Abstract

A panel for constructing building roofs comprising a sandwich panel (1) and a longitudinal beam (2), arranged and fastened in the region of one longitudinal end face (3) of the said sandwich panel. The sandwich panel (1) is made up of a rigid foam plastic panel (4), consisting in particular of polystyrene, and a lower cover panel (5) and upper cover panel (5) adhesively attached to the latter. The longitudinal beam (2) comprises an I section, on the lower flange part (7) of which, facing the rigid foam plastic panel (4), the sandwich panel (1) rests with its lower cover panel (5), the web (8) of the said I section bears against the longitudinal end face (3) of the rigid foam plastic panel (1) and its upper flange part (9), facing the rigid foam plastic panel (1), engages in a corresponding longitudinal groove (10) provided in the rigid foam plastic panel (4). Furthermore, the rigid foam plastic panel (4) has on its other longitudinal end face (11) a corresponding longitudinal groove (12) for the upper flange part (9) of the I section of a neighbouring panel. Production is made easier here if the I section (2) comprises a steel sheet shaped by cold rolling or cold drawing and its upper flange (13) is arranged at a distance from the upper cover panel (6). <IMAGE>

Description

Die Erfindung betrifft eine Platte mit einem im Bereich von deren einer Längsstirnfläche angeordneten Längsträger in Form eines aus einem durch Kaltwalzen oder Kaltziehen umgeformten, nur im Bereich seiner beiden Flausche gedoppelten Stahlblech bestehenden I-Profils, auf dessen unteren Flanschteil die Platte mit ihrer unteren Fläche aufliegt und dessen Steg an der Längsstirnfläche der Platte anliegt.The invention relates to a plate with a longitudinal member arranged in the area of its longitudinal end face in the form of an I-profile formed from a sheet steel formed by cold rolling or cold drawing and only doubled in the area of its two flanges, on the lower flange part of which the plate rests with its lower surface and whose web rests on the longitudinal face of the plate.

Eine bekannte Platte der genannten Art (FR-A-2 251 681) ist nicht für die Herstellung von Gebäudedächern, sondern von Decken- und Wandvekleidungen bestimmt. Die den Platten zugeordneten Längsträger sind getrennte Bauteile. Die Höhe des Längsträgersteges entspricht der Dicke der Platten, die zwischen den Flanschen einfassen und aus einem beliebigen Material hergestellt sein können. Für die Herstellung von Gebäudedächern ist die beschriebene Konstruktion nicht vorgesehen und auch nicht geeignet, weil keine Dichtigkeit gegeben ist und die sich von außen nach innen erstreckenden Längsträger hervorragende Kältebrücken bilden, die unerwünschte Kondenswasserprobleme nach sich ziehen.A known plate of the type mentioned (FR-A-2 251 681) is not intended for the production of building roofs, but rather for ceiling and wall coverings. The side members assigned to the panels are separate components. The height of the longitudinal girder web corresponds to the thickness of the plates that surround between the flanges and can be made of any material. The construction described is not intended and also not suitable for the production of building roofs, because there is no tightness and the longitudinal members extending from the outside inward form excellent cold bridges which result in undesirable condensation problems.

Bei einer anderen bekannten Wandverkleidung (DE-A-1 683 494) aus Platten und I-Profillängsträgers, bei denen auch der Steg des I-Profils gedoppelt ist und die beiden Stegabschnitte einen Abstand voneinander aufweisen, hat man die Anordnung auch schon so getroffen, daß der "obere" Profilflansch mit Abstand von der "Außenseite" angeordnet ist und mit seinen beiden Teilen in Länsnuten benachbarte Platten einfaßt, deren Längsstirnflächen unter Bildung eines Längspaltes zurückversetzt sind. Der Längsspalt ist hier zu dem Zweck vorgesehen, Abmessungsänderungen der Platten aufnehmen zu können. Bei einer weiteren bekannten, der unmittelbar zuvor erörteten Wandverkleidung, vergleichbaren Wandverkleidung, bei der die Platten aus kacheln bestehen, sind die Fugen zwischen den Kacheln natürlich gefugt.In the case of another known wall covering (DE-A-1 683 494) made of plates and I-profile side members, in which the web of the I-profile is also doubled and the two web sections are spaced apart, the arrangement is also available already made so that the "upper" profile flange is arranged at a distance from the "outside" and encloses with its two parts in longitudinal grooves adjacent plates, the longitudinal end faces of which are set back to form a longitudinal gap. The longitudinal gap is provided here for the purpose of being able to accommodate changes in the dimensions of the plates. In a further known wall covering comparable to that discussed immediately above, in which the panels consist of tiles, the joints between the tiles are naturally grouted.

