Description
Die Erfindung betrifft eine längliche Spanneinheit umfassend einen Mantel, der einen Innenraum umschließt, und eine Mehrzahl von Spannelementen, welche in Längsrichtung der Spanneinheit verlaufen und in dem Innenraum des Mantels aufgenommen sind.The invention relates to an elongated clamping unit comprising a jacket which encloses an interior space, and a plurality of clamping elements which run in the longitudinal direction of the clamping unit and are received in the interior of the jacket.
Überwiegend aus gestalterischen Gründen ist es seit einiger Zeit in Mode gekommen, längliche Spanneinheiten, beispielsweise Schrägseile, wie sie bei Schrägseilbrücken, Türmen und dergleichen Bauwerken zum Einsatz kommen, zu beleuchten. Zunächst wurden die Bauwerke mit Strahlern indirekt beleuchtet. Dies hatte jedoch den Nachteil, dass nur ein geringer Bruchteil des ausgestrahlten Lichts von dem jeweiligen Bauwerk bzw. dessen Spanneinheiten reflektiert wurde. Daher mussten entsprechend stark dimensionierte Lichtquellen vorgesehen werden, was aufgrund des damit einhergehenden Stromverbrauchs entsprechend hohe Betriebskosten nach sich zog. Zudem konnte der beabsichtigte gestalterische Effekt nicht in dem gewünschten Maße erzielt werden.Mainly for design reasons, it has become fashionable for some time to illuminate elongated tensioning units, for example stay cables, as they are used in cable-stayed bridges, towers and similar structures. Initially, the structures were indirectly illuminated with spotlights. However, this had the disadvantage that only a small fraction of the emitted light was reflected by the respective building or its clamping units. Therefore, light sources with correspondingly large dimensions had to be provided, which resulted in correspondingly high operating costs due to the associated power consumption. In addition, the intended design effect could not be achieved to the desired extent.
Zur Lösung dieses Problems wurde vorgeschlagen, die Leuchtelemente unmittelbar an den Spanneinheiten anzuordnen. So ist es beispielsweise aus der
Darüber hinaus ist es aus der
Aufgabe der Erfindung ist es, hier Abhilfe zu schaffen.The object of the invention is to provide a remedy here.
Diese Aufgabe wird erfindungsgemäß durch eine längliche Spanneinheit der eingangs genannten Art gelöst, bei welcher der Mantel an wenigstens einer Umfangsposition eine in seinen Innenraum hinein ragende Vertiefung aufweist, in der wenigstens eine elektrische Funktionseinheit, beispielsweise wenigstens eine Beleuchtungseinheit, sowie wenigstens eine Anschlussleitung für die wenigstens eine elektrische Funktionseinheit aufgenommen ist.This object is achieved according to the invention by an elongated tensioning unit of the type mentioned at the outset, in which the jacket has a recess protruding into its interior at at least one circumferential position, in which at least one electrical functional unit, for example at least one lighting unit, and at least one connection line for the at least an electrical functional unit is included.
Die Erfinder haben erkannt, dass die Anordnung der Spannelemente im Innenraum des Mantels beliebig gewählt werden kann. Ausschlaggebend ist nur die für das jeweils geforderte Tragvermögen der Spanneinheit erforderliche Anzahl der Spannelemente. Dies ermöglicht es, innerhalb des für die aerodynamischen Eigenschaften der Spanneinheit verantwortlichen äußeren Umrisses des Mantels wenigstens eine in den Innenraum hinein ragende Vertiefung vorzusehen, in der die elektrische Funktionseinheit aufgenommen werden kann. Vorteilhafterweise können die Spannelemente erfindungsgemäß auch in Teilflächen der Querschnittsfläche des Innenraums des Mantels angeordnet sein, die in radialer Richtung auf der gleichen Höhe, in Umfangsrichtung jedoch zwischen zwei einander benachbarten Seitenbegrenzungswandungen einer Vertiefung oder mehrerer Vertiefungen gelegen sind.The inventors have recognized that the arrangement of the clamping elements in the interior of the jacket can be selected as desired. Only the number of clamping elements required for the required load-bearing capacity of the clamping unit is decisive. This makes it possible to provide within the outer contour of the jacket, which is responsible for the aerodynamic properties of the tensioning unit, at least one recess which projects into the interior and in which the electrical functional unit can be accommodated. Advantageously, according to the invention, the tensioning elements can also be arranged in partial areas of the cross-sectional area of the interior of the jacket, which are situated at the same height in the radial direction, but between two adjacent side walls of a recess or several recesses in the circumferential direction.
