Definitions

  • a sole of a viscoelastic material suitably chosen, such as a dense and hard polyurethane, between the single concrete block of a monobloc sleeper or each block of concrete from a bi-block sleeper, or any concrete block from any rail support railroad, and ballast avoids the attrition of concrete and ballast as well as the compaction thereof, as well as dissipating the energy vibration generated by rolling loads, that is to say in particular of reduce noise when passing a train.
  • EP-A-0 465 390 proposes to fix such a sole to the or to each concrete block of a sleeper or any other rail support, by proposing different modes of joining, namely a projection or a casting of the visco-elastic material on the concrete, an integration of prefabricated plates of visco-elastic material to concrete, during the manufacturing the rail support, such as a cross member, by molding at least a concrete block, or by bonding such prefabricated plates on concrete, by any suitable adhesive.
  • the object of the present invention is to improve the binding a visco-elastic sole prefabricated to the concrete of a support block of rail such as a cross member, so as to improve the homogeneity and the effectiveness of fixing the footing to concrete while retaining the advantages of speed of implementation and uniformity of thickness of the sole, resulting from its direct integration into concrete molding and the prefabrication thereof.
  • the present invention also provides a support railway rail, such as a sleeper, having at least one block of concrete having in particular an upper face intended to receive at least one rail and one lower face intended to ensure the support of the block on a substrate, such as a ballast, and a sole made of visco-elastic material integrally covering this underside and intended to serve support intermediary between the block and the substrate, characterized in that concrete chippings, regularly distributed on one side of the footing facing the underside of the block, are directly and individually secured with the visco-elastic material of the sole.
  • the distribution regular gravel of the gravel face of the prefabricated plate ensures a distributed anchoring of the sole in the concrete, that is to say to fix the sole as homogeneously as possible to the concrete.
  • this fixing can be made much more resistant, in particular to shear forces, that a secure fixation by simple localized mutual embedding, on the one hand because it works the specific characteristics of the gravel and on the other hand due to the distribution of shear forces, resulting from the distribution of gravel.
  • the imprint area corresponding to the underside of the block of concrete to be produced can be defined by a wall defining the footprint, in which case the prefabricated plate is placed against this wall, during step b), before pouring the concrete into the cavity.
  • step b) is implemented by first filling the concrete footprint to constitute the underside of the block by the free surface of the concrete and then applying on it, before setting concrete, the gravel side of the prefabricated plate in operating conditions capable of causing the integration of gravel from the face graveled with concrete.
  • This smoothing is advantageously carried out by tamping, that is to say by application of pressure and preferably vibration, which have effect of causing a rise in the laitance of the concrete.
  • a railroad rail support according to the invention is characterized in that the sole has dimensions, in plan, smaller than those of the lower face of the block.
  • the mechanical resistance of the sole is improved by integrating, during step a), a reinforcement with visco-elastic material of the prefabricated plate, the rail support according to the invention then being characterized in that the visco-elastic material of the sole includes such a frame.
  • this reinforcement defines meshes of dimensions smaller than the particle size of the gravel of the prefabricated plate, that is to say chippings attached to the sole, which facilitates the implementation work of step a) according to a method consisting in fixing the gravel to the plate by partially integrating them into the visco-elastic material, this which makes the support according to the invention then characterized in that the pebbles attached to the sole protrude from the underside of the block and are partially integrated into the visco-elastic material of the sole.
  • the gravel of the prefabricated plate form therefrom a projection with a height of on the order of 50% to 95% of their height, measured perpendicular to the gravel face, so that the gravel attached to the sole is integrated into the visco-elastic material thereof over a height of the order from 5% to 50% of their height, measured perpendicular to the face bottom of the block.
  • step a it is advantageously prefabricated plate, during step a), by melting, forming and solidifying the material visco-elastic, chosen hot-melt, and we partially integrate the gravel in the visco-elastic material by sowing them on it between forming and solidification.
