Description

FIELD OF THE INVENTION The present invention relates to the field of transport and, more particularly, to a border slab of a station platform. Conventionally, a station comprises a transport vehicle traffic lane which is lined laterally by one or more platforms allowing passengers to get on and off a vehicle. In practice, a station platform has a width adapted to extend near the vehicle and thus limit the "gap" between the dock and the vehicle to facilitate the loading and unloading of passengers.

Referring to Figure 1, a known type of platform 1 comprises a front base 2 on which is fixed a concrete edge slab 3, of the order of 450 kg, with handling equipment. The front base 2 has an L-shaped section defining a horizontal wall 21, resting on the ground, and a vertical wall 22, the end of the edge slab 3 resting on the upper edge of the vertical wall 22 as illustrated. Figure 1. The platform 1 is positioned at a horizontal distance g of the track V, this distance g being known to those skilled in the art under the designation "dock template". As explained above, the gauge of the platform g is determined in order to allow the vehicle to be closer to the platform 1. By way of example, the gauge of the platform g is of the order of 0.935 m in the railway field. In the railway sector, during railway renewal works, maintenance equipment (cleaning machine, etc.) circulates on the railway to, in particular, renew the ballast that supports the railway. Such maintenance machines have dimensions, especially in width, greater than those of a rail passenger transport vehicle, which is problematic in stations. Also, during the renewal of the railway in a station, it is known to demolish the wharf prior to the work and then rebuild the identical after the completion of the work.

Such demolition and reconstruction operations have many disadvantages. They are expensive and block access to the dock time of work, which is a nuisance for users. In addition, the operations must be repeated at each renewal of the railway. Similarly, such demolition and reconstruction operations are also required when the dock gauge needs to be increased.

The object of the invention is therefore to remedy these drawbacks by proposing a removable edge strip for a platform that can be easily mounted on a platform structure. The invention also relates to a method of removing and installing such a border slab to facilitate the work of renewal of a vehicle taxiway or modification of the gauge of the dock.

Although the invention was originally born in the railway field, the invention relates to any type of wharf, in particular, a platform of a tram station, bus, subway, trolleybus, etc.

GENERAL PRESENTATION OF THE INVENTION To this end, the invention relates to a removable edge slab intended to be fixed on a platform structure, the slab comprising a horizontal plane body and locking / unlocking means able to allow the installation and depositing said body on said dock structure. Advantageously, the slab according to the invention can be easily mounted on a platform structure with light equipment, which reduces the cost and the installation time. In addition, the slab is advantageously removable so as not to form an obstacle during the renewal operations while being easily repositionable. Unlike the prior art, the edge slab is no longer destroyed but reused.

Preferably, the locking / unlocking means comprise at least one indexing member and a locking member adapted to cooperate by complementary shapes in a plurality of different adjustment positions in order to precisely adjust the position of the border slab on a pier. Preferably, the indexing member comprises a lumen, having an inner peripheral contour, adapted to receive the locking member having an outer peripheral contour. Advantageously, the locking member is adapted to cooperate with the indexing member in several positions offset along the width of the horizontal plane body.

According to a preferred aspect, said locking member is adapted to be fixed to said platform structure. Preferably, said indexing member and said locking member comprise complementary toothed peripheral portions in order to accurately and calibrate the horizontal plane body position on said dock structure. Preferably, the horizontal planar body is made of a composite material, preferably a composite material comprising a synthetic resin and nylon fibers. Thus the slab is light and can be handled with light gear while having a high structural strength. In addition, the slab can be colored in the mass to prevent any degradation of the color of the edge slab in case of wear.

Preferably, the horizontal planar body has a mass of less than 60 kg. Thus, the edge slab can be easily handled, especially by hand by operators. Preferably, the horizontal planar body has a length of between 2 30 m and 2.40 m and a width of between 0.90 m and 1.20 m so that the edge slab is integrated on a platform instead of a concrete slab according to the prior art of similar dimensions.

Preferably, the horizontal plane body comprises an upper face which comprises a tactile zone in order to allow a secure circulation of visually impaired persons who can thus be located on the station platform without risk.

