The plates (3) fitted between the rails are shaped like a U-profile extending at right angles to the longitudinal rail direction. The profiled plate has a mainly flat cover wall (9) with downward facing flanged ribs projecting from the wall edges. Support lugs (5) on the cover plates engaging into at least one of the rails are formed by the rib ends only.

Description

Die Erfindung bezieht sich auf eine Gleiseindeckung, welche aus zwischen die beiden Schienen eines Gleises eingefügten Eindeckungsplatten und gegebenenfalls auch aus außen an diese Schienen anschließend verlegten Eindeckungsplatten gebildet ist, welche Eindeckungsplatten aus einem Verbundwerkstoff bestehen und zumindest an einem einer Schiene zugewandten Rand mit Stütznasen versehen sind, welche unter Einfügung elastischer Beilagen in die seitliche Ausnehmung der betreffenden Schiene eingreifen, wobei der Verbundwerkstoff aus mehreren miteinander vermengten Komponenten gebildet ist.The invention relates to a track covering, which from covering plates inserted between the two rails of a track and possibly also from the outside Rails is then formed covering sheets, which covering panels are made of a composite material and at least on an edge facing a rail with support lugs are provided, which with the insertion of elastic inserts in the engage lateral recess of the rail in question, wherein the composite material consisting of several components mixed together is formed.

Gleiseindeckungen vorgenannter Art sind in verschiedenen Ausführungsformen bekannt und dienen meist zur Bildung von auf Schienenniveau liegenden Straßenkreuzungen oder ähnlichen auf Schienenniveau liegenden Verkehrsflächen im Bereich von Fabrikations- oder Lagereinrichtungen oder auch der Dämpfung des beim Befahren von Gleisanlagen entstehenden Lärms, wobei gelegentlich auch eine Begehbarkeit solcher schalldämmender Gleiseindeckungen in Betracht gezogen wird. Bei den bekannten Gleiseindeckungen vorgenannter Art ist die Herstellung der zum Eindecken benötigten Platten und auch deren Verlegung am Gleis meist mit einem unerwünscht großen Aufwand verbunden, wobei sich oft Schwierigkeiten daraus ergeben, dass, bedingt durch das Gewicht der Platten und durch spezielle Manipulationsschritte, welche beim Einbau und beim Ausbau der Platten vorgenommen werden müssen, spezielle Hebezeuge und andere Vorrichtungen einzusetzen sind, was bei beengten Platzverhältnissen, wie sie z.B. in Tunnels herrschen, zu beträchtlichen Schwierigkeiten führen kann.Track coverings of the aforementioned type are in different Embodiments are known and are mostly used to form on Road level intersections or similar on Traffic areas in the area of manufacturing or storage facilities or the damping of the Driving on track systems arising noise, occasionally also a walkability of such sound-absorbing track coverings is being considered. With the known track coverings the aforementioned type is the production of those required for mounting Boards and their laying on the track mostly with an undesirable great effort, which often leads to difficulties result from the fact that, due to the weight of the plates and through special manipulation steps, which during installation and when lifting the panels must be made special lifting equipment and other devices are to be used, what in confined spaces Available space, e.g. rule in tunnels, too can cause considerable difficulties.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Gleiseindeckung eingangs genannter Art zu schaffen, bei der die Eindeckungsplatten einfach gebaut und einfach mit geringem Aufwand herstellbar sind, wobei ein geringes Gewicht der Platten erzielbar sein soll und so der Ein- und der Ausbau dieser Platten mit einfachen Hebezeugen und im Bedarfsfall auch ohne Hebezeuge von Hand vorgenommen werden kann.It is an object of the present invention to provide a track covering to create the type mentioned, in which the covering plates simply built and simple with little effort can be produced, and a low weight of the plates can be achieved should be and so the installation and removal of these panels simple hoists and, if necessary, also without hoists from Hand can be made.

