Abstract

A procedure for the positioning of two-block sleepers relative to a rail grid support plate is described. The two-block sleepers (20) comprise two sleeper blocks connected rigidly together by a connection arrangement (24), following each other in a longitudinal direction of the sleepers. The procedure comprises the following steps: - bringing the two-block sleepers into a position relative to the rail grid support plate which corresponds essentially to the installation position of the two-block sleepers; - holding the two-block sleepers in essentially the same position reached above so that with at least one part of the two-block sleepers, at least one sleeper block (22) is supported relative to the rail grid support plate in or near its two opposite end regions in the longitudinal direction.

Description

The present invention relates to a method for positioning Two-block sleepers with respect to a grate support plate, the two-block swell two consecutive in a longitudinal direction and thresholds firmly connected to one another by a connecting arrangement comprise blocks, and a support arrangement for supporting a such a two-block threshold with respect to a track grid support plate.

DE 195 08 107 C1 describes a procedure or a procedure Apparatus known with which a two-block threshold comprehensive Track grid in relation to a trough-shaped track grid support plate provided for the installation of the two-block sleepers in a filled concrete layer Installation position can be brought and can then be held in this. In this known procedure, so-called track regulation portals used, one in the area between each two-block swell under the rails connected with the visual waves Have carrier, which in its end regions in both vertical and in the horizontal direction by respective spindle devices with respect to Track grid support plate is supported. The entire rail grate hangs on this, for example, every second space between two beams intended for block sleepers. Only after the introduction and Hardening the filler concrete material, these supports can be removed and then be used again in another area. The Providing these track regulation portals is very expensive and also leads to the problem that when used in only every second Gap between two-block sleepers of the track grate over comparatively  long areas are not supported and can sag there. This Sagging is especially so when driving over it Railways are then noticeable at high speed. To the Avoiding this problem would ultimately have to be in every space Such a track regulation portal between two two-block sleepers be used, but this leads to a further significant increase in Would lead to costs.

It is the object of the present invention to provide a method for positioning ren of two-block sleepers with respect to a track grid support plate and one Support arrangement for supporting a two-block threshold with respect to Provide track grid support plate with which in a cost-effective manner and Way a defined bracket of such two-block thresholds relation achieved such a two-block sleepers having track grating can be.

According to a first aspect of the present invention, this object is achieved by a method for positioning two-block sleepers with respect to a track support plate, the two-block sleepers comprising two sleeper blocks which are successive in a longitudinal direction of the sleeper and are firmly connected to one another by a connecting arrangement, comprising the steps:

• a) Bring the two-block sleepers into position with respect to the track grate support plate, which is essentially the installation position of the two-block swell corresponds,
• b) Maintaining the two-block sleepers essentially in the same way as in step a) achieved situation in that at least part of the Two-block thresholds at least one threshold block in or near opposed to his two in the longitudinal direction of the threshold lying end areas with respect to the platform support plate becomes.

In contrast to the prior art, the present invention works the way to provide the bracket directly on the two-block sleepers, so that possible sagging or the like cannot occur. Furthermore, the two-block sleepers are on their sleeper blocks supported in such a way that despite the comparatively elastic connection sagging between the individual blocks of a two-block threshold such thresholds in the middle area is avoided. It can be on this Way that the two-block sleepers are exactly in the position brought and held in this position in which they subsequently also to be embedded in a filled concrete layer. It follows a particular advantage if each of the two-block thresholds in such Way is treated. In principle, however, it is also conceivable not all two-block sleepers of a track grate that has already been manufactured or To hold the threshold network in this way.

For example, can be provided in the method according to the invention be that in or near the other threshold block one Two block threshold facing first end area a threshold block by a first support device with respect to the platform support plate is supported and in or near one of the other smoldering lenblock of a two-block threshold facing second end the threshold block is supported by a second support device with respect to the Track grid support plate is supported.

In order to achieve the support with respect to the track grid support plate, suggested that each support device from first and second Support device of a threshold block at least one support member has that for supporting the threshold block with respect to a Bottom area of the platform support plate can be supported.

According to a further particularly advantageous aspect, provision can be made be that at least one support device of the first and second  Support device of a threshold block at least two with respect to the Threshold longitudinal direction arranged at a lateral distance from one another Has support organs. By providing this regarding the Threshold longitudinal direction laterally spaced support members further ensured that a lateral tilting of such supported two-block threshold or one supported in this way Threshold blocks cannot occur. This enables the two-block swell regardless of whether through rails or other Connecting elements to a track grate or sleepers are grouped together to hold with respect to the track grid support plate. The main advantage of this is that when the Filling concrete material to couple each other the two-block sleepers the organs can be removed so that their by thermal Influenced dimensional changes do not lead to an unwanted Displacement of those already adjusted and held in the adjustment position Can lead to two-block sleepers.

Furthermore, it is advantageous if the track grate support plate essentially is designed like a trough with a trough bottom and trough side walls, and if the second support device at least one threshold block has at least one support member which is used to support the Threshold blocks are supported with respect to a trough side wall can.

For an alternative or supplementary to the preceding aspects Embodiment can be provided that on the grate support plate at least one, preferably assigned to each two-block threshold Abutment arrangement is provided, which in the longitudinal direction of the threshold positioned between the two threshold blocks of the two-block threshold or is to be positioned, and that at least one, preferably both Threshold blocks of the two-block threshold by a third support device on the abutment arrangement essentially in the longitudinal direction of the sleeper  is supported. Such a configuration is particularly of Advantage if a non-trough-shaped plate is formed as the track grid support plate over which the individual thresholds are then to be positioned, but ultimately an approximately flat one without side restrictions Zungwandungen formed plate is formed. Through the in thresholds longitudinal direction between the individual threshold blocks Support can be used in this direction for a defined bracket Two-block clamps are taken care of.

In this embodiment too, it can be provided that the third Support device assigned to the at least one threshold block at least one regarding the threshold block and the abutments arrangement has supporting support member.

A very simple and inexpensive to build, which also a very precise and easy adjustment of the bracket position allows, that at least one of the support members a support spindle provided at least in some areas with an external thread includes.

Furthermore, it can be provided in the method according to the invention that step a) comprises the following measures:

• 1. a ₁ ) laying a plurality of two-block sleepers on the platform support plate,
• 2. a ₂ ) connecting the two-block sleepers with connecting members, preferably rails, to obtain a tie assembly,
• 3. a ₃ ) Adjusting the position of the threshold assembly in order to essentially maintain the installation position.

It is then further advantageous if the method comprises the following further steps after step b):

• a) removing the connecting members from the two-block sleepers,  
• b) pouring the two-block sleepers with filling concrete,
• c) after the filling concrete has hardened, attaching rails to the Two-block sleepers.

