Die Anlenkung der Zugstäbe und deren Längenveränderlichkeit dient dem Zweck, das Windverbandsystem montieren zu können, nachdem zunächst der Druckstab mit der zugeordneten Lasche verbunden ist und über die beiden Zugstäbe infolge der Verkürzung die entsprechende Druckkraft in den Druckstab eingeleitet wird. Dieses System ist nicht geeignet als Basis für unterschiedliche Systemkonstruktionen zu dienen, nicht zuletzt deshalb, weil kein verfahrbarer Schlitten vorgesehen ist. From NL-A-8 500 510 is a wind dressing system with pull and Pressure rods known. Three engage on the respective connection element Members of which the two diagonal members function as Have tension rods. The two tension rods are variable in length trained and articulated grip on the respective connector on. The pressure rod is rigidly connected to the connecting element and unchangeable in length. The linkage of the tension rods and their variability in length serves the purpose of the wind dressing system to be able to mount after the pressure rod is connected to the assigned tab and via the two tension rods due to the shortening the corresponding Pressure force is introduced into the pressure rod. This system is not suitable as a basis for different system designs to serve, not least because no movable one Sledge is provided.

Aus der US-A-3 564 783 ist ein Tragsystem zur Verwendung im Bereich der Verkehrstechnik bekannt, bei dem mit einem Anschlußelement eine Vielzahl von Stäben fest verbunden sind, die weder längenveränderlich sind noch gelenkig am Anschlußelement angreifen. Das Anschlußelement ist als zweiteilige Schelle ausgebildet, die an einer definierten Stelle des jeweiligen Haupttragteiles mit diesem verschraubt ist. Unterschiedliche Tragsystemkonstruktionen können durch diese Ausbildung der Verbindung der Stäbe mit dem Anschlußelement und dessen Verbindung mit dem Haupttragteil nicht bewerkstelligt werden, ein Ausgleich von Toleranzen ist gleichfalls nicht möglich.From US-A-3 564 783 a support system for use in the Known area of traffic engineering, in which with a connecting element a large number of rods are firmly connected, neither variable in length are still articulated on the connecting element attack. The connecting element is a two-part clamp trained at a defined point of each Main support part is screwed to this. Different Support system constructions can be achieved through this training Connection of the rods to the connecting element and its connection not be accomplished with the main supporting part Compensation of tolerances is also not possible.

Es ist Aufgabe der vorliegenden Erfindung, ein Tragsystem der im Oberbegriff des Patentanspruches 1 genannten Art so weiter zu bilden, daß mit standardisierten Bauteilen des Tragsystems unterschiedliche Tragsystemkonstruktionen dargestellt werden können, insbesondere unter Berücksichtigung der Toleranzeinflüsse der das Tragsystem bildenden Bauteile.It is an object of the present invention to provide a support system Preamble of claim 1 mentioned type so on form that with standardized components of the support system different support system designs are shown can, especially taking into account the influence of tolerance of the components forming the support system.

Gelöst wird die Aufgabe durch ein Tragsystem mit den Merkmalen des Patentanspruches 1.The task is solved by a support system with the characteristics of claim 1.

Der Ausgangspunkt der vorliegenden Erfindung ist darin zu sehen, das in Fachwerkbauweise gestalte Tragsystem so auszubilden, daß die Haupttragteile und die Tragelemente nicht miteinander verschweißt, sondern über die Befestigungsmittel miteinander verbunden sind, insbesondere durch Verschrauben. Dies ermöglicht es, das Tragsystem aus den einzelnen Bestandteilen entsprechend den Anforderungen des Einzelfalles zu montieren, wobei von standardisierten Ausgangsbauteilen ausgegangen werden kann, beispielsweise normierten Längen der Haupttragteile, normierten Gestaltungen der Tragelemente, das heißt auch normierten Gestaltungen der Stäbe. Die schwenkbare Anlenkung der Stäbe an den Anschlußelementen ermöglicht es, die unterschiedlichsten statisch gewünschten Angriffswinkel der Stäbe an den Anschlußelementen zu erzeugen, womit die Konstruktionen beliebig gedrängt bzw. beliebig auseinandergezogen gestaltet werden können. The starting point of the present invention is to be seen in to design the support system designed in the half-timbered construction so that the main supporting parts and the supporting elements are not together welded, but via the fasteners together are connected, in particular by screwing. this makes possible it, the support system from the individual components accordingly to assemble the requirements of the individual case, whereby from standardized output components can be assumed for example standardized lengths of the main supporting parts, standardized Designs of the support elements, that means also standardized Bar designs. The pivotable linkage of the rods the connecting elements allow the most varied statically desired angle of attack of the rods on the connecting elements to generate with what the constructions arbitrarily be pushed or pulled apart as desired can.

