DESCRIPCIÓNDESCRIPTION
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
Es objeto de la presente invención un sistema de vias de ferrocarril en placa hormigonada asi como el sistema de instalación del mismo, que gracias a los elementos que constituyen el sistema de vias permiten en cualquier momento de la obra la nivelación en altura de los railes asi como la alineación de los mismos en cualquier momento, asegurando el paralelismo entre carriles.The object of the present invention is a railroad system in concrete plating as well as its installation system, which thanks to the elements that constitute the rail system allow at any time of the work the leveling of the rails so as their alignment at any time, ensuring the parallelism between lanes.
En los sistemas de vias de ferrocarril en placa hormigonada todo queda cubierto por hormigón, salvo las cabezas de los propios railes.In the railroad systems in concrete plate everything is covered by concrete, except for the heads of the rails themselves.
Caracteriza a la presente invención los elementos empleados en el sistema de vias, cuyas características constructivas y técnicas son tales que permiten una nivelación en altura, una alineación de cada uno de los railes, y el paralelismo entre si de los railes.It characterizes the present invention the elements used in the track system, whose constructive and technical characteristics are such that they allow a leveling in height, an alignment of each of the rails, and the parallel between them of the rails.
Por lo tanto, la presente invención se circunscribe dentro del ámbito de los sistemas de vias que quedan cubiertos por hormigón excepto las cabezas de los propios railes .Therefore, the present invention is circumscribed within the scope of road systems that are covered by concrete except the heads of the rails themselves.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Las vias en placa hormigonada son conocidas, se utilizan principalmente para accesos ferroviarios a talleres, puertos, hangares, cocheras etcétera, donde normalmente discurren trenes con cargas elevadas y a velocidades lentas.Concrete track tracks are known, they are mainly used for rail access to workshops, ports, hangars, garages and so on, where trains with high loads and slow speeds normally run.
Tradicionalmente, en los sistemas de vias en placa hormigonada, se dispone un lecho de hormigón o balastro y sobre éste la traviesa de madera u hormigón, a la que se fija y atornilla el rail. Este sistema plantea varios inconvenientes : - El empleo de traviesas, su ajuste y disposición no es económicamente hablando la solución más rentable.Traditionally, in concrete track systems, a concrete or ballast bed is arranged and on it the wooden or concrete crossbar, to which the rail is fixed and screwed. This system poses several drawbacks: - The use of sleepers, their adjustment and arrangement is not economically speaking the most cost effective solution.
Por otro lado, este sistema no permite una nivelación en altura durante la obra, con la consiguiente reducción del gálibo tradicional, lo cual en algunos casos es un claro inconveniente. Tampoco permite la alineación entre los railes ni modificación del ancho de via en cualquier momento durante la obra, asi como las posteriores revisiones técnicas sin necesidad de levantar la via .On the other hand, this system does not allow a leveling in height during the work, with the consequent reduction of the traditional gauge, which in some cases is a clear inconvenience. Nor does it allow alignment between the rails or modification of the track width at any time during the work, as well as subsequent technical revisions without the need to lift the track.
No permite la incorporación de carriles adicionales para anchos de vias diferentes.It does not allow the incorporation of additional lanes for widths of different tracks.
Por lo tanto, es objeto de la presente invención de sistema de vias de ferrocarril en placa hormigonada, conseguir un sistema que supere los anteriores inconvenientes, permitiendo una nivelación en altura, una alineación de cada uno de los railes y el paralelismo de los mismos en cualquier momento durante la obra, gracias al empleo de una pieza regulable de fijación, permitiendo la instalación de un tercer carril y quedando libre de mantenimiento . DESCRIPCIÓN DE LA INVENCIÓNTherefore, it is the object of the present invention of a railroad system in a concrete plate, to achieve a system that overcomes the previous drawbacks, allowing a leveling in height, an alignment of each of the rails and the parallelism thereof in any time during the work, thanks to the use of an adjustable fixing piece, allowing the installation of a third lane and being maintenance free. DESCRIPTION OF THE INVENTION
El sistema de vías de ferrocarril en placa hormigonada objeto de la invención consiste en disponer en primer lugar un lecho o base de sustentación de apoyo a los mismos, sobre este lecho o base se dispone una estructura de soporte de los raíles, que substituyen a las tradicionales traviesas .The system of railroad tracks in a concrete plate object of the invention consists in firstly arranging a support bed or support base thereon, on this bed or base a support structure of the rails is arranged, which replace the Traditional naughty
La estructura de soporte de los raíles consiste en una placa o chapa de acero rectangular que se dispone bajo los raíles, sirviendo de apoyo a los mimos, quedando el conjunto formado por la chapa y los raíles soportado por unos pernos regulables dispuestos a ambos lados del raíl, y no preferentemente de forma enfrentada.The support structure of the rails consists of a rectangular steel plate or sheet that is arranged under the rails, serving as a support for the pampering, leaving the assembly formed by the sheet and the rails supported by adjustable bolts arranged on both sides of the rail, and not preferably facing each other.
