Abstract

The longitudinal strips (12, 13) of the rail are applied to the side of the support post (11) which is facing the roadway and the web members (15) are secured on the roadway side to the longitudinal strips (12, 13). The web members (15) - oval-sectioned tubes arranged with the major cross-sectional axis at right angles to the rail - are so clamped by internal retaining elements (151) to the longitudinal strips (12, 13), that, when undergoing a determined lateral impact force, they can pivot around the retaining elements (151) against the longitudinal strips (12, 13). Thus the web members (15) can lie upon another like tiles on a roof. A safety cable (16) can be inserted in each of both the lower and the upper longitudinal strips (13, 12), whereby eyelet screws (142, 144) clamp the cable (16) against strip securing elements (14) and the latter clamp the longitudinal strip (12, 13) against the support posts (11).

Beschrei bungDescription
Technisches GebietTechnical field
Die Erfindung betrifft ein Geländer, und insbeson¬ dere1:- ein Geländer für Straßenbrücken, mit Stützpfosten und Längsgurten, von denen die Füllstäbe getragen werden.The invention relates to a railing, and in particular 1 : a railing for road bridges, with support posts and longitudinal belts, by which the cross bars are carried.
Stand der TechnikState of the art
Geländer für Straßenbrücken besitzen üblicherweise am Brückenunterbau befestigte Stützpfosten, an denen Längs¬ gurte befestigt sind, die ihrerseits die Füllstäbe tragen. Bei einer bekannten Ausführungsform derartiger Geländer sind die Pfosten durch Gurtstücke miteinander verbunden, zwischen die die Füllstäbe gesetzt sind. Bei Straßenbrücken ist in der Regel zur Erhöhung der Verkehrssicherheit durch den oberen Gurt ein Drahtseil gezogen, welches im Falle eines Aufpralls eines von der Fahrbahn abgekommenen Fahr¬ zeugs das Entstehen größerer Öffnungen im Geländer verhin¬ dern soll.Railings for road bridges usually have support posts fastened to the bridge substructure, to which longitudinal straps are fastened, which in turn carry the cross bars. In a known embodiment of such railings, the posts are connected to one another by belt pieces, between which the filler rods are placed. In the case of road bridges, a wire rope is generally pulled through the upper belt in order to increase traffic safety, which is intended to prevent the formation of larger openings in the railing in the event of a crash of a vehicle that has strayed from the road.
Bei Verkehrsunfällen prallt ein von der Fahrbahn abgekommenes Fahrzeug in den meisten Fällen früher oder später gegen einen der Stützpfosten des Geländers, die in der Geländerebene liegen und den Anprall abrupt abbremsen. Größere Fahrzeugschäden und Beschädigungen des Geländers sind die Folge, wobei letztere in vielen Fällen schwer zu beheben sind.In traffic accidents, a vehicle that has strayed from the road will in most cases sooner or later crash into one of the railing's support posts, which lie in the railing plane and abruptly brake the impact. Major vehicle damage and damage to the railing are the result, the latter being difficult to fix in many cases.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Aus¬ führungsform eines insbesondere für Straßenbrücken oder dgl. geeigneten Geländers zu schaffen, bei dem n erster Linie diese Mängel weitgehend vermieden sind und für die Verkehrsteilnehmer eine erhöhte Sicherheit erzielt ist dadurch, daß der Aufprallstoß möglichst am Stützpfosten vorbei gelenkt wird. Die Erfindung bezweckt ferner, die Montage derartiger Geländer zu erleichtern und insbesondere die Reparaturfreundlichkeit zu erhöhen.The invention has for its object to provide an embodiment of a railing which is particularly suitable for road bridges or the like, in which primarily these defects are largely avoided and increased safety is achieved for road users in that the impact impact on the support post if possible is directed past. The invention also aims to facilitate the assembly of such railings and in particular to increase the ease of repair.