Insgesamt weist die Querschnittsfläche des Innenraums eine von einer Kreisform verschiedene Gestalt auf.Overall, the cross-sectional area of the interior has a shape different from a circular shape.
Da die Wandstärke des Mantels im Wesentlichen gleich bleiben kann, erhöht sich die Querschnittsfläche des Mantels und damit der gesamten Spanneinheit nur geringfügig, nämlich gerade mal um die Querschnittsfläche, welche für die Anordnung der wenigstens einen die elektrische Funktionseinheit aufnehmenden Vertiefung erforderlich ist. Darüber hinaus reduziert sich durch die erfindungsgemäße Lösung die Anzahl der zur Anordnung der wenigstens einen elektrischen Funktionseinheit erforderlichen Bauteile, was sich vorteilhaft auf die Gestehungskosten auswirkt.Since the wall thickness of the jacket can remain essentially the same, the cross-sectional area of the jacket and thus of the entire clamping unit increases only slightly, namely just by the cross-sectional area required for the arrangement of the at least one recess accommodating the electrical functional unit. In addition, the solution according to the invention reduces the number of components required for arranging the at least one electrical functional unit, which has an advantageous effect on the production costs.
Aufgrund der Tatsache, dass die wenigstens eine Vertiefung in den Innenraum des Mantels hinein ragt, kann der Mantel frei von Hohlräumen ausgebildet sein, vorteilhafterweise frei von Hohlräumen, welche frei von darin angeordneten Spannelementen sind. Da somit das zur Ausbildung derartiger Hohlräume erforderliche Mantelmaterial eingespart werden kann, kann die erfindungsgemäße Spanneinheit kostengünstiger hergestellt werden.Due to the fact that the at least one recess protrudes into the interior of the jacket, the jacket can be designed free from cavities, advantageously free from cavities which are free from tensioning elements arranged therein. Since the jacket material required to form such cavities can thus be saved, the clamping unit according to the invention can be manufactured more cost-effectively.
Wie vorstehend bereits angedeutet, kann die wenigstens eine elektrische Funktionseinheit vorteilhafterweise eine Beleuchtungseinheit sein. Grundsätzlich ist es jedoch auch denkbar, andere Arten von elektrischen Funktionseinheiten vorzusehen, beispielsweise Sensoreinheiten.As already indicated above, the at least one electrical functional unit can advantageously be a lighting unit. In principle, however, it is also conceivable to provide other types of electrical functional units, for example sensor units.
Unabhängig von der Art der elektrischen Funktionseinheit(en) kann eine Mehrzahl von Vertiefungen über den Umfang des Mantels verteilt angeordnet sein. Um im Fall von Beleuchtungseinheiten gewährleisten zu können, dass die Spanneinheit aus allen Richtungen gut zu sehen ist, wird vorgeschlagen, dass wenigstens drei Vertiefungen über den Umfang des Mantels verteilt angeordnet sind.Regardless of the type of electrical functional unit (s), a plurality of depressions can be arranged distributed over the circumference of the jacket. In order to be able to ensure in the case of lighting units that the tensioning unit can be clearly seen from all directions, it is proposed that at least three depressions are arranged distributed over the circumference of the jacket.
An dieser Stelle sei der Vollständigkeit halber darauf hingewiesen, dass auch die erfindungsgemäße Spanneinheit ein Spannseil sein kann, beispielsweise ein Schrägseil, wie es bei Schrägseilbrücken, Türmen und dergleichen Bauwerken zum Einsatz kommt.At this point, for the sake of completeness, it should be pointed out that the tensioning unit according to the invention can also be a tensioning cable, for example a stay cable, as is used in cable-stayed bridges, towers and similar structures.
Auch wenn eine Mehrzahl von elektrischen Funktionseinheiten vorgesehen ist, die in Längsrichtung der Spanneinheit lediglich an vorbestimmten Positionen angeordnet sind, ist es vorteilhaft, wenn sich die wenigstens eine Vertiefung zumindest über einen vorbestimmten Teil der Länge der Spanneinheit, vorzugsweise im Wesentlichen über die gesamte Länge der Spanneinheit, erstreckt. Grundsätzlich ist es also denkbar die elektrischen Funktionseinheiten nur in einem Längenabschnitt oder mehreren voneinander getrennten Längenabschnitten der Spanneinheit vorzusehen.Even if a plurality of electrical functional units is provided, which are arranged in the longitudinal direction of the tensioning unit only at predetermined positions, it is advantageous if the at least one recess extends at least over a predetermined part of the length of the tensioning unit, preferably essentially over the entire length of the Clamping unit, extends. In principle, it is therefore conceivable to provide the electrical functional units only in one length section or in several length sections of the tensioning unit that are separate from one another.