Der Vorteil der erfindungsgemäßen Gestaltung ergibt sich strenggenommen durch drei Merkmale: Einerseits die Längenverstellbarkeit der Stäbe, andererseits die gelenkige Lagerung der Stäbe im Anschlußelement und andererseits die Gestaltung des Anschlußelementes als Schlitten, der relativ zum zugeordneten Haupttragteil verschiebbar und mit diesem fest verbindbar ist. Durch dieses Zusammenwirken ist die Flexibilität bei der Bildung von Tragsystemkonstruktionen unter Berücksichtigung der Toleranzeinflüsse der Bauteile gewährleistet. Alle Stäbe sind im Anschlußelement schwenkbar gelagert, womit variable Winkel der Stäbe dargestellt werden können, mit der Konsequenz der Änderung der Gurtabstände bei Verwendung derselben Stäbe. Bei einer Änderung der Gurtabstände sind die Positionen der Schlitten entsprechend zu korrigieren, was aufgrund der Verfahrbarkeit ohne weiteres geschehen kann. Ein eventueller Toleranzausgleich kann dann durch die Längenveränderung der Stäbe vorgenommen werden. Aufgrund der gelenkigen Lagerung der Stäbe können diese bei der Montage des Tragsystems eingeschwenkt werden. Beim montierten Tragsystem können einzelne Stäbe aufgrund deren Längenveränderlichkeit demontiert bzw. montiert werden.The advantage of the design according to the invention results Strictly speaking, it has three features: On the one hand, the length adjustability the rods, on the other hand the articulated mounting of the Rods in the connecting element and on the other hand the design of the Connection element as a carriage, which is relative to the associated Main support part is slidable and can be firmly connected to it. Through this interaction there is flexibility in education of support system constructions taking into account the influence of tolerance of the components guaranteed. All bars are in Connection element pivotally mounted, which variable angle of Bars can be represented with the consequence of the change the belt spacing when using the same rods. At a Changing the belt spacing are the positions of the sledges Correct accordingly what is due to the movability can easily happen. A possible tolerance compensation can then be made by changing the length of the bars become. Due to the articulated storage of the rods, these can be pivoted in when mounting the support system. At the assembled support system can individual bars due to their Length variability can be disassembled or assembled.

Die Haupttragteile und/oder die Tragelemente bestehen bevorzugt aus Aluminium oder einer Aluminiumlegierung, gegebenenfalls unter Verwendung von Befestigungsmitteln aus Stahl. Das genannte Material gewährleistet eine hinreichende Stabilität des Tragsystems, bei einfacher Montage aufgrund des relativ niedrigen Gewichtes der einzelnen Komponenten. Es ist aber auch denkbar, die Konstruktion als Aluminium-Edelstahl-Kombination auszuführen oder als Aluminiumstahlkonstruktion, wobei es sich insbesondere um verzinkten Stahl handelt.The main supporting parts and / or the supporting elements preferably consist made of aluminum or an aluminum alloy, if appropriate using steel fasteners. The said Material ensures sufficient stability of the support system, with simple assembly due to the relatively low Weight of the individual components. But it is also conceivable the construction as an aluminum-stainless steel combination or as an aluminum steel structure, it being in particular is galvanized steel.

