Description

The invention relates to a device for forming a level crossing for crossing a track.

Crossings of a track with streets, paths or squares can be realized without building overpasses or underpasses with level crossings. In order for a level crossing to be passable for road traffic, however, a leveling of height differences in the track grid is necessary, that is, a compensation of the height difference between the surface of the track bed and the running surfaces of the rails. For this purpose, areas in the space between the rails and on their outer sides are typically filled approximately flush up to rail height, with grooves for the flanges of the train wheels remaining in the area near the rails on the side of the rail heads. A well-known procedure is to fix specially manufactured molded bodies in the space between the rails and on their outer sides.

The EP 0 639 670 B1 describes molded body units formed from rubber material for track crossing devices. Outer plates have projections for reaching under the rail heads, while middle plates are held in position by their own weight, complementary tongue-and-groove connections and centering elements. Special measures for fastening to the track bed or track grid are not provided. The device described is designed in particular for bicycle-friendliness. In the case of greater loads, for example from cars or trucks, there is, however, the risk that panels will slip, for example as a result of forces when braking or accelerating the vehicles or deformation of the panels, for example due to loading, aging or temperature fluctuations. Panels can also be lifted upwards by unauthorized persons or jump out upwards in the event of one-sided extreme loads.

The EP 0 281 013 B1 shows plates for level crossings, which can consist of a relatively rigid and hard elastic material and which have expansion folds. The expansion folds are realized by grooves in particular in the upper plate surface. These grooves can, however, represent undesirable depressions in the roadway, which in turn can be dangerous in particular for cyclists or pedestrians with high heels and also act as collecting points for dirt. In the case of large forces when braking or accelerating motor vehicles, there is again the risk of plates slipping. There is also the possibility that unauthorized persons could lift the panels upwards. Underneath the plates there is a substructure made of wooden blocks and shaped rail pieces that cover the threshold fastening devices, so that the construction of a level crossing is relatively complex overall.

In the EP 1 225 279 A2 a track crossing construction is shown with which a track crossing is formed from a plurality of individual closely spaced molded bodies which are connected to one another in the longitudinal direction of the track with mechanical connecting means. The mechanical connecting means are designed in the form of brackets and are adjustable in the longitudinal direction of the track and are connected to one another and to a sleeper at one point. Appropriately, only a single retaining clip should be fixed in a row of molded bodies on a threshold. However, the stability achieved in this way can sometimes not be sufficient for heavily used level crossings. It is also disadvantageous that the shaped bodies are not effectively secured against being lifted upwards, so that they could be removed by unauthorized persons.

The EP 0 904 463 B1 describes a device for fixing the position of shaped bodies of a track crossing device following one another in a longitudinal direction of the track system. The shaped bodies are coupled together to form a structural unit by means of a fixing rod means which extends in the longitudinal direction of the track system. At or near the end regions of the fixing rod means, end contact means are permanently coupled or can be permanently coupled and can be brought into contact with a respective end face of the last shaped body in the longitudinal direction. Furthermore, at least one intermediate contact means is provided, which is firmly coupled or can be firmly coupled to the fixing rod means between the end regions and can be brought into contact with a provided contact surface on one of the molded bodies. Overall, a large number of special components are provided for fixing shaped bodies in position. The system is therefore relatively complex, as a result of which the construction of track crossing facilities can be relatively complex and the training of the relevant personnel can be costly. Different variants of fixing rod fasteners are also described, which are intended for different types of sleepers. Fixing rod fasteners for concrete or metal sleepers are only placed on such sleepers; Associated molded bodies can thus be lifted out upwards together with the fixing rod. The fixing of the position of the shaped bodies can also be in need of improvement for heavily used level crossings.

The U.S. 1,613,850 relates to a road surface at level crossings to provide a smooth and durable surface in a plane with or without an obstruction to the running surface of the rail. To do this, a U-shaped plate is fastened with bolts through the rail web. The plate also has an extended base flange which overlaps the rail foot and whose front end has reached the sleeper and is nailed there. The disadvantage here is that the plate cannot be removed again in a simple manner.

It is therefore an object of the invention to provide a device to form a level crossing in which the disadvantages described are avoided, which is particularly stable in the installed state, which prevents slipping of molded bodies along and across the track and lifting them out excludes above, which prevents the formation of gaps between the shaped bodies, which comprises as few components as possible and / or which can be easily installed and removed again several times.

This object is achieved by the subjects of the independent claims. Advantageous further developments of the invention are the subject matter of the dependent claims.

A device is provided for forming a level crossing to cross a track. The device comprises a molded body and a molded body holder which can be attached to a rail, the molded body holder comprising two holding jaws which can be attached to the rail on both sides of the rail in opposition to one another.

In the following, a device which is helpful for a better understanding of the invention is described in which the molded body can be releasably fixed on at least one of the rails by means of a transverse bore through the rail web. The person skilled in the art can see that the device is included both in the case that a transverse bore, by means of which the molded body can be fixed to the rail, and in the case that a molded body holder is included, by means of which the molded body can be fixed on the rail, with each other have interchangeable features and can be combined with one another.

The track crosses at the level of the track itself, so it is a level crossing of the track in contrast to an underpass or an overpass.

A track to be crossed represents a roadway for rail vehicles that extends along a track bed, in particular for vehicles that mechanically be guided with wheels on the rails, such as railways or rail-bound local public transport such as trams or underground trains. A track line over which a level crossing can be formed by means of the device is accordingly in particular a railway, tram or underground line. A track section can have one or more, in particular parallel, tracks. A track in turn typically comprises two parallel rails, for example on sleepers. A track can sometimes also include more than two rails, for example in the case of triple or multi-rail tracks on which rail vehicles of different track widths are used, or in the case of traction power supply to the railcars by means of additional busbars. As a rule, the rails are attached to sleepers made of wood, concrete, steel or plastic, which are regularly spaced in the track bed. The track grid formed from rails and sleepers is typically stored in a track bed made of gravel.

The device is especially designed to cross a track with a traffic area for motorized and / or non-motorized road users, so that the road users can cross the track via the level crossing. The traffic area crossing the track is a street, a path or a square or a sub-area thereof which is intended for certain road users, for example the roadway, the bicycle path or the pedestrian path of a street. The level crossing is intended for motorized road users (motor vehicles such as cars and trucks, motorcycles, mopeds, etc.) and / or non-motorized road users (cyclists, pedestrians, riders, etc.). The device is accordingly designed in such a way that a level crossing that can be driven and / or walked across can be formed, which crosses rails and is easily passable for various road users.

The device is designed to cross a track which comprises at least two rails. This is typically a pair of rails on a track. However, it can also be two rails of different, in particular adjacent, tracks. The rails each have a rail foot, a rail head and a rail web connecting the rail head and the rail foot to one another. They are preferably Vignole rails (broad-base rails) used as railway rails, tram rails or underground rails. However, other types of rails can also be considered, such as grooved rails, thick web rails, crane rails, tongue rails, solid rails, block rails, rectangular rails.

The device comprises at least one intermediate rail shaped body which can be re-inserted and removed again and is arranged between the two rails when the device is installed. Furthermore, the device comprises at least one multiple insertable and removable first and second rail outer molded body which adjoin the outer side of the first and second rail, respectively, when the device is installed. In the installed state, the molded bodies are arranged in such a way that the first outer rail molded body, the intermediate rail molded body and the second outer rail molded body together form the or part of the traffic area of the level crossing, e.g. in a horizontal continuation of the road surface, across the rails.

It is evident to the person skilled in the art that a track to be crossed can also comprise more than two rails, in particular several parallel tracks. In the case of two tracks that are each designed as a pair of rails, the traffic area of the level crossing can be formed in that an intermediate rail molding is arranged between the two rails of each track, and a first rail outer molding is arranged between the tracks, that is adjoining both the outside of the second rail of the first track and the outside of the first rail of the second track, furthermore a second rail outside molding adjoins the outside of the first rail of the first track and finally a third rail outside molding adjoining the outside of the second rail of the second track is adjacent.

A traffic area of the level crossing formed by the drivable and / or accessible preferably plate-shaped molded bodies closes a gap caused by the track in a traffic area crossing the track, for example a street. Accordingly, a traffic area formed with shaped bodies is prepared to enable motorized and / or non-motorized road users of the intersecting traffic area to easily pass transversely, in particular vertically, over the rails of the track section, but not to allow non-rail-bound vehicles to drive along a lane of the rails.

Furthermore, the device, which is helpful for a better understanding of the invention, comprises at least one transverse bore through the rail web of at least one of the two rails in the region of one of the adjacent molded bodies. The transverse bore is a hole drilled into the rail web, which is transverse, preferably perpendicular, to the longitudinal direction of the Rail runs through the rail web so that the two rail chambers communicate with one another on both sides of the rail.

