Description

Die Erfindung betrifft eine Zarge zum Anschluß eines eine Dachöffnung abdeckenden vorzugsweise ebenen Bauteils, die als Aufkantung einen allseitigen Abschluß der Dachöffnung bildet und an der vom Dach abgewandten Seite zur Aufnahme eines Befestigungselementes für ein die Dachöffnung ab­deckendes Bauteil und dessen andere Seite zur Befestigung an oder auf dem Dach ausgebildet ist. Zargen sind im Hochbau erforderliche Bauelemente um z.B. Oberlichte oder Ausstiegsöffnungen, deren Anschlußebene über die wasserführende Schicht des Dachaufbaues herausge­hoben werden muß. Sie sind in verschiedenen Ausführungen be­kannt, z.B. als Stahlblechzarge für den Einbau einer Shed­verglasung auf Massivdecken. Derartige Stahlblechzargen be­stehen aus einem Fußprofil zum Anschluß der Tragkonstruktion der Shedverglasung, einem Stückwinkel und einem Verkleidungs­blech, wobei eine Wärmedämmung aufgebracht sein kann, die über Dachfolien mittels einer metallischen Klemmleiste gehalten wird. Eine derartige Zarge ist in der Druckschrift "Shed­licht-Planungsmappe" der Firma Eberspächer, Seite 9, Aus­ gabe Mai 1986 beschrieben. Weitere Beispiele von bekannten Zargen sind in der Druckschrift "Toplicht von Eberspächer", Seiten 14/15, Ausgabe März 1986 beschrieben. In dieser Druck­schrift ist als Abbildung (C), Seite 14, eine nicht frei­tragende Stahlzarge auf Beton mit einer eingelegten Holzbohle und einemder Isolierung dienenden Luftraum dargestellt, bei welcher die Horizontalkräfte auf die Zarge und die Vertikal­kräfte auf die Dachkonstruktion übertragen werden. Die Dach­haut ist bei dieser bekannten Zarge mit der Holzbohle ver­nagelt. Den oberen Abschluß bei dieser Zarge bildet ein die Holzbohle überragendes Winkelstück,mit dem ein Eindringen von Wasser und Schmutz hinter die Dachhaut verhindert werden soll. Die Dachhaut (Bitumenbahn oder Folie) ist über einen Keil an die Bohle herangeführt.The invention relates to a frame for connecting a roof opening covering preferably flat component, which forms an all-round termination of the roof opening as a backsplash and on the side facing away from the roof for receiving a fastening element for a component covering the roof opening and its other side for attachment to or on the roof is formed. Frames are required in building construction, for example skylights or exit openings, the connection level of which has to be lifted out over the water-bearing layer of the roof structure. They are known in different versions, for example as a sheet steel frame for installing shed glazing on solid ceilings. Such steel sheet frames consist of a foot profile for connecting the supporting structure of the shed glazing, a piece angle and a cladding panel, wherein thermal insulation can be applied, which is held over roof foils by means of a metallic terminal strip. Such a frame is in the publication "Shedlicht planning folder" from Eberspächer, page 9, Aus described in May 1986. Further examples of known frames are described in the publication "Toplicht von Eberspächer", pages 14/15, March 1986 edition. In this publication, as illustration (C), page 14, a non-self-supporting steel frame on concrete is shown with an inserted wooden plank and an air space used for insulation, in which the horizontal forces are transferred to the frame and the vertical forces to the roof structure. The roof skin is nailed to the wooden plank in this known frame. The upper end of this frame is formed by a corner piece that overhangs the wooden plank and is intended to prevent water and dirt from penetrating behind the roof skin. The roof skin (bitumen sheet or foil) is brought to the screed using a wedge.

Die bekannten Zargen haben den Nachteil, daß sie unverhältnis­mäßig schwer sind und daher eine starke Unterkonstruktion ver­langen. Auch die Ausbildung der Wärmeisolation als Leerraum zwischen der in den Zargenrahmen eingesetzten Holzbohle und dem Rahmen verlangt infolge der parallelen Anordnung von Bohle und Leerraum einen großen Raum, da ein Mindestmaß für den Leerraum nicht unterschritten werden darf, wenn eine auch nur annähernd ausreichende Isolierung erreicht werden soll.The known frames have the disadvantage that they are disproportionately heavy and therefore require a strong substructure. The design of the thermal insulation as an empty space between the wooden plank inserted in the frame and the frame requires a large space due to the parallel arrangement of the screed and empty space, since a minimum dimension for the empty space must not be undercut if even nearly sufficient insulation is achieved should.

