Description

Die Erfindung betrifft einen Schutzplankenstrang gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to a guard rail strand according to the features in the preamble of claim 1.

Ein derartiger Schutzplankenstrang ist durch die DE 195 17 933 A1 bekannt. Hierbei wird der Firstholm aus halbierten Baumstammabschnitten von einem gespannten Stahlseil in Längsrichtung durchsetzt. Ein derartiger Schutzplankenstrang kann nicht nur hinsichtlich seines Materials und seiner Formgebung der ländlichen Umgebung einer Fahrbahn optisch ansprechend angepasst, sondern auch den Anforderungen gerecht werden, die an die Schutzfunktion reiner Stahl leitplanken gestellt werden.Such a guardrail strand is through the DE 195 17 933 A1 known. Here the Firstholm is out halved tree trunk sections from a tensioned Steel cable interspersed in the longitudinal direction. Such one Guardrail strand can not only with regard to its Materials and its shape of the rural environment adapted to a road surface in a visually appealing way, but also meet the requirements of the protective function pure steel guardrails.

Bei der bekannten Bauart eines Schutzplankenstrangs hat sich bei internen Anfahrversuchen herausgestellt, dass bei höheren Beanspruchungen das gespannte Drahtseil die Baumstammabschnitte durchschneiden kann. Der Firstholm kann sich dann nicht mehr ordnungsgemäß von den Pfosten lösen. Vielmehr zieht bei einem Aufprall durch ein schwereres Kraftfahrzeug der Firstholm die Pfosten mit weg von der Fahrbahn.Has in the known type of guard rail internal start-up attempts have shown that the tensioned wire rope at higher loads Can cut sections of tree trunk. The Firstholm can then no longer come off the post properly to solve. Rather, in the event of an impact, it pulls through a heavier one Motor vehicle the Firstholm with the posts off the roadway.

Der Erfindung liegt ausgehend vom Stand der Technik die Aufgabe zugrunde, den im Oberbegriff des Anspruchs 1 beschriebenen Schutzplankenstrang derart weiterzubilden, dass er auch höheren Beanspruchungen durch schwere Kraftfahrzeuge vollauf gerecht wird.The invention is based on the prior art Task based on that described in the preamble of claim 1 To further develop the guard rail line that he can also handle higher loads from heavy motor vehicles fully meets.

Die Lösung dieser Aufgabe besteht nach der Erfindung in den im kennzeichnenden Teil des Anspruchs 1 aufgeführten Merkmalen.According to the invention, this object is achieved in those listed in the characterizing part of claim 1 Characteristics.

Danach wird das Zugelement nunmehr als Flachgurt aus einem textilen Material und/oder aus Kunststoff gestaltet und in hochkantiger Erstreckung zwischen die Stammhälften der den Firstholm bildenden Baumstammabschnitte eingegliedert. Insbesondere handelt es sich um ein Textil- und/oder Kunststoffgewebe, z.B. aus Polyestergarnen. Durch entsprechende Variation der Abmessungen des Zugelements in Verbindung mit der Materialwahl kann die Belastungsgrenze feinfühlig reguliert werden. Das Zugelement wird wie ein Sandwich behandelt und bei der Montage des Schutzplankenstrangs zwischen die Stammhälften gelegt. Hierbei kann das Zugelement von einer Rolle gewickelt und in beliebiger Länge zwischen die Stammhälften eingelegt werden. Hiermit ist der Vorteil verbunden, dass der Abstand der Pfosten nicht das bei Stahlschutzplanken genormte Rastermaß von 4.000 mm haben muss.Then the tension element is now made as a flat belt a textile material and / or made of plastic and in an upright extension between the stem halves of the log sections forming the Firstholm. In particular, it is a textile and / or plastic fabric, e.g. made of polyester yarn. By correspondingly varying the dimensions of the tension element in connection with the choice of material, the load limit be carefully regulated. The tension element is treated like a sandwich and when assembling the Guardrail strand placed between the trunk halves. Here, the tension element can be wound from a roll and inserted in any length between the stem halves become. This has the advantage that the distance the post not that of steel guardrails must have a standardized grid dimension of 4,000 mm.