Zur Lösung dieser Aufgabe bzw. Aufgaben sieht die Erfindung bei einem insbesondere für Straßenbrücken vorge¬ sehene Geländer mi Stützpfosten und Längsgurten, von denen die Füllstäbe get ragen . werden, in erster Linie vor, daß die Längsgurte an der der Fahrbahn zugewandten Seite der Stütz¬ pfosten angeordnet und die Füllstäbe ebenfalls an der der Fahrbahn zugewandten Seite der Längsgurte befestigt sind. Die durch die Füllstäbe gebildete Geländerebene liegt auf diese Weise in einem Abstand vor den Stützpfosten, so daß der Anprall durch die Füllstäbe und die dahinter liegenden Längsgurte in hohem Maße an den Stützpfosten vorbei gelenkt wird.To achieve this object or objects, the invention provides a railing with support posts and longitudinal belts, of which the filler rods project, in particular for a railing provided for road bridges. are, first of all, that the longitudinal belts are arranged on the side of the support post facing the carriageway and the filler rods are also fastened to the side of the longitudinal belts facing the carriageway. The railing level formed by the filler rods is in this way at a distance in front of the support post, so that the impact by the filler rods and the longitudinal belts behind them is largely directed past the support post.
Diese Maßnahme läßt sich in ihrer Wirkung durch eine besondere Ausbildung der Füllstäbe und insbesondere deren Verbindung mit den Längsgurten dadurch steigern, daß die Füllstäbe selbst und ihre Befestigung an den Längsgurten auf Grund entsprechender Ausbildung eine gewisse Verstell¬ barkeit bzw. Verschwenkbarkeit der Stäbe gegenüber den Längsgurten bei auf die Stäbe ausgeübten seitlichen Stößen gewährleisten. Hierzu können Halteelemente für die Füll¬ stäbe vorgesehen sein, mittels derer letztere gegen die Längsgurte mit einem Anpreßdruck spannbar sind, der eine Verschwenkung der Stäbe gegenüber den Gurten bei über¬ schreiten eines vorgegebenen Seitendrucks quer zur Stab¬ ebene zuläßt. Bei Verwendung von Füllstäben, die als Rohre mit ovalem Querschnitt ausgebildet sind, können die Halte¬ elemente als sich der Rundung des Profils anschmiegende, in den Innenraum einfügbare, stabfδr ige Elemente ausgebildet sein, die durch eine Schraube gegen den Füllstab und den Längsgurt spannbar sind. Hierbei kann man die Halteelemente als zylindrische bzw. halbz lindrische Teile geringer Länge ausbilden, deren Durchmesser der Weite des rohrförmigen Füllstabes entspricht und die eine Gewindebohrung besitzen, in die von der Gurtseite her eine Halteschraube einschraub¬ bar ist. Die Füllstäbe sollten an der Verb ndungsstelle mit den Längsgurten Durchtrittsöf nungen, insbesondere horizon¬ tale Schlitze besitzen, die ein Verschwenken bzw. Verstel¬ len der Füllstäbe gegenüber den Gurten ermöglichen. Es kann ferner zweckmäßig sein, die Breite der Füllstäbe quer zu den Längsgurten und den Abstand der Stäbe zueinander n der Weise aneinander anzupassen, daß die Füllstäbe dachz egel- bzw. schuppenartig aufeinanderlegbar sind.The effect of this measure can be increased by a special design of the filler rods and in particular their connection to the longitudinal belts, in that the filler rods themselves and their attachment to the longitudinal belts have a certain adjustability or pivotability of the rods relative to the longitudinal belts due to the corresponding design in the event of lateral impacts on the bars guarantee. For this purpose, holding elements for the filler rods can be provided, by means of which the latter can be tensioned against the longitudinal belts with a contact pressure which allows the rods to be pivoted relative to the belts when a predetermined side pressure is exceeded transversely to the rod plane. When using filler rods which are designed as tubes with an oval cross-section, the holding elements can be designed as rod-like elements which fit into the curve of the profile and can be inserted into the interior and which can be tensioned by a screw against the filler rod and the longitudinal belt . Here, the holding elements can be designed as cylindrical or semi-cylindrical parts of short length, the diameter of which corresponds to the width of the tubular filler rod and which have a threaded bore into which a retaining screw can be screwed from the belt side. The filler rods should have passage openings, in particular horizontal slots, at the point of connection with the longitudinal belts, which enable the filler rods to be pivoted or adjusted relative to the belts. It may furthermore be expedient to adapt the width of the filler rods transversely to the longitudinal belts and the spacing of the rods to one another in such a way that the filler rods can be laid on top of one another in a roof or scaly manner.
