Description

Die Erfindung betrifft eine Überdachungs-Anordnung zum Überdachen einer vorgebbaren Fläche, insbesondere für Vorplätze, Wintergärten, _Pergolen oder Hauseingänge, mit einer gitterartigen Tragkonstruktion.The invention relates to a roofing arrangement for roofing over a predeterminable area, in particular for forecourts, winter gardens, pergolas or house entrances, with a grid-like supporting structure.

Es sind vielfältige Versuche unternommen worden, eine bestimmte Fläche wie einen Vorplatz, einen Wintergarten, eine Pergola oder einen Hauseingang zu überdachen. Alle diese Versuche haben jedoch nicht zu voll zufriedenstellenden Ergebnissen geführt. Bekannte Überdachungen sind entweder in ihren Abmessungen nicht hinreichend flexibel und/oder bedürfen an der Baustelle eines erheblichen Arbeitsaufwandes.Various attempts have been made to cover a certain area such as a forecourt, a winter garden, a pergola or a house entrance. However, all of these attempts have not led to fully satisfactory results. Known canopies are either not sufficiently flexible in their dimensions and / or require a considerable amount of work at the construction site.

Der Erfindung liegt die Aufgabe zugrunde, eine Überdachungs-Anordnung der eingangs näher genannten Art zu schaffen, welche in ihren Abmessungen an die Gegebenheiten der jeweiligen Anwendungsfälle besonders flexibel anzupassen ist und dabei zugleich auf außerordentlich wirtschaftliche Weise erstellt werden kann.The invention has the object of providing a Canopy - to create arrangement of the type specifically mentioned above, which is particularly flexible to adapt in size to the conditions of the respective applications and can be while at the same time created in an extremely economical manner.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß industriell vorgefertigte, auf ein vorgegebenes Gitterfeld-Rastermaß abgestimmte Träger vorgesehen sind, die auf vertikalen Stützen oder Wandkonsolen aufliegen, daß die Träger als Verbundträger ausgebildet sind, welche zwei zueinander symmetrisch angeordnete Stahlblech-Profile aufweisen, zwischen denen zumindet im Bereich von Kreuzungen, L- und T-förmigen' Anschlüssen Leichtmetall-Verbindungsbleche angeordnet sind, daß die Stahlblech-Profile und die Leichtmetall-Verbindungsbleche miteinander durch Verbindungsschrauben verschraubt sind und daß die Stahlblech-Profile mit abgewinkelten Randbereichen im oberen Teil eines Trägers eine im wesentlichen V-förmige Rinne bilden, in welche jeweils die Ränder von kuppelförmigen Dachhaut-Elementen hineinragen, die jeweils ein Gitterfeld abdecken.To achieve this object, the invention provides that industrially prefabricated supports are provided which are matched to a predetermined grid field grid dimension and which rest on vertical supports or wall brackets, that the supports are designed as composite supports which have two steel sheet profiles arranged symmetrically to one another, between which at least in the area of intersections, L- and T - shaped connections are arranged light metal connecting plates, that the steel plate profiles and the light metal connecting plates are screwed together by connecting screws and that the steel plate profiles with angled edge areas in the upper part of a Carrier form an essentially V-shaped channel, into each of which the edges of dome-shaped roof skin elements protrude, each of which covers a grid field.

Gemäß der Erfindung ist der wesentliche Vorteil erreichbar, daß einerseits ein Rastermaß mit verhältnismäßig kleinen Gitterfeldern vorgesehen werden kann, so daß dadurch induviduellen Wünschen hinsichtlich der Abmessungen ohne weiteres Rechnung getragen werden kann, während andererseits praktisch vollständig vorgefertigte Bauteile verwendet werden können, so daß der Arbeitsaufwand an der Baustelle besonders gering ist. Dadurch ergibt sich nicht nur der weitere Vorteil, daß eine gemäß der Erfindung ausgebildete Überdachung in sehr kurzer Zeit an der Baustelle fertiggestellt werden kann, dies kann auch auf erstaunlich wirtschaftliche Weise geschehen.According to the invention, the main advantage is achievable that on the one hand a grid dimension with relatively small grid fields can be provided, so that individual requests regarding the dimensions can be taken into account without any problems, while on the other hand practically completely prefabricated components can be used so that the workload is particularly low at the construction site. This not only results in the further advantage that a canopy designed according to the invention can be completed on the construction site in a very short time, this can also be done in an amazingly economical manner.

Eine besonders bevorzugte Ausführungsform der erfindungsgemäßen Anordnung sieht vor, daß Basisträger vorgesehen sind, welche eine Länge haben, die der Kantenlänge eines Gitterfeldes entspricht, wobei in jedem Gittereckpunkt wenigstens ein Basisträger und ein dazu unter einem rechten Winkel verlaufender Querträger zusammentreffen.A particularly preferred embodiment of the arrangement according to the invention provides that base girders are provided which have a length which corresponds to the edge length of a lattice field, wherein at least one base girder and a crossbeam running at right angles meet in each lattice corner point.

