The shuttering consists of two rows of shuttering boards (20,21) which lie adjacent to each other in each row.

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Einbau von Schienen im Gleisbau sowie auf die Verwendung einer Mischpistole zu diesem Einbau.The invention relates to a method and a Device for installing rails in track construction and on the use of a mixing gun for this installation.

Ein Einbauverfahren mit den Schritten a), b) und c) ist aus der EP 0 180 118 B1 bekannt. Dort werden wieder entfernbare Verschalungen auf ein Betonbett aufgesetzt, und die Zwischenräume zwischen Fuß und Betonbett sowie zwischen den Verschalungen und der Schiene wird mit einer Masse ausgegossen. Die Verschalungen weisen an ihrer Innenseite Stufen und Kanten auf, so daß nach Entfernen der Verschalungen diese Stufen und Kanten an der Vergußmasse ausgeprägt sind. Wenn diese ummantelte Schiene in einen Straßenbaukörper einzubeziehen ist, wird gewöhnlich eine Betonschicht hergestellt, welche diese Stufen und Kanten umhüllt. Während des Befahrens der Schiene durch eine Straßenbahn kommt es zu heftigen Schwingungen der umhüllten Schiene, und es hat sich gezeigt, daß an den Stufen und Kanten wilde Risse im Beton entstehen.An installation procedure with steps a), b) and c) is known from EP 0 180 118 B1. There will be again removable coverings placed on a concrete bed, and the spaces between the foot and the concrete bed and between The formwork and the rail are made with one mass poured out. The casings face on the inside Steps and edges on, so that after removing the Cladding these steps and edges on the sealing compound are pronounced. If this covered rail into one Road structures are usually included Concrete layer made which these steps and edges envelops. While driving on the rail by a Tram there is violent vibrations of the enveloped Rail, and it has been shown that on the steps and Edges create wild cracks in the concrete.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, bei deren Anwendung die beschriebenen Risse nicht auftreten und welche den Einbau der Schiene in die Straße erleichtern und verbilligen.The invention is based on the object To create methods and an apparatus in the Application the cracks described do not occur and which ones facilitate the installation of the rail in the street and cheaper.

Die gestellte Aufgabe wird durch das Verfahren nach Anspruch 1 sowie die Vorrichtung gemäß Anspruch 6 gelöst. Anspruch 16 befaßt sich mit der Anwendung einer angepaßten Mischpistole.The task is followed by the procedure Claim 1 and the device according to claim 6 solved. Claim 16 deals with the application of an adapted Mixing gun.

Die Einbauvorrichtung dient einem doppelten Zweck: Während des Einbaus der Straßenbahnschiene ist sie als Schalung für die unter den Schienenfuß einzubringende Einbaumasse (Polyurethan) nützlich, und nach dem Einbau dient sie (unmittelbar oder mittelbar) als Trennelement zwischen der durch die elastisch gelagerte Schiene und die Füllelemente gebildeten Einheit und dem angrenzenden Straßenbelag. Von besonderer Bedeutung ist es, daß Polyurethan-Komponentenmischung maschinell eingebracht werden kann, und daß mit einer Polyurethan-Mischung aus zwei oder mehreren Komponenten gearbeitet werden kann. Entweder stellt man die Schienenkammer-Füllelemente mit Nuten her, die von oben nach unten reichen und von der Einschalung abgedeckt werden, um Einfüllkanäle zu bilden, oder zwischen dem oberen und unteren Abschnitt der Schalungsvorrichtung befinden sich Einspritzlöcher. Durch diese Einspritzkanäle erfolgt das maschinelle Einfüllen des flüssigen Polyurethans. Nach unten verbreitert sich der Schalungskanal, was das vollständige Unterfüllen des Schienenfußes bewirkt.The mounting device serves a dual purpose: During the installation of the tram rail it is as Formwork for the to be inserted under the rail foot Installation dimensions (polyurethane) useful, and after installation it serves (directly or indirectly) as a separating element between the by the elastically mounted rail and the Filler elements formed unit and the adjacent Road surface. It is of particular importance that Polyurethane component mixture introduced by machine can be, and that with a polyurethane mixture of two or several components can be worked. Either you make the rail chamber fillers with grooves, that go from top to bottom and from the formwork be covered to form filling channels, or between the upper and lower section of the formwork device there are injection holes. Through these injection channels the liquid is filled mechanically Polyurethane. The widens downwards Formwork channel, what the complete underfilling of the Rail foot causes.

