    [0001]
    [0002] Concrete plinth for railway tracks, railway track that incorporates said sockets and method of installation of the track
    [0003]
    [0004] Object of the invention
    [0005]
    [0006] The invention relates to a prefabricated concrete plinth (also called a plinth), for the "in-situ" execution of a support or screed for the fixing of rails of terrestrial railways.
    [0007]
    [0008] An object of the invention is to provide a prefabricated plinth that improves the quality of the installation of the railway, reduces the time of execution of work, and also allows reducing the space and costs derived from the transport of the plinth and associated fixings the same.
    [0009]
    [0010] The invention also relates to a railway track, and to a method for the installation of said railway track.
    [0011]
    [0012] BACKGROUND OF THE INVENTION
    [0013]
    [0014] Different types of railways are known that, instead of using ballast as a base for the rails, they use prefabricated concrete elements that are transported and installed in situ by concreting.
    [0015]
    [0016] These systems of roads based on prefabricated elements are expensive and complex to execute, since they are affected by different factors such as the accessibility of the site of the work, the transport and handling of prefabricated concrete elements of large size and weight, as well as as the laborious process of installation that requires multiple operational phases, such as pouring concrete in several phases during installation.
    [0017] Therefore, it is necessary in this technical sector to reduce the execution times of the work and at the same time improve the quality of it.
    [0018]
    [0019] Description of the invention
    [0020]
    [0021] The invention solves the above-mentioned deficiencies of the state of the art, by means of a base comprising an elongated concrete body, having a platform defining a base and a base, and also having a lateral curb arranged in the base upper, which extends along the body, so that the body comprises a form "L" generically in a cross-sectional view thereof.
    [0022]
    [0023] This curb serves to prevent derailments of the vehicle traveling on the rails, such as a train, in the event of an accident.
    [0024]
    [0025] Said body has a cavity in the interior of the platform that extends along the same, and that opens into the lower base, as well as openings in the upper base of the platform that are communicated with said cavity.
    [0026]
    [0027] In this way, the upper base is communicated with the lower base through said openings and said cavity, so to install the base, it is sufficient to pour concrete only once through the upper openings, so that it extends through the entire cavity filling it so that the base is properly fixed to the hearth.
    [0028]
    [0029] Preferably, said openings extend in part on the internal side face of the curb, which allows the openings to be large, and therefore facilitates the coupling and positioning of a rail fastener.
    [0030]
    [0031] The platform is a generally rectangular prismatic body, which has at the lower base of two support feet on the ground arranged in correspondence with the larger lateral faces of the platform. Preferably, the base incorporates respective bands of elastic material attached to the lower face of said support feet, which they serve to prevent concrete leaks through the lower sections of the base during the concreting phase.
    [0032]
    [0033] Some of the most significant advantages of the invention are the following:
    [0034]
    [0035] - the quality of the works is increased and improved,
    [0036]
    [0037] - the execution time is reduced, due to the cavities of the plinth that allow to pour the concrete in a single phase,
    [0038]
    [0039] - space and transport costs are reduced,
    [0040]
    [0041] - allows to use different types of fasteners for rails according to the requirements of the track quickly and efficiently, having these wide freedom of movement during installation in the direction of any of the three axes (x, y, z), as well as its rotation around each of these axes, adapting them according to the irregular topography of the terrain,
    [0042]
    [0043] - prevents leaks from the concrete through the lower sections of the plinth during the concreting phase.
    [0044]

    [0060] PREFERRED EMBODIMENT OF THE INVENTION
    [0061]
    [0062] Figure 1 represents an example of embodiment of the base of the invention, where it can be seen that it comprises an elongated body (1) obtained as a single piece of concrete. The body (1) has a platform (3) which is a generally prismatic rectangular body with two larger lateral faces and two smaller lateral faces, and which defines an upper base (3a) and a lower base (3b).
    [0063]
    [0064] The body (1) furthermore has a lateral curb (2) emerging from the upper base (3a), so that the body (1) has a generally "L" shape in a cross-sectional view thereof, as shown in FIG. shown in drawing 1A.
    [0065]
    [0066] The curb (2) extends along the body (1), and has a rectangular shape generally in a transverse view thereof, with an internal side face and an outer side face.
    [0067] The body (1) has a cavity (4) in the interior of the platform that extends along the same, and that opens into the lower base (3b). The body (1) also has openings (5) in the upper base (3a) of the platform that are connected to said cavity (4), which are arranged transverse to the longitudinal direction of the body (1).
    [0068]
    [0069] Preferably, the openings (5) extend part of said internal side face of the curb, as can be seen in particular in the drawings 1D and 1E, which facilitates the insertion and movement of the rail fixings during installation.
    [0070]
    [0071] It can be seen in figure 1, that the upper base (3a) is communicated with the lower base (3b) through said openings (5) and cavity (4).
