Abstract

For the preheating of fresh air which is to be fed to a room by means of a ventilator, is forced through the outer wall, bypassing windows in the process, and takes up some of the heat discharged to the outside as well as any facade heat which may be stored, and for the simultaneous improvement of the sound insulation, use is made of facing elements which comprise two gypsum- plasterboard/ rigid-foam composite panels 2,4 of different thicknesses. The composite panels 2,4 are spaced apart from one another by means of gypsum- plasterboard panel sections 9,10 which continue all the way around the panel borders and are arranged at certain locations in the inner region, it being the case that the gypsum-plasterboard panels 7,8 of the two composite panels 2,4 are directed towards one another. Air through- passages 17 open out into the layer of air 3 delimited by said composite panels, and the air is blown into the room via said through-passages. With the formation of a second layer of air, the facing elements are fastened on lathing arranged on the outer wall and are rendered on the outside. <IMAGE>

Description

Nr. 390 628No. 390 628

Die Erfindung betrifft ein Vorsatzelement für eine Klimawand, bei der die Frischluft unter Umgehung der Fenster von außen nach innen mittels eines Ventilators durch das Außenwandgefüge gedrückt wird und dabei einen Teil der angespeicherten Fassadenwärme mitnimmt.The invention relates to an attachment element for a climate wall in which the fresh air is bypassed through the windows from the outside inwards by means of a fan through the outer wall structure and thereby takes part of the stored facade heat.

Die Anordnung einer zusätzlichen Wärmedämmschicht an den Außenseiten von Außenwänden bei Neubauten und Altbausanierungen ist im Zuge der Energiesparbemühungen üblich geworden. Dabei ist, um den die Dämmung verschlechternden Feuchtigkeitsgehalt der Dämmschicht so gering als möglich zu halten, auch bereits mehrfach vorgeschlagen worden (z. B. AT-PS 363 655 und 344 380) mit Abstand außerhalb der Dämmschicht eine Vorsatzschicht anzubringen, sodaß die Dämmschicht belüftet und gegen Regen geschützt ist.The arrangement of an additional layer of thermal insulation on the outside of outside walls in new and old building renovations has become common in the course of energy-saving efforts. In order to keep the moisture content of the insulation layer which deteriorates as low as possible, it has also been proposed several times (e.g. AT-PS 363 655 and 344 380) to place a facing layer outside the insulation layer so that the insulation layer is ventilated and is protected against rain.

In der nicht vorveröffentlichten AT-PS 386 066 wird ein Wandaufbau beschrieben, bei dem durch eine äußere und innere Vorsatzschicht zwei Luftschichten ausgebildet sind, die durch die Wand durchdringende Kanäle verbunden sind, wobei ein Ventilator für einen Lufttransport von außen nach innen sorgt. Die von der äußeren Luftschicht umfaßte Luft wird dabei einerseits durch Wärmeabgabe aus der sonnenbestrahlten Vorsatzschicht und andererseits aus der Wand vorgewärmt, sodaß sich Heizkosten vermindern.In the unpublished AT-PS 386 066 a wall structure is described in which two air layers are formed by an outer and inner facing layer, which are connected by channels penetrating through the wall, a fan ensuring air transport from the outside to the inside. The air enclosed by the outer air layer is preheated on the one hand by heat emission from the sun-exposed facing layer and on the other hand from the wall, so that heating costs are reduced.

Die Erfindung hat es sich nun zur Aufgabe gestellt, ein zum Aufbau der eingangs genannten Wand besonders geeignetes Vorsatzelement zu schaffen. Dies wird erfindungsgemäß dadurch erreicht, daß das Vorsatzelement in aus zwei vorzugsweise unterschiedlich starken Gipskarton-Hartschaum-Verbundplatten und diese in Abstand haltenden an den Plattenrändem durchgehend und dazwischen stellenweise angeordneten streifenförmigen Gipskartonplattenabschnitten besteht, wobei die Gipskartonplatten der Verbundplatten des Vorsatzelementes einander zugekehrt sind.The invention has now set itself the task of creating a particularly suitable for the construction of the aforementioned wall attachment element. This is achieved according to the invention in that the facing element consists of two preferably differently thick gypsum plasterboard rigid foam composite panels and these spaced strip-like gypsum board sections arranged on the edges of the panel and in between, the gypsum board panels of the composite panels of the facing element facing each other.

