Description

Rohrverbindung an Kunststoffrohren ====================2============= Die Erfindung betrifft eine Rohrverbindung an Kunststoffrohren,bei welcher das muffenartig erweiterte Rohrende Verstärkung erhalten soll. Pipe connection on plastic pipes ==================== 2 ============= The invention relates to a pipe connection on plastic pipes, in which the sleeve-like extended pipe end reinforcement is to receive.

Bei Kunststoffrohren,z.B. aus Hart -PVC für die Abwasser -Ableitung,hat es sich als nachteilig erwiesen,dass nach dem Zusammenstecken der Rohrabschnitte infolge mechanischer Beanspruchung Zein Reissen des über das einlaufende Rohr ge -steckten,muffenartig erweiterten Rohrendes auftreten kann.In the case of plastic pipes, e.g. made of hard PVC for waste water drainage it has proven to be disadvantageous that after the pipe sections have been plugged together due to mechanical stress Zein tearing of the ge over the incoming pipe -stuck, socket-like expanded pipe end can occur.

solche Risse können z. B. auch nach dem Verlegen unter Putz auftreten,vor allem auch denn, wenn eine Versprödung des als Werkstoff für die Rohre meist verwendeten Hart - PVC z. B.such cracks can e.g. B. also occur after laying under plaster before especially if there is an embrittlement of the material mostly used for the pipes Rigid PVC e.g. B.

durch Kälte vorliegt. In diesen Fällen tritt ein vom Rande ausgehendes Einreissen des muffenartig erweiterten Röhren -enues auf,das zur Undichtheit führt.due to the cold. In these cases something emanating from the edge occurs Tearing of the sleeve-like expanded pipe ducts, which leads to the leak.

Die Erfindung hat die Aufgabe, durch nachträgliche Bewick -lung dieses Rohrendes mit einem zugfesten Werkstoff eine Ver -stärkung zu erzielen,die das Einssissn des Rohrendes verhin -dert. Erfindungsgemäss wird dies dadurch erzielt,dass eine nachträgliche Bewickelung des Rohrendes mit einem zugfesten Werkstoff erfolgt.The invention has the task of this by subsequent Bewick -lung Pipe end with a tensile material to achieve a reinforcement that the Einssissn the end of the pipe prevented. According to the invention this is achieved in that a subsequent wrapping of the pipe end with a tensile material.

Gemäss einer Ausbildung der Erfindung erfolgt die Verstärkung durch Bewickelung mit einem zugfesten,selbst#lebenden Band, welche erfindungsgemäss aus einem, mit in Längsrichtung ver -laufenden Glesfasern versehenen Band bestehen kann.According to one embodiment of the invention, the reinforcement takes place through Wrapping with a tensile, self-living tape, which according to the invention consists of can consist of a tape provided with glass fibers running in the longitudinal direction.

tine weitere Ausbildung der Erfindung besteht darin,dass die Verstärauny durch Bewickelung mit einem Metalldraht erfolgt. Erfindungsgemäss kann weiterhin die Bewickelung auch mit einem kunststoffbeschichteten Metalldraht, vorzugsweise Eisendraht, erfolgen.Another embodiment of the invention is that the Verärauny done by wrapping a metal wire. According to the invention can still be wrapped with a plastic-coated metal wire, preferably iron wire.

Eine weitere erfindungsgemässe Massnahme besteht darin, dass nach dem Bewickeln eine kurzzeitige Erhitzung des Metalldrahtes bis zum Verschmeizen mit dem Trägerroht er -folgt. Dies kann erfindungsgemäss durch kurzzeitige Er -hitzung des Metalldrahtes mittels Stromdurchflusses er -folgen.Another measure according to the invention is that after After winding, a brief heating of the metal wire until it melts with the carrier tube. According to the invention, this can be achieved by brief heating of the metal wire by means of current flow.

Eine weitere erfindungsgemässe Massnahme besteht darin'dass die Kunststoffbeschichtung des Metalldahtes aus einem thermoplastischen Werkstoff besteht.Another measure according to the invention is that the plastic coating of the metal wire consists of a thermoplastic material.

Die Erfindung wird an Hand von Zeichnungen beschrieben Fig. 1 zeigt eine Rohrverbindung'bei welcher die muffen -artig erweiterten Rohrenden verstärkt sind.The invention is described with reference to drawings, FIG. 1 shows a pipe connection in which the sleeve-like widened pipe ends are reinforced are.

Fig. 2 zeigt im Schnittbild eine Rohrverbindung gemäss der Erfindung.Fig. 2 shows a sectional view of a pipe connection according to the invention.

Fig. 3 zeigt den zur Verstärkung des Rohrendes vorgesehenen kunststoffbeschichteten Draht.3 shows the plastic-coated one provided for reinforcing the pipe end Wire.

Fig. 4 zeigt ein Rohrende mit aufgewickelter Drahtver -stärkung,wobei die Erhitzung derselben mittels Strom -durchfluss erfolgt.Fig. 4 shows a pipe end with wound wire reinforcement, wherein they are heated by means of a current flowing through them.

In Fig. 1 ist eine Rohrabzweigung 6 dargestellt,welche mit den beiden einlaufenden Rohren 7 und 8 #erbunden ist.In Fig. 1, a pipe junction 6 is shown, which with the two incoming pipes 7 and 8 # is connected.

