Abstract

Elastic plates for level railroad crossings have rail-adjacent edges which are profiled in their vertical cross sections to provide the required interlock. The plates have a first pair of grooves in the top and the bottom of the plate running parallel to the rail and have a second pair of upper and lower parallel grooves in the top and the bottom of the plate running transverse to the rail. In each pair of grooves, the groove in the top of the plate is laterally offset with respect to a parallel groove in the bottom of the plate, and each pair of grooves forms an expansion and contraction crease therebetween. Pairs of grooves in the top and the bottom of the plate are spaced, so that the distances between individual expansion creases, or between expansion creases formed by groups of creases, are large relative to the distance between the grooves which constitute the expansion creases. The first and second pairs of grooves intersect one another and in order to prevent an aperture or opening from being formed in the plate at the points of intersection, an integral layer of material is provided at each intersection to seal between the upper and lower sides of the plates.

Description

Die Erfindung betrifft eine elastische Platte für schienengleiche Bahnübergänge und gegebenenfalls außer­halb der Schienen angeordnete Fahrbahnbeläge, die sich von Schiene zu Schiene, bzw. von Schiene zum Fahrbahn­anschluß erstreckt und deren schienenseitige Ränder für die erforderlichen Verbundwirkungen in senkrechter Richtung im Querschnitt profilförmig gestaltet sind.The invention relates to an elastic plate for level crossings and possibly arranged outside the rails roadway coverings, which extends from rail to rail, or from rail to the carriageway connection and whose rail-side edges are designed in profile in cross section for the required composite effects in the vertical direction.

Solche elastischen Platten werden in verschiedenster Ausführung für die Schaffung von schienengleichen Bahn­ übergängen verwendet, da sie den Vorteil haben, aufgrund der Resistenz des Materials gegen witterungs- und industrielle Einwirkungen eine lange Lebensdauer aufzu­weisen und wartungsfreundlich sind. Infolge der elastischen Verformbarkeit des Plattenmaterials lassen sich die Platten auf ihrer Unterlage so verlegen, daß keine Verspannungen des Plattenmaterials zurückbleiben.Such elastic plates are available in a wide variety of designs for the creation of rail-like tracks transitions are used because they have the advantage of being long-lasting and easy to maintain due to the material's resistance to weather and industrial influences. As a result of the elastic deformability of the plate material, the plates can be laid on their base so that no tension of the plate material remains.

Für Bahnübergänge, welche von Schwertransportern befahren werden, ist man genötigt, relativ dicke und schwere Platten für die Herstellung eines schienengleichen Bahnüberganges zu verwenden. Dagegen ist man bestrebt, für wenig befahrene Bahnübergänge oder reine Fußgängerübergänge Platten geringerer Stärke aus relativ hartem, elastischem Material zu verwenden. Diese sind aufgrund der Materialersparnis kostengünstiger und außerdem kann deren Anlieferung sowie deren Ein- und Ausbau noch problemloser erfolgen als dies bei den bisher üblichen dicken und schweren Platten der Fall war.For level crossings, which are used by heavy transporters, it is necessary to use relatively thick and heavy plates for the production of a level crossing with rails. In contrast, efforts are being made to use slabs of lesser thickness made of relatively hard, elastic material for level crossings with little traffic or pure pedestrian crossings. These are more cost-effective due to the material savings and, in addition, their delivery, installation and removal can be carried out even more easily than was the case with the thick and heavy panels that were customary to date.

Es hat sich jedoch gezeigt, daß bei Platten geringerer Gesamtdicke vor allem dafür gesorgt werden muß, daß diese bei allen Temperatur- Witterungs- und Belastungsbean­spruchungen ebenflächig auf ihrem Unterbau liegen bleiben und sich nicht verwölben oder bei Beanspruchung aus ihrem gegenseitigen Verbund herausspringen.However, it has been shown that, in the case of sheets of reduced overall thickness, it is particularly important to ensure that they remain flat on their substructure in all temperature, weather and stress conditions and do not warp or when stressed from them jump out of mutual bond.

Der Erfindung liegt daher die Aufgabe zugrunde, die Platten so auszubilden, daß sie den vorstehend genannten Forderungen genügen.The invention is therefore based on the object to design the plates so that they meet the above requirements.

