Description

Device for fixing the position of moldings of a track transition device on a track system

description

The present invention relates to a device for fixing the position of shaped bodies of a track transition device on a track system, the track transition device having a plurality of shaped bodies which follow one another in a longitudinal direction of the track system, preferably abutting one another.

DE-42 29 289-A discloses a track transition device formed from molded articles. The track transition device comprises a plurality of central shaped bodies which are arranged in succession between the two rails of a track system and are each formed in their end regions close to the rails in such a way that they engage under the rail heads. Outside moldings are arranged on the outside of the two rails, which also engage under the rail heads with their end regions near the rails. The molded bodies each have grooves or tongues in mutually facing end faces. When arranged between or outside the rails, the molded bodies with the grooves or tongues engage in a form-fitting manner in one another on their end faces which are brought into contact with one another. Both the central molded body and the outer molded body are made of plastic material, in particular rubber material.

To fix the position of such shaped bodies on the track system, it is known to screw end angles or package angles to sleepers of the track system. The end brackets are each attached in such a way that they engage on the outer end faces of the last shaped body in the longitudinal direction of the track system. The package angles are arranged in intermediate areas and fen with respective shaped bodies to form individual packages of shaped bodies fixed in their position. For example, packages with a length of approximately 6 m are formed. In order to prevent gaps from forming between the individual moldings when the track transition device constructed in this way is stressed, the moldings made of plastic must lie against one another with a sufficiently large prestress. It has been shown, however, that if the molded bodies are subjected to continued stress, this prestress is lost relatively quickly and, in particular in the case of longer track transition devices, relatively large gaps can form between the molded bodies. In addition, the external dimensions of these moldings are dependent on the outside temperature, and when the temperatures decrease, the moldings made of plastic shrink, so that additional preload is lost and the shrinkage of individual moldings can add up over the length of the track transition device and thus relative solely due to the cold shrinkage large gaps can arise. However, since the end angles or package angles are screwed to the sleepers to fix the position, the entire track transition device must be dismantled to correct gaps that arise during operation, i.e. the moldings must be removed and the position of the package angles or end angles must be screwed to the sleepers again Getting corrected.

In addition, there is the problem with this known type of position fixation for the shaped bodies that the package angles produce a direct coupling between the shaped body and the threshold. If the track transition device is then particularly stressed in a direction which is at an angle of less than 90 ° to the longitudinal direction of the track system, for example due to driving on heavy trucks, then due to the relatively large force acting on the moldings and the package angles acting on them, Force is applied to the sleepers, which can lead to a shift in the sleepers. From DE 28 03 021 AI a track transition device is known in which a plurality of molded bodies arranged in succession in the longitudinal direction of the track transition device are combined to form a structural unit by fixing rods also extending in the longitudinal direction. The fixing rods extend through all molded bodies arranged one on top of the other, and clamping nuts are provided at the ends of the fixing rods opposite in the longitudinal direction, which can be screwed onto the fixing rods in the direction of the molded bodies, in order to thereby clamp the molded bodies against one another. Furthermore, the fixing rods are coupled to plates in the end regions, that is to say clamped between plates which are screwed to sleepers located in end regions of the track transition device. Also with this known track crossing device there is the problem that on the one hand the moldings have to be pretensioned against one another with very high force in order to prevent gaps, but on the other hand when shifting obliquely with heavy trucks and at least in the case of longer track crossing devices the displacement of lying in the region of the longitudinal center of the level crossing Shaped bodies can not be avoided.

In contrast, it is the object of the present invention to provide a device for position fixing of mold bodies in a track transition device on a track system, with which the formation of gaps between the shaped bodies can be avoided with simple assembly.

According to the invention, this object is achieved by a device for fixing the position of shaped bodies of a track transition device on a track system, the track transition device comprising a plurality of shaped bodies which follow one another in a longitudinal direction of the track system, preferably abutting one another, the device comprising: at least one fixing rod means extending in the longitudinal direction of the track system along the shaped bodies, wherein at least some of the shaped bodies can be coupled or coupled together to form a structural unit by the at least one fixing rod means, end contact means which are located on or near each of the end regions of the at least one opposite in the longitudinal direction of the track system Fixing rod means are firmly coupled or firmly coupled and can be brought to rest on a respective end face of the last shaped body in the longitudinal direction of the structural unit.

According to the invention, at least one intermediate contact means is also provided, which can be firmly coupled or firmly coupled to the at least one fixing rod means in an intermediate region arranged between the end regions and can be brought to bear against a contact surface provided on at least one of the molded bodies essentially in the longitudinal direction of the track system .

With the device according to the invention, it is therefore possible, by coupling the fixing rod means via the end contact means and the at least one intermediate contact means with the shaped bodies, to provide the track transition device as a coupled structural unit. The essential principle here is that the at least one intermediate attachment means, possibly in cooperation with the end attachment means, forms packages or groups which are combined by the fixing rod means to form a coherent structural unit. The action of force, for example when trucks drive onto a track transition device fixed in position with a device according to the invention, cannot lead to the displacement of individual moldings, but rather is transferred to the fixing rod means. Since both the end contact means and the at least one intermediate contact means are not attached to the track system, but instead provide a fixation of the position of the individual moldings by means of the fixing rod means, If, for example, oblique force is exerted, a force cannot be exerted, for example, on sleepers of the track system, which leads to a displacement of the sleepers or the like. It should be pointed out here that although different terms have been chosen for the final investment means and the at least one intermediate investment means, these respective investment means, ie final investment means and intermediate investment means, can be formed by identical components.

To enable the position of the entire track transition device to be fixed, it is proposed that at least one fastening means be provided for fixing the fixing rod means and / or the structural unit with respect to the track system. Although after assembling a track transition device with the device according to the invention, a displacement of the entire track transition device due to the coupling of the moldings by the device according to the invention to an entire structural unit is almost impossible, the fastening means in this state can also contribute to fixing the position of the entire track transition device.

In order to be able to provide track transition devices of any length, it is proposed that the at least one fixing rod means comprise a plurality of threaded rod elements which are arranged in succession in the longitudinal direction of the track system, wherein directly successive threaded rod elements can be connected to one another by screw connection means.

For example, it can be provided that the at least one fixing rod means for each molded body or each molded body group of the structural unit comprises at least one fixing rod piece which has an external thread section in a first end region thereof as a first connecting section and an internal thread opening in a second end region thereof as a second connecting section - has. With such a construction, identical fixing rod pieces can be used for a large number of shaped bodies, so that the number of differently designed components in the device according to the invention is kept low.

To construct a track transition device according to the invention by means of the fixing rod pieces, it can be provided that the external thread section of a fixing rod piece assigned to a molded body or a molded body group can be brought into connection engagement with the internal thread opening of a fixing rod piece which is assigned to a molded body or molded body group immediately following in the longitudinal direction .

The assembly process can be carried out in a simple manner if the at least one fixing rod piece carries an intermediate contact means near one of its end regions, preferably the second end region. Such a design of the fixing rod pieces ensures that a fixed point is subsequently created for each molded body or each molded body group, at which forces acting on the molded bodies are introduced into the fixing rod means and are not passed on to immediately following molded bodies.

In order to be able to use the device according to the invention to construct a track transition device in the longitudinal direction in both directions in the same way, the present invention furthermore comprises an intermediate piece with a connection area for connection with two identical connection sections, preferably the two first connection sections, of two directly following one another in the longitudinal direction and fixing rod pieces to be connected together.

For example, the intermediate piece can be designed such that it has an internal thread opening in its connecting area for each first connecting section of the two fixing rod pieces. In order to be able to provide a fixed point for the introduction of force from the shaped bodies into the fixing rod means also in the area of the arrangement of an intermediate piece, it is further proposed that the intermediate piece carries an intermediate contact element. In an advantageous embodiment it can be provided that the contact surfaces of the shaped bodies are formed on mutually opposite end faces of directly adjacent shaped bodies and that a recess for receiving the at least one intermediate contact means is formed in at least one of the opposite end faces of two immediately adjacent shaped bodies. By providing the recess, the end faces of the shaped bodies can be brought into contact with one another without this contact condition being impaired by the intermediate contact means.

