Abstract

In a rail support structure (3) with preferably sound-insulating rail bases (5), arranged at specific distances from one another under a rail (2) in the longitudinal direction of the latter, each rail base has a foundation-forming bottom plate (6) preferably made of concrete, a carrier plate (7) carrying the rails and, preferably, insulating elements (8) arranged between the bottom plate and the carrier plate and preferably consisting of elastic material. The bottom plate and carrier plate are provided on the sides facing one another with mutually complementary widenings (9) or recesses (10) extending in the longitudinal direction of the rail, and the widenings and recesses preferably possess mutually associated flanks extending in the longitudinal direction of the rail and inclined relative to the horizontal. The insulating elements, if present, are designed and/or arranged in accordance with the widenings or recesses and are preferably arranged only between adjacent flanks of the widenings and recesses. Further sources of interfering frequencies which are located where trains roll over individual support points are eliminated if the distances between the rail bases are very small, preferably equal to zero. <IMAGE>

Description

Die Erfindung betrifft einen Schienenunterbau nach dem Oberbegriff von Anspruch 1 bzw. Anspruch 3.The invention relates to a rail substructure according to the preamble of claim 1 and claim 3.

Hier und im folgenden wird unter einer Schiene der einzelne Schienenstrang verstanden, während normalerweise zwei parallel verlaufende Schienen auf einem Schienenunterbau ein Gleis bilden. Mit einem solchen Schienenunterbau aus Beton od. dgl. befaßt sich die Erfindung.Here and in the following, a rail is understood to mean the individual rail track, while normally two parallel rails form a track on a rail substructure. The invention is concerned with such a rail substructure made of concrete or the like.

Übliche Schienenunterbauten weisen für die im Nahverkehr üblichen Höchstgeschwindigkeiten von 60 km/h in Abständen von etwa 0,6 bis 0,7 m angeordnete schalldämmende Schienenunterlagen auf, die jeweils aus einer Grundplatte, einer Tragplatte und zwischen der Grundplatte und der Tragplatte angeordneten Dämmelementen bestehen (GB-A-2 024 289, GB-A-2 008 176). Die einander zugewandten Oberflächen der Grundplatte und der Tragplatte weisen zueinander komplementär ausgebildete Aufweitungen bzw. Ausnehmungen mit gegenüber der Waagerechten geneigten Flanken auf. Die Dämmelemente sind den Aufweitungen bzw. Ausnehmungen angepaßt und häufig nur zwischen anliegenden, gegenüber der Waagerechten geneigten Flanken angeordnet, so daß zwischen der Grundplatte und der Tragplatte Hohlräume bestehen bleiben. Dadurch wird erreicht, daß die Dämmelemente durch die in vertikaler Richtung einwirkenden Kräfte sowohl auf Druck als auch auf Schub beansprucht werden, so daß eine große statische Einfederung und damit einer gute Körperschalldämmung der Schienenunterlage erzielt wird. Die Ausnehmung in der Grundplatte ist hier regelmäßig im wesentlichen rechteckig ausgeführt, also allseits mehr oder weniger geschlossen, wobei in die Ausnehmung die Tragplatte selbst mit ihren geneigten Flanken eingesetzt wird.Conventional rail substructures have sound-absorbing rail underlays for the maximum speeds of 60 km / h that are common in local traffic at intervals of about 0.6 to 0.7 m, each consisting of a base plate, a support plate and insulation elements arranged between the base plate and the support plate ( GB-A-2 024 289, GB-A-2 008 176). The mutually facing surfaces of the base plate and the support plate have mutually complementary widenings or recesses with flanks that are inclined with respect to the horizontal. The insulation elements are adapted to the widenings or recesses and are often only arranged between adjacent flanks which are inclined with respect to the horizontal, so that cavities remain between the base plate and the support plate. It is thereby achieved that the insulating elements are subjected to both pressure and thrust by the forces acting in the vertical direction, so that a large static deflection and thus good structure-borne noise insulation of the rail underlay is achieved. The recess in the base plate is here generally made essentially rectangular, that is to say more or less closed on all sides, the support plate itself with its inclined flanks being inserted into the recess.

