    [0001] GUIDED TRANSPORT ROAD SECTION FOR BALLAST-FREE AND BALLAST-FREE ROADS FORMED OF A PLURALITY OF SUCH SECTIONS 1. TECHNICAL FIELD OF THE INVENTION The invention relates to non-ballast tracks for guided transport vehicles, such as railway vehicles. or pneumatic. The invention relates more particularly to guided transport path sections making it possible to form, by a successive arrangement of a plurality of sections, a track without ballast. 2. Technological background Since the birth of railroad tracks, it is known to install these tracks on ballast, that is to say on a bed of crushed stone or gravel. The ballast makes it possible to distribute on the platform of the underlying track the forces transmitted by the sleepers under the action of the rolling loads. The ballast thus makes it possible to limit the settlement of the platform. The ballast finally allows to embed sleepers to limit their movements and deformations. For several years, the projects of track without ballast multiply, in particular the tracks on slabs of concrete. Indeed, these track systems have the advantages of minimizing track maintenance costs and extending their service life. These non-ballast tracks generally comprise a concrete or asphalt foundation layer on which a cast-in-place or prefabricated concrete slab is used to support and anchor the rails of the track. One of the difficulties encountered when producing such a track without ballast is the precision required when laying the concrete slabs on the underlying subgrade because it directly determines the geometry of the track. In addition, in the event of a necessary overhang on the route of the track, it is necessary to adapt the earthwork of the foundation layer to form the cant prior to the placement of the concrete slabs. Adjusting the center distance can also cause technical problems. Finally, after adjusting the geometry of the track, it is necessary to seal or anchor the concrete slabs so that they are permanently immobilized. The inventors have therefore sought to propose a new concept of non-ballast track which solves at least some of the disadvantages of known non-ballast tracks. OBJECTIVES OF THE INVENTION The invention aims to overcome at least some of the disadvantages of known non-ballast channels. In particular, the invention aims to provide, in at least one embodiment, a section of track which does not require a slab of concrete or poured asphalt to be able to be installed. The invention also aims to provide, in at least one embodiment, a track section whose geometry (cant, height) can be adjusted after installation. The invention also aims to provide, in at least one embodiment, a section of track which allows a correction of the geometry of the track thus formed after its installation and at any time during the life of the track as well. formed. The invention also aims to provide, in at least one embodiment, a section of track that can be quickly installed by the track laying teams. The invention also aims to provide, in at least one embodiment, a track section which has easy maintenance. The invention also aims to provide, in at least one embodiment, a section of track that is insensitive to flooding.
    [0002] The invention also aims to provide, in at least one embodiment, a section of track that can be installed on various types of engineering structures, such as tunnels, viaducts, including viaducts U, bridges, booms, etc. The invention also aims to provide, in at least one embodiment, a section of track that can be adapted to different types of guided vehicles, including rail vehicles or vehicles, passenger traffic vehicles 3036711 3 high speed, freight , metro, tram, and equivalent vehicles. 4. DISCLOSURE OF THE INVENTION To this end, the invention relates to a section of guided transport path intended to be fixed on a track platform without ballast, characterized in that said section comprises: a track panel comprising two sills extending along a longitudinal direction and at least two cross members integral with said longitudinal members and extending transversely between them, each sill further comprising an upper longitudinal groove 10 for receiving a rolling element and / or guiding a guided transport vehicle, such as a rail, a plurality of supports adapted to be fixed to said track platform and configured to support said panel above said platform of said track, each support comprising a fixing stud at the platform, a cradle for supporting a sill mounted vertically movable in said pad, and means for vertically moving said cradle relative to the pad it plot so as to adjust the height of this sill relative to said platform, and define the devers of the section of channel thus formed by a coordinated setting of the different cradles. A section of lane according to the invention thus makes it possible to adjust the precise geometry of the lane after the installation of the lane on the platform of the lane. In particular, the height of each sill (and therefore the height of each guide and / or bearing element housed in the groove of the sill, hereinafter referred to as "rail" for simplicity) can be adjusted, after installation. This height of the sill (that is to say the distance between the platform and the sill) is defined and adjusted by a displacement of the support cradle of a sill. This displacement of the cradle is obtained by the implementation of the means of vertical displacement of the cradle.
