Abstract

An element for securing railway rails on a solid track comprises an anchor (16) with a cone (6) in its front region followed by a mixing centring head (7), and a bolt (16) whose surface is partially provided with a profile (5). This anchor (16) makes it possible to secure the railway rails in a reliable and direct manner by means of a hardenable mass.

Description

Beschreibung description
Befestigungselement zur Befestigung von Eisenbahnschienen auf einer festen FahrbahnFastening element for fastening railroad tracks to a solid carriageway
Die Erfindung betrifft ein Befestigungselement zur Befestigung von Eisenbahnschienen auf einer festen Fahrbahn, d. h. Schienenbefestigung für schotterlosen Oberbau mit Hilfe von einer aushärtbaren Masse.The invention relates to a fastening element for fastening railroad tracks on a solid carriageway, d. H. Rail fastening for ballastless superstructure with the help of a hardenable mass.
Aus der DE OS 30 14 569 ist ein Befestigungsanker zur spreizdruckfreien Be- festigung bekannt.From DE OS 30 14 569 a fastening anchor for fastening without expansion pressure is known.
Die Befestigung nach der bekannten Lösung erfolgt in der Weise, daß in ein mit Mörtelmasse verfülltes Bohrloch des Untergrunds ein Befestigungselement mit einem Verankerungsbereich eingesetzt wird. Im Mündungsbereich des Bohrlochs ist eine Zentrierhülse angebracht. Die Zentrierhülse weist am Umfang in Längsrichtung verlaufende Nuten auf, die beim Einsetzen des Befestigungselements in das Bohrloch ein Verdrängen der Mörtelmasse bewirkt.The fastening according to the known solution takes place in such a way that a fastening element with an anchoring area is inserted into a borehole of the subsurface filled with mortar compound. A centering sleeve is attached in the mouth area of the borehole. The centering sleeve has grooves running in the longitudinal direction on the circumference, which causes displacement of the mortar mass when the fastening element is inserted into the borehole.
Die Praxis zeigt, daß das bekannte System nur in einem eingeschränkten Be- reich eingesetzt werden kann. Beispielsweise kann dieses System bei den großen Betonplatten, in denen oft Spannungsrisse entstehen, die durch dasPractice shows that the known system can only be used in a restricted area. For example, this system in the large concrete slabs, in which stress cracks often occur, which are caused by the
Bohrloch verlaufen können, nicht verwendet werden. Durch die entstehenden Spannungsrisse ändert sich die Geometrie des Bohrlochs, die dazu führt, daß der Verbund zur Bohrlochwandung unterbrochen wird. In einem solchen Fall kann das Befestigungselement bei zunehmender Zugkraft aus dem Bohrloch herausgleiten. Ferner ist durch den geringen Durchmesser des Bolzens und verhältnismäßig großen Ringspalt ein Einsatz dieses Systems für die Befestigungen unter dynamischen Lasten ungeeignet.Drill hole can not be used. The resulting stress cracks change the geometry of the borehole, which means that the bond to the borehole wall is interrupted. In such a case, the fastening element can slide out of the borehole as the tensile force increases. Furthermore, due to the small diameter of the bolt and the relatively large annular gap, use of this system is unsuitable for fastenings under dynamic loads.
Ein weiteres System zur Befestigung von Eisenbahnschienen auf einer festen Fahrbahn ist in der DE-OS Nr. 24 53 713 dargestellt. Um die Eisenbahnschiene zu befestigen, ist hier ein Anker vorgeschlagen, der im wesentlichen drei Hauptabschnitte aufweist, das mit einem Gewinde versehene Ankeranschlußstück, einen Übergangsbereich, der einen Übergangskonus bildet, und einen Einsteckteil. Der Anker wird im Bohrloch mit Hilfe einer zerstörbaren Glaspa- trone gesetzt.Another system for fastening railroad tracks to a solid carriageway is shown in DE-OS No. 24 53 713. In order to fasten the railroad track, an anchor is proposed here which essentially has three main sections, the threaded anchor connection piece, a transition area which forms a transition cone, and an insertion part. The anchor is placed in the borehole with the help of a destructible glass cartridge.
