Description

Die Erfindung betrifft ein Bauelement gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a component according to the preamble of patent claim 1.

Ein Bauelement der eingangs genannten Art ist nach der DE 101 46 755 C1 (siehe insbesondere Absatz [0008]) bekannt. Dieses Bauelement besteht aus einem plattenförmigen, aus einer Vielzahl von Fasern gebildeten, anorganischen Kern und einer mit einer Klebstoffschicht auf einer großen Oberfläche des Kerns befestigte Deckschicht, wobei die Klebetoffschicht anorganisch ausgebildet ist bzw. einen Brennwert PCS kleinergleich 3 MJ/kg aufweist (PCS: Brennwert gemäß DIN EN ISO 1716). Bei dieser Lösung ist die Deckschicht metallisch ausgebildet, d. h. die Formstabilität dieses Bauelements wird durch die Deckschicht gewährleistet. Würde sich diese (zum Beispiel im Brandfall) vom Bauelement lösen, wäre die Verformung bzw. Deformation des verbleibenen Rests aus Kern und Klebstoff vorprogrammiert.A component of the type mentioned is according to the DE 101 46 755 C1 (see in particular paragraph [0008]) known. This device consists of a plate-shaped, formed of a plurality of fibers, inorganic core and attached to an adhesive layer on a large surface of the core cover layer, wherein the adhesive layer is inorganic or has a calorific value PCS equal to 3 MJ / kg (PCS: Calorific value according to DIN EN ISO 1716). In this solution, the cover layer is formed metallic, ie the dimensional stability of this device is ensured by the cover layer. If these were to be detached from the component (for example in the event of a fire), the deformation or deformation of the remainder of the core and adhesive would be preprogrammed.

Der Erfindung liegt die Aufgabe zugrunde, ein Bauelement der eingangs genannten Art zu verbessern. Insbesondere soll ein Bauelement geschaffen werden, dessen Formstabilität auch ohne eine metallische, formsteife Deckschicht gewährleistet ist.The invention has for its object to improve a device of the type mentioned. In particular, a device is to be created whose dimensional stability is ensured even without a metallic, dimensionally stable cover layer.

Diese Aufgabe ist nach der Erfindung mit einem Bauelement der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.This object is achieved according to the invention with a component of the type mentioned by the features listed in the characterizing part of patent claim 1.

Nach der Erfindung ist also vorgesehen, dass die Klebstoffschicht eine größere Steifigkeit als die Deckschicht aufweist.According to the invention, it is thus provided that the adhesive layer has a greater rigidity than the cover layer.

Mit anderen Worten besteht die Erfindung darin, die Formstabilität des Bauelements durch eine entsprechend stark ausgebildete Klebstoffschicht zu gewährleisten. Dabei ist zu beachten, dass ein im wesentlichen anorganischer Klebstoff, wie zum Beispiel Fliesenkleber, Estrich, Mörtel oder dergleichen, nach dem Abbinden bzw. Trocknen bei entsprechender Dicke eine form- und druckstabile Schicht bildet und die Deckschicht dementsprechend dünn und aus einem vergleichweise nachgiebigen Material ausgebildet sein kann.In other words, the invention is to ensure the dimensional stability of the device by a correspondingly strong adhesive layer. It should be noted, a substantially inorganic adhesive, such as, for example, tile adhesive, screed, mortar or the like, forms a dimensionally stable and pressure-stable layer after setting or drying, and the cover layer can accordingly be made thin and of a comparatively compliant material.

Unter "Steifigkeit" ist dabei der Widerstand der Klebstoff- bzw. Deckschicht gegen Verformung durch eine von außen wirkende Kraft zu verstehen. Da es sich in beiden Fällen um Schichten handelt, ist im vorliegenden Fall insbesondere die Biegesteifigkeit von Bedeutung. Aber auch die Dehnsteifigkeit (zum Beispiel bei punktueller Druckbelastung) und die Torsionssteifigkeit (bei einer Drehkraftbelastung) sind von der erfindungsgemäßen Maßgabe gemäß Patentanspruch 1 umfasst, wobei stets von der Steifigkeit der jeweiligen Schicht insgesamt auszugehen ist, also sowohl deren werkstoff als auch deren Geometrie zu berücksichtigen ist.By "stiffness" is meant the resistance of the adhesive or cover layer against deformation due to an external force. Since both layers are layers, the bending stiffness is of particular importance in the present case. But also the Dehnsteifigkeit (for example at punctual pressure load) and the torsional stiffness (at a torque load) are encompassed by the proviso according to the invention according to claim 1, which is always based on the stiffness of the respective layer in total, so both their material and their geometry take into account.

