Description

sleeper

The present invention relates to a threshold sheeting, in particular for a railway sleepers carried in a ballast bed, a method for producing a Schwellenfersohlung and a railway sleepers made of concrete.

US 7,278,588 B2 discloses a sleeper pad. In addition to a planar basic body, this threshold filling also comprises web-like projections projecting vertically from the basic body, which are configured roof-shaped or mushroom-shaped on their front side.

DE 10 2004 01 1 610 A1 likewise discloses a planar basic body with a surface modification consisting of dimples or rib-shaped elevations, at the end of which a mushroom-shaped or bent end is arranged.

AT 506 529 B1 discloses a method for assembling a first layer and a second layer. It is provided that the first and the second layer are respectively provided and then joined together by a roller, that is, the first layer is arranged and fixed on the second layer.

A sleeper pad, also called underside pad (USP), is an elastic layer arranged on the underside of railway sleepers, in particular concrete sleepers. The (elastic) sleeper padding allows adaptation to the ballast bed, resulting in increased wing area and reduced tion of the gravel or the gravel grains leads. In particular, the compressive stress of the ballast, especially in the contact area between the threshold and the ballast, can be reduced because the contact area is increased insofar as it allows the ballast grains to penetrate into the sleeper bottoming. For example, threshold solders known in the art are adhered to the railway sleeper. The disadvantage here is the additional effort in sleeper and low adhesion. Furthermore, threshold solders with adhesive systems, for example with undercuts, holes and intermediate spaces, etc., are known, which are pressed into the still soft concrete (the railway sleeper). After curing, a positive connection is formed with the threshold insole. Such threshold solders are produced by casting or by extrusion, and the abovementioned adhesive systems must be elaborately formed, which is expensive and time-consuming.

It is therefore an object of the present invention, a Schwellenloyohlung, in particular for a worn in the ballast bed sill, a method for producing a threshold insole and a railway sleepers made of concrete, to which a Schwellenleohlung is attached, which eliminate the aforementioned disadvantages.

This object is achieved by a Schwellenhleohlung according to claim 1, a method according to claim 1 1 and by a railway sleeper according to claim 15. Further advantages and features will become apparent from the dependent claims and the description and the accompanying figures.

According to the invention, a threshold insole, in particular for a railway sleeper supported in a ballast bed, comprises a first layer and a second layer, wherein the first layer is disposed on the second layer, and wherein by the first layer an adhesive system for mounting / attachment to a Railroad tie is formed. The second layer is the layer which, when installed, is oriented towards the ballast bed. The first layer is accordingly oriented towards the concrete sleeper. Preferably, therefore, one (at least) two-layered, two-layer structure of the threshold soling originally from at least two separate layers or elements. The adhesive system is characterized by the fact that it can form a positive connection with the material of the railway sleeper, in particular with the concrete. The at least two-layered construction advantageously makes possible a separate production and in particular also a separate handling of the two layers, which considerably simplifies the manufacturing process of the threshold soling, which will be discussed in more detail below. According to one embodiment, the first layer is attached to the second layer, in particular form and / or material and / or non-positive. The fastening is preferably carried out by a pressing and / or gluing method. Typical pressures are in a range of about 0.01 to 500 bar. The abovementioned processes can also be carried out under the action of temperature, with typical temperatures preferably being in a range from about 20 to 300.degree. C., preferably from 80 to 280.degree. Optionally, during bonding, in particular during the compression, the first and second layers, not only the connection of the first and second layer but also the vulcanization of the first and / or the second layer take place, which allows a further degree of freedom in the manufacture of the Schwellenloyohlung , It should be noted at this point that the two layers can consist of the same material or of different materials.

According to a preferred embodiment, the first layer comprises at least one profile element, in particular a strip, or the first layer is formed as a profile element. This embodiment has proved to be particularly advantageous, since such a profile element can be very effectively prepared for example by means of an extrusion or injection molding. According to a preferred embodiment, a plurality of profile elements is provided, wherein the profile elements are expediently arranged substantially parallel to one another. This multiplicity of profile elements forms suitable moderately the first layer and in this way advantageously forms the adhesive system for the arrangement or attachment of the threshold insole at the railway sleeper. According to a preferred embodiment, the threshold soling is positioned at the railway sleeper in such a way that the profiled elements extend substantially transversely to a longitudinal direction of the railway sleeper, in other words in the track direction. Alternatively, however, a positioning transversely to the track direction (along the railway sleeper) is possible, or else an "oblique" positioning, for example in a range of about 30 to 60 °, in particular about 45 °, with respect to the track direction.