    [0072]
    [0073] The body (1) has in the lower base, of two feet (6) that serve as support on the ground, which are arranged in correspondence with the larger lateral faces of the platform (3), and which extend along of the longitudinal body (1).
    [0074]
    [0075] Two bands (7) of elastic material are joined to the lower face of said support feet (6), which serve to raise the base on the ground and which, thanks to its elasticity, adapt to the unevenness of the ground. In this way it is possible to avoid leaks of concrete through the lower sections of the plinth during the concreting phase. The bands (7) can be made with a plastic material, such as recycled rubber, expanded polystyrene, etc.
    [0076]
    [0077] Preferably, the base has at least one pair of metal bars (13), in correspondence with each of the openings (5), as shown in drawing 1F, and serve as reinforcement reinforcement once the concrete has been concreted. interior of the socket.
    [0078]
    [0079] As shown in the drawings 1B, C, F, the body (1) integrates respective first support beams (8) arranged in an off-center manner in the lower part of the openings (5). Respective second support beams (9) are also arranged in an off-center manner opposite the first beams (8). These second beams (9) emerge from an internal face of the platform (3).
    [0080] Now, an alternative of said first and second beams (8, 9) can be materialized in respective steel bars.
    [0081]
    [0082] As illustrated in Figure 2, the base of the invention allows various types of fixings (10, 11, 12) to be used indistinctly for rails according to the requirements of the track. For example, the following types of fixings can be used:
    [0083]
    [0084] Fixation (10) .- composed of: concrete block (20) comprising a plate (21) rail seat (17), clips (22) fastening the rail, bolts (23) anchor clips, lag screws (24) to concrete.
    [0085]
    [0086] Fixation (11) .- composed of: concrete block (20) shoes in a rubber box (25) as a cover so that the block can bounce on an inner elastic surface, in which the block comprises rail seat plate (26), clips (27) for fastening the rail, fixings of the clips to rail.
    [0087]
    [0088] Fixation (12) .- composed of: concrete block (20) comprising a rail seat plate (28), clips (29) fastening the rail, bolts (30) anchoring the clips, clamping clamp (31) ), lower reinforcing bars (32) to the concrete.
    [0089]
    [0090] In this way any type of fixation (10-12) can be supplied from the factory together with the base (see Figure 3), housing a fixation in each opening (5) so that it is supported on the first and second beams (8, 9), thus taking advantage of the interior of the base to house the fixings during transport, in order to occupy little space.
    [0091]
    [0092] The assembly can be transported from the factory as a unit with the base itself, to the same place of the installation, thus substantially reducing costs of material transport and installation time.
    [0093]
    [0094] In situations that require it, a block of concrete (15) can be incorporated as a hearth, integrating partially embedded, a succession of reinforcement bars (14). Said block (15) is suitable for use when it comes to carrying out the installation of the base on soft ground, thus providing the installation with greater rigidity and avoiding vertical displacements, so that the bars (14) collaborate in the reinforcement of the concrete in the subsequent concreting phase.
    [0095]
    [0096] Therefore, a railroad according to the invention (Figure 6), would comprise a plurality of sockets (1,1 ') such as those described above, installed on the ground or on a concrete slab (15), with fixings (10-). 12) of rails (17) housed in the openings (5) of the plinth, and the entire set is then concreted, by pouring concrete (16) that extends through the cavity (4) of the sockets leaving the bars embedded ( 13) or even bars (14), and finally the openings (5) are filled around the fixings (10-12), the fixings being partially immersed in the concrete, as can be seen in particular in figure 5.
    [0097]
    [0098] The method of installing the railway track can be seen from the figures 3 to 6, and is described below:
    [0099]
    [0100] - Sockets (1) are deposited on the ground itself or otherwise on the concrete block (15), so that the baseboards already have the fixings (10-12) housed inside the openings (5), the fixings supported on the first and second beams (8,9);
    [0101]
    [0102] - the rails are placed and fixed to the fixings (10-12);
    [0103]
    [0104] - leveling tools (18) of the rails are placed. Such tools are adjusted in height, so that when the rails are fixed to the fixings and that these are smaller than the openings (5), there is no interaction between the fixings and openings (5), defining gaps (19) around of the fixings, in order that the fixings have ample freedom of movement during installation in the direction of any of the three axes (x, y, z), as well as their rotation around each of said axes, adapting them according to of the irregular topography of the land, as represented by the arrows in figure 4;
    [0105]
    [0106] - additionally, the recess (19) allows the pouring of concrete (16) that will fill the cavities (4) inferiorly up to the concrete block (15) or, alternatively, the slab, thus as the space around the fixings (10-12) sealing the whole. On the other hand, the bands (7) prevent that during said phase, the concrete seeps under the support feet (6) and the irregular terrain.
