Definitions
- the invention relates to a slab track for rail-bound traffic, as described in the preamble of claim 1.
- This carriageway has a track grate, the sleepers of which are vertically movable by means of dowel-like devices, but are anchored practically immovably in the sleeper axis on the support plate of the carriageway.
- the invention has set itself the task of further developing a slab track of the type described above so that the economic disadvantages of the previously required special rail fastening are eliminated.
- the limited possibility of deflection of the rail on the sleeper with the standard rail fastening is to be expanded by the more economical feasibility of larger spring travel with the help of spring elements arranged under the sleeper.
- the storage of the track grate according to the invention achieves a safe vertical deflection of the track, which has considerable advantages over the previous solution with deflection directly under the rail foot and is considerably more economical.
- the solution according to the invention is only possible with a vertically overall elastic or freely moveable mounting of the threshold on the base layer, as is known, for example, in the case of the slab track known from EP 0 637 645, in which the dowels of the sleepers on the base layer also have vertical movements the threshold allows relative to the base course.
- the vibrating mass By moving the spring from the rail foot to the sleeper base, the vibrating mass is increased by the sleeper mass. The vibration is damped faster and noise emissions are reduced.
- the threshold can be statically dimensioned with smaller dimensions and / or less reinforcement by punctiform, direct transmission of the vertical track load from the rail to the base course.
- the proposed design of a slab track enables simple, high-precision pre-assembly of the bearings in the sleeper plant during the manufacture of the sleepers. This reduces the effort for height adjustment on the construction site accordingly.
- Pollyurethane for example, would be suitable as a material for bearings made of elastomer foam, and chloroprene rubber for bearings made of solid material.
- the bearings can also be designed as composite elements, for example steel plates with vulcanized rubber, as is customary in bridge construction for deformation bearings.
- the bearings must be set so that they experience a 1-1.5 mm drop under a certain axle load. In the total weight of the directly supported track grating required for the positional stability of the track, sleepers with the previous standard dimensions and a minimum weight of 350 kg / sleeper are required.
- the stiffness of the bearings under the sleepers can be increased in the direction of the rails towards the sleeper edges.
- the restoring moments are increased because of the larger inner lever arms (larger core widths of the bearing cross-sections) these are combined into a storage unit by composite panels made of another material, for example steel, which facilitates assembly and also allows protrusions beyond the threshold.
- Height corrections of the track grate are usually carried out by relining the rail on the threshold.
- the bearings under the sleepers can also be increased by inserting additional bearing plates.
- these compensation plates must be made of hard materials such as steel, hard rubber, etc.
- the ties that have been anchored to the concrete base layer either have to be added to the dowel blocks or replaced with higher dowel blocks.
- the important equivalence of the proposed slab track with the classic ballast track with regard to airborne noise emission can also be achieved without absorbers placed on the sleepers if the sleepers are ballasted with a damping bulk material (e.g. from recycling material from concrete demolition). In this case, it must be prevented that hard foreign bodies immigrate into the gap between the threshold and the base course, which prevent the threshold from deflecting.
- the gap around the bearings and dowel elements can be filled with a soft foam that does not absorb water due to the risk of frost (e.g. closed-pore elastomer foam, foam rubber).
- frost e.g. closed-pore elastomer foam, foam rubber
- a sleeper 3 with a dowel 24 is held horizontally immovable and vertically movable on the base layer 1 in the sleeper axis.
- spring elements according to the invention are arranged approximately as a point-shaped bearing 6 of the threshold, approximately in the axis of the rails.
- the track grate made of sleepers 3 and rails 4 fastened thereon with a rail fastening 5 are placed on the bearings 6.
- the bearing 6 consists of a plate 7, which in the example shown has anchoring elements integrally connected to it in a wart-like manner.
- the anchoring elements 8 engage in corresponding recesses 10 on the underside of the threshold 3.
- the joint 9 between the plate 7 of the bearing 6 with the anchoring elements 8 is closed with a suitable mortar and thereby the plate 7 is connected to the threshold 3 with the correct position and height.
- This step is expediently already carried out during the production of sleepers in the sleepers factory.
- With the anchoring elements 8, a positive connection between the plate 7 and the concrete of the sleeper 3 is achieved, which transfers shear forces even if the adhesive joint between the bearing and the sleeper fails.
- FIG 3 shows an expedient embodiment of the bearing 6 with a plate 11 according to claim 8 with staggered growing force-transmitting cross sections 11/1, 11/2, 11/3.
