Description

Die Erfindung betrifft eine Leiteinrichtung, die auf Kunstbauwerken, wie Brücken, u.ähnl. zu montieren ist, mit den Merkmalen des einleitenden Teils von Anspruch 1 ( NL 7 008 705 A ).The invention relates to a guide on art structures, such as bridges, u.ähnl. with the features of the introductory part of claim 1 ( NL 7 008 705 A ).

Leiteinrichtungen bestehen üblicherweise aus Stehern und wenigstens einem Leitschienenband ("Leitplanke"), das, gegebenenfalls über Zwischenstücke, an den Stehern befestigt ist. Wenn solche Leiteinrichtungen im Gelände zu errichten sind, werden die Steher einfach in den Boden gerammt und dann das Leitschienenband, gegebenenfalls über zwischen Steher und Leitschienenband angeordnete, insbesondere dämpfende Zwischenstücke, an den Stehern befestigt.Guiding devices usually consist of uprights and at least one guardrail strap ("guardrail"), which is fastened, optionally via spacers, to the uprights. If such Leiteinrichtungen are to be erected in the field, the uprights are simply rammed into the ground and then the guard rail, possibly mounted on between stayer and guard rail band, in particular damping intermediate pieces, attached to the uprights.

Auf Bauwerken ist es üblich, die Steher über Grundplatten auf dem Bauwerk, insbesondere auf Randbalken von Brücken (= "Kappen") zu befestigen. Die Befestigung erfolgt mit Hilfe von Ankern. Es hat sich gezeigt, dass bei den üblicherweise verwendeten Befestigungsarten für Steher auf Bauwerken im Falle eines Aufpralls eines Fahrzeuges gegen die Leiteinrichtung die Verankerungen, welche die Grundplatte mit dem Bauwerk verbinden, verformt werden, so dass diese beim Austausch der Steher beim Wiederherstellen der Leiteinrichtung oft nicht mehr verwendbar sind.In buildings, it is customary to attach the posts on base plates on the building, in particular on edge beams of bridges (= "caps"). The attachment takes place with the help of anchors. It has been found that in the commonly used mounting types for uprights on structures in the event of a collision of a vehicle against the guide, the anchors that connect the base plate to the structure, are deformed so that they often when replacing the stayer in restoring the guide are no longer usable.

Aus der NL 7 008 705 A ist eine Leiteinrichtung der eingangs genannten Gattung bekannt. Bei dieser bekannten Leiteinrichtung sind in der mit dem Steher dreiseitig verschweißten Grundplatte in allen vier Ecken der Grundplatte Löcher für die Aufnahme von Befestigungsmitteln vorgesehen, welche die Steher der Leiteinrichtung an einem Untergrund befestigen. Die Schweißnaht, welche bei der aus der NL 7 008 705 A bekannten Leiteinrichtung den Steher mit der Grundplatte verbindet ist, auf drei Seiten der Umfangsfläche des Stehers vorgesehen, wobei die Schweißnaht auf der dem Leitschienenband, das am Steher befestigt ist, gegenüberliegenden Seite des Stehers nicht vorgesehen ist.From the NL 7 008 705 A a guide device of the type mentioned is known. In this known guide holes in the four sides of the base plate holes are provided for receiving fasteners in the three sides welded to the base plate with the base, which secure the uprights of the guide to a substrate. The weld, which at the out of the NL 7 008 705 A known guide means the post with the base plate is connected, provided on three sides of the peripheral surface of the post, wherein the weld on the guide rail, which is attached to the uprights, opposite side of the post is not provided.

Der Erfindung liegt die Aufgabe zu Grunde, eine Leiteinrichtung der eingangs genannten Gattung vorzuschlagen, bei welcher auch im Falle eines Aufpralles eines Fahrzeuges gegen die Leiteinrichtung die Verformarbeit im Bereich der Steher günstiger gestaltet ist.The invention is based on the object to propose a guide of the type mentioned, in which in case of impact of a vehicle against the guide the Deformation work in the area of the stayer is designed more favorable.

Gelöst wird diese Aufgabe erfindungsgemäß mit einem Steher für Leiteinrichtungen, welcher die Merkmale von Anspruch 1 aufweist.This object is achieved according to the invention with a post for guide devices, which has the features of claim 1.

