Description

  

      verfahren        zum    Verlegen von     Eisenbahnschwellen        aus        Stahlbeton.       Die Erfindung bezieht sich auf ein Ver  fahren zum Verlegen von Eisenbahnschwellen       aus    Stahlbeton.  



  Schwellen aus Stahlbeton werden im all  gemeinen auf einer     Bettung    von Hartstein  schotter verlegt, und zwar im wesentlichen in  gleicher Weise wie Schwellen aus Stahl oder  Holz. Dabei hat sich gezeigt, dass der Rei  bungswiderstand einer     Stahlbetonschwelle    ver  hältnismässig gering ist. Da beim Überfahren  der Schienen neben den hohen Drücken, die  auf die     Schottersehüttung    ausgeübt werden,  auch horizontale Bewegungen eintreten, ent  steht ein Abrieb des Betons an der Auflager  fläche der Schwelle, der im Lauf der Jahre  erheblich ansteigt und die Lebensdauer der  Schwelle vermindert.  



  Die Erfindung hat sich die Aufgabe ge  stellt, zur Beseitigung dieser Nachteile den  Reibungswiderstand zwischen der Stahlbeton  schwelle und der     Bettung    zu erhöhen und löst  diese Aufgabe dadurch, dass zwischen der       Auflagerfläche    und der     Bettung    eine Klebe  masse angebracht wird.  



  Man kann dabei so vorgehen, dass man eine  geeignete Klebemasse auf die     Auflagerfläche     der Schwelle aufträgt. Zweckmässig geschieht  dies dadurch, dass schon nach erfolgter Her  stellung der Schwelle in der Schwellenfabrik  die untere     Auflagerfläche    mit einer geeigneten  Klebemasse bestrichen wird. Die Wirkungen  können noch verbessert werden, wenn man im  Betonkörper der Schwelle entsprechende Ver  tiefungen anbringt, die eine gute Verankerung    für die aufgestrichene Klebemasse bilden.  Selbstverständlich kann man die Klebemasse  auch aufsprühen, aufspritzen oder sie durch  Eintauchen der Schwellenoberfläche in die  Klebemasse oder in sonst geeigneter     Art    und  Weise auftragen.  



  Es besteht ohne weiteres auch die Möglich  keit, die Klebemasse auf die     Bettung    selbst  aufzutragen, z. B. aufzusprühen.  



  Die Klebemasse muss so beschaffen sein,  dass sie bei allen in Frage kommenden Tem  peraturverhältnissen ihre Wirksamkeit bei  behält. Als Klebemasse sind besonders geeig  net Bitumen, Asphaltmastix oder ähnliche  Massen.



      method of laying reinforced concrete railway sleepers. The invention relates to a Ver drive for laying railway sleepers made of reinforced concrete.



  Reinforced concrete sleepers are generally laid on a bed of hard stone gravel, essentially in the same way as steel or wood sleepers. It has been shown that the frictional resistance of a reinforced concrete sleeper is relatively low. As horizontal movements occur when driving over the rails, in addition to the high pressures exerted on the ballast pile, abrasion of the concrete occurs on the bearing surface of the sleeper, which increases significantly over the years and reduces the life of the sleeper.



  The invention has the task of increasing the frictional resistance between the reinforced concrete threshold and the bedding to eliminate these disadvantages and solves this problem in that an adhesive mass is attached between the support surface and the bedding.



  One can proceed in such a way that one applies a suitable adhesive to the bearing surface of the sleeper. This is expediently done by coating the lower support surface with a suitable adhesive after the sleeper has been manufactured in the sleeper factory. The effects can be further improved if appropriate recesses are made in the concrete body of the threshold, which form good anchoring for the coated adhesive. Of course, the adhesive can also be sprayed on, injected on or applied by dipping the threshold surface into the adhesive or in any other suitable manner.



  There is also the ability to apply the adhesive to the bedding itself, for. B. spray on.



  The adhesive mass must be such that it retains its effectiveness under all relevant temperature conditions. Bitumen, asphalt mastic or similar compounds are particularly suitable as adhesive.
