Description

[0001] The present invention relates to a molded body for a track crossing device, which is particularly, but not exclusively, suitable for use in a service track crossing device.

[0002] Service level crossings are level crossings generally located in non-public areas, such as enclosed factory premises, marshalling yards, or connections between platforms in station areas, to allow vehicles and pedestrians to cross railway tracks. Because these service level crossings are generally subject to less stress than level crossings in the public road network (for example, due to the absence of heavy long-distance freight traffic), they are subject to lower requirements regarding structural strength and load-bearing capacity.

[0003] The object of the present invention is to provide a molded body, in particular for a service track crossing device, which has an extended range of functions.

[0004] According to the invention, this problem is solved by a molded body for a track crossing device, in particular for a service track crossing device, comprising a base body constructed with elastic material, with a base body underside to be positioned facing a track system and a base body upper side arranged at a distance in a vertical direction from the base body underside and to be positioned facing away from a track system, wherein the base body is designed in a frame-like manner and surrounds at least one base body opening that completely penetrates the base body from the base body upper side to the base body underside, wherein at least one insert element is received in the at least one base body opening and is fixed to the base body against detachment from the base body.wherein the base body has a base body support surface offset towards the underside in the vertical direction relative to the top of the base body for supporting an insert element support edge provided on the at least one insert element, wherein the distance of the base body support surface to the top of the base body is less than 50% of a maximum distance between the top and bottom of the base body in the vertical direction and / or the thickness of the insert element support edge in the vertical direction is less than 50% of the maximum distance between the top and bottom of the base body in the vertical direction.

[0005] By providing at least one opening in the base body, in which at least one insert element is arranged during operation of a track crossing device constructed with a molded body according to the invention, various additional functions can be integrated into a track crossing device, depending on the insert elements used. For example, water, in particular rainwater and dew, can flow through the molded body via an insert element designed with one or more openings, or moisture accumulating under a track crossing device can evaporate. Furthermore, such an insert element can be used to display various information on the surface of a track crossing device, for example, a warning notice or a company logo.Since, with the insert element removed, the area of ​​the track system positioned beneath the base body is generally accessible, the opening provided in the base body can also be used as an inspection opening for carrying out maintenance or repair work. Because the base body's bearing surface is positioned relatively close to the top of the base body, it is possible to use insert elements that are comparatively thin, for example, plate-like, relative to the thickness of the base body.

[0006] To ensure a stable support of an insert element on the base body, it is proposed that the base body's support surface be oriented essentially orthogonally to the base body's vertical direction.

[0007] Furthermore, for a stable contact interaction between the base body and one or more insert elements, it can be provided that the base body contact surface substantially completely surrounds the at least one base body opening, and / or that the insert element support edge substantially completely surrounds the at least one insert element.

[0008] To further emphasize the possibility of using thin insert elements, the distance of the base body's bearing surface to the top of the base body can be less than 30% of the maximum distance between the top and bottom of the base body in the vertical direction, or / and the thickness of the insert element's bearing edge in the vertical direction can be less than 30% of the maximum distance between the top and bottom of the base body in the vertical direction, or / and the distance of the base body's bearing surface to the top of the base body in the vertical direction can essentially correspond to the thickness of the insert element's bearing edge in the vertical direction.

[0009] For ease of handling, it is particularly advantageous if the maximum thickness of the at least one insert element between an insert element top facing away from a track system and an insert element bottom facing a track system is less than 50% of a maximum distance between the top and bottom of the base body in the vertical direction.

[0010] In order to provide a support interaction effective in the vertical direction between the base body and an insert element even in an area in the vertical direction of the base body below the base body's support surface, it is proposed that the at least one base body opening, starting from the base body's support surface, be designed to taper towards the underside of the base body.

[0011] Efficient support in the vertical direction with a large opening cross-section of the at least one base body opening can be ensured by having a tapering angle of the base body opening between the base body support surface and the underside of the base body with respect to the vertical direction of the base body in the range of 2° to 15°, preferably at about 5°.

[0012] Furthermore, it may be provided that the taper angle of the base body opening between the base body's support surface and the base body's underside is greater than the taper angle of the base body opening between the base body's top surface and the base body's support surface, and / or that the base body opening between the base body's top surface and the base body's support surface is essentially not tapered in the base body's vertical direction. This means that in a region in the base body's vertical direction above the base body's support surface, the base body opening is essentially cylindrical, apart from a comparatively small draft angle that may be required for manufacturing reasons, so that, in particular, plate-like insert elements can be inserted into and removed from such a base body opening relatively easily.

