Deckenplatte eingesetzt werden kann.The invention relates to a load-bearing and heat-insulating brick (1), which can be used for effective heat dissipation between a wall and a floor or floor slab.
Bauelemente, die für eine vergleichbare Verwendung vorgesehen sind, werden beispielsweise in dem deutschen Gebrauchsmuster
Der Nachteil dieser Ausführung ist darin zu sehen, dass die Stege die wärmedämmenden Eigenschaften des Mauersteins sowohl in vertikaler als auch in horizontaler Richtung negativ beeinflussen. Außerdem macht diese komplizierte Konfiguration die Herstellung unverhältnismäßig aufwendig und teuer.The disadvantage of this embodiment is the fact that the webs adversely affect the thermal insulation properties of the brick both in the vertical and in the horizontal direction. In addition, this complicated configuration makes the production disproportionately expensive and expensive.

Nachteilig an diesem schon seit vielen Jahren bekannten Bauelement ist die viel zu geringe Wärmeentkopplung in Verbindung mit aus heutiger Sicht nicht mehr vertretbaren Herstellungskosten.A disadvantage of this already known for many years device is the much too low heat dissipation in connection with no longer justifiable from today's perspective manufacturing costs.
Im gleichen Maße aus der
Die der vorliegenden Erfindung zugrunde liegende Aufgabe soll in der Entwicklung eines wärmedämmenden Mauersteins liegen, der insbesondere die genannten Nachteile der aus dem gewürdigten Stand der Technik bekannten Bauelemente überwindet, in seiner Herstellung wesentlich vereinfacht ist und dabei die Wärmedämmung signifikant verbessert.The object underlying the present invention is to be in the development of a heat-insulating brick, which overcomes in particular the mentioned disadvantages of known from the acknowledged state of the art components, in its production is substantially simplified and thereby significantly improves the thermal insulation.
Der Erfinder erkannte ferner, dass ein in der heutigen Zeit überzeugender Mauerstein nicht nur zur effektiven Wärmeentkopplung zwischen einer Mauerwand und einer Boden- bzw. Deckenplatte einzusetzen sein muss, sondern auch als Mauerstein für den Aufbau tragender und nichttragender Wände geeignet sein soll.The inventor further recognized that in today's time compelling bricks must not only be used for effective heat dissipation between a wall and a floor or floor slab, but should also be suitable as a brick for the construction of load-bearing and non-load-bearing walls.
Diese Aufgabe wird erfindungsgemäß mit einem wärmedämmenden Mauerstein (1) gelöst, umfassend
- einen durch zwei sich gegenüberliegende Auflageflächen begrenzten Wärmedämmkörper (2),
- zwei einzelne Beschichtungen (5), von denen jeweils eine mit einer der beiden Auflageflächen fest verbunden ist,
- durch den Wärmedämmkörper (2) verlaufende Stützorgane,
- a heat-insulating body (2) delimited by two opposite bearing surfaces,
- two individual coatings (5), one of which is firmly connected to one of the two bearing surfaces,
- by the heat-insulating body (2) extending supportive organs,
Ein solcher Mauerstein ist geeignet zur Herstellung einer Wärmeentkopplung zwischen Wand und Boden bzw. Wand und Decke als auch zum Bau von Mauerwerken und löst damit die der Erfindung zugrunde liegende Aufgabe.Such a brick is suitable for producing a heat decoupling between wall and floor or wall and ceiling as well as for the construction of masonry and thus solves the problem underlying the invention.
Der erfindungsgemäße Mauerstein (1) umfasst somit einen Mineral- oder Kunststoffschaumkörper als Wärmedämmkörper (2), zwischen dessen Auflageflächen sich in Lastrichtung Tragsäulen (4) befinden, deren Form, Abmessung, Anzahl und Position in Abhängigkeit von der erforderlichen und/oder gewünschten Belastbarkeit festgelegt werden. Bevorzugt sind Tragsäulen (4) mit rundem oder drei-, vier- bzw. fünfeckigen Horizontalquerschnitt, doch auch eine Kombination der genannten Querschnittsformen sind vorstellbar. Besonders gute Ergebnisse konnten mit runden Tragsäulen (4) erzielt werden, die einen Durchmesser (d) in einem Bereich von 22 mm bis 32 mm aufweisen bei einem jeweiligen Achsenabstand der Tragsäulen (4) von (s). Dabei erfüllt (s) bevorzugt die Bedingung (s) = f • (d), mit f liegt in einem Bereich zwischen 2 und 3.The brick according to the invention (1) thus comprises a mineral or plastic foam body as a heat insulation body (2), between the bearing surfaces are in the load direction support columns (4) whose shape, size, number and position determined depending on the required and / or desired load capacity become. Preferred are support columns (4) with round or triangular, four- or pentagonal horizontal cross-section, but also a combination of said cross-sectional shapes are conceivable. Particularly good results could be achieved with round support columns (4) having a diameter (d) in a range of 22 mm to 32 mm at a respective axis spacing of the support columns (4) of (s). In this case, the condition (s) preferably satisfies (s) = f (d), with f lying in a range between 2 and 3.
