Description

    RÜCKHALTESYSTEM FÜR FAHRZEUGE IM BEREICH VON STRASSENRESTRAINT SYSTEM FOR VEHICLES IN THE AREA OF ROADS Technisches GebietTechnical area
  • Die Erfindung betrifft ein Rückhaltesystem gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a restraint system according to the preamble of claim 1.
    • Stand der TechnikState of the art
  • Bei einem bekannten derartigen Rückhaltesystem (siehe EP 1910622 B ) sind Sicht- und/oder Schallschutzelemente mit einem einstückig angeformten Fuß versehen, der sich nach beiden Seiten des Schutzelementes er­streckt und auf dem zumindest an einer Seite Abweiselemente aufgestellt sind. In a known such restraint system (see EP 1910622 B ) visual and / or soundproofing elements are provided with an integrally formed foot which extends to both sides of the protective element and are mounted on the at least one side deflectors.
  • Bei dieser bekannten Lösung ergibt sich der Nachteil, dass die Herstellung der Schutzelemente einen hohen Aufwand erfordert, ins­besondere aufgrund der erforderlichen Schalung zur Herstellung der Elemente aus einer erhärtenden plastischen Masse, wie z.B. Beton. Außerdem ist es bei diesem System erforderlich, die Schutzelemente und die Abweiselemente über eingearbeitete Zugelemente zu verbin­den, um über eine längere Strecke ein derartiges System auf­bauen zu können.In this known solution, there is the disadvantage that the production of the protective elements requires a great deal of effort, in particular due to the required formwork for producing the elements from a hardening plastic mass, such. Concrete. In addition, it is necessary in this system to connect the protective elements and the Abweiselemente via incorporated tension elements in order to build over a longer distance such a system can.
  • Weiters ist aus der AT 502935 B ein System bekannt, bei dem die Sicht- und/oder Schallschutzelemente an der Oberseite der Abweis­elemente befestigt sind. Furthermore, is from the AT 502935 B a system is known in which the visual and / or soundproofing elements are attached to the top of the deflector elements.
  • Bei dieser Lösung ergibt sich das Problem, dass sich aufgrund der Windkräfte im Bereich des Anschlusses der Schutzelemente an den Abweiselementen große Biegekräfte ergeben und die Montage vor Ort einen hohen Arbeitsaufwand erfordert. Auch bei diesem System ist es erforderlich, die Abweiselemente und die Schutzelemente zugfest miteinander zu verbinden, um im Falle eines Aufpralls ei­nes Fahr­zeugs ein Ausscheren eines einzelnen Elementes aus dem Verband der Elemente zu verhindern.In this solution, there is the problem that arise due to the wind forces in the area of the connection of the protective elements on the deflector large bending forces and on-site assembly requires a lot of work. In this system, too, it is necessary to connect the deflector elements and the protective elements with high tensile strength in order to prevent an individual element from breaking out of the association of the elements in the event of a collision of a vehicle.
  • Ein Rückhaltesystem der eingangs genannten Art ist aus der US 7220077 B bekannt. Es werden dort an die Flachseiten der Ab­weiselemente Schallschutzelemente geschraubt. Nachteilig ist da­bei, dass die Abweiselemente sehr stabil im Boden verankert werden müssen, denn sonst könnte die gesamte Konstruktion im Falle eines heftigen Anpralls (z.B. durch einen LKW) umkippen.A restraint system of the type mentioned is from the US 7220077 B known. There are screwed to the flat sides of the deflector sound insulation. A disadvantage is that the deflector must be anchored very stable in the ground, otherwise the entire construction could fall over in the event of a heavy impact (eg by a truck).