The invention also relates to a quay comprising a quay structure and at least one removable edge slab, as presented above, fixed on said quay structure. With the wharf according to the invention, only the border slab must be removed during maintenance work, which is practical and reduces costs. Preferably, the removable edge slab protrudes from said dock structure, preferably with a projection distance of between 28 cm and 35 cm. Thus, when the border slab is removed, the space available for maintenance vehicles is greatly increased. In addition, in the case of a railway platform, such a platform makes it possible to define two templates of different values: on the one hand, a high template at the level of the border slab corresponding to the size of a rail vehicle, and on the other hand, a low template at the platform structure adapted to the template of the maintenance vehicles. Thus, during maintenance work, only the edge slab is removed to allow maintenance vehicles to perform work on the railway. While in use, the slab allows users to embark and disembark the railway vehicle in a conventional manner, the user then perceiving no difference. The invention finally relates to a method of removing and laying an edge slab comprising a horizontal plane body fixed to a dock structure by locking in a position of use, the method comprising: a step of unlocking said body the quay structure; a first step of moving said body from the use position to a storage position; a second step of moving said body from the storage position to the position of use; and 3027036 5 - a step of locking said body to the dock structure. With the method according to the invention, it is not necessary to demolish the edge slab during handling work, which reduces costs. In addition, such 5 steps of locking / unlocking and moving the edge slab are easy and allow not to prevent access to the dock during handling work. Preferably, the edge slab being in the immediate vicinity of a railway in the position of use, the method comprises a step of renewing said railway between the first and the second displacement step. Thus, the renewal of said railway can be achieved easily and for a reduced cost.

3027036 6 DESCRIPTION OF ONE OR MORE EMBODIMENTS OF IMPLEMENTATION AND IMPLEMENTATION Conventionally, a railway station comprises a railway line which is bordered laterally by one or more platforms enabling passengers to get on and off a railway vehicle. . Referring to Figure 2, there is shown a station platform 4, according to a preferred embodiment of the invention, which is located near a railway line V on which can drive rail vehicles. Subsequently, again with reference to FIG. 2, the platform 4 is described in an orthogonal reference (X, Y, Z) in which: the axis X extends horizontally along the length of the platform 4, that is to say, along the axis of the railway line V, the Y axis extends horizontally along the width of the platform 4 and is oriented from front to rear so that the front end of the station wharf 4 15 is close to the railway line V as shown in Figure 2, and - the Z axis extends vertically along the height of the platform 4 and is oriented from the bottom to the top. Subsequently, the plane (X, Y) is referred to as the horizontal plane while the plane (X, Z) is referred to as the vertical plane. In practice, a platform 4 has a width, defined along the Y axis, adapted to extend close to the railway vehicle and thus limit the "void", also called "gap", between the platform 4 and the vehicle to facilitate the boarding and unloading of passengers. Referring to Figures 2 and 3, a platform 4 comprises a platform structure 5 on which are fixed several upper horizontal slabs 6 adjacent to the length of the platform 4, defined along the axis X, so as to form a platform 4 of the desired length. For the sake of clarity, only a border slab 6 will be described later. As illustrated in FIG. 3, the platform structure 5 comprises a rear base 7 and a front base 8 to receive the edge slab 6. In this example, the rear base 7 comprises a lower rear body 71, formed of backfill, on which is positioned an upper rear support 72. Preferably, the embankment of the lower rear body 71 comprises gravel whose size is preferably between 0 and 31.5 mm while the upper rear support 72 is concrete, of preferably, reinforced concrete.

With reference to FIG. 2, the front base 8 is a prefabricated concrete structure having an L-shaped section along its length and defining a horizontal wall 81, resting on the ground, and a vertical wall 82. The horizontal wall 81 extends backward from the lower edge of the vertical wall 82. Advantageously, because of its prefabricated structure, the front base 8 can be made to the desired size and appearance. The front base 8 can thus be installed quickly with reduced equipment. The platform structure 5 makes it possible to form a horizontal support for the edge slab 6. With reference to FIG. 3, the edge slab 6 comprises a horizontal plane body 60, 15 positioned on the platform structure 5, and means of 9, adapted to fix the horizontal body 60 on the platform structure 5. As illustrated in Figure 2, the horizontal plane body 60 has a block shape defining an upper face 6A and a lower face 6B opposite to said face Upper 6A. The lower face 6B is in contact with the platform structure 5, in particular with the rear base 7 and the front base 8, when the edge slab 6 is in the position of use. Similarly, the horizontal plane body 60 has a front end 6C and a rear end 6D.

