Stand der TechnikState of the art

Aufblasbare Zelte werden zumeist aus Mehrkammerfolien hergestellt, wobei die äußere und innere Folie metallisiert sein können. Die miteinander verbundenen Luftkammern sind 10 bis 100 cm groß. Damit die Luftzirkulation in den Kammern deutlich geringer wird, müssten die Kammern kleiner als 1 cm sein oder in mehreren Lagen angeordnet sein, ähnlich einer Mehrscheibenverglasung beim Fenster. Bisher sind keine aufblasbaren Waabenstrukturen herstellbar und eine mehrschalige aufblasbare Konstruktion zu teuer. Mehrwandige metallisierte Strukturen sind nicht möglich, da die Folien dann nicht verschweisbar sind. Eine mehrwandige aufblasbare Konstruktion wird in den oben genannten Patenten beschrieben. Lediglich die Firma Thermotents ( WO 2016/024258 ) gelingt es einen guten Wärmedurchgangskoeffizienten für die Zeltkonstruktion zu erzielen, indem sie in einem konventionell aufgebautem Zelt (Zeltplane + Gestänge) ein inneres Zelt aus Dämmmaterial aufhängt.Inflatable tents are usually made of multi-chamber films, wherein the outer and inner film can be metallized. The interconnected air chambers are 10 to 100 cm in size. Thus, the air circulation in the chambers is significantly lower, the chambers would have to be smaller than 1 cm or arranged in multiple layers, similar to a multi-pane glazing at the window. So far, no inflatable honeycomb structures can be produced and a multi-shell inflatable structure too expensive. Multi-walled metallized structures are not possible because the films are then not verschweisbar. A multiwall inflatable construction is described in the above patents. Only the company Thermotents ( WO 2016/024258 ) it is possible to achieve a good heat transfer coefficient for the tent construction by hanging an inner tent made of insulating material in a conventionally constructed tent (tarpaulin + poles).

Seit einigen Jahren gibt es das dropstitch-Verfahren. Es ermöglich den Bau aufblasbarer ebender Strukturen mit glatten Oberflächen, die aus nur einer Kammer bestehen. Auch hier ist der Wärmedurchgang auf ca. 1,5 W/m2K begrenzt, da zwischen den Deckfolien eine Luftzirkulation stattfindet.For some years there is the drop stitch method. It allows the construction of inflatable structures with smooth surfaces consisting of only one chamber. Again, the heat transfer is limited to about 1.5 W / m 2 K, as between the cover sheets air circulation takes place.

Aus dem Baubereich ist eine leichte hochisolierende, reflektierende und dünne Isolierung bekannt, die aus mehreren metallisierten Schaumfolien (10 bis 18) besteht, die beim Transport auf 1cm zusammengepresst werden kann und im Arbeitszustand auf ca. 2 cm aufquillt. Eine 2 cm dicke Multifoil-Matte besitzt den Dämmwert von 14 cm PU-Schaum. Bisher gibt es noch kein Patent für eine aufblasbare zweiwandige Konstruktion mit integrierter Multifoil-Isolierung. From the construction sector, a light highly insulating, reflective and thin insulation is known, which consists of several metallized foam films (10 to 18), which can be compressed to 1 cm during transport and swells in the working state to about 2 cm. A 2 cm thick multifoil mat has the insulation value of 14 cm PU foam. So far, there is no patent for an inflatable two-wall construction with integrated multifoil insulation.

Beschreibungdescription

Kombiniert man dropstitch-Material, bestehend aus 2 Deckfolien (1), die mit tausenden Fäden (2) auf Abstand gehalten werden, mit Multifoil-Isolierung (3), entsteht ein 5 bis 10mm dicke aufblasbare Matte mit einem Dämmwert zwischen 0,25 und 0,5 W/m2K. Auf Grund der Art und Weise der Herstellung des dropstitch-Material besteht die Möglichkeit zwischen den Deckfolien des dropstitch-Materials eine Multifoil-Isolierung einzunähen. Das gedämmte dropstitch-Material kann nun konventionell zu aufblasbaren Strukturen weiter verarbeitet werden. Beim Nähvorgang wird die Multifoil-Isolierung perforiert. Die Perforation führt zu Verdickungen im Bereich des Loches, die wiederum zu Vereinzelung der Folien des Multifoil-Materials führen. Dadurch entstehen Luftschichten zwischen den Folien.Combine dropstitch material, consisting of 2 cover sheets ( 1 ) with thousands of threads ( 2 ) are kept at a distance with multifoil insulation ( 3 ), creates a 5 to 10mm thick inflatable mat with an insulating value between 0.25 and 0.5 W / m 2 K. Due to the way the production of the drop stitch material, there is the possibility between the cover sheets of the drop stitch material Sew in multifoil insulation. The insulated dropstitch material can now be conventionally processed into inflatable structures. During sewing, the multifoil insulation is perforated. The perforation leads to thickening in the area of the hole, which in turn lead to separation of the films of the multi-oily material. This creates air layers between the films.