Das Tragsystem kann beispielsweise als Brücke, insbesondere Schilderbrücke, Mautbrücke oder dergleichen ausgebildet sein, wobei jeder Fachwerkträger dreidimensional gestaltet ist. Es ist gleichfalls denkbar, das Tragsystem als Schilderständer zu verwenden, wobei das Schild die Verbindung zwischen zwei zweidimensionalen Fachträgern darstellt. The support system can, for example, as a bridge, in particular Sign bridge, toll bridge or the like can be formed, each truss is designed three-dimensionally. It is it is also conceivable to use the support system as a sign stand use, the shield being the connection between two represents two-dimensional specialist bodies.

Eine bevorzugte Weiterbildung der Erfindung sieht vor, daß mindestens zwei abgewinkelt zueinander angeordnete Fachwerkträger mittels einer Eckverbindung verbunden sind, wobei die eigentliche Verbindung im Bereich der beiden jeweiligen, eine Ecke bildenden Haupttragteile der Fachwerkträger mittels eines Winkelelementes erfolgt. Haupttragteile unterschiedlicher Fachwerkträger werden damit paarweise mittels Winkelelementen verbunden. Es ist somit im Bereich der Ecken der jeweiligen Verbindung keine Schweißverbindung erforderlich, sondern es erfolgt dort die Verbindung der Haupttragteile über Verbindungselemente in Art der Winkelelemente.A preferred development of the invention provides that at least two trusses arranged at an angle to each other are connected by means of a corner connection, the actual connection in the area of the respective two, one Main part of the truss girders forming a corner using a Angle element takes place. Main supporting parts of different Truss girders are made in pairs using angle elements connected. It is therefore in the area of the corners of each Connection no weld connection required, but it the main supporting parts are connected there via connecting elements in the way of the angular elements.

Insbesondere die Gestaltung des jeweiligen Haupttragteiles durch mehrere Haupttragteilelemente ermöglicht es, lange Fachwerkträger aus standardisierten Bauteilen zu bilden, das heißt nicht nur aus standardisierten Haupttragteilelementen, sondern auch aus standardisierten Stäben und gegebenenfalls erforderlichen standardisierten Anschlußelementen sowie Winkelelementen. Die wenigen unterschiedlichen, für den Bau des Tragsystems erforderlichen Bauteile sind damit unkompliziert verfügbar und es kann das Tragsystem auf einfache Art und Weise beim Hersteller in Baugruppen vormontiert werden, so daß die Baugruppen vor Ort nur noch endmontiert werden müssen. Bei einer teilweisen Beschädigung des Tragsystems durch Fremdeinwirkung können beschädigte Teile auf einfache Art und Weise gegen neue Teile ersetzt werden. Auch besteht die Möglichkeit, alle Bauteile des Tragsystems komplett wieder zu verwenden bzw. bestehende Tragsysteme problemlos auf andere Spannweiten unter Verwendung derselben Bauteile umzubauen.In particular, the design of the respective main supporting part several main load-bearing elements allow long trusses to form from standardized components does not mean that only from standardized main load-bearing elements, but also from standardized rods and any necessary standardized connection elements as well as angle elements. The few different, necessary for the construction of the support system Components are thus easily available and it can the support system in a simple manner at the manufacturer in Assemblies are preassembled so that the assemblies only on site still need to be assembled. In the event of partial damage of the support system due to external influences can be damaged Parts easily replaced with new parts become. There is also the possibility of all components of the support system completely reusable or existing support systems easily to other spans using the same Modify components.

