Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung dahingehend weiterzuentwickeln, dass in einfacher und insbesondere kostengünstiger Weise eine leicht zu installierende und nachträglich einzubauende Vorrichtung geschaffen wird.Starting from this prior art, the invention has for its object to further develop a generic device in that in a simple and particularly cost-effective manner an easy to install and subsequently be incorporated apparatus is provided.

Zur Lösung dieser Aufgabenstellung ist vorgesehen, dass die Leitung durch zumindest eine Geschossdecke geführt, die Außenwandung im Bereich der Geschossdecke unterbrochen ausgebildet und zwischen der Leitung und der Geschossdecke ein, einen Spaltraum zwischen der Leitung und der Geschossdecke dichtend ausfüllendes Dämmelement angeordnet ist.To solve this problem, it is provided that the line guided by at least one floor slab, the outer wall in the area of the floor slab formed interrupted and between the line and the floor ceiling, a gap between the pipe and the floor slab sealing ausfüllendes insulating element is arranged.

Üblicherweise wird eine aus dem Stand der Technik bekannte Vorrichtung mit allen drei Konstruktionselementen, nämlich der Außenschale, der Leitung für die Abluft und der Wärmedämmung über die gesamte Höhe hinweggeführt, so dass sich hieraus auch eine bestimmte Vorgehensweise beim Aufbau derartiger Vorrichtungen ergibt. Derartige Vorrichtungen sind in der Regel nicht geeignet, ohne großen Aufwand in Gebäude nachträglich eingebaut zu werden. Vielmehr muß bereits bei der Erstellung des Gebäudes entsprechend vorgegangen werden, wobei parallel mit dem Baufortschritt des Gebäudes, insbesondere im Hinblick auf die Erstellung der einzelnen Geschosse die Vorrichtung aufgemauert wird. Hierdurch ergeben sich aber auch im Kontaktbereich zwischen den Geschossdecken und der Vorrichtung wärmeschwankungsbedingte Materialausdehnungen, die in nicht seltener Weise zu Rissen im Bereich der Durchführung der Vorrichtung durch Geschossdecken führen.Usually, a device known from the prior art with all three construction elements, namely the outer shell, the duct for the exhaust air and the thermal insulation is carried over the entire height, so that there is also a certain procedure for the construction of such devices. Such devices are usually not suitable to be retrofitted in buildings without much effort. Rather, it is necessary to proceed accordingly already in the construction of the building, wherein the device is bricked up in parallel with the construction progress of the building, in particular with regard to the creation of the individual projectiles. However, this also results in the contact area between the floor slabs and the device heat fluctuation-related material expansions that result in not infrequent ways to cracks in the field of implementation of the device through floor slabs.