Diese Aufgabe wird dadurch gelöst, daß auf der oberen und auf der unteren Oberfläche der Platte parallel zum Schienen­verlauf und gegebenenfalls quer hierzu verlaufende Rillen vorgesehen sind, daß die zueinander parallelen Rillen der oberen Plattenflächen zu den parallelen Rillen der unteren Plattenflächen seitlich versetzt angeordnet sind und daß jeweils zwei oder mehrere benachbarte der zueinander parallelen und seitlich zueinander versetzt sich gegenüber­liegenden Rillen der oberen und unteren Plattenflächen eine bzw. mehrere elastische Dehnungsfalten bilden, wobei die Rillen so auf der oberen und der unteren Plattenfläche angeordnet sind, daß die Abstände einzelner Dehnungsfalten bzw. der aus mehreren Dehnungsfalten gebildeten Falten­gruppen voneinander groß sind gegenüber den Abständen zwischen den die Dehnungsfalten bildenden Rillen.This object is achieved in that on the upper and on the lower surface of the plate parallel to the track and possibly transverse grooves are provided, that the mutually parallel grooves of the upper plate surfaces are laterally offset from the parallel grooves of the lower plate surfaces and that In each case two or more adjacent grooves of the upper and lower plate surfaces which are parallel to one another and laterally offset from one another form one or more elastic expansion folds, the grooves being arranged on the upper and lower plate surfaces in such a way that the distances between individual expansion folds or the fold groups formed from a plurality of expansion folds are large compared to the distances between the grooves forming the expansion folds.

Durch die Schaffung von ein oder mehreren Dehnungsfalten, die in Plattenlängsrichtung, also parallel zum Schienen­verlauf und gleichzeitig auch quer hierzu vorgesehen sein können, hat man eine Möglichkeit geschaffen, daß auch bei Verwendung eines relativ starren und harten elastischen Materials die Platten Bereiche aufweisen, die eine elastische Verformung zulassen. Die gemäß der Erfindung geschaffenen Dehnungsfalten wirken wie Falten eines Balgs und bewirken, daß sich die Breite einer mittels ihrer Randprofile unter den Schienenköpfen eingeklemmten bzw. am Fahrbahnrand ver­ankerten Platte, abhängig von der Temperatur oder von auf die Plattenoberfläche einwirkender Belastungen, gering­fügig, aber in ausreichendem Maße verändern kann, ohne daß die Platte als Ganzes auf ihrem Unterbau verrutscht oder sich verwölbt. Entsprechendes gilt auch für Plattenaus­dehnung in Schienenlängsrichtung.By creating one or more expansion folds which are provided in the longitudinal direction of the plate, that is to say parallel to the course of the rail and at the same time also transversely thereto can, one has created a possibility that even when using a relatively rigid and hard elastic material, the plates have areas that allow elastic deformation. The expansion folds created according to the invention act like folds of a bellows and have the effect that the width of a plate clamped under the rail heads by means of its edge profiles or anchored to the edge of the track, depending on the temperature or on loads acting on the plate surface, is slight, but sufficient Dimensions can change without the plate as a whole slipping on its base or buckling. The same also applies to plate expansion in the longitudinal direction of the rails.

Vorzugsweise sind die aneinandergrenzenden Ränder der einander benachbarten Platten im Querschnitt ebenfalls profilförmig ausgebildet und zwar vorzugsweise in Form von Nut und Feder. Mit Hilfe der Nut-Feder-Verbindung greifen die benachbarten Platten lückenlos ineinander. Um jedoch ein Auseinanderrutschen infolge von stärkeren Bean­spruchungen der Platten zu vermeiden, sind im Randbereich der aneinandergrenzenden Plattenränder von der oberen Plattenoberfläche ausgehende schräg zum jeweiligen Platten­rand hin verlaufende Einschnitte vorgesehen, die zur Auf­nahme der Schenkel einer etwa U-förmig ausgebildeten Klammer, die die beiden aneinandergrenzenden Platten überbrückt, dienen.The adjoining edges of the plates adjacent to one another are preferably also profile-shaped in cross section, preferably in the form of tongue and groove. With the help of the tongue and groove connection, the neighboring panels interlock seamlessly. However, in order to avoid slipping apart as a result of greater stresses on the plates, incisions are made in the edge region of the adjoining plate edges, starting from the upper plate surface and extending obliquely to the respective plate edge, to accommodate the legs of an approximately U-shaped clamp, bridging the two adjacent plates serve.

