Definitions

  • the invention relates to an embedded rail for rail vehicles, comprising a rail which has a rail head, a rail foot and at least one rail chamber, as well as an embedding trough and a chamber filling element made of an elastic material which surrounds the rail at least laterally in regions and with the rail the embedding trough is arranged.
  • the WO 03/012203 A2 teaches a rail assembly in which the rail is housed in an inner shell and this inner shell is again received in an outer shell.
  • the rail is detachably received in the inner shell, which is designed as a precast concrete or steel part.
  • US 5,788,153 describes a rail fastening, which is arranged in a groove and in which a Kammer hypollelement is fixed by a wedge-shaped with a screw in the groove fixed wedge element between the rail chamber and inner wall of the embedding channel.
  • the invention / innovation is based on the object to embed a rail for rail vehicles so that it is easy to assemble, can be dismantled in a simple manner and the components used for this purpose are both inexpensive to produce, as well as environmentally friendly recyclable and / or reusable.
  • This object is achieved by the features of claim 1 and the Method claim 15 solved.
  • At least a portion of the Kammer circallenses is formed on at least one side of the rail as a holding portion and can be fixed by a from above in or on the holding portion retractable expansion element between the rail chamber and the inner wall of the embedding channel for fixing the rail , Only by the introduction of the expansion element, the holding element is fixed so that this inhibits the rail in case of unwanted movements. For example, intentional movements may represent a defined compression of the rail under load.
  • the expansion element can be driven from above into or onto the holding section. This means that the expansion element can penetrate both into a holding element, as well as that the expansion element can exert its fixing effect on contact points of two or more holding elements.
  • the holding element may also consist of several components which are at least partially in driving the expansion element in contact with it.
  • a spreading element which fixes the holding sections, which in turn hold the rail, offers a high degree of assembly and disassembly comfort and allows the assembly and disassembly to be carried out within a very short time.
  • a rail connection which can be optionally dissolved again without destruction, an economical and environmentally friendly - because at least partially reusable - possibility.
  • the lateral legs of the U-profile are in the final assembled state below the highest point of the rail head and the side legs of the profile in the final assembly state above the lower half of the rail .
  • the rail can be laid, for example, in a concrete bed, since the rail is arranged in the embedding channel and this in turn is embedded in the concrete bed.
  • the attack surface of the concrete is increased and thus the stability of the embedding trough and the rail positively influenced.
  • the stabilization can be further increased by the lateral legs of the U-profile are in the final assembly state below the highest point of the rail head. A sufficient minimum stability is achieved if the lateral limbs of the U-profile are in the final assembly state above the lower half of the rail.
  • a further advantageous measure is when the embedding channel has at least one engagement element on at least one of its inwardly directed walls, which engages with a corresponding counter element of the holding section and / or with an anchor element contacting the holding section.
  • Such an engagement element may for example represent a recess, opening or a highlighting of the embedding trough, which enters into a positive connection with a corresponding counterpart of the holding portion and / or the anchor element.
  • the expansion element does not necessarily have the holding section at least in final assembly position actively brace.
  • the expansion element can passively, ie positively prevent, loosen the two connection partners.
  • a superimposed positive and positive action of the expansion element on the retaining element allows a particularly good guarantee of the fixing function.
  • the holding of the rail on the holding portions is further enhanced by the holding elements provided with spreading elements are arranged on both sides of the rail and, for example, in pairs opposite.
  • the holding portion has a SpreizelementausEnglishung.
  • the cross-sectional contour of the expansion element may have undercuts, which prevents unintentional release of the expansion element, for example a drop-shaped or diamond-shaped cross-sectional contour.
  • the cross-sectional contour of the expansion element has a sawtooth-like shape at least in regions, wherein the outwardly pointing solder of the slope points in part to the bottom region of the embedding trough.
  • the expansion element in the final assembly state (for example, the expansion element to be arranged completely in the expansion element recess) to terminate flush with the upper edge of the chamber filling element.
  • the flush termination makes it possible to build the holding section as high as possible and at the same time to take up the spreader entirely.
  • the expansion element can also engage in the manner of a dowel in the holding portion.
  • the expansion element formed plate-like and corresponds in length approximately the length of the holding portion.
  • the expansion element is provided with at least one arranged in the region of its top or end face engagement grooves.
  • Such engagement recesses preferably have undercuts behind which, for example, special tools such as pliers can engage and thus facilitate release via a larger lever or a larger engagement surface.
  • the engagement recess is formed as a bore provided with an internal thread, into which a provided with a corresponding external thread tool is screwed and then the retaining element can be removed from the mounted state via the threaded connection.
  • the engagement recess is provided with a cover or is sprayed with a releasable foam, so that can not accumulate over the life of the rail environmental deposits in the engagement recess, which in turn could hinder the attachment of tools.
  • a further advantageous embodiment has at least two (on each end face in each case at least one) opposite engagement recesses on the end faces, which can go, for example, with a pair of pliers in engagement and thus the holding portion can be removed.
  • the anchor element protrudes through an opening of the embedding channel and is anchored in the final assembly position outside of the embedding channel.
  • the anchor element both a positive engagement with the opening of the embedding trough, as well as with the surrounding the embedding trough material (eg concrete). Due to the positive engagement of the anchor element with the material surrounding the embedding trough, the embedding trough is simultaneously fixed within the surrounding material.
  • the anchor element engages in a recess of the embedding trough and the embedding trough forms a positive connection via an emphasis and / or a recess with the building material (concrete) surrounding the embedding trough.
  • An advantage of this embodiment is that when dismantling the anchor element can be removed more easily, since this is arranged only in a recess of the embedding trough and is not glued to the building material, where appropriate.
  • the anchor element is preferably configured such that it has at least two different cross-sectional areas.
  • a cross-sectional area corresponds with its outer contour, for example with the recess, opening or highlighting of the embedding trough and can thereby cause a rotation of the anchor element.
