Abstract
Description
Stand der Technik Unterwassertürme können so konstruiert sein, daß sie mit einem einzigen Fuß gelenkig am Meeresboden verankert sind und allein durch ihren Schwimmauftrieb in senkrechter Lage gehalten werden und dann bei Wasserströmung oder Wellengang in berechenbarem Maße sich neigen oder um das Fußgelenk pendeln.Prior art underwater towers can be constructed so that they are articulated to the seabed with a single foot and go through alone their buoyancy are kept in a vertical position and then with a water current or waves lean to a predictable extent or swing around the ankle.
Gesucht wird ein Gelenklager, das große Normal- und Querkräfte aufnehmen kann, bei bekanntem Drehwinkel nur ein geringes Biegemoment erzeugt und innen einen Hohlraum besitzt, in dem Leitungen geführt werden, und der jederzeit zugänglich ist.We are looking for a spherical plain bearing that can absorb large normal and transverse forces can only generate a small bending moment with a known angle of rotation and one inside Has a cavity in which cables are guided and which is accessible at all times is.
Bekannt sind die Neoprene-Bnickenl ager der Firmen Gumba, Vorspanntechnik u.a. Diese Neoprene Lager sind flache Quader; sie besitzen eine Bewehrung aus dünnen Blechen. Sie können beträchtliche Normalkräfte ertragen und sind in dieser Richtung sehr steif. In den Querrichtungen sind sie weich elastisch und ermöglichen eine beträchtliche Verschiebung, wobei eine berechenbare Querkraft entsteht.The neoprene bracket bearings from Gumba, Prestressing Technology, are well known i.a. These neoprene bearings are flat cuboids; they have a thin reinforcement Sheet metal. They can endure considerable normal forces and are in that direction very stiff. In the transverse directions, they are soft and elastic and allow a considerable displacement, resulting in a predictable shear force.
Beschreibung der Erfindung Bild 1 zeigt den Querschnitt des Lagers.Description of the invention Figure 1 shows the cross-section of the bearing.
Der untere Körper ist das auf dem Meeresboden stehende Fundament, besteht aus Beton oder Stahl oder anderem beliebigem Material, ist massiv oder mit beliebigen Hohlräumen versehen, die wahlweise mit Ballast, Wasser oder Dmckluft gefüllt sind oder entspannte Luft enthalten oder zugänglich sind. Der obere Körper ist der pendelnde Turm oder ein Bein eines mehrteiligen Bauwerks, er besteht ebenso aus Beton oder Stahl oder beliebigem Material, und er ist von oben her zugänglich.The lower body is the foundation standing on the sea floor, consists of concrete or steel or any other material, is solid or with provided any cavities, which can optionally be filled with ballast, water or compressed air are filled or contain relaxed air or are accessible. The upper body is the pendulum tower or a leg of a multi-part structure, it also exists made of concrete or steel or any material, and it is accessible from above.
Zwischen dem Fundament und dem Turmschaft liegt ein ringförmiges elastisches Gelenk, welches wie die bekannten Neoprene-Brücklager aus mehreren Gummischichten und dazwischenliegenden Stahlblechen besteht.Between the foundation and the tower shaft there is an annular elastic Joint, which, like the well-known neoprene bridge bearing, consists of several layers of rubber and intermediate steel sheets.
Das kennzeichnende Merkmal ist: Die Lagerfugen und Bewehmngsbleche sind nicht eben und horizontal, sondern schräg und folgen genau oder ungefähr einer Kugelfläche oder einer Kegelfläche. Die Lote aller Lagerelemente schneiden sich genau oder annähernd in einem gemeinsamen Punkt. Die Steifheitsmatrix des Lagers ergibt sich aus einer genauen Berechnung. Der resultierende Drehpunkt liegt zwischen dem Schnittpunkt der Lote und dem Schnittpunkt der Tangenten, nach den Eigenschaften der genannten Neoprene-Lager liegt er nahe am Schnittpunkt der Lote.The distinguishing feature is: The horizontal joints and reinforcement sheets are not flat and horizontal, but sloping and follow exactly or approximately one Spherical surface or a conical surface. The perpendiculars of all bearing elements intersect exactly or approximately in a common point. The stiffness matrix of the bearing results from an exact calculation. The resulting pivot point is between the intersection of the perpendiculars and the intersection of the tangents, according to the properties of the aforementioned neoprene bearings, it is close to the intersection of the plumb bobs.
