Description

Gittermaststruktur sowie Verfahren Standfestigkeitserhöhung an eine Gittermaststruktur Lattice mast structure and method Stability increase to a lattice mast structure
Die Erfindung betrifft eine Gittermaststruktur umfassend als Stahlprofile ausgebildete Stützen und sich zwischen den Stützen erstreckenden Diagonalstreben oder Querstreben oder Diagonalstreben und Querstreben. The invention relates to a lattice mast structure comprising supports designed as steel profiles and extending between the supports diagonal struts or cross struts or diagonal struts and cross struts.
Die Erfindung betrifft weiterhin ein Verfahren zur Standfestigkeitserhöhung an eine solche Gittermaststruktur als nachträgliche Ertüchtigung. The invention further relates to a method for increasing the stability of such a lattice mast structure as a subsequent upgrade.
Gittermaststrukturen der vorbezeichneten Art sind offene Stahlfachwerkbauwerke mit Winkelprofilen oder Rundprofilen an Brücken, in Form von Pylonen oder Stromleitungsmasten. Derartige Gittermaststrukturen besitzen den Vorzug, dass sie besonders leichgewichtig und leicht aufzubauen sind. Insbesondere wenn die Gittermaststruktur aus Winkelprofilen besteht, sind die einzelnen Profilstreben verhältnismäßig leicht aneinander anschließbar, beispielsweise durch Nieten, Schweißen oder Verschrauben . Lattice mast structures of the aforementioned type are open steel truss structures with angle profiles or round profiles on bridges, in the form of pylons or electricity pylons. Such lattice mast structures have the advantage that they are particularly lightweight and easy to build. In particular, when the lattice mast structure consists of angle profiles, the individual profile struts are relatively easy to connect to each other, for example by riveting, welding or screwing.
Gittermaststrukturen finden überwiegend als Gittermasten zur Aufnahme elektrischer Überlandleitungen Anwendung. Gittermasten sind üblicherweise aus einer Reihe von übereinander angeordneten Strukturelementen aufgebaut, wobei jede Stufe eine Fachwerkstruktur bildet, die drei oder mehr trapezförmige Fachwerkfelder aufweist, die jeweils aus miteinander verstrebten Stützen bestehen. Die Stützen sind als Winkelprofile ausgebildet, die diese verbindenden Streben in Form von Querstreben oder Diagonalstreben können ebenfalls teilweise als Winkelprofile, teilweise auch als Laschenprofile ausgebildet sein. Die Gestaltung solcher Fachwerkstrukturen ordnet sich in der Regel den Anforderungen an die Traglast und an die auf das Bauwerk einwirkende Windlast unter. Weiterhin sind für die Auslegung die Kräfte aus Eigengewicht, Abspannung, Eis und Temperatur zu berücksichtigen. Lattice mast structures are mainly used as lattice towers for receiving electrical transmission lines. Lattice masts are usually constructed of a series of superimposed structural elements, each step forming a truss structure having three or more trapezoidal truss panels, each consisting of struts braced together. The supports are designed as angle profiles, these connecting struts in the form of cross struts or diagonal struts can also be partially formed as angle profiles, in part, as tab profiles. The design of such framework structures is usually subordinated to the requirements of the load and the wind load acting on the structure. Furthermore, the forces of dead weight, bracing, ice and temperature are to be considered for the interpretation.
Die Dimensionierung der die Fachwerkstruktur bildenden Bauelemente ist einerseits von der freien Knicklänge der einzelnen Elemente, der in diesen herrschenden Zuspannung oder Druckspannung und andererseits von dem Zusammenwirken von Längskräften und seifigen Kräften abhängig, die beispielsweise durch Windlasten in das Bauwerk eingetragen werden . Zur Stabilisierung von Gitterbauwerken oderThe dimensioning of the truss structure forming components on the one hand depends on the free buckling length of the individual elements in this prevailing Zuspannung or compressive stress and on the other hand by the interaction of longitudinal forces and soapy forces, which are registered for example by wind loads in the building. For the stabilization of lattice structures or
Fachwerkstrukturen der zuvor beschriebenen Art sind zahlreiche Verstrebungssysteme bekannt, die hinsichtlich der Anordnung der Fachwerkstreben und im Hinblick auf das Gesamtgewicht der Gitterstruktur optimiert sind. Ein solches System ist beispielsweise in der GB 675,859 A beschrieben. Truss structures of the type described above are known numerous strut systems, which are optimized in terms of the arrangement of the truss struts and in terms of the total weight of the lattice structure. Such a system is described for example in GB 675,859 A.
