Abstract

The safety barrier, to prevent loads being ejected from motor vehicles in the event of a collision, has a number of posts, each with an anchor, along the side of the road on a foundation strip or a road construction cap. A number of longitudinal profiles and grid sections are mounted to the posts at height intervals forming the impact side of the structure. The barrier is at least 3 m high, and lies behind a vehicle guard. The post anchors have a holding force which is below the breaking limit of the foundation or cap mounting and/or the posts have a nominal bending point at a maximum of 1200 mm over the anchor plate.

Description

Die Erfindung betrifft eine Anordnung nach dem Oberbegriff des Anspruchs 1.The invention relates to an arrangement according to the preamble of claim 1.

Im Stand der Technik ist durch die gattungsbildende DE-A-100 62 648 eine Absturzsicherungen bekannt, die sich entlang der Fahrbahn erstrecken. Diese umfasst eine fahrwegseitige Schutzeinrichtung, eine äussere Schutzeinrichtung sowie eine mittlere Schutzeinrichtung, die seitlich nachgeben kann. Sie können jedoch nicht verhindern, dass bei einem Anprall eines Fahrzeuges aufgrund der Richtungsänderung oder der negativen Beschleunigung das Fahrzeug eine Last abwirft und diese auf einem anderen Verkehrsweg Dritte gefährdet und erhebliche Schäden verursacht.In the prior art is by the generic DE-A-100 62 648 a fall protection known, which extend along the roadway. This includes a guideway-side protection, an outside guard and a center guard that can yield laterally. However, they can not prevent the vehicle from dropping a load in the event of a collision with a vehicle due to the change in direction or the negative acceleration, causing it to endanger third parties and causing considerable damage on another route.

Im Stand der Technik ist zudem durch die DE-U-201 14 675 ein Brückengeländer bekannt geworden, das zwischen Pfosten angeschraubte Gitterelemente und einen hohlen Handlauf besitzt. Das Gitter soll in der Lage sein, auch schwere Fahrzeuge abzufangen. Das Gelände kann jedoch abgeworfene Ladungen nicht abfangen.In the prior art is also by the DE-U-201 14 675 a bridge railing has become known, which has bolted grid elements between posts and a hollow handrail. The grid should be able to intercept even heavy vehicles. However, the terrain can not intercept discarded cargoes.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung der genannten Art zu schaffen, welche die oben genannten Nachteile vermeidet. Die genannte Anordnung bildet einen sogenannten passiven Schutz, der verhindern soll, dass von einem Fahrzeug bei einem Anprall an einem Fahrzeugrückhaltesystem Last auf eine Gegenfahrbahn oder ein Bahntrassee abgeworfen wird, oder dort wo ein Schutz Dritter gewährleistet sein soll.The invention has for its object to provide an arrangement of the type mentioned, which avoids the disadvantages mentioned above. Said arrangement forms a so-called passive protection, which is intended to prevent a vehicle from being impacted by a vehicle restraint system on an oncoming lane or a railway track is dropped, or where a third party protection should be guaranteed.

Die Aufgabe ist bei einer gattungsgemässen Anordnung gemäss Anspruch 1 gelöst.The object is achieved in a generic arrangement according to claim 1.

Bei der erfindungsgemässen Anordnung ist die Auffangvorrichtung seitlich im Abstand zu einer Fahrzeugrückhaltevorrichtung angeordnet. Die Auffangvorrichtung wird hier lediglich dann wirksam, wenn ein Fahrzeug an der Fahrzeugrückhaltevorrichtung anprallt und eine Ladung so verschoben wird, dass sie an der Auffangvorrichtung aufprallt. In den meisten Fällen wird somit bei der erfindungsgemässen Anordnung lediglich die Fahrzeugrückhaltevorrichtung, jedoch nicht die Auffangvorrichtung, beschädigt. Wird die Auffangvorrichtung wirksam, so wird eine Beschädigung des Streifenfundamentes bzw. der Bauwerkskappe dadurch vermieden, dass gemäss Anspruch 1 die Verankerungsmittel eine Haltekraft aufweisen, die unter der Bruchgrenze des Streifenfundaments liegt und/oder die Pfosten jeweils eine Sollknickstelle aufweisen. Bei der erfindungsgemässen Anordnung löst sich bei einem Anprall somit die Verankerung und/oder die Pfosten werden geknickt. Das Streifenfundament wird hierbei nicht beschädigt, sodass die Anordnung in vergleichsweise kurzer zeit wieder hergestellt werden kann. Die vorgesehene Knickstelle befindet sich vorzugsweise höchstens 1200 mm, insbesondere etwas 1000 mm über einer Verankerungsplatte.In the inventive arrangement, the collecting device is arranged laterally spaced from a vehicle restraint device. The catching device only becomes effective here when a vehicle impacts on the vehicle restraint device and a load is displaced in such a way that it collides with the catching device. In most cases, therefore, only the vehicle restraint device, but not the catching device, is damaged in the arrangement according to the invention. If the catcher is effective, then damage to the Strip foundation or the building cap thereby avoided that according to claim 1, the anchoring means have a holding force which is below the breaking point of the strip foundation and / or the posts each have a predetermined bending point. In the case of the arrangement according to the invention, the anchoring thus releases in the event of an impact and / or the posts are kinked. The strip foundation is not damaged here, so that the arrangement can be restored in a relatively short time. The intended kink is preferably at most 1200 mm, in particular a little more than 1000 mm above an anchoring plate.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die Verankerungsmittel jeweils eine Verankerungsplatte aufweisen, die mit wenigstens zwei, vorzugsweise vier im Abstand zueinander angeordneten Verankerungsbolzen im Streifenfundament verankert sind, wobei der Abstand zwischen zwei Verankerungsbolzen wenigstens 290 mm beträgt.According to a development of the invention, it is provided that the anchoring means each have an anchoring plate, which are anchored with at least two, preferably four mutually spaced anchoring bolts in the strip foundation, wherein the distance between two anchoring bolts is at least 290 mm.

