Description

Technisches GebietTechnical area

Die Erfindung bezieht sich auf ein Verbundelement gemäss dem Oberbegriff des Patentanspruch 1 sowie auf eine Verwendung eines solchen Verbundelementes und auf ein Verfahren zur Herstellung eines solchen Verbundelementes. Derartige Verbundelemente finden Verwendung im Hochbau, insbesondere im Bau von Mehrfamilenhäusern und Geschossbauten beispielsweise für Büros, Gewerbe und Schule.The invention relates to a composite element according to the preamble of claim 1 and to a use of such a composite element and to a method for producing such a composite element. Such composite elements are used in building construction, especially in the construction of multi-family houses and multi-storey buildings, for example, for offices, businesses and schools.

Stand der TechnikState of the art

Es werden heutzutage viele verschiedene Verbundkonstruktionen für Platten im Hochbau eingesetzt. Dabei werden auch Verbünde aus verschiedenen Materialien verwendet, um die jeweiligen Vorteile der beteiligten Materialien zu kombinieren. Beispielsweise sind Verbundelemente bekannt, die konzipiert sind, die Druckfestigkeit von Beton und die Zugfestigkeit von Holz in sich zu vereinen.Today, many different composite structures for slabs are used in building construction. At the same time, composites made of different materials are used to combine the respective advantages of the materials involved. For example, composite elements are known that are designed to be Compressive strength of concrete and the tensile strength of wood to unite.

Eine derartiges Verbundelement ist beispielsweise aus DE 20 2006 015 693 U1 bekannt.Such a composite element is for example made DE 20 2006 015 693 U1 known.

Darstellung der ErfindungPresentation of the invention

Es ist Aufgabe der Erfindung, eine Alternative zu den bekannten Verbundelementen zu schaffen sowie Verwendungen und Verfahren zur Herstellung davon.It is an object of the invention to provide an alternative to the known composite elements and uses and methods for the preparation thereof.

Das Verbundelement weist ein Plattenelement aus Beton und ein dazu parallel angeordnetes Deckelement sowie mindestens ein das Plattenelement mit dem Deckelement verbindendes Trägerelement aus Holz oder Stahl oder Beton auf. Dabei ist das Plattenelement im Zugbereich angeordnet. Dadurch werden verschiedene Verwendungen des Verbundelementes möglich. Beispielsweise kann ein derartiges Verbundelement zur Wärme- und/oder Kältespeicherung und/oder -Reguliergung verwendet werden, wie weiter unten erläutert wird.The composite element has a concrete plate element and a cover element arranged parallel thereto and at least one support element made of wood or steel or concrete connecting the plate element to the cover element. The plate element is arranged in the pulling area. As a result, various uses of the composite element are possible. For example, such a composite element can be used for heat and / or cold storage and / or regulation, as will be explained below.

Beispielsweise weist das Verbundelement mindestens zwei Trägerelemente auf. Diese sind dann beispielsweise parallel zueinander angeordnet. Das Deckelement kann beispielsweise aus Holz und insbesondere eine Holzwerkstoff- oder eine Holzmehrschichtplatte sein. Diverse andere Materialien und Materialkombinationen sind für das Deckelement möglich, beispielsweise zementgebundene Spanplatten, Kunstharzplatten.For example, the composite element has at least two carrier elements. These are then arranged, for example, parallel to each other. The cover element may for example be made of wood and in particular a Holzwerkstoff- or a wood multilayer board. Various other materials and material combinations are possible for the cover element, for example, cement-bonded chipboards, synthetic resin boards.

In einer weiteren Ausführungsform ist das Verbundelement vorfabriziert. Vor einem Einbau des Verbundelementes sind dann also Plattenelement, Deckelement und Trägerelement bereits zu dem Verbundelement zusammengefügt, und es wird zum Beispiel nicht erst nach dem Einbau des Verbundelementes Beton zur Formung des Plattenelementes eingegossen. Das Verbundelement ist bereits vor dem Transport an den Verwendungsort, beispielsweise Baustelle, fertiggestellt. Dadurch ist es möglich, auf dem Verbundelement basierende Konstruktionen innerhalb sehr kurzer Zeit aufzubauen.In a further embodiment, the composite element is prefabricated. Before installation of the composite element then plate element, cover element and support element are already assembled to form the composite element, and it is poured, for example, not only after the installation of the composite element concrete for forming the plate element. The composite element is already finished before being transported to the place of use, for example a construction site. This makes it possible to build on the composite element based structures within a very short time.

In einer weiteren Ausführungsform ist in dem Plattenelement ein Röhrensystem eingebracht. Ein solches Röhrensystem kann nach dem Einbau des Verbundelementes von einem Fluid wie beispielsweise Wasser durchflossen werden und so eine Verwendung des Verbundelementes zum Heizen oder Kühlen eines Raumes verwendet werden. Insbesondere wenn das Verbundelement einen Teil der Decke oder des Daches des Raumes oder Hauses bildet, ist diese Verwendung besonders effizient. Vorteilhaft wird der Grossteil der Decke oder des Daches oder die ganze Decke bzw. das ganze Dach durch mehrere solche Verbundelemente gebildet.In a further embodiment, a tube system is introduced in the plate element. Such a tube system can be traversed by a fluid such as water after installation of the composite element and thus use of the composite element for heating or cooling a room can be used. In particular, when the composite element forms part of the ceiling or the roof of the room or house, this use is particularly efficient. Advantageously, the majority of the ceiling or the roof or the whole ceiling or the whole roof is formed by a plurality of such composite elements.