    • Darstellung der ErfindungPresentation of the invention
  • Ziel der Erfindung ist es, diesen Nachteil zu vermeiden und ein Rückhaltesystem der eingangs erwähnten Art vorzuschlagen, dessen einzelne Teile sich einfach herstellen lassen und die sich einfach zu einer fortlaufend verbundenen Wand montieren lassen, wobei die Gefahr des Umkippens deutlich verringert sein soll.The aim of the invention is to avoid this disadvantage and to propose a restraint system of the type mentioned, whose individual parts can be easily manufactured and can be easily assembled to a continuously connected wall, the risk of tipping should be significantly reduced.
  • Erfindungsgemäß wird dies bei einem Rückhaltesystem der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruchs 1 erreicht.This is achieved according to the invention in a restraint system of the type mentioned by the characterizing features of claim 1.
  • Durch die vorgeschlagenen Maßnahmen können die Sicht- und/oder Schallschutzelemente, die im Folgenden als Schutzelemente bezeich­net werden, von den Abweiselementen und deren Abstützungen gehal­ten werden. Die Kippachse liegt dadurch an der hinteren Kante der Abstützung, sodass im Fall eines Unfalls nicht nur ‑ wie bei der US 7220077 B ‑ das Abweiselement, sondern auch die gesamte Schutz­wand (und in geringerem Ausmaß auch die Abstützung) gehoben werden müsste. Somit wird das Gewicht der Schutzwand zur Erhöhung der Stabilität gegen Kippen ausgenützt.By the proposed measures, the visual and / or soundproofing elements, which are referred to below as protective elements, are held by the deflector elements and their supports. The tilting axis is thereby at the rear edge of the support, so that in case of an accident not only - as with the US 7220077 B - The deflector, but also the entire protective wall (and to a lesser extent, the support) would have to be lifted. Thus, the weight of the protective wall to increase the stability against tilting is utilized.
  • Dennoch lassen sich die Schutzelemente und die Abweiselemente mit einfachen Formen bzw. Schalungen aus einer erhärtenden Masse, wie Beton, herstellen. Nevertheless, the protective elements and the Abweiselemente with simple forms or formwork from a hardening mass, such as concrete, produce.
  • Durch die Merkmale des Anspruchs 2 ergeben sich zwei Vorteile: Einerseits handelt es sich um eine sehr einfach zu reali­sierende Verbindung zwischen den Abweiselementen und den Abstüt­zun­gen, an­dererseits wird durch diese Verbindung ein Verschieben der Schutz­wand in Längsrichtung verhindert.Due to the features of claim 2, there are two advantages: on the one hand it is a very easy to implement connection between the deflector elements and the supports, on the other hand, a displacement of the protective wall in the longitudinal direction is prevented by this connection.
  • Besonders vorteilhaft ist es, die Merkmale des Anspruchs 3 vor­zusehen. Dadurch ergibt sich ständig (nicht nur im Falle eines Un­falls) eine statisch bestimmte Auflage der Schutzelemente, wobei deren Gewicht den Verschiebewiderstand der Abweiselemente im Falle eines Aufpralls eines Fahrzeuges erhöht.It is particularly advantageous to provide the features of claim 3. This results constantly (not only in the case of an accident) a statically determined edition of the protective elements, the weight of which increases the resistance to displacement of the deflector elements in the event of a collision of a vehicle.
  • Um plötzliche Belastungen der Abweiselemente durch die Schutz­ele­mente in deren Einspannbereich, z.B. aufgrund von Windkräften, und damit ein Ausschlagen der entsprechenden Flächen zu vermeiden, ist es vorteilhaft, die Merkmale des Anspruchs 4 vorzusehen. Auf diese Weise wird bei einem Windangriff ein im Wesentlichen verlau­fender Anstieg der Belastung des Abweiselementes bzw. dessen Ab­stützung sichergestellt, und es können Toleranzen ausgeglichen wer­den.In order to prevent sudden loads on the repelling elements by the protective elements in their clamping area, e.g. Due to wind forces, and thus to avoid deflection of the corresponding surfaces, it is advantageous to provide the features of claim 4. In this way, in a wind attack, a substantially extending increase in the load of the Abweiselementes or its support is ensured, and tolerances can be compensated.