[0013] In order to provide increased structural strength in the base body constructed with elastically deformable material, at least one base body web dividing this base body opening into several opening part areas can be provided in association with at least one base body opening, wherein at least one insert element received in this base body opening extends over the at least one base body web.

[0014] Such a base body web can also be used to support an insert element extending over it, provided that the at least one base body web has an upper surface that is substantially flush with the base body's bearing surface. To avoid conflicts with a track system positioned beneath the base body, it is advantageous if the at least one base body web has an underside that is substantially flush with the base body's underside, thus not extending downwards beyond the frame-like area of ​​the base body surrounding the at least one base body opening.

[0015] To accommodate a clamping unit that ensures the cohesion of several molded bodies, a clamping unit through-opening that completely penetrates at least one base body web, preferably several base body webs, can be provided.

[0016] If it is necessary to make an insert element thicker for reasons of structural stability, it is proposed, in order to avoid a conflict with such a base body web, that at least one insert element has at least one web-receiving recess that at least partially accommodates a base body web.

[0017] To allow the passage of liquid or vaporous media through the molded body, it is proposed that at least one insert element has at least one opening that completely penetrates the base body in the vertical direction. If one or more such insert elements are to be used primarily as information carriers, it is advantageous if at least one insert element is designed without this opening that completely penetrates the base body in the vertical direction.

[0018] Particularly when considering the passage of liquid or gaseous media through the molded body, it is advantageous if at least one insert element is designed in a grid-like manner, preferably as a grid made of, for example, metal material or GRP material.

[0019] Furthermore, at least one such insert element can be constructed with elastic material, for example from the same material as the base body.

[0020] In a further alternative embodiment, at least one insert element may be designed as a plate, preferably a metal or plastic plate. It should be emphasized that, particularly in the case of a plate-like design of an insert element, it may be constructed with several plate parts positioned one above the other in the vertical direction of the base body, and optionally also rigidly connected to one another.

[0021] For a cost-effective yet stable and mechanically and chemically resistant structure, it is proposed that the base body be constructed with bonded rubber granulate, preferably recycled rubber granulate, or recycled material.

[0022] To obtain a very stable surface that is resistant to external influences, the base body can have a core area made up of bonded rubber granulate or recycled material and a shell area surrounding the core area made up of new rubber, i.e., rubber material that was cross-linked for the first time during the manufacture of the base body.

[0023] The base body can be designed in at least one rail adjoining area for installation on a rail of a track system or for receiving a rail adjoining part designed for installation on a rail of a track system.

[0024] A stable connection between the base body and the at least one insert element can be achieved, for example, by fixing the at least one insert element to the base body by positive locking and / or material locking, preferably by gluing.

[0025] For example, a plurality of fastening elements, such as screws, that interact positively with the at least one insert element and / or the base body in the vertical direction of the base body can be provided.

[0026] In order to achieve a substantially step-free transition between the base body and the at least one insert element, it is proposed that an insert element top surface of the at least one insert element connects substantially flush with the base body top surface in the vertical direction of the base body.

[0027] To utilize a function provided by an insert element in a molded body constructed according to the invention as efficiently as possible, it is proposed that the surface area of ​​the molded body provided by the upper surface of the at least one insert element be at least as large as the surface area of ​​the molded body provided by the upper surface of the base body. This means that at least 50%, preferably at least 80%, of the surface area exposed upwards or visible in plan view of such a molded body is provided by the at least one insert element. It should be noted in this context that this refers to the surface projected in the vertical direction of the base body or viewed in cross-section, regardless of any profiling provided on the upper surface of the base body and / or the upper surface of the at least one insert element.

[0028] The invention further relates to a track crossing device, in particular a service track crossing device, for a track system with at least one track comprising two rails, comprising at least one shaped body constructed according to the invention between the two rails of the at least one track, or / and comprising at least one shaped body constructed according to the invention on an outer side facing away from the other rail of at least one of the two rails of the at least one track.

[0029] A stable structure of such a track crossing device can be achieved if at least two shaped bodies adjacent to each other in a longitudinal direction of the two rails of the at least one track are held together by at least one tensioning unit penetrating these shaped bodies in the longitudinal direction of the rails.