Die erfindungsgemäße Gleiseindeckung eingangs erwähnter Art ist dadurch gekennzeichnet, dass mindestens die zwischen die beiden Schienen des Gleises eingefügten Eindeckungsplatten die Form eines quer zur Schienenlängsrichtung verlaufenden U-Profils aufweisen, das aus einer im Wesentlichen ebenen Deckwand und an deren quer zur Schienenlängsrichtung verlaufenden Querrändern angeordneten, von der Deckwand nach unten abstehenden Flanschrippen gebildet ist, wobei die in mindestens eine der Schienen eingreifenden Stütznasen nur durch die Flanschrippenenden gebildet sind, welche an jenen Längsrand der Deckwand, der in Längsrichtung der betreffenden Schiene verläuft, angrenzen. Durch diese Ausbildung kann der vorstehend erwähnten Zielsetzung gut entsprochen werden. Die die Gleiseindeckung bildenden Platten können durch ihre einfache Form mit verhältnismäßig geringem Aufwand hergestellt werden, wobei eine gute Tragfähigkeit dieser Platten schon bei verhältnismäßig geringem Gewicht erzielt werden kann. Es kann eine gute, für intensives Begehen ausreichende Belastbarkeit bei einem Plattengewicht von weniger als 50 kg erhalten werden. Dementsprechend sind solche Eindeckungsplatten im Bedarfsfall, ohne größere Hebeeinrichtungen oder dergl. zu benötigen, von Hand ein- und ausbaubar. Die Stütznasen der Eindeckungsplatten, welche in die neben dem Schienensteg befindliche seitliche Ausnehmung der betreffenden Schiene eingreifen, wobei üblicherweise ein elastisches Profil zwischen die Stütznasen und die betreffende Schiene eingefügt wird, sind in Schienenlängsrichtung gesehen verhältnismäßig schmal, und es wird dadurch die beim Einbau und beim Ausbau der die Gleiseindeckung bildenden Eindeckungsplatten erforderliche Manipulation erleichtert. Außerdem ergeben sich aus der vorgesehenen Form der die Gleiseindeckung bildenden Eindeckungsplatten verhältnismäßig leicht überschaubare statische Verhältnisse, und es kann dadurch auf einfachem Wege eine optimierte Dimensionierung erzielt werden. Hinsichtlich des Verbundwerkstoffes, aus dem die Eindeckungsplatten gebildet sind, steht eine breite Skala von Möglichkeiten zur Verfügung. Für mindestens eine Komponente kommen natürliche Mineralstoffe in gebrochenem oder gemahlenem Zustand ebenso in Betracht wie feinteilige, poröse Leichtbauwerkstoffe, wie beispielsweise Kunststoffgranulat, körnige oder kugelförmige und gebrannte Tonerdeteilchen, körnige Schlackenteilchen und ähnliche Partikel, aus natürlichen oder künstlich hergestellten Basismaterialien, wobei auch Gemische aus verschiedenartigen Partikeln, wie sie vorstehend erwähnt sind, zum Einsatz kommen können. Als bindende Komponente kommen insbesondere Zement und auch Kunststoffbindemittel in Frage, wobei auch diesbezüglich die Möglichkeit Bindemittelgemische einzusetzen besteht. Es ist in den meisten Fällen günstig, wenn der Verbundwerkstoff, aus dem die Eindeckungsplatten gebildet sind, eine Bewehrung beinhaltet, die z.B. aus Stahl oder anderen Metallen, aus Kunststofffäden, Glasfasersträngen, oder Fasermaterialien bestehen kann, wobei bei den Fasermaterialien sowohl natürliche als auch synthetische in Betracht zu ziehen sind und sowohl Beimengungen von Kurzfasern zum Komponentengemenge als auch Einbettungen von längeren aus Fasermaterial gebildeten Strängen in Frage kommen. Die Bewehrung kann auch die Form vorgefertigter flächenhafter Körper haben, wie z.B. die Form von Gittern, Netzen oder Vliesen. Wird eine möglichst hohe Schalldämpfung angestrebt, ist es günstig, wenn eine Komponente des Verbundwerkstoffes ein wie vorerwähnt poröser Leichtbauwerkstoff ist oder zumindest vorwiegend aus einem solchen Werkstoff besteht. Weiter ist es dabei vorteilhaft, die nach oben gerichtete Fläche der Eindeckungsplatten schallschluckend strukturiert auszubilden, z.B. mit geeigneten Rippen oder Hohlausnehmungen zu versehen.The track covering according to the invention of the type mentioned at the beginning is characterized in that at least those between the Cover plates inserted into both rails of the track Form of a U-profile running transversely to the longitudinal direction of the rail have, which consists of a substantially flat top wall and their transverse edges running transversely to the longitudinal direction of the rail arranged flange ribs projecting downward from the top wall is formed, which in at least one of the rails engaging support lugs formed only by the flange ends are which on that longitudinal edge of the top wall, which in the longitudinal direction of the rail concerned, border. By this training can do the above mentioned purpose well be met. The slabs forming the track covering can by their simple shape with relatively little Effort can be made, with a good carrying capacity of this Plates can be achieved with a relatively low weight can. It can be a good resilience sufficient for intensive walking obtained with a plate weight of less than 50 kg become. Accordingly, such cover plates are in If necessary, without needing larger lifting devices or the like, can be installed and removed by hand. The support lugs of the roofing slabs, which in the next to the rail web engage lateral recess of the rail in question, wherein usually an elastic profile between the support lugs and The rail in question is inserted in the longitudinal direction of the rail seen relatively narrow, and it becomes the during the installation and removal of the track covering Covering plates required manipulation facilitated. Moreover result from the intended form of the track covering covering slabs relatively easily manageable static conditions and it can be due to this optimized dimensioning can be easily achieved. With regard to the composite material from which the roofing slabs educated, there is a wide range of possibilities to disposal. Natural come for at least one component Minerals in broken or ground condition also in Consider how finely divided, porous lightweight materials, such as Plastic granules, granular or spherical and baked alumina particles, granular slag particles and the like Particles, from natural or artificially produced base materials, where mixtures of different types of particles, as mentioned above can be used. As binding component come in particular cement and also plastic binders in question, but also the possibility Use of binder mixtures exists. It is in the Most favorable when the composite material from which the Roofing slabs are formed, which includes reinforcement e.g. from steel or other metals, from plastic threads, glass fiber strands, or fiber materials can exist, with the Fiber materials are considered both natural and synthetic to be drawn and both admixtures of short fibers for Component batch as well as embedding of longer ones made of fiber material formed strands come into question. The reinforcement can also have the shape of prefabricated planar bodies, e.g. the form of grids, nets or fleeces. Will be one if possible Aiming for high sound absorption, it is beneficial if one component of the composite material is a porous lightweight material as mentioned above is or at least predominantly from one Material exists. It is also advantageous that the top structured surface of the roofing panels structured to absorb sound to train, e.g. with suitable ribs or hollow recesses to provide.

