Definitions
- the invention relates to a panel element for the production of building roofs consisting of a sandwich panel and a longitudinal member arranged and fastened in the region of a longitudinal end face thereof, the sandwich panel being constructed from a rigid foam plastic panel, in particular made of polystyrene, and a lower and upper cover panel glued onto it
- Side 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 engages in a corresponding longitudinal groove provided in the rigid foam plastic plate, and wherein the rigid foam plastic plate on its other longitudinal end face has a corresponding longitudinal groove for the upper flange part of the I-profile of an adjacent plate element having.
- the longitudinal beam which is part of the load-bearing structure, or the I-profile is constructed 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 crossbars under them. All of this is relatively complex.
- the invention has for its object to make a plate element of the type mentioned easier to manufacture while maintaining the static requirements.
- the present invention teaches that the I-section consists of a steel sheet formed by cold rolling or cold drawing and that its upper flange is arranged at a distance from the upper cover plate.
- An I-profile made of sheet steel formed by cold rolling or cold drawing is considerably easier and cheaper to manufacture than an I-profile made of glued and optionally finger-jointed 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 deflection 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. So the lower flange of the I-profile can be made regularly so small that it is no longer necessary to put crossbars underneath, because the sandwich panels lie on crossbeams of the load-bearing structure after 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.
- the I-profile has a sheet metal doubling only in the area of its two flanges; in other words, the starting steel sheet is formed by double the sole in the area of the flanges, while the web has only a single sheet thickness. This reduces the resistance to bending in the transverse direction, but is of secondary importance in the present case because it relies on the transverse strength in connection with adjacent plate elements does not arrive.
- the invention recommends that the arrangement be such that 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 material, as sealing insulating agent will work with polyurethane foam; In this way, the tightness of the roof formed from plate elements according to the invention is ensured.
- 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, in particular made 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 member 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, provided in the rigid foam plastic plate 4 engages longitudinal groove 10.
- the rigid foam plastic plate 4 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.
- 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, l2 or the upper flange 13 of the associated I-profile.

Abstract
Description
Die Erfindung betrifft 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 Hartschaumkunststoffplatte und einer auf diese aufgeklebten unteren sowie oberen Deckplatte aufgebaut ist und der Längsträger aus einem I-Profil besteht, auf dessen der Hartschaumkunststoffplatte zugewandtem 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.The invention relates to a panel element for the production of building roofs consisting of a sandwich panel and a longitudinal member arranged and fastened in the region of a longitudinal end face thereof, the sandwich panel being constructed from a rigid foam plastic panel, in particular made of polystyrene, and a lower and upper cover panel glued onto it Side 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 engages in a corresponding longitudinal groove provided in the rigid foam plastic plate, and wherein the rigid foam plastic plate on its other longitudinal end face has a corresponding longitudinal groove for the upper flange part of the I-profile of an adjacent plate element having.
Bei einem aus der Praxis bekannten Plattenelement der genannten Art ist der Längsträger, der Teil der tragenden Kunstruktion ist, bzw. das I-Profil aus drei Holzleisten rechteckigem 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.In a plate element of the type mentioned which is known in practice, the longitudinal beam, which is part of the load-bearing structure, or the I-profile is constructed 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 crossbars under them. All of this is relatively complex.
Der Erfindung liegt die Aufgabe zugrunde, ein Plattenelement der eingangs genannten Art unter Beibehaltung der statischen Erfordernisse einfacher herstellbar zu machen.The invention has for its object to make a plate element of the type mentioned easier to manufacture while maintaining the static requirements.
Zur Lösung dieser Aufgabe lehrt die vorliegende Erfindung, daß das I-Profil aus einem durch Kaltwalzen oder Kaltziehen umgeformten Stahlblech besteht und sein oberer Flansch mit Abstand von der oberen Deckplatte angeordnet ist.To achieve this object, the present invention teaches that the I-section consists of a steel sheet formed by cold rolling or cold drawing and that its upper flange is arranged at a distance from the upper cover plate.
Ein I-Profil aus durch Kaltwalzen oder Kaltziehen umgeformtem Stahlblech ist erheblich einfacher und kostengünstiger herstellbar als ein I-Profil aus zusammengeleimten und gegebenenfalls 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 Durchbiegung in Längsrichtung des Plattenelementes kann das I-Profil aus dem umgeformten Stahlblech in den Querschnittsabmessungen erheblich kleiner gemacht werden. So wird der untere Flansch des I-Profils regelmäßig so klein gemacht werden können, daß es unterzulegender Querleisten nicht mehr bedarf, weil sich die Sandwichplatten nach geringer Durchbiegung auf Querträger der tragenden Konstruktion auflegen. 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.An I-profile made of sheet steel formed by cold rolling or cold drawing is considerably easier and cheaper to manufacture than an I-profile made of glued and optionally finger-jointed 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 deflection 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. So the lower flange of the I-profile can be made regularly so small that it is no longer necessary to put crossbars underneath, because the sandwich panels lie on crossbeams of the load-bearing structure after 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.
Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So weist nach einer bevorzugten Ausführungsform das I-Profil nur im Bereich seiner beiden Flansche eine Blechdoppelung auf; mit anderen Worten ist das Ausgangsstahlblech durch alleinige Doppelung im Bereich der Flansche gebildet, während der Steg nur einfache Blechdicke aufweist Das reduziert zwar die Festigkeit gegen Durchbiegungen in Querrichtung, ist im vorliegenden Fall aber von untergeordneter Bedeutung weil es auf die Querfestigkeit im Verbund mit benachbarten Plattenelementen nicht ankommt. Im übrigen empfiehlt die Erfindung, die Anordnung so zu treffen, daß zumindest eine der beiden Längsstirnflächen oberhalb der Längsnut zur Bildung eines mit Isoliermittel verfüllbaren Längsspaltes zurückversetzt ist, als abdichtendes Isoliermittel wird man insoweit mit Polyurethanschaum arbeiten; auf diese Weise ist die Dichtigkeit des aus erfindungsgemäßen Plattenelementen gebildeten Daches sichergestellt.There are several possibilities for the further configuration within the scope of the invention. Thus, according to a preferred embodiment, the I-profile has a sheet metal doubling only in the area of its two flanges; in other words, the starting steel sheet is formed by double the sole in the area of the flanges, while the web has only a single sheet thickness.This reduces the resistance to bending in the transverse direction, but is of secondary importance in the present case because it relies on the transverse strength in connection with adjacent plate elements does not arrive. In addition, the invention recommends that the arrangement be such that 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 material, as sealing insulating agent will work with polyurethane foam; In this way, the tightness of the roof formed from plate elements according to the invention is ensured.
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
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, l2 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