- the plate areas depending on their load-bearing cross-sectional areas 11/1, 11/2, 11/3, make different contributions which are inversely proportional to their size, so that the total deformation progressively decreases with increasing load.
- Figure 2 shows a slab track in which soundproofing elements 12 according to claim 9 are mounted on the sleepers 3.
- the reduction in the dimension of the threshold 3 by using the weight of the soundproofing elements 12 according to claim 9 is indicated by the length 13 reduced in FIG. 2 compared to the normal threshold length 14.
- Height corrections of the track e.g. when the support layer 1 settles, it can be achieved in a simple manner by filling the bearing 6 or 23 with bearing supplement plates 15.
- the plates 15 can have securing strips 16, by means of which the plates are prevented from moving relative to the bearing. 4 shows the example of a bearing with bearing strips 23.
- a bearing constructed from bearing strips 23 can be combined expediently and to simplify assembly by means of a composite plate 17 to form a bearing unit 18.
- the sound emission of the track can be reduced in addition to soundproofing elements 12 by filling the compartments 19 between the sleepers 3 with loose bulk material 20.
- the gap 21 between the base layer 1 and the threshold 3 must be sealed against the ingress of foreign bodies, particularly from the bulk material.
- a suitable means 22 for sealing the gap 21 can be aging-resistant, closed-pore elastomer foam.

Abstract
Description
Die Erfindung betrifft eine Feste Fahrbahn für schienengebundenen Verkehr, wie sie im Oberbegriff des Anspruchs 1 beschrieben ist. Diese Fahrbahn weist einen Gleisrost auf, dessen Schwellen durch dübelartige Vorrichtungen vertikal beweglich, jedoch in Schwellenachse praktisch unverschiebbar aufder Tragplatte der Fahrbahn verankert sind.The invention relates to a slab track for rail-bound traffic, as described in the preamble of claim 1. This carriageway has a track grate, the sleepers of which are vertically movable by means of dowel-like devices, but are anchored practically immovably in the sleeper axis on the support plate of the carriageway.
Derartige Feste Fahrbahnen sind beispielsweise aus der EP 0 637 645 bekannt. Bei dieser Festen Fahrbahn wird ein Gleisrost aus Schienen und Schwellen auf einer Tragschicht verlegt, wobei zwischen Schwellen und Tragschicht eine nachgiebige Schicht verlegt ist, die punktuelle Ungleichmäßigkeiten zwischen der Oberfläche der Tragschicht und den Sohlflächen der Schwellen ausgleichen und aus derartigen Ungleichmäßigkeiten evtl. entstehende Spannungsspitzen abbauen soll. Diese Ausgleichsschicht hat keine definierten elastischen Eigenschaften und trägt nur in zu vernachlässigender Größenordnung zur vertikalen Einfederung des Gleisrostes bei. Horizontal wird der Gleisrost durch elastische Dübelelemente, wie sie aus der EP 0 637 645 bekannt sind, auf der Tragschicht fixiert.Fixed carriageways of this type are known, for example, from EP 0 637 645. In this slab track, a track grate made of rails and sleepers is laid on a base course, with a flexible layer being laid between the sleepers and the base course, which compensates for punctual irregularities between the surface of the base course and the base surfaces of the sleepers and reduces any voltage peaks that may arise from such irregularities should. This leveling layer has no defined elastic properties and only contributes to the vertical deflection of the track grating to a negligible extent. The track grating is fixed horizontally on the base layer by elastic dowel elements, as are known from EP 0 637 645.
Um die aus betriebs- und fahrtechnischen Gründen erforderliche elastisch gedämpfte Abfederung des Gleises, die bei herkömmlichen geschotterten Gleisen durch die Schotterung gegeben ist, auch bei Festen Fahrbahnen zu erreichen, werden die Schienen auf Festen Fahrbahnen durch ein Schienenbefestigungssystem gehalten, bei dem eine verhältnismäßig dicke elastisch nachgiebige Zwischenplatte unter dem Schienenfuß eingebaut ist. Diese Platte allein unter dem Schienenfuß verlegt würde sehr große Kippbewegungen der Schiene bei entsprechender Belastung zulassen, durch die die Betriebssicherheit beeinträchtigt werden könnte.In order to achieve the elastically damped cushioning of the track required for operational and technical reasons, which is given by the ballast in conventional ballasted tracks, even on slab tracks, the slides are held on slab tracks by a rail fastening system, in which a relatively thick elastic flexible intermediate plate is installed under the rail foot. This plate, laid alone under the rail foot, would permit very large tilting movements of the rail under the appropriate load, which could impair operational safety.