[0030] The present invention is described in detail below with reference to the accompanying figures. These show: Fig. 1 a top view of a level crossing device with a plurality of outer shaped bodies positioned next to the rails of a track of a track system and inner shaped bodies positioned between the rails of the track; Fig. 2 a perspective view of a basic body for an inner shaped body of the level crossing device Fig. 1 , viewed from its upper side; Fig. 3 a top view of an internal mold body with the base body of the Fig. 2 ; Fig. 4 a sectional view of the inner mold body of the Fig. 3 , cut along a line IV-IV in Fig. 3 ; Fig. 5 a sectional view of the inner mold body of the Fig. 3 , cut along a line VV in Fig. 3 ; Fig. 6 a perspective view of an alternatively designed basic body for an inner mold body of the track crossing device of the Fig. 1 , viewed from its upper side; Fig. 7 a top view of an internal mold body with the base body of the Fig. 6 ; Fig. 8 a sectional view of the inner mold body of the Fig. 7 , cut along a line VIII-VIII in Figur 7 ; Fig. 9 one of the Fig. 8 corresponding sectional view of an inner molded body with an alternatively designed insert element; Fig. 10 a perspective view of a base body for an outer molded body of the track crossing device of the Fig. 1 , viewed from its upper side; Fig. 11 a top view of an outer molded body with the base body of the Fig. 10 ; Fig. 12 a sectional view of the outer mold body of the Fig. 11 , cut along a line XII-XII in Figur 11 ; Fig. 13 a perspective view of an alternatively designed basic body for an outer molded body of the level crossing device of the Fig. 1 , viewed from its upper side; Fig. 14 a top view of an outer molded body with the base body of the Fig. 13 ; Fig. 15 a sectional view of the outer mold body of the Fig. 14 , cut along a line XV-XV in Fig. 14 ; Fig. 16 one of the Fig. 15 Corresponding sectional view of an outer molded body with an alternatively designed insert element.

[0031] The Fig. 1 Figure 1 shows a schematic representation of a track crossing device 10 on a track 16 comprising two rails 12, 14. The rails 12, 14 may, for example, be supported by sleepers not shown. In relation to track 16, the track crossing device 10 comprises a plurality of shaped bodies 18 arranged longitudinally L of track 16 between the two rails 12, 14 and designed as inner shaped bodies, as well as a plurality of shaped bodies 20 arranged consecutively in a longitudinal direction L of the rail and designed as outer shaped bodies outside the two rails 12, 14. In order to achieve a firm connection of the shaped bodies 18, 20 in the longitudinal direction L of the rail, they can be held together by several clamping units 22, which penetrate the shaped bodies 18, 20 in the longitudinal direction L of the rail and are supported, for example, on the shaped bodies 18, 20 positioned at their ends in the longitudinal direction L.The clamping units 22 can, for example, be rod-shaped and penetrate the clamping unit through-openings in the molded bodies 18 or 20 as described below.

[0032] The shaped bodies 18, 20 are each constructed with a frame-like base body 24, 26 and an insert element 28 or 30 that is carried or fixed to it.

[0033] The structure of the shaped bodies 18, 20, each comprising a frame-like base body 24, 26 and an insert element 28, 30, is described below with reference to the Fig. 2 bis 15 described in detail.

[0034] The Fig. 2 Figure 24 shows a base body for a molded body 18 designed as an inner molded body. The base body 24 is made of elastic material. Preferably, the base body 24 is made of bonded rubber granulate, in particular recycled rubber granulate, or other preferably granular recycled material, which is surrounded on its outer surface by a layer of new rubber, i.e., rubber material that was cross-linked for the first time during the manufacturing process of the base body 24, to provide the outer surface of the base body 24. In its end regions, which are to be positioned transversely to the longitudinal direction L of the rail, the base body 24 has rail-adjoining regions 32, 34 that are positioned adjacent to or engaging under a rail head of the rails 12, 14, so that sufficient space is provided for receiving the wheel flanges of the traction wheels rolling on the rails 12, 14.The rail abutment areas 32, 34 can alternatively be formed on separately designed rail abutment parts, which can be fitted into corresponding recesses of the base body 24. In this way, a shaped body 18 constructed in this manner can be easily adapted to rails 12, 14 of different designs or dimensions.

[0035] At the end areas to be positioned in the longitudinal direction L of the rail, the base body 24 is formed with a tongue and groove profile 36, so that adjacent base bodies 24 interlock in a form-fitting manner in the vertical direction and thus increase the stability of the track crossing device 10.

[0036] The frame-like base body 24 surrounds a base body opening 38, which extends completely through the base body 24 from an upper base body surface 40, to which is to be positioned vertically at the top of the track crossing device 10, to an lower base body surface 42, to which is to be positioned vertically at the bottom. A step-like ledge surrounding the base body opening 38 provides a base body support surface 44, which is offset from the upper base body surface 40 towards the lower base body surface 42.

