Definitions

  • the present invention relates to a sleeper railway, comprising at least one rigid block, especially concrete, with a lower face substantially flat intended to rest on a support, a upper face intended to receive at least one rail longitudinal, and four peripheral faces which connect the upper side to the lower side and each of which has a substantially lower bottom flat, with two peripheral faces longitudinal whose lower parts converge mutually down and from two peripheral faces transverse whose lower parts converge mutually downward, said block being provided with a waterproof bootie wrapping its underside and lower parts of its peripheral faces and having for this purpose a flat bottom having a face upper substantially flat along the lower face block with interposition of an elastic sole, especially in compression and shear, and a flange continuous device bordering this bottom and presenting a upper edge at least approximately parallel to this substantive, at a level higher than that of the parties bottom of the peripheral faces of the block, this rim having four substantially flat internal faces including each runs along the bottom of one side respective block device.
  • Such ties are frequently used to install a track without ballast, for example in or on a structure such as a tunnel or a viaduct, offering as a support to the sleepers a raft or a slab.
  • the sleepers are brought to the installation site already provided with their slippers, temporarily retained by links, then we place them in their position definitive with respect to the medium, in particular by posing by the slippers on a temporary raft and adjusting their position by means of appropriate devices, and finally we fill a game with concrete or the like remaining between the slippers and the support as well as from one liner to the other, drowning the frame and slippers without however exceeding their upper edge.
  • the provisional retaining links slippers are cut flush with the concrete and the slippers only provide a mechanical connection between the blocks of sleepers and support by authorizing, together with the elastic sole generally provided, a possibility relative elastic deflection.
  • each slipper is made in one piece of material with elasticity of rubber, in dimensions as it comes to apply firmly, by the internal faces of its rim, on the parts devices of the block, it being understood that the rheostatic thrust applied by the concrete firms this support.
  • the block is released from the liner which is left in place and in which we introduce a new block.
  • a first difficulty appears during the fabrication of sleepers and installation of slippers on the blocks, in the workshop.
  • the block making technique usually by concrete molding, does not allow to respect very strict manufacturing tolerances while the molding techniques for materials presenting the elasticity of the rubber makes it possible to communicate to slippers of precise dimensions.
  • the material constituting the slippers presents great vulnerability to punching and shifting on the support or on the temporary raft, and tears of some slippers may occur.
  • the push rheostatic applied to the slipper causes a deformation of it, which is pressed under a more or less controlled pressure, generally strong, on the block, to the point that it can result in a total impossibility for the block to play elastically at inside the bootie, both in the direction of the height than in a plane parallel to the support, which practically cancels the amortization effects generally sought by means of the bootie, and may cause rapid deterioration of it.
  • an object of the present invention is to remedy these drawbacks and, to this end, the present invention offers a cross member of the type indicated in the preamble, by further characterized in that the liner is formed a substantially rigid shell carrying, between each inner side of the bootie and the lower part of the respectively corresponding peripheral face of the block, a respective flat segment, elastic in particular compression and shear, placed in prestress elastic compression and shear.
  • the block does not come into contact with the liner, which can be considered as forming a rigid whole with the filling concrete and with the support, so that all the elasticity of the block support in relation to the support and all vibration damping effects suffered by the block during the passage of trains are insured by the segments and the sole alone, that is to say without the shoe plays a role for this purpose other than that a rigid counterpart, integral with the support.
  • a substantially rigid liner offers better resistance to sliding or punching on any type of support, i.e. retains its seal under conditions in which a traditional slipper, in material elastic, may tear or puncture.
  • the substantially rigid liner resists rheostatic thrust of this concrete so that the adjustment precise and adjustment of mutual support constraints between the inner sides of the liner and the lower areas peripheral faces of the block, via segments, is kept and that, subsequently, the block can move elastically in good conditions determined, inside the liner, when passing trains.
  • each segment is detachably retained in the liner and independent of the block, for example the fact that each internal face has a peripheral segment retaining shoulder respective against a relative slip, said shoulder being dimensioned weakly enough to do not come into contact with the block, and / or each side internal and the respective segment present means distributed detachable mutual latching, for example under the shape of a groove parallel to the upper face of the bottom of the liner, arranged on each internal face, and splines fitted additionally on each segment.
  • the sole is retained removably in the liner and independently of the block and we can even foresee that the crosspiece has a shim inserted between the sole and the face upper bottom, detachably retained in the liner and independent of the sole, which allows to intervene at the same time on the thickness of the hold, considered to be substantially incompressible, and on characteristics of the sole to choose the support characteristics of the cross member down in the slipper.
  • each internal face forms in the immediate vicinity of the upper face of the bottom, at a level lower than that of a lower limit of the respective segment, a sole retaining shoulder and, if applicable, of the shim against sliding relative, said shoulder being dimensioned sufficiently weakly so as not to come into contact with the block.