It can be provided that when the at least one intermediate contact means is arranged in the recess, a predetermined distance is provided between a surface which delimits the recess at the top and an upper edge of the at least one intermediate contact means. It can thus be avoided that when the molded body is subjected to pressure in the area above the at least one intermediate attachment means, for example by driving on a truck, the surface which delimits the recess upwards is pressed against the upper edge of the at least one intermediate attachment means and thereby possibly damage the Shaped body is caused in this area.

In order to prevent that when a track system on which a track transition device is provided a coupling part hanging down from a train gets caught on a molded body when it hits the track transition device or causes damage to the track transition device, it is proposed that coupling deflector means be provided are, each on the in the longitudinal direction of the track system opposite ends of the track transition device can be fixed by the end contact means on the track transition device.

If the coupling deflector means have at least one clamping section which can be clamped between the end face of a respective molded body and at least one corresponding end contact means, then no additional components such as screws or the like are required to attach the coupling deflector means to the track transition device.

In order to be able to provide a suitable position fixation of the same even in the case of relatively wide shaped bodies, it is proposed that a plurality of fixing rod means arranged at a distance from one another transversely to the longitudinal direction of the track system are provided with the associated end angling means and intermediate contact means.

In order to be able to prevent the storage of the molded bodies on the track system from being impaired by the fixing rod means by the provision of the at least one fixing rod means in a track transition device, it is proposed that the at least one fixing rod means can be arranged in an assigned channel in the molded bodies.

It can be provided, for example, that the channel is an open channel, which is preferably formed on an underside of the molded body in the longitudinal direction of the track system. Such a design is particularly advantageous in the case of molded articles made of plastic, since in this case the formation of an open channel is an easy operation.

Alternatively, however, it can be provided that the channel is formed by a through opening formed in the shaped bodies, preferably in a central height region thereof. Such a configuration is particularly advantageous if the molded body is made of, for example Concrete or steel are made since the provision of through openings is easily possible with such materials.

The end contact means can comprise a contact piece which can be brought into contact with the respective end faces of the shaped bodies.

It is then advantageously provided that the contact piece can be brought into contact with the respective end face of a shaped body in such a way that the contact piece lies against the end face at least in an area arranged above a height center of the shaped body. Since in the area of the end contact means the shaped bodies are not supported on further shaped bodies, but rather the end abutment means form the only abutment points for the shaped bodies, with such a configuration, when the molded bodies are in contact with one another under tension, the shaped bodies can be pressed out in the end regions be avoided upwards.

In the device according to the invention it can be provided that the contact piece is formed by an intermediate contact element of a fixing rod piece, which fixing rod piece is assigned to a last shaped body in the longitudinal direction of the structural unit. With such a configuration, no special fixing rod pieces have to be provided for the last shaped bodies in the longitudinal direction of the structural unit; the fixation rod pieces used for all other shaped bodies located in the center area of the structural unit can be used. Advantageously, the end contact means and / or the at least one intermediate contact means positively engage the respective shaped bodies in a height direction that is essentially orthogonal to the longitudinal direction of the track system.

The invention further relates to a track transition device on a track system, comprising a plurality of in a longitudinal direction Track system successive, preferably abutting moldings and at least one device according to the invention for fixing the position of the moldings.

If the track system includes sleepers, for example, on which rails are mounted at a lateral spacing from one another, then it is advantageous if the extension of the moldings in the longitudinal direction of the track system is an integer multiple of a threshold distance and if at least one impact between two consecutive moldings over one Threshold lies. In particular, it can be prevented that the molded bodies are displaced relative to one another in the region of the joint between two immediately successive molded bodies and that the molded bodies may be damaged in the process.

Advantageously, the track transition device arranged between rails of a track system means shaped bodies, in which case at least two fixing rod means with the associated end contact means and intermediate contact means are provided for fixing the position of the center shaped bodies parallel to one another in the longitudinal direction of the track system with a lateral spacing from one another. Since the central molded bodies extend over the entire area between the two rails of a track system and thus have a relatively large width, the molded bodies can be securely fixed over their entire width by providing at least two fixing rod means.

In addition, it can be provided that the track transition device comprises outer moldings arranged on an outer side of rails and that at least one fixing rod means extending along the outer moldings with the associated end contact means and intermediate contact means is provided for fixing the position of the outer shaped bodies. In order to be able to hold the outer moldings on the track system independently of the tiling of a road adjacent to the track transition device, it is proposed that the outer moldings are further held on the track system by means of holding means which are attached to sleepers of the track system and are essentially U-shaped , wherein the U-shaped holding means engage in a receiving channel on an underside of the outer molded body.

The invention further relates to a method for constructing a track transition device on a track system with a plurality of molded bodies following one another in a longitudinal direction of the track system, preferably abutting one another, and at least one device according to the invention for fixing the position. The process includes the following steps:

a) arranging a shaped body on the track system; b) arranging at least one fixing rod piece in an assigned channel of the one molded body, c) arranging another molded body preferably in abutment against the one molded body, d) arranging at least one fixing rod piece in an assigned channel of the other molded body, e) engaging one first connecting section of the at least one fixing rod piece assigned to the further molded body with a second connecting section of the fixing rod piece assigned to the one molded body.

Steps a) to e) are preferably repeated successively to set up the track transition device.

The method according to the invention can furthermore include the engagement of an intermediate piece with the first connecting section of the at least one fixing rod piece assigned to the one molded body and the successive sive repetition of steps a) to e) on both sides of one shaped body in the longitudinal direction of the track system, the at least one fixing rod piece of a shaped body immediately following the one shaped body on the side of the intermediate piece in step e) engaging with its first connecting section is brought to the adapter. In such a procedure, it is preferable to start from a center of length of the track transition device, that is to say the structural unit, and then to add it to both sides. This has the advantage that in the event that, for example, due to manufacturing tolerances, the length of the molded parts deviates slightly from a threshold distance in the longitudinal direction, the accumulation of the length deviations is halved on both sides, starting from the central molded body, so that it can be avoided even with longer track transition devices that due to the accumulation of differences in length between the molded bodies on the one hand and the distance between the welds on the other hand, an impact between two molded bodies in the longitudinal direction is not above a threshold.

The method according to the invention preferably further includes fixing the structural unit with respect to the track system.

In Figures 1, 1 a and 1 b rails of a track system are designated 10. The rails are fixed on sleepers 14 by clamping devices 1 2. The sleepers 14 lie in a ballast bed 11, a surface of the ballast bed 11 being essentially flush with the surface of the sleepers 14.

Between the rails 10 are arranged in a longitudinal direction of the track successively middle-shaped body 1 6, each engage in their rail near areas under rail heads of the rails 1 0 and form an intermediate space for the free running of the train wheels. On the outer sides of the rails 10, outer molded bodies 18, 20 are arranged one after the other in the longitudinal direction of the track system, the outer molded bodies 18, 20 in turn engaging under the rail heads in their regions near the rails. Both the central molded bodies 1 6 and the outer molded bodies 1 8, 20 are in their end regions close to the rails 10. - Lo ¬ chen each mounted on rail shaped bodies 13 which correspond in length substantially to the distance between two immediately following sleepers 14 and which each have half-recesses in their end regions for receiving one half of the clamping devices 12. The central molded body 16 and the outer molded body 18, 20 are thus secured against lifting upwards.

Both the central shaped bodies 16 and the outer shaped bodies 18, 20 can essentially correspond in their structure to the shaped bodies known from DE-42 29 289-A1, the content of which is incorporated herein by reference as part of the disclosure. In such a case, the central molded bodies 16 and the outer molded bodies 18, 20 are made of plastic material, in particular of rubber material. In principle, however, it is also possible to make shaped articles of this type from other materials, such as e.g. To produce concrete, steel or the like.

