Description

Die Erfindung betrifft ein Notfallöffnungsleitwandelement gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an emergency opening guide wall element according to the preamble of claim 1.

Es sind Fahrzeugrückhaltesysteme bekannt, welche aus vielen Leitwandelementen ausgebildet sind. Derartige Leitwandelemente können als Betonfertigteile ausgebildet sein, da diese durch die hohe Masse und die Form eine sehr hohe Rückhaltewirkung aufweisen. An einigen Stellen des Fahrzeugrückhaltesystems ist es oftmals erforderlich, dass die Möglichkeit der Bildung einer Lücke in diesem Fahrzeugrückhaltesystem, eine sogenannte Notfallöffnung, besteht, beispielsweise damit Einsatzfahrzeuge bei einer Mittelstreifenabsicherung auf Autobahnen auf die Gegenfahrbahn können oder der Verkehr im Falle einer gesperrten Fahrbahn über die Gegenfahrbahn umgeleitet werden kann. Hierbei ist es ohne Einsatz von schwerem Gerät wie Kränen nicht möglich ein herkömmliches Leitwandelement zu bewegen und derart eine Notfallöffnung auszubilden. Eine Lösung ist es an vorgegebenen Stellen ein Notfallöffnungsleitwandelement in den Verbund der Leitwandelemente einzugliedern, welches von Hand bewegt werden kann.There are known vehicle restraint systems which are formed from many baffle elements. Such Leitwandelemente can be designed as precast concrete parts, as they have a very high retention effect by the high mass and shape. In some places of the vehicle restraint system, it is often required that the possibility of forming a gap in this vehicle restraint system, a so-called emergency opening exists, for example, emergency vehicles in a median strip protection on highways on the opposite lane or the traffic in the case of a locked lane on the opposite lane can be redirected. It is not possible without the use of heavy equipment such as cranes to move a conventional baffle element and thus form an emergency opening. One solution is to incorporate at predetermined locations an emergency opening guide wall element in the composite of the baffle elements, which can be moved by hand.

Eine bekannte Lösung ist es Notfallöffnungsleitwandelemente einzusetzen, welche von einigen Personen per Hand aufgehoben und transportiert werden können. Dafür muss dieses Notfallöffnungsleitwandelement wesentlich leichter gebaut werden, beispielsweise als reine Stahlkonstruktion, als die anderen Leitwandelemente. Durch dieses geringe Gewicht stellt ein derartiges Notfallöffnungsleitwandelement allerdings eine erhebliche Schwächung in dem Fahrzeugrückhaltesystem, da es sich bei einem Fahrzeuganprall wesentlich anders verhält als die sonstigen Leitwandelemente. Dadurch wird die Rückhaltewirkung des gesamten Fahrzeugrückhaltesystems wesentlich geschwächt. Durch die Bauart sind derartige Notfallöffnungsleitwandelemente auch wesentlich teurer und aufwendiger als herkömmliche Leitwandelemente.A known solution is to use emergency opening guide wall elements, which can be picked up and transported by some people by hand. For this Notfallöffnungsleitwandelement must be much easier to build, for example, as a pure steel structure, as the other Leitwandelemente. Due to this low weight, however, such an emergency opening guide wall element represents a considerable weakening in the vehicle restraint system, since it behaves significantly differently in a vehicle impact than the other guide wall elements. As a result, the retention effect of the entire vehicle restraint system is significantly weakened. Due to the design of such emergency opening guide wall elements are also much more expensive and expensive than conventional baffle elements.

Aus der US 2007/0160420 A1 ist ein Fahrzeugrückhaltesystem aus mehreren Leitwandelementen aus Beton bekannt. Die Leitwandelemente haben an der Unterseite ausfahrbare Fahreinheiten, um die Leitwandelemente quer zu deren Längsrichtung zu bewegen, wobei die Leitwandelemente allerdings stets ein durchgehendes Fahrzeugrückhaltesystem bilden.From the US 2007/0160420 A1 For example, a vehicle restraint system comprising a plurality of concrete baffle elements is known. The baffle elements have retractable drive units on the underside to move the baffle elements transversely to their longitudinal direction, but the baffle elements always form a continuous vehicle restraint system.