  • the sole includes a frame, and if this reinforcement defines meshes of dimensions lower than the grading of the gravel of the prefabricated plate, this reinforcement is opposed to the gravel thus sown between forming and solidification of the visco-elastic material pass through this material up to reach the face of the prefabricated plate intended to constitute the face support of the sole on the ballast, and thus preserves the homogeneity of this bearing face on the ballast.
  • the gravel of the prefabricated plate that is to say the gravel attached to the sole
  • the gravel of the prefabricated plate have the same nature and the same grain size than those of concrete, and leave between them spaces whose dimensions correspond as much as possible to their grain size, which on the one hand facilitates the insertion of gravel from the prefabricated plate between those of the concrete intended to constitute the block during of the pouring of this concrete and on the other hand ensures homogeneity of the distribution of gravel in concrete to the immediate vicinity of the sole.
  • the gravel of the prefabricated plate that is to say the gravel attached to the sole, cover from 80% to 95% of the gravel side of the prefabricated plate, i.e. still from the side bottom of the block.
  • any other support rail comprising at least one concrete block, namely in particular the bi-block sleepers, comprising two reinforced concrete blocks connected by a spacer, the switchgear supports, the blocks intended for receive a rail individually, and it will bring to the arrangements that are going be described the modifications necessary in each case, without going out to as much of the scope of the present invention.
  • a monobloc cross member 1 made of prestressed reinforced concrete, has the general shape of a block 2 of concrete, elongated in a direction longitudinal 3 perpendicular to the rail 4 to be supported.
  • block 2 is delimited by a lower face plane 6, longitudinal, parallel to the rolling plane 7 of the rails, this lower face 6 being embedded in the ballast 5 and resting on it, flat, by means of a sole 8 of a chosen visco-elastic material for example in accordance with the teachings of EP-A-0 465 390, and a upper face 9 which is essentially flat and parallel to the face lower 6 in the example illustrated but could present other conformations, and receives the two rails 4 directly or, as it is illustrated, via saddles 10, with elastic fixing of the rails 4 by means 11 not detailed and well known to a person skilled in the art.
  • the block 2 is also delimited by two flat longitudinal faces 12 connecting the lower face 6 to the lower face 9 by converging from the first to the second, so as to communicate to the block 2 a cross section in the form of an isosceles trapezoid, and in pairs transverse end faces 13 also flat, also connecting the lower face 6 to the upper face 9 and further connecting mutually the two longitudinal faces 12, these two faces 13 being approximately transverse and converging mutually from the face lower 6 towards the lower face 9 so that when viewed in section through a longitudinal plane perpendicular to these faces 6 and 9, the crosspiece also has a section essentially in the form of isosceles trapezoid.
  • the sole 8 presents in contact, flat, with the lower face 6 of the block 2 a flat upper face 14 integral with this lower face 6 while it presents downwards, that is to say in contact with the ballast 5, a lower face 15 also planar, parallel to the upper face 14 and close enough to it that the sole 8, considered in isolation, has the form of a plate with a thickness of the order of 3 to 10 mm, preferably around 4 mm, these figures only being indicated as a nonlimiting example.
  • the two faces 14 and 15 are connected mutually by a song 16 which is perpendicular to them and their communicates a rectangular shape which can be identical to that of the lower face 6 of block 2, that is to say in particular having the same dimensions as this lower face 6 so that the sole 8 fully covers the latter, in a manner known per se, or be approximately identical to that of the underside 6, and more precisely present dimensions of a few millimeters to those of this underside 6 so that the sole 8 covers practically the whole of it, leaving however remain a free peripheral zone 17 whose presence facilitates the manufacture of the assembly integral with block 2 and sole 8 in accordance with the present invention, as will appear below, and whose direct contact with ballast 5 presents little disadvantage in the since this zone 17 is limited to the immediate vicinity of the connection of the lower face 6 with the longitudinal faces 12 and the transverse end faces 13.