Um die Einfederungseigenschaften für die Schiene bei der weichen Schienenauflagerung des Gleises auf der Schwelle bei Festen Fahrbahnen in einer Größenordnung zu erreichen, wie sie bei Schotterbettung üblich ist, wurde eine Schienenbefestigung für Feste Fahrbahnen entwickelt, die den Schienenfuß über dem Auflager mit Hilfe einer Stahlplatte verbreitert (vgl. Ioarv 300 der Deutschen Bundesbahn). Dadurch werden beim Kippen der Schiene die Kantenpressungen auf der elastischen Zwischenplatte und die Einsenkung der Platte und damit die Schienenkippung entsprechend verringert. Diese Schienenbefestigung ist durch die erforderliche Stahlplatte, erheblich vergrößerte Winkelführungsplatten und eine vergrößerte Zwischenplatte sehr aufwendig und beeinträchtigt die Wirtschaftlichkeit der gesamten Konstruktion dieser Festen Fahrbahn.In order to achieve the deflection properties for the rail in the soft rail support of the track on the sleeper on slab tracks of a magnitude that is common with ballast bedding, a rail attachment for slab tracks was developed, which widens the rail foot above the support with the help of a steel plate (see Ioarv 300 of the Deutsche Bundesbahn). As a result, when the rail is tilted, the edge pressures on the elastic intermediate plate and the depression of the plate and thus the rail tilting are correspondingly reduced. This rail fastening is very complex due to the required steel plate, considerably enlarged angle guide plates and an enlarged intermediate plate and affects the economy of the entire construction of this slab track.
Die Erfindung hat sich die Aufgabe gestellt, eine Feste Fahrbahn der oben beschriebenen Gattung so weiter zu entwickeln, daß die wirtschaftlichen Nachteile der bisher erforderlichen besonderen Schienenbefestigung entfallen. Die begrenzte Möglichkeit der Einfederung der Schiene auf der Schwelle bei der Standard-Schienenbefestigung soll durch die wirtschaftlichere Machbarkeit größerer Federwege mit Hilfe von unter der Schwelle angeordneten Federelementen erweitert werden.The invention has set itself the task of further developing a slab track of the type described above so that the economic disadvantages of the previously required special rail fastening are eliminated. The limited possibility of deflection of the rail on the sleeper with the standard rail fastening is to be expanded by the more economical feasibility of larger spring travel with the help of spring elements arranged under the sleeper.
Die Aufgabe wird gelöst durch eine Feste Fahrbahn, wie sie im kennzeichnenden Merkmal des Anspruchs 1 beschrieben ist. Ausgestaltungen der Erfindung geben die Ansprüche 2 - 9 an.The object is achieved by a slab track as described in the characterizing feature of claim 1. Embodiments of the invention specify claims 2-9.
Durch die erfindungsgemäße Lagerung des Gleisrostes wird eine sichere vertikale Einfederung des Gleises erreicht, die gegenüber der bisherigen Lösung mit Einfederung direkt unter dem Schienenfuß erhebliche Vorteile aufweist und wesentlich wirtschaftlicher ist. Die erfindungsgemäße Lösung ist jedoch nur möglich bei einer vertikal insgesamt elastischen oder frei beweglichen Lagerung der Schwelle auf der Tragschicht, wie sie beispielsweise bei der aus EP 0 637 645 bekannten Festen Fahrbahn bekannt ist, bei der auch die Verdübelung der Schwellen auf der Tragschicht vertikale Bewegungen der Schwelle relativ zur Tragschicht zuläßt.The storage of the track grate according to the invention achieves a safe vertical deflection of the track, which has considerable advantages over the previous solution with deflection directly under the rail foot and is considerably more economical. However, the solution according to the invention is only possible with a vertically overall elastic or freely moveable mounting of the threshold on the base layer, as is known, for example, in the case of the slab track known from EP 0 637 645, in which the dowels of the sleepers on the base layer also have vertical movements the threshold allows relative to the base course.
Durch die Verlagerung der Feder vom Schienenfuß zur Schwellensohle wird die schwingende Masse um die Schwellenmasse vergrößert. Die Schwingung wird schneller gedämpft und die Lärmemission vermindert.By moving the spring from the rail foot to the sleeper base, the vibrating mass is increased by the sleeper mass. The vibration is damped faster and noise emissions are reduced.