Die Figur 7 zeigt seitlich neben einer Fahrbahn 16 einen Abschnitt einer erfindungsgemässen Anordnung, die eine Fahrzeugrückhaltevorrichtung 13 der Aufhaltestufe H4b sowie eine Auffangvorrichtung 1 aufweist. Kommt ein Fahrzeug 22 von der vorgesehenen Fahrtrichtung ab, so prallt es seitlich auf die Fahrzeugrückhaltevorrichtung 13. Aufgrund der negativen Beschleunigung während der Verformungsphase ist die Wahrscheinlichkeit eines Abwurfes einer Last 23 am grössten. Die Auffangvorrichtung soll in der Anprall- und Verzögerungsphase verhindern, dass die Last 23 vom Fahrzeug rutscht und dass keine "fliegende" Ladung entsteht. Dies wird erreicht, indem die Auffangvorrichtung 1 die Ladung 23 auf dem Fahrzeug 22 zurückhält. Um einen solchen Ladungsabwurf zu verhindern, ist die Dimensionierung der Auffangvorrichtung sowie der Fahrzeugrückhaltevorrichtung 13 wesentlich. So ist der in Figur 2 gezeigte Abstand D zwischen der Fahrzeugrückhalteeinrichtung 13 und der Auffangvorrichtung 1 im Bereich von 1,2 bis 0,7 m. Die Höhe H der Auffangvorrichtung 1 beträgt wenigstens 3 m. Wie die Figur 2 deutlich zeigt, überragt die Auffangvorrichtung 1 die Fahrzeugrückhaltevorrichtung 13 wesentlich.The FIG. 7 shows next to a roadway 16 a portion of an inventive arrangement, which has a vehicle restraint device 13 of the containment stage H4b and a collecting device 1. If a vehicle 22 comes off the intended direction of travel, then it bounces laterally on the vehicle restraint device 13. Due to the negative acceleration during the deformation phase, the probability of a discharge of a load 23 is the greatest. The fall arrester is intended to prevent the load 23 from slipping off the vehicle during the impact and deceleration phases and to avoid the occurrence of a "flying" load. This is achieved by the collecting device 1, the charge 23 retains on the vehicle 22. In order to prevent such a charge discharge, the dimensioning of the collecting device and the vehicle restraint device 13 is essential. So is the in FIG. 2 shown distance D between the vehicle restraint 13 and the collecting device 1 in the range of 1.2 to 0.7 m. The height H of the collecting device 1 is at least 3 m. As the FIG. 2 clearly shows, the collecting device 1, the vehicle restraint device 13 substantially.