Die Erfindung schlägt damit ein Tragsystem vor, das aus weitgehend standardisierten Bauteilen besteht, womit weitgehend beliebig gestaltete Gebilde montiert werden können. Dies erlaubt einen universellen Einsatz des Tragsystems, das bei Ausbildung als dreidimensionales Gebilde, insbesondere für Kragarme und Brücken verwendet wird, wobei diese Begriffe allumfassend verstanden werden. Bei Verwendung der Brücke im Zusammenhang mit der Regelung und Erfassung von Verkehr ist an eine Ausbildung der Brücke als Schilderbrücke oder aber auch als Mautbrücke gedacht, das heißt, sie dient dem Zweck, unter der Brücke hindurchfahrende Fahrzeuge zu erfassen, um zu einer Ermittlung einer fahrstreckenbezogenen Gebühr für die Nutzung des Verkehrsweges zu gelangen. In diesem Sinne ermöglicht die Gestaltung des Tragsystems die Brücken so zu konzipieren, daß sie auch begehbar sind. Dies kann auf einfache Art und Weise dadurch erfolgen, daß in der beschriebenen Fachwerkbauweise begehbare Zonen der Brücken aus den Haupttragteilen und den diese verbindenden Tragelementen gestaltet werden. Die begehbaren Zonen können dabei innerhalb des Fachwerkes geschaffen werden, indem die Ober- und Untergurte des horizontalen Fachwerkträgers entsprechend weit beabstandet zueinander angeordnet werden. The invention thus proposes a support system that largely consists of standardized components, with which largely any shape can be assembled. This allows universal use of the support system, which is used in training as a three-dimensional structure, especially for cantilever arms and Bridges is used, these terms being all encompassing be understood. When using the bridge in connection with The regulation and recording of traffic is in training the bridge as a gantry bridge or as a toll bridge thought, that is, it serves the purpose under the bridge vehicles passing through to capture an investigation a route-related fee for the use of the traffic route to get. In this sense, the design of the Support systems to design the bridges so that they can also be walked on are. This can be done in a simple manner in that Zones accessible in the half-timbered construction described Bridges from the main load-bearing parts and the connecting parts Support elements can be designed. The walkable zones can be created within the framework by the Upper and lower chords of the horizontal truss accordingly be spaced far apart.

Das in Figur 1 gezeigte Tragsystem ist im wesentlichen durch drei Fachwerkträger gebildet, nämlich die vertikalen Fachwerkstützen 1 und 2 und die mit diesen verbundene, horizontale Fachwerkbrücke 3, an der, mit strichlierten Linien verdeutlicht, ein Schild 4 in nicht näher gezeigter Art und Weise verbunden ist, die die gleichfalls nicht verdeutlichte Verkehrs- bzw. Wegweiseinrichtung beinhaltet.The support system shown in Figure 1 is essentially through three truss girders formed, namely the vertical truss columns 1 and 2 and the horizontal associated with them Truss bridge 3, on which, illustrated by dashed lines, a shield 4 connected in a manner not shown which is the traffic or Signpost facility includes.

Die beiden Fachwerkstützen 1 und 2 sowie die Fachwerkbrücke 3 sind vom Grundsatz her identisch aufgebaut, das heißt sie weisen identische, sich über deren gesamte Länge erstreckende Haupttragteile 5 sowie identische Stäbe 20, 28 und identische Anschlußelemente 27 auf. Im jeweiligen Fußbereich weist die Fachwerkstütze 1 bzw. 2 eine mit dieser verbundene Lagerplatte 8 auf und es sind die beiden Enden der Fachwerkbrücke 3 mit einer Riegelauflagerung, die gleichfalls eine Platte 9 umfaßt, versehen. Die Fachwerkbrücke 3 kann beispielsweise, wie zur Fachwerkstütze 1 gezeigt, unmittelbar in dieser gelagert sein, oder aber auch, wie zur Fachwerkstütze 2 gezeigt, über eine Lagerplatte 10, die mit der Fachwerkstütze 2 verbunden ist.The two truss columns 1 and 2 as well as the truss bridge 3 are constructed identically in principle, that is, they point identical main supporting parts, which extend over their entire length 5 and identical rods 20, 28 and identical Connection elements 27 on. In the respective foot area, the Truss column 1 or 2 a bearing plate connected to this 8 on and there are the two ends of the truss bridge 3 a bar support, which also comprises a plate 9, Mistake. The truss bridge 3 can, for example, how Truss support 1 shown, be mounted directly in it, or, as shown for the truss support 2, via a Bearing plate 10, which is connected to the truss 2.