Finally, the device, which is helpful for a better understanding of the invention, comprises at least one fastening means which extends through the transverse bore in the rail web of the rail, one of the molded bodies being releasably attachable or fastened to the rail by means of the fastening means through the transverse bore. The fastening means accordingly extends transversely, preferably perpendicularly, to the longitudinal direction of the rails through the transverse bore. The molded body which can be fastened by means of the fastening means expediently has a receiving device for the fastening means, into which the fastening means engages. With the fastening means, the said molded body can be connected to the rail in a detachable but firm manner, in particular without play. The molded body is accordingly fixed to the rail in all directions by the fastening means, that is to say in the direction longitudinal to the rail, in the horizontal direction transversely to the rail and in the vertical upward direction. In the vertically upward direction, the molded body is preferably fastened essentially exclusively by the at least one fastening means, that is to say, according to an exemplary embodiment, not by the molded body engaging in the rail chamber. The shaped body is also preferably secured in the direction longitudinal to the rail exclusively by the at least one fastening means, that is, according to an exemplary embodiment, not in that the shaped body is coupled together with other, adjacent shaped bodies extending along the rail. Finally, the molded body is also fastened in the horizontal direction transversely to the rail, preferably exclusively by the at least one fastening means.

The shaped body fastened by means of the fastening means through the transverse bore is accordingly fastened directly to the rail and is thus fixed in a particularly stable manner against slipping along and across the rail.

For the construction of level crossings, in particular with rubber-elastic molded bodies, it has proven to be particularly advantageous to attach at least one or some of the molded bodies directly to the rail in order to ensure a high level of stability of the level crossing, especially for crossing with heavy vehicles.

Since the fastened molded bodies are fastened to the fastening means in all directions, they are also secured in a stable manner against lifting out or jumping out upwards as a result of strong one-sided loads.

The fastening described goes hand in hand with a transverse drilling through a rail web. It has been found that such regular transverse bores through the rail webs do not represent an unacceptable impairment of the stability of the rail, even with Vignole rails.

The device for forming the level crossing is designed so that the level crossing can be installed and removed again several times. In this way, the fastening means can be released again in order to release the releasably fastened molded body from the rail. Furthermore, all molded bodies can be removed again from the associated rail.

The possibility of being able to easily install and remove the level crossing several times is an advantage in order to be able to carry out maintenance or repair work on the track section or on the track bed in the area of the level crossing, in particular to ensure that the railway sleepers are shored with gravel, ie to tamp the track bed.

Another advantage of the device is the small number of different components. This enables inexpensive manufacture and simple installation and removal of the level crossing.

In one embodiment of the device which is helpful for a better understanding of the invention, the fastening means is designed as a fastening screw. The fastening screw extends through the transverse bore in the rail web and can be screwed into the shaped body that can be fastened by means of the fastening means in order to screw this shaped body firmly to the rail web.

A fastening screw transversely through the rail web represents a particularly simple way of securely but detachable fastening of molded bodies.

The molded body which can be fastened by means of the fastening means can particularly preferably have a threaded insert on its narrow side facing the rail, so that the fastening screw can be screwed into the threaded insert. A secure screw connection, in particular in a molded body made of a rubber elastic material, can also be ensured in other ways, for example by means of a transverse nut.

Of course, the at least one fastening means embodied as a fastening screw can, depending on the material of the shaped body, in particular in the case of a shaped body made of wood, be screwed directly into it without a threaded insert.

In a further development of the device, which is helpful for a better understanding of the invention, at least one of the shaped bodies, which is opposite the shaped body that can be fastened by means of the fastening means on the other side of the same rail, is locked on the fastening means in a direction along the perpendicular to prevent this shaped body from being lifted out secure above.

Said molded body is accordingly locked on the fastening means in such a way that it is secured against vertical movement upwards. The said shaped body remains movable in particular in the direction longitudinal to the rail.

In another further development of the device, which is helpful for a better understanding of the invention, at least one of the shaped bodies, which is opposite the shaped body on the other side of the same rail that can be fastened by means of the fastening means, is locked on the fastening means in a direction transverse to the perpendicular and transverse to the track in order to prevent it Secure molded body against horizontal removal away from the rail.

Said molded body is accordingly locked on the fastening means in such a way that it is secured against horizontal movement away from the rail. The said molded body, however, in turn remains movable in particular in the direction longitudinal to the rail.

If the said molded body is against vertical movement upwards, ie along the perpendicular, as well as against horizontal movement away from the rail, ie transversely to the perpendicular and transversely to the track, there is only one-dimensional freedom of movement along the rail, if so desired is.

As a result of the freedom of movement along the rail, the corresponding molded bodies can still be repositioned in the direction of the rail after locking. As a result, such a shaped body can, in particular afterwards, be moved precisely to the position of the shaped body which is opposite it and which is fastened to the same rail by means of the fastening means.

The device, which is helpful for a better understanding of the invention, can also comprise a holding means, in particular a holding block or a holding bracket, on which the at least one shaped body, which is opposite the shaped body which can be fastened by means of the fastening means, is locked on the other side of the same rail, the holding means is attached to the fastener.

The said molded body is therefore only locked indirectly to the fastening means. It is, however, locked directly to the holding means, which in turn is attached to the Fastening means is attached. If the fastening means is designed as a fastening screw, the holding means can for example be fastened under the screw head of the fastening screw when the screw is firmly tightened. The holding means can have engagements, grooves, holes, hooks or the like in order to lock the elongated securing means thereon.

By using a holding means, the fastening means can be designed particularly simply, for example as a standard screw or a threaded pin. In addition, the flexibility in building level crossings is increased. If desired, retaining means and thus locking options can, for example, only be attached to some of the fastening screws. It can be provided, for example, that the molded bodies opposite the fixed molded bodies on the same rail have an integral multiple of the width of the fixed molded bodies and are not locked to each fastening means.

In one embodiment of the device, which is helpful for a better understanding of the invention, at least one of the shaped bodies, which is opposite the shaped body on the other side of the same rail that can be fastened by means of the fastening means, has a longitudinal channel along the track. An elongated securing means extends through the longitudinal channel along the track and is locked in at least one direction on the fastening means. The elongated securing means can in particular be a rod, a tube, a wire or a rope. The longitudinal channel can be designed as a longitudinal bore through the respective molded body.

The elongate securing means can be locked on the fastening means in a direction longitudinal to the perpendicular in order to prevent movement in this direction and to secure the corresponding molded body against being lifted upwards. The elongated securing means can additionally or exclusively be locked in a direction transverse to the perpendicular and transverse to the track section in order to prevent movement in this direction and to secure the corresponding molded body against horizontal removal away from the rail.

The elongate securing means can be locked directly on the fastening means. A direct locking can be implemented, for example, in that the elongate securing means extends through the longitudinal channel of the corresponding molded body along the track and engages under the fastening means.

The fastening means can also be designed as a fastening screw and have a screw head and the elongated securing means engage behind the screw head in order to prevent the molded body or bodies with the longitudinal channel from being horizontally removed away from the secure the respective rail. A nut screwed onto a threaded pin can also take the place of a screw head.

In particular, the fastening screw can have a special head with a groove and the elongated securing means can engage in the groove of the special head of the fastening screw in order to secure the shaped body or bodies with the longitudinal channel against horizontal removal away from the respective rail.

It is also possible that the fastening screw is designed as an eyebolt with an annular head and the elongated securing means engages in the ring in order to secure the molded body (s) with the longitudinal channel against lifting upwards and against horizontal removal away from the respective rail at the same time.

The elongated securing means can also only be locked indirectly to the fastening means. An only indirect locking on the fastening means can be implemented, for example, in that the elongate securing means engages the holding means, which in turn is fastened to the fastening means.

Furthermore, a spacer can be included, which holds the screw head of the fastening screw on the rail side opposite the shaped body which can be fastened by means of the fastening means at a distance from the rail web when the fastening screw is tightened and screwed firmly to the threaded insert of the shaped body. The holding means can function as a spacer when it comes to rest on the rail web.

In a further development of the device, which is helpful for a better understanding of the invention, a first and a second group of identical first and second rail outer-side molded bodies and a third group of identical intermediate rail molded bodies are included. The shaped bodies each extend adjacent to one another along the respective rail, so that the first, third and second group of shaped bodies form the traffic area of the level crossing across the rails in a two-dimensional grid. The width of the traffic area of the level crossing corresponds to the width of the groups of shaped bodies lying next to one another in the direction of the track.

A level crossing made up of groups of similar shaped bodies can advantageously be built in a desired width modularly from a small number of different shaped bodies. As a result, only moldings with one or a few standard widths need to be produced in the factory. Preferably these widths are based on the threshold distance. In particular, provision can be made to use molded bodies whose widths correspond to integral multiples (n> = 1) of the threshold distance.

The shaped bodies of a group are accordingly arranged directly abutting one another in the track direction, while the first and third group and the third and second group of shaped bodies are each separated from one another by the first and second rails. Each of the groups of shaped bodies preferably comprises an equal number of shaped bodies. The two-dimensional grid of shaped bodies can in particular be a two-dimensional matrix.

