    专利说明:

    The invention relates to a rail foot casing which is designed as a profile and has a support section and lateral profile sections.
    Such rail foot coatings are known per se. In the case of a solid track that is continuously supported, the rail foot of a rail, which is cast in concrete, is covered with an elastic material. A rubber material is usually used for this.
    From DE 203 04 291 U1 a rail foot casing is known which surrounds a rail foot. The rail foot casing comprises a support section on which the underside of the rail foot rests, as well as lateral profile sections which surround the rail foot. Below the rail foot casing there is an intermediate layer, a base plate and another intermediate plate which is arranged on a concrete body.
    In DE 20 2005 004 870 U1, an elastic profile for sheathing a rail foot is proposed, the support section of which is designed as a hollow profile and has several cavities.
    In certain applications, in particular in slab tracks for trams with small curve radii, comparatively high horizontal force components occur. With such a load there is the possibility of tilting and / or twisting of the rail due to the rail foot sheathing made of the elastic material. On the other hand, an elastic mounting of the rail is necessary and desirable so that the solid track formed therefrom has a certain deflection in the vertical direction.
    The invention is therefore based on the object of specifying a rail foot sheathing which, on the one hand, enables a certain vertical deflection and, on the other hand, allows only limited horizontal movement.
    To solve this problem, the invention provides for a rail foot sheathing of the type mentioned that at least the side profile sections are made of a material whose modulus of elasticity is at least 100 MPa, d. H. 100 N / mm <2>.
    The invention is based on the knowledge that the desired elastic behavior can be achieved by using at least for the lateral profile sections a material whose modulus of elasticity is significantly greater than the modulus of elasticity of conventional materials used for this purpose. Until now, rubber-like, that is to say elastomeric materials, for example EPDM, have usually been used. However, the modulus of elasticity of such materials is a maximum of 30 MPa, which results in the aforementioned low horizontal rigidity. The invention is thus based on the idea that the horizontal guidance of the rail foot can be improved if the lateral profile sections are made from a material with a greater modulus of elasticity. The lateral profile sections can preferably be made of a plastic material which is more rigid than a rubber material.
    A particularly preferred embodiment of the rail foot casing according to the invention provides that the support section and the lateral profile sections are made of different materials and are connected to one another. This results in the possibility of designing the elastic properties of the rail foot casing according to the invention differently in the vertical direction and in the horizontal direction by using different materials for the lateral profile sections and the support section. A material with a low modulus of elasticity, for example a rubber material (elastomer material) such as EPDM, which has a modulus of elasticity of 30 MPa or less, can thus be used for the support section, similar to conventional rail foot sheathing. In contrast to this, the side profile sections are made of a different material whose modulus of elasticity is 100 MPa or more. The components of the rail foot sheathing, that is, the lateral profile sections and the support section, can be manufactured separately and then connected to one another. However, rail casings can also be produced in which the two components are connected to one another in a one-step production process, for example an extrusion process or an injection molding process.
    According to a further development of the rail foot casing according to the invention, it can be provided that the support section and the lateral profile sections are glued to one another. It is particularly preferred that between the undersides of the lateral profile sections and the top of the support section adhesive surfaces are formed. In principle, it is also conceivable that the connection between the support section and the lateral profile sections is produced by another joining method, for example by a welding method, by vulcanization or the like.
    The rail foot sheathing according to the invention can also be designed so that the support section and the lateral profile sections are positively connected to one another. It is preferred that either the support section or the lateral profile sections have at least one protrusion and the other component has at least one correspondingly oppositely designed recess into which the at least one protrusion can be inserted. The projections can also be designed as knobs which engage in corresponding recesses of the other component. Finally, a variant is also conceivable in which the support section has lateral recesses which form pockets into which lower sections of the lateral profile sections engage.
    In a further embodiment of the invention it can be provided that the lateral profile sections have an essentially constant thickness. This shape allows the side profile sections to be produced as an endless material, for example by extrusion.
    While the previously explained embodiments of the rail foot casing according to the invention provide that two different materials are used, it can alternatively be provided according to a particularly preferred embodiment of the invention that the rail foot casing is formed in one piece and has at least one section with a reduced material thickness. For example, the rail foot sheathing can have a section with a reduced cross section or reduced thickness in its central region. This geometric shape has the effect that the rail foot casing has a reduced stiffness in the area of the section, which makes it possible to elastically deform the rail foot casing for mounting on a rail foot by enlarging the opening formed between the two free ends of the profile sections for inserting the rail foot. After the rail foot has been inserted, the rail foot casing surrounds the corresponding contact surfaces of the rail foot with its lateral profile sections in a form-fitting manner.
    In a rail foot sheathing according to the invention designed in this way, it is particularly preferred that, apart from the section having the reduced cross section, it has an essentially constant thickness. Such a profile, which has the section with a reduced cross-section, also enables production in a continuous, endless process, for example by extrusion.