Der zuvor erläuterte, bekannte Schienenunterbau bietet nach wie vor Quellen für Störfrequenzen, - Erschütterungsfrequenzen und Schallfrequenzen. Besonders störende Frequenzen im Nahverkehr, insbesondere bei Untergrundbahnen, treten im Bereich von 25 bis 28 Hz auf, da Biege-Eigenfrequenzen von Stahlbeton-Geschoßdecken größerer Gebäude in diesem Frequenzbereich liegen.The previously described, known rail substructure continues to provide sources of interference frequencies, vibration frequencies and sound frequencies. Frequently disturbing frequencies in local traffic, especially in subways, occur in the range from 25 to 28 Hz, since the natural bending frequencies of reinforced concrete floors of larger buildings are in this frequency range.

Ein hinsichtlich der Störfrequenzen weiter verbesserter schotterloser Oberbau für schienengebundene Fahrzeuge (DE-A 2 901 283) zeichnet sich dadurch aus, daß eine entscheidende Quelle für Störfrequenzen, nämlich die Überrollung von Einzelstützpunkten, also einzeln angeordneten Schienenunterlagen, praktisch eliminiert worden ist. Hier sind durchlaufend hintereinander angeordnete Schienenunterlagen verwirklicht, die sowohl als Schwellen als auch als Schotterbett wirken. Beide Schienen eines Gleises befinden sich hier auf ein und derselben Tragplatte in einem festen seitlichen Abstand voneinander. Die Schienen bilden dabei mit der Tragplatte einen einheitlichen Schwingungskörper, dessen Resonanzfrequenz in einem Bereich liegt, der hinsichtlich der Frequenz störend niedrig liegt. Dadurch ist eine störende Quelle für Störfrequenzen vorhanden.A ballast-free superstructure for rail-bound vehicles (DE-A 2 901 283) which is further improved with regard to the interference frequencies is distinguished by the fact that a decisive source of interference frequencies, namely the rollover of individual support points, that is to say individually arranged rail supports, has been practically eliminated. Here, rail supports arranged one behind the other are realized, which act both as sleepers and as a ballast bed. Both rails of a track are here on the same support plate at a fixed lateral distance from each other. The rails form a uniform vibrating body with the support plate, the resonance frequency of which lies in a range which is disturbingly low in terms of frequency. This creates a disturbing source for interference frequencies.

Die Erfindung geht von dem zuletzt erläuterten, bekannten Schienenunterbau aus und soll diesen Schienenunterbau so weiterbilden, daß weitere Quellen für Störfrequenzen bei konstruktiv überzeugender Gestaltung des Schienenunterbaus beseitigt sind.The invention is based on the last-mentioned known rail substructure and is intended to further develop this rail substructure in such a way that further sources of interference frequencies are eliminated with a structurally convincing design of the rail substructure.

Die zuvor aufgezeigte Aufgabe ist in einer ersten Alternative durch die Merkmale des kennzeichnenden Teils von Anspruch 1, in einer zweiten Alternative durch die Merkmale des kennzeichnenden Teils von Anspruch 3 gelöst.The above problem is solved in a first alternative by the features of the characterizing part of claim 1, in a second alternative by the features of the characterizing part of claim 3.

Die kontinuierliche Schienenlagerung bei dem Schienenunterbau, von dem die Erfindung ausgeht, bei dem also die in Längsrichtung der Schienen verlaufenden Aufweitungen und Ausnehmungen benachbarter Schienenunterlagen durchlaufend und praktisch ineinander übergehend ausgeführt sind, hat mit der bekannten Konzeption einer durchgehenden Tragplatte für beide Schienen einerseits das oben erläuterte Störfrequenzproblem, andererseits das Problem erheblichen konstruktiven, nämlich materialmäßigen Aufwandes. Die erfindungsgemäße Konstruktion führt nun unter Beibehaltung des Grundkonzepts der kontinuierlichen Schienenlagerung dazu, daß die Resonanzfrequenz der verbleibenden, von den aufgeteilten Tragplatten und der jeweiligen Schiene eines Gleises gebildeten Schwingungskörper aus dem besonders störenden Niederfrequenzbereich heraus in einen Bereich höherer Frequenzen verlagert wird. Gleichzeitig wird eine erhebliche konstruktive Verbesserung, insbesondere unter Berücksichtigung des Materialverbrauchs realisiert, wobei durch die beanspruchte Gestaltung der Aufweitungen und Ausnehmungen die erforderliche feste Lagerung der Schienen unverändert gewährleistet ist.The continuous rail mounting in the rail substructure from which the invention is based, i.e. in which the widenings and recesses of adjacent rail supports extending in the longitudinal direction of the rails are continuous and practically merging, has the above-described concept of a continuous support plate for both rails Interference frequency problem, on the other hand the problem of considerable constructive, namely material expenditure. The construction according to the invention now leads while maintaining the basic concept the continuous rail mounting means that the resonance frequency of the remaining vibrating bodies formed by the divided support plates and the respective rail of a track is shifted out of the particularly disturbing low-frequency range into a range of higher frequencies. At the same time, a considerable constructive improvement is realized, in particular taking into account the material consumption, the required firm mounting of the rails being guaranteed unchanged by the claimed design of the widenings and recesses.