    [0003] Throughout the text, the term "platform" of the track defines a landscaped ground on which the track section according to the invention is intended to be fixed.
    [0004] 3036711 4 The track platform corresponds to the terracing of the track on which the studs of the track section are directly fixed. According to the invention, this platform is devoid of any ballast. In addition, each sill being supported by at least one support - preferably two sill supports - a coordinated setting of the cradles of the different supports allows to form a cant. To do this, the supports of a sill are adjusted to a different height of the supports of the other sill, which allows to rotate the track panel around a longitudinal direction axis, thus forming the back. According to an advantageous variant, the track section 10 is configured to allow the pivoting of the panel about a longitudinal direction axis whose position is coincident with the tread of the rail supported by the sill whose height has remained fixed, forming thus the cant. According to the invention, a section of track does not require forming a cant directly on the earthwork of the track prior to the installation of the track. This devers can be formed after installation, by an inclination of the track panel, which facilitates the laying operations of the track. In addition, a track section according to the invention allows compensation differential settlements of the platform of the track by an individual adjustment of each stud. The lane section adjustment feature of the invention also allows adjustment and correction of the lane geometry during its lifetime. The accuracy of the earthworks is also less critical than with prior art tracks by the possibility of being able to refine the height of each sill with respect to the platform and to make up for any earthworks defects.
    [0005] A track section according to the invention is directly attached to the platform of the track and does not require the pouring of a concrete or asphalt slab. Also, the realization of a transport path implementing track sections according to the invention is carried out more quickly than with the prior art ballastless track techniques.
    [0006] In addition, the track extends above the platform, allowing the water to pass under the track panel in case of flooding of the platform.
    [0007] Each lug of a lane panel of a section according to the invention comprises an upper longitudinal groove for receiving a rolling element and / or guiding a guided transport vehicle, such as a rail and its associated fastening system. The section can therefore be used with different types of vehicle, the type of which is defined during the installation of the rolling element and / or guide. In all the following and for the sake of simplicity, the term "rail" is used generically to define the rolling elements and guide elements that can be housed in the grooves of each sill, it being understood that it is a rail as such for a railway vehicle, but a running track for a pneumatic vehicle. A section according to the invention comprises a cradle mounted vertically movable in the stud and vertical displacement means of this cradle relative to the stud.
    [0008] Advantageously and according to the invention, these means of vertical displacement of the cradle relative to the pad comprise: a wedge wedge mounted horizontally movable relative to said pad, said wedge having a wedge inclined upper plane conjugated to a lower inclined plane of said cradle said wedge bearing said cradle, means for horizontally locking said cradle relative to said pad, so that a horizontal displacement of said wedge wedge spontaneously causes a vertical displacement of said cradle, means for horizontal displacement of said cradle; wedge in said stud. According to this advantageous variant, the vertical displacement of the cradle relative to the stud of a support is achieved by a horizontal displacement of a wedge wedge relative to the stud, said wedge carrying said cradle, conjugated to a horizontal blocking of the cradle. In particular, the wedge wedge and the cradle have conjugate inclined planes, i.e. inclined planes in continuous contact with each other. In addition, the cradle being blocked horizontally against the pad, a horizontal displacement of the wedge wedge causes the sliding of the inclined planes one on the other, which results in a vertical displacement of the cradle, its horizontal displacement being constrained by the locking means. Advantageously and according to the invention, the horizontal blocking means 5 of said cradle relative to the stud comprise a threaded insert engaged in said stud and extending horizontally through the stud bearing against said cradle. According to this variant, the horizontal blocking of the cradle is achieved by an adjusting screw connected in a threaded insert engaged in the stud and which bears against the cradle to prevent any horizontal movement.
