Description

Die Erfindung betrifft eine Einrichtung zum Abdecken mindestens eines Bauteils eines Befestigungssystems für einen Befestigungspunkt, in dem eine Schiene für ein Schienenfahrzeug an einem Untergrund befestigt ist, nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for covering at least one component of a fastening system for a fastening point in which a rail for a rail vehicle is fastened to a base, according to the preamble of claim 1.

Des Weiteren betrifft die Erfindung einen Befestigungspunkt, in dem eine Schiene für ein Schienenfahrzeug auf einem Untergrund befestigt ist, das ein gegen den Untergrund im montierten Zustand verspanntes Federelement umfasst, das eine elastische Niederhaltekraft auf den Fuß der Schiene ausübt.Furthermore, the invention relates to a fastening point in which a rail for a rail vehicle is fastened to a base, which comprises a spring element braced against the base in the mounted state, which exerts an elastic hold-down force on the foot of the rail.

Typischerweise handelt es sich bei dem Untergrund um eine Betonschwelle oder -platte. Die Erfindung eignet sich jedoch auch für die Anwendung bei Untergründen, die aus Holz, Stahl, Kunststoff und desgleichen bestehen.Typically, the substrate is a concrete sleeper or slab. However, the invention is also suitable for use with substrates made of wood, steel, plastic and the like.

Befestigungssysteme der hier in Rede stehenden Art dienen insbesondere zur Befestigung von Schienen von Straßenbahnen und desgleichen. Im innerstädtischen Bereich sind solche Schienen beispielsweise dann, wenn sie im Bereich einer Straße oder eines Gehwegs verlegt sind, typischerweise in eine seitlich bis an ihren Schienenkopf angefüllte Füllmasse eingelassen, bei der es sich beispielsweise um einen gegebenenfalls mehrschichtigen Bodenbelag der jeweiligen Straße oder des jeweiligen Gehwegs handeln kann.Fastening systems of the type in question are used in particular for fastening rails of trams and the like. In inner-city areas, for example, if they are laid in the area of a street or a sidewalk, such rails are typically embedded in a filling compound that is filled laterally up to their rail head, which is, for example, an optionally multi-layered floor covering of the respective street or the respective sidewalk can act.

Um eine im Hinblick auf das Verschleißverhalten und den Fahrkomfort optimale Befestigung der Schiene zu ermöglichen, sind die Schienen in der Regel nicht starr im jeweiligen Befestigungspunkt montiert, sondern werden in Richtung des Untergrunds federnd elastisch niedergehalten. Dazu weisen Befestigungssysteme der hier in Rede stehenden Art üblicherweise mindestens ein Federelement auf, das gegen den Fuß der Schiene wirkt und die Schiene elastisch gegen den jeweiligen Untergrund drückt. Um dabei auch bei festen Untergründen eine definierte Nachgiebigkeit in Schwerkraftrichtung zu gewährleisten, kann zwischen dem Schienenfuß und dem Untergrund mindestens eine nachgiebige Platte angeordnet sein. Aus dem Stand der Technik bekannte Befestigungssysteme für Befestigungspunkte, die nach diesem Prinzip aufgebaut und für Straßenbahnschienen und desgleichen vorgesehen sind, sind beispielsweise in der DE 10 2009 041 112 B4 beschrieben.In order to enable the rails to be fastened in the best possible way in terms of wear behavior and driving comfort, the rails are generally not rigidly mounted at the respective fastening point, but are held down elastically in the direction of the ground. For this purpose, fastening systems of the type in question usually have at least one spring element which acts against the foot of the rail and elastically presses the rail against the respective subsurface. In order to ensure a defined resilience in the direction of gravity even with solid subsoil, at least one flexible plate can be arranged between the rail foot and the subsoil. Fastening systems for fastening points known from the prior art, which are constructed according to this principle and are intended for tram rails and the like are, for example, in the DE 10 2009 041 112 B4 described.

Damit bei solchen Befestigungssystemen das Federelement trotz des den Befestigungspunkt umgebenden Materials im Gebrauch frei schwingen kann, wird in der Praxis mindestens auf das Federelement des jeweiligen Befestigungssystems eine Abdeckkappe gesetzt. Das Federelement sitzt dann in der ihm zugeordneten, von der Abdeckkappe umgrenzten Ausnehmung und ist so gegenüber dem umgebenden Füllmaterial abgeschirmt. Die Ausnehmung der Abdeckkappe ist dabei so dimensioniert, dass ein für die ungehinderte Bewegung des Federelements ausreichender Abstand zwischen den Innenflächen der Abdeckkappe und dem Federelement besteht.So that with such fastening systems the spring element can oscillate freely during use despite the material surrounding the fastening point, in practice a covering cap is placed at least on the spring element of the respective fastening system. The spring element then sits in the recess which is assigned to it and is delimited by the covering cap and is thus shielded from the surrounding filling material. The recess of the covering cap is dimensioned in such a way that there is a sufficient distance between the inner surfaces of the covering cap and the spring element for the unhindered movement of the spring element.

Um die Schallemissionen zu minimieren, können in Befestigungspunkten der voranstehend erläuterten Art befestigte Schienen an ihren Schienenstegen mit Formteilen belegt sein, durch die der beim Überfahren der Schiene durch ein Schienenfahrzeug ausgelöste Körperschall reduziert werden soll (s. DE 40 04 208 C2 ). Neben dem voranstehend erläuterten Stand der Technik ist aus der CN 203 429 513 U ein Befestigungssystem für einen Schienenbefestigungspunkt bekannt, bei dem ein genanntes Kammerfüllelement dicht an einer ihm zugeordneten Seite des Schienenstegs einer in dem Befestigungspunkt befestigten Schiene anliegt. Dabei ist eine haubenartige Abdeckkappe gegen die Längsseite des zugeordneten Kammerfüllelements abgestützt, die die Bauteile des Befestigungssystems auf der vom Kammerfüllelement abgewandten Seiten gegenüber den den Befestigungspunkt umgebenden Untergrund U abschotten. Um einen sicheren Halt des Abdeckelements zu gewährleisten, ist das Abdeckelement durch Nägel oder Schrauben fest mit dem Kammerfüllelement verbunden.In order to minimize noise emissions, rails fastened in fastening points of the type described above can be fitted with molded parts on their rail webs, which are intended to reduce the structure-borne noise caused when a rail vehicle drives over the rail (see Fig. DE 40 04 208 C2 ). In addition to the prior art explained above is from the CN 203 429 513 U a fastening system for a rail fastening point is known, in which a said chamber filling element bears tightly against an associated side of the rail web of a rail fastened in the fastening point. A hood-like cover cap is supported against the long side of the associated chamber filling element, which faces the components of the fastening system on the side facing away from the chamber filling element seal off the underground U surrounding the attachment point. In order to ensure that the cover element is held securely, the cover element is firmly connected to the chamber filling element by nails or screws.

