'Plattenförmiger Wärmedämmstoff'' Plate-shaped thermal insulation material nn

Die Erfindung betrifft plattenförmige Wärmedämmstoffe auf Basis von organischem Schaumkunststoff mit verminderter c mechanischer Steifigkeit in einer Vorzugsrichtung.The invention relates to plate-shaped thermal insulation materials based on organic foam plastic with reduced c mechanical rigidity in a preferred direction.

Zähharte Schaumkunststoffe, z.B. auf Basis von Polystyrol-Partikelschaum, werden in großem Maßstab zur Isolierung von Gebäudeteilen, vor allem von Dächern, gegen den Einfluß von Kälte und Wärme eingesetzt. Zähharte Schaumkunststoffe besitzen von Natur aus eine verhältnismäßig hohe Steifigkeit. Als Folge davon ist der Einbau von solchen Platten als Wärmedämmung zwischen Dachsparren viel schwieriger und zeitraubender als bei weichen Paserdämmstoffen. Da sich der Sparrenabstand je Feld und auch von Feld zu Feld meist geringfügig ändert, muß jede einzelne Platte indiv5.duell zurechtgeschnit-ten werden; eine Vorfertigung der Dämmelemente ist daher praktisch nicht möglich. Durch Schwindung oder thermische Kontraktion der steifen Schaumkunststoff-PlattenTough and hard foam plastics, e.g. based on polystyrene particle foam, are used on a large scale to insulate parts of buildings, especially roofs, against the influence of Cold and heat are used. Tough and hard foam plastics naturally have a relatively high stiffness. As a result, the installation of such panels as thermal insulation between rafters is much more difficult and time consuming than with soft Paser insulation materials. Since the Rafter spacing changes per field and also changes slightly from field to field, each individual panel must be individually cut to size will; prefabrication of the insulation elements is therefore practically impossible. By shrinkage or thermal contraction of the rigid foam plastic panels

Tbiese Aufgabe wird er fin dungs gemäß gelöst durch einen plat-*1 tenförmigen Wärmedämmstoff mit einer Dicke von 3 bis 20 cm und einer Breite von 50 bis 80 cm auf Basis von organischen Schaumkunststoffen, der dadurch gekennzeichnet ist, daß er aus einem zähharten Schaumkunststoff besteht, an den an einer oder vorzugsweise an beiden Längsseiten streifenförmige Schichten aus einem leicht verformbaren, rückfedernden Dämmstoff, beispielsweise aus einem weichelastischen Schaumkunststoff oder aus leicht verformbarem, rückfederndem Faserdämmstoff angebracht sind, welche die Dicke der Platte aufweisen und deren gesamte Breite 5 bis 30 % der Breite der Platte beträgt.This task is he fin development according to a plate * 1 ten-shaped thermal insulation material with a thickness of 3 to 20 cm and a width of 50 to 80 cm based on organic foam plastics, which is characterized in that it consists of a tough foam plastic , to which strip-shaped layers of an easily deformable, resilient insulation material, for example from a flexible foam plastic or from easily deformable, resilient fiber insulation material are attached on one or preferably on both longitudinal sides, which have the thickness of the plate and whose overall width is 5 to 30 % of the Width of the plate is.

Durch diese Maßnahme werden die Platten leicht verfornoar und das Einspannen in vorgegebene lichte Öffnungen wird wesentlich erleichtert. Die Risiken, die ein Verziehen der Holzbalken oder ein Schwinden der Schaumstoffplatte mit sich bringen, werden erheblich vermindert.By doing this, the plates are easily deformed and the clamping in given clear openings is made much easier. The risks of warping the Bring wooden beams or a shrinkage of the foam board with it, are significantly reduced.

Zähharte Schaumkunststoffe sind nach H. Götze, "Schaumkunststoff e", Straßenbau, Chemie und Technik Verlagsgesellschaft, Heidelberg, Seite 24, Schaumkörper, die mit zunehmender Druckbelastung eine stetig fortschreitende, teilweise reversible Verformung aufweisen, ohne daß ein ausgeprägter Bruch- zustand erreicht wird, wie es z.B. bei sprödharten Schaumkunststoffen der Fall ist, die bei steigender Druckbelastung ohne nennenswerte elastische Verformung durch plötzlichen Zusammenbruch des Gefüges versagen.Tough and hard foam plastics are, according to H. Götze, "Foam plastics e ", road construction, chemistry and technology publishing company, Heidelberg, page 24, foam body that increases with Pressure load show a steadily progressing, partially reversible deformation without a pronounced fracture state is achieved, as is the case with brittle, hard foam plastics, for example the case is that with increasing pressure load without any appreciable elastic deformation due to sudden Failure to collapse the structure.

Bevorzugte zähharte Schaumstoffe sind solche auf Basis von Polystyrol, insbesondere schwerentflammbar ausgerüsteter Polystyrol-Partikelschaum. Daneben sind auch extrudierter Polystyrolsehaum. Polyvinylchloridschaum und zähhart eingestellter Polyurethanschaum geeignet.