  • the plate constituting the sole 8 is prefabricated before being integrated into the concrete constituting block 2, at the manufacturing of it, but a specific method of prefabrication, constituting a preferred embodiment of the present invention, will now be described with reference to FIG. 3, as regards the prefabrication process, and Figure 4 with regard to the plate prefabricated obtained, intended to constitute the sole 8.
  • FIG. 3 shows that a plate 18 is initially manufactured having a lower face 19 and an upper face 20 flat, mutually parallel, separated by a thickness e corresponding to the thickness e of the sole 8 measured between its upper face 14 and its face lower 15, with plan dimensions which may be those of the sole 8 to be produced, or even to be much higher for correspond to the soles 8 of several sleepers 1, in which case cuts the plate 18 at any time preceding its integration, as sole 8, into the concrete constituting the block 2 of each cross member, respectively.
  • the plate 18 thus produced has dimensions in plan corresponding to several soles 8, it is then cut into a certain number of elementary plates each of which has the dimensions required to constitute a respective sole 8, as will be understood easily a skilled person. For reasons of simplicity, we will subsequently keep the same reference number 18 to designate a plate made directly to the dimensions of a sole 8 determined or a plate obtained by cutting a plate 18 corresponding to several soles 8.
  • a plate 18 thus defined, having dimensions corresponding to those of a sole 8, is integrated into the concrete constituting the block 2 of a cross member 1 to be produced, to constitute the sole 8 thereof, under operating conditions which will now be described, in reference to Figures 6 to 10.
  • flank 33 and end 34 faces, connecting in pairs, thus connect the bottom 32 to a flat, horizontal upper face 35 of the mold 29, at the level of which these flank 33 and end 34 faces define a fully open filling opening 36, rectangular like the underside 6 of the block 2 to be produced and having dimensions slightly larger than those of this face 6.
  • the mold 29 has means, not detailed, for temporarily stretching between the faces end 34 of the prestressing armatures 37 of the block 2 in compression, and may have various provisions, in particular at bottom level 32, for possibly receiving organs to be integrated to the concrete of block 2 with a view to fixing the saddles 10, in the form of inserted dowels or studs, not shown but well known of a skilled person.
  • the reinforcements 37 having been put in tension inside the imprint 31 and the other frames of block 2 to be produced having been placed also in place in this imprint 31, as well as any organ to integrate into the concrete in particular for fixing the saddles 10, we sink in the footprint 31 the concrete 38 intended to constitute the block 2, making vibrate the vibrating table 30 under the usual operating conditions, as shown in Figure 6.
  • the footprint 31 is thus substantially filled with concrete 38 which, at the end of this filling, presents a free surface upwards 39 approximately flat and approximately level with the face upper 35 of the mold 29, in the filling opening 36, as it spring of FIG. 7 which illustrates a next phase of the manufacture of the block 2.
  • This phase consists in grooming the free surface 39 in particular for the make it smooth and flat, that is to say give it the conformation of the face lower 6 of block 2 that it is intended to constitute.
  • Concrete 38, at the interior of the imprint 31 then has the shape of the block 2 to be produced.
  • This damage also has the effect of causing, if possible taking into account the composition of concrete 38, a rise in milt at the level of the surface 39, this possible rise in milt being used according to one preferred embodiments of the present invention to provide the subsequent anchoring of the plate 18 by its gravelled face 20.
  • tamping is accompanied by vibrations communicated by the vibrating table 30 and is carried out by means of a lady 40 having the general shape of a rigid plate comprising a face lower plane 41 of tamping, horizontal and having a shape rectangular plane, corresponding to that of face 6 to be produced, so as to be able to be moved towards the inside of the impression 31 by applying pressure on the face 39 until occupying with respect to the bottom 32 of the imprint 31 a position identical to that of the underside 6 of the block 2 with respect to the upper face 9 thereof.
