Definitions
- the invention relates to a method for producing a track construction according to the preamble of claim 1.
- a method can be, for example, a Track superstructure produce, using a solid roadway with roadway material at least one rail having two rails and in which the rails at least with a rail foot in a respective Longitudinal recess of the lane taken and in it at least partially continuously insulated / elastically mounted with insulated / elastic Support the rails down and to the side over elastic material.
- a track superstructure a concrete slab of a solid Road with trough-like recesses (troughs) by a paver produced.
- these recesses are the (not by tie rods connected) rails (for example railroad tracks or tram rails) placed and at a distance from the trough bottom and in the distance adjusted from the trough sidewalls using Unterkeilungs / wedging elements made of cork.
- Cork is used because of this material favorable, namely damping transmission properties for has the transmission of structure-borne noise on the concrete slab.
- a disadvantage of this production method and on this rail system is that in practice the concrete slab by the paver or not at the most cost-effective with so much costly effort can be, as would be desirable. You will therefore often choose the trough-like recesses slightly larger and must, if necessary also rework manually. This has the consequence that comparatively large Amounts required by the relatively expensive cork-elastic potting compound are. The manual rework also has the consequence that no ideal trough with smooth vertical trough walls is present. It therefore becomes a gearing come between the casting material and the concrete. In this case the rails can only be changed badly. The latter will especially in curve areas usually in comparatively shorter Intervals may be required.
- the invention has the object, a method for Production of a track construction (possibly a track superstructure) as at the beginning described, which is less expensive and / or reproducible Delivers results.
- a method for Production of a track construction possibly a track superstructure as at the beginning described, which is less expensive and / or reproducible Delivers results.
- the object underlying the invention is achieved according to claim 1 essentially in that the Rails positioned before formation of the support layer according to a desired track layout and substantially continuously along the rail longitudinal extent with the Dämm slaughterung be provided, the latter the rail and Rail bridge essentially completely enveloped and a Rail casing forms, from which the rail head projects upwards. Thereafter, the support layer between the ground and the bottom of the Dämm slaughterung and around the Dämm harshung around shaped and Bonding brought.
- the rails can be easily positioned and adjusted if necessary as they are not yet arranged in longitudinal recesses or the like.
- the support layer are.
- a gearing between insulating layer and supporting layer, the one Replacing the rails would make it difficult to prevent or it can be a defined, possibly with regard to a position of the Rails desired interlocking between insulating layer and supporting layer be purposefully brought about. All you need is insulation to have a corresponding surface on which the Support layer material is brought to the plant.
- the material used Dämm Anlagenungsmaterial or elastic coating material is exact controllable, since no material is required, too large gaps between them between a finished support layer and the rails fill.
- the Dämm harshung can Moreover, a defined lateral support or defined Unterlagerung the rails are reached via the Dämm harshung, since the malleable Support layer material in forming the support layer to the outer shape the Dämm harshung can adapt. So, for example, do you want to lengthwise a rail track everywhere identical support conditions and / or Insulation conditions (damping conditions) and / or suspension conditions for the rails, so you can easily achieve that along the rail, the insulation layer identical is trained. Conversely, you can also specifically different Support conditions or insulation conditions (damping conditions) or set suspension conditions for the rails, the For example, for curve sections and straight sections differ.
- the supporting layer the example of concrete, asphalt, asphaltic concrete or bulk material with a curable portion of hardening material, such as adhesive material, can easily - depending on the material used - to the Dämm slaughterung around potted or shaped. Is the support layer material sufficiently flowable, so will automatically for one Proper investment of the flowable support layer material at the Dämm slaughterung or possibly an intended at this intermediate layer taken care of.
- the rails are spaced above a ground for the Support layer placed and adjusted for height, track and direction before the support layer material is introduced or the support layer is formed.
- the substrate may be a base course, such as a concrete base course, act or the planum of any track substructure.
- the conventional solid-roadway layer construction with an antifreeze layer, a hydraulically bound support layer and a concrete support plate is possible.
- the concrete support plate may be identical to the support layer, or the support layer may be one on a previously manufactured one Concrete support plate applied additional layer (preferably also a concrete layer) act.
- the underground can be be any stable ground on which a track construction is built can be.
- the construction of the underground will depend on what for a track construction it is, so if it is a Tram track construction or around a railway track construction is. In the latter case, it will depend on what speed or / and for which loads (passenger trains and / or Freight trains) the track construction is designed.
- At least partially (possibly removable) Intermediate layer are used, the outside of the insulation layering is attached or attached and when molding the Support layer, the support layer material at a distance from the Dämm harshung holds.
- the intermediate layer can be provided for this purpose Insulation layering before the action of the formable support layer material to protect, for example, when the support layer material contains water and the insulation layer is sensitive to water.
- a removable intermediate layer may also be provided, for example, that in the case of backing material that shrinks on setting defined cracks achieved between backing layer and insulation layer, which then with a suitable filling material can be filled by pouring. This is usually less expensive than if you have any shrinkage with wants to fill a filling compound; this is often a larger one Apparative effort be required to bring in pressing.