Aus der US 5 007 763 A ist ein Fahrzeugrückhaltesystem aus mehreren Leitwandelementen aus Beton bekannt. Die Leitwandelemente haben an der Unterseite über eine Hydraulik ausfahrbare Fahreinheiten, damit das gesamte Fahrzeugrückhaltesystem ähnlich einem Zug gezogen werden kann.
Aus der FR 2 741 093 A1 ist ein bewegliches Fahrzeugrückhaltesystem mit einem durchgehenden Rahmen bekannt, wobei der Rahmen in einer Knickachse steif ist, aber in einer Kippachse beweglich, sodass das Fahrzeugrückhaltesystem gegen seitliche Belastungen formstabil ist, aber Bodenunebenheiten wie Mulden und dergleichen ausgleichen kann.
Aus der EP 0 758 698 A1 ist ein Fahrzeugrückhaltesystem bekannt, mit welchem schnell eine Öffnung in einer Leitwand erzeugt werden kann. Hierbei sind bewegliche Leitwandelemente aus Metall vorgesehen, welche in einer Verriegelungsposition in dem Boden verankert sind, wobei bei Bedarf durch ein Heben der metallenen Leitwandelemente die Verriegelung gelöst wird, um die auf Rollen beweglichen Leitwandelemente wegzuschwenken.
Aufgabe der Erfindung ist es daher ein Notfallöffnungsleitwandelement der eingangs genannten Art anzugeben, mit welchem die genannten Nachteile vermieden werden können, mit welchem es möglich ist schnell und zuverlässig eine Notfallöffnung in einem Fahrzeugrückhaltesystem auszubilden, wobei die Rückhaltewirkung des Fahrzeugrückhaltesystems hoch bleibt, und welches dennoch einfach herzustellen ist.From the US 5 007 763 A For example, a vehicle restraint system comprising a plurality of concrete baffle elements is known. The baffle elements have hydraulically extendable drive units at the bottom so that the entire vehicle restraint system can be pulled like a train.
From the FR 2 741 093 A1 a movable vehicle restraint system is known with a continuous frame, wherein the frame is rigid in a bending axis, but movable in a tilting axis, so that the vehicle restraint system is dimensionally stable against lateral loads, but can compensate for uneven ground such as troughs and the like.
From the EP 0 758 698 A1 For example, a vehicle restraint system is known that can quickly create an opening in a baffle. Here, movable baffle elements are provided of metal, which are anchored in a locking position in the ground, wherein if necessary by lifting the metal baffle elements, the lock is released to wegzuschwenken the movable guide vanes on rollers.
The object of the invention is therefore to provide a Notfallöffnungsleitwandelement of the type mentioned, with which the mentioned disadvantages can be avoided, with which it is possible to quickly and reliably form an emergency opening in a vehicle restraint system, the retention effect of the vehicle restraint system remains high, and yet easy is to produce.

Erfindungsgemäß wird dies durch die Merkmale des Patentanspruches 1 erreicht.This is achieved by the features of claim 1 according to the invention.

Dadurch ergibt sich der Vorteil, dass das Notfallöffnungsleitwandelement im Wesentlichen die gleich hohe Rückhaltewirkung aufweisen kann wie die restlichen Leitwandelemente in dem Fahrzeugrückhaltesystem, wodurch das gesamte Fahrzeugrückhaltesystem eine hohe Rückhaltewirkung ohne Schwachstellen aufweisen kann. Wenn die Fahreinheit in der Ruheposition ist, liegt das Notfallöffnungsleitwandelement wie ein herkömmliches Leitwandelement auf der Aufstellfläche auf, wobei durch die Masse des Betonkörpers und die Reibung der Aufstellfläche mit dem Boden auch eine ähnlich hohe Rückhaltewirkung wie ein herkömmliches Leitwandelement erreicht werden kann. Um das Notfallöffnungsleitwandelement zu zum Bilden einer Notfallöffnung zu bewegen, wird die wenigstens eine Fahreinheit in eine Fahrposition gebracht werden, bei der die wenigstens eine Fahreinheit die durch die Aufstellfläche aufgespannte Aufstellebene durchdringt, den Boden kontaktiert, und dabei die Aufstellfläche von dem Boden abhebt. Das durch dieses wenigstens einen Fahreinheit fahrbar gemachte Notfallöffnungsleitwandelement kann dann aus dem Verbund der Leitwandelemente heraus bewegt werden, wodurch die Notfallöffnung gebildet wird. Abseits von der zusätzlichen wenigstens einen Fahreinheit kann der restliche Aufbau dem Aufbau eines herkömmlichen Leitwandelementes entsprechen, wodurch das Notfallöffnungsleitwandelement kaum aufwendiger gestaltet ist als ein übliches Leitwandelement.This results in the advantage that the Notfallöffnungsleitwandelement can have substantially the same high retention effect as the remaining Leitwandelemente in the vehicle restraint system, whereby the entire vehicle restraint system can have a high retention effect without vulnerabilities. When the driving unit is in the rest position, the emergency opening guide wall element rests on the installation surface like a conventional guide wall element, whereby the mass of the concrete body and the friction of the installation surface with the floor can also achieve a similar retention effect as a conventional guide wall element. In order to move the Notfallöffnungsleitwandelement to form an emergency opening, the at least one driving unit will be brought into a driving position in which the at least one driving unit penetrates the mounting plane spanned by the mounting surface, the ground contacted, while the footprint from the ground lifts. The Notfallöffnungsleitwandelement made mobile by this at least one driving unit can then be moved out of the composite of the baffle elements, whereby the emergency opening is formed. Apart from the additional at least one driving unit, the remaining structure may correspond to the structure of a conventional baffle element, whereby the Notfallöffnungsleitwandelement is designed hardly more expensive than a conventional baffle element.