Die schematische Darstellung in Fig. 1 zeigt ein Gleis 1 aus zwei parallel zueinander verlaufend in festem Abstand voneinander angeordneten Schienen 2, die auf einem gemeinsamen Schienenunterbau 3 mit üblichen Schienenbefestigungsmitteln 4 befestigt sind. Der Schienenunterbau 3 weist unter den Schienen 2 in Längsrichtung der Schienen 2 in bestimmten Abständen voneinander angeordnete Schienenunterlagen 5 auf. Jede Schienenunterlage 5 weist eine ein Fundament bildende Grundplatte 6 sowie jeweils eine eine Schiene 2 tragende Tragplatte 7 auf. Im dargestellten Beispiel besteht die Grundplatte 6 aus Beton, die Tragplatte 7 hingegen aus Stahl.The schematic representation in FIG. 1 shows a track 1 consisting of two rails 2 which run parallel to one another at a fixed distance from one another and which are fastened on a common rail substructure 3 with conventional rail fastening means 4. The rail substructure 3 has under the rails 2 in the longitudinal direction of the rails 2 at certain distances from each other arranged rail pads 5. Each rail support 5 has a base plate 6 forming a foundation and in each case a support plate 7 carrying a rail 2. In the example shown, the base plate 6 is made of concrete, while the support plate 7 is made of steel.

Die weitere Erläuterung der Erfindung anhand der Zeichnung erfolgt anhand einer Zusammenschau von Fig. 1 und Fig. 2 der Zeichnung. Zunächst ist zu erkennen, daß zwischen der Grundplatte 6 und der Tragplatte 7 der Schienenunterlage 5 aus elastischem Material bestehende Dämmelemente 8 angeordnet sind. Weiterhin ist zu erkennen, daß die Grundplatte 6 und die Tragplatte 7 auf den einander zugewandten Seiten mit zueinander komplementär ausgebildeten, in Längsrichtung der Schiene 2 verlaufenden Aufweitungen 9 bzw. Ausnehmungen 10 versehen sind. Die Aufweitungen 9 und Ausnehmungen 10 weisen einander zugeordnete, in Längsrichtung der Schienen 2 verlaufende, gegenüber der Waagerechten geneigte Flanken auf und die Dämmelemente 8 sind den Aufweitungen 9 und Ausnehmungen 10 entsprechend nur zwischen den Flanken der Aufweitungen 9 und Ausnehmungen 10 angeordnet. Wesentlich ist, daß die Dämmelemente 8 durch die erkennbare Ausbildung und Anordnung gleichzeitig auf Druck und auf Schub beansprucht werden, so daß eine ausreichende statische Einfederung gegeben ist und eine optimale Dämmung von Körperschall erreicht wird. Die in Längsrichtung der Schienen 2 verlaufenden Aufweitungen 9 bzw. Ausnehmungen 10 benachbarter Schienenunterlagen 5 sind durchlaufend und, abgesehen von dem u. U. noch vorhandenen geringen Abstand in Längsrichtung ineinander übergehend als durchlaufende Leisten bzw. Wannen ausgeführt.The further explanation of the invention with reference to the drawing is based on an overview of FIG. 1 and FIG. 2 of the drawing. First of all, it can be seen that between the base plate 6 and the support plate 7 of the rail base 5, insulating elements 8 made of elastic material are arranged. Furthermore, it can be seen that the base plate 6 and the support plate 7 are provided on the mutually facing sides with mutually complementary widenings 9 or recesses 10 extending in the longitudinal direction of the rail 2. The widenings 9 and recesses 10 have mutually associated flanks which run in the longitudinal direction of the rails 2 and are inclined with respect to the horizontal, and the insulation elements 8 are arranged according to the widenings 9 and recesses 10 only between the flanks of the widenings 9 and recesses 10. It is essential that the insulating elements 8 are simultaneously subjected to pressure and thrust due to the recognizable design and arrangement, so that there is sufficient static deflection and an optimal insulation of structure-borne noise is achieved. The widening 9 or recesses 10 of adjacent rail supports 5 extending in the longitudinal direction of the rails 2 are continuous and, apart from the u. U. still existing small distance in the longitudinal direction merging into one another as continuous strips or tubs.

