Description
Die Erfindung betrifft ein Abstützelement, insbesondere für Turmfundamente.The invention relates to a support element, in particular for tower foundations.
Aus der Praxis ist es bekannt, schwingende Maschinenelemente mittels sogenannter Silent-Elemente zu befestigen, die einen Gummikörper umfassen, der zwischen zwei Metallplatten vulkanisiert ist, um diese elastisch miteinander zu verbinden.From practice it is known to fasten vibrating machine elements by means of so-called silent elements which comprise a rubber body which is vulcanised between two metal plates in order to elastically connect them together.

Elemente der genannten Art können Zugkräfte oder Druckkräfte übertragen. Sie können zur Abstützung schwingender Lasten genutzt werden. Allerdings stellt der Gummi-Metall-Verbund eine Schwachstelle dar, die zum Versagen des Bauteils führen kann. Dies gilt insbesondere bei hohen Drucklasten, die zu einem bezüglich der Kraftwirkungsrichtung seitlichen Ausweichen des Elastomerkörpers und somit zu Scherkräften an dem Gummi-Metall-Verbund führen. Auch eignen sich solche Gummi-Metall-Verbundelemente kaum zum Ersatz mechanischer Federn.Elements of the type mentioned can transmit tensile forces or compressive forces. They can be used to support oscillating loads. However, the rubber-metal composite is a weak point, which can lead to failure of the component. This is especially true at high pressure loads, which lead to a side of the elastomer body with respect to the force acting direction and thus to shear forces on the rubber-metal composite. Also, such rubber-metal composite elements are hardly suitable for replacing mechanical springs.
Es ist Aufgabe der Erfindung, ein Abstützelement zu schaffen, das für hohe Drucklasten geeignet ist und eine hohe Lastwechselfestigkeit aufweist.It is an object of the invention to provide a support element which is suitable for high pressure loads and has a high fatigue strength.
Diese Aufgabe wird mit dem Abstützelement nach Anspruch 1 gelöst:This object is achieved with the support element according to claim 1:
Das erfindungsgemäße Abstütz- und Federelement umfasst einen aus einem Polyurethan-Elastomere-Kunststoff bestehenden Körper, der zwei voneinander weg weisende Flachseiten aufweist. An den Flachseiten sind Verbundmaterialschichten angebracht, die Kohlenstofffasern enthalten, die in eine Kunststoffmatrix eingebettet sind, wobei die Verbundmaterialschichten durch ein Prepreg-Material gebildet sind, die mit dem Körper unter gleichzeitiger Anwendung von Anpressdruck und Wärme verbunden und dabei ausgehärtet worden sind. Das Element kann ein Sandwich, bestehend aus zwei Verbundmaterialschichten und dem dazwischen angeordneten Körper, wie auch ein aus mehreren Schichten und mehreren Körpern bestehender Verbundaufbau sein. Unabhängig davon bilden die Verbundmaterialschichten steife Platten, zwischen denen der Körper aus Polyurethan-Kunststoff angeordnet ist. Zwischen dem Polyurethan-Kunststoff und den Verbundmaterialschichten ist eine intensive stoffschlüssige Verbindung, d. h. Verschmelzung gegeben. Aufgrund des nahezu gleichen Temperaturausdehnungskoeffizienten der Verbundmaterialschichten und des aus Polyurethankunststoff bestehenden Körpers kann dieser relativ groß ausgebildet werden, ohne dass selbst bei extremen Temperaturschwankungen eine Lösung der Verbundmaterialschichten von dem Körper zu befürchten wären. Außerdem stellt sich heraus, dass zwischen einer Kunststoffmatrix und dem Polyurethan-Kunststoff ein inniger Verbund herstellbar ist, der durch die seitliche Ausweichbewegung des Polyurethankörpers bei Druckbelastung nicht abreißt. Das erfindungsgemäße Abstützelement ist deshalb zur dauerhaften Abstützung großer Lasten, beispielsweise im Baumaschinenbereich, insbesondere zur Abstützung von Türmen von Windkraftanlagen und Bearbeitungszentren geeignet. Es lässt sich auf rationelle Weise herstellen, indem auf Flachseiten eines zuvor bereitgestellten Polyurethankörpers Schichten aus Prepreg-Material aufgelegt werden, die unter gleichzeitiger Anwendung von Druck und Wärme mit dem Körper verbunden und zugleich ausgehärtet werden. Das Anpressen und Aushärten des Prepreg-Materials kann beispielsweise im beheizten Vakuumsack erfolgen. Bei einem verfeinerten Verfahren wird das Element zum Aushärten zwischen ebene Flächen als Sandwich mit einer Kraft eingespannt, die den Polyurethankörper merklich verformt. Vorzugsweise ist die Kraft kleiner als die von dem Element zu ertragende maximale axiale Kraft. Weiter vorzugsweise ist die Kraft größer als ein Viertel, besser größer als ein Drittel oder die Hälfte der maximalen axialen Kraft. Dadurch wird das Prepregmaterial zusammengepresst. An seiner nach außen gewandten Seite passt es sich an die ebene Flächen an, an denen es anliegt. Die Grenzfläche zwischen dem Prepreg und dem Körper wird infolge der Gewebestruktur des Fasermaterials wellig. Außerdem weicht der Körper durch den axialen Druck radial etwas aus. In diesem Zustand wird die Verklebung zwischen dem Körper und den Verbundmaterialschichten hergestellt. Dadurch wird die Grenzschicht nach Entlasten des Sandwiches in Radialrichtung negativ vorgespannt. Dadurch wird bei einer späteren Widerbelastung die Spannung zunächst Null und dann positiv. Der maximale Betrag der radialen Kraft wird durch die Vorspannung jedoch gemindert und im guten Fall sogar halbiert. Dies macht die Verbundelemente dauerschwingfest und hoch belastbar. Außerdem haben die Elemente als Federn eine hohe Wiederkehrgenauigkeit. Die vollflächige Verbindung zwischen dem Körper und den Verbundmaterialschichten bleibt