Abstract

The clip is for securing plastic pipes to the walls of buildings, and has two semicircular stirrup pieces with protruding flanges clamped together by screws. The stirrup pieces each have on the inside a removable sector-type strip (9, 10). The two ends of the strips fit between the flanges (3, 4) and are secured by the screws (5). Thus the clip normally holds the pipe so that it cannot slide, but removal of the strips allows sliding to compensate for heat expansion etc. The strips can be of plastic, e.g. polyester, and the edges of the stirrup pieces on the inside can be sharp.

Description

  

  
 



   Die Erfindung betrifft eine Rohrschelle mit zwei halbrunden Bügeln mit abstehenden Flanschen, die durch Spannschrauben verbunden sind.



   Zur Befestigung von Kunststoffrohren an Gebäudewänden und -decken werden üblicherweise zwei Arten von Rohrschellen verwendet, nämlich eine sogen. Fixschelle, welche die Aufgabe hat, das Rohr zu halten und in Längsrichtung unverschiebbar zu fixieren und eine sogen. Gleitschelle, welche das Rohr ebenfalls haltern muss, jedoch gestatten soll, dass es sich in Längsrichtung, z. B. unter dem Einfluss von Wärmedehnungen, verschieben kann. Bisher wurden für diese Zwecke für einen bestimmten Rohrdurchmesser jeweils zwei verschiedene Typen von Rohrschellen verwendet, was die Lagerhaltung und den Transport zu den Montageorten erschwerte.



   Die Erfindung bezweckt, eine Rohrschelle zu schaffen, die als Gleitschelle und als Fixschelle verwendet werden kann.



   Die erfindungsgemässe Rohrschelle ist dadurch gekennzeichnet, dass die Bügel im Querschnitt bogenförmig ausgebildet sind, und dass an ihrer konkaven Innenseite je ein im Querschnitt sektorförmiges Band lösbar eingelegt ist, wobei die beiden Enden der Bänder zwischen den Flanschen liegen und von den Spannschrauben gehalten sind.



   In dieser Ausbildung dient die Rohrschelle als Gleitschelle. Soll sie als Fixschelle verwendet werden, wird das eingelegte Band entfernt. Dadurch rücken die Flanschen der beiden Bügel beim Spannen der Spannschrauben näher zusammen und ermöglichen ein Festklemmen der Bügel am zu halternden Kunststoffrohr.



   In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigen:
Fig. 1 eine Vorderansicht einer erfindungsgemässen Rohrschelle und
Fig. 2 eine Seitenansicht derselben.



   Die Rohrschelle weist einen oberen und einen unteren halbrunden Bügel aus Metall 1 bzw. 2 auf. Beide Bügel sind an ihren Enden mit seitlich abstehenden Flanschen 3 bzw. 4 versehen. Die Flansche 3 sind mit einem Loch versehen, während die Flansche 4 je eine Gewindebohrung aufweisen, in die je eine Spannschraube 5 eingeschraubt ist. Am Bügel 2 ist ferner eine Mutter 6 befestigt, deren Gewindebohrung 7 zur Aufnahme eines Tragbolzens dient. Wie aus Fig. 2 ersichtlich ist, sind die Bügel 1, 2 im Querschnitt bogenförmig.



  Die konkaven Innenflächen bilden deshalb mit den Stirnflächen einen spitzen Winkel. Die Innenkanten sind dadurch scharfkantig ausgebildet.



   In die beiden Bügel sind im Querschnitt sektorförmige Kunststoffbänder 9 bzw. 10, z. B. aus Polyester, eingelegt.



  Die Enden der beiden Kunststoffbänder 9, 10 liegen zwischen den Flanschen 3, 4 und weisen Bohrungen auf, durch welche die Spannschrauben 5 durchgreifen.



   In der beschriebenen Ausbildung dient die Rohrschelle als Gleitschelle. Die zwischen den Flanschen 3, 4 liegenden Kunststoffbänder 9, 10 bilden dabei Distanzteile, die verhindern, dass das zu halternde Kunststoffrohr zwischen den Bügeln 1, 2 unverschiebbar festgeklemmt wird.



   Soll die Rohrschelle als Fixschelle verwendet werden, so müssen die Kunststoffbänder 9, 10 entfernt werden. Beim Zusammenschrauben rücken dann die beiden Bügel 1, 2 näher zusammen und klemmen das Kunststoffrohr fest, wobei die scharfen Innenkanten in die Oberfläche des Rohres eindringen und dieses in Längsrichtung unverrückbar festhalten. 



  
 



   The invention relates to a pipe clamp with two semicircular brackets with protruding flanges, which are connected by clamping screws.



   To fasten plastic pipes to building walls and ceilings, two types of pipe clamps are usually used, namely a so-called. Fixing clamp, which has the task of holding the pipe and fixing it so that it cannot be displaced in the longitudinal direction, and a so-called. Sliding clamp, which must also hold the pipe, but should allow it to move in the longitudinal direction, e.g. B. under the influence of thermal expansion, can move. So far, two different types of pipe clamps have been used for a specific pipe diameter for this purpose, which made storage and transport to the assembly sites difficult.



   The aim of the invention is to create a pipe clamp that can be used as a sliding clamp and as a fixed clamp.



   The pipe clamp according to the invention is characterized in that the brackets are arcuate in cross-section, and that a band with a sector-shaped cross-section is detachably inserted on their concave inner side, the two ends of the bands lying between the flanges and held by the tensioning screws.



   In this training the pipe clamp is used as a sliding clamp. If it is to be used as a clamp, the inserted tape is removed. As a result, the flanges of the two brackets move closer together when the tensioning screws are tightened and enable the brackets to be clamped to the plastic pipe to be held.



   An exemplary embodiment of the subject matter of the invention is shown in the drawing. Show it:
1 shows a front view of a pipe clamp according to the invention and
Fig. 2 is a side view of the same.



   The pipe clamp has an upper and a lower semicircular bracket made of metal 1 and 2, respectively. Both brackets are provided with laterally protruding flanges 3 and 4 at their ends. The flanges 3 are provided with a hole, while the flanges 4 each have a threaded hole into which a clamping screw 5 is screwed. A nut 6 is also attached to the bracket 2, the threaded hole 7 of which serves to receive a support bolt. As can be seen from Fig. 2, the brackets 1, 2 are arcuate in cross section.



  The concave inner surfaces therefore form an acute angle with the end surfaces. As a result, the inner edges are sharp-edged.



   In the two brackets are sector-shaped plastic strips 9 and 10, z. B. made of polyester, inserted.



  The ends of the two plastic strips 9, 10 lie between the flanges 3, 4 and have bores through which the clamping screws 5 reach.



   In the training described, the pipe clamp is used as a sliding clamp. The plastic strips 9, 10 lying between the flanges 3, 4 thereby form spacer parts which prevent the plastic pipe to be held from being clamped immovably between the brackets 1, 2.



   If the pipe clamp is to be used as a fixed clamp, the plastic straps 9, 10 must be removed. When screwing together, the two brackets 1, 2 move closer together and clamp the plastic pipe tight, the sharp inner edges penetrating the surface of the pipe and holding it immovably in the longitudinal direction.