Weiters betrifft die Erfindung ein Verfahren zum Bilden einer Notfallöffnung in einem Fahrzeugrückhaltesystem gemäß dem Patentanspruch 14.Furthermore, the invention relates to a method for forming an emergency opening in a vehicle restraint system according to claim 14.

Aufgabe der Erfindung ist es daher weiters ein Verfahren zum Bilden einer Notfallöffnung in einem Fahrzeugrückhaltesystem anzugeben, mit welchem die genannten Nachteile vermieden werden können, mit welchem es möglich ist schnell und zuverlässig eine Notfallöffnung in einem Fahrzeugrückhaltesystem auszubilden, wobei die Rückhaltewirkung des Fahrzeugrückhaltesystems, wenn die Notfallöffnung nicht geöffnet ist, im Wesentlichen unverändert bleibt.The object of the invention is therefore further to provide a method for forming an emergency opening in a vehicle restraint system, with which the mentioned disadvantages can be avoided, with which it is possible to quickly and reliably form an emergency opening in a vehicle restraint system, wherein the retention effect of the vehicle restraint system, if the Emergency opening is not open, essentially unchanged.

Die Vorteile dieses Verfahrens entsprechen den Vorteilen des Notfallöffnungsleitwandelementes.The advantages of this method correspond to the advantages of the emergency opening guide wall element.

Das Notfallöffnungsleitwandelement 1 kann Teil eines Fahrzeugrückhaltesystems 8 sein, wobei das Notfallöffnungsleitwandelement 1 statt einem herkömmlichen Leitwandelement 25 in dem Fahrzeugrückhaltesystem 8 angeordnet sein kann. Im Gegensatz zu einem herkömmlichen Leitwandelement 25 ist das Notfallöffnungsleitwandelement 1 ausgebildet, ohne Einsatz eines Kranes oder ähnlichem schweren Gerät entfernt zu werden, um in einem Fahrzeugrückhaltesystem 8 eine Notfallöffnung, also eine Lücke in dem Fahrzeugrückhaltesystem 8 durch welche Fahrzeuge ungehindert das Fahrzeugrückhaltesystem 8 durchqueren können, zu bilden.

In contrast to a conventional baffle element 25 is the Notfallöffnungsleitwandelement 1 adapted to be removed without the use of a crane or similar heavy equipment to form in a vehicle restraint system 8 an emergency opening, ie a gap in the vehicle restraint system 8 through which vehicles can pass through the vehicle restraint system 8 unhindered. Here, the formation of such an emergency opening is not limited to emergencies, but may also be formed in other events, such as the formation of a diversion during construction.

Das Notfallöffnungsleitwandelement 1 kann insbesondere als Fertigteil, bevorzugt als Betonfertigteil, ausgebildet sein kann, welches bevorzugt vorfabriziert wird und anschließend zum Einsatzort gebracht werden kann.