  • the shoulders thus provided on the inner faces of the boot edge do not enter not in contact with the block is understood by reference to normal conditions of use of the sleeper.
  • the shim of possible thickness present advantageously in contact with the sole a roughness obtained by a relief such as streaks, spikes diamond or spikes, which prevents slipping the sole on the wedge.
  • the use of a rigid material to make the liner also makes it possible to provide reliefs closely located inside of it, to come into contact with the block when introducing this one in the slipper, so as to serve as a guide positioning, then either break or wear out first pass of a train so as not to hinder the functioning of the elastic segments and the sole elastic.
  • Dissociating, in accordance with this invention, on the one hand the elastic segments in particular in compression and shear and on the other hand the slipper proper, meanwhile substantially rigid, also offers the possibility to choose at will the mechanical characteristics of the segments, i.e. their nature, their thickness, possibly their conformation in contact with the lower part of the peripheral face of the corresponding block respectively, and in particular to adapt these characteristics to the position segments.
  • the segments corresponding to the longitudinal faces have a stiffness greater than that of the segments corresponding to the transverse faces so that the segments corresponding to the longitudinal faces primarily provide for amortization and that segments corresponding to the transverse faces ensure simply a resilient support of the block vis-à-vis the slipper and, through it and concrete filling, relative to the support.
  • each segment has a discontinuous structure in contact with the lower part of the peripheral face respectively block correspondent, for example in the form of a grooving parallel to the upper face of the bottom, which facilitates the work of the segment in shearing elastic during vertical elastic deflections of the block, also mainly taken up by elastic compression by the sole, for a constraint of determined elastic compression of the segments between the block and liner.
  • a seal is removably retained on the liner, for example by providing that the joint seal and the upper edge of the boot edge have mutual interlocking means, but the joint can also be made by casting a bead of a suitable material between the upper edge of the rim of the liner and block after fitting the liner on the block.
  • the liner internally, between the internal faces and the upper edge of its rim, and the block, externally, above the lower parts of its faces peripheral, present facets appreciably planes arranged opposite, without mutual contact, and forming a respective flare upwards, each side device of the block present, above the facet respectively corresponding, an upper substantially flat, and the upper parts of the faces longitudinal devices and upper parts transverse peripheral faces, respectively, converge upward and connect to the respective facet along a peripheral edge of the block, at least approximately parallel to the face bottom of the block and located at a level below that of the upper edge of the boot edge, such so that the gasket is supported so waterproof on the upper parts of the faces block devices.
  • the bottom of the liner has a convex underside, which helps evacuate the air from the bottom of the liner when putting it on place and vibration of the filling concrete.
  • the underside of the bottom has an area flat central unit, parallel to its upper face, for authorize a press set on the support or on a reinforcement covering it, during installation sleepers before pouring the filling concrete, and also constitute an area at the bottom of the boot thicker, better resistant to sliding and upon punching, and an ascending peripheral zone towards the edge of the liner from said area central to ensure the evacuation of air.
  • the rigidity of the slipper without having to use a large wall thickness for this one providing that the liner has externally reinforcing ribs.
  • anchoring means for retaining means and / or positioning of the liner, and with it of the cross, in relation to the support, in particular before and during the setting filling concrete.
  • anchoring means for retaining means and / or positioning of the liner, and with it of the cross, in relation to the support, in particular before and during the setting filling concrete.
  • Reinforcement ribs can be oriented longitudinally and / or transversely, in particular perpendicular to the top edge of the rim, along of it and when the underside of the bottom has a flat central area and a peripheral area ascending to the edge of the bootie from this central area, they can also extend under this ascending peripheral zone, so as to extend coplanar with the aforementioned planar central zone and increase the support surface of the liner by example on a reinforcement superimposed on the support, before the placement of filling concrete.
  • the reinforcing ribs can extend peripherally around the liner and, in particular, one can advantageously provide that one reinforcing ribs extends continuously around the edge of the liner, substantially parallel to the upper face of the bottom, at a level lower than that of upper edge of the rim and corresponding substantially to that of an upper limit of the segments, to serve level reference for the casting of a material of connection of the liner with the support, namely in practice filling concrete.
  • This arrangement allows precise adjustment of the level of the filling concrete, or other material of connection of the liner with the support, with respect to segments, so that the rheostatic thrust of the concrete does not apply to the cantilever effort shoe by compared to the segments, above these, which could cause sagging or even breakage, of the wall of the liner at this level and a blocking of the block in the liner, or conversely that the concrete filling does not reach a level insufficient, thus causing a distribution of forces between the liner and the filling concrete, and indirectly between the block and the liner by through the segments, on a surface insufficient at the risk of causing excess constraints.
