Description

Die Erfindung betrifft einen Schutzplankenstrang aus Stahl gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to a protective barrier of steel according to the features in the preamble of claim 1.

Ein derartiger Schutzplankenstrang zählt z. B. im Umfang der EP 1061179 A1 zum Stand der Technik. Er besteht aus lösbar aneinander gesetzten Schutzplanken mit einem im Wesentlichen W-förmigen Querschnitt. Die Schutzplanken werden von Pfosten getragen, die in das Erdreich gerammt sind. Der W-förmige Querschnitt wird von einem zentralen Boden, von dem Boden aus divergierenden Innenschenkeln, von endseitig der Innenschenkel vorgesehenen bogenförmigen Übergangsabschnitten und von sich an die Übergangsabschnitte anschließenden, sich gegensinnig V-förmig zu den Innenschenkeln erstreckenden Außenschenkeln gebildet. Die Außenschenkel enden etwa in einer Ebene, in der auch der Boden verläuft.Such a protective barrier strand counts z. B. in the scope of EP 1061179 A1 to the state of the art. It consists of releasably juxtaposed guard rails with a substantially W-shaped cross-section. The guardrails are carried by posts that have rammed into the ground. The W-shaped cross-section is formed by a central bottom, by the bottom of diverging inner legs, provided by the end of the inner leg arcuate transition sections and adjoining the transition sections, in opposite directions V-shaped to the inner legs extending outer legs. The outer thighs end approximately in a plane in which the floor runs.

Schutzplankenstränge mit der vorbeschriebenen Ausbildung werden u.a. sowohl an den Rändern von Kraftfahrzeugstraßen, wie z.B. Autobahnen, als auch auf den Mittelstreifen solcher Kraftfahrzeugstraßen angeordnet. Hierbei verlangen die gesetzlichen Richtlinien bislang, dass diese Schutzplankenstränge den Anforderungen einer sogenannten Aufhaltestufe H1 mit einem bestimmten Aufhaltevermögen genügen müssen. Übergeordnete europäische Richtlinien verlangen jedoch in der Zukunft generell die Aufhaltestufe H2. Den hiermit verbundenen höheren Anforderungen an das Aufhaltevermögen werden die zum Stand der Technik zählenden Schutzplankenstränge dann nicht mehr gerecht.Safety barrier strands with the above-described training, inter alia, both at the edges of motor vehicle roads, such as highways, as also arranged on the median strip of such motor vehicle roads. So far, the legal guidelines require that these protective barrier strands must meet the requirements of a so-called containment level H1 with a certain retention capacity. However, higher-level European directives generally require the containment stage H2 in the future. The higher demands on the retention capacity associated therewith are no longer sufficient for the protective plank strands belonging to the state of the art.

Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zu Grunde, einen Schutzplankenstrang bereit zu stellen, der nicht nur den erhöhten Anforderungen der Aufhaltestufe H2 hinsichtlich des Aufhaltevermögens genügt, sondern auch mit denjenigen Schutzplankensträngen kompatibel ist, die unter die Aufhaltestufe H1 fallen.The invention is - based on the prior art - the object to provide a protective barrier that not only meets the increased requirements of the containment level H2 in terms of containment, but is also compatible with those guard rail strands that fall under the containment level H1.

Die Lösung dieser Aufgabe besteht nach der Erfindung in den Merkmalen des Anspruchs 1.The solution to this problem consists according to the invention in the features of claim 1.