Durch punktförmige, unmittelbare Übertragung der vertikalen Gleislast aus der Schiene in die Tragschicht kann die Schwelle statisch mit geringeren Abmessungen und/oder geringerer Bewehrung bemessen werden.The threshold can be statically dimensioned with smaller dimensions and / or less reinforcement by punctiform, direct transmission of the vertical track load from the rail to the base course.
Die vorgeschlagene Bauart einer Festen Fahrbahn ermöglicht eine einfache, höhengenaue Vormontage der Lager bereits im Schwellenwerk bei der Herstellung der Schwellen. Damit sinkt der Aufwand für den Höhenausgleich aufder Baustelle entsprechend.The proposed design of a slab track enables simple, high-precision pre-assembly of the bearings in the sleeper plant during the manufacture of the sleepers. This reduces the effort for height adjustment on the construction site accordingly.
Als Material für Lager aus Elastomereschaum würde sich z.B. Pollyurethan eignen, für Lager aus Vollmaterial Chloroprene-Kautschuk. Die Lager können auch als Verbundelemente, z.B. Stahlplatten mit aufvulkanisiertem Gummi, wie im Brückenbau bei Verformungslagern üblich, ausgeführt werden. Die Lager müssen so eingestellt sein, daß sie unter einer bestimmten anzunehmenden Achslast eine Einsenkung von 1-1,5 mm erfahren. In dem für die Lagestabilität des Gleises geforderten Gesamtgewicht des direkt aufgelagerten Gleisrostes sind Schwellen mit den bisherigen Standardabmessungen und einem Mindestgewicht von 350 kg/Schwelle erforderlich. Bei Verwendung geeigneter, auf den Schwellen aufgelagerter Schallschutzelemente, wie sie zum Lärmschutz bei Hochleistungsstrecken der Bahn ohnehin gefordert werden und beispielsweise in den unveröffentlichten DE 195 17 384.8 , DE 195 29 754.7, DE 195 35 880.5 und DE 195 37 621.8 beschrieben sind, kann bei abgemindertem Schwellengewicht als Folge einer günstigeren, direkten Lastabtragung bei der erfindungsgemäßen Festen Fahrbahn durch Heranziehung des Gewichts der Schallschutzelemente die Gewichtsminderung der Schwellen ausgeglichen werden.Pollyurethane, for example, would be suitable as a material for bearings made of elastomer foam, and chloroprene rubber for bearings made of solid material. The bearings can also be designed as composite elements, for example steel plates with vulcanized rubber, as is customary in bridge construction for deformation bearings. The bearings must be set so that they experience a 1-1.5 mm drop under a certain axle load. In the total weight of the directly supported track grating required for the positional stability of the track, sleepers with the previous standard dimensions and a minimum weight of 350 kg / sleeper are required. When using suitable soundproofing elements mounted on the sleepers, such as are required for noise protection on high-performance lines of the railway anyway and are described, for example, in the unpublished DE 195 17 384.8, DE 195 29 754.7, DE 195 35 880.5 and DE 195 37 621.8, can with reduced threshold weight as a result of a more favorable, direct load transfer in the slab track according to the invention, the weight reduction of the thresholds can be compensated for by using the weight of the soundproofing elements.
Um die Kippneigung der Schwellen beim Angriff von Kräften in Schienenrichtung, z.B. beim Sonderlastfall Schienenbruch", zu verringern, kann die Steifigkeit der Lager unter den Schwellen in Schienenrichtung zu den Schwellenrändern hin vergrößert werden. Die Rückstellmomente werden dadurch wegen der größeren inneren Hebelarme (größere Kernweiten der Lagerquerschnitte) erhöht. Werden im Extremfall der Steifigkeitverteilung geteilte Lagerstreifen verwendet, können diese durch Verbundplatten aus einem anderem Material , z.B. Stahl, zu einer Lagereinheit zusammengefaßt werden, was die Montage erleichtert und auch Überstände über die Schwelle erlaubt.About the tendency of the sleepers to tilt when forces are applied in the direction of the rail, e.g. in the event of a special load Rail breakage ", the stiffness of the bearings under the sleepers can be increased in the direction of the rails towards the sleeper edges. The restoring moments are increased because of the larger inner lever arms (larger core widths of the bearing cross-sections) these are combined into a storage unit by composite panels made of another material, for example steel, which facilitates assembly and also allows protrusions beyond the threshold.