In Weiterbildung der Erfindung wird vorgeschlagen, dass die Vertiefung eine Deckenwandung aufweist, die in Verlängerung der Umfangserstreckung der äußeren Oberfläche des Mantels verläuft. Mit anderen Worten verläuft die Deckenwandung im Wesentlichen längs der Hüllfläche des Mantels. Durch diese Weiterbildung kann vermieden werden, dass die wenigstens eine elektrische Funktionseinheit über die äußere Oberfläche des Mantels hinaus ragt. Somit kann sie keine erhöhte Angriffsfläche für Wind und/oder Wetter bieten.In a further development of the invention, it is proposed that the recess have a top wall which extends as an extension of the circumferential extension of the outer surface of the jacket. In other words, the top wall runs essentially along the envelope surface of the jacket. This development can prevent the at least one electrical functional unit from protruding beyond the outer surface of the jacket. Thus, it cannot offer an increased surface area for wind and / or weather.
Sind die elektrischen Funktionselemente nur an bestimmten Positionen der Längserstreckung der Spanneinheit vorgesehen, so kann die Deckenwandung zwischen diesen Positionen zumindest abschnittsweise an einem in die jeweilige Vertiefung eingelegten Schienenelement ausgebildet sein. Die Schienenelemente können dabei beispielsweise eine Länge von etwa ein bis zwei Meter aufweisen.If the electrical functional elements are only provided at certain positions along the length of the tensioning unit, the ceiling wall between these positions can be formed at least in sections on a rail element inserted into the respective recess. The rail elements can have a length of about one to two meters, for example.
Zusätzlich oder alternativ ist es jedoch auch denkbar, dass die Deckenwandung mit der Mantelfläche zumindest teilweise einstückig ausgebildet ist.Additionally or alternatively, however, it is also conceivable that the top wall is at least partially formed in one piece with the jacket surface.
Dabei kann sich die Deckenwandung in Umfangrichtung des Mantels nur über einen Teil der Öffnungsweite der Vertiefung erstrecken, wodurch die Vertiefung an einem Längsrand oder an beiden Längsrändern eine Hinterschneidung aufweist, in der die wenigstens eine Anschlussleitung für die elektrische Funktionseinheit angeordnet sein kann.The top wall can only extend over part of the opening width of the recess in the circumferential direction of the jacket, whereby the recess has an undercut on one longitudinal edge or on both longitudinal edges in which the at least one connection line for the electrical functional unit can be arranged.
Um die Spanneinheit gegenüber äußeren, beispielsweise von Wind und/oder Wetter ausgeübten, Kräften besonders stabil ausbilden zu können, wird vorgeschlagen, dass die Deckenwandung eine der Anzahl der elektrischen Funktionseinheiten entsprechende Mehrzahl von Durchbrechungen aufweist. Auf diese Weise kann sich der Mantel nämlich auf einem großen Teil der Länge der Spanneinheit über den gesamten Umfang der Spanneinheit erstrecken, so dass er lediglich von den zum Einsetzen der elektrischen Funktionseinheiten erforderlichen Öffnungen durchbrochen wird.In order to be able to make the tensioning unit particularly stable with respect to external forces, for example exerted by wind and / or weather, it is proposed that the top wall have a plurality of openings corresponding to the number of electrical functional units. In this way the jacket can extend over a large part of the length of the tensioning unit over the entire circumference of the tensioning unit, so that it is only penetrated by the openings required for inserting the electrical functional units.
Diese Durchbrechungen bzw. Öffnungen können dabei in Abhängigkeit des jeweiligen Anwendungsfalls kreisrund, oval, rechteckig, quadratisch, polygonal oder gemäß einer beliebigen anderen Form ausgebildet sein.These perforations or openings can be circular, oval, rectangular, square, polygonal or any other shape, depending on the particular application.
Ferner können die Durchbrechungen bzw. Öffnungen bereits bei der Herstellung des Mantels bzw. bei der Herstellung der zur Bildung des Mantels bestimmten Rohrabschnitte eingebracht werden. Grundsätzlich ist es jedoch auch denkbar, die Durchbrechungen bzw. Öffnungen je nach Bedarf erst an der Baustelle in den Mantel einzubringen.Furthermore, the perforations or openings can already be introduced during the production of the jacket or during the production of the pipe sections intended to form the jacket. In principle, however, it is also conceivable to make the perforations or openings in the jacket only at the construction site, as required.
