Description
Die Erfindung betrifft eine Vorrichtung zum Verankern von Pfosten von Sicherheitsabsperrungen, insbesondere Leitplankenanordnungen für Straßen, Wege u.dgl. mit den Bewehrungsstäben eines Fundamentes.The invention relates to a device for anchoring posts of Safety barriers, in particular guardrail arrangements for roads, Paths and the like with the reinforcement bars of a foundation.
Aus der EP-A-0112 804 ist eine Vorrichtung dieser Art zum Verankern von Pfosten von Sicherheitsabsperrungen bekannt geworden, umfassend ein einen Hohlraum aufweisendes Hohlprofilstück, das zwecks Einstecken eines Pfostens an wenigstens seinem oberen Ende offen ist und dessen im wesentlichen allseits geschlossener Hohlraumquerschnitt dem Querschnitt des eingesteckten Pfostens zwecks Halterung desselben entspricht, und das an seiner Außenseite wenigstens einen Verankerungsvorsprung mit mindestens einer Verankerungsöffnung aufweist. Dabei müssen die Verankerungsvorsprünge im Vergleich zu dem relativ kleinen zylindrischen Hohlraum für den Pfosten sehr groß sein, um dem Fundament oder Erdreich gegenüber für eine genügende Krafteinleitung und damit Stabilität für das Hohlprofilstück sicherzustellen. Für die Aufnahme von Leitplankenanordnungen für Straßen, bei denen sehr hohe Stoßkräfte aufgenommen werden müssen, sind diese Vorrichtungen insbesondere auch deshalb nicht geeignet, da sie nur senkrecht zu den Verankerungsvorsprüngen wirkende Kräfte aufnehmen können.From EP-A-0112 804 a device of this type for anchoring Posts of security barriers have become known, comprising a one Hollow section having a hollow profile piece for the purpose of inserting a post is open at least at its upper end and its essentially cavity cross section closed on all sides the cross section of the inserted Corresponds to the post for the purpose of holding it, and that on its outside at least one anchoring projection with at least one anchoring opening having. The anchoring projections must be compared to that relatively small cylindrical cavity for the post to be very large opposite the foundation or soil for sufficient force transmission and thus ensuring stability for the hollow profile piece. For receiving of guardrail arrangements for roads where very high impact forces These devices must be included in particular therefore not suitable as they are only perpendicular to the anchoring projections can absorb acting forces.
Leitplankenanordnungen, die auch als "Highway Guard" oder "Railing" bezeichnet werden, sind am Straßenrand installiert und dienen dazu, Fahrzeuge, die von der Fahrbahn abgekommen sind, zurückzuhalten sowie in ihrer Bewegungsbahn wieder auszurichten. Sie bestehen im wesentlichen aus Längsholmen, Pfosten und Verbindungselementen, wie beispielsweise Schrauben, zum Befestigen der Längsholme an den Pfosten. Die Längsholme sind aus geeigneten Flach- oder Profilstählen ausgebildet, die in einer Höhe über dem Erdboden angeordnet sind, die der Höhe des Schwerpunktes der am häufigsten vorkommenden Fahrzeuge entspricht. Die Pfosten bestehen im allgemeinen aus Stahlprofilteilen, die direkt in das Erdreich eingelassen sind. Jeder Pfosten ist über einen Betonsockel, eine Verankerungsplatte oder dgl. in Mauern oder anderen Konstruktionen am Rand der Straße, des Viadukts, der Brücke od.dgl., verankert und erfordert einen erheblichen Arbeitsaufwand, um nach einer Verformung oder Beschädigung ausgewechselt zu werden. Guardrail arrangements, also called "Highway Guard" or "Railing" are installed on the side of the road and are used to Retain vehicles that have strayed from the road as well as in align their trajectory again. They essentially consist of Longitudinal spars, posts and connecting elements, such as screws, for attaching the longitudinal bars to the posts. The longitudinal spars are out suitable flat or profile steels formed at a height above Soil are arranged the most often the height of the center of gravity occurring vehicles. The posts generally consist of Steel profile parts that are embedded directly in the ground. Everyone Post is in via a concrete base, an anchoring plate or the like Walls or other structures on the edge of the street, the viaduct, the Bridge or the like, anchored and requires a lot of work to to be replaced after deformation or damage.