Die dargestellte Straßenbahnschiene 1 weist einen Kopf 2, einen Steg 3 und einen Fuß 4 auf. Im Kopf 2 befindet sich eine Rille 5, und zwischen Kopf und Fuß sind Kammern 6 und 7 gebildet. Bei einem Gleis ist noch eine weitere, nicht dargestellte Schiene vorhanden, die über eine Spurstange 8 mit der dargestellten Schiene 1 verbunden ist. Die Spurstange 8 ist am Steg 3 verschraubt, wie bei 9 dargestellt. Die Kammer 6 ist durch ein Kammerfüllelement 10 und die Kammer 7 durch ein Kammerfüllelement 11 ausgefüllt. Wie ersichtlich, weisen die Kammerfüllelemente 10, 11 Aussparungen 12, 13 im Bereich der Verschraubung 9 auf. Die Kammerfüllelemente 10, 11 weisen eine gewisse Länge, beispielsweise von 75 cm, auf, und das Kammerfüllelement 11 hört gerade an der Spurstange 8 auf. Die Kammerfüllelemente 10, 11 sind in ihre jeweiligen Kammern 6, 7 fest eingeklebt. Ferner kann auf der Unterseite des Fußes 4 eine Nachgiebigkeitsschicht 14 angebracht sein, die sich über eine Ausfüll- oder Unterfütterungsschicht 15 aus Polyurethan am Untergrund 16, meist aus Beton, abstützt. Die Nachgiebigkeitsschicht 14 besteht aus polyurethangebundenem Kork oder einem anderen Material mit ähnlichem Nachgiebigkeitsverhalten. Die nachgiebige Lagerung der Schiene 1 bewirkt, daß beim Befahren der Schiene 1 durch eine Straßenbahn die Anregung von höherfrequenten Schwingungen weitgehend vermieden wird und die auftretenden Schwingungen durch Walkarbeit in den Elementen 10, 11 und 14 sowie der eingegossenen Unterfütterungsschicht 15 gedämpft werden.The tram rail 1 shown has one Head 2, a web 3 and a foot 4 on. Located in head 2 there is a groove 5 and there are chambers 6 between the head and the foot and 7 formed. With one track there is another one, not shown rail available, which has a tie rod 8th is connected to the rail 1 shown. The Tie rod 8 is screwed to web 3, as in 9 shown. The chamber 6 is through a chamber filling element 10 and the chamber 7 filled by a chamber filling element 11. As can be seen, the chamber filling elements 10, 11 Cutouts 12, 13 in the area of the screw connection 9. The Chamber filling elements 10, 11 have a certain length, for example of 75 cm, and the chamber filling element 11 just stops at tie rod 8. The chamber filling elements 10, 11 are firmly glued into their respective chambers 6, 7. Furthermore, a on the bottom of the foot 4 Compliance layer 14 may be attached, which over a filling or relining layer 15 made of polyurethane on the underground 16, usually made of concrete. The Resilience layer 14 consists of polyurethane-bonded Cork or other material with similar Compliance behavior. The resilient storage of the Rail 1 causes that when driving on the rail 1 through a tram the excitation of higher frequencies Vibration is largely avoided and the occurring Vibrations through flexing work in elements 10, 11 and 14 and the cast relining layer 15 are damped will.

