Description

Vorgefertigtes Bauelement für GebäudePrefabricated building element
Beschreibungdescription
Die Erfindung betrifft ein vorgefertigtes Bauelement für Bauwerke, vorzugsweise im Fertigteilbau mit einem Kernelement und mindestens einem Zugkräfte aufnehmenden Verstärkungsteil.The invention relates to a prefabricated component for structures, preferably in prefabricated construction with a core element and at least one reinforcing part absorbing tensile forces.
Plattenförmige Bauelemente der eingangs angegebenen Art werden im Fer- tigteilbau als Wand- oder Deckenelemente verwendet. Üblicherweise enthalten sie einen Plattenkern aus Leichtbeton, der mit einem in die Beton- platte eingelegten Armierungsnetz verstärkt ist. Die Verstärkung hat die Aufgabe, die in den Decken- oder Wandelementen auftretenden Zug- bzw. Querkräfte aufzunehmen, während der Beton zur Aufnahme der Druckkräfte bestimmt ist. Durch Betonzusätze im Plattenkern können die Festigkeitswerte erhöht werden.Panel-shaped components of the type specified at the outset are used as prefabricated wall or ceiling elements. They usually contain a slab core made of lightweight concrete, which is reinforced with a reinforcing mesh inserted into the slab. The reinforcement has the task of absorbing the tensile or transverse forces occurring in the ceiling or wall elements, while the concrete is intended to absorb the compressive forces. The strength values can be increased by adding concrete in the slab core.
Bei den bekannten Bauelementen mit Armierungsnetzen wird als nachteilig empfunden, daß die Zugfestigkeit zu wünschen übrig läßt. Wegen der Poro- sität von Leichtbeton ist die Korrosionsanfälligkeit der aus Stahl bestehenden Armierungsnetze erhöht, so daß es frühzeitig zu Korrosionsschäden kommen kann. Schließlich ist auch die Bearbeitbarkeit problematisch, da es beim Durchbohren zu einer Unterbrechung der Armierung kommen kann, die zu Materialausbrüchen führt. Die Instabilität der bekannten vorgefertigten Bau- elemente macht auch ihre Handhabung beim Transport und auf der Baustelle problematisch.In the known components with reinforcing nets, it is felt to be disadvantageous that the tensile strength leaves something to be desired. Because of the porosity of lightweight concrete, the reinforcement nets made of steel are more susceptible to corrosion, so that corrosion damage can occur at an early stage. Finally, the machinability is also problematic since the reinforcement can be interrupted when drilling through, which leads to material breakouts. The instability of the known prefabricated components also makes them difficult to handle during transport and on the construction site.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die bekannten vorgefertigten Bauelemente dahingehend zu verbessern, daß sie mit einfa- chen Mitteln eine hohe Zugfestigkeit und Dauerhaftigkeit aufweisen und oh- ne Ausbruchgefahr transportierbar, auf der Baustelle handhabbar und bearbeitbar sind.Proceeding from this, the object of the invention is to improve the known prefabricated components in such a way that they have high tensile strength and durability with simple means and without ne can be transported, handled and processed on site.
Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.To achieve this object, the combination of features specified in claim 1 is proposed. Advantageous refinements and developments of the invention result from the subclaims.
Ein wesentliches Merkmal der Erfindung besteht darin, daß das Verstärkungsteil als Flachmaterialteil aus faserverstärktem Kunststoff ausgebildet ist, das an einer Breitseitenfläche des Kernelements form- und/oder stoffschlüssig fixiert ist. Als Flachmaterialteil kommt dabei eine schichtbildende Platte oder Folie in Betracht. Das Flachmaterialteil weist zweckmäßig eine Bindemittelmatrix aus Kunststoff und ein in diese eingebettetes Fasergewebe oder -gelege auf. Es ist auf mindestes eine der Breitseitenflächen des Kernelements vorzugsweise mit einem Epoxidharz-Kleber flächig aufgeklebt.An essential feature of the invention is that the reinforcing part is designed as a flat material part made of fiber-reinforced plastic, which is fixed to a broad side surface of the core element in a form-fitting and / or cohesive manner. A layer-forming plate or film can be considered as the flat material part. The flat material part expediently has a binder matrix made of plastic and a fiber fabric or scrim embedded in it. It is preferably glued to at least one of the broad side surfaces of the core element with an epoxy resin adhesive.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß das Flachmaterialteil eine Vielzahl von einseitig überstehenden, noppenartigen Verankerungsorganen aufweist, mit denen es durch Öffnungen in der Breitseitenflä- ehe hindurch in das Kernelement eingreift und dort formschlüssig verankert ist. Die Verankerungsorgane sind dabei in das Kernelement eingebettet. Bei der Herstellung des Bauelements werden die Flachmaterialteile in eine Schalung so gegen die Schalungswand angelegt, daß ihre Verankerungsorgane nach innen weisen und von Flüssigbeton umgössen werden. Vorteil- hafterweise besteht das Kernelement aus Beton, Leichtbeton, Gasbeton oder Gips.A preferred embodiment of the invention provides that the flat material part has a plurality of nub-like anchoring members projecting on one side, with which it engages through openings in the broad side surface and into the core element and is anchored there in a form-fitting manner. The anchoring elements are embedded in the core element. In the manufacture of the component, the flat material parts are placed in a formwork against the formwork wall in such a way that their anchoring members point inwards and are encased in liquid concrete. The core element advantageously consists of concrete, lightweight concrete, gas concrete or gypsum.