Weiterhin kann vorzugsweise vorgesehen sein, daß Doppelbasisträger vorgesehen sind, welche zwei Gitterfelder übergreifen und welche in ihrem mittleren Bereich, in welchem für eine Kreuzung oder für einen T-förmigen Anschluß eines quer zum Basisträger verlaufenden Querträgers am oberen Rand eine Ausklinkung vorgesehen ist.Furthermore, it can preferably be provided that double base beams are provided which overlap two grid fields and which in their central region, in which a notch is provided at the upper edge for an intersection or for a T-shaped connection of a cross beam extending transversely to the base beam.

Durch die Verwendung von Basisträgern und Doppelbasisträgern wird die Anpassung an individuell gewünschte Abmessungen weiter gefördert. Es hat sich gezeigt, daß mit einem Rastermaß von 300 Millimeter eine horizontale, freitragende, gitterartige Tragkonstruktion erstellt werden kann, und zwar aus vollständig vorgefertigten Bauteilen, die an praktisch alle Abmessungswünsche angepaßt werden kann.The use of base supports and double base supports further adapts to individually desired dimensions. It has been shown that a horizontal, self-supporting, lattice-like support structure can be created with a grid dimension of 300 millimeters, and that from completely prefabricated components that can be adapted to practically all dimensional requirements.

Eine besonders vorteilhafte Möglichkeit zur Herstellung der Ausklinkung ergibt sich dadurch, daß das Stahlblech-Profil zur Herstellung der Ausklinkung eine als Sollbruchlinie dienende Keilnut oder ein Langloch aufweist.A particularly advantageous possibility for producing the notch results from the fact that the steel sheet profile for producing the notch has a keyway serving as a predetermined breaking line or an elongated hole.

Dabei hat sich eine Anordnung gut bewährt, welche vorsieht, daß die Keilnut sich im unteren Teil des zur Bildung der V-förmigen Rinne abgewinkelten Randbereiches befindet.Here, an arrangement has proven itself that provides that the keyway is located in the lower part of the angled area to form the V-shaped channel.

Die V-förmige Rinne erweist sich zum Abführen von Regenwasser als sehr gut geeignet und wird gemäß einer vorteilhaften Weiterbildung des Erfindungsgegenstandes dadurch geschaffen, daß der zur Bildung der V-förmigen Rinne abgewinkelte Randbereich um einen Winkel von etwa 45 Grad gegenüber einer vertikal anzuordnenden Trägerhauptfläche abgewinkelt ist.The V - shaped gutter proves to be very well suited for removing rainwater and, according to an advantageous further development of the subject of the invention, is created in that the edge region which is angled to form the V-shaped gutter is angled by an angle of approximately 45 degrees with respect to a vertical main carrier surface is.

Sowohl die Biegesteifigkeit als auch die Knickfestigkeit der Träger wird dadurch besonders günstig beeinflußt, daß das Stahlblech-Profil des Trägers in seinem unteren Bereich einen nach einer Seite abgewinkelten Bereich aufweist, welcher in derselben Richtung wie der obere Randbereich abgewinkelt ist, und daß der untere Rand des abgewinkelten Bereiches in entgegengesetzter Richtung zu der genannten Abwinklung derart umgebogen ist,.daß eine Ausbauchung und ein im wesentlichen rechtwinklig zu der Trägerhauptfläche angeordneter Untergurt gebildet ist, dessen Rand in der durch die Trägerhauptfläche festgelegten Ebene angeordnet ist.Both the bending stiffness and the buckling strength of the beams are influenced particularly favorably in that the steel sheet profile of the beam in its lower region has an angled region to one side, which is angled in the same direction as the upper edge region, and that the lower edge of the angled area is bent in the opposite direction to the above-mentioned bend in such a way that a bulge and a lower flange arranged essentially at right angles to the main carrier surface is formed, the edge of which is arranged in the plane defined by the main carrier surface.

Dabei kann vorzugsweise vorgesehen sein, daß die Stahlblech-Profile kaltverformte Profilteile sind.It can preferably be provided that the steel sheet profiles are cold-formed profile parts.

Die zwischen den Stahlblech-Profilen angeordneten Leichtmetall-Verbindungsbleche können natürlich auch als Strangpreßprofile oder auch als Gußteile ausgebildet sein, ohne den Rahmen der Erfindung zu verlassen. Es dienen auch die in der vorliegenden Beschreibung niedergelegten Materialangaben vor allem zur Veranschaulichung des Erfindungsgegenstandes, und es können im Rahmen der Erfindung auch andere Materialien mit hinreichender Festigkeit verwendet werden.The light metal connecting plates arranged between the steel sheet profiles can of course also be designed as extruded profiles or as cast parts without leaving the scope of the invention. It is also used in the present Description of deposited material information mainly to illustrate the subject matter of the invention, and other materials with sufficient strength can be used within the scope of the invention.