[0037] The Fig. 3 bis 5 show one with the basic body 24 of the Fig. 2 The assembled shaped body 18. An insert element 28, designed as a plate in the illustrated embodiment example, is provided on the base body 24. The plate-like insert element 28 can, for example, be designed as a metal plate, plastic plate, fiber composite plate or the like and can connect flush with the base body top surface 40 with an insert element top surface 48 in a base body height direction H that essentially corresponds to a vertical direction and completely enclose the shaped body 18 on its upwardly oriented side.

[0038] The insert element 28 and the base body opening 38 that receives it are dimensioned such that at least 50%, preferably at least 80%, of the surface of the molded body 18 visible in plan view is provided by the upper surface 48 of the insert element. The cross-sectional area visible from above is considered independently of any, for example, pyramid-shaped profiles present on the upper surface of the insert element 28 and / or on the upper surface of the base body 24.

[0039] The insert element 28 rests on the base body's bearing surface 44 with a bearing edge 50 that completely surrounds it on its outer circumference. In the case of the insert element 28, which is plate-like and has essentially the same thickness across its entire surface, the thickness d of the bearing edge 50 in the base body's vertical direction H corresponds essentially to a distance A between the base body's bearing surface 44 and the top surface 40 of the base body in the vertical direction H. This can be seen particularly in Fig. 4 that the thickness d or the distance A is significantly smaller than a maximum distance D between the upper surface 40 of the base body and the lower surface 42 of the base body. Preferably, the design is such that the thickness d is less than 50% of the maximum distance D, most preferably less than 30% of the maximum distance D.

[0040] By positioning the base body support edge 44 relatively close to the top surface 40 of the base body, the structural strength of the frame-like base body 24 is essentially unaffected despite the stepped recess for providing the base body support surface 44. At the same time, this positioning of the base body support surface 44 relatively close to the top surface 40 of the base body allows the use of comparatively thin insert elements 28.

[0041] The Fig. 5 Figures a), b), and c) illustrate various, combinable methods for fixing the insert element 28 to the base body 24 by positive locking. Figure 5a) shows the use of a T-profile 52, made of metal, for example, as a fastening element. One vertical leg of the T-profile 52 is inserted into a gap-like space between the insert element 28 and the base body 24, while two horizontal legs overlap the insert element 28 at its upper surface 48 and the base body 24 at its upper surface 40. The T-profile 52 can be fixed to the base body 24, for example, by gluing, screwing, or using expansion anchors or similar devices, so that the insert element 28 is securely anchored to the base body 24 by such a T-profile 52.Such T-profiles 52 can be provided along the entire circumference of the insert element 28.

[0042] Figure 5b) illustrates the fixing of the insert element 28 to the base body 24 by the use of several fastening bolts 54 provided along the support edge 50 of the insert element 28. These bolts can, for example, be designed as screw bolts that extend through corresponding openings in the area of ​​the support edge 50 of the insert element and can be screwed into the structure of the base body 24. Other design variants, such as expansion anchors or the like, can also be used to securely anchor the insert element 28 to the base body 24 at several points along its support edge 50.

[0043] Figure 5c) shows another type of positive-locking connection of the insert element 28 to the base body 24. In this embodiment, a retaining lip 56 is formed on the base body 24 along the outer edge of the base body opening 38 as a fastening element, which overlaps the insert element 28 in the area of ​​its insert element support edge 50. To avoid stepped transitions, a recess 58 to receive the retaining lip 56 can be provided on the upper surface 48 of the insert element. In this embodiment as well, it is advantageous if such a retaining lip 56 extends along the entire outer circumferential edge of the base body opening 38.

[0044] Alternatively or in addition to the various types of positive locking connection of the insert element 28 to the base body 24 described above, it is also possible to realize a direct material-locking connection of the insert element 28 by gluing it to the base body 24.

