Definitions

  • the invention relates to a method for producing a ballast-free track superstructure, wherein a continuous concrete slab is applied to the subgrade, the track yoke formed from rails and sleepers is supported on the concrete slab, and the threshold space above the concrete slab between laterally raised concrete edge beams of the concrete slab with pouring Pouring concrete.
  • the continuously flat concrete slab is first poured, then the track yoke (preassembled unit made of rails and sleepers) is transported by means of portal cranes that are supported on the base of the concrete slab and placed on the concrete slab. Then, if the concrete surface is not sufficiently precise, the track yoke is adjusted in height, inclination (eg transverse inclination in curves) and possibly lateral position, using hand winches or the like. Then a side formwork is installed on both side edges of the concrete slab and the threshold space is poured out. For this, the concrete from the side next to the concrete sub-slab on the ground, possibly on a neighboring track, transport and concrete feeding devices, fed to the threshold space.
  • the track yoke preassembled unit made of rails and sleepers
  • a transport container is lifted over the track yoke to be cast by a delivery mixer by means of a crane, and then the transport container is emptied.
  • the concrete has so far been redistributed manually and, if necessary, solidified with hand-held vibrators.
  • the side formwork must be removed again. From the magazine “Eisenbahningenieur" 1988, Issue 9, pages 438 - 447, it is known to have the large lateral protrusion of an underneath rolled concrete base layer of caterpillar or wheel-guided construction machines used for the manufacture of the support plate and the laying and concreting of the track yoke.
  • side formwork must still be provided, which must be assembled on the rolled concrete base layer before the pouring of the supporting plate, dismantled after the pouring concrete has hardened and cleaned if necessary for the next use.
  • the object of the invention is to simplify the method of the type mentioned.
  • edge beams are designed in such a way that, after they have hardened, they can be loaded by track-laying machines which are supported on both edge beams.
  • the production of the corresponding load-bearing edge beams does not mean a noticeably greater production effort, since the concrete paver to be used for this purpose can only be modified accordingly.
  • the threshold gap can be poured with the pouring concrete in a single step.
  • the two edge beams are readily accessible for auxiliary devices for carrying out the subsequent method steps with the advantage of precise height and side alignment, so that on the one hand the need for a second track next to the track superstructure to be manufactured or the need for one Auxiliary lane is omitted.
  • the subsequent process steps in particular the pouring and hardening of the pouring concrete, can be carried out largely automatically. Due to their height, which significantly exceeds the thickness of the concrete slab, the edge beams are still sufficiently load-bearing, even with a relatively small width, so that the overall width of the concrete slab including the edge beams can advantageously be small (tunnel construction!). On or next to the edge beams, if necessary, transport devices can also be used to transport the track yoke here, so that the gantry cranes that were customary up to now can be omitted under certain circumstances.
  • a track yoke adjusting device which is supported on the two edge beams and is preferably movable on the rails of the track yoke.
  • the Gleisjoch adjustment device is therefore supported on the two edge beams during adjustment, which ensures a secure stand and quick and precise side and height adjustment of the Gleisjochs.
  • the threshold gap is unaffected by any parts of the adjustment device. This makes pouring out easier. Also, the unscrewing of the threaded spindles required according to US-A-4 652 495 after pouring out and shortly before complete hardening is omitted.
  • the Gleisjoch adjustment device could drive with appropriate chassis between the adjustment locations with appropriate chassis on the edge beams;
  • the method of the Gleisjoch adjusting device on the rails is particularly preferred, which is supported with its sleepers directly on the concrete slab before the adjustment and is fixed after the adjustment by means of quick-setting concrete that is introduced between the sleepers and the concrete slab in places. This measure ensures a particularly simple, mechanically robust construction of the adjustment device.
  • An automatic filling of the threshold interstices is achieved according to the invention for the first time by using a concrete paver which is supported on the edge beams, preferably movable on the edge beams, to fill in the threshold gaps.
  • the previously practiced manual concrete filling which requires a lot of work, is now no longer necessary.
  • the work accuracy especially to maintain a specified installation height, is great. Maintaining a prescribed installation height (in particular 15 cm above the underside of the threshold ⁇ 1 cm) is essential in order to maintain a sufficient distance from the rails on the one hand, and on the other hand to allow the space between the rails to be navigable.
  • a concrete paver is used which simultaneously fills several threshold gaps.
  • a second layer of sound-absorbing lightweight concrete is applied to a first layer of concrete. This measure contributes to noise reduction.
  • filling concrete maker can simultaneously apply the first concrete layer in the first space and the second layer in the second space on the previously poured first layer.
  • a vibrating device which is supported on the edge beams and compresses the concrete be used.
  • This vibrating device can be part of a concrete paver already specified above.
  • the spindles for height and inclination adjustment of the sleepers which were previously used in the sleeper bodies, are spared if the adjusting device according to the invention, which is supported on the edge beams, is used and the procedure is such that After adjusting and before pouring, the track yoke is fixed in place with quick-setting concrete that is placed between the sleepers and the concrete slab.
  • the invention also relates to a device for adjusting the track yoke in the case of ballastless track superstructure.
  • This is identified by a frame, at least one undercarriage, preferably track undercarriage, which is attached to the frame in a height-adjustable manner between a lower end position and an upper end position, at least one track adjusting device held on the frame and support elements arranged on the frame, the frame in the upper end position of the at least one undercarriage over the Supporting elements supported on the edge beams of the concrete slab, in contrast, in the lower end position of the undercarriage, its support elements are lifted off the edge beams and can thus be moved.
  • a simple construction of the device is ensured by the fact that at least one bearing beam parallel to the threshold for two track wheels is attached to the frame so as to be height-adjustable.
  • At least one track crane preferably with a trolley parallel to the sleeper, be arranged on the frame.
  • At least a part of the support elements be provided with a foot part which overlaps one of the edge beam edges. It is particularly preferably provided that a section of the foot part protruding over the edge beams runs obliquely downwards in the direction of the formation.
  • this configuration results in an effective transfer of lateral forces during the adjustment (parallel to the threshold direction); on the other hand, you get a kind of self-adjustment of the frame when lowering onto the edge beams.
  • the invention further relates to a device for pouring out the threshold spaces in the case of ballastless track construction for carrying out the method specified above.
  • This device which enables largely automatic filling of the threshold gap, is characterized by a frame, at least one undercarriage arranged on the frame and movable on the edge beams, at least one concrete storage container arranged on the frame, at least one concrete feed device connected to the container for pouring the concrete into the threshold space, if necessary at least one concrete compacting device, preferably vibrating bottle device, which is attached to the frame in a height-adjustable manner between a lower end position and an upper end position, in the lower end position the concrete compacting device extends into the threshold space and is lifted out of the threshold space in the upper end position so that the frame can be moved.
  • the at least one undercarriage can be moved on the edge beam, preferably in the form of a crawler track undercarriage.
  • the concrete feed device has at least one filler box, which is attached to the frame in a height-adjustable manner between a lower end position and an upper end position, the filler box in the lower end position reaching into the threshold space and in the upper end position the threshold gap is lifted out.
  • the at least one filler box is designed without a box bottom.
  • the box side walls ensure that even if the concrete is fed at a high rate, it will only get into the threshold space and not, for example, onto the concrete sleepers or rails. Means Appropriate level or time control ensures that exactly the required amount of concrete is supplied.
  • the filler box is designed with at least one closable delivery opening in the box bottom. This measure enables particularly precise concrete metering, since the concrete inflow can be started and interrupted immediately and without delay. Since the bottom of the box matches the level of the poured concrete, excess concrete can be retained in the box by closing the discharge opening.
  • closure slide is designed for the simultaneous opening or closing of several dispensing openings.
  • the concrete feed device comprises a plurality of independent concrete conveying devices distributed over the threshold length, preferably in the form of screw conveyors.
  • This measure enables a precise distribution of the concrete over the entire length of the threshold, which is elongated in the direction of the threshold.
  • Appropriate control of the individual conveying devices can also take into account the fact that, in the case of a lateral gradient, the concrete flows to the lower side until it solidifies, particularly during the vibrating process. In order to compensate for this, less concrete is fed into the lower-lying area from the outset by appropriately controlling the conveyor equipment.
  • the concrete storage container have an uneven container bottom with the individual conveying devices, in particular screw conveyors, each with associated reductions.