Die Erfindung, befaßt sich also mit der Eliminierung der durch Stützpunktüberrollung von Einzelstützpunkten bekannter Schienenunterbauten dargestellten Quellen für Störfrequenzen und eliminiert diese tatsächlich dadurch, daß die Abstände zwischen den Schienenunterlagen 5 sehr gering sind. Im dargestellten Ausführungsbeispiel sind die Abstände zwischen den Schienenunterlagen 5 gleich Null, so daß sich eine insgesamt kontinuierliche, durchlaufende Lagerung der Schiene 2 auf Schienenunterlagen 5 ergibt. Damit fallen Einzelstützpunkte weg, die bislang durch das Auffahren eines überrollenden Rades eines Schienenfahrzeugs auf einen Einzelstützpunkt erzeugte Störung tritt nicht mehr auf.The invention, therefore, is concerned with the elimination of the sources of interference frequencies represented by base rollover of individual base points of known rail substructures and eliminates them actually in that the distances between the rail pads 5 are very small. In the illustrated embodiment, the distances between the rail supports 5 are zero, so that there is an overall continuous, continuous storage of the rail 2 on the rail supports 5. This eliminates the need for individual support points, and the disruption previously caused by the running of a rolling wheel of a rail vehicle onto a single support point no longer occurs.

Im in Fig. 1 dargestellten Ausführungsbeispiel haben die Schienenunterlagen 5 in Längsrichtung der Schiene 2 eine erheblich größere Länge als bislang üblich - bislang übliche Längen zwischen 0,2 m und ca. 0,4 m -, nämlich eine Länge von mindestens 1,5 m, im dargestellten Ausführungsbeispiel von etwa 2 m. Grundsätzlich ist es auch denkbar, daß die Länge der Schienenunterlagen 5 auf die übliche Walzlänge von Schienen abgestimmt wird, das ist jedoch in der Zeichnung nicht dargestellt. Grundsätzlich ist es ferner auch möglich, eine durchgehend langgestreckte, ggf. bis zu 100 m lange oder noch längere Schienenunterlage auszubilden, beispielsweise indem man eine entsprechend langgestreckte Grundplatte als durchgehendes Fundament in Ortsbeton gießt.In the exemplary embodiment shown in FIG. 1, the rail supports 5 have a considerably greater length in the longitudinal direction of the rail 2 than has been customary hitherto - hitherto usual lengths between 0.2 m and approximately 0.4 m - namely a length of at least 1.5 m , in the illustrated embodiment of about 2 m. Basically, it is also conceivable that the length of the rail supports 5 is matched to the usual rolling length of rails, but this is not shown in the drawing. In principle, it is also possible to form a continuously elongated, possibly up to 100 m long or even longer rail support, for example by pouring a correspondingly elongated base plate as a continuous foundation in in-situ concrete.