In der Praxis hat sich eine Anordnung gut bewährt, welche sich dadurch auszeichnet, daß das Stahlblech-Profil eine Höhe von insgesamt etwa 180 mm aufweist, von welcher der obere abgewinkelte Randbereich etwa 30 mm, die Trägerhauptfläche etwa 100 mm und der untere abgewinkelte Bereich etwa 50 mm einnehmen.In practice, an arrangement has proven itself which is characterized in that the steel sheet profile has a total height of approximately 180 mm, of which the upper angled edge region is approximately 30 mm, the main carrier surface is approximately 100 mm and the lower angled region is approximately Take 50 mm.

Dabei kann vorgesehen sein, daß das Stahlblech-Profil eine Blechstärke von etwa 2,5 mm aufweist.It can be provided that the steel sheet profile has a sheet thickness of about 2.5 mm.

Eine sehr vorteilhafte Weiterbildung des Erfindungsgegenstandes zeichnet sich weiterhin dadurch aus, daß das Stahlblech-Profil in der im eingebauten Zustand vertikal angeordneten Trägerhauptfläche in deren oberer Hälfte jeweils im Rasterabstand angeordnete, horizontal verlaufende Langlöcher aufweist.A very advantageous further development of the subject matter of the invention is further characterized in that the steel sheet profile in the main carrier surface arranged vertically in the installed state has horizontally extending elongated holes in the upper half of each of which are arranged at grid intervals.

Die Langlöcher erfüllen eine vorteilhafte Doppelfunktion, weil sie einerseits dazu dienen, daß Halteklammern für Dachhaut-Elemente in diese Langlöcher eingreifen, während die weitere Funktion dieser Langlöcher darin zu sehen ist, daß sie die Ausklinkung der Doppelbasisträger stark vereinfachen. Es braucht nämlich zur Herstellung einer Ausklinkung lediglich an den beiden Enden eines Langloches von oben quer ein Einschnitt vom Rand des Trägers bis zum Langloch ausgeführt zu werden, um die gewünschte Ausklinkung zu erzeugen.The elongated holes fulfill an advantageous double function because, on the one hand, they serve for holding clips for roof skin elements to engage in these elongated holes, while the further function of these elongated holes is that they greatly simplify the release of the double base beams. To produce a notch, it is only necessary to make an incision transversely from above at the two ends of an elongated hole from the edge of the carrier to the elongated hole in order to produce the desired notch.

Weiterhin kann gemäß einer besonders vorteilhaften Ausgestaltung des Erfindungsgegenstandes vorgesehen sein, daß das Stahlblech-Profil auf der Trägerhauptfläche sowie an dem Untergurt in einem Abstand voreinander, welcher einem vorgebbaren Bruchteil des Rastermaßes entspricht, Reihen von Ankörnungen aufweisen. Dabei sieht eine vorteilhafte Ausgestaltung weiterhin vor, daß auf der Trägerhauptfläche zwei Reihen von Ankörnungen vorgesehen sind, welche die Bohrungen für die Verbindungsschrauben sowie die Schnittlängen für die Träger markieren.Furthermore, according to a particularly advantageous embodiment of the subject matter of the invention, it can be provided that the steel sheet profile on the main carrier surface and on the lower flange at a distance from one another, which corresponds to a predeterminable fraction of the grid dimension, have rows of punchings. An advantageous embodiment further provides that two rows of punchings are provided on the main carrier surface, which mark the bores for the connecting screws and the cutting lengths for the carriers.

Die Ankörnungen dienen einerseits als Maßeinheit zum Ablängen der Träger und andererseits zum Erstellen des Bohrbildes ohne Bohrschablone für die Trägeranschlüsse.The markings serve on the one hand as a unit of measurement for cutting the beams to length and on the other hand for creating the drilling pattern without a drilling template for the beam connections.

In ähnlicher Weise wie die Langlöcher werden auch die in der Längsrichtung der Träger in einer alternativen Ausführungsform vorgesehenen Keilnuten zur Ausbildung der Ausklinkungen verwendet. Es kann nämlich ein Teilbereich des Trägers einfach ausgebrochen werden, nachdem in der Querrichtung zu der Keilnut vom Rand des Trägers her bis zur Keilnut eingesägt wurde.In a manner similar to the elongated holes, the keyways provided in the longitudinal direction of the carriers in an alternative embodiment are used to form the notches. This is because a portion of the carrier can simply be broken out after sawing in the direction transverse to the keyway from the edge of the carrier to the keyway.

Zur Versteifung der Träger kann weiterhin vorzugsweise vorgesehen sein, daß die Verbindungsbleche im Querschnitt die Form eines umgekehrten "T" aufweisen,dessen Querschenkel innerhalb der Ausbauchung angeordnet und mit dem horizontalen Untergurt verschraubt ist.For stiffening the beams, it can also be preferably provided that the connecting plates have the shape of an inverted "T" in cross-section, the transverse legs of which are arranged within the bulge and are screwed to the horizontal lower flange.