As described in detail below, both the central molded bodies 16 and the outer molded bodies 18, 20 are each coupled to one another by fixing rods 22 in order to be able to provide a positional fixation of the track transition device constructed in this way. In particular, the position fixation with reference to the central molded body 16 is described in detail below. It is self-evident for the person skilled in the art that the same also applies to the position fixing of the outer molded bodies 18, 20. If there are differences in the position fixing of the central molded body 16 and the outer molded body 18, 20, it is pointed out below. As can be seen in FIGS. 2a to 2c, the individual center shaped bodies 16 are fixed by the fixing rods 22 in end regions 24 (FIG. 2a) and 26 (FIG. 2c) of the track transition device by end angles 28 serving as end attachment means, which in the following described manner are fixed to the fixing rod 22. In an intermediate region 30 located between the end regions 24, 26 (for example in FIG. 2b), the fixing rod 22 is used as an intermediate contact means for the central molded bodies 16 warping plates 32 coupled, which engage in the manner described below between two directly adjacent center moldings 1 6 and thus contribute to fixing the position of the center moldings 1 6 in the intermediate regions 30. In order to obtain a good positional fixation of the individual molded bodies, the central molded bodies 16 can be held together, for example, by two fixing rods 22 running parallel to one another, while the outer molded bodies 18, 20, which are narrower in width, are each held by a single fixing rod 22 can be held together. Furthermore, a fixing rod fastener 34 is fixed in the intermediate area 30 by screws 80 to one of the sleepers 14. The Fixierstangenbef estiger 34 serves to fix the fixing rod 22 with respect to the track system, in particular to facilitate the construction of such a track transition device, as described below.

The device according to the invention is shown in detail in FIGS. 3a and 3b.

As can be seen in FIGS. 3a and 3b, the fixing rod 22 comprises a threaded rod with an external thread extending over its entire length (only the threads in the respective end regions are shown in FIGS. 3a and 3b). Such bars are known for example in the construction industry as reinforcing steel bars. These steel rods have on their outer circumference a thread or thread sections with a relatively large thread pitch (pitch) in the range of 5-1 2 mm, onto which complementary nut parts can be screwed. In order to be able to provide a self-locking of such nuts on the rods in spite of the large thread pitch, the sections of the thread-forming sections projecting from the peripheral surface of the rods are conically shaped in their cross section with relatively flat slopes of their flanks, so that the pressure on them Threaded nuts a jamming of the nuts occurs on the relatively flat thread flanks. The provision of steel bars with a relatively large thread Slope, as can be seen below, has the advantage that if the individual nut parts are to be moved forward on the rods over longer distances by rotation, a relatively large forward movement of the nut parts is caused when the nut parts are rotated.

3a and 3b, several fixing rod elements 36, 38 can be coupled to one another by a screw sleeve 40, the screw sleeve 40 being countered in its end regions by lock nuts 43, 42, so that a secure cohesion of the fixing rod elements 36, 38 is ensured (see also FIG. 4b). The end brackets 28 are provided in each end region of the fixing rod 22. As can also be seen in FIG. 6, the end brackets 28 each comprise a tube piece 48, preferably a square tube piece 48, on which a contact piece 50 is fixed essentially at right angles thereto, for example by welding or the like. The pipe sections 48 are each pushed onto the fixing rod 22 and an anchoring nut 54 is screwed onto the end regions 44, 46 of the fixing rod 22, which has a radial flange 56 and against which the pipe section 48 can come to rest in the assembled state. Nuts 58 and 60 are provided inside and outside the anchoring nut 56, respectively. In this case, the nut 58 is provided at an axial distance from the anchoring nut 54, which serves to ensure that the pull rod 22 is carried essentially centrally in the tubular piece 48 when the tubular piece 48 abuts the radial flange 56 of the anchoring nut 54. The nut 60 serves in each case to counter the anchoring nuts 54, in order thus to avoid an unintentional displacement of the end angles 28.

Depending on the number of shaped bodies to be fixed, a plurality of the package printing plates 32 are arranged between the two end angles 28. Each of the package printing plates 32 is associated with a pair of lock nuts 62, 64.

CORRECTED SHEET (RULE 91) ISA / EP As can be seen in FIGS. 10a and 10b, the package printing plates 32 each have through openings 66, the diameter of which is dimensioned such that the package printing plates 32 are freely displaceable on the fixing rod 22. The packet pressure plates 32 can then be fixed at the desired location on the fixing rod 22 by means of the lock nuts 62, 64. The package pressure plates 32, like the end brackets 28, can each be arranged on the fixing rod 22, for example before the end brackets 28 are attached, with their lock nuts 62, 64 at predetermined preassembly positions.

As can also be seen in FIG. 3 b, in the region of the fixing rod 22 located between the ends 44, 46 a pair of lock nuts 68, 70 are also provided, which include two disks 72, 74 which can be displaced on the fixing rod 22. The lock nuts 68, 70 serve to fix the fixing rod 22 to a fixing section 76 of the fixing rod fastener 34. As can also be seen in FIGS. 7a and 7b, the fixing rod fastener 34 has a fastening section 78 and the one fixed on the fastening section 78, for example by welding essential U-shaped fixing section 76. FIGS. 7a and 7b show a fixing rod fastener 34 which is designed to be attached to wooden sleepers by means of screws 80. In the figures. 8a and 8b there is shown a corresponding fixing rod fastener 34 "which is designed for attachment to concrete or metal sleepers. The design of the fixing rod fastener 34" essentially corresponds to that of the fixing rod fastener 34, but the fastening section 78 "has angled end regions 82" and 84 The profile of the fastening section 78 is designed such that it essentially corresponds to the circumferential profile of metal or concrete sleepers on the upper side thereof. The fixing rod fastener 34 "is then placed only on such sleepers and thus forms a fixed point for the fixing rod 22 in the longitudinal direction of the track system by means of positive engagement. With reference to FIGS. 4a to 4d, the interaction of the device according to the invention for fixing the position of the moldings with the moldings deposited on a track system is described in detail below.

FIG. 4a shows the end region 24 in which the end bracket 28 bears against its end piece 88, with the interposition of a coupling deflector 86 described below, on an end face 88 of a last central molded body 16 in the longitudinal direction of the track transition device. The pipe section 48 of the end bracket 28 extends in a channel 90 formed on the underside of the central molded body 16 (see also FIG. 1 a). In this channel, the fixing rod 22 extends along the entire length of the track transition device formed from the central molded bodies 1 6 and outer molded bodies 1 8 and 20. The support of the shaped bodies 16, 18, 20 on the track system is thus not impaired by the fixing rod 22. Since the end brackets 28, on the one hand, rest with their contact pieces 50 on the middle shaped bodies 1 6 and, on the other hand, with their pipe pieces 48 extend in the channel 90 and thus rest against an underside of the middle shaped bodies, then when the middle shaped bodies 1 6 are held under tension between respective end angles 28, tilting of the end angles 28 counterclockwise in FIG. 4a can be avoided. Thus, even in the state in which the central moldings 1 6 are under tension, correct positioning of the end angles 28 with respect to the central moldings 1 6 and thus correct contact of the contact pieces 50 on the corresponding end faces is guaranteed. The tilt-inhibiting effect of the pipe pieces 48 can be improved with increasing length of the same.

The formation of the channels 90 on the underside of the central molded bodies 1 6 is particularly advantageous when the central molded bodies 1 6 are made of

Plastic material, in particular made of rubber material, since such a channel open to an outside in a simple manner Manufacture of the molded body formed from plastic material can be provided.