According to one embodiment, the profile element has an arrangement area and an adhesion area, wherein the adhesion area is designed such that it extends in particular substantially perpendicularly away from the second layer, in particular at an angle between 80 ° and 100 °. But it is also possible to orient the adhesive area at a smaller or larger angle to the second layer. The arrangement region is provided in particular for arranging or fastening the profile element to the second layer. For this purpose, the arrangement region expediently comprises an arrangement surface or a contact surface, which then bears against the second layer. The main function of the adhesive area is to provide a geometry over which ultimately the, in particular form-fitting, connection with the concrete sleeper is made possible. For this purpose, the adhesion region advantageously extends substantially perpendicularly away from the second layer or from the arrangement region. In cross section, such a profile element essentially has the shape of a T-beam.

Conveniently, a ratio of a height of the profile element to a width of the arrangement region is about 1 to 3, preferably about 1, 2 to 1, 5. It has been found that such a relationship creates an optimum compromise between the stability of the connection between the first and second layers and the bonding strength between the first layer and the concrete sleeper. A thickness / wall thickness of the adhesion region is in preferred embodiments about 1 to 5 mm, more preferably about 1, 5 to 3 mm. The same applies to a thickness / wall thickness of the arrangement area.

It has been found that with the abovementioned geometries it is possible to achieve a very good bond strength between the railway sleeper and the sleeper reinforcement. If, for example, the adhesive system is made too thick or voluminous, good adhesive strength may possibly be achieved, but due to the high use of material and the resulting higher production costs, this approach is not expedient. If the wall thicknesses of the adhesive system and in particular the adhesion region or the arrangement region are too thin, sufficient adhesive strength can not be achieved. With the aforementioned dimensions and sizes, an adhesive strength between the railway sleeper and the sleeper padding of greater than 0.4 MPa can be achieved, wherein the bond strength, for example, in CEN / TC 256 / SC 1 / WG 16 / SG 4 (Annex E) is described. In fact, the values / requirements mentioned there are even clearly exceeded with the embodiments proposed here.

According to an alternative embodiment, the arrangement region is also not formed "wider" than the adhesion region, which means that the profile element has the shape of an "1" carrier in cross-section A thickness of the adhesion region or a width of the arrangement region is in these embodiments, in order to allow sufficient adhesion, in a range of about 2 to 15 mm, in particular from about 5 to 10 mm.

Expediently, in order to ensure adequate adhesion, about 5 to 20 profile elements are arranged over a length of 10 cm, preferably about 10 to 17, the measuring direction being transverse to the longitudinal direction of the profile elements. In preferred embodiments, a distance of the profile elements in a range of about 3 to 20 mm, preferably about 5 to 12 mm. The profile elements preferably have a constant cross section along their longitudinal direction. Conveniently, the profile elements extend substantially straight along their longitudinal direction. Alternatively, a wave or zigzag shape may be advantageous to increase the surface area of the adhesion as well as the placement area.

An embodiment has been described above in which the adhesion region extends substantially perpendicularly away from the arrangement region or from the second layer. The adhesive area is thus essentially perpendicular to the concrete sleeper. Alternatively, the adhesion region can extend at an angle not equal to 90 °, for example in a range of approximately 20 to 70 °, in particular in a range of approximately 30 to 45 °, relative to the arrangement region or the concrete sleeper. By this geometry can be formed with advantage, solely by the positioning / inclination of the profile elements, undercuts or recesses for the concrete. The profile elements can be arranged so that they are all inclined in the same direction, alternatively they can also, for example alternately, be inclined in different directions.

The adhesive region, which has hitherto been described as a substantially straight web, can also have a wave or zigzag shape, perpendicular to the second layer, in order, if appropriate, to influence the adhesion with the concrete. A wave or zigzag shape may alternatively or additionally also extend substantially parallel to the second layer. The fact that the first layer or the profile elements are produced separately from the second layer, the geometry of the first layer (as well as the second layer) are very many possibilities, which, however, do not increase the cost of the manufacturing process itself.

According to a preferred embodiment, the profile element, or in particular the adhesion region, at least one recess, preferably a plurality of recesses, which is arranged along the longitudinal direction of the profile element. These recesses can take a variety of forms, such as round, insbesondre circular, oval, square, such as square or rectangular, triangular, etc.

In particular, it is provided that the profile element is closed on the side facing away from the second layer, d. H. an upper side facing away from the second layer forms a continuous contour. In other words, the profile element is not open in the mounted state on the side facing the concrete sleeper. As a result, when tying the threshold, the liquid concrete must first flow around or surround the profile element in order to reach the recess. As a result, can provide a particularly stable and resistant form-fitting in the assembled state. According to a further embodiment of the present invention, it is provided that the profile element is formed leiterformig with the recesses. In such an embodiment, transversely extending rungs are provided between two web portions extending in the longitudinal direction. The area between the rungs then preferably form the recess. Due to the ladder-like design, it is advantageously possible for the rungs to be stabilized in their position or alignment with the web region facing away from the second layer. As a result, the profile element is strengthened in an advantageous manner. This proves to be advantageous, for example, when pouring in the liquid concrete, since the likelihood of the profile element being bent over is reduced.