Um Basisträger oder Doppelbasisträger jeweils mit ihren Enden aneinander zu fügen sieht eine besonders vorteilhafte Ausführungsform des Erfindungsgegenstandes vor, daß zwischen den Enden von Basisträgern bzw. Doppelbasisträgern jeweils ein Kreuzknotenelement angeordnet ist, welches aus einem einstückig ausgebildeten, balkenkreuzartig geformten, mit gabelartig angeordneten Doppelflanschen ausgestatteten Leichtmetallkörper besteht, zwi- . schen dessen Doppelflanschen die Leichtmetall-Verbindungsbleche angeordnet sind.In order to join base supports or double base supports with their ends to each other, a particularly advantageous embodiment of the subject matter of the invention provides that between the ends of base supports or double base supports a cross-knot element is arranged, which consists of a one-piece, cross-beam-shaped light metal body equipped with fork-like double flanges exists, between whose double flanges the light metal connecting plates are arranged.

Dabei kann die Anordnung vorteilhafterweise derart getroffen sein, daß jeder Doppelflansch zwei übereinander angeordnete Bohrungen aufweist, die mit entsprechenden Öffnungen in den Leichtmetall-The arrangement can advantageously be such that each double flange has two bores arranged one above the other, which have corresponding openings in the light metal

Verbindungsblechen fluchten und von denen die untere Öffnung als Bohrung mit dem gleichen Durchmesser wie die untere Bohrung im Doppelflansch ausgebildet ist und die obere Öffnung ein sich in horizontaler Richtung erstreckendes Langloch ist, und daß zwischen stirnseitigen Rändern der Leichtmetall-Verbindungsbleche ein in dem Kreuzknotenelement drehbarer Exzenternocken angeordnet ist, an dessen Umfangsfläche die stirnseitigen Ränder der Leichtmetall-Verbindungsbleche abstützbar sind.Connecting plates are aligned and of which the lower opening is designed as a hole with the same diameter as the lower hole in the double flange and the upper opening is an elongated hole extending in the horizontal direction, and that between the front edges of the light metal connecting plates an eccentric cam rotatable in the cross-knot element is arranged, on the circumferential surface of the front edges of the light metal connecting plates can be supported.

Eine solche Anordnung kann vorzugsweise dadurch weitergebildet werden, daß der Exzenternocken im Querschnitt polygonal ausgebildet ist, wobei jeweils auf gleichem Abstand vom Drehpunkt zwei zueinander parallele Flächen vorgesehen sind.Such an arrangement can preferably be further developed in that the eccentric cam is polygonal in cross section, two mutually parallel surfaces being provided at the same distance from the fulcrum.

Bei einer derartigen Anordnung kann an den Kreuzknoten jeweils eine Überhöhung durchgeführt werden, indem nämlich der betreffende Kreuzknotenbereich durch eine Montagestütze leicht angehoben wird, wobei die unteren Verbindungszapfen als Gelenk wirken und die oberen Verbindungszapfen in einem Langloch jeweils eine horizontale Bewegung ausführen können, wonach die Stirnseiten der Trägeranschlüsse durch den Exzenternocken auseinandergedrückt gehalten werden.With such an arrangement, an elevation can be carried out on each of the cross nodes, namely by lifting the relevant cross node area slightly by means of an assembly support, the lower connecting pins acting as a joint and the upper connecting pins each being able to carry out a horizontal movement in an elongated hole, after which the end faces the carrier connections are held apart by the eccentric cam.

Um eine gute Abdichtung der erfindungsgemäßen Überdachung gegen Regenwasser zu gewährleisten, kann vorzugsweise vorgesehen sein, daß zwischen in die V-förmige Rinne hineinragenden Rändern von Dachhaut-Elementen ein dauerelastisches Dichtungsband angeordnet ist.In order to ensure a good seal of the roofing according to the invention against rainwater, it can preferably be provided that a permanently elastic sealing tape is arranged between the edges of roof skin elements projecting into the V-shaped channel.

Die Montage wird dadurch wesentlich erleichtert, daß entlang den Rändern der Dachhaut-Elemente, die in die V-förmige Rinne hineinragen, ein doppelseitig klebendes Band angeordnet und mit zur Montage lösbaren Schutzband abgedeckt ist.The assembly is considerably facilitated in that a double-sided adhesive tape is arranged along the edges of the roof skin elements, which protrude into the V-shaped channel, and is covered with protective tape that can be removed for assembly.

Vorzugsweise ist weiterhin vorgesehen, daß die in die V-förmige Rinne hineinragenden Ränder der kuppelförmigen Dachhaut-Elemente durch elastische Halteklammern gehalten sind, die an den Trägern angreifen.It is also preferably provided that the edges of the dome-shaped roof skin elements protruding into the V-shaped groove are held by elastic retaining clips which are attached to the carriers attack.

Diese Halteklammern zeichnen sich nach einer vorteilhaften Ausführungsform des Erfindungsgegenstandes dadurch aus, daß die Halteklammern jeweils in ihrem oberen Bereich V-förmig geformte, die Ränder der Dachhaut-Elemente übergreifende Ausleger aufweisen und in ihrem unteren Bereich in Öffnungen in den Trägern eingreifende Haken aufweisen.According to an advantageous embodiment of the subject matter of the invention, these retaining clips are characterized in that the retaining clips each have V-shaped cantilevers in their upper region which extend over the edges of the roof skin elements and have hooks engaging in openings in the carriers in their lower region.