Bei der Erstellung von neuen Gittermasten beziehungsweise Gittermaststrukturen ist in der Regel die optimale Auslegung der Struktur für eine zu erwartende Windlast und Traglast in Bezug auf eine Gewichtsoptimierung verhältnismäßig unproblematisch . In the creation of new lattice masts or lattice mast structures, the optimal design of the structure for an expected wind load and load in relation to a weight optimization is usually relatively unproblematic.
Beispielsweise bei bestehenden Gittermasten für elektrische Überlandleitungen ist es von Zeit zu Zeit gegebenenfalls erforderlich, Teile der Konstruktion auszubessern und/oder zu erneuern. Dies erfordert unter Umständen neue Standfestigkeitsnachweise. Bestehende Anlagen erfüllen erhöhte Standfestigkeitsanforderungen unter Umständen nicht, insbesondere auch wegen erhöhter Lastanforderungen oder wegen einer über eine längere Standzeit zu erwartende Strukturschwächung . For example, in existing lattice towers for electrical power lines, it may be necessary from time to time to repair and / or renew parts of the construction. This may require new proof of strength. Existing systems may not meet increased stability requirements, in particular because of increased load requirements or because of expected over a longer life structural weakening.
Manchmal müssen Gittermasten an ihren Mastauslegern zusätzliche Leitungen aufnehmen, weil beispielsweise in einem elektrischen Stromnetz eine größere elektrische Leistung bereitgestellt werden muss. Sometimes lattice towers have to accommodate additional lines on their mast booms, because, for example, in a power grid, a greater electrical power must be provided.
In solchen Fällen ist eine Ertüchtigung der bestehenden Gittermasten erforderlich, insbesondere, wenn die freie Knicklänge der Stahlprofile nicht für eine erhöhte Traglast ausgelegt ist oder der Querschnitt als solcher nicht genügend Tragfähigkeit aufweist. Der Erfindung liegt daher die Aufgabe zugrunde, eine ertüchtige Gittermaststruktur sowie ein Verfahren zur Ertüchtigung herkömmlicher Gittermaststrukturen bereitzustellen. Die Aufgabe wird gelöst mit den Merkmalen des Anspruchs 1 sowie mit den Merkmalen des nebengeordneten Anspruchs 8. Bevorzugte Varianten der Erfindung ergeben sich jeweils aus den Unteransprüchen. Unter einer Gittermaststruktur im Sinne der vorliegenden Erfindung ist eine offene Fachwerkstruktur zu verstehen, deren Streben nicht mit Ausfachungen versehen sind. In such cases, a retrofitting of the existing lattice towers is required, especially if the free buckling length of the steel profiles is not designed for an increased load or the cross-section as such does not have sufficient capacity. The invention is therefore based on the object to provide an ertüchtige lattice boom structure and a method for upgrading conventional lattice structures. The object is achieved with the features of claim 1 and with the features of the independent claim 8. Preferred variants of the invention will become apparent from the dependent claims. Under a lattice mast structure in the context of the present invention is an open framework structure to understand the struts are not provided with infills.
