Description

Die Erfindung betrifft ein Gebäudeumhüllungselement mit mindestens einer, vorzugsweise stationär anzuordnenden, Halteeinrichtung und mit mindestens einem Folienkissen, das zwei äußere Folienlagen, die zwischen sich mindestens einen gasdicht geschlossenen Hohlraum bilden, in dem Gas, insbesondere Luft, enthalten ist, und einen Befestigungsabschnitt aufweist, in dem die beiden äußeren Folienlagen miteinander verbunden sind und mit dem das Folienkissen an der Halteeinrichtung verankert ist.The invention relates to a building envelope element with at least one, preferably stationary, holding device and with at least a foil cushion, the two outer layers of foil between them form at least one gas-tight cavity in which gas in particular air, is contained and has a fastening section, in which the two outer film layers are connected to each other and with the the foil cushion is anchored to the holding device.

Derartige Gebäudeumhüllungselemente sind bekannt und finden seit längerem unter anderem Verwendung zur Bildung von Foliendachsystemen sowie von Folienfassadensystemen. Foliendachsysteme und Folienfassadensysteme werden insbesondere bei der Errichtung von Einkaufzentren, Sporthallen, Vergnügungsparks und sonstigen gewerblichen Bauten verwendet, wo sich eine herkömmliche Bedachung nicht empfiehlt, sei es aus konstruktiven oder aus wirtschaftlichen Gründen. Building cladding elements of this type are known and have been found since longer use among other things for the formation of foil roof systems as well as foil facade systems. Foil roof systems and Foil facade systems are used especially in the construction of Shopping centers, sports halls, amusement parks and other commercial Buildings used where a conventional roofing is not recommended it for constructive or economic reasons.

Das Folienkissen wird durch mindestens zwei äußere Folienlagen gebildet, die gasdicht miteinander verbunden, gewöhnlich entlang ihrer Ränder miteinander verschweißt sind, um zwischen sich einen gasdicht geschlossen Hohlraum zu bilden. Während der Herstellung des Folienkissens wird in diesen Hohlraum Gas, insbesondere Luft, eingeblasen, wodurch die äußeren Folienlagen entsprechend gespannt werden und das Folienkissen seine beabsichtigte Form erhält. Daß in das Folienkissen eingeblasene Gas dient aber nicht nur zur Formgebung des Folienkissens, sondern auch zur thermischen Isolierung, was einen der Vorteile des Foliensystems ausmacht.The foil cushion is formed by at least two outer foil layers that gas-tightly connected to one another, usually along their edges are welded to form a gas-tight closed cavity between them form. During the manufacture of the foil cushion is in this cavity Gas, especially air, is blown in, causing the outer layers of film be stretched accordingly and the foil cushion its intended Takes shape. The fact that gas is blown into the foil cushion does not only serve for shaping the foil cushion, but also for thermal insulation, which is one of the advantages of the film system.

Die Halteeinrichtung besteht gewöhnlich aus einem Metallprofilrahmen, an dem das Folienkissen über seinen Befestigungsabschnitt verankert ist. Dabei sind die Folienlagen im Bereich der Verankerung zusammengepreßt und miteinander verschweißt. Dadurch wird zwar eine gute Verankerung der Folienlagen und somit des sie bildenden Folienkissens ermöglicht. Jedoch hat sich in der Praxis herausgestellt, daß im Bereich der Verankerung die Isolierwirkung des Foliensystems im wesentlichen vollständig verloren geht, da an jener Stelle das isolierende Luftpolster fehlt.The holding device usually consists of a metal profile frame which the foil cushion is anchored over its fastening section. there the film layers are compressed in the area of the anchoring and welded together. This will ensure good anchoring of the Foil layers and thus the foil cushion forming them. However It has been found in practice that in the area of anchoring The insulating effect of the film system is essentially completely lost, because the insulating air cushion is missing at that point.