Höhehkorrekturen des Gleisrostes, die z.B. aus Setzungen des Baugrundes herühren können, werden im Regelfall durch Unterfüttern der Schiene auf der Schwelle ausgeführt. Reichen diese Möglichkeiten jedoch nicht aus, können auch die Lager unter den Schwellen durch Einschub von Lagerergänzungsplatten erhöht werden. Um die Einfederung der Lager nicht zu verändern, müssen diese Ausgleichsplatten aus harten Materialien, wie Stahl, Hartgummi usw. sein. In diesem Fall müssen bei den Schwellen, die mit der Betontragschicht verdübelt sind, entweder die Dübelsteine aufgestockt werden oder durch höhere Dübelsteine ersetzt werden.Height corrections of the track grate, e.g. can result from subsidence of the subsoil, are usually carried out by relining the rail on the threshold. However, if these options are not sufficient, the bearings under the sleepers can also be increased by inserting additional bearing plates. In order not to change the deflection of the bearings, these compensation plates must be made of hard materials such as steel, hard rubber, etc. In this case, the ties that have been anchored to the concrete base layer either have to be added to the dowel blocks or replaced with higher dowel blocks.
Die wichtige Gleichwertigkeit der vorgeschlagenen Festen Fahrbahn mit dem klassischen Schottergleis hinsichtlich der Luftschallemission kann auch ohne auf die Schwellen aufgelegte Absorber erreicht werden, wenn die Schwellen mit einem dämpfenden Schüttgut (z.B. aus Recyclingmaterial aus Betonabbruch) eingeschottert werden. In diesem Fall muß verhindert werden, daß harte Fremdkörper in den Spalt zwischen Schwelle und Tragschicht einwandern, die das Einfedern der Schwelle verhindern. Dazu kann der Spalt um die Lager und Dübelelemente vollflächig mit einem weichen Schaum, der wegen der Frostgefahr kein Wasser aufnimmt (z.B. geschlossenporiger Elastomereschaum, Moosgummi) aufgefüttert werden. In gleicher Weise können Abklebungen oder Kittfugen nur am Schwellenrand verwendet werden. Dann muß für eine dauerhaft wirksame Entwässerung des Spaltes gesorgt werden.The important equivalence of the proposed slab track with the classic ballast track with regard to airborne noise emission can also be achieved without absorbers placed on the sleepers if the sleepers are ballasted with a damping bulk material (e.g. from recycling material from concrete demolition). In this case, it must be prevented that hard foreign bodies immigrate into the gap between the threshold and the base course, which prevent the threshold from deflecting. The gap around the bearings and dowel elements can be filled with a soft foam that does not absorb water due to the risk of frost (e.g. closed-pore elastomer foam, foam rubber). In the same way, tapes or putty joints can only be used on the threshold edge. Then a permanently effective drainage of the gap must be ensured.

Auf einer erfindungegemäßen Fahrbahn ist eine Schwelle 3 mit einem Dübel 24 in Schwellenachse horizontal unverschieblich und vertikal beweglich auf der Tragschicht 1 gehalten. Auf der Oberfläche 2 der Tragschicht 1 sind etwa in der Achse der Schienen erfindungsgemäße Federelemente als punktförmige Lager 6 der Schwelle angeordnet. Auf den Lagern 6 ist der Gleisrost aus Schwellen 3 und darauf mit einer Schienenbefestigung 5 befestigten Schienen 4 aufgelegt. Das Lager 6 besteht aus einer Platte 7, die im gezeigten Beispiel warzenförmig mit ihr einstückig verbundene Verankerungselemente aufweist. Die Verankerungselemente 8 greifen in entsprechende Ausnehmungen 10 auf der Unterseite der Schwelle 3 ein. Die Fuge 9 zwischen der Platte 7 des Lagers 6 mit den Verankerungselementen 8 wird mit einem geeigneten Mörtel geschlossen und dadurch die Platte 7 mit der Schwelle 3 lage- und höhengenau verbunden. Dieser Arbeitsgang wird zweckmäßig bereits bei der Schwellenfertigung in der Schwellenfabrik durchgeführt. Mit den Verankerungselementen 8 wird eine formschlüssige Verbindung zwischen der Platte 7 und dem Beton der Schwelle 3 erreicht, die auch bei Versagen der Klebefuge zwischen Lager und Schwelle Schubkräfte überträgt.On a roadway according to the invention, a