Als Gittermaststruktur kommen beispielsweise Gittermasten zur Aufnahme elektrischer Überlandleitungen, Pylone, Brückenpfeiler oder dergleichen in Betracht, die in Erstreckungsrichtung von als Stützen ausgebildeten Stahlprofilen hinsichtlich der gewünschten Knickstabilität zu ertüchtigen sind. Nach einem Gesichtspunkt der Erfindung ist eine Gittermaststruktur umfassend Stützen, die als Stahlprofile ausgebildet sind und sich zwischen den Stützen erstreckende Diagonalstreben oder Querstreben oder Diagonalstreben und Querstreben vorgesehen, wobei die Gittermaststruktur wenigstens einen Verstärkungsstab umfasst, wobei der Verstärkungsstab sich in Längsrichtung in einer Stütze oder einer Querstrebe oder einer Diagonalstrebe erstreckt, der Verstärkungsstab im Verlauf der Stütze oder der Querstrebe (6) oder der Diagonalstrebe folgt, der Verstärkungsstab an wenigstens zwei voneinander abliegenden Stellen mit der Stütze oder der Querstrebe (6) oder der Diagonalstrebe verbunden ist, so dass der Verstärkungsstab hinsichtlich des Kraftflusses durch die Stütze oder die Querstrebe oder die Diagonalstrebe mit dieser einen Strukturverbund bildet und der Verstärkungsstab als wenigstens zweiteiliges Bauteil ausgebildet ist, dass als vorzugsweise zweiteiliger Strukturverbund aus einem überwiegend Zugkräfte übertragenden Element und einem überwiegend Druckkräfte übertragenden Element ausgebildet ist. As a lattice mast structure are, for example, lattice towers for receiving electrical power lines, pylons, bridge piers or the like into consideration, which are to be trained in the extension direction of designed as columns steel profiles in terms of the desired buckling stability. According to one aspect of the invention, a lattice mast structure comprising supports formed as steel profiles and extending between the struts diagonal struts or cross struts or diagonal struts and cross struts, said lattice mast structure comprises at least one reinforcing rod, wherein the reinforcing rod in the longitudinal direction in a support or a Cross bar or a diagonal strut, the reinforcing rod in the course of the support or the crossbar (6) or the diagonal strut follows, the reinforcing rod is connected at at least two spaced locations with the support or the crossbar (6) or the diagonal strut, so that the reinforcing rod with respect to the power flow through the support or the cross member or the diagonal strut forms a structural composite with this and the reinforcing rod is formed as at least two-part component, that as preferably two-part structure composite of e is formed inem predominantly tensile forces transmitting element and a predominantly compressive forces transmitting element.
Unter einem Stahlprofil im Sinne der vorliegenden Erfindung kann ein Rundprofil oder auch ein Winkelprofil zu verstehen sein. A steel profile in the sense of the present invention may be understood to mean a round profile or also an angle profile.
Unter einem Winkelprofil im Sinne der vorliegenden Erfindung ist beispielsweise ein T-Profil, L-Profil, I-Profil, Z- Profil, U-Profil, C-Profil oder dergleichen zu verstehen. For the purposes of the present invention, an angle profile means, for example, a T-profile, L-profile, I-profile, Z-profile, U-profile, C-profile or the like.
Die Gittermaststruktur im Sinne der vorliegenden Erfindung kann beispielsweise als Stahlfachwerkstruktur mit drei oder vier Stützen insbesondere Stützen, ausgebildet sein, die in Richtung einer Mastspitze konvergieren können. Dabei können jeweils zwei Stützen zusammen mit Querstreben trapezförmige Felder einer Maststufe bilden. Mehre Maststufen können sich der Höhe nach von einer Basis des Gittermastes zu dessen Mastspitze erstrecken. Der Gittermast kann beispielsweise symmetrisch zu den Stützen angeordnete Mastausleger aufweisen, die ihrerseits eine entsprechendeThe lattice mast structure in the sense of the present invention can be designed, for example, as a steel truss structure with three or four supports, in particular supports, which can converge in the direction of a mast top. It can each two columns together with cross struts trapezoidal fields form a mast level. Several mast steps may extend in height from a base of the lattice mast to its mast top. The lattice mast may have, for example, fins arranged symmetrically to the supports, which in turn a corresponding

Vorzugsweise ist darunter ein Element zu verstehen, dass mehr als doppelt so hohe Zugkräfte als Druckkräfte übertragen kann. Truss structure and taper from a base to its distal end. Under a predominantly tensile forces transmitting element in the context of the present invention is an element to understand that can transmit greater tensile forces than compressive forces. Preferably, this is understood to mean an element that can transmit more than twice as high tensile forces as compressive forces.

Under a compressive force transmitting element according to the present invention is an element to understand that can transmit more compressive forces than tensile forces, preferably more than twice as high compressive forces as tensile forces.

The compressive force transmitting element is preferably selected from a group comprising concrete, polymer concrete, mineral potting compounds and thermoplastic non-foamed and thermoplastic and foamed potting compounds.
