    The invention relates to a transition plate and a rubber molded body for such a transition plate and a rail level crossing with such transition plates according to the preamble of each of the claims 1, 3 and 9.
    In level crossings, it is known to arrange transition plates in the space between the rails of a track and possibly outside adjacent to the rails or alternatively to install in these areas an asphalt or concrete layer. As a result, the level of the intersecting traffic route can largely be maintained even in the transition area. Transition areas that are permanently connected to the subsurface have the disadvantage that they make it difficult to carry out inspection and maintenance work on the tracks or have to be removed for carrying out such work and subsequently recreated again. With such transitions, maintenance takes a correspondingly long time and causes high costs.
    Conventionally, wood, concrete or rubber plates are used for the production of rail level crossings usually.
    For level crossings with concrete slabs of the installation and removal of concrete slabs is usually associated with considerable costs. In particular in the case of so-called track slabs, damage to the tracks and to the ballast bed often occurs in the installation area. Concrete, in particular reinforced concrete, is well suited for driving on vehicles because of its hardness or dimensional stability, its static load capacity and its adhesive properties. On the other hand, vibration and weathering can easily cause damage to concrete slabs.
    For rubber panels, the risk of damage from weather and vibration due to the elastic deformability of this material is lower. Other advantages of rubber are its electrically insulating and mechanically vibration damping properties.
    When driving on plates made of solid rubber, however, the forces acting on these plates large forces can cause deformation and severe wear of these plates. In particular, the loads are not distributed uniformly on the bases of the thresholds when driving on such plates and transferred to the ballast bed. As a result, damage can also occur in these areas.
    An object of the present invention is therefore to provide a transition plate for rail level crossings, which combines the good properties of concrete and rubber and minimizes their disadvantages.
    This object is achieved by a transition plate and by a rubber molded body for such a transition plate according to the features of claims 1 and 3 and by a rail level crossing according to the features of claim 9.
    The transition plate comprises an approximately cuboid reinforced concrete plate, which is embedded in an elastically deformable trough-shaped rubber molded body. The edge of the rubber molded body surrounding the reinforced concrete slab is flush with the top of the reinforced concrete slab. The rubber molded body is clamped between two rails of a track, wherein the adjacent to the rails longitudinal edges of the rubber molded body are shoulder-like designed with a lower height so that they anstos-sen below the rail heads to the rail webs and ruts free. The level of the upper surface of the reinforced concrete slab and the level of the adjacent upper surface of the rubber molded body preferably correspond within permissible tolerance limits of, for example, one centimeter to that of the upper side of the rails. Between the rails of the rubber molded body is preferably on a threshold support plate, which is preferably made of rubber-elastic material and is supported on at least two thresholds of the track.
    In a railroad crossing, two or more transition plates can be assembled in the direction of the rails. For this purpose, the rubber moldings comprise coupling elements along their transverse edges. Preferably, these coupling elements are formed as grooves and springs or generally as female and male coupling elements, which are in mating engagement with each other after assembly. Depending on the embodiment, the transverse edges of a rubber molded body may comprise only male or female male or female coupling elements. In a particularly advantageous embodiment, the rubber moldings in the region of the transverse edges include recessed metal profiles, which stabilize the shape of the coupling elements and can be screwed together. The inventive transition plates can be mounted with little effort at a railroad crossing and just as easily removed if necessary. For installation, threshold support plates whose thickness is matched to the dimensions of the rails, the sleepers and the rubber molded body are first placed on the sleepers. Thereafter, the rubber moldings are inserted between the rails and connected to each other. Preferably, the transverse edges of the rubber moldings in the middle region comprise a weak point, for example a V-shaped notch formed between two reinforcing metal profiles on the front side, so that the rubber moldings can easily be kinked or elastically deformed for insertion into the space between the rails. Subsequently, the reinforced concrete slabs are inserted into the receptacles of the rubber moldings. Preferably, the reinforced concrete slabs comprise one or more threaded sleeves, in which hooks or eyes can be screwed back releasably for assembly purposes. The reinforced concrete slabs are held in the rubber moldings solely because of their great weight. The inner walls of the rubber moldings and the side walls of the reinforced concrete slabs are slightly conical. Due to the weight of the reinforced concrete slab and the additional weight of vehicles passing through the railroad crossing, the reinforced concrete slab and the rubber molded body are additionally wedged together in a force-locking manner. Optionally, in addition, a positive connection between the rubber molded body and the reinforced concrete slab are created, for example, by the front side of the reinforced concrete slab further threaded sleeves are formed, which can be used for tightening the rubber molded body in the region of their transverse edges with the reinforcing metal profiles.
    The inventive transition plates transfer the forces exerted by vehicles when driving on the level crossing forces uniformly on the threshold support plates and from there to the support areas of the thresholds and the ballast bed. The elastic damping of the transition plates protects rail and sleeper areas. The transition panels are weather-resistant, sound and vibration insulating, current insulating and robust and prevent deflections and deformations of the superstructure due to road traffic.
    Based on some figures, the invention will be described in more detail below. Show

    Fig. 1 shows a section of a railroad level crossing with two transition plates 1, which are clamped between two rails 3 of a track and connected to each other. The rails 3 and the transition plates 1 are supported on sleepers 5 in a ballast bed (not shown), the connecting areas of adjacent transition plates 1 preferably being arranged above the sleepers 5. Between the rails 3, one or more threshold support plates 7 rest on the sleepers 5. The thickness or thickness of these threshold support plates 7 is matched to the type or dimensions of the rails 3, the sleepers 5 and the transition plates 1, that the transition plates 1 rest on these threshold support plates 7. The weight of the transition plates 1 and the traffic crossing the railroad crossing can thus be supported evenly on the sleepers 5.