Da der Firstholm über Schlupfhülsen und Sollbruchschrauben mit den Pfosten verbunden ist, wird er sich bei einem Fahrzeuganprall komplett von den Pfosten lösen und verbleibt auch bei von der Fahrbahn abgebogenen Pfosten in seiner ursprünglichen Höhe. Hier bildet dann das Zugelement ein wichtiges Sicherheitsglied zum Auffangen eines Kraftfahrzeugs. Dieses kann nicht über den Schutzplankenstrang hinweg fahren.Because the ridge spar over slip sleeves and predetermined breaking screws connected to the post, he will join one Release the vehicle impact completely from the posts and remain also in the case of posts bent off the road in its original height. The tension element then forms here an important safety element to catch a Motor vehicle. This cannot over the guardrail strand drive away.

Die Pfosten können aus Rohren bestehen oder einen C-förmigen Querschnitt aufweisen. Der Pfostenabstand in Längsrichtung des Schutzplankenstrangs richtet sich nach den jeweiligen Anforderungsstufen.The posts can consist of tubes or a C-shaped one Have cross-section. The post spacing in the longitudinal direction of the guardrail line depends on the respective requirement levels.

Um die Montage des Schutzplankenstrangs zu erleichtern, sehen die Merkmale des Anspruchs 2 vor, dass das Zugelement an mindestens eine Stammhälfte jedes Baumstammabschnitts geheftet ist. Das Heften kann durch Annageln oder mit Hilfe eines Tackers erfolgen.To facilitate the installation of the guardrail line, provide the features of claim 2 that the tension element on at least one half of the trunk of each log section is stapled. Stapling can be done by nailing or with the help of a stapler.

Die den Firstholm bildenden Baumstammabschnitte sind gemäß der Ausführungsform des Anspruchs 3 in nach oben offenen und mit den Schlupfhülsen verbundenen, insbesondere verschweißten, metallischen Schalen befestigt. Diese Schalen haben etwa die Konturbreite der Pfosten und erstrecken sich bevorzugt über etwa den unteren Umfangsbereich der Baumstammabschnitte. Die Befestigung der Baumstammabschnitte in den Schalen kann durch Schraubnägel oder Holzschrauben erfolgen. Die metallischen Schlupfhülsen übergreifen bei C-förmigen Pfosten diese Pfosten. Bei runden Pfosten fassen die Schlupfhülsen bevorzugt in die Pfosten. Schlupfhülsen und Laschen bestehen insbesondere aus Stahl.The tree trunk sections forming the Firstholm are according to the embodiment of claim 3 in open to the top and connected to the slip sleeves, in particular welded, metallic shells attached. This Shells have approximately the contour width of the posts and extend preferably over about the lower peripheral region the tree trunk sections. The fastening of the tree trunk sections in the shells can by screw nails or wood screws. The metallic hatchets overlap these posts in the case of C-shaped posts. At Round posts prefer to hold the slip sleeves in the Post. Slip sleeves and tabs exist in particular from steel.

Gemäß Anspruch 4 werden die Baumstammabschnitte mittels Bandschellen an den Schalen festgelegt. Hiermit kann gezielt dem Charakter von Holz Rechnung getragen werden.According to claim 4, the tree trunk sections are by means of Band clamps set on the shells. Hereby specifically take into account the character of wood.

Eine weitere Ausführungsform der Erfindung besteht in den Merkmalen des Anspruchs 5. Danach werden die Baumstammabschnitte an metallischen Laschen festgelegt, insbesondere mit diesen verschraubt, die ihrerseits mit den metallischen Schlupfhülsen verbunden, insbesondere verschweißt, sind. Diese Laschen erstrecken sich bevorzugt oberhalb der Schlupfhülsen und liegen in der vertikalen Trennebene zwischen den Stammhälften. Bei dieser Ausführungsform sind die tragenden Metallteile bis auf die Pfosten von den Stammhälften ummantelt.Another embodiment of the invention consists in the Features of claim 5. After that, the tree trunk sections attached to metallic tabs, especially screwed with these, which in turn with the metallic Slip sleeves connected, in particular welded, are. These tabs preferably extend above of the slip sleeves and lie in the vertical parting plane between the stem halves. In this embodiment are the supporting metal parts except for the posts of encased the stem halves.

Eine optisch ansprechende und stabile Verbindung der in Längsrichtung aneinander stoßenden Baumstammabschnitte wird mit den Merkmalen des Anspruchs 6 erzielt. Danach sind die Stammhälften der aufeinanderfolgenden Baumstammabschnitte in Längsrichtung zueinander versetzt. Auf diese Art und Weise können zudem stabile Verbindungsbereiche geschaffen werden.A visually appealing and stable connection of the in Longitudinally abutting tree trunk sections is achieved with the features of claim 6. After that are the trunk halves of the successive tree trunk sections offset to each other in the longitudinal direction. On this way, stable connection areas can also be created be created.