In this further development of the device, which is helpful for a better understanding of the invention, at least one transverse bore is provided through the associated rail web for each shaped body of one or two of the groups, the transverse bores being drilled through the rail web or rails with a regular grid spacing. Furthermore, at least one fastening means is provided, by means of which the respective molded body can be detachably fastened to the rail, each fastening means extending through the respective transverse bore in the rail web.

Those molded bodies for which a transverse bore and a fastening means are provided can thus each be fastened or fastened to the associated rail or rails by their own fastening means, i.e. independently of one another. As a result, these molded bodies can advantageously be attached individually and also individually detached again. This not only ensures excellent stability of the level crossing, but also enables particularly easy maintenance. For example, only some of the molded bodies can be removed in order to make certain areas of the track bed accessible, or just individual molded bodies can be replaced without loosening other attached molded bodies.

The shaped bodies of the group or groups of shaped bodies which cannot be fastened with the fastening means through the respective transverse bore in the associated rail web preferably have the same longitudinal channel, so that the elongated securing means extends through the longitudinal channel of all shaped bodies of this group and to the Fastening means is locked in a direction along the perpendicular to secure this group or groups of shaped bodies against lifting out upwards.

In other words, the group or groups of shaped bodies which are not fastened with the fastening means through the respective transverse bore in the associated rail web have continuous longitudinal channels extending over the width of the group or groups, through which a single or a plurality of Individual parts composed elongated securing means extends, the length of which preferably corresponds to at least the width of the associated group. Such an elongated securing means, which extends through a plurality of shaped bodies arranged next to one another in the track direction, secures these shaped bodies against vertical movement upwards and preferably also against horizontal movement away from the rail. It should be noted, however, that these molded bodies are preferably not coupled or connected to one another in the track direction by the elongated securing means. Rather, the shaped bodies preferably remain movable in the track direction independently of one another, like pearls on a string.

One advantage of such mobility in the direction of the track is that the corresponding molded bodies can still be repositioned in the direction of the rail after locking, e.g. precisely to the position of the molded bodies opposite them on the same rail.

There are basically different ways of assembling the three groups of molded bodies. One possibility is to fasten the first and second outer rail moldings to the first and second rail by means of fastening means through transverse bores, the fastening means being connected to the outer rail moldings from the inside of the rail through the transverse bores. The intermediate rail shaped bodies can then be secured against lifting out upwards with two elongated securing means.

Another preferred possibility is to fasten the intermediate rail shaped bodies to the first and second rails, the fastening means being expediently connected to the intermediate rail shaped bodies from the outside of the rail through the transverse bores. The shaped bodies on the outside of the rail can then each be secured with an elongated securing means against lifting out upwards.

Accordingly, the intermediate rail shaped bodies are preferably fastened with the fastening means either to one rail or to both rails through the transverse bores in the rail webs and an elongated one extends in each case Securing means through the longitudinal channel of the first and / or second rail outer side moldings and is locked on the respective fastening means in a direction longitudinal to the perpendicular to secure the first and / or second rail outside moldings against lifting out upwards.

In one embodiment of the device which is helpful for a better understanding of the invention, the intermediate rail shaped body or bodies, the first and / or second rail outer shaped body or bodies are supported on the rail foot of the respective rail.

Accordingly, these molded bodies preferably extend in the area near the rail from the rail head to the rail foot and lie directly on the rail foot. This is particularly the case with Vignole rails whose rail foot is wider than the rail head. In this way, a high level of stability of the traffic area in the area close to the rails is guaranteed, in particular without additional components below the molded body.

The at least one shaped body that can be fastened by means of the fastening means preferably has recesses on its underside for the rail foot fastening devices.

Rail foot fastening devices are to be understood as meaning, in particular, rail foot fastening clamps and rail foot fastening screws with which the rails are fastened to the sleepers.

Furthermore, the at least one molded body with the longitudinal channel preferably has recesses on its underside for the rail foot fastening devices and at least one recess for the at least one fastening means.

The at least one recess for the fastening means is preferably located on the underside of the at least one molded body with the longitudinal channel.

Particularly preferably, the recesses for the rail foot fastening devices and / or for the at least one fastening means are not continuous, but rather discretely formed along the track, so that the molded bodies between the recesses extend in one piece to the rail foot and are supported on the associated rail foot.

The recesses are accordingly intermittent as seen in the track direction, in particular only in the area of the rail foot fastening devices or the fastening means intended. This ensures high stability of the traffic area in the area close to the rails.

The cutouts are spaced from one another in the direction of the rail, which correspond to the spacing of the rail foot fastening devices or the fastening means. The recesses are accordingly typically equidistantly spaced.

In a further development of the device, which is helpful for a better understanding of the invention, the intermediate rail molded body, the first and / or second rail outer molded body do not engage in the rail chamber formed between the rail head and the rail foot and do not fill the rail chamber, so that the intermediate rail Molded body, the first and / or second rail outer molded body can be lowered vertically from above down to the rail foot during installation without having to be threaded into the rail chamber.

The intermediate rail shaped body is expediently arranged in a centered manner between the two rails and can adjoin both rails, thus essentially completely filling the space between the two rails. The intermediate rail molding can also come to rest on the insides of the two rails, but preferably only on the rail feet and the rail heads, particularly preferably exclusively on the rail feet. The intermediate rail shaped body preferably does not (or only minimally) engages in the rail chamber, so that it can be inserted between the rails from above and removed from above without being (almost) deformed. Furthermore, a track groove preferably remains on the rail head, which can accommodate the flange of the pulling wheels. The first and second rail outer shaped bodies can also come to rest on the outer side of the first or second rail, but preferably only on the respective rail foot and rail head. The rail outside moldings in turn preferably do not (or only minimally) engage in the rail chamber, so that the rail outside moldings at least in the area near the rail can be inserted (almost) without deformation from above and removed upwards. Since the shaped bodies do not (or only minimally) engage in the rail chambers, even relatively hard and rigid shaped bodies can be assembled and dismantled again without any problems.

In a further development of the device, which is helpful for a better understanding of the invention, at least one chamber filling element is included, which fills the rail chamber formed between the rail head and the rail foot. So they are Chamber filling elements arranged between the rail web and the respective molded body. The intermediate rail shaped body, the first and / or second rail outer side shaped body comes into contact with the chamber filling element with its narrow side facing the rail.

Since the rail chambers are filled with chamber filling elements, the sound insulation and the fixation of molded bodies adjoining them, in particular transversely to the track direction, can be additionally increased.

The at least one chamber filling element is preferably made of rubber-elastic material, bonded rubber granulate or vulcanized rubber. The chamber filling element also preferably has at least one transverse channel which, in the installed state, is aligned with the cross hole or holes in the rail web, so that the fastening means extends through the transverse channel of the chamber filling element and through the cross hole in the rail web when the one with the fastening means attachable molded body is attached to the rail.

The chamber filling element can in particular have a length which corresponds to the width of a group of shaped bodies arranged next to one another along the rail. The chamber filling element then preferably has a corresponding number of transverse channels so that each molded body of a group can be fastened with fastening means.

In one embodiment of the device, which is helpful for a better understanding of the invention, the shaped body with the longitudinal channel has at least one recess, in particular on its underside, for the at least one fastening means and the shaped body with the longitudinal channel engages behind a thickening of the fastening means, e.g. the screw head, around the To lock the molded body with the longitudinal channel on the fastening means transversely to the track section when the molded body with the longitudinal channel is mounted on the rail.

In a further embodiment of the device, which is helpful for a better understanding of the invention, the molded body with the longitudinal channel has at least one recess, in particular on its underside, for the at least one fastening means and the at least one recess for the at least one fastening means is designed to fit the fastening means, in order to lock the molded body with the longitudinal channel on the fastening means along the length of the track when the molded body with the longitudinal channel is mounted on the rail.

In the event that at least one holding means is included, the at least one recess can also be provided at the same time for the at least one fastening means and the at least one holding means. It can also be provided that the molded body with the longitudinal channel has an additional recess for the at least one holding means, which is designed to fit the holding means with an exact fit.

By locking a plurality of molded bodies with a longitudinal channel along the track by means of precisely fitting recesses for the fastening means and / or the holding means, each of these molded bodies is advantageously locked independently of one another. This ensures a high level of stability of the level crossing.

The intermediate rail molded body, the first and / or second rail outer molded body are preferably made from rubber-elastic material, bonded rubber granulate, vulcanized rubber, wood, concrete, asphalt, or a combination thereof. Polyurethane-bonded rubber granules are particularly preferred. The shaped bodies preferably have a dark shade, in particular dark gray or black.

Depending on the material, the threaded insert is preferably screwed into the material of the intermediate rail molding or molded into the material during production, e.g. when pressing bonded rubber granulate.

An intermediate rail molding or rail outer side molding is also provided for forming the level crossing, which comprises a threaded insert on its narrow side facing the rail in order to screw the intermediate rail molding or rail outside molding to the respective transverse bore in the rail web.

