Description

Die Erfindung betrifft eine Befestigungsanordnung am Rand eines steinartigen Bauwerksteils mit den Merkmalen des Oberbegriffs des Anspruchs 1 sowie ein Verfahren zur Herstellung einer derartigen Befestigungsanordnung mit den Merkmalen des Oberbegriffs des Anspruchs 6. Mit "steinartig" ist ein Werkstoff aus Stein, Ziegel, Beton, auch Gasbeton, und dgl. gemeint. Insbesondere handelt es sich um Beton. Mit "Bauwerksteil" wird zum Ausdruck gebracht, dass die Befestigung an einem Bauwerk erfolgt. Die Erläuterung der Erfindung erfolgt anhand Beton ohne die Erfindung auf diesen Werkstoff zu beschränken.The invention relates to a mounting arrangement on the edge of a stone-like structure part with the features of the preamble of claim 1 and a method for producing such a fastening arrangement with the features of the preamble of claim 6. With "stone-like" is a material of stone, brick, concrete, too Gas concrete, and the like. Meant. In particular, it is concrete. The term "structural part" expresses that it is attached to a structure. The explanation of the invention is based on concrete without the invention to be limited to this material.

Es ist bekannt, Bauteile mit beispielsweise Dübeln oder Ankern in einem Bohrloch in einem Bauwerksteil zu befestigen, d.h. im Bauwerksteil zu verankern. Bei einer Querbeanspruchung der Verankerung ist eine mögliche Versagensart ein Spalten des Bauwerksteils. Insbesondere bei einer randnahen Verankerung ist die Gefahr eines Spaltens des Bauwerksteils hoch. Durch einen ausreichenden Randabstand der Verankerung wird das Risiko eines Versagens durch Spalten des Bauwerksteils vermieden oder jedenfalls verringert. Das Risiko des Spaltens des Bauwerksteils ist besonders groß bei einer Verankerung mit Spreizdübeln aufgrund der Spreizkraft. Günstiger, aber regelmäßig aufwendiger sind spreizdruckfreie Verankerungen. Ein typischer Anwendungsfall einer randnahen Verankerung mit hoher Querkraft ist die Verankerung von Geländern.It is known to fasten components with, for example, dowels or anchors in a borehole in a structural part, i. to anchor in the structural part. For a transverse load of the anchorage is a possible failure type a columns of the building part. Especially with a near-edge anchorage, the risk of splitting of the building part is high. Sufficient edge distance of the anchorage avoids or at least reduces the risk of failure by splitting the structural part. The risk of splitting of the building part is particularly great in anchoring with expansion dowels due to the spreading force. Cheaper, but regularly consuming are spreader pressure-free anchors. A typical application of anchoring close to the edge with high lateral force is the anchoring of railings.

Das Patent US-A 3,316,574 offenbart eine Dehnfuge einer Straßenbrücke, bei der ein elastisches Dehnungselement in stufenförmigen Taschen einander zugewandter Enden von Betonplatten einliegt. Befestigt ist das Dehnelement mit Betonankern in seinen Randbereichen. Unter dem Dehnelement kann ein S-förmig abgekantes blech als reibungsmindernde Unterlage angeordnet sein, das an den Betonankern befestigt ist. Die Unterlage ist stoffschlüssig im Bereich der Betonankern am Bauwerksteil angebracht und reicht bis zum Rand des Bauwerksteils. Es offenbart eine Befestigungsanordnung bzw. ein Verfahren zur Herstellung einer Befestigungsanordnung, die bzw. das die Merkmale des Oberbegriffes des Anspruchs 1 bzw. 5 aufweist.The Patent US-A 3,316,574 discloses an expansion joint of a road bridge in which an elastic expansion element rests in stepped pockets of facing ends of concrete slabs. The expansion element is fastened with concrete anchors in its edge areas. Under the expansion element, an S-shaped bent sheet metal can be arranged as a friction-reducing pad, which is attached to the concrete anchors. The base is firmly attached in the area of the concrete anchors on the building part and extends to the edge of the building part. It discloses a fastener assembly or a method of manufacturing a fastener assembly having the features of the preamble of claims 1 and 5, respectively.

Die europäische Patentanmeldung EP-A 1 033 455 offenbart das Aufkleben eines Karbonfaserbandes auf die Unter- und Zugseite eines Betonbalkens. Um ein Abplatzen des Betons an den Enden des Karbonfaserbandes zu verhindern, schlägt die Erfindung eine Verankerung mit einer Stahlplatte vor, die mit vier Durchsteckbolzen verschraubt ist, die im Beton verankert sind. Eine Verringerung einer Spaltwirkung oder einer Spaltgefahr der Gewindebolzen wird dadurch nicht erreicht.The European patent application EP-A 1 033 455 discloses the bonding of a carbon fiber tape on the lower and tension side of a concrete beam. To prevent the concrete from flaking off at the ends of the carbon fiber tape, the invention proposes anchoring with a steel plate bolted to four through bolts anchored in the concrete. A reduction of a splitting effect or a risk of splitting the threaded bolt is not achieved.