Bevorzugte und vorteilhafte Ausgestaltungen des erfindungsgemäßen Stehers für Leiteinrichtungen sind Gegenstand der Unteransprüche.Preferred and advantageous embodiments of the invention Steuler for guidance devices are the subject of the dependent claims.

Da bei einer bevorzugten Ausführungsform des Steher die Grundplatte über Anker, die mit Abstand seitlich neben dem Steher angeordnet sind, mit dem Bauwerk verbunden ist, die Grundplatte aber im Bereich vor dem Steher (auf dessen der Verkehrsfläche zugekehrten Seite) mit dem Bauwerk nicht verbunden ist, kann sich die Grundplatte bei einem Aufprall in der Weise verformen, dass sie sich zwischen den Befestigungspunkten nach oben wölbt.Since, in a preferred embodiment of the uprights, the base plate is connected to the structure via anchors, which are arranged at a distance laterally next to the upright, but the base plate is not connected to the structure in the area in front of the upright (on the side facing the traffic area) In the event of a collision, the base plate may deform in such a way that it bulges upward between the attachment points.

Dabei ist vorgesehen, die Anker in dem Bereich neben dem der Verkehrsfläche benachbarten Rand der Grundplatte anzuordnen. Dies hat in weiterer Folge den Vorteil, dass die auf den Steher einwirkenden Kräfte in seinen Randbereichen konzentriert sind, so dass der Steher bei zunehmender Belastung in diesen Randbereichen (z.B. den Seitenkanten) oberhalb der Schweißstelle, die den Steher mit der Grundplatte verbindet, einreißt.It is provided to arrange the armature in the area adjacent to the traffic area adjacent edge of the base plate. This has the further advantage that the forces acting on the post are concentrated in its peripheral areas, so that the post tears under increasing load in these marginal areas (e.g., the side edges) above the weld joining the post to the base.

Gemäß der Erfindung ist auf der Oberseite der Grundplatte aufliegend zwischen den Befestigungspunkten (z.B. den Ankern) eine Grundplattenverstärkung in Form eines Metallstreifens, insbesondere Stahlstreifens, mit Durchgangslöchern für die Befestigungsmittel vorgesehen. Durch diese Grundplatten-verstärkung wird verhindert, dass sich die Anker, über welche der Steher über seine Grundplatte mit dem Bauwerk verbunden wird, beim Aufwölben der Grundplatte nach außen biegen, so dass das Auswechseln des Stehers beim Wiederherstellen einer Leiteinrichtung, in die ein Fahrzeug gefahren ist, ohne Behinderung durch verbogene Anker möglich ist.According to the invention, there is provided on the upper side of the base plate, lying between the attachment points (for example the anchors), a base plate reinforcement in the form of a metal strip, in particular steel strip, with through holes for the fastening means. This baseplate reinforcement prevents the anchors, via which the uprights are connected to the structure via its base plate, from bending outward during the arching of the baseplate, so that the replacement of the stanchion when restoring a guide into which a vehicle is driven is possible without obstruction by bent anchors.

Weitere Einzelheiten und Merkmale der Erfindung ergeben sich aus der nachstehenden Beschreibung einer bevorzugten Ausführungsform unter Bezugnahme auf die Zeichnungen.Further details and features of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings.

Es zeigt: Fig. 1 schematisch eine Leiteinrichtung, die auf dem Randbalken ("Kappe") einer Brücke montiert ist, Fig. 2 einen Steher der Leiteinrichtung aus Fig. 1, Fig. 3 den Steher aus Fig. 2 in auseinander gezogener Darstellung und Fig. 4 den Steher im Fall des Einwirkens von Kräften beim Aufprall eines Fahrzeuges.It shows: Fig. 1 schematically a guide on the Edge beam ("cap") of a bridge is mounted, Fig. 2 a post of the guide Fig. 1 . Fig. 3 the stayer Fig. 2 in an exploded view and Fig. 4 the upright in the case of forces acting on the impact of a vehicle.