Preferably, the horizontal body 60 of the border slab 6 has a length of between 2 m and 2.40 m, preferably 2.40 m, a width of between 0.90 m and 1.20 m, preferably 1 m, and a thickness of between 5 cm and 10 cm, preferably 6 cm.

Advantageously, the horizontal body 60 is made of a composite material, for example a synthetic resin including nylon fibers in order to have a high rigidity and a high resistance to pressure. A horizontal plane body 60 made of composite material has a low weight of between 50 kg and 60 kg, preferably of the order of 60 kg, thus allowing it to be handled without heavy handling equipment, see by hand by several operators. In addition, the composite material can be colored in the mass according to different colors, in particular to aesthetically integrate the edge slab 6 in the station. Advantageously, the border slab 6 remains colored even in case of wear of its upper face 6A on which travelers travel, which is not the case with a painted slab. The upper face 6A of the horizontal body 60 is the surface on which the users of the station can move on the platform 4. In this example, the upper face 6A of the horizontal body 60 comprises a tactile zone 61, ie a surface presenting uneven relief (bumpy, grooved, etc.) to allow visually impaired persons to be located with respect to the front end 6C of the platform 4. Preferably, the tactile zone 61 extends along the length of the platform 4 to a distance of the order of 50 cm from its front end 6C as illustrated in FIG.

With reference to FIG. 2, the horizontal body 60 comprises six through holes 62 extending vertically along the axis Z to allow the insertion of locking / unlocking means 9 of the edge slab 6. Nevertheless, it goes from that the horizontal body 60 could understand a different number.

Still with reference to FIG. 2, the through holes 62 are distributed in two rows, each extending along the X axis, that is to say along the length of the edge slab 6, the two rows being offset along the Y axis, that is to say, according to the width of the edge slab 6. Nevertheless, the through holes 62 could also be distributed in a different manner in order to ensure a distributed fastening of the edge slab 6. 4, at least two through-holes 62 of the horizontal body 60 are said to be elongated and have an elongate longitudinal section extending along the Y axis 30 in order to allow the adjustment of the position of the edge slab 6 according to FIG. Y axis as will be presented later. Preferably, the two elongated through holes 62 are spaced along the X axis to increase the stability of the edge slab 6 in the locked position. Preferably, more than two through holes 62 may be elongated.

As illustrated in FIG. 3, the edge slab 6 extends projecting forwards from said quay structure 5, preferably with a projecting distance of between 28 cm and 35 cm, preferably 33 cm. In other words, the edge slab 6 is mounted cantilever so as to provide a circulation space beneath it. The edge slab 6 further comprises locking / unlocking means 9 enabling, on the one hand, to lock the horizontal plane body 60 and, on the other hand, to unlock the horizontal plane body 60 of the platform structure 5. In other words, the edge plate 6 is easily removable from the platform structure 5. In this example, the locking / unlocking means 9 comprise six screws 90 connecting the horizontal plane body 60 to the rear base 7 of the platform structure. 5. Nevertheless, it goes without saying that the number of screws 90 could be different. The screws 90 are adapted to extend into the through holes 62 of the horizontal body 60 of the border slab 6. The screws 90 can advantageously be unscrewed, which makes the locking / unlocking means 9 reversible. More preferably, each screw 90 may be associated with a washer to secure the screwing.

In order to improve the cooperation between the screws 90 and the through holes 62 of the horizontal body 60, metal reinforcements (not shown) can be mounted in each through-hole 62. Thus, the screws 90 are in contact with the metal reinforcements and not directly with the composite material of the horizontal body 60, which increases the life of the horizontal body 60.

Advantageously, the locking / unlocking means 9 advantageously make it possible to prevent tilting of the border slab 6 forward during its use.

