Abstract

The present invention describes a protective beam arrangement, especially a protective beam arrangement for local reinforcement of standard crash barrier constructions. The protective beam arrangement consists of a crash barrier supported by stanchions, which is connected with the stanchions via a deformation element and a lower longitudinal stringer. Another upper longitudinal stringer is provided in addition to this lower longitudinal stringer, with supporting sections at the ends that are inclined downwards towards ground anchor points and which are supported by these anchor points embedded in the ground. The deformation element is made from a straight circular pipe that is arranged essentially vertically. The side clearance of the stanchions lies in the range between 1.3 to 2 m, preferably 1.4 m.

Description

Die Erfindung betrifft eine Schutzplankenanordnung, insbesondere Stahlschutzplankenanordnung.The invention relates to a guardrail arrangement, in particular steel guardrail arrangement.

Eine derartige Schutzplankenanordnung soll zur bereichsweisen Verstärkung von Standard-Leitplankenkonstruktionen, wie z. B. an Brücken bzw. Böschungen oder einsturzgefährdeten Tragwerken herangezogen werden.Such a guardrail arrangement is intended for areas Reinforcement of standard guardrail constructions, such as B. on bridges or embankments or structures that are at risk of collapse.

Aus der DE 4224998 ist beispielsweise eine Schutzplankenanordnung für Fahrbahnen bekannt (siehe Fig. 6a), die aus im Boden verankerten Ständern 2 besteht, an die fahrbahnseitig Deformationsprofile 3 befestigt sind, und an diese sowohl ein oberer Längsholm 4 als auch ein unterer Längsholm 5 angebracht sind. Ferner ist am unteren Längsholm 5 fahrbahnseitig eine Leitplanke 6 befestigt. Die Stirnseite der Leitplanke 6 steht über die Stirnseite des oberen Längsholms 4 horizontal vor. Zusätzlich weist das Deformationsprofil 3 am oberen Ende einen versteifenden Quersteg 11 auf. Wie in den weiteren Figuren 6b und 6c gezeigt, wird bei einem Aufprall, beispielsweise durch ein Fahrzeug, die Schutzplankenanordnung derart deformiert, daß zunächst das Deformationsprofil 3 am unteren Ende 18 eingedrückt wird, ohne daß der dahinterliegende Ständer in Mitleidenschaft gezogen wird. Wird darüber hinaus aufgrund des Aufpralls das Deformationsprofil 3 im unteren Bereich 18 vollständig eingedrückt, so geht die Krafteinwirkung auf den dahinter liegenden Ständer 2 über. In dieser Stellung liegen die Stirnseite der Leitplanke 6 und die Stirnseite des oberen Längsholms 4 nahezu in einer Ebene (siehe Bezugszeichen VE in Fig. 6c). DE 4224998 is, for example, a guardrail arrangement known for roadways (see Fig. 6a), which consists of stands 2 anchored in the ground deformation profiles 3 are fastened on the carriageway side, and to this both an upper longitudinal beam 4 and a lower longitudinal spar 5 are attached. It is also at the bottom A guardrail 6 is attached to the longitudinal spar 5 on the roadway side. The front side of the guardrail 6 is above the Front of the upper longitudinal spar 4 horizontally in front. In addition has the deformation profile 3 at the upper end a stiffening crossbar 11. As in the others FIGS. 6b and 6c, is shown in the event of an impact, for example by a vehicle, the guardrail arrangement deformed in such a way that initially the deformation profile 3 is pushed in at the lower end 18 without that the stand behind it was affected becomes. Furthermore, due to the impact the deformation profile 3 in the lower region 18 completely pressed in, the force is applied the stand 2 behind it. In this position are the front side of the guardrail 6 and the Front of the upper longitudinal spar 4 almost in one Level (see reference symbol VE in Fig. 6c).

