Abstract
Description
Die Erfindung betrifft ein vorgefertigtes Kammerfüllelement für Schienen, insbesondere für Straßenbahnen, zum Einfügen zwischen Schienenkopf und Schienenfuß in Schienenkammem, im wesentlichen bestehend aus einem Körper aus anorganischem Material und mit einem damit verbundenen Profil aus elastischem Isolierstoff zur Anlage am Schienenkopf sowie ein Verfahren zur Herstellung eines solchen Kammerfüllelementes.The invention relates to a prefabricated chamber filling element for rails, especially for trams, for insertion between the rail head and Rail foot in rail comb, consisting essentially of a Body of inorganic material and with a related profile made of elastic insulating material for installation on the rail head and a method for producing such a chamber filling element.
Seit über 70 Jahren wird versucht, Schienen für spurgeführte Fahrzeuge mit Kammerfüllkörpem zur Dämpfung des Lärmes der von den befahrenen Schienen, insbesondere den Schienenstegen ausgeht (US-A 1 771 078), zu bestücken. Vorgeschlagen wurde seinerzeit, derartige Kammerfüllkörper, gegebenenfalls durch Klammem mit ebensolchen Unterlegteilen für den Schienenfuß verbunden, durch Vergießen von Bitumen, Harz, Gummi und verschiedenen Beimischungen herzustellen.For over 70 years it is tried to use rails for track-guided vehicles Kammerfüllkörpem to dampen the noise of the traveled Rails, in particular the rail webs starting (US-A 1 771 078), too equip. At that time, such Kammerfüllkörper, if necessary, by clamps with just such underlay parts for the Rail foot connected by potting bitumen, resin, rubber and produce various admixtures.
Kammerfüllkörper sind auch in einer hauseigenen "Technische Mitteilung Nr.
7.4/11.92" der Anmelderin aus 1992 dargestellt.
Berichtet wird darin, daß für Straßenbahnen im städtischen Nahverkehr neben
der Vermeidung von Erschütterungen und Lärmentwicklung durch
entsprechenden elastischen vertikalen Aufbau der Gleislagerung, der
Wirtschaftlichkeit für die horizontale Lagerung, d.h. die Abstützung der
Pflasterung oder Wege zum Oberbau hin Rechnung zu tragen ist. Daher
werden traditionell auch Betonkammersteine unterschiedlicher Größe
eingesetzt oder die Schienenkammem mit Mörtel ausgegossen.Kammerfüllkörper are also shown in an in-house "Technical Notice No. 7.4 / 11.92" of the applicant from 1992.
It is reported that trams in urban transport in addition to the avoidance of vibration and noise due to appropriate elastic vertical structure of the track bearing, the economy of the horizontal storage, ie the support of the pavement or paths to the superstructure out is taken into account. Therefore, concrete chamber stones of different sizes are traditionally used or the rail combs poured with mortar.
In der deutschen Zeitschrift "Verkehrstechnik", Heft 1, 1933, Ullstein-Verlag, Berlin, ist in einem Aufsatz von Bohnenberger: "Neuer Weg zur Verminderung von Gleisunterhaltungskosten" ein Füllstein aus tonrohrartigem Material oder Füllbeton erwähnt, der unter Zwischenfügung einer bituminösen Angußmasse, die schienenfußseitig und schienenstegseitig auf dem aus anorganischen Material bestehenden Körper aufgebracht wird, in die Schienenkammer, das ist der Bereich zwischen Schienenkopf, Schienensteg und Schienenfuß, eingebracht wird. Dadurch bilde sich zwischen Schiene und Stein ein absolut wasserdichter und fester Verband. Der Einfachheit halber wird dabei nur eine in die beidseitigen Schienenkammem passende Form des Tonsteines verwendet und die restliche Kammer mit der bitumenartigen Angußmasse, gegebenenfalls mit Splitt aufgefüllt, aufgefüllt.In the German magazine "traffic engineering", number 1, 1933, Ullstein publishing house, Berlin, is in an essay by Bohnenberger: "New way to reduce of track maintenance costs "a filler made of a clay tube-like material or Filled concrete, with the interposition of a bituminous casting material, the rail side and rail side on the inorganic Material existing body is applied to the rail chamber, that is the area between the rail head, rail bridge and rail foot, is introduced. As a result, an absolute bond is formed between rail and stone waterproof and firm bandage. For simplicity, only one will in the bilateral rail combs suitable form of the claystone used and the remaining chamber with the bitumen-like sprue, if necessary filled with chippings, filled up.