Die vertikalen Tragsäulen (4) sind durch die tragenden, bevorzugt armierten Beschichtungen (5) auf der oberen und auf der unteren Auflagefläche fest miteinander verbunden und auf diese Art sowohl vertikal als auch horizontal fixiert. Die tragenden, bevorzugt bewehrten Beschichtungen (5), die sich auf den Auflageflächen befinden, spielen eine große Rolle für die Stabilität des gesamten erfindungsgemäßen Mauersteins (1), insbesondere für die Erhöhung der Biege- und weiterer mechanischer Festigkeiten bei gleichzeitiger Verbesserung der Resistenz gegenüber einwirkenden Kräften. Für die einzelne tragende Beschichtung (5) eignet sich - in Abhängigkeit von der gewünschten Anwendung - unter anderem ein Zementmörtel, eine Polymermasse oder eine geeignete Mischung beider Systeme, beispielsweise ein Polymermörtel, besonders bevorzugt mit einer eingebetteten oder eingemischten Armierung, wie z.B. Glasgittergewebe, Vlies, Fasern oder ähnliches. Von großem Vorteil bei der Wahl des Beschichtungsmaterials ist es, wenn das Beschichtungsmaterial möglichst wasserdicht bzw. wasserabweisend ist.The vertical support columns (4) are fixedly connected to one another by the load-bearing, preferably reinforced coatings (5) on the upper and on the lower support surface and in this way are fixed both vertically and horizontally. The bearing, preferably reinforced coatings (5), which are located on the support surfaces, play a major role in the stability of the entire wall block (1) according to the invention, in particular for increasing the bending and other mechanical strengths while improving the resistance to acting forces. For the individual load-bearing coating (5), depending on the desired application, a cement mortar, a polymer mass or a suitable mixture of both systems is suitable, for example a polymer mortar, more preferably with an embedded or mixed reinforcement, e.g. Glass mesh fabric, nonwoven, fibers or the like. Of great advantage in the choice of the coating material is when the coating material is as waterproof as possible or water-repellent.
In einer bevorzugten Ausführungsform besteht der erfindungsgemäße Mauerstein (1) ausschließlich aus dem Wärmedämmkörper (2), aus den diesen Wärmedämmkörper (2) in vertikaler Richtung durchlaufenden Tragsäulen (4) und aus je einer Beschichtung (5) oberhalb und unterhalb des Wärmedämmkörpers (2). Weil die bevorzugt mit einer Armierung versehenen Beschichtungen (5) für die Stabilität des erfindungsgemäßen Mauersteins (1) so bedeutsam sind, ist es wesentlich, wenn die Beschichtungen (5) unlöslich mit den Tragsäulen (4) und gegebenenfalls zusätzlich mit dem Wärmedämmkörper (2) verbunden sind. Diese Verbindung kann durch Verkleben, Verkerben, Verschmelzen oder durch Angießen des Materials entweder für die Tragsäulen (4) oder für die Beschichtungen (5) an den jeweils bereits fertig gestellten Gegenpart aus Tragsäulen (4) und Beschichtungen (5) umgesetzt werden, ohne darauf beschränkt zu sein.In a preferred embodiment, the brick (1) according to the invention consists exclusively of the heat-insulating body (2), of the heat-insulating body (2) passing through in the vertical direction of support columns (4) and of a respective coating (5) above and below the heat-insulating body (2). , Because the coatings (5) preferably provided with a reinforcement are so important for the stability of the brick (1) according to the invention, it is essential if the coatings (5) are insoluble with the support columns (4) and optionally additionally with the heat insulation body (2). are connected. This compound can be implemented by gluing, scoring, fusing or by casting the material either for the support columns (4) or for the coatings (5) to the respective already completed counterpart of support columns (4) and coatings (5) without it to be limited.