Der Erfindung liegt die Aufgabe zugrunde eine besonders leichte und ästhetisch ansprechende, leicht herzustellende Zarge mit guter Wärmeisolierung aufzuzeigen, bei welcher Anschlußbahnen oder Folien einfach und dichtend anschließbar sind.The invention has for its object to show a particularly light and aesthetically pleasing, easy to manufacture frame with good thermal insulation, in which connecting tracks or films can be easily and sealingly connected.

Diese Aufgabe wird bei einer gattungsgemäßen Zarge dadurch gelöst, daß die Zarge aus einem an der der Dachöffnung abgewandten Seite teilweise offenen Dünnblechrahmen besteht und mit einem wärme­isolierenden Stoff gefüllt ist und an ihrem oberen Ende auf der Außenseite einen Ansatz aufweist, dessen untere Begrenzungs­fläche schräg nach innen verjüngt ist, und daß an diesem An­satz ein Winkelblech befestigt ist, dessen einer Schenkel mit der verjüngten Fläche des Ansatzes und dessen anderer Schenkel mit dem senkrechten Teil der Zarge verbunden ist, und daß ferner die Zarge zu ihrem Anschluß an das Dach ein aus Blech gebildetes Anschlußstück aufweist.This object is achieved in a generic frame in that the frame consists of a thin sheet metal frame partially open on the side facing away from the roof opening and is filled with a heat-insulating material and at its upper end on the Outside has an approach, the lower boundary surface is tapered obliquely inwards, and that an angle plate is attached to this approach, one leg is connected to the tapered surface of the approach and the other leg to the vertical part of the frame, and that also Frame for its connection to the roof has a connector made of sheet metal.

Dabei ist es leicht und ohne größeren Aufwand möglich, in den wärmeisolierenden Stoff einen festen, ggf. auch tragenden Kern einzubringen, so daß diese Zarge auch als selbsttragende Zarge verwendet werden kann. Dieses ist bei einer weiter­führenden Ausgestaltung der Erfindung besonders einfach, bei welcher als wärmeisolierender Stoff ein Kunststoffschaum zur Dünnblechaussteifung in den Dünnblechrahmen eingeschäumt wird und daß sowohl das Winkelblech als auch das Anschlußstück und ggf. ein weiteres Anschlußstück eingeschäumt ist. Dabei können gemäß einer weiteren Ausgestaltung der Erfindung das Winkel­stück und die Anschlußstücke eine Kunststoffauflage aufweisen. An der gemäß der Erfindung ausgebildeten Zarge kann das weitere Anschlußstück, das an der der Lichtöffnung abgewandten Seite der Zarge eingeschäumt ist, in einem von einer evtl. Dachauflage aus Wärmeisoliermaterial bestimmten Abstand angebracht sein, so daß eine auf dieser Isolierschicht aufliegende Dachbahn oder Folie bis an die Zarge herangeführt, dort mit dem Anschluß folien­verschweißt und dann an der Zarge hochgezogen und an dem Winkel­stück ebenfalls folienverschweißt werden. Diese gemäß der Er­findung durch die Kunststoffbeschichtung des Winkelstückes und der Anschlußstücke erstmals mögliche Folienverschweißung von An­schlußbahnen hat den besonderen Vorteil einer unbedingten Staub­und Wasserdichtheit. Durch das weitere, in vorgegebener Distanz zum Dach angeordnete Anschlußstück, wird, wie oben beschrieben, ermöglicht, die Dachhaut, insbesondere bei Foliendächer, bis un­ mittelbar an die Zarge heranzuführen und bereits dort zu ver­kleben, so daß auftretende Zugkräfte die weiterhin an der Zarge hochgezogene Folie nicht abreißen können.It is easily and without great effort possible to introduce a solid, possibly also load-bearing core into the heat-insulating material, so that this frame can also be used as a self-supporting frame. This is particularly simple in a further embodiment of the invention, in which a plastic foam for thin sheet reinforcement is foamed into the thin sheet frame as a heat-insulating material and that both the angle sheet and the connecting piece and possibly a further connecting piece are foamed in. According to a further embodiment of the invention, the angle piece and the connection pieces can have a plastic pad. On the frame designed according to the invention, the further connection piece, which is foamed on the side of the frame facing away from the light opening, can be attached at a certain distance from a possible roof support made of heat insulating material, so that a roofing membrane or film resting on this insulating layer is up to the frame is brought up, there foil-welded to the connection and then pulled up on the frame and also foil-sealed on the elbow. This, according to the invention, for the first time possible film welding of connecting tracks by the plastic coating of the angle piece and the connecting pieces has the particular advantage of an absolute dust and water tightness. The further, arranged at a predetermined distance from the roof connector, as described above, enables the roof skin, in particular in the case of film roofs, to un indirectly lead to the frame and glue there already, so that tensile forces cannot tear off the film still pulled up on the frame.

