffen, die Einzelrohre in beliebiger Vielzahl nebeneinander anzuordnen. Die einseitig tangential über die Breite dieses Rohrverbundes aufgebrachten Verbindungsbänder ermöglichen das Zusammenklappen des Rohrverbundes in Richtung der aufgebrachten Verbindungsbänder. Wird die spiralige Umwicklung der parallel zueinander liegenden Einzelrohre mit definiertem Abstand der Spiralenwendel voneinander gewählt, so kann dieser Rohrverbund in beiden Richtungen zusammengeklappt werden.With the pipe assembly according to the invention, this is possible created, the individual pipes in any number side by side to arrange. The tangential on one side Width of this pipe assembly applied connecting bands allow the pipe assembly to be folded in Direction of the connecting tapes applied. Will the spiral wrapping of the parallel Single tubes with a defined spiral spiral spacing chosen from each other, so this composite pipe in both Directions are folded.

Die Zusammenfassung der Einzelrohre zu dem Rohrverbund nach der Erfindung ist denkbar einfach. Nach der Fertigung der Einzelrohre und deren paralleler Erstreckung werden die Verbindungsbänder entweder einseitig auf den zugeordneten Rohroberflächen festgelegt oder durch eine einfache Wickeleinrichtung spiralig mit im Abstand voneinander stehenden Wendeln aufgebracht.The combination of the individual pipes to form the pipe network according to the invention is very simple. After manufacturing of the individual pipes and their parallel extension the connecting straps are either one-sided on the assigned pipe surfaces or by a simple spiral winding device with spaced apart standing spirals applied.

In der Zeichnung sind Ausführungsbeispiele des Rohrverbundes nach der Erfindung schematisch dargestellt; es zeigt:In the drawing there are exemplary embodiments of the tube assembly represented schematically according to the invention; it shows:

Fig. 1 den Rohrverbund mit Verbindungsbändern und parallel nebeneinander angeordneten Einzelrohren. Fig. 1 shows the pipe network with connecting bands and parallel arranged individual tubes.

Fig. 2 den zusammengeklappten Rohrverbund Fig. 2 shows the folded pipe assembly

Fig. 3 den Rohrverbund nach Fig. 1 mit spiralig umwickeltem Verbindungsband Fig. 3 shows the tube assembly of FIG. 1 with a spirally wrapped connecting band

Der in Fig. 1 gezeigte Rohrverbund besteht aus den vier Einzelrohren 11, 12, 13, 14. An definierten Oberflächenbereichen der Einzelrohre 11, 12, 13, 14 sind die Verbindungsbänder 2, 3 festgelegt. The tube assembly shown in FIG. 1 consists of the four individual tubes 11 , 12 , 13 , 14 . The connecting bands 2 , 3 are fixed to defined surface areas of the individual tubes 11 , 12 , 13 , 14 .

In der gezeigten Darstellung sind jeweils zwei Schweißstellen 21, 22, 31, 32 enthalten, über die die Verbindungsbänder 2, 3 auf den definierten Oberflächenbereichen der Einzelrohre 11, 12, 13, 14 festgelegt sind.In the illustration shown, two welding points 21 , 22 , 31 , 32 are contained, via which the connecting bands 2 , 3 are fixed on the defined surface areas of the individual pipes 11 , 12 , 13 , 14 .

Die Verbindungsbänder 2, 3 können in beliebig wählbarem Abstand auf den Oberflächen der Einzelrohre 11, 12, 13, 14 festgelegt werden. Neben dem beschriebenen Ultraschallverschweißen können auch andere Schweißverfahren sowie ein Verkleben der Bänder 2, 3 mit den zugeordneten Oberflächen der Einzelrohre 11, 12, 13, 14 eingesetzt werden. Vorraussetzung hierzu ist die Wahl eines entsprechenden Klebstoffes.The connecting bands 2 , 3 can be fixed at any desired distance on the surfaces of the individual tubes 11 , 12 , 13 , 14 . In addition to the ultrasonic welding described, other welding methods and gluing of the strips 2 , 3 to the associated surfaces of the individual tubes 11 , 12 , 13 , 14 can also be used. The prerequisite for this is the choice of an appropriate adhesive.