Bei der Rohrverbindung mit Rohr 7 ist gezeigt,wie eine Ver -stärkung 2 des muffenartig erweiterten Rohrendes 1 durch Bewickelung mit einem zugfesten,selbstklebenden Band 3 erfolgen kann.Hierbei ist es zweckmässig,zur Erreichung einer ausreichenden Festigkeit ein selbstklebendes Band mit längslaufender Glasfaserverstärkung zu verwenden. Hier -zu genügen im allgemeinen zwei bis fünf Lagen, welche z. B. durch eine automatische Wickelvorrichtung im Anschluss an die Rohrherstellung aufyebbacht werden können.In the case of the pipe connection with pipe 7, it is shown how a reinforcement 2 of the socket-like expanded pipe end 1 by wrapping with a tensile, self-adhesive Volume 3 can be done. In this case, it is useful to achieve a sufficient Strength to use a self-adhesive tape with longitudinal glass fiber reinforcement. For this purpose, two to five layers are generally sufficient, which z. B. by an automatic Winding device can be attached after the pipe production.

bei der Verbindung mit Rohr 8 ist eine Verstärkung 2 des muffenartig erweiterten Rohrendes 1 durch Bewickelung mit einer Lage eines Drahtes 4 durchgeführt. Zweckmässiger -weise wird hierzu ein Draht verwendet, welcher mit einer Kunststpffschicht versehen ist. In der Schnittdarstellung nach Fig. 2 wird eine solche Verstärkung 2 des Rohrendes 5 näher erläutert. Sie erfolgt hier durch Aufwickeln einer Lages des Drahtes 4,4a, wobei dieser Draht 4 entweder Blank sein kann oder, wie dargestellt, eine Kunststoffbeschich -tung 4a trägt. plit 8 ist das einlaufende Rohr bezeichnet, welches in das muffenartig erweiterte Rohrende 1 eingesteckt ist. vie Rolldichtung 9 sorgt für einen dichten Abschluss der Aohrverbinduny.when connected to pipe 8, a reinforcement 2 of the sleeve-like extended pipe end 1 carried out by wrapping a layer of wire 4. For this purpose, a wire is expediently used which has a synthetic material layer is provided. In the sectional view of FIG. 2, such a reinforcement 2 of the pipe end 5 explained in more detail. It takes place here by winding up a layer of the wire 4, 4a, this wire 4 either being bare or, as shown, a plastic coating 4a carries. plit 8 is the name of the incoming pipe, which is inserted into the socket-like widened pipe end 1. vie roll seal 9 ensures a tight seal on the Aohrverbinduny.

Der Aufaau des zur Verstärkung verwendeten Drahtes ist in Fig. 3 näher dargestellt, wobei mit 4 der Draht selbt, mit 4a seine Kunststoffbeschichtung bezeichnet ist. Als Werkstoff für den Draht ist Eisen am geeignetsten, da es für die nachfolgende Erhitzung mit Stromdurchfluss infolge seines höheren spezifischen liiderstandes besser geeignet ist als z. B. Kupfer. Die Beschichtung besteht aus einem thertnoplastischen Kunststoff, wobei am besten ein dem Rohr -material entsprechender Kunststoff,beispielsweise Poly -vinylchlorid verwendet wird.The structure of the wire used for reinforcement is shown in more detail in FIG shown, with 4 the wire itself, with 4a denotes its plastic coating is. Iron is the most suitable material for the wire, as it is used for the following Heating with current flow due to its higher specific resistance is more suitable than z. B. Copper. The coating consists of a thermoplastic Plastic, preferably a plastic corresponding to the pipe material, for example Polyvinyl chloride is used.

In Fig. 4 wird gezeigt,wie nach dem Bewickeln des Rohr -endes 5 eine kurzzeitige Erhitzung des kunststoffbeschich -teten Drahtes 4,4a erfolgt. Hierzu werden die beiden Draht -enden lo an die 5eKundarwicklung des Netztransformators 11 angeschlossen. Ein von einem nicht dargestellten Zeitschalt -werk betätigter Kontakt 12 schliesst kurzzeitig den Strom -kreis. Stromstärke und Zeitdauer werden so gewählt1 dass die Kunststoffbeschichtung 4a des Drahtes 4 kurzzeitig schmilzt. Dadurch verbinden sich sowohl die nebeneinander liegenden Drahtverbindungen miteinander als auch mit dem thermoplastischen Werkstoff des Rohrendes 5. Nach Abkühlung, die z. B. durch Anblasen mit Pressluft beschleunigt werden kann, ist ein fester Sitz der Wicklung 2 erreicht, sodass die Drahtenden lo abgeschnitten werden können.In Fig. 4 it is shown how after winding the pipe end 5 a Brief heating of the plastic-coated wire 4,4a takes place. For this the two wire ends lo to the 5th secondary winding of the mains transformer 11 connected. One operated by a timer, not shown Contact 12 briefly closes the circuit. Amperage and duration will be selected1 so that the plastic coating 4a of the wire 4 melts briefly. As a result, the wire connections lying next to one another connect to one another as well as with the thermoplastic material of the pipe end 5. After cooling down, the z. B. can be accelerated by blowing compressed air, is a tight fit the winding 2 reached so that the wire ends lo can be cut off.

Derselbe Vorgang ergibt sich im Wesentlichen auch,wenn ein Draht ohne Kunststoffbeschichtung verwendet wird. In diesem Falle ist es jedoch zweckmässig, die Drahtoberfläche durch Lackieren oder Oxydation so zu isolieren, das zwischen den einzelnen Windungen kein Nebenschluss auftreten kann. Die Verklebung des Drahtes erfolgt dann mit dem thermoplastischen Werkstoff des Rohrendes 5, wenn die Erhitzung mittels Strom -#d#urchflusses erfolt.Essentially the same process also occurs if a wire is used without a Plastic coating is used. In this case, however, it is advisable to to isolate the wire surface by painting or oxidation in such a way that the between no shunt can occur between the individual windings. The bonding of the wire then takes place with the thermoplastic material of the pipe end 5 when the heating by means of current - # d # flow.