[0045] An alternative design of a basic body 24 is in Fig. 6 depicted. Also the basic body 24 of the Fig. 6 The base body 24 is fundamentally frame-like and features rail-adjacent areas 32, 34 and tongue-and-groove formations 36, respectively. The base body 24 has a plurality of base body webs 60 extending parallel to the rail-adjacent areas 32, 34. The base body webs 60 are designed such that each has a web top 62 that is flush with the base body support surface 44 in the base body's vertical direction H, and a web bottom 64 that is preferably flush with the base body's lower surface 42 in the base body's vertical direction H. With its web top 62 that is flush with the base body support surface 44, each base body web 60 forms an additional support for an insert element 28 provided on the base body 24. In the Fig. 7 und 8 In the illustrated embodiment, this insert element 28 is designed in a grid-like manner, for example made of metal grating, and therefore has a large number of insert element openings 66 through which water can flow away or moisture accumulating under such a shaped body 18 can evaporate upwards through the opening part areas 68, into which the base body opening 38 is divided by the base body webs 60.

[0046] One can recognize in the Fig. 6 and 8that a tensioning unit passage opening 70 is provided at each of the two outermost base body webs 60, through which the tensioning units 22, which ensure the cohesion of the track crossing device 10, can be guided. Since these tensioning unit passage openings 70 run in the area of ​​the base body webs 60, there is no risk that the adjacent shaped bodies 18 or their base bodies 24 will be deformed by the tensioning force exerted in the longitudinal direction L of the rail.

[0047] Another alternative design of an insert element 28 is in Fig. 9 Illustrated. The insert element 28 of the molded body 18 of the Fig. 9 For example, it is constructed with the same elastic material as the base body 24. This insert element 28 can also comprise a core area made of bonded rubber granulate or recycled material and a surrounding shell made of virgin rubber.

[0048] In order to ensure a higher load-bearing capacity in such an insert element 28 constructed with elastic material, the use of the base body 24 having a plurality of base body webs 60 is necessary. Fig. 6 This is advantageous because the insert element 28 is thus supported at a plurality of positions by the respective upper surfaces 62 of the base body webs 60.

[0049] Furthermore, in this embodiment of the insert element 28, the insert element 28 is designed with a generally greater thickness in the vertical direction H of the base body. In the area of ​​the insert element's support edge 50, the insert element 28 is dimensioned as described above with reference to the Fig. 4 and the plate-like insert element 28 shown there is described. That is, the thickness d of the insert element's support edge 50 corresponds to the distance A of the base body's support surface 44 from the base body's top surface 40. Adjacent to the insert element's support edge 50 is the insert element 28 of the embodiment of Fig. 9 The insert element 28 is shaped to engage in the opening sections 68 of the base body opening 38 between the base body webs 60. For this purpose, the insert element 28 has a web-receiving recess 72 corresponding to each base body web 60.

[0050] In order to further improve the contact interaction with the base body 24 in the vertical direction H, particularly in the case of such an insert element 28 constructed with elastic material, the base body opening 38 is designed such that it has a shape that tapers in the vertical direction H towards the lower surface 42 between the base body's contact surface 44 and the base body's underside 42. The taper angle W of the base body opening 38 between the base body's contact surface 44 and the base body's underside 42 with respect to the vertical direction H can be in the range of 2° to 15°, preferably around 5°.In this way, the elastic insert element 28 is also supported in the vertical direction H of the base body by an insert element support edge 74 which is complementary to this tapered structure of the base body opening 38 and adjoins the insert element support edge 50 on the base body 24.

[0051] This tapered structure of the base body opening 38 is only provided in the base body's vertical direction H below the base body's support surface 44. In the area between the base body's support surface 44 and the base body's upper surface 40, the base body opening 38 is essentially not tapered, thus exhibiting a substantially cylindrical structure, which facilitates the insertion of the insert element 28 into the base body opening 38. This is not contradicted by the fact that, according to the Fig. 5c ) the possibility for positive locking of such an insert element 28 on the base body 24 is provided by a retaining lip 56 on the base body 24 which at least partially overlaps the base body support surface 44.

[0052] The Fig. 9 This illustrates that the tapered structure of the base body 24, which supports the insert element 28, can also be provided in the area of ​​the base body webs 60. Their side flanks can also be inclined, for example, at the same angle W with respect to the base body's vertical direction H, so that the opening sections 68 of the base body opening 38 also taper from the upper web surface 62 to the lower web surface 64. The web receiving recesses 72 in the insert element 28 are shaped accordingly, so that in these mutually complementary angled areas, the insert element 28 is also supported in the vertical direction H of the base body against the side flanks of the base body webs 60.

[0053] It should be noted that even those in the Fig. 7 bis 9 The insert elements 28, which are provided as grating or elastic components, can be attached to the base body 24 in various ways. In particular, they can be in Fig. 5 The possibilities shown for the form-fitting attachment of such an insert element 28 to the base body 24 can be applied, as well as a material-fit connection by bonding, particularly when the insert element 28 is described in Fig. 9 The elastic design shown is present.