Schließlich ist aus der EP 0 374 325 A1 ein Befestigungssystem für einen Befestigungspunkt bekannt, das ein Federelement umfasst, das gegen einen Untergrund verspannt ist und mit seinen Haltearmen elastisch gegen den Fuß einer in dem Befestigungspunkt zu befestigenden Schiene wirkt. Das Halteelement ist dabei leistenförmig gestaltet und erstreckt sich über viele entlang der Schiene angeordnete gleichartige Befestigungspunkte. Dabei ist das Halteelement einerseits zwischen dem freien Ende des Haltearms des Federelements gegen den Schienenfuß geklemmt gehalten und bildet andererseits einen Anschlag für den Fuß einer Abdeckkappe, die sich entsprechend der Länge des Halteelements entlang der Schiene über eine Vielzahl von Befestigungspunkten erstreckt und diese gegenüber der Umgebung abschirmt, wobei der von der Abdeckkappe abgegrenzte Raum ausreichend groß ist für die notwenige federndelastische Beweglichkeit der Federelemente der Befestigungssysteme . Die leistenförmige, sich über eine Vielzahl von die Schiene haltenden Befestigungssystemen erstreckende Gestalt und die Art und Weise der Befestigung des Halteteils zwischen den Haltearmen der Federelemente der Befestigungssysteme und dem Schienenfuß der Schiene bedingen, dass das Halteteil auf dem Schienenfuß angeordnet wird, bevor die Federelemente der Befestigungssysteme montiert werden. Zum Abschluss der Montagearbeiten wird schließlich die Abdeckkappe über die Befestigungselemente gesetzt und an dem Halteelement abgestützt.Finally is out of the EP 0 374 325 A1 a fastening system for a fastening point is known, which comprises a spring element which is braced against a substrate and with its holding arms acts elastically against the base of a rail to be fastened in the fastening point. The retaining element is in the form of a strip and extends over many similar fastening points arranged along the rail. The holding element is held clamped against the foot of the rail on the one hand between the free end of the holding arm of the spring element and forms a stop for the foot of a cover cap on the other hand, which extends along the rail over a large number of attachment points corresponding to the length of the holding element and these in relation to the environment shields, the delimited by the cap space is large enough for the necessary resilient mobility of the spring elements of the fastening systems. The strip-shaped shape extending over a large number of fastening systems holding the rail and the way in which the holding part is fastened between the holding arms of the spring elements of the fastening systems and the rail foot of the rail mean that the holding part is arranged on the rail foot before the spring elements of the Fastening systems are mounted. Finally, to complete the assembly work, the cover cap is removed set the fasteners and supported on the support member.

Vor dem Hintergrund des Standes der Technik bestand die Aufgabe der Erfindung darin, eine Einrichtung zur Abdeckung eines Befestigungssystems für einen Befestigungspunkt zu schaffen, die sich auf einfache Weise lagerichtig montieren lässt und dabei eine sichere Funktion des Befestigungssystems und insbesondere seines Federelements gewährleistet.Against the background of the prior art, the object of the invention was to create a device for covering a fastening system for a fastening point, which can be easily installed in the correct position and thereby ensures reliable functioning of the fastening system and in particular its spring element.

Darüber hinaus sollte ein Befestigungssystem für einen Befestigungspunkt geschaffen werden, bei dem mit vergleichbar geringem Aufwand eine hohe Funktionssicherheit auch dann sichergestellt ist, wenn das Befestigungssystem in ein Füllmaterial eingebettet ist.In addition, a fastening system for a fastening point should be created in which a high level of functional reliability is also ensured with comparably little effort when the fastening system is embedded in a filling material.

In Bezug auf die Einrichtung zum Abdecken eines Befestigungssystems für einen Befestigungspunkt hat die Erfindung diese Aufgabe dadurch gelöst, dass eine solche Einrichtung gemäß Anspruch 1 ausgebildet ist.With regard to the device for covering a fastening system for a fastening point, the invention has achieved this object in that such a device is designed according to claim 1.

Ein die voranstehend genannte Aufgabe erfindungsgemäß lösendes Befestigungssystem für einen Befestigungspunkt, in dem eine Schiene für ein Schienenfahrzeug auf einem Untergrund befestigt ist, umfasst dementsprechend ein gegen den Untergrund verspanntes Federelement, das eine elastische Niederhaltekraft auf den Fuß der Schiene ausübt, und eine erfindungsgemäße Einrichtung, wobei

  • das Halteteil der Einrichtung zwischen dem Federelement und dem Untergrund angeordnet ist,
  • die Abdeckkappe über das Federelement gestülpt ist, um das Federelement gegenüber der Umgebung abzuschirmen, und
  • die Abdeckkappe durch eine formschlüssige Verbindung mit dem Halteteil lagegenau positioniert ist.
A fastening system that achieves the aforementioned object according to the invention for a fastening point, in which a rail for a rail vehicle is fastened to a base, accordingly comprises a spring element braced against the base, which exerts an elastic hold-down force on the base of the rail, and a device according to the invention, whereby
  • the holding part of the device is arranged between the spring element and the ground,
  • the cover cap is slipped over the spring element in order to shield the spring element from the environment, and
  • the cover cap is positioned precisely by means of a form-fitting connection with the holding part.

Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben und werden nachfolgend wie der allgemeine Erfindungsgedanke im Einzelnen erläutert.Advantageous refinements of the invention are specified in the dependent claims and are explained in detail below, along with the general idea of the invention.

Eine erfindungsgemäße Einrichtung zur Abdeckung eines Befestigungssystems für einen Befestigungspunkt, in dem eine Schiene für ein Schienenfahrzeug an einem Untergrund befestigt ist, weist in Übereinstimmung mit dem eingangs erläuterten Stand der Technik ein Federelement auf, das eine elastische Niederhaltekraft auf die Schiene ausübt, und umfasst ebenso wie aus dem Stand der Technik bekannte Einrichtungen dieser Art eine Abdeckkappe, die dazu vorgesehen ist, über das Federelement gestülpt zu werden, um das Federelement gegenüber der Umgebung abzuschirmen, wobei die Abdeckkappe eine Ausnehmung besitzt, die im über das Federelement gestülptem Zustand das Federelement aufnimmt und derart bemessen ist, dass das Federelement innerhalb der Ausnehmung den im Gebrauch auftretenden Bewegungen der Schiene frei folgen kann.A device according to the invention for covering a fastening system for a fastening point, in which a rail for a rail vehicle is fastened to a substrate, has, in accordance with the prior art explained at the outset, a spring element which exerts an elastic hold-down force on the rail, and also includes like devices of this type known from the prior art, a covering cap which is intended to be slipped over the spring element in order to shield the spring element from the environment, the covering cap having a recess which accommodates the spring element when it is slipped over the spring element and is dimensioned such that the spring element can freely follow the movements of the rail occurring during use within the recess.

