Description

The invention relates to an identical roof covering for tracks where the between the two rails of a track with passable panels arranged in pairs is filled or bridged, which with at least one Only engage the edge strip in the tab compartments of the rails are supported on the rails and the distance between the Bridge the cantilever rails, whereby the two plates of the Plate pairs are joined together in an articulated manner.

Rail-like coverings for tracks are provided, to enable road vehicles to drive on track areas. A particularly important area of application are level railroad crossings, i.e. crossing points of Street lanes with railway lines. It comes to storage the components that form the roadway in the track area of great importance because of the vehicles passing the transition, especially from the rail vehicles, considerable static and dynamic loads on traffic routes be exercised. The elastic properties of the Track, which is largely determined by the track bed are possible in the area of a rail-like transition not or only a little of the properties in question the track sections following such a transition be made to deviate. This seems feasible if the properties of the track bedding not by directly on the Components of the roadway superimposed on bedding elements have been changed become. One is therefore in the same track coverings come to designs in which the between the space lying on both rails of a track is bridged with plates which engage in the tab chambers of the rails and are supported only on the rails and the distance between bridge the cantilevers. There are designs, each with a single plate with its opposite Edges supported on the two rails of a track is, between the edges of such a plate and elastic profiles are arranged in the link chambers of the rails are. The insertion of such plates presents certain difficulties and requires experienced workers, and it is in the Usually required, at least on one edge of these plates for storing the same in the tab chamber of the rail two to use angular elastic profiles, the one this angle profiles on the rail foot and the other under the The rail head is to be placed. A way to look at a par Covering for track slabs, which the the between the to bridge the space between the two rails of a track and should only be supported on the rails easier way to insert between the rails is to use plate pairs, the two of which are plates are joined together like a joint, with the joint axis in Longitudinal axis of the track runs. With a known track-like Covering of this type (DE-23 50 759-A2) can be Unfold the plate pair and insert this plate pair relatively easy between the two rails of a track be carried out, but it will be by the one provided Formation of the joint-like connection in the form of a between the two plates of the plate pair inserted joint rod, on which the plates just rest, when they occur greater loads on the pair of plates from the plates strong Lateral forces trying to push the rails apart exercised on the rails, which is undoubtedly disadvantageous; there is also the danger that the stability limit will be overcome and fold the panels down until the Joint zone on the sleepers of the track comes to rest.

It is an object of the present invention to to create rail-like covering of the type mentioned at the beginning, in which the disadvantages of known training are avoided and adverse influences of static and dynamic nature on the Track and its bedding are largely switched off, and also installing and removing the between the two rails of a track to be provided in a simple manner can be accomplished.

The monoplanet covering according to the invention at the beginning mentioned type is characterized in that the plates each Plate pair at their mutually facing edges are supported and with each plate along the other plate facing edge alternating meandering successive support sections and support sections are provided are, with the support sections through from the top of the plate outgoing and up to the other plate facing edge reaching depressions are formed and under the support sections starting from the underside of the plate, upwards directed depressions are formed, which are complementary to the depressions of the support sections are formed, and the support sections one plate on the support sections of the other Plate and the support sections of the other plate on the Support sections of one plate rest. Through this training can build on the above objective be easily met well. The articulated to be put together Zones of the plates of each plate pair can be at unfolded standing plates are simply put together, after which the plates smoothly leveling the pair of plates can be inserted between the rails, and it will be the Panels even when exposed to large loads, such as at the Heavy trucks roll over them, not being pushed apart.

A preferred embodiment, which is characterized is that on those surfaces where the plates have a Plate pairs lie together, protrusions and complementary to the protrusions formed recesses into which the protrusions snap in, provided for mutual locking of the plates are the advantage that the cohesion of the plates one Even then, plate pairs are backed up over very long periods of time is when unfavorable vibrations hit the panels act.

In the sense of one it is as simple as possible and with little Exertable effort of inserting the plates between the rails and in the sense of the possibility of a easy removal of the panels is an advantage if you provide that the wings provided in the support sections of the the other plate of the plate pair facing edge starting first steeply rising from the underside of the plate and then are becoming flatter. It is also cheap and also to ensure a stable cohesion over long periods the plates in their installed condition are an advantage, if it is provided that the provided in the support sections Wings have a convex shape, which in the leveled Position of the plates of the respective plate pair mutual movement of these plates in the direction of the plate plane inhibits. Such crowning can be done on a plate one facing the other plate of the plate pair Edge outgoing surface section that extends from the bottom removing the plate and a subsequent one Surface section; approaching the bottom of the plate runs, be formed. If you want one of those Training of the plates additionally provide a latching it is advantageous if one trains them in such a way that the Front edges of the support sections downward projections and on the wings of the support portions to these protrusions complementary recesses are provided.

