Abstract

The sleeper block has a block body (2) and a base (3), which is formed from elastic esp. closed-pore material (5). The sides (4) extending from the base are at least partially formed from similar closed-pore material, constructed in a ring, which is connected to the base by esp. contact pressure. The materials of sole and sides have different elastic characteristics and/or strength. The sleeper block and/or a block unit, are fitted into a concrete track bed, which also has a connection support. For height correction of the superstructure, the block is lifted out of the track bed and re-positioned. The free space between sleeper block and track bed is filled esp. with concrete, and a layer of compensation material, esp. concrete, is applied, when the desired height is reached.

Description

The present invention relates to a sleeper block for insertion into a track superstructure a solid road. Furthermore, the present invention relates to a Sleeper block unit for insertion into a track superstructure of a fixed. Roadway, as well as a method and a mold for producing a threshold block or a sleeper block unit for insertion into a track superstructure of a fixed Roadway. Furthermore, the present invention relates to a track superstructure solid roadway with a sleeper block unit and a method for height correction a track superstructure of a fixed carriageway.

So-called fixed carriageways are used on railway lines, particularly in the high-speed range and used in the tunnel area. With a firm road the ballast is replaced by another material, e.g. Concrete or asphalt, replaced. Thereby the stability of the road surface is increased and deformations caused by the loads of a Train will be reduced. Solid carriageways have a long service life and low Maintenance and repair expenses.

In order to ensure a certain minimum elasticity of the rail on solid carriageways, elastic rail fastenings have already been provided, which the rail on fasten the concrete bed or the sleeper blocks of the elastic carriageway. such elastic bearings are necessary to ensure driving comfort and noise emissions to improve.

Furthermore, a so-called swell shoe was proposed in DE 43 35 516 A1. This sleeper shoe consists of a bottom part with vertical side walls, which is made as an extrusion from an elastomeric material. Furthermore are End caps are provided to close the respective ends of the sleeper shoe. The two end caps are with the base, consisting of the bottom part and vertical Side walls glued or vulcanized to achieve a tight connection. This sleeper shoe is pulled over a concrete sleeper, with a Barbs on the shoe in a corresponding recess of the threshold is held. Sealing lips are also provided to prevent water from entering and dirt in the area between the concrete sleeper and the sleeper shoe prevent. Such a concrete sleeper is about 2.6 m long, with each of the concrete sleepers carries both rails.

Furthermore, DE 36 02 669 A1 describes a resilient covering for a concrete sleeper known. This creates an elastic coating layer on the bottom and side walls foamed on the concrete sleeper. In the manufacturing process, the concrete sleeper inserted in a mold and a given space between the concrete threshold and the mold with polyurethane elastomers, an adhesive Connection between the foam material and the concrete sleeper is created. This foam-covered concrete sleeper is then poured into the concrete bed of a solid carriageway. The foamed covering layer covers the floor of the concrete sleeper and part of the side walls.

A system is known in the manufacture of solid carriageways in which two Threshold blocks are connected with an L-shaped profile. These two threshold blocks each carry a track and are fixed in the concrete bed Potted roadway. Due to the elastic mounting, the L-shaped connection profile not be included in the concrete bed. Therefore, a given one Distance of, for example, 2 to 3 cm between the so-called filling concrete of the concrete basin and the L-shaped connection profile remain. This L-shaped connection profile serves as a tie rod to both the track gauge (the distance between the two Rails) as well as the inclination of the rail on the threshold.

A fixed roadway is also known, with two independent threshold blocks are provided, each carrying a track. Because with this system there is no connecting rod, there is a higher embedding depth in the filling concrete of the concrete bed possible. The greater embedment depth increases the strength of the road elevated. However, it is disadvantageous with this system that when adjusting the track In addition to the height and direction of the track, the track width and the inclination adjusted using special straightening systems and fixed during concreting have to.

For both systems mentioned above, a rubber shoe with an inserted elastic layer covered over the threshold blocks and then embedded in the filling concrete. Attaching these rubber shoes to the sleeper blocks is relatively labor intensive. The rubber shoes must be secured with straps for transport. Furthermore, the rubber shoe has a relatively high weight, so that when adjusting of the track in the sole of the rubber shoe a certain sag that arises water or the like is reinforced. Water can e.g. very easily along the Penetrate the surface of the sleeper block between it and the rubber shoe, when the sleepers are stored or transported outdoors with the rubber shoe on become. The penetration of cement slurry or the like. during concreting as well as water between the concrete sleeper blocks and the rubber shoe by sealing, such as masking or special care when concreting, be prevented.

The use of a slip-on rubber shoe allows easy replacement the threshold block, which is lifted out of the rubber shoe.

The present invention is described and explained in more detail below on the basis of exemplary embodiments in conjunction with the associated drawings. In these shows:

Fig. 3

a sleeper block unit in a track superstructure of a fixed carriageway.