Danach erhalten jetzt die Außenschenkel an ihren Enden vom Boden der Schutzplanke weg gerichtete Versteifungsstege, an die sich annähernd in Richtung der Außenschenkel erstreckende Schenkelfortsätze anschließen. Aufgrund der Versteifungsstege und der Schenkelfortsätze besitzt die erfindungsgemäße Schutzplanke ein höheres Widerstandsmoment, und zwar in X-, in Y- als auch in Z-Richtung. Die Verwindungssteifigkeit der Schutzplanke wird deutlich verbessert, so dass sie bei problemloser Kompatibilität mit den herkömmlichen Schutzplanken nunmehr den erhöhten Anforderungen der Aufhaltestufe H2 in Bezug auf das Aufhaltevermögen genügt. Variationsmöglichkeiten bestehen hierbei in der Ausbildung der Breite der Versteifungsstege und/oder der Breite der Schenkelfortsätze. Ferner kann durch den Grad der Abwinklung der Versteifungsstege zu den Außenschenkeln und/oder zu den Schenkelfortsätzen das geforderte Aufhaltevermögen der Schutzplanke gezielt eingestellt werden.Thereafter, the outer legs now receive stiffening webs directed away from the floor of the protective barrier at their ends, to which leg extensions extend approximately in the direction of the outer legs. Due to the stiffening webs and the leg extensions, the protective barrier according to the invention has a higher resistance moment, in the X, Y and Z directions. The torsional stiffness of the guardrail is significantly improved, so that it complies with the increased requirements of the containment level H2 in terms of containment with easy compatibility with the conventional crash barriers now. Variations exist here in the formation of the width of the stiffening webs and / or the width of the leg extensions. Furthermore, by the degree of bending of the stiffening webs to the outer legs and / or to the leg extensions, the required holding capacity of the guardrail can be adjusted specifically.

Ein weiterer wesentlicher Vorteil der Erfindung besteht darin, dass durch die gezielte Ausbildung der Schutzplanke mit den Versteifungsstegen und den Schenkelfortsätzen die Stapelfähigkeit wie bei den bekannten Schutzplanken erhalten bleibt. Dies erleichtert nicht nur eine Platz sparende Lagerhaltung, sondern auch den Transport vom Lager zu den Montagestellen an den Fahrbahnen.Another essential advantage of the invention is that the stackability is maintained as in the known protective barriers by the targeted training of the guardrail with the stiffening webs and the leg extensions. This not only facilitates a space-saving storage, but also the transport from the warehouse to the mounting points on the lanes.

Dieser Vorteil wird unabhängig davon erreicht, ob es sich um einen Schutzplankenstrang mit sogenannten A-Planken, d.h. fahrbahnseitig gerundeten Übergangsabschnitten (Kuppen) zwischen den Innenschenkeln und den Außenschenkeln, oder um einen Schutzplankenstrang mit B-Planken, also mit fahrbahnseitig ebenen Übergangsabschnitten zwischen den Innenschenkeln und den Außenschenkeln handelt.This advantage is achieved regardless of whether it is a protective barrier with so-called A-planks, i. Roadway rounded transition sections (crests) between the inner legs and the outer legs, or is a guard rail with B-planks, ie with roadway-level transitional sections between the inner thighs and the outer thighs.

Des Weiteren kann die Erfindung bei einseitig von Pfosten angeordneten oder auf beiden Seiten von Pfosten vorgesehenen Schutzplankensträngen angewendet werden und ferner auch unabhängig davon, ob die Schutzplanken über längere oder kürzere Abstandshalter an den Pfosten festgelegt werden.Furthermore, the invention can be applied to one-sided arranged by posts or provided on both sides of posts guard rail strands and also regardless of whether the guard rails are set to longer or shorter spacers to the post.

Der Abstand der Pfosten untereinander wird den jeweiligen Anforderungen vor Ort angepasst, um eine mögliche Ausbeulung und eine dynamische Durchbiegung zu verringern. Entsprechende Montageöffnungen in den Schutzplanken sind in vorgegebenen Abständen vorhanden.The distance between the posts is adapted to local requirements to reduce possible buckling and dynamic deflection. Corresponding mounting openings in the crash barriers are available at predetermined intervals.

Die Verwindungssteifigkeit der Schutzplanken wird gemäß Anspruch 2 noch dadurch weiter erhöht, dass sich an die Schenkelfortsätze zum Boden hin abgeknickte Endleisten anschließen. Entsprechend der jeweiligen Abwinklung relativ zu den Schenkelfortsätzen ist die Verwindungssteifigkeit variabel bestimmbar.The torsional stiffness of the guard rails is further increased according to claim 2, that connect to the leg extensions to the bottom bent end strips. Corresponding to the respective bending relative to the leg extensions, the torsional rigidity can be determined variably.