    In the rail foot sheathing according to the invention, it is preferred that the lateral profile sections are shaped so that they surround a rail foot in a form-fitting manner.
    According to the invention it can be provided that the rail foot casing has a length between 500 mm and 5000 mm, preferably between 1000 mm and 2000 mm.
    Preferably, a component made of an elastomeric material and designed as an intermediate layer is arranged on the support section, on which the rail foot stands in the assembled state. The intermediate layer thus forms a support surface for the rail foot.
    The invention is explained below using exemplary embodiments with reference to the drawings. The drawings are schematic representations and show: FIG. 1 a first exemplary embodiment of a rail foot casing according to the invention attached to a rail; FIG. 2 shows the rail foot sheathing shown in FIG. 1 during assembly; FIG. 3 shows a detail of a lateral profile section when glued to a support section; 4 shows an exemplary embodiment of a rail foot sheathing according to the invention with a form fit; 5 shows a further embodiment of a rail foot casing according to the invention in the assembled state; FIG. 6 shows a view of the rail foot casing from FIG. 5 in the longitudinal direction; FIG. FIG. 7 shows a detail of the rail foot casing shown in FIG. 6; FIG. 8 is a perspective view of the rail foot casing of FIG. 6; 9 shows a further exemplary embodiment with several rail foot sheaths attached to a rail; 10 shows a further exemplary embodiment with several rail foot sheaths attached to a rail; FIG. 11 shows another exemplary embodiment of a rail foot sheath according to the invention; and FIG. 12 shows a further exemplary embodiment of a rail foot casing according to the invention.
    Fig. 1 is a sectional view and shows an embodiment of a rail foot casing 1, which is designed as a profile and surrounds a rail foot 2 of a rail 3 for a tram. The rail foot casing 1 comprises a support section 4 and lateral profile sections 5, 6. In this exemplary embodiment, the lateral profile sections 5, 6 are produced separately and then connected to the support section 4. The lateral profile sections 5, 6 consist of a plastic material whose modulus of elasticity is at least 100 MPa. It is the material PVC. In contrast, the support section 4 consists of a rubber material, in the illustrated embodiment it is EPDM. Alternatively, z. B. closed-cell PUR or mixed-cell PUR can be used, the z. B. under the name Sylodyn <®> or Sylomer <®> is available. Between the lower sides 7 of the lateral profile sections 5, 6 and the upper side 8 of the support section 4, adhesive surfaces 9 provided with adhesive are formed. The lateral profile sections 5, 6 are firmly connected to the support section 4 by the adhesive, which prevents relative displacement, in particular in the lateral direction. In Fig. 1 it can be seen that the lateral profile sections 5, 6 encompass the rail foot 2 in a form-fitting manner. In the assembled state, the lateral profile sections 5, 6 are acted upon by tension clamps or other rail fastening components, whereby the rail 3 is pressed elastically by the support section 4 of the rail foot casing against a rail support area of a concrete sleeper (not shown).
    The lateral profile sections 5, 6 are laterally beyond the support section 4. This protrusion can be, for example, 2 to 25 mm. The thickness of the support section 4 can be 9 to 12 mm, for example. The thickness of the lateral profile sections 5, 6 can be, for example, 0.5 to 3.0 mm.
    As already mentioned, the side profile sections 5, 6 and the support section 4 are made of different materials, the support section 4 made of the elastomer EPDM and the side profile sections 5, 6 made of PVC or an equivalent material. This material has a modulus of elasticity which is at least 100 MPa, whereby a very good lateral hold of the rail 3 is guaranteed, even when z. B. with tight curve radii considerable horizontal force components occur. The rail foot cladding 1 thus ensures better lateral horizontal guidance of the rail 3 compared to a conventional rail foot cladding; in particular, a tilting movement or a rotary movement of the rail 3 under load is significantly reduced. By selecting a support section 4 with a certain thickness, the vertical elasticity of the rail foot casing 1 can be adjusted. By defining the thickness of the lateral profile sections 5, 6, the elasticity of the rail foot casing 1 can be influenced in the horizontal direction. Thus, the elastic behavior in both load directions can be influenced and adjusted largely independently of one another.
    Fig. 2 is a view similar to Fig. 1 and shows the rail foot casing 1 when it is being fastened to the rail foot 2 of the rail 3. For this purpose, a central area of the support section 4 is stretched and elastically deformed so that an the lateral profile sections 5, 6 formed free space is increased considerably. Due to the elasticity of the rubber material from which the support section 4 is made, its central area can be stretched considerably, for example to twice its length. In the view shown in FIG. 2, it is thus possible to introduce a lateral end of the rail foot 2 into the free space 12 formed by the lateral profile section 6. The support section 4 then returns elastically to its initial state, so that the state shown in FIG. 1 results.
    Fig. 3 shows a detail of the rail foot casing 1, wherein an outer portion of the support section 4, the lateral profile section 6 and the adhesive surfaces 9 are shown on which the lateral profile section 6 is positioned, as by the arrow shown in FIG 13 is indicated. Gluing the lateral profile section 6 to the support section 4 results in the two-part rail foot casing 1.