Die Erfindung sieht darüber hinaus ein Geländer, insbesondere der eingangs beschriebenen Art, vor, das zur Erhöhung der Sicherhe t bei Verkehrsunfällen durch ein über mehrere Stützpfosten gespanntes Drahtsei l verstärkt ist, welches in einem Gurt untergebracht ist und bei dem erfin¬ dungsgemäß zwei Sicherheitsdrahtseile vorgesehen sind, von denen das eine auf der Höhe des oberen Längsgurtes und das andere auf der Höhe des unteren Längsgurtes angeordnet ist und beide in erster Lin e in diesen Längsgurten unterge¬ bracht sind. Eine solche Ausbi ldung ist dadurch, daß die Längsgurte beide auf der der Fahrbahn zugewandten Seite der Stützpfosten angeordnet sind, in konstruktiv einfacher Wei¬ se zu bewerkstelligen. Hierbei empfiehlt sich erfindungsge- äß eine gemeinsame Befestigung für das Drahtsei l und den zugehörigen Längsgurt am Stützpfosten, um die Montagekosten niedrig zu halten. In spezieller Ausgestaltung sieht die Erfindung daher für diese Teile ein Befestigungselement vor, durch welches das Drahtseil gegen den Gurt bzw. e n zu dessen Halterung dienendes Trag- oder Stützelement und zu¬ sammen damit gegen den Stützpfosten spannbar ist. Als Befe¬ stigungselement kann hierbei eine mit einem Gewindestutzen versehene Öse dienen, durch die das Drahtseil geführt ist und die mit ihrem Ge indestutzen durch eine insbesondere schlitzförmige Öffnung des Trag- bzw. Stützelements und eine zugehörige Bohrung im Stützpfosten geführt und gegen den Stützpfosten spannbar ist.The invention also provides a railing, in particular of the type described at the outset, which is reinforced to increase safety in traffic accidents by a wire rope stretched over a plurality of support posts, which is accommodated in a belt and provided with two safety wire ropes in accordance with the invention are, one of which is arranged at the height of the upper longitudinal belt and the other at the height of the lower longitudinal belt and both are primarily accommodated in these longitudinal belts. Such training is characterized in that the longitudinal belts both on the side facing the road Support posts are arranged to accomplish in a structurally simple manner. Here, according to the invention, a common fastening for the wire rope and the associated longitudinal belt on the support post is recommended in order to keep the assembly costs low. In a special embodiment, the invention therefore provides a fastening element for these parts, by means of which the wire rope can be tensioned against the belt or support or support element serving to hold it and together therewith against the support post. An eyelet provided with a threaded connector can be used as the fastening element, through which the wire rope is guided and which is threaded with its thread through an especially slit-shaped opening of the supporting or supporting element and an associated hole in the supporting post and can be tensioned against the supporting post .
Kurze Beschreibung der ZeichnungenBrief description of the drawings
In der Zeichnung ist ein Geländer gemäß der Erfin¬ dung, das nsbesondere als Geländer für Straßenbrücken gedacht ist, als Ausführungsbeispiel mit den zum Verständ¬ n s wesentlichen Teilen dargestellt, und zwar zeigt:In the drawing, a railing according to the invention, which is intended in particular as a railing for road bridges, is shown as an exemplary embodiment with the parts essential for understanding, namely:
Fig. 1 einen Teil eines Geländers gemäß der Erfin¬ dung i Aufriß,1 shows part of a railing according to the invention in elevation,
Fig. 2 einen Schnitt etwa nach der Linie 2 - 2 der Fig. 1 undFig. 2 shows a section approximately along the line 2 - 2 of Fig. 1 and
Fig. 3 einen Schnitt etwa nach der Linie 3 - 3 der Fig. 1. Ausfüh rungsart der Erfindung3 shows a section approximately along the line 3 - 3 of FIG. 1. Embodiment of the invention