Die Auffangvorrichtung 1 besteht aus einer Mehrzahl von vertikalen Pfosten 2, die jeweils mit Verankerungsmitteln V an einem Streifenfundament 6 verankert sind. Die Verankerungsmittel weisen jeweils vier Verankerungsbolzen 10 auf, mit denen eine Platte 9 über einem Streifenfundament 6 befestigt ist. Denkbar ist hier auch eine Ausführung, bei welcher die Verankerungsplatten 9 auf dem Streifenfundament 6 aufliegen. In der Figur 1 sind hierbei die unteren Muttern 12 weggelassen und die Platte 9 mit den Muttern 11 auf das Fundament 6 gespannt. Auf den Platten 9 ist jeweils ein Versteifungselement 8 befestigt, beispielsweise an der unteren Kante an der Platte 9 angeschweisst, der wie ersichtlich dreieckig ist und nach oben ragt. Mit zwei im Abstand zueinander angeordneten Platten 24 sind die Versteifungselemente 8 jeweils mit einem Pfosten 2 verschweisst. Eine äussere Kante 7 des Versteifungselementes 8 nähert sich gemäss Figur 1 kontinuierlich dem Pfosten 2 und endet an einer oberen Stelle 25, an der ebenfalls die obere Platte 24 endet. An dieser Stelle 25 ist damit eine Knickstelle gebildet, an welcher die Pfosten 2 bei einer entsprechend hohen Belastung knicken. Die Pfosten 2 sind so ausgebildet, dass sie bei einer entsprechenden Belastung im Wesentlichen ohne Beschädigung des Streifenfundamentes 6 im Bereich der Stelle 25 oder über dieser knicken.The collecting device 1 consists of a plurality of vertical posts 2, which are each anchored with anchoring means V on a strip foundation 6. The anchoring means each have four anchoring bolts 10 with which a plate 9 is fastened over a strip foundation 6. Also conceivable here is a design in which the anchoring plates 9 rest on the strip foundation 6. In the FIG. 1 In this case, the lower nuts 12 are omitted and the plate 9 with the nuts 11 stretched on the foundation 6. On the plates 9, a stiffening element 8 is fixed in each case, for example, welded to the lower edge of the plate 9, which is triangular as shown and projects upwards. With two spaced-apart plates 24, the stiffening elements 8 are each welded to a post 2. An outer edge 7 of the stiffening element 8 approaches according to FIG. 1 continuously the post 2 and ends at an upper point 25, at which also the upper plate 24 ends. At this point 25 so that a kink is formed at which the post 2 buckle at a correspondingly high load. The posts 2 are formed so that they buckle at a corresponding load substantially without damaging the strip foundation 6 in the area of the point 25 or over this.

Die Pfosten 2 sind mit mehreren sich horizontal erstreckenden und ineinander gesteckten Längsprofilen 3 miteinander verbunden, die im Abstand zueinander übereinander angeordnet sind. Die Längsprofile 3 besitzen jeweils gemäss Figur 3 einen Längsschlitz 26, der zur Befestigung des Längsprofils 3 an einem Pfosten 2 mit einer Platte 19 hinterlegt ist, welche mit einer Schraube 20 am Pfosten 2 angeschraubt ist. Mittels weiteren Schrauben 27 sind die einzelnen Stücke des Längsprofils 3 miteinander verschraubt.The posts 2 are connected to each other with a plurality of horizontally extending and nested longitudinal profiles 3, which are arranged one above the other at a distance from each other. The longitudinal profiles 3 each according to FIG. 3 a longitudinal slot 26 which is deposited for attachment of the longitudinal profile 3 to a post 2 with a plate 19 which is screwed with a screw 20 on the post 2. By means of further screws 27, the individual pieces of the longitudinal profile 3 are screwed together.

Zwischen den Längsprofilen 3 sind Gitterelemente 4 fest mit jeweils benachbarten Pfosten 2 verbunden. Die Verbindung erfolgt mit Schrauben 28, welche die Gitter 4 durchgreifen. Die massiven Gitter mit folgenden Mindestmassen sind:

  • Länge = 1980 mm
  • Höhe = 380 mm
  • Tiefe = 40 mm
Between the longitudinal profiles 3 grid elements 4 are fixedly connected to each adjacent posts 2. The connection is made with screws 28 which pass through the grid 4. The massive grids with the following minimum masses are:
  • Length = 1980 mm
  • Height = 380 mm
  • Depth = 40 mm

Die Gitter 4 weisen zudem jeweils eine Randeinfassung und Querstäbe auf. Die Gitter 4 bilden zudem einen Blendschutz. Wie die Figur 1 zeigt, sind zudem unterhalb des untersten Längsprofils 3a zwei weitere Gitter 4 angeordnet.The grids 4 also each have an edge border and transverse bars. The grids 4 also form a glare shield. As the FIG. 1 shows, two more grids 4 are also below the bottom longitudinal profile 3a arranged.