Erfindungsgemäß umfasst dabei die Einrichtung, und ebenfalls wie aus dem Stand der Technik bereits bekannt, zusätzlich ein separat von der Abdeckkappe handhabbares Halteteil, welches dazu vorgesehen ist, im Bereich des Federelements angeordnet zu werden. Dabei weist das Halteteil mindestens ein Formelement auf, das als Anschlag für eine lagegenaue Positionierung der Abdeckkappe an dem Halteteil dient. Erfindungsgemäß weist das Halteteil mindestens einen Unterlegabschnitt auf, der bei der Montage unter einen zugeordneten Abschnitt des Federelements schiebbar ist.According to the invention, the device also includes, as is already known from the prior art, a holding part that can be handled separately from the covering cap and is intended to be arranged in the region of the spring element. The holding part has at least one Shaped element that serves as a stop for an accurate positioning of the cap on the holding part. According to the invention, the holding part has at least one underlay section which can be pushed under an associated section of the spring element during assembly.

Im auf das Halteteil aufgesetzten Zustand ist die Abdeckkappe einer erfindungsgemäßen Vorrichtung folglich durch den betreffenden Absatz des Halteteils in mindestens einem Freiheitsgrad ihrer Beweglichkeit so durch Formschluss festgelegt, dass eine unbeabsichtigte Bewegung der Abdeckkappe aus ihrer Sollposition in Bezug auf das von ihr vor einem Kontakt mit dem Füllmaterial oder allgemein der Umgebung zu schützenden Federelement verhindert ist.In the state placed on the holding part, the covering cap of a device according to the invention is consequently fixed by the relevant shoulder of the holding part in at least one degree of freedom of its mobility by a positive fit such that an unintentional movement of the covering cap from its desired position in relation to that of it before contact with the Filling material or generally the environment to be protected spring element is prevented.

Das erfindungsgemäß vorgesehene Halteteil ist dabei so ausgebildet, dass es sich problemlos nachträglich an einem schon bestehenden Befestigungspunkt positionieren lässt. Dabei ist es denkbar, das Halteteil derart auszubilden und anzuordnen, dass es sich im Bereich des zu schützenden Federelements befindet und so eine definierte Auflage für die Abdeckkappe bietet.The holding part provided according to the invention is designed in such a way that it can be subsequently positioned at an already existing attachment point without any problems. It is conceivable to design and arrange the holding part in such a way that it is located in the area of the spring element to be protected and thus offers a defined support for the covering cap.

Das zusätzliche Halteteil einer erfindungsgemäßen Vorrichtung erlaubt auf diese Weise eine Befestigung der Abdeckkappe unabhängig von den einzelnen Bauteilen des Befestigungssystems.In this way, the additional holding part of a device according to the invention allows the covering cap to be fastened independently of the individual components of the fastening system.

Insbesondere ist es bei einer erfindungsgemäßen Einrichtung nicht erforderlich, die Abdeckkappe beispielsweise mit dem Federelement selbst oder einem für das Spannen des Federelements vorgesehenen Spannelement, wie einer Spannschaube oder einem Keil, zu verrasten oder desgleichen.In particular, with a device according to the invention it is not necessary to lock the cover cap, for example, with the spring element itself or with a tensioning element provided for tensioning the spring element, such as a tensioning screw or a wedge, or the like.

Stattdessen ermöglicht das zusätzliche Halteteil einen sicheren, dichten Sitz der Abdeckkappe auch auf unebenen Untergründen, da die Abdeckkappe nicht auf der jeweiligen Oberfläche des Untergrunds, sondern auf der für ihren Sitz optimierten Oberfläche des Halteteils sitzt. Auf diese Weise lassen sich erfindungsgemäße Einrichtungen an unterschiedlich ausgebildeten Befestigungspunkten unabhängig von der jeweiligen Form der Bauteile einsetzen, solange die Abdeckkappe ausreichend groß dimensioniert ist, um zumindest das hinsichtlich seiner freien Beweglichkeit kritische Federelement aufzunehmen.Instead, the additional holding part enables a secure, tight fit of the cover cap, even on uneven surfaces Subsurfaces, since the cover cap does not sit on the respective surface of the subsurface, but on the surface of the holding part that is optimized for its seat. In this way, devices according to the invention can be used at differently designed fastening points, regardless of the respective shape of the components, as long as the cover cap is dimensioned sufficiently large to accommodate at least the spring element, which is critical in terms of its free mobility.

Infolge ihrer durch das Halteteil von der Formgebung der jeweiligen Oberfläche, auf der die Abdeckkappe zu positionieren ist, unabhängigen Funktion ist eine erfindungsgemäße Einrichtung insbesondere für den Einsatz an Befestigungssystemen geeignet, bei denen das Federelement auf einer so genannten Führungsplatte sitzt. Führungsplatten dieser Art dienen zur Führung der im Befestigungspunkt befestigten Schiene in einer zur Längserstreckung der Schiene quer ausgerichteten Richtung und weisen an ihrer Oberseite üblicherweise Formelemente auf, durch die das Federelement geführt und lagegesichert ist. Dementsprechend zerklüftet ist die für ein Aufsetzen der Abdeckkappe zur Verfügung stehende Oberfläche einer solchen Führungsplatte. Indem ein erfindungsgemäßes Halteteil auf die Führungsplatte im Bereich des Federelements aufgesetzt wird, wird dagegen eine ebene Aufsetzfläche für die Abdeckkappe zur Verfügung gestellt, welche nicht nur ein einfaches und sicheres Positionieren, sondern auch eine optimierte Dichtheit im Bereich des unvermeidbaren Fügespaltes zwischen Halteteil und Abdeckkappe gewährleistet.As a result of its function, which is independent of the shape of the respective surface on which the covering cap is to be positioned, due to the holding part, a device according to the invention is particularly suitable for use in fastening systems in which the spring element is seated on a so-called guide plate. Guide plates of this type serve to guide the rail fastened at the fastening point in a direction transverse to the longitudinal extension of the rail and usually have shaped elements on their upper side, through which the spring element is guided and secured in position. The surface of such a guide plate that is available for placing the covering cap is correspondingly fissured. By placing a holding part according to the invention on the guide plate in the area of the spring element, on the other hand, a flat contact surface is made available for the cover cap, which not only ensures simple and secure positioning, but also optimized tightness in the area of the unavoidable joint gap between the holding part and cover cap .