- the moldable support layer material when forming the backing layer in immediate abutment laterally and from below to the insulation layer or the intermediate layer covering it to be brought. This results in the advantages mentioned with regard to defined bearing of the rail and defined positive locking Intervention (toothing) or non-engagement between support layer on the one hand and insulating layer or intermediate layer on the other.
- the form a respective rail casing may be the rail foot or at least a lower portion of a Rail substantially completely wrap and extends preferably at least just below a railhead. So that Sheath moldings during molding of the backing layer in place and Stay in place, for example, by the itself to the shell moldings suppressed backing layer compound not suspended and from the rails are detached, it is particularly useful when the sheathing moldings glued to the rails. This also prevents one hand reliably the penetration of water between the rail and the shell molding and on the other hand serves to increase the longitudinal forces between rail and sheathing.
- the shell moldings offer great advantages: This can be particularly simple defined support conditions and / or suspension conditions or / and damping conditions and a defined Achieve sound insulation for the rails, since the sheathing moldings can be preformed in a defined manner. You can also without further produce a rail casing, the cross-sectional areas with different material properties, in particular different elastic properties and / or support properties. It is also possible shell moldings with different Cross sections, but still identical elastic properties and / or support properties. Of course can also be along by providing different cross sections the rail route changing elastic properties or / and support properties be set.
- a maximum material savings can be achieved.
- Such an outer shape of the rail casing but has the disadvantage that the rails can not be replaced so easily, for example because the rail casing over a large area of the support layer is overruled.
- the rail casing in Cross section is substantially rectangular or square or that the Rail casing tapers in cross-section downwards, preferably forming side surfaces of the rail casing, the not from the support layer or only at least one defined Fixing projection to be overlapped.
- the latter training of Rail casing with downwardly tapering cross section particularly advantageous, since in this way the rails together with their rail casing particularly easy from longitudinal recesses in the support layer can be lifted, which is reflected in the shaping of the support layer to the rail casing under investment of support layer material to the Forming rail sheathing surface.
- a security against unintentional, taking place during operation lifting the rails together with their rail casing from the Lssensaus traditions can be achieved in that said at least one fixing projection is provided, the rail sheathing in the longitudinal recesses (Troughs) stops.
- the fixing projection is designed in this way that in case of replacement of the rails, the rails together with their Rail casing nevertheless without much effort from the Lssensaus fundamentalungen the support layer can be removed.
- the rail casing at least one of the hardened support layer overlapped Side projection, in particular at least one of a side surface the jacket has projecting longitudinal ridge, preferably such that by applying lifting forces on the rail together with the rail casing the side projection with the support layer in the manner of L Kunststoffs a locking connection can be disengaged.
- At least one of a shell molding attached or attachable or with this one-piece cover lip or Abdecklasche is provided, which is a transition between the Rail casing and the adjacent support layer covered. For example, this can cause ingress of water between Rail casing and supporting layer can be prevented.
- the rail casing To support longitudinal forces coming from the rails on the rail casing be transferred and from the rail casing on the support layer to be transferred, the rail casing at least in regions, an outer surface having a transverse structure, for example, a sole having a transverse structure and / or a lateral structure having a lateral structure.
- a pressure sensitive adhesive on the outside attach the rail casing (the Dämm slaughterung), for example just before forming the support layer, so that an adhesive or adhesive Connection between supporting layer and rail casing (insulation layering) arises.
- the rails may be at a different location opposite the track construction site the insulation layering, possibly rail sheath, be provided.
- the Rails can be encased in the factory, for example, for example, by the rail manufacturer. You can do the rails but also only at the track construction site with the insulation layering, if necessary Rail casing, provided.
- the rails may be endless rails, wherein corresponding individual rails before storage of the same on the ground or on a rail holding the rails at a distance above the ground Holding assembly welded to endless rails. But you can also the rails as single rails first on the ground or on a holding arrangement at a distance above the ground holding the rail Approximately in position and only then to endless rails weld.
- any Outline deviations or deviations in shape of the rails to the Welds can in the case of prefabricated shell moldings simply be compensated by that on the inside of the shell moldings corresponding sections cut away or burned / melted away become.
- the rail casing directly on the rail for example by means of a Rails ummanteinden, possibly encapsulating cladding machine, the For example, have a movable along the rail sliding formwork could, such form deviations are automatically compensated.
- Such, from at least one formed directly on the rail Sheathing molding existing rail casing also has the great advantage that a seamless cladding of the rail (except the rail running profile) with the elastic material or insulating material (with the insulation layering or elastic layering) is possible. The usage Therefore, such a wrapping method is not limited to the case of Limited to endless rails.
- Separate track holding elements preferably made from the rails Concrete, metal or plastic, to be used on the ground or be placed at a distance above the ground with which the with the insulation layering, possibly the rail casing, provided Rails are brought into positive engagement and around the the Support layer material and thus the support layer is formed around.
