Abstract
Description
Die Erfindung bezieht sich auf ein knieförmiges Übergangs stück zum Verbinden eines unter Putz verlegten Kunststoff rohres mit einer metallischen Armatur, wobei das Übergangs stück zwei zueinander achsnormale, durch einen Krümmer verbundene Stutzen bildet, von denen der eine zum Einschwei ßen des Kunststoffrohres dient und der andere ein Gewinde zum Einschrauben der Armatur aufweist.The invention relates to a knee-shaped transition piece for connecting a plastered plastic pipe with a metallic fitting, the transition piece two to each other normal to the axis, through a manifold connected connecting pieces, one of which is for welding The plastic tube is used and the other is a thread for screwing in the valve.
Bei bekannten Übergangsstücken dieser Art (AT-PS 378 390) ist das Verbindungsstück im wesentlichen bloß als Winkel stück ausgebildet, d. h. der die beiden Stutzen verbindende Krümmer erstreckt sich lediglich über 90°. Ist in dem die Armatur aufnehmenden Stutzen eine Gewindebüchse einge spritzt, die aus einem gegenüber dem Muffenwerkstoff fe sterem Material besteht, z. B. aus Metall (AT-PS 378 390), oder aus einem besonderen Polymer (AT-PS 388 605), 50 muß hinter der Büchse noch eine gewisse Menge Kunststoff des Übergangsstückes vorhanden sein, bevor der Krümmer ansetzt. Im übrigen aber ergibt sich, ob eine Gewindebüchse einge setzt ist oder nicht oder ob das ganze Verbindungsstück überhaupt aus einem festeren Kunststoff besteht und nur für die Schweißverbindung mit dem Leitungsrohr mit einer Muffe aus weniger festem Werkstoff versehen ist oder ob es sich schließlich um ein Übergangsstück aus üblichem Kunststoffmaterial ohne Besonderheiten handelt, ein be trächtlicher Abstand zwischen der Stirnfläche des die Ar matur aufnehmenden Stutzens und der Achse des Stutzens für das Kunststoffrohr, weil der Radius des sich über 90° erstreckenden Krümmers eine bestimmte Größe aufweisen muß. Dieser Abstand hat aber zur Folge, daß der Schlitz im Putz od. dgl. zur Verlegung des Kunststoffrohres eine ziemliche Tiefe aufweisen muß, die einen erhöhten Arbeitsaufwand und auch einen entsprechenden Materialbedarf des Verputzes zum Schließen des Schlitzes bedingt.In known transition pieces of this type (AT-PS 378 390) the connector is essentially merely an angle piece formed, d. H. the one connecting the two sockets Manifold only extends over 90 °. In which is the Valve-receiving connector inserted a threaded sleeve sprays out of a compared to the sleeve material fe stere material consists, for. B. made of metal (AT-PS 378 390), or from a special polymer (AT-PS 388 605), 50 must behind the rifle a certain amount of plastic Transition piece must be present before the manifold starts. For the rest, it follows whether a threaded bush is turned on sets or not or whether the whole connector consists of a firmer plastic at all and only for the welded connection with the conduit with a Is made of less strong material or whether it is ultimately a transition piece from the usual Plastic material deals with no special features, a be pregnant distance between the face of the ar matur receiving nozzle and the axis of the nozzle for the plastic pipe because the radius of the pipe is over 90 ° extending elbow must have a certain size. However, this distance means that the slot in the plaster od. The like for laying the plastic pipe quite a bit Must have depth, the increased workload and also a corresponding material requirement of the plaster conditionally to close the slot.
Somit liegt der Erfindung die Aufgabe zugrunde, diesen Mangel zu beseitigen und ein Übergangsstück der eingangs geschilderten Art zu schaffen, bei dessen Verwendung das Kunststoffrohr in einen beträchtlich seichteren Schlitz verlegt werden kann.The invention is therefore based on the object Eliminate deficiency and a transition piece of the beginning to create described type, the use of which Plastic pipe in a considerably shallower slot can be relocated.
Die Erfindung löst die gestellte Aufgabe dadurch, daß sich der Krümmer im Sinne einer Verlagerung des das Kunststoff rohr aufnehmenden Stutzens zur Stirnfläche des anderen Stutzens hin über mehr als 90° erstreckt und etwa S-förmig ausgebildet ist.The invention solves the problem in that the manifold in the sense of a shift of the plastic pipe-receiving socket to the end face of the other Neck extends over more than 90 ° and approximately S-shaped is trained.
Auf diese Weise wird der Abstand zwischen der Stirnfläche des die Armatur aufnehmenden Stutzens und der Achse des einzuschweißenden Kunststoffrohres auf ein Minimum redu ziert, so daß dann auch der Schlitz bzw. die Nut zur Verlegung des Kunststoffrohres eine beträchtlich geringere Tiefe aufzuweisen braucht, womit die gewünschte Arbeits- und Materialeinsparung erreicht ist. Die gegebenenfalls notwendige Ausnehmungserweiterung im Bereich des Übergangs stückes ist bedeutungslos, da es sich dabei, wie gesagt, nur um einen verhältnismäßig kleinen Bereich der Wand od. dgl. handelt. In this way, the distance between the end face of the fitting receiving the fitting and the axis of the to be welded plastic pipe to a minimum adorns, so that then the slot or the groove Laying the plastic pipe is considerably less Needs to show depth, with which the desired work and material saving is achieved. The possibly Necessary widening in the transition area piece is meaningless because, as I said, or the like only around a relatively small area of the wall. acts.
In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und zwar zeigenIn the drawing, the subject of the invention is in one Embodiment shown, and show
Fig. 1 ein Übergangsstück in Axialschnitt und Fig. 1 is a transition piece in axial section and
Fig. 2 in Stirnansicht. Fig. 2 in front view.
Das knieförmige Übergangsstück aus Kunststoff weist einen mit einem Gewindeeinsatz 1 versehenen Stutzen 2 zum Ein schrauben einer Armatur und einen Stutzen 3 zum Einschwei ßen eines unter Putz verlegten Kunststoffrohres auf. Die beiden Stutzen 2, 3 sind durch einen Krümmer 4 verbunden, der sich, wie ersichtlich, über weit mehr als 90° erstreckt und etwa S-förmig ausgebildet ist. Bei einem Übergangsstück herkömmlicher Ausbildung würde die Achse a₁ des Stutzens 3 nach der 90gradigen Krümmung gerade weiterverlaufen, so daß sich zwischen der Achse a₁ und der Achse a₂ des Stutzens 3 der erfindungsgemäßen Ausbildung ein Abstand 5 ergibt, der zu der gewünschten seichteren Ausbildung der Schlitze oder Nuten zur Rohrverlegung führt. Mit 6 sind Ansätze am Krümmer 4 des Übergangsstückes bezeichnet, die zur Schraubbefestigung dieses Stückes dienen.The knee-shaped transition piece made of plastic has a socket 2 provided with a threaded insert 1 for screwing a fitting and a socket 3 for welding a plastic pipe laid under plaster. The two connecting pieces 2 , 3 are connected by an elbow 4 , which, as can be seen, extends over much more than 90 ° and is approximately S-shaped. In a transition piece of conventional design would axis a₁ of the nozzle 3 after 90gradigen curvature just extend further so that a₁ between the axis and the axis A₂ of the neck 3 of the training according to the invention, a distance 5 results in leading to the desired shallower formation of the slits or Grooves leads to pipe laying. With 6 approaches to the manifold 4 of the transition piece are designated, which serve to screw this piece.