As previously stated, removing the Connecting elements, which can also be rails, for example, and the installation of the rails to complete the railroad track first after the filling concrete has hardened, ensure that the defines individual thresholds in the position in which they are adjusted have been held. This also makes it possible, for example Procedure in which first the two-block thresholds in their Installation position brought and held in this and then to Adjust still inserted rails or connecting elements in one other area can be used, so that ultimately an in its longitudinal direction is significantly longer than the individual rails or Linkage trained section with adjusted sleepers can be obtained, which can then be used in one operation Filling concrete can be poured.

To at least after pouring the thresholds with filling concrete material slight setting of the thresholds in this material during hardening enable, it is proposed that after step d) and before a complete interaction of the filling concrete at least part of the support devices at least partially will be annulled.

In an alternative embodiment, it can be provided that the method comprises the following further steps after step b):

• a) before or after removing the two-block sleepers into one Liaison bodies summarizing the threshold association, preferably rails, at least partially filling the between an underside of the threshold blocks of the two-block sleepers  that held in the position reached in step a) Threshold composite and the top of the track support plate formed space with a relining material, preferably concrete material,
• b) after the relining has at least partially hardened materials at least partially, preferably essentially completely remove the support devices and remove if necessary the connecting organs,
• c) Pouring the two-block sleepers with filling concrete.

A major advantage of this type of design is that even before Introduction of the filled concrete layer to the various support devices can be at least partially removed as the more extensive Hold the individual two-block sleepers or sleeper blocks the same is done by the hardened relining material. Next to the Advantage that no materials susceptible to corrosion then in the filling concrete have to be integrated, there is the essential further advantage, that the various support devices are used again can, so that a significantly cheaper production can take place.

According to a further aspect of the present invention, the object mentioned is achieved by a support arrangement for supporting a two-block sleeper with respect to a track supporting plate, the two-block sleeper comprising two sleeper blocks which follow one another in a longitudinal direction of the sleeper and are firmly connected to one another by a connecting arrangement, the bracing arrangement for at least a threshold block of the two-block threshold comprises:

• - A first support device for supporting the threshold block with respect to the grate support plate in or near a first end realm of the same, which in the longitudinal direction of the threshold to the other Threshold block is positioned facing the two-block threshold,  
• - A second support device for supporting the threshold block with respect to the platform support plate in or near a second End portion of the same, which in the longitudinal direction of the threshold facing away from the other threshold block of the two-block threshold is positioned.

As already mentioned at the beginning, such a support arrangement has which respective threshold blocks are supported in their two end areas, the main advantage that even within the individual thresholds no deformations can occur even after adjustment.

For example, it can be provided that the first support device at least one on the threshold block in the first end region or / and supporting on the connection arrangement near the first end region, preferably attached to it and at least one with the supporting element is coupled or can be coupled in a positionally variable manner and provided for support with respect to the platform support plate Has support member.

It is also advantageous if the second support device at least one on the threshold block in the second end region and / or on one protruding from the second threshold block in the second end region Support arrangement supporting, preferably attached to it Support element and at least one position ver with the support element changeably coupled or connectable and for support with respect to the Track grate support plate provided support member.

The above-mentioned embedding of the sleepers in fill concrete material without the presence of connecting elements or To allow rails on these, it is suggested that at least a support device of the first support device and the second Support device, preferably the second support device, at least  two laterally spaced with respect to the longitudinal direction of the sleeper mutually arranged support members for supporting the sleeper block with respect to a bottom region of the track grating support plate.

According to a particularly advantageous aspect of the present invention can be provided that the first and the second support device on an essentially the assigned threshold block completely surrounding support frame are provided. This support frame can then further form a formwork, which one between the Threshold block and a surface of the platform support plate formed Space surrounds. With this arrangement, you can easily do it be made sure that after adjusting a two-block threshold this with Relining material is fixed with respect to the track grid support plate and so is held in a defined manner without a support arrangement here would be required. The provision of additional formwork is then not mandatory.

At least one filling opening for is preferably on the support frame relining material to be introduced into the space, preferably wise concrete material, provided. In particular after fixing a Two-block threshold through the relining material removing the To support frame or the support arrangement in a simple manner Chen, it is proposed that the support frame a plurality of detachable comprises interconnectable frame elements.

A defined lateral hold of the individual two-block sleepers, i.e. H. laterally based on a longitudinal direction of the rail track to be produced, can can be obtained in that the second support device at least one for supporting the threshold block with respect to a side wall of the Track grate support plate provided support member.  

To obtain the simplest possible structure, it is advantageous if the at least one for supporting the threshold block with respect to one Side wall of the track grate support plate provided with a support Support element of the second support device can be changed in position is coupled or can be coupled.

Furthermore, it is preferred in the support arrangement according to the invention provided that the at least one for supporting the threshold block provided with respect to a side wall of the grate support plate Support member and at least one for supporting the threshold block provided with respect to a bottom region of the platform support plate Support member of the second support device with the same, preferably angled support element of the second support device positionally coupled or can be coupled.

It can further be provided that the support arrangement has a third Support device comprises at least one threshold for supporting blocks of a two-block threshold with respect to one in the threshold lengthways direction between the two threshold blocks of the two-block threshold positioned or to be positioned abutment arrangement essentially lichen in the longitudinal direction of the threshold. As already stated, also regardless of whether laterally bounding trough walls on the Track grid support plate are provided, a support in the sleeper lengthways direction.

Again, it is advantageous if the third support device is on support element provided for support on the abutment arrangement comprises little and associated with the at least one threshold block Mostly a support member that can be moved with the support element is coupled or can be coupled.  

To define a defined in both orientations of the longitudinal direction of the threshold To be able to obtain a holder, it is proposed that the support element in the longitudinal direction of the sleeper at its two end regions each with at least one support member for supporting this Threshold blocks near the end area of the two-block threshold positionally coupled or can be coupled.

Since it cannot always be guaranteed that for different Two-block sleepers used abutment arrangements exactly the same Have dimensions, in particular for reusability of the third support proposed that the support element at least in the longitudinal direction of the threshold to the dimension of the counter bearing arrangement is customizable. This can be achieved, for example be that the support element two telescoping with respect to each other has displaceable support element areas.

This makes it very easy to manufacture and operate be obtained that at least one of the support members at least one includes a support spindle provided in some areas with an external thread, and that for the positionally variable coupling of the support spindle with a associated support element this one provided with an internal thread Has opening.