Andere vorteilhafte Weiterbildungen des erfindungsgemäßen Bauelements ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the device according to the invention will be apparent from the dependent claims.

Das erfindungsgemäße, als Baustoffplatte ausgebildete Bauelement einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung einer bevorzugten Ausführungsform näher erläutert.The inventive component formed as a building material plate including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of a preferred embodiment.

It shows schematically
FIG. 1
in section the inventive, provided on both sides with a cover layer and designed as Wandbaupaneel device.

Das in Figur 1 dargestellte Bauelement besteht aus einem plattenförmigen, aus einer Vielzahl von Fasern gebildeten Kern 1, wobei zum Verbund der Fasern (wie üblich) ein entsprechend geeignetes Bindemittel oder dergleichen vorgesehen ist bzw. sein kann und wobei der Kern mindestens die Kriterien gemäß Baustoffklasse A2 nach EN 13501-1 erfüllt, also nicht brennbar ist. Weiterhin besteht das Bauelement aus einer mit einer Klebstoffchicht 2 (zum Beispiel Zement, Fliesenkleber, Mörtel Estrich oder dergleichen) auf einer großen Oberfläche des Kerns 1 befestigten Deckschicht 3, wobei die Klebstoffschicht 2 im wesentlichen anorganisch ausgebildet ist bzw. einen Brennwert PCS kleinergleich 3 MJ/kg aufweist (also ebenfalls die Kriterien der Baustoffklasse A2 gemäß EN 13501-1 erfüllt).This in FIG. 1 shown component consists of a plate-shaped, formed from a plurality of fibers core 1, wherein the composite of the fibers (as usual) is provided or can be a suitably suitable binder or the like and wherein the core at least the criteria according to building material class A2 according to EN 13501 -1 is met, so it is not flammable. Furthermore, the device consists of a covering layer 3 fastened to a large surface of the core 1 with an adhesive layer 2 (for example cement, tile adhesive, mortar screed or the like), the adhesive layer 2 being substantially inorganic or having a calorific value PCS of at least 3 MJ / kg (ie also meets the criteria of building material class A2 according to EN 13501-1).

Unter "plattenförmig" ist dabei eine Körperform zu verstehen, die zwei große, parallel zueinander verlaufende Oberflächen und dazu (im wesentlichen) senkrecht stehende, die Oberflächen miteinander verbindende Stirnseiten aufweist.The term "plate-shaped" is to be understood as meaning a body shape which has two large, mutually parallel surfaces and (substantially) vertical end faces which connect the surfaces to one another.

Damit das erfindungsgemäße Bauelement allseitig optisch ansprechend aussieht und eine gute Handhabbarkeit aufweist, ist vorgesehen. dass der plattenförmige Kern 1 auf beiden seiner großen Oberflächen mit einer Klebstoffschicht 2 (als Zwischenlage und jeweils mit einem Brennwert PCS kleinergleich 3 MJ/kg) und einer Deckschicht 3 versehen ist und dass Schmalseiten des plattenförmigen Kerns 1 einschließlich der Klebstoffschicht 2 und der Deckschicht 3 mit einer (vorzugsweise aufgeklebten und ebenfalls nicht brennbaren) Kantenabdeckung 5 versehen sind.So that the device according to the invention looks attractive on all sides and has a good handling, is provided. that the plate-shaped core 1 is provided on both its large surfaces with an adhesive layer 2 (as intermediate layer and each with a calorific value PCS 3 MJ / kg smaller) and a cover layer 3 and that narrow sides of the plate-shaped core 1 including the adhesive layer 2 and the cover layer 3rd are provided with a (preferably glued and also non-flammable) edge cover 5.

Ein solches, als Baustoffplatte ausgebildetes Bauelement dient erfindungsgemäß insbesondere und bevorzugt als Wand- oder Deckenbaupaneel im Sinne eines Raumabschlusses oder eines Gehäuses. In Figur 1 ist dabei ein Wandbaupaneel dargestellt, das zwischen einem bodenseitigen und einem deckenseitigen, u-förmigen Profil 6 angeordnet ist, wobei die vorzugsweise metallischen Profile 6 direkt (zum Beispiel per Verschraubung) am Boden bzw. an der Decke eines Gebäudes befestigt sind. Alternativ (nicht dargestellt), kann aber auch vorgesehen sein, dass das deckenseitige Profil am Rahmen einer abgehängten Rasterdecke angeordnet ist. Um einzelnen Bauelemente miteinander zu verbinden, sind zwischen den Wandbaupaneelen vertikal orientierte, H-förmige Verbindungsprofile angeordnet.Such, designed as a building material component component used according to the invention in particular and preferably as a wall or ceiling panel in the sense of a room closure or a housing. In FIG. 1 In this case, a Wandbaupaneel is shown, between a bottom-side and a ceiling-side, U-shaped Profile 6 is arranged, wherein the preferably metallic profiles 6 are attached directly (for example by screwing) on the floor or on the ceiling of a building. Alternatively (not shown), but can also be provided that the ceiling-side profile is arranged on the frame of a suspended grid ceiling. To connect individual components together, vertically oriented, H-shaped connection profiles are arranged between the wall panels.

