Abstract

A construction for additional/subsequent fixture of a pillar or stanchion has borings extending through the entire thickness of the end-cap, threaded rods extending over the entire length of the boring and jutting out of top and bottom of the boring , counter-plates for extensive introduction of force into the concrete of the end caps. Nuts on the upper and lower ends of the threaded rods allow pulling of the footplates of the pillars and the counter plates up to the end caps, to provide the required pre-stressing.

Description

Technisches GebietTechnical area

Die Erfindung betrifft die nachträgliche Verankerung von Pfosten einer Lärmschutzwand auf einer Brücke.The Invention relates to the subsequent Anchoring posts of a noise barrier on a bridge.

Stand der TechnikState of the art

Die Pfosten einer Lärmschutzwand auf einer Brücke werden an den Endkappen einer Brücke befestigt, indem Schrauben durch Platten am Fuß der Pfosten in einbetonierte Hülsen eingeschraubt werden. Die Schrauben bestehen aus Edelstahl, der nur gering vorgespannt werden darf.The Pole of a noise barrier on a bridge be on the end caps of a bridge fastened by placing screws in concrete by means of plates at the foot of the posts sleeves be screwed. The screws are made of stainless steel, the may only be slightly biased.

Daher können bei einem Schwingen der Lärmschutzwand zeitweise Fugen zwischen Fußplatte und Beton klaffen, die zu einer Lockerung der Befestigung führen.Therefore can with a swing of the noise barrier at times joints between foot plate and concrete gape, which lead to a loosening of the attachment.

Manche Brücken, für die ursprünglich keine Lärmschutzwände vorgesehen waren, verfügen nicht über die einbetonierten Hülsen. Ein nachträgliches Bohren und Einbetonieren der Hülsen ist nicht fest genug.Some Bridges, for the originally No noise barriers provided were, dispose of no over the cast-in sleeves. A subsequent drilling and concreting the sleeves is not solid enough.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es, auch auf Brücken, die nicht über einbetonierte Hülsen verfügen, die sichere Verankerung von Pfosten für eine Lärmschutzwand zu gewährleisten.task The invention is also on bridges that do not have embedded in concrete sleeves dispose of that secure anchoring of posts for a noise barrier.

Darstellung der ErfindungPresentation of the invention

Die Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Wesentliches Merkmal der Erfindung ist eine Kon struktion mit Durchbohrung der Endkappe auf ganzer Dicke. Durch jede Bohrung hindurch erstreckt sich auf ganzer Länge eine Gewindestange aus verzinktem Stahl und diese ist an ihren aus der Endkappe herausragenden Teilen mit Muttern unter Vorspannung verschraubt, die das Klaffen der Fuge zwischen Fußplatte und Beton verhindert: am oberen Ende auf der Fußplatte des Pfostens, am unteren Ende auf einer Konterplatte auf der Unterseite der Endkappe. Die Konterplatte, die die Kräfte der Verschraubung auf großer Fläche in den Beton der Endkappe einleitet, ist auf der der Endkappe zugewandten Seite der Neigung der Unterseite der Endkappe angepaßt, so daß die Mutter auf der entgegengesetzten Seite der Konterplatte plan aufliegt.The The object is specified by that in the characterizing part of claim 1 Characteristics solved. essential Feature of the invention is a con struction with perforation of End cap on full thickness. Extends through each hole on the whole length a threaded rod made of galvanized steel and this is at her the end cap protruding parts with nuts under preload screwed, the gaping of the joint between foot plate and concrete prevented: at the upper end on the foot plate of the post, at the bottom End on a counter plate on the underside of the end cap. The Counter plate, the forces the screwing on large area initiating into the concrete of the end cap is on the end cap facing Side adapted to the inclination of the underside of the end cap, so that the nut on the opposite side of the counter plate rests flat.

Eine weitere Verbesserung im Schwingungs-/Lockerungsverhalten der Muttern erzielt man durch zusätzliche Verwendung von sogenannten Keilsicherungsscheiben (wie sie z.B. von der Fa. Nord-Lock angeboten werden) als Unterlegscheiben zwischen Mutter und Fußplatte bzw. Konterplatte.A further improvement in the oscillation / loosening behavior of the nuts one achieves by additional Use of so-called wedge lock washers (e.g. offered by the company Nord-Lock) as washers between Mother and foot plate or counter plate.

Die Figur zeigt schematisch im Querschnitt durch die Endkappe einer Brücke eine mögliche Ausführung der Erfindung.The Figure shows schematically in cross-section through the end cap of a bridge a possible execution the invention.
