    Description TECHNICAL FIELD The invention relates to a covering for rail tracks, in particular rail tracks in tunnels.
    PRIOR ART Track coverings for railway track tracks for persons, in particular railway personnel and track workers, provide a level footpath at the level of the rails and thus easier and fast crossing of the tracks with a minimum of stumbling points. They serve in particular a safe escape route.
    Such covers usually consist of metal grates, which are arranged between and next to the tracks.
    For example, DE 10152 601 discloses a covering of areas adjacent to and between tracks serving as a track crossing. The cover has a plurality of arranged under the rails base plates, which are fastened by L-shaped brackets to the rail feet by clamping. Cover plates and grids are fixed on the base plates.
    In tunnels are for roofing for Schienengeleise and especially for escape routes due to increased difficulties in case of fire special regulations.
    DE 20 2009 014 226 U discloses a railroad crossing over Schienengeleise, inter alia in tunnels. The transition consists of modules of several arranged between and next to the tracks grates, which lie on several square support elements. The support elements are each arranged in height adjustable on a mounting element with a clamping mechanism, which clampingly surrounds the rail foot. The height adjustment of the support elements runs at a right angle to the mounting element. This transition with the modularly arranged grates and adjustable mounting elements is particularly easy and quick to assemble and disassemble.
    Description of the Invention It is the object of the present invention to provide a track covering for providing a passenger crossing and escape route via tracks which provides safe traversal of the tracks with minimal stumbling points, particularly for tunnel use and for tracks on which high speed trains run.
    This object is achieved by a track-covering system according to claim 1. There are also disclosed embodiments of the invention according to the dependent claims of claim 1.
    The inventive track covering has a base plate which is arranged under the rails, and walking surfaces which extend between and adjacent to the rails of the track. The fixation and attachment of the walking surfaces on the base plate is realized by means of bow-shaped fasteners and angle iron. The bow-shaped fasteners connect the base plate with a rail foot on both sides of each rail. At each bow-shaped attachment a first angle iron is fixed in each case, to which in turn a second angle iron is joined, wherein the two angle iron form essentially a two-stage stair structure. A walk-in area or walking area is attached to the second, angle iron, which is higher in the stair structure. The two angle irons are joined at a predetermined angle α, and the walking surfaces are inclined at an angle of 90 ° -a with respect to the base plate.
    The two angle iron between the walking surface and the bow-shaped attachment of the base plate to the rail essentially form a two-step stair structure, wherein the angle between the first, lower angle iron, and the second, higher angle iron according to a desired inclination of the walking surface with respect the base plate is adjusted. This angle can be a right angle, but can also deviate from a right angle. An inclination of the walking surface with respect to the base plate is necessary when the base plate and thus the rails are not horizontal but are inclined, such as in a curve.
    The inventive mounting structure for the walking surfaces with the two stepwise arranged angle iron allows a desired and in particular precise alignment of the walking surfaces with respect to the base plate and the horizontal.
    By the angular orientation of the walking surfaces is very precisely adapted to the inclinations of the respective rails, the height of possible stumbling on the inventive track covering is reduced to a minimum. This optimizes the safety of a rail crossing and an escape route, especially in a tunnel. The inventive track covering can be realized for different rails. For example, the rail tracks are inclined in a curve, wherein in case of a double track of the tracks, the inclination of the tracks of the inner curve and the inclination of the tracks of the outer curve are different. In addition, typically the two rail tracks of a track are slightly inclined to each other. These differences in inclination can be taken into account in the inventive track covering.
    In one embodiment of the invention, the base plate made of metal, wherein the bow-shaped attachment to the rail foot of an electrically insulating material, such as plastic, is made. This choice of material ensures electrical insulation of the two rail tracks.
    In a fire in the tunnel, this attachment would melt and be destroyed by the heat. The angle iron mounted thereon together with the walking surfaces fastened to it would then lower towards the rail foot. This would be the lowest lying parts of the angle iron, that is, the perpendicular leg of the lower angle iron to lie on the rail foot. As the walking surfaces lower, a stumbling point would form between the walking surfaces and the rails. The height of the trip is limited, however, because the first, deeper angle iron comes to rest on the rail foot and so still at a certain height above the base plate.