Die in Fig. 1 gezeigte Leiteinrichtung 2 ist auf einem Bauwerk 4, im gezeigten Ausführungsbeispiel einer Brücke, auf deren Randbalken 6 (auch "Kappe" genannt) angeordnet. Hiezu sind die Steher 10 der Leiteinrichtung 1, die beispielsweise die aus der AT 004 690 U1 bekannte Form ("V-Steher") besitzen können, über Grundplatten 12 unter Verwendung von Ankern 14 befestigt. Beispiele für Anker 14 sind Verbundklebeanker und Ankerschrauben. Die Steher 10 sind an ihrem unteren Ende mit den Grundplatten 12 durch Schweißen verbunden.In the Fig. 1 shown guide 2 is on a building 4, in the illustrated embodiment, a bridge on the edge bar 6 (also called "cap") arranged. For this purpose, the uprights 10 of the guide 1, for example, from the AT 004 690 U1 known form ("V-pillars") may have mounted over base plates 12 using anchors 14. Examples of anchors 14 are composite adhesive anchors and anchor bolts. The uprights 10 are connected at their lower end to the base plates 12 by welding.

Die Leiteinrichtung 2 besitzt im gezeigten Ausführungsbeispiel ein Leitschienenband 15 ("Leitplanke") aus Stahlblechprofilen, die in Längsrichtung gewellt sind, wobei das Leitschienenband 15 über Zwischenstücke 16 mit den Stehern 10 verbunden ist. Unterhalb des Leitschienenbandes 14 ist im gezeigten Ausführungsbeispiel an den Stehern 10 ein Gleitprofil 18 befestigt.The guide 2 has in the illustrated embodiment, a guide rail 15 ("guardrail") made of sheet steel profiles which are corrugated in the longitudinal direction, wherein the guide rail band 15 is connected via spacers 16 with the uprights 10. Below the guardrail 14, a sliding profile 18 is attached to the uprights 10 in the illustrated embodiment.

Wie in Fig. 2 gezeigt, sind die Steher 10 über jeweils eine Grundplatte 12 mit dem Bauwerk 4 durch zwei Anker 14 verbunden. Die Anker 14 sind seitlich - mit Abstand - neben dem Steher 10 angeordnet und in der Grundplatte 12 in deren zur Verkehrsfläche, z.B. der Fahrbahn, hin weisenden Seite, also in der Nähe des der Fahrbahn benachbarten Randes 13 der Grundplatte 12 angeordnet.As in Fig. 2 shown, the uprights 10 are connected via a respective base plate 12 with the structure 4 by two anchors 14. The armatures 14 are arranged laterally-at a distance-next to the upright 10 and are arranged in the base plate 12 in their side facing the traffic area, eg the roadway, ie in the vicinity of the edge 13 of the base plate 12 adjacent to the roadway.

Wie Fig. 3 zeigt, sind in der Grundplatte 12 für die Aufnahme der Anker 14 zwei Langlöcher 20 vorgesehen. Die Längserstreckung der Langlöcher 20 ist parallel zur Fahrbahn und parallel zur längeren Seite 13 der beispielsweise rechteckigen Grundplatte 12 ausgerichtet.As Fig. 3 shows, two elongated holes 20 are provided in the base plate 12 for receiving the armature 14. The longitudinal extent of the elongated holes 20 is aligned parallel to the roadway and parallel to the longer side 13 of the example rectangular base plate 12.

Auf der Grundplatte 12 aufliegend ist ein Metallstreifen 30, z.B. ein Stahlband, als Grundplattenverstärkung vorgesehen. In dem Stahlband 30 sind zwei Löcher 32 für die Aufnahme der Anker 14 vorgesehen.On the base plate 12 is a metal strip 30, e.g. a steel band, intended as a base plate reinforcement. In the steel strip 30, two holes 32 are provided for receiving the armature 14.

Die Anker 14 sind im gezeigten Ausführungsbeispiel im Randbalken 6 einer Brücke versetzt. Zwischen der auf das obere Ende der Anker 14 geschraubten Mutter 34 und dem als Grundplattenverstärkung dienenden Metallstreifen 30 sind Beilagscheiben 36 vorgesehen.The armature 14 are offset in the embodiment shown in the edge bar 6 a bridge. Shims 36 are provided between the nut 34 screwed onto the upper end of the armature 14 and the metal strip 30 serving as the base plate reinforcement.

