Definitions
- the present invention relates to a post assembly for attaching a guard rail construction to structures comprising a foot plate by means of which the post assembly is attachable to the structure, a post attached to the foot plate, the guard rail construction being provided on the post, and a strut attached to the foot plate ,
- the present invention further relates to a guard rail construction for securing roadways on structures.
- Such post arrangements are known from the prior art and for example in the document DE 296 17 846 U1 disclosed.
- This document discloses a post assembly consisting of a post and a supporting post supporting it.
- the post and the support post are mounted on a common base plate by means of a welded joint.
- the post and the support post are welded together.
- the welded connection between the upright post and the foot plate has a predetermined breaking point, which is to ensure that, after breaking the predetermined breaking point, the post post inwardly buckles in the direction of the support post and deflects the vehicle downwards.
- the support post also has a predetermined bending region in the form of a recess.
- the Sollknick Scotland is provided in a mounting area between the support post and the post and should facilitate buckling of the post.
- guard rail construction for securing roadways on or on structures offer only an insufficient compromise between a high stopping power for heavy vehicles and a deformation behavior in which a high proportion of the impact energy of a motor vehicle on the Post assembly is reduced in order to minimize the burden on the occupants in a vehicle. If the stoppage of a guard rail design is too low, a vehicle may break the guard rail construction in the worst case, which could have disastrous consequences for a guard rail construction, for example, mounted on a bridge. Otherwise, in case of a too "hard” guard rail construction the vehicle occupants of an impacting light vehicle are significantly injured.
- a post assembly of the type described in which the strut at least partially surrounds the post, extending in the direction of the post and is spaced at its post next range by a predetermined distance from the post.
- the post assembly according to the invention ensures improved deformation behavior, since in the event of a vehicle colliding with a guard rail construction provided with the inventive post arrangement, first only the post is deformed in the direction of the strut.
- the strut is initially not loaded or deformed in contrast to the prior art due to the predetermined distance between itself and the post.
- An impacting passenger car should therefore be held up by a slight deformation of the post without the use of the strut of a provided with the inventive post assembly guard rail construction and can be directed back to the road.
- a heavier vehicle such as a truck, against a provided with the inventive post arrangement guard rail construction of the post is further deformed in the direction of the strut and is supported on this.
- the strut extends obliquely from the footplate in the direction of the post and sets with its footplate opposite end of the predetermined distance to the post.
- the strut extends from the footplate at a 90 ° angle to the footplate, ie the strut is parallel to the post, and thereby the strut is spaced from the post by the predetermined distance.
- the strut may be in the form of an angle, ie with a section extending parallel to the post and a section parallel to the base plate, the predetermined distance to the post being set with the section extending to the base plate.
- the posts deform not only perpendicular to the road but also in the direction of travel of the impacting vehicle.
- the strut is preferably U-shaped.
- the two side webs of the U-shaped strut close the post at least partially between them.
- the strut is arranged relative to the post on the base plate and formed such that the position of the strut is tuned to the expected impact angle of an impacting vehicle.
- the post is deformed in the crash of a vehicle in the direction of the strut and attaches to this.
- the foot plate opposite end of the strut defines after exceeding the predetermined distance between the post and strut a desired bending point of the post.
- the post is subdivided into two sections, with the section of the post above the setpoint bending point being deformed more strongly during the deformation period than the section below the setpoint bending point. Because of this achieved by the desired bending point deformation behavior, the junction between the post and base plate can be relieved and a controllable deformation behavior can be achieved.
- the footplate is dimensioned and connected to the structure such that the footplate can "buckle" in the event of a vehicle impact.
- the containment level must be taken into account to achieve a provided with the post assembly guard rail construction.
- the footplate according to the invention is formed with a thickness in a range of 10 to 25 mm, in particular in a range of 10 to 15 mm.
- the foot plate is connected to at least two points with the building, or screwed to support this deformation behavior. A compound of the base plate at two points with the building is sufficient here, since in the event of a crash only the road closest to the connection elements are charged and more distant from the roadway connecting elements are quasi “bridged", ie not burdened.
- the present invention further relates to a guard rail construction for securing roadways on structures.
- the protective barrier construction has a plurality of post arrangements of the type described above, wherein post assemblies are connectable via their foot plate to the building, and further comprises at least one extending along the longitudinal axis protective barrier strand.
- the strut of the post assemblies is provided on the side facing away from the guard rail side of the post.
