Description
Die Erfindung betrifft eine Fassadenverankerung für eine höheneinstellbare Befestigung einer wärmegedämmten Fassade im Hochbau, bei der die Fassade von der Befestigung getragen oder gehalten wird, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a facade anchorage for a height-adjustable fastening of a thermally insulated facade in building construction, in which the facade is supported or held by the fastening, according to the preamble of
Die
In der
Im Hochbau sind Fassaden bekannt, die als Vorsatzschale ausgeführt sind. Bei diesen Fassaden werden beispielsweise Naturwerk- Beton- oder Klinkersteine als Mauerwerk vor eine tragende Struktur, nachfolgend Innenschale genannt, gesetzt und daran befestigt. Das Mauerwerk bildet die Vorsatzschale. Die Befestigung der Vorsatzschale an der Innenschale erfolgt häufig mit sogenannten Konsolankern, die üblicherweise jeweils ein Befestigungsteil aufweisen, das üblicherweise mit Dübeln oder Ankern an der Innenschale befestigt wird, und ein Tragteil, das direkt mit der Vorsatzschale verbunden ist und diese trägt. Üblicherweise bildet der Tragteil einen Kragarm, der das Eigengewicht der Vorsatzschale auf das Befestigungsteil überträgt. Befestigungs- und Tragteil werden dabei auf Zug und/oder Biegung belastet. Die Innenschale ist im Regelfall Teil eines beheizten Warmbereichs eines Baukörpers, so dass in diesem Fall zwischen der Fassade und der Innenschale eine Wärmedämmung angeordnet ist. Da die die Fassade tragende oder haltende Befestigung mit der beispielsweise aus Mauerwerk oder Beton bestehenden warmen Innenschale des Baukörpers verbunden ist, leitet sie einen Teil der Wärme von der warmen Innenschale in die kalte Fassade des Baukörpers. Die Befestigung bildet somit eine unerwünschte Wärmebrücke zur Fassade.In building construction, facades are known that are designed as facing. In these facades, for example, natural-made concrete or clinker bricks are placed as masonry in front of a supporting structure, hereinafter referred to as the inner shell, and attached to it. The masonry forms the facing shell. The attachment of the facing shell to the inner shell is often done with so-called bracket anchors, which usually each have a fastening part that is usually attached to the inner shell with dowels or anchors, and a support part that is directly connected to the facing shell and carries it. The supporting part usually forms a cantilever arm which transfers the weight of the facing shell to the fastening part. The fastening and supporting parts are subjected to tension and / or bending. As a rule, the inner shell is part of a heated, warm area of a building, so that in this case thermal insulation is arranged between the facade and the inner shell. Since the fastening carrying or holding the facade is connected to the warm inner shell of the building, which is made of masonry or concrete, for example, it conducts part of the heat from the warm inner shell into the cold facade of the building. The attachment thus forms an undesirable thermal bridge to the facade.
Die Aufgabe der Erfindung ist, diesen bekannten Nachteil zu vermeiden, und eine Fassadenverankerung zu offenbaren, bei der der Wärmefluss von der warmen Innenschale zur Fassade des Baukörpers weitgehend unterbunden ist.The object of the invention is to avoid this known disadvantage and to disclose a facade anchorage in which the flow of heat from the warm inner shell to the facade of the building is largely prevented.