Furthermore, a method that is helpful for a better understanding of the invention is provided for building a level crossing by installing a device as described. At least one intermediate rail shaped body, at least one first and second rail outer shaped body and at least one fastening means are provided. Furthermore, at least one transverse hole is made on the built-in rail on site through the rail web of at least one of the two rails. The intermediate rail molding is placed between the two rails and the first and second rail outside molding are placed adjacent to the outside of the first and second rails, respectively, with at least one of the molding on an associated rail by means of the fastening means through the transverse bore in the rail web Detachable rail is attached. The molded bodies are placed in such a way that the first rail outer molded body, the intermediate rail molded body and the second rail outer molded body form the or part of the traffic area of the level crossing across the rails.

In a further development of the method, which is helpful for a better understanding of the invention, at least two fastening means are provided and at least one transverse bore is made through the rail web of each of the two rails.

In a first variant, after the two transverse bores have been produced, the intermediate rail molding is placed between the two rails and releasably fastened to the two rails by means of one of the fastening means through the transverse bore in the rail web of the respective rail. The first and second rail outside moldings are then placed adjacent the outside of the first and second rails, respectively.

In a second variant, after the respective transverse bore has been produced, the first and second rail outer molded bodies are placed adjacent to the outside of the first and second rails and releasably attached to the first and second rails by means of one of the fastening means through the transverse bore in the rail web releasably attached to the respective rail. The intermediate rail molding is then placed between the two rails.

In both variants, the first outer rail shaped body, the intermediate rail shaped body and the second outer rail shaped body form the or part of the traffic area of the level crossing across the rails.

In the first variant, provision can be made to provide at least one first and second outer rail shaped body, each with a longitudinal channel. These molded bodies are placed adjacent to the outside of the first or second rail, so that the longitudinal channel runs lengthways along the track, and then each secured against being lifted upwards by inserting an elongated securing means into the longitudinal channel along the track and on is inserted engaging the respective holding means.

In the second variant it can be provided to provide at least one intermediate rail shaped body with two parallel longitudinal channels. This molded body is placed between the two rails so that the two longitudinal channels run lengthways along the track run, and then secured against being lifted upwards by inserting an elongated securing means into each of the two longitudinal channels along the track and engaging with the respective holding means.

In a further development of the method, which is helpful for a better understanding of the invention, a first and second group of similar first and second rail outer side moldings and a third group of similar intermediate rail moldings as well as at least one fastening means for each molding of one or two of the groups are provided . Furthermore, at least one transverse bore is produced for each shaped body of one or two of the groups through the associated rail web, the transverse bores being drilled through the rail web or rails with a regular grid spacing.

The moldings of the first, third and second group are placed next to one another along the respective rail so that they form the traffic area of the level crossing across the rails in a two-dimensional grid. The width of the traffic area corresponds to the width of the groups of shaped bodies lying next to one another in the track direction.

Furthermore, each molded body is releasably fastened by one or two of the groups to the associated rail by means of the respective fastening means through the respective transverse bore in the rail web.

It can be provided to use a template in order to drill the transverse bores with a regular grid spacing through the rail web (s).

Furthermore, a method for maintaining a track in the area of a level crossing, which is helpful for a better understanding of the invention, is provided, the level crossing being formed by the device described and / or being constructed by the method described.

In the method for maintaining the track, if one or more molded bodies secured against being lifted out are present, the molded body or bodies secured against being lifted upward are unlocked by removing the respective elongated securing means and removed from the rails and preferably away from the Rails kept. Furthermore, the releasably fastened molded body (s) are detached from the associated rail by removing the respective fastening means and are also removed from the rails and preferably stored away from the rails. The track bed is then maintained, for example by tamping the track bed in the area of the level crossing, in particular by means of a track tamping machine.

Finally, the level crossing is rebuilt according to the method presented above, although the production of the transverse bore (s) can be omitted. The existing cross-hole (s) are therefore reused.

In general, it is not absolutely necessary for one or more of the molded bodies to be fastened through the rail web by means of transverse bores in order to achieve the initially described object which the invention has set itself or to achieve the advantages that have already been described.

It can also be provided, for example, that a molded body is fixed directly to a rail, that is to say in particular not just to a threshold, by means of a molded body holder fastened to a rail. In general, a particularly high level of stability of the traffic area can be ensured by securing a shaped body directly on a rail with a suitable additional component. As a result, the shaped body can be prevented from lifting out or jumping out upwards, particularly in the area close to the rails, even if extreme loads occur.

Accordingly, more generally, a device for forming a level crossing which is helpful for a better understanding of the invention is provided which comprises at least one molded body and either at least one molded body holder which can be attached to one of the two rails or at least one transverse bore through the rail web of at least one of the two Comprises rails, the molded body being releasably fixable on at least one of the two rails either by means of the molded body holder or by means of the transverse bore on the rail. The molded body can therefore in particular be fastened or locked to one of the rails.

A person skilled in the art can see that this device is included both in the case that a transverse bore, by means of which the molded body can be fixed to the rail, and in the case that a molded body holder is included, by means of which the molded body can be fixed on the rail, with each other have interchangeable features and can be combined with one another. In particular, the shaped body can accordingly be locked on the shaped body holder in a direction along the perpendicular, ie vertically, in order to secure the shaped body against being lifted out upwards. Alternatively or in addition, the shaped body can be in a direction transverse to Be locked perpendicular and across the track to secure the molded body against horizontal removal away from the rail.

For this purpose, it can be provided, for example, that the molded body has a longitudinal channel along the track, with an elongated securing means extending through the longitudinal channel along the track and on the molded body holder in a direction along the perpendicular and / or in a direction transverse to the Is locked perpendicular and transversely to the track, in particular by engaging the elongated securing means on the molded body holder.

The invention relates to a device for forming a level crossing comprising at least one shaped body, the shaped body being releasably fixable on the rail on at least one of the two rails by means of the shaped body holder.

According to the invention, the molded body holder further comprises two holding jaws which can be fastened to the rail on both sides of the rail in opposition to one another. As a result, a molded body can be fixed to the rail on both sides of the rail by means of the molded body holder, more precisely by means of the respective holding jaw. In other words, one holding jaw can be attached to the outside of the rail and the other holding jaw on the inside of the rail. A shaped body can thus be fastened or locked on the outer and inner holding jaws so that one shaped body adjoins the outside of the rail and is fixed there and the other shaped body adjoins the inside and is fixed there.

The two holding jaws, i.e. the outer and inner holding jaws, of the molded body holder are furthermore shaped according to the invention in such a way that they clasp the rail foot. The retaining jaws can also be braced with one another and / or with the rail, in particular the rail foot. For example, the holding jaws can be clamped together like a screw clamp, so that the rail, in particular the rail foot, is clamped between the two holding jaws when the molded body holder is attached to the rail. To clamp the holding jaws, a tensioning screw can be provided, which expediently runs below the rail foot across the rail and connects and braces the two holding jaws with one another.

The molded body holder can be designed as a walking protection clamp, which can be mounted in particular on the rail foot by screwing, wedging or clamping.

In a further development, the device comprises a total of at least two shaped body holders, one of the two shaped body holders being fastened to each of the two rails. The molded body holders in turn each comprise two holding jaws. Furthermore, a total of at least three shaped bodies are included. One of the molded bodies is arranged between the two rails, i.e. designed as an intermediate rail molded body, and fixed, in particular fastened or locked, to both rails by means of both molded body holders, in particular the two inner holding jaws of the two molded bodies. The other two of the molded bodies each adjoin one of the outer sides of the two rails, i.e. are designed as rail outer molded bodies and are each fixed to only one of the two rails by means of only one of the two molded body holders, in particular the respective outer holding jaw.

Preferably, a first and second group of shaped bodies each adjoining one of the outer sides of one of the two rails, ie rail outer side shaped bodies, and a third group of shaped bodies arranged between the rails, ie intermediate rail shaped bodies, which are each adjacent to one another along the each rail so that the first, third and second group of shaped bodies form the traffic area of the level crossing across the rails in a two-dimensional grid, wherein the width of the traffic area of the level crossing can correspond to the width of the groups of the adjacent shaped bodies.

It can then be provided that the molded bodies of at least one of the groups have the same longitudinal channel, so that the elongated securing means extends through the longitudinal channel of all molded bodies of this group and is locked on the molded body holder in a direction along the perpendicular to to secure this group of shaped bodies against lifting out upwards.

In particular, in order to achieve a high level of stability in the area close to the rail, it can be provided that the shaped body or bodies are supported on the rail foot of the respective rail in the installed state. For this purpose it can further be provided that the shaped body or bodies have recesses on their underside for the rail foot fastening devices and / or at least one recess for the shaped body holder.

The recesses for the rail foot fastening devices and / or the molded body holder do not need to be formed continuously along the track. It can, in particular to increase the stability or to provide a suitable Longitudinal channel, it can also be provided that the recesses are formed discreetly along the track, so that the molded body or bodies between the recesses extend in one piece up to the rail foot and are supported on the associated rail foot.

In particular, the recess for the molded body holder can be designed to fit precisely to the molded body holder in order to lock the respective molded body on the molded body holder along the track when the respective molded body is fixed to the rail.

