Abstract

The fastening has a bolt connection which consists of galvanized bolt or a galvanized steel threaded bolt (2) or nut (6). A wedge shaped safety washer (5) is provided as intermediate layer (4) between the base plate of the pillar (3) and nut or bolt head and the bolt connection is tightened with pre-stressing. An independent claim is included for construction for fastening of pillar.

Description

Technisches GebietTechnical area

Die Erfindung betrifft die Verankerung von Pfosten einer Lärmschutzwand, besonders neben einer Hochgeschwindigkeitsstrecke.The Invention relates to the anchoring of posts of a noise barrier, especially next to a high-speed line.

Stand der TechnikState of the art

Die Pfosten einer Lärmschutzwand werden in ein Fundament eingegossen oder auf diesem mittels Schraubverbindung befestigt. Auf einer Brücke werden sie z.B. an den Endkappen befestigt, indem Schrauben durch Platten am Fuß der Pfosten in einbetonierte Hülsen eingeschraubt werden. Die Schrauben für die Befestigung von Lärmschutzwänden bestehen aus Edelstahl, der nur geringfügig vorgespannt werden darf.The Pole of a noise barrier are cast in a foundation or on this by means of screw attached. Become on a bridge they e.g. attached to the end caps by pushing screws through plates at the foot of the Pole in cast-in sleeves be screwed. The screws for the attachment of noise barriers consist made of stainless steel, which is only slightly may be biased.

Die Verschraubungen aller bisher zur Schraubbefestigung von Lärmschutzwandpfosten verwendeten Schraubverbindungsmethoden lockern sich daher nach einiger Zeit durch Schwingungen, die durch die mit hoher Geschwindigkeit nahe daran vorbeifahrenden Züge ausgelöst werden.The Fittings of all previously used for screw mounting of noise protection wall posts Screw connection methods loosen up after some time by vibrations that are close by those at high speed passing trains triggered become.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es, eine lockerungssichere Verankerung von mit einem Fundament verschraubten Pfosten für eine Lärmschutzwand, vor allem neben Eisenbahnstrecken, zu gewährleisten.task The invention is to provide a loosely anchored anchoring of a foundation bolted post for a noise barrier, especially next to Railway lines, to ensure.

Darstellung der ErfindungPresentation of the invention

Die Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.The The object is specified by that in the characterizing part of claim 1 Characteristics solved.

Wesentliches Merkmal der Erfindung ist die Verwendung von sogenannten Keilsicherungsscheiben als Unterlegscheiben zwischen Mutter und Anschlagfläche bzw. Schraubenkopf und Anschlagfläche, in Verbindung mit verzinkten Stahlgewindestangen bzw. Schrauben anstatt der bislang verwendeten Edelstahlschrauben, wodurch deutlich höhere Vorspannungen erreicht werden können und das Potential der Keilsicherungsscheiben voll ausgenützt werden kann.essential Feature of the invention is the use of so-called wedge lock washers as washers between nut and stop surface or Screw head and stop surface, in conjunction with galvanized steel threaded rods or screws instead of the previously used stainless steel screws, which clearly higher Bias can be achieved and fully exploiting the potential of the wedge lock washers can.

Solche Keilsicherungsscheiben wurden von der Fa. Nord-Lock® bereits 1983 eingeführt ( DE 83 02 613 U1 ).Such locking washers were introduced by the company. Nord-Lock ® 1983 ( DE 83 02 613 U1 ).

Die Keilsicherungsscheiben befinden sich zwischen dem zu befestigenden Material (Fußplatte des Lärmschutzpfostens) und der Mutter, bzw. dem Schraubenkopf.The Wedge washers are located between the to be fastened Material (foot plate of the Noise Post) and the nut, or the screw head.

Durch die Keilsicherungsscheiben in Verbindung mit verzinkten Schrauben anstatt Edelstahlschrauben wird bei vorgespannter Verschraubung die Lockerungsrate von Lärmschutzwänden gegenüber bisherigen Befestigungsmethoden wesentlich (um mehr als den Faktor 2) verbessert!By the wedge lock washers in conjunction with galvanized screws instead of stainless steel screws is in preloaded screw the Loosening rate of noise barriers compared to previous ones Attachment methods improved significantly (by more than a factor of 2)!

Die Figur zeigt eine Ausführung der Erfindung.The Figure shows an embodiment the invention.

In dem dargestellten Ausführungsbeispiel ist die Lärmschutzwand zwischen Stahlpfosten aufgeständert. Die Stahlpfosten weisen Fußplatten mit Öffnungen/Durchbrüchen/Bohrungen auf. Durch diese Öffnungen ragen von unten, aus der Endkappe kommend, in der sie mit ihrem einen Ende fest verankert sind, verzinkte Stahlgewindestangen nach oben. Auf die Enden, die aus den Öffnungen nach oben herausragen, sind Muttern mit Vorspannung aufgezogen, wobei sich zwischen Muttern und Fußplatte die Keilsicherungsscheiben befinden.In the illustrated embodiment is the noise barrier raised up between steel posts. The steel posts have foot plates with openings / openings / holes on. Through these openings sticking out from below, coming out of the end cap, where they are with their one end firmly anchored, galvanized steel threaded rods after above. On the ends that stick out of the openings, nuts are preloaded, taking between nuts and foot plate the wedge lock washers are located.
