Description

Vorrichtung zur Befestigung der Schienen auf Betonschwellen mittels in durchgehenden, sich verjüngenden Bohrungen der Schwelle geführter Befestigungsschraubenbolzen Die Erfindung betrifft eine Vorrichtung zur Befestigung der Schienen auf Betonschwellen. Es sind bereits Vorrichtungen bekannt, bei denen die Befestigungsbolzen in durchgehenden, sich verjüngenden Bohrungen der Schwelle geführt werden. Gemäß der Erfindung stützen sich Schaft und Kopf der Befestigungsschrauben gegen nachgiebige Zwischenlagen ab. Man erreicht hierdurch, daß die durch das Befahren der Schienen entstehenden Stöße sanft auf eine verhältnismäßig große Fläche übertragen und die Betonflächen sowie die Befestigungsschrauben geschont werden. Auch erfordert die Unterbringung der Befestigungsschrauben nur geringen Raum, so daß die Schwelle bedeutend weniger durch die Aussparungen geschwächt wird, als dies bei der Verwendung von Holzkissen oder Holzdübeln der Fall ist.Device for fastening the rails on concrete sleepers by means of fastening screw bolts guided in continuous, tapered bores in the threshold The invention relates to a device for fastening the rails on concrete sleepers. Devices are already known in which the fastening bolts in continuous, tapered bores of the threshold are performed. Support according to the invention The shaft and head of the fastening screws are opposed to flexible intermediate layers. This ensures that the shocks caused by driving on the rails gently transferred to a relatively large area and the concrete surfaces as well the fastening screws are spared. Also requires housing the Fastening screws only have a small space, so that the threshold is significantly less through The cutouts are weakened than is the case with the use of wooden pillows or Wooden dowels is the case.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Abb. z zeigt einen Querschnitt durch, die Schienenbefestigung auf einer Betonschwelle unter Verwendung von Hakenplatte, Klemmplatten und durchgehenden Befestigungsschraubenbolzen.Fig. Z shows a cross-section through the rail fastening a concrete sleeper using hook plate, clamping plates and through Mounting screw bolts.

Abb. 2 ist eine Ansicht von unten gegen die Schwelle und eine Befestigungsschraube.Figure 2 is a bottom view of the sleeper and a mounting screw.

Die Schiene a ist mittels der Klemmplatte c auf der Hakenplatte b gelagert. Auf der Betonschwelle d ist zweckmäßig unter Zwischenlage einer Isolierschicht e die Hakenplatte b aufgelegt. Die Schwelle d erhält durchgehende, sich verjüngende Bohrungen f, an die sich auf der unteren Schwellenseite Aussparungen g für die Schraubenköpfe anschließen. Die Befestigung erfolgt durch Schrauben h, deren Kopf als Hammerkopf ausgebildet sein kann. Die Schraube h ist von einer einteiligen oder mehrteiligenSchutzhülse i aus federnd nachgiebigemWerkstoff umumgeben. Die Schutzhülse oder auch Schraube und Schutzhülse sind entsprechend der Gestalt der durchgehenden Öffnung f sich verjüngend ausgebildet. Der Kopf der Schraube h stützt sich ebenfalls durch eine federnd nachgiebige Zwischenlage gegen die Unterseite der Betonschwelle ab.The rail a is by means of the clamping plate c on the hook plate b stored. It is advisable to place an insulating layer on the concrete sleeper d e the hook plate b is placed. The threshold d is given continuous, tapering Holes f, to which there are recesses g for the screw heads on the lower side of the sleeper connect. It is fastened with screws h, the head of which is a hammer head can be formed. The screw h is of a one-piece or multi-piece protective sleeve Surrounded by resilient, flexible material. The protective sleeve or screw and protective sleeve are tapered in accordance with the shape of the through opening f educated. The head of the screw h is also supported by a resilient one Liner against the underside of the concrete sleeper.

Durch die allseitig federnd nachgiebige Lagerung der Befestigungsschrauben h erreicht man eine sanfte Übertragung der Schienenstöße auf die Schwelle bei größter Lebensdauer der Schwelle und der Befestigungsschrauben.Due to the resilient mounting of the fastening screws on all sides h one achieves a smooth transfer of the rail joints to the sleeper at the greatest Lifetime of the threshold and the fastening screws.