Das europäische Patent EP-B1 0 835 355 offenbart die Verbindung von Betonteilen eines Brückenbauwerks mit Gewebestreifen. Die Gewebestreifen können in Kehlbereichen mit Gewindebolzen befestigt sein, die durch Balken des Bauwerks gesteckt sind. Die Gewindebolzen entfalten keinerlei Spaltwirkung, der Betonbalken wird nicht gegen Spaltung gesichert.The European Patent EP-B1 0 835 355 discloses the joining of concrete parts of a bridge structure with fabric strips. The fabric strips can be secured in throat areas with threaded bolts that are inserted through beams of the building. The threaded bolts do not develop any splitting effect, the concrete beam is not secured against splitting.

Der Erfindung liegt die Aufgabe zugrunde, eine Befestigungsanordnung vorzuschlagen, die das Risiko des Versagens durch Spalten des Bauwerksteils bei randnaher Verankerung verringert.The invention has for its object to propose a mounting arrangement that reduces the risk of failure by splitting the structure part at near-edge anchoring.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 und des Anspruchs 5 gelöst. Die erfindungsgemäße Befestigungsanordnung weist eine Verstärkung auf, die durch Kleben im Bereich der Verankerung am Bauwerksteil angebracht ist und bis zu einem Rand des Bauwerksteils reicht. Die Verstärkung nimmt Zugkräfte des Bauwerksteils auf, die durch auf die Verankerung einwirkende Querkräfte und ggf. durch eine Spreizwirkung der Verankerung im Bauwerksteil wirken. Die Zugspannungen im Bauwerksteil und damit die Gefahr einer Spaltung sind verringert. Der Stoffschluss zwischen Verstärkung und Bauwerksteil verteilt eine Übertragung der im Bauwerksteil wirkenden Kräfte auf die Verstärkung und umgekehrt über die Fläche der Verstärkung und wird deswegen als günstig für die Kraftübertragung angesehen. Außerdem ist die Anbringung der Verstärkung ohne Bohren oder sonstige Schwächung des Bauwerksteils möglich. Die erfindungsgemäße Befestigungsanordnung ist selbstverständlich auch im Bereich einer Ecke eines Bauwerksteils möglich, wo zwei Ränder aufeinander stoßen.This object is achieved by the features of claim 1 and claim 5. The fastening arrangement according to the invention has a reinforcement, which is attached by gluing in the region of the anchoring to the building part and extends to an edge of the building part. The reinforcement absorbs tensile forces of the structural part, which act by transverse forces acting on the anchoring and possibly by a spreading effect of the anchoring in the structural part. The tensile stresses in the structural part and thus the risk of splitting are reduced. The material connection between reinforcement and structural part distributes a transfer of the forces acting in the structural part on the reinforcement and vice versa over the area of the reinforcement and is therefore regarded as favorable for the power transmission. In addition, the attachment of the reinforcement without drilling or other weakening of the structural part is possible. The fastening arrangement according to the invention is of course also possible in the region of a corner of a building part, where two edges abut each other.

Eine Ausgestaltung der Erfindung sieht eine Faserverstärkung als Verstärkung vor. Beispielsweise ist eine Fasermatte (Gelege, Gewebe, Gewirk, Gestrick etc.) auf das Bauwerksteil aufgeklebt. Insbesondere ist eine Faserrichtung quer zum Rand des Bauwerksteils vorgesehen. Durch die Faserverstärkung wird eine hohe Zugbelastbarkeit der Verstärkung erreicht. Außerdem passt sich die Faserverstärkung an die Oberfläche des Bauwerksteils an.An embodiment of the invention provides a fiber reinforcement as reinforcement. For example, a fiber mat (scrim, fabric, knitted fabric, knitted fabric, etc.) is glued to the building part. In particular, a fiber direction is provided transversely to the edge of the building part. Due to the fiber reinforcement is a high tensile strength the gain achieved. In addition, the fiber reinforcement adapts to the surface of the building part.