Bevorzugt besteht die Bindemittelmatrix aus einem Thermoplast der Gruppe Polyamid, Polymethylmethacrylat, Polyphenylensulfid, Polypropylen, Polye- thylenterephthalat, Polybutylenterefthalat, Polyetherimid, Styrol-Polymerisat, Polyetheretherketon. Die Fasern des Flachmaterialteils werden zweckmäßig aus der Gruppe Kohlenstofffasern, Glasfasern, Aramidfasern, Polyethylenfa- sern, Basaltfasern, Naturfasern ausgewählt.The binder matrix of the flat material can consist of a thermoset, for example from the group of epoxy resin, polyester resin, vinyl resin. The binder matrix preferably consists of a thermoplastic from the group consisting of polyamide, polymethyl methacrylate, polyphenylene sulfide, polypropylene, polye ethylene terephthalate, polybutylene terephthalate, polyetherimide, styrene polymer, polyether ether ketone.

Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß mehrere, das Kernelement quer durchsetzende Armierungsteile vorgesehen sind, deren verbreiterte Enden mit den Breitseitenflächen des Kernelements bündig abschließen und mit dem mindestens einen Flachmaterialteil stoffschlüs- sig verbunden, vorzugsweise verklebt sind. Die Armierungsteile weisen zweckmäßig ein Doppel-T-Profil auf und bestehen beispielsweise aus Metall, insbesondere aus Aluminium oder Stahl, oder aus einem faserverstärktem Polymermaterial.A further preferred embodiment of the invention provides that a plurality of reinforcement parts are provided which penetrate the core element, the widened ends of which are flush with the broad side surfaces of the core element and are integrally bonded, preferably glued, to the at least one flat material part. The reinforcement parts expediently have a double-T profile and consist, for example, of metal, in particular of aluminum or steel, or of a fiber-reinforced polymer material.
Bei der Herstellung des Flachmaterialteils wird ein Fasergewebe oder -gelege mit einem Bindemittel getränkt, im Durchlauf aufgeheizt und anschließend wieder abgekühlt und zugleich gepreßt, wobei im Zuge des Herstellungsvorgangs noppenartige Verankerungsteile einseitig angeformt, vorzugsweise aus dem Flachmaterial herausgedrückt werden.In the manufacture of the flat material part, a fiber fabric or scrim is impregnated with a binder, heated in a continuous process and then cooled and pressed again, with knob-like anchoring parts being molded on one side in the course of the manufacturing process, preferably being pressed out of the flat material.
Die erfindungsgemäßen vorgefertigten Bauelemente werden bevorzugt als Wandelemente, Deckenelemente oder Träger für Fertigteilbauwerke verwendet.The prefabricated components according to the invention are preferably used as wall elements, ceiling elements or supports for prefabricated structures.

Die plattenförmigen Bauelemente weisen ein Kernelement aus Beton, Leichtbeton, Gasbeton, Gips auf. Das Kernelement 10 trägt an seinen Breitseitenflächen 20 jeweils ein platten- oder folienförmiges Flachmaterialteil 12 aus faserverstärktem Kunststoff. Bei dem in Fig. 1 gezeigten Ausführungsbeispiel ist das Flachmaterialteil 12 mit einseitig überstehenden noppenartigen Verankerungsorganen 14 in das Kernelement 10 eingegossen und da- mit formschlüssig verankert. Bei dem in Fig. 2 gezeigten Ausführungsbeispiel enthält das Kernelement 10 zusätzlich mehrere, das Kernelement quer durchsetzende Armierungsteile 16, deren verbreiterte Enden 18 mit den Breitseitenflächen 20 des Kernelements 10 bündig abschließen. Die Flachmaterialteile 12 sind in diesem Fall mit Hilfe einer Klebstoffschicht 22 auf die Breitseitenflächen 20 des Kernelements und die Enden 18 der Armierungsteile 16 aufgeklebt. Die ein Doppel-T-Profil aufweisenden Armierungsteile 16 können dabei aus einem Metall, wie Aluminium oder Stahl, oder aus faserverstärktem Polymermaterial bestehen. Im letzeren Falle können die Flachmaterialteile 12 auch auf die Enden 18 der Armierungsteile unter Einwirkung von Druck und Wärme aufgeschweißt werden.The plate-shaped components have a core element made of concrete, lightweight concrete, gas concrete, plaster.

The reinforcing parts 16 having a double-T profile can consist of a metal, such as aluminum or steel, or of fiber-reinforced polymer material. In the latter case, the flat material parts 12 can also be welded onto the ends 18 of the reinforcement parts under the action of pressure and heat.
Die Flachmaterialteile 10 dienen zur Verstärkung des Kernelements und haben die Aufgabe, Zug- und Querkräfte aufzunehmen und ein Ausbrechen von Betonmaterial aus dem Kernelement beim Transport, bei der Montage und bei der Bearbeitung im Fertigzustand zu verhindern. Zusammenfassend ist folgendes festzuhalten: Die Erfindung bezieht sich auf ein vorgefertigtes Bauelement für den Fertigteilbau mit einem Kernelement 10 und mindestens einem Verstärkungsteil 12. Um hohe Zug- und Querkräfte ohne die Gefahr einer Rißbildung aufnehmen zu können, ist das Ver- stärkungsteil als Flachmaterialteil 12 aus faserverstärktem Kunststoff ausgebildet, das an einer Breitseitenfläche 20 des Kernelements 10 form- und/oder stoffschlüssig fixiert ist.
