Description

Zur Herstellung der Anschlüsse von Hausleitungen an Hauptrohre des Gas- und Wasserleitungsnetzes werden Anbohr-Rohrschellen benutzt, die mit Hilfe von Stahlbändern, Bügeln oder Ketten, die um das Hauptrohr geschlungen, gehalten werden. Diese Bänder, Bügel oder Ketten besitzen an ihren Enden Gewindebolzen, mit denen sie durch an der Rohrschelle verlagerte Haltemuttern hin,durchgeschraubt sind, so daß .durch Anziehen der Muttern die Bügel od. dgl. festgezogen werden können. Alle diese Teile liegen nach der Fertigstellung des Anschlusses frei im Erdreich und sind den zerstörenden Einwirkungen der Erdeinflüsse ausgesetzt. Durch das Verrosten des Gewindes bzw. durch das Festrosten der Muttern auf dem Gewinde wird ein späteres Nachstellen oder der Wiederausbau der Rohrschelle unmöglich gemacht. Auch kann durch das Abrosten der verhältnismäßig dünnen Gewindegänge mit der Zeit - ein selbständiges Lösen der Verbindung zwischen Hauptrohr und Rohrschelle eintreten, das zu gefährlichen Gas- oder Wasserausbrüchen führen kann.For making connections from house lines to the main pipes of the Gas and water pipeline network tapping pipe clamps are used, which with the help held by steel bands, brackets or chains that are looped around the main pipe will. These bands, brackets or chains have threaded bolts at their ends which they are screwed through by means of retaining nuts displaced on the pipe clamp, so that .by tightening the nuts, the bracket or the like can be tightened. All these parts are exposed in the ground after the connection has been completed and are exposed to the destructive effects of the earth's influences. By rusting of the thread or the rusting of the nuts on the thread is a later Adjustment or removal of the pipe clamp made impossible. Also can through the rusting of the relatively thin threads over time - an independent one Loosening of the connection between the main pipe and the pipe clamp can be dangerous Gas or water outbreaks.

Die Erfindung beseitigt diese Nachteile und besteht darin, daß die Gewindebolzen der Haltebänder, Bügel oder Ketten in eine Hülsenmutter eingeschraubt sind, die an ihrem unteren Rande eine Dichtung aus Gummi od. dgl. trägt. Auf diese Weise ist der empfindliche Teil der Halterung gegen äußere Einflüsse geschützt.The invention overcomes these disadvantages and consists in that the The threaded bolts of the straps, brackets or chains are screwed into a sleeve nut are, which od at its lower edge a seal made of rubber. The like. Wears. To this The sensitive part of the bracket is protected against external influences.

Um das Gewinde innerhalb der Mutter stets nur in axialer Richtung, also gleichmäßig, zu belasten und damit eine einseitrige Beanspruchung des Gewindes bzw. eine Biegebeanspruchung des Gewindebolzens zu vermeiden, ist es zweckmäßig, die Hülsenmutter an den Tragarmen der Rohrschelle in halbzylinderförmige Zwischenstücke zu verlagern,, die in entsprechend gestaltete Auflager der Tragarme der Rohrschelle schwenkbar eingelegt sind. Schalenförmige Auflager für Zwischenstücke in Form einer Kugelkalotte sind für diese Zwecke- an sich bekannt; die halbzylinderförrnigen Zwischenstücke besitzen jedoch :durch größere Auflageflächen bessere Lagerung und auch geringere Flächenpressung.To keep the thread inside the nut only in the axial direction, So evenly, to load and thus a one-sided stress on the thread or to avoid bending stress on the threaded bolt, it is advisable to the sleeve nut on the support arms of the pipe clamp in semi-cylindrical spacers to relocate, which in appropriately designed supports of the support arms of the pipe clamp are pivotably inserted. Shell-shaped supports for intermediate pieces in the form of a Spherical caps are known per se for this purpose; the semi-cylindrical spacers have, however: better storage due to larger contact surfaces and also less Surface pressure.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

Abb. i zeigt :ein Hauptrohr mit Anbohr-Rohrschelle; Abb.2 zeigt die Hülsenmutter mit Gewindebolzen gemäß der Erfindung in vergrößertem Maßstab. -Gemäß Abb. i wird die Anbohr-Rohrschelle i auf dem Hauptrohr 2 mit Hilfe,des Bügels 3 gehalten..-Der Bügel 3 besitzt an seinen Enden Gewindebolzen q., mit denen sie in die einseitig geschlossene Hülsenmutter 5 eingeschraubt sind. Die Hülsenmutter 5 besitzt an ihrem unteren Rande eine Dichtung G aus Gummi od. dgl., an der der gewindelose Teildes Bolzens" q. zur Anlage kommt und damit eine Abdichtung nach außen gebildet wird. Die Hülsenmutter- 5 wird von dem halbzylinderförmigen Zwischenstück 7 gehalten, das in einer entsprechend geformten Mulde des Tragarmes 8 der Rohrschelle i eingelegt ist. Durch Anziehen der Hülsenmutter 5 kann der .Bügel angespannt werden. Das Gewinde des Gewindebolzens- q. ist innerhalb der Hülsenmutter 5 gegen äußere Einflüsse geschützt.Fig. I shows: a main pipe with a tapping pipe clamp; Fig.2 shows the Sleeve nut with threaded bolt according to the invention on an enlarged scale. -According to Fig. I is the tapping pipe clamp i on the main pipe 2 with the help of the bracket 3 held ..- The bracket 3 has threaded bolts q. at its ends, with which it is in the sleeve nut 5, which is closed on one side, is screwed in. The sleeve nut 5 has a seal G made of rubber or the like at its lower edge, on which the threadless Part of the bolt "q. Comes to rest and thus forms a seal to the outside will. The sleeve nut 5 is held by the semi-cylindrical intermediate piece 7, which is inserted into a correspondingly shaped recess of the support arm 8 of the pipe clamp i is. The bracket can be tightened by tightening the sleeve nut 5. The thread of the threaded bolt q. is protected against external influences within the sleeve nut 5.