Das Zugkräfte übertragende Element kann beispielsweise in Form eines oder mehrerer Seile oder in Form eines Schlauches ausgebildet sein. Der Grundgedanke der Erfindung ist darin zu sehen, dass mittels eines oder mehrerer Verstärkungsstäben an wenigstens einer, bevorzugt an mehreren Stützen durch einen Strukturverbund des Verstärkungsstabs mit der Stütze die freie Knicklänge der betreffenden Stütze und damit auch deren Traglast in Längsrichtung erhöht wird. The tensile forces transmitting element may be formed for example in the form of one or more ropes or in the form of a tube. The basic idea of the invention can be seen in that by means of one or more reinforcing rods on at least one, preferably on several supports by a structural composite of the reinforcing rod with the support the free buckling length of the respective support and thus also their load in the longitudinal direction is increased.
Je Stütze kann beispielsweise ein sich jeweils über die volle Länge der Stütze erstreckender Verstärkungsstab vorgesehen sein, der an mehreren Stellen mit Abstand zueinander mit der Stütze fest verbunden ist. Alternativ können über die Länge einer Stütze abschnittsweise mehrere Verstärkungsstäbe mit dieser befestigt sein. Die Ausbildung des Verstärkungsstabs als wenigstens zweiteiliges Verbundbauteil hat den Vorzug, dass hierdurch die Montage stark vereinfacht wird. Das Zugkräfte übertragende Element kann als biegbares Element ausgebildet sein, welches einfach verlegbar ist. Das Druckkräfte übertragende Element kann beispielsweise aus einer ausgehärteten Vergussmasse bestehen, wodurch ebenfalls die Handhabbarkeit des Verstärkungsstabs zwecks Montage stark vereinfacht wird. Bei einer vorzugsweisen Ausgestaltung der zuvor beschriebenen Gittermaststruktur ist vorgesehen, dass der Verstärkungsstab ein Zugelement aus Stahl und einen Stahlkörper aus einer ausgehärteten Vergussmasse umfasst. For each support may be provided, for example, each extending over the full length of the support reinforcing rod, which is firmly connected at several points with distance from each other with the support. Alternatively, a plurality of reinforcing rods may be attached in sections over the length of a support. The formation of the reinforcing rod as at least two-part composite component has the advantage that this assembly is greatly simplified. The tensile forces transmitting element may be formed as a bendable element, which is easy to install. The compressive force-transmitting element may for example consist of a cured potting compound, whereby also the handling of the reinforcing rod for the purpose of assembly is greatly simplified. In a preferred embodiment of the lattice mast structure described above, it is provided that the reinforcing rod comprises a tension member made of steel and a steel body made of a hardened potting compound.

Alternativ ist auch eine parallele Anordnung eines oder mehrerer Stahlseile und eines Körpers aus einer ausgehärteten Vergussmasse möglich. Diese können abschnittsweise miteinander verbunden sein. Die aushärtbare Vergussmasse kann in diesem Falle beispielsweise in einem flexiblen Textilschlauch als Verlegehilfe und verlorene Schalung für die Vergussmasse eingeschlossen sein. Bei einer alternativen Variante der Gittermaststruktur kann vorgesehen sein, dass der Verstärkungsstab einen Mantel aus einem zugfesten Stahlgewebe oder einem stahlarmierten Textilgewebe oder einem Stahlgeflecht und eine Seele aus einer ausgehärteten Vergussmasse aufweist. For example, the reinforcing rod may comprise one or more steel cables embedded in a shell of a cured potting compound. Alternatively, a parallel arrangement of one or more steel cables and a body of a cured potting compound is possible. These can be connected to each other in sections. The curable potting compound can in this case be included for example in a flexible textile hose as a laying aid and lost formwork for the potting compound. In an alternative variant of the lattice mast structure can be provided that the reinforcing rod has a sheath of a tensile steel fabric or a steel-reinforced textile fabric or a steel mesh and a soul of a cured potting compound.

