Definitions

  • the invention relates to a track body with the features of the preamble of claim 1.
  • a track body of this type is known for example from the Austrian patent 382 178 or from the EU-OS 456 147.
  • the edge-side sections of the sleepers lie in recesses of a substantially U-shaped concrete body, which can be formed, for example, by a bridge structure. Sound-reducing, elastic intermediate layers are provided in the above-mentioned recesses in the concrete body, on which the edge-side sections of the sleepers rest.
  • This construction has proven itself, its disadvantage is that a large amount of formwork is required to manufacture the concrete body.
  • a superstructure for railroads has become known from German laid-open specification 38 09 466.
  • This superstructure consists of a support plate laid on the ground level or of laid support plates, preferably of a seamlessly made plate made of concrete or bituminous mix, which can be provided with an upper leaching layer made of asphalt concrete.
  • the track grating consisting of rails screwed to sleepers is glued by a casting compound based on bitumen and / or plastic.
  • asphalt mastic or mastic asphalt is filled between the sleepers into the sleeper compartments in one or more work steps to a height of approximately half to the full height of the thresholds.
  • Asphalt mastic or mastic asphalt it is a very expensive material -saving, it is also provided that beam-like precast concrete parts are inserted in the sleeper compartments, which are as long as the sleepers.
  • the gaps between the sides of the sleepers and the above-mentioned beam-like precast concrete parts are poured out with a casting compound, which also consists of asphalt mastic or mastic asphalt.
  • a track body with this structure can only be used to a limited extent in practice. Since the sleepers are only glued, longitudinal beams connected to the sleepers must be provided outside the rails to stiffen the track body. Asphalt mastic or mastic asphalt is relatively hard and has no elastic properties. At low outside temperatures, asphalt mastic or mastic asphalt becomes very hard and brittle. The thresholds drop by up to 3mm and more under operational loads. As asphalt mastic or mastic asphalt is not elastic, the connecting joint cannot follow this movement, it therefore tears open and forms a gap into which water can penetrate, which freezes at low temperatures, which leads to further damage.
  • DE-OS 38 10 700 from which a superstructure for railways is known, should be mentioned here in particular.
  • This superstructure has a foundation plate on which the track grate, consisting of sleepers and rails, is placed and spindled. Then finished concrete parts are placed in the sleeper compartments inserted, which are T-shaped in plan view and whose axis length is greater than the length of the sleepers.
  • These one-end T-shaped prefabricated concrete parts are flush with the end faces of the neighboring sleepers, and with their transverse legs they completely or at least partially cover the neighboring sleeper compartments, depending on their length. There are gaps between the sleepers and the inserted prefabricated concrete parts, which are then poured out with a compound, whereby this compound should also be placed under the sleepers.
  • this composite mass can be poured in from above, but can also be introduced in ascending fashion by lances from below.
  • the spindles that were used for the equipment and for lifting the track grate above the foundation plate are removed.
  • Precast concrete parts of this shape and size have a considerable weight, so that lifting equipment must be used for their laying, it should be borne in mind that these precast concrete parts can only be inserted into the track grille from this side.
  • the lifting gear's lifting tackle is moved around at least once when it is being pushed in, since the lifting rope or lifting gear lifting tackle cannot go underneath the rails of the installed track grate.
  • Such great effort for laying a rail track cannot be applied in practice.
  • the grouting of the joints with a compound is also an extremely complex working process, since it must be ensured that all joints are actually filled with this compound.
  • the invention aims to evolve a track body of the first type mentioned, bypassing the disadvantages and difficulties in the constructions according to the prior art, so that it can be manufactured with less effort than before, without the to impair achievable advantages through its basic structure, what is achieved according to the invention by those measures which are the content and subject of the characterizing part of claim 1.
  • a concrete foundation 2 is poured on site into the grown floor 1 along the planned track route.
  • a concrete slab 4 is placed over a mortar bed 3, which runs along the route or the concrete foundation 2 and whose width is smaller than that of the concrete foundation 2.
  • These concrete slabs 4, which follow one another along the route, are manufactured at the factory.
  • the track grate which consists of the concrete sleepers 5 and the rails 6 attached to them, is now placed and aligned on the foundation thus prepared.
  • Elastic intermediate layers 7 are fastened to the undersides of the sleepers 5, which protrude on both sides relative to the relatively narrow concrete slab 4. These can be glued or temporarily held by means of wires.
  • the track grate is not placed directly on the foundation mentioned, but via the interposition of slats 24, which are a few centimeters high and which are laid along the edges of the concrete slabs 4, so that the undersides of the sleepers 5 relative to the top of these concrete slabs 4 by are slightly distant, as illustrated in FIG. 2. Furthermore, on the end sections the sleepers 5 of the track grid laid in this way placed longitudinal slats 8, in which there are anchor bolts 9 which are screwed into threaded plates 10 at their lower end, the anchor bolts 9 being arranged on the slats 8 such that the threaded plates 10 are on the top of the concrete foundation 2 lie on.
  • these anchor screws 9 Seen in the longitudinal direction of the track grate, that is to say at right angles to the plane of the drawing, these anchor screws 9 are centered in the successive sleeper compartments. Since the side walls of the sleepers 5 are inclined, it is also possible to insert the slats mentioned in such a way that they abut the oblique side walls of the sleepers 5 at the end. This is indicated in FIG. 2 by the dashed line 25. This has the advantage that shorter anchor bolts 9 can be used compared to the first-mentioned arrangement.
  • intermediate bodies 13 are now inserted in the sequence, which have been manufactured in the factory by concrete.
  • Such an intermediate body 13 is in the Figures 4, 5 and 6 shown in different views.
  • the intermediate body 13 has a trapezoidal cross section (FIG. 5), its side cheeks 14 converging downwards. Its height H corresponds to the height of a threshold 5 or is slightly smaller than this. In its upper side there is a groove 16 open towards one end face 15, and a vertical bore 17 extends from the bottom of this groove 16. On its underside 18 here three support cams 19 are formed, which lie on the corner points of an imaginary triangle. The arrangement is such that the vertical bore 17 for receiving the anchor screw 9 lies within the imaginary triangle, preferably in the middle thereof.
  • the inclination of the lateral cheeks 14 of the intermediate body 13 is selected such that these cheeks 14 limit an upwardly converging gap 20 with the lateral sections of the threshold 5, which is indicated in FIG. 5 by a dashed line 21. This dashed line 21 indicates the side cheek of an adjacent threshold 5.
  • the twin bodies 13 thus manufactured at the factory are now inserted into the track grate (FIGS. 7 and 8). However, before these intermediate bodies 13 are inserted into the edge sections of the sleeper compartments, wedges 22 are placed on the side cheeks of the sleepers 5. These wedges are made of an elastic material, such as polyurethane. Only then is the intermediate body 13 inserted and clamped by means of the anchor screw 9, the lower end of which is screwed into the threaded plate 10, which in turn is firmly anchored in the concrete.
  • the intermediate body 13 Since the axial length 1 of the intermediate body 13 is equal to or less than the length of the end portions of the sleepers 5 projecting outwards as seen from the rails 6, these can be inserted into the track grating by means of a vertical lifting movement without them being laterally during assembly have to be moved in order to thread them into the threshold compartment from the side, so to speak.
  • the anchor screws 9 By screwing by means of the anchor screws 9, the intermediate bodies 13 are firmly anchored to the foundation 2 and thus form an immovable abutment for the track grate.
  • the track grate rests on the concrete foundation 2 manufactured on site.
  • prefabricated panels can be placed on the grown and appropriately leveled floor (level), which then form the foundation on which the track grate can be erected in the manner described.