Vorteilhafterweise ist die Anordnung dabei derart getroffen, daß die Haken in Langlöcher eingreifen, die in horizontaler Richtung in den Trägerhauptflächen angeordnet sind.The arrangement is advantageously made such that the hooks engage in elongated holes which are arranged in the horizontal direction in the main carrier surfaces.

Um die erfindungsgemäße Überdachung auch optisch besonders vorteilhaft auszugestalten, kann weiterhin vorzugsweise vorgesehen sein, daß eine an einem Träger anbringbare Halterung vorgesehen ist, welche zur Anbringung einer vertikalen Randverblendung eine obere und eine untere Schiene aufweist, in welche nachträglich eine praktisch beliebig gestaltete Zierverblendung einzusetzen ist.In order to also design the roof according to the invention in a particularly advantageous manner, provision can furthermore preferably be made for a mount which can be attached to a carrier and which has an upper and a lower rail for attaching a vertical edge covering, into which a practically arbitrarily designed decorative covering can subsequently be inserted .

Diese Anordnung zeichnet sich vorzugsweise dadurch aus, daß die untere Schiene eine nach oben offene U-förmige Rinne aufweist.This arrangement is preferably characterized in that the lower rail has an upwardly open U-shaped channel.

Um nicht nur in den äußeren Randbereichen eine besonders ansprechende Verblendung anbringen zu können, sondern um auch unter der Dachkonstruktion eine Zierblende vorteilhaft anbringen zu können, sieht eine weitere Ausgestaltung des Erfindungsgegenstandes vor, daß die untere Schiene eine zur Aufnahme einer horizontalen Verblendung dienende weitere U-Schiene aufweist, bei welcher das "U" horizontal angeordnet ist.In order not only to be able to attach a particularly appealing panel in the outer edge regions, but also to be able to advantageously attach a decorative panel under the roof structure, a further embodiment of the subject matter of the invention provides that the lower rail has a further U-shaped portion for receiving a horizontal panel. Has rail, in which the "U" is arranged horizontally.

Insgesamt läßt sich gemäß der Erfindung in sehr weitgehender Anpassung an praktisch beliebige Wünsche hinsichtlich Abmessungen und optischer Ausgestaltung eine Überdachung aufbauen, welche einerseits in wirtschaftlicher Hinsicht die Vorteile einer industriellen Serienfertigung ausnutzt und dabei jedoch zugleich hinsichtlich der optisch-ästhetischen Gestaltung freizüge Gestaltungsmöglichkeiten bietet.Overall, according to the invention, a canopy can be built to a very large extent to practically any desired dimensions and optical design, which on the one hand takes advantage of the advantages of industrial series production in economic terms and at the same time offers free design options with regard to the optical-aesthetic design.

The covering is carried out by roof skin elements, each of which covers a grid area 13. Depending on the intended use, either transparent or opaque roof skin elements can be used. Preferably transparent or translucent dome segments can be used if it is desired that the space under the roof according to the invention be as bright as possible.

Bei der in der Fig. 1 veranschaulichten Anordnung ist beispielsweise zwischen zwei Basisträgern, die im unteren Bereich der Fig. 1 dargestellt sind, ein T-förmiger Anschluß mit einem Doppelbasisträger 11 dargestellt, bei welchem ein nach Art eines Kreuzknotenelementes 32 ausgebildetes T-Stück verwendet wird. Ein solches Kreuzknotenelement mit einem in der Fig. 1 rein schematisch eingezeichneten Exzenternocken wird unten anhand der Fig. 4 und 5 näher erläutert.In the arrangement illustrated in FIG. 1, a T-shaped connection with a double base support 11 is shown, for example, between two base supports, which are shown in the lower region of FIG. 1, in which a T-piece designed in the manner of a cross-knot element 32 is used becomes.

The supporting structure is supported either on wall brackets 43 or on supports 42.