Por otro lado, se emplean unas piezas regulables de fijación de los raíles que se disponen sobre las placas de acero. Estas piezas de regulación permiten la alineación de los raíles, y aseguran el paralelismo entre ellos, además de absorber los esfuerzos laterales del sistema.On the other hand, adjustable parts for fixing the rails that are arranged on the steel plates are used. These regulating pieces allow the alignment of the rails, and ensure the parallelism between them, in addition to absorbing the lateral forces of the system.
El proceso de montajes del sistema de vías objeto de la invención, comprende los siguientes pasos: - Tendido de una base o lecho donde se sustentará todo el sistema de vías.The assembly process of the track system object of the invention comprises the following steps: - Laying of a base or bed where the entire track system will be supported.
Sobre dicho lecho inferior se disponen unos pernos roscados que sirven de soporte de las planchas de acero que están dispuestas de raíl a raíl y sirven de apoyo a los mismos. La nivelación se consigue con la tuerca que hay debajo de la chapa.On said lower bed there are threaded bolts that support the steel plates that are arranged from rail to rail and serve as support for them. The leveling is achieved with the nut under the plate.
Fijación de los raíles sobre las chapas, empleando unos clips regulables de fijación que bloquean lateralmente el carril y absorben los esfuerzos laterales, de modo que se garantiza el paralelismo de los railes en el tiempo. Sujeción o fijación del perno al sistema hasta la mitad de la altura del perno, lo que permite ajustes en altura.Fixing the rails on the plates, using adjustable fixing clips that laterally block the rail and absorb the lateral forces, so that the parallelism of the rails in time is guaranteed. Fastening or fixing the bolt to the system up to half the height of the bolt, which allows height adjustments.
Finalización de la instalación con la alineación y verificación del paralelismo entre railes .Completion of the installation with the alignment and verification of the parallelism between rails.
Este sistema de vias de ferrocarril permite como anteriormente ya se ha comentado, una nivelación en altura de los railes durante la obra, mediante la tuerca que hay debajo de la chapa, una regulación de la alineación de cada uno de los railes y el paralelismo de los railes en cualquier momento de la obra antes del embebido final de hormigón, gracias al empleo de los clips regulables de fijación de los railes a las planchas de acero.This railroad system allows, as previously mentioned, a leveling of the rails' height during the work, by means of the nut under the sheet, a regulation of the alignment of each of the rails and the parallelism of the rails at any moment of the work before the final embedding of concrete, thanks to the use of the adjustable clips for fixing the rails to the steel plates.
Los clips regulables de fijación se componen de elementos que, una vez dado el par de apriete recomendado, aseguran el bloqueo del sistema, la regulación lateral de las piezas de fijación, permitiendo garantizar el ancho de via que sea necesario.The adjustable fixing clips are made up of elements that, once given the recommended tightening torque, ensure the locking of the system, the lateral adjustment of the fixing parts, allowing to guarantee the necessary track width.
Por otro lado, además del consiguiente ahorro al sustituir las tradicionales traviesas por un conjunto de planchas de acero y pernos, permite la disposición de carriles adicionales para el caso de que sea necesario una adaptación de anchos de via.On the other hand, in addition to the consequent savings when replacing the traditional sleepers with a set of steel plates and bolts, it allows the provision of additional rails in case an adaptation of track widths is necessary.
Con este sistema de vias, éstas quedarán exentas de todo mantenimiento, ya que la manipulación y ajustes solamente podrán realizarse durante la obra, puesto que una vez instalado no podrá realizarse reparación ni mantenimiento alguno, debido a que habría que levantar la via al quedar cubiertas de hormigón excepto las cabezas de las mismas.With this system of roads, these will be exempt from all maintenance, since the manipulation and adjustments can only be carried out during the work, since once installed it cannot be repaired or any maintenance, because it would be necessary to lift the road to be covered with concrete except their heads.