Die Belastbarkeit eines Schutzplankenstrangs kann mit den Merkmalen des Anspruchs 7 noch weiter erhöht werden. Dazu ist in dem Höhenbereich zwischen dem Firstholm und dem Boden ein zum Firstholm paralleler Mittenholm vorgesehen. Auch dieser Mittenholm besteht aus Baumstammabschnitten, die jeweils aus miteinander verschraubten Stammhälften zusammengesetzt sind. Hierbei erstrecken sich die Baumstammabschnitte bevorzugt von Pfosten zu Pfosten. Sie sind an metallischen Laschen festgelegt, die in Längsrichtung von metallischen Schlupfhülsen abstehen, die in mittlerer Höhe mittels Sollbruchschrauben an den Pfosten festgelegt sind. Auch der Mittenholm kann bei Bedarf von einem Zugelement in Form eines Flachgurts aus textilem Material und/oder aus Kunststoff in hochkantiger Erstreckung durchzogen sein.The resilience of a guardrail strand can be with the Features of claim 7 can be further increased. To is in the height range between the Firstholm and the Floor provided a central spar parallel to the ridge spar. This central spar also consists of tree trunk sections, each consisting of stem halves screwed together are composed. Here the tree trunk sections extend preferably from post to post. she are attached to metal tabs that run lengthways protrude from metallic slip sleeves, which in medium height using predetermined breaking screws on the posts are set. The central spar can also be used by a tension element in the form of a flat belt made of textile Material and / or plastic in an upright extension be pulled through.

Bei einem Fahrzeuganprall wird sich der Firstholm komplett von den Pfosten lösen und dann wie ein Zugband wirken. Der Mittenholm wird sich etwas nach oben schieben und seine Aufhalteenergie ins Fahrzeug abgeben.In the event of a vehicle collision, the Firstholm becomes complete detach from the posts and then act like a drawstring. The center spar will push up a little and release its hold-up energy into the vehicle.

Mit 1 ist in der Figur 1 ein Schutzplankenstrang bezeichnet, wie er in insbesondere ländlicher, bevorzugt waldiger Umgebung, neben einer Fahrbahn 2 angeordnet ist.1 in FIG. 1 denotes a protective barrier strand, like it is especially rural, preferably wooded Environment, next to a lane 2 is arranged.

Der Schutzplankenstrang 1 weist einen im wesentlichen parallel zu der Fahrbahn 2 verlaufenden Firstholm 3 aus runden Baumstammabschnitten 4 auf (siehe auch Figuren 2 bis 4). Der Firstholm 3 ist an vertikalen Pfosten 5 mit einem C-förmigen Querschnitt befestigt, die in den Boden 6 gerammt sind. Die Oberflächen der Pfosten 5 sind mit einer Beschichtung versehen, die einen Holzcharakter aufweist.The guardrail strand 1 essentially has one First spar 3 running parallel to roadway 2 round tree trunk sections 4 (see also FIGS. 2 to 4). The Firstholm 3 is on vertical posts 5 with a C-shaped cross section attached to the bottom 6 are rammed. The surfaces of the posts 5 are with provided with a coating that has a wood character.

Wie die Figuren 2, 3, 5 und 6 erkennen lassen, besteht jeder Baumstammabschnitt 4 aus zwei Stammhälften 7, 8. Die Trennebene TE der Stammhälften 7, 8 verläuft vertikal.As can be seen in FIGS. 2, 3, 5 and 6, there is each tree trunk section 4 from two trunk halves 7, 8. The parting plane TE of the stem halves 7, 8 runs vertically.