Derartige bekannte Schutzplankenanordnungen sind insbesondere dafür gedacht, ein Überschreiten des Fahrbahnrandes eines vom Wege abgekommenen Fahrzeuges zu unterbinden. Jedoch sind herkömmliche Standard-Leitplankenkonstruktionen lediglich dafür ausgelegt, eine Fahrbahnrandsicherung bereitzustellen. Hierbei kann es allerdings vorkommen, daß bei höheren Aufprallenergien die Schutzwirkung der Standard-Leitplankenanordnung nicht ausreicht, um das Fahrzeug von einem Überschreiten des Fahrbahnrandes zurückzuhalten. Ein Überschreiten des Fahrbahnrandes ist solange unproblematisch, solange keine besonderen Streckenabschnitte, wie beispielsweise Böschungen, einsturzgefährdete Tragwerke oder aber auch Brückenkonstruktionen durch die Schutzplankenanordnung abzusichern sind. In diesen besonderen Fällen wäre es allerdings von Vorteil, wenn herkömmliche Standard-Leitplankenanordungen bereichsweise verstärkt werden könnten. Zusätzlich wäre es von Vorteil, wenn die neuerdings strengeren europäischen Sicherheitsstandards für Rückhaltesysteme an Straßen ebenfalls Beachtung finden könnten. Eine derartige bereichsweise zur Verstärkung von Standard-Leitplankenkonstruktionen herangezogene Schutzplankenanordnung müßte außerdem dergestalt sein, daß die zu verstärkende Leitplankenkonstruktion nicht konstruktiv umgestaltet werden muß.Such known guardrail arrangements are in particular intended to cross the edge of the road to prevent a vehicle that has lost its way. However, conventional are standard guardrail designs only designed to secure the road edge to provide. However, it can occur that at higher impact energies the protective effect of the standard guardrail arrangement not sufficient to prevent the vehicle from being exceeded restrain the edge of the road. Exceeding the edge of the road is unproblematic as long as as long as no special sections, such as For example, embankments, structures at risk of collapse or also bridge structures through the guardrail arrangement are to be secured. In this particular one In cases, however, it would be an advantage if conventional Standard guardrail arrangements reinforced in some areas could become. It would also be an advantage if the recently stricter European security standards for restraint systems on roads as well Could get attention. Such an area to reinforce standard guardrail constructions Guardrail arrangement used should also be such that the one to be reinforced Guardrail construction not redesigned must become.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Schutzplankenanordnung für Fahrbahnen zur bereichsweisen Verstärkung von Standard-Leitplankenkonstruktionen zu schaffen, die einen einfachen einwandfreien Übergang zu Standard-Leitplankenkonstruktionen gewährleistet, eine einfache Handhabung beim Austausch von deformierten Komponenten nach einem Aufprall ermöglicht und den strengen europäischen Sicherheitsstandards entspricht.It is therefore an object of the present invention to Guardrail arrangement for lanes for areas Reinforcement of standard guardrail designs to create a simple flawless Transition to standard guardrail designs ensures easy handling when replacing deformed components after a Impact allows and the strict European Meets security standards.

Diese Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of the claim 1 solved.