Since in the support arrangement according to the invention at least part of the Components of the same in the surrounding the individual thresholds Filling concrete layer is embedded, to avoid corrosion conditional damage suggested that the first prop or / and the second support device or / and the third support device at least in some areas corrosion on its surface resistant material, is preferably galvanized, and / or from such material is formed.  

It can further be provided that the connection arrangement or / and if necessary, the support arrangement as reinforcement in a respective Threshold block of the two-block threshold is integrated.

In another aspect, the present invention relates to a fixed one Railroad track, comprising one in a longitudinal direction of the roadway extending concrete slab, a plurality of along the road Direction successively arranged over the concrete slab or to be arranged two-block thresholds, each two-block threshold two in a threshold longitudinal direction provided at a distance from one another and by a connection arrangement firmly interconnected threshold blocks has, and at least one of the two-block thresholds assigned one the concrete slab provided and over the top in one area protruding first reinforcement arrangement, which area at over the Concrete slab positioned two-block sleeper in the sleeper lengthways direction between the two threshold blocks of the two-block threshold lies.

The provision of such over the top of the concrete slab protruding first reinforcement arrangement especially in the area between the individual areas of a two-block threshold has the advantage that in the area where there is a relatively large load is a dense reinforcement network, essentially formed from the first reinforcement arrangement and also a reinforcement of a Filling concrete layer connecting arrangement of the two-block threshold, is achieved.

This effect of creating a tight reinforcement composite can reinforced by the fact that the first reinforcement arrangement in a space between the two threshold blocks assigned engages two-block threshold. It is also advantageous if the Connection arrangement of the two-block threshold at least two laterally  Threshold longitudinal direction spaced connection has arrangement areas, and if the first reinforcement arrangement engages between the two connection arrangement areas.

With such an arrangement, it is further advantageous if at least one is essentially in the longitudinal direction of the road extending longitudinal reinforcement element is provided, through which the Connection arrangement and the first reinforcement arrangement with each other are coupled. Ultimately, this longitudinal reinforcement element can then through the connection arrangement or the first reinforcement arrangement be pushed through, so that for example in one direction away from the top of the concrete slab and along the threshold direction a positive interaction between these individuals Total reinforcement contributing elements or areas is generated.

To make it very easy to manufacture and at the same time safe-looking To receive reinforcement, it is proposed that the first reinforcement arrangement for the two-block sleeper in his over the concrete support plate protruding area essentially U-shaped reinforcement element includes with two U-legs and connected to the concrete slab one is preferably essentially transverse to the longitudinal direction of the carriageway extending web section and connecting the two U-legs. Around the connection between the sleepers, a filling concrete layer and the Concrete slab to improve even further, it is suggested that at least one of the threshold blocks on that of the other threshold block distant end portion at least one coupling element protrudes, and that at least one on the concrete support plate Coupling element assigned a second reinforcement arrangement is seen, which in an installation position in regions above the at least is a coupling element. Again, it is possible that the second reinforcement arrangement for the at least one coupling element of the at least one threshold block in its over the top of the  Concrete support plate protruding area essentially U-shaped Reinforcement element with two preferably essentially in driving web longitudinal direction spaced U-legs and comprises a web section connecting the U-legs.

Such concrete slabs are used in various stages of manufacture for example, by trucks. One of those manufacturing stages is, for example, the separation of the individual two-block thresholds on or above the concrete slab. The one with the outside areas of the Two-block sleepers interacting second reinforcement arrangements or reinforcement elements of the same often lie in one area, on which the wheels of the trucks then roll. To do one undefined deformation or damage to these reinforcement elements to avoid second reinforcement arrangements, it is proposed that before placing a two-block sleeper over the concrete slab at least the second movement assigned to one of the threshold blocks arrangement with her over the top of the concrete slab protruding area in a substantially to the top of the Concrete base plate approximate preparation position is located. this makes possible furthermore the simple application of the two-block sleepers and after following, for example, the bending up of the individual reinforcement elements of the second reinforcement assemblies so that they can then face the outside overlap protruding coupling elements of the two-block sleepers.

As already indicated, in the fixed rails according to the invention roadway a filling concrete layer can be provided, which the two-block surrounding the threshold in certain areas and into which the connection arrangement, the first reinforcement arrangement and, if applicable, the second reinforcement arrangement are embedded.

According to a further aspect, the present invention relates to a method for constructing a fixed rail track, the fixed rail track having a concrete support plate and a plurality of two-block sleepers arranged or to be arranged successively above the concrete support plate in a longitudinal direction, each two-block sleeper spaced apart in a longitudinal direction of the sleeper Threshold blocks provided and firmly connected to one another by a connection arrangement, comprising the steps:

• a) manufacturing the concrete slab,
• b) for at least one two-block threshold provide one over a Top of the concrete slab protruding first reinforcement arrangement in an area that is above the concrete slab positioned two-block sleeper in the longitudinal direction of the sleeper lies between the two threshold blocks, if necessary
• c) provide for at least one two-block threshold one over the Top of the concrete slab protruding second reinforcement arrangement in an area that is above the concrete slab positioned two-block sleeper in the longitudinal direction of the sleeper an end region remote from the other threshold block from one of the threshold blocks,
• d) Positioning and aligning the two-block sleepers over the Concrete slab,
• e) Casting around the two-block sleepers, the first reinforcement arrangement and optionally the second reinforcement arrangement with material for a filled concrete layer.

By providing method step n) and only optional The proposed process step o) can, as already mentioned above executed, a defined fixed reinforcement network, especially in those areas are created in which high loads occur. Furthermore, providing the first reinforcement arrangement tion or the first reinforcement arrangements discussed above Advantage that the two-block sleepers adhere to these when adjusting  can support the first reinforcement arrangements and thus in a defined Can be held without necessarily moving up to have to provide standing side walls on the concrete support plate.

The coupling of different reinforcement elements of the different Reinforcement arrangements with the concrete slab can, for example in that step n) and / or optionally step o) the introduction of a respective reinforcement element of the first reinforcement arrangement or the second reinforcement arrangement in the not yet cured material of the concrete support plate comprises. It was nevertheless on it noted that, of course, in part or in full cured material of the concrete base plate holes are drilled into which leg sections of the reinforcement elements used and determined for example by pouring material can.

Furthermore, the method according to the invention can be carried out after step p) and before step q) the introduction of at least one of the first reinforcement arrangement voltage and the connection arrangement of at least one two-block threshold comprise coupling longitudinal reinforcement element.

As already stated, it is advantageous if step o) provides of the second reinforcement arrangement in a preparation position, and if the procedure after step p) and before step q) bringing the second reinforcement arrangement into one with an area thereof at least one coupling element of a two-block threshold Installation position includes.