Aus der Praxis bekannt ist ferner ein Plattenelement für die Herstellung von Gebäudedächern, bestehend aus einer Sandwichplatte und einem im Bereich von deren einer Längsstirnfläche angeordneten sowie befestigten Längsträger, wobei die Sandwichplatte aus einer insbesondere aus Polystyrol bestehenden Hertschaumkunststoffplatte und einer auf diese aufgeklebten unteren sowie oberen Deckplatte aufgebaut ist und der Längsträger aus einem I-Profil besteht, auf dessen der Hartschaumkunststoffplatte zugewandten unteren Flanschteil die Sandwichplatte mit ihrer unteren Deckplatte aufliegt, dessen Steg an der Längsstirnfläche der Hartschaumkunststoffplatte anliegt und dessen der Hartschaumkunststoffplatte zugewandter oberer Flanschteil in eine entsprechende, in der Hartschaumkunststoffplatte vorgesehene Längsnut eingreift, und wobei die Hartschaumkunststoffplatte an ihrer anderen Längsstirnfläche eine entsprechende Längsnut für das obere Flanschteil des I-Profils eines benachbarten Plattenelementes aufweist. Der Längsträger, der Teil der tragenden Konstruktion ist, bzw. das I-Profil ist hier aus drei Holzleisten rechteckigen Querschnittes aufgebaut, die die beiden Flansche und den Steg des I-Profils bilden. Die gegebenenfalls keilverzinkten Holzleisten sind untereinander und mit der zugeordneten Sandwichplatte verklebt. Da solche Plattenelemente verhältnismäßig große Längen von fünf bis sechs Metern besitzen, weisen auch die Profilstege zur Vermeidung einer zu großen Längsdurchbiegung eine verhältnismäßig große Höhe auf; infolgedessen kann es auch zwischen den Längsträgern benachbarter Plattenelemente zu Querdurchbiegungen der Sandwichplatte kommen, die durch Unterlegen von Querhölzern zu unterbinden sind. Alles das ist verhältnismäßig aufwendig.A plate element for the production of building roofs is also known from practice, consisting of a sandwich plate and a longitudinal member arranged and fastened in the area of its longitudinal end face, the sandwich plate consisting of a rigid foam plastic plate, in particular made of polystyrene, and a lower and upper cover plate glued onto it is constructed and the longitudinal member consists of an I-profile, on the lower flange part facing the rigid foam plastic plate, the sandwich plate rests with its lower cover plate, the web rests on the longitudinal end face of the rigid foam plastic plate and the upper flange part facing the rigid foam plastic plate in a corresponding one provided in the rigid foam plastic plate Longitudinal groove engages, and wherein the hard foam plastic plate on its other longitudinal end face a corresponding longitudinal groove for the upper flange part of the I-profile of an adjacent one n plate element. The Longitudinal beam, which is part of the load-bearing structure, or the I-profile is constructed here from three wooden strips of rectangular cross-section, which form the two flanges and the web of the I-profile. The optionally finger-galvanized wooden strips are glued to one another and to the assigned sandwich panel. Since such plate elements have relatively large lengths of five to six meters, the profile webs also have a relatively large height to avoid excessive longitudinal deflection; As a result, transverse deflections of the sandwich panel can also occur between the longitudinal beams of adjacent panel elements, which can be prevented by placing cross members under them. All of this is relatively complex.

Der Erfindung liegt die Aufgabe zugrunde, die Platte der eingangs genannten Art bei einfacher Herstellbarkeit für den Einsatz in Gebäudedächern geeignet zu machen.The invention has for its object to make the plate of the type mentioned suitable for use in building roofs with simple manufacturability.