Es ist auch eine stabilisierte Fugenverfüllung zwischen einer Straßendecke und einer Schiene von straßenbündigen Gleisen unter Verwendung von Abdeckplatten als Deckenschluß bekannt (DE-A 42 04 802), bei der der durch die Schienenkammer und die Abdeckplatte gebildete Hohlraum durch Einbringen einer sackartigen Hüllfolie ausgelegt und diese Hüllfolie zunächst mit Beton bis zur Schienenkopfunterkante ausgepreßt und letztlich mit einem Fugenverguß bis zur Oberkante der Schiene beziehungsweise Abdeckplatte ausgefüllt wird.It is also a stabilized joint filling between a road surface and a rail of street level tracks using Cover plates known as ceiling closure (DE-A 42 04 802), in which the by the rail chamber and the cover plate formed by cavity Introducing a bag-like wrapper designed and this wrapper first pressed with concrete to the rail head lower edge and ultimately with a Grouting up to the upper edge of the rail or cover plate is completed.
Mit der EP-B 0 180 118 ist vorgeschlagen worden, oberhalb des Schienenfußes und mit Abstand zum Schienensteg bis zum Schienenkopf reichend, zwischen zwei Verschalungen Material zu vergießen, welches aus lösungsmittelfreiem, elastisch aushärtendem Zweikomponentenmaterial auf Polyurethanbasis besteht, in die Tonkömer als billiger Füllstoff eingeschlossen sind. In der DE-A 37 11 190 sind auch bereits Formstücke aus diesem Material mit gleicher Positionierung von demselben Anmelder offenbart.With EP-B 0 180 118 has been proposed above the Rail foot and with distance to the rail bridge to the rail head reaching to shed material between two shuttering, which made solvent-free, elastically curing two-component material on Polyurethane base is included in the Tonkömer as a cheap filler are. In DE-A 37 11 190 are already shaped pieces of this material disclosed with the same positioning by the same applicant.
In den bisher zitierten Veröffentlichungen, mit Ausnahme der ersten, wird bauartbedingt im wesentlichen versucht eine Schalldämmung zu erzielen, bei Verwendung preiswerter Füllstoffe. Bei der Anwendung für Straßenbahngleise, insbesondere im Zusammenhang mit Rillenschienen, haben die Füllkörper auch die Funktion der Körperschalltrennung zu dem umgebenden Strauenbaumaterial und sollen als Basis für den Verguß der Schienen bis zur Schienenoberkante dienen, um eine Lücke zwischen dem der Schiene benachbarten Pflaster bis zur Schiene hin zu verschließen. Aus diesen Gründen ist auch das dazu verwendete Vergußmaterial sehr elastisch gestaltet, um die Entkopplung der Körperschallschwingungen zu gewährleisten.In the publications cited so far, with the exception of the first one, due to the design essentially attempts to achieve a sound insulation, at Use of inexpensive fillers. In the application for tram tracks, especially in connection with grooved rails, have the packing also the function of the structure-borne sound separation to the surrounding Straubaumbaumaterial and should serve as the basis for the casting of the rails to the Rail top serve to fill a gap between the rail Close adjacent pavement to the rail. From these Reasons is also the potting material used very elastic designed to decouple the structure-borne sound vibrations guarantee.
