Abstract

Building element controlling transmission of direct solar heat and light comprises >=2 light-permeable panes combined with similarly light-permeable connecting bridges to form a box, designed so that side exposed to the sun does not permit sunlight to penetrate. This is achieved by installing in the interior of the box opaque slats which extend diagonally across the box and 1 of whose surfaces faces the sun. The opaque slats consist of white or light-coloured, glass-fibre-reinforced polyester resin. They are 1 mm thick. Alternatively, they may consist of a translucent material or have reflective surfaces. Installed in roofs as skylights, or in walls of buildings. Permits transmission of light of acceptable frequencies whilst excluding direct transmission of solar heat.

Description

Lamelle zur Steuerung der Licht- und Wärmetransmission von doppelschaligen Lichtelementen für Dach und Wand Die Neuerung bezieht sich auf unbewegliche, starr eingebaute Lamellen in einem doppeischaligen Lichtelement, die eine bedarfsorientierte Steuerung der Tageslichttransmission und gleichzeitig eine Unterbindung der unerwünschten, direkten Wärmeeinstrahlung durch Sonnenenergie ermöglicht.Lamella to control the light and heat transmission of double-shell Light elements for roof and wall The innovation relates to immovable, rigid built-in slats in a double-shell light element, which provides a demand-oriented Control of the daylight transmission and at the same time a prevention of the undesired, allows direct heat radiation through solar energy.

Es sind doppelschalige Lichtelemente bekannt, bei denen auf der zur Sonne ausgerichteten Seite z.B. Glasgespinste eingelegt werden, die eine Reduzierung der direkten Licht- und Wrmeeinstrahlung bewirkens Dadurch ergibt sich der Nachteil, daß der unerwünschte Effekt der direkten Einstrahlung von Sonnenlicht- und Sonnenwärmeenergie in das Halleninnere zwar reduziert, nicht aber ausgeschaltet wird.There are double-shell light elements known in which on the for Sun-facing side, for example, fiberglass can be inserted, which reduces cause direct light and heat radiation This has the disadvantage, that the undesirable effect of direct exposure to sunlight and solar thermal energy inside the hall is reduced, but not switched off.

Ferner sind Systeme bekannt, die auf der zur Sonne ausgerichteten Seite völlig lichtundurchlässig sind und dadurch die unerwUnschte direkte Wärmeeinstrahlung unterbinden wit dem Nachteil, daß auch keine - zur Belichtung einer Halle durch Tageslicht benötigte -Lichttransmission erfolgt.Furthermore, systems are known that are oriented towards the sun Side are completely opaque and thus the undesired direct heat radiation prevent wit the disadvantage that no - to illuminate a hall through Daylight required -light transmission takes place.

Aufgabe der Erfindung ist es, ein doppelschaliges Belichtungselement zu schaffen, bei dem ein Höchstmaß an qualitativ hochwertiger LichttranisOion ohne nachteilige direkte Wärmeinstrahlung qewährleistet ist.The object of the invention is to provide a double-shell exposure element to create a maximum of high-quality light transiOnion without disadvantageous direct heat radiation is guaranteed.

Die Lösung der vorgenannten Aufgabe zeichnet sich gemäß der Erfindung dadurch aus, daß bei einem Lichtelement mit mindestens zwei tbereinander angeordneten, lichtdurchlässigen Scheiben mit ebenfalls lichtdurchlässigen Verbindungsstegen (= Hohlkammersystem) diagonal in die Hohlkammern eingeschobene, lichtundurchlässige Lamellen angeordnet werden. Die lichtundurchlässigen Lamellen bestehen vorteilhaft aus weißem bzw. hellem Material, z.B. aus ca. 1 mm dickem, glasfaserverstärkten ungesättigten Polyesterharz (GF - UP>.The solution to the aforementioned problem is distinguished according to the invention characterized in that, in the case of a light element with at least two one above the other, translucent panes with also translucent connecting webs (= Hollow chamber system), opaque ones inserted diagonally into the hollow chambers Slats are arranged. The opaque slats are advantageous made of white or light material, e.g. from approx. 1 mm thick, glass fiber reinforced unsaturated polyester resin (GF - UP>.

Die Befestigung der diagonal in den Hohlkammern angeordneten Lamellen kann wahlweise mittels Klemmverbindung, Klebeverbindung, Schraubverbindung o.ä. erfolgen.The fastening of the slats arranged diagonally in the hollow chambers can optionally be made by means of a clamp connection, adhesive connection, screw connection or similar. take place.

Im eingebauten Zustand soll eine Flächenseite der Lamellen zur Sonnenseite (den) zeigen. Durch eine solche Anordnung ergeben sich wesentliche klimatechnische Vorteile für die Halle. Es wird verhindert, daß schlechte Lichtqualität und unerwünschte Hallenaufheizung durch direkte Sonneneinstrahlung eintritt.When installed, one surface side of the slats should face the sunny side show. Such an arrangement results in essential air conditioning Advantages for the hall. It prevents poor quality and undesirable light Hall heating occurs through direct sunlight.

In den FIG. 2,3,4,5 ist zeichnerisch dargestellt, daß durch die Neuerung die direkten Sonnenlicht- und Sonnenwärmestrahlen auf die diagonal angeordneten, lichtundurchlässigen Lamellen treffen. Die unerwünschte Wärmeenergie wird z.T. reflektiert, z.T. absorbiert und am unmittelbaren Durchgang in das Halleninnere gehindert. Die Sonnenliahtstrahlen werden auf den Lamellen gebrochen und die gebrochenen Lichtstrahlen tragen - als ErgSnsung zum unmittelbar durchgehenden Nordlicht - sur weitgehend gleichmäßigen Ausleuchtung der Halle mit qualitativ hochwertiges Tageslicht beS.In FIGS. 2,3,4,5 is graphically shown that by the innovation direct sunlight and solar heat rays on the diagonally arranged, meet opaque slats. The unwanted heat energy is partly reflected, partly absorbed and prevented from direct passage into the hall interior. the Sun rays are refracted on the slats and the refracted rays of light carry - as a complement to the immediately continuous northern lights - sur largely uniform illumination of the hall with high quality daylight beS.

In FIG. 1 ist zeichnerisch dargestellt, wie die Lamellen in eine handelsübliche PLEXIGLAS XT - Stegdoppelplatte angeordnet werden. Die mit tels lichtdurchlässiger Stege (1> verbundenen lichtdurchlässigen Scheiben (2) bilden mehrere, lichtdurchlässige Hohlkammern nebeneinander.In FIG. 1 is graphically shown how the slats in a commercially available PLEXIGLAS XT double-skin sheet. The means of translucent Bars (1> connected translucent panes (2) form several translucent ones Hollow chambers next to each other.

Die in diesem Beispiel cal So mm breiten und ca. 1 mm dicken lichtundurchlässigen Lamellen (3) werden derart in die Hohlkammern eingeschoben, daß bei einem Sonneneinstrahlungswinkel von max. 600 in Mitteleuropa die direkten Sonnenstrahlen immer auf die Lamellenflächen auftreffen müssen.In this example, cal So mm wide and approx. 1 mm thick opaque Lamellae (3) are pushed into the hollow chambers in such a way that at an angle of sunlight From a maximum of 600 in Central Europe, the direct rays of the sun always hit the slat surfaces have to hit.

Mit bekannten Profilsystemen (4) und Dichtungsmaterialien (5) werden die mit Lamellen ausgestatteten Lichtelemente mit dem Baukörper verbunden.With known profile systems (4) and sealing materials (5) the light elements equipped with slats are connected to the structure.