Durch die erfindungsgemäße Kombination aus einem Halteteil und einer Abdeckkappe lässt sich somit problemlos eine sichere Abschirmung der funktionskritischen Bauelemente eines Befestigungssystems für einen Befestigungspunkt erreichen. Erfindungsgemäße Einrichtungen sind daher insbesondere für solche Anwendungen geeignet, bei denen eine flüssige oder feinkörnige Füllmasse, wie flüssiger Beton, feiner Schotter, Split oder Kies zum Einsatz kommt.The combination according to the invention of a holding part and a covering cap thus makes it possible to reliably shield the functionally critical components of a fastening system for a fastening point without any problems. Devices according to the invention are therefore particularly suitable for applications in which a liquid or fine-grain filling material, such as liquid concrete, fine crushed stone, grit or gravel, is used.

Ein weiterer Vorteil der Erfindung ist, dass durch das Halteteil für die Anordnung der Abdeckkappe eine Bezugsfläche geschaffen ist, welche unabhängig von der Höhenlage des zu schützenden Federelements ist. Dementsprechend lassen sich erfindungsgemäße Vorrichtungen problemlos auch bei solchen Befestigungspunkten einsetzen, bei denen zwischen dem Untergrund und der Schiene eine variierende Anzahl von Unterlegplatten, Auflageprofilen oder desgleichen angeordnet sind, um Ungleichmäßigkeiten des Abstands zwischen dem Untergrund und dem Schienenfuß auszugleichen.A further advantage of the invention is that the holding part for the arrangement of the covering cap creates a reference surface which is independent of the height of the spring element to be protected. Accordingly, devices according to the invention can also be used without any problems at those attachment points where a varying number of shims, support profiles or the like are arranged between the subsurface and the rail in order to compensate for unevenness in the distance between the subsurface and the rail foot.

Genauso eignen sich erfindungsgemäße Einrichtungen zum Schutz von Schienenbefestigungen auch bei solchen Befestigungspunkten, bei denen die Spurweite des Gleises, zu dem die jeweils zu befestigende Schiene gehört, mittels an sich hierzu aus dem Stand der Technik bekannter Maßnahmen einstellbar ist.Devices according to the invention for protecting rail fastenings are also suitable for fastening points where the gauge of the track to which the rail to be fastened belongs can be adjusted by means of measures known from the prior art.

Bei dem Formelement, welches den Anschlag für die genaue Positionierung der Abdeckkappe auf dem Halteteil bildet, kann es sich um eine den Platz für die Abdeckkappe zumindest abschnittsweise umgrenzenden Steg und desgleichen handeln. Es kann sich jedoch auch um eine Erhebung, einen Vorsprung oder eine Einsenkung handeln, gegen die die Abdeckkappe im auf dem Halteteil positionierten Zustand wirkt. Um die Positionierung und den sicheren Halt der Abdeckkappe auf dem Halteteil zu sichern, kann es dabei zweckmäßig sein, wenn auch an der Abdeckkappe ein korrespondierend zum Formelement des Halteteils ausgebildetes Formelement vorgesehen ist und die Formelemente von Abdeckkappe und Halteteil formschlüssig miteinander in Eingriff bringbar sind. Auf diese Weise kann besonders einfach gewährleistet werden, dass die Abdeckkappe beim Anfüllen der Füllmasse ihre Position beibehält. Eine besonders praxisgerechte, auch hohen Belastungen standhaltende Lagesicherung ergibt sich dabei dann, wenn die Formelemente von Abdeckkappe und Halteteil derart ausgebildet sind, dass sie miteinander verrastbar sind, wobei es sich hier als besonders günstig erweist, wenn die Formelemente derart ausgebildet sind, dass ihre Verrastung lösbar ist, um eine einfache Zugänglichkeit des Befestigungspunktes für Wartungs- und Reparaturzwecke zu ermöglichen.The shaped element, which forms the stop for the exact positioning of the covering cap on the holding part, can be a web or the like that at least partially delimits the space for the covering cap. However, it can also be an elevation, a projection or act as a depression against which the cover cap acts when positioned on the holding part. In order to ensure the positioning and secure hold of the covering cap on the holding part, it can be expedient if a shaped element designed to correspond to the shaped element of the holding part is also provided on the covering cap and the shaped elements of the covering cap and holding part can be brought into positive engagement with one another. In this way it can be ensured in a particularly simple manner that the cover cap retains its position when the filling compound is filled. A particularly practical position securing that can also withstand high loads is achieved when the shaped elements of the cover cap and holding part are designed in such a way that they can be latched together, it proving to be particularly favorable here if the shaped elements are designed in such a way that their latching is detachable to allow easy accessibility of the attachment point for maintenance and repair purposes.

Alternativ oder ergänzend zur formschlüssigen Verkopplung ist es selbstverständlich ebenso denkbar, die Haltekappe nach ihrer mit Hilfe des am Halteteil vorgesehenen anschlagartigen Formelements erfolgten lagerichtigen Positionierung mittels eines geeigneten Klebers oder eines zusätzlichen Befestigungselements, wie einer Klammer oder einer Schraube, zu sichern.As an alternative or in addition to positive coupling, it is of course also conceivable to secure the retaining cap with a suitable adhesive or an additional fastening element such as a clamp or a screw after it has been positioned in the correct position with the aid of the stop-like shaped element provided on the retaining part.

Um eine lagegenaue Ausrichtung in Bezug auf das zu schützende Federelement zu erleichtern, kann es zudem vorteilhaft sein, wenn das Halteteil ein Formelement aufweist, das als Anschlag zum lagegenauen Positionieren des Halteteils an dem Federelement dient. Dieses Formelement kann nach Art eines Abstandhalters oder desgleichen derart geformt und an dem Halteteil angeordnet sein, dass das Halteteil oder die Abdeckkappe bei seiner Montage selbsttätig seine optimale Montageposition in Bezug auf das Federelement findet. Dabei wirkt es optimalerweise gegen einen Abschnitt des Federelements, der im Gebrauch allenfalls geringe Bewegungen ausführt.In order to facilitate precise alignment with respect to the spring element to be protected, it can also be advantageous if the holding part has a shaped element that serves as a stop for positioning the holding part on the spring element in a precise position. This form element can be in the manner of a Be spacer or the like shaped and arranged on the holding part that the holding part or the cap automatically finds its optimal mounting position in relation to the spring element during its assembly. It works optimally against a section of the spring element that performs at most minor movements during use.