Es ist somit sichergestellt, daß ein Arbeiten des Materials aufgrund von Witterung, Temperatur- und Krafteinwirkung mit Hilfe der Dehnungsfalten ausgeglichen werden kann ohne daß infolge von kurzfristigen stoßartigen Einwirkungen ein Auseinandergleiten der Platten befürchtet werden müßte.It is thus ensured that working of the material due to weather, temperature and force can be compensated for with the help of the expansion folds, without fear of the plates sliding apart as a result of short-term, sudden effects.

Um eine elastische Dehnungsfähigkeit der gebildeten Dehnungsfalten zu erzielen, sind die Einschnittiefen der Rillen so gewählt, daß die Summe der Einschnittiefen der parallel sich versetzt gegenüberliegenden Rillen ≧ der Ge­samtdicke der Platte ist.In order to achieve an elastic extensibility of the expansion folds formed, the incision depths of the grooves are chosen so that the sum of the incision depths of the parallel opposing grooves ≧ is the total thickness of the plate.

Zur Vermeidung einer Elastizitätsverringerung der Dehnungs­falten infolge Verschmutzung der Rillen wählt man bevorzugt die Einschnittstiefe der auf der oberen Plattenfläche vorgesehenen Rille ≦ der Einschnittiefe der auf der unteren Plattenfläche angeordneten Rillen. Außerdem ist die Wahl eines V-förmigen Querschnitts der Rille für die Ver­meidung von Verklemmungen infolge von in die Rillen ein­gedrungener Steine oder dergleichen zweckmäßig. Selbst­verständlich können aber auch andere Einschnittsformen gewählt werden.In order to avoid a reduction in the elasticity of the expansion folds as a result of soiling of the grooves, the cut depth of the groove provided on the upper plate surface bevorzugt the cut depth of the grooves arranged on the lower plate surface is preferably selected. In addition, the choice of a V-shaped cross section of the groove is expedient in order to avoid jamming as a result of stones or the like which have penetrated into the grooves. Of course, other incision shapes can also be selected.

Da Dehnungsfalten sowohl in Plattenlängs- als auch in Plattenquerrichtung vorgesehen sein können, würden sich an den Kreuzungsstellen der Rillen durch die Platten hin­durchverlaufende Öffnungen ergeben, die aus der Platte eine Loch- oder Gitterplatte machen würden. Um dies zu vermeiden, werden die Öffnungen durch eine geeignete Form­gebung des Formwerkzeuges mit einer mit dem Plattenmaterial einstückigen Materialschicht bei der Plattenherstellung verschlossen.Since expansion folds can be provided in both the longitudinal and transverse direction of the plate, openings would result at the crossing points of the grooves through the plates and would make the plate a perforated or grid plate. In order to avoid this, the openings are closed by a suitable shaping of the molding tool with a material layer integral with the plate material during plate production.

Eine Platte 1 aus einem relativ harten, jedoch noch aus­reichend elastischem Gummimaterial einer Gesamtplatten­stärke von etwa 60 bis 70 mm, dient zur Schaffung eines schienengleichen Bahnüberganges zwischen einer Schiene 2 und dem Fahrbahnrand 3. Die in Schienenrichtung verlaufenden Ränder der Platte 1 sind dem Schienenkopf 4 einerseits und der Fahrbahnbefestigung 5 andererseits durch eine entsprechen­de Profilausbildung angepaßt. Die Schiene 2 ist in herkömm­licher Weise auf den Schwellen 6 befestigt. Die Schwellen­befestigungsvorrichtung 7 ist durch ein Schienenformstück 8 abgedeckt. Zwischen der Fahrbahnbefestigung 5 und der Schiene 2 liegen sich über mehrere Schwellen 6 erstreckende Holzbohlen 9, auf denen die Platte 1 ruht. Ein von der unteren Platten­fläche aus nach unten ragender Vorsprung 10 liegt seitlich an dem Schienenformstück 8 an und dient der seitlichen Arre­ tierung der Platte 1.A plate 1 made of a relatively hard, but still sufficiently elastic rubber material with a total plate thickness of approximately 60 to 70 mm serves to create a level crossing between a rail 2 and the road edge 3. The edges of the plate 1 running in the direction of the rail are the rail head 4 on the one hand and the roadway mounting 5 on the other hand adapted by a corresponding profile training. The rail 2 is attached to the sleepers 6 in a conventional manner. The threshold fastening device 7 is covered by a rail molding 8. Between the pavement attachment 5 and the rail 2 are wooden planks 9 extending over several sleepers 6, on which the plate 1 rests. A projection 10 projecting downward from the lower plate surface lies laterally on the rail molding 8 and serves for the lateral locking plate 1.