- a deformation element between the posts of the post assemblies and the at least one protective barrier is provided according to the invention.
- the impact of the vehicle on the deformation time of the deformation element is extended in time, whereby the delay and thus the load on the occupants can be significantly reduced.
- a support element is in each case arranged between the deformation element and the protective barrier strand for supporting the protective barrier strand.
- An attachment portion of the support member extends parallel to the post.
- an intermediate element is arranged between the support element and the protective barrier strand.
- the intermediate element has a beveled extending surface, by means of which an angle of inclination of the protective barrier strand is adjustable relative to the longitudinal axis of the post.
- the support element is relative to the longitudinal axis of the Post formed asymmetrically and has at least one leg which protrudes from the attachment portion in the direction of the protective barrier strand.
- the support member according to a preferred embodiment of the invention comprises two legs projecting from the attachment portion, each extending at an angle to the longitudinal axis of the posts, the angles of the projecting legs differing relative to the attachment portion.
- the two angles between the legs of the support member and the attachment portion may be designed such that the leg nearest the soleplate of the support member first deforms, thereby increasing the angle of inclination of the guardrail strand to the longitudinal axis of the posts is maintained.
- a railing stringer strand extending along a longitudinal axis of the guard rail construction is provided on the opposite end of the post of the post assembly.
- the railing stringer strand has at least one angle element.
- the angle element is preferably attached to the post with a predetermined breaking screw.
- the connection of the angle element with the post via a predetermined breaking screw ensures that the railing rail solves at a high impact load on the guard rail construction of the guard rail construction and can act alone as a drawstring.
- the connection between the angle element and the post breaks in an overload, thereby preventing the railing stringer strand is pressed together with the folding post to the ground.
- the railing stringer strand thus remains at a certain height and can further decelerate an impacting vehicle and steer it back onto the roadway. Accordingly, the railing stringer strand, together with the angle element, effectively prevents the guardrail structure from being run over by a vehicle.

- the side bars of the strut 16 partially enclose the posts 12 between them. However, the side webs of the strut 16 are also spaced from the post 12. In other words, the strut 16 touches the post 12 at no point.
- FIG. 4 a plan view of the post assembly 10 is shown. It can be seen the four openings 22 formed in the form of a slot in the base plate 14th
- the strut 16 with its foot plate 14 opposite end 16 b sets a predetermined distance d to the post 12.
- the strut 16 is U-shaped in cross-section and encloses with the side webs of their U-shaped profile the post 12th
- the strut 16 starting from its end 16a connected to the base plate 14, extends obliquely in the direction of the post 12, ie approaches the post 12 by its oblique course. With its foot plate 14 opposite end 16 b, the strut 16 a predetermined distance d to the post 12 a.

- the railing stringer strand 126 can thus intercept impacting vehicles even with heavily deformed posts 12 and direct it back onto the roadway.
- the support member 132 is formed asymmetrically with its two legs 132a and 132b.
- the intermediate element 136 arranged between the support element 132 and the protective barrier strand 130 serves to adapt the angle of inclination of the protective barrier strand 130 to the asymmetrical configuration of the support element 132.
- the protective barrier strand 130 has an inclination relative to the longitudinal axis of the posts 12.
- FIGS. 13 to 16 In the following two embodiments of the support members 132 and the associated intermediate elements 136 will be described. That in the FIGS. 13 and 14 shown embodiment relates to a support member 132, which is designed for a guard rail 130 with B-profile.
- the embodiment according to the FIGS. 15 and 16 refers to a support member 132 for a guardrail 130 with A-profile.
- FIG. 13 shows views of the support member 132 according to a first embodiment. Out FIG. 13 is seen on the asymmetric design of the support member 132.
- the asymmetrical shape of the support member 132 is necessary to adjust the support member 132 at the angle of the guardrail strand 130 defined by the intermediate member 136 relative to the longitudinal axis of the profile posts 12.
- An angle beta of the leg 132a to the profile post 12 or its longitudinal axis is smaller than an angle alpha between the longitudinal axis of the post 12 and the leg 132b, which is closer to the ground.
- the deformation behavior of the support plank construction 100 is positively influenced in the event of a collision of a motor vehicle, which will be described in detail in the following of this description.