Insbesondere die nachträgliche Montage der erfindungsgemäßen Einrichtung an einem schon fertig montierten Befestigungssystem kann dadurch weiter erleichtert werden, dass das Halteteil nach Art eines Rahmens ausgebildet ist und eine Aufnahme umgrenzt, in der das Federelement bei an ihm positioniertem Halteteil sitzt.In particular, the subsequent installation of the device according to the invention on an already installed fastening system can be further facilitated by the fact that the holding part is designed like a frame and delimits a receptacle in which the spring element sits when the holding part is positioned on it.

Indem das Halteteil mindestens einen Unterlegabschnitt aufweist, der bei der Montage unter einen zugeordneten Abschnitt des Federelements schiebbar ist, der Unterlegabschnitt nach der Montage unter dem Federelement, also beispielsweise zwischen dem Federelement und der Oberfläche angeordnet ist, auf der das Federelement abgestützt ist, kann das Halteteil auch in einer vertikalen Richtung in Bezug auf das Federelement festgelegt werden, ohne dass es dazu zusätzlicher Befestigungsmittel bedarf. Indem das Halteteil zwei Unterlegabschnitte aufweist, von denen der eine Unterlegabschnitt einem Abschnitt des Federelements und der andere Unterlegabschnitt einem anderen Abschnitt des Federelements zugeordnet ist, lässt sich dazu die in der Regel symmetrische Formgebung von in Befestigungssysteme der hier in Rede stehenden Art zum Einsatz kommenden Federelementen nutzen. Solche Federelemente, in der Fachsprache auch "Spannklemmen" genannt, weisen in der Regel eine in Draufsicht W- oder ω-artige Form auf und wirken mit den freien Enden ihrer äußeren Niederhaltearme auf den Fuß der zu befestigenden Schiene, wogegen das zum Verspannen des Federelements vorgesehene Spannmittel gegen ihre Mittelschlaufe wirkt. Eine besonders einfache Montage ergibt sich hier dann, wenn die Unterlegabschnitte des durch einen elastisch verformbaren Verbindungsabschnitt des Halteteils miteinander verbunden sind.By the fact that the holding part has at least one shim section which can be pushed under an assigned section of the spring element during assembly, the shim section being arranged under the spring element after assembly, i.e. for example between the spring element and the surface on which the spring element is supported, this can Holding part are also set in a vertical direction with respect to the spring element, without the need for additional fasteners. Since the holding part has two underlay sections, of which one underlay section is assigned to one section of the spring element and the other underlay section to another section of the spring element, the generally symmetrical shape of spring elements used in fastening systems of the type in question here can be used to use. Such spring elements, also known as "tension clamps" in technical jargon usually have a W- or ω-like shape in plan view and act with the free ends of their outer hold-down arms on the foot of the rail to be fastened, whereas the tensioning means provided for tensioning the spring element acts against its middle loop. A particularly simple assembly results here when the support sections are connected to one another by an elastically deformable connecting section of the holding part.

Sowohl das Halteteil als auch die Abdeckkappe können kostengünstig aus einem Kunststoff hergestellt sein. Als Kunststoff für die Abdeckkappe eignen sich insbesondere alle Werkstoffe mit ausreichender Steifigkeit und Widerstandsfähigkeit, wobei hier insbesondere faserverstärkte Kunststoffe in Frage kommen, die bei hoher Formsteifigkeit minimierte Wandstärken erlauben. Da das Halteteil selbst keinen besonderen Belastungen ausgesetzt ist, sondern im Wesentlichen als Positionier- und Abdichthilfe für die Abdeckkappe dient, kann das Halteteil dagegen aus weniger hochwertigen Kunststoffen hergestellt sein. Der Kunststoff des Halteteils kann beispielsweise so ausgelegt sein, dass das Halteteil einerseits eine für seine Primärfunktion "Positionierhilfe" für die Abdeckkappe ausreichende Mindestformsteifigkeit, andererseits aber auch eine gewisse Flexibilität aufweist, um seine Montage zu erleichtern.Both the holding part and the cover cap can be made from a plastic at low cost. All materials with sufficient rigidity and resilience are particularly suitable as the plastic for the covering cap, with fiber-reinforced plastics in particular being suitable here, which permit minimized wall thicknesses with high dimensional stability. Since the holding part itself is not subjected to any particular stresses, but essentially serves as a positioning and sealing aid for the covering cap, the holding part can be made from lower-quality plastics. The plastic of the holding part can be designed, for example, so that the holding part has sufficient minimum dimensional stability for its primary function "positioning aid" for the covering cap, but also has a certain flexibility to facilitate its assembly.

Material- oder Gewichtseinsparungen können dabei insbesondere durch eine geeignete Formgebung der Abdeckkappe erzielt werden. So kann die Abdeckkappe kuppel-, gewölbe- oder spitzdachförmig ausgebildet werden. Um eine optimierte Formsteifigkeit bei minimierten Wandstärken zu erreichen, kann die Haltekappe im Bereich der von ihr umgrenzten Ausnehmung mit mindestens einer Verstärkungsrippe versehen sein. Solche Rippen können wahlweise an der der Ausnehmung selbst zugeordneten Innenseite oder an der Außenseite der Abdeckkappe vorgesehen sein.Material or weight savings can be achieved in particular by a suitable shape of the cover cap. The covering cap can be designed in the shape of a dome, a vault or a pointed roof. In order to achieve optimized dimensional stability with minimized wall thicknesses, the retaining cap can be provided with at least one reinforcing rib in the region of the recess it delimits. Such ribs can optionally be provided on the inner side assigned to the recess itself or on the outer side of the covering cap.

Ein erfindungsgemäßer Befestigungspunkt kann eine an dem Untergrund zu fixierende Führungsplatte umfassen, an der die Schiene seitlich geführt ist und auf der sowohl das Halteteil als auch das Federelement sitzen.A fastening point according to the invention can comprise a guide plate to be fixed to the ground, on which the rail is guided laterally and on which both the holding part and the spring element are seated.

