Abstract

The concrete railway sleeper comprises spacing plates (34), which are held in position by integral rods (35) cast into the body of the sleeper. Once the concrete has hardened, rail supports (36) of steel are welded to the spacing plates. A layer of insulating material (39) is positioned between the spacing plates and the body of the sleeper to protect the concrete during welding of the rail supports.

Description

Le brevet principal a pour objet une traverse en béton armé pour appareils de voie, pourvue d'une rainure centrale longitudinale ou d'une zone centrale longitudinale facile à usiner pour la fixation des attaches de rails, cette rainure étant, de préférence, située dans la moitié supérieure de la traverse. The main patent relates to a reinforced concrete cross member for switches and crossings, provided with a longitudinal central groove or with a longitudinal central zone which is easy to machine for fixing the rail fasteners, this groove preferably being located in the upper half of the crosspiece.

La présente demande de certificat d'addition a pour objet une variante de réalisation de l'invention. The present application for a certificate of addition relates to an alternative embodiment of the invention.

Conformément à cette variante de réalisation, la traverse en béton armé est munie de platines de répartition pourvues de tiges de scellement soudées, et sur lesquelles sont placées et soudées, après coulaqe et durcissement du béton, des selles en acier soudable pour la fixation des rails, ou autres appareils de voies. In accordance with this alternative embodiment, the reinforced concrete cross member is provided with distribution plates provided with welded sealing rods, and on which are placed and welded, after pouring and hardening of the concrete, weldable steel saddles for fixing the rails. , or other track devices.

Selon une autre caractéristique de l'invention, entre les platines de répartition et le béton est interposé un maté riaV intercalaire isolant protégeant ledit béton contre une montée en température trop importante lors du soudage des selles. According to another characteristic of the invention, between the distribution plates and the concrete is interposed an insulating interlayer material protecting said concrete against too high a temperature rise during welding of the saddles.

L'invention sera mieux comprise grâce à la description ci-après ! qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dans lequel la figure 1 est une vue en plan d'une traverse conforme à l'invention, et la figure 2 est une vue en coupe de la traverse de la figure 1. The invention will be better understood thanks to the description below! which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawing, in which FIG. 1 is a plan view of a crosspiece according to the invention, and the Figure 2 is a sectional view of the cross member of Figure 1.

Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 et 2 du dessin annexé, la traverse en béton armé 1 est munie de platines de répartition 34, qui sont pourvues de tiges de scellement 35 soudées, et sur ces platines 34 sont placées et soudées des selles 36 en acier soudable destinées à la fixation des rails 37 ou d'autres appareils de voies. According to the invention, and as shown more particularly, by way of example, Figures 1 and 2 of the accompanying drawing, the reinforced concrete cross member 1 is provided with distribution plates 34, which are provided with sealing rods 35 welded, and on these plates 34 are placed and welded saddles 36 of weldable steel intended for fixing the rails 37 or other track devices.

Les platines de répartition 34 constituent des aires planes, qui sont mises à plat au fond du coffrage avec les tiges de scellement 35 préalablement soudées tournées vers le haut, lors du bétonnage de la traverse 1. The distribution plates 34 constitute flat areas, which are laid flat at the bottom of the formwork with the sealing rods 35 previously welded facing upwards, during the concreting of the cross member 1.

Après durcissement du béton, les selles 36 en acier soudable pour l'attache indirecte des rails 37, qui peuvent être, par exemple, des selles à nervures, sont placées suivant les besoins sur les platines 34 et soudées sur ces dernières au moyen de cordons de soudure 38. After the concrete has hardened, the saddles 36 of weldable steel for the indirect attachment of the rails 37, which can be, for example, ribbed saddles, are placed as required on the plates 34 and welded to the latter by means of cords solder 38.

Dans les cas où la qualité du béton fait craindre une diminution importante de sa résistance du fait de l'élévation de température due à la soudure des selles 36 sur les platines 34, il est prévu, conformément à une caractéristique de l'invention, d'intercaler entre les platines 34 et le béton un matériau isolant 39 faisant écran à la montée en température du béton. In the cases where the quality of the concrete makes fear a significant reduction in its resistance due to the rise in temperature due to the welding of the saddles 36 on the plates 34, provision is made, in accordance with a characteristic of the invention, for 'insert between the plates 34 and the concrete an insulating material 39 shielding the rise in temperature of the concrete.

Grâce à l'invention, il est possible d'obtenir une grande souplesse d'utilisation de traverses préparées, ces dernières présentant, pour une longueur donnée, toujours les mêmes platines de répartition, sur lesquelles les selles sont disposées suivant les besoins. Thanks to the invention, it is possible to obtain great flexibility in the use of prepared sleepers, the latter having, for a given length, always the same distribution plates, on which the saddles are arranged as required.

Bien entendu, l'inventionn'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