    Each transition plate 1 comprises a trough-shaped rubber molded body 9 (FIGS. 4 and 5) and a reinforced concrete plate 11 mounted in this rubber molded body 9 (FIG. 3). The rubber molded body 9 comprises a trough bottom 9a with one or more recesses 10 and two opposing pairs of side walls 9b, 9c whose upper and lower edges are in pairs parallel, and which together form a frame. Through the recesses 10, the drainage of leachate is possible. The frame limits an upwardly open and upwardly slightly conically widening receiving area for a reinforced concrete slab 11. This receiving area and the reinforced concrete slab 11 are at least approximately cuboid. It comprises a cover surface 11a with slightly rounded corners, two pairs of side surfaces 11b, 11c with pairwise parallel upper and lower edges and a bottom surface 11d. The jacket with the side surfaces 11b, 11c is slightly conical in accordance with the shape of the receiving area.
    From the top surface 11a forth two embedded in the reinforced concrete slab 11 threaded sleeves 13 are accessible, which can be used for screwing in again releasable hooks or eyes 15 (Fig. 10). These can be used during assembly and disassembly for raising and lowering the reinforced concrete slab 11. Preferably, the threaded sleeves 13 are formed corrosion resistant. The reinforced concrete plate 11 completely penetrating threaded sleeves 13 allow the flow of water. Alternatively, the inlet openings of the threaded sleeves 13 can be sealed, for example by plugging or otherwise, so that no water can penetrate. In a railroad crossing, two or more transfer plates 1 can be interconnected. For this purpose, the Gum include

    miform body 9 on the side walls 9c, which are aligned transversely to the rails 3, coupling elements. Preferably, these coupling elements comprise springs 17 and grooves 19, which are formed along the side walls 9c of the rubber molded body 9, wherein male and female coupling elements engage positively in one another during the assembly of adjacent rubber molded body 9 or engage behind each other in a form-fitting manner. Fig. 6 shows schematically a cross section in the region of a junction of two transition plates 1,1 '. The left transition plate 1 comprises a molded rubber part 9 with male coupling elements. In these projecting in the lower region of the side wall 9c a paragraph on the top of a groove 19 and a spring 17 are formed. The right transition plate 1 comprises a molded rubber part 9 with female coupling elements. In these projecting in the upper region of the side wall 9c a paragraph, on the underside of a groove 19 'and a spring 17' are formed. When joining the two adjacent transition plates 1, the springs 17, 17 'engage in a form-fitting manner in the grooves 19', 19 of the respective other transition plate 1, and the springs 17, 17 'engage behind one another. In principle, both side walls 9c of a rubber molded body 9 may comprise identical or different coupling elements. The coupling elements may extend over the entire length of the side walls 9c or be formed only in sections on these side walls 9c. To reinforce the springs 17 and grooves 19 9c metal profiles 21, 23 are embedded in the rubber molded body 9 in the region of the side walls, the shape of which is adapted to those of the coupling elements. Preferably, two such metal profiles 21 and 23 are arranged distributed in the longitudinal direction at each side wall 9c. Between these reinforcing elements, the side walls 9 c have weak points for buckling or bending of the rubber molded body 9 when it is to be inserted into the space between two rails 3. By V-shaped notches 25 (Fig. 10) in the middle of the side walls 9c, the bending or buckling of the rubber molded body 9 can be further facilitated. In FIGS. 7 and 8, two complementary metal profiles 21, 23 are shown. The one metal profile 21 comprises two nuts 27, the other metal profile 23 two with these nuts 27 in the assembled state of the rubber molded body 9, 9 'aligned through holes 29 for screws (not shown). In this way, composite rubber moldings 9, 9 'can be connected to each other by screws. The screws can be inserted through corresponding openings 31 '(Figure 6) at the top of the side wall 9c'. Fig. 9 shows a cross section of a level crossing in the region of one of the rails 3. The side wall 9b of the rubber molded body 9 comprises an abutment portion 33 adapted to the shape of the rail body between the rail head 3a and the rail foot 3b. One over the entire length the rubber molded body 9 extending recess 35 adjacent to the rail head 3a serves as a rut. Fig. 10 shows an inserted into the rail space transition plate 1, in which for lifting the reinforced concrete slab 11 two eyelets 15 are screwed into the threaded sleeves 13. Shape and size of the transition plate 1 and the parts of this transition plate 1 can be set differently depending on the characteristics and dimensions of the respective tracks. The width of the reinforced concrete slab 11 and thus also the width of the receiving area in the rubber molded body 9 in the direction of the side walls 9c is greater than the width of the side walls 9b between the receiving area for the reinforced concrete slab 11 and the bearing areas 33 which can be pressed against the rails 3. Due to the slightly conical Shape of the reinforcing steel plate and the receiving area in the rubber molded body 9 reinforced by the load of the reinforced concrete slab 11, the frictional connections between the rubber molded body 9 and the rails and between the rubber molded body 9 and the reinforced concrete slab 11. The reinforced concrete slab 11 may, for example, a weight of about 150 kg to about 300 kg, which is preferably in the order of about 200 kg to about 250 kg. Different rubber spacers 9 can be made with adapted to these rail distances lengths of the side walls 9c for different track distances. Alternatively, molded rubber bodies 9 can be manufactured with greater lengths by cutting rubber moldings 9 centrally with shorter lengths of the side walls 9c, ie along a line transverse to the side walls 9c. The dividing line thus passes through the two notches 25. Subsequently, latch-type connecting elements of suitable length are inserted between the separating points at the adjacent portions of the side walls 9c and connected to the adjacent side wall portions (not shown). Material and shape of the connecting elements are preferably selected to be the same or similar to the adjacent side wall sections. claims