As can also be seen in FIG. 4a, the tube piece 48 abuts the flange 56 of the anchoring nut 54, so that the end bracket 28 is fixed in its position in the longitudinal direction of the track system. As can be seen, the contact piece 50 is dimensioned such that it extends from the tube piece 48 in a height direction h to such an extent that it protrudes over a region of a height center m of the central molded parts 16. If the middle molded bodies 1 6 are held together by the fixing rod 20 with the end contact means 28 in such a way that they are under tension, which can be the case, for example, at relatively high outside temperatures at which the middle molded bodies 1 6 expand, then try the Dodge middle molded body 1 6 due to the squeeze between the end angles 28 upwards. However, since the end brackets 28 also engage the central shaped bodies 16 via the shaped pieces 50 above the middle height m, such an evasive movement can be counteracted. In addition, it can be avoided that the central shaped bodies 16, which are located at the ends of the track transition device and are not supported on further shaped bodies, do not shift upwards with respect to the abutment pieces 50 due to a tension that may occur in the installed state and thus the engagement between the end angles 28 and the corresponding central molded bodies 1 6 is lost. The advantage of such a configuration of the end angles 28 is particularly evident when the individual shaped bodies are heated by solar radiation. The upper area of the shaped bodies which is directly exposed to solar radiation heats up more than a lower area, which leads to a correspondingly greater expansion of the shaped bodies in their upper area. This greater expansion in the upper region can then also be counteracted by the abutment of the contact pieces 50 above the region of the middle m. As already mentioned, the contact piece 54 of the end bracket 28 bears against the end face 88 of the central molded body 1 6 via the coupling deflector 86. Such a clutch deflector is shown in detail in FIGS. 5a to 5c. The clutch deflector 86 is formed by an essentially angularly shaped part which comprises a clamping part 92 and a clutch deflector part 94. A reinforcing part 96 is attached between the clamping part 92 and the coupling deflector part 94, for example by welding. The clamping part 92 has two clamping sections 98, 100 which extend in the lateral direction and on which the contact pieces 50 of the end brackets 28 come to rest. Since, as can also be seen in particular in FIGS. 1 a and 1 b, the central shaped bodies 16 are fixed to one another by two fixing rods 22 arranged laterally at a distance from one another, the coupling deflector 86 can be clamped between the end angles in each case 28 and the end face 88 of the last shaped body 16 in each case are held firmly on the track transition device. The coupling deflector is used, in a known manner, to prevent a coupling depending from a train from damaging the center molded bodies 16 when it strikes the track transition device.

As can be seen in particular in FIGS. 4a and 4b, the central molded bodies 1 6 are formed in their opposite end faces 88, 1 02 with groove sections 104 and spring sections 1 06 (see also FIGS. 1, 1 a, 1 b). When the end faces 88, 102 abut one another, the spring sections 1 06 each engage in the groove sections 1 04 and thus form a positive engagement between the individual central shaped bodies 1 6.

As can be seen in FIGS. 4a and 5a to 5c, the clutch deflector 86 also has a corresponding one on its clamping part 92

Spring section 1 08 or 1 10, each between the groove or

Spring sections 1 04, 1 06 engages. It is the clutch deflector over a maximum possible contact surface on the end face 88 of the central molded body 1 6. In addition, this enables a positive interlocking of the coupling deflector 86 with the central shaped bodies 16 in the height direction h. This represents an additional safeguard for the central molded bodies 16 in the end regions of the track transition device against lifting upwards. It can also be provided that, for example, teeth or the like are additionally provided between the coupling deflector 86 and the contact pieces 50, to also provide a positive interlocking between these two components in the height direction h.

Since in the end regions of the track transition device outside the rails 10, ie in the region of the outer molded bodies 1 8, 20, no coupling deflector is clamped by the end brackets 28, an outer molded body pressure plate 1 1 2 is in each of these regions between the contact piece 50 the end angle 28 and the respective end face of the outer molded body 1 8, 20 clamped (Fig. 1 b). The pressure exerted by the contact piece 50 on the outer moldings 18, 20 can thus be distributed over a larger area. Such an outer molded body pressure plate 1 1 2 is shown in FIGS. 9a and 9b. The outer molded body pressure plate 1 1 2 again has a spring section 1 1 4, which can engage in a groove 104 or between spring sections 106, as described above with reference to the clutch deflector 86 and the central molded body 1 6. If, for structural reasons, it is not necessary to provide coupling deflectors for the central molded bodies 16, a component corresponding in its structure to the external molded body pressure plate 1 1 2 can, of course, in each case between the end angles 28 and the corresponding end faces of the central molded bodies 1 6 can be clamped. In addition, the end brackets 28, for example, interlocking interlocking teeth can also be provided on the outer molded body pressure plates 1 1 2 and the abutment pieces 50 interacting with them, in order to form a shape again in the vertical direction. conclusive setting of the outer molded body pressure plates 1 1 2 and thus the outer molded bodies 18, 20 to avoid with respect to the end angle 28.

FIG. 4c shows the fixing rod 22 fixed on a threshold 14 by means of the fixing rod fastener 34 or 34 ". In this illustration, the threshold 14 is shown such that it comprises a wooden threshold in its left half and a wooden threshold in its right half Metal or concrete sleeper is formed. Depending on this, the fixing rod fastener 34 or 34 "is then configured as described with reference to FIGS. 7a, 7b and 8a, 8b. As can be seen in FIG. 4c, the fixing section 76 is fixed with respect to the fixing rod 22 with the washers 72, 74 being interposed by the lock nuts 68, 70.

FIG. 4d shows the interaction of the package pressure plates 32 with the central shaped bodies 1 6. It is obvious to the person skilled in the art that the tie rod 22 with the package pressure plates 32 interacts with the outer shaped bodies 18, 20 in a corresponding manner. In FIG. 4d, the middle molded body 1 6 in the illustration lies with its end face 102 against the front face 88 of the right molded body 1 6 in the illustration, the spring sections 1 06 engaging in the grooves 104. As can also be seen in particular in FIG. 1 a, a recess 116 is formed in the end face 88, in which the package pressure plate 32 can be received, so that the arrangement of the package pressure plate 32 allows two directly adjoining central molded bodies 16 to be applied , 1 6 on their end faces 88, 102 not impaired. The depth of the recess 1 16 is designed such that it corresponds essentially to the thickness of the package printing plate 32. In a corresponding manner, the lower spring 106 is also interrupted on the end face 102 in order to enable the package pressure plate 32 to be arranged. In the state shown in FIG. 4d, the package pressure plate 32 thus comes to rest both on the end face 102 of the left central molded body 1 6 and on the front side 88 of the right central molded body 1 6 in the illustration. Pressure plate 32 is thus each of the two central molded bodies 1 6, 1 6 in its position in the longitudinal direction of the track system can be fixed in one orientation. By arranging a plurality of such package printing plates 32 on the fixing rod 22, as shown in FIGS. 3a, 3b and 2a to 2c, a plurality of fixing points for the central shaped bodies 16 (and in a corresponding manner also for the Outer molded body 1 8, 20) formed in the longitudinal direction of the track system on the fixing rod 22. It can be provided that several, for example two, molded bodies are arranged between two successive package printing plates 32, which then form so-called molded body packages. Nevertheless, it is also possible to arrange a package printing plate 32 after each shaped body or to combine more than two shaped bodies into one package.

As can be seen in FIG. 4d in particular, the package pressure plate 32 is designed such that it extends only slightly between the two central molded bodies 1 6 and does not extend to the region of the center height m of the central molded bodies 1 6. Such a dimension of the package printing plate 1 6 is sufficient for fixing the central molded bodies 1 6 in the longitudinal direction; in particular, the center moldings 1 6 lie against one another in their area arranged above the parcel printing plate 32, so that even when the center moldings 1 6 are arranged under tension it can be avoided that they move upwards and out of engagement during an evasive movement could move with the package pressure plate 32. As can also be seen in FIG. 4d, an intermediate space is provided between an upper edge 33 of the package printing plate 32 and a surface 1 1 7 of the central molded body 1 6 in the height direction h which delimits the recess 11 6 upwards. This intermediate space serves to load the middle shaped bodies 1 6 from above, e.g. when driving through a truck, to avoid that the surface 1 1 7 comes to rest on the upper edge 33 of the package pressure plate 32. It can thus be avoided that the package pressure plate 32, which is supported downward against the threshold 14, becomes excessive

CORRECTED SHEET (RULE 91) ISA / EP presses against the surface 1 1 7 and thereby causes damage to the central molded body 1 6.