The present invention will hereinafter be described with reference to the accompanying Drawings in detail based on preferred embodiments described. It shows:

In Figs. 1 to 4 a rail track shown in part generally indicated with 10. This rail track 10 comprises a track grate support plate 12 , which is designed with a trough shape in the illustrated embodiment. The track grid support plate 12 thus comprises a trough bottom 14 and on both side end portions of each trough cheeks or Trogwandungen 16 which slope down obliquely at their mutually facing side surfaces 18 to the trough bottom 14, so that in the direction towards the trough base 14 toward the lateral spacing between the mutually facing opposed fitting surfaces 18 of the trough walls 16 decreases. The railroad track 10 further comprises a plurality of sleepers 20 arranged one after the other in the longitudinal direction thereof. These thresholds 20 are designed as so-called two-block thresholds, which have two threshold blocks 22 in succession in a longitudinal direction L of the threshold. The two threshold blocks 22 are firmly connected to one another by a connection arrangement 24 . This connection arrangement 24 comprises, for example, two so-called lattice baskets 26 , 28 located at a lateral distance - with respect to the longitudinal direction L of the sleeper. Each of these mesh baskets has on its top a in the longitudinal direction L extending the reinforcing element 30 , and has on its underside two spaced and also in the longitudinal direction L extending reinforcing elements 32 , 34 . Each of the reinforcement elements 32 , 34 is connected to the reinforcement element 30 by a reinforcement bracket or a plurality of such reinforcement brackets 36 or 38, respectively. These reinforcement brackets 36 and 38 run, as can be seen in particular in FIG. 1, in a zigzag or undulating manner between the reinforcement element 30 and the reinforcement element 32 or 34. It can also be seen in FIGS. 1 and 4 that the two lower reinforcement elements 32, from the threshold blocks 22 exit 34 not only from their faces lying in each other's threshold block of the same threshold 20 first end region 40 to produce there ultimately the connection to each other threshold-block 22, but also from the sleepers blocks 22 in the of the respective emerge from other threshold block 22 facing away second end region 42 . In this area, the reinforcement elements 32 , 34 or the connection arrangement 24 comprising them form a support arrangement 44, which will be described below.

It can be seen in FIG. 1 that the connection arrangement 24 comprising the reinforcement cages 26 , 28 is integrated into the individual swell blocks 22 in their lower region and thus protrudes in the end regions 40 , 42 in such a way that a subsequently introduced filler concrete material projects beyond the swell blocks 22 Sections of the reinforcement cages 26 , 28 surrounds and thus produce a firm bond between the sleepers 20 and the filler concrete layer and thus towards the platform support plate 12 .

It should be noted that the reinforcement of the sleeper blocks 22 forming reinforcement cages 26, 28 in this smoldering lenblöcke 22 more reinforcing elements are cast 46 additionally stable to configure this in the entire volume range.

The rails 50 can then be fixed to the top of the individual sleeper blocks by fastening arrangements 48 known per se.

When building such a railroad track 10 , the procedure is generally such that the sleepers are first deposited in succession on the trough floor 12 in the longitudinal direction of the railroad track approximately in succession by appropriate work tools, for example with intermediate storage of support elements 52 , which may be made of wood they must subsequently also be installed in the roadway. Subsequently, the sleepers 20 lying one after the other in the longitudinal direction of the railroad track are connected to one another to form a tie assembly. For this purpose, for example, the rails 50 can be used, which should subsequently also remain on the finished rail track 10 , or other, for example, tubular connecting members can be used in order to obtain such a track grate or threshold composite. If such a track grate or threshold composite is produced, it can then be lifted from the support elements 52 by an adjustment arrangement and brought into the intended installation position with respect to the track grate support plate 12 . For this purpose, for example, adjusting devices moving on the trough side walls 16 can be used; but it can also be used for example on the rails or the connecting elements attacking Justierein devices that are supported to the track support plate 12 . If such an adjustment is then carried out in a length range of the rail track 10 to be produced, the individual sleepers 20 are held in this position approximately corresponding to the installation position by a support arrangement 54 described in detail below.

It can be seen in particular in FIG. 1 that the support arrangement 54 has a first support device 56 and a second support device 58 for each sleeper block 22 . The first support 56 lies in or near the end region 40 of the threshold block 22 , whereas the second support 58 is positioned in or near the second end region 42 thereof.

The first support device 56 comprises a plate-like support element 60 , which is arranged on the underside of the adjacent reinforcement elements 34 and 32 of the various reinforcement cages 26 and 28 and is also welded to the threshold block 22 in the longitudinal direction L, for example.

In its section lying between the two reinforcement cages 26 , 28 , this plate-like support element 60 has an internal thread opening 62 , into which a screw spindle 64 serving as a support member of the support device 56 is screwed. This screw spindle 64 has an external thread 66 in a length range thereof. In order to minimize the work required for screwing in the screw spindle 64 , the external thread region 66 is limited to a length range, which is subsequently also used to adjust the mounting position or to make an adjustment.

The second support device 58 also has a plate-like support element 68 which extends transversely to the longitudinal direction L of the sleepers 20 over the reinforcement elements 32 , 34 of the two reinforcement cages 26 , 28 in the area forming the support arrangement 44 and is arranged on the underside thereof . Here, too, it is again possible, for example, to weld this plate-like support element 68 to the threshold block 22 in the end region 42 of the reinforcement elements 32 , 34 . As with the support element 60 of the support device 56, this can be carried out after the two-block sleepers 20 have been produced, which are in any case cast in an upside-down manner, so that after the casting and the at least partial hardening of the concrete material thereof, the support elements 60 , 68 only have to be placed on the underside of the reinforcement elements 32 , 34 lying upwards and have to be welded to them.

Between the reinforcement elements 32 , 34 of the individual reinforcement baskets 26 , 28 , the support element 68 has two internal thread openings 70 , 72 that are laterally spaced with respect to the thresholds longitudinal direction L, into which screw spindles 74 , 76 again serve as support members, with a respective external thread section 78 , 80 are screwed in. Here too, in order to reduce the screwing work required, the external thread section 78 or 80 can be limited to the length range actually required for this.

The support element 68 of the second support device 58 also has a nut 82 which is upright there and provided in a region between the two reinforcement cages 28 , 26 and which, in this positioning, can be welded to the plate-like support element 68, for example. In this nut 82 , a further screw spindle 84, serving as a support member, is screwed with its external thread section 86 in the lateral direction. As can be seen in Fig. 1, the screw spindles 64 , 74 , 76 of the first and the second support device 56 , 58 serve to support the sleepers 20 or a respective sleeper block 22 thereof with respect to the trough bottom 14 of the track support plate 12 , whereas the screw spindle 84 the second support device 58 is used for lateral support of the sleepers 20 or this sleepers block 22 with respect to the opposite side wall 16 of the track support plate 12 .