Fig. 1 shows a first embodiment of the threshold block, inserted in a Track superstructure of a fixed carriageway, in a side sectional view. The one in Fig. 1 The threshold block 1 shown is inserted into a concrete bed 12 of the solid carriageway. This Threshold block 1 has a sole surface 3 and starts from this sole surface 3 Side surfaces 4 on. An upper surface arranged opposite the sole surface 3 is intended for the assembly of one or two rail tracks (not shown). The sole surface 3 of the sleeper block 1 is made entirely of an elastic material 5 formed. The side faces 4 of the threshold block 1 are, as shown in FIG. 1, partially formed from elastic material 5. The core of threshold block 1 is formed by a sleeper block body 2 made of concrete. Each of the side surfaces 4 will from an outer surface 5a of the elastic material 5 and an outer surface 7b of the Threshold block body formed.

The elastic material 5 shown is preferably closed-pore in order to Avoid absorption of moisture. So that the properties of the elastic Materials under various weather conditions, such as rain or frost.

The elastic material 5 of the sole surface 3 and the side surfaces 4 can be the same Have properties and / or material thicknesses.

Alternatively, different ones can be used for the elastic adjustment of the sleeper block Materials, i.e. Materials with different elastic properties and / or material thicknesses, provided for the sole surface and the respective side surfaces become.

The side surfaces 4 of the sleeper block according to FIG. 1 are inclined sections 4a educated. According to the exemplary embodiment shown, the side surfaces are therefore 4th in the direction of the sole surface 3 to a vertical central plane 6 of the sleeper block inclined towards. The exemplary embodiment shows an inclination of 1:20. Through the The threshold block is designed symmetrically with respect to the central plane 6 a conical or V-shaped shape of the sleeper block, this in the direction tapered into the concrete bed 12. The side surfaces in the area of the drawing plane of the Fig. 1 are also corresponding to the side surfaces 4 shown to a vertical Center plane inclined, which is perpendicular to the vertical center plane 6 shown.

In the first embodiment, the side surfaces 4 are essentially complete formed as inclined sections 4a. Alternatively, the side surfaces can also partially formed with inclined sections. Thus, one side surface an inclined and a vertical section or a section inclined in the opposite direction exhibit. For example, the transition from the vertical to the inclined section in the area of the transition of the outer surface of the elastic material and the Outer surface portion of the sleeper body.

The inclined portions of the side surfaces facilitate the manufacture of the sleeper block and the replacement of an already used threshold block like this will be explained later.

The threshold block shown in Fig. 1 is symmetrical with respect to the vertical planes educated. Furthermore, the threshold block according to the first embodiment be designed as an integral sleeper block for supporting both rail tracks.

Alternatively, the threshold block of the first embodiment can be used for storage a rail track can be provided. In this case, two blocks are in each case Dependency of the track gauge and the desired inclination in the track superstructure a fixed roadway.

As shown in Fig. 1, the sleeper block 1 is in the concrete bed 12 of the slab track concreted or poured, the entire sole surface and part of the side surfaces are recorded in the concrete bed. The area of the side surfaces that through the elastic material is formed, extends out of the concrete bed 12.

As shown in the cross section of FIG. 1, the threshold block 1 has the threshold block body 2 with a step section 7 in the area of the outer surface 4. This Step portion 7 is through the outer surface portion 7b of the threshold block body on the side surface 4 of the threshold block 1 and a recessed outer surface section 7a of the threshold block body 2 is formed. The elastic material 5 is in Area of the recessed outer surface portion 7a of the threshold block body 2 arranged. The recessed portion 7a of the threshold block body 2 is as shown in FIG the thickness of the elastic material 5 is formed such that the outer surface 4 the threshold block 1 forms a step-free transition. Through this stepless Transition can reduce damage during transport, for example, and that Accumulation of dirt or the like be avoided. This turns the threshold block into an integral, monolithic shape.

In the exemplary embodiment shown, the side surface, as already explained, has a constant slope on. The outer surface 5a of the elastic material 5 is thus aligned and the outer surface portion 7b of the threshold block body 2 so that none Edge on the side surface 4 forms.

In Fig. 2 is a second embodiment of the threshold block 1 in a side sectional view shown. The threshold block of the second embodiment is similar the threshold block of the first embodiment, so that subsequently the differences from the first embodiment are explained. The remaining Features of the threshold block of the second embodiment correspond to Features of the threshold block of the first embodiment, and it is based on a Repetition of explanations waived.

As shown in Fig. 2, the threshold block 1 of the second embodiment Side surfaces on each with two inclined sections 4b and 4c. This inclined Sections 4b, 4c are similar to the inclined sections of the first embodiment towards the sole surface 3 to the vertical central plane of the sleeper block 1 inclined. The first inclined section 4b is adjacent to the sole surface 3 more inclined than the second inclined portion 4c adjacent to the first inclined section 4b. According to the exemplary embodiment shown, the first has an inclined Section an inclination of 1: 5, and the second inclined section an inclination from 1:20. The sleeper block thus tapers in the direction of the sole surface 3, i.e. the more he protrudes into the concrete bed 12, the stronger.