Es ist deshalb eine Aufgabe der vorliegenden Erfindung, ein Gebäudeumhüllungselement der eingangs genannten Art derart zu verbessern, daß auch im Bereich der Verankerung mit der Halteeinrichtung eine thermische Isolierwirkung aufrechterhalten bleibt.It is therefore an object of the present invention to provide a Building cladding element of the type mentioned at the beginning improve that even in the area of anchoring with the holding device a thermal insulation effect is maintained.

Diese Aufgabe wird dadurch gelöst, daß bei einem Gebäudeumhüllungselement der eingangs genannten Art im Befestigungsabschnitt des Folienkissens mindestens ein thermisches Isolierelement angeordnet ist und die beiden äußeren Folienlagen durch das thermische Isolierelement voneinander beabstandet sind und dabei auf diesem aufliegen.This object is achieved in that Building envelope element of the type mentioned in the Fastening section of the foil cushion at least one thermal Insulating element is arranged and the two outer film layers through the thermal insulating element are spaced from each other and thereby lie on this.

Durch die erfindungsgemäße Integration von mindestens einem thermischen Isolierelement, das die beiden äußeren Folienlagen auch im Bereich des Befestigungsabschnittes auf Abstand hält, wird die bisher auftretende Kältebrücke beseitigt und die thermische Isolierwirkung des Gaspolsters bis in den Befestigungsabschnitt aufrechterhalten. Ebenfalls trägt das erfindungsgemäß vorgesehene thermische Isolierelement selbst zur thermischen Isolierung zwischen den beiden äußeren Folienlagen im Bereich der Verankerung bei, so daß auch das thermische Isolierelement selbst die Bildung einer Kältebrücke verhindert.The inventive integration of at least one thermal Insulating element that also covers the two outer layers of film in the area of Fastening section at a distance, is the previously occurring Cold bridge eliminated and the thermal insulation effect of the gas cushion up to maintain the mounting section. That also bears thermal insulation element provided according to the invention itself for thermal insulation between the two outer film layers in the area the anchoring, so that the thermal insulating element itself Prevention of a cold bridge.

Ein weiterer Vorteil der Erfindung besteht darin, daß die Folienlagen zusammen mit dem dazwischen liegenden thermischen Isolierelement bereits bei der Herstellung im Werk entsprechend gasdicht miteinander verbunden, vorzugsweise verschweißt werden können.Another advantage of the invention is that the film layers together with the thermal insulation element in between connected in a gas-tight manner during manufacture in the factory, can preferably be welded.

Bei einer bevorzugten Ausführung der Erfindung, bei welcher die Halteeinrichtung einen Eingriffsabschnitt für den Eingriff mit dem Befestigungsabschnitt des Folienkissens aufweist, ist der Befestigungsabschnitt des Folienkissens mit dem darin angeordneten thermischen Isolierelement in Eingriff mit dem Eingriffsabschnitt bringbar. Bei einer Weiterbildung dieser Ausführung, bei welcher der Eingriffsabschnitt zwei Klemmabschnitte aufweist, zwischen denen der Befestigungsabschnitt einklemmbar ist, ist der Befestigungsabschnitt des Folienkissens mit dem darin angeordneten thermischen Isolierelement zwischen den Klemmabschnitten einklemmbar. Gewöhnlich sind die Klemmabschnitte von Metallprofilen gebildet.In a preferred embodiment of the invention, in which the Holding device an engagement portion for engagement with the Fastening section of the foil cushion is the Fastening section of the foil cushion with the arranged therein Thermal insulating element can be brought into engagement with the engagement section. at a development of this embodiment, in which the engagement section two Has clamping sections between which the fastening section can be clamped, the fastening section of the foil cushion with the thermal insulation element arranged therein between the Clamping sections can be clamped. Usually the clamping sections are from Metal profiles formed.