Entsprechend ist in einer Ausführungsform das Röhrensystem mit einem Fluid befüllbar und weist mindestens einen Einlass und mindestens einen Auslass für das Fluid auf. Decken- oder Bodenheizungen können so realisiert werden. Es ist möglich, die Röhrensysteme verschiedener, insbesondere benachbart eingebauter Verbundelemente miteinander zu verbinden, beispielsweise durch Vorsehen von Verbindungsröhren, die Ein- und Auslasse der verschiedenen Verbundelemente miteinander verbinden, wobei die Verbindungsröhren durch die genannten Ein- und Auslasse selbst gebildet sein können.Accordingly, in one embodiment, the tube system is fillable with a fluid and has at least one inlet and at least one outlet for the fluid. Ceiling or floor heating can be realized in this way. It is possible to connect the tube systems of different, in particular adjacently built composite elements together, for example by providing Connecting tubes that connect the inlet and outlet of the various composite elements together, wherein the connecting tubes can be formed by said inlet and outlet itself.

Beispielsweise weist ein Verbundelement genau einen Einlass und genau einen Auslass oder genau je zwei Ein- und Auslasse auf.For example, a composite element has exactly one inlet and exactly one outlet or exactly two inlets and outlets each.

In einer Ausführungsform weist das Plattenelement eine Bewehrung auf. Dabei kann es sich um eine übliche Bewehrung / Armierung handeln oder auch um Bewehrungsfasern, beispielsweise Stahl-, Kunststoff-, Glas-, oder Kohlefasern. Durch die Bewehrung wird eine erhöhte Zugfestigkeit des Plattenelementes erreicht, und die Bildung von Rissen kann reduziert oder ganz verhindert werden.In one embodiment, the plate element has a reinforcement. This can be a conventional reinforcement / reinforcement or even reinforcing fibers, for example steel, plastic, glass or carbon fibers. By the reinforcement, an increased tensile strength of the plate member is achieved, and the formation of cracks can be reduced or completely prevented.

In einer Ausführungsform besteht zwischen dem Plattenelement und dem Trägerelement eine formschlüssige Schubverbindung. Dadurch kann auf einfache Weise eine unterschiedlich starke Ausdehnung von Plattenelement und Trägerelement in einem Verbundelement aufgenommen werden, ohne dass es beschädigt wird, sei es, dass die unterschiedlich starke Ausdehnung durch mechanische Einwirkung oder durch Temperaturänderung hervorgerufen wird. Das Trägerelement kann dazu ein Profil aufweisen und im Bereich des so profilerten Teiles in dem Plattenelement eingelassen sein, und insbesondere kann das Trägerelement entlang seiner Längserstreckung zwei oder mehr Abschnitte aufweisen, die ein solches Profil aufweisen und in dem Plattenelement eingelassen sind.In one embodiment, there is a positive thrust connection between the plate element and the carrier element. As a result, different degrees of expansion of the plate element and the carrier element in a composite element can be accommodated in a simple manner without it being damaged, be it the fact that the different degrees of expansion are caused by mechanical action or by temperature change. For this purpose, the carrier element can have a profile and be embedded in the plate element in the region of the profiled part, and in particular the carrier element can have along its longitudinal extent two or more sections which have such a profile and are embedded in the plate element.

Beispielsweise ist das Verbundelement ein Boden- und/oder Decken- und/oder Dach- und/oder Wandelement.For example, the composite element is a floor and / or ceiling and / or roof and / or wall element.

Entsprechend besteht eine Verwendung des Verbundelementes in einer Verwendung als Teil einer Gebäudedecke oder eines Gebäudebodens oder eines Gebäudedaches oder einer Gebäudewand oder einer Brückenfahrbahnplatte.Accordingly, there is a use of the composite element in a use as part of a building ceiling or a building floor or a building roof or a building wall or bridge deck slab.

Das Verfahren zur Herstellung eines der beschriebenen Verbundelemente kennzeichnet sich dadurch, dass das Plattenelement erstellt und mit dem Trägerelement verbunden wird bevor das Verbundelement eingebaut wird.The method for producing one of the described composite elements is characterized in that the plate element is created and connected to the carrier element before the composite element is installed.

Weiter kann das Verfahren noch den Schritt aufweisen, dass das mindestens eine Trägerelement mit einem Profil versehen wird, und dass eine Schubverbindung zwischen dem Plattenelement und dem mindestens einen Trägerelement erstellt wird, indem der Beton des Plattenelementes aushärtet während das Trägerelement im Bereich des Profils in dem Beton des Plattenelementes eingebracht ist.Further, the method may further comprise the step of providing the at least one support member with a profile, and creating a thrust connection between the panel member and the at least one support member by curing the concrete of the panel member while the support member is in the region of the profile in the Concrete of the plate element is introduced.