The threshold block 1 according to the second embodiment has a step portion 7, which, as described in connection with the first embodiment, is trained.

The inclined portions 4b and 4c of the side surface 4 of the second embodiment are formed by the elastic material. In the area of the transition of The first inclined portion 4b to the second inclined portion 4c becomes theoretical an edge is formed in the side surface 4. Because this edge is in the range of elastic Material 5 of the side surface 4, no sharp or hard edge is formed, so the risk of damage in the transition area, in particular when transporting or handling the sleeper block is avoided.

An adhesive bond between the elastic material 5 and the threshold block body 2 is different from an adhesive bond between the elastic material 5 and the concrete bed 12. Preferably, the adhesive bond between the elastic Material 5 and the threshold block body 2 larger than the adhesive bond between the elastic material 5 and the concrete bed 12.

The threshold block 1 according to the first and second exemplary embodiments can be simplified Used in the concrete bed of a solid carriageway with a higher embedding depth become. Furthermore, the threshold block 1 according to the first and second exemplary embodiment allows a simple height correction, as will be explained below.

In threshold block 1 according to the first and second exemplary embodiments, it is preferred different materials on the side (side surfaces) and below (brine surface) or to use different properties and strengths. This will make the elastic storage of the sleeper block in the concrete bed set in the desired manner. The elastic mounting of the sleeper block in the concrete bed is according to the specified elastic deflection in the vertical and horizontal directions. According to the exemplary embodiments, the elastic material 5 is on the side surfaces 4 formed as a closed ring and with the elastic material on the Sole surface, in particular connected by contact pressure. The side elastic Layer and the elastic sole surface are formed at the corner such that when No sustainable sound bridge can be built in concrete. Cement slurry with with a thickness of 0.5 - 1 mm thickness are broken and is therefore not a structure-borne noise bridge. The lateral elastic layer is preferred pulled down in order to pull the sleeper block (exchange or height correction, which is described below) the sole coating before Protect peeling on the edge.

The threshold block 1 according to the first and second exemplary embodiment with the sole surface, which is made of elastic material, and with side surfaces, at least are partially formed from elastic material, has a high dimensional accuracy. The outer dimensions of the sleeper block have tight tolerances. This will handling is simplified and standardization is possible. These tight tolerances facilitate the replacement of the sleeper block, as will be described below is. This high dimensional accuracy is made possible by the elastic Material 5, e.g. in the form of mats, is connected to the threshold block body 2 to form the monolithic sill block.

In Fig. 3 is a threshold block unit for insertion into a track superstructure solid roadway shown. This threshold block unit 8 has a first and a first second threshold block 1, which are connected to one another by a connecting support 9 are. These threshold blocks 1 are according to the first and second exemplary embodiments 1 and 2, so that the explanations are repeated is waived. Alternatively, the threshold block unit can also be used with others, for example conventional threshold blocks are formed.

As shown in Fig. 3, the threshold block unit 8 has opposite each other Threshold blocks 1, which are connected by the connection carrier 9. Everyone who The threshold blocks 1 shown are provided for mounting a rail (not shown). The distance between the two threshold blocks 1 is dependent on the connection carrier 9 the gauge. Furthermore, the inclination through the connection carrier 9 of blocks 1 for setting the rail inclination. Preferably the two sleeper blocks 1 are connected to one another by two connecting supports.

The connection support 9 is designed as a so-called lattice support and at least has two, i.e. an upper and a lower cross strut 9a (b), 9c. Preferably are three, i.e. two upper and one lower cross strut 9a, 9b, 9c are provided. alternative it is also possible to use one upper and two lower cross struts or rods. These cross struts 9a, 9b, 9c each extend into the sleeper blocks 1, such as this is shown by the broken line in Fig. 3. These cross struts are used in the Manufacturing method of the threshold blocks 1 introduced into the respective molds in order to manufacture the threshold block unit 8.

As shown in Fig. 3, the cross struts 9a, 9b, 9c are truss-like in a central section braced with each other in order to achieve the necessary rigidity of the sleeper block unit receive. This stiffness is necessary to ensure that it can be handled (storage, transport, Installation) and the adjustment of the sleeper block unit when inserted into the track superstructure to simplify the slab track. Machines and devices, which are generally known from ballast track construction in the construction of the fixed Lane are used.

As shown on the left side of FIG. 3, the cross struts 9a, 9b, 9c are in one section not braced adjacent to the sleeper block 1. In this Area, adjacent to the sleeper block 1, are the mentioned cross struts provided with an elastic covering 10. This elastic covering 10 is made made of an elastic material, e.g. Foam or polystyrene. This elastic Envelope 10 allows decoupling of threshold block 1 when the threshold block unit 8 is inserted into the concrete bed 12, the connecting support 9 in the Concrete bed 12 is added.