Die in einem erfindungsgemäßen Befestigungspunkt befestigte Schiene kann in an sich bekannter Weise einen Schienensteg besitzen, an dem seitlich ein Dämpfungselement zur Reduzierung von Körperschallemissionen befestigt ist, wobei in das Dämpfungselement eine Ausnehmung eingeformt ist, in die die über das Federelement gestülpte Abdeckkappe greift. Die lagegenaue Positionierung des Abdeckelements in der Ausnehmung des Dämpfungselements kann dabei dadurch vereinfacht werden, dass das Halteteil ein Formelement besitzt, welches formschlüssig in eine korrespondierend geformte Aufnahme des Dämpfungselements greift.The rail fastened in a fastening point according to the invention can have a rail web in a manner known per se, to which a damping element for reducing structure-borne noise emissions is fastened laterally, a recess being formed in the damping element, into which the cover cap placed over the spring element engages. The exact positioning of the cover element in the recess of the damping element can be simplified in that the holding part has a shaped element which positively engages in a correspondingly shaped receptacle of the damping element.

Aus den erläuterten Gründen ist ein erfindungsgemäßer Befestigungspunkt besonders geeignet, in eine in flüssiger oder rieselfähiger Form angefüllte Füllmasse eingegossen zu werden. Die erfindungsgemäß auf dem Halteteil angeordnete und positionierte Abdeckkappe schützt dabei mindestens das Federelement sicher gegen einen Kontakt mit der Füllmasse. Selbstverständlich können die Abdeckkappe und das Halteteil dabei derart ausgebildet sein, dass sie nicht nur das Federelement, sondern auch andere funktionswesentliche Bauteile des Befestigungssystems gegenüber der Füllmasse abschirmen.For the reasons explained, a fastening point according to the invention is particularly suitable for being poured into a filling compound filled in liquid or free-flowing form. The covering cap arranged and positioned according to the invention on the holding part protects at least the spring element securely against contact with the filling compound. Of course, the cap and the holding part be designed in such a way that they shield not only the spring element, but also other functionally essential components of the fastening system from the filling compound.

Die Einrichtung 1 zum Abdecken eines Befestigungssystems B für einen Befestigungspunkt einer Schiene eine Abdeckkappe 2 und ein Halteteil 3.The device 1 for covering a fastening system B for a fastening point of a rail has a cover cap 2 and a holding part 3.

Die aus einem widerstandsfähigen, formsteifen Kunststoff hergestellte Abdeckkappe 2 ist nach Art einer im Querschnitt glockenförmigen Haube geformt und umgrenzt eine Ausnehmung 4.The covering cap 2 made of a resistant, dimensionally stable plastic is shaped like a hood with a bell-shaped cross-section and encloses a recess 4.

An der Innenseite der Ausnehmung 4 sind im Dachbereich der Abdeckkappe 2 sichelförmige Verstärkungsrippen 5 ausgeformt. Die Formen der Abdeckkappe 2 und der Verstärkungsrippen 5 sind dabei so aufeinander abgestimmt, dass bei maximaler Formsteifigkeit ein maximal großer freier Raum im Bereich der Ausnehmung 4 zur Aufnahme eines Federelements F des Befestigungssystems B vorhanden ist.Crescent-shaped reinforcing ribs 5 are formed on the inside of the recess 4 in the roof area of the cover cap 2 . The shapes of the cover cap 2 and the reinforcing ribs 5 are matched to one another in such a way that with maximum dimensional stability there is maximum free space in the area of the recess 4 for receiving a spring element F of the fastening system B.

Die eine Längskante L1 der Abdeckkappe 2 ist dem Schienenfuß SF der im Befestigungspunkt befestigten Schiene S zugeordnet. Im Eckbereich zwischen dieser Längskante L1 und den Stirnseiten 6,7 der Abdeckkappe 2 ist an jede der stirnseitigen Außenflächen der Stirnseiten 6,7 jeweils ein erstes Formelement 8 in Form eines schuhförmigen, flach auslaufenden Vorsprungs angeformt.One longitudinal edge L1 of the cap 2 is assigned to the rail foot SF of the rail S fastened at the fastening point. In the corner area between this longitudinal edge L1 and the end faces 6,7 of the cap 2, a first shaped element 8 in the form of a shoe-shaped, flat tapering projection is formed on each of the end-face outer surfaces of the end faces 6,7.

An der zur ersten Längskante L1 gegenüberliegenden Längskante L2 der Abdeckkappe 2 sind zwei weitere Formelemente 9,10 in Form von Rastvorsprüngen ausgebildet.On the opposite to the first longitudinal edge L1 longitudinal edge L2 of the cap 2, two further shaped elements 9,10 are formed in the form of locking projections.

Das anders als die Abdeckkappe 2 aus einem kostengünstigeren Kunststoff, wie einem PP- oder HDPE-Kunststoff, geformte Halteteil 3 weist in Draufsicht die Grundform eines "U" auf, dessen Schenkel durch zwei Unterlegabschnitte 11,12 und dessen Basis durch einen schmalen stegförmigen Verbindungsabschnitt 13 gebildet ist, der die Unterlegabschnitte 11,12 an ihrer der Längskante L2 der Abdeckkappe 2 zugeordneten Seite miteinander verbindet.The holding part 3, which is shaped differently than the cover cap 2 from a cheaper plastic, such as a PP or HDPE plastic, has the basic shape of a "U" in plan view, the legs of which have two underlay sections 11,12 and the base of a narrow web-like connecting section 13 is formed, which connects the underlay sections 11, 12 to one another on their side associated with the longitudinal edge L2 of the covering cap 2.

Der Verbindungsabschnitt 13 des Halteteils 3 ist dabei unter Berücksichtigung der Flexibilität des Kunststoffs, aus dem das Halteteil 3 besteht, so schmal ausgebildet, dass das Halteteil 3 trotz seiner grundsätzlichen Formsteifigkeit im Bereich des Verbindungsabschnitts 13 elastisch verformbar ist.The connecting section 13 of the holding part 3 is designed so narrow, taking into account the flexibility of the plastic from which the holding part 3 is made, that the holding part 3 is elastically deformable in the region of the connecting section 13 despite its basic dimensional stability.

Die Unterlegabschnitte 11,12 sind im Bereich der Seite, an der sie über den Verbindungsabschnitt 13 miteinander verbunden sind, nach oben abgekantet und weisen jeweils eine Rastöffnung 14,15 auf, die korrespondierend zu den als Rastvorsprünge dienenden Formelementen 9,10 an der Längskante L2 der Abdeckkappe 2 ausgebildet sind.The underlay sections 11,12 are bent upwards in the area of the side on which they are connected to one another via the connecting section 13 and each have a latching opening 14,15, which corresponds to the shaped elements 9,10 serving as latching projections on the longitudinal edge L2 the cap 2 are formed.