Zur Verbesserung der Schalldämpfung dienen heute in der Regel Gummivollprofile oder Kunststoffvollprofile als Kammersteine oder auch mit aus recyceltem Material gewonnenen Füllstoffen versehene Polyurethankörper. Mit der DE-A 40 04 208 wurde vorgeschlagen, Teile aus mit Polyurethan gebundenen Gummiteilen mit einer Shore-Härte D 80 herzustellen und speziell für Straßenbahnschienen zu verwenden. Aus dem Material können stangenartige Formteile hergestellt werden, die eine den Kammern des Straßenbahnschienenprofils angepaßte Form aufweisen, wobei die Formteile vorzugsweise als Stangen von ca. 500 mm Länge und mit Aussparungen für die mit der Schiene verbundenen Bauteile versehen sind. Die Formteile können auch mit Nut und Feder versehen sein, um sie miteinander formschlüssig zu koppeln. Der Kammerstein aus dem mehrkomponentigen Material auf Polyurethanbasis unter Beimischung von Gummi weist gute schwingungdämpfende Eigenschaften auf und kann zudem 100%-ig recycelt werden, ist jedoch gegenüber den Betonkammersteinen teuer.To improve the soundproofing serve today usually Rubber full profiles or plastic full profiles as chamber stones or with Polyurethane bodies provided with fillers obtained from recycled material. With DE-A 40 04 208 has been proposed parts with polyurethane To produce bonded rubber parts with a Shore hardness D 80 and specifically to use for tram rails. From the material can rod-like moldings are made, which is a the chambers of the Tram track profiles have adapted shape, wherein the moldings preferably as rods of about 500 mm in length and with recesses for the components connected to the rail are provided. The moldings can also be provided with tongue and groove to each other to couple positively. The chamber stone from the multi-component Polyurethane-based material with admixture of rubber has good vibration-damping properties and can also be 100% recycled are expensive, but compared to the Betonkammersteinen.
Mit der DE 199 13 029 A1 wurde letztlich vorgeschlagen, Betonkammersteine und Gummi oder Kunststoffwerkstoffe miteinander zu kombinieren, wobei der Kammerstein aus einem Körper oder Basisprofil aus Beton besteht, der zur Schienenkopfseite hin um ein Kopfprofil aus elastomerem Werkstoff ergänzt wurde, der seinerseits im Basisprofil fest verankert ist, wobei sich das Kopfprofil elastisch an den Schienenkopf anlegen kann. Zur Vermeidung eines Zerstörungseffektes am Schienenfuß wird dabei auf Bereiche des Schienenfußes und des Schienensteges eine Matte aus einer Kautschukmischung aufgebracht und ein Schierenfußprofil aus einem Gummiwerkstoff angeordnet, auf die der Betonkörper des Kammersteines gelagert werden kann. Der Kammerstein selbst wird nur in die Schienenkammer eingeklemmt, wobei die Elastizität der Schienenfußummantelung und der Matte im Schienenfußbereich und am Schienenkopf die Elastizität des Kopfprofiles ausgenutzt wird.With the DE 199 13 029 A1 was finally proposed concrete block stones and rubber or plastic materials to combine with each other, the Kammerstein consists of a body or base profile made of concrete, which belongs to the Rail head side added to a head profile made of elastomeric material which in turn is firmly anchored in the base profile, whereby the Can create head profile elastic to the rail head. To avoid a Destruction effect on the rail foot is thereby on areas of Rail foot and rail bridge a mat of one Applied rubber compound and a Schierenfußprofil from a Rubber material arranged on the concrete body of the Kammersteines can be stored. The Kammerstein itself is only in the Rail chamber clamped, the elasticity of the Rail foot covering and the mat in the rail foot area and on the Rail head, the elasticity of the head profile is exploited.
Nachteilig ist dabei die mehrteilige Fertigung und Montage der eigentlichen Schienenanordnung aus dem Fußprofil, der Matte und dem mit Kopfprofil werkseitig versehenen Betonkörper, der Aufwand für die Vormontage des Basisprofiles mit dem Kopfprofil und die gegenseitige Verankerung ist ebenfalls relativ hoch.The disadvantage here is the multi-part production and assembly of the actual Rail arrangement of the foot profile, the mat and the head profile Factory provided concrete body, the cost of pre-assembly of the Basic profiles with the head profile and the mutual anchoring is also quite high.
Ausgehend von dem Stand der Technik liegt der Erfindung das Problem zugrunde, leicht einzubauende, gegenüber dem Stand der Technik jedoch wesentlich preiswertere und einfacher herzustellende, isolierende Kammerfüllelemente vorzuschlagen.Based on the prior art, the invention is the problem underlying, easy to install, compared to the prior art, however much cheaper and easier to produce, insulating To propose chamber filling elements.