Vorzugsweise erstreckt sich die Verstärkung in einer Richtung von der Verankerung weg vom Rand des Bauwerksteils nach innen. Durch eine großflächige und weit nach innen reichende Verstärkung wird die Gefahr des Spaltens des Bauteils verringert. Eine Weiterbildung der Erfindung sieht vor, dass die Verstärkung um eine Kante am Rand des Bauwerksteils auf eine Randfläche reicht, die einer Verankerungsfläche benachbart ist. Die Verankerungsfläche ist die Fläche, in der die Verankerung angebracht ist. Indem die Verstärkung auch auf der Randfläche aufgebracht ist und auf die Verankerungsfläche reicht, wird die Gefahr eines Spaltens des Bauteils weiter verringert.Preferably, the reinforcement extends inwardly in a direction away from the anchorage away from the edge of the structural member. A large and far inward reinforcement reduces the risk of splitting of the component. A development of the invention provides that the reinforcement extends around an edge on the edge of the building part to an edge surface which is adjacent to an anchoring surface. The anchoring surface is the surface in which the anchoring is attached. By the reinforcement is also applied to the edge surface and extends to the anchoring surface, the risk of splitting of the component is further reduced.

Das erfindungsgemäße Verfahren mit den Merkmalen des Anspruchs 5 sieht vor, dass die Verstärkung in einem die Verankerung umgebenden Bereich am Bauwerksteil aufgeklebt wird, bis zum Rand des Bauwerksteils reicht und dass die Verankerung in der Verstärkung im Bauwerksteil angebracht wird. Vorzugsweise, jedoch nicht zwingend, wird zuerst die Verstärkung und danach die Verankerung angebracht.The method according to the invention with the features of claim 5 provides that the reinforcement is adhered to the structural part in a region surrounding the anchoring, extends to the edge of the structural part and that the anchoring is applied in the reinforcement in the structural part. Preferably, but not necessarily, first the reinforcement and then the anchoring is applied.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt eine perspektivische Darstellung einer erfindungsgemäßen Befestigungsanordnung.The invention will be explained in more detail with reference to an embodiment shown in the drawing. The single FIGURE shows a perspective view of a fastening arrangement according to the invention.

Die in Figur 1 dargestellte, erfindungsgemäße Befestigungsanordnung 1 ist am Rand eines Bauwerksteils 2 angeordnet. Das Bauwerksteil 2 besteht aus Beton, der armiert sein kann. Das Bauwerksteil 2 kann beispielsweise eine Balkon- oder Terrassenplatte oder der Übergang von einer Dach- zu einer Wandfläche sein. Eine Oberseite des Bauwerksteils 2 wird zur Erläuterung der Erfindung nachfolgend als Verankerungsfläche 3 bezeichnet werden, weil in ihr eine Verankerung 4 erfindungsgemäß angebracht ist. Eine über eine Kante 5 angrenzende Fläche des Bauwerksteils 2 wird nachfolgend als Randfläche 6 bezeichnet werden. Die Kante 5 und die Randfläche 6 stellen einen Rand der Verankerungsfläche 3 und des Bauwerksteils 2 dar.In the FIG. 1 illustrated, inventive fastening assembly 1 is disposed on the edge of a building part 2. The building part 2 consists of concrete, which can be reinforced. The building part 2 may be, for example, a balcony or terrace slab or the transition from a roof to a wall surface. An upper side of the building part 2 will be referred to below as anchoring surface 3 to explain the invention, because in it an anchorage 4 is mounted according to the invention. An area of the building part 2 which adjoins an edge 5 will be referred to below as the edge area 6. The edge 5 and the edge surface 6 represent an edge of the anchoring surface 3 and the structural part 2.

Die Verankerung 4 weist einen Anker 7 in Form einer Gewindestange auf. Der Anker 7 ist in einem in der Zeichnung nicht sichtbaren Bohrloch im Bauwerksteil 2 mittels eines Kunstharzmörtels verankert, d.h. stoffschlüssig befestigt. Grundsätzlich ist auch eine andere Verankerung mit beispielsweise einem (Spreiz-)Dübel oder einem Hinterschnittanker möglich (nicht dargestellt). Die Verankerung ist randnah angeordnet, worunter ein Randabstand von etwa 30 mm bis 50 mm zu verstehen ist. Auch bei einem größeren (oder auch kleineren) Randabstand ist die erfindungsgemäße Befestigungsanordnung möglich. Randnah im Sinne der Erfindung ist weniger als absoluter Randabstand zu verstehen als vielmehr durch die Gefahr eines Spaltens des Bauwerksteils 2 bei einer Querbeanspruchung des Ankers 7 bestimmt, also durch die Gefahr eines Abplatzens eines Bruchstücks vom Bauwerksteil 2 zusammen mit dem Anker 7 infolge einer Querbeanspruchung mit dem Anker 7. Bei großem Randabstand besteht diese Gefahr nicht oder ist jedenfalls sehr gering.The anchor 4 has an anchor 7 in the form of a threaded rod. The anchor 7 is anchored in a non-visible in the drawing hole in the building part 2 by means of a synthetic resin mortar, i. firmly attached. In principle, another anchoring with, for example, a (spreading) dowel or an undercut anchor is possible (not shown). The anchoring is arranged close to the edge, which is to be understood as an edge distance of about 30 mm to 50 mm. Even with a larger (or smaller) edge distance the mounting arrangement according to the invention is possible. Near the edge in the context of the invention is less than absolute edge distance to be understood as determined by the risk of splitting of the structural part 2 at a transverse load of the armature 7, so by the risk of chipping off a fragment of the building part 2 together with the armature 7 due to a transverse load the anchor 7. At high edge distance, this danger is not or is very low anyway.

