Abstract

1. Ventilating element for the gutter-side sealing of a roof, consisting of a rigid but flexible synthetic material strip (2), which is provided on a longitudinal edge with comb-like projecting teeth (3), characterized in that the thickness of the teeth (3) decreases constantly towards their free ends.

Description

Die Erfindung betrifft ein Lüftungselement zum traufseitigen Abschluß von Dacheindeckungen, bestehend aus einem steifen, aber biegsamen Kunststoffstreifen, der an einem Längsrand mit kammartig abstehenden Zähnen versehen ist.The invention relates to a ventilation element for the eaves-side closure of roof coverings, consisting of a stiff but flexible plastic strip, which is provided on a longitudinal edge with teeth protruding like a comb.

Ein solches Lüftungselement ist aus der DE-OS 25 17 458 bekannt. Es ist dazu bestimmt, mit seinem Kunststoffstreifen derart an der untersten Dachlatte befestigt zu werden, daß die Zähne mit ihren Enden an der Unterseite der Dacheindeckungsplatten anliegen, so daß die kammartig abstehenden Zähne eine Gitterstruktur bilden, welche den Raum zwischen der untersten Dachlatte und den Dacheindeckungsplatten abschließt. Diese Gitterstruktur verhindert ein Eindringen von Tieren und großen Fremdkörpern in den Dachraum, ohne eine Durchlüftung des Dachraumes zu behindern.Such a ventilation element is known from DE-OS 25 17 458. It is intended to be attached with its plastic strip to the lowest roof batten in such a way that the ends of the teeth lie against the underside of the roofing panels, so that the teeth protruding like a comb form a lattice structure which closes off the space between the lowest roof batten and the roof covering panels. This lattice structure prevents animals and large foreign objects from entering the roof space without impeding ventilation of the roof space.

Infolge ihrer Profilierung haben die Dacheindeckungsplatten von der untersten Dachlatte einen längs der Dachlatte wechselnden Abstand. Das Lüftungselement muß so angebracht werden, daß auch der größte Abstand von den Zähnen überbrückt wird, so daß die Zähne im Bereich der geringeren Abstände sehr stark ausgelenkt werden. Der verwendete Kunststoff läßt zwar ein Auslenken der Zähne zu, jedoch besteht die Gefahr, daß bei sehr starker Auslenkung, wie sie bei stark profilierten Dacheindeckungsplatten vorkommt, die Zähne abgeknickt werden oder abbrechen, weil die gesamte Biegekraft an der Wurzel der Zähne auftritt, also an der Stelle, an der die Zähne in den Rand des durchgehenden Kunststoffstreifens übergehen. Diese Gefahr besteht insbesondere dann, wenn das Verlegen der Lüftungselemente bei tiefen Temperaturen erfolgt, bei denen der Kunststoff notwendig seine Elastizität verliert. Auch kann es gerade bei diesen Temperaturen nachträglich noch zu einem Brechen der Zähne kommen. Diese Gefahr ist umso größer, je dicker und damit je starrer die Zähne sind. Andererseits dürfen die Zähne nicht zu dünn ausgebildet sein, damit sie den gewünschten Schutz vor dem Eindringen von Tieren und dergleichen bieten. Insbesondere hat es auch wenig Sinn, die Zähne dünner auszubilden als die Kunststoffstreifen, weil dann gerade 82 Übergang von dem Kunststoffstreifen zu den Zähnen eine Schwachstelle entsteht, an der die Gefahr eines Abknickens oder Abbrechens der Zähne besonders groß ist.As a result of their profiling, the roof covering plates have a spacing that changes from one to the other along the roof batten. The ventilation element must be attached in such a way that even the greatest distance from the teeth is bridged, so that the teeth are very strongly deflected in the area of the smaller distances. The plastic used allows the teeth to deflect, but there is a risk that with very strong deflection, such as occurs with strongly profiled roof covering plates, the teeth will be kinked or broken off because the entire bending force occurs at the root of the teeth, i.e. on the place where the teeth merge into the edge of the continuous plastic strip. This risk exists in particular if the ventilation elements are laid at low temperatures at which the plastic necessarily loses its elasticity. Even at these temperatures, teeth can be broken later. The risk is greater the thicker and therefore the more rigid the teeth. On the other hand, the teeth must not be too thin so that they offer the desired protection against the penetration of animals and the like. In particular, it has little sense to design the teeth thinner than the plastic strip because then just 82 transition from the plastic strip to the teeth a vulnerability arises where the risk of Kinking or breaking of the teeth is particularly large.