Since the moldings (central moldings 1 6 and external moldings 1 8, 20) in the longitudinal direction of the track system are held on the one hand between the respective end angles 28 on the fixing rods 22 and on the other hand, additional fixed points are provided for the individual moldings packages between the end regions of the track transition device , can be prevented that when the individual moldings are subjected to a force, a large number of the moldings are displaced in the longitudinal direction of the track system in such a way that relatively large gaps are formed between the moldings. By forming individual packages, it is also possible to counteract the changes in length of the central molded bodies 1 6 and outer molded bodies 1 8, 20 that occur due to temperature fluctuations by suitable adjustment of the package pressure plates for the individual molded body packages. By means of the device according to the invention, all of the central shaped bodies 1 6 and outer shaped bodies 1 8, 20 are each combined into one unit. This makes it practically impossible to move the entire molded body combined into one unit in the longitudinal direction of the track system.

A procedure is described below with which a track transition device can be constructed using the device according to the invention. It is first on the track system, for example one of the sleepers 14, for each fixing rod 22 provided (two for the central moldings 1 6, one for the external moldings 1 8, 20) a fixing rod fastener 34 or 34 ", depending on the type Thereafter, the fixing rods 22 are laid down oriented in the longitudinal direction of the track system and are preferably attached to the fixing sections 76 and 76 "of the fixing rod fasteners 34 and 34" in the longitudinal middle regions in the manner described above Fixing rods 22 with the respective end angles 28, Package printing plates 32 and the associated lock nuts are delivered as preassembled units in which the end brackets 28 or the package printing plates 32 are already approximately arranged in their final assembly positions.

After fixing the fixing rods 22 to the fixing rod fasteners 34 and 34 ", one of the lock nuts, for example the lock nut 62 in FIG. 4d, is brought into the intended final assembly position for each fixing rod 22. In order to ensure a suitable installation, all of these lock nuts must be used 62 adjacent fixing rods for a series of shaped bodies are arranged in a line orthogonal to the longitudinal direction of the track system, then a first central shaped body 1 6 or outer shaped body 18, 20 is deposited on the track system in a known manner, the end face 102 of the middle molded body 1 6 (and in a corresponding manner for the outer molded bodies 1 8, 20) ends flush with the lock nut 62 (see FIG. 4d). Then the package pressure plate 32 comes into contact with the lock nut 62 and the end face 1 02 of the central molded body 1 6. Subsequently, the second lock nut 64 is tightened for the package pressure plate 32, whereby, as in FIG. 1 0a, openings 1 20, 1 22 are provided on the package pressure plate 32, into which a suitable screw wrench can engage in order to prevent the package pressure plate 32 from rotating when the lock nut 64 is tightened. After the first package pressure plate 32 has been fastened, the first lock nut 62 for the next package pressure plate 62, for example by means of a spacing gauge, corresponds at a predetermined distance, which essentially corresponds to the extent of the central molded body 16 or outer molded body in the longitudinal direction of the track system 32 brought into their intended mounting position.

It should be pointed out here that, for example, screws can be screwed into the respective shaped bodies through the openings 1 20, 1 22 of the package pressure plate 32 in order to ensure a positive interlocking of the package pressure plates 32 with the respective ones in the height direction h To produce moldings. This is particularly advantageous if the package pressure plate does not come to lie directly above a threshold and thus the package pressure plate can move downward under load and this could possibly move out of engagement with the respective shaped bodies. It goes without saying that other means, such as, for example, projections on the package printing plates or the shaped bodies and recesses on the other components, can be provided in order to provide the interlocking interlocking between the package printing plates and the respective shaped bodies.

Subsequently, the next central molded body 1 6 (or outer molded body 1 8, 20) is placed on the track system in such a way that its end face 88 abuts the end face 1 02 of the previously stored central molded body 1 6, so that grooves 104 and springs 106 engage one another. The already assembled package pressure plate 32 is received in the recess 1 1 6 in the end face 88 (see FIG. 4d).

After depositing this central molded body 16, the next package pressure plate 32 is then brought into contact with its lock nut 62 and, as described above, locked with the second lock nut 64. This process is preferably repeated starting from the length center of the fixing rods 22 until an end of the track transition device is reached. At this end, as described above, the end angles 28 are then either with the coupling deflector 86 temporarily stored in the middle shaped bodies 16 or with the outer shaped body pressure plates 11 2 in the outer shaped bodies 18 , 20 attached. The first half of the track crossing device is then completed. For the second half of the track transition device, the same process is repeated in the opposite direction until the end region of the track transition device is also reached there. In this second end area, too, the end brackets 28 are then either temporarily stored with the coupling deflector 86 (in the case of the middle shaped bodies 1 6) or the outer shaped body pressure plates 1 1 2 (in the case of the outer shaped bodies 1 8, 20). After this process has been completed, the track crossing device is completed. It should be noted that the assembly process has been described above in such a way that a package printing plate is arranged on each molded body. However, this is not mandatory; As already mentioned, several shaped bodies can be combined to form a package, in which case a package printing plate is then always arranged according to the number of shaped bodies which form a package. Should readjustment be necessary after a long period of operation, the package pressure plates 32 or the end brackets 28 can be moved into their new position simply by adjusting the respective lock nuts, since no screwing with the screws can be changed got to.

It is obvious to a person skilled in the art that the assembly process can also be started by first fixing a package pressure plate 32 with its lock nuts 62 and 64 to the fixing rod 20 and only then placing the first molded body down. In addition, it is possible to start the building process from one end, i. H. first the end brackets 28 are fixed at one end of the fixing rods 22 and then the first lock nut for the first package pressure plate 32 is attached in its predetermined mounting position. Then one shaped body or several shaped bodies is deposited adjacent to the end angle 28, depending on whether the shaped body packages consist of one or more shaped bodies. The package pressure plate is then attached to the corresponding contact surface using the lock nut, i.e. Face of the molded body, brought into contact.

Since in the finished state the fixing rods 22 are still held on the track system via the fixing rod fasteners 34 and 34 ", the fixing rod fasteners 34 and 34" see the fixing of the fixing in addition to the position. rods 22 during the assembly process an additional fixation of the track transition device on the track system.

Since the outer molded bodies 1 8, 20 rest against the rails 10 only in one of their lateral end regions, additional holding elements are provided in order to achieve better retention of the outer molded bodies 1 8, 20 on the track system, independently of an accumulation. As shown in Fig. 1 a in connection with the outer molded body 1 8, a U-profile part 1 24 is attached to the threshold 14 at a lateral distance from the rail 1 0 such that it points upwards with its open end. The U-profile part 1 24 is attached to the threshold 1 4 in such a position that after arranging the outer moldings 1 8 on the track system, the channel 90 comes to lie exactly above the U-profile part 1 24, thus making the U-profile part 1 24 provides a lateral position fixation for the outer moldings 1 8. In the interior formed by the U-profile part 1 24, the fixing rod 22 can then be arranged in an unhindered manner. However, in order to avoid mutual interference of the U-shaped parts 1 24 each with parcel printing plates 32, it is provided that the profiled parts 1 24 are only provided on every second sleeper and that the parcel printing plates 32 are then arranged in the areas of the remaining sleepers 1 4 are. In particular, it can be provided that the length of the outer molded bodies 18 and 20 are designed such that they extend over two sleepers. Then the U-shaped part 1 24 can be arranged in each case on the threshold lying in the middle region of the outer molded bodies 1 8, 20 and the package pressure plates 32 can be located in the end regions.

