Abstract

Sleepers (2) for a railway track are fitted during production with studs (8) which carry securing nuts (9). Beneath the nuts are plain washers (7), spring washers (6), and insulating spacers (4,5). The latter are formed in two matching parts with a concavo-convex interface (5a). During installation, the upper spacer (5) is turned to lie parallel to the web of the rail concerned (1). The latter is then lowered on to its sole-piece of resilient material (3) on top of the sleeper, and the spacer is turned through 90 deg to lie on top of the rail foot. The nut is then tightened to compress the washer-spacer assembly (4,5,6,7) and lock the rail into place. Rail location at the corrent gauge is ensured by the lower spacer portion (4). ADVANTAGE - Division of insulating spacer ensures that lower portion sets correct gauge whilst upper part can be swung aside to allow lowering of rail. Dismantling of complete assembly on site is thus avoided, and time is saved.

Description

La présente invention concerne des perfectionnements aux dispositifs déjà connus de fixation d'un rail sur une traverse, à savoir
Utilisation des attaches dites élastiques types STEDEF,
A.P., AP. GV., et SAP reprenant les fonctions de l'attache élastique avec crapaud RN utilise depuis 1950 ou plus récemment des attaches doublement élastiques NABLA type
RNTC ayant fait l'objet du brevet d'invention n" 2.561.681, n 2.580.006, n" 2.450.903, nO 2.566.017, ou tout autre système d'attaches élastiques et isolantes comportant une lame élastique en acier cintrée parallèlement ou perpendiculairement au patin du rail et qui repose sur un intercalaire en polyamide ou d'une matière mécaniquement équivalente.The present invention relates to improvements to already known devices for fixing a rail on a cross member, namely
Use of so-called STEDEF elastic fasteners,
AP, AP. GV., And SAP taking over the functions of the elastic fastener with toad RN has used since 1950 or more recently doubly elastic fasteners NABLA type
RNTC which was the subject of the patent of invention No. 2,561,681, No. 2,580,006, No. 2,450,903, No. 2,566,017, or any other system of elastic and insulating fasteners comprising an elastic blade of bent steel parallel or perpendicular to the shoe of the rail and which rests on a spacer made of polyamide or a mechanically equivalent material.

Un organe de fixation tel que boulon, tirefond ou boulon tirefond vissé ou scellé dans la traverse vient en appui sur l'intercalaire et la lame en acier et se ficher directement ou indirectement dans la traverse béton.A fixing member such as bolt, lag screw or lag bolt screwed or sealed in the cross member comes to bear on the interlayer and the steel blade and is plugged directly or indirectly into the concrete cross member.

Un tel dispositif présente les inconvénients suivants
Excepté le boulon-tirefond qui est scellé ou vissé dans la traverse à l'aide d'un insert, les autres composants de cette attache à savoir
- l'intercalaire en nylon ou autre matière
- la lame élastique en acier
- la rondelle métallique sont distribuées manuellement sur le chantier au droit de chaque traverse.Such a device has the following drawbacks
Except the bolt-bolt which is sealed or screwed into the crosspiece using an insert, the other components of this fastener namely
- the nylon or other material interlayer
- the elastic steel blade
- the metal washer is distributed manually on the site to the right of each crosspiece.

De plus pour protéger le filetage du boulon-tirefond pendant le transport de la traverse, l'écrou de serrage a été amorcé sur la tige du boulon d'où l'obligation de le desserrer et de l'enlever pour introduire sur la tige du boulon l'intercalaire, la lame d'acier et la rondelle après que le rail ait été mis en place- sur la semelle souple posée sur la traverse, après quoi l'écrou peut être vissé.In addition, to protect the thread of the bolt-bolt during the transport of the cross-member, the tightening nut was primed on the rod of the bolt, hence the obligation to loosen and remove it to introduce on the rod of the bolt the interlayer, the steel blade and the washer after the rail has been put in place - on the flexible soleplate placed on the crossmember, after which the nut can be screwed.

Le dispositif faisant l'objet de l'invention a pour but de remédier à ces inconvénients.The object of the invention is to remedy these drawbacks.

L'intercalaire en résine polyamide est coupé en deux éléments (4 et 5). La partie supérieure de l'élément (4) est concave et la partie basse de l'élément (5) est convexe.The polyamide resin interlayer is cut into two elements (4 and 5). The upper part of the element (4) is concave and the lower part of the element (5) is convex.

Le rôle de l'élément dit fixe (4) est d'éviter les déplacements latéraux du rails.The role of the so-called fixed element (4) is to avoid lateral movement of the rails.

L'élément dit mobile (5) supporte la lame élastique (6). The so-called mobile element (5) supports the elastic blade (6).

Grâce à ce dispositif, il est facile d'assembler en usine sur la traverse l'ensemble de l'attache en plaçant parallèlement au patin du rail les éléments (5 et 6) ce qui laisse libre le dessus de la semelle (3) sur lequel viendra reposer le patin du rail.Thanks to this device, it is easy to assemble in the factory on the cross member the whole of the fastener by placing the elements (5 and 6) parallel to the shoe of the rail, which leaves the top of the sole (3) free on which will come to rest the shoe of the rail.

Un léger serrage de l'écrou (9) sur l'organe de fixation (8) suffit à maintenir l'ensemble dans cette position pendant les transports et manutentions de la traverse.A slight tightening of the nut (9) on the fixing member (8) is sufficient to maintain the assembly in this position during transport and handling of the crosspiece.

Une rondelle est interpose entre la lame d'acier (6) et l'écrou de serrage (9). A washer is interposed between the steel blade (6) and the clamping nut (9).
