Description
Verfahren zum Herstellen von Rohrleitungen für elektrische Kabel oder für ähnliche Zwecke. Die Erfindung bezieht sich auf die Herstellung von solchen Rohrleitungen, die vornehmlich aus Zenientleitungen. mit einem oder mehreren abgleich zueinander liegenden Kanälen bestehen, wie sie allgemein zumVerlegen von Kabeln u.dgl. benutzt werden.Method of making pipelines for electrical cables or for similar purposes. The invention relates to the manufacture of such Pipelines, which are primarily made up of zenient lines. with one or more comparisons There are mutually lying channels, as are generally used for laying cables and the like.
Das Neue gemäß der Erfindung besteht darin, daß der aus einem Gummirohr bestehende Formkern in Abständen in Tragstücke eingesetzt und dann die Gußmasse aufgefüllt wird, wonach der Fornikern herausgezogen wird, während die Tragstücke in der Gußmasse verbleiben. Zweclinnäßig erhalten die Tragstücke seitliche äußere Abstandhalter.The novelty according to the invention is that the one made of a rubber tube existing mandrel inserted at intervals in support pieces and then the casting compound is filled, after which the Fornikern is pulled out while the support pieces remain in the casting compound. Purposely, the supporting pieces are given lateral outer ones Spacers.
Die Erfindung ist auf der Zeichnung veranschaulicht.The invention is illustrated in the drawing.
Abb. i zeigt im Langschnitt einen beliebigen Abschnitt eines einzigen in der Herstellung begriffenen Kanals einer Leitung und Abb. 2 einen Querschnitt einer fertigen Mehrfachleitung in der Erde.Fig. I shows in a long section any section of a single one in the production of a duct of a line and Fig. 2 is a cross-section a completed multiple line in the earth.
Das in bekannter Weise als Formkern dienende Gummirohr2 wird in Abständen in Tragstücke3 eingesetzt. Diese Tragstücke3 bestehen aus zusammensetzbaren Blöcken in Kreisabschnittform, die den Kern umgeben und ein Durchsacken und seitliches Abweichen desselben verhindern.The rubber tube2, which is used as a mold core in a known manner, is spaced apart used in support pieces3. These support pieces3 consist of assemblable blocks in circular segment shape surrounding the core and sagging and sideways deviating prevent the same.
Befindet sich der Kern in der richtigen Lage, so wird die Gußmasse i in einem Arbeitsgang unter und um den Kern herumgegossen, und zwar so weit, daß am Ende des Abschnittes noch ein Stück desselben aus dem fertigen Guß hervorragt. Nachdem der Guß trocken und hart geworden ist, wobei die hierzu erforderliche Zeit von der Beschaffenheit der Gußmasse und der zum Abbinden notwendigen Dauer abhängt, wird der Kern in Richtung des Pfeiles mittels geeigneter Mittel bis in die in Abb. i dargestellte Lage gezogen, wobei die Tragstücke in dem fertigen Guß belassen werden.If the core is in the correct position, the casting compound will be i poured under and around the core in one operation to the point that At the end of the section a piece of the same protrudes from the finished casting. After the cast has become dry and hard, taking the time required to do so depends on the nature of the casting compound and the time required for setting, If the core is moved in the direction of the arrow by means of suitable means down to the position shown in Fig. i position shown drawn, the support pieces are left in the finished casting.
Der herausragende Teil -des Kernes wird nun zwecks Gießens eines weiteren Abschnittes auf neue TragstÜcke3 gesetzt und zur Herstellung eines weiteren Abschnittes. des Kanals in der bereits beschriebenen Weise geschritten. Das Verfahren wird dann so lange wiederholt, bis die gewünschte Leitungslänge erreicht ist.The protruding part of the core is now used for casting another Section set on new TragstÜcke3 and for the production of another section. of the canal in the manner already described. The procedure will then Repeatedly until the required cable length is reached.
Bei der Herstellung von Leitungen.hüt mehreren abgleichen Kanälen 5 werden die Kerne in Tragstücke mit seitlichen Ansätzen 3 a eingesetzt (Abb. 2), welche als Abstandhalter für die Kerne dienen.In the production of Leitungen.hüt multiple match channels 5, the cores are used in supporting pieces with lateral extensions 3a (Fig. 2) which serve as spacers for the cores.
Es wird dann in diesem Falle mit der gleichzeitigen Herstellung sämtlicher Kanäle eines Abschnittes begonnen, und für die Herstellung eines weiteren Abschnittes werden die Kerne2 sämtlicher Kanäle herausgezogen (Abb. i), in entsprechender Weise gelagert und dann gleichzeitig umgossen usw., bis die gewünschte Länge der Leitung hergestellt ist.It is then in this case with the simultaneous production of all Channels of a section started, and for the production of another section the cores2 of all canals are pulled out (Fig. i), in a corresponding manner stored and then cast around at the same time, etc., until the desired length of the line is made.