Nachfolgend wird die Herstellung der Unterfütterungsschicht 15 aus Polyurethan beschrieben. Die Schiene 1 mit den angeklebten Elementen 10, 11 und 14 wird höhengerecht oberhalb der Unterlage 16 verlegt, wobei der Abstand zwischen der Unterseite der Schiene und der Betonunterlage 16 etwas schwanken kann, bedingt durch die Herstellungsungenauigkeit der Oberfläche der Schicht 16. Anschließend werden zwei Reihen von Schalungplanken 20, 21 an die Außenseiten der Kammerfüllelemente 10, 11 angelegt und beispielsweise mittels Klammern, welche den Schienenkopf 2 überbrücken, festgelegt. Die Schalungsplanken 20, 21 können auch mittels Nägeln oder Schrauben an den Kammerfüllelementen festgemacht werden, und hierzu sind Befestigungslöcher 33, 34 (Fig. 2, 3) im oberen Abschnitt 22 vorgesehen. Die Schalungsplanken 20, 21 weisen jeweils einen oberen Abschnitt 22, einen unteren Abschnitt 23 und einen Zwischenabschnitt 24 auf und bestehen aus Kunststoffmaterial oder Aluminium von beispielsweise 3 mm Dicke oder aus Stahlblech. Der Abschnitt 23 weist einen nach innen gerichteten Fußsteg 25 auf, dessen Breite zwischen 10 und 30 mm betragen kann. Der Zwischenabschnitt 24 bildet eine unter 20° gegenüber der Vertikalen geneigte Schrägfläche oder Flanke und ist von Öffnungen 26 und gegebenenfalls 29 durchbrochen, die in Längsrichtung in der Schalungsplanke im Abstand von etwa 50 cm verteilt angeordnet sind. Die Öffnungen 26 dienen zum Einfüllen von flüssigem Polyurethan, und die Öffnungen 29 zum Beobachten der kompletten Füllung bei undurchsichtigen Elementen. Auch im Fußsteg 25 sind Aussparungen 27 vorgesehen. Die Planken weisen eine Länge von 1,5 m auf (auch andere Längen von z.B. 78 cm sind brauchbar) und können dort, wo sie an die Spurstange 8 anstoßen, mit einer passenden Aussparung 28 versehen sein, um die jeweilige Spurstange zu umgreifen. Wichtig ist, daß die Schalungselemente 20, 21 an ihrem Stumpf- oder Überlappungsstoß eng beieinander liegen. Der Stumpfstoß kann gegebenenfalls durch Dichtungsband oder dergleichen abgedichtet werden.The following is the production of the Relining layer 15 made of polyurethane is described. The Rail 1 with the glued elements 10, 11 and 14 is installed in height above the base 16, the Distance between the bottom of the rail and the Concrete base 16 can fluctuate somewhat due to the Manufacturing inaccuracy of the surface of layer 16. Then two rows of formwork planks 20, 21 applied to the outside of the chamber filling elements 10, 11 and for example by means of brackets, which the rail head Bridge 2, set. The formwork planks 20, 21 can also be attached to the nails or screws Chamber filling elements are moored, and for this are Mounting holes 33, 34 (FIGS. 2, 3) in the upper section 22 intended. The formwork planks 20, 21 each have one upper section 22, lower section 23 and one Intermediate section 24 and consist of plastic material or aluminum, for example 3 mm thick or made of Sheet steel. The section 23 has one inwards footbridge 25, the width of which is between 10 and 30 mm can be. The intermediate section 24 forms an under Inclined surface inclined at 20 ° to the vertical or Flank and is of openings 26 and possibly 29th perforated in the longitudinal direction in the formwork plank in Distance of about 50 cm are arranged distributed. The Openings 26 are used to fill in liquid polyurethane, and the openings 29 for observing the complete filling with opaque elements. Also in footbridge 25 Recesses 27 are provided. The planks have a length from 1.5 m to (other lengths of e.g. 78 cm usable) and can be attached to the tie rod 8 abut, be provided with a suitable recess 28, to grasp the respective tie rod. It's important, that the formwork elements 20, 21 on their stump or The lap joint should be close together. The butt joint can if necessary by sealing tape or the like be sealed.

Fig. 4 zeigt die Bildung eines Einfüllkanals ohne Öffnung 26, mit Hilfe einer seitlichen Nut 36 im Kammerfüllelement 10 und der Schalung 20, welche die Nut 36 abdeckt. Die Nut 36 läuft im allgemeinen senkrecht von oben nach unten, und im Bereich des Schienenfußes 4 kann die Nut 36 trichterartig verbreitert sein, um die Ausbreitung der Unterfütterungsmasse zu begünstigen. Ein Nutabstand von 50 cm ist ausreichend.Fig. 4 shows the formation of a filler channel without Opening 26, using a lateral groove 36 in Chamber filling element 10 and the formwork 20, which the groove 36th covers. The groove 36 generally runs vertically from above down, and in the area of the rail foot 4, the groove 36 widened like a funnel to prevent the spread of the Favor relining mass. A groove spacing of 50 cm is sufficient.