The Fig. 1 , 2 and 3 show a partially built level crossing to cross a track. The track section comprises a pair of rails consisting of a first rail 2 and a second rail 2 ', which each have a rail foot 4, a rail head 6 and a rail web 8 connecting the rail head 6 and the rail foot 4 to one another. The two rails 2, 2 'are fastened to sleepers 14, in the present example concrete sleepers, with rail foot fastening screws 10 and rail foot fastening clips 12, for example Vossloh clips.

As in Fig. 1 shown, two similar plate-shaped intermediate rail molded bodies 20 are arranged between the two rails 2, 2 ', which are laid adjacent to one another alongside one another along the rails 2, 2'. The intermediate rail shaped bodies 20 extend transversely to the track from the first rail 2 to the second rail 2 'and essentially completely fill the gap between the two rails corresponding to the track width, although in the area of the rail heads 6 lane grooves 24 to accommodate the The traction wheel flanges remain. In this embodiment, the track grooves 24 are accordingly formed in the intermediate rail molding 20 as a fold or a hollow groove on the edge between the top and the narrow side 20a facing the rail. As in Figure 3b As can be seen, the intermediate rail shaped bodies 20 each come to rest on both rails 2, 2 'by resting on the rail feet 4 and touching the rail heads 6 in a linear fashion. The intermediate rail shaped bodies 20 are accordingly supported on the rail feet 4 of both rails 2, 2 '. The intermediate rail shaped bodies 20 themselves do not fill the rail chambers formed between the rail heads 6 and rail feet 4 on the side of the rail webs 8, so they do not come into contact with the rail web 8. As a result, the intermediate rail shaped bodies 20 can be inserted from above almost without deformation during installation and can also be easily removed upwards again during dismantling.

In the embodiment shown, the rail chambers are filled with chamber filling elements 22 that are precisely adapted to them. The intermediate rail shaped bodies 20 come with their narrow sides 20a facing the rails 2, 2 '(see FIG Fig. 4 ) on the respective chamber filling elements 20 to the plant.

The Fig. 2 also shows a first plate-shaped rail outer side molding 30 (in Fig. 1 not shown), which adjoins the outside 3 of the rail 2. In Fig. 1 and 3 a second plate-shaped rail outer side molding 32 is shown, which adjoins the outer side 3 'of the rail 2'. The rail outer side molded bodies 30, 32 come to rest on the respective rail 2 or 2 'in that they rest on the rail feet 4 (the cuts in Figures 3a and 3b not to be removed) and touch the rail heads 6 on the outside flat. The rail outer side molded bodies 30, 32 are accordingly supported on the rail foot 4 of the respective adjacent rail. Again, the rail chambers are not filled by the outer rail molded bodies 30, 32, but by chamber filling elements 22. In the example shown, the chamber filling elements 22 are identical parts for the inside and outside of the rails. However, different chamber filling elements can also be provided for this purpose.

Like the sectional view in Figure 3b can be seen, there are 8 cross bores 26 through the rail webs. In the example of Fig. 1 through the rail web 8 of each of the two rails 2, 2 'there are a plurality of transverse bores 26 which, with respect to the longitudinal direction of the rails, are arranged in a grid between the sleepers or rail foot fastening devices. In each of the rail webs 8 of the two rails 2, 2 ', the transverse bores 26 are located in the same positions in the track direction. Accordingly, the same number of transverse bores 26 for the level crossing are provided in each of the two rail webs 8.

Fastening screws 27 extend through the transverse bores 26 perpendicular to the direction of the rail. In the assembled state, the fastening screws 27 are in horizontal threaded inserts 28 (see also FIG Fig. 8 ) firmly screwed, which are incorporated on the narrow sides 20a within the intermediate rail shaped bodies 20 and thus face the inner sides of the rails 2, 2 '. As a result, the intermediate rail moldings 20 are each detachably but firmly screwed to both rails 2, 2 '. The intermediate rail shaped bodies are accordingly fastened to the rails 2, 2 'without play in the direction longitudinal to the rail, in the direction longitudinal to the perpendicular and in the direction transverse to the rail and transverse to the perpendicular. The intermediate rail shaped bodies 20 are accordingly fastened to the rails 2, 2 ′ by means of the fastening screws 27 and in particular not because they engage deeply in the rail chamber or reach far below the rail head 6. The Intermediate rail moldings are therefore also attached directly to the rails 2, 2 'and not merely indirectly by attachment to the sleepers.

In the illustrated embodiment, metallic holding blocks 40 (see also FIG Fig. 7 ) fastened with holding block transverse bores 41 and holding block longitudinal bores 42, in that the fastening screws 27 extend through the holding block transverse bores 41. The holding blocks 40 are braced horizontally across the rail against the chamber filling elements 22, which are arranged in the outer rail chambers of the rails 2, 2 '.

On the holding blocks 40, the rail outer side molded bodies 30, 32 can be locked indirectly on the fastening screws 27. For this purpose, securing rods 44 extend longitudinally along the track line through the holding block longitudinal bores 42, such as the Figure 3b can be found. The securing rods 44 also extend longitudinally along the track through longitudinal channels 34 (see also Fig. 5 ) the rail outer side molded body 30, 32, such as the Fig. 3a can be found. Referring to Fig. 3a Hollow tubes 36 are enclosed in the longitudinal channels 34 of the rail outer side molded bodies 30, 32 in order to ensure precise guidance of the securing rods 44. In this way, the shaped bodies 30, 32 on the outside of the rail are locked directly on the holding blocks 40. The shaped bodies 30, 32 on the outside of the rail are thus locked indirectly to the fastening screws 27 in a direction longitudinal to the perpendicular in order to secure the shaped bodies 30, 32 against being lifted out upwards. The outer rail molded bodies 30, 32 are thus also indirectly locked to the respective fastening means 27 in a direction transverse to the perpendicular and transverse to the track section in order to secure the molded bodies 30, 32 against horizontal removal away from the rail. In this example, the shaped bodies 30, 32 on the outside of the rail are not locked in a direction along the track by means of the securing rods 44.

As in Figure 3b As can be seen, the transverse bores 26 run in relation to the height of the rail 2 'in the lower region of the rail web 8. In the exemplary embodiment shown, the result is that the securing rods 44 and thus also the longitudinal channels 34 of the molded bodies 30, 32 are spaced from the lower and lower ends the top of the molded bodies 30, 32, preferably in the middle third with respect to the height of the molded bodies 30, 32 and thus there is still enough molded body material underneath to ensure the required stability. In the exemplary embodiment shown, the securing rods 44 run above the fastening screws 27 extending through the transverse bores 44.

However, other designs are also possible. For example, the transverse bores 26 can also extend through the middle or upper region of the rail webs 8 and the securing rods 44 below the fastening screws 27. In this case, locking of the outer side moldings 30, 32 on the fastening screws 27 could also be done directly, ie without one Holding block 40, are made possible, for example by the securing rods 44 reaching under and / or reaching behind the screw head.

The in Fig. 1 The partially constructed level crossing shown is constructed by first drilling a plurality of transverse bores 26 regularly spaced apart in the longitudinal direction of the rail through the rail web 8 of each of the two rails 2, 2 '. The positions of the transverse bores 26 on the rail webs 8 are preferably marked on the rail webs 8 by means of a special drilling template (not shown) before drilling. Subsequently, the chamber filling elements 22 are mounted on the inner and outer sides of the rails 2, 2 ′, the transverse channels 220 being congruent with the transverse bores 26.

In the next step, the intermediate rail moldings 20 (of the third group) are placed between the two rails 2, 2 ', for example by lifting them up at the openings 23 with ropes or the like and lowering them between the rails 2, 2'. The intermediate rail shaped bodies 20 are placed between the rails 2, 2 'in such a way that the threaded inserts 28 located on their narrow sides 20a coincide with the transverse bores 26 and that the two shaped bodies 20 are adjacent to one another along the rails 2, 2'.

The procedure for each of the transverse bores 26 is as follows: a holding block 40 is placed on the outer chamber filling element 22 so that its holding block transverse bore 41 coincides with the transverse channel 220 of the chamber filling element 22. Then the respective fastening screw 27 is inserted through the holding block transverse bore 41, through the transverse channel 220 of the outer chamber filling element, through the transverse bore 26 in the rail web 8 and through the transverse channel 220 of the inner chamber filling element into the threaded insert 28 of the intermediate rail molding 20 and tightened tightened in order to screw the intermediate rail shaped body tight and at the same time to brace the holding block 40 on the outer chamber filling element.

In the next step, similar outer side moldings 32 (of the second group) are placed adjacent to the outside of the second rail 2 ', so that the moldings 32 are adjacent to one another along the rails 2' and the in The longitudinal channel 34 of the rail 2 'facing these molded bodies and runs longitudinally along the rail 2' (in Fig. 1 only one shaped body 32 is shown). The rail outer side molded bodies 32 are then locked against a movement longitudinally to the perpendicular and against a movement transversely to the perpendicular and transversely to the rail 2 'by securing rods 44 in the longitudinal channel 34 of the two molded bodies 32 along the track and in the holding block longitudinal bores 42 of the two associated retaining blocks 40 are inserted into engagement. A plurality of securing rods 44 with a length shorter than the width of the level crossing can be inserted one after the other into the longitudinal channel 34 of a shaped body at the edge, each of which pushes the previously introduced securing rods further into the longitudinal channel 34. As a result, the two rail outer shaped bodies 32 are secured against being lifted out upwards and against horizontal removal away from the rail 2 ′.