Das Problem wird erfindungsgemäß durch die in den Ansprüchen 1 und 9
angegebenen Merkmale gelöst. Weiterbildungen der Erfindung sind in den
Unteransprüchen erfaßt.The problem is inventively by the in
Die Lösung sieht bei einem gattungsgemäßen Kammerfüllelement vor, daß es einstückig ausgebildet ist und mit Ausnahme der dem Schienensteg zugewandten Seite mit einer Umhüllung aus elastischem Isolierstoff versehen ist.The solution provides for a generic Kammerfüllelement that it is integrally formed and with the exception of the rail web facing side provided with a sheath of elastic insulating material is.
Unter elastischem Isolierstoff wird ein Kunststoffmaterial verstanden, wie es bisher beim Stand der Technik auch schon für Kammerfüllelemente verwendet wird, also Polyolefine, verschiedene Arten von kautschukartigen Mischungen bis zu vemetzten Polyurethanschäumen, wobei Polyurethanmaterial gemäß der DE-A-40 04 208 bevorzugt wird. Der Isolierstoff bietet elektrische Isolation und ist wasserdicht. Under elastic insulating material is a plastic material understood as it previously used in the prior art already for Kammerfüllelemente Thus, polyolefins, various types of rubbery mixtures to crosslinked polyurethane foams, wherein polyurethane material according to DE-A-40 04 208 is preferred. The insulating material provides electrical insulation and is waterproof.
Ein solcher Kammerstein oder Kammerfüllelement erfüllt alle Anforderungen
an die Körperschalldämmung, ist jedoch preiswerter als reine
Kunststoffprodukte und wird daher in der Praxis aus wirtschaftlichen Gründen
diesen vorgezogen werden. Er bietet eine gewisse Körperschalldämpfung
gegenüber dem Schienenfuß und eine Körperschalldämmung gegenüber dem
Schienensteg; dies sind bekanntlich die Teile der Schiene, die die größte
Schallabstrahlung haben. Darüber hinaus kann der Nachteil reiner
Betonkammersteine vermieden werden, nämlich die fehlende
Streustromisolation, die schlechte Paßgenauigkeit in der Schienenkammer und
die fehlende Wasserabdichtung, welche auch zum Zerbröseln oder bei
Vereisung zum Zerreißen der Betonsteine führen kann.
Ein weiterer Vorteil ist die werkseitige Herstellung des Kammerfüllelementes,
welches in situ sofort eingebaut werden kann und durch benachbarte
Kammerfüllelemente zu Endlossträngen ergänzt werden kann. Ein solcher
Kammerstein kann jedoch auch mit herkömmlichen, insgesamt aus Kunststoff
bestehenden, Kammerfüllelementen kombiniert werden. Zur Kombination der
Längen aneinander bedarf es dann keiner endseitigen Umkleidung der
Kammerfüllelemente, sondern nur, wenn die Endseite freigelegt und der
Witterung ausgesetzt ist.Such a chamber stone or chamber filling element meets all requirements for structure-borne sound insulation, but is cheaper than pure plastic products and will therefore be preferred in practice for economic reasons. He offers a certain structure-borne sound damping compared to the rail and a structure-borne sound insulation against the rail web; These are known to be the parts of the rail that have the greatest sound radiation. In addition, the disadvantage of pure Betonkammersteine can be avoided, namely the lack of stray current isolation, the poor fit in the rail chamber and the lack of waterproofing, which can also lead to crumbling or icing to rupture of concrete blocks.
Another advantage is the factory production of Kammerfüllelementes, which can be installed immediately in situ and can be supplemented by adjacent Kammerfüllelemente to endless strands. However, such a chamber stone can also be combined with conventional, made of plastic, Kammerfüllelementen. To combine the lengths together, there is no need for any end-side casing of the chamber filling elements, but only when the end side has been exposed and exposed to the weather.
Der Körper des Kammerfüllelementes kann an der dem Schienensteg
zugewandten Seite einen Rücksprung aufweisen, wie dies für sich schon
bekannt ist, um dort Raum zu haben für die Anbringung von Verschraubungen,
Spurstangenköpfen und ähnliches.