  • Plate 40 is stiffened for example by a beam 42 which doubles it upwards, and which ensures the connection of this plate 40 to means, simply shown schematically by a vertical double arrow 43, of lifting relative to the mold 29, to clear the filling opening 36, and the descent to this mold 29, that is to say towards the inside of the imprint 31, to effect tamping the free surface 39 of concrete 38 with the application of a pressure to it.
  • a next step, illustrated in Figure 8, is itself characteristic of the implementation of the present invention and consists in deposit on the groomed free surface 39 of the concrete 38 the plate 18 of which turns the gravel side 20 downwards so that this side gravelled 20 essentially covers the free surface 39 of concrete 38, in a position substantially identical to that which the sole 8 must occupy with respect to the lower face 6 of block 2. Naturally, this deposition takes place while the tamping plate 40 is lifted.
  • gravels 44 of concrete 38 are inserted in the spaces free 28 between the gravel 27 during this phase of penetration of these last in concrete 38, as shown in Figure 5 illustrating the crosspiece 1 finished, in position of use, so that the gravel 27 are embedded in concrete 38 under the same conditions as gravel 44, and the identity of nature between the gravel 27 and the gravel 44 ensures homogeneity of concrete 38 until contact with the gravel face 20 of plate 18. It is understood, however, that concrete 38 can in addition to containing gravel with a grain size greater than that of chippings 44, in a manner known per se.
  • the continuity between the gravel 44 and 27 is ensured by the only laitance raised during the tamping illustrated in Figure 7, or by the filler material deposited on the free surface 39 between the steps illustrated in FIGS. 7 and 8 in the case where the quantity of laitance thus available would be insufficient; excess any laitance or filler material can drain upwards around the plate 18, taking into account the aforementioned dimensioning thereof.
  • the preferred choice, for the plate 18 intended for constitute the sole 8, of plan dimensions slightly smaller than those of the lower face 6 of the block 2 to be produced, that is to say those of the free surface 39 of concrete 38 inside the cavity 31, facilitates also the evacuation of air which could tend to remain trapped between the plate 18 and the concrete 38, that is to say allows to obtain a contact as intimate as possible between the concrete 38, on the one hand, the gravel 27 and, by the free spaces 28 between them, the face 20 of the plate 18, on the other hand.
  • the lady 40 is lifted and the vibration stopped, and the mold 29 is detached from the vibrating table 30 to transport it to an intermediate storage area or, as illustrated in figure 10, towards an oven to authorize or cause the setting concrete 38.
  • the molds 29 are preferably turned over, that is to say rest by their face 35 on a horizontal support, plane 45, so that the concrete 38 rests on it support 45 by means of the gravelled plate 18 and contributes, by its own weight, to preserve the integration of the gravel 27 thereof to concrete 38; however, it is not beyond the scope of this invention by leaving the face 35 of the molds facing upward during the concrete setting 38.
  • a cross member 1 according to the invention including in particular the lower face 6 is constituted by the surface 39, initially free, of the concrete 38 now constituting block 2 and the sole 8 of which is constituted by the plate 18, the gravel face 20 of which constitutes the upper face 14 and whose other face 19 constitutes the lower face 15.
  • the gravel 27, embedded both in the visco-elastic material now constituting the sole 8 and in concrete 38 now constituting block 2, provide a link regularly distributed between the sole 8 and the block 2, so particularly effective, covering the same proportion of the face lower 6 of block 2 than of the upper face 14 of the sole 8, namely in the range of 80% to 95% in the preferred implementation example previously indicated.
  • the molding imprint 31 is shaped so as to carry out the molding of the crosspiece not in an inverted position of this one but in another position, in which case one could be brought to place the plate 18 in this cavity 31 before pouring the concrete 38 into it, the gravelled plate 18 being naturally placed in the area of the imprint 31 intended to produce the lower face 6 of the block 2 of concrete and having its gravel face 20 towards the inside of the imprint 31.