In der im Fig. 1 gezeigten horizontalen Erstreckung kann der Rohrverbund aufgrund der dem Kunststoff innewohnenden Flexibilität leicht getrommelt werden. Die festgelegten Bänder 2, 3 auf den definierten Oberflächenbereichen der Einzelrohre 11, 12, 13, 14 reichen hierbei aus, um den Rohrverbund während des Trommelns, während der anschließenden Lagerung und beim Wiederabrollen von der Trommel zusammenzuhalten.In the horizontal extent shown in FIG. 1, the tube assembly can be easily drummed due to the flexibility inherent in the plastic. The defined bands 2 , 3 on the defined surface areas of the individual tubes 11 , 12 , 13 , 14 are sufficient here to hold the tube assembly together during the drumming, during the subsequent storage and when re-rolling the drum.

Fig. 2 zeigt den Rohrverbund 1 im zusammengeklappten Zustand. Die Einzelrohre 11, 12, 13, 14 sind dabei in der Richtung zusammengelegt, die durch die aufgebrachten Verbindungsbänder 2, 3 definiert ist. Fig. 2 shows the pipe assembly 1 in the folded state. The individual tubes 11 , 12 , 13 , 14 are folded together in the direction defined by the connecting bands 2 , 3 applied.

Fig. 3 zeigt den Rohrverbund nach Fig. 1 mit einem Verbindungsband 2, welches spiralig um die gestreckt nebeneinander liegenden Einzelrohre 11, 12, 13, 14 gewickelt ist. Das Verbindungsband 2 kann ebenfalls nur durch zwei Schweißstellen 21, 22 an jeder zugeordneten Oberfläche der Einzelrohre 11, 12, 13, 14 festgelegt sein. Die erfindungsgemäße Anordnung der Verbindungsbänder 2, 3 kann derart erfolgen, daß die Einzelrohre 11, 12, 13, 14 in definiertem Abstand voneinander ausgestreckt nebeneinander angeordnet sind. Der Vorteil dieser Anordnungsart wird darin gesehen, daß der so geschaffene Rohrverbund 1 nicht nur in radialer Richtung zusammengeklappt werden kann, sondern daß die Einzelrohre 11, 12, 13, 14 sich auch in axialer Richtung gegeneinander verschieben lassen. Dies ist besonders wichtig bei der Verlegung des Rohrverbundes 1 in Kurven. Hier kann der Abstand der Wendel des Verbindungsbandes 2 zueinander entsprechend den Anforderungen bei der Verlegung des Rohrverbundes so gewählt werden, daß die bei der Verlegung zu bewältigenden Krümmungen beispielsweise des in der Erde befindlichen Kabelschutzrohres durch die axiale Bewegbarkeit der Einzelrohre untereinander von vornherein berücksichtigt ist. FIG. 3 shows the tube assembly according to FIG. 1 with a connecting band 2 , which is wound spirally around the individual tubes 11 , 12 , 13 , 14 lying stretched next to one another. The connecting band 2 can likewise only be fixed by two welding points 21 , 22 on each assigned surface of the individual tubes 11 , 12 , 13 , 14 . The arrangement of the connecting straps 2 , 3 according to the invention can be carried out in such a way that the individual tubes 11 , 12 , 13 , 14 are arranged next to one another at a defined distance from one another. The advantage of this type of arrangement is seen in the fact that the tube assembly 1 created in this way can not only be folded in the radial direction, but that the individual tubes 11 , 12 , 13 , 14 can also be moved relative to one another in the axial direction. This is particularly important when laying pipe system 1 in curves. Here, the distance of the helix of the connecting band 2 to one another can be selected in accordance with the requirements when laying the pipe assembly so that the curvatures to be managed during the laying, for example of the cable protection pipe located in the ground, are taken into account from the start by the axial mobility of the individual pipes.