Fig. 5 zeigt eine Variante, bei der das Kammerfüllelement 10 etwas verbreitert ist und einen Überstand über den Schienenfuß 4 aufweist, um den geneigten Zwischenabschnitt 24 bei der Schalungsplanke 20 zu vermeiden.Fig. 5 shows a variant in which the Chamber filling element 10 is somewhat widened and one Has protrusion on the rail base 4 to the inclined Intermediate section 24 at the formwork plank 20 too avoid.

Die Unterfütterungsschicht 15 wird durch Einspritzen von flüssiger Polyurethan-Komponentenmischung über die Einfüllöffnungen 26 oder die Einfüllkanäle 36 erzeugt. Die vollständige Füllung des Raumes unterhalb des Schienenfußes 4, 14 kann entweder an den Entlüftungsöffnungen 29 des Elements 21 beobachtet werden, oder die Planken bestehen aus durchsichtigem Kunststoff. Man kann mit einer Dosiermaschine entlang der Schiene 1 fahren und über eine Mischpistole 30 so lange in jede Öffnung 26 oder Kanal 36 flüssiges Polyurethan einspritzen, bis dieses an der Öffnung 29 des Elements 21 austritt. Die Mischpistole 30 weist ein Einspritzrohr 31 auf, das z.B. einen Durchmesser von 10 mm besitzt. Die Weite der Einfüllöffnung 26 bzw. die Tiefe des Kanals 36 richtet sich nach diesem Durchmesser und beträgt wenigstens 12 bis 20 mm. Die Langlochform der Öffnungn 26 (Fig. 2) wird bevorzugt, um das Einspritzrohr 31 längs der Schiene 1 schwenken zu können. Die Aussparungen 27 dienen zur Verklebung des Fußes 25 mittels des Polyurethans auf der Schicht 16. Es ist auch möglich, den Fuß klein oder fehlend und ohne Aussparung 27 zu gestalten, was vor allem dann in Betracht kommt, wenn die Schalungen nach Erhärten der Unterfütterungsschicht 15 demontiert und erneut verwendet werden sollen.The relining layer 15 is made by injection of liquid polyurethane component mixture over the Filling openings 26 or the filling channels 36 are generated. The complete filling of the space below the rail foot 4, 14 can either at the ventilation openings 29 of the Elements 21 are observed, or the planks are made of clear plastic. You can use a dosing machine Drive along the rail 1 and via a mixing gun 30 liquid into each opening 26 or channel 36 so long Inject polyurethane until it is at the opening 29 of the Elements 21 exits. The mixing gun 30 has a Injection tube 31, which e.g. a diameter of 10 mm owns. The width of the fill opening 26 or the depth of the Channel 36 depends on this diameter and is at least 12 to 20 mm. The elongated shape of the openings 26 (Fig. 2) is preferred to the injection pipe 31 along the To be able to pivot rail 1. The recesses 27 serve for gluing the foot 25 by means of the polyurethane on the Layer 16. It is also possible to have the foot small or absent and to design without recess 27, which is then especially in Comes into consideration if the formwork after hardening of the Relining layer 15 disassembled and used again should be.