Ist ein Schallschutz gewünscht, so wird die Auffangvorrichtung 1 mit einem Lärmschutzteil 5 versehen, der aus mehreren Lärmschutzteilen 5a zu einer Wand zusammengesetzt sind. Die Lärmschutzelemente 5a weisen zu ihrer Verbindung an Schmalseiten jeweils eine Feder 29 auf, die in eine entsprechende Schwalbenschwanznut eingesetzt ist. Das Lärmschutzteil 5 ist gemäss Figur 3 mit Schrauben 30 an den Längsprofilen 3 angeschraubt. Der Lärmschutzteil 5 besitzt gemäss Figur 2 eine Aufprallseite A, die der Fahrbahn 16 zugewandt ist. Die Lärmschutzteile 5a sind aus vergleichsweise dünnem Aluminiumblech hergestellt, sodass die Lärmschutzwand 5 bei einem Aufprall leicht verformt wird. Die weiter unten erwähnten Verbindungspfosten 21 bestehen vorzugsweise aus 4 mm starkem Stahlblech. Ist der Lärmschutzteil 5 nicht vorgesehen, so bilden die Längsprofile 3 sowie die Gitter 4 die Aufprallseite A. Das Fahrzeug bzw. die Last gleitet dann entlang den Längsprofilen 3 und gegebenenfalls entlang der Gitter 4, die vergleichsweise stabil ausgebildet sind. Die Gitter 4 können somit von einer Last bzw. einem Fahrzeug nicht ohne weiteres durchbrochen werden. Die Auffangvorrichtung 1 ist jedoch eine grundsätzlich vergleichsweise nachgiebige Konstruktion, die aber gleichzeitig die auftretenden Kräfte in Form von Zug-, Biege-, Druck- und Torsionsbeanspruchungen aufnehmen kann. Ohne das Lärmschutzteil 5 ist die Auffangvorrichtung nur bei vertikaler Ansicht durchsichtig und bildet einen Irritationsschutz beispielsweise gegen Scheinwerferlicht.If sound insulation is desired, the collecting device 1 is provided with a noise protection part 5, which are composed of several noise protection parts 5a to form a wall. The noise protection elements 5a have their connection on narrow sides in each case a spring 29 which is inserted into a corresponding dovetail groove. The noise protection part 5 is according to FIG. 3 screwed with screws 30 to the longitudinal profiles 3. The noise protection part 5 has according FIG. 2 an impact side A, which faces the roadway 16. The noise protection parts 5a are made of comparatively thin aluminum sheet, so that the noise protection wall 5 is easily deformed in an impact. The connecting posts 21 mentioned below are preferably made of 4 mm thick sheet steel. If the noise protection part 5 is not provided, the longitudinal profiles 3 and the lattices 4 form the impact side A. The vehicle or the load then slides along the longitudinal profiles 3 and optionally along the lattices 4, which are of comparatively stable design. The grids 4 can thus not without a load or a vehicle further break through. However, the collecting device 1 is a basically comparatively compliant construction, but at the same time can absorb the forces occurring in the form of tensile, bending, compressive and torsional stresses. Without the noise protection part 5, the collecting device is transparent only when viewed vertically and forms an anti-irritant, for example, against spotlight.

Die Pfosten 2 sind Doppelpfosten, die gemäss Figur 6 aus zwei im Querschnitt C-förmigen Profilen bestehen, die im Abstand zueinander angeordnet sind. Die Profile sind insbesondere sogenannte C 125-Profile. Dies gilt ähnlich für Verbindungspfosten 21, die gemäss den Figuren 4 und 5 aus jeweils zwei U-Profilen 21a bestehen. Die Schallschutzelemente 5a sind von oben in diese U-Profile 21a eingesetzt.The posts 2 are double posts, according to FIG. 6 consist of two cross-sectionally C-shaped profiles, which are arranged at a distance to each other. The profiles are in particular so-called C 125 profiles. This applies similarly to connection posts 21, which according to the FIGS. 4 and 5 consist of two U-profiles 21a. The soundproofing elements 5a are inserted from above into these U-profiles 21a.

Die Auffangvorrichtung 1 tritt lediglich dann in Wirkung, wenn die Gefahr eines Ladungsabwurfes mit grosser Wahrscheinlichkeit gegeben ist. Bei der Mehrzahl der Unfälle ist lediglich die Fahrzeugrückhaltevorrichtung 13 betroffen, die gemäss Figur 2 seitlich vor der Auffangvorrichtung 1 angeordnet ist. Diese Fahrzeugrückhalteeinrichtung 13 ist an sich bekannt und weisen beispielsweise Längselemente 15 auf, die an Pfosten 14 befestigt sind.The collecting device 1 only comes into effect when the risk of a charge discharge is given with great likelihood. In the majority of accidents, only the vehicle restraint device 13 is concerned, according to FIG. 2 is arranged laterally in front of the collecting device 1. This vehicle restraint device 13 is known per se and has, for example, longitudinal elements 15 which are fastened to posts 14.