Besonders wesentlich für das erfindungsgemäße Bauelement ist nun, dass die Klebstoffschicht 2 eine größere Steifigkeit als die Deckschicht 3 aufweist.It is particularly important for the component according to the invention that the adhesive layer 2 has a greater rigidity than the cover layer 3.

Wie bereits eingangs erläutert, hat diese Maßgabe zur Folge, dass die Formstabilität des Bauelements im wesentlichen durch die Klebeschicht 2 selbst und nicht etwa durch die Deckschicht 3 gewährleistet wird. Hierzu wird erfindungsgemäß eine Klebstoffschicht 2 verwendet, die im abgebundenen Zustand mehr als 1 kg/m2 wiegt oder mindestens 1 mm dick ausgebildet ist.As already explained at the outset, this proviso has the consequence that the dimensional stability of the component is essentially ensured by the adhesive layer 2 itself and not by the cover layer 3. For this purpose, an adhesive layer 2 is used according to the invention, which weighs more than 1 kg / m 2 in the set condition or is at least 1 mm thick.

Dabei ist, wie aus Figur 1 ersichtlich, besonders bevorzugt vorgesehen, dass eine Vielzahl von freien Ende der Fasern des Kerns 1 im wesentlichen senkrecht in der Klebstoffschicht 2 ausmündend ausgebildet sind. Mit anderen Worten sind die Fasern des Kerns 1 so ausgerichtet angeordnet, dass sie im rechten Winkel zur Hauptebene der Klebstoffschicht 2 verlaufen und mit ihren Faserspitzen in dieser eingebettet sind, so dass das erfindungsgemäße Bauelement nicht nur insgesamt formstabil ist, sondern darüber hinaus bei einer Flächenbelastung eine hohe Druckstabilität aufweist.It is how out FIG. 1 can be seen, particularly preferably provided that a plurality of free ends of the fibers of the core 1 are formed opening substantially perpendicular in the adhesive layer 2. In other words, the fibers of the core 1 are arranged aligned so that they extend at right angles to the main plane of the adhesive layer 2 and are embedded with their fiber tips in this, so that the device according to the invention is not only dimensionally stable, but also in a surface load has a high pressure stability.

Bezüglich des Kerns 1 ist vorgesehen, dass dieser wahlweise im wesentlichen aus mineralischen und/oder keramischen, also anorganischen Fasern gebildet ist. Das verwendete Fasermaterial weist dabei vorzugsweise ein spezifisches Gewicht von 50 bis 300 kg/m3 auf, wobei der Kern 1 selbst vorzugsweise zwischen 20 und 150 mm dick ausgebildet ist.With regard to the core 1, it is provided that it is optionally formed essentially of mineral and / or ceramic, ie inorganic fibers. The fiber material used preferably has a specific weight of 50 to 300 kg / m 3 , wherein the core 1 itself is preferably formed between 20 and 150 mm thick.

Da die Deckschicht 3 beim dargestellten Bauelement für die Form- und Druckstabilität von untergeordneter Bedeutung ist, weist diese gemäß der Erfindung lediglich eine Dicke zwischen 0,01 und 0,3 mm auf. Sie besteht wahlweise aus einem Schicht-stoff (mehreren in Phenolharz getränkten Papierschichten, die unter Hochdruck zusammengefügt werden), Kunststoff, einem Holzwerkstoff (Echtholzfunier), CPL (Continuous Pressing Laminates), HPL (High Pressure Laminate) oder dergleichen.Since the cover layer 3 is of subordinate importance in the illustrated structural and pressure stability component, according to the invention it only has a thickness between 0.01 and 0.3 mm. It consists either of a layered material (several phenolic resin impregnated paper layers which are joined together under high pressure), plastic, a wood material (real wood veneer), CPL (Continuous Pressing Laminates), HPL (High Pressure Laminate) or the like.