Aus der DEPS 1 684 640 sind Halter mit Bajonettverbindung für Pfosten mit rohrförmigem Querschnitt bekannt, die durch einen geeigneten Stift gesichert sind. Diese Halter und das zugehörige Halterungs- und Blockiersystem eignen sich nur für Pfosten mit rundem rohrförmigen Querschnitt. Außerdem ist ihre Konstruktion zu kompliziert und weist zu enge Toleranzen auf, die die Funktion bei Oxydation oder Korrosion oder auch bei geringen Verformungen beeinträchtigen.From DEPS 1 684 640 are holders with bayonet connection for posts with tubular cross section known, secured by a suitable pin are. These holders and the associated mounting and locking system are suitable only for posts with a round tubular cross-section. Besides, hers is Construction too complicated and too close tolerances, which the Function in the event of oxidation or corrosion or even with minor deformations affect.
Im DE-GM 1 845 138 und in der US-A-3 225 501 sind Systeme offenbart, die eine Verriegelung zwischen Pfosten und Halter bewirken. In beiden Fällen ist jedoch der Nachteil gegeben, daß verschiedene mechanische Elemente benutzt werden, die mit einer gewissen Präzision zusammenzufügen sind. Bei geringfügigen Verformungen oder bei Korrosion ist eine zuverlässige Funktion nicht mehr gewährleistet.In DE-GM 1 845 138 and in US-A-3 225 501 systems are disclosed which lock the post and bracket. In both cases however, there is the disadvantage that different mechanical elements are used that have to be put together with a certain precision. At minor deformations or corrosion is a reliable function no longer guaranteed.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so weiterzubilden, daß sie auch hohe Stoßkräfte aufnehmen kann.The invention has for its object a device of the beginning mentioned type so that they also absorb high impact forces can.
Diese Aufgabe wird durch die Merkmale des Anspruches 1 gelöst. Die durch die Verankerungsöffnungen verlaufenden Bewehrungsstäbe des Fundamentes werden unmittelbar für die Stabilisierung und Krafteinleitung der auftretenden Kräfte einbezogen, während diejenigen Kräfte, welche quer zum Verlauf der Bewehrung des Fundamentes in dieses von dem Hohlprofil aus einzubringen sind, durch die Profilform des Hohlprofiles selbst aufgefangen werden. Die Verankerungsvorsprünge können dabei relativ klein gehalten werden, da sie über ihre Verankerungsöffnungen in die Bewehrung des Fundamentes einbezogen werden, so daß bei einer gegebenen Fundamentgröße ein vergleichsweise großer Hohlprofilraum für einen entsprechend großen und stabilien Profilpfosten geschaffen ist.This object is solved by the features of claim 1. The through the Reinforcing bars of the foundation running through the anchoring openings immediately for the stabilization and force application of the occurring Forces included, while those forces that are transverse to the course of the Reinforcement of the foundation in this from the hollow profile are caught by the profile shape of the hollow profile itself. The Anchoring projections can be kept relatively small because they included in the reinforcement of the foundation via their anchoring openings be, so that for a given foundation size a comparatively large Hollow profile space for a correspondingly large and stable profile post is created.
Der Hohlraumquerschnitt des Hohlprofilstücks entspricht unter Berücksichtigung eines gewissen Spiels demjenigen des Pfostens, der somit ohne übermäßige Kraftanstrengung von oben her in das Hohlprofilstück eingesteckt und aus diesem herausgezogen werden kann, auch dann, wenn er verbogen worden sein sollte, da das in allen Richtungen genügend stabil eingebettete Hohlprofilstück formstabil bleibt. Der Pfosten und der Hohlraumquerschnitt bzw. das Hohlprofilstück haben ein U-, T- oder Doppel-T-Profil. Die Bewehrungsstäbe des Fundamentes werden als Verankerungselement des Hohlprofiles einbezogen. Um Bewehrungsstäbe unterschiedlicher Durchmesser verwenden zu können, weist das Hohlprofilstück vorteilhafterweise wenigstens zwei Verankerungsöffnungen unterschiedlicher Öffnungsweite auf.The cavity cross section of the hollow profile piece corresponds, taking into account of a certain game that of the post, which is therefore without excessive force inserted into the hollow section from above and can be pulled out of it, even if it has been bent should be, since the embedded in all directions sufficiently stable Hollow profile piece remains dimensionally stable. The post and the cavity cross section or the hollow profile piece have a U, T or double T profile. The Reinforcement bars of the foundation are used as anchoring element of the hollow profile involved. To different reinforcement bars To be able to use diameter, the hollow profile piece advantageously has at least two anchoring openings of different opening widths on.