  • Such an arrangement further allows avoid any risk of concrete overflowing filling above the upper edge of the bootie, with risk of penetration inside of it, which would create hard support points between the block and the slipper and would harm the elasticity of mutual support by through the segments and the sole.
  • this invention can also be applied to sleepers called “monobloc”, comprising a single block provided with a copy of said liner, only to so-called sleepers “biblock” comprising two transversely extreme blocks or “blochets” each of which is provided with a copy of the said slipper and which are mutually connected secured by a rigid transverse spacer, generally metallic, this possibility of adjusting with precision the level of the filling concrete compared at the upper edge of the bootie offers an advantage additional in the case of such a bibloc cross also authorizing the respect of a spacing predetermined, or exceeding a predetermined threshold, between the spacer and the filling concrete.
  • the hull of a cross member the invention is carried out in one piece, for example by molding of a thermoplastic material, or of a resin concrete, but you can advantageously constitute a tight, substantially rigid assembly, of several watertight partial shells, substantially rigid, for example produced by this means.
  • the shell may consist of two watertight half-shells, substantially rigid, each of which corresponds to a respective half of the block considered towards transverse and which are assembled mutually, of tight and substantially rigid, along a plane longitudinal, which is particularly suited to the case of a short block in transverse direction, that is to say of a block of a bibloc crosspiece.
  • the hull is consisting of two watertight half-shells, substantially rigid, each of which corresponds to an extreme zone respective block considered in transverse direction, and a watertight, substantially rigid chute, which corresponds to an area of the block located between said areas extremes of it and which is assembled at each of half-shells, in a tight and substantially rigid manner, the along a respective longitudinal plane.
  • half-shells used in the two cases can be identical, which allows the use of standard half-shells to make facing all situations, putting them together mutually either directly or through a chute of appropriate size according to the block dimension.
  • the partial shells are mutually assembled by interlocking, namely of preferably in a transverse direction, and clamping mutual, which provides a possibility of adjustment of the transverse dimension of the shell in according to the manufacturing tolerances of the block to which it is intended, it being understood that these tolerances are at most of the order of a millimeter.

  • the ribs 54 have means, such as notches 59, allowing the liner 20 to be anchored on the frame 58, at means of links then embedded in the filling concrete 49, or on other reinforcements provided for in inside of this concrete, or even on means of positioning of sleepers 1 in relation to others and relative to the support face 7.
  • the ribs 54 bypass the connection of the rim 23 of the liner 20 to the bottom 21 of this and extend under the peripheral zone 55 in presenting downward a respective edge 60, planar, coplanarly extending the central area 57 of the face lower 56.
  • this edge 60 bends in quarter circle upwards and, along the panels 24, 25, 26, 27 of the rim 23, the ribs 54 are delimited by an edge located in a respective geometric plane parallel to plane 3 with regard to the ribs of the panels 24 and 25, or in plane 10 with regard to ribs of panels 26 and 27.

  • the rigid shell forming the liner 20 according to the present invention can be carried out of a part, not shown, or, preferably, be made by tight assembly, substantially rigid, of several partial shells themselves waterproof and substantially rigid, as illustrated.
  • the shell forming the liner consists of two half-shells watertight, substantially rigid 61, 62, of which each corresponds to a respective half of block 2 considered in transverse direction, that is to say at one halves of block 2 separated by plane 10 relative to to which the two half-shells 61, 62 are mutually symmetrical, except for the presence of the notch 35 on one of the two, namely the half-bug 62 in the illustrated example, and along which these two half-shells 61 and 62 are mutually joined and assembled mutually.
  • each of the half-shells 61, 62 has a front face along the plane 10 respective plane 63, 64, advantageously defined not only by a song from the panel part 24, 25 respectively corresponding and from the bottom part 21 respectively, but also by a respective rib 54 directly adjoining the plane 10 when the two half-shells 61, 62 are assembled mutually.
  • the front faces 63, 64 include means mutual interlocking in direction 4, in the form a continuous rib 65 arranged on one of the faces frontal 63, and more precisely on one side of the edge upper 32 compared to plane 3 on the other side of this upper edge with respect to this plane, namely on the edge of the corresponding part of panel 24, edge of the corresponding part of the bottom 21 and the song of the corresponding part of panel 25.
  • the other front face 64 has a groove or groove 66 stretching continuously on the song of the parts respective panels 24 and 25 and bottom 21, on one side of the upper edge 32 with reference to plane 3 to the other side of this upper edge 32 in reference to this plan.
  • the dimension of the rib 65 and of the throat or groove 66 in direction 4 is chosen sufficient to allow a slight tolerance in the relative positioning of the two half-shells 61 and 62 following this direction, depending on tolerances allowed for block 2, so that we can not only assemble the slippers 61 and 62 in one position in which their front faces 63 and 64 are mutually contiguous along plane 10, in particular at the respective ribs 54, respectively adjacent to this plane, but also in a position in which a gap remains between the faces frontal 63 and 64 while retaining a nesting tight of the rib 65 in the groove or groove 66.