During assembly, the respective shaped bodies can be fixed to one another by the end abutment means or the intermediate abutment means in such a way that they are pretensioned to one another, or the individual shaped bodies can only be easily brought into abutment, for example when assembling at low temperatures that

CORRECTED SHEET (RULE 91)

ISA / EP with a rise in temperature and a corresponding expansion of the molded body, a pretension is generated.

A track transition device has been described above, in which the joints between two directly adjacent middle shaped bodies 1 6 or outer shaped bodies 1 8, 20 lie directly above a threshold, as can be seen in FIGS. 2a-2c. This has the advantage that when the center moldings 1 6 or the outer moldings 1 8, 20 are immediately adjacent to the joints, two successive center moldings 1 6 or outer moldings 1 8, 20 cannot shift relative to one another . In addition, with such a configuration, each of the package printing plates is also arranged directly above a threshold, so that any bending of the fixing rods 22 which may occur during operation in areas located between thresholds 14 cannot lead to the package printing plates 32 being in relation to the central shaped bodies 1 6 or move the outer molded body 1 8, 20 and the position fixing effect is lost. Nevertheless, it is also possible, for example, to provide slot-like recesses for package printing plates in a center length region of the central molded bodies 1 6 and / or the outer molded bodies 1 8, 20 and then to arrange the package printing plates in each case between two sleepers 1 4 such that they slot into them ¬ engage recesses.

The device according to the invention can be used both with relatively large track crossing devices, as are required in the area of motorways, and with smaller track crossing devices, such as those used, for. B. are required on foot or bicycle paths. In the second case, it can be provided that the two clamping sections of the coupling deflector extend further outwards and in each of their outer regions have through-openings 1 50, 1 52 (FIG. 5 a), which are then penetrated by the fixing rods. That is, with such a configuration it is possible to use the end angle to dispense with and to provide an anchoring nut or a lock nut on the fixing rods directly adjacent to the extended clamping sections of the coupling deflectors. In this case, the coupling deflectors or their clamping sections serve as the end contact means of the device according to the invention.

An alternative embodiment of the device according to the invention and the molded body are shown in FIGS. Components which correspond to components shown in the above-described embodiment are identified by the same reference numerals with the addition of an appendix "a".

As can be seen in FIG. 1 1 and in the simplified sectional illustration in FIG. 1 2, the shaped bodies 1 6a, 1 8a, 20a of this embodiment have a through channel 1 7a, which is formed in the circumferential direction and is formed approximately in the central height region thereof. In the case of a plurality of molded bodies 1 6a, 1 8a, 20a which are arranged in succession in the longitudinal direction, the channels 17a form a through-channel in all molded bodies for the fixing rods 22a which are each constructed from a plurality of fixing rod pieces 38a. By means of the fixing rod pieces 38a described in detail below, two shaped bodies 1 6a of the central shaped bodies 1 6a arranged between the rails 10a are combined to form a group of molded bodies or a package of molded bodies, ie a fixing rod piece 38a is assigned to each fixing rod 22a for each molded body group. In the case of the outer molded bodies 1 8a, 20a arranged outside the rails 10a, the molded body groups or packages are each formed by a single molded body 1 8a or 20a, ie a fixing rod piece 38a is assigned to each molded body 1 8a or 20a. The individual packages are then combined by the fixing rods 22a to form the structural unit. 1 3 shows the simplified basic principle for the construction of the individual fixing rod pieces 38a. Each fixing rod piece can be constructed, for example, with a threaded rod 230a which carries an externally threaded section 1 36a at least in one of its end sections. In the other end region, each fixing rod piece carries a hexagon section 1 32a, which has an opening 134a with an internal thread. Furthermore, a radial flange 1 30a is arranged adjacent to the hexagon section 1 32a, which serves as an intermediate contact means 32a or as an end contact means 28a in the manner described below. The external thread section 1 36a and the internal thread opening 1 34a are matched to one another in such a way that the external thread section 1 36a of a fixing rod piece 38a can be screwed into the internal thread opening 1 34a of an immediately following fixing rod piece 38a. Furthermore, an intermediate piece 1 38a is provided, which likewise has a radial flange 1 30a and on each side thereof a hexagonal section 1 32a, each with an internal thread opening 1 34a.

To set up a track transition device according to FIGS. 1 1 to 24, the procedure is as follows:

A shaped body to be provided in the middle of the length of the track transition device or a shaped body group consisting of two central shaped bodies 1 6a, 1 6a or in each case one outer shaped body 1 8a, 20a is preferably arranged on the track system. These shaped bodies 1 6a, 1 6a, 1 8a, 20a, which are to be arranged as the first, are shown hatched in FIG. 14. Then a fixing rod piece 38a is pushed through the channels 1 7a of each of these shaped bodies 1 6a, 1 8a, 20a until the radial flange 1 30a of the same comes into contact with an end face 88a or 102a of the shaped bodies 1 6a, 1 8a, 20a. As can be seen in FIG. 1 1, a recess 1 1 6a for receiving the radial flanges 1 30a is formed on an end face 88a of the molded body. After the insertion of these fixing rod pieces 38a, the shaped bodies 1 6a, 1 8a, 20a become intermediate pieces from the other side in the longitudinal direction 1 38a with one of its internal thread openings 1 34a is screwed onto the external thread sections 1 36a of the fixing rod pieces 38a already introduced and tightened by engaging a tool with the external hexagon 1 32a. The two central molded bodies 1 6a are thus already combined to form a first molded body group. 14, a further row of shaped bodies 16a, 16a, 18a, 20a is arranged on the left side of the shaped bodies 1 6a, 1 8a, 20a shown in hatched lines and inserted into each of the channels 1 7a contained in these shaped bodies Fixing rod piece 38a inserted and screwed with its external thread section 1 36a into the internal thread opening 1 34a of the fixing rod pieces 38a already provided in the hatched shapes and fixed by tightening. This process is repeated successively until the end of the track transition device or the molded body combined to form a structural unit is reached in a longitudinal direction. Simultaneously or subsequently, this process can be repeated on the other side in the longitudinal direction, ie on the right side in the illustration according to FIG. 1 4. After a first row of molded articles has been deposited, following the hatched articles, fixation rod pieces 38a are again introduced into the channels 1 7a of this row of molded articles and with their external thread sections 1 36a in internal thread openings 1 34a of the molded articles 1 6a, 1 8a, 20a shown in hatched lines provided intermediate pieces 1 38a screwed and tightened. The process is also repeated on this page until the end of the assembly is reached.

With the last fixing rod pieces 38a in the longitudinal direction, by means of which the center shaped bodies 1 6a are combined, coupling deflectors 86a can be coupled to the track transition device, as described above.

Mounting brackets 200a can be used to fix the track transition device with respect to the rail system, as in FIG. 22 shown. The fastening angles 200a have a first angle leg 202a with a plurality of screw openings 204a and have a second angle leg 206a which is approximately orthogonal to the first angle leg 202a. The fastening angles 200a are fixed with their first angle leg 202a on the threshold 14a which lies in the longitudinal direction under the free end of the last shaped bodies 1 6a, 1 8a, 20a. The fastening angles 200a are arranged with their second angle legs 206a in contact with the end faces 88a and 102a of the last shaped bodies 16a, 18a, 20a of the structural unit or track transition device in the longitudinal direction. This prevents the entire assembly from shifting in both longitudinal directions.

The mounting bracket 200a shown in Fig. 22 is designed to be fixed to wooden sleepers, i.e. fastening screws can be screwed through the screw openings 204a and into the wooden sleepers.