- the track holding elements do not need it be designed, the occurring by rail operating forces (Operating pressures) record and endure. Rather, the Support the rails to the side and down primarily or alone over the insulation layering and the supporting layer take place.
- the track holding elements So only need an adjustment and fixing function during manufacture meet the support layer.
- the lane-holding elements are also made reinforced to the loads to withstand an emergency operation.
- the lane-holding elements may be assigned to the two rails, preferably have engagement sections designed as receiving cavities, with which the respective rail casing in positive engagement is brought.
- the rails may be relative to each other before forming the support layer, in particular with regard to the correct gauge and / or the inclination of the Rails to each other, adjusted and then relative to each other and possibly relative to the track holding elements are fixed, possibly by wedging / wedging of the rails in the receiving troughs.
- the rail casing and the track holding elements including the formation of the engaging sections, if necessary receiving troughs be coordinated with each other so that by manufacturing the positive engagement between the attached to the rails Jackets and the track holding elements at their engagement portions a self-adjustment of the rails relative to each other, in particular as regards the correct gauge and / or the inclination of the rails to each other (equivalent taper). In a sense, you need the rails with the rail casing only into the receiving troughs, to get a track-adjusted track.
- the track holding elements may be such that with them as well desired track constrictions / track extensions (for example in narrow bends) can be realized by, for example, the position of the Sheath receiving recesses relative to each other variable is. It is also conceivable that the recesses for the sheathing something wider, then with different spacers the to set the desired track.
- lane-holding elements can one before the introduction of the support layer material or the molding of the Support layer on the rails of the respective track at least one Put on touch-track rod, which during the molding of the support layer Transmitted to the rails transversal forces and so the rails in a desired relative position holds (about a lateral tilting of the rails prevents) and which, preferably after setting of the support layer material, is removed again.
- a filling material in particular a Glue or / and water protection mass
- Another advantageous possibility is not covered by the support layer material Surface areas of the insulation layering (rail sheathing if necessary) after setting of the support layer material with a covering compound, in particular gluing or / and water protection mass, cover.
- At least one cover in particular cover lip or cover flap, on a surface not covered by the backing layer material Insulation layering (possibly rail sheathing) and / or on a supporting layer surface attached, possibly glued, which is a transition between the insulation layer and the adjacent support layer covered, in particular for preventing ingress of water between Insulation layering and supporting layer.
- the insulation layering possibly the Sheath moldings, protect against the action of water or / and a penetration of water between the rail casing and the counteract solidified support layer material or / and the rails together the rail casing against lifting from the respective longitudinal recess secure and / or longitudinal forces from the rail-rail shroud arrangement transferred to the support layer.
- a particularly great advantage of the proposed tracking elements is in that the rails of the track, preferably after adjustment in terms of gauge (if required), but in any case before Forms of the support layer, simply according to track layout and / or Exaggeration and / or pitch can be adjusted, namely by appropriate Einjust réelle the tracking elements.
- the rails a track thus maintain their positioning relative to each other. you can thus adjust the track gauge and / or the equivalent Taper or, more generally, the relative positioning of the two Rails to each other by the Einjust réelle the track profile course or separate the cant or pitch.

In the embodiment of FIG. 18, these are in Cross-section dovetail-shaped, with a particularly strong toothing with the supporting layer to be formed around the shell molding to reach.
- the rail casing with respect to a rail longitudinal section one or more parts, can be decided according to expediency become. So it may be with regard to a simple, inexpensive manufacturing often be useful, the rail casing based on a rail longitudinal section multipart, for example, with several Coating moldings. This is especially true when different Materials are used.
- the one rail longitudinal section associated components can at least in part be connected before wrapping the rail, For example, glued together or otherwise, For example, by positive engagement, be connected to each other. It is but also possible that the or some of the components (sheath molding) only connected in the course of wrapping the rail be glued together, for example, or in mutual Interlocking be brought.
- the components can also indirectly, connected by the rail, for example by gluing the used components to the rail or / and be brought into positive engagement with the rail.
- a "temporary" connecting the components for example, by means of adhesive tapes or the like sufficient to the Components during the molding of the support layer in its desired position to hold relative to each other and relative to the rail, as after completion the supporting layer usually subordinates the components under the mediation Support layer should be held together.
- FIG. 19 An example of a multi-part rail casing and a so can be produced track construction is shown in Fig. 19.
- the chamber fillers Although elastic, but essentially not or only slightly Compressible, because solid rubber under pressure its volume in the essentially retains and the force exerted by elastic evasion seeks to absorb.
- the chamber fillers 40m-1 and 40m-2 can each have a longitudinally extending, the rail bridge 26m open recess 160m have to adapt to the packing serve to the manufacturing tolerances of the rail.
- the chamber filling body For example, they can be vulcanized from scrap tires or rubber granules Be body.
- the chamber fillers In the manufacture of the track construction, the chamber fillers preferably glued to the rail, especially the rail web. Assign the chamber fillers to their left or right surface Transverse profiling, so acting on the rail longitudinal forces be supported.