Je nach Festlegung der eingesetzten Materialien (nicht brennbarer Kern und nicht brennbarer Klebstoff) und Materialstärken kann das erfindungsgemäße Bauelement einen den Brandschutznormen entsprechenden Feuerwiderstand aufweisen. Bei einer vergleichsweise dünn ausgelegten Deckschicht 3 kann diese sogar brennbar (im Sinne der DIN 4102 Teil 1) sein, ohne dass dadurch der Feuerwiderstand des Gesamtbauteils in Frage gestellt ist. Weiterhin liegt es auch, wie bereits durch die Angabe des Brennwerts PCS angedeutet, im Rahmen der Erfindung, dass in die an sich anorganische Klebstoffschicht 2 Anteile von organischem Klebstoff eingebracht sind, da diese sich zum Beispiel positiv auf das Fließverhalten des Klebstoffs auswirken, aber in bestimmten Grenzen den Feuerwiderstand des Gesamtbauteils nicht beeinträchtigen.Depending on the specification of the materials used (non-combustible core and non-combustible adhesive) and material thicknesses, the component according to the invention may have a fire resistance corresponding to the fire protection standards. In the case of a comparatively thin cover layer 3, it can even be combustible (within the meaning of DIN 4102 Part 1), without the fire resistance of the entire component being called into question. Furthermore, it is also, as already indicated by the indication of the calorific value PCS, within the scope of the invention that 2 parts of organic adhesive are introduced into the inorganic adhesive layer 2, since these have a positive effect on the flow behavior of the adhesive, for example certain limits do not affect the fire resistance of the entire component.

Weiterhin ist besonders bevorzugt vorgesehen und in Figur 1 dargestellt, dass die Klebstoffschicht 2 und die Deckschicht 3 zur Ausbildung einer schalldämmenden Baustoffplatte mit Durchgangsöffnungen 4 versehen sind. Diese sind dabei bevorzugt in einem klebstofffreien Bereich des aus Fasern gebildeten Kerns 1 ausmündend ausgebildet, so dass sich über die Durchgangsöffnungen 4 eindringender Schall im Faserkern des Bauelements "verläuft". Hierzu weisen sie vorzugsweise einen Durchmesser von 0,1 bis 5 mm auf und sind zum Beispiel per Laserstrahl in die Deckschicht 3 und die Klebstoffschicht 2 eingebracht ausgebildet.Furthermore, it is particularly preferred and provided in FIG. 1 illustrated that the adhesive layer 2 and the cover layer 3 are provided to form a sound-insulating building material plate with through holes 4. These are preferably formed opening out in an adhesive-free region of the core 1 formed of fibers, so that over the passage openings 4 penetrating sound in the fiber core of the device "runs". For this purpose, they preferably have a diameter of 0.1 to 5 mm and are formed, for example, introduced by laser beam into the cover layer 3 and the adhesive layer 2.

Die Herstellung des erfindungsgemäßen Bauelements erfolgt dadurch, dass eine vorzugsweise in eine entsprechende Form eingelegte Deckschicht 3 mit einer (im wesentlichen) anorganischen Klebstoffschicht 2 versehen und der Kern 1 in die fließfähige. Klebstoffschicht 2 getaucht bzw. eingelegt und vorzugsweise unter Druck in dieser Position bis zum Abbinden der Klebstoffschicht 2 gehalten wird, wobei eine entsprechende zweite Oberflächenschicht auf der Rückseite des Kerns 1 wahlweise gleichzeitig oder später aufgebracht werden kann.The component according to the invention is produced by providing a cover layer 3, which is preferably inserted in a corresponding shape, with a (substantially) inorganic adhesive layer 2 and the core 1 into the flowable layer. Adhesive layer 2 dipped or inserted and is preferably held under pressure in this position until setting of the adhesive layer 2, wherein a corresponding second surface layer on the back of the core 1 can be applied either simultaneously or later.

Gemäß eines besonders bevorzugten Verfahrens zur Herstellung einer schalldämmenden Baustoffplatte ist vorgesehen, dass bei Verwendung einer gelochten Deckschicht 3 im Bereich der Durchgangsöffnungen ein Klebstofferstarrungsverzögerer (wie er zum Beispiel bei der Herstellung von Waschbetonplatten verwendet wird) aufgebracht (besonders bevorzugt in Form einer entsprechend lokal präparierten Folie, die vor dem Einbringen des Klebstoffs zwischen die oben genannte Form und die Deckschicht 3 gelegt wird) und die noch nicht abgebundene Klebstoffschicht 2 in diesem Bereich nach Erstarren der übrigen Klebstoffschicht 2 entfernt (bzw. durchstoßen) wird.According to a particularly preferred method for producing a sound-absorbing building material panel is provided that when using a perforated cover layer 3 in the region of the through holes an adhesive retardant (as used for example in the production of washed concrete slabs) applied (particularly preferably in the form of a correspondingly locally prepared film , which is placed between the above-mentioned mold and the cover layer 3 before the introduction of the adhesive) and the not yet set adhesive layer 2 in this area after solidification of the remaining adhesive layer 2 is removed (pierced).
