Description

2525th

Die Erfindung betrifft eine zweilagige Kunststoffbahn, bei der zwischen zwei Folien eine Mehrzahl von zueinander parallelen Stegen angeordnet ist und die für Abdeckungen bestimmt ist, bei denen eine gekrümmte Verlegbarkeit der Kunststoffbahn, eine hohe Licht- ^o durchlässigkeit, geringes Gewicht und gute Isolierungseigenschaften bei verhältnismäßig niedrigem Preis gefordert werden.The invention relates to a two-layer plastic web, in which between two films a plurality of is arranged parallel webs and which is intended for covers in which a curved Layability of the plastic sheet, a high light ^ o permeability, low weight and good insulation properties at a relatively low price are required.

Aus dem DE-GM 19 8S780 ist eine gerippte Kunststoffbahn bekannt, die als Halbfertigfabrikat z. B. zur Herstellung von Wärmeaustauschern Verwendung finden kann. Diese Kunststoffbahn besteht aus einer im Strangpreßverfahren hergestellten, mit parallelen Längsrippen einstückig gefonnten, eine feste Form aufweisenden Bahn beispielsweise aus hochstoßfestem Polystyrol und einer auf die obere Stirnfläche der Rippen aufkaschierten Folie, die mit der stranggepreßten Bahn Kanäle bildet.From DE-GM 19 8S780 is a ribbed one Plastic sheet known as a semi-finished product z. B. for the production of heat exchangers use Can be found. This plastic sheet consists of one produced by extrusion, with parallel Longitudinal ribs formed in one piece and having a solid shape, for example made of high impact-resistant material Polystyrene and a film laminated to the upper face of the ribs, which is extruded with the Rail forms channels.

Bahnen dieser verhältnismäßig starre Fertigerzeugnisse bildenden Art sind für Zwecke, für die die erfindungsgemäße Bahn bestimmt ist, z. B. zur Bildung einer gekrümmte Flächen aufweisenden Abdeckung von Gewächshäusern und Schwimmbecken, zum Bau von Zelten und als Planen zur Abdeckung von Lastkraftwagen, nicht geeignet.Tracks of this type of relatively rigid finished products are used for purposes for which the web according to the invention is intended, for. B. to form a curved surface having cover of greenhouses and swimming pools, for building tents and as tarpaulins for covering Truck, not suitable.

Ein Verfahren zur Herstellung solcher zum Bau von Wärmetauschern geeigneter Bahnen, bei denen zum Zweck der besseren Haftung der auf die im Strangpreßverfahren hergestellte, mit parallelen Längsrippen einstückig geformte Bahn aufkaschierten Folie die obere Stirnfläche der Stege flanschartig verbreitert wird, ist in der GB-PS 12 98 858 derselben Firma beschrieben. Bei den nach diesem Verfahren hergestellten Bahnen bestehen die Rippen, die auch in sich kreuzender Anordnung vorgesehen sein können, ebenso wie die Folien aus biegsamem Material, so daß die Bahnen in keiner Richtung eine Eigensieifigkeit besitzen.A process for the production of such webs suitable for the construction of heat exchangers, in which the Purpose of better adhesion to the extrusion-molded, with parallel longitudinal ribs one-piece formed web laminated film widened the upper end face of the webs like a flange is described in GB-PS 12 98 858 of the same company. In the case of those produced by this process The ribs, which can also be provided in an intersecting arrangement, also exist like the foils made of flexible material, so that the tracks are not intrinsic in any direction own.

Der Erfindung liegt die Aufgabe zugrunde, eine zweilagige, für Abdeckungen der eingangs genannten Art bestimmte Kunststoffbahn bei gegenüber der Herstellung von ein Kasten- oder Hohlprofil aufweisenden Bahnen geringeren Fertigungskosten so auszubilden, daß sie auf seitlichen Stützen aufliegend, jeder durch eine Trägerkonstruktion vorgegebenen Krümmung angepaßt eine steife Überdachung eines Raumes ohne Durchhang bildet, jedoch bei Nichtgebrauch oder zu Zwecken des Versandes aufgerollt werden kann.The invention is based on the object of a two-layer, for covers of the aforementioned Type of certain plastic sheet when compared to the production of a box or hollow profile having Train lanes lower manufacturing costs so that they rest on side supports, each A rigid roofing of a room is adapted to the curvature given by a support structure forms without slack, but can be rolled up when not in use or for shipping purposes.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Stege der Kunststoffbahn biegesteif und die beiden Folien biegeschlaff sind. Zur Erhöhung der Steifigkeit der Stege und um eine sichere Verschweißung oder Verklebung der Stege mit den Folien zu gewährleisten, können die biegesteifen Stege ein L-, T-, I-, U- oder ein Kasten-Profil aufweisen.This object is achieved according to the invention in that the webs of the plastic web are rigid and rigid the two foils are limp. To increase the rigidity of the webs and to ensure a secure weld or to ensure that the bars are glued to the foils, the rigid bars can have an L, T, Have I, U or a box profile.

Um zwei Bahnen dieser Art, gegebenenfalls am Ort ihrer Vorwendung, in einfacher Weise miteinander verbinden zu können, können die beiden randseitigen Stsge randoffene Aussparungen aufweisen, die Verankerungsorganen einer Trägerkonstruktion als Rasten dienen. Zur gegenseitigen Verhakung der randseitigen Stege zweier miteinander zu verbindender Kunststoffbahnen kann an die randseitigen Stege ein U-Profil mit ungleich langen Schenkeln angeformt sein.To two orbits of this kind, if necessary on site their use to be able to connect with each other in a simple manner, the two edge-side Stsge have open-edged recesses, the anchoring organs of a support structure as notches to serve. For interlocking the edge webs of two plastic webs to be connected to one another A U-profile with legs of unequal length can be formed on the edge-side webs.

In dfer Zeichnung sind Ausführungsbeispiele der erfindungsgemäßen Kunststoffbahn und die Art ihrer gegenseitigen Verbindung in schematischer Weise dargestellt. Es zeigtIn the drawing are exemplary embodiments of the plastic web according to the invention and the nature of their mutual connection shown in a schematic manner. It shows

F i g. 1 einen Ausschnitt aus zwei Kunststoffbahnen mit durch biegesteife, ein I-Profil aufweisende Stege 1 verbundenen biegeschlaffen Folien 2, an deren randseitigen Stegen 3, 3' ein U-Profil, mit ungleich langen Schenkeln angeformt ist,F i g. 1 shows a section of two plastic webs with webs 1 that are rigid and have an I-profile connected pliable films 2, on the edge webs 3, 3 'of a U-profile, with unequal length Thighs is molded,

F i g. 2 die Verbindung zweier Kunststoffbahnen, bei deren einer die biegeschlaffen Folien 2 über einen Steg 1 überstehende Enden aufweisen, die auf die Folien 2 der anderen Kunststoffbahn im Bereich eines Steges 1 aufgeschweißt sind,F i g. 2 the connection of two plastic webs, one of which has the pliable films 2 via a web 1 have protruding ends which are attached to the foils 2 of the other plastic web in the area of a web 1 are welded on,

F i g. 3 die Verbindung zweier Kunststoffbahnen, in deren randseitige, ein I-Profil aufweisende Stege ein Verankerungsorgan 4 in Gestalt eines Hohlprofils eingesetzt ist, und deren sich überlappende Folienenden miteinander verschweißt sind.F i g. 3 the connection of two plastic sheets, in their edge-side, an I-profile having webs Anchoring member 4 is used in the form of a hollow profile, and the overlapping film ends are welded together.