Particularly favorable for the leveling process when installing the panels and for achieving one if possible stable position of the two plates of a plate pair to each other in the installed state is an embodiment, which thereby is characterized that the domed wings are shaped according to a toothing, which up to leveled position of the plates of the respective plate pair a sliding movement or rolling movement of the facing one another Wings and supporting surfaces on top of each other and in the leveled position of these plates against movement of these Locks plates to each other.

There is also one for joining the plates together of a pair of plates and for the subsequent relative movement of these two plates in the process of installing the plates cheap Geometry, if one provides that the plates face each other facing edges starting from the underside of the plate are rounded at the top, the radius of curvature equal to or less than the distance between them Edges and the rail-side edges of the plates. Further it is for a simple assembly of the panels a pair of plates advantageous if you provide that the approximately two plates of a pair of plates on the underside of the plate apart along a straight line. If you want to achieve the highest possible load-bearing capacity of the plate pair, it is favorable if one provides that the two plates one Plate pair interlocking on the underside of the plate lie together.

As material for the slab-like covering panels are in particular concrete, such as cement concrete or polymer concrete, or Similar composites from lumpy aggregate and binder intended. It is usually cheap here in the Arrange slabs of reinforcement. A preferred one Embodiment is characterized in that the plates Concrete or a concrete-like composite material particulate aggregate and binder are formed and a Have reinforcement, which is over the slab surface extends and into the support sections and into the support sections and engages in the at least one sidebar.

The invention also relates to a rectangular drive-over plate for a rail-like trained as set out above Covering for tracks. This plate is characterized by that the plate on the opposite of the said border Edge side in meandering succession of supporting sections and has support portions, wherein the support portions by by starting from the top of the plate and reaching to the edge depressions are formed above and under the support sections depressions starting from the underside of the plate are formed, which are complementary to the depressions of the support sections are shaped. It is preferably provided that the plate made of concrete or a concrete-like composite material is formed from particulate aggregate and binder. It is also advantageous if one in the plate over the entire plate surface extending into the support sections and in the support sections and in the at least one edge strip sufficient reinforcement is provided.

In the embodiment shown in Figures 1 to 3 a rail-like covering designed according to the invention for tracks the one between the two rails 2, 3 is one Track 1 lying space 4 with plates 5, 6 arranged in pairs filled or bridged. These plates 5, 6 have edge strips 7 which engage in the tab chambers 8 of the rails 2, 3, and there are between the edge strips 7 and the rails 2, 3 elastic profiles 9 with an approximately C-shaped cross section inserted. It is in this way the plates 5, 6 with their edge strips 7 on the rail foot 10 and laterally against the rail web 11 supported and upwards by engagement under the Rail head 12 held. The plates 5, 6 bridge the Distance 13 between the rails 2, 3 self-supporting. It's on each of the plates 5, 6 several edge strips 7 are provided, which are spaced from each other by the for the rails 2, 3 provided fasteners 14 accessible. But you can also choose the plate dimensions and other Panel mounting arrangement only one on each panel Provide edge bar 7.

At their mutually facing edges 15, 16 are the Plates 5, 6 of each pair of plates supported on each other, so that each pair of plates has a distance 13 between the rails 2, 3 self-supporting bridging assembled body forms. For this purpose, each plate 5 or 6 along the other Plate 6 or 5 facing edge alternating meandering successive support sections 17 and support sections 18 provided, the support portions 17 through by the Plate top 19 outgoing depressions 20 are formed, which extend to the edge facing the other plate; are underneath the support sections 18 from the underside of the plate 21 outgoing, upward, depressions 22 formed, and there are the support portions of the plate 5 on the Support sections of the plate 6 and the support sections of the plate 6 on the support sections of the plate 5; the depressions 20 are complementary to the depressions 22, so that the formed on the support sections 18 by the depressions 22 Support surfaces 24 substantially full on the depressions 20 wings formed on the support sections 17 23 rest. For the aforementioned formation of the plates can also on the representation of such a plate in Fig.4 be pointed out.