Preferably, the distance between two rungs seen in the longitudinal direction is constant. Such a profile element can be realized comparatively easily. However, it is also conceivable that the distances change seen in the longitudinal direction, for example, periodically increase and then decrease again.

Furthermore, it is preferably provided that the recess is larger in the longitudinal direction than an extension of the profile element in a direction perpendicular to the longitudinal direction. direction extending transverse direction. Preferably, the expansion of the profile element is 0.2 to 0, 8 times, preferably 0.3 to 0.75 times and particularly preferably 0.45 to 0.65 times as large as the extent of the recess in the longitudinal direction , For the ratio between 0.45 to 0.65 results in a profile element whose top is comparatively narrow compared to the recess. This simplifies the inflow of the liquid concrete into the recesses when connecting the threshold insole to the railway sleeper.

In particular, it is provided that the second layer comprises a recess. Preferably, the recess has a closed cross section, so that the recess forms a hollow region or cavity.

According to a further embodiment, it is preferably provided that the profile element in addition to the recess at its end facing away from the first layer end has a roof-shaped, mushroom-shaped and / or cap-shaped conclusion. As a result, the positive connection of the concrete with the Schwellenigungsohlung can be further enhanced in an advantageous manner.

Conveniently, the at least one recess forms an opening which extends substantially parallel to the second layer, in other words preferably transversely to the adhesion region. In particular, when the adhesion region extends substantially perpendicular to the second layer, the provision of such recesses is particularly recommended in order to provide the required adhesive strength. Furthermore, it is also possible to form the adhesive region with an undercut, for example by having at its distal end a cross-sectional enlargement, for example in the form of a transverse rib.

According to a preferred embodiment, the recesses substantially in the form of squares, with a side length of about 3 to 6 mm, in particular about 4 mm. In this case, these recesses / squares, with respect to their midpoints or center lines, are preferably arranged at a distance of approximately 5 to 7 mm, particularly preferably approximately 6 mm. According to preferred embodiments, the first layer and the second layer are formed from plastic. The first layer is formed, for example, from a thermoplastic, for example from PE (polyethylene), PE-UHMW (ultra-high molecular weight polyethylene), PP (propylene), PET (polyethylene terephthalate), PPT (polypropylene terephthalate), PA (polyamide), EVA ( Ethylene vinyl acetate), PUR (polyurethane or elastomer granules). In this case, the first layer may be formed from a solid material or from a foam material. The second layer is preferably also made of a thermoplastic, in particular PE (polyethylene), PE-UHMW (ultra-high molecular weight polyethylene), PP (propylene), PET (polyethylene terephthalate), PPT (polypropylene terephthalate), PA (polyamide), EVA (ethylene vinyl acetate), PUR (polyurethane) or an elastomer (NR, SBR, EPDM, CR, NBR, BR) and / or blends of these. The second layer can also be formed from a solid material or from a foam material.

Conveniently, a layer thickness of the first layer is in a range of about 0.01 to 18 mm, preferably in a range of 0.05 to 15 mm, particularly preferably in a range of about 0.1 to 10 mm. A layer thickness of the second layer is preferably in a range of about 0.2 to 30 mm, particularly preferably in a range of about 0.5 to 20 mm. The second layer has a hardness, preferably in a range of about 10 ShA to 90 ShD, more preferably in a range of about 20 ShA to 90 ShD. According to one embodiment, the second layer is a rubber which has a hardness range of about 20 ShA to 90 ShD. Both the first and the second layer can be pressed from a rubber granulate. Likewise, they may be produced in a casting process or in an extrusion process.

According to one embodiment, at least the second layer is formed in multiple layers, whereby a targeted modification of their properties is made possible. In particular, for example, the damping behavior can be influenced in a targeted manner by a multilayer structure. The layers may differ, for example, in their thickness or in terms of their material. The layers can NEN be glued together, for example. At least one of the layers can also be formed from a metal material.

In one embodiment, the threshold anneal includes a third one

Layer, in particular on an underside of the second layer, which is attached to the side facing away from the first layer, wherein the third layer is a gravel protection layer. For example, the layer is a fleece or a fabric made of PE, PP, PA, and / or PET. It can also be formed from metal filaments or from films made of PE, PE-UHMW, PP, and / or PTFE. It can also be formed from metal sheets and / or fabrics / meshes.

