Description

  

  Ovales Rohr für     Gefrierplatten    künstlicher Eisbahnen.    Die Erfindung betrifft ein ovales Rohr  für Gefrierplatten künstlicher Eisbahnen.  Bereits eine Gefrierplatte von normaler  Grösse weist viele Hunderte solcher von  einem gekühlten Kälteträger, vorzugsweise  gekühlter Salzsohle, durchflossener Platten  rohre auf. Der Preis dieser Rohre spielt in  folgedessen hinsichtlich der Gestehungs  kosten der Gefrierplatte eine wichtige Rolle.  Zweck der Erfindung ist nun, ein ovales  Rohr für     Gefrierplatten    zu schaffen, das bil  lig und in beliebiger Länge     herstellbar    ist.  Zu diesem Behufe ist das ovale Rohr gemäss  der Erfindung aus einem Flacheisen zusam  mengebogen und auf der einen flachen Seite  in der Längsrichtung verschweisst.  



  Auf der Zeichnung ist eine Ausführungs  form des Erfindungsgegenstandes beispiels  weise veranschaulicht, und zwar zeigt die  Figur einen     Querschnitt    durch einen Teil  einer     Gefrierplatte.     



  1 bezeichnet ovale Gefrierrohre der Ge  frierplatte für künstliche     Eisbahnen;    diese  Rohre 1 sind an nicht gezeigte Rohre zum    Zuführen und Abführen von Salzsole an  geschlossen. Jedes Rohr 1 ist gemäss der Er  findung aus einem Flacheisen zusammen  gebogen und auf der einen flachen Seite, wie  bei 8 gezeigt, in der Längsrichtung ver  schweisst. Dadurch, dass die     Verschweissung     auf der flachen Seite und nicht auf einer ab  gerundeten Seite des Rohres 1 vorgenommen  wird, wird durch das Schweissen die Festig  keit des Rohres nicht beeinträchtigt, da an  den betreffenden Stellen die im Rohr vor  kommenden kleinsten     Spannungen    vorhan  den sind.  



  . Der     Vollständigkeit    halber sei noch       erwärhnt,    dass 2 zum Tragen der Gefrier  rohre 1 dienende     Auflegstreifen    bezeichnet.  Diese Streifen 2 sind mit Einpressungen 3  versehen, deren Querschnitt einem Teil des       Querschnittes    der Gefrierrohre 1 entspricht.  so dass diese satt in die Einpressungen 3 zu  liegen kommen, wodurch zugleich die ge  wünschte Distanzierung zwischen den     Ge-          frierrohren    1 gesichert ist.

   Die Auflegestrei  fen 2 sind in nicht gezeigter Weise an einer           tetonplatte    5, die     beispielsweise    aus Zellen  beton bestehen kann, verankert, also in ihrer  Lage gesichert. 6 bezeichnet eine     Sandschüt-          tung,    welche die nicht von den Einpressun  gen 3 umfassten Teile der Gefrierrohre 1 be  deckt.



  Oval tube for freezing plates of artificial ice rinks. The invention relates to an oval tube for freezing plates of artificial ice rinks. Even a normal size freezing plate has many hundreds of such plate tubes through which a cooled refrigerant, preferably a cooled brine, flows. The price of these tubes consequently plays an important role in terms of the production costs of the freezer plate. The purpose of the invention is now to create an oval tube for freezer plates that bil lig and can be produced in any length. For this purpose, the oval tube according to the invention is bent together from a flat iron and welded on one flat side in the longitudinal direction.



  In the drawing, an embodiment of the subject invention is exemplified, namely the figure shows a cross section through part of a freezer plate.



  1 denotes oval freezing tubes of the Ge freezing plate for artificial ice rinks; these pipes 1 are closed to pipes, not shown, for supplying and removing brine. Each tube 1 is bent together according to the invention from a flat iron and welded ver on the one flat side, as shown at 8, in the longitudinal direction. The fact that the welding is carried out on the flat side and not on a rounded side of the tube 1, the Festig speed of the tube is not impaired by the welding, since the smallest tensions in the tube are IN ANY at the points concerned.



  . For the sake of completeness, let it be warmed that 2 denotes hanging strips which are used to carry the freezing tubes 1. These strips 2 are provided with impressions 3, the cross section of which corresponds to a part of the cross section of the freezing tubes 1. so that these come to lie snugly in the indentations 3, which at the same time ensures the desired spacing between the freezing pipes 1.

   The Auflegestrei fen 2 are anchored in a manner not shown on a tetonplatte 5, which may consist of concrete cells, for example, so secured in their position. 6 denotes a bed of sand which covers the parts of the freezing pipes 1 not encompassed by the pressings 3.