  • the device according to the invention can further be characterized by at least one pressure plate arrangement which is attached to the frame in a height-adjustable manner between a lower end position and an upper end position, the pressure plate arrangement in the lower end position resting on the surface of a concrete layer previously poured into the threshold space and in which upper end position is lifted up out of the threshold gap.
  • the concrete surface should either be inclined to one side, in particular in curves, or be designed like a gable roof.
  • the printing plate arrangement have two printing plate sections which are angularly adjustable relative to one another and / or relative to the frame. This pressure plate arrangement also eliminates other surface irregularities such as Stair-shaped formation due to the transverse sheets used or holes formed in the concrete from the extracted vibrating bottles.

  • the two edge beams 14 are passable after curing. They can easily be manufactured so precisely that they can serve as the basis for the adjustment of the track yoke 16 (pre-assembled unit from the two rails 18 and the sleepers 20). Furthermore, they limit a threshold gap 22 above the concrete slab 12 in the manner of a side formwork. This is after the adjustment of the Gleisjochs 16 poured with concrete to permanently connect the Gleisjoch to the concrete slab 12 and thus to the track substructure.

  • the operation of the device 34 described is as follows: After a track yoke (control length 25 m / often preassembled to a section up to 150 m long) has been placed on the base plate previously cast and hardened together with edge beams 14 in a manner not shown, the device 34 is brought from its last place of use. For this purpose, the bearing beams 46 are each moved into a lower end position 46 'indicated on the right in FIG. 2, in which the track wheels 48 rest on the rails 18 and, accordingly, the frame 36 is lifted off the edge beams 14.

Then the entire device 34 is moved so far into the area of the new track yoke that the foremost track undercarriage passes over this joint and is arranged above the rear rail end. In this position, the frame 34 is only supported by the other track undercarriages, so that the front track undercarriage accordingly has a clear distance from the rails of the new track yoke.