When loaded, it is necessary that the elastically mounted sleeper block 1 sink can. Would the connection carrier 9 completely and strongly coupled in the Such a lowering of the sleeper block 1 would be included in the concrete bed 12 not possible. Due to the elastic covering 10 of the cross struts 9a, 9b, 9c of the connection carrier adjacent to the threshold block 1 is a bend of the individual Cross struts or bars possible in this area. This bend creates elasticity ensures that the threshold block 1 can be lowered. Through the elastic covering 10, the bend is not hindered by the concrete bed 12. This Bending of the individual cross struts can be done by an appropriate choice of cross sections of the individual cross struts are favored or specifically determined. For example one or more predetermined bending points, e.g. Cross-sectional weaknesses, formed on the individual cross struts in the region of the elastic covering 10 his.

The elasticity mentioned by the bending of the cross member 9a, 9b, 9c adjacent to the Threshold block 1 is directed essentially perpendicular to the connection carrier 9. Lateral forces, in particular tensile forces, in the longitudinal direction of the connection carrier 9, i.e. are directed in the longitudinal direction of the cross struts 9a, 9b, 9c, by the cross member transferred and supported so that this connection acts as a kind of tie rod the lateral displacement of the sleeper block unit 8 acts in the fixed lane.

To ensure the elastic mounting of the sleeper block 1 can alternatively the aforementioned elastic sheath 10, the cross member adjacent to the Cut threshold block 1 after inserting and curing concrete bed 12 become. In order to simplify such a severing, there is a spacing element 11 adjacent to the threshold block 1, as shown on the right Side of Fig. 3 is shown. This spacer 11 forms in the area of the cross member 9 a type of joint that extends to the surface of the concrete bed 12. It is the spacer 11 made of an easily removable material or a material that creates a low resistance for a cutting tool. Such a material is for example foam or polystyrene.

The severing can also be done by special measures (cross-sectional weakening or installation of brittle intermediate parts) of the upper and lower cross struts Target breaking points are simplified. Ideally, these prepared spots break reliable when the track is first loaded by a heavy train. such Desired breaking points can also be used in connection with the elastic described above Wrapping 10 are used. The elastic covering 10 enables the necessary displacement on the individual cross struts to trigger the break. Are these predetermined breaking points designed so that the breakage is caused by the first load If the track is pulled by a heavy train, the concrete bed will not open necessary to achieve the decoupling of the sleeper block from the concrete bed.

As shown on the right side of FIG. 3, when using the spacer extends 11 the truss-like strut of the connecting support 9 up to the Area of the spacer 11. This makes the stiffness of the sleeper block unit 8 increased for handling, inserting and adjusting the same. After cutting of the connection carrier 9, the threshold block is essentially complete decoupled to allow lowering under load. So with this variant the connecting support 9 is essentially a pure assembly aid.

In Fig. 3, the threshold block unit is on the left side with an elastic covering 10 and provided on the right side with a spacer 11. This Mixed construction is advantageous if for a sleeper block (right sleeper block) an essentially complete decoupling is desired while for the other Threshold block (left threshold block) in addition to the sufficient elasticity also the recording lateral tensile forces through the truss-like braced connecting bracket 9 is desired. For example, this can occur in tight radii with large cantilevers Case.

As an alternative to the mixed construction shown, the threshold block unit can be used on both Sides have the elastic covering 10 or the spacer 11. In the The above-mentioned embodiment with two connecting beams can both the mentioned Mixed construction can be carried out as well as a variant in which both sides of the two Connection carrier with the elastic covering 10 or the spacer element 11 are trained.

In addition to the aforementioned variants of the threshold block unit, the elastic covering can be combined with a spacer. It enables the elastic covering a corresponding elasticity of the threshold block, while the spacer simplifies refurbishment of the sleeper block assembly, like this will be explained below.

As an alternative to the variants shown or described, the lower or the upper cross struts are formed with the elastic covering, and each remaining cross struts can be provided for severing. The can upper cross struts through an opening and using a cutting tool or the like. There is also one for the upper and lower cross struts Cut through a predetermined breaking point the first time a heavy train is loaded possible. By connecting the sleeper block to the connecting beam with only one cross strut (or the cross struts in a plane perpendicular to the sinking movement) the resistance against the sinking movement through the connection carrier are reduced after the sleeper block unit is inserted into the concrete bed is. This increases the degree of decoupling and still supports Shear forces in the direction of the remaining cross strut (s) possible.

The exemplary embodiments as shown in FIGS. 1 to 3 and the preceding ones Variants described, show schematically a track superstructure of a fixed Roadway. In this track superstructure there is a sleeper block according to the first or second embodiment included in the concrete bed 12. Furthermore is a Track superstructure of a fixed carriageway with a sleeper block unit 8 in connection described with Fig. 3.