Eine zusätzliche, wasser- und/oder kapillardichte Beaufschlagung der einzelnen Beschichtung (5) ist denkbar und stellt im Sinne der vorliegenden Erfindung eine ganz besonders bevorzugte Ausführungsform dar. Dabei geschieht die Beaufschlagung beispielsweise mittels einer bituminösen oder polymeren Beaufschlagungsmasse.An additional, water and / or capillary-tight loading of the individual coating (5) is conceivable and in the context of the present invention, a very particularly preferred embodiment. The admission is done for example by means of a bituminous or polymeric Beaufschlagungsmasse.
Auf den zwei sich gegenüberliegenden, den Wärmedämmkörper (2) begrenzenden Auflageflächen ist jeweils eine tragende, bevorzugt armierte Beschichtung (5) unlöslich und bevorzugt vollflächig aufgebracht. Alternativ ist auch eine unterbrochen ausgeführte Beschichtung (5) denkbar. Diese unterbrochene Beschichtung (5) kann in Form zufälliger und/oder gezielt gestalteter Muster ausgeführt sein.On the two opposite, the heat-insulating body (2) limiting bearing surfaces each a supporting, preferably reinforced coating (5) is insoluble and preferably applied over the entire surface. Alternatively, an interrupted running coating (5) is conceivable. This interrupted coating (5) can be designed in the form of random and / or deliberately designed patterns.
Gewöhnlich wird die einzelne Beschichtung (5) direkt auf die jeweilige Auflagefläche und die oberen bzw. unteren Enden der Tragsäulen (4) aufgetragen, das bedeutet, dass das zunächst noch flüssige oder pastöse Material zur Ausbildung der einzelnen Beschichtungen (5) auf die jeweilige Auflagefläche und die oberen bzw. unteren Enden der Tragsäulen (4) aufgespritzt, aufgeschmiert bzw. aufgeschüttet und danach getrocknet bzw. gehärtet wird. Eine zusätzliche Verschraubung, Verkerbung, Verschmelzung oder sonstige zusätzliche Verstärkung der Verbindung von den Beschichtungen (5) mit den Tragsäulen (4) ist möglich. Die Beschichtungen (5) können aber auch separat gefertigt und mit einem geeigneten Klebstoff auf die oberen bzw. unteren Enden der Tragsäulen (4) und bevorzugt zusätzlich auf die Auflageflächen aufgeklebt werden. Ebenfalls denkbar und bevorzugt im Sinne der vorliegenden Erfindung ist die Fertigung einer Haftschutzbeschichtung (6) für die seitlichen Oberflächen des erfindungsgemäßen Mauersteins (1). Die Aufrauung oder Strukturierung der Oberflächen von Beschichtung (5) und/oder Haftschutzbeschichtung (6) beispielsweise durch Aufbringen von Quarzsand oder Splitt geeigneter Körnung in die frische (nasse) Beschichtungsmasse verbessert die Haftung von Mörtel oder Kleber auf der jeweiligen Beschichtung (5, 6).Usually, the individual coating (5) is applied directly to the respective support surface and the upper or lower ends of the support columns (4), which means that the initially liquid or pasty material for forming the individual coatings (5) on the respective support surface and the upper and lower ends of the support columns (4) is sprayed, lubricated and then dried or hardened. An additional screwing, staking, merging or other additional reinforcement of the compound of the coatings (5) with the support columns (4) is possible. However, the coatings (5) can also be manufactured separately and adhered with a suitable adhesive to the upper or lower ends of the support columns (4) and preferably additionally to the bearing surfaces. Also conceivable and preferred for the purposes of the present invention is the production of an adhesion protection coating (6) for the lateral surfaces of the brick (1) according to the invention. The roughening or structuring of the surfaces of coating (5) and / or protective coating (6), for example, by applying quartz sand or grit of suitable grain size in the fresh (wet) coating composition improves the adhesion of mortar or adhesive on the respective coating (5, 6) ,
Der Wärmedämmkörper (2), durch den die Tragsäulen (4) verlaufen, besteht bevorzugt aus Kunststoffschaum, wie z.B. (extrudiertem) Polystyrol-, PU-, PVC, Phenol- oder Mineralschaum, wie z.B. Glas- oder Steinschaum. Für die Wahl des Wärmedämmmaterials sind hauptsächlich ein niedriger Wärmedämmkoeffizient und eine möglichst geringe Wasseraufnahme ausschlaggebend, da die Tragsäulen (4) und die mit ihnen verbundene armierte Beschichtung (5) die einwirkenden Kräfte aufnehmen.The heat-insulating body (2), through which the support columns (4) extend, is preferably made of plastic foam, such as e.g. (extruded) polystyrene, PU, PVC, phenolic or mineral foam, e.g. Glass or stone foam. For the choice of thermal insulation material mainly a low thermal insulation coefficient and the lowest possible water absorption are crucial, since the support columns (4) and their associated reinforced coating (5) absorb the forces acting.
