Abstract
Description
Stand der TechnikState of the art
Soweit rohrförmige Konstruktionen nach oben
in aufgelöste übergeführt werden,
ist vor allem eine Aufteilung des Rohrquerschnitts in Segmente und
gegebenenfalls deren weitere Umformung bzw. Ergänzung naheliegend, wie etwa
im Patent
Neue LösungNew solution
Zweckmäßige Ausführungen ergeben sich mit den in den Ansprüchen beschriebenen Ausführungsweisen.Appropriate designs result with the in the claims described embodiments.
Vorteilebenefits
Die Ausprägung gemäß Anspruch 1 nutzt die Tatsache,
dass es zur Kraftübertragung,
insbesondere von hauptsächlich
nicht aus Gewichtskräften
herrührenden
Lasten, nicht erforderlich ist, dass sich der Turm axial oberhalb
des Pfahls befindet. Eine günstige
Verbindung zwischen Fachwerk (oben) und Pfahl (unten) kann anspruchsgemäß dadurch
erreicht werden, dass die obere Verlängerung eines Pfahls eine Stütze (
Diese Lösung bietet sich unter anderem an, wenn die Steifigkeit der Struktur bzw. der Materialbedarf durch zusätzliche Stützen in genügendem Abstand verbessert werden soll, während der unter bodenmechanischen Gesichtspunkten dimensionierte Pfahldurchmesser und der zur Übertragung von Drehmomenten um eine vertikale Achse gewünschte bzw. hinsichtlich des Wellengangs akzeptable Durchmesser des Turms geringer sind und weniger voneinander abweichen. Außerdem kann sich dadurch eine erwünschte Sollbruchstelle in der Nähe des Meeresbodens ergeben.Among other things, this solution is available if the stiffness of the structure or the material requirement is due to additional Support in sufficient Distance should be improved during the under soil mechanics Considered dimensions of the pile diameter and the one for transmission of torques about a vertical axis or with respect to the Waves acceptable diameter of the tower are less and less differ from each other. Moreover can result in a desired Breakage point nearby of the seabed.
Vorteilhaft erscheinen Ausführungen
mit zwei oder drei zusätzlichen
Stützen
in einem Quadranten neben der durchlaufenden Stütze. Dagegen wäre es für die statische
Wirksamkeit (Hebelarm) nicht sinnvoll, die durchlaufende Stütze (
Die aus dem Pfahl fortgesetzte Stütze kann abschnittsweise
konisch ausgebildet sein. Dadurch kann gegebenenfalls im Fachwerkteil
eine weitgehend symmetrische Tragstruktur mit drei identischen Stützen erreicht
werden, deren Mittelpunkt jedoch gegenüber der Achse des Pfahls versetzt
wäre. Vorteilhaft
könnte
auch ein durchwegs größerer Durchmesser
der aus dem Pfahl fortgesetzten Stütze sein, der damit vorteilhaft
Drehmomente um die Turmachse aufnehmen und in das Fundament leiten
könnte. Für die anderen
Stützen
(
Eine konische Form der durchgehenden Hauptstütze im Bereich
des Einbindens der anderen Stützen
(
Ein entsprechendes Vorgehen ist auch an der Oberseite eines Fachwerkabschnitts möglich, an die sich dann oben ein Rohrturm anschließt (Anspruch 3).A corresponding procedure is also possible at the top of a truss section, which then adjusts to the top a pipe tower connects (Claim 3).