Weitere Ausgestaltungen werden anhand der Figur aufgezeigt. In dieser Figur ist ein Ausführungsbeispiel vereinfacht und schema­tisch dargestellt, und zwar bei einer Toplichtzarge für eine Ab­deckung durch eine Stegdoppelplatte als Lichtelement. Bei der­artigen Ausführungen muß an mindestens zwei parallel zueinander-­liegenden Seiten einer abzudeckenden Lichtöffnung 1, die auch dem Rauch- und Wärmeabzug dienen kann, eine Zarge 2 angeordnet sein, auf der über ein Halteelement 3 die Abdeckung 4 im Bei­spiel eine Stegdoppelplatte befestigt ist. Diese Abdeckung 4 kann natürlich auch schwenkbar angeordnet sein, so daß zur Be­lüftung oder im Falle eines erforderlichen Rauch- und/oder Wärme­abzuges eine Schnellöffnung über geeignete Öffnungsmechanismen erfolgen kann. Das Halteelement 3 ist auf dem Dünnblechrahmen 5 der Zarge 2 mit seinem waagrechten Schenkel 3b befestigt, sein senkrechter Schenkel 3a bestimmt den erforderlichen Abstand der durch Schrauben 6 auf einem abgewinkelten Schenkel 3c be­festigten Stegdoppelplatte 4, eine eingelegte Dichtung 3d ver­hindert das Eindringen von Staub oder Wasser in den Innenraum. Die erfindungsgemäße Zarge 2 besteht aus einem Dünnblechrahmen 5 von im Beispiel 0,75 bis 1 mm Stärke, wobei dieser Dünnblech­rahmen 5 an der der Lichtöffnung 1 abgewandten Seite offen ist und als Rahmen zur Aufnahme eines wärmeisolierenden Stoffes 7 dient. Dieser kann als Polyurethanschaum eingeschäumt sein, aber auch aus einem festen, tragfähigen Material bestehen, auch kann ein fester Kern, z.B. ein als Stütze und damit lastübertragend ausgebildeter Holzteil in dem Schaum angeordnet sein (in der Fig. nicht dargestellt). Die Zarge 2 weist an ihrem oberen, d.h. dem Dach abgewandten Ende einen Ansatz 8 auf, dessen untere Kante sich nach innen verjüngend ausgebildet ist. Durch diesen der­gestalt ausgebildeten Ansatz wird erreicht, daß eine an dem senk­rechten Teil 9 der Zarge 2 hochgezogene Dachbahn oder Folie 10 regensicher in dem von dem Ansatz 8 gebildeten Winkel enden kann. Der Dünnblechrahmen 5 ist an dem Ansatz 8 bis in den nach innen verjüngten Abschnitt geführt und endet dort. Ein Winkelblech 11 mit einem senkrechten Winkel 11a, einem entsprechend der Ver­jüngung des Ansatzes 8 abgewinkelten Schenkel 11b und einem an dem senkrechten Schenkel 11a sich waagrecht anschließenden Schenkel 11c ist derart an dem Ansatz 8 angesetzt, daß es eine Befestigungsfläche für die Dachhaut oder Folie 10 bildet, dabei ist der waagrechte Schenkel 11c in dem PU-Schaum eingeschäumt. Zur besseren Verbindung kann dabei dieser Schenkel Ausnehmungen aufweisen. Das Winkelblech 11 ist vorzugsweise Kunststoff, so daß die Dachhaut oder Folie leicht folienverschweißt werden kann, d.h. es wird vor dem Aufbringen der Folie ein Lösungsmittel auf­getragen, so daß eine absolut dichte und feste Verbindung zwischen Winkelblech 11 und Folie 10 entsteht. Damit entfällt das bisher übliche Verschrauben oder Einklemmen der Dachhaut.Further configurations are shown with the aid of the figure. In this figure, an exemplary embodiment is shown in a simplified and schematic manner, specifically in the case of a top light frame for a cover by means of a double-wall sheet as a light element. In such designs, a frame 2 must be arranged on at least two mutually parallel sides of a light opening 1 to be covered, which can also be used for smoke and heat extraction, on which the cover 4 in the example, a double web plate is fastened via a holding element 3. This cover 4 can, of course, also be arranged pivotably, so that quick opening can take place via suitable opening mechanisms for ventilation or in the event of a necessary smoke and / or heat extraction. The holding element 3 is fastened on the thin sheet metal frame 5 of the frame 2 with its horizontal leg 3b, its vertical leg 3a determines the required distance of the web double plate 4 fastened by screws 6 on an angled leg 3c, an inserted seal 3d prevents the ingress of dust or water in the interior. The frame 2 according to the invention consists of a thin sheet metal frame 5 with a thickness of 0.75 to 1 mm in the example, this thin sheet metal frame 5 being open on the side facing away from the light opening 1 and serving as a frame for receiving a heat-insulating material 7. This can be foamed in as a polyurethane foam, but can also consist of a solid, load-bearing material, and a solid core, for example a wooden part designed as a support and thus load-transmitting, can also be arranged in the foam (not shown in the figure). The frame 2 has at its upper end, ie the end facing away from the roof, a shoulder 8, the lower edge of which is tapered inwards. This approach designed in this way ensures that a roof membrane or film 10 drawn up on the vertical part 9 of the frame 2 can end in a rainproof manner at the angle formed by the approach 8. The thin sheet metal frame 5 is guided on the neck 8 into the inwardly tapered section and ends there. An angle plate 11 with a vertical angle 11a, a leg 11b angled in accordance with the tapering of the projection 8 and a leg 11c horizontally adjoining the vertical leg 11a is attached to the extension 8 in such a way that it forms a fastening surface for the roof skin or film 10 , the horizontal leg 11c is foamed in the PU foam. For better connection, this leg can have recesses. The angle plate 11 is preferably plastic, so that the roof skin or film can be easily film-welded, ie a solvent is applied before the film is applied, so that an absolutely tight and firm connection between the angle plate 11 and the film 10 is produced. This eliminates the usual screwing or clamping of the roof skin.