FIGS. 23 and 24 show a type of configuration of a fastening angle 200a ′ which is designed to be fixed to a concrete sleeper. The mounting bracket 200a 'has two angle parts 208a' and 210a '. The angle part 208a 'essentially corresponds to the fastening angle 200a shown in FIG. 22. The angle part 21 0a 'in turn has two angle legs 21 2a' and 214a ', which are bent in a V-shape relative to one another to adapt to an inclined surface 15a' of a concrete sleeper 14a '. Bracing elements 21 6a 'are fixed between the angle legs 21 2a', 214a ', for example by welding. The angle part 208a 'is firmly connected to the angle part 210a' by means of screw bolts 220a '. The procedure for fixing the track transition device with respect to the track system is such that a mounting bracket 200a 'is placed between the molded body 16a' and the threshold 14a 'before, for example, placing a last shaped body in the longitudinal direction or simultaneously with this process, so that the angle leg 214a 'of the angle part 210a' bears against the threshold 14a 'and the angle leg 222a' of the angle part 208a 'bears against an end face 88a' of the molded body 16a '.

Since, as already described above with reference to the first embodiment, the shaped bodies 16a with their lateral edge areas engage under the rail heads of the rails 10, although there is no forcible fastening of the shaped bodies to the fastening angles in the fastening angles 200a or 200a ' the danger that the last shaped bodies 16a in the longitudinal direction of the track transition device can be brought out of engagement with the fastening angles 200a or 200a 'in an undesired manner.

As with the shaped bodies 16a, the fastening angles 200a or 200a 'are also provided in the shaped bodies 18a or 20a arranged outside the rails 10a. It is pointed out that, although in the illustration according to FIG. 11 and according to FIG. 14 the fastening angles 200a act on the last shaped bodies in the longitudinal direction, fastening angles can also be provided in an intermediate region, which then act on the shaped bodies with their Angle legs engage between two successive shaped bodies in the longitudinal direction or engage in a recess provided on an underside of a shaped body. As an alternative or in addition to the fastening using the fastening brackets described above, it is also possible for the fastening rods 22 constructed from individual fixing rod pieces 38a and described above with reference to the embodiment of FIGS. 1 to 10 to be fixed directly to sleepers by means of corresponding fastening elements. This is possible, in particular, in the case of an embodiment in which the fixing rods 22a lie in channels of the shaped bodies which are open at the bottom. As can be seen in FIG. 11, the shaped bodies 1 6a, 1 8a and 20a are constructed essentially in accordance with the embodiment form according to FIGS. 1 to 10, ie these shaped bodies likewise have a tongue and groove connection on their end faces a recess 1 1 6a is provided on one end face of each molded body, in which the respective radial flanges 1 30a can be received, so that an arrangement of the individual molded bodies 1 6a, 1 8a, 20a directly abutting one another without interference from the radial flanges 1 30a is possible. In order also to avoid interference from the hexagon sections 1 32a, the channels 17a can have such a large diameter that the hexagon sections 1 32a can enter them, or the channels 17a can at least be widened in their end regions so that the hexagon sections enter there 1 32a into channels 1 7a is possible. In this embodiment, the fixing rod pieces are integrally formed or assembled with the hexagonal sections 132a and the radial flanges 130a. The radial flanges 1 30a have a disk configuration, so that the recesses 1 1 6a in the end faces 88a of the shaped bodies 1 6a, 1 8a, 20a also have a corresponding configuration. The springs 106a provided on the end faces 102a are also interrupted in the sections corresponding to the recesses 1 1 6a, in order to prevent interference with the radial flanges 1 30a here as well.

When building a track transition device of the above-described manner, therefore, it starts from the length center region, since it cannot always be avoided that manufacturing tolerances of the moldings and / or during the construction of a track system lead to the division of the moldings in the longitudinal direction not exactly the division corresponds to the thresholds. That is, by arranging a plurality of moldings in succession in the longitudinal direction, such errors resulting from manufacturing inaccuracies can add up, so that there is a risk, in particular in the case of long track transition devices, that the sum of the errors no longer causes the impact between two moldings lies above a threshold. If one starts from the length center area, the accumulation of such errors is distributed to both sides, so that the errors are halved on each side over the entire length of the track transition device and thus the risk of misalignment of the joint or the end of shaped bodies can be avoided with the thresholds. Nevertheless, it is of course possible to work starting from one end when building a track transition device.

As can be seen in FIGS. 11 and 14, the shaped bodies 1 6a have approximately half the extent of the outer shaped bodies 1 8a, 20a in the longitudinal direction. This results in a total of molded articles 1 6a, 1 8a, 20a being obtained which are approximately the same in terms of their overall dimensions and thus on the one hand do not require any particular different transport measures and on the other hand can be produced with the same pressing device. In order to be able to use the same fixing rod pieces 38a for all shaped bodies 1 6a, 1 8a, 20a, as already mentioned, two central shaped bodies 1 6a are combined to form an assembly. It is pointed out that, if this is necessary for structural reasons, separate fixing rod pieces can also be provided for each central molded article, or that more than two molded articles can also be combined to form a correspondingly longer group.

In the embodiment of a track junction device shown in FIGS. 1 1 and the following, as with the embodiment shown with reference to FIGS. 1 to 10, a multiplicity of identical molded bodies 1 6a or 18a, 20a can be used to construct the track junction device; it is not necessary to provide differently shaped bodies, for example for the end regions and the intermediate region. The outer molded bodies 1 8a, 20a can also be mutually be identical and are only arranged with the opposite orientation with respect to one another.

In the embodiment of a track transition device and the fixing rod pieces 38a described above with reference to FIGS. 11 to 14, the radial flanges 1 30a provided on the fixing rod pieces serve either as intermediate contact means 32a or as end contact means 28a, depending on the location of use of the fixing rod pieces. That is, the same fixing rod pieces can be used in the entire length range of the track transition device without structural changes; the specific designation of the radial flanges 1 30a as end contact means 28a or intermediate contact means 32a is given by the respective installation location.

With reference to Figures 1 5 to 22, various configurations of the fixing rod pieces or the intermediate pieces are described below.

Figures 1 5 and 1 6 show an embodiment which essentially corresponds to the embodiment shown in Fig. 1 3. The fixing rod pieces 38a 'each comprise a threaded rod section 230a', which is screwed into the internal thread opening 1 34a 'of an external hexagon section 1 32a' with a first end 231a 'and is welded to the external hexagon section 1 32a' at 233a '.

The flange sections 1 30a 'are formed with a central through opening 238a' and fitted with this over the hexagon section 1 32a 'of a fixing rod piece 38a' or an intermediate piece 138a 'and at 236a' in that shown in FIGS. 1 5 and 1 6 in Longitudinally welded in an asymmetrical manner with respect to the external hexagonal sections 1 32a ', so that the section of the hexagonal section 1 32a' lying on the side of the connection with the threaded rod 230a 'is longer. For connection, the threaded section 1 36a ', i.e. the one there

CORRECTED SHEET (RULE 91)

ISA / EP End of each fixing rod piece 38a ', in the internal thread opening 1 34a' of an immediately following fixing rod piece or an intermediate piece 1 38a 'are screwed, as z. B. is shown in Fig. 1 6. It is pointed out here that due to the asymmetrical arrangement of the radial flanges 1 30a 'shown on the fixing rod piece 38a' or on the intermediate piece 1 38a 'for those fixing rod pieces 38a' which are not for connection to another fixing rod piece 38a but with the intermediate piece 1 38a Shorter threaded rods 230a must be provided, since the longer outer hexagon section area of the intermediate piece 38a, which is located on the right in the illustration in FIG. 1 6, also projects into a channel 17 a. The fixing rod pieces 38a 'provided for connection to other fixing rod pieces 38a' must be at least long enough that their threaded section 1 36a 'is still screwed into the internal thread opening 1 34a' of a subsequent fixing rod piece 38a ', ie the shorter section of the external hexagon section 1 32a' can be. A suitable fixing of the individual fixing rod pieces to one another is thus possible, but it is avoided that, for example, excessively long sections protrude on the last fixing rod pieces 38a 'in the longitudinal direction, which are no longer covered by a molded body.

