Description

gestellten Schnittzeichnung von zwei nebeneinander verlegten Eindeckelementen 1 ist zwischen diesen ein Spalt 2 ausgebildet Die feuchtigkeitsdichte Überbrükkung dieses Spaltes 2 geschieht mit den Kunststoffmulden 3 aus formstabilen Kunststoffolien, deren aufrecht stehende Wangen 4 und 5 übereinandergreifen. Die Wangen 4 und 5 legen sich d^bei in dem Spalt 2 dicht aneinander. Durch den auf diese Weise geschlossenen Spalt 2 kann keine Feuchtigkeit mehr in den Dachraum eintreten und Dachlatten sowie Sparren durch Verrotten gefährden. Zwischen das Eindeckelement 1 und die Kunststoffmulde 3 eindringendes Wasser fließt auf dem Boden 6 der Kunststoffmulde 3 in Richtung des eingezeichneten Pfeiles ab, und zwar bis zur Traufe, da sich die Kunststoffmulden 3 einsprechend Fig.3 überlappen. provided sectional drawing of two cover elements 1 laid side by side is a between these Gap 2 formed The moisture-tight bridging of this gap 2 is done with the plastic troughs 3 made of dimensionally stable plastic films, the upright cheeks 4 and 5 of which overlap. the Cheeks 4 and 5 lie close to one another in gap 2. By the closed in this way Gap 2 can no longer penetrate moisture into the roof space and roof battens and rafters from rotting endanger. Between the cover element 1 and the plastic trough 3 penetrating water flows on the Bottom 6 of the plastic trough 3 in the direction of the arrow, up to the eaves, there the plastic troughs 3 overlap in accordance with FIG.

Um eine (vor allem bei Dächern mit geringer Neigung) unter Umständen gefährliche Luftströmung in Richtung von der Traufe zum First zu vermeiden, wird ein aufrecht stehender Steg 7 an den firstseitigen Rand der Kunststoffmulden 3 angeformt.To avoid a potentially dangerous air flow in To avoid the direction from the eaves to the ridge, an upright web 7 is placed on the ridge-side edge the plastic troughs 3 are formed.

Die aufrecht stehenden, in den Spalt 2 hineinragenden Wangen 4 und 5 sind nur sehr dünn und sinr"- also im verlegten Dach kaum bemerkbar. Andererseits ist es möglich, mit den oberen Kanten dieser Wangen 4 und 5 ästhetisch interessante Wirkungen zu erzielen, wenn man sie etwas weiter über die Dachfläche überstehen läßt.The upright ones protruding into the gap 2 Cheeks 4 and 5 are only very thin and sinister "- so im installed roof barely noticeable. On the other hand, it is possible with the upper edges of these cheeks 4 and 5 to achieve aesthetically interesting effects if they protrude a little further over the roof surface leaves.

Die Vorteile einer Dacheindeckung gemäß der Erfindung erschöpfen sich aber nicht in der Schaffung einer 3u gegen Regen und Schnee (auch bei sehr flacher Dachneigung) wirksamen Dichtung. Die Erfindung bringt neue Möglichkeiten der Dacheindeckung. Man kann nämlich jetzt einfache, billige, kurze Bretter, sogar aus Weichholz, unter Umständen Bretterabfall etwa in der Größe von 10 cm bis 50 cm Länge, zum Eindecken verwenden, die nach bekannten Verfahren imprägniert sind. Das Eindeckmaterial ist also bei hoher Lebensdauer sehr billig.The advantages of a roof covering according to the invention are not limited to the creation of a 3u Seal effective against rain and snow (even with very flat roof slopes). The invention brings new roofing options. You can now even make simple, cheap, short boards Use softwood, possibly board scrap approximately 10 cm to 50 cm in length, for covering, which are impregnated by known methods. The covering material has a long service life very cheap.

Man kann die Eindeckelemente 1, vor allem wenn sie aus Holz best ;hen, verschieden einfärben und man kann Eindeckelemente 1 verschiedener Länge oder Breite verwenden (F i g. 4).You can color the cover elements 1, especially if they are made of wood, different colors and you can Use cover elements 1 of different lengths or widths (FIG. 4).

Die Eindeckelemente 1 können beliebig gegeneinander versetzt sein und auch bezüglich ihrer Breite und Dicke verschieden sein (F i g. 4 und 5).The cover elements 1 can be offset from one another as desired and also with regard to their width and Thickness may be different (Figs. 4 and 5).

Die Verlegung der Eindeckelement·: 1 kann auch mit schräg verlaufender Stoßfuge erfolgen (Fig. 6).The covering element ·: 1 can also be laid with an inclined butt joint (Fig. 6).

Es ist also eine Vielzahl von Varianten möglich, um die Eindeckung den verschiedenartigen ästhetischen Forderungen anzupassen.So there is a multitude of variants possible in order to give the roof a different aesthetic appearance To adjust demands.

Ein weiterer wertvoller Vorteil der neuen Dacheindeckung liegt darin, daß man sie mit einer Wärmedämmung verbinden kann, wie Fig. 7 zeigt. In die Kunststoffmulde 3 wird zunächst eine Wärmedämmplatte 8, etwa aus hartgeschäumten Kunststoff, eingelegt und auf diese dann das Eindeckelement 1, etwa eine Holzplatte, aufgelegt. Man erhält auf diese Weise ein feuchtigskeits- und wärmegedämmtes Dach. Wichtig für die neue Eindeckung ist die Wasserabführung von dem Boden 6 der Kunststoffmulde 3. Es ist daher zweckmäßig, für größere Abflußquerschnitte zwischen der Künststoffmulde 3 und dem Eindeckelement 1 zu sorgen.Another valuable advantage of the new roofing is that it can be thermally insulated can connect, as Fig. 7 shows. In the plastic trough 3 is first a thermal insulation board 8, for example made of hard foamed plastic, inserted and then the cover element 1, for example a wooden panel, hung up. In this way, a moisture and heat insulated roof is obtained. Important for the new roof is the water drainage from the bottom 6 of the plastic trough 3. It is therefore useful for larger To provide drainage cross-sections between the plastic trough 3 and the cover element 1.