Im Bereich der Verankerung 4 ist eine Verstärkung 8 stoffschlüssig am Bauwerksteil 2 angebracht. Die Verstärkung 8 ist eine Faserverstärkung, sie weist eine Fasermatte (Fasergelege) 9 auf. Die Fasern können beispielsweise Glas-, Kohle-, Kunststoff- oder Metallfasern sein. Die Fasermatte 9 umgibt die Verankerung 4, sie ist um die Kante 5 auf die Randfläche 6 des Bauwerksteils 2 umgelegt. Auf der Verankerungsfläche 3 reicht die Fasermatte 9 von der Kante 5, also vom Rand des Bauwerksteils 2, über die Verankerung 4 hinweg nach innen. Die Fasermatte 9 ist mit dem Kunstharzmörtel 10 getränkt und durch ihn mit dem Bauwerksteil 2 stoffschlüssig verbunden. Befindet sich die Verankerung 4 im Bereich einer Ecke des Bauwerksteils 2, wird die Verstärkung 8 von der Verankerungsfläche 3 auf beide angrenzenden, die Ecke bildenden Randflächen gelegt und aufgeklebt (nicht dargestellt). Die Verankerung 4 dient beispielsweise zur Befestigung eines nicht dargestellten Geländers, sie kann einer quer zum Rand oder vom Rand weg gerichteten Querbeanspruchung ausgesetzt sein. Die Verstärkung 8 verringert das Risiko eines Spaltens des Bauwerksteils 2 bei einer solchen Querbeanspruchung der Verankerung 4, die Verankerung 4 kann näher am Rand des Bauwerksteils 2 angeordnet werden.In the area of the anchoring 4, a reinforcement 8 is firmly attached to the building part 2. The reinforcement 8 is a fiber reinforcement, it has a fiber mat (fiber fabric) 9. The fibers may be, for example, glass, carbon, plastic or metal fibers. The fiber mat 9 surrounds the anchoring 4, it is folded around the edge 5 on the edge surface 6 of the building part 2. On the anchoring surface 3, the fiber mat 9 extends from the edge 5, ie from the edge of the building part 2, over the anchoring 4 away inside. The fiber mat 9 is connected to the synthetic resin mortar 10th soaked and connected by him with the building part 2 cohesively. If the anchoring 4 is located in the region of a corner of the building part 2, the reinforcement 8 is laid by the anchoring surface 3 on both adjacent edge surfaces forming the corner and glued (not shown). The anchorage 4 is used, for example, for attaching a railing, not shown, it may be exposed to a transversely directed to the edge or edge away lateral stress. The reinforcement 8 reduces the risk of splitting of the structural part 2 in such a transverse stress of the anchorage 4, the anchorage 4 can be arranged closer to the edge of the structural part 2.

Die Herstellung der Befestigungsanordnung 1 erfolgt erfindungsgemäß, indem die Fasermatte 9 auf die Verankerungsfläche 3 und die Randfläche 6 aufgeklebt, ein Loch für die Ankerstange 7 gebohrt und die Ankerstange 7 mit einem Kunstharzmörtel im Bohrloch verankert wird. Es kann auch umgekehrt zuerst die Verankerung 4 hergestellt und anschließend die Verstärkung 8 auf das Bauwerksteil 2 aufgeklebt werden. Eine Faserrichtung wird vorzugsweise so gewählt, dass Fasern der Verstärkung 8 in etwa rechtwinklig zur Kante 5, also zum Rand des Bauwerksteils 2, verlaufen.The production of the fastening arrangement 1 is carried out according to the invention by the fiber mat 9 glued to the anchoring surface 3 and the edge surface 6, drilled a hole for the anchor rod 7 and the anchor rod 7 is anchored in the borehole with a synthetic resin mortar. Conversely, it is also possible first to produce the anchoring 4 and then to glue the reinforcement 8 onto the structural part 2. A fiber direction is preferably selected such that fibers of the reinforcement 8 extend approximately at right angles to the edge 5, that is, to the edge of the building part 2.
