Definitions

  • the invention relates to a method for producing a concrete sleeper, comprising the following steps: inserting prestressing steels into a sleeper mold, tensioning the prestressing steels, pouring concrete into the sleeper mold, allowing the concrete to harden and dismantling the concrete sleeper.
  • sleeper molds are used, which are continuously in circulation. After cleaning the sleeper molds they are filled with liquid concrete, then they go through a vibrating station. The curing time of the filled in the emerging forms of liquid concrete can be shortened by heat, for example in a heat chamber. If the concrete has sufficient strength, the sleeper molds are raised and turned over to allow the concrete sleepers to disengage.
  • Conventional concrete sleepers usually have four embedded prestressing steels, which are arranged in two rows and at a lateral distance from each other.
  • sleepers with such a reinforcement are not or only partially suitable for high axle loads.
  • Thresholds with eight prestressing steels, which are simultaneously tensioned and released again, are also known, with the previous methods having more than four tensioning wires then being combined into bundles of at least two prestressing steels and then these bundles being stretched together.
  • the invention has for its object to provide a simple and inexpensive method for producing a concrete sleeper, which is suitable for high axle loads.
  • both ends of a prestressing steel have a thread and one end is anchored in an armature spindle and the other end is tensioned with a clamping spindle and fixed by means of spindle nuts, which are supported on the sleeper shape. To tighten is pulled on the clamping spindles and then screwed the nut on the thread, whereby the required preload is held in the prestressing steel.
  • prestressing steels with a ribbed or profiled surface are used. In such a trained surface results in a solid bond between prestressing steel and the surrounding concrete and thus a good force.
  • the invention relates to a concrete sleeper with a reinforcement of prestressed prestressing steels and possibly limp reinforcement.
  • the concrete sleeper according to the invention is characterized in that it is produced according to the method described and has more than four, in particular five to eight, prestressing steels.
  • Fig. 1A shows a prestressing steel used in the method according to the invention
  • Figure 1 B is a threshold form in a sectional side view with inserted prestressing steels.
  • Fig. 1C is a detail of a front view of the sleeper mold of Fig. 1B;
  • FIG. 1D is a detail of a top view of the threshold form of FIG. 1B; FIG.
  • Fig. 2A is a side view of a concrete sleeper according to the invention
  • Fig. 2B is a plan view of the concrete sleeper of Fig. 2A;
  • FIG. 2C is a front view of the concrete sleeper of Fig. 2A
  • 3A shows a further embodiment of a 3C concrete sleepers according to the invention.
  • Fig. 1A shows a prestressing steel 1 having an anchor bolt 2 at one end for fixing the prestressing steel 1 in a sleeper shape.
  • a clamping bolt 3 At the other end of the prestressing steel 1 is a clamping bolt 3, which has a thread on which a nut 4 is screwed.
  • Fig. 1B shows a threshold form 5 in a partially sectioned side view.
  • the inner contour 6 of the sleeper mold 5 is adapted to the shape of the concrete sleeper to be produced.
  • different types of sleepers are used, or the forms of sleepers can be modified by mold inlays or sheet metal inserts.
  • Fig. 1 D can be made in a single operation in the sleeper mold 5 more adjacent concrete sleepers.
  • the anchor bolt 2 and the clamping bolt 3 are each supported on the end faces of the sleeper mold 5.
  • the tensioning of the prestressing steels 1 takes place by simultaneous pulling of the clamping spindles, which are simultaneously fixed by turning the nuts 4.
  • each concrete sleepers on eight prestressing steels which are arranged in two superimposed rows, each with four prestressing steels 1.
  • the prestressing steels 1 are inserted into the sleeper mold 5. Subsequently, the simultaneous clamping of the Prestressing steel 1, each prestressing steel 1 being tensioned individually. Thereafter, the liquid concrete is poured into the sleeper mold 5 and compacted by shaking. Curing takes place by itself, but it can be accelerated by supplying heat. The finished concrete sleeper can then be removed from the mold.
  • Figs. 2A to 2C, 3A to 3C, 4A and 4B respectively show embodiments of concrete sleepers made according to the described method.
  • the concrete sleepers 7, 8 are constructed symmetrically.
  • To a middle, flat portion 9 on the top of the concrete sleeper 7 is followed by an oblique portion 10 laterally adjacent to a slightly inclined portion 11, the inclination of which is about 1:40 in the illustrated embodiment.
  • This is followed by an inclined section 12, the end portion 13 of the concrete sleeper 7 is flat.
  • the concrete sleeper 7 has eight prestressing steels 1.
  • the concrete sleeper 7 is laterally constricted in its central region.
  • the rail support of the concrete sleeper 7 has a lower width of about 320 to 380 mm.
  • the concrete sleeper 8 shown in FIGS. 3A to 3C has substantially the same structure as the concrete sleeper shown in FIGS. 2A to 2C. Since both concrete sleepers 7, 8 each have eight embedded prestressing steels, they are able to absorb high axle loads.
  • FIG. 4A Another embodiment of a concrete sleeper made by the described method is shown in a sectional view in FIG. 4A.
  • the concrete sleeper 14 has five prestressing steels, four of which are arranged like the corner points of a square and a fifth prestressing steel in the middle.
  • Another embodiment of a concrete sleeper is shown in a sectional view in FIG. 4B.
  • the concrete sleeper 15 also has five prestressing steels, three of which are arranged in the lower row and two in the upper row, with the prestressing steels of the lower and upper rows being offset from each other.

Abstract

Procédé de fabrication d'une traverse en béton, comprenant les étapes suivantes : mettre en place des aciers d'armature dans un moule à traverse, serrer simultanément et de façon automatisée des aciers d'armature individuels, remplir le moule de béton, laisser durcir le béton, démouler la traverse en béton. On utilise pour une traverse en béton plus de quatre aciers d'armature, notamment cinq à huit, et les aciers d'armature sont serrés individuellement mais néanmoins simultanément.