Die erfindungsgemäße Schutzplankenanordnung für Fahrbahnen zur bereichsweisen Verstärkung von Standard-Leitplankenkonstruktionen weist einen oberen und unteren Längsholm auf, die direkt an dem zumindest einen Ständer befestigt sind. An dem oberen Längsholm ist endseitig jeweils ein nach unten zu einer Bodenverankerung laufendes Stützprofil vorgesehen. Der untere Längsholm schließt endseitig mit dem schräg nach unten laufenden Stützprofil bündig ab. Zwischen dem unteren Längsholm und der Leitplanke ist ein Deformationselement in Form eines geraden Kreisrohrs vorgesehen, dessen Achse im wesentlichen vertikal ausgerichtet ist. Der Seitenabstand der Ständer ist erfindungsgemäß im Bereich zwischen 1,3 und 2 m, vorzugsweise bis zu 1,40 m, insbesondere 1,33 m, festgelegt. Mit dieser Konstruktion der Schutzplankenanordnung wird erreicht, daß Standard-Leitplankenkonstruktionen bereichsweise verstärkt werden, und zwar derart, daß die nach europäischen Normen festgesetzte Anprallschwerestufe ("impact severity level") A auf einfache Weise erreicht werden kann, insbesondere wird der ASI-Wert von ≤ 1,0 erreicht. Mit der erfindungsgemäßen Schutzplankenanordnung wird durch gegenseitiges Abstützen die Gesamtkonstruktion stabiler, wobei insbesondere durch den den ASI-Wert beeinflussenden Seitenabstand der Ständer im Bereich zwischen 1,3 und 1,4 m der ASI-Wert von ≤ 1 erfüllt wird. Dadurch, daß die Leitplanke zusätzlich um den Durchmesser des Deformationselementes von dem oberen Längsholm vorsteht, erfolgt innerhalb bestimmter Anprallenergie eine Deformation der Schutzplankenanordnung lediglich an der Leitplanke selbst und an dem Deformationselement. Auf diese Weise kann der Austausch der beschädigten Komponenten, insbesondere des Deformationselementes und der Leitplanke einfacher erfolgen. Dadurch daß das Deformationselement lediglich an einem Längsholm vorgesehen ist, und sich nicht - wie im Stand der Technik - über zwei Längsholme erstreckt, wird materialsparender gearbeitet, wobei gleichzeitig die Passgenauigkeit beim Aufstellen der Schutzplankenanordnung erhöht wird. Dadurch wird die Handhabung der gesamten Schutzplankenanordnung vereinfacht. Da die Leitplanke um ihre Tiefe und dem Durchmesser des Deformationselementes von dem oberen Längsholm vorsteht, erfolgt eine Kraftbeaufschlagung des oberen Längsholmes durch ein Fahrzeug mit im wesentlichen horizontal verlaufender Aufprallfläche erst dann, wenn das Deformationselement nahezu vollständig zusammengedrückt wird und der Ständer bereits um einen geringen Winkel geneigt wird. Es wird somit gewährleistet, daß die Kraftbeaufschlagung über einen großen Aufprallenergiebereich lediglich mit einem kleinen Hebel, der durch den Vertikalabstand des unteren Längsholmes zum Boden definiert ist, auf den Ständer einwirkt. Erst wenn das Deformationselement vollständig deformiert ist, kann die Kraftbeaufschlagung über den oberen Längsholm mit größerem Hebel erfolgen. Auf diese Weise können Ständer mit geringerem Widerstandsmoment als beim Stand der Technik verwendeten Ständern eingesetzt werden. Dadurch, daß das Deformationselement lediglich aus einem geraden Kreisrohr gebildet ist, wird der Herstellungsaufwand gering gehalten. Dadurch, daß sich erfindungsgemäß der obere Längsholm über ein schräg nach unten verlaufendes Stützprofil an einem Bodenanker abgestützt ist, wird erreicht, daß nicht lediglich eine Stabilisierung der Leitplanke über die Ständer erfolgt, sondern auch eine Stabilisierung in Form einer Zugspannung innerhalb des oberen Längsholmes und des Stützprofils auftritt, die der Kraftbeaufschlagung entgegenwirken.The guard rail arrangement for carriageways according to the invention for area-wise reinforcement of standard guardrail constructions has an upper and lower Longitudinal spar on that directly on the at least one Stand are attached. At the upper longitudinal spar is at the ends one down to a floor anchor ongoing support profile provided. The lower Longitudinal bar closes at the end with the sloping downward running support profile flush. Between the bottom Longitudinal spar and the guardrail is a deformation element provided in the form of a straight circular tube, the Axis is oriented substantially vertically. The side spacing of the stands is according to the invention in Range between 1.3 and 2 m, preferably up to 1.40 m, in particular 1.33 m. With this construction the guardrail arrangement ensures that Standard guardrail constructions reinforced in some areas in such a way that the European Impact severity level ("impact severity level ") A can be easily achieved can, in particular the ASI value of ≤ 1.0 is reached. With the guardrail arrangement according to the invention the entire construction is supported by one another more stable, in particular by the ASI value-influencing side distance of the stand in the Range between 1.3 and 1.4 m the ASI value of ≤ 1 is met becomes. The fact that the guardrail in addition the diameter of the deformation element from that protrudes the upper longitudinal spar, takes place within certain Impact energy a deformation of the guardrail arrangement only on the guardrail itself and on the deformation element. This way, the exchange the damaged components, especially the deformation element and the guardrail is easier to do. Characterized in that the deformation element only on one Longitudinal spar is provided, and not - as in the state technology - spreading over two longitudinal spars becomes more material-saving worked, at the same time the Precise fit when setting up the guardrail arrangement is increased. This will handle the whole Barrier arrangement simplified. Because the guardrail about their depth and the diameter of the deformation element protrudes from the upper longitudinal spar a force applied to the upper longitudinal spar by a vehicle with a substantially horizontal Impact surface only when the deformation element is almost completely compressed and the stand is already tilted at a slight angle becomes. It is thus ensured that the application of force over a large impact energy range only with a small lever, which is due to the vertical distance of the lower longitudinal spar to the floor is acting on the stand. Only when the deformation element is completely deformed, the Force application over the upper longitudinal spar with a larger one Lever. This way, stands with a lower section modulus than at the state of the Technology used stands are used. Thereby, that the deformation element consists only of one straight circular tube is formed, the manufacturing cost kept low. The fact that according to the invention the upper longitudinal spar sloping downwards running support profile supported on a ground anchor is achieved that not only stabilization the guardrail is done via the stand, but also stabilization in the form of tension within the upper longitudinal bar and the support profile occurs that counteract the application of force.