- the intermediate member 136 is provided, which is provided on the attachment portion 132 c of the support member 132. It can also be seen clearly that the angle alpha of the leg 132b to the parallel to the longitudinal axis of the profile post 12 extending mounting portion 132c is significantly greater than the angle beta of the leg 132a to the mounting portion 132c. It is thereby achieved that, in the event of a collision of a vehicle, the lower leg 132b closer to the building first deforms. The faster deformation of the lower leg 132b compared to the deformation time of the upper leg 132a ensures that the crash barrier 130 at least maintains its inclination in the event of a collision with a vehicle and does not shift downwards as the deformation progresses.
- the force exerted by an impacting vehicle on the guard rail construction 100 due to the larger angle alpha of the leg 132b, has a larger lever arm from the bend where the attachment portion 132c merges into the leg 132a compared to the smaller one Angle beta of the leg 132a, whereby the leg 132b deformed much faster than the leg 132a.
- FIG. 14 shows various views of the intermediate element 136.
- the intermediate element 136 is wedge-shaped and has for this purpose a vertically extending surface 136b, which can rest against the attachment portion 132c of the support element 132.
- the surface 136a of the intermediate element 136 opposite the surface 136b extends obliquely to the surface 136b in order to adjust the angle of inclination of the protective barrier strand 130 to the longitudinal axis of the profile posts 12.
- the angle of inclination of the protective barrier 130 to the longitudinal axis of the profile posts 12 can also be adjusted by the structural design of the support element 132 with the legs 132a and 132b or over the length of the legs 132a and 132b. In other words, the leg 132b may be shortened with respect to the upper leg 132a.
- FIG. 15 shows views of a support member 132 according to a second embodiment and FIG. 16 shows various views of a matched to the support member 132 according to the second embodiment intermediate member 136th
- the lower leg 132b extends at an angle alpha to the mounting portion 132c, whereas the upper leg 132a is perpendicular (angle ⁇ ) to the mounting portion 132c, ie, the upper leg 132a extends at a 90 ° angle to the mounting portion 132c ,
- the intermediate element 136 according to this exemplary embodiment has to be made thicker (not shown here) due to the protective plank strand formed with the A-profile.
- the intermediate member 136 is adapted to be adapted to the A-profile of the guard rail (not shown) widened compared to the first embodiment described above. Due to the differences between the A and B profiles, the wedge-shaped intermediate element 136 must be widened, ie the distance between the surfaces 136a and 136b is greater than that with respect to FIG FIG. 14 described embodiment, since the A-profile of the protective barrier strand 130 would abut the oblique attachment by the intermediate member 136 with one end to the post 12. Such a system could adversely affect the deformation behavior of the guard rail assembly 100 and the support member 132, respectively.
- FIG. 17 shows a cross-sectional view of the railing stringer strand 128.
- the railing stringer strand 128 is formed mirror-symmetrically to the axis S and has a roof profile in cross section.
- FIG. 18 shows a perspective view of the angle member 128 with which the railing string 126 can be attached to the post 12.
- the angle member 128 has a portion 128 a with two openings 140 which are provided for receiving screws for fixing the angle member 128 to the railing rail 126.
- the section 128b with the opening 142 serves to secure the angle element 128 or the railing stringer strand 126 to the post 12.
- predetermined breaking screws (not shown here) can be received, which break at a certain force acting on them.
- the angle element 128 designed and dimensioned such that it itself has a predetermined breaking point or represents a predetermined breaking element.
- FIGS. 19a to 19e Now the deformation behavior of the guard rail construction 100 is shown.
- FIG. 19a represents the basic position of the guard rail construction 100, ie before the vehicle crash.
- deformation element 134 is first compressed to already dissipate a portion of the impact energy.
- the deformation element 134 is further compressed by an impacting vehicle and the post 12 is deformed in the direction of the strut 16. Further shows FIG. 19c already, that the railing stringer strand 126 slightly tilted relative to the post 12. This is due to the fact that the railing stringer strand 126 already acts in this deformation state due to the slight inclination of the post 12 as a closed drawstring. In other words, an impacting vehicle is not abruptly decelerated because the impact energy of an impacting vehicle is degraded beyond the described deformation of the posts 12 and the deformation members 134.
- FIG. 17c It is also clear that the portion of the post 12 is further deformed above the desired bending point, while the portion below the desired bending point almost maintains its degree of deformation or degree of bending.
- the lever arm of the post 12 is greatly shortened relative to the base plate 14 by the desired bending point of the post 12 defined by the strut 16, whereby the connection point between the post 12 and the base plate 14 is relieved.