Eine Tragplatte 7 aus Stahl hat den besonderen Vorteil, daß sie als Stahl-Stranggußprofil oder -Walzprofil ausgeführt sein kann. Im dargestellten Ausführungsbeispiel werden die Tragplatten 7 der Schienenunterlagen 5 einer Schiene 2 durch ein kontinuierlich durchlaufendes Stahlprofil gebildet, das sich über eine Vielzahl von Grundplatten 6 der Schienenunterlagen 5 hinweg erstreckt. Unter Umständen können die die Tragplatten 7 bildenden Stahlprofile endseitig wie die Schienen 2 selbst verschweißt sein.A support plate 7 made of steel has the particular advantage that it can be designed as a continuous steel profile or rolled profile. In the exemplary embodiment shown, the support plates 7 of the rail supports 5 of a rail 2 are formed by a continuously continuous steel profile which extends over a multiplicity of base plates 6 of the rail supports 5. Under certain circumstances, the steel profiles forming the support plates 7 can be welded at the end like the rails 2 themselves.

Fig. 2 zeigt, daß hier die Tragplatte 7 im Querschnitt etwa T-förmig ausgeführt ist.Fig. 2 shows that here the support plate 7 is made approximately T-shaped in cross section.

Fig. 2 zeigt ein Ausführungsbeispiel, bei dem in der Grundplatte 6 jeder Schienenunterlage 5 im wesentlichen symmetrisch unter jeder der Schienen 2 eine einzige, wannenartige Ausnehmung 10 mit einer mindestens etwa der Breite der Schienen 2 am Schienenfuß entsprechenden Breite ausgebildet ist. Anders als bei bekannten Schienenunterlagen, bei denen mehrere zueinander parallel verlaufende Ausnehmungen und Aufweitungen vorgesehen sind, ist hier als kontinuierliche Schienenlagerung eine einzige durchlaufende, wannenartige Ausnehmung 10 vorhanden. Dieser Konstruktion entsprechend ist an der Tragplatte 7 im wesentlichen symmetrisch unter der Schiene 2 eine einzige leistenartige Aufweitung 9 mit einer mindestens etwa der Breite der Schiene 2 am Schienenfuß entsprechenden Breite ausgebildet. Dabei ist hier die Aufweitung 9 im Querschnitt etwas trapezförmig ausgeführt, dem etwa trapezförmigen Querschnitt der Ausnehmung 10 in der Grundplatte 6 entsprechend. Die Breite von Ausnehmung 10 und Aufweitung 9 muß ein Mindestmaß überschreiten, um eine ausreichende Abstützung und eine ausreichende Seitenstabilität der Schienenunterlage 5 zu gewährleisten. Im übrigen führt die vorliegende Querschnittsgestaltung dazu, daß eine wirksame Selbstzentrierung bei überrollendem Rad eines Schienenfahrzeugs erfolgt, so daß die Querauslenkung des Kopfs der Schiene 2 unter Einwirkung von Horizontalkräften (Sinuslauf- und Zentrifugalkräfte) minimal wird.Fig. 2 shows an embodiment in which a single, trough-like recess 10 is formed in the base plate 6 of each rail base 5 substantially symmetrically under each of the rails 2 with a width corresponding at least approximately to the width of the rails 2 on the rail base. In contrast to known rail supports, in which a plurality of recesses and widenings running parallel to one another are provided, a single continuous, trough-like recess 10 is present here as a continuous rail support. According to this construction, a single strip-like widening 9 with a width corresponding at least approximately to the width of the rail 2 at the rail base is formed substantially symmetrically under the rail 2 on the support plate 7. Here, the widening 9 has a somewhat trapezoidal cross section, corresponding to the approximately trapezoidal cross section of the recess 10 in the base plate 6. The width of the recess 10 and widening 9 must exceed a minimum in order to ensure adequate support and sufficient lateral stability of the rail support 5. Otherwise, the present cross-sectional design leads to an effective self-centering when the wheel of a rail vehicle rolls over, so that the transverse deflection of the head of the rail 2 is minimal under the action of horizontal forces (sinusoidal and centrifugal forces).

Fig. 2 läßt noch erkennen, daß die leistenartige Aufweitung 9 an der Tragplatte 7 als Hohlprofil ausgeführt ist, und zwar als am Boden 11 offenes Hohlprofil. Dies ist eine Konstruktion, die in besonders zweckmäßiger Weise dann verwirklicht werden kann, wenn die Tragplatte 7 insgesamt als Stahl-Stranggußprofil oder Stahl-Walzprofil ausgeführt ist.Fig. 2 shows that the strip-like expansion 9 on the support plate 7 is designed as a hollow profile, namely as an open hollow profile at the bottom 11. This is a construction which can be implemented in a particularly expedient manner if the supporting plate 7 is designed as a continuous steel casting profile or a rolled steel profile.