Der abgekantete Bereich der Unterlegabschnitte 11,12 geht in einen ebenen Zentralbereich der Unterlegabschnitte 11,12 über.The folded area of the underlay sections 11,12 merges into a flat central area of the underlay sections 11,12.

An dessen der Abdeckkappe 2 zugeordneten Oberseite ist jeweils ein als Anschlag für die lagegenaue Positionierung der Abdeckkappe 2 insbesondere in Bezug auf das jeweilige Federelement F des Befestigungssystems B dienendes, nach Art von schmalen Vorsprüngen ausgebildetes Formelement 16,17 angeformt. Die Formelemente 16,17 sind dabei an ihren einander zugeordneten Schmalseiten 18,19 jeweils nach Art von Stützen angeschrägt, um trotz ihrer Schmalheit eine optimale Stützwirkung zu haben. Auf diese Weise dienen die Formelemente 16,17 zum Zentrieren der Abdeckkappe 2 auf dem Halteteil 3 und können auch bei unvorhergesehenen hohen Kräften ein unbeabsichtigtes Verschieben der auf das Halteteil 3 aufgesetzten Abdeckkappe 2 sicher verhindern.On its upper side, which is assigned to the covering cap 2, there is a stop for the precise positioning of the covering cap 2, in particular in relation to the respective spring element F of the fastening system B serving, formed in the manner of narrow projections formed element 16,17. The shaped elements 16,17 are beveled on their associated narrow sides 18,19 in the manner of supports in order to have an optimal support effect despite their narrowness. In this way, the shaped elements 16, 17 serve to center the cap 2 on the holding part 3 and can also reliably prevent unintentional displacement of the cap 2 placed on the holding part 3 even in the event of unforeseen high forces.

Im Bereich ihrer der Längskante L1 der Abdeckkappe 2 zugeordneten Seite sind die Unterlegabschnitte 11,12 ebenfalls abgekantet, wobei die Abkantung hier im Querschnitt L-förmig ausgebildet ist, so dass der Endabschnitt der Abkantung im Wesentlichen parallel zum ebenen Zentralbereich der Unterlegabschnitte 11,12 ausgerichtet ist. An ihren der Längskante L1 der Abdeckkappe 2 und der Schiene S zugeordneten Kanten tragen die Unterlegabschnitte 11,12 jeweils ein Formelement 20,21 in Form eines zungenartig vorstehenden Vorsprungs.In the area of their side assigned to the longitudinal edge L1 of the cover cap 2, the underlay sections 11,12 are also beveled, the bevel being L-shaped in cross section here, so that the end section of the bevel is aligned essentially parallel to the flat central area of the underlay sections 11,12 is. On their edges associated with the longitudinal edge L1 of the cover cap 2 and the rail S, the underlay sections 11, 12 each carry a shaped element 20, 21 in the form of a tongue-like projection.

Die Stirnseiten 6,7 der Abdeckkappe 2 weisen an ihren unteren, dem Halteteil 3 zugeordneten Randbereich jeweils einen Abschnitt 22,23 auf, der derart geformt ist, dass er bei auf dem Halteteil 3 aufgesetzter Abdeckkappe 2 formschlüssig in dem durch die abgekanteten Bereiche und den Zentralbereich der Unterlegabschnitte 11,12 jeweils begrenzten Bereich sitzt. Die umlaufenden, die Öffnung der Ausnehmung 4 umgrenzenden Randkanten der Abdeckkappe 2 liegen bei fertig montierter Einrichtung 1 dicht an den ihnen zugeordneten Oberflächen des Halteteils 3.The end faces 6,7 of the cover cap 2 each have a section 22,23 on their lower edge region assigned to the holding part 3, which is shaped in such a way that when the cover cap 2 is placed on the holding part 3, it forms a positive fit in the area defined by the bent areas and the Central area of the underlay sections 11,12 each sits in a limited area. The circumferential, the opening of the recess 4 When the device 1 is fully assembled, the peripheral edges of the covering cap 2 lie close to the surfaces of the holding part 3 assigned to them.

Das Befestigungssystem B zur Befestigung der nach Art einer Rillenschiene geformten Schiene S für eine hier nicht gezeigte Straßenbahn ist in Bezug auf die Schiene S spiegelsymmetrisch aufgebaut und umfasst an jeder Längsseite LS1,LS2 der Schiene S jeweils ein nach Art einer konventionellen Spannklemme ausgebildetes Federelement F, ein durch eine konventionelle Schwellenschraube gebildetes Spannelement E, und eine nach Art einer konventionellen Winkelführungsplatte ausgebildete Führungsplatte P.The fastening system B for fastening the rail S, which is shaped like a grooved rail, for a tram (not shown here) is designed mirror-symmetrically in relation to the rail S and comprises a spring element F designed in the manner of a conventional tension clamp on each longitudinal side LS1, LS2 of the rail S. a clamping element E formed by a conventional sleeper screw, and a guide plate P designed in the manner of a conventional angled guide plate.

Die genannten Bauteile des Befestigungssystems B sind auf einem aus Kunststoff bestehenden Auflageprofil UP montiert, die quer zur Schiene S ausgerichtet und zwischen der Schiene S und dem hier beispielsweise durch eine Beton-Schwelle gebildeten Untergrund U angeordnet ist.The named components of the fastening system B are mounted on a plastic support profile UP, which is aligned transversely to the rail S and is arranged between the rail S and the substrate U formed here, for example, by a concrete sleeper.

Das Auflageprofil UP weist an seinen seitlichen Enden jeweils eine sich parallel zur Schiene S erstreckende Schulter T1,T2 auf. Die Schultern T1,T2 begrenzen zwischen sich eine Aufstandfläche AF, auf der die Schiene S über einer elastischen Zwischenplatte ZW steht. Dabei ist zwischen den Schultern T1,T2 und der Aufstandfläche AF jeweils eine Rille in die Oberseite des Auflageprofils UP eingeformt.The support profile UP has a shoulder T1, T2 extending parallel to the rail S at each of its lateral ends. The shoulders T1, T2 delimit a contact area AF between them, on which the rail S stands over an elastic intermediate plate ZW. A groove is formed in the upper side of the support profile UP between the shoulders T1, T2 and the contact area AF.

