Description

Die Erfindung betrifft eine Betonfertigschichtplatte, ein Verfahren zur Herstellung derselben und ein Verfahren zur Entsorgung von Dämmstoff.The invention relates to a precast concrete slab, a method for producing the same and a method for disposing of insulating material.

Betonfertigplatten sind bekannt, um Industriebauwerke herzustellen. DE-U-20 2010 017 363 beschreibt eine Kellerwand aus zwei Betonplatten, die mittels Abstandhalter aus einem Gitterwerk, zwischen den Betonplatten einen Hohlraum bilden, der mit Wärmedämmschüttung aufgefüllt werden kann, wobei das Gitterwerk korrosiv ist und eine Wärmebrücke darstellt, so dass die Wärmedämmwerte im Inneren der Kellerwand erniedrigt sind, wobei die Betonplatten an ihrer Aufstellfläche eine Fuge (zwischen Betonfertigteil und Bodenfläche) aufweist, die mit Mörtel ausgefüllt ist.Precast concrete panels are known to produce industrial buildings. DE-U-20 2010 017 363 describes a basement wall made of two concrete slabs, which by means of spacers from a latticework, form a cavity between the concrete slabs, which can be filled with thermal insulation filler, whereby the latticework is corrosive and represents a thermal bridge, so that the thermal insulation values inside the basement wall are lowered, whereby the concrete slabs have a joint on their installation surface (between the precast concrete part and the floor surface) which is filled with mortar.

In EP 0 756 045 A1 beschreibt eine selbsttragende Bautafel zur Errichtung eines schrägen Daches die einen durch zwei Betonplatten gebildeten, definiertem Hohlraum aufweist, der durch ein Gitterwerk im Inneren gebildet wird, was korrosiv ist und eine Wärmebrücke darstellt, so dass die Wärmedämmwerte im Inneren der Kellerwand niedrig sind, wobei der Hohlraum zur Aufnahme einer wärmedämmenden Füllung, geeignet ist.In EP 0 756 045 A1 describes a self-supporting construction panel for the erection of a sloping roof which has a defined cavity formed by two concrete slabs, which is formed by a latticework inside, which is corrosive and represents a thermal bridge, so that the thermal insulation values inside the basement wall are low Cavity for receiving a heat insulating filling, is suitable.

DE-U-91 11 755 beschreibt ein zweischaliges Wandsystem, bei dem der Raum zwischen den beiden Wandschalen und Teilvolumina der Wandschalen selbst mit dem losen -- Schüttgut Lehm bzw. seinen Gemischen ausgefüllt sind und Öffnungen 2 aufweist, aus denen die Dämmung rieselt, wenn die Putzschicht, die auch noch zusätzlich aufgrund der Öffnungen notwendig ist, beschädigt ist. DE-U-91 11 755 describes a two-shell wall system in which the space between the two wall shells and partial volumes of the wall shells themselves are filled with the loose - bulk material clay or its mixtures and has openings 2 from which the insulation trickles when the plaster layer, which is also additionally due to the openings is damaged.

Nachteilig an bekannten Betonfertigplatten ist, dass sie ungedämmt sind oder Abstandhalter aus korrosivem Metall aufweisen, um einen Hohlraum für eine Dämmung zwischen zwei Betonplatten zu bilden, wobei allerdings die Dämmung dieser bekannten Betonplatten einen schlechten Wärmedämmwert aufgrund der korrosiven Abstandhalter aufweisen, die Feuchtigkeit in das Innere der Dämmung transportieren. Ein weiteres Problem ist, dass Dämmstoffe oft schwierig und teuer zu entsorgen sind, wie zum Beispiel Polystyrol, was für die Anwender oft Probleme darstellt, da die Gesetze zur Entsorgung oft willkürlich und überraschend vom Gesetzgeber geändert werden. Ein weiteres Problem ist, dass bisher kein schüttbares, bzw. einblasbarer Dämmstoff bei Betonfertigschichtplatten verwendet werden konnte.The disadvantage of known precast concrete slabs is that they are uninsulated or have spacers made of corrosive metal to form a cavity for insulation between two concrete slabs, although the insulation of these known concrete slabs has a poor thermal insulation value due to the corrosive spacers that allow moisture to enter the interior the insulation. Another problem is that insulation materials, such as polystyrene, are often difficult and expensive to dispose of, which often poses problems for users because the laws on disposal are often arbitrarily and surprisingly changed by the legislature. Another problem is that up to now it has not been possible to use a pourable or blow-in insulation material for precast concrete panels.

Eine weitere Betonfertigplatte ist aus der EP-A-2 295 665 bekannt.Another precast concrete slab is from the EP-A-2 295 665 known.

Es bestand daher die Aufgabe den Stand der Technik zu verbessern und insbesondere gedämmte Betonfertigplatten zur Verfügung zu stellen und vorzugsweise gleichzeitig Dämmstoff zu entsorgen.The object was therefore to improve the state of the art and, in particular, to provide insulated precast concrete panels and, preferably, to dispose of insulating material at the same time.

Gegenstand der Erfindung ist eine Betonfertigschichtplatte nach Anspruch 1.The subject of the invention is a precast concrete slab according to claim 1.

Die Betonfertigschichtplatte weist vorzugsweise zwei Betonplatten auf, die vorzugsweise eine Bewehrung vorzugsweise mit Moniereisen, also Bewehrungsstahl aufweisen, als Bewehrung kann auch eine Textilbewehrung, vorzugsweise als Glasfaser, Carbonfaser dienen. Zwischen den beiden Betonplatten befindet sich ein Hohlraum, der mit Dämmstoff gefüllt wird.