Aus den Figuren 1 und 5 ist ersichtlich, dass im Verbindungsbereich 9 zweier Baumstammabschnitte 4 die Stammhälften 7, 8 in Längsrichtung zueinander versetzt angeordnet sind. Auf diese Weise können, wie auch die Figur 6 erkennen lässt, insgesamt zwölf Schraubbolzen 10 paarweise mit Muttern 11 vorgesehen werden, um die Stammhälften 7, 8 zweier aneinander stoßenden Baumstammabschnitte 4 sicher miteinander zu verbinden. Die Schraubbolzen 10 durchsetzen hierbei Bohrungen 12 in den Stammhälften 7, 8 (Figur 6), wobei ihre Köpfe 13 in Einsenkungen 14 der Stammhälften 8 liegen. Auch die Muttern 11 liegen in Einsenkungen 15 der Stammhälften 7.It can be seen from FIGS. 1 and 5 that in the connection area 9 two tree trunk sections 4 the trunk halves 7, 8 arranged in the longitudinal direction offset from one another are. In this way, like FIG. 6 reveals a total of twelve bolts 10 in pairs be provided with nuts 11 to the trunk halves 7, 8 of two abutting tree trunk sections 4 to connect securely. The bolts 10 penetrate holes 12 in the stem halves 7, 8 (Figure 6), with their heads 13 in depressions 14 of Stem halves 8 lie. The nuts 11 are also in depressions 15 of the stem halves 7.

Bei der Ausführungsform eines Schutzplankenstrangs 1 gemäß den Figuren 1 bis 6 sind die Baumstammabschnitte 4 in nach oben offenen stählernen Schalen 16 gelagert und mit den Schalen 16 durch Holzschrauben 17 verbunden (Figuren 2 und 4). Dazu sind in den Schalen 16 entsprechende Bohrungen 18 vorgesehen. Die Schalen 16 erstrecken sich über die untere Hälfte des Umfangs der Baumstammabschnitte 4.In the embodiment of a guardrail strand 1 according to Figures 1 to 6 are the tree trunk sections 4 in steel shells 16 open to the top and stored with the shells 16 connected by wood screws 17 (figures 2 and 4). For this purpose, 16 corresponding holes are in the shells 18 provided. The shells 16 extend over the lower half of the circumference of the tree trunk sections 4.

In strichpunktierter Linienführung ist in der Figur 2 außerdem noch dargestellt, dass die Baumstammabschnitte 4 auch mittels Bandschellen 28 an den Schalen 16 festgelegt sein können. Die Bandschellen 28 umfassen die Baumstammabschnitte 4 und die seitlichen Bereiche der Schalen 16. Die Holzschrauben 17 dienen auch zu ihrer Befestigung.The dash-dotted lines in FIG. 2 also shown that the log sections 4 also fixed to the shells 16 by means of band clamps 28 could be. The band clamps 28 encompass the tree trunk sections 4 and the side areas of the shells 16. The wood screws 17 also serve to secure them.

Wie die Figuren 1 bis 4 erkennen lassen, sind die Schalen 16 mit im Querschnitt rechteckigen stählernen Schlupfhülsen 19 verschweißt, welche die oberen Enden der Pfosten 5 formschlüssig übergreifen. Die Schlupfhülsen 19 sind mit den Pfosten 5 über zwei übereinander angeordnete Sollbruchschrauben 20 verbunden (Figuren 2 und 4). Dazu sind in den Schlupfhülsen 19 entsprechende Langlöcher 21 vorgesehen.As can be seen from FIGS. 1 to 4, the shells are 16 with steel slip sleeves which are rectangular in cross section 19 welded to the top ends of the posts 5 overlap positively. The slip sleeves 19 are with the post 5 via two predetermined breaking screws arranged one above the other 20 connected (Figures 2 and 4). To do this Corresponding elongated holes 21 are provided in the slip sleeves 19.

Aus den Figuren 2, 3, 5 und 6 ist ersichtlich, dass zwischen die Stammhälften 7, 8 der Baumstammabschnitte 4 ein Zugelement 22 in Form eines hochkant gestellten Flachgurts eingegliedert ist. Das Zugelement 22 besteht insbesondere aus einem Polyestergewebe. Es erstreckt sich durchgehend über die gesamte Länge des Firstholms 3. Es kann bei der Montage des Schutzplankenstrangs 1 an jeweils eine Stammhälfte 7 oder 8 eines Baumstammabschnitts 4 angetackert werden. Hierbei ist es von einer Vorratsrolle abwickelbar. Bei der Verbindung der Stammhälften 7, 8 eines Baumstammabschnitts 4 wird das Zugelement 22 dann mit durchbohrt und, wie aus den Figuren 5 und 6 ersichtlich ist, dadurch fest zwischen die Stammhälften 7, 8 eingegliedert. Die Breite (Höhe) des Zugelements 22 entspricht dem Durchmesser des Firstholms 3.It can be seen from FIGS. 2, 3, 5 and 6 that between the trunk halves 7, 8 of the tree trunk sections 4 Tension element 22 in the form of an upright flat belt is incorporated. The tension element 22 is in particular made of a polyester fabric. It stretches throughout the entire length of the ridge spar 3. Es can in each case when installing the guardrail strand 1 a trunk half 7 or 8 of a log section 4 can be tacked on. Here it is from a supply roll unwindable. When connecting the stem halves 7, 8 of a log section 4, the tension element 22 is then with pierced and, as can be seen from Figures 5 and 6 is fixed between the stem halves 7, 8 incorporated. The width (height) of the tension element 22 corresponds the diameter of the ridge spar 3.