Als nachteilig hat sich gezeigt, daß beim drehend-schlagenden Setzen des Ankers, insbesondere bei längeren Setzzeiten, die oft benötigt werden, um die Glassplitter mit den Patronenkomponenten zu vermengen, eine unvollständige Vermörtelung, insbesondere im Bohrlochmund, eintritt. Die unvollständigeIt has been shown to be disadvantageous that when the anchor is rotated and struck, in particular in the case of longer setting times, which are often required to mix the glass fragments with the cartridge components, incomplete mortaring occurs, particularly in the borehole mouth. The incomplete
Vermörtelung verursacht eine höhere Querkraftbeanspruchung des Ankers. Dadurch, daß der Anker mit einem Gewinde versehen ist, wird die Ankerstange geschwächt und eine Kerbwirkung tritt ein. Ferner ist das bekannte System durch die vielen Einzelteile, die beim Setzen zusammengeführt sein müssen, kosten- und montageaufwendig.Mortar causes a higher shear load on the anchor. Because the anchor is threaded, the anchor rod is weakened and a notch effect occurs. Furthermore, the known system is costly and assembly-intensive due to the many individual parts that have to be brought together during setting.
Dadurch, daß bei dem bekannten System nur eine dünne Isolierschicht eingesetzt wird, ist eine elastische Lagerung der Schienen nicht möglich. Die Aufgabe der Erfindung ist, ein Befestigungselement zur Befestigung vonBecause only a thin insulating layer is used in the known system, an elastic mounting of the rails is not possible. The object of the invention is a fastening element for fastening
Eisenbahnschienen auf einer festen Fahrbahn bereitzustellen, das einfach hergestellt werden kann, eine direkte Montage ermöglicht und eine dauerhafte elastische Lagerung gewährleistet.To provide railroad tracks on a solid track that is easy to manufacture, enables direct assembly and ensures permanent elastic storage.
Die Lösung dieser Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale erreicht.This object is achieved by the features specified in claim 1.
Durch den erfindungsgemäßen Anker, der im vorderen Bereich einen Konus aufweist, an den sich ein Misch-Zentriertkopf anschließt, und die Oberfläche des Bolzens bereichsweise mit einer Profilierung versehen ist, wird eine direkte und sichere Befestigung von Eisenbahnschienen auf einer festen Fahrbahn mit Hilfe von einer aushärtenden Masse ermöglicht. Durch den Misch-Zentrierkopf ist sichergestellt, daß der Bolzen im Bohrloch zentrisch fixiert und damit ein höherer elektrischer Widerstand gewährleistet wird. Durch die schräg verlau- fenden Rippen und Nuten am Misch-Zentrierkopf wird beim Einsatz einer Einschlagpatrone ein gutes, homogenes Vermischen der Komponente im Bohrloch erreicht, und somit eine notwendige Verzahnung mit der aushärtenden Masse, insbesondere im profilierten Bereich des Ankers, erzielt. Beim Auftritt von Rissen, die durch Zwängungen in der festen Fahrbahn entstehen, wird die Mörtel- schale auf dem Konus nachspreizen, und die Befestigung vor der Lockerung abgesichert.Through the anchor according to the invention, which has a cone in the front area, which is followed by a mixing centering head, and the surface of the bolt is provided with a profiling in some areas, a direct and secure fastening of railroad tracks on a solid carriageway is achieved with the aid of a curing mass allows. The mixing centering head ensures that the bolt is fixed centrally in the borehole, thus ensuring a higher electrical resistance. Due to the inclined ribs and grooves on the mixing centering head, a good, homogeneous mixing of the components in the borehole is achieved when using an impact cartridge, and thus a necessary interlocking with the hardening mass, especially in the profiled area of the anchor, is achieved. If cracks occur due to constraints in the solid carriageway, the mortar shell is spread out on the cone and the fastening secured against loosening.