Finally, similar outer side moldings 30 (of the first group) are placed adjacent to the outer side of the first rail 2 (in FIG Fig. 2 shown) and locked, so that the first, third and second group of shaped bodies in a two-dimensional grid form a flat traffic area approximately at the level of the running surfaces of the rails 2, 2 'across the rails 2, 2'. The width of the traffic area corresponds to the width of the groups of shaped bodies lying next to one another in the direction of the track.

A built level crossing can also be easily removed again. In the illustrated embodiment of FIGS. 1 to 3 For this purpose, the rail outer side molded bodies 30, 32 are unlocked by removing the securing rods 44. Then the molded bodies 30, 32 can be removed from the track. The detachably fastened intermediate rail shaped bodies 20 can then be loosened by unscrewing the fastening screws 27 and removed from the track. The possibility of being able to expand the level crossing is advantageous in order to replace parts of the level crossing, for example individual moldings, or to carry out maintenance work on the track bed in the area of the level crossing, in particular to plug the track bed. After such work, the level crossing can then be rebuilt, the transverse bores 26 already present in the rail webs 8 being reused.

As in Fig. 4 designated, the intermediate rail molded body 20 has two narrow sides 20a which face the rails 2, 2 'when the molded body is installed. The shaped body also has two end faces 20b which adjoin adjacent shaped bodies when the shaped body is installed. The molded body 20 has recesses on its underside 29, which are slipped over the rail foot fastening devices from above during installation (see also Fig. 3a ).

The recesses do not extend continuously along the width of the shaped body 20, i.e. along the rail when installed. In the installed state, the molded body 20 accordingly extends in one piece between the recesses up to the rail foot 4 and is supported thereon.

In each of the narrow sides 20a facing the rail there is a horizontal receiving device 21, in particular designed as a channel, for a fastening means 27 and / or a threaded insert. In particular in the case of rubber-elastic molded bodies, threaded inserts are already set in the receiving devices 21 at the factory. The threaded inserts can, for example, be screwed into the receiving devices 21 or already molded into the molded bodies during manufacture (see also FIG Figure 3b ).

The width of a molded body corresponds to the distance between the two end faces 20b. Openings 23 can extend through the width of the intermediate rail shaped body 20, to which the shaped body 20 can be attached, for example, with ropes or chains, in order to lift it. A hollow tube 25 can be enclosed within the openings 23, as shown in FIG Figure 3b can be seen. Advantageously, the molded body 20 is protected from damage when it is lifted with a rope or a chain, and the molded body also has increased stability, which increases its load-bearing capacity, for example when driving on a heavy truck.

As in Fig. 5 designated, the rail outer side molded body 30 has two narrow sides 30c and 30a, the narrow side 30a facing the respective rail 2 or 2 'when the molded body is installed. The molded body also has two end faces 30b which adjoin adjacent molded bodies when the molded body is installed.

The molded body 30 has on its underside recesses 39 for the rail foot fastening devices and a recess 37 for the holding block 40 and the fastening screw 27 (see also FIG Figures 3a and 3b ). The recess 37 is dimensioned in accordance with the holding block 40 and the fastening screw 27. In the track direction, the recess 37 is designed to fit the holding block 40 precisely. As a result, the molded body 30 on the outside of the rail is locked in the installed state along the length of the track.

Furthermore, a longitudinal channel 34 extends through the rail outer side molded body 30, into which the securing rod 44 is inserted in order to lock the rail outer side molded body 30 on the holding block 40.

Fig. 6 illustrates a chamber filling element 22 which is provided for both the outer and the inner rail chamber of a Vignole rail 2 or 2 '. The chamber filling element 22 is inserted into the rail chamber with its rounded side 22a facing the rail.

The side 22c facing away from the rail is essentially straight and faces the respective intermediate rail shaped body 20 or rail outer shaped body 30 or 32. The side 22c of a built-in chamber filling element 22 facing away from the rail runs essentially flush with the side surface of the rail head 6. The side 22c facing away from the rail also has recesses 221 for the holding blocks 40.

If more than one chamber filling element is used for a rail chamber, their end faces 22b butt against one another in order to form a continuous path.

In the present example, the chamber filling element 22 shown is longer than the shaped bodies are wide and, in particular, has a length which corresponds to the width of two shaped bodies 20 arranged alongside one another along the rail. Accordingly, the chamber filling element 22 has several, here two transverse channels 220 for fastening screws 27.

Fig. 7 shows a cuboid holding block 40 which has a holding block transverse bore 41 for the fastening screw 27 and a holding block longitudinal bore 42 orthogonal thereto for a securing rod 44. The holding block transverse bore 41 runs through the side surfaces 40b and parallel to the side surfaces 40a and 40c, while the holding block longitudinal bore 42 runs through the side surfaces 40a and parallel to the side surfaces 40b and 40c.

Like that Figures 7b and 7c It can be seen that the two bores 41 and 42 are spaced apart from one another along the normal to the side surfaces 40c, that is to say not coplanar. The two bores 41 and 42 are accordingly offset from one another, so that both bores can be penetrated by a fastening screw 27 or a securing rod 44 at the same time.

A holding block 40 designed as a parallelepiped with two plane-parallel and, in the assembled state, perpendicular side surfaces 40a is particularly advantageous, since a rail outer side molded body 30 with a parallelepiped recess 37 for mounting can be passed at the top of the holding block 40 and is finally locked in the installed state with the corresponding inner sides of the recess 37 on the holding block 40 in both directions along the rail. The recess 37 of the rail outer side molded body 37 is accordingly formed in the longitudinal direction to the rail with an exact fit to the length of the holding block 40 defined by the distance between the two side surfaces 40a.

Fig. 8 FIG. 11 shows a threaded insert 28. Referring to FIG Figure 3b a threaded insert 28 is already molded into the rubber-elastic intermediate rail molding 20 at the factory.

The threaded insert 28 has an internal thread 280 into which the fastening screw 27 is screwed. Furthermore, the threaded insert 28 has a threaded sleeve 281 and an anchor element 282, which in this example is designed in the form of a transverse rod. The anchor element 282 holds the threaded insert 28 in the molded body when the fastening screw 27 is tightened and at the same time prevents rotation of the threaded insert 28 in the molded body.

The Figures 9-14 relate to a further embodiment of a level crossing. As in Fig. 9 and 10 shown, the level crossing again leads over a track with two rails 2, 2 'attached to sleepers 14.

In this embodiment, the rail chambers are on the inside and outside 3, 3 'of the rails with different chamber filling elements 22' and 22 "(see also FIG Fig. 13 ) filled out. In particular, the chamber filling elements 22 'on the flange side for the inside of the rails are wider than the rail chamber and thus protrude horizontally from the rail chamber.

As in the embodiment of Fig. 1 are arranged on the rails 2, 2 'intermediate rail molded bodies 20' and rail outer side molded bodies 30 ', 32' which adjoin the chamber filling elements. In contrast to the embodiment in Fig. 1 the intermediate rail shaped bodies 20 ', which adjoin the chamber filling elements 22' on the flange side, are spaced apart from the rails 2, 2 'over their entire height. The track groove 24 is accordingly formed in this embodiment by the free space running next to the rail head 6 above the chamber filling element 22 'on the inside of the rail. The intermediate rail shaped body 20 ′ accordingly neither touches the rail heads nor does it intervene in the rail chamber.

As in Fig. 10 can be seen, transverse bores 26 are again provided through the rail webs 8 of the rails 2, 2 '. Through the transverse bores 26, fastening screws 27 are in Receiving devices 21 'of the intermediate rail shaped bodies 20' are screwed. It is preferably provided to insert threaded inserts into the receiving devices 21 '.

In this exemplary embodiment, in the installed state, L-shaped mounting brackets 50 (see also FIG Fig. 14 ) braced against the chamber filling elements 22 ″ on the outside of the rail by means of holes 51 in the leg 50a of the bracket 50. The molded bodies 30 ', 32' on the outside of the rail are fastened indirectly to the fastening screws 27 by means of the bracket 50. For this purpose, the molded bodies 30 ', 32' on the outside of the rail have Vertical bores 35 in order to screw these molded bodies from above through the vertical bores 35 in the holes 52 of the legs 50b of the mounting brackets 50. In this way, the rail outer side molded bodies 30 ', 32' are directly on the mounting brackets 50 and indirectly on the fastening screws 27 In contrast to the embodiment of the Fig. 1 the outer side of the rail molded bodies 30 ', 32' are thus fastened to the rails 2, 2 'without play by the holding means in all directions, ie in the direction along the rail, in the direction along the perpendicular and in the direction transverse to the rail and transversely to the perpendicular .