With reference to FIGS. 4 and 5, the locking / unlocking means 9 further comprise adjustment means placed in each elongated through hole 62 of the horizontal body 60 in order to allow adjustment of the position of the edge slab 6.

3027036 10 As shown in Figure 4, the adjustment means comprise an indexing member 91, integrally mounted to the horizontal plane body 60 in an elongated through hole 62, and a locking member 92 adapted to cooperate by complementarity of shapes with said indexing member 91. In other words, the indexing member 91 is locked in translation along the X axis and along the Y axis within the elongated through hole 62. In detail, the indexing member 91 has an outer surface complementary to the inner surface of the elongated through hole 62 and an inner lumen 910 adapted to receive said locking member 92. The inner peripheral contour of said lumen 910 and the outer peripheral contour of the locking member 92 are at least partially toothed in order to cooperate by complementary shapes in a plurality of different positions distributed along the Y axis. referred, the inner peripheral contour of said lumen 910 and the outer peripheral contour of the locking member 92 have a rack structure as shown in Figure 4 whose teeth are distributed along the Y axis. In other words, the locking member 92 has dimensions smaller than those of the light 910 of the indexing member 91 in order to define several different adjustment positions in the direction Y. As illustrated in FIGS. 4 and 5, for blocking the edge slab 6, a screw 90 passes through the locking member 92, positioned in the slot 910 of the indexing member 91, in order to be received in the rear base 7. With reference to FIG. 5, in the locked position, the 25 head of the screw 90 to block the locking member 92 to prevent it from moving relative to the indexing member 91 in the vertical direction Z. In addition, thanks to its teeth , the locking member 92 prevents any translation of the indexing member 91 in the horizontal plane (X, Y).

To modify the position of the border slab 6, it suffices to remove the screw 90 in order to be able to make a relative displacement of the locking member 92 with respect to the indexing member 91 along the axis Z and thus define a new position of cooperation in the two members 91, 92. By way of example, it is illustrated in Figure 4 two 3027036 11 relative positions of the locking member 92/92 'relative to the body of indexing 91 following a displacement A of the edge slab 6. During the manufacture of a station platform 4 according to the invention, a front base 8 is positioned on the ground, in front of the rear base 7, of in such a way that the horizontal wall 81 extends at the height of the railroad V. The vertical wall 82 is placed at a horizontal distance along the predetermined Y axis GB of the railroad track V, this distance being designated as a "low jig GB" ". The low gauge GB is determined in order to allow the maintenance equipment to run on the railway line V at the platform 4. In this example, the bottom gauge GB of the platform is of the order of 1.2 m. The upper rear support 72 forms a horizontal bearing surface on which is positioned the border slab 6. More specifically, the lower face 6B of the horizontal plane body 60 is in contact with the upper face of the upper rear support 72.

The edge slab 6 is then moved on the platform structure 5 along the Y axis to the position of use, ie so that the front end 6C of the horizontal plane body 60 is at a horizontal distance along the predetermined Y axis GH of the track V, this predetermined distance GH being designated "high jig GH". The high jig GH is determined to allow the rail vehicle to be closer to the platform 4, or about 0.9 m. In addition, in the position of use, the edge slab 6 is positioned cantilevered on the platform structure 5, that is, the horizontal body 60 of the edge slab 6 extends horizontally projecting towards the railway V. The protruding distance from the horizontal body 60 corresponds to the difference between the top template GH and the bottom template GB. In this example, the projecting distance is of the order of 30 cm. Finally, the horizontal plane body 60 is locked on the platform structure 5 by screwing the screws 90 in the through holes 62.

The edge slab 6, according to the invention, can be easily integrated into any station in place of an immovable concrete slab according to the prior art, the platform structure 5 not being advantageously not modified. In addition, the edge slab 6 has no discernible change for the users, the main difference being the 3027036 12 positioning cantilever is not visible by a user walking on the border slab 6. The border slab 6, according to the invention, can be integrated visually in all 5 stations through the use of a colored composite material to obtain a wide choice of colors of edge slab 6. In addition, the composite material of the edge slab 6 being colored in the mass, the slab 6 remains colored even in case of wear of its upper face 6A, which is not the case with a painted slab.