- the connection between foot plate 14 and post 12 remains, whereby a controllable deformation behavior is achieved.
- the joint between the posts 12 and foot plate 14 contributes to the sizing of the foot plate 14, which is designed to "buckle" during deformation to further relieve the connection between itself and the post 12.
- the railing stringer string 126 with the angle member 128 further tilts relative to the post 12.
- the guardrail 130 rises in support of the support 132 and the angle of inclination of the guard set by the intermediate member 136 Guard rail 130 to act as a drawstring can.
- Figure 19e now shows that the railing stringer strand 126 dissolves in continuous deformation of the guard rail construction 100 of the post 12, that break the angle element 128 with the post 12 connecting predetermined breaking screws.
- the railing stringer strand 126 remains at a predetermined height and acts as a tension band to decelerate impacting vehicles and to be able to deflect back to the roadway.
- the railing string 126 separating from the post 12 prevents the guard rail construction 100 from being run over by an impacting vehicle.

Description
Pfostenanordnung für eine Schutzplankenkonstruktion und Schutzplankenkonstruktion zur Absicherung von Fahrbahnen auf BauwerkenPost arrangement for a guard rail construction and guard rail construction for securing roadways on structures
Die vorliegende Erfindung betrifft eine Pfostenanordnung zum Befestigen einer Schutzplankenkonstruktion auf Bauwerken, mit einer Fußplatte, mittels derer die Pfostenanordnung an dem Bauwerk befestigbar ist, einem an der Fußplatte angebrachtem Pfosten, wobei an dem Pfosten die Schutzplankenkonstruktion vorgesehen ist, und einer auf der Fußplatte angebrachten Strebe. Die vorliegende Erfindung betrifft ferner eine Schutzplankenkonstruktion zum Absichern von Fahrbahnen auf Bauwerken.The present invention relates to a post assembly for attaching a guard rail construction to structures comprising a foot plate by means of which the post assembly is attachable to the structure, a post attached to the foot plate, the guard rail construction being provided on the post, and a strut attached to the foot plate , The present invention further relates to a guard rail construction for securing roadways on structures.
Derartige Pfostenanordnungen sind aus dem Stand der Technik bekannt und beispielsweise in dem Dokument
Die aus dem Stand der Technik bekannten Pfostenanordnungen bzw. mit derartigen Pfostenanordnungen versehene Schutzplankenkonstruktionen zum Absichern von Fahrbahnen auf oder an Bauwerken bieten nur einen unzureichenden Kompromiss zwischen einem hohen Aufhaltevermögen für schwere Fahrzeuge und einem Deformationsverhalten, bei dem ein hoher Anteil der Anprallenergie eines Kraftfahrzeugs über die Pfostenanordnung abgebaut wird, um die Belastungen für die Insassen in einem Fahrzeugs möglichst gering zu halten. Wird das Aufhaltevermögen einer Schutzplankenkonstruktion zu gering ausgelegt, kann ein Fahrzeug die Schutzplankenkonstruktion schlimmstenfalls durchbrechen, was gerade bei einer beispielsweise auf einer Brücke angebrachten Schutzplankenkonstruktion verheerende Auswirkungen haben könnte. Andernfalls können bei einer zu "harten" Schutzplankenkonstruktion die Fahrzeuginsassen eines anprallendes leichten Fahrzeugs erheblich zu Schaden kommen.The known from the prior art post assemblies or provided with such posts arrangements guard rail construction for securing roadways on or on structures offer only an insufficient compromise between a high stopping power for heavy vehicles and a deformation behavior in which a high proportion of the impact energy of a motor vehicle on the Post assembly is reduced in order to minimize the burden on the occupants in a vehicle. If the stoppage of a guard rail design is too low, a vehicle may break the guard rail construction in the worst case, which could have disastrous consequences for a guard rail construction, for example, mounted on a bridge. Otherwise, in case of a too "hard" guard rail construction the vehicle occupants of an impacting light vehicle are significantly injured.
Es ist somit eine Aufgabe der vorliegenden Erfindung, eine Pfostenanordnung der eingangs bezeichneten Art bereitzustellen, mit der das höchst mögliche Aufhaltevermögen für schwere Fahrzeuge und gleichzeitig möglichst geringe Belastungen für die Insassen in einem anprallenden Fahrzeug erreicht werden.It is therefore an object of the present invention to provide a post assembly of the type described, with which the highest possible stopping power for heavy vehicles and at the same time the lowest possible loads for the occupants are achieved in an impacting vehicle.