Die Fig. 2 veranschaulicht in einem schematischen Aufriß einen Doppelbasisträger 11, der eine Ausklinkung 14 aufweist. Der Doppelbasisträqer 11 ist in einer Verbundbauweise hergestellt. Er besteht aus zwei Stahlblech -Profilen 15 und 16, die über ein dazwischen angeordnetes Leichtmetall-Verbindungsblech 19 miteinander verbunden und versteift sind. Das Leichtmetall-Verbindungsblech 19 ist im Bereich von T-förmigen Anschlüssen sowie in Kreuzungsbereichen vorgesehen, kann sich jedoch über einen vorgebbaren Bereich entlang dem Träger erstrecken und in Sonderfällen auch durchgehend vorhanden sein. Es wird durch das Leichtmetall-Verbindungsblech 19 die durch die Ausklinkung verursachte Profilschwächung kompensiert. Es kann ein Verbindungsblech in Form eines Flachmaterials verwendet werden, welches natürlich auch auf beliebige Weise hergestellt sein kann. Gemäß der Darstellung in der Fig. 3 kann als Verbindungsblech auch ein umgekehrtes T-Profil verwendet werden. Die Fig. 3 veranschaulicht den Aufbau eines gemäß der Erfindung verwendeten Verbundträgers. Gemäß der Darstellung in der Zeichnung weisen die Stahlblech-Profile 15 und 16 grundsätzlich dieselbe Form auf, so daß in der Fertigung nur ein einziges Profil hergestellt werden muß. Jedes Stahlblech-Profil 15 und 16 weist an seinem oberen Rand einen abgewinkelten Bereich auf, der bei der in der Fig. 3 veranschaulichten Ausführungsform gegenüber der Trägerhauptfläche um etwa 45 Grad abgewinkelt ist. Dadurch wird zwischen den beiden oberen abgewinkelten Bereichen der Stahlblech-Profile 15 und 16 eine V-förmige Rinne gebildet. Die weitere Ausgestaltung und die Funktion dieser V-förmigen Rinne werden unten anhand der Fig. 6 näher erläutert.FIG. 2 illustrates in a schematic elevation a double base support 11 which has a notch 14. The double base 11 is made in a composite construction. It consists of two sheet steel profiles 15 and 16, which are connected and stiffened via a light metal connecting plate 19 arranged between them. The light metal connecting plate 19 is provided in the area of T-shaped connections and in intersection areas, but can extend over a predeterminable area along the support and can also be present continuously in special cases. The weakening of the profile caused by the notching is compensated by the light metal connecting plate 19. A connecting plate in the form of a flat material can be used, which of course can also be produced in any way. 3, an inverted T-profile can also be used as the connecting plate. 3 illustrates the structure of a composite beam used in accordance with the invention. As shown in the drawing, the steel sheet profiles 15 and 16 basically have the same shape, so that only a single profile has to be produced in production. Each steel sheet profile 15 and 16 has an angled area at its upper edge, which in the embodiment illustrated in FIG. 3 is angled by approximately 45 degrees with respect to the main carrier surface. As a result, a V-shaped channel is formed between the two upper angled regions of the steel sheet profiles 15 and 16. The further configuration and the function of this V-shaped channel are explained in more detail below with reference to FIG. 6.

Im unteren Bereich weisen die Stahlblech-Profile 15 und 16 jeweils einen in derselben Richtung wie im oberen Bereich ausgestellten Bereich auf, dessen unterer Rand in entgegengesetzter Richtung zu der gebildeten Ausbauchung derart umgebogen ist, daß ein im wesentlichen horizontaler Untergurt gebildet wird. Auf diese Weise entsteht im unteren Bereich des Verbundträgers eine Versteifungsausbauchung. Zwischen den beiden Stahlblech-Profilen 15 und 16 ist gemäß der Darstellung in der Fig. 3 ein T-förmig ausgebildetes Leichtmetall-Verbindungsblech 19 angeordnet, welches mit Hilfe von Verbindungsschrauben 20 und 21 mit den Stahlblech-Profilen 15 und 16 verbunden ist. Das T-förmige Profil des Leichtmetall-Verbindungsbleches 19 weist in seinem T-Längsschenkel Bohrungen 30 auf, -die in der Fig. 2 näher dargestellt sind. Durch die Bohrungen 30 sind die Verbindungsschrauben 20 hindurchgeführt, welche den Verbundträger unterhalb der V-förmigen.Rinne 18 zusammenhalten. Durch den Untergurt 23 sind die Verbindungsschrauben 21 hindurchgeführt, welche die Stahlblech-Profile 15 und 16 mit dem T-Querschenkel des Leichtmetall-Verbindungsbleches 19 verbinden, wie es aus den Fig. 2 und 3 deutlich erkennbar ist.In the lower area, the steel sheet profiles 15 and 16 each have an area exhibited in the same direction as in the upper area, the lower edge of which is bent in the opposite direction to the bulge formed in such a way that an essentially horizontal lower flange is formed. This creates a stiffening bulge in the lower area of the composite beam. A T-shaped light metal connecting plate 19 is arranged between the two steel sheet profiles 15 and 16, as shown in FIG. 3, which is connected to the steel sheet profiles 15 and 16 by means of connecting screws 20 and 21. The T-shaped profile of the light metal connecting plate 19 has holes 30 in its T longitudinal leg, which are shown in more detail in FIG. 2. The connecting screws 20, which hold the composite carrier below the V-shaped channel 18, are passed through the bores 30. The connecting screws 21, which connect the steel sheet profiles 15 and 16 to the T-cross leg of the light metal connecting sheet 19, are passed through the lower flange 23, as can be clearly seen from FIGS. 2 and 3.

