Abstract
Description
Mehrwandrohr aus elastischen Endlosrohren - Zusatzanmeldung - zum ~Kunststoff-Mehrwandrolir" Beschreibung Der Erfindungsgegenstand ist eine neuheitliche Herstellungsweise und Konstruktionsform für elastische Röhren. Er ergab sich aus einer Weiterentwicklung und der Verwertung von Erfahrungen bei der Arbeit zur Produktionsreife des Kunststoff-Mehrwandrohres (Hauptanmeldung).Multi-wall pipe made of elastic endless pipes - additional registration - for ~ Plastic multi-wall roller blind "Description The subject of the invention is a novel one Production method and construction form for elastic tubes. He surrendered from a further development and the utilization of experiences in the work to production readiness of the plastic multi-wall pipe (main application).
Mit der zusätzlichen neuheitlichen technischen Lösung ist der Einsatzbereich noch erweitert worden bzw. die Herstellung vereinfacht und kostensparender geworden.With the additional, innovative technical solution, the area of application is has been expanded or the production has become simplified and cost-saving.
Die technische Lösung ist in der beiliegenden Zeichnung#systematisch erläutert. Es zeigen: Fig. 1: im Mantelschnitt eine Röhre mit drei Wickelrohrlagern Fig. 2: wie Fig. 1: jedoch mit zwei Widkelrohrlagern, und unterschiedlichen Rohrdurchmessern.The technical solution is # systematic in the attached drawing explained. The figures show: FIG. 1: a jacket section of a tube with three wound tube bearings Fig. 2: Like Fig. 1: but with two Widkel tube bearings and different tube diameters.
Fig. 3: wie Fig, 1: jedoch mit Rohren in der Mittelzone mit größerem Durchmesser Fig. 4: wie Fig. 1: jedoch mit nur einseitigen Wickelrohren und Rohrabstand.Fig. 3: like Fig. 1: but with pipes in the central zone with larger ones Diameter Fig. 4: like Fig. 1: but with only one-sided winding tubes and tube spacing.
Fig. 5: im Mantelschnitt den Stoß von Röhren Fig. 6: wie Fig. 5: jedoch mit Dichtungsband-Einlage Fig, 7: in Queransicht die einzelnen Wandelemente-vor der gegenseitigen kraftschlüssigen Verbindung Fig. 8: wie Fig. 7: jedoch nach der kraftschlüssigen Verbindung der Wandelemente und in der Funktionsform.Fig. 5: In the jacket section, the joint of tubes Fig. 6: As Fig. 5: but with sealing tape insert Fig, 7: in front of the individual wall elements in a transverse view the mutual non-positive connection Fig. 8: as Fig. 7: but after the frictional connection of the wall elements and in the functional form.
Die Aufgabe, aus endlosen elastischen Rohren funktionstüchtige Röhren für Kanäle, Schächte, Durchlässe zu fertigen, wurde mit größerem Einsatzbereich und leichterer Herstellung wie folgt gelöst: Endlose, elastische Rohre (2), vorzugsweise aus Stoffen wie PVC, PE werden mehrreihig mit gleichen oder funktionsbedingt abgestuft gewählten Durchmesser spiralförmig gewickelt. Beim Wickeln oder unmittelbar danach oder erst vor dem endgültigen Einbau werden die einzelnen Wandelemente - Innenröhre (1) Wickelbereich (2), Außenröhre (3) kraftschlüssig verklebt oder verschweißt, in Ausnahmefällen vernietet oder verschraubt.The task of making functional tubes from endless elastic tubes to manufacture ducts, manholes, culverts became with a larger area of application and easier production solved as follows: Endless, elastic tubes (2), preferably Made of materials such as PVC, PE are graded in multiple rows with the same or function-related selected diameter wound spirally. At the Wrap or immediately afterwards or before the final installation, the individual wall elements - Inner tube (1) winding area (2), outer tube (3) positively glued or welded, in exceptional cases riveted or screwed.
Die Transport- oder Einbau- bedingte Röhrenlänge verlangt einen Stoß, der mittels Überlappung der Enden (5,6) einfach herstellbar ist. Die Dichtheit wird durch Dichtungsbänder (7) gesichfiert. Ferner können mittels Stabilisatoren (8) wie Stützen, Streben die Wandelemente zur Funktionsform stabilisiert werden.The tube length due to transport or installation requires a joint, which can be easily produced by means of overlapping the ends (5, 6). The tightness will secured by sealing strips (7). Furthermore, stabilizers (8) like supports, struts the wall elements are stabilized to the functional form.