In the described threshold blocks 1 there is an adhesive connection between the elastic Material 5 and the threshold block body 2 different to an adhesive connection between the elastic material 5 and the concrete bed 12. This is done Removal of threshold block 1 in a defined manner during renovation, i.e. either the threshold block body 2 is released from the threshold block 1 and that elastic material 5 remains in the concrete bed 12, or the threshold block 1 is in the Entirely removed from the concrete bed 12. In the first variant, the adhesive bond between the elastic material 5 and the threshold block body 2 less is as the adhesive bond between the elastic material 5 and the concrete bed 12 the threshold block body 2 can be replaced without the elastic material 5 needs to be replaced.

However, it is preferred that the adhesive bond between the elastic material 5 and the concrete bed 12 is less than the adhesive bond between the threshold block body 2 and the elastic material 5, so that the threshold block 1 always as Whole removed from the concrete bed 12 and through a similar threshold block 1 can be replaced.

The following is the procedure for making a threshold block for insertion described in a track superstructure of a fixed carriageway. This procedure can both for the manufacture of the sleeper block according to the first embodiment as well as for the manufacture of the sleeper block according to the second embodiment be used. Furthermore, the method for producing the Threshold block unit can be used.

In the method of manufacturing the sleeper block, a mold (not shown) is used, the inner surfaces of which form the side surfaces 4 of the sleeper block 1 are trained. Such a shape is usually formed in two parts. Doing so the elastic material is inserted into the mold and concrete is filled into the mold To form threshold block body 2. The threshold block is removed, this has a sole surface made of elastic material and has side surfaces which are at least partially formed from elastic material.

According to the method, the threshold block is manufactured overhead, i.e. the Form is open in the area to form the sole surface. With this procedure the elastic material 5 for all side surfaces 4 of the sleeper block 1 as a ring in the Form used. Then concrete is poured into the mold and compacted. following the elastic material for forming the sole surface is placed from above, in shook the fresh concrete and overturned the form for demoulding.

The "overhead" production, i.e. the threshold is followed by the rail attachment manufactured below, allows high accuracy in terms of contact areas for the Rail fastening, especially the positioning of the embedded dowels. Farther is the surface contour on the side of the rail fastening and the concrete quality the contact surface rail fastening - threshold in the desired manner. With the "overhead" production, the high requirements can be met.

A multi-part mold is used to manufacture the sleeper block. This Form has a basic formwork in which the exact form in the area of the rail supports and rail fastening including the position of dowels. This Basic formwork has receiving devices for the dowels in the area of the base Rail fastening.

The side walls of the mold for forming the side surfaces of the sleeper block are as foldable or pivotable side walls. For the production of a sleeper block this shape has four foldable side walls, with an inclination of approx. 1:10 can be moved outwards to approx. 1:20 inwards. These flaps (foldable Side walls) can be flat (flat inner surface), for example around a sleeper block to manufacture according to the first embodiment; or can kink (Inner surface with two differently inclined surface sections) with or without fillet included, for example, a threshold block according to the second embodiment manufacture. For the movement of the foldable side walls is a Drive provided. This drive can be hydraulic, pneumatic or mechanical respectively.

In the open state or the open position of the pivotable side walls the edges of these side walls are separated from each other so that the shape is easily accessible and the elastic material can be easily inserted. In the closed State or the closed position of the pivotable side walls are the Edges of these side walls form-fit in contact with one another and form together with the basic formwork, a mold space closed on five sides and open at the top is. The exact form of the formwork and the lateral corner formation is determined by the Form fit of the foldable side walls ensured at their edges. Depending on the training the edges become the foldable side walls in a predetermined order closed.

When the formwork or form is closed, the flaps are locked intended. This locking of the flaps prevents the further process steps from which are explained below, forces on the drive of the foldable Sidewalls work.

The foldable side walls of the formwork each have a holding device for Position the elastic material on. The elastic material is in shape of elastomer mats by negative pressure (vacuum) and / or by clasping the upper 5 to 10 cm of the elastomer mats.

Through this procedure, the sleeper block with the sole surface made of elastic Material is formed, and with side surfaces that are at least partially made of elastic Material are formed, high dimensional accuracy. The outside dimensions of the threshold block have tight tolerances. This simplifies handling and standardization is possible. These tight tolerances make it easier Replacing the threshold block as described below. This high dimensional accuracy is possible because the elastic material 5, e.g. in shape of mats into which the mold is inserted and connected to the sleeper block body is going to form the monolithic sill block. The outer dimensions of the Threshold block (with the elastic material) are due to the shape in tight tolerance certainly.