Bei einer weiteren bevorzugten Ausführung der Erfindung, bei welcher im Befestigungsabschnitt des Folienkissens die äußeren Folienlagen an einer Verbindungsstelle direkt miteinander verbunden, vorzugsweise verschweißt, sind, ist das thermische Isolierelement benachbart zur Verbindungsstelle innerhalb des Hohlraumes des Folienkissens angeordnet. Dabei wird gewöhnlich zwischen der Verbindungsstelle und dem benachbart angeordneten thermischen Isolierelement noch ein weiteres kleines Gaspolster gebildet, welches ebenfalls eine thermische Isolierwirkung besitzt. In a further preferred embodiment of the invention, in which Fastening section of the foil cushion on the outer foil layers Connection point directly connected, preferably welded, are, the thermal insulating element is adjacent to the connection point arranged within the cavity of the foil cushion. Doing so usually between the junction and the neighboring arranged thermal insulation element yet another small Gas cushion formed, which also has a thermal insulation effect.

Außerdem verhindert bei dieser Anordnung das thermische Isolierelement eine Kältebrücke von der Verbindungsstelle zu dem mit Gas gefüllten Hohlraum des Folienkissens, so daß das thermische Isolierelement nicht nur zwischen den beiden äußeren Folienlagen, sondern auch zur außen gelegenen Verbindungsstelle eine ausreichende isolierende Wirkung entfaltet.This arrangement also prevents the thermal insulating element a cold bridge from the junction to the gas-filled one Cavity of the foil cushion, so that the thermal insulating element not only between the two outer layers of film, but also to the outside located connecting point develops a sufficient insulating effect.

Bei einer weiteren gegenwärtig besonders bevorzugten Ausführung, bei welcher am Befestigungsabschnitt des Folienkissens eine Kederfolie angebracht ist, die außerhalb des Folienkissens mit einem Kedertau zur Befestigung an der Halteeinrichtung verbunden ist, umschließt die Kederfolie das thermische Isolierelement. Gewöhnlich umschließt die Kederfolie auch das Kedertau, wobei die beiden Enden der Kederfolie an der Verbindungsstelle mit den Folienlagen verbunden, vorzugsweise verschweißt, sind.In another currently particularly preferred embodiment, at which on the fastening section of the foil cushion is a keder foil attached to the outside of the foil cushion with a piping rope Attachment to the holding device is connected, encloses the keder film the thermal insulating element. The keder film usually also encloses the piping rope, the two ends of the piping film on the Connection point connected to the film layers, preferably welded, are.

Gewöhnlich ist der Befestigungsabschnitt des Folienkissens mit der Verbindungsstelle an der Halteeinrichtung verankert.Usually the fastening section of the foil cushion is with the Connection point anchored to the holding device.

Bei einer weiteren Ausführung der Erfindung, bei welcher der Befestigungsabschnitt einen umlaufenden flanschartigen Randabschnitt des Folienkissens bildet, bildet das thermische Isolierelement ein umlaufendes Element.In a further embodiment of the invention, in which the Fastening section a circumferential flange-like edge section of the Forms foil cushion, the thermal insulating element forms a circumferential Element.

Zweckmäßigerweise ist das thermische Isolierelement als Steg ausgebildet.The thermal insulating element is expediently designed as a web.

Das thermische Isolierelement sollte mit den äußeren Folienlagen verbunden, vorzugsweise verschweißt, sein. Hierzu wird für die thermische Trennung vorzugsweise ein Trennprofil, das beispielsweise aus EPDM, Gummi, Faserwerkstoffen oder anderen schlecht wärmeleitenden Materialien besteht, innerhalb der umlaufenden randabschließenden Schweißung zwischen die Folienlagen eingelegt und so verschweißt, daß ein Verrutschen nicht möglich ist. The thermal insulation element should be connected to the outer foil layers, preferably welded. This is done for thermal separation preferably a separating profile made, for example, of EPDM, rubber, Fiber materials or other poorly heat-conducting materials, within the circumferential edge sealing weld between the Foil layers inserted and welded so that slipping is not possible is.