If a track grate or threshold assembly has been adjusted into the intended installation position, the individual sleeper blocks 22 of the various two-block sleepers 20 of this assembly can be supported with respect to the track grate support plate 12 by turning the various screw spindles 64 , 74 , 76 , 84 in such a way that they are defined in the installation position now provided. Since previously the thresholds have been lying 20 on the supporting elements 52 to be provided in the adjustment displacement of the sleepers 20 is minimized so that the required screwing work can be reduced.

In principle, it should also be pointed out that the adjustment process can also be carried out or at least supported using the support devices 56 , 58 .

If the screw spindles 64 , 74 , 76 , 84 of the various sleeper blocks 22 of the individual two-block sleepers 20 are tightened in such a way that they bear tightly against the associated sections of the track support plate 12 , then the rails 50 or other connecting members in the fastening devices 48 can be loosened, can preferably also be removed. The individual sleepers 20 are secured, in particular by the two screw spindles 74 , 76 that are laterally spaced with respect to the longitudinal sleepers direction L, and also prevent them from tilting sideways - with respect to the longitudinal sleepers direction L.

The subsequent procedure for introducing the Füllbetonma terials can thus be carried out completely unimpeded by rails or other connecting elements. It is also possible to insert a reinforcement 90 formed from longitudinal reinforcement elements 86 and transverse reinforcement elements 88 for the filled concrete layer unimpeded before the introduction of the filler concrete material into the area between the individual sleepers 20 of the trough-shaped track support slab 20 . In particular, the longitudinal reinforcement elements 86 can be supported on the sections of the reinforcement cages 26 , 28 projecting beyond the threshold blocks 22 or can be threaded into these.

Before the filling concrete material has completely hardened, the screw spindles 64 , 74 , 76 are preferably loosened by turning their spindle heads, ie their supporting interaction with the trough bottom 14 is eliminated. For this purpose, as can be seen above all in FIG. 1, the screw spindles 64 , 74 , 76 can have a length such that they protrude beyond the upper edge region of the trough side walls 16 and thus over the upper surface of the filling concrete layer. Before or after the material of the filled concrete layer has completely hardened, these screw spindles 64 , 74 , 76 are then completely removed by further screwing, the partial formation of the same with external thread sections 66 and 78, 80 also having an advantageous effect here. The openings left behind are subsequently filled with pouring material in order to prevent water from penetrating.

The screw spindles 64 , 74 , 76 which are supported to the trough bottom 14 can also be designed with a significantly shorter length, so that they do not protrude beyond the surface of the filling concrete material. However, before the filling concrete material is introduced into the respective screw spindles 64 , 74 , 76 , which are to be loosened subsequently, tubular plug-in tools designed to interact with the spindle heads or tool engagement arrangements and which then move upward over the surface of the filling concrete material survive and can be rotated. These socket-like tools can then be removed so that the screw spindles operated with them remain in the material of the filling concrete layer. In the end, only the areas that are open at the top are filled with pouring material.

Since, as can be seen from the preceding description, the first and second support devices 56 , 58 , or at least parts thereof, are embedded in the material of the filling concrete layer, it is advantageous to coat them with a corrosion-resistant coating, for example to galvanize them, or in some other way How to design corrosion-resistant on their surface.

If the material of the filling concrete layer is then hardened, ie if the supporting structure for the rails 50 is finally completed, these rails 50 can then be mounted on the individual sleeper blocks 22 again. The possibility of being able to introduce the filler concrete material without having to resort to a support effect of the rails 50 for the individual sleepers 20 has the further significant advantage that there is no risk that the filler material to be run over afterwards when the filler material is introduced Rails are contaminated and have to be cleaned again in a complex manner or have to be covered to avoid such contamination.

It should be noted that, of course, variations can be made in the various support devices 56 , 58 . Thus, instead of the nut 82 of the second support device 58, a pipe section provided with an internal thread could be provided. Also be of course a plurality of such be provided to the Trogwän the 16 towards support for caring screw spindles 84 in the lateral direction. Of course, the number of screw spindles supporting the trough bottom 14 can also be changed. In the case of the first support device 56, it can also be ensured that tilting of the sleepers 20 is prevented by a plurality of support spindles lying at a lateral distance from the longitudinal direction L of the sleepers. Of course, conventionally designed, fully threaded screws can be used instead of the screw spindles shown. The support elements of the first and second support devices 56 , 58 could in principle also be embedded in the material of the individual sleeper blocks, for example be cast into this and spindles for interaction with the screw or be exposed in corresponding recesses in the sleeper blocks 22 .

Furthermore, it should be pointed out that a support arrangement 54 according to the invention is advantageously used for all sleepers to be adjusted, even if these sleepers are coupled to one another by rails or other connecting elements when the filler concrete material is introduced. Sagging of the track grate between individual support areas can thus be avoided.

In order not to impede the setting of the individual sleepers 20 , which is made possible by the action on the screw spindles 64 , 74 , 76 which provide support for the trough bottom 14 , by the screw spindles 84 which support the trough walls 16 , it is further possible to adjust them Loosening of the filler concrete material no longer accessible screw spindles 84 immediately before the introduction of the filler concrete material to loosen, ie with their heads from the surfaces 18 at least slightly because of. This is particularly advantageous if the surfaces 18 of the trough side walls 16 are inclined.

A modification of the embodiment shown in FIGS. 1 to 4 is shown in FIG. 5. There is a difference here especially in the area of the second support device 58 . The support element provided there 68 is formed with an angular profile, and now has in a first angle leg 100 the internal thread openings 70 , 72 for the vertical spindles 74 , 76 supporting towards the trough bottom 14 , and then has an internal thread opening in an approximately vertically oriented leg 102 104 for the horizontal spindle 84 . This angular support element 68 can be welded to the reinforcement elements 32 , 34 of the various reinforcement cages 26 , 28 . It should be noted, however, that in the embodiment shown in FIG. 5, as in the embodiment described above, these support elements 60 , 68 do not have to be fixed to the various reinforcement elements 32 , 34 , but rather, for example, only after they have been put down or after Adjustment of the various sleepers 20 can be applied to the underside of these reinforcement elements. When fixed, however, these support elements 68 , 60 together with the various screw spindles 64 , 74 , 76 , 84 and the sleepers 20 can form pre-assembled assemblies.

It should also be pointed out that in the embodiments shown, the second support device 58 does not necessarily have to cooperate with protruding sections of the reinforcement elements 34 , 32 . The support arrangement 44 could in principle also be formed by separate reinforcement or support elements integrated into the threshold blocks 22 .

