Description
Die Erfindung bezieht sich auf eine rollbare Wärmedämmbahn nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a rollable thermal insulation sheet according to the preamble of the claim 1.
Bereits bekannte rollbare Wärmedämmbahnen wurden in der Weise hergestellt, daß vorher einzeln angefertigte Abschnitte einer Hartschaumstoffplatte nebeneinander auf eine Kaschierungsbahn aufgeklebt wurden. Diese Art der Herstellung ermöglicht es zwar, Spalte zwischen den einzelnen Abschnitten des Hartschaumstoffkörpers zu vermeiden und beim Verlegen der in eine Ebene abgerollten Bahn eine praktisch ununterbrochene Dämmstoffschicht zu erhalten. Andererseits ist die getrennte Herstellung der einzelnen Abschnitte des Hartschaumstoffkörpers, das Aufbringen einer Klebstoffschicht auf die Kaschierung und das Ausrichten der Abschnitte des Hartschaumstoffkörpers auf dieser umständlich und zeitraubend.Already known rollable thermal insulation sheets were produced in such a way that previously individually Manufactured sections of a rigid foam board glued next to one another on a liner became. Although this type of manufacture makes it possible to create gaps between the individual sections of the To avoid rigid foam body and a practical when laying the unrolled web in a plane to obtain an uninterrupted insulation layer. On the other hand, the separate production of each Sections of the rigid foam body, the application of an adhesive layer on the lamination and the Aligning the sections of the rigid foam body on this awkward and time consuming.
Es ist ferner bekannt, eine größere Hartschaumstoffplatte auf die Kaschierungsbahn aufzukleben und — da das spanlose Einschneiden von Hartschaumstoff wegen des Festklemmens eines /lachen Schneidmessers mit nach dem bisherigen Stand der Technik noch nicht überwundenen Schwierigkeiten verbunden war — durch Einsägen in einzelne Abschnitte zu zerteilen. Weiter sind Hartschaumstoffplatten bekannt, deren Hartschaumstoffkörper durch Aufschäumen unmittelbar auf die Kaschierung aufgebracht ist Auch diese können zur Herstellung einer rollbaren Wärmedämmbahn durch Einsägen des beispielsweise aus Polyurethan bestehenden Hanschaumstoffkörpers bis auf die Kaschierung oder, soweit der Hartschaumstoffkörper aus einem stark bröckelnden Material wie Polystyrol besteht, durch Trennung mit Hilfe von Hitzdrähten abschnittsweise unterteilt werden. Beide Unterteilungsarten führen jedoch zur Entstehung eines Spaltes an den Trennstellen. Eine Trennung durch Einsägen ist außerdem mit Spanbildung verbunden. Schnittverluste sollen aber wegen der hohen Kosten des Rohmaterials von Hartschäumen möglichst vermieden werden.It is also known to use a larger rigid foam board to stick on the liner and - because of the non-cutting cutting of rigid foam the clamping of a / flat cutting knife with according to the previous state of the art not yet overcome difficulties - to cut into individual sections by sawing. Rigid foam panels are also known whose rigid foam bodies are foamed directly is applied to the lamination. These can also be used to produce a rollable thermal insulation sheet by sawing the foam body made of polyurethane, for example, down to the lamination or, if the rigid foam body is made of a highly crumbling material such as polystyrene consists, can be subdivided in sections by separation with the help of hot wires. However, both types of subdivision lead to the formation of a gap on the Separation points. Separation by sawing in is also associated with chip formation. Cutting losses but should be avoided as much as possible because of the high cost of the raw material of rigid foams.
rollbare Wärmedämmbahn, die Wärmeverluste durch einen Spalt vermeidet, zu schaffen, die einfacher und wirtschaftlicher herstellbar ist als es nach dem bisherigen Stande der Technik möglich war.rollable thermal insulation membrane that avoids heat loss through a gap, creating that easier and can be produced more economically than was possible according to the prior art.
Ein geeignetes Mittel hierzu ist die Schneidvorrichtung nach dem Hauptpatent 24 08 319.A suitable means for this is the cutting device according to the main patent 24 08 319.