Der Übergang Fachwerk-Rohrturm könnte vorteilhaft knapp unterhalb des Bewegungsraums der Flügelspitzen vorgenommen werden, um Verbiegungen der Flügel in Richtung Turm nicht durch eine breitere Fachwerkkonstruktion einzuschränken. Wenn die Fachwerkkonstruktion jedoch in die Höhe des Drehkreises der Flügel hineinragt, kann es sinnvoll sein, den (oberen) Rohrturm, der sich unten aus einer der Fachwerkstützen entwickelt, etwas geneigt anzuordnen, so dass das obere Ende des Rohrturms mittig zu dem Fachwerkabschnitt liegt, und somit auch die Drehbewegung der Gondel um die gemeinsame Achse von Rohrturm und Fachwerkabschnitt erfolgt. Der Drehkranz der Gondel wäre wieder horizontal. Dann würden die Drehkreise der Flügel je nach Windrichtung denselben Abstand zu den Ecken der Fachwerkkonstruktion aufweisen, während bei axial zu einer Stütze angeordnetem Rohrturm bei den übrigen Fachwerkstützen der Abstand geringer wäre als zu der durchlaufenden Stütze.The transition from truss to tubular tower could be beneficial be made just below the range of movement of the wing tips, to bend the wings towards the tower not through a wider truss structure limit. If however, the framework construction projects into the height of the turning circle of the wings, it can make sense to remove the (upper) tubular tower, which is made up of a of the truss columns designed to arrange something inclined so that the top of the Pipe tower is centered on the truss section, and thus also the rotation of the gondola around the common axis of the tube tower and truss section. The slewing ring of the gondola would be back horizontal. Then would the turning circles of the wings depending on the wind direction, the same distance from the corners of the truss structure have while at axial to a prop arranged pipe tower with the rest Truss supports the distance would be less than to the continuous support.
Gegebenenfalls kann eine Überleitung einer kreisförmigen Rohrform des durchgehenden Pfahls in eine andere Profilform, etwa ein Vierkantrohr, vorgenommen werden, etwa wenn eine Kreisform zwar im Bereich des Einzelrohrturms aus Tragfähigkeitsgründen erforderlich ist und Fachwerks aus Fertigungsgründen eine andere Profilform bevorzugt wird.If necessary, a transfer of a circular tube shape of the continuous pile into another profile shape, for example a square tube, can be carried out be taken, for example if a circular shape is required in the area of the single tube tower for reasons of load-bearing capacity and a different profile shape is preferred for manufacturing reasons.
Um nicht durch Rammstöße eine Befestigungsstelle zu beschädigen, bzw. dort das Material zu ermüden, könnte an dem einzurammenden Pfahl ein Flansch in hinreichendem Abstand zu der Aufschlagfläche des Rammgeräts angeordnet werden (Anspruch 4). Bei außen angeordetem Flansch unterhalb der Rammfläche hätte das anschließende Turmsegment dann einen größeren Durchmesser, und würde das durch Rammstöße deformierte obere Ende des Pfahls umschließen.Not by ramming one Damage the attachment point, or to tire the material there, could a flange at a sufficient distance from the pile to be driven to the impact area of the pile driver be arranged (claim 4). With the flange located outside the driving surface would have that subsequent tower segment then a larger diameter, and would deformed by ramming enclose the top of the pile.
Falls der Rammvorgang durch die Masse der seitlich befestigten Fachwerkkonstruktion beeinträchtigt wird, könnte vorübergehend eine Ausgleichsmasse an der anderen Seite des Turms befestigt werden.If the ramming process through the mass the laterally attached truss structure is impaired, could temporarily a leveling compound must be attached to the other side of the tower.
Gegebenenfalls könnte die Abzweigung zum Fachwerk bis unter das normale Niveau des Meeresbodens eingebracht werden, so dass nach Wiederverfüllung nur noch die Fachwerkstreben aus dem Meeresboden ragen, die evtl. geringere Kolkung verursachen als der größere Rohrpfahl. Dies könnte z. B. durch Freispülen des Verzweigungsbereiches während des Rammvorgangs ermöglicht werden.If necessary, the branch to the truss brought in below the normal level of the sea floor, so after refilling only the truss struts protrude from the sea floor, which may cause less scouring than the larger tubular pile. This could e.g. B. by flushing of the branch area during of the ramming process become.