Von Vorteil ist es nach der Erfindung, wenn nach Anspruch 3 das Verhältnis der Länge der Schenkelfortsätze zu der Länge der Endleisten etwa 3 : 1 beträgt.It is advantageous according to the invention, when according to claim 3, the ratio of the length of the leg extensions to the length of the end strips is about 3: 1.

Eine vorteilhafte Ausführungsform der Erfindung wird gemäß Anspruch 4 darin gesehen, dass der Winkel zwischen jeder der einander zugewandten Innenseiten der Schenkelfortsätze und der Ebene, in der sich der Boden erstreckt, 95° bis 110° beträgt.An advantageous embodiment of the invention according to claim 4 is seen in that the angle between each of the facing each other Inner sides of the femoral processes and the plane in which the floor extends is 95 ° to 110 °.

In diesem Zusammenhang kann es nach Anspruch 5 ferner vorteilhaft sein, dass die Länge der Versteifungsstege etwa das Drei- bis Vierfache der Dicke der Schutzplanke beträgt.In this context, it may also be advantageous according to claim 5, that the length of the stiffening webs is about three to four times the thickness of the guardrail.

Von Vorteil kann es entsprechend den Merkmalen des Anspruchs 6 darüber hinaus sein, dass der Abstand der Ebene, in der sich der Boden erstreckt, zu der Ebene, welche die Übergangsabschnitte tangiert, größer als der Abstand zu der die Längskanten der Endleisten tangierenden Ebene bemessen ist.It may be advantageous in accordance with the features of claim 6, moreover, that the distance of the plane in which the floor extends, to the plane which is tangent to the transition sections, is greater than the distance to the longitudinal edges of the end strips tangent plane dimensioned ,

Es hat sich gemäß Anspruch 7 bei einer Schutzplanke mit bogenförmigen Übergangsabschnitten ferner als zweckmäßig erwiesen, dass das Verhältnis des Abstands der einerseits die Übergangsabschnitte und andererseits die Längskanten der Endleisten tangierenden Ebenen zu der Distanz zwischen der die Übergangsabschnitte tangierenden Ebene und der Ebene, in der sich der Boden erstreckt, etwa wie 1,6 : 1 bis 1,7 : 1 bemessen ist.It has also proven to be useful according to claim 7 in a guardrail with arcuate transition sections, that the ratio of the distance of one hand, the transition sections and on the other hand, the longitudinal edges of the end strips tangent planes to the distance between the transition portions tangent plane and the plane in which the bottom extends approximately as 1.6: 1 to 1.7: 1 is measured.

Bei dieser Ausführungsform einer Schutzplanke ist es noch von Vorteil, dass nach Anspruch 8 das Verhältnis der Distanz zwischen den beiden Längskanten der Endleisten zu dem Abstand der die bogenförmigen Übergangsabschnitte in ihren Firstbereichen schneidenden beiden Längsebenen etwa wie 1,8:1 bis 1,9:1 bemessen ist.In this embodiment of a protective barrier, it is also advantageous that according to claim 8, the ratio of the distance between the two longitudinal edges of the end strips to the distance of the arcuate transition sections in their ridge regions intersecting two longitudinal planes such as 1.8: 1 to 1.9: 1 is measured.

Ein weiteres zweckmäßiges Merkmal der Erfindung besteht gemäß Anspruch 9 darin, dass der von der Ebene, in der sich der Boden erstreckt, und den Versteifungsstegen eingeschlossene Winkel etwa 15° beträgt.Another expedient feature of the invention according to claim 9 is that the angle enclosed by the plane in which the bottom extends and the stiffening webs is about 15 °.

