Description
Die Erfindung betrifft ein vorgefertigtes Dachverschalungselement, bestehend aus einer auf der Dachkonstruktion zu verlegenden Platte, die an ihrer Oberseite senkrecht zur Traufe verlaufende, ein Auflager für die Dachlatten bildende Versteifungsleisten aufweistThe invention relates to a prefabricated roof cladding element, consisting of a plate to be laid on the roof structure, which is attached to its Stiffening strips that run perpendicular to the eaves and form a support for the roof battens having
Will man bei einem bekannten Dachverschalungselement dieser Art (N L 68 702) eine Wärmedämmung erzielen, so muß man die Platte aus wärmeisolierendem Material herstellen. Da bei derartigen Dachverschalungselementen außerdem die Forderung nach Begehbarkeit besteht, muß die Platte auch eine entsprechende Festigkeit besitzen, d. h, das Plattenmaterial muß eine bestimmte Dichte aufweisen. Eine erhöhte Dichte vermindert jedoch die Wärmedämmeigenschaften. Die Erfüllung beider Forderungen, nämlich die der Wärmeisolierung und die der Begehbarkeit führt also zu einem Kompromiß, der nicht immer erwünscht ist.If you want thermal insulation in a known roof cladding element of this type (N L 68 702) achieve, so you have to make the plate of heat insulating material. As with such roof cladding elements In addition, there is a requirement that it can be walked on, the plate must also have a corresponding one Have strength, d. That is, the plate material must have a certain density. An increased density however, reduces the thermal insulation properties. The fulfillment of both requirements, namely that of thermal insulation and that of accessibility leads to a compromise that is not always desirable.
Man könnte nun zwischen die Versteifungsleisten vorgefertigte Wärmedämmplatten einlegen oder sogar einkleben, wie dies bei einem anderen Dachverschalungselement bekannt ist (FR 9 79 943). Dies würde jedoch zu einer teueren und zeitaufwendigen Herstellung führen, und zwar insbesondere im Hinblick darauf, daß die Wärmedämmplatten sehr genau an den Abstand zwischen den Versteifungsleisten angepaßt werden müssen.You could now insert or even insert prefabricated thermal insulation panels between the stiffening strips Glue in, as is known from another roof cladding element (FR 9 79 943). This would however, lead to an expensive and time-consuming production, in particular with a view to that the thermal insulation panels are adapted very precisely to the distance between the stiffening strips have to.
Die der Erfindung zugrundeliegende Aufgabe besteht somit darin, ein vorgefertigtes Dachverschalungselement der in Frage stehenden Art so auszubilden, daß es bei ausreichender Wärmedämmung und Begehbarkeit besonders einfach herzustellen istThe object on which the invention is based is thus to provide a prefabricated roof cladding element of the type in question so that it is adequately insulated and accessible is particularly easy to manufacture
Diese Aufgabe wird nach der Erfindung dadurch gelöst daß zwischen dan Versteifungsleisten auf die Platte ein bei Raumtemperatur härtender Schaumkunststoff aufgeschäumt ist, der eine geringere Dicke aufweist als die Versteifungsleisten und an deren Seitenflächen bis zu deren Oberseiten hochgezogen ist Das erfindungsgemäß ausgebildete Dachverschalungselement genügt sämtlichen gestellten Anforderungen. Die Wahl des Plattenmaterials und dessen Stärke erfolgt im Hinblick auf die gewünschte Trittfestigkeit Die Wärmedämmeigenschaften hingegen werden von dem Schaumkunststoff bestimmt Eine Auslegung des Elements nach seiner Trittfestigkeit beeinträchtigt also nicht seine Wärmedämmeigenschaften oder umgekehrt Dennoch ergibt sich eine sehr einfache VorfertigungThis object is achieved according to the invention in that between the stiffening strips on the Plate is a foam plastic that cures at room temperature and has a smaller thickness has than the stiffening strips and is pulled up on their side surfaces up to their tops The roof cladding element designed according to the invention meets all the requirements. The choice of sheet material and its thickness is made with regard to the desired resistance to treading The thermal insulation properties, however, are determined by the foam plastic Elements according to its crush resistance does not affect its thermal insulation properties or vice versa Nevertheless, the prefabrication is very simple
innerhalb des Werkes, die auch von ungeschultem Personal vorgenommen werden kann. Die Platten, die vor allem aus Fasermaterial bestehen können, lassen sich kontinuierlich oder als zusammenhängende Bahn unter einer Anzahl von Sprühdüsen hindurchführen, welche das Reaktionsgemisch für den Schaumkunststoff, bei dem es sich insbesondere um Polyurethanschaum handelt, aufsprühen. Anschließend erfolgt ein freies Aufschäumen. Die Sprühdüsen sind so gerichtet, oaß die Seitenflächen der Versteifungsleisten bedeckt werden. Man vermindert auf diese Weise die Auswirkungen von Kältebrücken im Bereich der Versteifungsleisten. Die oberen Flächen der Versteifungsleisten bleiben frei, um ein anschließendes Nacharbeiten zu vermeiden.within the plant, which can also be carried out by untrained personnel. The panels that Above all, they can consist of fiber material, can be continuous or as a coherent web pass under a number of spray nozzles, which the reaction mixture for the foam plastic, which is in particular polyurethane foam, spray on. Then a free foaming. The spray nozzles are directed so that the side surfaces of the stiffening strips are covered will. In this way, the effects of cold bridges in the area of the stiffening strips are reduced. The upper surfaces of the stiffening strips remain free for subsequent reworking avoid.
Die spätere Montage bietet ebenfalls keine Schwierigkeiten, da die vorgefertigten Dachverschalungselemente lediglich zur Baustelle transportiert und dort auf die Dachkonstruktion aufgelegt werden müssen.The later assembly does not present any difficulties either, because the prefabricated roof cladding elements are only transported to the construction site and placed there the roof structure must be placed.
Die Zeichnung zeigt einen Querschnitt durch ein erfindungsgemäß ausgebildetes, vorgefertigtes Dachverschalungselement The drawing shows a cross section through a prefabricated roof cladding element designed according to the invention
Eine auf der Dachkonstruktion zu verlegende Platte 1 trägt auf ihrer Oberseite senkrecht zur Traufe verlaufende, ein Auflager für die Dachlatten bildende Versteifungsleisten 2. Zwischen diesen Versteifungsleisten 2 ist ein bei Raumtemperatur härtender Schaumkunststoff 3, im vorliegenden Falle Polyurethanschaum, frei aufgeschäumt Der Schaumkunststoff 3 weist eine geringere Dicke als die Versteifungsleisten 2 auf und ist an deren Seitenflächen 4 bis zu deren Oberseiten hochgezogen.A plate 1 to be laid on the roof structure carries on its upper side perpendicular to the eaves running stiffening strips forming a support for the roof battens 2. Between these stiffening strips 2 is a foam plastic 3 that hardens at room temperature, in the present case polyurethane foam, freely foamed The foam plastic 3 has a smaller thickness than the stiffening strips 2 and is pulled up on their side surfaces 4 up to their tops.