The radial flanges 1 30a 'each carry fixing projections 234a' which, after being attached to a molded body, engage in a fixing recess 240a 'provided in a respective end face thereof, which, as can be seen in the illustration in FIG. 1 1, on the respective end face 1 02a of the Shaped body (in Fig. 1 1 only recognizable in connection with the outer shaped bodies 1 8a) is provided. The fixing projection 234a 'engaging in the fixing recess 240a' prevents the radial flange 1 30a 'already held between two molded bodies, which together with its associated fixing rod piece 38a' from the outside, not when screwing a subsequent fixing rod piece 38a 'into the internal thread opening 1 34a' is more accessible, turns inadvertently. The provision of the fixing recesses 240a 'is particularly advantageous when the shaped bodies 16a, 18a, 20a are constructed from relatively hard material, for example thermoplastic materials. When the molded body is made of elastic material, the fixing recesses can be omitted and the fixing projections 234a 'can be pressed into the molded body material.

In the embodiment according to FIGS. 17 to 20, each radial flange has an internal polygonal opening, in the illustration an internal hexagonal opening 242a ", which can be formed therein, for example, by stamping or punching. Both sides close on one side of the radial flange 1 30a" in the case of the fixing rod pieces 38a "and the intermediate pieces 1 38a", an internal thread section 244a ", which has the internal thread opening 1 34a". The internal thread section 244a "can be formed, for example, by a conventional nut part with a correspondingly dimensioned thread size and can be fixed to the radial flange by welding or the like. The internal thread section is followed by a threadless pipe section 246a" for each fixing rod piece 38a "and for each intermediate piece 1 38a", which is essentially firmly connected to the first internal thread section 244a "essentially concentrically, for example by welding or the like. For each fixing rod piece 38a", the threaded rod 230a "is inserted into the pipe section _46a" and fixed therein, for example by welding. For each intermediate piece 1 38a ", a second internal thread section 248a" is fixed to the pipe section 246a ", for example by welding and concentrically to it. Each second internal thread section 248a" can in turn be formed by a conventional nut part and has an internal thread opening 1 34a "for screwing in a threaded rod 230a ". In this embodiment, too, due to the asymmetrical design, it must be taken into account that those fixing rod pieces 38a "which are to be coupled with an intermediate piece 1 38a" are to be made shorter in the longitudinal direction, since the Pipe section 246a "with the internally threaded sections 244a" and 248a "of the intermediate piece 1 38a" already protrudes into a channel 17a. The length of those fixing rod pieces 38a "which are intended for connection to another fixing rod piece 38a", ie which are to be screwed into the internal thread section 244a "of another fixing rod piece 38a", must be designed in such a way that they are inserted after insertion protrude into a channel of a molded body with its externally threaded sections 1 36a "in the region of their free ends beyond the molded body and can be screwed into the internally threaded section 244a" of a subsequent or preceding fixing rod piece 38a ". Here, too, the radial flanges 1 30a" again have the fixing projections 234a " to prevent, as described above, an unintentional turning of a fixing rod piece 38a "or intermediate piece when screwing in another fixing rod piece 38a". In this embodiment, the fixing rod pieces 38a "and the intermediate piece 1 38a" are inserted by inserting an external polygonal key, for example an Allen key, is turned into the polygonal opening 242a ".

The embodiment shown in FIGS. 1 to 20 has the advantage that the internal thread sections 244a ", 248a" are only relatively short and therefore conventional nut parts can be used which are to be connected to one another by the pipe section 246a ". The provision of continuous Internal thread sections corresponding to the external hexagon sections, as is the case in the embodiment forms according to FIGS. 1 5 and 1 6, are therefore not necessary here, and nevertheless the required screwing depth of the external thread sections 1 36 a "can be achieved.

Embodiments of fixation rod pieces that are designed for insertion into channels that are closed all round have been described above. FIG. 21 shows an embodiment which is particularly suitable in connection with a channel which is open, for example, to an underside of the molded body, as is the case with the embodiment according to FIGS. 1 to 10. The structure again corresponds essentially to the structure shown in FIGS. 19 and 20 with an internally threaded section 244a '"and a pipe section 246a'" into which the threaded rod 230a '"is inserted and then fixed, for example by welding. The radial shown above flange 130a "is replaced here by a plate part 250a '" which is fitted over the pipe section 246a'"and abuts a radial shoulder 252a '" which is in the transition region between the pipe section 246a'"and the inner part formed, for example, by a conventional nut a radial projection 254a '", for example a ring or the like, is fixed to the tube section 246a'" by welding, locking action or the like in order to prevent an axial displacement of the plate part 250a '". As can be seen in FIG. 21, the plate part 250a '"is asymmetrical, ie the through opening 254a'" is shifted to one side, ie to the underside. This is necessary since, when attached to a channel of a molded body which is open at the bottom, the entire fixing rod pieces are displaced downward and in particular the butt and connecting areas between individual fixing rod pieces are above thresholds, so that little space is available towards the bottom. At the top, however, if the recesses are designed accordingly, there is sufficient installation space in the end faces of the shaped bodies, as has been shown above with reference to the embodiment of FIGS. 1 to 10. Since, due to this asymmetrical configuration, the plate part 250a '"cannot be rotated when the fixing rod piece 38a'" is screwed in, the plate part 250a '"is rotatably held on the pipe section 246a'". The plate part 250a '"can have, for example, a rectangular shape or any other suitable shape, in which case the recesses provided in the end faces of the shaped bodies have a corresponding shape. It is pointed out that the intermediate pieces provided for the embodiment of FIG. 21 can be constructed in a corresponding manner, ie at the end of the tube section 246a '"to which the threaded rod 230a'" is attached in the illustration in FIG. 21 a second female thread portion is provided as shown in FIG. 20. It is further pointed out that various other configurations for axially fixing the plate part 250a '"to the fixing rod piece 38a'" or to each intermediate piece can be provided. For example, it is possible to make the pipe section 246a '"so short that the plate part 250a'" is held between two internal thread sections 244a '"to be arranged on both sides of the pipe section 246a'". Furthermore, it is possible to support the plate part 250a "only on one shoulder, for example the shoulder 252a", and on the other axial side there are no provisions, such as the radial projection 254a ", for holding the plate part 250a". The plate part 250a "is then held only by the clamping action between the shoulder and the respective end face of the associated molded body.

It is further pointed out that, although a threaded rod is mentioned above, this threaded rod can also be provided with the externally threaded section 1 36a only in its or its end regions and can be formed without a thread on its other longitudinal sections.

An embodiment of the device, as shown in FIGS. 1 1 to 24, is particularly advantageous if materials such as concrete, steel or the like are used for the shaped bodies. In the case of moldings produced from such materials, it is possible in a simple manner to provide the through openings or channels 17a in the moldings already during the production process. In this case, the through openings 17a are advantageously already arranged in the central height region of the shaped bodies. Then the molded body under tension by the fixing rod 22a held against each other, the occurrence of an evasive movement of the molded body can be counteracted. At the same time, however, it is also possible to provide the through openings 17 a in the areas closer to the underside or the top of the shaped bodies.

Although the device according to the invention is shown in the figures in such a way that a fixing rod 22 or 22a is provided for the outer moldings 1 8, 20 or 1 8a, 20a and two in each for the central moldings 16 or 1 6a laterally spaced fixing rods 22, 22a are provided, it goes without saying that the number of fixing rods provided in each case can be adapted to the special requirements with the associated end contact means and intermediate contact means. A track transition device can also be constructed in such a way that it comprises, in its central region, a structural unit combined by fixing rod means or possibly also several structural units decoupled from or coupled to one another and that further molded bodies are arranged in at least one end region, but these are not due to lower loads need to be coupled to a structural unit using fixing rods. This can be the case, for example, if a pedestrian crossing is created in an end region of a level crossing and a street crossing is created in the central region, in which case the occurrence of significant displacement loads is not to be expected in the pedestrian crossing. Furthermore, each structural unit or each package of moldings or each group of moldings can have a number of moldings adapted to the special requirements, e.g. also have only one shaped body.