Bei einer Ausführungsform einer Schutzplanke mit ebenen Übergangsabschnitten zwischen den Innenschenkeln und den Außenschenkeln wird es im Umfang des Anspruchs 10 als zweckmäßig angesehen, dass das Verhältnis des Abstands der einerseits die ebenen Übergangsabschnitte und andererseits die Längskanten der Endleisten tangierenden Ebenen zu dem Abstand zwischen der die Übergangsabschnitte tangierenden Ebene und der Ebene, in der sich der Boden erstreckt, etwa wie 1,2 : 1 bis 1,3 : 1 bemessen ist.In one embodiment of a protective barrier with flat transition sections between the inner legs and the outer legs, it is considered expedient in the scope of claim 10, that the ratio of the distance of the one hand, the flat transition sections and on the other hand, the longitudinal edges of the end strips tangent planes to the distance between the transition sections tangent plane and the The plane in which the soil extends is approximately 1.2: 1 to 1.3: 1.

Ferner ist es bei dieser Ausführungsform von Vorteil, dass nach Anspruch 11 sich die Endleisten in einer Ebene an die Schenkelfortsätze anschließen, in der sich auch der eben ausgebildete Boden erstreckt.Furthermore, it is advantageous in this embodiment that according to claim 11, the end strips in a plane adjoin the leg extensions, in which also extends the newly formed bottom.

Schließlich bildet es entsprechend Anspruch 12 noch ein zweckmäßiges Merkmal der Erfindung, dass das Verhältnis der Distanz zwischen den beiden Längskanten der Endleisten zu dem Abstand der die ebenen Übergangsabschnitte in ihren mittleren Höhenbereichen schneidenden Längsebenen etwa wie 1,8 : 1 bis 1,9 : 1 bemessen ist.Finally, according to claim 12, it still constitutes an expedient feature of the invention that the ratio of the distance between the two longitudinal edges of the end strips to the spacing of the longitudinal planes intersecting the planar transition sections in their middle height ranges is approximately 1.8: 1 to 1.9: 1 is measured.

So können Pfosten 4 jeweils endseitig der Schutzplanke 3 und zusätzlich in der Mitte einer Schutzplanke 3 angeordnet sein.The guard rail assembly 1 is composed of a protective barrier 2 from preferably releasably juxtaposed guard rails 3 and the guard rail 2 supporting, in cross-section sigma-shaped post 4 together, which are rammed into the soil 5. The overlapping at the ends guard rails 3 are connected to each other by means of bolts 6, nuts 7 and 8 discs. The attachment of the guard rails 3 to the post 4 is done with end tabs 9 with the interposition of U-shaped support brackets 10 which are stiffened by a web 11. Here, too, bolt 6, nuts 7 and disks 8 according to FIG. 1 are used. The spacing of the posts 4 from each other is adapted to the particular requirements of the field to reduce possible buckling and dynamic deflection. Thus, posts 4 can each be arranged at the end of the protective barrier 3 and additionally in the middle of a protective barrier 3.

Die Schutzplanken 3 weisen einen im Wesentlichen W-förmigen Querschnitt auf. Wie in diesem Zusammenhang insbesondere Figur 3 erkennen lässt, ist der W-förmige Querschnitt zunächst von einem zentralen Boden 12, von dem Boden 12 aus divergierenden Innenschenkeln 13, von endseitig der Innenschenkel 13 vorgesehenen bogenförmigen Übergangsabschnitten 14 und von sich an die Übergangsabschnitte 14 anschließenden, sich gegensinnig V-förmig zu den Innenschenkeln 13 erstreckenden Außenschenkeln 15 gebildet. Die Übergänge 16 von dem Boden 12 auf die Innenschenkel 13 sind gerundet. Die Außenschenkel 15 enden kurz vor einer Ebene E-E, in der auch der Boden 12 verläuft.The guard rails 3 have a substantially W-shaped cross-section. As can be seen in this context, in particular FIG. 3, the W-shaped cross-section is first of a central bottom 12, of the bottom 12 of diverging inner legs 13, of arcuate transition sections 14 provided at the end of the inner legs 13 and adjoining the transition sections 14 of themselves. formed in opposite directions V-shaped to the inner legs 13 extending outer legs 15. The transitions 16 from the bottom 12 to the inner legs 13 are rounded. The outer legs 15 end shortly before a plane EE, in which the bottom 12 extends.