    [0009] Advantageously, each support comprises means for horizontal displacement of said wedge wedge in said stud. According to an advantageous variant, these horizontal displacement means of said wedge wedge comprise a set screw bearing against said wedge wedge and engaged in said stud extending horizontally through said stud.
    [0010] Advantageously and according to this variant, said wedge has a lower inclined plane conjugated to an upper inclined plane of said stud on which is mounted said wedge wedge, so that in the absence of a bearing force of said adjustment screw on said wedge wedge, said wedge wedge slides spontaneously by gravity on said inclined plane of said stud.
    [0011] Thus, according to this variant, the adjustment screw abuts against the wedge wedge to push it and thus ensure a vertical upward movement of the support cradle. In case of retraction of the adjusting screw, the corner wedge spontaneously comes by gravity slide on the inclined plane of the stud, which causes a vertical downward movement of the support cradle.
    [0012] According to another variant, one end of the adjusting screw is integral with the wedge wedge so that a displacement of the screw relative to the stud causes, in the direction of rotation printed on the screw, an upward movement. or down the support cradle carried by the wedge wedge. Advantageously and according to the invention, each sill further comprises two stops arranged transversely on a lower face of the sill and configured to be able to receive between them a cradle so that it can, one 7 times housed between the two stops, lock longitudinally each sill. The stops arranged transversely under each sill prevent longitudinal slippage of the sill relative to said cradle. Advantageously and according to the invention, each sill has a rounded lower face 5 shaped to the upper faces of said cradles of said supports. This rounded face is advantageously cylindrical, in the mathematical sense of the term, that is to say that it has a surface defined by the displacement of a line parallel to itself on a generator, which in this case is a Semi circle.
    [0013] According to this variant, the cradle and the sill have complementary shapes such that the cradle encloses the sill and forms with it a continuous contact area of support. The rounded shape also prevents transverse movement of the sill when mounted and supported by the cradles. Indeed, the side walls of the cradle then form transverse stops. Advantageously, a section according to the invention comprises two sill supports. Advantageously and according to the invention, said longitudinal members and said supports are formed of concrete and said sleepers are steel tubes.
    [0014] Advantageously and according to the invention, for at least one support, the attachment stud to the platform is mounted on a metal block comprising a metal plate and a plurality of steel tubes welded under the metal plate, said metal block being intended to be inserted into said track platform by threshing or sinking to fix this support.
    [0015] Such a metal block comprises for example sixteen steel tubes welded to the metal plate secured to the lower part of the fixing stud. The fastening of the fastening stud to the metal solid can be of any type. For example, the mounting pad is glued to the metal plate, or bolted to the metal plate.
    [0016] According to another variant, the stud is fixed to the platform by micropiles, for example by three micro-piles. These micro-piles can be darkened, beaten or drilled in the track platform. The invention also relates to a track without ballast for a guided transport vehicle comprising a track platform and a plurality of track sections according to the invention fixed successively on said track platform.
    [0017] The invention also relates to a track section and a track formed of a plurality of track sections according to the invention characterized in combination by all or some of the features mentioned above or below. 5.

DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION In the figure, the scales and the proportions are not strictly adhered to for purposes of illustration and clarity. Throughout the following detailed description with reference to the figures, unless otherwise indicated, each element of a track section is described as it is arranged when the track section is mounted and secured to a horizontal track platform. This arrangement is in particular represented in FIG. 1. In addition, identical, similar or similar elements are designated by the same references. Finally, the terms longitudinal, transverse and vertical 30 are used in a nonlimiting manner with reference to the trihedron L, T, V as shown in the figures. The longitudinal direction corresponds to the main direction of the track section. The longitudinal direction designates in particular the direction in which a guided transport vehicle moves on the track formed by a plurality of track sections according to the invention. As shown in FIG. 1, a track without ballast according to the invention intended to allow the transport of a guided vehicle, such as a railway or pneumatic vehicle, comprises a track platform 15 without ballast and a plurality of sections. , 17 track according to the invention fixed successively on the platform 15. Figure 1 shows only two sections 16, 17 successive. Nevertheless, it goes without saying that, in practice, a track or a track section comprises a multitude of track sections successively arranged on an earthworks (or a platform 15). In the following, a section of track will be described in detail with reference to section 16 of track, understood that other sections of track may be identical.