    In a further embodiment of the invention, the walking surfaces are made of aluminum, for example as a rust. This minimizes the risk of disturbing the locomotive control by not causing any magnetic forces through the aluminum walking surfaces. In addition, the walking surfaces are considered refractory due to the relatively high melting temperature. Due to the poorly conductive property of the aluminum, the electrical insulation of the two rail tracks would be guaranteed in case of fire and contact of the rails by the angle iron.
    In a further embodiment of the invention, the walking surfaces between the rails are made as a plate made of concrete, wherein the walking surfaces are made next to the tracks of aluminum. Concrete is suitable as a non-magnetic, non-conductive, and refractory material for the same reasons for the inventive covering. The concrete walkway between the rails reduces the risk of disturbances in the locomotive control to a minimum. In a further embodiment, all walking surfaces are made of concrete, in a further embodiment of the invention, the bow-shaped attachment to the rail foot is anchored by a threaded rod to the base plate. The threaded rod is anchored to the base plate with a locking screw with a nut, a spring washer and a split pin.
    In a further embodiment, the first angle iron lying deeper on the attachment extends parallel to the rail locally parallel to the rails around the region of the bow-shaped attachment. In a further embodiment, the second angle iron lying higher on the first angle iron extends parallel to the rail over the entire length of the walking surfaces of the track covering.
    In a further embodiment, the walking surface is fixed in each case at the second, higher-lying angle iron by means of a plate or an angle iron and a screw with nut by clamping.
    In a further embodiment of the invention, each screw for clamping attachment of the walking surface on the second angle iron and each screw on the first angle iron on a sapwood. In addition, the walking surface in each case at the points above said screws with split pin on each recess. The recesses allow an efficient visual and metrological condition check from above. Such tests are necessary for safety reasons.
    The inventive track covering is suitable for use in tunnels by an escape route with minimized stumbling is granted in case of fire. In particular, it is suitable for tracks driven by high-speed trains, as their attachment to the rails can withstand the very frequent and very high suction and compression forces of up to 500 kg per square meter caused by high-speed trains traveling at 200 km / h. h caused. In addition, it is particularly suitable for tunnels by remaining functional for a long time of up to 30 years and rarely having to carry out repair work for which the tunnel would otherwise have to be blocked.
    The inventive track covering has the further advantage of being used and installed on tracks with different types of sleep, such as sleepers made of wood, metal or concrete.
    In the following description, the invention is explained in more detail with reference to schematic drawings and embodiments illustrated therein.
    Brief Description of the Figures [0023]
    1 shows a plan view of a track section with an installed track covering according to the invention. In one part of the figure, the track cover with remote walking surface is shown to reveal the mounting structure.
    FIG. 2 shows a section of the track covering according to II-II in FIG. 1.
    FIG. 3 shows a cross section of the track covering according to III-III from FIG. 1.
    In the figures, the same reference numerals are used for the same elements. First explanations apply to all characters, unless explicitly stated otherwise.
    EMBODIMENTS OF THE INVENTION Fig. 1 discloses the track covering according to the invention in a view as a whole. The tracks 1 on thresholds 1a with rails 2 and rail feet 3 are covered by the track covering 4 over a length L parallel to the rails 2, which can be used in this area as a passenger crossing and in particular as an escape route. The track covering 4 has as a base on a base plate 5, which is arranged under the rails 2 and rail feet 3 and extends over the entire area in length L and width of the track covering. Walkable walking surfaces 6a and 6b are arranged between the rails 2 or on the outside thereof. On the sides of the walking surfaces 6a, b along the rails 2, a part 7a of the walking surfaces 6a, b are recessed at regular intervals. Through the recesses 7a screws 9 are visible with a split pin for fixing the walking surfaces. Further recesses 7b are each spaced from the recesses 7a through which screws 12 are visible. In the part of Fig. 1, in which the track covering without walking surface 6b is shown and in Fig. 2 angle iron 8 and 10 and mounting plates 11 are shown, by means of which the walking surfaces 6a, b are attached. First angle iron 8 are arranged near the rail feet 3 and extend only over a limited area along the rails 2. The screws 9 are used to attach the first angle iron 8 to the base plate 5. Second angle iron 10, which are connected to the first angle iron 8 , extend over the entire length L of the track covering 4. The mounting plates 11 are fastened by means of screws 12 to the second angle iron 10. Both the screws 9 to the first angle iron 8 and the screws 12 to the second angle iron 10 are executed with a safety pin 17 and 21, respectively.