Aus der Figur 2 ist zu erkennen, dass die Enden der Schenkel 17 der Stützbügel 10 in die von den Übergangsabschnitten 14 gebildeten Kehlen 18 der Schutzplanken 3 fassen.From the figure 2 it can be seen that the ends of the legs 17 of the support bracket 10 in the formed by the transition portions 14 throats 18 of the guard rails 3 summarize.

Wie die Figur 3 weiter zeigt, sind endseitig der Außenschenkel 15 vom Boden 12 weg gerichtete Versteifungsstege 19 vorgesehen, an die sich Schenkelfortsätze 20 anschließen. Der Winkel α zwischen jeder der einander zugewandten Innenseiten 21 der Schenkelfortsätze 20 und der Ebene E-E, in der sich der Boden 12 erstreckt, beträgt beim Ausführungsbeispiel etwa 98°. Die Länge L der Versteifungsstege 19 beträgt etwa das Drei- bis Vierfache der Dicke D der Schutzplanke 3. Außerdem ist zu sehen, dass der von der Ebene E-E, in der sich der Boden 12 erstreckt, und von den Versteifungsstegen 19 eingeschlossene Winkel β etwa 15° beträgt.As FIG. 3 further shows, stiffening webs 19 directed away from the bottom 12 are provided on the end side of the outer leg, to which leg extensions 20 are connected. The angle α between each of the facing inner sides 21 of the leg extensions 20 and the plane E-E, in which the bottom 12 extends, is in the embodiment about 98 °. The length L of the stiffening webs 19 is about three to four times the thickness D of the guard rail 3. In addition, it can be seen that the angle β included by the plane EE in which the bottom 12 extends and the stiffening webs 19 is about 15 ° is.

Die Schenkelfortsätze 20 laufen in zum Boden 12 hin abgeknickte Endleisten 22 aus. Das Verhältnis der Länge L1 der Schenkelfortsätze 20 zu der Länge L2 der Endleisten 22 beträgt etwa 3:1.The femoral processes 20 run in towards the bottom 12 bent end strips 22. The ratio of the length L1 of the leg extensions 20 to the length L2 of the end strips 22 is about 3: 1.

Der Abstand A der Ebene E-E, in der sich der Boden 12 erstreckt, zu der Ebene E1-E1, welche die Übergangsabschnitte 14 tangiert, ist größer als der Abstand A1 zu der die Längskanten 23 der Endleisten 22 tangierenden Ebene E2-E2 bemessen.The distance A of the plane E-E, in which the bottom 12 extends to the plane E1-E1, which affects the transition sections 14, is greater than the distance A1 to the longitudinal edges 23 of the end strips 22 tangent plane E2-E2 dimensioned.

Das Verhältnis des Abstands A2 der einerseits die Übergangsabschnitte 14 und andererseits die Längskanten 23 der Endleisten 22 tangierenden Ebenen E1-E1 bzw. E2-E2 ist zu dem Abstand A zwischen der die Übergangsabschnitte 14 tangierenden Ebene E1-E1 und der Ebene E-E, in der sich der Boden 12 erstreckt, etwa wie 1,6 : 1 bis 1,7 : 1 bemessen.The ratio of the distance A2 on the one hand the transition sections 14 and on the other hand, the longitudinal edges 23 of the end strips 22 tangent planes E1-E1 and E2-E2 is to the distance A between the transition portions 14 tangent plane E1-E1 and the plane EE, in the the bottom 12 extends approximately 1.6: 1 to 1.7: 1.

Das Verhältnis der Distanz D1 zwischen den beiden Längskanten 23 der Endleisten 22 zu dem Abstand A3 der die Übergangsabschnitte 14 in ihren Firstbereichen 24 schneidenden Längsebenen E3-E3 ist etwa wie 1,8 : 1 bis 1,9 : 1 bemessen.The ratio of the distance D1 between the two longitudinal edges 23 of the end strips 22 to the distance A3 of the longitudinal planes E3-E3 intersecting the transition sections 14 in their ridge regions 24 is approximately equal to 1.8: 1 to 1.9: 1.