    [0018] As shown in Figure 2, the track section 16 comprises a track panel 20 and four supports 31, 32, 33, 34 fixed on the platform 15. The support 34 is shown in exploded perspective to show the different support members which are described with reference to Figures 7 and 8 below. As shown in FIGS. 5 and 6, a track panel 20 comprises two longitudinal members 21, 22 which extend along the longitudinal direction, which coincides with the direction of traffic of the vehicles, once the track has been installed. The track panel 20 also comprises two crosspieces 23, 24 which extend transversely to the longitudinal members 21, 22. According to the embodiment of the figures, these crosspieces 23, 24 are formed by metal tubes whose ends 25 are secured to the longitudinal members. 21, 22. These stringers are preferably formed of concrete. A track panel 20 according to this embodiment has a general ladder shape. According to other embodiments not described, a track panel 20 may comprise concrete sleepers and form other shapes than a ladder. For example, the cross members may be provided at each longitudinal end of the longitudinal members. The sill 21 will now be described in detail, it being understood that the sill 22 has an identical architecture. The sill 21 comprises an upper longitudinal groove 25 for receiving a rolling element and / or guiding a guided transport vehicle, such as a rail. This groove 25 therefore extends longitudinally and is configured to receive the guide or rolling element on which the transport vehicle will be able to circulate. In the case of a railway vehicle, the guide element is a rail 41. This groove is also intended to receive the rail fastening means to the sill. The sill 21 also comprises, according to a preferred embodiment, a rib forming a wall 26 extending longitudinally at the lateral edge of the sill 21. This wall 26 makes it possible to block a vehicle laterally in the event of a derailment. This wall 26 is therefore a safety member of the track. This wall 26 also acts as a noise canceling device by blocking the propagation of sound waves emitted due to the interactions of the vehicle and the rail. Each sill also comprises two stops 27, 28 transverse formed on the lower surface of the sill. These stops are spaced longitudinally from each other by a distance substantially equal to the longitudinal dimension of a cradle of a support (hereinafter described with reference to FIGS. 7 and 8) so that once the cradle is housed between the two stops, it ensures a longitudinal locking of the sill 21 and therefore a blocking of the corresponding track panel 20. Each support 31, 32, 33, 34 is adapted to be fixed to the track platform and configured to be able to support part of a sill.
    [0019] We will now describe support 34 in detail, it being understood that the other supports have an identical architecture. The support 34 comprises a stud 35 for fixing to the platform 15. This stud 35 comprises fixing according to the embodiment of Figure 7 a generally cylindrical shape. In particular, the stud 35 comprises a base 35a 30 intended to rest on the platform 15, side walls 35b, a rear wall 35c, and a bottom 35d. The side walls 35b, the rear wall 35c and the bottom 35a, 3036711 12 form a housing for receiving the other members of the support 35. These members comprise a wedge wedge 36 which rests on the bottom 35d of the stud 35, and a support cradle 37 of the sill 22 which rests on the wedge wedge 36. In addition, the support comprises a screw 38 for adjusting and a screw 39 for locking the horizontal cradle 37, each screw extending through the wall rear 35c of the stud by a threaded hole formed in the rear wall 35c. Each threaded hole has a thread conjugated to the thread of the screw that it receives so that the screw is engaged in the rear wall and a rotation of this screw in this tapped hole causes a horizontal displacement of the screw by compared to the pad 35.
