VERBINDUNGSELEMENT FÜR ROHRECONNECTING ELEMENT FOR PIPES
Die Neuerung bezieht sich auf ein Verbindungselement für Rohre, beispielsweise Kunststoffrohre, das als Einsteckmuffe ausgebildet ist, mit einem mittig angeordneten, umlaufenden ringförmigen Anschlag für die aufgeschobenen Rohrenden oder dgl.The innovation relates to a connecting element for pipes, for example plastic pipes, which is designed as a socket, with a centrally arranged, circumferential ring-shaped stop for the pushed-on pipe ends or the like.
Zur Verbindung von Rohren, beispielsweise Kabelkanalrohren oder Vortriebsrohren für unterirdische Kabelkanalanlagen, werden überwiegend Rohre aus thermoplastischem Kunststoff eingesetzt. Die Verbindung der Rohre untereinander geschieht dabei mit angeformten Klebmuffen, wobei die Klebmuffe im Bedarfsfalle zusätzlich mit dem Einsteckende des nächsten Rohres verklebt wird. Eine solche Maßnahme ist dann nötig, wenn mit Grundwasserandrang im Gebiete des Rohrschusses zu rechnen ist.Pipes made of thermoplastic are mainly used to connect pipes, for example cable duct pipes or jacking pipes for underground cable duct systems. The pipes are connected to one another using molded adhesive sleeves, whereby the adhesive sleeve is also glued to the insertion end of the next pipe if necessary. Such a measure is necessary if groundwater ingress is to be expected in the area of the pipe section.
Der Nachteil solcher Rohrverbindungen besteht darin,
daß eine Außendurchmesservergrößerung der Rohre durch die Muffe stattfindet. Die Folge davon ist, daß der
Rohrschuß an den Verbindungsstellen zweier Rohre
regelmäßig einen größeren Durchmesser aufweist als dazwischen. Dadurch werden bei der Verlegung von
Vortriebsrohren selbstverständlich auch größere Verdrängungs-
bzw. Bohrköpfe notwendig, die einen zusätzlichen Raum zwischen dem Erdreich und dem Vortriebsrohr
schaffen, der nur negative Auswirkungen hinsichtlich Kosten und späterem Erdreichverhalten bewirkt.
Zur Behebung dieses Nachteiles finden Rohre mit glei-The disadvantage of such pipe connections is that the outside diameter of the pipes is increased by the socket. The consequence of this is that the pipe section at the connection points between two pipes is usually larger in diameter than between them. This naturally means that larger displacement or drilling heads are required when laying jacking pipes, which create additional space between the ground and the jacking pipe, which only has negative effects in terms of costs and subsequent soil behavior.
To overcome this disadvantage, pipes with the same

chem Außendurchmesser, d.h. muffenlose Rohre Verwendung. Bei solchen Rohren wird an einem Ende ein Teil der Wanddicke außen und am anderen Ende ein entsprechendes Maß der Wanddicke innen entfernt. Dies bedingt größere Wanddicken als notwendig, d.h. für die Druckfestigkeit des Rohres ist nur der Teil der Restwanddicke maßgebend. chem outer diameter, i.e. socketless pipes are used. In such pipes, part of the wall thickness is removed on the outside at one end and a corresponding amount of the wall thickness is removed on the inside at the other end. This requires greater wall thickness than necessary, i.e. only part of the remaining wall thickness is decisive for the pressure resistance of the pipe.
Bei den bekannten Verbindungselementen kann es wegen Fertigungsto 1 eranzen vorkommen, daß in einem Falle Spitzende und Muffe nur sehr schwer, wenn überhaupt, steckbar sind; im anderen Fall kann sich das Spitzende in der Muffe dagegen leicht bewegen. In beiden Fällen ist jedoch mit bautechnischen Schwierigkeiten zu rechnen.With the known connecting elements, it can happen due to manufacturing tolerances that in one case the spigot and socket can only be connected with great difficulty, if at all; in the other case, the spigot can move easily in the socket. In both cases, however, constructional difficulties are to be expected.
Weiterhin ist es bekannt, übliche Muffenaufweitungen durch einen Einzug im Durchmesser zu ersetzen, d.h. die eigentliche Muffenverbindung zur Rohrinnenseite zu verlegen. Da es sich dabei um einen gewissen Stauchprozeß handelt, kann man davon ausgehen, daß dabei der Innendurchmesser des Vortriebsrohres um etwas mehr als zweimal der Wanddicke entsprechend verringert wird. Darüber hinaus muß auch noch ein gewisser Anschlag geschaffen werden, wenn die Andruckfläche in der Muffe kongruent mit der des übrigen Rohres zu sein hat.It is also known to replace conventional socket expansions with a reduction in diameter, i.e. to move the actual socket connection to the inside of the pipe. Since this involves a certain compression process, it can be assumed that the inside diameter of the jacking pipe is reduced by a little more than twice the wall thickness. In addition, a certain stop must also be created if the pressure surface in the socket has to be congruent with that of the rest of the pipe.
Die Neuerung, wie sie in den Ansprüchen beschrieben ist, löst die Aufgabe, eine Rohrverbindung zu schaffen, die die Nachteile der bekannten Rohrverbindungen nicht aufweist und darüber hinaus eine wirtschaftliche Fertigung erlaubt.The innovation, as described in the claims, solves the problem of creating a pipe connection that does not have the disadvantages of the known pipe connections and, moreover, allows economical production.
Der mit der Neuerung erzielte Vorteil besteht darin,The advantage achieved with the innovation is that