Die Leitplanke ist gemäß Anspruch 2 rückseitig über einen Stützbügel befestigt. Dadurch können die äußeren Schenkel der Leitplanke abgestützt werden, um die Steifigkeit der Leitplanke an sich zu erhöhen. Dies führt ebenso zu einer Materialeinsparung hinsichtlich der Leitplanke.The guardrail is at the rear via a Support bracket attached. This allows the outside Legs of the guardrail are supported for rigidity to raise the guardrail itself. this leads to also to a material saving in terms of Guardrail.

Es hat sich gezeigt, daß gemäß Anspruch 4 die Schutzplankenanordnung durch Ständer mit C-Querschnittsprofil auf einfache Weise realisiert werden, wobei an einem Schenkel des C-Querschnittsprofils der untere und obere Längsholm mit dem Ständer verschraubt werden. Über die Schraubverbindung ist gewährleistet, daß der Austausch von oberem und unterem Längsholm einfach vollzogen werden kann. Um die europäischen Sicherheitsstandards zu erreichen, hat es sich als vorteilhaft erwiesen, daß die Schenkel des C-Profils gemäß Anspruch 5 parallel zueinander verlaufen und auf dem sich anschließenden Steg senkrecht stehen, wobei gemäß Anspruch 6 die Schenkel des C-Profils endseitig nach innen umgebogen sind.It has been shown that the guardrail arrangement according to claim 4 with stands with a C cross-sectional profile be realized in a simple manner, with one Leg of the C cross-sectional profile of the lower and upper Longitudinal spar are screwed to the stand. About the Screw connection ensures that the exchange can be easily carried out from the upper and lower longitudinal spars can. To meet European security standards achieve, it has proven advantageous that the legs of the C-profile according to claim 5 in parallel run to each other and on the subsequent one Bridge are vertical, the according to claim 6 The end of the leg of the C-profile is bent inwards are.

Um den Herstellungsaufwand gering zu halten, ist es von Vorteil, wenn der untere und/oder der obere Längsholm von einem Rechteckprofil, vorzugsweise handelsüblichem Rechteckprofil gebildet ist.To keep the manufacturing costs low, it is from Advantage if the lower and / or the upper longitudinal spar of a rectangular profile, preferably commercially available Rectangular profile is formed.

Um einer Materialeinsparung gerecht zu werden, wird das Rechteckprofil gemäß Anspruch 8 von einem geschlossenen Hohlprofil gebildet.In order to do justice to material savings, this will be Rectangular profile according to claim 8 of a closed Hollow profile formed.

