Abstract

The invention relates to a railway sleeper according to Patent Application P 3345858.8, which is reinforced by a shaped steel plate.

Description

In der Hauptanmeldung P 33 45 858.8 werden mitIn the main application P 33 45 858.8 with

Holzmehl gefüllte Formmassen aus Epoxyharzen oder vulkanisierbaren Gummimischungen und deren Verwendung zur Herstellung von Bahnschwellen beansprucht.Wood flour-filled molding compounds made from epoxy resins or vulcanizable Rubber compounds and their use for the production of railway sleepers claimed.

Aus diese Formmassen werden zu diesem Zweck Körper mit tragförmiger Ausgestaltung hergestellt, die die Oberseite und Seitenteile eines Holzkerns umhüllen.For this purpose, these molding compounds are used to create bodies with a load-bearing shape Design made that encase the top and side parts of a wood core.

Es wurde nun gefunden, daß die Stabilität diser Bahnachwelle datiurch deutlich verbessert wircl, daß zwischen H@lzkern (4) und Formkörper (5) eine geformte Stahlplatte (6) eingefügt ist.It has now been found that the stability of this railway shaft is by Wircl significantly improved that between the wooden core (4) and the shaped body (5) a shaped Steel plate (6) is inserted.

Die Dicke der Stahlplatte (6) beläuft sich in Abhängigkeit von der zu erwartenden Belastung auf o,? bis 0,9 mm.The thickness of the steel plate (6) depends on the expected load on o ,? up to 0.9 mm.

T)er Formkörper und der Holzkern werden über bzw.T) he shaped body and the wood core are over or

in die geformte Stahlplatte hineingepreßt, geSebenenfalis unter Zusatz von geeigneten die Verklebung und Haftung fördernden Materialien.pressed into the formed steel plate, geSebenenfalis with addition of suitable materials that promote bonding and adhesion.

In Abb. 1 ist eine beispielhafte Ausführung wiedergegeben.In Fig. 1 an exemplary embodiment is shown.