In addition, the edge slab 6, according to the invention, makes it possible to integrate a tactile tactile zone which enables the visually impaired persons to use the station platform 4 safely. Finally, the edge slab 6, according to the invention, can be easily moved, during work, by one or more operators, with light handling equipment or by hand, without blocking access to the platform 4 during the works. These works can be of different types: renewal of the railway, modification of the high gauge GH of the dock, etc. When renewing the railway near the platform 4 according to the invention, the edge plate 20 is unlocked from the platform structure 5. For this, the screws 90 of the locking / unlocking means 9 are removed from the structure The border slab 6 is then moved easily by light handling equipment or by hand by operators from the use position to a storage position. This storage position is a prepared zone, at least temporarily, in order to allow the storage of the edge slab 6 during the renewal works of the railway line V. Once the edge slab 6 has been removed from the quay structure 5, the space available for the passage of a maintenance machine is increased and is no longer limited by the high template GH, only the low template GB to be taken into account. In this example, the available space increases by about 30 cm and allows the circulation of maintenance machines (stripping machine, etc.) to perform work on the railway, including the renewal of the ballast that supports the track railway.

After the renewal work has been completed, the edge slab 6 is moved from the storage position to the use position on the platform structure 5 in a manner similar to its first displacement. Then, the edge slab 6 is locked on the platform structure 5 by screwing the screws 90 into the through holes 62. In other words, the edge slab 6 is repositioned to its original position. The cantilevered mounting of the edge slab 6 makes it possible to benefit, on the one hand, from a large, low gauge GB allowing the passage of any type of maintenance machine and, on the other hand, from a high GH template adapted to the size of traditional railway vehicles running on the railway. The platform 4 according to the invention thus advantageously allows the renewal of the railway without demolition, but simply by dismantling and moving the border plate 6. Such an operation is fast and practical to implement since it can be made by hand by one or more operators and does not block access to dock 4 during the work. Finally, such an operation has a cost well below the costs of demolition and reconstruction of a dock.

Advantageously, in case of modification of the gauge of traditional railway vehicles running on the railway, the high jig GH of the platform 4 can be conveniently and cheaply adjusted. The low template GB is advantageously not modified.

During the modification of the high jig GH of the platform 4 according to the invention, the edge slab 6 is unlocked from the platform structure 5. For this, the screws 90 of the locking / unlocking means 9 are removed from the structure of FIG. Thus, the locking members 92 can be removed, in the vertical direction Z, from the lights 910 of the indexing members 91 in order to allow the edge slab 6 to translate in the Y direction. The edge slab 6 is moved horizontally along the Y axis easily by operators, from the old position of use, corresponding to the old high jig GH of the platform, to a new position of use, corresponding to the new high jig GH .

3027036 14 Once the edge slab 6 positioned according to the new high template GH, the slab 6 is locked on the platform structure 5 thanks to the locking / unlocking means 9. For this purpose, the locking members 92 are again 5 introduced, in the vertical direction Z, into the slots 910 of the indexing members 91 in order to block the translation of the edge slab 6 in the Y direction in a new cooperation position. The presence of teeth advantageously makes it possible to define a plurality of cooperation positions whose deviations are calibrated in order to precisely adjust the value of the high template GH.

After screwing the locking members 92 on the platform structure 5, the cooperation of the teeth of the members 91, 92 prevents any displacement of the edge slab 6. Advantageously, the platform 4 according to the invention makes it possible to carry out as well a decrease than an increase in the high GH template. According to one embodiment of the invention, the locking / unlocking means 9 are adapted to allow relative movement with respect to the platform structure 5, from 2 cm to 6 cm, preferably of the order of 4 cm. .

The platform 4 according to the invention makes it possible to modify the high jig GH of the platform 4 easily, without demolishing the wharf but simply by moving the border slab 6. Thanks to the invention, the renewal of a railway line or Template modification 25 can be conveniently made for a reduced cost. The invention has been presented for application in the railway field but it applies to any type of station platform, in particular, a platform of tram station, bus, subway, trolleybus, etc.. 30