Wird das Rechteckprofil gemäß Anspruch 9 von einem im Bereich einer Seitenwand offenen Profil gebildet, so kann eine Klemmverbindung zwischen dem Rechteckprofil und dem Ständer dadurch bereitgestellt werden, daß in der schlitzartigen Öffnung des Profils im wesentlichen mit Passung ein Führungs- und Distanzelement aufgenommen ist. Über die Klemmverbindung wird erreicht, daß ein einfaches Positionieren der Längsholme an dem Ständer ermöglicht wird und ein Austausch schnellstmöglich vorgenommen werden kann.If the rectangular profile according to claim 9 by one in Area of a side wall formed open profile, see above can create a clamp connection between the rectangular profile and provided to the stand by: the slot-like opening of the profile essentially fit a guide and spacer element is. What is achieved via the clamp connection is that easy positioning of the longitudinal bars on the stand is made possible and an exchange as soon as possible can be made.

Wird gemäß Anspruch 10 das Rechteckprofil mittels einer Druckplatte mit dem Ständer verbunden, so wird die Kraftübertragung erhöht, und insbesondere dann, wenn die Druckplatte kraftschlüssig mit dem Ständer verbunden ist.According to claim 10, the rectangular profile by means of a Pressure plate connected to the stand, so the Power transmission increases, and especially when the pressure plate is non-positively connected to the stand is.

Wie in Fig. 1 dargestellt ist, weist die erfindungsgemäße Schutzplankenanordnung 1 mindestens einen Ständer 3 auf, an dem ein oberer Längsholm 5 und ein unterer Längsholm 7 direkt befestigt sind, die vorzugsweise in Form eines Kastenprofils mit den Ausmaßen 150 * 180 mm ausgebildet sind. An dem unteren Längsholm 7 wird die Leit- bzw. Schutzplanke 9 über zumindest ein Deformationselement 11 befestigt. Die Deformationselemente 11 sind vorzugsweise in einer mit den Ständern 3 bildende Ebene angeordnet, die senkrecht zur Längsrichtung der Schutzplankenanordnung angeordnet ist. Es ist ebenso möglich, daß sowohl mehrere als auch wenigere Deformationselemente 11 in den Zwischenräumen benachbarter Ständer vorgesehen sind. Wie in Fig. 1 deutlich zu sehen ist, sind die vorzugsweise in Form eines C-Profils ausgebildeten Ständer 3 lediglich in den Boden gerammt.As shown in Fig. 1, the invention Guardrail assembly 1 at least one stand 3 on which an upper longitudinal beam 5 and a lower Longitudinal beam 7 are attached directly, which are preferably in Form of a box profile with the dimensions 150 * 180 mm are trained. On the lower longitudinal spar 7 Guardrail or guardrail 9 via at least one deformation element 11 attached. The deformation elements 11 are preferably in one with the stands 3 forming Arranged plane that is perpendicular to the longitudinal direction of the Guardrail arrangement is arranged. That `s how it is possible that both several and fewer deformation elements 11 in the spaces between neighboring Stands are provided. As clearly seen in Fig. 1 is preferably in the form of a C-profile trained stand 3 just rammed into the ground.

In Fig. 2 wird eine Seitenansicht der erfindungsgemäßen Schutzplankenanordnung 1 gezeigt. Hierin ist detaillierter dargestellt, daß der obere und untere Längsholm 5 und 7 eine schlitzartige Öffnung 31 aufweist und über eine Klemmverbindung mittels einer Druckplatte 13 und einem Distanzelement 15 mit dem Ständer verbunden ist, vorzugsweise über eine Schraubenkonstruktion SK verschraubt ist. Das Distanzelement 15 wird vorzugsweise passgenau in der schlitzartigen Öffnung 31 aufgenommen. 2 is a side view of the invention Guardrail assembly 1 shown. Herein is more detailed shown that the upper and lower longitudinal spar 5 and 7 has a slot-like opening 31 and over a clamp connection by means of a pressure plate 13 and a spacer 15 is connected to the stand, preferably screwed using a screw construction SK is. The spacer 15 is preferred fit in the slot-like opening 31.