Das in der Zeichnung dargestellte Geländer wird von Stützpfosten 11 getragen, die mit dem Brückenunterbau fest verbunden sind. An den Stützpfosten 11 sind an der Seite, die der Fahrbahn zugewandt ist, Längsgurte 12 und 13 befe¬ stigt. An diesen Längsgurten sind, wiederum auf der Seite, d e der Fahrbahn zugewandt ist, Füllstäbe 15 befestigt, die in Abständen über die Länge der Längsgurte verteilt sind. Auf Grund einer solchen Ausbildung liegt die durch die Füllstäbe 15 definierte Geländerebene, mit der ein von der Fahrbahn abgekommenes Fahrzeug zunächst in Berührung kommt, in einem gewissen Abstand vor den Stützpfosten und sowohl die Füllstäbe als auch die Längsgurte fangen zunächst das aufprallende Fahrzeug ab und dämpfen den Aufprall, so daß in vielen Fällen ein direkter Kontakt mit den Stützpfosten vermieden werden kann. Hinzu kommt, daß durch die Art der Verbindung der Füllstäbe 15 mit den Längsgurten, die, wie insbesondere aus Fig. 2 ersichtlich ist, be m Aufprall eines Fahrzeuges aus der in stark ausgezogenen Linien dar¬ gestellten Lage in die in gestrichelten Linien dargestellte Lage verschwenkt werden können, der Stoß weich abgefangen und abgelenkt wird. Hierbei kann gegebenenfalls durch ge¬ eignete Bemessung von Abstand der Stäbe zueinander einer¬ seits und Füllstabbreite gemessen quer zu den Längsgurten andererseits erreicht werden, daß sich die Füllstäbe dach¬ ziegelartig aufeinande legen, so daß außer einer Verstär¬ kung auch der Abweiseef ekt erhöht wird. Werden die Füll¬ stäbe, wie dies in Fig. 3 durch die strichpunktierte Linie angedeutet ist, noch vorzugsweise leicht zur Fahrbahnseite hin durchgebogen, wird wegen des größeren Hebelarmes ein Verschwenken aus der in Fig. 2 dargestellten Lage in die gestrichelt gezeichnete erleichtert, und dem Aufprall wird zumindest zu Beginn ein geringerer Widerstand entgegenge¬ setzt, so daß er weicher abgefangen wird. Wie insbesondere aus Fig. 3 ersichtlich ist, dienen zur Befestigung der Längsgurte 12 bzw. 13 an den Stützpfo¬ sten 11 Tragelemente 14, über die die im Profil C-förmig ausgebildeten Längsgurte 12 bzw. 13 geschoben sind." Die Tragelemente 14 können, wie das in Fig. 3 für den unteren Längsgurt dargestellt ist, mit dem Stützpfosten 11 durch eine Schraube 141 verbunden sein. Wird jedoch zur Erhöhung der Sicherheit in einem Längsgurt ein Drahtse l unterge¬ bracht, empfiehlt sich für die Befestigung der Tragelemente 14 an dem Stützpfosten 11 eine Befestigungsart, wie sie in Fig. 3 in Verbindung mit dem oberen Längsgurt 12 darge¬ stellt ist. Hier ist die Befestigungsschraube 141 durch eine Schrauböse 142 ersetzt, durch deren ösenring das Sicherheitsdrahtseil 16 gezogen ist. Der senring liegt- in einem muldenförmigen Sitz 143 des Tragelements 14, der so bemessen ist, daß -das Drahtseil 16 beim Anziehen der auf einen mit dem ösenring verbundenen Gewindestutzen 144 schraubbaren Befestigungsmutter 145 zunächst gegen das Halteelement 14 und zusammen mit diesem' gegen den Stütz¬ pfosten gespannt wird. Beim Festspannen der Tragelemente 14 wird gleichzeitig der Längsgurt 12 bzw. 13 auf dem Stütz- pfosteπ festgeklemmt. Das Tragelement 14 besitzt in Gurt¬ richtung eine Länge, die etwa dem Abstand zwischen zwei Füllstäben entspricht. Wie insbesondere aus Fig. 1 und 2 ersichtlich ist, können die Längsgurte, wenn sie aus zwei oder mehr Teilstücken bestehen, auf einem Tragelement unter Einhaltung einer Dehnungsfuge aneinanderstoßen.The railing shown in the drawing is supported by support posts 11 which are firmly connected to the bridge substructure. Longitudinal belts 12 and 13 are attached to the support posts 11 on the side facing the roadway. Filler rods 15 are fastened to these longitudinal belts, again on the side facing the roadway, which are distributed at intervals over the length of the longitudinal belts. Due to such a design, the railing plane defined by the filler rods 15, with which a vehicle that has strayed from the road initially comes into contact, lies at a certain distance in front of the support post, and both the filler rods and the longitudinal belts initially absorb and impact the impacting vehicle the impact, so that in many cases direct contact with the support posts can be avoided. In addition, the way in which the filler rods 15 are connected to the longitudinal belts, which, as can be seen in particular from FIG. 2, swings when a vehicle strikes from the position shown in solid lines into the position shown in dashed lines can be absorbed and deflected softly. In this case, by appropriate dimensioning of the distance between the bars on the one hand and filler bar width measured transversely to the longitudinal belts on the other hand, the filler bars can be placed on top of one another like a roof tile, so that in addition to reinforcement, the deflection effect is increased . If the filler rods, as indicated by the dash-dotted line in FIG. 3, are