Der Erfindung liegt die Aufgabe zugrunde, ein Lüftungselement der genannten Art so zu verbessern, daß die Gefahr eines Abknickens oder Abbrechens der Zähne praktisch ausgeschlossen ist und trotzdem ein hoher Widerstand gegen eindringende Tiere und dergleichen gewährleistet ist.The invention has for its object to improve a ventilation element of the type mentioned so that the risk of kinking or breaking off the teeth is practically excluded and still a high resistance to intruding animals and the like is guaranteed.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Dicke der Zähne in Richtung auf ihr Ende stetig abnimmt.This object is achieved according to the invention in that the thickness of the teeth decreases steadily towards its end.

Bei dem erfindungsgemäßen Lüftungselement nimmt die Flexibilität der Zähne in Richtung auf deren Enden hin zu, so daß sie ausreichend flexibel sind, um sich auch sehr stark gewellten Dacheindeckungsplatten anpassen zu können. Die Krümmung der abgelenkten Zähne verläuft jedoch zu ihren Enden hin progressiv, wodurch sowohl eine günstige Kräfteverteilung als auch eine hohe Stabilität erzielt wird. Insbesondere sind die durch das Abbiegen der Zähne im Material entstehenden Spannungen so verteilt, daß gerade an der Wurzel der Zähne keine übermäßigen Kräfte auftreten. Da hier das Material am dicksten ist, können diese Kräfte ohne weiteres aufgenommen werden, so daß eine Bruchgefahr auch unter ungünstigsten Umständen ausgeschlossen ist.In the ventilation element according to the invention, the flexibility of the teeth increases towards their ends, so that they are sufficiently flexible to be able to adapt even very strongly corrugated roofing panels. However, the curvature of the deflected teeth runs progressively towards their ends, as a result of which both a favorable distribution of forces and high stability are achieved. In particular, the stresses arising from the bending of the teeth in the material are distributed in such a way that no excessive forces occur precisely at the root of the teeth. Since the material is thickest here, these forces can easily be absorbed, so that there is no risk of breakage even under the most unfavorable circumstances.

Bei einer bevorzugten Ausführungsform der Erfindung weisen die Zähne an ihrer Wurzel die gleiche Dicke auf wie der benachbarte Kunststoffstreifen. Infolge der günstigen Kräfteverteilung kann dieser Kunststoffstreifen dünner ausgebildet sein als bisher üblich. Bei einer bevorzugten Ausführungsform der Erfindung hat der Kunststoffstreifen eine Dicke von etwa 1,5 mm, und es weisen die Zähne an ihren Enden eine Dicke von etwa 0,8 mm auf. Demgegenüber hatten bisher bekannte Lüftungselemente im allgemeinen eine Dicke von etwa 2 mm. Aus der verminderten Dicke in Verbindung mit der abnehmenden Dicke der Zähne ergibt sich eine nicht unbeträchtliche Materialersparnis, die bei der heutigen Rohstoff-Knappheit, abgesehen vom Preis, von erheblicher Bedeutung ist.In a preferred embodiment of the invention, the teeth have the same thickness at their roots as the adjacent plastic strip. As a result of the favorable distribution of forces, this plastic strip can be made thinner than previously customary. In a preferred one According to an embodiment of the invention, the plastic strip has a thickness of approximately 1.5 mm and the teeth have a thickness of approximately 0.8 mm at their ends. In contrast, previously known ventilation elements generally had a thickness of approximately 2 mm. The reduced thickness in connection with the decreasing thickness of the teeth results in a not inconsiderable material saving, which is of considerable importance in today's raw material shortage, apart from the price.