Bei der erfindungsgemäßen Vorrichtung ist vorgesehen, dass lediglich die Leitung sich über die gesamte Höhe des Gebäudes, d.h. von der Feuerstätte bis zum oftmals dachseitig vorgesehenen Ausgang erstreckt, während die Wärmedämmeinrichtung und die Außenwandung jeweils im Bereich der Geschossdecken abgesetzt sind. Eine derartige Vorrichtung lässt sich in einfacher Weise nachträglich in bestehende Gebäude integrieren, da zu diesem Zweck lediglich entsprechende Kernbohrungen in die Geschossdecken möglichst koaxial eingebracht werden müssen, um im Anschluß hieran die Leitung einzusetzen, welche dann mit der Wärmedämmeinrichtung ummantelt wird. Im Bereich der Geschossdecken wird sodann der Spaltraum zwischen der Leitung und der Geschossdecke mit einem Dämmelement dichtend ausgefüllt, bevor in einem letzten Schritt die Außenwandung zwischen den Geschossdecken bzw. Geschossböden errichtet wird. Auf diese Weise lässt sich eine kostengünstig herstellbare Vorrichtung mit geringem Arbeitsaufwand in ein Gebäude integrieren, wobei selbstverständlich derartige erfindungsgemäße Vorrichtungen auch in Neubauten mit zunehmendem Baufortschritt einbauen lassen.In the device according to the invention it is provided that only the line extends over the entire height of the building, ie from the fireplace to the often roof side provided output, while the heat insulation device and the outer wall deposited in each case in the area of the floor slabs are. Such a device can be integrated into existing buildings in a simple manner, since for this purpose only corresponding core holes in the floor slabs must be inserted as coaxially as possible to use the line thereafter, which is then covered with the thermal insulation device. In the area of floor slabs, the gap space between the duct and the floor slab is then filled with an insulating element in a sealing manner, before the outer wall between the floor slabs or floor slabs is erected in a final step. In this way, a low-cost manufacturable device can be integrated into a building with little effort, of course, such inventive devices can be installed in new buildings with increasing construction progress.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Außenschale aus plattenförmigen Elementen besteht, die vorzugsweise aus Gipskartonplatten gebildet sind. Diese Ausgestaltung hat den Vorteil, dass relativ leichte Bauelemente für die Außenschale verwendet werden. Auf die Verwendung von sogenannten Mantelsteinen kann verzichtet werden. Die Gipskartonplatten können in einfacher Weise an zuvor aufgestellten und mit Decke und Boden verbundenen Ständern befestigt werden. Ein weiterer Vorteil besteht darin, dass die Gipskartonplatten aufgrund ihrer Materialstärke nur relativ wenig Wohnfläche im Vergleich zu den zuvor genannten Mantelsteinen in Anspruch nehmen.According to a further feature of the invention it is provided that the outer shell consists of plate-shaped elements, which are preferably formed from plasterboard. This embodiment has the advantage that relatively lightweight components are used for the outer shell. On the use of so-called mantle stones can be omitted. The plasterboard can be easily attached to previously set up and connected to the ceiling and floor stands. Another advantage is that the plasterboard due to their material thickness take up relatively little living space compared to the aforementioned mantle stones.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Außenschale beabstandet zur Wärmedämmeinrichtung angeordnet ist. Durch die Vermeidung des direkten Kontaktes mit der Wärmedämmeinrichtung werden auch hohe Temperaturen der Außenschale vermieden, so dass die Außenschale keine F-Klassifizierung aufweisen muß und lediglich als Sichtschutz dient.According to a further feature of the invention it is provided that the outer shell is arranged at a distance from the heat-insulating device. By avoiding the direct contact with the heat-insulating device, high temperatures of the outer shell are avoided, so that the outer shell does not have to have an F-classification and merely serves as a screen.

Es ist ferner vorgesehen, dass der Abstand zwischen der Außenschale und der Leitung größer ist, als die Breite des Spaltraumes zwischen der Leitung und der Geschossdecke. Hierdurch ist sichergestellt, dass die Außenschale nicht im Bereich des Spaltraums aufgestellt ist und dass die Außenschale auch den Spaltraum unzugänglich macht. Eine Beschädigung des Dämmelementes im Spaltraum durch nachfolgende handwerkliche Arbeiten oder durch den bestimmungsgemäßen Wohngebrauch eines Gebäudes wird hierdurch vermieden.It is further contemplated that the distance between the outer shell and the conduit is greater than the width of the gap space between the conduit and the floor slab. This ensures that the outer shell is not in the area the gap space is set up and that the outer shell makes the gap space inaccessible. Damage to the insulating element in the gap by subsequent manual work or by the intended residential use of a building is thereby avoided.

Das Dämmelement ist als gewickelte oder segmentierte Rohrschale ausgebildet, die vorzugsweise aus einzelnen, untereinander verklebten Segmenten besteht. Um die Feuerwiderstandsdauer üblicher Geschossdecken bereitstellen zu können, hat es sich als vorteilhaft erwiesen, das Dämmelemente mit einer Rohdichte zwischen 20 und 600 kg/m3, insbesondere zwischen 20 und 200 kg/m3 auszubilden.Preferably, the insulating element has a melting point of at least 600 ° C, in particular of more than 900 ° C, preferably of more than 1000 ° C.