Die Löcher 32 in dem als Grundplattenverstärkung dienenden Metallstreifen 30 haben gegenüber den Ankern 14 geringes Spiel.The holes 32 in the metal strip 30 serving as the base plate reinforcement have little play with the anchors 14.

Bei Aufprall eines Fahrzeuges gegen die Leiteinrichtung 2 wird sich zunächst das Leitschienenband 15 unter Verformen der Zwischenstücke 16 an die Steher 10 annähern. Dann wird der Steher 10 von der Fahrbahn wegkippen (in Fig. 1 nach rechts), wobei sich, wie in Fig. 4 gezeigt, die Grundplatte 12 zwischen den Ankern 14 nach oben wölbt. Es ist erkennbar, dass sich die auf den Steher 10 einwirkenden Zugkräfte im Bereich seiner der Fahrbahn zugekehrten Kanten 11 konzentrieren, so dass der Steher 10 schlussendlich zuerst im Bereich der Kanten 11 knapp über der Verschweißung zwischen Grundplatte 12 und Steher 10, im Bereich 17, einreisst.Upon collision of a vehicle against the guide 2, the guide rail band 15 will initially approach the spacers 16 by deforming the intermediate pieces 16. Then the post 10 will tip away from the road (in Fig. 1 to the right), where, as in Fig. 4 shown, the base plate 12 bulges between the anchors 14 upwards. It can be seen that the forces acting on the uprights 10 tensile forces in the region of its edges facing the road 11 concentrate, so that the post 10 finally first in the area of the edges 11 just above the welding between base plate 12 and post 10, in the area 17, penetrates.

Die als Metallstreifen 30 ausgebildete Grundplattenverstärkung wird beim Aufwölben der Grundplatte 12 zunächst unter Beilagscheiben 36 relativ zu den Ankern 14 rutschen, bis die äußeren Bereiche der Innenflächen der Löcher 32 in dem Metallstreifen 30 der Grundplattenverstärkung an den Ankern 14 anliegen. Dadurch wirkt der Metallstreifen 30 der Grundplattenverstärkung als Zugband, das verhindert, dass sich die Anker 14 beim Aufwölben der Grundplatte 12 (Fig. 4) mit ihren über das Bauwerk 4 überstehenden Bereichen gegenüber ihren in das Bauwerk 4 eingreifenden Bereichen nach außen verbiegen. Dessen ungeachtet kann sich die Grundplatte 12, wie in Fig. 4 gezeigt, aufwölben, da die von den Ankern 14 durchsetzten Löcher 20 in der Grundplatte 12 als Langlöcher ausgebildet sind.The formed as a metal strip 30 base plate reinforcement will initially slide under washers 36 relative to the anchors 14 when bulging the base plate 12 until the outer portions of the inner surfaces of the holes 32 in the metal strip 30 of the base plate reinforcement abut the anchors 14. As a result, the metal strip 30 of the baseplate reinforcement acts as a drawstring, which prevents the anchors 14 from becoming bulging of the baseplate 12 (FIG. Fig. 4 ) bend with their over the structure 4 projecting areas with respect to their engaging in the structure 4 areas to the outside. Regardless, the base plate 12, as in Fig. 4 shown bulge, since the penetrated by the anchors 14 holes 20 are formed in the base plate 12 as slots.

Der Metallstreifen 30, der bevorzugt ein Stahlband ist und der als Grundplattenverstärkung dient, bewirkt folgende:

  • Solange das Lochspiel in dem Metallstreifen 30 in der Grundplattenverstärkung nicht verbraucht ist, wird das Aufwölben der Grundplatte 12 nicht behindert. Ein Schwenken des Stehers 10 bei einem Aufprall von der Fahrbahn weg wird dadurch ermöglicht.
  • Ab einer bestimmten Aufwölbung der Grundplatte 12 ist das Lochspiel in dem Metallstreifen 30 der Grundplattenverstärkung verbraucht und dieses beginnt als Zugband zu wirken. Diese Zugbandwirkung begrenzt einerseits das Aufwölben der Grundplatte 12 und hält anderseits in Verbindung mit den Langlöchern 20 der Grundplatte 12 die Anker 14 trotz des Aufwölbens gerade.
The metal strip 30, which is preferably a steel strip and serves as a base plate reinforcement, causes the following:
  • As long as the hole play in the metal strip 30 in the base plate reinforcement is not consumed, the bulging of the base plate 12 is not hindered. A pivoting of the post 10 in an impact away from the roadway is thereby made possible.
  • From a certain bulge of the base plate 12, the hole play is consumed in the metal strip 30 of the base plate reinforcement and this begins to act as a drawstring. This Zugbandwirkung limits on the one hand the bulging of the base plate 12 and holds on the other hand in connection with the slots 20 of the base plate 12, the anchor 14 despite the bulging straight.

