Definitions

  • the invention relates to a method for producing a recirculating concrete sleeper, comprising the steps of: inserting prestressing steels into a sleeper mold that is continuously circulating, simultaneously automated tensioning of the prestressing steels, filling concrete into the sleeper mold, allowing the concrete to set and demoulding the concrete 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.
  • the pamphlets GB 1 357 836 A and FR 2 388 654 A relate to the production of prestressed concrete sleepers in the so-called "long fitted bed", while many sleeper shapes are arranged one behind the other and tensioned with correspondingly long tension wires, which are later severed.
  • 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 are also known with eight prestressing steels, which are simultaneously automatically tensioned and relaxed again, whereby in the previous methods with more than four tensioning wires these are then combined into bundles of at least two prestressing steels and then these bundles are 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.
  • the invention provides that in a method of the type mentioned that more than four, in particular five to eight, prestressing steels are used for a concrete sleeper, the prestressing steels are individually but simultaneously stretched simultaneously by each prestressing steel at one end over a Anchor bolt and is attached at the other end via a clamping bolt in the sleeper shape and the clamping of the prestressing steels is carried out by simultaneously pulling the individual clamping bolts.
  • This clamping operation is automated by means of a corresponding clamping device, as well as the relaxation process.
  • the axle load to be taken up by the reinforced concrete sleeper is inventively accommodated by more than four, in particular five to eight, prestressing steels.
  • the prestressing steels may be thinner than conventional prestressing steels, resulting in better load distribution.
  • a maximum of four prestressing steels were used, since the usual circulating tensioning devices did not allow the simultaneous, automatic tensioning of a larger number of prestressing steels, moreover, at more than four tensioning steels space problems that make automatic clamping difficult.
  • both ends of a prestressing steel have a thread and one end is anchored in an anchor bolt and the other end is tensioned with a clamping bolt and fixed by means of spindle nuts, which are supported on the sleeper shape. To tighten is pulled to the clamping bolt and then screwed the nut on the thread, whereby the required bias 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.
  • Fig. 1A shows a prestressing steel 1 having an anchor bolt 2 at one end to fix 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. How best in Fig. 1D can be seen in the sleepers 5 more adjacent concrete sleepers can be made in one operation.
  • 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 is carried out by simultaneously pulling the clamping bolts 3, which are fixed simultaneously by turning the nuts 4.
  • each concrete sleeper has eight prestressing steels arranged in two superimposed rows of four prestressing steels 1 each.
  • each prestressing steel 1 is tensioned individually.
  • 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.
  • the Figs. 2A to 2C, 3A to 3C . 4A and 4B each show embodiments of concrete sleepers, which have been prepared by the described method.
  • the concrete sleepers 7, 8 are constructed symmetrically. At 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. How best in Fig. 2B can be seen, the concrete sleeper 7 is constricted laterally in its central region.
  • the rail support of the concrete sleeper 7 has a lower width of about 320 to 380 mm.
  • the in the Figs. 3A to 3C shown concrete sleeper 8 has substantially the same structure as that in the Fig. 2A to 2C shown concrete threshold. 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, which has been produced by the described method, is in Fig. 4A shown in a cutaway view.
  • 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.
  • Fig. 4B Another embodiment of a concrete sleeper is in Fig. 4B shown in a cutaway view.
  • the concrete sleeper 15 has also five prestressing steels, of which three are arranged in the lower row and two in the upper row, wherein the prestressing steels of the lower and the upper row are each arranged offset from one another.
