Definitions

  • the present invention relates to a railroad cross member consisting of two reinforced concrete blocks connected by a metal spacer, each of the concrete blocks having two shoulders for a rail.
  • the spacer and the reinforcements of each of the two concrete blocks of a sleeper are formed from several elements which are free relative to each other, the aforementioned reinforcements generally being each made up of a reinforcement.
  • a spiral arranged around the spacer of a lower frame made up of steel strands, substantially parallel to the sole of the concrete block and to the longitudinal axis of the spacer, joined together by transverse welded strands and an upper frame made up of steel strands, substantially parallel to the upper face of the block and extending along the longitudinal axis of the spacer, these latter strands also being joined together by transverse welded strands.
  • crosspieces have, on the one hand, the disadvantage of requiring, for their manufacture, the manipulation and the precise positioning in the molds of the various spare parts forming the reinforcements of the concrete blocks and the spacer and, on the other hand share, the disadvantage of causing a scrap which can be significant and which is due either to a bad installation of the aforementioned spare parts in the molds, or to the accidental displacements of these last in the molds during the pouring of the concrete.
  • the object of the invention is to remedy these drawbacks and to provide a cross member, the production of which is greatly simplified compared to that of known cross members, and this, thanks to a reduction, during the casting of the cross member, of more than 50%. the number of spare parts that make it up and whose quality is better and more constant than that of known sleepers due to the extremely precise positioning of the spacer and the reinforcements of the concrete blocks.
  • the reinforcement of each of the two aforementioned concrete blocks is fixed to the spacer connecting the latter.
  • the reinforcement of each of the two aforementioned concrete blocks is not in contact with the part of the abovementioned shoulders embedded in the block to constitute their anchoring.
  • the reinforcement of each of the two aforementioned concrete blocks comprises a helical reinforcement disposed around the aforementioned spacer and, on either side thereof, a reinforcement lower and an upper frame essentially consisting of steel strands extending along the longitudinal axis of the spacer and regularly distributed below and above said spacer.
  • the invention also relates to a method of manufacturing the aforementioned crosspiece.
  • said method consists in depositing in two openings provided in the bottom of each of the two molds, in which the two aforementioned concrete blocks are formed, a pair of shoulders, part of which extends outside the mold to form the shoulder of the rail itself and the other part of which extends inside the mold to form the anchoring of the shoulder in the concrete block, to deposit the spacer and the reinforcement each of the concrete blocks, which constitute a single element, in the molds which have in their faces turned towards one another an opening calibrated to allow the introduction of the spacer of said element by locating the position of the latter exactly relative to the bottom of the molds, a mark being advantageously provided on the spacer to locate the element exactly relative to the molds in a direction parallel to the longitudinal axis of the spacer, to close the open ure calibrated abovementioned by the inside of the molds, pour the concrete, vibrate it and unmold the crosspiece, by turning the molds.
  • Figure 1 is an elevational view showing, in broken lines, one of the concrete blocks of the sleeper according to the invention and, in solid lines, the two shoulders anchored in the block, the reinforcement of said block and, with partial breakage , the crosspiece spacer partially embedded in the block.
  • Figure 2 is a sectional view along line II-II of Figure 1.
  • FIG. 3 is a view in elevation and in section of the casting mold of one of the concrete blocks of the cross member in which the two abovementioned shoulders have been placed and the cross member assembly of the cross member and frame of said block, before casting concrete, in accordance with the process according to the invention.
  • Figure 4 is a view similar to Figure 2 and shows a variant of connection of the frame of a block to the spacer of the crosspiece.
  • the railroad cross member consists of two reinforced concrete blocks 1 connected by a metal spacer 2 in the form of an angle iron, each of the blocks 1 comprising two shoulders 3 intended to be arranged on both sides. other of the shoe of a rail (not shown) to prevent any lateral movement of the latter and intended to cooperate each with a toad (not shown) associated with the shoulder and the shoe of the rail to hold the shoe of the rail against the corresponding block of the crosspiece.
  • the frame 4 of each of the two concrete blocks 1 of the cross member is fixed to the spacer 3 connecting the blocks so that the frames 4 and the spacer 3 form a rigid and non-deformable assembly.
  • the anchoring tabs 5 of the shoulders 3 are profiled, as shown in FIG.
  • the armature 4 of the blocks 1 is not in contact with the anchoring lugs 5 of the shoulders 3 so that the vibrations undergone by the latter and by their lugs 5 are not directly transmitted to the armature 4 of the blocks 1, which has the advantage of avoiding cracking of said blocks.
  • each of the concrete blocks 1 is constituted by a helical frame 6 arranged around the spacer 2 and a lower frame 7 and an upper frame 8 arranged on either side of said spacer .
  • These frames 7 and 8 each comprise steel strands 9 which extend along the longitudinal axis of the spacer 3 and which are regularly distributed below and above it.
  • the steel strands 9 of each of the reinforcements 7 and 8 are joined together by at least two steel strands 10 which extend transversely to the longitudinal axis of the spacer 2 and which are welded to the steel strands 9 at each crossing point 11 of said strands 9 and 10.
  • the helical frame 6 is, as shown in Figures 1 to 3, in contact, on the one hand, with the upper edge 12 of the spacer 2 and is welded thereto in at least two places 13 and, d on the other hand, with at least two of the steel strands 9 forming part of the aforementioned lower reinforcement 7, the reinforcement 6 being welded to each of these steel strands 9 in at least two places 14.
  • the upper reinforcement 8 is located at a distance from the helical frame 6 and is fixed to the bottom frame 7 by two stirrups 15 which are welded, at 16, to at least two steel strands 9 from each of the frames 7 and 8.
  • the method of manufacturing the cross member described above and which is illustrated in FIG. 3 consists in placing in two openings 17 formed in the bottom 18 of each of the two molds serving to form the two blocks 1 of a cross member, a pair shoulders 3 whose anchoring lugs 5 extend inside the mold, to deposit the spacer 2 of the crosspiece, to which the reinforcements 4 for the blocks 1 are fixed in the molds through a calibrated opening 19 provided in the walls 21 of the molds facing one another, these openings being arranged to locate automatically and correctly the spacer 2 and the frames 4 relative to the bottoms 18 of the molds.
  • a mark 20 is provided on the spacer 2 to allow the correct location of the spacer 2 carrying the frames 4 in the molds, in a direction parallel to the longitudinal axis of the spacer 2.
  • each of the calibrated openings 19 is closed using a plate 22 applied to the internal face of the wall 21 of the mold, the concrete is poured, the latter is vibrated and the crosspiece is demolded , by turning the molds over.
  • stirrups 15 which join the lower 7 and upper 8 reinforcements forming part of the reinforcement 4 of a concrete block 1, to the angle constituting the spacer 2 of the crosspiece, this fixing of the stirrups to the spacer being effected by welding at points 23.
