Abstract

Heat-insulating, transparent building element which may be used in mfr. of skylights, double glazing and the like, comprises a wooden, plastics or metal frame (which may be square-shaped, rectangular, circular or curved, i.e. non-planar, and has some commercially available plastics sheet, pref. a PVC sheet, stretched over it on both sides. Thickness of the frame depends on the intended use of the prod. The frame doubles as spacer between the sheets and may be reinforced with suitably placed ribs to render it dimensionally stable. The plastics sheets are transparent, translucent or opaque, as required, one of them (pref. that exposed to the environment) being stronger i.e thicker, than the other. If the intended use of the prod. allows then a piece of plywood may be usbstd. for the frame. Instead of the 2 plastics sheets a plastics bag that fits over the frame (or plywood) may be used. After it has been fitted its open side is then weld-sealed by hand or machine.

Description

SEZE 1 OHNUNG : Wärmeisolierendes und lichtdurchlässiges BauelementSEZE 1 OHNUNG: Thermally insulating and translucent building element

Die Erfindung betrifft die Herstellung doppelseitig mit Kunststoffolie bespannter Holz-, Metall- und Kunststoffrahmen, die als Bauelemente in Form von Wand -elementen, Tür- und Fensterelementen sowie Dachelementen zu verwenden sind, wobei die Doppelbespannung mit Kunststoffolie insbesondere wärmedämmend, also energiesparend, wirkt. Je nach Beschichtung der Kunststoffolie kann auch der entgegengesetzte Effekt, nämlich eine wärmeabstoßende Wirkung erreicht werden.The invention relates to the production of double-sided plastic film Covered wood, metal and plastic frames, which are used as structural elements in the form of Wall elements, door and window elements as well as roof elements are to be used, whereby the double covering with plastic film is particularly heat-insulating, i.e. energy-saving, works. Depending on the coating of the plastic film, the opposite effect, namely, a heat-repelling effect can be achieved.

Es wird mit der Erfindung der gleiche Effekt erzielt wie bei einer aufwendigen Doppelverglasung, wobei die vom Verbraucher aufzuwendenden Kosten nur einen Bruchteil der vorstehend aufgeführten traditionellen Verglasung betragen. Erfindungsgemäß wird davon ausgegangen, daß über einen, in beliebiger Größe und Form zu erstellenden Rahmen aus Holz, Kunststoff oder Metall beidseitig eine Folie so straff gespannt wird, daß sie den sogenannten Trommelfelleffekt erreicht. Dieser Spannungseffekt wird durch verschiedene Anwendungsarten und Verarbei tungsmethoden erzielt : 1. Verwendung von Folien, insbesondere von sogenannten Schrumpffolien, die unter Hitzeeinwirkung verspannt werden und sich nach Abkühlung enorm straffen, 2. Verwendung von sogenannten Stretchfolien, PVC-Folien mit hohem Ausdehnurgskoeffizienten, dadurch gekennzeichnet, daß sie nach der Spannung ähnlich wie Gummi die ursprüngliche Form zurückzugewinnen suchen und somit den Spannungseffekt perfekt machen.The same effect is achieved with the invention as with one elaborate double glazing, with the costs incurred by the consumer only a fraction of the traditional glazing listed above. According to the invention it is assumed that one, in any size and Form to be created frame made of wood, plastic or metal on both sides a film is stretched so tight that it achieves the so-called eardrum effect. This The tension effect is created by various types of application and processing methods achieved: 1. Use of films, especially so-called shrink films, which are tense under the influence of heat and tighten enormously after cooling, 2. Use of so-called stretch films, PVC films with a high expansion coefficient, characterized in that it is similar to the original rubber after the tension Seeking to regain shape and thus perfect the tension effect.

Erfindungsgemäß wird auch an die Herstellung von Foliensäcken gedacht, in welche die gefertigten Rahmen eingeschoben werden und das offene Ende im Moment der optimalen Spannung durch Hitzeeinwirkung oder im Stretchverfahren entweder von Hand oder maschinell verschweißt wird.According to the invention, the production of film sacks is also contemplated, into which the manufactured frames are inserted and the open end at the moment the optimal tension through the action of heat or in the stretching process either from Hand or machine welded.