Dadurch ergeben sich neue Möglichkeiten zur energiesparenden, indirekten Raumbelüftung, zum Energierückgewinn und Energiezugewinn, da die vom Ventilator, der wahlweise außerhalb, oberhalb (Dachgeschoß) oder unterhalb (Keller) der Klimawand angeordnet werden kann, transportierte Frischluft von außen nach innen durch das Wandgefüge gedrückt wird, und dabei Wärme aufnimmt. Durch das Vorsatzelement wird aber nicht nur der Transport von gespeicherter Fassadenwärme in den Raum ermöglicht, sondern durch die Verwendung der Gipskartonplatten auch ein verbesserter Schallschutz erzieltThis opens up new possibilities for energy-saving, indirect room ventilation, energy recovery and energy gain, since the fresh air transported by the fan, which can be arranged outside, above (top floor) or below (basement), pushes fresh air from outside to inside through the wall structure and absorbs heat. The front element not only enables the stored facade heat to be transported into the room, but also improves sound insulation by using the plasterboard

In einer bevorzugten Ausführung ist vorgesehen, daß die Hartschaumdeckschicht der außenseitig angeordneten Gipskarton-Hartschaum-Verbundplatte eine über die ganze Deckschicht verteilte Vielfachlochung aufweist, die die Hartschaumdeckschicht bis zur Gipskartonplatte durchringt. Durch die Vielfachlochung der äußeren Hartschaumdeckschicht wird die Putzhaftung verbessert. Die große Anzahl von bis zur Gipskartonplatte durchgehenden Löchern ermöglicht eine sichere Haftung auch schwerer mineralischer Putzbeläge und entspannt die Hartschaumdämmschicht, sodaß Volumsänderungen schädlichen Ausmaßes nicht auftreten. Auch ein Putzrisse verursachender Hitzestau im Putz und Putzträger kann dadurch nicht in Erscheinung treten, da sich durch die Vielfachlochung unzählige Wärmebrücken vom Außenputz zur Gipskartonplatte ergeben. Da diese innenseitig von der Frischluft beströmt wird, wird ein Fassadenwärmetransfer bewirkt.In a preferred embodiment it is provided that the hard foam cover layer of the plasterboard-hard foam composite panel arranged on the outside has a multiple perforation distributed over the entire cover layer, which penetrates the hard foam cover layer up to the plasterboard panel. The plaster adhesion is improved by the multiple perforation of the outer hard foam cover layer. The large number of holes through to the gypsum plasterboard enables even heavy mineral plaster coverings to adhere securely and relaxes the rigid foam insulation layer, so that volume changes of harmful dimensions do not occur. Even heat build-up in the plaster and plaster base that causes plaster cracks cannot occur because the multiple perforations result in countless thermal bridges from the outer plaster to the plasterboard. Facade heat transfer is effected because fresh air flows on the inside.

Nachstehend wird nun die Erfindung an Hand der Figuren der beiliegenden Zeichnung näher beschrieben, ohne darauf beschränkt zu sein.The invention will now be described in more detail with reference to the figures of the accompanying drawing, without being limited thereto.

Die Fig. 1 zeigt einen Schnitt durch einen Teil eines erfindungsgemäßen Vorsatzelementes und Fig. 2 ebenfalls im Schnitt das Vorsatzelement nach Fig. 1 an einer Wand montiert.Fig. 1 shows a section through part of an attachment element according to the invention and Fig. 2 also in section the attachment element according to Fig. 1 mounted on a wall.