With reference to FIGS. 6-10, an alternative or further embodiment of the support arrangement, generally designated 54, is described below, or an alternative embodiment of a fixed rail track is described. With regard to the support arrangement 54, it should first be stated that, with regard to the configuration of the support devices 56 , 58 at the two end regions 40 , 42 of the sleeper blocks 22 of the two-block sleepers 20 , they essentially correspond to the embodiments described above, with the difference that in the case of the Only the second support device 58 positioned on the outside is provided with the screw spindles 74 , 76 which support downwards and form respective support members and which engage in screw engagement with a respective plate-like support element 68 . The screw spindles 84 , which are supported to the side, with the associated internal thread members on the plate-like support elements 68 are no longer present. Furthermore, it should be pointed out that, as can be seen in particular in FIG. 7, two screw spindles 64 , 64 ′, which are located at a lateral distance, are also provided in the first supporting device 56 in order to better protect the individual two-block sleepers 20 against lateral tipping. This could also be the case with the embodiments described above.

It can be seen in particular in FIG. 6 that the track grating support plate designed as a concrete support plate with the reinforcement 100 provided therein, formed from longitudinal and transverse reinforcement elements, is essentially in a flat configuration and no longer has the trough side walls. That is, the track grating support plate 12 is now, for example, formed on the hydraulically bound support layer 102 as an essentially flat concrete support plate. In this way, the disadvantage of the accumulation of water which has penetrated into a trough-like slab support plate can be avoided in different areas.

In order nevertheless to be able to obtain support in the longitudinal direction L of the threshold, i.e. essentially transverse to the longitudinal direction R of the road, which is essentially orthogonal to the plane of the drawing in FIG. 6, in the adjustment and mounting of the individual two-block sleepers 20 , it can be seen in FIG. 6 Track support plate 12 preferably for each two-block sleeper 20 a generally designated 104 reinforcement element is provided, which can be formed for example from a U-shaped reinforcing steel. This reinforcement element 104 is fixed in the track support plate 12 with its two U-legs 106 , 108 , which are spaced apart from one another in the longitudinal direction L of the threshold and are connected to one another by a web section 110 . This can be done, for example, by shaking the reinforcement elements 104 into the desired position after the material of the track support plate 12 has been removed and before it has fully hardened, for example until they stand on the hydraulically bound support plate 102 with their U-legs 106 , 108 . Nevertheless, a hole could be drilled into the hardened track support plate 112 for each U-leg 106 , 108 and then the associated U-leg could be inserted into this hole and fixed therein with filler material. These reinforcement elements 104 , which ultimately form a first reinforcement arrangement for each of the two-block sleepers 20 , are provided in the track support plate 112 in such a way that they lie in a region which, after the separation of the two-block sleepers 20, lies in the longitudinal direction L of the sleeper between the individual sleeper blocks 22 . Furthermore, the reinforcement elements 104, with their section projecting above the upper surface 112 of the track grate support plate 12, engage in the space region formed between the two sleeper blocks 22 , preferably between the individual reinforcement cages 26 , 28 or respective reinforcement elements 32 , 34 thereof.

To adjust or hold the individual two-block sleepers 20 by means of the first or second support devices 56 , 58 essentially in the vertical direction, the procedure is as described above. A third support device 114 is provided for support or mounting in the longitudinal direction L of the sleeper, ie essentially transversely to the longitudinal direction R of the roadway, for each two-block sleeper 20 to be held or adjusted in this way. Such a third support device 114 is shown in more detail in FIG. 8. It can be seen that the third support device 114 has a support element 116 which is essentially formed from two rod or tube sections 118 , 120 which can be pushed into one another or telescoped with respect to one another, on each of which an angle receiving element 122 or 124 is fixed, for example, by welding. The reinforcement element 104, with its corner or angle regions, can enter these angle receiving elements 122 , 124 in the transition between the U-legs 106 , 108 and the web section 110 . By moving the two rod sections 118 , 120 with respect to each other, the angle receiving elements 122 , 124 can be brought into contact with the outside and also the top of the reinforcement element 104 . A length adjustment of the support element 116 of the third support device 114 to reinforcement elements 104 that differ in their dimensions can thus be easily carried out.

At the spaced-apart end sections of the rod or tube elements 118 , 120 , respective nut elements 126 , 128 are supported , into which screw spindles 130 , 132 forming support members are or can be screwed. The screw spindles 130 , 132 are then supported, for example, via tapered or rounded head regions 134 , 136 on the end regions 40 of the sleeper blocks 22 . The tapered or rounded profile prevents the screw spindles 32 from running away laterally when the screw spindles 32 are turned . For support in the sleeper longitudinal direction L, are thus either before or after the thresholds have been designed such that they lie with their two reinforcement cages 26, 28 on both sides of the reinforcing member 104, the third supporting means placed on these reinforcing elements 104 114th By turning the screw spindles 130 , 132 , they can then be brought into contact with the sleeper blocks 22 and thus the sleepers 20 as a whole can be shifted and fixed in the longitudinal direction L of the sleeper. During this rotation of the screw spindles 130 , 132 , the two rod or tube elements 118 , 120 are then automatically shifted with respect to one another in such a way that the angle receiving elements 122 , 124 lie against the U-legs 106 , 108 of the reinforcement element 104 and thus a length adjustment of the support element 116 occurs on the respective reinforcement element 104 .

It should be pointed out here that, for example, the nut elements 126 , 128 are fixed to the rod or tube elements 118 , 120 , for example can be welded. Alternatively, however, it is also possible to insert the screw spindles 130 , 132 with the nut elements 126 , 128 screwed thereon only into corresponding recesses in the rod and tube elements 118 , 120 and then to adjust the position or clamp the sleepers 20, the nut elements 126 , 128 turn in order to move the screw spindles 130 , 132 , which may then be held against rotation, in the longitudinal direction L of the sleeper.

By using this third support device 114 , the two-block sleepers 20 can also be supported in the longitudinal direction L of the sleepers with respect to the track grating support plate 12 even if the latter has no trough cheeks. However, it serve a respective first reinforcement arrangement for bi-block sleepers 20 forming Beweh guide elements 104 not only ensures by 20 with respect to the track grid support plate to get in the supporting land a defined mounting of the bi-block sleepers 12 in the sleeper longitudinal direction L, but carry these reinforcement members 104, as shown in Described below, at the same time to maintain a defined and dense reinforcement structure, in particular in the area of the individual two-block sleepers 20 . In order to clarify this, the procedure for producing a fixed railroad track is described below, as is shown in FIGS. 6-10.