Der untere und/oder obere Längsholm 5 und 7 wird mit einem Schenkel 17 des C-Profils des Ständers 3 verbunden. An dem unteren Längsholm 7 wird das Deformationselement 11 in Form eines Kreisrohres vorzugsweise über eine Schraubenkonstruktion SK befestigt. In dieser Ausführungsform gemäß Fig. 2 wird die Leitplanke 9 durch einen Stützbügel 21 an dem Deformationselement 11 befestigt, vorzugsweise angeschraubt. Um die europäischen Sicherheitsstandards zu erfüllen, hat es sich als vorteilhaft erwiesen, wenn der Ständer 3 als C-125-Profil vorzugsweise HS=1140 mm im wesentlichen senkrecht nach oben aus dem Boden Bd herausragt, wobei der Ständer 3 mindestens 1200 mm im Boden eingerammt sein muß. Bei der vorteilhaften Ausführungsform ist die Leitplanke 9 mit ihrer oberen Abschlußkante HL=750 mm vom Boden entfernt, wobei die Oberkante des Kastenprofils des oberen Längsholms 5 mit den Ausmaßen 150 * 180 mm HOL=1150 mm vom Boden beabstandet ist. Es ergibt sich somit eine Gesamtkonstruktion der erfindungsgemäßen Schutzplankenanordnung 1, bei der die horizontale Stirnfläche der Leitplanke 9 um ca. HS=380 mm vom Ständer 3 vorsteht. Für die Schraubenkonstruktion zwischen dem Deformationselement mit der Dimension ⊘ 139,7 mm * 4 mm und der Leitplanke 9 werden Sechskantschrauben M14 * 40 verwendet, wobei der obere und untere Längsholm 5 und 7 mit Sechskantschrauben M14 * 30 an dem Ständer 3 über eine Druckplatte 13 mit den Dimensionen 50 * 10 * 140 mm und einem Distanzelement 15 mit der Dimension 50 * 5 * 110 mm befestigt werden. Es sei jedoch hervorgehoben, daß die Gesamthöhe HS des Ständers 3 variabel gestaltet werden kann.The lower and / or upper longitudinal spar 5 and 7 is with a leg 17 of the C-profile of the stand 3 connected. The deformation element is on the lower longitudinal spar 7 11 preferably in the form of a circular tube attached via a screw construction SK. In this 2 is the guardrail 9 by means of a support bracket 21 on the deformation element 11 attached, preferably screwed. To the European It has to meet security standards proven to be advantageous if the stand 3 as a C-125 profile preferably HS = 1140 mm substantially perpendicular protrudes upwards from the floor Bd, the Stand 3 must be rammed into the ground at least 1200 mm got to. In the advantageous embodiment, the Guardrail 9 with its top edge HL = 750 mm from the floor, with the top edge of the box section of the upper longitudinal spar 5 with the dimensions 150 * 180 mm HOL = 1150 mm from the ground. It results thus an overall construction of the invention Guardrail arrangement 1, in which the horizontal Front surface of the guardrail 9 by approx. HS = 380 mm from the stand 3 stands out. For the screw construction between the deformation element with the dimension ⊘ 139.7 mm * 4 mm and the guardrail 9 become M14 hexagon bolts * 40 used, the upper and lower longitudinal spar 5 and 7 with M14 * 30 hexagon screws on the stand 3 via a pressure plate 13 with the dimensions 50 * 10 * 140 mm and a spacer 15 with dimension 50 * 5 * 110mm can be attached. However, it should be emphasized that the total height HS of the stand 3 is variable can be designed.