    Fig. 3 shows the attachment of the walking surfaces 6a, b at the rail feet 3 in detail. The attachments of the two walking surfaces 6a and 6b on both sides of the rail 2 shown are basically identical in that they have the same elements and are based on the same principle. They differ in the angular orientation of the angle iron 8 and 10 to each other. In the cross-sectional view, a metal base plate 5, for example made of steel, is arranged under the rail feet 3, wherein the base plate and the rail feet are electrically insulated by a layer 13. A bow-shaped attachment 14, which sits on the one hand on the base plate 5 and on the other hand on the rail foot 3 is fixed by means of a screw 9 with threaded rod 9 'on the base plate 5. The bow-shaped attachment 14 can be realized for example by an attachment of the type Aeki the Swiss Federal Railways (SBB) or other threaded bolts. In particular, the attachment 14 is made of an electrically insulating material such as plastic, so that the rail tracks 2 of the track 1 are insulated from each other. A first, angle iron 8, a 90 ° angle bracket is disposed between the bow-shaped attachment 14 and the screw head 16 of the screw 9. The one leg 8 'of the angle iron 8 extends substantially perpendicular to the base plate 5 to the rail foot 3 down, said leg 8' is vertically above the rail foot 3. The second leg 8 »of the angle iron 8 runs parallel to the base plate. The positioning of the vertical leg 8 'ensures that in case of fire and consequent destruction of the bow-shaped attachment 14 by melting the angle iron 8 lowers on the rail foot 3 and comes to rest there. As a result, the resulting reduction in the walking area 6a, b is slight and the rail 2 would represent only a minimum stumbling threshold relative to the walking area 6a, b.
    Between the angle iron 8 and the head 16 of the screw 9, a spring ring 15 is arranged. In addition, the screw 9 has a split pin 17. Thanks to the recess 7a, this split pin 17 can be easily seen by inspectors and tested for its function. The threaded rod 9 'and screw 9 are fastened by means of a nut 18 to the base plate. At the first angle iron 8, the second angle iron 10 is fixed, for example by welding. This second angle iron 10, again a 90 ° angle support, is in the embodiment shown at an angle a the leg 8 "of the first angle iron 8. The two angle iron 8 and 10 thereby form a two-stage stair structure The figure to the right of the rail 2) is fastened to the second angle iron 10, which is higher in comparison to the first angle iron 8. By the angle a, in the embodiment shown for the walking surface 6b is greater than 90 °, as it by means of the vertical lines to the dashed lines If the leg 8 'of the angle iron 8 is indicated, an inclination of the walking surface 6b relative to the base plate 5 results at an angle of 90 ° -a (the drawn angle 90 ° -a is the angle between the base plate 5 and the parallel to the walking surface 6b. This lies obliquely to the horizontal H, the inclination of the walking surface 6b compensating for the inclination of the base plate, the angle may also be 90 ° or less than 90 ° n, depending on the inclination of the rails 2 and the surrounding terrain.
    This is shown in FIG. 3 using the example of the walking surface 6a (in the figure to the left of the rail 2). The walking surface 6a is inclined differently with respect to the base plate 5 in comparison to the walking surface 6b. This is determined by the choice of the angle α between the first and second angle iron 8 and 10 to the right of the rail 2. The angle ß is there about 90 °.
    The walking surface 6b is clamped in the embodiment shown by means of a plate 11 and a screw connection. In the embodiment shown, this connection is realized by means of a screw 22 with nut 23. In this case, the head of the screw 22 is located in the recess 7b, so that it does not protrude from the walking surface 6b, but on the other hand again clearly visible and can be tested by staff on their function. The screw 22 has, like the screw 9, a split pin 21.
    As an alternative, the walking surface 6 b can also be attached directly to the upper leg of the angle iron 10.
    The walking surfaces 6a, b are made in the example shown in FIGS. 1 and 3 from a grid of non-magnetic material, preferably aluminum. This lowers the risk of disturbing the control of the locomotives. In addition, aluminum is largely resistant to fire.
    In an alternative embodiment, the walking surface 6b in the middle between the rails over which the locomotive travels is made of a concrete slab. This further reduces the risk of malfunction. The outer two walking surfaces 6a may also be made of concrete slabs or aluminum slats. In a further alternative embodiment, all walking surfaces 6a and 6b are made of concrete.
