OBJECT OF THE INVENTION
[0001] 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.
[0002] 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
[0003] 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.
[0004] 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.
[0005] 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
[0006] The present invention aims to solve some of the problems mentioned in the state of
the art.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] 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.
[0012] 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.

PREFERRED EMBODIMENT OF THE INVENTION
[0014] Figure 1 shows a perspective view of a preassembled track apparatus (1). The preassembled
track apparatus (1) is intended to be placed on slab and ballastless railway tracks.
The preassembled track apparatus (1) travels assembled from the origin and the shape
and geometry of the preassembled track apparatus (1) remains practically unchanged
until the destination thereof. Once positioned at the destination site, only horizontal
levelling is performed since the position depends on the final point of the assembly.
[0015] The preassembled track apparatus (1) is equipped with rails (2), preferably consolidated
from the origin, braced sleepers (3), braces (11) and joining elements (12). Alternatively,
the rails (2) can be coupled at the destination, as required. At the installation
site of the preassembled track apparatus (1), there is a concrete slab, whereon a
truss is placed, the preassembled track apparatus (1) is levelled and concrete is
poured around the braced sleepers (3).
[0016] Figure 1 shows at least two rails (2) equipped with a skid. Braced sleepers (3) are
shown which are intended to be fastened on a track on a concrete slab and joining
at least two rails (2), positioned transversely to the direction of the track. The
braced sleepers (3) comprise an upper sector (5), limited by two lateral sectors (4),
two seating slabs (7) linked to the upper sector (5), securing elements (8) linked
to the seating slabs (7) and able to be coupled to the skid such that it retains the
rails (2) and fastens the track width. Likewise, it comprises a lower sector (9) opposite
from the upper sector (5).
[0017] Figure 2 shows a detail view of a preassembled track apparatus (1), wherein it can
be seen that the lateral sectors (4) comprise holes (10) separated at a distance in
the longitudinal direction of the braced sleeper (3) and at different heights. The
lower sector (9) comprises cavities (13) close to the holes (10), and braces (11)
are seen parallel to each other which have the possibility of linking the braced sleepers
(3), wherein the ends of each brace (11) comprise a joining segment (6) able to be
coupled to the holes (10) and the preassembled track apparatus (1) has at least one
joining element (12) for each joining segment (6), which retain the braces (11) in
the holes (10) fastening the position thereof.
[0018] In the embodiment shown in figures 2 to 3, intermediate sleepers (14) are seen which
are transverse to the axis of the track, and which also support the rails (2). These
intermediate sleepers (14) are preferably assembled at the destination, independently
from the preassembled track apparatus (1). In another embodiment, these intermediate
sleepers (14) are comprised in the preassembled track apparatus (1) and are preassembled
at the origin. The intermediate sleepers (14) comprise rods (15) in order to be fastened
in the slab. The intermediate sleepers (14) act as support for the rails (2), fastening
and ensuring the position in relation to the height, inclination and separation.
[0019] Figure 3 shows a profile view of a preassembled track apparatus (1). The braced sleepers
(3), transverse to the axis of the track, are seen. Linking each braced sleeper (3),
braces (11) are seen positioned in horizontal planes at different heights. Each braced
sleeper (3) has a cavity (13). In order to secure the position of each brace (11),
the preassembled track apparatus (1) has joining elements (12). Figure 3 shows the
braced sleepers (3).
[0020] The placement of the preassembled track apparatus (1) is performed on a track on
a concrete slab, which is a type of railway track. It has a concrete slab which transmits
the uniformly-distributed stresses to the platform. The preassembled track apparatus
(1) is preassembled in units which fit in a gauge, is carried on a transport vehicle,