After the hydraulically bound base layer 102 has been manufactured in a manner known per se, or a different type of subsoil has been provided, the substantially flat-formed support plate 12 is manufactured, for example, by a slipform paver, with the reinforcement 100 already mentioned being incorporated into it at the same time is introduced. Even before this track support plate 12 has completely hardened, as already described above, the reinforcement elements 104 forming the first reinforcement arrangements are then provided in the respectively desired positions, ie ultimately in each case in an area that comes to lie between two sleeper blocks 22 of a two-block sleeper 20 . In a corresponding manner, reinforcement elements 140 are introduced into the track support plate 12 at the areas adjacent to the outer ends 42 of the sleeper blocks 22 . These reinforcement elements 140 can also be bent from structural steel rods, for example U-shaped reinforcement elements with U-legs 142 , 144 and web sections 146 connecting them. These reinforcement elements 140 can be pressed into the not yet hardened material of the track support plate 12 or inserted until they stand up again with their U-legs 142 , 144 on the ground or the hydraulically bound support plate 102 . The reinforcement elements 140 form a second reinforcement arrangement for interaction with the respective two-block sleepers 20 and are introduced in such a way that their U-legs 142 , 144 are spaced apart in the longitudinal direction R of the road. The distance between the U-legs 142 , 144 in the longitudinal direction R is such that at least one of the reinforcing elements 32 or 34 projecting beyond the outer ends 42 lies in the area between these two U-legs 142 , 144 , preferably all of them protruding reinforcement elements 32 , 34 between the U-legs 142 , 144 of a reinforcement element 140 . In Figs. 6 and 7, the reinforcement element shown on the right side in each case is shown in its preparation ply 140th The respective reinforcement element 140 with its area protruding beyond the top 112 of the track support plate 12 is bent outwards, ie away from the adjacent sleeper block 22 , so that it is ultimately close to the top 112 . The introduction in this preparation position has the advantage that, on the one hand, the track support plate 12 can be driven over by trucks for separating the sleepers, the tires of which generally roll in those areas in which the reinforcement elements 140 are also to be introduced. Furthermore, this results in the advantage that the individual two-block sleepers 20 with their laterally projecting reinforcement elements 32 , 44 can be placed from above without being hindered by the web sections 146 of the reinforcement elements 140 .

After the sleepers 22 are adjusted in the manner described above and are held in a defined manner by the various support devices 56 , 58 , 114 by support on the top 112 of the track support plate 12 or the reinforcement elements 104 , the spaces 150 between the Bottoms 152 of the threshold blocks 22 and the top 112 of the track support plate 12 are filled with fixing material, for example fast-setting fixing concrete material 154 , or at least partially filled, as can be seen in FIG. 9. After this fixing material 154 has hardened or at least partially hardened, this material alone, which creates a material connection both to the track grate support plate 12 and to the respective sleeper blocks 22 due to the surface roughness, is held and fixed in its position, so that the various support devices are now 56 , 58 , 114 can be removed. It is now advantageous if, as has already been described above, the plate-like support elements of the first and second support devices 56 , 58 are not welded to the reinforcement elements 32 , 34 of the reinforcement cages 26 , 28 , but are only applied to them from below. The support devices 56 , 58 can then be completely removed and can be used again completely. In addition to the advantage that these various support devices 56 , 58 , 114 can be reused in this way, there is also the advantage that these corrosion-critical elements do not remain in the filling concrete layer to be subsequently formed.

Either before or after the introduction of the fixing material 154 , the reinforcement elements 140 can then be bent into their installation position, as can be seen in FIG. 9 and, for example, can also be seen in FIG. 6, left side. In this installation position, the web section 146 then lies over the sections of the reinforcement elements 32 , 34 which laterally project beyond the threshold blocks 22 . The reinforcement elements 140 brought into their installation position, which, as already stated, ultimately represent a second reinforcement arrangement for interacting with a respective two-block threshold 20 , and the reinforcement elements 104 create a tightly meshing reinforcement network in the area of each individual two-block threshold 120 , which in the Filled concrete layer to be produced ensures a high degree of stability, particularly in the very heavily loaded areas, namely the areas in which the sleepers 20 lie. In order to improve this stability even further, longitudinal reinforcement elements 160 can be introduced, which extend in the longitudinal direction R of the reinforcement cages 26 , 28 and extend under the connecting webs 110 of the reinforcement elements 104 . In this way, an interwoven reinforcement network is ultimately provided.

Now that all the supporting devices have been removed and the desired reinforcement network has been created, the material for the filler concrete layer 162 shown in FIG. 10 is then applied, for example by means of a slipform paver. This material then partially surrounds the threshold blocks 22 of the two-block sleepers 20 and completely surrounds the reinforcement network formed over the top 112 of the track support plate 12 , comprising the connection arrangement 24 , ie the sections of the associated reinforcement elements projecting beyond the threshold blocks 22 , the reinforcement elements 104 and 140 in their the track support plate 12 protruding sections and the longitudinal reinforcement elements 160 and possibly even further outside the two-block sleepers 20 positioned longitudinal reinforcement elements 164 or transverse reinforcement elements 166 positioned between individual two-block sleepers. It can thus be seen that the reinforcement elements 104 of the first reinforcement arrangement and the reinforcement elements 140 of the second reinforcement arrangement gl 13058 00070 552 001000280000000200012000285911294700040 0002010021962 00004 12939 also provide a firm connection between the filler concrete layer 162 and the track support plate 12 .

It should be noted that the reinforcement elements 104 , 140 of the first and the second reinforcement arrangement could of course be designed in a different way. For example, the reinforcement elements 104 could also only include the leg regions 106 , 108 with possible short sections which are provided thereon and extend approximately horizontally. Self-contained rectangular reinforcement frames could also be used. The use of such reinforcement elements has the particular advantage that it is possible to manufacture the track grating support plate 12 without any protruding step sections, so that ultimately the drainage of water is also guaranteed in the lateral direction, especially in the case of excessive rail carriageways. Of course, it is also possible, in the embodiment, as has been described with reference to FIGS. 6-10, on the track support plate 12 also to provide the side walls which can be seen in FIGS. 1-5, ie essentially with a trough-like configuration to train. Here, too, the advantages resulting from the introduction of the reinforcement elements 104 or / and 140 can be used both in the adjustment and in the construction of a dense reinforcement network in the area of the individual two-block sleepers. The support in the threshold longitudinal direction L can then be carried out both on the trough side walls and on the reinforcement elements 104 .

