Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a transition plate for a rail-like path transition and a rail-like path transition with such transition plates and according to the preamble of claims 1.10.

[0002] In railroad transitions, it is known to arrange transfer plates in the space between the rails of a track and, if appropriate, adjacent to the rails, or alternatively to provide an asphalt or concrete layer in these areas. As a result, the level of the crossing traffic route can also be largely maintained in the transition area. Fixed transition areas connected to the subsurface have the disadvantage that they make the execution of control and maintenance work on the tracks more difficult or to be carried out for the execution of such work and then have to be recreated again. In the case of such transitions, maintenance work takes a correspondingly long time and entails high costs.

[0003] Conventionally, wood, concrete or rubber plates are generally used for the production of rail-like track transitions.

[0004] In the case of rail transitions with concrete slabs, the installation and removal of the concrete slabs is generally associated with considerable costs. Particularly in the case of so-called Gleistragplatten, 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 due to its hardness or shape stability, its static load-bearing capacity and its adhesion properties. On the other hand, vibrations and weathering effects can easily lead to damage to concrete slabs. In the case of rubber plates, the risk of damage due to weathering and vibrations is lower due to the elastic deformability of this material. Further advantages of rubber are its electrically insulating and mechanically vibration-damping properties.

[0005] However, in the case of driving on plates of solid rubber, the large forces acting on these plates can cause deformations and severe wear on these plates. In particular, when loading such plates, the loads are not evenly distributed to the support points of the sleepers and transferred to the ballast bed. As a result, damage can also occur in these areas.

[0006] It is therefore an object of the present invention to provide a transition plate rail-like rail transitions which combines the good properties of concrete and rubber and minimizes their disadvantages.

This object is achieved by a transition plate according to the features of patent claim 1 and by a rail-like path transition according to the features of patent claim 10.

[0008] The transition plate according to the invention comprises a parallelepiped-shaped reinforced concrete plate, which is embedded in an elastically deformable tub-like rubber-shaped body. The edge of the rubber-shaped body enclosing the reinforced concrete slab is flush with the upper side of the reinforced concrete slab. The rubber-shaped body is held clamped between two rails of a track, the longitudinal edges of the gum miform body adjoining the rails being formed shoulder-like with a lower structural height so that they strike the rail webs below the rail heads and leave bobbins free. The level of the upper side of the reinforced concrete slab and the level of the adjacent upper side of the rubber shaped body correspond preferably within permissible tolerance limits of, for example, one centimeter of the upper side of the rails.

[0009] In the case of a web transition, two or more transition plates can be joined together in the direction of the rails. For this purpose, the rubber shaped bodies comprise coupling elements along their transverse edges. Preferably, these coupling elements are designed as grooves and webs, or generally as female and male coupling elements, which are positively engaged with one another after being joined together. Depending on the embodiment, the transverse edges of a rubber body may comprise only female or male or male male and female female coupling elements. In a particularly advantageous embodiment, the rubber shaped bodies comprise metal profiles which are embedded in the region of the transverse edges and which can stabilize the form of the coupling elements and can be screwed together.

[0010] The transition plates according to the invention can be mounted with only a small amount of work at a path transition and, if necessary, can be removed again as easily. For installation, the swell support plates, whose thickness is matched to the dimensions of the rails, the sleepers and the rubber body, are first placed on the sleepers. Thereafter, the rubber shaped bodies are inserted between the rails and joined together. Preferably, the transverse edges of the rubber shaped bodies comprise a weak point in the middle region, for example a V-shaped notch formed between two reinforcing metal profiles at the end face so that the rubber shaped bodies can be slightly bent or elastically deformed for insertion into the gap between the rails. Subsequently, the reinforced concrete panels are inserted into the receptacles of the rubber moldings. Preferably, the reinforced concrete panels comprise one or more threaded sleeves into which hooks or eyelets can be screwed again in a detachable manner for assembly purposes. Because of their great weight, the reinforced concrete panels are held in the gum moldings alone. The inner walls of the rubber moldings and the side walls of the reinforced concrete panels are slightly conical. Due to the weight of the reinforced concrete slab and the additional weight of vehicles which pass through the web transition, the reinforced concrete slab and the rubber shaped body are additionally wedged together in a wedge-locked manner. Optionally, in addition, a form-fitting connection can be established between the rubber shaped body and the reinforced concrete plate,

The transition plates according to the invention transfer the forces exerted by vehicles during travel of the web transition uniformly onto the swell carrier plates and from there to the support regions of the sleepers and the ballast bed. Due to the elastic damping of the transition plates, rail and sill areas are spared. The transition plates are weather-resistant, sound and vibration-absorbing, current-proof and robust and prevent deflections and deformations of the superstructure due to strains caused by road traffic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a section of a rail-like track transition with two transition plates 1, which are clamped between two rails 3 of a track and are connected to one another. The rails 3 and the transition plates 1 are supported on sleepers 5 in a ballast bed (not shown), whereby the connecting regions of adjacent transition plates 1 are preferably arranged above the sleepers 5. Between the rails 3, one or more swell carrier plates 7 lie on the sleepers 5. The thickness or thickness of these swell carrier plates 7 is matched to the type or the dimensions of the rails 3, of the sleepers 5 and of the transition plates 1 in such a way that the transition plates 1 rest on these swivel carrier plates 7.