Die parallel zur Plattenoberfläche verlaufenden Vorsprünge der Plattenstirnfläche 1a sind die Federprofile 11, die in die nicht dargestellten Nuten einer angrenzenden Platte eingreifen.The projections of the plate end face 1 a running parallel to the plate surface are the spring profiles 11 which engage in the grooves, not shown, of an adjacent plate.

Eine im Schnittbild nach Fig. 1 erkennbare rechteckige Kerbe 12 in der Oberfläche der Platte 1 dient zur Aufnahme einer Klammer 13, die nach Fig. 5 aneinandergrenzende Platten zusammenhält und den festen Verbund der Platten ge­währleistet. Die Klammer 13 weist ein U-Profil auf. Ihre Schenkel 13 a, b verlaufen leicht schräg zu ihrem Verbindungs­stück 13 c und nähern sich zu ihren freien Enden hin, zum Zwecke eines sicheren Haltes in der Platte 1.
Das Verbindungsstück 13 c ist in die Kerbe 12 eingelassen und versenkt angeordnet.A recognizable in the sectional view of FIG. 1 rectangular notch 12 in the surface of the plate 1 serves to receive a bracket 13 which holds together adjacent plates according to FIG. 5 and ensures the firm bond of the plates. The bracket 13 has a U-profile. Their legs 13 a, b run slightly obliquely to their connecting piece 13 c and approach their free ends for the purpose of a secure hold in the plate 1.
The connector 13 c is embedded in the notch 12 and arranged sunk.

In der Platte 1 ist eine Dehnfuge 14 in Schienenlängs­richtung und zwei Dehnfugen 15 in Querrichtung hierzu vor­gesehen. Jede Dehnfuge 14 bzw. 15 ist durch das Zusammen­wirken von zwei Rillen 16 und 17 gebildet. Die Rille 16 ver­läuft auf der unteren Fläche der Platte 1 in Form eines V-förmigen Einschnittes in Schienenlängsrichtung. Die maximale Einschnittiefe beträgt bei einer Gesamtdicke der Platte 1 von ca. 60 bis 70 mm etwa 40 mm.An expansion joint 14 in the longitudinal direction of the rail and two expansion joints 15 in the transverse direction are provided in the plate 1. Each expansion joint 14 and 15 is formed by the interaction of two grooves 16 and 17. The groove 16 runs on the lower surface of the plate 1 in the form of a V-shaped incision in the longitudinal direction of the rail. The maximum incision depth for a total thickness is Plate 1 from about 60 to 70 mm about 40 mm.

Die Rille 17 verläuft auf der oberen Fläche der Platte 1 ebenfalls in Form eines V-förmigen Einschnittes in Schienen­längsrichtung. Sie ist aber gegenüber der Rille 16 seitlich um 3,5 cm (Abstand der Einschnittsymmetrie-Mittellinien) versetzt. Ihre maximale Einschnittstiefe beträgt ca. 30 mm. Die seitliche Versetzung der Rillen 16 und 17 ist im Bei­spiel so gewählt, daß die in einem Bereich von etwa 10 mm zueinander parallel verlaufenden benachbarten Flanken 16 a und 17 a der V-förmigen Rillen 16 und 17 einen Steg 18 definieren, dessen Dicke etwa im Bereich von 15 bis 25 mm liegt. Im Beispiel beträgt die Stärke des Steges 20 mm. Bei dem hier verwendeten Gummimaterial betrug die Härte ca. 90 Shore. Die vorstehenden Angaben betreffend die Ab­messungen der Dehnfugen können hierfür als optimal angesehen werden. Natürlich hängt die Dimensionierung des Stegs 18 von den elastischen Eigenschaften des jeweils für die Platte verwendeten Gummimaterials ab.The groove 17 extends on the upper surface of the plate 1 also in the form of a V-shaped incision in the longitudinal direction of the rail. However, it is laterally offset from the groove 16 by 3.5 cm (distance of the incision symmetry center lines). Their maximum incision depth is approx. 30 mm. The lateral offset of the grooves 16 and 17 is chosen in the example so that the adjacent flanks 16 a and 17 a of the V-shaped grooves 16 and 17, which run parallel to one another in a region of approximately 10 mm, define a web 18, the thickness of which is approximately in Range is from 15 to 25 mm. In the example, the thickness of the web is 20 mm. The hardness of the rubber material used here was approx. 90 Shore. The above information regarding the dimensions of the expansion joints can be regarded as optimal for this. Of course, the dimensioning of the web 18 depends on the elastic properties of the rubber material used for the plate.