An dem unteren Ende der Zarge 2, d.h. an dem Ende mit dem die Zarge 2 auf das Dach 12 aufgesetzt und mit ihm verbunden wird, ist der Dünnblechrahmen 5 über den ausgeschäumten Teil ver­längert, so daß ein Befestigungsschenkel 13 entsteht, über den die Befestigung auf dem Dach 12 erfolgt, z.B. in bekannter Weise durch Verschraubung. Natürlich kann die Zarge 2 durch ent­sprechende Formgebung des Dünnblechrahmens 5 auch innerhalb der Lichtöffnung 1, diese begrenzend, angeordnet sein.At the lower end of the frame 2, i.e. at the end with which the frame 2 is placed on the roof 12 and connected to it, the thin sheet metal frame 5 is extended over the foamed part, so that a fastening leg 13 is formed, via which the fastening on the roof 12 takes place, e.g. in a known manner by screwing. Of course, the frame 2 can also be arranged within the light opening 1, by delimiting it, by shaping the thin sheet metal frame 5 accordingly.

An dem unteren Ende der Zarge 2 ist außerdem an der der Licht­öffnung abgewandten Seite ein Anschlußstück 14, mit einem senk­rechten Schenkel 14a, einem in den PU-Schaum eingeschäumten Schenkel 14b und einem von der Zarge 2 abweisenden Schenkel 14c angeordnet, von dem die Schenkel 14a und 14c ebenfalls kunst­stoffbeschichtet sind, zum Anschluß einer Dachisolierfolie 15, die in beschriebener Weise folienverschweißt ist. Die Befesti­gung an dem Dach 12 kann auch durch den Schenkel 14c samt dem Schenkel 13 des Dünnblechrahmens 5 erfolgen. Auf diesem An­schlußteil 14 liegt die Dachisolierung 16 auf, die bis an die Zarge 2 herangeführt ist. Auf der gleichen Seite der Zarge 2 ist ein weiteres Anschlußstück 16, das U-förmig ausgebildet ist, eingeschäumt und ebenfalls kunststoffbeschichtet zum Anschluß der hochgezogenen Dachisolierfolie 15, falls diese die Dachisolierung 16 überragend ausgebildet ist. Für Zargenanschlußausbildungen bei Anordnungen,bei welchen die Dachisolierung durch eine weitere Folie 17 abgedeckt ist, wird, wie in der Figur dargestellt, an das Anschlußstück 16 ein Winkel 18 angebracht, der ebenfalls kunststoffbeschichtet sein kann. Die Isolierfolie 17 wird bei dieser Lösung bis an den Winkel 18 herangeführt und auf den nach außen weisenden Schenkel folienverschweißt, sodann an dem senk­rechten Schenkel des Winkels 18 durch Folienverschweißung be­festigt und senkrecht an der Wand der Zarge 2 weitergeführt und schließlich an dem Schenkel 11a des Winkelbleches 11 wie be­schrieben folienverschweißt. Diese Ausgestaltung hat den Vorteil, daß die Folie 17 bis an die Zarge 2 herangeführt werden kann, d.h. es ist nicht nötig wie bei den bekannten Ausführungen einen Keil zur Befestigung und Führung der Folie 17 vorzusehen. Außer­dem wird die Folie 17 durch das Verschweißen auf dem waagrechten Schenkel 14c des Anschlußstückes 14 bereits gehalten, so daß der an der Zarge 2 hochgezogene Teil der Folie 17 nicht durch