The concrete body 2 may consist of concrete or a concrete mixture. Furthermore, it can be provided that the concrete body 2 has a New Jersey profile or a step profile. The concrete body 2 is in the Fig. 1 and 2 partially transparent, so that concealed features are visible through the concrete body 2.

Das Notfallöffnungsleitwandelement 1 weist weiters eine Aufstellfläche 5 auf, auf welcher das Notfallöffnungsleitwandelement 1 großflächig auf einem ebenen Boden 26 aufliegen kann. Die Aufstellfläche 5 spannt hierbei eine gedachte Aufstellebene auf. Die Aufstellfläche 5 kann insbesondere eine Unterseite des Betonkörpers 2 sein. Alternativ kann vorgesehen sein, dass der Betonkörper 2 an der Unterseite eine Bodenplatte aufweist, welche die Aufstellfläche 5 ausbildet.The Notfallöffnungsleitwandelement 1 further has a footprint 5, on which the Notfallöffnungsleitwandelement 1 can rest over a large area on a flat floor 26. The footprint 5 in this case spans an imaginary set-up level. The footprint 5 may in particular be an underside of the concrete body 2. Alternatively it can be provided that the concrete body 2 has a bottom plate on the underside, which forms the footprint 5.

Vorgesehen ist, dass das Notfallöffnungsleitwandelement 1 wenigstens eine Fahreinheit 3 aufweist, dass die wenigstens eine Fahreinheit 3 zwischen einer Ruheposition und einer Fahrposition bewegbar ausgebildet ist, dass die wenigstens eine Fahreinheit 3 in der Ruheposition komplett auf einer dem Betonkörper 2 zugewandten Seite der Aufstellebene angeordnet ist, und dass die wenigstens eine Fahreinheit 3 in der Fahrposition, zum Fahren des Notfallöffnungsleitwandelementes 1 auf der wenigstens einen Fahreinheit 3, die Aufstellebene durchdringt.It is provided that the Notfallöffnungsleitwandelement 1 comprises at least one driving unit 3, that the at least one driving unit 3 is movable between a rest position and a driving position that the at least one driving unit 3 is completely arranged in the rest position on a side facing the concrete body 2 of the mounting plane , and that the at least one driving unit 3 in the driving position, for driving the Notfallöffnungsleitwandes 1 on the at least one driving unit 3, which penetrates the installation level.

Dadurch ergibt sich der Vorteil, dass das Notfallöffnungsleitwandelement 1 eine hohe Rückhaltewirkung aufweisen kann, wodurch das gesamte Fahrzeugrückhaltesystem 8 eine hohe Rückhaltewirkung ohne Schwachstellen aufweisen kann. Wenn die Fahreinheit 3 in der Ruheposition ist, liegt das Notfallöffnungsleitwandelement 1 wie ein herkömmliches Leitwandelement 25 auf der Aufstellfläche 5 auf, wobei durch die Masse des Betonkörpers 2 und die Reibung der Aufstellfläche 5 mit dem Boden 26 auch eine ähnlich hohe Rückhaltewirkung wie ein herkömmliches Leitwandelement 25 erreicht werden kann. Um das Notfallöffnungsleitwandelement 1 zu zum Bilden einer Notfallöffnung zu bewegen, wird die wenigstens eine Fahreinheit 3 in eine Fahrposition gebracht werden, bei der die wenigstens eine Fahreinheit 3 die durch die Aufstellfläche 5 aufgespannte Aufstellebene durchdringt, den Boden 26 kontaktiert, und dabei die Aufstellfläche 5 von dem Boden 26 abhebt.

Abseits von der zusätzlichen wenigstens einen Fahreinheit 3 kann der restliche Aufbau des Notfallöffnungsleitwandelementes 1 dem Aufbau eines herkömmlichen Leitwandelementes 25 entsprechen, wodurch das Notfallöffnungsleitwandelement 1 kaum aufwendiger gestaltet ist als ein übliches Leitwandelement 25.This results in the advantage that the Notfallöffnungsleitwandelement 1 may have a high retention effect, whereby the entire vehicle restraint system 8 may have a high retention effect without vulnerabilities. When the drive unit 3 is in the rest position, the emergency opening guide wall element 1 rests on the installation surface 5 like a conventional guide wall element 25, whereby the mass of the concrete body 2 and the friction of the installation surface 5 with the floor 26 also have a similarly high retention effect as a conventional guide wall element 25 can be achieved.