    [0020] The wedge wedge 36 further has an inclined top plane conjugated to an inclined lower plane of the cradle 37. The wedge wedge 36 also has, according to the embodiment of FIGS. 7 and 8, an inclined lower plane conjugated to a plane tilted upper end 35d of the stud 35. Thus, a rotation of the adjusting screw 38 by an operator results in a displacement of the wedge wedge on the bottom 35d of the stud 35. This displacement of the wedge wedge 36 causes a slip on the other of the inclined planes of the wedge wedge 36 and the cradle 37. The cradle 37 being blocked horizontally by the locking screw 39, the cradle 37 is spontaneously driven in vertical displacement in the stud 35.
    [0021] In other words, a rotation of the adjustment screw 38 makes it possible to raise or lower the cradle 37 in the stud 35 and consequently makes it possible to adjust the height of the sill carried by this support. Figures 3 and 4 show the different types of adjustment that can be made with a section of track according to the invention.
    [0022] In FIG. 3, a vertical displacement of the track panel 20 is achieved by a coordinated action on the adjusting screws 38 of the different supports of the track panel. This adjusts the height of the track panel with respect to the platform 15 by adjusting in a coordinated manner the different cradles of the different supports.
    [0023] In FIG. 4, the track panel 20 is pivoted about a longitudinal axis by adjustment of the supports on one side of the panel. This makes it possible to form a slope on the track layout by an inclination of the track. A track section according to the invention therefore allows the track to be adjusted according to two different degrees of freedom. Figures 9 and 10 show a support according to another embodiment of the figures. According to this embodiment, the stud 35 has a flat bottom and the height adjustment means are formed of a single screw 38 which is engaged in the wedge wedge 36 to horizontally move the wedge wedge in one direction or in the other. According to this embodiment, the horizontal blocking means of the cradle are formed of a tube 42 which extends between the side walls of the stud 35. FIG. 11 shows the stops 27, 28 formed under the sill 22 between which the cradle 37 is housed to block any longitudinal movement of the sill 22. Preferably, each sill comprises only two stops so that in the case where a sill is supported by two supports, 15 only the cradle of one of the two supports is engaged with the two stops to ensure longitudinal locking of the sill. FIG. 12 is a view of a metal block 50 for fixing the stud 35 in the platform 15. This metal block 50 comprises a metal plate 51 intended to come into contact with the base 35a of the support 35 and a plurality of tubes 52 welded to the metal plate 51. The length, the diameter and the number of tubes 52 are determined according to the ground. For example and according to one embodiment, a metal block 50 may comprise sixteen tubes welded to the metal plate 51. This massive metal is intended to be fixed on a platform by threshing or driving. The base 35a of the support 35 can be fixed to the metal plate 51 by gluing or by bolting means or any other equivalent means for securing the base 35a of the support 35 and the metal plate 51 of the metal block 50 Fig. 13 is a view of a guided transport section section according to an embodiment of the invention fixed on a platform 15 via the metal weirs 50 previously described. The platform 15 typically comprises an upper portion 56 of the earthworks and a backfill body 55.
    [0024] These metal beds 50 are preferably determined so that once anchored in the platform, the tubes 52 extend to the body 55 of backfill of the platform 15. In addition, preferably, the upper surface of the platform 15 is slightly inclined, for example of the order of 4% to facilitate 5 its drainage. A section according to the invention makes it possible to compensate if necessary this slight inclination of the platform by an inverse adjustment of the supports. The invention is not limited to the embodiments described. In particular, other types of architectures for the supports can be envisaged to ensure the function of vertical displacement of the cradles. According to the embodiments described, the vertical displacement of each cradle results from a horizontal or quasi-horizontal displacement of the wedge wedge. One can imagine other cutscenes to achieve a vertical displacement of the cradle relative to the stud to ensure a height adjustment and / or inclination of the track panel carried by the supports. 15