Die Ausführungsform eines Schutzplankenstrangs 1a der Figur 7 sieht einen Firstholm 3a und zwischen dem Firstholm 3a und dem Boden 6 einen weiteren parallelen Mittenholm 23 vor.The embodiment of a guardrail strand 1a of the figure 7 sees a ridge beam 3a and between the ridge beam 3a and the bottom 6 a further parallel central spar 23 before.

Der Firstholm 3a besteht aus vertikal geteilten Baumstammabschnitten 4a. Diese setzen sich wiederum aus jeweils zwei Stammhälften 7a, 8a zusammen, die in den vertikalen Querebenen QE der Pfosten 5a aneinander stoßen. Die oberen Enden der Pfosten 5a werden von Schlupfhülsen 19a übergriffen (siehe auch Figur 8), welche sich in Längsrichtung erstreckende vertikale Laschen 24 mit Langlöchern 25 tragen. Die mittig an die oberen Enden der Schlupfhülsen 19a geschweißten Laschen 24 liegen dann in der Trennebene TE der Stammhälften 7a, 8a neben dem sich durch den Firstholm 3a erstreckenden Zugelement 22. Die Verbindung erfolgt über Schraubbolzen 10 und Muttern 11, wie in der Figur 6 dargestellt.The Firstholm 3a consists of vertically divided tree trunk sections 4a. These in turn consist of each two stem halves 7a, 8a together, in the vertical Abut cross planes QE of posts 5a. The upper ends of the posts 5a are made of slip sleeves 19a (see also FIG. 8), which can be seen in Vertical straps 24 extending in the longitudinal direction Wear elongated holes 25. The middle of the top ends of the Slip sleeves 19a welded tabs 24 are then in the parting plane TE of the stem halves 7a, 8a next to the through the first member 3a extending tension element 22. Die Connection is made using bolts 10 and nuts 11, as shown in Figure 6.

Auch die Schlupfhülse 19a gemäß Figur 8 ist über eine Sollbruchschraube 20a mit einem C-förmigen Pfosten 5a verbunden.The slip sleeve 19a according to FIG. 8 is also via a Breaking screw 20a with a C-shaped post 5a connected.

Der Mittenholm 23 besteht ebenfalls aus Baumstammabschnitten 4b, die sich aus zwei Stammhälften 7b, 8b zusammensetzen. Jeder Baumstammabschnitt 4b erstreckt sich von Pfosten 5a zu Pfosten 5a. Die Verbindung erfolgt über sich in der Trennebene TE des Mittenholms 23 erstreckende Laschen 26 mit Langlöchern 27 (Figur 9), die stirnseitig an im Querschnitt rechteckige Schlupfhülsen 19b angeschweißt sind, welche die Pfosten 5a umgreifen und mittels zweier Sollbruchschrauben 20b an den Pfosten 5a festgelegt sind. Auch der Mittenholm 23 kann zwischen den Pfosten 5a mit einem Zugelement 22 versehen sein. Die Schlupfhülsen 19b sind mit vertikalen Langlöchern 28 versehen. The central spar 23 also consists of tree trunk sections 4b, which are composed of two stem halves 7b, 8b. Each log section 4b extends from post 5a to post 5a. The connection is made via extending in the parting plane TE of the center spar 23 Tabs 26 with elongated holes 27 (Figure 9), the front welded to cross-sectional slip sleeves 19b are, which embrace the posts 5a and by means of two predetermined breaking screws 20b on the posts 5a are set. The center spar 23 can also between the Post 5a be provided with a tension element 22. The Slip sleeves 19b are provided with vertical elongated holes 28.