In the mold for the manufacture of the threshold block unit described above two opposing shapes are used, each of these shapes essentially is the same as the shape described above. In addition are for manufacturing the threshold block unit, the side walls facing the other shape are formed with openings, for example slots, around the connection carrier insert into the mold from above. The sealing can be preferred due to lost deposits made of plastic or wood in combination with the elastic material and any separating material for severing the cross struts can be achieved. Furthermore, a corresponding sealing element can be integral with the elastic described Envelope or formed according to the spacer described above his.

The work steps for producing a sleeper block or described a threshold block unit.

If necessary, the basic formwork is cleaned. This is done, for example, by blowing out the formwork. To make it easier to remove formwork, the formwork is sprayed with formwork oil. The dowels for the rail fastening are on the dowel holder of the formwork attached. If necessary, a threshold test is inserted into the form. at the manufacture of the sleeper block unit with opposing sleeper blocks the connection carrier is inserted into the respective shape from above, the corresponding Openings are sealed as described above.

The elastic material for the side surfaces, for example made of elastomer mats Form of a ring or two to four individual pieces is inserted into the mold and positioned. There is a stop device in the formwork for this positioning intended. These elastomer mats are made by vacuum (vacuum) or by Clasp held. The four side surfaces are inclined by one Folded inward on the outside to close the mold. In doing so the side flaps are positively connected at their edges. The order of the Folding is determined by the formation of the edges. The foldable side panels the form are locked after closing.

Concrete is poured and compacted into the closed and locked form. this happens in one or more work steps with dosing and pressing the concrete by a vibrating plate in stamp form from above. Then the vibrating plate lifted off and the elastic material for the sole surface applied. This elastic Material in the form of an elastomer mat is stamped from above using the vibrating plate pressed here and shaken.

To demould the threshold block or the threshold block unit, the entire Form together with a support plate on the hall floor or a conveyor overturned for further manipulation. The locking of the side foldable side panels are released and the foldable side panels are opened. Then will the formwork is lifted and stands for the production of another sleeper block or another threshold block unit.

By forming the shape with foldable side walls is in the manufacture of the Threshold block or the threshold block unit a fast clock sequence with a few Hand movements possible. By inserting a ring of elastic material for formation of the four side surfaces, these are closed in the area of the edges educated.

By simply replacing the foldable side walls, sleeper blocks can be placed in can be easily manufactured with different heights.

a) Sofortentschalung
Die frisch betonierte Schwellen wird unmittelbar nach dem Betonieren gestützt und entschalt. Der Fertigungstakt mit einer Schwellenform kann auf bis zu 60 sec. reduziert werden. Diese Verfahren ist für die beschriebene Art der Schwelle die bevorzugte Methode.

b) Spätentschalung
Der Beton erhärtet in der Schalung. Die Schwelle wird in der Regel nach 8-12 h aus der Schalung gehoben. Der Fertigungstakt mit einer Schwellenform beträgt ca. 12 - 24 Stunden.

There are basically two methods for formwork removal:

a) Immediate demoulding
The freshly concreted sleepers are supported and released immediately after concreting. The production cycle with a threshold shape can be reduced to up to 60 seconds. This method is the preferred method for the type of threshold described.

b) Late demoulding
The concrete hardens in the formwork. The threshold is usually lifted out of the formwork after 8-12 h. The production cycle with a threshold shape is approximately 12-24 hours.

In the method mentioned, the elastic material is inserted into the mold and adjusted. This is done for example by means of a stop or by vacuum or Brackets. Then concrete is poured into the mold.

Due to the inclined sections, i.e. the conical, tapered shape of the Demoulding is facilitated in the manufacture of the sleeper block.

By inserting the elastic material into the mold and the subsequent one Filling the concrete to form the threshold block body is easy Step section 7 explained above is formed, so that on the side surfaces 4 of the Threshold block 1 a smooth transition from the outer surface 5a of the elastic Material 5 to the outer surface portion 7b of the threshold block body 2 is formed.

In the threshold blocks 1 shown, the brine surface 3 is complete and the side surfaces 4 at least partially formed from elastic material 5. Through the step section 7 to the threshold block body 2 and the attached elastic material 5 an integral threshold block 1 created, the penetration of water and Dirt is prevented safely. Since the side surfaces 4 are stepless and the elastic material 5 is firmly connected to the threshold block body 2, a Accumulation of water and dirt is reduced without additional measures.

Furthermore, a track superstructure of a fixed carriageway is shown, in which, as in Fig. 3, the connecting support 9 is completely accommodated in the concrete bed 12. This is made possible by the elastic covering 10 or the spacing element 11, since this (as described above) provides the necessary elasticity of the threshold blocks 1 can be ensured. Through the complete inclusion of the connection carrier 9 the embedding depth of the threshold blocks 1 can be increased significantly. This will make the Strength of the solid road surface improved, so that stiffening measures, such as Reinforcements can be reduced or omitted.