Referring to Fig. 11 the intermediate rail shaped body 20 'has two narrow sides 20a' and two end faces 20b '. The narrow sides 20a 'face the rails 2, 2' when the molded body 20 'is installed. The end faces 20b 'can adjoin other molded bodies 20' if the level crossing comprises several molded bodies in the longitudinal direction of the rails. On the underside of the molded body 20 'there are recesses 29' for the rail foot fastening devices. In each of the narrow sides 20a 'there is a receiving device 21' for a fastening screw 27. As in the exemplary embodiment of FIG Fig. 1 It can be provided that a threaded insert or a dowel is molded or mounted in the receiving devices 21 '.

Referring to Fig. 12 if the rail outer side molded body 32 'has two narrow sides 32c' and 32a ', the narrow side 32a' facing the respective rail 2 or 2 'when the molded body is installed. The shaped body furthermore has two end faces 32b 'which adjoin or rest on adjacent shaped bodies when the shaped body is installed. On its underside, the molded body 32 'has recesses 39' for the rail foot fastening devices.

Furthermore, one or more vertical bores 35, in the example shown four pieces, extend through the rail outer side molded body 32 ′ in order to screw the molded body onto the bracket 50.

Fig. 13 illustrates two chamber filling elements 22 'and 22 "which are provided for the rail chambers on the inner and outer sides 3, 3' of the rails 2, 2 '. In this exemplary embodiment, the chamber filling elements 22', 22" have a length that is the width of the corresponds to adjoining shaped body. Accordingly, the chamber filling elements 22 ', 22 "each have only one transverse channel 220' or 220" through which the fastening screws 27 can extend.

As can be seen in this example, the rail-facing sides 22a ', 22a "of the chamber filling elements 22', 22" can be rounded, in particular precisely fitting the rail chamber, or polygonally approximated to the shape of the rail chamber. The sides 22c ′, 22c ″ facing away from the rail face the respective intermediate rail shaped bodies or rail outer shaped bodies and are essentially straight in both cases.

The chamber filling element 22 ′ for the inner sides of the rails is designed so wide that it protrudes sufficiently far from the rail chamber to form the track groove 24 next to the rail head 6. Because of its greater width, the chamber filling element 22 'also has recesses 229 for the rail foot fastening devices.

Referring to Fig. 14 the bracket 50 each have a leg 50a with a hole 51 in order to fasten the bracket 50 under the screw head of the fastening screw 27. One or more, for example four, holes 52 are located in a leg 50b in order to screw the rail outer side molded bodies 30 ′, 32 ′ through the vertical bores 35 to the holding brackets 50.

Referring to Fig. 15 it can be provided that groups of similar shaped bodies are installed along the track direction. Shown are a first and second group of similar rail outer side moldings 30 and 32 and a third group of similar intermediate rail moldings 20. A built-up level crossing can accordingly comprise a plurality of molded bodies in the track direction so that the width of the level crossing corresponds to the width of the traffic area 60, 60 'that crosses the track is adapted. In the example of Fig. 15 Eight molded bodies per group are included, which directly abut one another in the direction of the track. The outer rail shaped bodies 30 of the first group, the intermediate rail shaped bodies 20 of the third group and the outer rail shaped bodies 32 of the second group thus form the traffic area of the level crossing across the rails in a two-dimensional grid.

Transverse to the track direction, a track designed as a pair of rails can accordingly be made passable by three plates, namely a first outer rail molding 30 adjoining the traffic area 60, an intermediate rail molding 20 and a second outer rail molding 32 adjoining the traffic area 60.

The shaped bodies 30, 32 on the outside of the rail are connected to the asphalt of the traffic area 60 crossing the track section, in particular on their narrow side facing away from the rail. The surface of the level crossing formed by the shaped bodies is essentially at the same height as the surface of the crossing traffic area 60, so that the road users can easily pass the level crossing.

Referring to Fig. 1 are the in Fig. 15 The intermediate rail shaped body 20 shown is fastened with two fastening screws 27 through corresponding transverse bores 26. There is accordingly a transverse bore in each rail web 8 of the two rails 2 and 2 'for each intermediate rail shaped body 20.

Referring to Fig. 5 assign the in Fig. 15 The rail outer side molded bodies 30 of the first group shown and the rail outer side molded bodies 32 of the second group have the same longitudinal channel 34. In the installed state, a securing rod 44, the length of which is adapted to the width of the level crossing, can thus extend through the longitudinal channels 34 of the molded body group. However, it can also be provided that several, in particular similar securing rods 44, which are shorter than the width of the level crossing, extend through the longitudinal channels 34. The particular advantage of using several shorter safety rods is that the rods can be transported and installed more easily.

The outer side of the rail molded bodies 30 are not clamped to one another along the rail, but are each locked independently with their recesses 37 on the holding blocks 40 to prevent displacement along the rail. The same applies to the rail outer side molded bodies 32. The intermediate rail molded bodies 20 are also not braced with one another, but instead are each fastened independently to the rails 2, 2 'with fastening screws 27.

Referring to Fig. 16 , 17th and 19th For example, the holding blocks 40 may comprise a spacer web 43 which rests on the rail web 8 and which acts as a spacer. On In this way, it is possible to prevent the chamber filling elements 22 on which the holding brackets 40 are placed from compressing and deforming when the fastening screws are tightened. This also ensures that the longitudinal bores 42 in the holding blocks 40 have a defined distance from the rail 2 '. This is particularly advantageous so that the inner diameter of the hollow tubes 36 enclosed in the rail outer molded bodies 32 precisely coincide with the longitudinal bores 42 in the holding blocks 40 so that the securing rods 44 can be inserted without problems.

Because the curves of the rail chamber can be different, a narrow spacer web 43 on a holding block 40 is particularly suitable. In this way, the spacer web 43 rests only with a small area and approximately centrally with respect to the height of the rail on the essentially straight center piece of the rail web 8.

Referring to Fig. 16 , 18th and 19th In this case, chamber filling elements 22 ′ ″ are used which have recesses 223 for the spacer webs 43 of the holding blocks 40 and the fastening screws 27. Alternatively, it is possible that the chamber filling elements have slots and transverse channels for the fastening screws adapted to the spacer webs 43.

Referring to Fig. 20 It can be provided that the surfaces of the molded bodies, which form the traffic area across the level crossing, are designed to be slip-reducing in order to ensure safe driving and entering of the level crossing, especially when it is wet. According to the in Fig. 20 A grooved surface 70c can be provided for this purpose in relation to its outer shape, which is only shown schematically in the form of the molded body 70. The hatching in the surface 70c here indicates a diamond-like corrugation. Furthermore, the slip resistance of the surfaces of the shaped bodies serving as traffic areas can be increased by texturing the surfaces with mineral mixtures, corundum, sand or the like.

Referring to Fig. 21 Intermediate rail moldings 20 or rail outer side moldings 30, 32 can each be designed as base plate moldings 18, with cover plate moldings 19 resting on the base plate moldings 18. In this vertically two-part configuration, in particular the lower base plate molded bodies 18 can be fixed or locked in accordance with the above statements with fastening screws 27, holding blocks 40 and securing rods 44.

The Fig. 22 and 23 show a further type of fixation using the example of the vertically two-part configuration, but without limitation to this configuration. The baseplate moldings 18, or the intermediate rail shaped bodies 20, 20 'and / or the rail outer side shaped bodies 30, 32, 30', 32 ', in the case of the embodiment according to FIG Fig. 1 or 9 , hereinafter generally referred to as molded bodies, are fixed to the respective rail or rails 2, 2 ′ by means of molded body holders 80. A molded body holder 80 is attached directly to a rail. A transverse drilling through the rail web 8 is therefore not necessary in this case.

The molded bodies, which each adjoin one of the outer sides of the two rails 2, 2 ', are each fixed to a rail by means of a molded body holder 80, while the molded body, which is located between the two rails 2, 2', is attached to both rails 2 , 2 'is fixed by means of a respective molded body holder 80. It is therefore not necessary for the molded bodies to engage in the rail chamber. Fixing a shaped body on the rail 2, 2 'by means of a shaped body holder 80 or by means of a transverse bore 26 (as described above) is more secure and stable than fixing by engaging the shaped body in the rail chamber and also facilitates assembly because the shaped body does not need to be threaded into the rail chamber.

In order to build a railroad crossing with a sufficient width, a plurality of shaped bodies are generally arranged next to one another along the track, with three groups of shaped bodies often being laid, as already described above. A plurality of shaped body holders 80 can then be fastened at a regular distance along the respective rail 2, 2 'in order to fix the groups of shaped bodies thereon. The shaped body holders 80 on one rail 2 are expediently located at the same positions along the track direction as the shaped body holders 80 on the other rail 2 '.

In the figures shown, at least one shaped body holder 80 is provided for each shaped body. However, a plurality of shaped bodies (i.e. shaped bodies of a group) arranged next to one another in the track direction can also be fixed together on a shaped body holder 80. This can be particularly advantageous in order to reduce the number of shaped body holders 80.

