Abstract

The invention relates to the use of a sealing ring, which consists of rubber or a rubber-like material, exhibits anchorage feet and, during casing, is coupled to an auxiliary profile which, from a technical point of view, is matched optimally to the sealing ring, for sealing the coupling region of glass-fibre-reinforced pipes.

Description

Dichtringe gemäß Merkmale a) bis c) sind bekannt (DE-OS 35 07 909), wobei ihr Einsatz bisher auf Muffenrohre aus Beton oder Stahlbeton zur Ableitung von Abwasser und Regenwasser begrenzt war.Sealing rings according to features a) to c) are known (DE-OS 35 07 909), whereby their use so far on sleeve pipes Concrete or reinforced concrete for draining waste water and Rainwater was limited.

Aufgabe der Erfindung ist es, derartige Dichtringe zum Abdichten des Kopplungsbereiches von GFK-Rohren, u. z. GFK-Muffenrohren (System A) sowie von muffenlosen GFK- Rohren (System B) zu verwenden.The object of the invention is to provide such sealing rings Sealing the coupling area of GRP pipes, u. e.g. GRP sleeve pipes (system A) and sleeve-free GRP Pipes (system B).

GFK-Rohre werden auf Stahldornen gefertigt. Im Kopplungsbereich wird auf den zylindrischen Dorn zunächst der Hilfsprofil-Ring mit einer Vorspannung von etwa 5% aufgezogen. In die ringförmige Nut des Hilfsprofiles wird dann die Dichtung eingesetzt, die ebenfalls eine Vorspannung von etwa 5% im Ring aufweisen sollte. Dorn und Hilfsprofil werden sodann mit einem Trennmittel versehen, um später diese Teile vom fertigen GFK-Rohr entfernen zu können.GRP pipes are made on steel mandrels. In the coupling area the auxiliary profile ring is placed on the cylindrical mandrel with a preload of about 5%. In the the groove of the auxiliary profile then becomes the seal used, which also has a preload of about 5% should have in the ring. Thorn and auxiliary profile are then provided with a release agent to later remove these parts from the to be able to remove the finished GRP pipe.

Danach wird zunächst eine Reinharzschicht, gegebenenfalls auch mit abriebfesten Zuschlagstoffen gefüllt, auf den Wickelkern aufgetragen, und mit einer weiteren Reinharzschicht mit Vliesverstärkung auf mindestens 1 mm Dicke gebracht. Eine geringe Anzahl von Wickel-Rovings, breit gefächert, wird durch ein Harzband geführt, nimmt kurz vor Erreichen der Wickelform geschnittene Rovings in Wirrlagen auf und verdichtet und entlüftet sich durch den Druck gegen die Form. After that, a pure resin layer is applied, if necessary filled with abrasion-resistant aggregates on the winding core applied, and with another pure resin layer with Fleece reinforcement brought to a thickness of at least 1 mm. A small number of winding rovings, diversified passed through a resin ribbon, takes shortly before reaching the Wrapped rovings cut in confusion and compacted and vented by pressing against the mold.  

Jeweils parallel zu diesem Vorgang wird die Kernform am Scheitelpunkt mit einer bestimmten Menge Quarzsand beschickt, so daß ein wechselweiser Aufbau Glas-Harz/Sand-Harz entsteht. Der nach dieser Technik entstandene Sandwich-Charakter verleiht dem Rohr eine sehr hohe Steifigkeit und es ist auch unempfindlich gegen die Beanspruchungen durch den Baustellenbetrieb. Das Wickelverfahren ist geeignet zur Herstellung von kreisrunden GFK-Rohren und anders geformten Profilen, wie z. B. Ei-Formprofilen.In parallel to this process, the core shape is on A certain amount of quartz sand is fed to the vertex, so that an alternating structure of glass-resin / sand-resin is created. The sandwich character created using this technique gives the tube a very high rigidity and it is also insensitive to the stresses caused by the Construction site operation. The winding process is suitable for Manufacture of circular GRP pipes and other shaped ones Profiles such as B. egg shape profiles.

Beim Erhärten zieht sich der Sandwichaufbau zusammen, so daß ein relativ hoher Druck auf Dichtungsring und Hilfsprofilring eintritt. Von daher ist es zweckmäßig, das Hilfsprofil aus einer EPDM-Mischung mit einer Härte von 70 Shore A einzusetzen, und im übrigen dem Hilfsprofil keine Hohlräume zur Materialersparnis zu gönnen.When hardening, the sandwich structure contracts, so that a relatively high pressure on the sealing ring and auxiliary profile ring entry. It is therefore advisable to use the auxiliary profile an EPDM mixture with a hardness of 70 Shore A use, and otherwise the auxiliary profile no voids Treat yourself to material savings.

Sobald das Rohr erhärtet ist, wird es vom Wickeldorn heruntergeschoben; dann wird das Hilfsprofil herausgenommen und steht für eine erneute Anwendung zur Verfügung.As soon as the pipe has hardened, it is removed from the winding mandrel pushed down; then the auxiliary profile is removed and is available for reuse.
