Description
La présente invention a trait à un procédé de fabrication de traverses de chemin de fer en béton armé, ainsi qu'à des éléments employés à la mise en oeuvre de ce procédé, et, en particulier, à un procédé de fabrication de traverses en béton, dans lesquelles est incorporée lors du bétonnage une partie d'un dispositif de serrage combiné pour la fixation de rails, tel que par exemple le dispositif décrit dans le brevet belge 882.165 de la Demanderesse, appelé ci-après serre-rails.The present invention relates to a method for manufacturing railway sleepers in reinforced concrete, as well as to elements employed in the implementation of this process, and, in particular, to a process for manufacturing concrete sleepers. , in which is incorporated during concreting part of a combined clamping device for fixing rails, such as for example the device described in Belgian patent 882,165 of the Applicant, hereinafter called rail clamps.
On sait que la fabrication des traverses de chemin de fer en béton armé s'effectue à l'aide d'un moule, dans lequel sont disposées et dûment immobilisées les susdites parties du dispositif de serrage concerné, après quoi est disposée dans la partie inférieure du moule au moins l'armature supérieure de la traverse en béton à réaliser, armature dont l'immobilisation s'effectue à l'aide d'éléments de support provisoires, qui sont introduits à travers la paroi du moule et qui sont enlevé seulement au stade de vibration du béton, voire à la fin de ce stade, dans le double but, d'une part, de maintenir cette armature au niveau requis et, d'autre part, d'assurer le remplissage des creux formés par ces éléments de support à la fin de la vibration.It is known that the manufacture of railway sleepers in reinforced concrete is carried out using a mold, in which are arranged and duly immobilized the above parts of the clamping device concerned, after which is arranged in the lower part of the mold at least the upper reinforcement of the concrete sleeper to be produced, reinforcement which is immobilized using temporary support elements, which are introduced through the wall of the mold and which are removed only at the concrete vibration stage, or even at the end of this stage, for the double purpose, on the one hand, of maintaining this reinforcement at the required level and, on the other hand, of ensuring the filling of the hollows formed by these elements of support at the end of the vibration.
Inutile de souligner que ce procédé connu est peu pratique et, en outre, peu économique, par suite non seulement des multiples interventions qu'il requiert, mais egalement de l'usure à laquelle sont soumis; ces éléments de support mobiles dans le béton.Needless to say, this known process is impractical and, moreover, uneconomical, as a result not only of the multiple interventions which it requires, but also of the wear to which they are subject; these movable support elements in concrete.
Des essais ont déjà été faits pour éviter ce procédé connu et en supprimer donc les inconvénients susmentionnés en munissant le fond du moule d'éléments d'espacement de conception très simple, faits d'un matériau quelconque approprié et destinés à immobiliser les éléments de l'armature aux écarts mutuels voulus, à l'exemple de la construction routière. Cette solution présente toutefois l'inconvénient que ces éléments d'espacement restent visibles après la finition de la traverse et permettent, dans certains cas, la pénétration de l'humidité jusqu'à l'armature avec toutes les conséquences néfastes qui s'ensuivent, à savoir la corrosion de l'armature et, par conséquent, un affaiblissement inadmissible de la traverse ainsi fabriquée.Tests have already been made to avoid this known process and therefore eliminate the above-mentioned drawbacks by providing the bottom of the mold with spacers of very simple design, made of any suitable material and intended to immobilize the elements of the reinforcement with the desired mutual differences, with the example of road construction. However, this solution has the drawback that these spacing elements remain visible after the crosspiece is finished and allow, in certain cases, the penetration of moisture up to the reinforcement with all the harmful consequences which follow, namely corrosion of the reinforcement and, consequently, an unacceptable weakening of the cross-piece thus manufactured.
Or, la présente invention concerne un procédé et un dispositif pour sa mise en oeuvre qui se prêtent à la suppression des inconvénients des procédés ou dispositifs connus.However, the present invention relates to a method and a device for its implementation which lend themselves to eliminating the drawbacks of known methods or devices.
La solution selon l'invention consiste à cet effet essentiellement en le montage, à travers d'ouvertures prévues dans le fond du moule, de deux parties ou éléments d'un serre-rails qui supportent l'armature supérieure de la traverse; l'immobilisation de ces éléments en dehors du moule; le cas échéant, la disposition d'une armature intermédiaire sur l'armature supérieure; l'introduction d'une tige de liaison par une ouverture de la paroi du moule; et le remplissage du moule de béton, l'armature inférieure étant incorporée au bon moment de manière habituelle et l'ensemble étant finalement compacté par vibration.The solution according to the invention consists for this purpose essentially in mounting, through openings provided in the bottom of the mold, two parts or elements of a rail clamp which support the upper frame of the cross member; immobilization of these elements outside the mold; if necessary, the provision of an intermediate frame on the upper frame; the introduction of a connecting rod through an opening in the wall of the mold; and filling the concrete mold, the lower reinforcement being incorporated at the right time in the usual manner and the assembly being finally compacted by vibration.
Les éléments employés lors de la mise en oeuvre du procédé selon l'invention esquissé dans les lignes précédentes et se présentant essentiellement sous forme desdites parties fixes du serre-rails proprement dit incorporées dans le béton, sont des éléments d'acier ou de fonte, de manière que, dans la première alternative, au moins l'armature supérieure est fixée de manière appropriée, par exemple par soudage, à ces éléments, tandis que, dans la seconde alternative, ces éléments sont munis d'au moins deux appuis pour l'armature supérieure de la traverse.The elements used during the implementation of the method according to the invention sketched in the preceding lines and being essentially in the form of said fixed parts of the rail clamp proper incorporated in the concrete, are elements of steel or cast iron, so that, in the first alternative, at least the upper reinforcement is suitably fixed, for example by welding, to these elements, while, in the second alternative, these elements are provided with at least two supports for the upper reinforcement of the crosspiece.