To the plates 5, 6 in pairs between the rails 2, 3 one You can insert the track first, as shown in Fig. 5 is shown, arrange in the unfolded position, and thereby with their meandering edges 15, 16 inserted into each other, where one also the elastic profiles 9, which one Have C-shaped cross section, between the edge strips 7 of the Arrange plates 5, 6 and the rails 2, 3. After that, the Plates 5, 6 pivoted down or folded, as by the Arrow 25 is indicated until it reaches the one shown in FIGS. 1 to 3 assume the leveled position shown, in which the plates 5, 6 of each pair of plates, the space 4 between the rails 2, 3 cantilever bridge.

The wings 23 provided in the support sections 17 have a cambered shape, and there is such a cambered Shape also in those provided on the support sections 18 Support surfaces 24 in front, and it is by this convex shape of the surfaces mentioned a form cohesion of the plates 5, 6th created, which in the leveled position of the plates 5, 6 a mutual movement of these plates in the direction of Plate level (arrows 26) inhibits. Furthermore, are on the support surfaces 24 projections 27 and depressions 28 on the wings 23, which are complementary to the projections 27, intended; in the leveled position of the plates, the Projections 27 in the recesses 28, so that a mutual locking of the plates 5, 6 results.

Can between the wings 23 and the support surfaces 24 if desired an elastic and / or shock-braking effect Inlay or coating can be provided.

The wings 23 provided on the support sections extend from the edge 15 or 16 of the plate 5 or 6 in question, starting from the underside of the plate 21, first steep rising and then flattening, what kind of joining the plates to the plate pairs is advantageous. Geometric seen it is favorable if such a domed shape Wings are shaped according to a toothing, which to the leveled position of the plates 5, 6 of the respective Plate pair a sliding movement or rolling movement of the mutually facing wings and supporting surfaces on top of each other enables, and in the leveled position (Fig. 1 to 3) this Locks plates against movement to each other. This geometrically a surface shape corresponding to a toothing can be up to the Plate top 19 is enough.

The projections 27 can, as shown in FIGS. 1 to 4, provided on the end edges 29 of the support sections 18 be what can bring advantages when joining the panels together, but it is also possible to have such projections 27 elsewhere, e.g. slightly moved away from the edge of the support surfaces.

In the variant shown in Figure 6 are the wings 23 and the support surfaces 24 are largely flat; to mutual locking of the plates 5, 6 are also in this Case depressions 28, in which projections 27 engage, intended.

Both in the embodiment shown in Figures 1 to 3 as well as in the variant shown in Figure 6 two plates 5, 6 of a pair of plates on the underside of the plate 21 meandering interlocking, so that the mutually facing edges of the plates 5, 6 on the underside of the plate follow a meandering line 34. It This results in a very close cohesion of plates 5, 6 forming a pair of plates with one another

But you can also get in touch with each other or engaged portions of the plates of a Select the pair of plates so that the mutually facing edges 15, 16 of the plates 5, 6 on the plate underside 21 along one Straight lines 30 lie against each other, whereby both the manufacture of the Plates as well as the process of the assembly process simplified can be; such training lies with the 7 to 12 embodiments shown. Lots Details of these embodiments are analogous to the embodiments 1 to 6, and it can therefore here in connection with the above discussions 1 to 6 are pointed out. It is in the embodiment 7 to 10 a cambered shape of the wings 23 provided, while the variant according to FIG has substantially flat design of these wings 23. In both cases are projections 27 which are in depressions 28 engage, arranged on the end edges of the support sections. However, as already mentioned above, such projections 27 can be used also place elsewhere in the area of the support surfaces.

7 to 12 are in the embodiments the plates 5, 6 on the mutually facing edges 15, 16 of the plate underside 21 starting to be rounded upwards shaped, the radius of curvature of this rounding the same size how or less than the distance 31 between the edges 15, 16 and the rail-side edges 32 of the plates 5, 6. Also this measure is for an uninhibited process of the Inserting process of the plates is an advantage.

It is usually cheap to have reinforcement in the slabs to arrange. According to a preferred embodiment provided that the reinforcement 33 over the entire area of plates 5, 6 is sufficient, as shown in Fig.4 is indicated by dashed lines, both in the support sections 17 and in the support sections 18 and in the edge strips 7 intervenes.

Furthermore, it is possible to plate 5, 6 with frame 35 provided, e.g. is indicated by dashed lines in FIG.

From Figures 7 to 9 it can also be seen that the purpose Sound absorption in the plates 5, 6 cavity resonators 36 with the sound openings 37 opening the top of the plates could be.