Eine bevorzugte Ausführungsform der erfindungsgemäßen Gleiseindeckung ist dadurch gekennzeichnet, dass an mindestens einem Längsrand der Deckwand eine Lippe angeordnet ist, deren Dicke geringer ist als die Dicke der Deckwand und welche von der einen Flanschrippe zur anderen Flanschrippe reicht und unter der an der Innenseite der angrenzenden Schiene freigehaltenen Spurkranzrille verlaufend an einer in die benachbarte seitliche Ausnehmung der angrenzenden Schiene eingefügten elastischen Beilage anliegt. Es kann durch diese Maßnahme auf einfache Weise ein guter Abschluss des von den Eindeckungsplatten überdeckten Raumes gegen ein unerwünschtes Eindringen von Fremdmaterial erzielt werden, was auch aus Sicherheitsgründen bedeutsam erscheint, da brennbares Fremdmaterial, wie z.B. Staubanhäufungen, entzündungsgefährdet ist und im Bahnbereich mit mancherlei Zündquellen zu rechnen ist, wobei z.B. achtlos weggeworfene Zigaretten ebenso wie Funken- und Lichtbogenbildungen bei elektrischen Bahnen Entzündungen herbeiführen können. Die vorerwähnte Lippe gibt durch ihre im Vergleich mit der Deckwand geringere Dicke auf einfache Weise die Möglichkeit, zwischen der als gegeben anzusehenden Tiefe der Spurkranzrille und der gleichfalls als gegeben anzusehenden Maximalhöhe von Schienenbefestigungsbauteilen und dergl. eine dauerhafte Trennung und Abdichtung vorzusehen.A preferred embodiment of the invention Track coverage is characterized in that at least a lip of a longitudinal edge of the top wall is arranged, the Thickness is less than the thickness of the top wall and which of the one flange rib extends to the other flange rib and under the on the inside of the adjoining rail there is a free flange groove running in one in the adjacent lateral recess the elastic rail inserted into the adjacent rail is present. This measure can easily be a good one Completion of the room covered by the covering slabs against unwanted intrusion of foreign material , which also seems important for security reasons, there flammable foreign material, e.g. Dust accumulation, flammable is and in the railway sector with various ignition sources can be expected, e.g. Carelessly thrown away cigarettes as well such as the formation of sparks and arcs in electrical tract inflammation can bring about. The aforementioned lip gives through their smaller thickness compared to the top wall on simple Way the possibility to choose between the given Depth of the flanged groove and that which can also be regarded as given Maximum height of rail fastening components and the like provide permanent separation and sealing.