In der jeweiligen Rille sitzt formschlüssig der Winkelabschnitt der jeweiligen Führungsplatte P, die in an sich bekannter Weise einerseits an der zugeordneten Schulter T1 bzw. T2 abgestützt ist und andererseits mit ihrer der Schiene S zugeordneten Anlagefläche eine seitliche Führung für den Fuß SF der Schiene S bildet. Auf der Oberseite der Führungsplatten P sitzt jeweils ein Federelement F, das mit seinen freien Federarmen auf die ihm zugeordnete Oberseite des Schienenfußes SF wirkt.The angle section of the respective guide plate P, which is supported in a manner known per se on the one hand on the assigned shoulder T1 or T2 and on the other hand forms a lateral guide for the foot SF of the rail S with its contact surface assigned to the rail S, has a positive fit in the respective groove . On the upper side of the guide plates P there is a spring element F, which acts with its free spring arms on the upper side of the rail foot SF assigned to it.

Die Federelemente F sind jeweils durch eines der Spannelemente E gegen den Untergrund U verspannt. Dazu sind die Spannelemente E durch die Mittelschlaufe des jeweils zugeordneten Federelements F sowie die zugeordneten Durchgangsöffnungen der jeweiligen Führungsplatte P und das Auflageprofil UP in einen in den Untergrund U eingelassenen Dübel D geschraubt. Weitere Details des Aufbaus und der Montage des Befestigungssystems B sind in der Broschüre "System DFF 300 UTS", Stand 02/2015, veröffentlicht von der Vossloh Fastening Systems GmbH, Werdohl, Deutschland, erläutert. Die konventionell als Rillenschiene ausgebildete Schiene S umfasst neben dem Schienenfuß SF einen darauf stehenden Schienensteg ST, an dessen Seiten jeweils ein Dämpfungselement DE angeordnet ist. Von der dem jeweiligen Federelement F zugeordneten Seite her ist in die Dämpfungselemente DE im Bereich des Befestigungssystems B jeweils eine zum Schienenfuß SF und zum jeweiligen Federelement F hin offene Ausnehmung 24,25 eingeformt.The spring elements F are each braced against the substrate U by one of the tensioning elements E. For this purpose, the tensioning elements E are screwed into a dowel D embedded in the substructure U through the middle loop of the respectively assigned spring element F and the assigned through-openings of the respective guide plate P and the support profile UP. Further details of the structure and assembly of the fastening system B are explained in the brochure "System DFF 300 UTS", as of 02/2015, published by Vossloh Fastening Systems GmbH, Werdohl, Germany. The rail S, which is conventionally designed as a grooved rail, comprises, in addition to the rail foot SF, a rail web ST standing on it, on each side of which a damping element DE is arranged. From the side associated with the respective spring element F, the damping elements DE in the region of the fastening system B are each connected to the rail foot SF and formed towards the respective spring element F open recess 24,25.

Nachdem das Befestigungssystem B in konventioneller Weise montiert worden ist, wird an jeder Längsseite LS1,LS2 der Schiene jeweils eine Einrichtung 1 montiert. Dazu werden die Unterlegabschnitte 11,12 des jeweiligen Halteteils 3 durch Verbiegen im Bereich des Verbindungsabschnitts 13 so auseinander bewegt, dass sie von der jeweiligen Schulter T1,T2 des Auflageprofils UP herkommend an den Haltearmen des jeweiligen Federelements F vorbei und dann aus seitlicher Richtung unter den jeweiligen Haltearm des Federelements F geschoben werden können, bis der Verbindungsabschnitt 13 wieder gerade ausgerichtet ist und die Unterlegabschnitte 11,12 unter dem jeweiligen Haltearm sitzen.After the fastening system B has been mounted in a conventional manner, a device 1 is mounted on each longitudinal side LS1, LS2 of the rail. For this purpose, the underlay sections 11, 12 of the respective holding part 3 are moved apart by bending in the area of the connecting section 13 so that they come from the respective shoulder T1, T2 of the support profile UP past the holding arms of the respective spring element F and then from the side under the respective holding arm of the spring element F can be pushed until the connecting section 13 is aligned straight again and the underlay sections 11,12 sit under the respective holding arm.

Anschließend wird die Abdeckkappe 2 auf das Halteteil 3 gesetzt und soweit auf das Halteteil 3 gedrückt, bis die Formelemente 9,10 in die Rastöffnungen 14,15 einrasten. Der exakte Sitz der Abdeckkappe 2 in Bezug auf das Federelement F wird dabei durch die Formelemente 16,17 gewährleistet.The cap 2 is then placed on the holding part 3 and pressed onto the holding part 3 until the shaped elements 9,10 snap into the latching openings 14,15. The exact fit of the cap 2 in relation to the spring element F is ensured by the shaped elements 16,17.

Nun werden die Abdeckkappe 2 und das Halteteil 3 gemeinsam in Richtung der Schiene S verschoben, bis die Formelemente 8 unter das zugeordnete Dämpfungselement DE greifen und die jeweilige Einrichtung 1 ihre fertige Montageposition erreicht hat. Gleichzeitig liegen die Formelemente 20,21 dicht an den die Ausnehmung 24 der Dämpfungselemente (DE) seitlich begrenzenden Flächen an, so dass auch hier eine Barriere gegen das Eintreten von Füllmaterial oder Feuchtigkeit gebildet ist.Now the cover cap 2 and the holding part 3 are moved together in the direction of the rail S until the shaped elements 8 engage under the associated damping element DE and the respective device 1 has reached its finished assembly position. At the same time, the shaped elements 20, 21 lie tightly against the surfaces laterally delimiting the recess 24 of the damping elements (DE), so that here, too, a barrier is formed against the ingress of filling material or moisture.

Daraufhin wird das Befestigungssystem B in eine Füllmasse M, bei der es sich beispielsweise um fließfähig ausgebrachten Beton handelt, eingebettet und die Füllmasse M zusätzlich durch eine Deckschicht DS, bei der es sich beispielsweise um eine im Straßenbau übliche Teerdecke handelt, abgedeckt. Die Einrichtung 1 schirmt dabei die funktionskritischen Bauteile "Federelemente F", "Führungsplatten P" und "Spannelemente E" des Befestigungssystems B gegenüber der Füllmasse M ab.The fastening system B is then embedded in a filling compound M, which is, for example, poured concrete that is capable of flowing, and the filling compound M is additionally covered by a top layer DS, which is, for example, a tar covering that is customary in road construction. The device 1 shields the function-critical components “spring elements F”, “guide plates P” and “tensioning elements E” of the fastening system B from the filling compound M.