daß mit diesem Verbindungstei1, welches beispielsweise im Spritzgußverfahren herzustellen ist, die fertigungsbedingten Schwankungen beim Innendurchmesser der Rohre überbrückt werden. Dies geschieht durch die etwas konisch ausgebildeten Spitzenden des Verbindungselementes, die auf ihrer Oberfläche schmale, in sich auch wieder leicht konisch gestaltete, aber in der Längsrichtung ihrer Oberfläche zylindrisch verlaufende Rippen aufweisen.that with this connecting part, which can be manufactured using an injection molding process, for example, the manufacturing-related fluctuations in the inner diameter of the pipes are bridged. This is achieved by the slightly conical pointed ends of the connecting element, which have narrow ribs on their surface that are also slightly conical in shape, but cylindrical in the longitudinal direction of their surface.
Dadurch wird erreicht, daß sich auch bei verschiedenen Innendurchmessern der Rohre eine annähernd gleiche Einschubkraft ergibt. Außerdem ist eine derartige Verbindung zumindest feinsanddicht.This ensures that even with different internal diameters of the pipes, the insertion force is almost the same. In addition, such a connection is at least fine sand-tight.
Die Vorteile der neuerungsgemäß vorgeschlagenen Rohrverbindung liegen auch in der dadurch erhaltenen gleichmäßigen Außendurchmesser der damit ausgerüsteten Rohrschüsse, außerdem in der einfach herzustellenden, 1ängskraftsch 1üssigen Verbindung ohne jede Klebung oder Schweißung der Verbindungsstelle und deren wirtschaftlichen Herstellbarkeit.The advantages of the pipe connection proposed in accordance with the innovation also lie in the uniform external diameter of the pipe sections equipped with it, as well as in the easy-to-manufacture, longitudinally force-tight connection without any gluing or welding of the connection point and its economic manufacturability.
Die Neuerung ist nachstehend anhand eines in den Abbildungen dargestellten Ausführungsbeispieles näher er 1äuter t.The innovation is explained in more detail below using an example shown in the figures.

Thermop1 astspritzgußtei 1 1, das zwei Stutzen la und Ib besitzt, die von einem umlaufenden Anschlag Ic beginnend, nach außen leicht konisch ausgebildet sind, d.h. die Wanddicke ist am Ende der beiden Stutzen la und Ib etwas geringer als am Steg lc.Thermoplastic injection molded part 11, which has two nozzles la and Ib, which start from a circumferential stop Ic, and are slightly conical towards the outside, i.e. the wall thickness is slightly less at the end of the two nozzles la and Ib than at the web lc.
Die Innenwand dagegen verläuft, bis auf das äußerste Ende, zylindrisch.The inner wall, on the other hand, is cylindrical except for the outermost end.
Auf dem Unfang der Stutzen la und Ib sind mehrere verformbare, nach unten leicht konisch verlaufende, oben jedoch zylindrische Stege Id mit einer Fase an ihrem äußeren Ende vorgesehen. Damit wird erreicht, daß einerseits im Bereich der Verbindung zwischen dem Verbindungsstück 1 und den Rohrenden 2 evtl. Fertigungstoleranzen der Rohre ausgeglichen werden und eine 1ängskraftsch 1üssige Verbindung zwischen den beiden erzielt wird.On the circumference of the nozzles la and lb, several deformable webs Id are provided, which are slightly conical towards the bottom but cylindrical at the top and have a bevel at their outer end. This ensures that, on the one hand, in the area of the connection between the connecting piece 1 and the pipe ends 2, any manufacturing tolerances of the pipes are compensated for and a longitudinally force-tight connection between the two is achieved.
Die Spitzenden der Stutzen la und Ib sind zum einfachen Einschieben in die Rohrenden 2 mit einer Innenanschrägung von etwa 15° in bekannter Weise versehen.The spigot ends of the nozzles la and lb are provided with an internal bevel of approximately 15° in a known manner for easy insertion into the pipe ends 2.
An Stelle von Thermoplast als Material für das Verbindungselement können auch andere geeignete Materialien eingesetzt werden. Es ist auch möglich, auf ein Verbindungselement aus Metall oder anderen Stoffen eine Manschette aufzuschieben, die zwischen den Stutzen und den aufgeschobenen Rohrenden die gleiche Funktion wie das Verbindungselement aus einem Kunststoff übernimmt; denn die notwendigerweise verformbaren Stege Id, sind aus harten und spröden Materialien nicht zu realisieren. Instead of thermoplastic as the material for the connecting element, other suitable materials can also be used. It is also possible to slide a sleeve onto a connecting element made of metal or other materials, which performs the same function between the nozzles and the pushed-on pipe ends as the connecting element made of plastic; because the necessarily deformable webs Id cannot be made from hard and brittle materials.