Diese Aufgabe wird mit einer Fassadenverankerung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a facade anchoring with the features of
Die erfindungsgemäße Fassadenverankerung dient zur höheneinstellbaren Befestigung einer wärmegedämmten Fassade im Hochbau, bei der die Fassade von einer mit der Innenschale des Baukörpers verbundenen Befestigung getragen oder gehalten wird. "Höheneinstellbar" meint hier insbesondere, dass die Höhe, in der die Befestigung mit der Vorsatzschale verbunden ist, mit der Fassadenverankerung eingestellt werden kann. Die Fassadenverankerung kann hierzu relativ zur Innenschale bewegt werden. Eine Justierung der Höhe der Vorsatzschale selbst ist damit nicht gemeint, insbesondere kein Verschieben der fertig hergestellten Vorsatzschale mittels der Fassadenverankerung. Die Fassadenverankerung wird von einem Konsolanker gebildet. Erfindungsgemäß bestehen die auf Zug und/oder auf Biegung belasteten tragenden Bauteile des Konsolankers ganz oder teilweise aus einem den Wärmefluss hemmenden Material. Durch den Einsatz des den Wärmefluss hemmenden Materials wird erreicht, dass der Wärmeverlust durch den Konsolanker, reduziert, und somit die durch den Konsolanker gebildete Wärmebrücke verkleinert wird.The facade anchorage according to the invention is used for the height-adjustable fastening of a thermally insulated facade in building construction, in which the facade is supported or held by a fastening connected to the inner shell of the building. "Height adjustable" means here in particular that the height at which the fastening is connected to the facing shell can be adjusted with the facade anchoring. For this purpose, the facade anchorage can be moved relative to the inner shell. This does not mean an adjustment of the height of the facing shell itself, in particular no displacement of the finished facing shell by means of the facade anchoring. The facade anchorage is formed by a bracket anchor. According to the invention, the load-bearing components of the bracket anchor that are subjected to tension and / or bending are made entirely or partially of a material that inhibits the flow of heat. By using the material that inhibits the flow of heat, it is achieved that the heat loss through the bracket bracket is reduced, and thus the thermal bridge formed by the bracket bracket is reduced.
Als "Wärmefluss hemmend" wird hier ein Material bezeichnet, das eine mindestens um den Faktor 10 kleinere Wärmeleitfähigkeit aufweist, als das Material, aus dem die übrigen Teile des Konsolankers bestehen. Die Wärmeleitfähigkeit, das Vermögen eines Stoffs Energie in Form von Wäre zu transportieren, ist in diesem Zusammenhang definiert als der Wärmestrom, der einen Körper bestimmter Geometrie pro Zeiteinheit bei einem definierten Temperaturgefälle durchfließt. Beispielsweise wird die Wärmeleitfähigkeit λ für Edelstahl, aus dem Konsolanker typischerweise hergestellt sind, üblicherweise mit ungefähr 15 W/(m × K) angegeben. Dagegen liegen typische Dämmstoffe im Bereich unter 1,5 W/(m × K), insbesondere im Bereich unter 0,5 W/(m × K). Die Wärmeleitfähigkeit des den Wärmefluss hemmenden Materials ist erfindungsgemäß insbesondere um den Faktor 10 kleiner als die Wärmeleitfähigkeit von Edelstahl, insbesondere eines Edelstahls der Werkstoffnummer 1.4301. Das den Wärmefluss hemmende Material kann beispielsweise ein faserverstärkter Kunststoff sein, dessen Wärmeleitfähigkeit im Bereich von 0,3 W/(m × K) liegt, der aber im Vergleich zu Dämmmaterialien wie Glas- oder Steinwolle druckfest ist. Alternativ kann das den Wärmefluss hemmende Material ein Harz, insbesondere ein Epoxidharz sein, das ein kunststoffartiges Material bildet und eine Faserverstärkung aufweist. Die Faserverstärkung kann in diesem Fall insbesondere aus einer Glasfasermatte bestehen. In den Kunststoff beziehungsweise das Harz können den Wärmefluss hemmende Füllkörper eingebettet sein, beispielsweise Styroporhohlkugeln, vorzugsweise Glashohlkugeln, die den Wärmefluss gut hemmen, aber gleichzeitig eine im Vergleich zu Styroporhohlkugeln hohe Druckfestigkeit aufweisen.A material that has a thermal conductivity that is at least a factor of 10 lower than the material of which the other parts of the bracket are made is referred to here as "inhibiting heat flow". The thermal conductivity, the ability of a substance to transport energy in the form of heat, is defined in this context as the heat flow that flows through a body of a certain geometry per unit of time at a defined temperature gradient. For example, the thermal conductivity λ for stainless steel, from which bracket anchors are typically made, is usually given as about 15 W / (m × K). In contrast, typical insulation materials are in the range below 1.5 W / (m × K), especially in the range below 0.5 W / (m × K). According to the invention, the thermal conductivity of the material that inhibits the flow of heat is, in particular, a factor of 10 smaller than the thermal conductivity of stainless steel, in particular a stainless steel of material number 1.4301. The material that inhibits the flow of heat can be, for example, a fiber-reinforced plastic, the thermal conductivity of which is in the range of 0.3 W / (m × K), but which is pressure-resistant compared to insulating materials such as glass or rock wool. Alternatively, this can be the heat flow inhibiting material be a resin, in particular an epoxy resin, which forms a plastic-like material and has a fiber reinforcement. In this case, the fiber reinforcement can in particular consist of a glass fiber mat. In the plastic or the resin, fillers that inhibit the flow of heat can be embedded, for example hollow styrofoam spheres, preferably hollow glass spheres, which inhibit the flow of heat well but at the same time have a high compressive strength compared to hollow styrofoam spheres.