Nach Aushärtung des Polyurethans der Schicht 15 wird der Straßenbelag hergestellt, der gewöhnlich eine Betonschicht 17, eine oder zwei Asphaltschichten 18 und einen Fugenverguß 19 an der Schiene umfaßt. Statt der Beton- und Asphaltschichten kann auch Pflaster verwendet werden. Durch entsprechende Präparation des Kopfes 2 sorgt der Fugenverguß 19 dafür, daß keine Feuchtigkeit von der Straßenoberseite in die Straßen- und Gleiskonstruktion eindringen kann. Das Material der Schicht 19 ist genügend elastisch und klebefähig, so daß zur Bitumenschicht 18 (oder zum Pflaster) keine Risse vorkommen. Dagegen gibt es einen Spalt zwischen der Innenseite des oberen Abschnittes der jeweiligen Planke 20, 21 und dem angrenzenden Kammerfüllelement 10 bzw. 11. Somit können die Kammerfüllkörper 10, 11 schwingen, ohne wilde Risse in der Betonschicht 17 zu erzeugen. Die Schrägfläche 24 stellt keine Gefahr für Rißbildung dar, d.h. beim Beton der Schicht 17 entstehen keine Ecken oder Kanten, von denen Risse ausgehen können.After curing of the polyurethane, the layer 15 is the road surface made, usually one Concrete layer 17, one or two asphalt layers 18 and includes a grout 19 on the rail. Instead of the concrete and Asphalt layers can also be used in pavement. By appropriate preparation of the head 2, the Joint potting 19 to ensure that no moisture from the Street top in the road and track construction can penetrate. The material of layer 19 is sufficient elastic and adhesive, so that the bitumen layer 18 (or to the pavement) there are no cracks. There is one against it Gap between the inside of the upper section of the respective plank 20, 21 and the adjacent Chamber filling element 10 and 11, respectively Chamber filler 10, 11 swing without wild cracks in the To produce concrete layer 17. The inclined surface 24 provides no risk of cracking, i.e. for the concrete of the layer 17 there are no corners or edges from which cracks can go out.

Mit der Erfindung wird somit eine Entkopplungsvorrichtung geschaffen, mit der die Rißbildung in Straßenbelagschichten weitgehend vermieden wird, und die gleichzeitig als Schalung bei der Herstellung der Unterfütterungsschicht 15 dient. Die Schalung 20, 21 ermöglicht das maschinelle Füllen des Raumes unter dem Schienenfuß ohne Abfall an PU-Material und ohne Ausbildung eines für die Straßenkonstruktion ungeeigneten unregelmäßigen Wulstes.With the invention is thus a Decoupling device created with which the cracking is largely avoided in road surface layers, and the at the same time as formwork in the manufacture of the Relining layer 15 is used. The formwork 20, 21 enables the mechanical filling of the space under the Rail foot without waste of PU material and without training one unsuitable for road construction irregular bead.

Die Höhe der Schalung kann dem Zweck der Entkopplung zwischen den Kammerfüllelementen 10, 11 und den Betonschichten 17 angepaßt werden. Durch Wahl einer geringeren Höhe des Abschnitts 22 kann die mechanische Restankopplung vergrößert und durch eine größere Höhe kann die Restankopplung verringert werden, wodurch sich eine Steuerungsmöglichkeit für das Dämpfungsverhalten des Gesamtaufbaus ergibt. Dies gilt auch, wenn die Schalungselemente entfernt werden, wobei dann die stärkere Ankopplung erzielt wird, ohne jedoch der Gefahr der Rißbildung im Beton 17 zu unterliegen. Die Randumhüllung 35 am Schienengfuß 4, 14 ist relativ weich und wenig ausladend, so daß von ihr keine wilden Risse in den Beton ausgehen. Im Falle der Fig. 5 wird vermieden, daß die Randumhüllung überhaupt vorsteht, und es können vereinfachte Planken verwendet werden. Anstelle der Verwendung von Planken zum Aufbau der Schalung kann auch aufgerolltes Band verwendet werden.The height of the formwork can serve the purpose of decoupling between the chamber filling elements 10, 11 and Concrete layers 17 are adapted. By choosing one lower height of section 22 may be mechanical Residual coupling can be increased and increased in height the residual coupling can be reduced, resulting in a Control option for the damping behavior of the Overall structure results. This also applies if the Formwork elements are removed, then the stronger Coupling is achieved without the risk of Cracking in concrete 17 to be subject. The edge wrap 35 at the narrow leg 4, 14 is relatively soft and not very bulky, so that there are no wild cracks in the concrete. in the 5 is avoided that the edge wrapping protrudes at all, and there can be simplified planks be used. Instead of using planks for Structure of the formwork can also be used rolled tape will.