The preferably metallic molded body holders 80 can be retrofitted to an existing track grid with sleepers 14 and rails 2, 2 'attached to them in order to erect a level crossing over the track grid. As shown, the molded body holders 80 are preferably fastened between the sleepers 14 or between the rail foot fastening devices 10, 12 on the rails 2, 2 '. This allows the molded bodies are fixed directly to the rails 2, 2 'by means of the molded body holder 80. This enables a particularly secure and stable fixation of the shaped bodies on the track grid, especially in the area near the rails.

A shaped body can be locked on a shaped body holder 80 in a corresponding manner, as described above in connection with a holding block 40. The above statements accordingly apply analogously to the molded body holder 80.

A molded body can accordingly be locked on the associated molded body holder 80 with a securing rod 44 and thus secured against being lifted upwards and against being removed from the rail to the side. In the locked state, the securing rod 44 extends longitudinally along the track through a longitudinal bore 42 'in the molded body holder 80. The securing rod 44 also extends longitudinally along the track through a longitudinal channel in the molded body, so that the molded body on the molded body holder 80 is fixed.

Referring to Fig. 24 , 25 and 26 the molded body holder 80 is designed as a clamp which can be clamped to the rail. In this example, a molded body holder 80 has two holding jaws 82, 82 ', which are symmetrical in the example shown. The two holding jaws 82, 82 'designed as holding clamps each clamp around the rail foot 4 and are arranged opposite one another on both sides of the rail 2'.

The holding jaws 82, 82 'each have a rail foot grip section 84, 84' which rests on the underside of the rail foot 4. The holding jaws 82, 82 ′ of a molded body holder 80 can be clamped together by means of a clamping screw 86. For this purpose, the holding jaws 82, 82 'each have a clamping screw guide 88, 88', the clamping screw 86 extending jointly through the clamping screw guides 88, 88 'of both holding jaws 82, 82'. The tensioning screw guides 88, 88 'and the tensioning screw 86 run below the rail foot 4. In the example shown, the tensioning screw guides 88, 88' are therefore each arranged on the rail foot under-grip section 84, 84 '. The clamping screw 86 has two threaded ends 86a and 86b, onto each of which a clamping nut 90, 90 ′ is screwed in order to clamp the holding jaws 82, 82 ′ with one another and against the rail foot 4. In the clamped state, the rail foot 4 is accordingly clamped between the two holding jaws 82, 82 'of a molded body holder 80, similar to a screw clamp.

In a further embodiment, not shown, the opposing holding jaws 82, 82 ′ of a molded body holder 80 can also be clamped together and on the rail through a transverse bore 26. According to the same principle, two holding blocks 40 can also be screwed in opposition to one another on a rail through a transverse bore 26.

For all embodiments it is preferably provided that a molded body, for example an intermediate rail molded body 20, 20 ', a rail outside molded body 30, 32, 30', 32 ', a base plate molded body 18 or a cover plate molded body 19, have a certain minimum thickness has in the vertical direction based on the installed state. This ensures sufficient stability of the level crossing or of the individual molded bodies, in particular in the case of molded bodies made of rubber-elastic material, in particular bonded rubber granulate or vulcanized rubber. A shaped body accordingly has a thickness, at least in the major part of its horizontal extension, which corresponds to at least half, preferably at least the entire height of the rail head, e.g. at least 25 mm or at least 50 mm. In particular, the molded body (s) 20, 20 ', 30, 32, 30', 32 ', 18, 19 does not just consist of a thin, rigid metal plate with fuse blocks flanged on the sides.

Fig. 27 shows a level crossing with lower base plate molded bodies 18 and cover plate molded bodies 19 arranged above. While the base plate molded bodies 18 rest at least partially on the sleepers 14 and on the rail feet 4 and form a load-bearing part of the traffic area of the level crossing, the upper cover plate- Shaped body 19 up to the level of the running surfaces of the rails 2, 2 'and form the surface of the traffic area of the level crossing. Advantages of this vertically two-part design are that the upper cover plates can be exchanged relatively easily, especially if only the surface of the traffic area needs to be renewed, and that the cover plates and the base plates can each be manufactured with significantly lower and thus practically more manageable weights. This makes it possible, in particular, that the moldings can be laid by construction workers without using a construction machine.

Both the cover plate molded bodies 19 and the base plate molded bodies 18 consist of an elastomer or an elastomer mixture and preferably each have a mass of less than 100 kg, preferably less than 90 kg, particularly preferably less than 85 kg.

The base plate shaped bodies 18 have an extension in the track direction which corresponds to the sleeper spacing, so that they can each rest next to one another along the track direction on two adjacent sleepers 14. The baseplate molded bodies 18 are thus arranged in the track direction according to a baseplate grid that is defined by the sleeper spacing. In contrast, the cover plate molded bodies 19 can be arranged according to a different or offset cover plate grid in the track direction. In the example shown, the cover plate moldings 19 are each offset with respect to the base plate moldings, the cover plate grid being offset by half a threshold distance from the base plate grid for the moldings located between the rails. In general, the grid spacing can also differ, in this example the outer-side cover plate moldings 19 have different dimensions in the track direction than the base plate moldings 18. While an offset of the cover plates with respect to the base plates, i.e. an offset of the end-face joints, the stability of the level crossing increased, the flexible cover plate grid can be used to dimension the weights of the moldings as desired.

The baseplate molded bodies 18 are each directly detachably but firmly fixed to the rails 2, 2 ', whereby more generally provision can also be made for the baseplate molded bodies 18 to be detachably but firmly connected, in particular screwed, to the track grid. In contrast, the cover plate molded bodies 19 are clamped under the rail heads 6. However, the cover plate molded bodies 19 are detachably but firmly connected to the underlying base plate molded bodies 18, i.e. fixed to them, preferably by screwing.

Referring to the Figures 28 and 29 the upper cover plate molded bodies 19 have track grooves 24 and an edge bead 80 which engages under the rail head 6 in the rail chamber and at least partially fills it. Apart from the track grooves 24 in the area close to the rails, the cover plate molded bodies 19 are flat, in particular designed without further grooves. The surface of the cover plate molded bodies 19 that can be driven or walked on can, however, be designed to be rough or structured in order to reduce the risk of slipping.

The baseplate molded bodies 18, cover plate molded bodies 19 laid between the rails 2, 2 'extend transversely to the track section from the first rail 2 to the second rail 2' and those adjacent to one of the outer sides of one of the two rails Base plate and cover plate molded bodies 18, 19 extend from the respective rail to the adjoining traffic area, not shown here.

The lower baseplate molded bodies 18 each rest on the rail foot 4 of the respective rail 2, 2 'and are supported thereon, with recesses 29 ″, 39 ″ for the rail foot fastening devices 10, 12 (see FIG Fig. 27 ) and recesses 37 ″ are provided for the molded body holder 80 or (when fixed by means of transverse bores 26) for holding means 40 and / or fastening means 27. In this example, the recesses are not continuous but rather discreetly formed along the track direction and can each be designed with an accurate fit so that the molded bodies are thereby locked longitudinally along the track direction.

The baseplate molded bodies 18 arranged between the rails preferably do not engage in the rail chamber and do not fill the rail chamber, so that the baseplate molded body 18 arranged between the rails can be lowered vertically from above down to the rail foot 4 during installation without getting into the rail chamber to be threaded. Rather, the rail chambers on the inside of the rails 2, 2 are filled with chamber filling elements 22 '' ''. In contrast, the baseplate molded bodies 18 adjoining the outer sides of the rails engage in the rail chamber and fill it, because these molded bodies can usually be inserted laterally into the rail chamber before the connection to the adjacent traffic area is established. Chamber filling elements on the outside of the rails can thus be dispensed with. This can analogously also be provided for the vertically one-piece configuration of intermediate rail molded bodies 20 or rail outer side molded bodies 30, 32.

The cover plate molded bodies 19 can be screwed to the base plate molded bodies 18 by means of screws 102, the screws 102 only being shown here for the outer molded bodies. For example, four screws can be provided for the cover plates between the rails and two screws for the outer cover plates.

Referring to Figures 30 and 31 two possibilities are illustrated to ensure a tolerance in the track direction for the screw connection. On the one hand, elongated holes 106 can be made in the cover plates. Screws 102 can then be screwed into threaded inserts 104 in the base plates through the elongated holes 106. On the other hand, C-rail inserts 108 can be installed in the base plates along the track direction be brought in. Screws 102 can then be screwed into the C-rail inserts 108, for example through round holes 107 in the cover plates. The screw connection of the cover plates to the base plates ensures, in particular, a vertical fixation of the cover plates.

In order to further improve the horizontal fixing of the cover plate molded bodies 19 with respect to the base plate molded bodies 18, a form-fitting interlocking of a molded body projection 110 in a molded body recess 112 is expedient. In the example shown, the cover plate molded bodies 19 have positive projections 110, which can be found as negative recesses 112 in the base plate molded bodies 18. The shaped body projections 110 and shaped body recesses 112 are preferably designed in such a way that the cover plates are locked both along and across the track.
