Schröder, Günter, Riesebusch 14, 23611 Bad Schwartau "Steckverbindung für Rohre" Schröder, Günter, Riesebusch 14, 23611 Bad Schwartau "Plug connection for pipes"

Die Neuerung bezieht sich auf eine Steckverbindung für RohreThe innovation relates to a plug connection for pipes

aus thermoplastischem Kunststoff.made of thermoplastic material.

Rohre aus thermoplastischen Kunststoffen finden in der Technik zunehmend Verwendung zur Herstellung von Leitungssystemen für den Transport verschiedener Medien. Ein großer Vorteil derPipes made of thermoplastics are increasingly being used in technology to produce pipe systems for the transport of various media. A major advantage of

Rohre aus thermoplastischen Kunststoffen ist darin zu sehen, daß sie vielen negativen Einflüssen der Umwelt widerstehen und beständig gegenüber zahlreichen aggressiven Stoffen sind. Geringes Gewicht und Flexibilität vereinfachen ihren Transport und erleichtern es, sie zu verlegen.The advantage of pipes made of thermoplastics is that they can withstand many negative environmental influences and are resistant to numerous aggressive substances. Their low weight and flexibility simplify their transport and make them easier to lay.

Zur Verbindung der Rohre ist es bekannt geworden, die Rohre mit einer Muffe und einem in die Muffe maßlich eingepaßten Einsteckende zu versehen. Hierbei werden das Einsteckende und die Muffe unter der Einwirkung von einem in dem EinTo connect the pipes, it has become known to provide the pipes with a socket and a spigot end that is dimensionally fitted into the socket. In this case, the spigot end and the socket are connected under the influence of a

Durch das Schweißen werden dann die in die geeignete Endposition mechanisch zusammengefügten Rohrabschnitte miteinander stoffchange their position relative to each other. This makes it very easy to adapt to the local conditions and requirements that arise when laying pipe sections. The pipe sections are then mechanically joined together in the appropriate final position by welding.

Diese der Neuerung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert. Advantageous embodiments are explained in the subclaims.

Mit anderen Worten ausgeführt, wird vorgeschlagen, daß im Einsteckendenbereich der Bereich, der mit der Heizleitung versehen ist, durch Ringdichtung gegenüber dem übrigen Bereich der Rohre abgesichert ist. Üblicherweise werden die Rohre im trockenen Bereich ineinandergesteckt, und nun verhindern die vorgesehenen Ringdichtungen beiderseits des Heizbereiches in Längsachse des Rohres gesehen, daß, wenn dieses Rohr aufIn other words, it is proposed that in the insertion end area, the area provided with the heating cable is secured against the rest of the pipe area by a ring seal. Usually, the pipes are inserted into one another in the dry area, and now the ring seals provided on both sides of the heating area in the longitudinal axis of the pipe prevent that, when this pipe is on

der Grabensohle beispielsweise im Wasser oder im feuchten Bereich verlegt wird, Wasser in den Bereich der Schweißstelle eindringen kann.If the trench bottom is laid in water or in a damp area, for example, water can penetrate into the area of the welding point.

Hierbei kann gemäß einem weiteren Merkmal der Neuerung derAccording to another feature of the innovation, the

vordere Bereich der Ringdichtung durch eine angeformte Einführnase am Einsteckende so gesichert werden, daß beim Ineinanderstecken der Rohre ein Abstreifen der vorderen Ringdichtung verhindert wird.The front area of the ring seal is secured by a molded-on insertion lug at the insertion end so that the front ring seal is prevented from being stripped off when the pipes are inserted into one another.

Als Dichtungen können die unterschiedlichsten zum Stand der Technik gehörenden Dichtungsarten eingesetzt werden, z. B. Rollringe, Lippendichtungen, Flachdichtungen usw. Das Dichtungsmaterial selbst besteht aus abwasserbeständigen Werkstoffen. A wide variety of state-of-the-art seal types can be used as seals, e.g. rolling rings, lip seals, flat seals, etc. The sealing material itself consists of wastewater-resistant materials.

Durch diesen Vorschlag wird erreicht, daß kein Wasser oder Feuchtigkeit an die Heizdrähte gelangen kann und die Schweißung daher technisch einwandfrei durchgeführt werden kann.This suggestion ensures that no water or moisture can reach the heating wires and the welding can therefore be carried out in a technically flawless manner.

Ein Ausführungsbeispiel der Neuerung zeigt die beigefügte Zeichnung. In der Zeichnung ist ein Abschnitt eines Einsteckendes 1 dargestellt. Auf der nach außen gerichteten Seite des Einsteckendes 1 ist eine Heizwendel 2 vorgesehen, und inAn example of the innovation is shown in the attached drawing. The drawing shows a section of a spigot end 1. A heating coil 2 is provided on the outward-facing side of the spigot end 1, and in

Längsachse des Rohres gesehen wird diese Heizwendel 2 von zwei Ringdichtungen 4 und 5 abgeschlossen, wobei diese beiden Ringdichtungen 4 und 5 ein Dichtungssystem 3 ergeben.Viewed along the longitudinal axis of the pipe, this heating coil 2 is closed by two ring seals 4 and 5, whereby these two ring seals 4 and 5 form a sealing system 3.

Weiterhin ist aus der Zeichnung ersichtlich, daß im vorderen BeFurthermore, it can be seen from the drawing that in the front

reich des Einsteckendes 1 eine Einführnase 6 angeordnet sein kann, die die vordere Ringdichtung derart schützt, daß beim Einschieben des Einsteckendes in die zugehörige in der Zeichnung nicht dargestellte Muffe ein Abstreifen der vorderen Ringdichtung nicht möglich ist.an insertion nose 6 can be arranged in the area of the insertion end 1, which protects the front ring seal in such a way that when the insertion end is inserted into the associated sleeve (not shown in the drawing), it is not possible to strip off the front ring seal.
