Description

Die Erfindung betrifft einen Mauerstein aus Porenbeton.The invention relates to a brick made of aerated concrete.

Derartige Mauersteine sind grundsätzlich seit langem bekannt. Sie zeichnen sich durch einen materialeinheitlichen Aufbau aus einem tragenden Betonmaterial aus, dass mit in der Regel feinen Poren innig durchsetzt ist. Durch diese Lufteinschlüsse weist ein solcher Porenbetonstein bereits an sich ein gutes Wärmedämmvermögen auf.Such bricks have basically been known for a long time. They are characterized by a uniform material structure of a load-bearing concrete material that is intimately interspersed with usually fine pores. As a result of these air inclusions, such an aerated concrete block already has per se a good thermal insulation capacity.

An Mauerbaustoffe insbesondere für den Wohnhausbau werden nun zunehmend anspruchsvollere Anforderungen gestellt. So soll die klassische massive Bauweise mit einer hohen Belastbarkeit des Mauerwerks und einem ausgezeichneten Brand- und Lärmschutzverhalten bei möglichst geringen Wanddicken realisierbar sein. Dabei soll eine möglichst hohe Wärmedämmung erreicht werden. Optimaler Weise soll der Wärmedurchgang durch die Wand so niedrig gehalten werden, dass hohe Standards, wie sie beispielsweise für den Bau eines sogenannten Passivhauses gefordert werden, eingehalten sind. Eine schnelle und unkomplizierte Verarbeitung in handwerklich fachgerechter Ausführung soll ferner unterstützt werden. Schließlich soll der Mauerstein baubiologisch unbedenklich sein und eine gute Recycling-Fähigkeit zeigen.Wall construction materials, especially for residential construction, are now becoming increasingly demanding. Thus, the classic solid construction with a high load capacity of the masonry and an excellent fire and noise control behavior with minimum wall thicknesses should be feasible. In this case, the highest possible thermal insulation should be achieved. Optimal way the heat transfer through the wall should be kept so low that high standards, such as those required for the construction of a so-called passive house, are complied with. A quick and uncomplicated processing in technically professional execution should also be supported. Finally, the brick should be biologically harmless and show good recycling ability.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, den klassischen Mauerstein aus Porenbeton ohne besonderen Herstellungsmehraufwand unter Beachtung der vorstehend aufgezeigten Randbedingungen wärmedämmtechnisch zu verbessern.Based on this, the present invention seeks to improve the classic brick of aerated concrete without special manufacturing overhead, taking into account the above-mentioned boundary conditions heat insulation technology.

Diese Aufgabe wird durch einen Porenbeton-Mauerstein mit den im Kennzeichnungsteil des Anspruches 1 angegebenen Merkmalen gelöst.This object is achieved by an aerated concrete brick with the features specified in the characterizing part of claim 1.

Demnach ist eine Zonenaufteilung in Wärmedurchgangsrichtung für den Stein vorgesehen mit

  • einer inneren Tragzone,
  • einer sich daran anschließenden Wärmedämmzone, in der der Mauerstein mit mehreren quer zur Wärmedurchgangsrichtung verlaufenden Reihen vertikaler Dämmbohrungen mit einem Durchmesser von unter 1 cm versehen ist, und
  • einer äußeren Bewitterungszone.
Accordingly, a zoning in heat transfer direction for the stone is provided with
  • an inner support zone,
  • a subsequent thermal insulation zone in which the brick is provided with several transverse to the heat transfer direction rows of vertical Dämmbohrungen with a diameter of less than 1 cm, and
  • an outer weathering zone.