The invention also relates to a method for producing a Schwellbe- sole, comprising a first layer and a second layer, wherein by the first layer, an adhesive system for mounting / attachment to a railway sleeper is formed, wherein the first layer by a plurality of profile elements is formed, comprising the steps:

Providing the first layer;

Providing the second layer, in particular the profile elements;

Arranging, in particular arranging successively, and fastening the profiled elements on the second layer.

The provision of the profile elements can take place in such a way that the profile element is cut out or punched out of a plate which has been cast or extruded, for example. In particular, it is provided that recesses are punched into the profile element. Preferably, the stamped recess can be used as an adhesive system in the fabricated threshold soling. In the manufacture of the threshold soling or during the transport of the threshold soling, such recesses can also advantageously be used to transport the profile element or the threshold soling, for example by a transporting means engaging in the recess and the profile element or the threshold soling transposed. ported. This proves to be particularly advantageous if the profile element is transported in the longitudinal direction.

The fastening can be, for example, a pressing, in particular a continuous or discontinuous pressing, of the two layers. According to one embodiment, vulcanization of the first and / or the second layer takes place during or after the pressing.

The pressing is carried out, for example, at pressures in a range of about 0.01 to 500 bar and at temperatures in a range of about 20 to 300 ° C. In this respect, during the pressing, the first and / or the second layer can be vulcanized. Preference is given to using continuous vulcanization processes under pressure. Alternatively, the vulcanization, both of the first and the second layer or, where appropriate, of both layers, can also take place after the pressing. The layers may also have been vulcanized prior to compression, for example in a continuous or batch press or extrusion process.

Preferably, the threshold soling is produced in a continuous pressing process, wherein expediently several, possibly also different, materials / layers can be directly connected to one another. The elastomers used may be in the vulcanized and / or unvulcanized state. Moreover, it is possible that the sleeper padding is easily produced in multiple layers with consistent product quality and constant dimensions. In the case of the conventionally used methods (eg PUR casting), this can only be achieved with great effort. Also advantageous is the production by means of step pressing method.

An example of a continuous vulcanization process under pressure is the rotary vulcanization process. This makes it possible to continuously produce products with and without reinforcement inserts. Another example is the double belt presses. These presses consist of two endless steel bands, which are led around two drums. Pressure and temperature can be varied along the flat belts. Compared with rotary vulcanization processes, double belt presses have the advantage that much higher pressures can be achieved. Compared to cutting presses, it is advantageous that the heating and cooling takes place under constant pressure without having to open the press, in order that there are no transient loads with double heating time. As a semi-continuous process, which can also be used in the present case, the lead-coat method is to be mentioned. A raw hose or a raw cable is covered by a lead extruder or a lead press. The thickness of the lead layer is between 1 and 3 mm, for example. Usually, hoses are built on flexible rubber or plastic mandrels. The necessary pressure is created by the difference between the thermal expansion coefficients of lead and rubber or plastic. According to one embodiment, the method further comprises the step:

Transporting the second layer along a transport direction and arrange the profile elements transversely to the transport direction.

This means that the profile elements expediently extend in the installed state transversely to a longitudinal direction of / of the railway sleeper.

According to one embodiment, the method further comprises the step:

Punching the Schwellenhleohlung to the desired level, with the profile elements expediently extend along the longitudinal direction of the railway sleeper.

This step is particularly advantageous because very different and very different dimensions can be realized very quickly and easily. Likewise, the orientation of the profile elements, for example along, transversely or obliquely to the threshold soling, can be adjusted quickly and easily, depending on how the punching process is performed. The invention also relates to a concrete railway sleeper to which a sleeper pad is attached, the sleeper pad having a first layer and a second layer, the first layer being on or at the second layer is arranged and wherein by the first layer an adhesive system for arrangement / attachment to the railway sleeper is formed, in particular for positive connection with the concrete of the railway sleeper. The sleeper reinforcement is fastened to a lower side of the railway sleeper, the tracks run on top of the railway sleepers. The bond strength between the sleeper and the sleeper tie is described, for example, in CEN / TC 256 / SC 1 / WG 16 / SG 4 (Annes E) and in the present case reaches values greater than 0.4 MPa.

For the railway sleepers according to the invention and for the method according to the invention, the advantages and features already mentioned within the scope of the embodiments for sleeper padding apply analogously and correspondingly, and vice versa.

Further advantages and features will become apparent from the following description of preferred embodiments of the invention, the threshold Schüssle solving, the method and the railway sleeper, with reference to the accompanying figures. Individual features of the individual embodiments can be combined with each other within the scope of the invention.