Zur Verbesserung der Verankerung kann das Hohlprofilstück eine strukturierte, vorzugsweise in Längsrichtung gerippte äußere Oberfläche aufweisen.To improve the anchoring, the hollow profile piece can have a structured, preferably have a longitudinally ribbed outer surface.
Um das Eindringen von Feuchtigkeit und damit Korrosion, die das Entfernen des eingesteckten Pfostens erschweren würde, zu verhindern, ist in Weiterbildung der Erfindung eine Dichtung vorgesehen, die am oberen Ende des Hohlprofilstücks zwecks Abdichtung gegenüber dem eingesteckten Pfosten anbringbar ist. Diese Dichtung kann eine mittels eines geeigneten Werkzeugs in den dem Spiel entsprechenden Spalt zwischen der den Hohlraum begrenzenden Innenwandfläche des Hohlprofilstücks und der Außenfläche des Pfostens einfüllbare Silikonmasse oder eine vorgefertigte Dichtung sein, die eine aus dem Hohlprofilstück herausragende, nach außen abstehende Lippe aufweist. Die Dichtung hat außerdem die Funktion, einen spielfreien Sitz des Pfostens im Hohlprofilstück zu gewährleisten.To prevent the ingress of moisture and therefore corrosion, the removal of the inserted post would be difficult to prevent Further development of the invention, a seal is provided at the upper end of Hollow section piece for sealing against the inserted post is attachable. This seal can be made using a suitable tool in the gap corresponding to the game between the delimiting the cavity Inner wall surface of the hollow profile piece and the outer surface of the post fillable silicone mass or a prefabricated seal, which is a the hollow profile piece has protruding, protruding lip. The The seal also has the function of ensuring that the post fits perfectly in the To ensure hollow profile piece.
Zum gleichen Zweck können Vorsprünge geringer Höhe an der den Hohlraum begrenzenden Innenwandfläche des Hohlprofilstücks und/oder der Außenfläche des Pfostens ausgebildet sein. Um die Wiederverwendbarkeit des Holprofilstücks nach Entfernen eines Pfostens nicht zu beeinträchtigen, ist es günstig, die Vorsprünge entweder nicht verformbar an der Innenwandfläche des Hohlprofilstücks oder verformbar an der Außenfläche des Pfostens auszubilden.For the same purpose, small height projections can be made on the cavity delimiting inner wall surface of the hollow profile piece and / or the outer surface of the post. To the reusability of the Holprofilstücks after removing a post, it does not interfere favorable, the projections either not deformable on the inner wall surface of the Form hollow profile piece or deformable on the outer surface of the post.
Gemäß einer Weiterbildung der Erfindung ist ein Verschlußstück vorgesehen, das das obere Ende des Hohlprofilstücks während dessen Verankerung im Fundament verschließt, um ein Eindringen von Fundamentmaterial zu verhindern. Zum gleichen Zweck kann mit dem gleichen Verschlußstück auch das untere Ende des Hohlprofilstücks verschlossen werden.According to a development of the invention, a closure piece is provided, the the upper end of the hollow profile piece during its anchoring in Foundation closed to prevent penetration of foundation material. For the same purpose, this can also be done with the same closure piece the lower end of the hollow profile piece are closed.
Um das Herausziehen aus den Hohlprofilstücken zu erleichtern, weist jeder Pfosten vorzugsweise wenigstens eine Öffnung und/oder einen Vorsprung auf, mit der bzw. dem beispielsweise ein Zughaken einer Winde in Eingriff gebracht werden kann.To make it easier to pull them out of the hollow profile pieces, everyone has Preferably at least one opening and / or a projection on, with which, for example, a pulling hook of a winch engages can be brought.