FIG. 2 shows one of the transfer plates 1 from FIG. 1. Each transfer plate 1 comprises a tub-like rubber-shaped body 9 (FIGS. 4 and 5) and a reinforced concrete plate 11 (FIG. 3) supported in this rubber-shaped body 9. The rubber mold body 9 comprises a tray 9a with one or more recesses 10 and two opposing pairs of side walls 9b, 9c whose upper and lower edges are paired in pairs, and together form a frame. The outflow of leachate is made possible by the recesses 10. The frame delimits an upwardly open and slightly conically widening receiving area for a reinforced concrete slab 11. This receiving area and the reinforced concrete slab 11 are at least approximately parallelepipedal in shape. FIG.

Two threaded sleeves 13, which are inserted into the reinforced concrete plate 11, are accessible from the top surface 11a, which can be used for screwing in detachable hooks or eyelets 15 (FIG. 10). These can be used during assembly and disassembly for lifting and lowering the reinforced concrete slab 11. Preferably, the threaded sleeves 13 are corrosion-resistant. The steel concrete plate 11 completely penetrating threaded sleeves 13 allow water to flow out.

Alternatively, the inlet openings of the threaded sleeves 13 can be sealed, for example, by plugging or in some other way, so that water can not penetrate.

[0017] In the case of a web transition, two or more transmission plates 1 can be connected to one another. For this purpose, the rubber shaped bodies 9 comprise the side walls 9c, which are aligned transversely to the rails 3

Claims

Coupling elements. Preferably, these coupling elements comprise springs 17 and grooves 19, which are formed along the side walls 9c of the rubber-shaped bodies 9, wherein male and female coupling elements interlock positively with one another when mutually adjoining rubber rubber bodies 9 are interjoined. FIG. 6 schematically shows a cross-section in the region of a connecting point of two transfer plates 1, 1 '. The left transfer plate 1 comprises a rubber mold part 9 with male coupling elements. In the latter region, a shoulder protrudes in the lower region of the side wall 9c, on the upper side of which a groove 19 and a spring 17 are formed. [0018] The right transfer plate 1 comprises a rubber mold part 9 with female coupling elements. In the upper region of the side wall 9c, a shoulder protrudes, on the underside of which a groove 19 'and a spring 17' are formed. When the two adjacent transition plates 1 are joined together, the springs 17, 17 'positively engage the grooves 19', 19 of the other transition plate 1, respectively, and the springs 17, 17 'engage behind one another. In principle, both side walls 9c of a rubber shaped body 9 can comprise the same or different coupling elements. To reinforce the springs 17 and grooves 19, metal profiles 21, 23 are embedded in the rubber mold body 9 in the region of the side walls 9c, the shape of which is adapted to those of the coupling elements. Preferably, two such metal profiles 21 and 23 are arranged in the longitudinal direction for each side wall 9c. Between these reinforcing elements, the side walls 9c have weak points for bending or bending the rubber mold body 9 when it is to be inserted into the space between two rails 3. By means of V-shaped notches 25 (FIG. 10) in the centers of the side walls 9c, the bending or bending of the rubber shaped body 9 can be additionally facilitated. Two complementary metal profiles 21, 23 are shown in FIGS. 7 and 8. The one metal profile 21 comprises two nuts 27, the other metal profile 23 has two holes 29 for screws (not shown) aligned with these nuts 27 in the assembled state of the rubber shaped bodies 9, 9 '. In this way, composite rubber mold bodies 9, 9 'can be connected to one another by screws. The screws can be replaced by corresponding openings 31 '(FIG. 6) at the upper side of the side wall 9c '. 9 shows a cross-section of a web transition in the region of one of the rails 3. The side wall 9b of the rubber-shaped body 9 comprises an abutment region 33 adapted to the shape of the rail body between the rail head 3a and the rail base 3b Of the rubber-shaped body 9 adjacent to the rail head 3a serves as a spool. FIG. 10 shows a transition plate 1 inserted into the rail intermediate space, in which two flap eyes 15 are screwed into the threaded sleeves 13 for the purpose of lifting the reinforced concrete plate 11. The shape and size of the transition plate 1 as well as the parts of this transition plate 1 can be determined differently depending on the characteristics and dimensions of the respective track. The width of the reinforced concrete slab 11 and thus also the width of the receiving area in the rubber shaped body 9 in the direction of the side walls 9c is in each case greater than the width of the side walls 9b between the receiving area for the reinforced concrete slab 11 and the contact 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 shaped body 9, the non-positive connections between the rubber shaped body 9 and the rails as well as between the rubber shaped body 9 and the reinforced concrete plate 11 are reinforced by the load of the reinforced concrete panel 11.