Die Figur 8 zeigt eine Anordnung, die ebenfalls eine Fahrzeugrückhaltevorrichtung 13 sowie eine Auffangvorrichtung 1' nach einer Variante aufweist. Die Auffangvorrichtung 1' ist auf einer Bauwerkskappe 30 und wie ersichtlich im Querschnitt L-förmig und mit U-förmigen Armierungseisen 32 fest auf einer Brücke 31 angeordnet. Weiter Armierungseisen 33 verstärken die Bauwerkskappe 30. Auf einem verdicktem Bereich 30a der Bauwerkskappe 30a ist eine Verankerungsplatte 34 mit vier Verankerungsbolzen 35 verankert, wobei die Verankerungsplatte 34 auf der Bauwerkskappe 30 aufliegt. Die Verankerungsplatte 34 ist mit einem Versteifungselement 36 verschweisst, an dem wiederum ein Pfosten 37 angeschweisst ist. Im Fall eines Aufpralls über dem Versteifungselement 36 werden die Pfosten 37 jeweils im Bereich 38 geknickt, sodass dieser Bereich 38, der unmittelbar über dem Versteifungselement 36 liegt, eine Knickstelle bildet. Unterhalb der Knickstelle 38 ist an den Pfosten 37 ein fünftes Längsprofil 39 befestigt, das sich etwa in der Höhe der Fahrzeugrückhaltevorrichtung 13 befindet und damit die Auffangvorrichtung 1' im unteren Bereich verstärkt. Dadurch kann die Auffangvorrichtung 1' als weitere Fahrzeugrückhaltevorrichtung dienen, wenn die Fahrzeugrückhaltevorrichtung 13 von einem Fahrzeug durchbrochen wird.The FIG. 8 shows an arrangement which also has a vehicle restraint device 13 and a collecting device 1 'according to a variant. The collecting device 1 'is on a building cap 30 and as shown in cross-section L-shaped and arranged with U-shaped reinforcing bars 32 fixed on a bridge 31. Rein reinforcing bars 33 reinforce the building cap 30. On a thickened portion 30 a of the building cap 30 a is an anchoring plate 34 with four anchoring bolts 35th anchored, wherein the anchoring plate 34 rests on the building cap 30. The anchoring plate 34 is welded to a stiffening element 36, to which in turn a post 37 is welded. In the event of an impact over the stiffening element 36, the posts 37 are each bent in the region 38, so that this region 38, which lies directly above the stiffening element 36, forms a kink. Below the kink point 38, a fifth longitudinal profile 39 is attached to the posts 37, which is located approximately at the level of the vehicle restraint device 13 and thus reinforces the catching device 1 'in the lower region. As a result, the collecting device 1 'can serve as a further vehicle restraint device when the vehicle restraint device 13 is broken by a vehicle.

Die Figur 9 zeigt eine Auffangvorrichtung 1' ' , die sich von der Auffangvorrichtung 1' dadurch unterscheidet, dass eine obere Verankerungsplatte 40, die mit dem Verstärkungselement 36 verschweisst ist, auf eine untere Verankerungsplatte 42 gestellt ist. Mit Verankerungsbolzen 41 ist die untere Platte 42 fest mit der Bauwerkskappe 30 verbunden. Mit Verbindungsschrauben 43, die jeweils eine Sollbruchstelle besitzen, ist die obere Verankerungsplatte 40 mit der unteren Verankerungsplatte 42 verbunden. Bei einem Aufprall eines Fahrzeuges an der Auffangvorrichtung brechen beim Überschreiten einer vorbestimmten Kraft die Verbindungsschrauben 43 und die Verankerungsplatte 40 löst sich von der unteren Verankerungsplatte 42, ohne dass hierbei die Verankerungsbolzen 41 und die Bauwerkskappe 30 beschädigt werden. Ebenfalls können die Pfosten 37 im Bereich 38 knicken.The FIG. 9 1 shows a collecting device 1 "that differs from the collecting device 1 'in that an upper anchoring plate 40, which is welded to the reinforcing element 36, is placed on a lower anchoring plate 42. With anchoring bolts 41, the lower plate 42 is fixedly connected to the building cap 30. With connecting screws 43, each having a predetermined breaking point, the upper anchoring plate 40 is connected to the lower anchoring plate 42. In a collision of a vehicle on the collecting device break when connecting a predetermined force, the connecting bolts 43 and the anchoring plate 40 releases from the lower anchoring plate 42 without this the anchoring bolts 41 and the building cap 30 are damaged. Also, the posts 37 may bend in the area 38.