Unter Ausnutzung dieses Mittels besteht die Lösung der Aufgabe erfindungsgemäß in einer der eingangsUsing this means, the object is achieved according to the invention in one of the above
ίο genannten Gattung entsprechenden rollbaren Wärmedämmbahn,
deren Hartschaumstoffkörper durch unmittelbares Aufschäumen fest mit der Kaschierung
verbunden ist
Durch diese Lösung wird erreicht, daß der Hartschaumstoffkörper
der rollbaren Wärmedämmbahn, obwohl er vor seiner Unterteilung durch bis auf die
Kaschierung geführte Einschnitte als Hartschaumstoffplatte oder -bahn unmittelbar auf die Kaschierungsbahn
aufgebracht ist, keine spanbildenden Trennvorgänge erfordert und nach dem Verlegen in einer Ebene eine in
sich geschlossene Wärmedämmschicht bildetίο mentioned type corresponding rollable thermal insulation sheet, the rigid foam body is firmly connected to the lamination by direct foaming
This solution ensures that the rigid foam body of the rollable thermal insulation sheet, although it is applied directly to the lamination sheet as a rigid foam sheet or sheet prior to its subdivision through incisions leading up to the lamination, does not require any chip-forming separating processes and after laying in a plane an in closed thermal insulation layer is formed
Die Kaschierung kann von einer Bitumendichtungsbahn gebildet sein, die aus handelsüblicher Dachpappe oder einer Spezialdachfolie, insbesondere einem folienförmigen Kunststoffdachbelagwerkstoff, z. B. einem Thermoplast oder einem Elastomer, besteht Solche Kaschierungsmaterialien sind an sich bekanntThe lamination can be formed by a bitumen sealing membrane made from commercially available roofing felt or a special roof film, in particular a film-shaped plastic roof covering material, e.g. B. a Such lamination materials are known per se
Die rollbare Wärmedämmbahn kann auf ihrer der Kaschierung entgegengesetzten Flachseite mit Unebenheiten zur Bildung von Dampfableitungshohlräumen sowie mit einer als Dampfbremse dienenden Metallfolienkaschierung versehen sein.The rollable thermal insulation sheet can have unevenness on its flat side opposite the lamination for the formation of vapor discharge cavities as well as with a metal foil lamination serving as a vapor barrier be provided.
Ferner kann zwischen dem Hartschaumstoffkörper und der feuchtigkeitsdichten Kaschierung eine mit Perforationen versehene Trennschicht angeordnet sein, so daß der Hartschaumstoffkörper nur im Bereich der Perforationen unmittelbar an der Kaschierung festhaftet Dadurch wird erreicht, daß in dem labyrinthartigen Gebiet, wo sich die beispielsweise aus Papier bestehende Trennschicht befindet, zwischen dem Hartschaumstoffkörper und der feuchtigkeitsdichten Kaschierung keine unmittelbare Verbindung, sondern ein Druckausgleichsraum gebildet wird, durch den verdampfende Feuchtigkeit bei Überdruck nach außen abgeführt werden kann, während die unmittelbare feste Verbindung des Hartsciiaumstoffkörpers in den Perforationsbereichen mit der feuchtigkeitsdichten Kaschierung einen festen Halt der feuchtigkeitsdichten Kaschierung an dem Hartschaumstoffkörper gewährleistetFurthermore, a with Perforations provided separating layer be arranged so that the rigid foam body only in the area of Perforations adhered directly to the lamination. This ensures that in the labyrinthine Area where the separating layer, for example made of paper, is located between the rigid foam body and the moisture-proof lining no direct connection, but a pressure equalization space is formed, by which evaporating moisture is discharged to the outside at overpressure can be, while the direct solid connection of the hard plastic body in the perforation areas with the moisture-proof lamination ensures a firm hold of the moisture-proof lining on the rigid foam body
so Besonders vorteilhaft ist dabei eine solche Verteilung der Perforationen, daß die Bereiche beider Seitenränder der Rollbahnen von Perforationen frei bleiben. Dadurch wird erreicht, daß beim Nebeneinanderverlegen rollbarer Wärmedämmbahnen der zur Rede stehenden Art unter Verklebung des jeweils überstehenden Seitenrandes der Kaschierung der einen Rollbahn mit der Kaschierung der benachbarten Rollbahn die Kräfte beim temperaturabhängigen Zusammenziehen der Bahnen sich über die Strecke zwischen jeweils zwei benachbarten Perforationen solcher Rollbahnen ausgleichen können. Das gilt insbesondere für mit Kunststoffolien kaschierte Rollbahnen, die eine besonders starke Temperaturabhängigkeit aufweisen und bei starken Temperaturschwankungen zum Reißen neigen würden. Auch die bereits erwähnten labyrinthartigen Druckausgleichsräume zwischen den Perforationen dienen in entsprechender Weise dem Ausgleich temperaturabhängiger Spannungen in der Folienbahn.It is particularly advantageous to distribute the perforations in such a way that the areas of both side edges the runways remain free of perforations. This ensures that they can be rolled when they are laid next to one another Thermal insulation sheets of the type in question with gluing of the protruding side edge the lamination of one runway with the lamination of the adjacent runway the forces with the temperature-dependent contraction of the webs over the distance between two Can compensate for neighboring perforations of such runways. This is especially true for with Plastic sheeting laminated roller tracks, which have a particularly strong temperature dependency and at strong temperature fluctuations would tend to crack. Also the already mentioned labyrinth-like ones Pressure equalization spaces between the perforations serve to equalize in a corresponding manner temperature-dependent stresses in the film web.