  • Um eine einfache Montage der Schutzelemente zu ermöglichen, ist es zweckmäßig, die Merkmale des Anspruchs 5 vorzusehen. So wird aufgrund der Verjüngung der Dicke der Schutzelemente ein Einsetzen der Schutzelemente zwischen die einander zugekehrten Flächen der Abweiselemente und deren Abstützungen wesentlich erleichtert.In order to allow easy mounting of the protective elements, it is expedient to provide the features of claim 5. Thus, due to the taper of the thickness of the protective elements insertion of the protective elements between the mutually facing surfaces of the Abweiselemente and their supports is much easier.
  • Dabei ergibt sich bei einer durchgehend ebenen Ausführung einer Seite der Schutzelemente eine Vereinfachung der erforderlichen Schalungen, wodurch die Herstellungskosten der Elemente gesenkt werden.This results in a continuous planar design of one side of the protective elements simplification of the required formwork, whereby the manufacturing cost of the elements are reduced.
  • In einer alternativen Ausfüh­rungsform der Erfindung sind zur Lö­sung der Aufgabe die Merkmale des Anspruchs 6 vorzusehen. Um beim Aufstellen des Rückhaltesys­tems möglichst wenig Einzelteile zu be­nötigen, ist es vorteilhaft die Merkmale des Anspruchs 7 vorzuse­hen.In an alternative embodiment of the invention, the features of claim 6 are provided to achieve the object. In order to use as few individual parts when setting up the restraint system, it is advantageous to provide the features of claim 7.
  • Nach einer weiteren alternativen Ausführungsform kann auch vor­gesehen sein, dass die Abweiselemente direkt (also nicht über die Schutzwand) durch Zugelemente mit den Abstützungen verbunden sind, welche die Schutzwand durchsetzten.According to a further alternative embodiment can also be provided that the deflector elements are connected directly (ie not on the protective wall) by tension elements with the supports, which penetrated the protective wall.
  • Durch die Merkmale des Anspruchs 9 ergibt sich der Vorteil, dass auf einfache Weise das erfindungsgemäße Rückhaltesystem auch als Fahrbahnteiler eingesetzt werden kann. Die Herstellung solcher Ab­weiselemente kann dabei einfach in im Wesentlichen trogförmigen Formen erfolgen, in die entsprechende Kerne eingesetzt werden, wo­bei zwischen den einzelnen Kernen Abstände zur Ausbildung der Ver­bindungsstege frei gelassen werden. Due to the features of claim 9, there is the advantage that in a simple way the restraint system according to the invention can also be used as a roadway divider. The production of such deflector elements can easily be carried out in essentially trough-shaped molds, in which corresponding cores are used, wherein spacings between the individual cores for the formation of the connecting webs are left free.
  • Bei einem erfindungsgemäßen Rückhaltesystem nach Anspruch 10 kann auf eine zugfeste Verbindung der einzelnen Elemente in Längs­richtung zur Sicherung gegen einen Durchbruch im Falle eines Auf­pralls verzich­tet werden, wodurch sich eine wesentliche Kostenre­duktion ergibt. Dabei wird durch die Versetzung der Trennfugen zwischen den Ab­weiselementen einerseits und den Schutzelementen andererseits ein sehr fester Verbund der Elemente erreicht, wo­durch einzelne Ele­mente erst nach einem vollständigen Bruch entwe­der eines Schutz­elementes oder eines Abweiselementes aus dem Ver­bund derselben ausgeschoben wer­den können.In a restraint system according to the invention according to claim 10 can be dispensed with a tensile strength connection of the individual elements in the longitudinal direction to protect against breakthrough in the event of an impact, resulting in a significant cost reduction. In this case, a very firm composite of the elements is achieved by the displacement of the joints between the Abweiselementen one hand, and the protective elements on the other hand, whereby individual elements can be pushed out of the composite of the same after a complete break either a protective element or a Abweiselementes.