In zahlreichen Untersuchungen zeigte sich, dass der erfindungsgemäße Mauerstein (1) bevorzugt eine flache, breite Bauform aufweist, weil hier die Verwendung besonders einfach und die Wärmedämmung besonders effizient sind. So sind Maße von 40 mm bis 60 mm Höhe, Längen von 450 mm bis 550 mm und Breiten von 80 mm bis 240 mm bevorzugt.Numerous studies have shown that the brick according to the invention (1) preferably has a flat, wide design, because here the use is particularly simple and the thermal insulation is particularly efficient. Thus, dimensions of 40 mm to 60 mm in height, lengths of 450 mm to 550 mm and widths of 80 mm to 240 mm are preferred.
Zur Herstellung des erfindungsgemäßen Mauersteins (1) wird sein noch nicht mit den Beschichtungen (5) versehener Wärmedämmkörper (2) in definierten Abständen mit vertikalen Durchbrüchen (3), vorzugsweise mit Löchern, geeigneter Abmessungen über die gesamte Dicke versehen. Diese Durchbrüche (3) werden anschließend mit einem geeigneten Material zur Herstellung der Tragsäulen (4) ausgefüllt. Dabei ist es bevorzugt, wenn das zunächst flüssige oder pastöse Material für die Tragsäulen (4) in die Durchbrüche (3) des Wärmedämmkörpers (2) eingegeben wird, wo daraufhin dieses Material trocknet und/oder aushärtet und so die festen Tragsäulen (4) ausbildet. Es ist auch denkbar, dass die Tragsäulen (4) separat gefertigt und dann in die Löcher (3) eingeschoben und mit dem Wärmedämmkörper (2) verklebt bzw. verschmolzen werden.For the production of the brick (1) according to the invention is not yet provided with the coatings (5) heat insulation body (2) at defined intervals with vertical openings (3), preferably provided with holes of suitable dimensions over the entire thickness. These breakthroughs (3) are then filled with a suitable material for the preparation of the support columns (4). It is preferred if the initially liquid or pasty material for the support columns (4) in the openings (3) of the heat-insulating body (2) is entered, where then this material dries and / or hardens and so the solid support columns (4) is formed , It is also conceivable that the support columns (4) manufactured separately and then inserted into the holes (3) and glued or fused with the heat-insulating body (2).
Das Tragsäulenmaterial selbst besteht aus einem Mörtel, der unter Verwendung eines hydraulischen Bindemittels, wie beispielsweise Zement oder Gips oder eines Polymerbindemittels, wie beispielsweise Epoxid-, PU-, Acrylat- oder Polyesterharz sowie einem oder mehreren Füllstoffen- und Zuschlagstoffen mit oder ohne Zugabe von Fasern, Vlies oder Gewebe hergestellt ist.The support column material itself consists of a mortar made using a hydraulic binder such as cement or gypsum or a polymer binder such as epoxy, PU, acrylate or polyester resin and one or more fillers and aggregates with or without the addition of fibers , Fleece or fabric is made.
Die Druckfestigkeit der Tragsäulen (4) liegt zwischen 10 und 80 N/mm2 und die Wärmeleitfähigkeit zwischen 0,1 und 1,0 W/mK. Höhere mechanische Festigkeiten sind im Allgemeinen mit schlechteren Wärmedämmeigenschaften verbunden, was durch die Wahl des Bindemittels, der Zuschlagstoffe und der Mischungsverhältnisse zu steuern ist.The compressive strength of the support columns (4) is between 10 and 80 N / mm2 and the thermal conductivity between 0.1 and 1.0 W / mK. Higher mechanical strengths are generally associated with poorer thermal insulation properties, which can be controlled by the choice of binder, aggregates and mixing ratios.
Die Wahl des Tragsäulenmaterials und deren Flächenanteil richtet sich nach den für die vorgesehene Anwendung erforderlichen mechanischen Festigkeiten. Vorteilhaft ist die Wahl von Materialien, die den mechanischen Erfordernissen gerecht werden und gleichzeitig einen möglichst niedrigen Wärmedämmkoeffizient aufweisen.The choice of the support column material and their area ratio depends on the mechanical strength required for the intended application. Advantageous is the choice of materials that meet the mechanical requirements and at the same time have the lowest possible thermal insulation coefficient.