In den F i g. 8 und 9 geschieht das durch Abstufungen 9 (Fig. 8) oder durch Abschrägungen 10 (Fig. 9) der Ränder der Eindeckelemente 1.In the F i g. 8 and 9 this is done through gradations 9 (Fig. 8) or by bevels 10 (Fig. 9) of the Edges of the flashing elements 1.

Eine andere Möglichkeit zeigt die Fig. 10. Hier sind in den Boden 6 der Kunustoffmulden 3 Wasserabführungskanäle 11 eingeformt. Die gleiche Wirkung läßt sich erreichen, wenn man auf dem Boden 6 Leisten oder Hocker vorsieht.Another possibility is shown in Fig. 10. Here are in the bottom 6 of the Kunustoffmulden 3 water drainage channels 11 molded. The same effect can be achieved if you have 6 strips or on the floor Provides stool.

In den bisherigen Ausführungen war immer nur die Rede von einzelnen Kunststoffmulden 3 wobei jeweils eine Kunststoffmulde 3 einem einzelnen plattenförmigen Eindeckelement 1 zugeordnet war. Es ist das aber nicht die einzige Möglichkeit der Wettersicherung eines solchen Daches. Man kann auch eine Reihe von Kunststoffmulden zu einem sich parallel zur Firstrichtung erstreckenden Streifen zusammenfassen, einem Streifen, der entweder über die ganze Dachlänge läuft oder Teilstreifen aus einer Mehrzahl von Kunststoffmulden, die dann aneinandergefügt werden. An der Stoßstelle zweier solcher Streifen ist dann jeweils wie bei den einzelnen Kunststoffmulden 3 eine Dichtung zu schaffen.In the previous explanations, there was only ever talk of individual plastic troughs 3, in each case a plastic trough 3 was assigned to a single plate-shaped cover element 1. But it is not the only way to weatherproof such a roof. One can also use a number of plastic troughs combine to form a strip that extends parallel to the direction of the ridge, a strip, which runs either over the entire length of the roof or partial strips of a plurality of plastic troughs that then be joined together. At the junction of two such strips is the same as for the individual ones Plastic trays 3 to create a seal.

Solche Streifen lassen sich aus verschieden großen Kunststoffolien formen, aus schmäleren und breiteren, längeren oder kürzeren, so daß man wie im Falle der Einzelkunststoffmulde jedes gewünschte Verlegungsbild der Eindeckelemente herstellen k,".nn. Such strips can be formed from plastic films of different sizes, from narrower and wider ones, longer or shorter ones, so that, as in the case of the individual plastic trough, any desired layout of the roofing elements can be produced k, ". nn.

4. Roof covering according to ernem of claims 1 to 3, characterized in that

- That in the bottom (6) of the plastic troughs (3) water ducts (11) are formed.

5. Roof covering according to one of claims 1 to 4, characterized in that

- That several adjacent plastic troughs (3) are combined into a strip are.

The invention relates to a roof covering arranged at a lateral distance from one another, from Ridge to eaves overlapping plate-shaped roofing elements, which are based on the shape of the elements adapted water-impermeable foils with laterally raised cheeks rest between the cover elements engage and with the cheeks of the foils of the laterally adjacent cover elements are tightly connected.

Such a roof covering is known from FR-PS 27 992, which plate-shaped roofing elements shows, the top and bottom with a film, for. B. made of aluminum, are laminated. This about the elements Foils protruding on all sides and connected to one another at the edge are attached to the perpendicular to the eaves running element edges to form cheeks perpendicular to the roof surface and folded up by means of inverted U-shaped strips connected to the cheeks of the neighboring elements in question in a watertight manner. In the overlap area running parallel to the eaves, the edges of the ridge-side elements overlap the edges of the eaves-side elements and are glued to them This gluing joint must be carried out carefully, so that in the event of a lack of care there is a risk of leakage, especially in the case of relatively flat ones Roofs

From US-PS 14 47 290 a roof covering is also known in which the ridge to the eaves each other overlapping water-bearing elements are laminated on the underside with a sealing film. This protrudes laterally over each element at least at one edge, so that two adjacent ones overlap Elements is possible Here, however, are formed in the area of the parallel to the eaves Overlapping joint towards the roof space narrow openings, which means that these elements can be laid in flat Roof slopes is not advisable

The invention is based on the object of designing a roof covering of the type in question in such a way that, with particularly simple installation, it ensures reliable water drainage that prevents leaks, even with a slight roof pitch
This object is achieved according to the invention in that each film consists of a dimensionally stable plastic trough which has a bent web on its ridge-side edge

This creates an advantageous roof covering with plate-shaped covering elements, which are made from Shingles or wooden boards can be made, with safe drainage even with flat roof slopes is guaranteed and in the event of a possible water backlog, no moisture over the ridge-side Edge of the covering elements can penetrate into the roof. The use of dimensionally stable plastic films for the troughs prevents the well-known sack formation, in which water can collect. In order to it becomes possible under the plate-shaped cover elements according to a further embodiment of the invention to insert a heat-insulating board, as there is no longer any fear of moisture penetration in this board must become.

Further refinements of the invention are the subject matter of claims 3 to 5.