Hierzu lehrt die Erfindung, daß bei einem Einsatz als Plattenelement für die Herstellung von Gebäudedächern die Platte als Sandwichplatte aus einer insbesondere aus Polystyrol bestehenden Hartschaumkunststoffplatte und einer auf diese aufgeklebten unteren sowie oberen Deckplatte aufgebaut ist und der aus dem I-Profil bestehende Längsträger an der Sandwichplatte befestigt ist, wobei der obere Flansch des I-Profils mit Abstand von der oberen Deckplatte angeordnet ist, der der Hartschaumkunststoffplatte zugewandte obere Flanschteil in eine entsprechende, in der Hartschaumkunststoffplatte vorgesehene Längsnut einfaßt, die Hartschaumkunststoffplatte an ihrer anderen Längsstirnfläche in eine entsprechende Längsnut für das obere Flanschteil des I-Profils eines benachbarten Plattenelementes aufweist und zumindest eine der beiden Lägsstirnflächen oberhalb der Längsnut zur Bildung eines mit Isoliermittel verfüllbaren Längsspaltes zurückversetzt ist.For this purpose, the invention teaches that when used as a plate element for the production of building roofs, the plate is constructed as a sandwich plate from a rigid foam plastic plate, in particular made of polystyrene, and a lower and upper cover plate glued to it, and the longitudinal member consisting of the I-profile on the sandwich plate is attached, the upper flange of the I-profile being arranged at a distance from the upper cover plate, which surrounds the upper flange part facing the rigid foam plastic plate in a corresponding longitudinal groove provided in the rigid foam plastic plate, the rigid foam plastic plate on its other longitudinal end face in a corresponding longitudinal groove for the upper Has flange part of the I-profile of an adjacent plate element and at least one of the two longitudinal end faces above the longitudinal groove is set back to form a longitudinal gap which can be filled with insulating agent.

Die durch das erfindungsgemäße Bauelement erreichten Vorteile sind darin zu sehen, daß es einfach und billig herstellbar ist, gleichwohl aber zu Gebäudedächern führt, die in statischer und klimateschnischer Hinsicht allen Anforderungen genügen. Das erfindungsgemäße Bauelement hat sich jedenfalls in der Praxis bestens bewährt. Die Erfindung nutzt jedenfalls die Erkenntnis, daß ein I-Profil aus durch Kaltwalzen oder Kaltziehen umgeformten, nur im Bereich seiner beiden Flansche gedoppelten Stahlblech erheblich einfacher und kostengünstiger herstellbar ist als ein I-Profil aus zusammengeleimten und ggf. keilverzinkten Holzleisten. Da das I-Profil mit seinem oberen Flanschteil in die Hartschaumkunststoffplatte eingebettet und mit letzterer verbunden ist, ergibt sich eine höhere Festigkeit, so daß die Plattenelemente nunmehr mit größerer Länge hergestellt werden können. Für gleiche Festigkeit gegen Durchbiegungen in Längsrichtung des Plattenelementes kann das I-Profil aus dem umgeformten Stahlblech in den Querschnittsabmessungen erheblich kleiner gemacht werden. Insofern wird es unerzulegender Querleisten nich mehr bedürfen, weil sich die Sandwichplatten nach geringer Durchbiegung auf Querträger der tragenden Konstruktion auflegen können. Darüber hinaus ist die Steghöhe des I-Profils aus dem umgeformten Stahlblech erheblich geringer als bei einer entsprechenden Holzausführung, so daß Kältebrücken bzw. Kondensprobleme nicht vorkommen. Zudem erlaubt die oberhalb des oberen Flansches zwischen benachbarten Elementen freibleibende Längsnut ein zuverlässiges Verfüllen mit einem Isoliermittel, so daß ohne großen Aufwand auch Dichtheit eines Elementenverbandes ermöglicht wird.The advantages achieved by the component according to the invention can be seen in the fact that it is simple and inexpensive to produce, but nevertheless leads to building roofs which meet all requirements in terms of static and climatic technology. The component according to the invention has proven itself in practice in any case. In any case, the invention makes use of the knowledge that an I-profile made of sheet steel that has been formed by cold rolling or cold drawing and is only doubled in the area of its two flanges is considerably easier and cheaper to produce than an I-profile made of glued and possibly finger-galvanized wooden strips. Since the I-profile is embedded with its upper flange part in the rigid foam plastic plate and connected to the latter, there is a higher strength, so that the plate elements can now be made with a greater length. For the same strength against bending in the longitudinal direction of the plate element, the I-profile can be made considerably smaller in the cross-sectional dimensions from the formed steel sheet. Insofar as it is no longer necessary to add crossbars because the sandwich panels can lie on crossbeams of the load-bearing structure after a slight deflection. In addition, the web height of the I-profile made of the formed steel sheet is considerably lower than with a corresponding wooden version, so that cold bridges or condensation problems do not occur. In addition, the longitudinal groove remaining free between adjacent elements above the upper flange permits reliable filling with an insulating agent, so that tightness of an element assembly is also possible without great effort.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung erläutert, deren einzige Figur ein Plattenelement zeigt.In the following the invention will be explained with reference to a drawing representing an embodiment, the only figure of which shows a plate element.