Wesentlich ist für die vorliegende Erfindung die besondere Gestaltung der durch die Fachwerkstützen 1 und 2 und die Fachwerkbrücke 3 dargestellten Fachwerkträger. Wegen der vom Grundsatz her identischen Ausgestaltung der Fachwerkstützen 1 und 2 und der Fachwerkbrücke 3 bezieht sich die nachfolgende detaillierte Beschreibung der erfindungswesentlichen Merkmale auf die der Fachwerkbrücke 3, entsprechend gelten die Ausführungen auch bezüglich der Gestaltung der Fachwerkstützen 1 und 2.The special is essential for the present invention Design of the truss columns 1 and 2 and the Truss bridge 3 shown truss. Because of the Basically identical design of the truss columns 1 and 2 and the truss bridge 3 refers to the following detailed description of the features essential to the invention to that of the truss bridge 3, the explanations apply accordingly also regarding the design of the truss columns 1 and 2.

Die Fachwerkbrücke 3 besteht aus vier, ein Rechteck aufspannenden Haupttragteilen 5, wobei jedes Haupttragteil 5 aus zwei Haupttragteilelementen 5' und 5'' zusammengesetzt ist. Die im Obergurt der Fachwerkbrücke 3 angeordneten Haupttragteile sind, wie insbesondere der Figur 2 zu entnehmen ist, mit den Bezugsziffern 5a und 5b bezeichnet, während die im Untergurt, gemäß der Darstellung in Figur 3, angeordneten Haupttragteile mit den Bezugszeichen 5c und 5d bezeichnet sind.The truss bridge 3 consists of four, spanning a rectangle Main support parts 5, each main support part 5 of two Main support elements 5 'and 5' 'is composed. The in The upper chord of the truss bridge 3 are main supporting parts, as can be seen in particular in Figure 2, with the reference numerals 5a and 5b, while those in the lower flange, according to the representation in Figure 3, arranged main support parts with the Reference numerals 5c and 5d are designated.

Wie insbesondere den Figuren 6 und 7 zu entnehmen ist, ist das jeweilige Haupttragteil 5 als Strangpreßprofil ausgebildet, das mit drei sich über dessen gesamte Länge verlaufenden Führungsschienen 11, 12 und 13 versehen ist. Die jeweilige Führungsschiene ist als hinterschnittene Nut 14 ausgebildet, die Führungsschienen 11, 12 und 13 sind jeweils, auf die benachbarte Führungsschiene bezogen in einem Winkel von 45° zueinander angeordnet. Das Strangprofil weist einen grundsätzlich rohrförmigen Profilabschnitt 15 auf, an den sich die die Führungsschienen 11 bis 13 enthaltenden Profilansätze 16 anschließen. Um beliebig lange Haupttragteile 5 aus Standardlängen bilden zu können, sind in die Rohröffnungen 17 der jeweiligen Profilabschnitte 15 der Standardlängen aufweisenden Haupttragteilelemente 5' und 5" Verbindungsrohre 18 eingesteckt, die damit benachbarte Haupttragteilelemente 5' und 5" desselben Haupttragteiles in deren Endbereichen durchsetzen. Schrauben 19, die zugeordnete Bohrungen in den Haupttragteilelementen 5' und 5" sowie Gewindebohrungen im zugeordneten Verbindungsrohr 18 durchsetzen, stellen eine sichere Verbindung der Haupttragteilelemente 5' und 5" des jeweiligen Haupttragteiles 5 sicher.As can be seen in particular from FIGS. 6 and 7, this is respective main support part 5 formed as an extruded profile, the with three guide rails running along its entire length 11, 12 and 13 is provided. The respective guide rail is formed as an undercut groove 14, the Guide rails 11, 12 and 13 are, respectively, on the adjacent one Guide rail related to each other at an angle of 45 ° arranged. The extruded profile has a basically tubular shape Profile section 15 on which the guide rails Connect profile lugs 16 containing 11 to 13. Around Main supporting parts 5 of any length from standard lengths form can, are in the pipe openings 17 of the respective profile sections 15 of the standard length main support members 5 'and 5 "connecting tubes 18 inserted, so that Adjacent main support member elements 5 'and 5 "of the same main support member enforce in their end areas. Screws 19 that assigned holes in the main support elements 5 'and 5 " as well as threaded bores in the associated connecting tube 18 enforce, make a secure connection of the main support elements 5 'and 5 "of the respective main supporting part 5 safely.