Die Zähne können sich in bekannter Weise in ihrer Ruhelage in einer gemeinsamen Ebene befinden, die mit der Ebene des Kunststoffstreifens einen stumpfen Winkel bildet. Es können jedoch in bestimmten Fällen auch völlig ebene Lüftungselemente sowie Lüftungselemente Anwendung finden, bei denen die Zähne in ihrer Ruhelage mit der Ebene des Kunststoffstreifens einen rechten oder sogar spitzen Winkel bilden.The teeth can be in a known manner in their rest position in a common plane which forms an obtuse angle with the plane of the plastic strip. In certain cases, however, completely flat ventilation elements and ventilation elements can also be used, in which the teeth in their rest position form a right or even acute angle with the plane of the plastic strip.

Die Erfindung wird im folgenden anhand des in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben und erläutert. Die der Beschreibung und der Zeichnung zu entnehmenden Merkmale können bei anderen Ausführungsformen der Erfindung einzeln für sich oder zu mehreren in beliebiger Kombination Anwendung finden. Es zeigen

  • Fig. 1 eine Draufsicht auf einen Abschnitt eines Lüftungselementes nach der Erfindung in Richtung des Pfeiles I in Fig. 2 und
  • Fig. 2 einen Schnitt durch das Lüftungselement nach Fig. 1 längs der Linie II-II.
The invention is described and explained in more detail below with reference to the embodiment shown in the drawing. The features to be gathered from the description and the drawing can be used in other embodiments of the invention individually or in combination in any combination. Show it
  • Fig. 1 is a plan view of a portion of a ventilation element according to the invention in the direction of arrow I in Fig. 2 and
  • Fig. 2 shows a section through the ventilation element of FIG. 1 along the line II-II.

Das in der Zeichnung dargestellte Lüftungselement besteht aus einem im Querschnitt winkelförmigen Kunststoffprofil 1, das beispielsweise durch Strangpressen hergestellt werden kann. Der eine Schenkel des Profils bildet einen Kunststoffstreifen 2 gleichförmiger Dicke d, während der andere Schenkel eine Kammstruktur bildet, deren Zähne 3 sich an einen Längsrand des Kunststoffstreifens 1 anschließen. Die Zähne 3 haben am Übergang zum Kunststoffstreifen 2 die gleiche Dicke d wie dieser Kunststoffstreifen, nehmen jedoch in Richtung auf ihr Ende in ihrer Dicke stetig ab, so daß sie dort nur noch eine Dicke e haben, die annähernd halb so groß ist wie die Dicke d an ihrer Wurzel 4. Bei dem dargestellten Ausführungsbeispiel beträgt die Dicke des Kunststoffstreifens 2 d=1,5 mm, und die Dicke am Ende der Zähne 3 e=0,8 mm.The ventilation element shown in the drawing consists of a cross-sectionally angular plastic profile 1, which can be produced for example by extrusion. One leg of the profile forms a plastic strip 2 of uniform thickness d, while the other leg forms a comb structure, the teeth 3 of which adjoin a longitudinal edge of the plastic strip 1. The teeth 3 at the transition to the plastic strip 2 have the same thickness d as this plastic strip, but decrease steadily in thickness towards their end, so that there they only have a thickness e which is approximately half the thickness d at its root 4. In the illustrated embodiment, the thickness of the plastic strip is 2 d = 1.5 mm, and the thickness at the end of the teeth 3 e = 0.8 mm.