Die wenigstens eine Anschlussleitung kann eine Energiezufuhrleitung, insbesondere eine Leitung zum Zuführen elektrischer Energie zu der wenigstens einen elektrischen Funktionseinheit, und/oder eine Datenleitung zur unidirektionalen oder bidirektionalen Datenverbindung mit der wenigstens einen elektrischen Funktionseinheit sein.The at least one connection line can be an energy supply line, in particular a line for supplying electrical energy to the at least one electrical functional unit, and / or a data line for unidirectional or bidirectional data connection with the at least one electrical functional unit.
Im Falle von Beleuchtungseinheiten kann eine einzige Energiezufuhrleitung ausreichen, wenn die Masseleitung beispielsweise von einer Schiene gebildet wird, die in die Vertiefung eingelegt wird und die Beleuchtungseinheiten trägt. Die Masseleitung kann aber auch als gesonderte Energiezufuhrleitung ausgebildet sein. Soll die Intensität und/oder die Farbe des von den Beleuchtungseinheiten abgestrahlten Lichts variiert werden, so kann ferner eine Datenleitung zur unidirektionalen Kommunikation zwischen einer Steuereinheit und den Beleuchtungseinheiten vorgesehen sein. Sollen von den Beleuchtungseinheiten zudem Statusinformationen abgerufen werden, so kann wenigstens eine weitere Datenleitung zur unidirektionalen Datenverbindung oder eine Datenleitung zur bidirektionalen Datenverbindung vorgesehen sein. Auch für den Fall, dass die elektrischen Funktionseinheiten Sensoreinheiten sind, gelten analoge Überlegungen.In the case of lighting units, a single power supply line can be sufficient if the ground line is formed, for example, by a rail that is inserted into the recess and carries the lighting units. The ground line can, however, also be designed as a separate energy supply line. If the intensity and / or the color of the light emitted by the lighting units is to be varied, a data line for unidirectional communication between a control unit and the lighting units can also be provided. If status information is also to be called up from the lighting units, at least one further data line for the unidirectional data connection or one data line for the bidirectional data connection can be provided. Analogous considerations also apply in the event that the electrical functional units are sensor units.
Um die Tiefe der wenigstens einen Vertiefung im Hinblick auf die Stabilität des Mantels möglichst gering halten zu können, wird in Weiterbildung der Erfindung vorgeschlagen, dass die wenigstens eine Anschlussleitung in Umfangsrichtung gesehen vor und/oder hinter der elektrischen Funktionseinheit verläuft, also in Längsrichtung der Spanneinheit gesehen auf einer Seite oder auf beiden Seiten neben der elektrischen Funktionseinheit. Sofern vorhanden, kann die wenigstens eine Anschlussleitung in einer vorstehend bereits angesprochenen Hinterschneidung angeordnet sein.In order to be able to keep the depth of the at least one recess as small as possible with regard to the stability of the jacket, it is proposed in a further development of the invention that the at least one connection line runs in front of and / or behind the electrical functional unit when viewed in the circumferential direction, i.e. in the longitudinal direction of the tensioning unit seen on one side or on both sides next to the electrical functional unit. If present, the at least one connection line can be arranged in an undercut already mentioned above.
Wie dies an sich bekannt ist, kann der Mantel einen im Wesentlichen kreisförmigen Querschnitt aufweisen.As is known per se, the jacket can have an essentially circular cross section.
Um die elektrischen Funktionseinheiten vor dem Einfluss von Feuchtigkeit, beispielsweise Regen, schützen zu können, kann ferner vorgesehen sein, dass den Begrenzungswandungen der Vertiefungen Dichtungselemente zugeordnet sind, die vorzugsweise dem Übergang von den Begrenzungswandungen zur äußeren Umfangsfläche des Mantels benachbart angeordnet sind.In order to be able to protect the electrical functional units from the influence of moisture, for example rain, provision can also be made for sealing elements to be assigned to the boundary walls of the recesses, which are preferably arranged adjacent to the transition from the boundary walls to the outer circumferential surface of the jacket.