Das Plattenelement ist für die Herstellung von Gebäudedächern bestimmt. Der Verband zweier Plattenelemente ist in der Figur angedeutet. Das Plattenelement besteht in seinem grundsätzlichen Aufbau aus einer Sandwichplatte 1 und einem Längsträger 2, der Teil der tragenden Konstruktion ist und im Bereich einer der beiden Längsstirnflächen 3 der Sandwichplatte 1 angeordnet sowie mit dieser verklebt ist. Die Sandwichplatte 1 ist ihrerseits aus einer insbesondere aus Polystyrol bestehenden Hartschaumkunststoffplatte 4 und einer unteren Deckplatte 5 sowie einer oberen Deckplatte 6 aufgebaut. Die untere Deckplatte 5 und die obere Deckplatte 6 sind auf die Hartschaumkunststoffplatte 4 aufgeklebt. Der Längsträger 2 besteht aus einem I-Profil, auf dessen der Hartschaumkunststoffplatte 4 zugewandtem unteren Flanschteil 7 die Sandwichplatte 1 mit ihrer unteren Deckplatte 5 aufliegt, dessen Steg 8 an der Längsstirnfläche 3 der Hartschaumkunststoffplatte 1 anliegt und dessen der Hartschaumkunststoffplatte 1 zugewandter oberer Flanschteil 9 in eine entsprechende, in der Hartschaumkunststoffplatte 4 vorgesehene Längsnut 10 eingreift. An ihrer Längsstirnfläche 11 weist die Hartschaumkunststoffplatte 4 eine entsprechende Längsnut 12 für das obere Flanschteil 9 des I-Profils eines benachbarten Profilelementes auf.The plate element is intended for the production of building roofs. The association of two plate elements is indicated in the figure. The basic structure of the plate element consists of a sandwich plate 1 and a longitudinal beam 2, which is part of the load-bearing structure and is arranged in the region of one of the two longitudinal end faces 3 of the sandwich plate 1 and is glued to it. The sandwich panel 1 is in turn made up of a rigid foam plastic panel 4 consisting in particular of polystyrene and a lower cover panel 5 and an upper cover panel 6. The lower cover plate 5 and the upper cover plate 6 are glued to the rigid foam plastic plate 4. The longitudinal beam 2 consists of an I-profile, on the lower flange part 7 facing the rigid foam plastic plate 4, the sandwich plate 1 rests with its lower cover plate 5, the web 8 of which rests on the longitudinal end face 3 of the rigid foam plastic plate 1 and the upper flange part 9 facing the rigid foam plastic plate 1 a corresponding longitudinal groove 10 provided in the rigid foam plastic plate 4 engages. On its longitudinal end face 11, the rigid foam plastic plate 4 has a corresponding longitudinal groove 12 for the upper flange part 9 of the I-profile of an adjacent profile element.

Das I-Profil besteht aus einem durch Kaltwalzen oder Kaltziehen umgeformten Stahlblech. Es ist durch Blechdoppelung nur im Bereich seiner beiden Flansche 13, 14 erzeugt, d. h. im Bereich des Steges 8 weist das I-Profil nur einfache Blechdicke auf. Im übrigen erkennt man in der Figur, daß der obere Flansch 13 des I-Profils mit Abstand von der oberen Deckplatte 6 angeordnet ist. Zumindest die eine 3 der beiden Längsstirnflächen 3, 11 ist oberhalb der Längsnut 10 bzw. 12 zurückversetzt, so daß zwischen benachbarten Plattenelementen oberhalb der Längsnuten 10, 12 bzw. des oberen Flansches 13 des zugeordneten I-Profils ein Längsspalt 15 gebildet ist. Dieser Längsspalt 15 ist zur Abdichtung und zur Vermeidung einer Kältebrücke mit Isoliermittel, beispielsweise Polyurethanschaum, abzudichten.The I-profile consists of a steel sheet formed by cold rolling or cold drawing. It is produced by sheet metal doubling only in the area of its two flanges 13, 14, ie in the area of the web 8, the I-profile has only a single sheet thickness. Otherwise you can see in the figure that the upper flange 13 of the I-profile is arranged at a distance from the upper cover plate 6. At least one 3 of the two longitudinal end faces 3, 11 is set back above the longitudinal groove 10 or 12, so that a longitudinal gap 15 is formed between adjacent plate elements above the longitudinal grooves 10, 12 or the upper flange 13 of the associated I-profile. This longitudinal gap 15 is to be sealed with an insulating agent, for example polyurethane foam, to seal and avoid a cold bridge.
