  Bei Kunsteisbahnen zum Beispiel werden  die zur Leitung des Kältemittels dienenden  Rohrstücke bekanntlich in Längen von<B>6, 8,</B>  <B>10,</B> ja sogar bis zu<B>15</B> Metern geliefert. Die  totale Differenz. der Temperatur von Kühl  solen während<U>des</U> Betriebes der Anlage, die  bis zu -20<B>0 C</B> betragen kann, und der  Temperatur, welche im Sommer bei stillie  gendem Betriebe in heissen Tagen in der  Betonschicht     bezw.    in der     Berohrung    dersel  ben bis zu<B>50 0</B> und mehr erreichen kann,  beträgt<B>70 '</B>     C    und mehr, wobei ohne weiteres  grosse Spannungen durch die verschiedenen  Wärmeausdehnungen auftreten können.  



  Im eingebetteten Zustande der Rohre<B>A</B>  und B nehmen nun die     Verankerungsrippen     a     bezw.    a'     bezw.        a'    die aus der ungleichen  Ausdehnung des     Rohrmaterials    und der     Beton-          schiebt    sich ergebenden Spannungskräfte auf,  wodurch die Verbindungsstellen zweier Rohr  enden geschont und Risse an denselben ver  mieden werden.  



  Bei Verwendung von sehr langen Rohr  stücken ohne Stossverbindung ist es zweck  mässig, 'ausser den     Verankerungsrippen    an den  Enden in der Nähe der Stossverbindungen  auch noch im Mittelteil des Rohres eine oder    mehrere     derartigerVerankerungen    vorzusehen,  um Ausdehnungsdifferenzen zwischen Beton  und Rohr noch weiter entgegenzutreten.

      for example by soldering or welding on the mutually facing end parts of the tubes <B> A </B> and B are attached.



  In the case of artificial ice rinks, for example, the pipe sections used to convey the refrigerant are known to be supplied in lengths of <B> 6, 8, </B> <B> 10, </B> and even up to <B> 15 </B> meters . The total difference. the temperature of cooling brines during <U> operation </U> of the system, which can be as low as -20 <B> 0 C </B>, and the temperature which in summer when the plant is shut down on hot days the concrete layer respectively. in the tubing which can reach up to <B> 50 0 </B> and more is <B> 70 '</B> C and more, with great stresses easily occurring due to the various thermal expansions.



  In the embedded state of the tubes <B> A </B> and B, the anchoring ribs a or. a 'resp. a 'the tension forces resulting from the unequal expansion of the pipe material and the concrete are displaced, whereby the connection points of two pipe ends are spared and cracks at the same are avoided.



  When using very long pipe sections without a butt joint, it is advisable to provide one or more such anchors in the middle part of the pipe in addition to the anchoring ribs at the ends near the butt joints, in order to counteract expansion differences between concrete and pipe even further.