  • Um ein besonderes hohes Maß an Aufprallenergie absorbieren zu können und eine niedrige Insassenbelastung bei einem Aufprall ei­nes leichten Fahrzeugs sicherzustellen, ist es vorteilhaft, die Merkmale des Anspruches 11 vorzu­sehen.To be able to absorb a particularly high level of impact energy and a low occupant load in an impact To ensure a light vehicle, it is advantageous to provide the features of claim 11.

    • Weg(e) zur Ausführung der ErfindungWay (s) for carrying out the invention
  • Bei dem Rückhaltesystem gemäß den Fig. 1 und 2 sind Sicht- und bzw. oder Schallschutzelemente 1 (im weiteren kurz Schutzelemente 1 genannt) von Abweiselementen 2 gehalten. Dabei weisen die Abweis­elemente 2 Abstützungen 4 auf, die über Verbindungsstege 3 mit diesen verbunden sind. Diese Verbindungsstege 3 erstrecken sich im Wesentlichen von der Aufstandsfläche bis zur Oberseite der Abweis­elemente 2. In the restraint system according to FIGS. 1 and 2, visual and / or soundproofing elements 1 (referred to below as protective elements 1 for short) are held by deflector elements 2. In this case, the deflector elements 2 supports 4, which are connected via connecting webs 3 with these. These connecting webs 3 extend substantially from the footprint to the top of the deflectors 2.
  • Die Verbindungsstege 3 sind schmäler als die Abstützungen 4, wo­bei sich die Verbindungsstege 3 von Verstärkungsrippen 5, die sich gegen das Innere der Abweiselemente 2 erstrecken, weg erstrecken (Fig. 4)The connecting webs 3 are narrower than the supports 4, with the connecting webs 3 extending away from reinforcing ribs 5 which extend against the interior of the deflecting elements 2 (FIG. 4)
  • An den Enden eines jeden Abweiselementes 2 sind Verstärkungs­rip­pen 5’ und Verbindungsstege 3’ sowie die Abstützungen 4’ mit je­weils vorzugsweise der halben Breite der übrigen Verstärkungsrip­pen 5 bzw. Verbindungsstege 3 bzw. Abstützungen 4 vorgesehen. Da­bei bilden diese halben Verstärkungsrippen 5’ ebene Stirnseiten der Abweis­elemente 2, sodass eine gute Anlage benachbarter Abweis­elemente 2 aneinander beim Aufbau eines Rückhaltesystems sicherge­stellt ist.At the ends of each Abweiselementes 2 reinforcing ribs 5 'and connecting webs 3' and the supports 4 ', each with preferably half the width of the other reinforcing ribs 5 or connecting webs 3 or supports 4 are provided. In this case, these half reinforcing ribs 5 'form flat end faces of the deflector elements 2, so that a good contact of adjacent deflector elements 2 is secured to each other during the construction of a restraint system.