dauerhaft erhalten. Mikrorisse in der Grenzschicht, die sonst zu lokalen Kriecherscheinungen mit Stick-Slip-Effekten führen, können unterbunden werden.The supporting and spring element according to the invention comprises a body consisting of a polyurethane-elastomeric plastic which has two flat sides facing away from one another. On the flat sides, layers of composite material containing carbon fibers embedded in a plastic matrix are formed, the composite material layers being formed by a prepreg material which has been bonded to the body while applying contact pressure and heat and thereby cured. The element may be a sandwich consisting of two layers of composite material and the body therebetween, as well as a composite structure consisting of several layers and several bodies. Independently, the composite material layers form rigid plates, between which the body is made of polyurethane plastic. Between the polyurethane plastic and the composite material layers is an intensive cohesive connection, ie given fusion. Due to the nearly same coefficient of thermal expansion of the composite material layers and the existing polyurethane plastic body this can be made relatively large, without a solution of the composite material layers would be feared by the body even under extreme temperature fluctuations. In addition, it turns out that between the plastic matrix and the polyurethane plastic, an intimate bond is produced, which does not break off by the lateral evasive movement of the polyurethane body under pressure. The support element according to the invention is therefore suitable for the permanent support of large loads, for example in the construction machinery sector, in particular for supporting towers of wind turbines and machining centers. It can be produced in a rational manner by laying on flat sides of a previously provided polyurethane body layers of prepreg material, which are connected with the simultaneous application of pressure and heat to the body and cured at the same time. The pressing and curing of the prepreg material can be done for example in the heated vacuum bag. In a refined process, the hardening element is sandwiched between flat surfaces by a force that appreciably deforms the polyurethane body. Preferably, the force is less than the maximum axial force to be borne by the element. More preferably, the force is greater than a quarter, more preferably greater than a third or half of the maximum axial force. As a result, the prepreg material is compressed. On its outward-facing side, it adapts to the flat surfaces on which it rests. The interface between the prepreg and the body becomes wavy due to the fabric structure of the fiber material. In addition, the body differs slightly radially by the axial pressure. In this state, the bond is between the body and the composite layers. As a result, the boundary layer is negatively biased after relieving the sandwich in the radial direction. As a result, the voltage is initially zero and then positive at a later reversal. The maximum amount of radial force is mitigated by the bias and in the best case even halved. This makes the composite elements durable swinging and high load capacity. In addition, the elements have a high recurrence accuracy as springs. The full-surface connection between the body and the composite material layers is permanently retained. Microcracks in the boundary layer, which otherwise lead to local creep phenomena with stick-slip effects, can be prevented.
Die Welligkeit der Grenzfläche zwischen dem Körper und den Verbundmaterialschichten kann noch zu einer formschlüssigen Unterstützung der mechanischen Verbindung und zu einer verbesserten Abstützung der in Radialrichtung in der Grenzfläche wirkenden Kräfte führen. Vorzugsweise sind die Kohlenstofffasern der Verbundmaterialschichten einander überkreuzend angeordnet. Beispielsweise liegen sie als Gewebe vor.The waviness of the interface between the body and the layers of composite material may still result in positive engagement of the mechanical connection and improved support of the forces acting radially in the interface. Preferably, the carbon fibers of the composite material layers are arranged crossing one another. For example, they are present as tissue.
Das Prepreg-Material kann im Weiteren ein Kunstharz enthalten, wie beispielsweise Polyesterharz oder ein sonstiges Harz.The prepreg material may further contain a synthetic resin such as polyester resin or other resin.
Die Verbundmaterialschichten sind vorzugsweise wesentlich dünner als der Körper. Sie besitzen somit trotz ihrer in Faserlängsrichtung gegebenen extremen Zugsteifigkeit eine gewisse elastische Biegsamkeit, so dass sie sich an im Baubereich vorhandene Metall- oder Betonelemente anschmiegen können. Vorzugsweise ist die Dicke der Verbundmaterialschichten deutlich geringer als ein Zehntel der Dicke des Körpers. Der Körper kann als Zylinder, Hohlzylinder, Prisma, mit einem Durchgang versehenes Prisma oder dergleichen, ausgebildet sein. Vorzugsweise ist er dabei ringförmig.The composite material layers are preferably substantially thinner than the body. Thus, despite their extreme tensile stiffness in the fiber longitudinal direction, they have a certain elastic flexibility, so that they can cling to existing metal or concrete elements in the construction sector. Preferably, the thickness of the composite material layers is significantly less than one tenth of the thickness of the body. The body may be formed as a cylinder, a hollow cylinder, a prism, a prism provided with a passage, or the like. Preferably, it is annular.