still preferably bent slightly towards the side of the roadway, pivoting from the position shown in FIG Impact is countered, at least initially, by a lower resistance, so that it is softer absorbed. As can be seen in particular from FIG. 3, 11 are used for fastening the longitudinal belts 12 and 13 to the support posts 11, over which the longitudinal belts 12 and 13, which are C-shaped in profile, are pushed. " The support elements 14 can, as shown in FIG. 3 for the lower longitudinal belt, be connected to the support post 11 by a screw 141. However, if a wire cable is accommodated in a longitudinal belt to increase safety, it is recommended for the 3 in connection with the upper longitudinal belt 12. Here, the fastening screw 141 is replaced by a screw eyelet 142, through the eyelet ring of which the safety wire rope 16 is pulled senring is located in a trough-shaped seat 143 of the support element 14, which is dimensioned such that the wire rope 16 when tightening the fastening nut 145 which can be screwed onto a threaded connector 144 connected to the eyelet ring, first against the holding element 14 and together with this ' against the support member When the support elements 14 are tightened, the longitudinal belt 12 or 13 is simultaneously on the support tz- pfosteπ clamped. The support element 14 has a length in the belt direction which corresponds approximately to the distance between two filler rods. As can be seen in particular from FIGS. 1 and 2, the longitudinal belts, if they consist of two or more sections, can abut on a support element while maintaining an expansion joint.
Zur Befestigung der Füllstäbe 15 an den Längsgurten 12 und 13 sind, wie aus Fig. 3 in Verbindung mit Fig. 2 ersichtlich ist, zylindrische Befestiguπgselemente 151 vor¬ gesehen, die in die als im Querschnitt ovale Rohre ausge¬ bildeten Füllstäbe von den Stabenden her eiπsetzbar sind, wobei der Durchmesser der Befes igungselemente so gewählt sein sollte, daß sie sich an die Rundung der Füllstäbe an¬ schmiegen und sich in dem Rohr m t le chtem Druck festklem¬ men. Die Befestigungselemente 151, die auch halbzylindri¬ sche Form besitzen können, s nd mit einer Gewindebohruπg versehen, n die von der Gurtseite her eine Schraube 152 einschraubbar ist, mittels der der zugehörige Füllstab fest gegen den Gurt spannbar ist. Der Füllstab besitzt auf der Höhe der Schraube 152 einen Schlitz 153, der es ermöglicht, daß sich der Füllstab 15 um die Achse des zylindrischen Be¬ festigungselements verschwenken kann, wenn ein stärkerer Stoß auftritt, wie dies in Fig. 2 durch die gestrichelten Linien angedeutet ist. Das zylindrische Befestigungselement wirkt in einem solchen Falle etwa wie ein Zapfenlager. Am oberen Ende ist der Füllstab 15 mit dem Längsgurt 12 in entsprechender Weise verbunden und die entsprechenden Tei le sind daher mit den gleichen Bezugszeichen versehen. Die Füllstäbe sind an ihren unteren Enden durch Einsatzstücke 154 verschlossen, während die oberen Enden durch ein Hand¬ laufprofi l 155 abgedeckt sind. For fastening the filler rods 15 to the longitudinal belts 12 and 13, as can be seen from FIG. 3 in conjunction with FIG. 2, cylindrical fastening elements 151 are provided, which extend from the rod ends into the filler rods formed as oval cross-section tubes can be used, the diameter of the fastening elements being chosen in this way should be that they nestle against the rounding of the filler rods and clamp themselves in the tube with light pressure. The fastening elements 151, which can also have a semi-cylindrical shape, are provided with a threaded hole, n from which a screw 152 can be screwed in from the belt side, by means of which the associated filler rod can be firmly clamped against the belt. The filler rod has a slot 153 at the level of the screw 152, which enables the filler rod 15 to pivot about the axis of the cylindrical fastening element when a stronger impact occurs, as indicated by the broken lines in FIG. 2 is. In such a case, the cylindrical fastening element acts approximately like a journal bearing. At the upper end, the filler rod 15 is connected to the longitudinal belt 12 in a corresponding manner and the corresponding Tei le are therefore provided with the same reference numerals. The filler rods are closed at their lower ends by inserts 154, while the upper ends are covered by a handrail profile 155.