In Fig. 3a ist die Gesamtübersicht der erfindungsgemäßen Schutzplankenanordnung 1 dargestellt, wobei deutlich zu erkennen ist, daß endseitig zu dem oberen Längsholm 5 jeweils schräg nach unten laufende Stützprofile 23 vorgesehen sind, die wiederum endseitig mit in den Boden eingelassenen Konsolen 25 abgespannt sind. In dieser Darstellung wird deutlich, daß lediglich in dem mittleren Bereich der Schutzplankenanordnung 1 der obere Längsholm 5 zu dem unteren Längsholm 7 bzw. zu der Leitplanke 9 im Parallelabstand geführt ist. Es hat sich als vorteilhaft herausgestellt, daß die Konsole aus Beton gegossen wird, mit der Dimension 800 * 800 * 800 mm. Ferner ist in Fig. 3a eine Konstruktionsform der erfindungsgemäßen Schutzplankenanordnung gezeigt, bei der die Ständer 3 um 1333 mm zueinander beabstandet sind.3a is the overall overview of the invention Guardrail arrangement 1 shown, clearly it can be seen that the end of the upper Longitudinal beam 5 each support profiles running obliquely downwards 23 are provided, which in turn end with Consoles 25 embedded in the floor are braced. In this illustration it is clear that only in the middle area of the guardrail arrangement 1 of the upper longitudinal spar 5 to the lower longitudinal spar 7 or the guardrail 9 is guided at a parallel distance. It has turned out to be advantageous that the console is poured from concrete with the dimension 800 * 800 * 800 mm. 3a is a construction form shown the guardrail arrangement according to the invention, in which the stand 3 spaced apart by 1333 mm are.

In Fig. 3b ist eine Draufsicht der Schutzplankenanordnung 1 gezeigt, wobei deutlich zu erkennen ist, daß die Leitplanke 9 geradlinig ohne größere konstruktive Maßnahmen in den Bereich der Verstärkung gemäß der Schutzplankenanordnung hineingeführt und auch wieder herausgeführt werden kann. Ferner ist deutlich zu erkennen, daß die erfindungsgemäße Schutzplankenanordnung 1 auf der fahrbahnseitig abgewandten Seite der Leitplanke 9 angeordnet ist. Von daher wird kein Volumen der Fahrbahn an sich beansprucht. Auch wird in dieser Darstellung deutlich, daß die Ständer 3 zusätzlich zu der Befestigung des oberen Längsholmes lediglich dann benötigt werden, wenn das Stützprofil 23 auf der gleichen Höhe oder höher als die Leitplanke 9 angeordnet ist.3b is a top view of the guardrail assembly 1, wherein it can be clearly seen that the crash barrier 9 is straightforward without major constructive Measures in the area of reinforcement according to the Guardrail assembly introduced and again can be brought out. It can also be clearly seen that the guardrail arrangement according to the invention 1 on the side of the guardrail facing away from the carriageway 9 is arranged. Therefore, no volume the roadway itself. Also in this Representation clearly that the stand 3 in addition to the fastening of the upper longitudinal bar only then are needed if the support profile 23 on the same Height or higher than the guardrail 9 arranged is.

Fig. 4a zeigt im wesentlichen den Verlauf des Stützprofils 23 sowie dessen Verankerung mittels der Konsole 25 im Boden. In Fig. 4b ist diese Bodenverankerung detaillierter hervorgehoben. Man erkennt, daß in der Konsole 25 ein I-Profil 33 eingegossen ist, daß teilweise aus der Konsole 25 hervorsteht. Ferner ist am bodenseitigen Endabschluß des Stützprofils 23 ein Abspannelement 27 insbesondere für das Kastenprofil 150 * 180 mm vorgesehen, das ein Zugbolzen 29 trägt, das federnd über eine Unterlagscheibe US, beispielsweise in Form einer Tellerfeder, mit dem I-Profil abgestützt ist.4a essentially shows the course of the support profile 23 and its anchoring using the console 25 in the bottom. This ground anchorage is shown in more detail in FIG. 4b highlighted. You can see that in the console 25 an I-profile 33 is cast that partially protrudes from the console 25. Furthermore, is on the bottom side End of the support profile 23 a guy element 27 especially for box section 150 * Provided 180 mm, which carries a tie bolt 29, the resilient via a washer US, for example in Shape of a disc spring, supported with the I-profile is.