Um nicht mehr ordnungsgemäß arbeitende Funktionseinheiten austauschen zu können, wird vorgeschlagen, dass die wenigstens eine elektrische Funktionseinheit lösbar mit dem Mantel der Spanneinheit verbindbar ist. Hierzu kann einerseits die elektrische Funktionseinheit selbst mit dem Mantel oder einem mit diesem betriebsfest verbundenen Basiselement lösbar verbunden sein. Andererseits ist es auch denkbar, dass ein oder mehrere elektrische Funktionseinheiten betriebsfest an einem Trägerelement angeordnet ist bzw. sind, welches lösbar mit dem Mantel oder einem mit diesem betriebsfest verbundenen Basiselement lösbar verbunden ist.In order to be able to exchange functional units that are no longer working properly, it is proposed that the at least one electrical functional unit be releasably connectable to the jacket of the tensioning unit. For this purpose, on the one hand, the electrical functional unit itself can be detachably connected to the jacket or to a base element that is permanently connected to it. On the other hand, it is also conceivable for one or more electrical functional units to be arranged in an operationally fixed manner on a carrier element which is releasably connected to the jacket or to a base element which is connected to it in an operationally fixed manner.
Die lösbare Verbindung kann beispielsweise durch Verschrauben, Verrasten, Verklemmen, unter Verwendung einer Bajonettverschluss-artigen Verbindung oder dergleichen erfolgen. Dabei können elektrische Kontakte in an sich bekannter Weise realisiert werden. Die betriebsfeste Verbindung kann beispielsweise durch Kleben, Clipsen, Klammern, Schrauben oder dergleichen erfolgen. Sie muss dabei nicht auf der gesamten Länge des Basiselements vorliegen. Vielmehr genügt es sie an wenigstens einer Stelle, vorzugsweise wenigstens zwei Stellen, vorzusehen.The releasable connection can be made, for example, by screwing, latching, clamping, using a bayonet-type connection or the like. Electrical contacts can be implemented in a manner known per se. The operationally stable connection can be made, for example, by gluing, clipping, clamps, screws or the like. It does not have to be present over the entire length of the base element. Rather, it is sufficient to provide them at at least one point, preferably at least two points.
Der Austausch kann beispielsweise mittels eines Roboters erfolgen, welcher sich autonom längs der Spanneinheit fortbewegen kann.The exchange can take place, for example, by means of a robot, which can move autonomously along the clamping unit.
Der Mantel der Spanneinheit kann beispielsweise aus Kunststoff, vorzugsweise hochdichtem Polyethylen (HDPE), oder aus Stahl, vorzugsweise korrosionsgeschütztem Stahl, insbesondere korrosionsgeschütztem Edelstahl, gebildet sein.The jacket of the tensioning unit can be formed, for example, from plastic, preferably high-density polyethylene (HDPE), or from steel, preferably corrosion-protected steel, in particular corrosion-protected stainless steel.
In Weiterbildung der Erfindung kann die innere Begrenzungswandung der wenigstens einen Vertiefung mit dem Mantel einstückig ausgebildet sein. In diesem Fall kann die innere Begrenzungswand der wenigstens einen Vertiefung beim Extrudieren bzw. Strangpressen des Mantels gleich mit ausgebildet werden. Alternativ ist es jedoch auch denkbar, dass die innere Begrenzungswandung der wenigstens einen Vertiefung als gesondertes Element ausgebildet und mit dem Mantel betriebsfest verbunden ist. In diesem Fall kann die innere Begrenzungswandung der wenigstens einen Vertiefung aus dem gleichen Material wie der Mantel oder auch aus einem anderen Material als der Mantel hergestellt sein. Beispielsweise kann der Mantel aus Kunststoff, vorzugsweise hochdichtem Polyethylen (HDPE), und die innere Begrenzungswandung der wenigstens einen Vertiefung aus Stahl, vorzugsweise korrosionsgeschütztem Stahl, insbesondere korrosionsgeschütztem Edelstahl, gebildet sein.In a further development of the invention, the inner delimitation wall of the at least one recess can be designed in one piece with the jacket. In this case, the inner delimitation wall of the at least one depression can be formed at the same time during the extrusion or extrusion of the jacket. Alternatively, however, it is also conceivable that the inner boundary wall the at least one recess is designed as a separate element and is operatively connected to the jacket. In this case, the inner delimitation wall of the at least one recess can be made from the same material as the jacket or from a different material than the jacket. For example, the jacket can be made of plastic, preferably high-density polyethylene (HDPE), and the inner boundary wall of the at least one recess can be made of steel, preferably corrosion-protected steel, in particular corrosion-protected stainless steel.
Wie bereits angedeutet wurde, wird zur Bildung des Mantels üblicherweise von Rohrabschnitten vorbestimmter Länge ausgegangen, die dann durch Schweißen, beispielsweise Spiegelschweißen, miteinander verbunden werden. Analog hierzu können auch die Anschlussleitungen oder/und die in die Vertiefungen einzusetzenden Basiselemente aus Abschnitten vorbestimmter Länge zusammengesetzt sein.As has already been indicated, pipe sections of predetermined length are usually used as the starting point for forming the jacket, which pipe sections are then connected to one another by welding, for example mirror welding. Analogously to this, the connecting lines and / or the base elements to be inserted into the recesses can also be composed of sections of predetermined length.