Lage­änderungen der Folie 17 auf der Dachisolierung 16 beansprucht wird. Diese Lösung trägt wesentlich zur sicheren, staub- und wasserdichten Befestigung der Folie 17 an der Zarge 2 bei.At the lower end of the frame 2 there is also a connector 14 on the side facing away from the light opening, with a vertical leg 14a, a leg 14b foamed into the PU foam and a leg 14c that repels from the frame 2 arranged, of which the legs 14a and 14c are also plastic-coated, for connecting a roof insulation film 15, which is film-welded in the manner described. The attachment to the roof 12 can also be carried out by the leg 14c together with the leg 13 of the thin sheet metal frame 5. The roof insulation 16 lies on this connecting part 14, which is brought up to the frame 2. On the same side of the frame 2, a further connecting piece 16, which is U-shaped, is foamed and also plastic-coated for connecting the raised roof insulation film 15, if the roof insulation 16 is of outstanding construction. For frame connection designs in arrangements in which the roof insulation is covered by a further film 17, as shown in the figure, an angle 18 is attached to the connector 16, which can also be plastic-coated. The insulating film 17 is brought up to the angle 18 in this solution and film-welded to the outward-pointing leg, then attached to the vertical leg of the angle 18 by film welding and continued vertically on the wall of the frame 2 and finally on the leg 11a of the angle plate 11 foil-sealed as described. This configuration has the advantage that the film 17 can be brought up to the frame 2, ie it is not necessary to provide a wedge for fastening and guiding the film 17 as in the known designs. In addition, the film 17 is already held by welding on the horizontal leg 14c of the connecting piece 14, so that the part of the film 17 drawn up on the frame 2 is not stressed by changes in the position of the film 17 on the roof insulation 16. This solution contributes significantly to the secure, dustproof and watertight fastening of the film 17 to the frame 2.

Die aufgezeigte Zarge zeichnet sich durch eine einfache Her­stellung und insbesondere durch geringes Gewicht und damit geringe Dachbelastung aus. Durch die Dünnblechaussteifung durch den eingeschäumten Kunststoff ergibt sich eine ausreichend steife Anordnung mit glatter Außenfläche,an die eine Dachbahn oder Dachfolie in einfacher Weise direkt oder über ein in die Ausschäumung eingebrachter metallischer Streifen angeschlossen werden kann.The frame shown is characterized by simple manufacture and in particular by low weight and thus low roof load. The thin sheet stiffening through the foamed-in plastic results in a sufficiently rigid arrangement with a smooth outer surface, to which a roofing membrane or roofing film can be connected in a simple manner directly or via a metallic strip introduced into the foaming.