Es ist sowohl für die Manipulation beim Einbau der Gleiseindeckungsplatten als auch hinsichtlich des Ausgleichs von Toleranzen an den einzelnen Elementen eines einzudeckenden Gleises von Vorteil, wenn man vorsieht, dass die Lippe aus einem nachgiebig biegsamen Material besteht.It is both for manipulation when installing the track covering slabs as well as in terms of balancing tolerances on the individual elements of a track to be covered an advantage if you provide that the lip from a compliant flexible material.

Für die Verlegung zwischen den beiden Schienen eines Gleises kommen in der Regel Eindeckungsplatten in Frage, welche an ihren beiden Längsrändern mit Stütznasen versehen sind, wobei solcherart die Eindeckungsplatten an beiden Seiten durch Eingriff in die seitlichen Ausnehmungen der Schienen gehalten sind. In bestimmten Fällen, wie etwa beim Vorhandensein zusätzlicher Leitprofile an der Schieneninnenseite, kann es sachdienlich sein, Eindeckungsplatten, welche zwischen die beiden Schienen eines Gleises einzufügen sind, nur an einem Längsrand mit Stütznasen zum Eingriff in eine seitliche Schienenausnehmung zu versehen und dementsprechend nur an einem Längsrand an einer Schiene abzustützen und eine solche Eindeckungsplatte im Bereich ihres anderen Längsrahdes auf an deren Bauelementen des Gleises, wie z.B. auf einer die Schienen tragenden Basisplatte, abzustützen. Man kann auch eigene Fundamente für den ohne Stütznasen ausgebildeten Längsrand von Eindeckungsplatten vorsehen. Eindeckungsplatten, welche nur an einem Längsrand mit Stütznasen versehen sind, kommen dabei auch besonders zur Eindeckung des außen an die Schienen eines Gleises anschließenden Bereiches in Frage. Bei Eindeckungsplatten, welche nur an einem Längsrand mit Stütznasen versehen sind und wie vorerwähnt an anderen Bauteilen des Gleises, wie z.B. an Grundplatten, oder anderweitigen Fundamenten aufliegen sollen, ist es im Hinblick auf die in der Regel auf etwas höherem Niveau als derartige Abstützungsstellen befindlichen Schienen vorteilhaft, wenn die Flanschrippen der Eindeckungsplatten im Abstand von dem mit Stütznasen versehenen Längsrand zum anderen Längsrand hin eine größere Höhe aufweisen als an dem den Stütznasen benachbarten Längsrand. Es ist dabei weiter vorteilhaft, wenn man vorsieht, dass die Flanschrippen in dem eine größere Höhe aufweisenden Abschnitt an ihrer Unterseite elastische Abstützungen aufweisen, und ergänzend dazu auch, dass die elastischen Abstützungen höhenverstellbar sind.For laying between the two rails of a track cover slabs are usually considered, which on their both longitudinal edges are provided with support lugs, such the cover plates on both sides by engaging in the lateral recesses of the rails are held. In particular Cases, such as the presence of additional guide profiles the inside of the rail, it can be useful which to insert between the two rails of a track are only on one longitudinal edge with support lugs for engagement to be provided in a side rail recess and accordingly to be supported only on a longitudinal edge on a rail and such a covering plate in the area of its other longitudinal frame on other components of the track, e.g. on a the Support base plate supporting rails. You can also make your own Foundations for the longitudinal edge of without Provide cover plates. Cover plates, which only on a longitudinal edge with support lugs also come especially to cover the outside of the rails of a track subsequent area in question. For roofing slabs, which are provided with support lugs only on one longitudinal edge and as mentioned above on other components of the track, e.g. on base plates, or other foundations, it is in the Regarding that, as a rule, at a somewhat higher level than such Supporting rails are advantageous if the flange ribs of the roofing slabs at a distance from the Supporting lugs provided a longitudinal edge towards the other longitudinal edge have a greater height than that adjacent to the support lugs Longitudinal edge. It is also advantageous if you provide that the flange ribs in the higher height section have elastic supports on their underside, and, in addition, that the elastic supports are height adjustable are.