Another embodiment of a support arrangement according to the invention is shown in FIGS . 11-14. It can be seen that in this type of configuration, the support arrangement 54 assigned to each of the threshold blocks comprises a support frame, generally designated 200. In the embodiment shown, the support frame 200 comprises four frame parts 202 , 204 , 206 , 208 . Of these, the frame parts 202 , 204 extend in the longitudinal longitudinal direction L along a respective associated threshold block 22 , and the frame parts 206 , 208 extend along the end regions 42 , 44 transversely to the longitudinal longitudinal direction L.

In the respective end regions of the frame parts 202 , 204 lying in the longitudinal direction L of the threshold, filling / venting nozzles 210 , 212 , 214 , 216, for example formed in a square tube-like manner, are firmly connected to them, for example by welding. At these end areas, both the connecting pieces 210 , 212 , 214 , 216 and the frame parts 202 , 204 each have opening areas 218 , 220 which lead into the space area surrounded by the support frame 200 . Furthermore, respective hook-like coupling plates 222 , 224 , 226 , 228 are attached to the connecting pieces 210 , 112 , 214 , 216 , which can be pushed onto lateral end regions of the frame parts 206 , 208 from above, so that ultimately the frame parts 202 , 204 hang on the frame parts 206 , 208 with the sockets 210 , 212 , 214 , 216 carried thereon. Furthermore, the frame parts 206 , 208 carry on their inwardly facing side support elements 230 , 232 , on which, as can be seen in FIG. 11, a respective threshold block 22 with the lower surface comes to rest in its end regions 40 , 42 .

On the two frame parts 206 , 208 , plate parts 234 , 236 projecting approximately horizontally or laterally from them are fixed, for example by welding. The respective screw spindles 64 , 64 'and 74 , 76 of the first support device 56 and the second support device 58 interact with these two plate parts 234 , 236 . For example, it can be provided that respective nut elements 238 , 240 are attached, for example welded, to the plate parts 234 , 236 on their underside. The screw spindles 64 , 64 ', 74 , 76 are then screwed through corresponding openings in the plate parts 234 , 236 and into the nut elements 238 , 240 , so that they are supported with their free end regions towards the platform support plate 12 . By turning the screw spindles 64 , 64 ', 74 , 76 , the height of the support frame 200 , and in a corresponding manner also the transverse or longitudinal inclination of the same, with respect to the track support plate 12, can be set, so that the position of a correspondingly on the support frame 200 supporting or supported threshold block 22 can be adjusted.

In order to also obtain support in the longitudinal direction L of the sleeper, for example, at least one additional screw spindle 84 is again provided in the region of the second support device 58 . This can be supported, for example, by means of an assigned nut element 82 on an essentially tubular support element 250 , which in turn is fixed to the plate part 236, for example by welding. It should be pointed out that, of course, in the other end area, that is to say in the case of the frame part 206 , lateral support can also take place with respect to a support bracket provided in the track support plate 12 , as was described above.

In order to maintain a lateral hold of the frame parts 202 , 204 carrying the coupling plates 222 , 224 , 226 , 228 on the frame parts 206 , 208 , the frame parts 206 , 208 in their end regions can each be raised with abutment sections 260 , 262 , 264 , 266 be formed on which the coupling plates 220 , 224 , 226 , 228 can be supported on the outside. Inward support is provided on the respective plate parts 234 , 236 .

When using the support arrangement 54 shown in FIGS . 11-14, the procedure is such that, for example for a respective two-block sleeper 20, the support frame 200 assigned to the two sleeper blocks 22 , as can be seen, for example, in FIGS . 12-14, approximately there be parked where a two-block threshold 20 is to be positioned. For this purpose, the individual frame parts 202 , 204 , 206 , 208 can be put together as described above, ie plugged together or, if necessary, also screwed together. Subsequently, a two-block sleeper 20 with its two sleeper blocks 22 is placed on the respectively assigned support arrangements 54 , ie the support frame 200 , until it rests on the elements 230 , 232 . Then, by turning the screw spindles 64 , 64 ', 74 , 76 , 84 and possibly further screw spindles supporting in another direction, a respective support frame 200 having or supporting the support devices 56 , 58 with the threshold block 22 lying thereon is brought into the desired installation position brought. In this intended installation position, the support frame 200 with its plate-like frame parts 202 , 204 , 206 , 208 then surrounds the intermediate space 150 formed between the respective sleeper block 22 and the track grid support plate 12 in the manner of a formwork. In order to achieve an almost tight seal to the track support plate 12 , sealing elements, for example sealing lips 252 , can additionally be provided on the frame parts 202 , 204 , 206 , 208 , which come to rest on the surface of the track support plate 12 and can also be deformed in the process . Then, for example, the relining material, for example the fixing concrete, is filled in by the nozzles 212 , 216 lying on the right in FIG. 12, in such a way that, when viewing FIG. 11, it fills the space 150 from left to right and thereby the displaced air can escape through the nozzle 210 , 214 . During this filling process, the nozzles 210 , 214 , which are open at the top, can then be observed, so that when the relining material in these nozzles rises, a certain filling level is recognized at which the intermediate space 150 is completely filled. In elevated areas, the procedure can preferably be such that the filling is carried out from the lower side and then, under pressure, it is ensured that the relining material is conveyed to the higher side. After the at least partial hardening of the relining material, the screw spindles 64 , 64 ', 74 , 76 and 84 can then be loosened or loosened, the individual frame parts 202 , 204 , 206 , 208 can be loosened from one another again and thus removed from the associated sleeper blocks 22 and be used for another threshold block.

The support arrangement 54 shown in FIGS . 11-14 simultaneously forms a formwork around a respective sleeper block, which simplifies the introduction of the relining material for fixing the sleeper blocks. The entire support arrangement is reusable due to its ability to be taken apart, thereby preventing the introduction of foreign materials into the filling concrete layer to be subsequently formed. It should be pointed out that various modifications of this support arrangement are of course possible here; For example, instead of the four-part design of the support frame described, a two-part design with L-shaped parts, for example formed from firmly connected frame parts 202 and 206 or 204 and 208, is possible, these L-shaped sections then being connected to one another in two areas, for example Coupling can be coupled. It is also possible in principle, not to couple the screw spindles or the individual supporting devices 56, 58 in the illustrated manner fixed to the support frame, but to create here a releasable connection, in which the individual Abstützeinrich obligations 56, 58 then to the appropriate Time can be provided on the support frame 200 . It is also a matter of course that the individual screw spindles can also be screwed into respective openings of the support frame provided with internal threads at the location of the nut elements shown.

Of course, the number of filling openings or Filling / venting spigot can be changed or their position can also be changed or inclination can be changed in such a way that on the one hand a safe filling of the relining material is possible, but on the other hand also a disturbance with and immediately adjacent thresholds seen support arrangements is avoided.