Durch diese Zonenaufteilung, die lediglich durch das einfache Einbringen von Dämmbohrungen in der Wärmedämmzone geschaffen wird, werden die oben erwähnten, teilweise einander widersprechenden Randbedingungen erfüllt. So sorgt die Tragzone für eine ausreichende statische Festigkeit des Mauersteins. Die anschließende Wärmedämmzone verbessert aufgrund der eingebrachten Dämmbohrungen das Dämmverhalten des Steins erheblich. Das Einbringen von Luftkanälen in Mauersteinen ist zwar bereits aus der Ziegelindustrie bekannt, jedoch werden dort relativ grobe und im Wesentlichen gleichmäßig über den Mauerstein in seiner Wärmedurchgangsrichtung verteilte Lochbilder verwendet. Der erfindungsgemäße Mauerstein setzt demgegenüber gezielt in der Wärmedämmzone filigrane, nachträglich einzubringende Bohrungen ein.By this zoning, which is created only by the simple introduction of Dämmbohrungen in the thermal insulation zone, the above-mentioned, partially contradictory boundary conditions are met. Thus, the support zone ensures sufficient static strength of the brick. The subsequent thermal insulation zone improves due to the introduced Dämmbohrungen the insulation behavior of the stone considerably. Although the introduction of air ducts in bricks is already known from the brick industry, but relatively coarse and substantially uniformly distributed over the brick in its heat transfer direction hole patterns are used. In contrast, the brick according to the invention is targeted in the thermal insulation zone filigree, subsequently introduced holes.

Um den Mauerstein auch auf der Außenseite ausreichend, insbesondere gegen Witterungseinflüsse zu schützen, ist die äußere Bewitterungszone vorgesehen.In order to protect the brick well on the outside, in particular against the weather, the outer weathering zone is provided.

Insgesamt bleibt der erfindungsgemäße Mauerstein materialeinheitlich aus Porenbeton, so dass er baubiologisch unbedenklich und gut recycelbar ist. Seine schnelle und unkomplizierte Verarbeitung in handwerklich fachgerechter Ausführung ist problemlos weiterhin möglich.Overall, the brick according to the invention remains the same material of aerated concrete, so that it is biologically harmless and easy to recycle. Its fast and uncomplicated processing in technically professional execution is easily possible.

In den abhängigen Ansprüchen sind bevorzugte Ausführungsformen des Mauersteins angegeben, deren Merkmale, Einzelheiten und Vorteile aus der nachfolgenden Beschreibung von Ausführungsbeispielen anhand der beigefügten Zeichnungen klar werden. Es zeigen:

Letztere sind mittig mit einer vertikal durchgehenden, im Horizontalschnitt halbkreisförmigen Mörtelnut 6 sowie einem nut- und federartigen Passsystem mit im Horizontalschnitt trapezförmigen, vertikal durchgehenden Stegvorsprüngen 7 und korrespondierenden Ausnehmungen 8 versehen.The brick shown in the two drawings consists of conventional aerated concrete and is cuboid in its basic structure with an inner side 1, an outer side 2, (not recognizable) base surface, a top surface 3 and the two lateral joint surfaces 4, 5. The latter are centered with a vertically continuous, in horizontal section semi-circular mortar groove 6 and a nut and spring-like fitting system with trapezoidal in horizontal section, vertically continuous web projections 7 and 8 corresponding recesses provided.

In Wärmedurchgangsrichtung 9 sind eine innere Tragzone 10, eine sich daran anschließende Wärmedämmzone 11 und eine äußere Bewitterungszone 12 vorgesehen.In the heat passage direction 9, an inner support zone 10, an adjoining heat-insulating zone 11 and an outer weathering zone 12 are provided.

Their diameter is on the order of between 5 mm and 10 mm. They are arranged in a row at a uniform grid center distance a R of 10 mm to 20 mm, their center distance a M from row to row being in the same size range.

Bei beiden Ausführungsformen liegen die einzelnen Dämmbohrungen 13 in einer Reihe jeweils mittig versetzt zu den Dämmbohrungen 13 der benachbarten Reihe.In both embodiments, the individual Dämmbohrungen 13 are in a row each centrally offset from the Dämmbohrungen 13 of the adjacent row.