[0054] The Fig. 10 bis 16 show various designs of molded bodies formed as external molded parts 20. The Fig. 10 a frame-like base body 26 for such a shaped body 20, the basic structure of which is essentially the basic structure of the one in Fig. 2 The base body 24 shown corresponds to a molded body 18 designed as an inner molded body. The base body 26 of the molded body 20 is also constructed with elastic material, preferably bonded recycled rubber granulate or recycled material, which is covered on its outer surface by a layer of virgin rubber. The base body 26 also has the base body opening 38 extending between the upper surface 40 and the lower surface 42 of the same base body, as well as the base body support surface 44 surrounding the base body opening 38 for supporting a respective insert element 30.

[0055] During the Fig. 11 und 12 In the illustrated embodiment of the molded body 20, the insert element 30 is constructed as a plate of substantially constant thickness, for example, a metal plate, plastic plate, fiber composite plate, or the like, and has the insert element support edge 50 for bearing against the base body support surface 44. In this embodiment as well, the dimensions of the insert element 30 in relation to the dimensions of the base body 26 are preferably selected as described above with reference to the Fig. 4 was explained. The fixing of the insert element 30 on the base body 26 can also be explained in relation to the various preceding statements. Fig. 5 The described methods of a form-fit connection can be implemented. Alternatively or additionally, a material-fit fastening of the insert element 30 can also be achieved by bonding.

[0056] The Fig. 13 bis 15 Figure 1 shows an embodiment of the base body 26 with a base body web 60, the upper surface of which 62 is flush with the base body support surface 44, so that an insert element 30 provided on the base body 26 rests not only on the base body support surface 44, but also on the upper surface 62 of the web and is thus supported. Fig. 14 and 15 Figure 26, in conjunction with a base body 26 having a base body web 60, shows the use of an insert element 30 designed as a grid, in particular a metal grid, which has a plurality of insert element openings 66. Through the insert element openings 66, rainwater or condensation can drain off via the opening section areas 68 of the base body opening 38, or moisture accumulating under the molded body 20 can evaporate upwards.

[0057] The grid-like insert element 30 can also be used, as described above with reference to the Fig. 5 described, are determined by various possibilities of positive locking on the base body 26.

[0058] At the in Fig. 16 In the depicted structure of a molded body 20 constructed as an outer molded body, the insert element 30 is provided as an elastic body, for example, with the same construction material as the base body 26. In order to generate a further support interaction effective in the vertical direction in this configuration, in addition to the support at the base body's bearing surface 44 or the upper surface 62 of the base body's web 60, the base body opening 38 can be tapered at an angle W in its extension between the base body's bearing surface 44 and the base body's underside 42. Similarly, the base body's web 60 can also have side flanks angled at the same angle W, for example, in order to achieve support in the vertical direction of the base body in interaction with the complementarily shaped insert element 30, even in these mutually abutting areas.

[0059] Even with this design of the insert element 30, the preceding statements regarding the Fig. 5 The described options for the form-fitting fixing of the same to the base body 26 and / or the fixing by material bonding, i.e. gluing, can be realized.

[0060] The Fig. 15 und 16 They also show that in the shaped body 20 in the area of ​​the base body web 60 the clamping unit through-opening 70 provided for receiving a clamping unit 22 can be provided, so that the shaped bodies 20 following one another in the longitudinal direction L of the rail can also be held stably together on the outsides of the rails 12, 14.

[0061] The level crossing device described above, with reference to various design forms of the molded parts, can be particularly advantageous for so-called service level crossing devices, i.e., level crossing devices that are not installed in public traffic areas, but, for example, in the area of ​​track systems on factory premises or similar locations. Such service level crossing devices generally experience lower loads in terms of frequency and intensity than level crossing devices intended for use on public roads. This allows the level crossing device to be designed somewhat less robustly by incorporating differently shaped insert elements than is the case with level crossing devices in public traffic areas. The possibility of using such insert elements is advantageous for several reasons.For example, providing openings in the insert elements can facilitate the drainage of water or the evaporation of moisture accumulating under the level crossing device. Alternatively, such insert elements can be used as information carriers, for example, to display warnings or advertising information, such as a company logo, on their upper surface. Depending on the intended use, differently designed insert elements can therefore be used in conjunction with the same base components. Furthermore, the opening in such a component can serve as an inspection opening if system sections of a track layout are located beneath it, requiring access for maintenance work.