Eine Alternativlösung für den Schienenunterbau 3 zeigt Fig. 4. Hier ist an der Grundplatte 6 jeder Schienenunterlage 5 im wesentlichen symmetrisch unter jeder der Schienen 2 je eine einzige, leistenartige Aufweitung 9 mit einer mindestens etwa der Breite der Schiene 2 am Schienenfuß entsprechenden Breite ausgebildet und im Querschnitt etwa trapezförmig ausgeführt. In entsprechender Weise ist dann die Ausnehmung 10 an der Tragplatte 7 ausgebildet. Im speziellen Fall gilt hier, daß die wannenartige Ausnehmung 10 durch den von einem von der Tragplatte 7 nach unten abragenden Doppelsteg begrenzten Freiraum gebildet ist. Die Tragplatte 7 ist also insgesamt im Querschnitt etwa T-förmig ausgeführt, wobei der T-Steg der Tragplatte 7 als Doppelsteg ausgeführt ist. Gemeinsam mit dem Quersteg der Tragplatte 7 bildet der Doppelsteg einen Freiraum mit trapezförmigem Querschnitt, das ist wiederum in besonders zweckmäßiger Weise zu der Ausführung der Tragplatte 7 als Stahl-Stranggußprofil oder Stahl-Walzprofil korreliert.An alternative solution for the rail substructure 3 is shown in FIG. 4. Here, on the base plate 6 of each rail underlay 5, there is essentially a single, strip-like widening 9 with an at least approximately the width of the rail 2 at the rail base, corresponding to each of the rails 2 Width formed and executed in trapezoidal cross section. In a corresponding manner, the recess 10 is then formed on the support plate 7. In a special case, the trough-like recess 10 is formed by the free space delimited by a double web projecting downwards from the support plate 7. The support plate 7 is thus approximately T-shaped in cross section, the T-web of the support plate 7 being designed as a double web. Together with the transverse web of the support plate 7, the double web forms a free space with a trapezoidal cross section, which in turn is correlated in a particularly expedient manner to the design of the support plate 7 as a continuous steel profile or a rolled steel profile.

In den beiden zuvor erläuterten Ausführungsbeispielen beträgt der Trapez-Basiswinkel etwa 70°, was sich in Versuchen hinsichtlich der Krafteinleitungsverhältnisse als besonders zweckmäßig erwiesen hat.In the two previously described exemplary embodiments, the trapezoidal base angle is approximately 70 °, which has proven to be particularly expedient in tests with regard to the force application conditions.

Bei der Herstellung des erfindungsgemäßen Schienenunterbaus 3 ist es unter Umständen nicht möglich, die Grundplatten 6 der Schienenunterlagen 5 einer Schiene 2 mit ausreichender Präzision mit den Ausnehmungen 10 bzw. den Aufweitungen 9 zu versehen. Das gilt insbesondere bei aus Beton od. dgl. bestehenden Grundplatten 6. In diesem Fall hat es sich als besonders zweckmäßig erwiesen, daß in die wannenartige Ausnehmung 10 bzw. auf die leistenartige Aufweitung 9 der Grundplatte 6 eine Profileinlage 12, vorzugsweise eine als Stahl-Stranggußprofil oder Stahl-Walzprofil ausgeführte, insbesondere kontinuierlich durchlaufende Profileinlage 12 eingesetzt bzw. aufgesetzt ist. Dies ist in den Fig. 2, 3 und 4 gezeigt. In den Fig. 3 und 4 ist die Profileinlage zweiteilig ausgeführt und nur an den Flanken der Ausnehmung 10 bzw. der Aufweitung 9 angeordnet. Die Rohkontur der Ausnehmung 10 bzw. Aufweitung 9 muß in diesem Fall schon relativ genau, beispielsweise durch ein Präzisionsschalungsprofil, vorgegeben sein. Ist die Rohkontur nicht sehr exakt vorgegeben, so empfiehlt sich die in Fig. 2 dargestellte Ausführungsform mit einem Mörtelbett 13, in das die Profileinlage 12 eingelegt bzw. eingebettet ist. Anstelle eines Mörtelbetts 13 kann auch eine entsprechende Klebstoffeinbettung od. dgl. vorgesehen sein.In the manufacture of the rail substructure 3 according to the invention, it may not be possible to provide the base plates 6 of the rail supports 5 of a rail 2 with the recesses 10 or the widenings 9 with sufficient precision. This applies in particular to base plates 6 made of concrete or the like. In this case it has proven particularly expedient that a profile insert 12, preferably a steel insert, is inserted into the trough-like recess 10 or the strip-like widening 9 of the base plate 6. Continuous casting or rolled steel profile, in particular continuously running profile insert 12 is used or placed. This is shown in Figs. 2, 3 and 4. 3 and 4, the profile insert is made in two parts and is only arranged on the flanks of the recess 10 or the widening 9. In this case, the raw contour of the recess 10 or widening 9 must already be predefined relatively precisely, for example by a precision formwork profile. If the raw contour is not specified very precisely, the embodiment shown in FIG. 2 with a mortar bed 13 in which the profile insert 12 is inserted or embedded is recommended. Instead of one A corresponding adhesive embedding or the like can also be provided in the mortar bed 13.

