Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines die Schienen eines Gleises aufnehmenden Betonformkörpers, insbesondere eine Gleisschwelle oder Gleistragplatte für einen überfahrbaren, schienengleichen Bahnübergang, mit einer auf mindestens einer tragenden Außenfläche angebrachten elastischen Schicht aus einem Elastomer oder elastischen Kunststoff, wobei der Betonformkörper in einer Form hergestellt wird, die mit einer elastischen Dämm-Matte mindestens teilweise ausgelegt und anschließend der Beton eingefüllt wird, so daß nach dem Abbinden des Betons die Dämm-Matte mit dem Betonformkörper verbunden ist.The invention relates to a method for producing a Rails of a concrete body that holds the track, in particular a track sleeper or track support plate for one traversable, level railroad crossing, with one on attached at least one supporting outer surface elastic layer made of an elastomer or elastic Plastic, with the molded concrete body in a mold is produced with an elastic insulation mat at least partially laid out and then the concrete is filled in so that after the concrete has set, the insulation mat is connected to the concrete molding.
Bei dem Bau von festen Gleisfahrbahnen werden Gleistragplatten aus Beton verwendet. Diese Gleistragplatten erhalten zum Zweck der Körperschalldämmung eine Lagerung mit Gummi.When building solid track carriages, track slabs are used made of concrete. These track support plates get for the purpose the structure-borne sound insulation is stored with rubber.
Es ist bekannt, Fahrbahnplatten aus Beton auf ihrer Unterseite mit elastischen Schichten aus Polyurethan-Matten vollflächig zu bekleben.It is known to have concrete pavement slabs on their underside with elastic layers of polyurethane mats over the entire surface to stick on.
Aus der EP 00 16 869 A1 ist eine Fahrbahnplatte für einen schienengleichen Bahnübergang bekannt, die sich auf den Schwellen abstützt, wobei diese Abstützung nur an bestimmten einzelnen Berührungspunkten vorhanden ist. In diesen Berührungspunkten, die auf der Unterseite der Fahrbahnplatte sind, ist eine Beschichtung aus elastischem Werkstoff vorhanden. EP 00 16 869 A1 describes a carriageway slab for one known railroad crossing known on the Thresholds supported, this support only on certain individual points of contact is present. In these Points of contact on the underside of the pavement slab are a coating of elastic material available.
Diese Konstruktion bewirkt keine Körperschalldämmung für den schienengebundenen Verkehr. Die elastischen Stützkörper dienen zur elastischen Lagerung der Tragrippen der Fahrbahnplatte und zur Minderung der Übertragung von Stoßkräften der Fahrbahnplatten auf die Schiene.This construction does not provide structure-borne noise insulation for the rail transport. The elastic support bodies serve for the elastic mounting of the support ribs of the carriageway slab and to reduce the transmission of impact forces Roadway slabs on the rail.
Aus der DE-A-27 07 615 ist ein Verfahren zur Herstellung einer Schienenbefestigung, die aus einer einen Teil des Unterbaues bildenden Betonkonstruktion mit Höhlungen zur Aufnahme von Betonstützblöcken besteht, bekannt, bei dem während der Herstellung der Betonstützblöcke bereits in der Betonform Platten elastischen Materials zur Bildung der elastischen Schicht angebracht sind. Diese elastischen Materialplatten werden auf der nach innen gerichteten Fläche mit einer Schicht flüssigen, erhärtbaren Kunstharzes, insbesondere Epoxydharzes überzogen. Anschließend wird der Beton in die Form geschüttet, wobei die Kunstharzschicht noch flüssig ist. Die Verbindung zwischen der elastischen Materialplatte und dem aushärtenden Beton wird durch eine zusätzliche Haftvermittlung gestaltet. Dieses erhöht den technischen Aufwand des Verfahrens erheblich. Außerdem ist die Haftung nicht immer ausreichend.DE-A-27 07 615 describes a method for producing a Rail fastening consisting of a part of the substructure forming concrete structure with cavities for receiving Concrete support blocks are known, in which during the Production of the concrete support blocks already in the concrete form Sheets of elastic material to form the elastic Layer are attached. These elastic sheets of material be on the inward facing surface with a layer liquid, hardenable synthetic resin, in particular epoxy resin overdrawn. Then the concrete is poured into the mold, the resin layer is still liquid. The connection between the elastic material plate and the hardening Concrete is shaped by an additional adhesive agent. This increases the technical complexity of the process considerably. Furthermore, liability is not always sufficient.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, bei dem die auf die die Gleise aufnehmenden Betonformkörper angebrachte elastische Schicht eine gute Haftung zu der Betonoberfläche aufweist und das Herstellungsverfahren einen geringeren Aufwand erfordert.The invention has for its object a method of to create the type mentioned, in which the on the tracks receiving concrete molded body attached elastic layer has good adhesion to the concrete surface and that Manufacturing process requires less effort.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die elastische Dämm-Platte eine Verbundmatte ist, die aus einer Schicht gebundenem Gummigranulat mit einer offenporigen Struktur und einer einseitig aufvulkanisierten, wasserundurchlässigen, verschleißfesten Deckschicht besteht und daß die Verbundmatte in die Betonformkörperform so verlegt wird, daß die Deckschicht an der Formwand anliegt. The object is achieved in that the elastic insulation board is a composite mat that consists of a Layer of bound rubber granulate with an open-pore one Structure and a vulcanized on one side, waterproof, wear-resistant top layer and that the composite mat is laid in the concrete form is that the cover layer lies against the mold wall.