Der Öffnungswinkel γ zwischen den Innenschenkeln 13 und den Außenschenkeln 15 beträgt etwa 70°. Auch der Öffnungswinkel δ zwischen den Innenschenkeln 13 beträgt etwa 70°.The opening angle γ between the inner legs 13 and the outer legs 15 is about 70 °. The opening angle δ between the inner legs 13 is about 70 °.

Die Figur 4 zeigt, dass eine Schutzplanke 3 ohne weiteres auch stirnseitig eines Abstandshalters 25 befestigt werden kann, der länger als der Stützbügel 10 gemäß Figur 2 ausgebildet ist. Dazu wird der Boden 12 der Schutzplanke 3 mit einem endseitigen Steg 26 des Abstandshalters 25 verschraubt. Die Enden 27 des Abstandshalters 25 fassen dabei in die Kehlen 18 der Schutzplanke 3. Der Abstandshalter 25 wird mittels einer Schlupflasche 28 an einem Pfosten 4 befestigt, der in das Erdreich 5 gerammt ist. Die verwendeten Schraubmittel entsprechen denjenigen der Figur 1.FIG. 4 shows that a guardrail 3 can easily also be fastened to the end face of a spacer 25, which is designed longer than the support bracket 10 according to FIG. For this purpose, the bottom 12 of the protective barrier 3 is screwed to an end-side web 26 of the spacer 25. The ends 27 of the spacer 25 thereby hold in the grooves 18 of the protective barrier 3. The spacer 25 is fastened by means of a slip 28 on a post 4, which is rammed into the soil 5. The screwing means used correspond to those of FIG. 1.

Aus der Figur 8 ist ersichtlich, dass die Schutzplanke 3 so konfiguriert ist, dass sie problemlos mit einer Schutzplanke SP herkömmlicher Bauart gemäß dem Typ A kompatibel ist.It can be seen from FIG. 8 that the guardrail 3 is configured to be easily compatible with a Type A guard rail SP of conventional type.

Die Schutzplanke 3a der Figur 5 besitzt ebenfalls einen im Wesentlichen W-förmigen Querschnitt. Dieser wird von einem zentralen ebenen Boden 12a, von dem Boden 12a aus divergierenden Innenschenkeln 13a, von endseitig der Innenschenkel 13a vorgesehenen fahrbahnseitigen ebenen Übergangsabschnitten 14a, von sich an die Übergangsabschnitte 14a anschließenden, sich gegensinnig zu den Innenschenkeln 13a erstreckenden Außenschenkeln 15a, von endseitig der Außenschenkel 15a vom Boden 12a weg gerichteten Versteifungsstegen 19a und von sich annähernd in Richtung der Außenschenkel 15a erstreckenden Schenkelfortsätzen 20a mit zum Boden 12a hin abgeknickten Endleisten 22a gebildet. Hierbei schließen sich die Endleisten 22a in einer Ebene E4-E4 an die Schenkelfortsätze 20a an, in der sich auch der Boden 12a erstreckt.The guardrail 3a of Figure 5 also has a substantially W-shaped cross-section. This is from a central planar bottom 12a, of the bottom 12a of diverging inner legs 13a, provided by the end of the inner leg 13a roadside planar transition sections 14a, adjoining the transition portions 14a, in opposite directions to the inner legs 13a extending outer legs 15a, from the end of the Outer leg 15a directed away from the bottom 12a stiffening webs 19a and approximately in the direction of the outer legs 15a extending leg extensions 20a formed with the bottom 12a bent end strips 22a. In this case, the end strips 22a in a plane E4-E4 close to the leg extensions 20a, in which the bottom 12a extends.