Die erfindungsgemäße Konstruktion bietet die Möglichkeit, eine kontinuierliche Schienenlagerung gewissermaßen als ein einheitlich handhabbares Lagerteil anzubieten. Dazu zeigt die in den Fig. 2, 3 und 4 verwirklichte Ausgestaltung, daß die Tragplatte 7, die Dämpfungselemente 8 und ggf. die Profileinlage 12 fest verbunden, als Einheit handhabbar und als Einheit in die wannenartige Ausnehmung 10 einsetzbar oder auf die leistenartige Aufweitung 9 aufsetzbar sind.The construction according to the invention offers the possibility of offering a continuous rail bearing as a single, manageable bearing part. 2, 3 and 4 shows that the support plate 7, the damping elements 8 and possibly the profile insert 12 are firmly connected, can be handled as a unit and used as a unit in the trough-like recess 10 or on the strip-like widening 9 are attachable.

Schienen der hier erläuterten Art sind nicht nur quer zur Längsrichtung gerichteten Horizontalkräften ausgesetzt, sondern auch in Längsrichtung gerichteten Horizontalkräften, beispielsweise beim Abbremsen eines Schienenfahrzeugs. Hierzu zeigt eine weitere Ausgestaltung, die jedoch in den Figuren nicht dargestellt ist, daß in Längsrichtung der Schiene in größeren Abständen voneinander an den Schienenunterlagen quer zur Längsrichtung verlaufend angeordnete Aufweitungen und Ausnehmungen vorgesehen und, vorzugsweise, jeweils am Rand einer Schienenunterlage angeordnet sind. Ebenfalls in der Zeichnung nicht zu erkennen ist, daß die Dämpfungselemente als langgestreckte Strangpreßprofile, vorzugsweise von in unbelastetem Zustand im wesentlichen rechteckigem Querschnitt, ausgeführt sein können.Rails of the type explained here are not only exposed to horizontal forces directed transversely to the longitudinal direction, but also to horizontal forces directed in the longitudinal direction, for example when braking a rail vehicle. For this purpose, a further embodiment, which is not shown in the figures, shows that in the longitudinal direction of the rail, widenings and recesses arranged transversely to the longitudinal direction are provided on the rail supports at greater distances from one another and, preferably, are each arranged on the edge of a rail support. Likewise, it cannot be seen in the drawing that the damping elements can be designed as elongated extruded profiles, preferably of essentially rectangular cross section in the unloaded state.

Die Zeichnung zeigt durchweg nur Ausführungsbeispiele in Verbindung mit einer Breitfußschiene, entsprechende Konstruktionen sind aber auch mit einer Rillenschiene in versenkter Bauweise möglich, wobei dann der dargestellte Schienenunterbau noch eine Pflasterauflage od. dgl. erhält.The drawing shows only exemplary embodiments in connection with a wide base rail, but corresponding constructions are also possible with a grooved rail in a recessed construction, in which case the rail substructure shown is also given a plaster covering or the like.