    4 shows a detail of a further exemplary embodiment of a rail foot casing 14, the support section 15 of which has circular through openings 16 which extend in the longitudinal direction of the rail and are spaced apart from one another. Projections formed as knobs 17 engage in these through openings 16 and are located on the underside of a lateral profile section 18. In FIG. 4 it is shown that the free end of the knobs 17 is spaced apart from the underside of the support section 15. The free space 19 formed thereby enables the rail 3 to be deflected without the knobs 17 touching a rail support area of a concrete sleeper. In this embodiment, the rail foot sheathing 14 thus consists of the lateral profile sections 18 and the support section 15, which can either be provided as separate components or also be preassembled in advance. In a variant it can be provided that the profile sections having knobs are glued to the support section. Gluing is not absolutely necessary, however.
    An alternative variant of the embodiment shown in Fig. 4 provides that the knobs are arranged on the top of the lateral profile section and thus on the inside of the rail foot casing. The elastic intermediate layer can then - unlike shown in FIG. 4 - above the lateral profile section having the knobs, ie. H. be arranged on the inside of the rail foot casing.
    5 to 8 show a further embodiment of a rail foot casing 20, FIG. 5 showing the rail foot casing 20 after it has been attached to the rail 3, FIG. 6 is a view of the rail foot casing 20 in the longitudinal direction, FIG. 7 shows a detail of the rail foot casing 20 in the area of a reduction in cross section and FIG. 8 is a perspective view of the rail foot casing 20.
    The rail foot casing 20 is designed as a profile and comprises a support section 21 and lateral profile sections 22, 23. The rail foot casing 20 is designed as a one-piece, integral component and consists of a single material. It is a material with a modulus of elasticity of at least 100 MPa. To this extent, this material corresponds to the material from which the lateral profile sections 5, 6 of FIG. 1 are made. It is made of PVC or an equivalent material with a modulus of elasticity greater than 100 MPa.
    In Fig. 6 it can be seen that the support section 21 of the rail foot casing 20 has a section 24 with a reduced material thickness. In this exemplary embodiment, the section 24 is located in the middle between the two lateral ends of the support section 21.
    Fig. 7 shows a detail of the support section 21 and the reduced cross-section having section 24. Between the support section 21 and the section 24 with reduced material thickness, a ramp-shaped transition region 25 is formed over which the thickness is reduced. This cross-sectional reduction reduces the rigidity of the rail foot sheathing 20, so that it can be elastically bent open for mounting on the rail foot 2 in order to insert the rail foot 2. The rail foot sheathing 20 then resiliently resumes its original shape, which is shown in FIGS. 5 and 6.
    In Fig. 5 it can be seen that the vertical extension of the rail foot casing 20 is chosen so that a free space is formed between the underside of the rail 3 and the support portion 21, in which an elastic component, which is designed as an intermediate layer 26 and from an elastomeric material is used.
    9 is a perspective view of a further exemplary embodiment and shows the rail 3 on which a plurality of rail foot sheaths 1 are arranged in the longitudinal direction. Either an adhesive seam 27 is provided between two rail foot sheaths 1 arranged next to one another in the longitudinal direction, alternatively an overlap 28 is provided between two adjacent rail foot sheaths 1. In both cases, a sealing of the rail foot casing 1 is achieved, whereby the penetration of dirt and / or moisture is prevented.
    10 is a perspective view of a further exemplary embodiment and shows the rail 3 as well as several rail foot casings 1. It can be seen that a chamber filling element (chamber element) 29 is arranged on the side of the rail 3. In FIG. 10, only a single chamber filling element 29 is shown; it goes without saying that a plurality of chamber elements 29 are arranged in the longitudinal direction of the rail 3. In addition, a sheathing 30 for the rail web and the rail head of the rail 3 is shown as an example. In the assembled state, several casings 30 arranged next to one another are similarly present. The chamber filling elements 29 and the casings 30 are arranged on both sides of the rail 3.
    11 shows a further exemplary embodiment of a rail foot casing 31 which is constructed similarly to the rail foot casing 1 shown in FIG. The rail foot cladding 31 comprises a support section 32 and lateral profile sections 33, 34. The rail foot cladding 31 surrounds a rail foot 35 of a rail 36 which has a movable tongue 37. Such tongue devices are used in the area of a switch in order to divide the rail into two parts. The width of the rail foot casing 31, i.e. H. the distance between the two profile sections 33, 34 is adapted to the width of the rail foot 35 in each case. The rail foot casing 31 can thus be produced in different sizes and lengths.
    Fig. 12 shows a further embodiment of a rail foot casing 40 with the support section 32 and the profile sections 33, 34. Deviating from the previous embodiment, the rail foot casing 40 comprises two juxtaposed rail feet 38, 39. The structure shown in Fig. 12 is also referred to as "4-rail track" and is used for advanced switch devices and track oscillations.