In Fig. 5a ist eine Frontansicht des mittleren Bereiches der erfindungsgemäßen Schutzplankenanordnung 1 gezeigt, sowie eine Draufsicht in Fig. 5b. Hierbei sei hervorgehoben, daß wie in Fig. 5b dargestellt, die einzelnen Ständer 3 um PA=1333 mm beabstandet sind und die Übergangsstelle ÜS der einzelnen oberen Längsholme 5 mit einer Länge von LO=4000 mm im wesentlichen mittig zu den Ständern 3 angeordnet ist. Ferner wird aus den Fig. 5a und 5b deutlich, daß die Übergangsstellen ÜL der Leitplanken 9 zueinander an den Deformationselementen vorgesehen ist. Mit der erfindungsgemäßen Schutzplankenanordnung 1, insbesondere mit den oben aufgeführten Bemaßungen, wurde erreicht, daß die europäische Anforderungsklasse bzw. Anprallschwereklasse H2 erfüllt wurde. Für die Beurteilung der Anprallschwere ließ man einen 900 kg schweren Personenwagen unter einem Winkel von 20° und einer Geschwindigkeit von 103 km/h an die Schutzplankenanordnung anprallen. Wie erwartet, vernichteten die Deformationselemente einen großen Anteil der Anprallenergie. Während der gesamten Umlenkungsphase nahm das Fahrzeug zu keinem Zeitpunkt einen kritischen dynamischen Zustand ein. Trotz der geringen Nachgiebigkeit der Schutzplankenanordnung, was unter anderem an dem äußerst kleinen Systemschaden zu erkennen war, lag der ASI-Wert von ≤ 1,0 noch im zulässigen Bereich der Anprallschwerestufe A. Es zeigte sich, daß sich bei einem weiteren Versuch, bei dem ein 13 Tonnen schwerer Bus unter einem Winkel von 20° und einer Geschwindigkeit von 71 km/h auf die Schutzplankenanordnung prallte, eine maximale dynamische Querverschiebung von lediglich 0,78 m auftrat und lediglich eine bleibende Durchbiegung von 0,6 m aufwies.5a is a front view of the central area the guardrail arrangement 1 according to the invention shown, as well as a plan view in Fig. 5b. Here is emphasized that, as shown in Fig. 5b, the individual Stand 3 are spaced by PA = 1333 mm and the Transition point ÜS of the individual upper longitudinal spars 5 with a length of LO = 4000 mm essentially in the middle is arranged to the stand 3. Furthermore, the 5a and 5b clearly that the transition points ÜL the crash barriers 9 to each other on the deformation elements is provided. With the guardrail arrangement according to the invention 1, especially those listed above Dimensions, it was achieved that the European Requirement class or impact severity class H2 met has been. For the assessment of the severity of the collision was left a 900 kg passenger car at an angle of 20 ° and a speed of 103 km / h to the Impact the crash barrier arrangement. As expected, annihilated the deformation elements make up a large proportion impact energy. During the entire redirection phase the vehicle never took one critical dynamic state. Despite the small Compliance of the guardrail arrangement what among other things due to the extremely small system damage was recognizable, the ASI value of ≤ 1.0 was still within the permissible range Area of impact severity level A. It showed that another attempt, in which a 13 ton bus at an angle of 20 ° and a speed of 71 km / h on the guardrail arrangement bounced, a maximum dynamic transverse displacement of only 0.78 m occurred and only showed a permanent deflection of 0.6 m.

Aufgrund dieser Daten kann davon ausgegangen werden, daß die Schutzplankenanordnung als Absturzsicherung, zur Sicherung von einsturzgefährdeten Konstruktionen oder Bauwerken oder als doppelseitige Ausführung bei schmalen Mittelstreifen geeignet ist. Aufgrund der Bauweise der Schutzplankenanordnung kann in fachtechnisch einwandfreier Art und Weise ein Anschluß zu bekannten Standardkonstruktionen von Schutzanordnungen problemlos bewerktstelligt werden.Based on this data, it can be assumed that the guardrail arrangement as fall protection, to secure structures at risk of collapse or structures or as a double-sided version narrow median strip is suitable. Because of the design The guardrail arrangement can be technically flawless way a connection to known Standard designs of protective arrangements without problems be valued.
