Abstract

The solid part forming the heel 8 of the intermediate insulating component is recessed with at least two cells 15 emerging on the upper face and located on either side of the hole 16 through which the sleeper screw passes. This reduction in volume of the intermediate insulating component allows rapid plastification of its constituent material and enables its cost of manufacture to be reduced without modifying its compressive strength properties.

Description

Perfectionnements aux dispositifs d'assemblage élastique des rails sur leurs traverses.Improvements to the elastic assembly devices of the rails on their sleepers.

La présente invention concerne les dispositifs d'assemblage élastique des rails sur leurs traverses, du genre de ceux comprenant une pièce isolante intercalaire, en butée contre la semelle du rail et contre un épaulement de la traverse et retenue par une lame à ressort, tandis qu'un moyen de serrage fixe lesdits éléments sur la traverse. The present invention relates to devices for elastic assembly of the rails on their crosspieces, of the type comprising those of an insulating intermediate piece, in abutment against the sole of the rail and against a shoulder of the crosspiece and retained by a spring blade, while 'A clamping means fixes said elements on the crosspiece.

Le brevet FR A 2411920 et son certificat d'addition N0 2 426 770 décrivent un dispositif analogue dont l'interca-.  The patent FR A 2411920 and its certificate of addition N0 2 426 770 describe a similar device including the interca-.

laire à la forme générale d'un trapèze dont le plus grande base est disposée au-dessus de la semelle du rail, tandis que la partie opposée, après le talon, s'appuie sur la traverse et comporte une gorge creusée sur la face supérieure dans laquelle bute l'extrémité de forme correspondante d'une lameressort; lesdites pièces étant percées chacune d'une ouverture qui coincide avec la précédente, destinée au passage d'un boulon ancré dans la traverse sur lequel est vissé un écrou serrant la lame élastique sur l'intercalaire.laire with the general shape of a trapezoid, the largest base of which is arranged above the sole of the rail, while the opposite part, after the heel, rests on the cross-member and has a groove hollowed out on the upper face in which the correspondingly shaped end of a spring spring abuts; said parts being each pierced with an opening which coincides with the previous one, intended for the passage of a bolt anchored in the crosspiece on which is screwed a nut tightening the elastic blade on the interlayer.

Cette butée intercalaire est généralement moulée en polyamide, sa forme est massive, son coQt est élevé et son obtention par moulage est difficile
Le but de l'invention est de fournir une pièce allégée autorisant une plastification rapide et concrète du matériau de base et par conséquent, permettant l'abaissement de son prix de revient, sans pour autant modifier ses caractéristiques de résistance à la compression.
This intermediate stop is generally molded in polyamide, its shape is massive, its cost is high and it is difficult to obtain it by molding.
The object of the invention is to provide a lightened piece allowing rapid and concrete plasticization of the base material and therefore allowing the lowering of its cost price, without however modifying its compressive strength characteristics.

Suivant une première caractéristique de l'invention, on allège les parties massives de l'intercalaire en creusant sa face supérieure pour conserver au talon travaillant à la compression une section maximum. According to a first characteristic of the invention, the massive parts of the interlayer are lightened by digging its upper face to keep the heel working at compression a maximum section.

Une autre caractéristique consiste à égaliser les épaisseurs de l'intercalaire pour que la règle de constante qui fait loi dans les pièces thermo-plastiques moulées s'applique.  Another characteristic consists in equalizing the thicknesses of the interlayer so that the rule of constant which prevails in the molded thermoplastic parts applies.

Sous une forme d'exécution préférentielle de l'intercalaire, on réserve au moulage au moins deux alvéoles situés au niveau du talon de butée de la semelle du rail et débouchant sur la face supérieure de part et d'autre du trou de passage du boulon ou du tire-fond destiné au serrage de la lame ressort de retenue
Sous une forme d'exécution de l'intercalaire on réalise le talon de butée de manière que sa face inférieure soit concave pour augmenter sa tenue à la compression et éventellement on supprime son aile d'appui ceté rail.
In a preferred embodiment of the interlayer, there are reserved for molding at least two cells located at the abutment heel of the sole of the rail and opening onto the upper face on either side of the bolt through hole or the lag screw for tightening the spring retaining blade
In one embodiment of the interlayer, the abutment heel is produced so that its lower face is concave to increase its resistance to compression and, optionally, its support wing is removed.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant plusieurs modes d'exécution. The invention is set out below in more detail with the aid of drawings representing several embodiments.

La figure 1 représente en coupe un assemblage élastique équipé d'un intercalaire suivant l'invention. Figure 1 shows in section an elastic assembly equipped with a spacer according to the invention.