  • the half-shells 61 and 62 can be assembled by different means, including by clamping at the ribs 54 adjoining immediately plane 10, for example by pinching these two ribs 54 towards each other by means of elastic clamps of known type, overlapping the edges of these ribs, or by screwing or riveting these ribs between them.
  • the segments 28, 29 corresponding to the panels 24, 25 thus subdivided due to the realization of the liner 20 in the form of two half-shells can be each, in one piece, or also be subdivided into two halves, mutually contiguous on along plane 10, as illustrated in the figures.
  • the bootie can also be made up of more two partial hulls, but we prefer to reserve a such a solution in the case of a bootie intended for a monobloc cross member, fitted with a single copy of this liner, as illustrated in Figures 10 to 13 to which we will now refer, being understood that we could also adopt in such a case a liner formed by two half-shells, or a liner monobloc.
  • the crosspiece has great similarities with one of the blocks 2 of a biblock cross member 1, found in Figures 10 to 13, as far as they are relevant, the same references as in Figures 1 to 9, however incremented by 100, for components or parts of matching components.
  • the main difference between the cross monobloc 101 and the bibloc crosspiece 1 resides in the fact only one block 102, for example in reinforced concrete prestressed, receives the two rails 111 and presents by therefore for this purpose an appropriate dimension following transverse direction 104, in particular at its upper face 108 suitably shaped. More precisely, between two extremes mutually symmetrical with respect to plane 109 and corresponding to upper faces 8 of the two blocks 2 of the crosspiece biblock 1, this upper face 108 has an area planes perpendicular to plane 109 and parallel to the non-referenced flat underside of the cross 101, at any point comparable to the face lower 6 of a block 2 except that it spans the entire dimension of the cross member 101 perpendicular to the plane 109.
  • the upper face 108 of block 102 is connected to its underside not referenced by four peripheral faces 116, 117, 118, 119, each of which has the same pan subdivision upper, lower pan and intermediate facet than external peripheral faces 16, 17, 18, 19 of a block 2 and which correspond substantially to the latter if this is that the faces 118 and 119 are identical, mutually symmetrical with respect to plane 109, and that the faces 116 and 117 overlap the plane 109 at which they are perpendicular and relative to which they are respectively symmetrical.
  • the liner 120 presents all the provisions that have been described about the liner 20, and in particular the ribs external peripherals 150, 152 which correspond to ribs 50 and 52, respectively, ribs 153 and 154 which correspond to the ribs 53 and 54, respectively, and a bottom bottom face centrally planar and peripherally convex; to the high, it has a peripheral upper edge 132 continuous, suitable for receiving a seal also continuous, not shown, corresponding to the joint 34 and, internally, it presents all the provisions described about the liner 20 and in particular the elastic segments in compression and shear, of which only the segments 138 and 139 corresponding to segments 38 and 39 and filling internally the panels 125 and 126 corresponding to the panels 25 and 26, it being understood that panels 124 and 127 corresponding to panels 24 and 25 carry also, internally, such segments.
  • segments such as 138 corresponding to panels 124, 125 subdivided due to realization of the hull 120 by assembling three partial shells 161, 162, 167 can be produced respectively of a piece on all three partial hulls, or present the same subdivision along plans 110.
  • segments such as 138 and 139 can almost completely cover the pan respectively corresponding, as illustrated, or cover it only partially, evenly, in the form of several respective elementary segments mutually disjoint, spread over this section and retained from removably on it for example by one any of the procedures outlined for the segments 37, 38, 39, 40.
  • the liner 120 also includes internally, on the upper face of its bottom 121, also subdivided according to plans 110, a sole 133 at all points similar to sole 33 and advantageously based on the upper face of the bottom via a wedge of thickness not referenced, but this sole 133 is advantageously made in one piece for the three partial hulls 161, 162 and 167.
  • liner 120 is dimensioned so as never to come into direct contact with the block, 102 in this case, under conditions normal operating conditions, i.e. so that the supports of block 102 on the liner and, through him, on the filling concrete 149 ensuring its connection rigid with the support face 107 are effected exclusively via sole 133, opposite which the shim behaves mechanically as the bottom would behave directly of the liner itself, and through the segments such as 138 and 139, under conditions authorizing a some elastic travel in all directions, with possibility to choose the characteristics of segments such as 138 and 139 so as to provide an effect depreciation by means of segments which like the segment 139, lining the longitudinal panels 126 and 127 by ensuring a simple elastic support effect on the through segments such as segments 138, which line the transverse panels 124, 125.