In Weiterbildung wird vorgeschlagen, dass die Beleuchtungseinheit wenigstens ein Leuchtmittel umfasst. Grundsätzlich ist jedoch auch der Einsatz einer Mehrzahl von Leuchtmitteln denkbar, sei es als Reserve, beispielsweise um den Wartungsaufwand zu reduzieren, oder, um besondere optische Effekte, insbesondere eine Farbänderung des abgestrahlten Lichts, erzielen zu können.In a further development it is proposed that the lighting unit comprises at least one lighting means. In principle, however, the use of a plurality of illuminants is also conceivable, be it as a reserve, for example to reduce maintenance, or to be able to achieve special optical effects, in particular a change in the color of the emitted light.
Im Hinblick auf den Stromverbrauch, aber auch im Hinblick auf die Wärmeabgabe beim Betrieb der Beleuchtungseinheit wird vorgeschlagen, dass das wenigstens eine Leuchtmittel von einer LED gebildet ist. Grundsätzlich ist es jedoch auch denkbar, andere Arten von Leuchtmitteln einzusetzen, beispielsweise Halogenlampen, Leuchtstoffelemente oder dergleichen.With regard to the power consumption, but also with regard to the heat dissipation during the operation of the lighting unit, it is proposed that the at least one lighting means is formed by an LED. In principle, however, it is also conceivable to use other types of lighting means, for example halogen lamps, fluorescent elements or the like.
Um die Sichtbarkeit der Beleuchtungseinheit unabhängig vom Betrachtungswinkel verbessern zu können, kann vorgesehen sein, dass die wenigstens eine Beleuchtungseinheit eine integrierte Optik, vorzugsweise Streuoptik, aufweist.In order to be able to improve the visibility of the lighting unit independently of the viewing angle, it can be provided that the at least a lighting unit has integrated optics, preferably scatter optics.
Darüber hinaus kann die Beleuchtungseinheit eine lokale Steuereinheit umfassen, welche Ansteuerung des wenigstens einen Leuchtmittels dient, beispielsweise in Abhängigkeit von den Vorgaben einer zentralen Steuereinheit zur Steuerung der Gesamtheit aller Beleuchtungseinheiten der Spanneinheit oder wenigstens einer Mehrzahl von Spanneinheiten, vorzugsweise aller Spanneinheiten, des Bauwerks.In addition, the lighting unit can include a local control unit which controls the at least one lighting means, for example depending on the specifications of a central control unit to control the entirety of all lighting units of the tensioning unit or at least a plurality of tensioning units, preferably all tensioning units, of the structure.
Der Vollständigkeit halber sei noch darauf hingewiesen, dass wenigstens ein Teil der Spannelemente in an sich bekannter Weise als Spannlitzen ausgebildet sein kann. Beispielsweise können die Spannlitzen aus sieben Drähten gebildet sein und/oder einen Durchmesser von etwa 15,7 mm aufweisen. Alternativ ist es jedoch auch denkbar, dass die Spannelemente von nicht verseilten, zueinander im Wesentlichen parallel verlaufenden Drähten gebildet sind, wobei dieses Drähte vorzugsweise einen Durchmesser von etwa 7,0 mm aufweisen.For the sake of completeness, it should also be pointed out that at least some of the tensioning elements can be designed as tensioning strands in a manner known per se. For example, the tensioning strands can be formed from seven wires and / or have a diameter of approximately 15.7 mm. Alternatively, however, it is also conceivable that the tensioning elements are formed by non-stranded wires that run essentially parallel to one another, these wires preferably having a diameter of approximately 7.0 mm.