Positioniert werden die Haupttragteile 5 der Fachwerkbrücke 3 so zueinander, daß die Führungsschienen 11 und 12 zu den benachbarten Haupttragteilen 5 weisen, während die Führungsschiene 13 zum diagonal zu diesem Haupttragteil 5 angeordneten Haupttragteil 5 gerichtet ist.The main supporting parts 5 of the truss bridge 3 are positioned in this way to each other that the guide rails 11 and 12 to the neighboring Main support parts 5 have, while the guide rail 13th to the main support part arranged diagonally to this main support part 5 5 is directed.

Die diagonale Verbindung der Haupttragteile 5 erfolgt unmittelbar mittels einer Vielzahl mit dem jeweiligen, interessierenden Haupttragteil 5 verbundenen Stäben 20, wie es für den Anschluß eines solchen Stabes 20 am zugeordneten Haupttragteil 5 in Figur 7 gezeigt ist. Der Stab 20 ist als Rohr ausgebildet, das im Bereich seiner beiden Enden über Befestigungsmittel 21 mit dem Haupttragteil 5 verbunden ist. Die Befestigungsmittel umfassen eine Schraube 22 und eine Hülse 23 mit gleichgerichtetem Innen- und Außengewinde. Die Schraube 22, die entsprechend der Gestaltung in Figur 7 mit einem Hammerkopf 24 versehen ist, wird mit diesem in die der Führungsschiene 13 zugeordnete Nut 14 eingesetzt und der Schraubenbolzen 25 in das Innengewinde der Hülse 23 eingeschraubt.

The Arrangement of the rods connecting the diagonal main support parts 5 20 is not shown in FIG. 1 for drawing reasons, however in the representation of FIG. 4.

Die Führungsschienen 11 und 13 dienen der Aufnahme der besonders gestalteten Anschlußelement 27, die nur bezüglich der Führungsschiene 11 verdeutlicht sind. Bei der Verbindung benachbarter, nicht diagonal angeordneter Haupttragteile 5 sind Stäbe 28 damit nicht unmittelbar mit den zugeordneten Haupttragteilen 5 verbunden, sondern mit den Anschlußelementen 27, die ihrerseits mit den Haupttragteilen 5 verbunden sind. Wie insbesondere der Darstellung der Figuren 5 und 7 zu entnehmen ist, ist das jeweilige Anschlußelement 27 als blockartiges Bauteil ausgebildet, das eine ebene Auflagefläche 29 aufweist und, auf dessen Längserstreckung bezogen, im Bereich jedes seiner beiden Enden mit einer sich senkrecht zur Auflagefläche 29 erstreckenden Durchgangsbohrung 30 versehen ist. Befestigt wird das jeweilige Anschlußelement 27 mit der Führungsschiene 11 bzw. 12 über Befestigungsmittel 41 die zwei Schrauben 31 mit Hammerkopf 32 umfassen, die entsprechend der Schraube 22 gestaltet sind. Die Schrauben 31 werden in die der Führungsschiene 11 bzw. 12 zugeordnete Nut 14 eingesetzt und es durchsetzt der jeweilige Schraubenbolzen 33 die zugeordnete Durchgangsbohrung 30. Auf die jeweilige Schraube 31 ist eine Mutter 34 aufgeschraubt. Der zentralere Bereich des jeweiligen Anschlußelementes 27 kann zusätzlich mit einer Bohrung 35 versehen sein, die mit einer nachträglich in das Haupttragteil 5 eingebrachten Bohrung 36 fluchtet; die beiden Bohrungen durchsetzt ein Kerbstift 37.The guide rails 11 and 13 serve to accommodate the particularly designed connector 27, only with respect to the guide rail 11 are illustrated. When connecting neighboring, main supporting parts 5 not arranged diagonally are rods 28 not directly with the assigned main bearing parts 5 connected, but with the connecting elements 27, which in turn are connected to the main supporting parts 5. How in particular 5 and 7 can be seen, that is respective connection element 27 is formed as a block-like component, which has a flat bearing surface 29 and, on the Related to longitudinal extension, in the area of each of its two ends with a perpendicular to the support surface 29 extending Through hole 30 is provided.