La figure 2 montre en coupe d'élévation un intercalaire selon 1 'invention;

La figure 5 en est une vue en plan par-dessus. Figure 5 is a plan view from above.

La figure 6 montre une autre variante de l'intercalaire, vue en coupe d'élévation. Figure 6 shows another variant of the insert, seen in elevation section.

La figure 7 en est une vue en plan par-dessus. Figure 7 is a plan view from above.

Comme le montre la figure 1, le dispositif élastique de fixation d'un rail 1 sur une traverse 2 est constitué, à la manière connue, par un intercalaire 3 en forme de trapèze sur lequel vient s'appuyer une lame élastique 4 serrée contre ledit intercalaire au moyen de la tête 5 d'un tirefond 6 prenant écrou dans une gaine plastique 7 noyée dans la traverse 2 en béton par exemple, mais non exclusivement. As shown in Figure 1, the elastic device for fixing a rail 1 on a cross member 2 is constituted, in the known manner, by a spacer 3 in the form of a trapezoid on which abuts an elastic blade 4 clamped against said interlayer by means of the head 5 of a lag screw 6 taking nut in a plastic sheath 7 embedded in the cross member 2 of concrete for example, but not exclusively.

L'intercalaire 3 forme un talon 8 qui vient en butée d'un côté contre la semelle 9 du rail 1 et de l'autre côté contre un épaulement 10 de la traverse 2 et deux ailes dont celles 3a vient reposer sur la semelle 9 du rail 1 et dont l'autre 3b épouse l'épaulement 10. La face supérieure de l'aile 3b de l'intercalaire comporte une gorge 11 fermée par deux butées 12 et dans laquelle vient s'insérer l'extrémité 15, de forme correspondante, de la lame élastique 4.  The interlayer 3 forms a heel 8 which abuts on one side against the sole 9 of the rail 1 and on the other side against a shoulder 10 of the cross member 2 and two wings of which those 3a comes to rest on the sole 9 of the rail 1 and the other 3b of which follows the shoulder 10. The upper face of the wing 3b of the interlayer has a groove 11 closed by two stops 12 and into which the end 15 is inserted, of corresponding shape , of the elastic blade 4.

Les figures 2 et 3 montrent un intercalaire allégé selon l'invention, dont le talon 8 est creusé de deux alvéoles 15 situés de part et d'autre du trou 16 de passage du tirefond 6, alvéoles qui débouchent sur la face supérieure de ladite pièce et qui sont venus de moulage. Figures 2 and 3 show a lightweight insert according to the invention, the heel 8 is hollowed out of two cells 15 located on either side of the hole 16 for passage of the lag screw 6, cells which open on the upper face of said piece and who came from molding.

Les figures 4 et 5 montrent une variante d'intercalaire allégé selon l'invention. Comme l'indique le pointillé 17 de la figure 4, la face supérieure est évidée et le talon 8 est également creusé de deux alvéoles 18 qui entoure le trou 16 de passage du tirefond 6. Figures 4 and 5 show a variant of lightened interlayer according to the invention. As indicated by the dotted line 17 in FIG. 4, the upper face is hollowed out and the heel 8 is also hollowed out by two cells 18 which surround the hole 16 for the passage of the lag screw 6.

Les figures 6 et 7 représentent une autre variante d'intercalaire allégé selon l'invention. I1 est creusé, comme les précédents, d'alvéoles 19 situés de part et d'autre du trou 16 de passage du tirefond 6 et débouchent à la partie supérieure du talon 8. Figures 6 and 7 show another variant of lightweight insert according to the invention. I1 is hollowed out, like the previous ones, with cells 19 located on either side of the hole 16 for the passage of the lag screw 6 and lead to the upper part of the heel 8.

Comme le montre plus particulièrement la figure 6, la face supérieure 20 et la face inférieure 21 du talon 8 de l'intercalaire sont concaves pour augmenter la tenue à la compression qui s'exerce-de part et d'autre du talon selon les flèches A-A. As shown more particularly in FIG. 6, the upper face 20 and the lower face 21 of the heel 8 of the interlayer are concave to increase the resistance to compression which is exerted on either side of the heel according to the arrows AA.

Dans cette variante d'intercalaire, on peut supprimer l'aile 3a qui repose normalement sur la semelle 9 du rail. In this variant of the insert, the wing 3a which normally rests on the sole 9 of the rail can be omitted.

Tous les alvéoles 15,18 et 19 creusant les talons 8 des intercalaires montrés figures 3 à 7, peuvent être munis de nervures transversales non représentées.  All the cells 15, 18 and 19 digging the heels 8 of the spacers shown in FIGS. 3 to 7, can be provided with transverse ribs, not shown.