Durch die erfindungsgemäße Ausbildung des Stehers 10 mit seiner Grundplatte 12 in Verbindung mit dem bevorzugt vorgesehenen Metallstreifen 30, insbesondere Stahlband, als Grundplattenverstärkung wird das Austauschen von Stehern 10, das beim Reparieren von Unfallschäden an der Leiteinrichtung 2 häufig erforderlich ist, nicht behindert, da bei der Erfindung die Verankerung nicht beschädigt wird, also die Anker 14 nicht verformt werden.Due to the inventive design of the post 10 with its base plate 12 in conjunction with the preferably provided metal strip 30, in particular steel strip, as base plate reinforcement replacement of uprights 10, which is often required when repairing accident damage to the guide 2, not hindered since the invention, the anchorage is not damaged, so the anchor 14 are not deformed.

Durch die erfindungsgemäße Ausbildung, insbesondere in der Ausführungsform mit dem Metallstreifen 30, insbesondere dem Stahlband als Grundplattenverstärkung, braucht die Grundplatte 12, statt wie bisher eine Stärke von beispielsweise 15 mm, nur noch eine Stärke von beispielsweise etwa 10 mm haben.Due to the construction according to the invention, in particular in the embodiment with the metal strip 30, in particular the steel strip as the base plate reinforcement, the base plate 12, instead of a thickness of, for example, 15 mm, only needs to have a thickness of, for example, about 10 mm.

Zusammenfassend kann ein Ausführungsbeispiel der Erfindung wie folgt beschrieben werden:In summary, an embodiment of the invention can be described as follows:

Ein Steher 10 einer Leiteinrichtung 2, der auf einem Bauwerk 4 zu befestigen ist, besitzt eine Grundplatte 12, mit welcher der Steher 10 mit seinem unteren Ende verschweißt ist. In der Grundplatte 12 sind seitlich neben dem Fußpunkt des Stehers 10 zwei Langlöcher 20 vorgesehen, deren Längserstreckung parallel zur Fahrbahnrichtung ausgerichtet ist. Auf der Grundplatte 12 liegt im Bereich der Langlöcher 20 ein Metallstreifen 30 als Grundplattenverstärkung auf, das Löcher 32 für den Durchgriff von Ankern 14 aufweist, die ebenfalls die Langlöcher 20 in der Grundplatte 12 durchgreifen, und im Bauwerk 4 festgelegt sind. Die Löcher 32 in dem Metallstreifen 30, der als Grundplattenverstärkung dient, haben gegenüber den Ankern 14 nur geringes Spiel. Dadurch wird das Aufwölben der Grundplatte 12 in ihrem der Fahrbahn zugekehrten Bereich möglich und ein Verformen der Anker 14 durch die Zugbandwirkung des als Grundplattenverstärkung wirkende Metallstreifens 30 verhindert.A post 10 of a guide 2, which is to be mounted on a structure 4, has a base plate 12, with which the post 10 is welded to its lower end. In the base plate 12, two elongated holes 20 are provided laterally next to the foot point of the post 10, whose longitudinal extent is aligned parallel to the roadway direction. On the base plate 12 is in the region of the slots 20, a metal strip 30 as a base plate reinforcement having holes 32 for the passage of anchors 14, which also pass through the slots 20 in the base plate 12, and are defined in the structure 4. The holes 32 in the metal strip 30, which serves as a base plate reinforcement, have little play with the anchors 14. As a result, the bulging of the base plate 12 in its area facing the road surface is possible and prevents deformation of the armature 14 by the tension band effect of the metal strip 30 acting as a base plate reinforcement.