Diese Aufgabe wird durch eine Pfostenanordnung der eingangs bezeichneten Art gelöst, bei der die Strebe den Pfosten zumindest teilweise umgibt, sich in Richtung des Pfostens erstreckt und an ihrem dem Pfosten nächsten Bereich um eine vorbestimmte Distanz von dem Pfosten beabstandet ist.This object is achieved by a post assembly of the type described, in which the strut at least partially surrounds the post, extending in the direction of the post and is spaced at its post next range by a predetermined distance from the post.
Die erfindungsgemäße Pfostenanordnung gewährleistet ein verbessertes Deformationsverhalten, da im Anprallfall eines Fahrzeuges auf eine mit der erfindungsgemäßen Pfostenanordnung versehene Schutzplankenkonstruktion zuerst nur der Pfosten in Richtung der Strebe deformiert wird. Die Strebe wird - im Gegensatz zum Stand der Technik aufgrund der vorbestimmten Distanz zwischen sich und dem Pfosten zunächst nicht belastet bzw. deformiert. Ein anprallender Personenkraftwagen sollte dementsprechend durch eine leichte Deformation des Pfostens ohne Einsatz der Strebe von einer mit der erfindungsgemäßen Pfostenanordnung versehenen Schutzplankenkonstruktion aufgehalten und auf die Fahrbahn zurückgelenkt werden können. Prallt jedoch ein schwereres Fahrzeug, wie z.B. ein Lastkraftwagen, gegen eine mit der erfindungsgemäßen Pfostenanordnung versehene Schutzplankenkonstruktion wird der Pfosten weiter in Richtung der Strebe deformiert und stützt sich an dieser ab. Dadurch wird die Verbindungsstelle zwischen der Fußplatte und dem Pfosten entlastet und ein Reißen der Schweißnaht zwischen Fußplatte und Pfosten verhindert. Mit der erfindungsgemäßen Pfostenanordnung kann somit selbst bei sehr hohen Anprallkräften ein kontrollierbares Deformationsverhalten der Pfostenanordnung erreicht werden. Durch das "zweistufige" Deformationsverhalten der Pfostenanordnung wird zudem erreicht, dass bei anprallenden Personenkraftwagen sehr viel Energie über die Deformation der Pfostenanordnung abgebaut wird, jedoch auch schwere Fahrzeuge aufgehalten werden können, d.h. ein hohes Aufhaltevermögen bereitgestellt wird.The post assembly according to the invention ensures improved deformation behavior, since in the event of a vehicle colliding with a guard rail construction provided with the inventive post arrangement, first only the post is deformed in the direction of the strut. The strut is initially not loaded or deformed in contrast to the prior art due to the predetermined distance between itself and the post. An impacting passenger car should therefore be held up by a slight deformation of the post without the use of the strut of a provided with the inventive post assembly guard rail construction and can be directed back to the road. However, a heavier vehicle such as a truck, against a provided with the inventive post arrangement guard rail construction of the post is further deformed in the direction of the strut and is supported on this. This relieves the joint between the footplate and the post and prevents the weld between the footplate and the post from tearing. With the post assembly according to the invention can thus be achieved even at very high impact forces a controllable deformation behavior of the post assembly. Due to the "two-stage" deformation behavior of the post arrangement is also achieved that in colliding passenger cars a lot of energy is dissipated via the deformation of the post assembly, but also heavy vehicles can be stopped, i. a high stoppage is provided.