Erfindungsmäßig ist weiterhin vorgesehen, daß Rahmenelemente kleiner Größenordnung als Glasscheibenersatz und diejenigen größerer Größenordnung als Wand- und Dachelemente verwendet werden, wobei entsprechend der Belastungsnotwendigkeit der Rahmen zusätzlich mit Querverstrebungen und/oder durch zusätzliche Dicke des Materials verstärkt werden kann.According to the invention it is also provided that frame elements are smaller As a replacement for glass panes and those of a larger size than wall and roof elements are used, depending on the load requirement the frame additionally with cross bracing and / or by additional thickness of the Material can be reinforced.

Die Bauelemente aus-Rahmen mit doppelseitig bespannter Kunststoffolie sind insbesondere als Bauelemente von Sporthallen, 5 chwi mmb adhal len, Lagerräumen, Gewächshäusern und überall dort geeignet, wo bisher Folien nur als Witterungsschutz dienten. Die wärmeisolierende Wirkung der Doppelbespannung ist insbesondere im Hinblick auf die neuen Verordnungen des Wärmeschutzes und der Energieersparnis interessant.The components made of frames with plastic film covered on both sides are particularly suitable as components of sports halls, 5 chwi mmb adhal len, storage rooms, Suitable for greenhouses and wherever foils were previously only used as protection against the weather served. The heat insulating effect of the double covering is particularly important interesting on the new regulations of thermal protection and energy saving.

Ein weiterer zu erzielender Effekt des Bauelements ist die Kombination von verschiedenen Folien auf der Ober- und Unterseite, um damit einen Effekt zu erzielen, wie er bei Solarkollektoren bekannt ist.Another effect to be achieved by the component is the combination of different foils on the top and bottom to create an effect as it is known from solar collectors.

Je nach gewünschtem Zweck wird dadurch die Sonnenenergie absorbiert und die entstehende Wärme genutzt oder reflektiert, um den Innenraum kühl zu halten.Depending on the desired purpose, the solar energy is absorbed in this way and the resulting heat is used or reflected to keep the interior cool.

Die Reflektion kann so gestaltet werden, daß sie gezielt, z.B. auf den Boden gerichtet wird und damit das Pflanzenwachstum gefördert wird, indem der Boden aufgewärmt wird, um diese Wärme-nachts an die Pflanzen wieder abzustrahlen Ein weiterer Vorteil der Erfindung liegt darin, daß die Bauelemente entgegen der üblichen Doppelverglasung ein geringes Gewicht aufweisen und damit einen schnellen Auf- und Abbau gewährleisten. Es empfiehlt sich, die Bauelemente in ein Gerüstskelett einzuschieben, welches aus im Querschnitt doppel-U-förmigen Trägern, aus Metall, Kunststoff, Holz usw. besteht. Die aufeinandertreffenden Bauelemente werden untereinander verbunden.The reflection can be designed so that it is targeted, e.g. on the soil is straightened and thus plant growth is promoted by the Soil is warmed up in order to radiate this heat back to the plants at night Another advantage of the invention is that the components contrary to conventional double glazing are lightweight and therefore quick Ensure assembly and dismantling. It is advisable to put the building elements in a framework insert which from in cross section double U-shaped beams, made of metal, plastic, wood, etc. The meeting elements are connected to each other.

Die schnelle Auf-und Abbaubarkeit, die Bruchsicherheit und Preisgünstigkeit der Bauelemente macht die Verwendbarkeit der Bauelemente, insbesondere für Bauten interessant, die nicht ortsgebunden, also transportabel, erstellt werden sollen, z.B. Gewächshäuser, Lagerstätten etc. Eine ebenfalls vorzugsweise Verwendung dürften die Bauelemente auch bei sogenannten Saisonhallen finden wie z.B. Bootshallen und Tennishallen im Winter, die im Sommer wieder abgebaut werden, weil sie beim Sommerbetrieb stören.The quick assembly and dismantling, the break resistance and low cost of the components makes the components usable, especially for buildings interesting, which should not be fixed to a specific location, i.e. transportable, E.g. greenhouses, storage facilities, etc. Also a preferred use the components can also be found in so-called seasonal halls such as boat halls and Tennis halls in winter, which are dismantled again in summer because they are in operation in summer disturb.