Les caractéristiques et avantages de la solution selon l'invention ressortiront plus clairement de la description détaillée suivante de quelques exemples d'exécution donnés sans la moindre intention restrictive avec référence aux dessins annexés, où :

La figure 1 représente un moule 1, muni en bas d'ouvertures 2 et 3, dans lesquelles peuvent être disposées de manière adéquate les parties 4, normalement saillantes de la traver- se, des éléments inférieurs 5 d'un serre-rails. Ces éléments 5 sont pourvus d'un collet 6 servant à assurer, de manière aussi simple qu'efficace, leur immobilité dans lesdites ouvertures 2 et 3.FIG. 1 represents a mold 1, provided at the bottom with
Ces éléments sont également fixés en dehors du moule 1 de manière non représentée.These elements are also fixed outside the mold 1 in a manner not shown.
On introduit ensuite dans le moule 1 l'armature supérieure 7 de la traverse à fabriquer et on la dispose sur un appui, respectivement 8 et 9, de chaque élément 5, de manière à réaliser et à maintenir automatiquement l'écartement requis de cette armature par rapport au fond du moule 1.Then introduced into the mold 1 the
Chaque élément 5 présente selon l'invention non seulement les susdits appuis 8 et 9, mais également des appuis intérieurs supplémentaires 10 et 11. Ces appuis, c'est-à-dire soit les appuis 8 et 9 comme dans l'exemple ici représenté, soit les appuis supplémentaires 10 et 11, servent à soutenir une armature respectivement selon la nature de la traverse ou selon celle de l'armature employée, éventuellement indispensable.Each
Sur cette armature 7 est ensuite placée une armature hélicoïdale ou similaire 12, à travers laquelle est insérée une tige de liaison 13 introduite par une ouverture 14 de la paroi concernée du moule 1 et servant à relier deux parties réalisées dans le moule 1 et mutuellement distantes de la valeur voulue.On this
Le moule 1 est maintenant prêt au bétonnage. Le béton y coulé est dûment vibré; après quoi une armature inférieure 15 pourra, le cas échéant, y être noyée.The mold 1 is now ready for concreting. The concrete poured into it is duly vibrated; after which a
On voit de ce qui précède qu'on obtient ainsi non seulement un procédé de fabrication de traverses de chemin de fer en béton armé particulièrement simple et efficace, mais également un moule de bétonnage des plus simples et pratiques, dans lequel l'armature supérieure 7 est dûment immobilisée, sans le moindre risque de déplacement et en des circonstances optimales, à la distance voulue du fond du moule 1 à l'aide d'éléments solidaires du serre-rails et munis d'appuis appropriés servant à supporter l'armature.It can be seen from the foregoing that this not only provides a method of manufacturing railway sleepers in particularly simple and effective reinforced concrete, but also a very simple and practical concreting mold, in which the
Les figures 5 et 6 représentent un mode d'exécution préféré des éléments 5. On voit que les appuis 8, 9, 10 et 11 se présentent sous forme d'encoches respectivement 16, 17, 18 et 19, dans lesquelles prennent les parties correspondantes de l'armature, qui est ainsi non seulement dûment supportée,; maison même temps bien immobilisée et bloquée contre tout risque de déplacement quelques soient les circonstances.Figures 5 and 6 show a preferred embodiment of the
Enfin, les figures 7 et 8 représentent à titre d'exemple une traverse de chemin de fer fabriquée par le procédé et à l'aide d'éléments selon l'invention, c'est-à-dire en particulier à l'aide des éléments représentés par les figures 5 et 6.Finally, FIGS. 7 and 8 show by way of example a railway sleeper manufactured by the method and using elements according to the invention, that is to say in particular using the elements shown in Figures 5 and 6.
En ce qui concerne les modes d'exécution décrits dans les lignes précédentes, lesdits éléments 5 sont généralement des pièces de fonte. Par contre, si ces éléments 5 sont des pièces d'acier, les appuis 8, 9, 10 et 11 ou 16, 17, 18 et 19, peuvent être supprimés, étant donné que l'armature 7 est fixée aux éléments 5, par exemple par soudure par points. avant l'introduction de ces éléments dans le moule.With regard to the embodiments described in the preceding lines, said
En effet, la fixation de l'armature par soudure par points aux éléments 5 en dehors du moule 1 s'effectue simplement en plaçant ces éléments dans un support provisoire à côté d'appuis portant l'armature à la hauteur requise par rapport aux éléments pendant le soudage par points. Les éléments 5 ainsi réunis par l'armature 7, sont ensuite introduits tels quels dans le moule 1, de sorte que le processus de fabrication poursuivre dela manière décriteIndeed, the fixing of the armature by spot welding to the
Il va sans dire que l'invention ne se limite pas aux exemples de mise en oeuvre décrits dans les lignes précédentes, mais en prévoit toutes sortes de variations, d'additions et d'adaptations en ce qui concerne la forme et les dimensions de la traverse concernée fabriquée à l'aide desdits éléments, évidemment à condition que soit respecté son principe général et que ne soient pas dépassées ses limites, définies par les revendications formulées ci-après.It goes without saying that the invention is not limited to the examples of implementation described in the preceding lines, but provides for all kinds of variations, additions and adaptations thereof with regard to the shape and dimensions of the cross member concerned manufactured using said elements, obviously provided that its general principle is respected and that its limits are not exceeded, defined by the claims formulated below.