Dieses kann beispielsweise von einer Mastspitze der Gittermaststruktur zu einem Mastfuß oder zu einem Mastfundament oder einem Mastsockel verlegt sein und zwischen den Befestigungspunkten vorgespannt sein. Durch anschließendes Vergießen oder Verpressen des Zugkräfte übertragenden Elements mit der aushärtbaren Vergussmasse kann die Zugspannung eingefroren worden sein. Preferably, the reinforcing bar is in each case connected to the corner support in the region of nodal points of the lattice mast structure. In a particularly advantageous variant of the lattice mast structure according to the invention can be provided that the tensile forces transmitting element is biased. This can for example be laid from a mast top of the lattice mast structure to a mast base or to a mast foundation or a mast base and be biased between the attachment points. By subsequent casting or pressing the tensile forces transmitting element with the curable potting compound, the tensile stress may have been frozen.

Die Erfindung wird nachstehend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels erläutert. The invention will be explained below with reference to an embodiment shown in the drawings.
Es zeigen: Show it:
Figur 1: eine schematische Darstellung eines Gittermastes als Überlandleitungsmast zur Aufnahme von elektrischen Überlandleitungen, Figur 2: einen Querschnitt durch eine Stütze des in Figur 1 dargestellten Gittermastes mit einemFIG. 1 shows a schematic representation of a lattice mast as a transmission line mast for receiving electrical transmission lines; Figure 2: a cross section through a support of the lattice mast shown in Figure 1 with a
Verstärkungsstab gemäß der Erfindung. Der Gittermast 1 als Gittermaststruktur im Sinne der vorliegenden Erfindung ist in Figur 1 als herkömmliche, offene Stahlfachwerkkonstruktion mit vier Stützen 2 ausgebildet, die im vorliegenden Fall als offene Winkelprofile 3 mit zwei gleichlangen Schenkeln 4 und einem Winkelscheitel 10 ausgebildet sind. Reinforcing bar according to the invention. The lattice mast 1 as a lattice mast structure according to the present invention is formed in Figure 1 as a conventional, open steel framework construction with four supports 2, which are formed in the present case as open angle sections 3 with two equal legs 4 and an angle peak 10.
Der Gittermast 1 wird hier beispielsweise als eine Fachwerkstruktur mit Winkelprofilen, insbesondere als offenes Stahlfachwerkbauwerk beschrieben. The lattice mast 1 is described here, for example, as a truss structure with angle profiles, in particular as an open steel truss structure.
Wie eingangs bereits erwähnt wurde, ist die Erfindung so zu verstehen, dass als Fachwerkstruktur Gittermaststrukturen auch Brückstrukturen, Pylone oder ähnliche Bauwerke vorgesehen sein können. As already mentioned, the invention is to be understood such that lattice mast structures and bridge structures, pylons or similar structures can be provided as truss structure.
Wie der Figur 1 zu entnehmen ist, nimmt der Gittermast im Bereich seiner Aufstellung eine verhältnismäßig große Aufsteilfläche in Anspruch, die vier Stützen 2 des Gittermastes 1 konvergieren in Richtung auf eine Mastspitze 5. Jeweils zwei Stützen 2 bilden zusammen mit Querstreben 6 trapezförmige Felder eine Maststufe. Jede Maststufe wird insgesamt durch vier trapezförmige Felder beschrieben, mehrere Maststufen erstrecken sich der Höhe nach von der Basis des Gittermastes 1 zu dessen Mastspitze 5. Die einzelnen Felder der Stufen des Gittermastes sind als Fachwerkstrukturen mit Diagonalstreben 9 ausgebildet, die je nach Höhe der Querbelastung des Gittermastes als Druckstäbe oder Zugstäbe wirken. Die sich in Richtung auf die Mastspitze 5 verschlankende Form des Gittermastes 1 ist der erwartenden Biegebeanspruchung des Gittermastes 1 aufgrund von Windlast und aufgrund von Leitungen 7 geschuldet. Die Leitungen 7 sind in bekannter Art und Weise an Mastauslegern 8 aufgehängt. Die Geometrie der Mastausleger ist dem erwartenden Biegemomentverlauf bedingt durch die Gewichtskraft der Leitungen 7 angepasst. Es wird nun Bezug genommen auf Figur 2, die eine Schnittansicht einer Stütze 2 des Gittermastes 1 als Winkelprofil 3 im Sinne