Description

    OBJECT OF THE INVENTION
  • The present invention relates to a preassembled track apparatus, which can be transported in a preassembled state, intended to be installed on track on a concrete slab. The apparatus can be coupled to the rest of the track and has braced sleepers linked by means of braces which enable the prior consolidation of the track apparatus.
  • More particularly, the invention seeks to provide a preassembled track apparatus, which, after a first verification in the workshop, does not have to be disassembled for transport and assembled at the destination, which is light for transport and reduces assembly times.
    • BACKGROUND OF THE INVENTION
  • Currently, the track apparatuses for ballastless track is supplied as individual components and are assembled at the destination by means of different types of preassembly tools. A prior verification is done at the origin, it is disassembled for transport and reassembled at the destination.
  • In the state of the art, for example, document ES2264478 discloses a method for incorporating track changes in railway rails, as well as changing points in order to carry out this method, which can be partially transported in the preassembled state, with sleepers, with a point blade area, an intermediate rail area and a core area, with a device for the mobile point-changing parts, such as the point blade, servo drives and control installations.
  • However, this and other solutions known in the state of the art incorporate very heavy elements, for which reason the transport thereof is not feasible, since they require many additional levelling parts and very long changeover times are required. Finally, they are designed for tracks without concrete or ballast, so the requirements are different.
    • DESCRIPTION OF THE INVENTION
  • The present invention aims to solve some of the problems mentioned in the state of the art.
  • More particularly, the present invention discloses a preassembled track apparatus which can be transported in a preassembled state comprising at least two rails provided with a skid. The preassembled track apparatus has braced sleepers intended to be fastened on a track on a concrete slab and joining at least two rails, positioned transversely to the direction of the track, comprising an upper sector, limited by two lateral sectors, two seating slabs linked to the upper sector and at least one securing element linked to each seating slab and able to be coupled to the skid such that it retains the rails fastening the track width, a lower sector opposite from the upper sector.
  • The lateral sectors comprise holes separated at a distance in the longitudinal direction of the sleeper and at different heights, and the lower sector comprises cavities close to the holes. The preassembled track apparatus additionally comprises braces parallel to each other which link the braced sleepers, wherein the ends of each brace comprise a joining segment able to be coupled to the holes and the preassembled track apparatus has at least one joining element for each joining segment, which retain the braces in the holes fastening the position thereof.
  • In this manner, the track apparatus can be transported from the origin to the destination in the preassembled state. Thus, it is not disassembled for transport, saving construction time for the railway infrastructure. Additionally, the use of complex tools for levelling at the destination is avoided and electrical insulation is guaranteed.
  • The joining elements can be two or more for each joining segment. One joining element can be positioned inside the cavity and the other joining element close to the lateral sector. In this manner, the braces are better coupled to the special sleepers. The joining segments can be threaded, and the joining elements can be components with a thread complementary to the joining segment, thus ensuring the joining thereof and they are able to be easily coupled and decoupled.
  • The preassembled track apparatus may comprise intermediate sleepers having rods able to be coupled to the track on a concrete slab. These intermediate sleepers can be preassembled as required.
  • Preferably, the braced sleepers may be made of a plastic compound. Preferably, they are made of a light material in order to be able to be transported and which have hardness properties so that they are not damaged and hold up during transport. Furthermore, they must have a good behaviour against humidity and that they do not deteriorate during the transfer and the useful life thereof. Alternatively, the sleepers can be made of a ceramic material. The intermediate sleepers can be made of composite material, wood, concrete or another material suitable for supporting the rails. The braced sleepers can be made of a plastic material and the intermediate sleepers can be made of another of the indicated ones, without the combination affecting the properties of the preassembled track apparatus. The seating slabs can have an elastomer whereon the rail rests, the elastomer can be made of rubber and is placed between the rail and the main slab, in order to mitigate the excessive rigidity of the concrete slab.