Gemäß einer Ausführungsform der Erfindung erstreckt sich die Strebe ausgehend von der Fußplatte schräg in Richtung des Pfostens und stellt mit ihrem der Fußplatte entgegengesetztem Ende die vorbestimmte Distanz zu dem Pfosten ein. Mit der derart gestalteten Strebe wird erreicht, dass sich der Pfosten im Anprallfall zuerst an das der Fußplatte entgegengesetzte Ende der Strebe anlegt, um den Hebelarm des Pfostens relativ zur Fußplatte der Pfostenanordnung zu verkürzen und somit die Verbindungsstelle zwischen dem Pfosten und der Fußplatte zu entlasten. Durch die Schrägstellung der Strebe kann sich die Strebe bei größeren Belastungen zusammen mit dem Pfosten deformieren bzw. verbiegen und so gezielt zum Energieabbau eines anprallenden Fahrzeugen beitragen. Es ist ferner denkbar, dass sich die Strebe ausgehend von der Fußplatte in einem 90° Winkel zu der Fußplatte erstreckt, d.h. die Strebe verläuft parallel zum Pfosten, und dabei ist die Strebe um die vorbestimmte Distanz von dem Pfosten beabstandet. Ferner kann die Strebe in Form eines Winkels ausgebildet sein, d.h. mit einem sich parallel zum Pfosten erstreckenden Abschnitt und einem parallel zur Fußplatte verlaufenden Abschnitt, wobei mit dem zur Fußplatte verlaufenden Abschnitt die vorbestimmte Distanz zu dem Pfosten eingestellt wird.According to one embodiment of the invention, the strut extends obliquely from the footplate in the direction of the post and sets with its footplate opposite end of the predetermined distance to the post. With that kind of thing designed strut is achieved that the post first applies in the event of an impact to the foot plate opposite end of the strut to shorten the lever arm of the post relative to the base plate of the post assembly, thus relieving the joint between the post and the base plate. Due to the inclination of the strut, the strut can deform or bend together with the post at higher loads and thus contribute specifically to the energy reduction of an impacting vehicles. It is also conceivable that the strut extends from the footplate at a 90 ° angle to the footplate, ie the strut is parallel to the post, and thereby the strut is spaced from the post by the predetermined distance. Further, the strut may be in the form of an angle, ie with a section extending parallel to the post and a section parallel to the base plate, the predetermined distance to the post being set with the section extending to the base plate.
Da ein Fahrzeuganprall zumeist in einem Winkel von ca. 8° zur Längsachse der Schutzplankenkonstruktion erfolgt, verformen sich die Pfosten nicht nur senkrecht zur Fahrbahn sondern auch in Fahrtrichtung des anprallenden Fahrzeugs. Dementsprechend ist die Strebe vorzugsweise U-förmig ausgebildet. Die beiden Seitenstege der U-förmigen Strebe schließen den Pfosten zumindest teilweise zwischen sich ein. Als Alternative kann hier vorgesehen sein, die Strebe relativ zu dem Pfosten derart auf der Fußplatte angeordnet und derart ausgebildet ist, dass die Position der Strebe auf den erwarteten Anprallwinkel einen anprallenden Fahrzeugs abgestimmt ist.Since a vehicle impact usually takes place at an angle of about 8 ° to the longitudinal axis of the protective barrier construction, the posts deform not only perpendicular to the road but also in the direction of travel of the impacting vehicle. Accordingly, the strut is preferably U-shaped. The two side webs of the U-shaped strut close the post at least partially between them. Alternatively, it can be provided here, the strut is arranged relative to the post on the base plate and formed such that the position of the strut is tuned to the expected impact angle of an impacting vehicle.
Wie bereits erwähnt, wird der Pfosten im Anprallfall eines Fahrzeugs in Richtung der Strebe deformiert und legt sich an diese an. Mit anderen Worten definiert das der Fußplatte entgegengesetzte Ende der Strebe nach Überschreiten der vorbestimmten Distanz zwischen Pfosten und Strebe eine Soll-Abknickstelle des Pfostens. Durch die derart erreichte Soll-Abknickstelle wird der Pfosten in zwei Abschnitte unterteilt, wobei der Abschnitt des Pfostens oberhalb der Soll-Abknickstelle während des Deformationszeitraums stärker deformiert wird, als der Abschnitt unterhalb der Soll-Abknickstelle. Aufgrund dieses durch die Soll-Abknickstelle erzielte Deformationsverhalten kann die Verbindungsstelle zwischen Pfosten und Fußplatte entlastet und ein kontrollierbares Deformationsverhalten erreicht werden.As already mentioned, the post is deformed in the crash of a vehicle in the direction of the strut and attaches to this. In other words, the foot plate opposite end of the strut defines after exceeding the predetermined distance between the post and strut a desired bending point of the post. As a result of the setpoint bending point achieved in this way, the post is subdivided into two sections, with the section of the post above the setpoint bending point being deformed more strongly during the deformation period than the section below the setpoint bending point. Because of this achieved by the desired bending point deformation behavior, the junction between the post and base plate can be relieved and a controllable deformation behavior can be achieved.