Das erfindungsgemäße Lüftungselement wird zum t.raufseitigen Abschluß von Dacheindeckungen mit dem Kunststoffstreifen 2 auf die den Dacheindeckungsplatten zugewandte Oberseite der untersten Dachlatte derart befestigt, daß die Zähne 3 schräg gegen die Unterseite der Dacheindeckungsplatten gerichtet sind. Die Zähne bilden bei dem dargestellten Ausführungsbeispiel mit der Senkrechten 6 zur Oberseite des Kunststoffstreifens 2 einen Winkel oC,= 35°. Bei diesem Winkel und der gewählten Länge ist gewährleistet, daß die Zähne 3 in jedem Fall an der Unterseite der Dacheindeckungsplatten zur Anlage kommen und dabei elastisch mehr oder weniger zurückgebogen werden. Infolge der zu ihrem Ende abnehmenden Dicke der Zähne 3 erfolgt die Auslenkung der Zähne 3 in Richtung auf ihr Ende in progressiver Weise, wodurch beträchtliche Auslenkungen möglich sind, ohne daß einerseits die Zähne insgesamt zu schwach ausgebildet werden müßten und andererseits die im Bereich der Wurzel 4 entstehenden Biegekräfte so stark werden können, daß ein Abknicken oder Abbrechen einzelner Zähne zu befürchten wäre. Es ergeben sich auf diese Weise optimale Verhältnisse, die eine sehr hohe Stabilität des Lüftungselementes bei relativ geringer Wandstärke gewährleisten.The ventilation element according to the invention is attached to the t.raufseiten completion of roof coverings with the plastic strip 2 on the roof covering panels facing the top of the lowest roof batten such that the teeth 3 are directed obliquely against the underside of the roof covering panels. In the exemplary embodiment shown, the teeth form an angle oC = 35 ° with the perpendicular 6 to the upper side of the plastic strip 2. With this angle and the selected length, it is ensured that the teeth 3 always come to rest on the underside of the roofing panels and are more or less bent back elastically. As a result of the decreasing thickness of the teeth 3 towards their end, the deflection of the teeth 3 towards their end takes place in a progressive manner, whereby considerable deflections are possible without the teeth overall having to be made too weak on the one hand and those in the area of the root 4 on the other hand arising bending forces can become so strong that a There would be fear of kinking or breaking off individual teeth. This results in optimal conditions which ensure a very high stability of the ventilation element with a relatively small wall thickness.

Zum Befestigen der Lüftungselemente kann der Kunststoffstreifen 2 mit in Abständen angebrachten Nagellöchern 5 versehen sein. Weitere Löcher können den Durchtritt von Befestigungsschrauben für Dacheindeckungsplatten aus Asbestzement oder dergleichen ohne Beschädigung des Lüftungselementes gestatten.To attach the ventilation elements, the plastic strip 2 can be provided with nail holes 5 arranged at intervals. Additional holes can allow fastening screws for roofing panels made of asbestos cement or the like to pass through without damaging the ventilation element.

Das Lüftungselement, von dem in Fig. 1 nur ein Abschnitt dargestellt ist, kann in beliebigen Längen hergestellt werden. Als für die Praxis geeignet haben sich Abschnitte von jeweils 1 m Länge erwiesen. Es versteht sich jedoch, daß auch Lüftungselemente anderer Längen verwendbar sind und sogar eine Konfektionierung des Lüftungselementes in Form aufgerollter Bänder denkbar ist.The ventilation element, only a section of which is shown in FIG. 1, can be produced in any lengths. Sections of 1 m in length have proven to be suitable in practice. However, it goes without saying that ventilation elements of other lengths can also be used and that the ventilation element can even be assembled in the form of rolled-up strips.

Es versteht sich, daß die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt ist. Insbesondere sind Variationen bezüglich der Breite des Kunststoffstreifens und der Länge der Zähne, der Breite der Zähne und des Abstandes zwischen den Zähnen und der Materialdicke und der Dickevariation der Zähne möglich. Dabei können diese Größen bestimmten Anwendungszwecken angepaßt werden, beispielsweise um der Forderung nach einer optimalen Anpassung für bestimmte Arten der Dacheindeckung oder aber nach größtmöglicher Universalität zu genügen.It is understood that the invention is not limited to the illustrated embodiment. In particular, variations in the width of the plastic strip and the length of the teeth, the width of the teeth and the distance between the teeth and the material thickness and the thickness variation of the teeth are possible. These sizes can be adapted to specific applications, for example to meet the requirement for an optimal adaptation for certain types of roofing or for the greatest possible universality.