Der Lagerkörper kann aus mehreren Gummi steinen bestehen, die in Schichten, Säulen oder in einem Mauerverband angeordnet sind. In den Lagerfugen können entsprechend gebogene durchgehende Bleche liegen, die den Mauerverband zusammenhalten und die Querdehnung behindern. Wenn Fugen vorhanden sind, dann ist der ganze Gummikörper von einer weichen Gummischicht umhüllt, die ihn und den begehbaren Hohlraum gegen das Außenwasser abdichtet. Diese Dichtung funktioniert, wenn die Flächenpressung in den Fugen im ungünstigsten Zustand mit Sicherheit größer ist als der äußere Wasserdruck.The bearing body can consist of several rubber stones, which are laid out in layers, Columns or are arranged in a wall bond. In the horizontal joints can accordingly curved continuous sheets that hold the wall bond together and the Hinder transverse expansion. If there are joints, then is the whole The rubber body is encased in a soft rubber layer that covers it and the accessible cavity seals against the outside water. This seal works when the surface pressure in the joints in the most unfavorable condition is certainly greater than the external water pressure.
Für die Lastfäl le im Bauzustand, während des Absenkens des Turmes und im Endzustand, in denen keine genügende Auf last vorhanden ist, wird eine zugfeste Verbindung durch Spannstäbe erforderlich sein, die aus dem Spannbetonbau und grückenbau bekannt sind. Diese Spannstäbe sind biegsam, können auf eine berechenbare Länge elastisch pendeln, und ihre Gesamtlänge wird so berechnet, daß sie bei der Drehung des Gelenks nur begrenzte Dehnungsänderungen erfahren . Die Spannglieder können auch auf beliebigen Federkörpern verankert sein, und sind dann bei gleichem Drehwinkel entsprechend kürzer.For load cases during construction, while the tower is being lowered and in the final state, in which there is no sufficient load, a tensile strength becomes Connection by tie rods may be required, from prestressed concrete structures and bridges are known. These tie rods are flexible and can be made to a calculable length oscillate elastically, and their total length is calculated so that they are in rotation of the joint experience only limited elongation changes. The tendons can also be anchored on any spring bodies, and are then at the same angle of rotation correspondingly shorter.
Das hier beschriebene Gelenk kann über Wasser komplett hergestellt werden.The joint described here can be completely produced over water will.
Fundament und Turm werden schwimmend aneinander geführt, mit den genannten elastischen Spannstäben verbunden und dann gemeinsam zum Meeresboden abgesenkt.The foundation and tower are floating against each other, with the aforementioned elastic tension rods connected and then lowered together to the seabed.
Das Gelenk kann auch unter Wasser gekoppelt werden: Zunächst wird das Fundament auf den Meeresboden abgesetzt. Dann wird der Turm, dessen unteres Ende'mit einem Deckel verschlossen ist, schwimmend auf das Fundament gesetzt und mit einem Ballast so belastet, daß der Gummilagerring wasserdicht wird. Dann wird der Innenraum gelenzt, und das Lager kann von oben her betreten werden.The joint can also be coupled underwater: First, will the foundation set down on the seabed. Then the tower whose lower End 'is closed with a lid, set floating on the foundation and loaded with a ballast so that the rubber bearing ring becomes watertight. Then it will be the interior is pumped out and the warehouse can be entered from above.
Im Gelenk oder im Fundament unter dem Gelenk können beliebige Rohrleitungen, Kabel, Hebezeuge oder Aufzüge installiert werden. Diese besitzen unabhängige eigene Gelenke, damit sie die Pendelbewegung ohne Schaden mitmachen.Any pipes, Cables, hoists or elevators can be installed. These have independent own Joints so that they can participate in the pendulum movement without damage.
Bild 2 zeigt ein Gelenk, das aus 2 Gummiringen besteht, deren resultierende Drehpunkte in einem Punkt vereinigt sind. Dieses Gelenk ermöglicht einen größeren Drehwinkel.Figure 2 shows a joint that consists of 2 rubber rings, the resulting Pivot points are united in one point. This joint allows for a bigger one Rotation angle.