Due to the high embedding depth, a height correction is possible in a simple manner like this will be explained below. In the exemplary embodiments shown, the connection carrier 9 completely included in the concrete bed 12. The maximum embedding depth is essentially determined by the rail and the rail fastening, a space must be provided for assembly and maintenance. Consequently can embed up to 140mm with a threshold block height of approx. 200mm and it is sufficient that the upper edge of the sleeper block is approx. 80mm is arranged above the surface of the concrete bed.

Furthermore results from the complete inclusion of the connection carrier 9 and the large embedding depth makes the road much smoother because of the exposed cross sleepers or cross members are not required. This reduces and decreases the air resistance of the road a trip hazard. The reduced air resistance already reduces the noise reduced when driving. Furthermore, by the more uniform Surface simplifies the application of sound absorbing coatings or coverings.

In the case of a track superstructure, a solid carriageway is in the area of switches and connecting tracks to turnout monoblock sleepers (in the track with 2 fastening points and used in the switch with up to 4 fastening points). There in the switch The length of the sleepers is constantly changing and the elastic material is in shape of mats to form the side surfaces and on the sole afterwards in the sleeper or glued to the sleeper block body at the construction site. Incidentally, are the threshold blocks for the area of a switch similar to those described above Threshold blocks formed.

By using the glued-on mats made of elastic material, the Threshold block with high dimensional accuracy designed as a monolithic sill block. The outer dimensions of the sleeper block have tight tolerances. These tight Tolerances make it easier to replace the sleeper block, as follows is still described.

In order to accommodate a deflection corresponding to the asymmetrical load can produce several different elastic in the area of the sole Materials, d. H. Materials with different elastic properties are used which are glued on to form the brine surface. To push these different Materials penetration of cement slurry, dirt and moisture To avoid this transition area is completely covered with adhesive tape.

The following is the renovation of a track superstructure according to the aforementioned Exemplary embodiments explained.

The removal of a threshold block 1 with inclined portions is as in the first and second embodiment shown, simply by lifting it out. there is preferably the adhesive bond between the elastic material 5 and the concrete bed 12 less than the adhesive bond between the elastic material 5 and the Threshold block body 2. Thus, the threshold block 1 can be removed as a whole in the event of defects and be replaced by a similar one. For reinstalling removed swelling blocks or exchanged swelling blocks becomes lubricant, preferably soap. This is advantageous because of the high thrust distances, which can accommodate the side materials to minimize when inserting.

In the threshold block unit 8, as shown in FIG. 3, the threshold block 1 can only be removed when the connection to the connection carrier 9 is cut is. This is already the case with the variant of the complete decoupling, as was described in detail above.

In the variant with the elastic covering 10 adjacent to the sleeper block 1 the cross struts 9a, 9b, 9c of the connecting support 9 must be severed in order to remove the threshold block 1. This can be done in such a way that the concrete bed 12 and the cross beams adjacent to the sleeper block 1 are severed. With regard to renovation, however, it is preferred that the elastic covering 10 in Connection with the spacer 11 on a side adjacent to the threshold block 1 is provided. The cutting of the cross struts 9a, 9b, 9c in easily done through the joint formed by the spacer 11. In this variant, however, the connection carrier 9 is only severed if if threshold block 1 is to be removed.

a) Einsatz von Trennscheiben und Durchschneiden an der Fuge zwischen dem Füllbeton und dem Schwellenblock,

b) die voraussichtliche Schnittfläche wird durch ein zusätzliches Material, bevorzugt aus Glasflies, freigehalten (Abstandselemente); innerhalb des Glasflieses kann der Schnitt geführt werden,

c) dieses Glasflies kann auch derart ausgebildet werden, dass durch Kraftscheren ein Abzwicken der Bewährungsstäbe ermöglicht wird,

   weiterhin können die Bewährungsstäbe bzw. der Verbindungsträger auch durch andere Verfahren, wie Abschlagen mit einem Meißel oder durch Herbeiführen von Korrosion, durchtrennt werden; dabei ist jedoch zu beachten, dass der derartig eingesetzte Mittel keine Negativauswirkungen auf den Beton als auch auf die elastischen Materialien, welche an der Schwelle ausgebildet sind, besitzen.In all of the above cases, the connection carrier can be severed by the following methods and methods:

a) use of cutting discs and cutting through on the joint between the filling concrete and the sleeper block,

b) the anticipated cut surface is kept free by an additional material, preferably made of glass fleece (spacer elements); the cut can be made within the glass tile,

c) this glass tile can also be designed in such a way that force shears enable the test bars to be pinched off,

furthermore, the test bars or the connection carrier can also be severed by other methods, such as chipping off with a chisel or by causing corrosion; however, it should be noted that the means used in this way have no negative effects on the concrete or on the elastic materials which are formed on the threshold.

These methods of severing can also be performed the first time the threshold block unit is inserted be used.