Nachfolgend wird anhand der Fig. 4 und 5 ein Kreuzknotenbereich näher beschrieben. Ein Kreuzknotenelement 32, welches in einem Horizontalschnitt grundsätzlich die Form eines Balkenkreuzes aufweist und Doppelflanschen 33 hat, ist mit den Leichtmetall-Verbindungsblechen 19 mit Hilfe von Bolzen verbunden. Gemäß der Darstellung in den Fig. 4 und 5 ragen von zwei einander gegenüber angeordneten Seiten Leichtmetall-Verbindungsbleche 19 in die Zwischenräume zwischen den Doppelflanschen 33 des Kreuzknotenelementes 32. Im oberen Bereich des Kreuzknotenelementes 32 ist zwischen den auf Abstand voneinander angeordneten Stirnseiten der Leichtmetall-Verbindungsbleche 19 ein Exzenternocken 36 angeordnet. Im unteren Bereich haben sowohl die Leichtmetall-Verbindungsbleche 19 als auch die Doppelflanschen 33 des Kreuzknotenelementes 32 miteinander fluchtende und als Bohrungen ausgebildete Öffnungen 35 . Im oberen Bereich sind in einer grundsätzlich fluchtenden Anordnung in den Leichtmetall-Verbindungsblechen 19 Langlöcher 34 vorgesehen, während in den Doppelflanschen 33 des Kreuzknotenelementes 32 Bohrungen 35 angeordnet sind. Durch die Bohrungen 35 sowie die entsprechenden Langlöcher 34 sind Zapfen hindurchgeführt. Wenn nun im Bereich eines Kreuzknotens eine Überhöhung durchgeführt werden soll, so daß aus diesem Bereich das Regenwasser leicht ablaufen kann, kann dies bei der erfindungsgemäßen Anordnung auf folgende Weise geschehen. Zunächst wird unter das Kreuzknotenelement 32 eine Stütze gesetzt. Wenn diese Stütze den Kreuzknotenbereich leicht nach oben drückt, können die stirnseitigen Ränder der Leichtmetall-Verbindungsbleche 19 im Bereich des Exzenternockens 36 auseinander geführt werden, indem nämlich die Bolzen in den Langlöchern 34 geführt werden, wobei die durch die Bohrungen 35 im unteren Bereich hindurchgeführten Bolzen als Drehlagerzapfen wirken. Mit anderen Worten, es werden beim Hochdrücken der Stützen die Trägeranschlüsse im oberen Bereich der Verbindungsbleche auseinander gedrückt, wobei die unteren Verbindungszapfen als Drehgelenk wirken und die oberen Verbindungszapfen in den Langlöchern geführt sind. Durch entsprechende Einstellung des Exzenternockens 36 können die stirnseitigen Ränder der Verbindungsbleche 19 bei entsprechender Dimensionierung der Nockenflächen gegeneinder abgestützt oder verkeilt werden. Die Stütze kann dann unter dem _Kreuzknotenbereich wieder entfernt werden. Wenn an dem Exzenternocken 36 Nockenflächen mit unterschiedlichen Abständen von der Drehachse vorgesehen werden, können auf diese Weise unterschiedliche Überhöhungen herbeigeführt und durch entsprechende Einstellung des Exzenternockens 36 fixiert werden.A cross node region is described in more detail below with reference to FIGS. 4 and 5. A cross knot element 32, which in a horizontal section basically has the shape of a beam cross and has double flanges 33, is connected to the light metal connecting plates 19 by means of bolts. As shown in FIGS. 4 and 5, light metal connecting plates 19 protrude from two mutually opposite sides into the spaces between the double flanges 33 of the cross node element 32. In the upper region of the cross node element 32 there is between the front sides of the light metal connecting plates which are arranged at a distance from one another 19 an eccentric cam 36 is arranged. In the lower area, both the light metal connecting plates 19 and the double flanges 33 of the cross-knot element 32 are cursed to one another ends and designed as holes 35th In the upper area, in a generally aligned arrangement, 19 elongated holes 34 are provided in the light metal connecting plates 19, while 32 holes 35 are arranged in the double flanges 33 of the cross-knot element. Pins are passed through the bores 35 and the corresponding elongated holes 34. If an elevation is now to be carried out in the area of a cross knot so that the rainwater can run off easily from this area, this can be done in the arrangement according to the invention in the following manner. First, a support is placed under the cross-knot element 32. If this support pushes the cross-knot area slightly upwards, the front edges of the light metal connecting plates 19 can be moved apart in the area of the eccentric cam 36, namely by the bolts being guided in the elongated holes 34, the bolts passing through the holes 35 in the lower region act as a pivot pin. In other words, when the supports are pushed up, the carrier connections in the upper region of the connecting plates are pressed apart, the lower connecting pins acting as a swivel joint and the upper connecting pins being guided in the elongated holes. By appropriate adjustment of the eccentric cam 36, the front edges of the connecting plates 19 can be supported or wedged against one another if the cam surfaces are dimensioned accordingly. The column can then be removed under the cross-knot area. If 36 cam surfaces are provided on the eccentric cam with different distances from the axis of rotation, different elevations can be brought about in this way and fixed by appropriate adjustment of the eccentric cam 36.