Um ein Reißen der Schweißnaht zwischen Fußplatte und Pfosten weiter zu verhindern, wird die Fußplatte derart dimensioniert und mit dem Bauwerk verbunden, dass sich die Fußplatte im Anprallfall eines Fahrzeugs "aufbeulen" kann. Zudem muss bei der Dimensionierung der Bodenplatte die Aufhaltestufe berücksichtigt werden, die eine mit der Pfostenanordnung versehene Schutzplankenkonstruktion erreichen soll. Unter Berücksichtigung der beiden vorgenannten Bedingungen wird die Fußplatte erfindungsgemäß mit einer Dicke in einem Bereich von 10 bis 25mm, insbesondere in einem Bereich von 10 bis 15mm ausgebildet. Ferner wird die Fußplatte an wenigstens zwei Punkten mit dem Bauwerk verbunden, bzw. verschraubt, um dieses Deformationsverhalten zu unterstützen. Eine Verbindung der Fußplatte an zwei Punkten mit dem Bauwerk ist hier ausreichend, da im Anprallfall eines Fahrzeug nur die der Fahrbahn am nächsten liegenden Verbindungselemente belastet werden und weiter von der Fahrbahn entfernte Verbindungselemente quasi "überbrückt" werden, d.h. nicht belastet werden.To further prevent tearing of the weld between the footplate and the post, the footplate is dimensioned and connected to the structure such that the footplate can "buckle" in the event of a vehicle impact. In addition, when dimensioning the bottom plate, the containment level must be taken into account to achieve a provided with the post assembly guard rail construction. Taking into account the two aforementioned conditions, the footplate according to the invention is formed with a thickness in a range of 10 to 25 mm, in particular in a range of 10 to 15 mm. Further, the foot plate is connected to at least two points with the building, or screwed to support this deformation behavior. A compound of the base plate at two points with the building is sufficient here, since in the event of a crash only the road closest to the connection elements are charged and more distant from the roadway connecting elements are quasi "bridged", ie not burdened.
Die vorliegende Erfindung betrifft ferner eine Schutzplankenkonstruktion zum Absichern von Fahrbahnen auf Bauwerken. Die Schutzplankenkonstruktion weist eine Mehrzahl von Pfostenanordnungen der voranstehend beschriebenen Art, wobei Pfostenanordnungen über ihre Fußplatte mit dem Bauwerk verbindbar sind, und weist ferner wenigstens einen entlang der Längsachse verlaufenden Schutzplankenstrang auf. Die Strebe der Pfostenanordnungen ist dabei an der dem Schutzplankenstrang abgewandten Seite der Pfosten vorgesehen.The present invention further relates to a guard rail construction for securing roadways on structures. The protective barrier construction has a plurality of post arrangements of the type described above, wherein post assemblies are connectable via their foot plate to the building, and further comprises at least one extending along the longitudinal axis protective barrier strand. The strut of the post assemblies is provided on the side facing away from the guard rail side of the post.
Um bereits vor der Deformation der Pfosten einen erheblichen Teil der Anprallenergie eines anprallenden Fahrzeugs abzubauen, ist erfindungsgemäß ein Deformationselement zwischen den Pfosten der Pfostenanordnungen und dem wenigstens einem Schutzplankenstrang vorgesehen. Mit anderen Worten wird das Anschlagen des Fahrzeugs über die Deformationszeit des Deformationselements zeitlich gestreckt, wodurch die Verzögerung und somit die Belastung für die Insassen erheblich verringert werden kann.In order to reduce even before the deformation of the post a considerable part of the impact energy of an impacting vehicle, a deformation element between the posts of the post assemblies and the at least one protective barrier is provided according to the invention. In other words, the impact of the vehicle on the deformation time of the deformation element is extended in time, whereby the delay and thus the load on the occupants can be significantly reduced.
Gemäß einer Ausführungsform ist zur Abstützung des Schutzplankenstrangs ein Stützelement jeweils zwischen dem Deformationselement und dem Schutzplankenstrang angeordnet. Ein Befestigungsabschnitt des Stützelements erstreckt sich parallel zu dem Pfosten. Zudem ist zwischen dem Stützelement und dem Schutzplankenstrang ein Zwischenelement angeordnet.According to one embodiment, a support element is in each case arranged between the deformation element and the protective barrier strand for supporting the protective barrier strand. An attachment portion of the support member extends parallel to the post. In addition, an intermediate element is arranged between the support element and the protective barrier strand.