Vorzugsweise bestehen die tragenden Bauteile des Konsolankers aus einem Befestigungsteil und einem Tragteil. Insbesondere ist der Befestigungsteil und/oder der Tragteil relativ zur Innenschale beweg- und somit höheneinstellbar. Vorzugsweise besteht nur der Tragteil oder nur der Befestigungsteil aus einem den Wärmefluss hemmenden Material. Alternativ besteht der Tragteil und der Befestigungsteil aus einem den Wärmefluss hemmenden Material. Tragteil und Befestigungsteil können über eine Verklebung miteinander verbunden sein.The supporting components of the bracket anchor preferably consist of a fastening part and a supporting part. In particular, the fastening part and / or the support part can be moved relative to the inner shell and can thus be adjusted in height. Preferably, only the support part or only the fastening part consists of a material that inhibits the flow of heat. Alternatively, the support part and the fastening part are made of a material that inhibits the flow of heat. The support part and the fastening part can be bonded to one another.
Um bei möglichst kleinem Wärmefluss durch den Konsolanker ein möglichst gutes Tragverhalten des Konsolankers zu gewährleisten, bestehen bei einer bevorzugten Ausgestaltungsform die auf Zug und/oder Biegung belasteten Teile des Konsolankers, insbesondere der Befestigungsteil und/oder der Tragteil, ganz oder teilweise aus einem den Wärmefluss hemmenden Material mit einem Stahlkern.In order to ensure the best possible load-bearing behavior of the bracket anchor with the lowest possible heat flow through the bracket anchor, in a preferred embodiment the parts of the bracket anchor that are subjected to tension and / or bending, in particular the fastening part and / or the support part, consist entirely or partially of the heat flow retardant material with a steel core.
Der Stahlkern ist erfindungsgemäß blechförmig ausgebildet, seine Dicke ist also im Verhältnis zu den anderen Abmessungen relativ gering, und ist vorzugsweise von zwei den Wärmefluss hemmenden Isolierplatten ummantelt. Insbesondere weist der Stahlkern eine Dicke auf, die nicht oder nur unwesentlich größer als die Dicke der Isolierplatten ist. Beispielsweise weist der Stahlkern und jede der Isolierplatten eine Dicke von 10 Millimetern oder weniger auf. Der Tragteil bildet insbesondere eine Art Schwert, das zwischen zwei Wänden des Befestigungsteils, insbesondere zwischen zwei leistenförmig ausgebildeten Bauteilen des Befestigungsteils gehalten ist, derart, dass zwischen dem Stahlkern und dem Befestigungsteil jeweils eine der Isolierplatten angeordnet ist. Hierdurch ergibt sich ein Konsolanker mit guter Lastaufnahme und geringem Wärmefluss. Vorzugsweise sind der blechförmig ausgebildete Stahlkern und die den Wärmefluss hemmenden Isolierplatten über eine Verklebung und/oder formschlüssig mit oder ohne einem Verbindungsglied oder mit mehreren Verbindungsgliedern verbunden. Die Verbindung erfolgt erfindungsgemäß formschlüssig über zylindrisch ausgebildete Hülsen.According to the invention, the steel core is designed in the form of sheet metal, its thickness is therefore relatively small in relation to the other dimensions, and is preferably encased by two insulating plates which inhibit the flow of heat. In particular, the steel core has a thickness which is not or only slightly greater than the thickness of the insulating plates. For example, the steel core and each of the insulating plates has a thickness of 10 millimeters or less. The support part forms in particular a kind of sword which is held between two walls of the fastening part, in particular between two strip-shaped components of the fastening part, such that one of the insulating plates is arranged between the steel core and the fastening part. This results in a bracket anchor with good load absorption and low heat flow. The steel core, which is embodied in sheet-metal form, and the insulating plates which impede the flow of heat are preferably connected by means of an adhesive bond and / or in a form-fitting manner with or without a connecting link or with a plurality of connecting links. According to the invention, the connection is made in a form-fitting manner via cylindrical sleeves.