Die dem Schienenkopf und dem Schienenfuß zugewandten Seiten der
Umhüllung des Körpers sind mit zu Schienenkopf und Schienenfuß
komplementären schrägen Flächen versehen, welche geeignet sind, in die
Schienenkammer eingeklemmt zu werden, so daß das gesamte
Kammerfüllelement ohne Verklebung in der Schienenkammer verbleibt. Dazu
wird die Umhüllung in einer Dicke von etwa 5 bis 25 mm, vorzugsweise jedoch
nur etwa 8 bis 12 mm Dicke, hergestellt. Diese Dicke reicht aus, um genügend
Elastizität für das Einklemmen zu erzeugen, andererseits aber eine
mechanischen Schädigung des Betonkörpers und damit auch einer künftigen
Undichtigkeit gegen Wasser vorzubeugen sowie eine elektrische Isolation zu
bewirken.The body of the Kammerfüllelementes may have on the rail web side facing a recess, as is already known in order to have room for the attachment of fittings, tie rod ends and the like.
The rail head and the rail foot facing sides of the enclosure of the body are provided with rail head and rail complementary oblique surfaces which are adapted to be clamped in the rail chamber, so that the entire Kammerfüllelement remains without sticking in the rail chamber. For this, the sheath is produced in a thickness of about 5 to 25 mm, but preferably only about 8 to 12 mm in thickness. This thickness is sufficient to produce sufficient elasticity for pinching, but on the other hand to prevent mechanical damage to the concrete body and thus a future water leakage and to cause electrical insulation.
Als Füllkörper aus anorganischem Material wird vorzugsweise Material benutzt aus einer Gruppe, umfassend Beton, gebundene Tonkörper, Bimsstein, Naturstein, Steinzeug oder ähnlichem, wobei Beton oder eine entsprechende Mörtelmischung bevorzugt wird. Dieser Beton oder die Mörtelmischung kann auch mit einem speziellen Bindemittel versehen sein, das wiederum die Elastizität des Betonkörpers erhöht, damit dieser bei Schwingungen oder sonstigem Angriff auf den Körper nicht zerstört beziehungsweise seine Lebensdauer erhöht wird. Solche Bindemittel sind zum Beispiel Polymere, welche in der Praxis auch schon für die Herstellung von Polymer-Betonschwellen Verwendung finden. Mit dem Bindemittel ist auch eine gute Verarbeitbarkeit des Betons oder Mörtels gegeben.As filler of inorganic material preferably material is used from a group comprising concrete, bound clay bodies, pumice, Natural stone, stoneware or the like, with concrete or a corresponding Mortar mixture is preferred. This concrete or the mortar mixture can also be provided with a special binder, which in turn the Increased elasticity of the concrete body, so that this vibration or other attack on the body not destroyed or his Life is increased. Such binders are, for example, polymers, which in practice already for the production of polymer concrete sleepers Find use. With the binder is also a good one Processability of the concrete or mortar given.
Als Herstellverfahren für ein derartiges Kammerfüllelement wird vorzugsweise vorgeschlagen, zunächst eine etwa u-förmige Rinne oder eine Wanne mit Abmessungen, die geeignet sind, das fertige Kammerfüllelement in eine Schienenkammer klemmend einzubringen, herzurichten und eine solche Rinne oder Wanne mit einem anorganischen Material auszufüllen bis zur Oberkante der Rinne. Wenn als anorganisches Material Beton oder Mörtel verwendet wird, läßt sich während des Herstellvorganges zum Beispiel gleichzeitig mit dem Auffüllen oder nach Auffüllen der Rinne in das organische Material ein Rücksprung einbringen, zum Beispiel durch Pressen oder Einwalzen. Wenn anstelle von derartigen Vergußmassen Natursteine oder fertige Körper verwendet werden, sollten diese zuvor mit einer entsprechenden Nut versehen sein. In diesem Fall sind die Steine oder Körper in das elastische Isolierstoffmaterial einzukleben oder ihrerseits einzuklemmen. Dazu bedarf es einer entsprechenden Paßform der Steine beziehungsweise der inneren Ausbildung der Rinne beziehungsweise der Wanne, um den Stein klemmend zu halten. As a manufacturing method for such a Kammerfüllelement is preferably proposed, first having an approximately U-shaped channel or a tub Dimensions that are suitable, the finished Kammerfüllelement in a Clamping rail chamber, prepare and such a channel or pan with an inorganic material to fill up to the top the gutter. When used as an inorganic material concrete or mortar is, during the manufacturing process, for example, at the same time filling or after filling the channel in the organic material Return, for example by pressing or rolling. If instead of such potting natural stones or finished body used, they should be provided with a corresponding groove before be. In this case, the stones or bodies are in the elastic Glue insulating material or pinch it in turn. This is needed a corresponding fit of the stones or the inner Formation of the gutter or the tub to clamp the stone to keep.