Bevorzugt ist dabei vorgesehen, dass das Zwischenelement eine abgeschrägt verlaufende Fläche aufweist, mittels derer ein Neigungswinkel des Schutzplankenstrangs relativ zur Längsachse der Pfosten einstellbar ist. Zur Anpassung an den Neigungswinkel des Schutzplankenstrangs ist das Stützelement relativ zur Längsachse des Pfostens asymmetrisch ausgebildet und weist wenigstens einen Schenkel auf, der von dem Befestigungsabschnitt in Richtung des Schutzplankenstrangs vorspringt.Preferably, it is provided that the intermediate element has a beveled extending surface, by means of which an angle of inclination of the protective barrier strand is adjustable relative to the longitudinal axis of the post. To adapt to the angle of inclination of the protective barrier strand, the support element is relative to the longitudinal axis of the Post formed asymmetrically and has at least one leg which protrudes from the attachment portion in the direction of the protective barrier strand.
Das Stützelement weist gemäß einer bevorzugten Ausführungsform der Erfindung zwei von dem Befestigungsabschnitt vorspringende Schenkel auf, die sich jeweils in einem Winkel zur Längsachse der Pfosten erstrecken, wobei sich die Winkel der vorspringenden Schenkel relativ zu dem Befestigungsabschnitt unterscheiden. Mit anderen Worten können zur Vermeidung einer Absenkung des Schutzplankenstrangs bei einem Fahrzeuganprall die beiden Winkel zwischen den Schenkeln des Stützelements und dem Befestigungsabschnitt derart ausgelegt werden, dass sich der der Fußplatte nähere Schenkel des Stützelements zuerst deformiert, wodurch der Neigungswinkel des Schutzplankenstrangs zur Längsachse der Pfosten zumindest beibehalten wird.The support member according to a preferred embodiment of the invention comprises two legs projecting from the attachment portion, each extending at an angle to the longitudinal axis of the posts, the angles of the projecting legs differing relative to the attachment portion. In other words, to avoid sagging of the guardrail string in a vehicle crash, the two angles between the legs of the support member and the attachment portion may be designed such that the leg nearest the soleplate of the support member first deforms, thereby increasing the angle of inclination of the guardrail strand to the longitudinal axis of the posts is maintained.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist an dem der Fußplatte der Pfostenanordnung entgegengesetztem Ende der Pfosten ein Geländerholmstrang vorgesehen, der sich entlang einer Längsachse der Schutzplankenkonstruktion erstreckt.According to a preferred embodiment of the invention, a railing stringer strand extending along a longitudinal axis of the guard rail construction is provided on the opposite end of the post of the post assembly.
Zur Befestigung des Geländerholmstrangs an dem Pfosten weist der Geländerholmstrang wenigstens ein Winkelelement auf. Das Winkelelement ist dabei vorzugsweise mit einer Sollbruchschraube an dem Pfosten angebracht. Die Verbindung des Winkelelements mit dem Pfosten über eine Sollbruchschraube gewährleistet, dass sich der Geländerholm bei einer hohen Anpralllast auf die Schutzplankenkonstruktion von der Schutzplankenkonstruktion löst und alleine als Zugband wirken kann. Mit anderen Worten bricht die Verbindung zwischen dem Winkelelement und dem Pfosten bei einer Überbelastung, wodurch verhindert wird, dass der Geländerholmstrang zusammen mit den umknickenden Pfosten zu Boden gedrückt wird. Der Geländerholmstrang verbleibt also in einer bestimmten Höhe und kann ein anprallendes Fahrzeug weiter abbremsen und zurück auf die Fahrbahn lenken. Der Geländerholmstrang dient dementsprechend zusammen mit dem Winkelelement dazu, dass ein Überfahren der Schutzplankenkonstruktion durch ein Fahrzeug effektiv verhindert wird.For securing the railing stringer strand to the post, the railing stringer strand has at least one angle element. The angle element is preferably attached to the post with a predetermined breaking screw. The connection of the angle element with the post via a predetermined breaking screw ensures that the railing rail solves at a high impact load on the guard rail construction of the guard rail construction and can act alone as a drawstring. In other words, the connection between the angle element and the post breaks in an overload, thereby preventing the railing stringer strand is pressed together with the folding post to the ground. The railing stringer strand thus remains at a certain height and can further decelerate an impacting vehicle and steer it back onto the roadway. Accordingly, the railing stringer strand, together with the angle element, effectively prevents the guardrail structure from being run over by a vehicle.
