Description

Rohrverbindung für gleichachsig liegende und sich im stumpfen Stoß berührende Rohre, insbesondere für Rohre mit rechteckigem Querschnitt Die Erfindung geht aus von einer Rohrverbindung für gleichachsig liegende und sich im stumpfen Stoß berührende Rohre, insbesondere für Rohre mit rechteckigem Querschnitt, mit zwei innerhalb des Rohrhohlraums liegenden Klemmelementen, die durch senkrecht zur Rohrachse gerichtete Schrauben -auseinander und gegen die Innenwände der zu verbindenden Rohre gepreßt sind.Pipe connection for coaxial and butt joint contacting pipes, in particular for pipes with a rectangular cross-section. The invention assumes a pipe connection for equiaxed and obtuse ones Butt contacting pipes, in particular for pipes with a rectangular cross-section, with two clamping elements lying within the tube cavity, which are perpendicular to the Screws directed towards each other and against the inner walls of the pipe axis to be connected Pipes are pressed.

Bei bekannten Rohrverbindungen der soeben genannten Art sind die Rohrverbindungsteile weitgehend an den Durchmesser bzw. die Kontur der zu verbindenden Rohre gebunden, so daß also dieselben Verbindungsteile nicht in einfacher Weise für verschiedene Rohrdurchmesser bzw. Rohrquerschnitte verwendbar sind. Außerdem können bei diesen Rohrverbindungen die Klemmelemente sich nicht unabhängig voneinander auf die Rohrwände einstellen. Bei Rohren mit rechteckigem Querschnitt könnte bei diesen bekannten Rohrverbindungen nicht erreicht werden, daß sich die Druckflächen in den Ecken des Rohrquerschnittes anlegen.In known pipe connections of the type just mentioned, the pipe connection parts are largely tied to the diameter or the contour of the pipes to be connected, so that the same connecting parts are not easily used for different ones Pipe diameter or pipe cross-sections can be used. You can also use these Pipe connections the clamping elements are not independent of one another on the pipe walls to adjust. In the case of pipes with a rectangular cross-section, these could be known Pipe connections are not achieved that the pressure surfaces in the corners of the Create pipe cross-section.

Gegenüber diesem Bekannten besteht die Aufgabe der Erfindung darin, Rohrverbindungen der im ersten Absatz dieser Beschreibung dargestellten Art. insoweit zu verbessern, daß mit einfachen Mitteln erreicht ist, daß die Rohrverbindungsteile für verschiedene Rohrdurchmesser und Rohrquerschnitte angewandt werden können.Compared to this known, the object of the invention is Pipe connections of the type shown in the first paragraph of this description. Insofar to improve that is achieved by simple means that the pipe connection parts can be used for different pipe diameters and pipe cross-sections.

Zur Lösung dieser Aufgabe ist vorgesehen, däß die Klemmelemente mehrere voneinander unabhängige Stäbe sind, die durch Schrauben über Druckstücke gegen die Innenwände der zu verbindenden Rohre gepreßt sind.To solve this problem it is provided that the clamping elements have several are mutually independent rods that are screwed against pressure pieces against the Inner walls of the pipes to be connected are pressed.

Als für die Aufgabenlösung vorteilhafte und förderliche Weiterbildungen sind weitere Merkmale den am Schluß dieser Beschreibung angeführten Unteransprüchen 2 und 3 zu entnehmen.As further training that is advantageous and conducive to solving tasks are further features of the subclaims listed at the end of this description 2 and 3.

Durch die Erfindung ist insofern ein technischer Fortschritt erreicht, als mit einfachen Mitteln ermöglicht wird, die gleichen Verbindungsteile bei verschiedenen Rohrdurchmessern und Rohrquerschnitten anzuwenden. Die Verbindungsstäbe können sich unabhängig voneinander auf die Rohrwände einstellen und ergeben somit eine gute Zentrierungsmöglichkeit und eine gleichmäßige Anpressung an der Verbindung. Bei Rohren mit rechteckigem Querschnitt können sich die Stäbe in den Ecken des Rohres anlegen und geben damit auch bei solchen Rohrverbindungen eine sehr gute Verbindungsmöglichkeit.A technical advance is achieved by the invention, than is made possible by simple means, the same connecting parts in different Pipe diameters and pipe cross-sections to be used. The connecting rods can adjust independently of each other on the pipe walls and thus result in a good Centering option and even pressure on the connection. at Pipes with a rectangular cross-section can have the rods in the corners of the pipe create and thus give a very good connection option even with such pipe connections.

Die Erfindung wird an Hand eines Ausführungsbeispiels in der Zeichnung näher erläutert. Hierbei zeigt A b b. 1 einen Querschnitt durch die Rohrverbindung für quadratische Rohre nach der Linie 1-I der Abb.2, A b b. 2 und 3 Schnitte längs der Linie II-11 und III-III der A b b. 1 und A b b. 4 ein Anwendungsbeispiel für die Rohrverbindung.The invention is illustrated using an exemplary embodiment in the drawing explained in more detail. Here A b shows b. 1 shows a cross section through the pipe connection for square tubes according to the line 1-I of Figure 2, A b b. 2 and 3 cuts lengthways the line II-11 and III-III of A b b. 1 and A b b. 4 an application example for the pipe connection.

Aus der Zeichnung ist die Rohrverbindung für gleichachsig liegende und sich im stumpfen Stoß berührende Rohre 1, 2 zu ersehen. Wie die A b b. 1 zeigt, können es rechteckige, insbesondere quadratische Rohre sein. Zur Verbindung sind mehrere voneinander unabhängige Stäbe 3 bis 6 vorgesehen, die von den Schrauben 10 über Druckstücke 7, 8 gegen die Innenwände der zu verbindenden Rohre 1, 2 gepreßt sind. Die vier Stäbe 3 bis 6 können kreisrunden Querschnitt aufweisen, wobei bei einer Verbindung für rechteckige Rohre (vgl. insbesondere A b b. 1) ein kreisrunder Querschnitt der Stäbe 3 bis 6 vorgesehen ist. Hierbei liegt in jeder Ecke des Rohrquerschnitts ein Stab 3 bis 6. Die Druckstücke 7, 8 weisen schräg zu den Rohrwänden liegende Anlageflächen 9 für die Stäbe auf.From the drawing is the pipe connection for equiaxed and pipes 1, 2 touching each other in the butt joint can be seen. Like the A b b. 1 shows it can be rectangular, especially square tubes. To connect are several independent rods 3 to 6 provided by the screws 10 pressed via pressure pieces 7, 8 against the inner walls of the pipes 1, 2 to be connected are. The four rods 3 to 6 can have a circular cross-section, with a connection for rectangular pipes (cf. in particular A b b. 1) a circular one Cross section of the rods 3 to 6 is provided. Here lies in every corner of the pipe cross-section a rod 3 to 6. The pressure pieces 7, 8 point obliquely to the pipe walls Contact surfaces 9 for the rods.
