Abstract

A concrete sliding rail (2) consists of concrete that is abrasion-proof, high-strength or ultra-high-strength and covers the whole upper side of a travel-way plate (3). It also has no vertical joints and covers only that part of the upper side of the travel-way plate, on which the runners of a magnetic levitation railway come to rest in an emergency. Independent claims are also included for the following: (1) A travel way plate for a magnetic levitation railway; (2) A method for producing a travel way plate.

Description

Technisches GebietTechnical area

Die Erfindung betrifft die Konstruktion einer Gleitleiste für die Fahrplatte einer Magnetschwebebahn.The invention relates to the construction of a sliding strip for the drive plate of a magnetic levitation railway.

Stand der TechnikState of the art

Gleitleisten haben bei Fahrplatten von Magnetschwebebahnen die Aufgabe, im Notfall, z.B. bei Stromausfall, ein kontrolliertes Abbremsen des Zuges zu gewährleisten. Hierzu bestehen die Gleitleisten (4) aus dickem Stahlblech, welches im Beton (1) der Fahrplatte (3) verankert ist.Sliding strips have in the case of platforms of magnetic levitation trains the task in an emergency, e.g. in case of power failure, to ensure a controlled braking of the train. For this purpose, there are the sliding strips (4) made of thick steel sheet, which in the concrete (1) of the drive plate (3) is anchored.

Die Gleitleiste (4) ist dabei im Beton (1) versenkt und muß, um das Eindringen von Wasser in den Spalt zwischen Metall (4) und Beton (1) zu verhindern, aufwendig gegen den Beton (1) abgedichtet sein.The sliding strip (4) is recessed in the concrete (1) and must, in order to prevent the ingress of water into the gap between the metal (4) and concrete (1), be sealed against the concrete (1).

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist eine einfachere Lösung, die keine Dichtigkeitsprobleme mehr aufweist und witterungsbeständig ist.The object of the invention is a simpler solution that has no more leakage problems and is weather-resistant.

Darstellung der ErfindungPresentation of the invention

Die Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.The object is solved by the features specified in the characterizing part of claim 1.

Wesentliches Merkmal der Erfindung ist hierbei, die Stahlgleitleiste (4) durch eine flächige Betongleitleiste (2) zu ersetzen, die keinen senkrechten Spalt zwischen dem Beton (1) der Fahrplatte (3) und der Gleitleiste (2) mehr aufweist, in den Wasser von oben eindringen könnte.An essential feature of the invention is in this case to replace the steel sliding strip (4) by a flat concrete sliding strip (2), which has no vertical gap between the concrete (1) of the drive plate (3) and the slide strip (2) in the water of could penetrate above.

Die Gleitleiste (2) besteht aus einem hochfesten oder ultrahochfesten Beton mit speziellen harten Zuschlagstoffen, der eine äußerst glatte, abriebfeste und dauerhafte Oberfläche aufweist.The sliding strip (2) consists of a high-strength or ultra-high-strength concrete with special hard aggregates, which has an extremely smooth, abrasion-resistant and durable surface.

Obwohl auf Beton sonst nur rollende Systeme schadensfrei bewegt werden können, eignet sich dieser Beton dazu, ein auf ihm auf Gleitkufen abgesetztes Magnetschwebefahrzeug gleichmäßig über einen langen Weg und ohne einen zu reparierenden Schaden an der Gleitleiste (2) zum Stillstand zu bringen.Although on concrete otherwise only rolling systems can be moved without damage, this concrete is suitable for bringing a magnetic levitation vehicle placed on it on skids evenly over a long distance and without damage to the sliding strip (2) to be repaired.

Die erfindungsgemäße Betongleitleiste (2) benötigt auch keine senkrechten Verankerungen im Beton (1) der Fahrplatte (3), sondern ist bevorzugt flächig mit diesem verbunden und verzahnt. Dies geschieht vorzugsweise, indem in einer Schalung der noch flüssige hochfeste oder ultrahochfeste Beton der Gleitleiste (2), eventuell mit verbindender Anschlußbewehrung dazwischen, mit dem flüssigen Konstruktionsbeton (1) der Tragplatte (3) überschichtet wird.The Betongleitleiste invention (2) also requires no vertical anchorages in the concrete (1) of the drive plate (3), but is preferably connected flatly and interlocked with this. This is preferably done by in a formwork of the still liquid high-strength or ultra-high-strength concrete of the sliding strip (2), possibly with connecting connecting reinforcement therebetween, with the liquid structural concrete (1) of the support plate (3) is covered.

Es ist weiterhin möglich, eine aus dem Spezialbeton vorgefertigte Gleitleiste in die Schalung einzulegen und mit dem Konstruktionsbeton zu vergießen. Auf diese Weise ist es auch einfach möglich, nur diejenigen Teilbereiche der Oberfläche der Tragplatte (3), auf denen das Magnetschwebefahrzeug notfalls absetzt, mit Spezialbeton als Gleitleiste (2) zu versehen.It is also possible to insert a prefabricated from the special concrete slide bar in the formwork and shed with the structural concrete. In this way it is also easily possible to provide only those portions of the surface of the support plate (3) on which the magnetic levitation vehicle, if necessary, settles with special concrete as a sliding strip (2).

Dabei sind sowohl mechanische als auch chemische Verbundmittel möglich, um den Spezialbeton der Betongleitleiste (2) mit dem Konstruktionsbeton (1) der Fahrplatte (3) dauerhaft zu verbinden.In this case, both mechanical and chemical composite means are possible to permanently connect the special concrete concrete slab (2) with the structural concrete (1) of the drive plate (3).

Der Spezialbeton weist vorzugsweise eine Schichtdicke von etwa 5 Zentimetern auf.The special concrete preferably has a layer thickness of about 5 centimeters.

Die Figuren zeigen schematisch die erfindungsgemäße Betongleitleiste (2) im Vergleich zum Stand der Technik, der Stahlgleitleiste (4).

  • Fig. 1 zeigt schematisch die Stahlgleitleiste als den Stand der Technik
  • Fig. 2 zeigt eine Fahrplatte (3), bei der die gesamte Oberseite aus einem ultrahochfesten Beton als Gleitleiste (2), sozusagen als Gleitfläche und gänzlich ohne senkrechte Spalte, ausgestaltet ist.
  • Fig. 3 zeigt eine Fahrplatte (3), bei der die Gleitleiste (2) nur einen Teil der Oberseite der Fahrplatte (3) einnimmt und die senkrechten Fugen durch den guten Verbund der beiden Betons Konstruktionsbeton(1)/ultrahochfester Beton nur von verschwindendem Ausmaß sind.
The figures show schematically the Betongleitleiste (2) according to the invention in comparison to the prior art, the Stahlgleitleiste (4).
  • Fig. 1 shows schematically the Stahlgleitleiste as the prior art
  • Fig. 2 shows a drive plate (3), in which the entire upper side of an ultra-high-strength concrete as sliding strip (2), so to speak as a sliding surface and entirely without vertical column, is configured.
  • Fig. 3 shows a drive plate (3), in which the slide strip (2) occupies only part of the top of the drive plate (3) and the vertical joints by the good bond of the two concrete construction concrete (1) / ultra-high-strength concrete only of vanishing extent are.