Alternativ kann ein Basiskörper aus anorganischem Material durch Aufbringen von Polyolefin-Material dreiseitig und / oder zusätzlich an den Endseiten der Körper z.B. durch Warmumformen und / oder Verkleben der Urnkleidung mit einer Hülle versehen werden. Als Kleber kann ein Zwei-Komponenten-Kleber als Kontaktkleber oder wärmeaktivierbarer Kleber dienen, der eine genügende Haftvermittlung zwischen anorganischen und organischen Stoffen bewirkt. Hier kann insbesondere der aus der Praxis bekannte Icosit®-Material (Marke der Firma Sika-Chemie GmbH, Stuttgart, DE) auf Polyurethanbasis Verwendung finden.Alternatively, a base body of inorganic material may be applied by application of polyolefin material on three sides and / or additionally on the end sides of Body e.g. by hot forming and / or gluing the Urnkleidung with be provided a sheath. As an adhesive can be a two-component adhesive Serve as a contact adhesive or heat-activatable adhesive, which is a sufficient Adhesion between inorganic and organic substances causes. Here In particular, the Icosit® material known from practice (trademark of Company Sika-Chemie GmbH, Stuttgart, DE) based on polyurethane use Find.
Das fertiggestellte Element kann dann als paßfertiges Kammerfüllelement zur Baustelle gebracht werden.The finished element can then as paßfertiges chamber filling for Construction site to be brought.
Die Erfindung soll an einer schematischen Zeichnung kurz erläutert werden.

geeignete Schiene mit Steg 1, Schienenfuß 3 und den Kopfteilen 2 , 4,
letzteres mit der Rille für den Spurkranz des Straßenbahnrades. Der Raum
zwischen Schienenkopf, Schienensteg und Schienenfuß bildet die
Schienenkammer oder Laschenkammer. Da der Schienenfuß meist breiter ist
als der Schienenkopf wird das Kammerfüllelement zur Vereinfachung des

Kammerfüllelement angeordnet, das eine Hülle 7 aus elastischem Isolierstoff,
hier polyurethangebundenem Gummi-Werkstoff, aufweist, in die ein
Betonkörper 5 eingegossen wurde. Der Betonkörper 5 enthält einen
Rücksprung 9 als Freiraum für das Anbringen von Laschen oder
Verschraubungen am Schienensteg, wie sie zum Beispiel für Spurstangen
üblich sind. Im rechten Teilbild ist ein derartiger Betonkörper 5' eines
Kammerfüllelementes 6' mit ebensolcher Hülle 7' dargestellt. Das
Kammerfüllelement stützt sich mit der Hüllenaußenseite am Schienenkopf an
der Berührungsfläche 13 und andererseits am Schienenfuß an der
Kontaktfläche 14 ab. Das Kammerfüllelement ist in diese Position durch
Einpressen geklemmt worden. In gleicher Weise ist im rechten Teilbild die
Kontaktfläche 13' am Schienenkopf zu sehen und die Kontaktfläche 14' am
Schienenfuß. Zwischen der Straßenoberfläche 11 und dem Pflaster 12 ist die
restliche verbleibende Fuge 10 beziehungsweise 10' mit einer Vergußmasse,
beispielsweise aus Polyurethan, aufgefüllt worden.
Die hier monolithisch dargestellte Hülle kann auch aus mehreren Teilen z.B.
durch Verschmelzen zusammengefügt worden sein.
Außerdem kann die Hülle auch so gestaltet sein, daß auch der Bereich der zu