Mit Hilfe der Dehnfuge 14 können elastische Verformungen der Platte 1 zwischen dem Schienenformstück 8 und der Fahrbahnbefestigung 5 aufgefangen werden. Entsprechendes gilt für die Dehnfugen 15, die quer zur Schienenrichtung verlaufen.With the help of the expansion joint 14, elastic deformations of the plate 1 can be absorbed between the rail molding 8 and the roadway fastening 5. The same applies to the expansion joints 15, which run transversely to the rail direction.

In Fig. 3 und 4 ist eine Platte 20 gezeigt, die zwischen zwei Schienensträngen eingelegt wird. Die schienen­seitigen Ränder der Platte 20 liegen an den Schienenköpfen an. Ihr im Bereich des Schienenkopfes befindliches Profil 21 bzw. 22 weist eine Spurrille 23 auf. Im übrigen gilt hier für den Unterbau der Platte 20 das gleiche wie bereits im Zusammenhang mit den Fig. 1 und 2 ausgeführt wurde.
Vorsprünge 24 und 25 auf der unteren Fläche der Platte 20 dienen zur Anlage an den Schienenformstücken 26 und ragen in Zwischenräume 27 zwischen den Schienenformstücken 26 und den den Unterbau bildenden Holzblöcken 28, die sich über mehrere Schienenschwellen erstrecken. Im übrigen sind übereinstimmende Konstruktionsmerkmale mit den gleichen Bezugsziffern gekennzeichnet wie in den Fig. 1 und 2, so daß eine Zuordnung ohne weitere Erläuterung möglich ist.3 and 4, a plate 20 is shown, which is inserted between two rail tracks. The rail-side edges of the plate 20 abut the rail heads. Your profile 21 or 22 located in the area of the rail head has a track groove 23. For the rest, the same applies to the substructure of the plate 20 as has already been explained in connection with FIGS. 1 and 2.
Projections 24 and 25 on the lower surface of the plate 20 serve to abut the rail fittings 26 and protrude into spaces 27 between the rail fittings 26 and the wooden blocks 28 forming the substructure, which extend over a plurality of rail sleepers. Otherwise, identical design features are identified by the same reference numerals as in FIGS. 1 and 2, so that an assignment is possible without further explanation.

In Fig. 6 ist in abgebrochener Darstellung ein Schnittbild längs der Linie A....A der Fig. 4 gezeigt, welches die Aus­bildung der Kreuzung 29 einer Dehnfuge 14 mit einer Dehnfuge 15 erkennen läßt und insbesondere zeigt, daß das sich zwangs­läufig ergebende Loch mit einer Materialschicht 30 ver­schlossen ist. Diese Materialschicht wird durch entsprechende Formgebung der Gießform an den Kreuzungsstellen 29 der Dehn­fugen 14, 15 integriert mit dem übrigen Plattenmaterial ge­schaffen.In Fig. 6, a sectional view along the line A .... A of Fig. 4 is shown in broken view, which shows the formation of the intersection 29 of an expansion joint 14 with an expansion joint 15 and in particular shows that the inevitably resulting hole is closed with a material layer 30. This material layer is created by appropriate shaping of the casting mold at the intersections 29 of the expansion joints 14, 15 integrated with the rest of the plate material.