  • Die Schutzelemente 1 weisen an deren Unterkante offene Schlitze 6 auf, deren Breite im Wesentlichen der Breite der Verbindungs­stege 3 zuzüglich erforderlicher Montagetoleranzen entspricht. Durch unterschiedliche Spaltausbildung zwischen den Stegen der Ab­weiselemente und der Sicht- und/oder Schallschutzelemente kann er­reicht werden, dass durch die im Falle eines Anpralls entstehende Verschiebung des Systems eine verlaufende Energieabsorbierung er­folgt. Im montierten Zustand der Schutzelemente 1 greifen die Ver­bindungsstege 3 in die Schlitze 6 der Schutzele­mente 1 ein. Dabei ist die Tiefe der Schlitze 6 etwas geringer als die Höhe der Ab­weiselemente 2, sodass die Schutzelemente auf den Verbindungsste­gen 3, 3’ aufsitzen und zwischen der Unterkante der Schutzelemente 1 und der Aufstandsfläche der Abweiselemente 2 ein kleiner Spalt 7 verbleibt. Damit ist sichergestellt, dass das ge­samte Gewicht der Schutzelemente 1 auf den Abweiselementen 2 las­tet und diese einen entsprechend hohe Kippsicherheit bei Windbelastung oder einem Auf­prall aufweisen.The protective elements 1 have at their lower edge open slots 6, the width of which substantially corresponds to the width of the connecting webs 3 plus required mounting tolerances. By different gap formation between the webs of the deflector and the visual and / or soundproofing elements can be achieved that occurs by the resulting in case of an impact displacement of the system, a running energy absorption. In the mounted state of the protective elements 1, the connecting webs 3 engage in the slots 6 of the protective elements 1. The depth of the slots 6 is slightly less than the height of the deflector elements 2, so that the protective elements on the connecting webs 3, 3 'sit and between the lower edge of the protective elements 1 and the footprint of the deflector 2 remains a small gap 7. This ensures that the entire weight of the protective elements 1 rests on the deflector elements 2 and that they have a correspondingly high resistance to tipping when exposed to wind or an impact.
  • Wie aus Fig. 3 zu ersehen ist, verjüngt sich die Dicke der Schutzelemente 1 in ihrem unteren, in die Abweiselemente 2 ein­greifenden Abschnitt 8 gegen die Unterkante der Schutzelemente 1 zu. Dabei ist eine den Abweiselementen 2 zugekehrte durchgehend ebene Fläche 9 vorgesehen. Die einander zugekehrten Flächen der Verstärkungsrippen 5, 5’ und der Abstützungen 4, 4’ sind im We­sentlichen gegengleich zu den Flächen 9 und den schräg verlaufen­den Flächen 10 der Abschnitte 8 der Schutzelemente 1 ausgebildet.As can be seen from Fig. 3, the thickness of the protective elements 1 tapers in its lower, engaging in the deflector 2 section 8 against the lower edge of the protective elements 1 to. In this case, a deflecting elements 2 facing continuous flat surface 9 is provided. The mutually facing surfaces of the reinforcing ribs 5, 5 'and the supports 4, 4' are formed substantially opposite to the surfaces 9 and the inclined surfaces 10 of the sections 8 of the protective elements 1.
  • In den Endbereichen der Schutzelemente sind Ausnehmungen 6’ vor­gesehen, die vorzugsweise den halben Schlitzen 6 entsprechen (Fig. 1).In the end regions of the protective elements recesses 6 'are provided, which preferably correspond to half the slots 6 (Fig. 1).
  • Grundsätzlich können die Verstärkungsrippen 6’ und die Verbin­dungsstege 3’ wie auch die Abstützungen 4’ in den Endbereichen der Abweiselemente 2 auch die volle Breite der übrigen Verstär­kungs­rippen 6, Verbindungsstege 3 und Abstützungen 4 aufweisen, je­doch müssen dann die Ausnehmungen 6’ in den Endbereichen der Schutzele­mente entsprechend ausgebildet sein.Basically, the reinforcing ribs 6 'and the connecting webs 3' as well as the supports 4 'in the end regions of the Abweiselemente 2 also the full width of the other reinforcing ribs 6, connecting webs 3 and 4 supports have, but then the recesses 6' in the end of the Be designed protection elements accordingly.
  • Bei der Ausführungsform gemäß Fig. 5 ist die Abstützung 4 durch ein zum Abweiselement 2 im Wesentlichen spiegelbildlich aus­geführ­tes Abweiselement 41 ersetzt. Dabei sind zwischen den Ab­weisele­menten 4, 41 Verbindungsstege 3 vorgesehen, auf denen die Schutz­elemente 1 aufsitzen. In the embodiment according to FIG. 5, the support 4 is replaced by a deflector element 41, which is designed essentially mirror-inverted to the deflector element 2. In this case, 41 connecting webs 3 are provided between the deflector elements 4, on which the protective elements 1 sit.