Die Fig. 6 veranschaulicht in einem schematischen Vertikalschnitt die Ausgestaltung der V-förmigen Rinne 18. Innerhalb der abgewinkelten oberen Bereiche der Stahlblech-Profile 15 bzw. 16 ragen die Ränder von Dachhaut-Elementen 22 in die V-förmige Rinne 18 hinein. Die Ränder der Dachhaut-Elemente 22 sind mit einem doppelseitig klebenden Band 38 versehen, welches bereits bei der Fertigung angebracht wird. Bei der Montage wird die äußere Schutzschicht eines solchen doppelseitig klebenden Bandes 38 entfernt, so daß zwischen den Rändern der Dachhaut-Elemente 22 ein Dichtungsband 37 eingelegt werden kann, welches mit den Bändern 38 durch eine Klebeverbindung fest und dicht verbunden wird. In der Fig. 6 ist auch eine Halteklammer 25 veranschaulicht, welche in ihrem oberen Bereich Y-förmig auseinander gespreizte Ausleger 26 aufweist, die sich auf die doppelseitig Klebenden Bänder 38 auflegen. In ihrem unteren Bereich weist die Halteklammer 25 nach außen abgewinkelte Haken 27 auf, die in die Langlöcher 34 eingreifen, welche in den Stahlblech-Profilen 15 und 16 ausgebildet sind. Die Langlöcher 34 sind insbesondere aus der Darstellung der Fig. 7 ersichtlich. Die Halteklammern 25 können in vorgebbaren Abständen voneinander eingesetzt werden. An denjenigen Stellen, an denen keine Halteklammern 25 vorhanden sind, kommt eine durchgehende Klebeverbindung zwischen dem Dichtungsband 37 und den doppelseitig klebenden Bändern 38 zustande. Im Bereich der V-förmigen Rinne wird durch die oben beschriebene Ausführungsform des Erfindungsgegenstandes einerseits eine gut abgedichtete Regenrinne gebildet, und es werden zugleich mit Hilfe der Halteklammern 25 die Ränder der Dachhaut-Elemente fest verankert.6 illustrates in a schematic vertical section the configuration of the V-shaped channel 18. Within the angled upper regions of the steel sheet profiles 15 and 16 protrude the edges of roof skin elements 22 into the V-shaped channel 18. The edges of the roof skin elements 22 are provided with a double-sided adhesive tape 38, which is already attached during manufacture. During assembly, the outer protective layer of such a double-sided adhesive tape 38 is removed so that a sealing tape 37 can be inserted between the edges of the roof skin elements 22, which is firmly and tightly connected to the tapes 38 by an adhesive connection. FIG. 6 also shows a holding clip 25 which has cantilevers 26 which are spread apart in a Y-shape in its upper region and which rest on the double-sided adhesive tapes 38. In its lower region, the holding clip 25 has hooks 27 which are angled outwards and which engage in the elongated holes 34 which are formed in the steel sheet profiles 15 and 16. The elongated holes 34 can be seen in particular from the illustration in FIG. 7. The holding clips 25 can be used at predeterminable distances from one another. At those points where there are no retaining clips 25, a continuous adhesive connection is created between the sealing tape 37 and the double-sided adhesive tapes 38. In the area of the V-shaped gutter, a well-sealed rain gutter is formed on the one hand by the above-described embodiment of the subject matter of the invention, and at the same time the edges of the roof skin elements are firmly anchored with the aid of the retaining clips 25.

Die Fig. 7 zeigt in einem schematischen Aufriß das Stahlblech-Profil 15 und läßt auch die oben bereits angesprochenen Langlöcher 34 deutlich erkennen. Weiterhin ist in der Fig. 7 auch die Keilnut 17 ersichtlich, welche gemäß den oberen Erläuterungen dazu dient, eine in der Fig. 2 veranschaulichte Ausklinkung herzustellen, indem.nämlich von oben quer zur Keilnut 17 Einschnitte angebracht werden und der zwischen den Einschnitten verbleibende Randbereich ausgebrochen wird.FIG. 7 shows the steel sheet profile 15 in a schematic elevation and also clearly shows the elongated holes 34 already mentioned above. 7 also shows the keyway 17, which, according to the above explanations, serves to produce a notch illustrated in FIG. 2, namely by making cuts from above across the keyway 17 and between the cuts remaining edge area is broken out.

Schließlich zeigt die Fig. 7 auch Ankörnungen 28 und 29, welche einerseits als Ablängmaß dienen und andererseits ein Bohrbild darstellen, so daß die zur Herstellung von Verbindungen erforderlichen Bohrungen ohne Bohrschablone angebracht und dabei zugleich exakt positioniert werden können. Es können auf diese Weise sowohl die Bohrungen 30 für die Verbindungsschrauben 20 als auch die Bohrungen 31 für die Verbindungsschrauben 21 leicht und präzise angebracht werden.Finally, FIG. 7 also shows punchings 28 and 29 which serve on the one hand as a cut-to-length dimension and on the other hand represent a drilling pattern, so that the bores required for making connections can be made without a drilling template and at the same time can be positioned exactly. In this way, both the bores 30 for the connecting screws 20 and the bores 31 for the connecting screws 21 can be made easily and precisely.