Nachzutragen ist ferner, dass an der äußeren Oberfläche des Mantels wenigstens ein Wasserabweisungselement vorgesehen sein kann, welches dazu dient, Wasser, insbesondere Regenwasser, das sich auf der äußeren Oberfläche des Mantels angesammelt hat und dort aufgrund von Wind und Wetter als Rinnsal längs der Spanneinheit fließt, wieder von der Oberfläche des Mantels zu lösen und in die umgebende Luft abzugeben, wo es durch Wind und Wetter von der Spanneinheit fortgetragen wird. Derartige Wasserabweisungselemente können vorzugsweise als von der äußeren Oberfläche des Mantels abstehende Stege ausgebildet sein, welche beispielsweise die Form einer sich in Längsrichtung der Spanneinheit um den Mantel windenden Wendel oder die Form eines den Mantel umgebenden Rings aufweisen können. Der Verlauf des Übergangs von der äußeren Oberfläche des Mantels zum Steg und/oder das freie Ende des Stegs kann bzw. können dabei im Hinblick auf eine möglichst effektive Ableitung des Wassers optimiert ausgebildet sein.It should also be added that at least one water-repellent element can be provided on the outer surface of the jacket, which serves to water, in particular rainwater, that has accumulated on the outer surface of the jacket and flows there as a trickle along the tensioning unit due to wind and weather to be released again from the surface of the jacket and released into the surrounding air, where it is carried away by the clamping unit by wind and weather. Such water-repellent elements can preferably be designed as webs protruding from the outer surface of the jacket, which for example can have the shape of a helix winding around the jacket in the longitudinal direction of the tensioning unit or the shape of a ring surrounding the jacket. The course of the transition from the outer surface of the jacket to the web and / or the free end of the web can or can be in the With regard to the most effective possible drainage of the water, be designed to be optimized.
Nachzutragen ist schließlich auch noch, dass der Innenraum des Mantels im betriebsbereiten Zustand der Spanneinheit zumindest teilweise, vorzugsweise vollständig, mit einem Füllmaterial, vorzugsweise einem Korrosionsschutzmaterial, beispielsweise Wachs, Mörtel oder dergleichen, gefüllt sein kann.Finally, it should also be added that the interior of the jacket can be filled at least partially, preferably completely, with a filler material, preferably a corrosion protection material, for example wax, mortar or the like, when the clamping unit is ready for operation.
Gemäß einem weiteren Aspekt wird die erfindungsgemäße Aufgabe durch eine Spanneinheit der eingangs genannten Art gelöst, bei welcher auf der äußeren Oberfläche des Mantels wenigstens ein Wasserabweisungselement angeordnet ist, welches wenigstens eine Ausnehmung aufweist, in der wenigstens eine elektrische Funktionseinheit, beispielsweise wenigstens eine Beleuchtungseinheit, aufgenommen ist und welche ferner wenigstens eine Anschlussleitung für die wenigstens eine elektrische Funktionseinheit umfasst.According to a further aspect, the object of the invention is achieved by a tensioning unit of the type mentioned at the outset, in which at least one water-repellent element is arranged on the outer surface of the jacket, which has at least one recess in which at least one electrical functional unit, for example at least one lighting unit, is received and which further comprises at least one connection line for the at least one electrical functional unit.
Diese alternative Lösung erzielt die gleichen technischen Vorteile, wie die vorstehend diskutierte Lösung. Diesbezüglich kann daher auf die vorstehende Diskussion verwiesen werden. Sie ist mit dieser durch das beiden Lösungen gemeinsame, aus dem Stand der Technik nicht bekannte, technische Konzept verbunden, die wenigstens eine elektrische Funktionseinheit in den Mantel der Spanneinheit zu integrieren.This alternative solution achieves the same technical advantages as the solution discussed above. In this regard, reference can therefore be made to the discussion above. It is connected to this technical concept, which is common to both solutions and is not known from the prior art, of integrating the at least one electrical functional unit into the jacket of the tensioning unit.
In Weiterbildung der alternativen Lösung wird vorgeschlagen, dass die wenigstens eine Anschlussleitung in einem Kanal aufgenommen ist, welcher in dem wenigstens einen Wasserabweisungselement ausgebildet ist. Alternativ ist es jedoch auch denkbar, dass der Mantel an wenigstens einer Umfangsposition eine in den Innenraum hinein ragende Vertiefung aufweist, in der die wenigstens eine Anschlussleitung aufgenommen ist.In a further development of the alternative solution, it is proposed that the at least one connection line is received in a channel which is formed in the at least one water-repellent element. Alternatively, however, it is also conceivable that the jacket has a recess protruding into the interior space at at least one circumferential position, in which the at least one connection line is received.
Abschließend sei darauf hingewiesen, dass die Spannelemente bei der Spanneinheit gemäß dieses weiteren Aspekts nicht nur von zu Litzen verseilten Drähten oder nicht verseilten, zueinander im Wesentlichen parallel verlaufenden Drähten gebildet sein können, sondern auch von vollständig verseilten Drähten, d.h. Drähten, die zu einem einzigen Seil verseilt worden sind.Finally, it should be pointed out that the tensioning elements in the tensioning unit according to this further aspect can be formed not only from wires stranded to form strands or non-stranded wires that run essentially parallel to one another, but also from completely stranded wires, that is, wires that are combined into a single Rope have been stranded.