der vorliegenden Anmeldung zeigt. Der Schnitt ist als Querschnitt auf Höhe eines Knotenpunktes der Fachwerkstruktur des Gittermastes 1 dargestellt. Im Bereich des Knotenpunktes sind zwei Querstreben 6 zu benachbarten Stützen 2 an den Schenkeln 4 des Winkelprofils 3 befestigt. Der Winkelscheitel 10 des Winkelprofils 3 der Stütze 2 zeigt auswärts des von den Stützen 2 eingeschlossenen Mastquerschnitts. Mit 11 sind Steigeisen an den Stützen 2 bezeichnet. As can be seen from FIG. 1, the lattice mast in the region of its installation occupies a relatively large spreading surface, the four supports 2 of the lattice mast 1 converge in the direction of a mast top 5. In each case two supports 2 together with transverse struts 6 form a mast step , Each mast step is described in total by four trapezoidal fields, several mast steps extend in height from the base of the lattice mast 1 to the mast top 5. The individual fields of the steps of the lattice mast are formed as truss structures with diagonal struts 9, depending on the amount of transverse load of the Lattice mast as pressure bars or tension bars act. The leaning towards the mast top 5 form of the lattice mast 1 is due to the expected bending stress of the lattice mast 1 due to wind load and due to lines 7. The lines 7 are suspended in a known manner to mast brackets 8. The geometry of the mast boom is adapted to the expected bending moment course due to the weight of the lines 7. Reference is now made to Figure 2, which shows a sectional view of a support 2 of the lattice mast 1 as an angle section 3 in the sense of the present application. The section is shown as a cross section at the height of a node of the truss structure of the lattice mast 1. In the region of the junction, two transverse struts 6 are fastened to adjacent supports 2 on the legs 4 of the angle profile 3. The angle vertex 10 of the angle section 3 of the support 2 points outwards of the mast cross-section enclosed by the supports 2. With 11 crampons are referred to the supports 2.
Wie dies aus der Schnittansicht erkennbar ist, sind auf den Schenkeln 4 des Winkelprofils 3 außen an den Winkelscheitel 10 angrenzend zwei Verstärkungsstäbe 12 befestigt, die erfindungsgemäß als zweiteiliges Verbundbauteil ausgebildet sind. Die Verstärkungsstäbe 12 umfassen einen Stahlgeflechtmantel, der als durchgehender Schlauch an der betreffenden Stütze 2 von dem nicht näher bezeichneten Fundament des Gittermastes 1 bis zur Mastspitze 5 verlegt ist, und der jeweils im Bereich der Knotenpunkte der Fachwerkstruktur, das heißt im Bereich der an die Stütze 2 angeschlossen Querstreben 6 mit der Stütze 2 verbunden ist. Die Verbindung kann beispielsweise mittels nicht dargestellter Schellen vorgesehen sein, die mit den Stützen 2 beziehungsweise mit den Winkelprofilen 3 der Stützen 2 verschweißt sind. As can be seen from the sectional view, two reinforcing rods 12 are attached to the legs 4 of the angle profile 3 outside the angle apex 10 adjacent, which are formed according to the invention as a two-part composite component. The reinforcing rods 12 comprise a steel braided sheath, which is laid as a continuous hose on the respective support 2 of the unspecified foundation of the lattice mast 1 to the mast top 5, and in each case in the region of the nodes of the truss structure, that is in the region of the support 2 connected crossbars 6 is connected to the support 2. The connection can be provided for example by means not shown clamps, with the supports 2 or welded to the angle profiles 3 of the supports 2.
Die Verstärkungsstäbe 12 umfassen weiterhin einen Kern beziehungsweise eine Seele aus einer ausgehärtenen Vergussmasse, die von unten beginnend in den Stahlgewebeschlauch gepresst wurde. Die fertig gestellten und ausgehärteten Verstärkungsstäbe 12 bilden eine Strukturversteifung der Winkelprofile 3 und somit eine Erhöhung deren Traglast und deren freier Knicklänge. The reinforcing bars 12 further comprise a core of a hardened potting compound that has been pressed from below into the steel fabric tube. The finished and cured reinforcing rods 12 form a structural reinforcement of the angle sections 3 and thus an increase in their load and their free buckling length.