Das Vorsatzelement besteht aus zwei Verbundplatten (2), (4), die jeweils aus einer Gipskartonplatte (7), (8) und einer Hartschaumdeckschicht (18), (19) bestehen. Zwischen den beiden Verbundplatten (2), (4) sind distanzierende Gipskartonplattenabschnitte (9), (10) angeordnet, durch die eine Luftschicht (3) begrenzt wird. Entlang der vertikalen Ränder des Vorsatzelementes, das bevorzugt geschoßhoch ausgebildet ist, sind die Gipskartonplattenabschnitte (9) in Form von Streifen vorgesehen, während im Inneren kurze Abschnitte (10) die Verbundplatten (2), (4) nur stellenweise verbinden. Die beiden Gipskartonplatten (7), (8) weisen zueinander, und die Hartschaumdeckschichten (18), (19) nach außen. Für die Montage an der Wand (6) sind durchgehende Bohrungen (12) vorgesehen, durch die mit Beilagscheiben unterlegte Befestigungsschrauben (13) eingesetzt werden können. Hiezu wird an der Wand (6) eine Lattung mittels Schrauben (16) verdübelt, die entlang der Ränder des Vorsatzelementes aus durchgehenden Randlatten (14) und im übrigen Bereich aus kurzen Lattenstücken (15) besteht. Nach Montage des Vorsatzelementes besteht dadurch zwischen der Hartschaumdeckschicht (18) der inneren Verbundplatte (4) und der Wand (6) eine zweite, innere Luftschicht (5). Um den Transport der Luft von außen durch die Wand (6) zu ermöglichen, sind sowohl in der inneren Verbundplatte (4) als auch in der Wand (6) die schematisch angedeuteten Luftdurchlässe (17) ausgebildet.The front element consists of two composite panels (2), (4), each consisting of a plasterboard panel (7), (8) and a hard foam cover layer (18), (19). Between the two composite panels (2), (4) spacing plasterboard sections (9), (10) are arranged, through which an air layer (3) is delimited. The gypsum plasterboard sections (9) are provided in the form of strips along the vertical edges of the facing element, which is preferably storey-high, while short sections (10) connect the composite boards (2), (4) only in places. The two plasterboard panels (7), (8) face each other, and the hard foam cover layers (18), (19) to the outside. Through holes (12) are provided for mounting on the wall (6), through which fastening screws (13) with washers can be inserted. For this purpose, battens are doweled on the wall (6) by means of screws (16), which consist of continuous edge battens (14) along the edges of the facing element and short battens pieces (15) in the remaining area. After assembly of the facing element, there is a second, inner air layer (5) between the hard foam cover layer (18) of the inner composite panel (4) and the wall (6). In order to enable the air to be transported from the outside through the wall (6), the schematically indicated air passages (17) are formed both in the inner composite panel (4) and in the wall (6).

Die Ausbildung der inneren Luftschicht (5), die von der äußeren Luftschicht (3) durch die innere, aufgrund der Hartschaumdeckschicht (18) ebenfalls wärmedämmende Verbundplatte (4) abgeteilt ist, wird die eingangs beschriebene Energieeinsparung noch verbessert. Die innere Luftschicht (5) nimmt die von der Wand (6) abgegebene Wärme auf, deren Übertragung an die äußere Luftschicht (3) durch die Verbundplatte (4) bzw. deren Hartschaumdeckschicht (18) behindert wird. Die äußere Luftschicht (3) wird daher im wesentlichen nur von der Fassadenwärme und die innere Luftschicht (5) von der Wandwärme erwärmt, sodaß ein großer Teil der abgegebenen Wärme dem Innenraum zugeführt wird. Von der inneren Luftschicht (5) nach außen durch die Verbundplatten (4) abgegebene Wärme wird von der äußeren Luftschicht (3) aufgenommen und somit ebenfalls wieder dem Raum zugeführt.The formation of the inner air layer (5), which is divided from the outer air layer (3) by the inner, due to the hard foam cover layer (18) also heat-insulating composite panel (4), the energy saving described above is further improved. The inner air layer (5) absorbs the heat given off by the wall (6), the transfer of which to the outer air layer (3) is hindered by the composite panel (4) or its hard foam cover layer (18). The outer air layer (3) is therefore essentially only heated by the facade heat and the inner air layer (5) by the wall heat, so that a large part of the heat given off is supplied to the interior. Heat emitted from the inner air layer (5) to the outside through the composite panels (4) is absorbed by the outer air layer (3) and thus also returned to the room.