Die Verbundmatte wird bei der Herstellung des Betonformkörpers in die Form oder Verschalung so verlegt, daß die Deckschicht zur Formwand bzw. Verschalung hinzeigt. Dadurch tritt die freiliegende, offenporige Struktur der Gummigranulatschicht in Kontakt mit dem flüssigen Beton. Der Beton diffundiert in die Grenzschicht der eine Dämmschicht bildenden Gummigranulatschicht ein. Dieses ergibt eine Verklammerung zwischen Beton und Verbundmatte. Die Verbundmatte verbleibt nach dem Abbinden des Betons beim Entformen an dem hergestellten Betonformkörper. Die Haftung ist ausgezeichnet. Der Betonformkörper ist sicher elastisch lagerbar bzw. gelagert.The composite mat is used in the manufacture of the concrete molding laid in the form or formwork so that the top layer points to the form wall or formwork. This causes the exposed, open-pore structure of the rubber granulate layer in Contact with the liquid concrete. The concrete diffuses into the Boundary layer of the rubber granulate layer forming an insulation layer a. This results in a bracketing between concrete and composite mat. The composite mat remains after setting of the concrete during demolding on the concrete molding produced. The liability is excellent. The concrete molding is can be stored or stored elastically.
Eine Verschiebung der Dämmplatte gegenüber dem zu lagernden Betonformkörper kann nicht mehr vorkommen. Die ausreichende Fixierung der Dämm-Matte am Betonformkörper erleichtert Transport und Einbau dieses Formkörpers, weil ein Lösen oder Verschieben der Dämm-Platte nicht zu befürchten ist.A shift of the insulation board compared to the one to be stored Concrete moldings can no longer occur. The sufficient Fixing the insulation mat on the concrete body made easier Transport and installation of this molded article because of loosening or Moving the insulation board is not to be feared.
Das während der Abbindung des Betons in die offenporige Dämmschicht eintretende Wasser wird durch die eine höhere Dichte aufweisenden Zuschlagstoffe, wie z.B. Kies, Zement und Sand aus der offenporigen Schicht an die spätere Betonformkörperoberfläche gepresst.That during the setting of the concrete in the open-pore Water entering the insulation layer is increased by the higher Density aggregates, such as Gravel, cement and Sand from the open-pore layer to the later one Pressed concrete surface.
In vorteilhafter Ausgestaltung der Erfindung wird die Herstellung des Betonformkörpers als Fertigteil vorgenommen. Die Betonformkörper werden als Fertigteilsegmente außerhalb der Baustelle in einer Fabrikstätte hergestellt und an die Baustelle gebracht. Die Betonformkörper mit den angebundenen Dämmplatten können sofort verlegt werden. Sie sind zwangsläufig sofort elastisch gelagert. Die elastischen Dämm-Matten werden auch teilweise im Seitenbereich angebracht, so daß bei Gleistragplatten Stoßfugen nicht separat ausgekleidet werden müssen. In an advantageous embodiment of the invention Manufacture of the concrete body made as a finished part. The concrete moldings are used as precast segments outside the construction site in a factory and to the Brought construction site. The concrete moldings with the attached Insulation boards can be installed immediately. they are inevitably elastically stored immediately. The elastic insulation mats are also partially attached in the side area, so that butt joints are not lined separately for track supporting slabs Need to become.
Eine weitere vorteilhafte Ausgestaltung ist darin zu sehen, daß die Herstellung von Gleistragplatten direkt am Einsatzort des Fahrbahnbaus vorgenommen werden kann. Dabei dient die elastische Dämm-Matte als verlorene Schalung.Another advantageous embodiment can be seen in that the production of track slabs directly on site of road construction can be made. The serves elastic insulation mat as lost formwork.