In die Vertiefungen 108 sind Schienenelemente 110 eingelegt, welche an vorbestimmten Positionen mit Beleuchtungseinheiten 112 bestückt sind. Ferner weisen die Schienenelemente 110 Anschlussleitungen für die Beleuchtungseinheiten 112 auf, nämlich Stromversorgungsleitungen 114a und Datenleitungen 114b. Die Stromversorgungsleitungen 114a versorgen Beleuchtungselemente 116 der Beleuchtungseinheiten 112, die vorzugsweise von LEDs gebildet sind, mit der zu ihrem Betrieb erforderlichen Energie. Über die Datenleitungen 114b, die mit einer lokalen Steuereinheit 118 der jeweiligen Beleuchtungseinheit 112 verbunden sind, kann gesteuert werden, wann die Beleuchtungselemente 116 in welcher Intensität und/oder Farbe leuchten. Um sicherstellen zu können, dass das von den Beleuchtungseinheiten 112 abgestrahlte Licht in einem großen Raumwinkel zu sehen ist, verfügen die Beleuchtungseinheiten 112 ferner über eine Streuoptik 120. Um das Eindringen von Feuchtigkeit in die Vertiefungen 110 verhindern zu können, sind am Übergang von der äußeren Umfangsfläche 102a des Mantels 102 zur Vertiefung 108 Dichtungen 122 angeordnet.
Wie in
Somit erhöht sich bei an sich gleich bleibender Wandstärke d des Mantels 102 der Flächeninhalt der Querschnittsfläche 102a des Mantels 102 und damit der gesamten Spanneinheit 100 trotz des Vorsehens der Vertiefungen 108 zur Aufnahme der Beleuchtungseinheiten 112 nur geringfügig, nämlich lediglich um die Querschnittsfläche der zur Ausbildung der Vertiefungen 108 erforderlichen Einbuchtungen des Mantels 102.Thus, with the wall thickness d of the

Um nicht mehr ordnungsgemäß arbeitende Beleuchtungseinheiten 112 austauschen zu können, können die Beleuchtungseinheiten 112 gemäß einer ersten Ausführungsvariante lösbar mit den Schienenelementen 110 verbunden sein. In diesem Fall können die Schienenelemente 110 unlösbar mit dem Mantel 102 der Spanneinheit 100 verbunden sein. Gemäß einer zweiten Ausführungsvariante ist es jedoch auch denkbar, dass die Beleuchtungseinheiten 112 unlösbar mit den Schienenelementen 110 verbunden sind, dass aber die Schienenelemente 110 lösbar mit dem Mantel 102 der Spanneinheit 100 verbunden sind.In order to be able to replace
Die lösbare Verbindung kann beispielsweise durch Verschrauben, Verrasten, Verklemmen, unter Verwendung einer Bajonettverschluss-artigen Verbindung oder dergleichen erfolgen. Dabei können elektrische Kontakte in an sich bekannter Weise realisiert werden. Die unlösbare Verbindung kann beispielsweise durch Kleben, Clipsen, Klammern, Schrauben oder dergleichen erfolgen. Sie muss dabei nicht auf der gesamten Länge des Schienenelements 110 vorliegen.The releasable connection can be made, for example, by screwing, latching, clamping, using a bayonet-type connection or the like. Electrical contacts can be implemented in a manner known per se. The permanent connection can be made, for example, by gluing, clipping, clamps, screws or the like. It does not have to be present over the entire length of the

Die Spanneinheit 200 unterscheidet sich von der Spanneinheit 100 hauptsächlich durch die Ausbildung der Vertiefungen 208. Und zwar verfügen die Vertiefungen 208 über Hinterschneidungen 208b und 208c, in denen die Stromversorgungsleitungen 214a und Datenleitungen 214b angeordnet sind. Auf diese Weise können die Stromversorgungsleitungen 214a und die Datenleitungen 214b in Umfangsrichtung U vor bzw. hinter der Beleuchtungseinheit 212 verlaufen. Dies ermöglicht es, die Vertiefungen 208 mit einer geringeren radialen Tiefe auszubilden, was sich vorteilhaft auf die Stabilität des Mantels 202 auswirkt. Nach radial außen sind die Hinterschneidungen 208b und 208c von einstückig mit dem Mantel 202 ausgebildeten Wandungsabschnitten 202b begrenzt.The