Another point of renovation is the so-called height correction. This will start with the necessary height correction was found. Minimal height corrections up to approx. 15 mm can be used in the rail fastening by using different thicknesses Intermediate layers and angle guide plates are made. Corresponding height corrections are carried out in 1mm steps. Height corrections from approx. 10 mm can by lifting the sleeper block 1 and pressing or Pour under the cavity under the threshold block 1.

Due to the embedding depth of the sleeper blocks of up to 140mm at a block height (Standard height) of approx. 200mm (lower edge of threshold block to upper edge of threshold block = Lower edge of the rail fastening) several correction passes) up to a height of 80 mm. When using around 50 mm higher sleeper blocks (250mm special height) the side elastic Layer increased from 150mm to approx. 200mm and thus an embedding depth of up to 190 mm with a correction reserve of approx. 120 mm.

By applying a reinforced compensation layer, for example made of concrete The original concrete bed can be the original embedding depth after the height correction be restored. For the application of this compensation layer, the existing one Concrete surfaces cleaned and the grain structure exposed if necessary by high pressure. As an additional measure, you can connect in the area of the threshold preheads the new, with the old concrete layer, pegs are drilled. This allows Height corrections by the appropriate amount again from scratch be performed. Thus, certain sections of the track are accumulated Height corrections possible. Through these repeated height corrections is an overall correction essentially unlimited scope possible.

The procedure for correcting the height of a track superstructure on a fixed carriageway, can with the previously described threshold blocks or the threshold blocks of threshold block units described above are performed. The threshold block is used with a specified embedding depth in a concrete bed (12) of the slab track. First, the sleeper block (1) is lifted out of the concrete bed (12) and into Positioned depending on a predetermined height correction. After that there will be a space between the threshold block (1) and a recess in the concrete bed (12) Filling material, especially concrete, filled up. This recess is created by removing it and position the threshold block as shown, for example, in FIG. 2 is shown. This procedure can be repeated several times, so repeated Height corrections at intervals or a correspondingly large height correction in several levels is possible.

With sleepers, an embedment depth of approx mm provided. There is a height reserve for height corrections of approx. 70 mm. Thus, the height corrections can be made up to an embedment depth of approx. 70 mm done without further application of a leveling layer. If a height reserve of more than 60mm after up to approx. 6 height corrections (under 10mm reserve) by applying a leveling layer that is at least 60-70mm thick the original embedding depth is restored, so that further height corrections can be done using the new correction pool. The layer out Compensation material, in particular concrete, is applied to the concrete bed 12 when a predetermined dimension of approx. 60 mm of a total height correction has been reached.

For structural reasons, the leveling layer is approx. 70mm, on the one hand to be able to accommodate reinforcement with the required concrete cover and on the other hand to ensure the necessary internal strength. Thin layers tend for crumbling and breaking. Avoid this. By applying the layer the predetermined embedding depth of the sleeper block essentially becomes from compensating material restored. The layer of compensating material is considered reinforced Layer with at least one reinforcement element, for example made of steel or plastic (e.g. GRP mats). A connecting element in is made up of the layer Compensation material and the concrete bed introduced to connect them.

This procedure can be done multiple times, making repeated height corrections at intervals or a correspondingly large height correction in several Levels is possible. So there is an essentially unlimited height correction possible.

A particular advantage of this procedure is that all described here Corrective measures can be carried out during breaks in just a few hours can. The train can then run at full speed without any restrictions be resumed immediately.

Through the inclined sections 4a-c shown in the exemplary embodiments the pressing or pouring in also in the area of the free flanks. To becomes the threshold block 1 attached to the rail in terms of height above the rail brought into the correct position. Then at least two corners of the Threshold between the filling concrete and the elastic material of the cannula from above inserted into the cavity below the threshold block 1. About a cannula the filling material is pressed in and the cavity is made corresponding via a second cannula vented. Such a cavity under the threshold block is in Fig2. shown.

The material is pressed in until it is in the diagonally opposite cannula swells upwards. With larger elevations, there is also a gap formation around around the coat. In this case, this gap is also shed. It can be found here the crack repair usual procedures with temporary sealing of the surface and subsequent Squeeze find use.

In order to remedy minor elevations in connection with the gap width when renovating the altitude at the edge, it is basically also possible to have the cone in the lower one To reinforce the area of the threshold block, as in the second embodiment 2 (first inclined section 4b). Through this training at Height correction ensures that at least in this area the lateral surfaces be completely backfilled with the renovation material. It is advantageous that there is a minimum grouting joint of at least 5 mm to ensure a full-surface Ensure backfilling of the contact surface as well as in the lower area of the lateral surface.

The aforementioned renovation or height correction can be done in a simple, time-saving and can thus be carried out cost-effectively. This allows the work mentioned can be carried out in short pauses and thus high availability the railway line can be reached.

Such renovations can be systematically prepared according to prepared procedures uniform spare parts.