Der Querschnitt der Schutzplanke 3a ist ferner so aufgebaut, dass das Verhältnis des Abstands A4 der einerseits die ebenen Übergangsabschnitte 14a und andererseits die Längskanten 23a der Endleisten 22a tangierenden Ebenen E5-E5 bzw. E6-E6 zu dem Abstand A5 zwischen der die Übergangsabschnitte 14a tangierenden Ebene E5-E5 und der Ebene E4-E4, in der sich der Boden 12a erstreckt, etwa wie 1,2 : 1 bis 1,3 : 1 bemessen ist.The cross section of the guardrail 3a is further constructed so that the ratio of the distance A4 on the one hand the flat transition portions 14a and on the other hand, the longitudinal edges 23a of the end strips 22a tangent planes E5-E5 and E6-E6 to the distance A5 between the Transition portions 14a tangent plane E5-E5 and the plane E4-E4, in which the bottom 12a extends, is about as 1.2: 1 to 1.3: 1 dimensioned.

Der Öffnungswinkel ε zwischen den Innenschenkeln 13a beträgt etwa 25°, während der Offnungswinkel ζ zwischen einem Innenschenkel 13a und einem Außenschenkel 15a etwa 35° bemessen ist. Der Winkel η zwischen den Versteifungsstegen 19a und der Ebene E5-E5, in der sich die Übergangsabschnitte 14a erstrecken, beträgt etwa 10°.The opening angle ε between the inner legs 13a is about 25 °, while the opening angle ζ between an inner leg 13a and an outer leg 15a is dimensioned about 35 °. The angle η between the stiffening webs 19a and the plane E5-E5, in which the transition portions 14a extend, is about 10 °.

Die Schenkelfortsätze 20a laufen in zum Boden 12a hin abgeknickte Endleisten 22a aus. Das Verhältnis der Länge L1 der Schenkelfortsätze 20a zu der Länge L2 der Endleisten 22a beträgt etwa 3 : 1.The femoral extensions 20a terminate in end strips 22a bent toward the bottom 12a. The ratio of the length L1 of the leg extensions 20a to the length L2 of the end strips 22a is about 3: 1.

Das Verhältnis der Distanz D2 zwischen den beiden Längskanten 23a der Endleisten 22a zu dem Abstand A7 der die Übergangsabschnitte 14a in ihren mittleren Höhenbereichen schneidenden beiden Längsebenen E7 - E7 ist etwa wie 1,8 : 1 bis 1,9 : 1 bemessen.The ratio of the distance D2 between the two longitudinal edges 23a of the end strips 22a to the distance A7 of the two longitudinal planes E7 - E7 intersecting the transition sections 14a in their middle height ranges is approximately equal to 1.8: 1 to 1.9: 1.

Die Schutzplanke 3a kann, wie die Figur 6 zeigt, über einen W-förmigen Stützbügel 29 direkt an einem Pfosten 4 befestigt werden. Hierbei stützt sich der Boden 12a an einem zentralen Vorsprung 30 des Stützbügels 29 ab. Die Schenkel 31 des Stützbügels 29 fassen in die gerundeten Verbindungsabschnitte 32 zwischen den Übergangsabschnitten 14a und den Versteifungsstegen 19a.As shown in FIG. 6, the protective barrier 3a can be fastened directly to a post 4 via a W-shaped support bracket 29. Here, the bottom 12a is supported on a central projection 30 of the support bracket 29. The legs 31 of the support bracket 29 engage in the rounded connecting portions 32 between the transition portions 14a and the stiffening webs 19a.

Es ist aber gemäß Figur 7 auch möglich, eine Schutzplanke 3a an einem Abstandshalter 25 zu befestigen, wie er bereits anhand der Figur 4 beschrieben wurde. Allerdings ist zu sehen, dass sich die Enden 27 des Abstandshalters 25 dann etwa in den mittleren Höhenbereichen der Übergangsabschnitte 14a erstrecken.However, according to FIG. 7, it is also possible to fix a protective barrier 3a to a spacer 25, as has already been described with reference to FIG. However, it can be seen that the ends 27 of the spacer 25 then extend approximately in the middle height regions of the transition sections 14a.

Schließlich ist anhand der Figur 9 zu erkennen, dass auch die Schutzplanke 3a mit einer herkömmlichen Schutzplanke SP 1 des Typs B kompatibel ist.Finally, it can be seen from FIG. 9 that the protective barrier 3a is also compatible with a conventional protection barrier SP 1 of type B.
