Definitions
- the present invention relates to a thatched roof covering element which consists of a plurality of plastic stalks with a spiral cross-section arranged approximately parallel and one above the other, which are connected to one another in their upper end region.
- a thatched roofing element of the type mentioned in which the stalks are flattened in their upper end region and connected to one another by thermal welding.
- the thermal welding which is expediently carried out with simultaneous pressure on the top and bottom of the upper end regions of the stalks forming the element, creates a permanent connection between the stalk end regions in the simplest way.
- by flattening one largely smooth and flat upper end portion of the element formed which is relatively stable and firm.
- Only the plastic straws are required as material for the element, which means a significant simplification and cheaper manufacture.
- the straws for an element only have to be aligned approximately parallel in a shape, preferably delimited by a rectangle, and locked in this position before welding. Since no base plate is required, the basis weight of the element is relatively low.
- the thatched roof covering element can have an underlying support, which consists of a grid-shaped fabric and is connected to the end regions of the straws or the element by thermal welding, the Carrier extends at least over the area of the thermal welding.
- the tissue of the carrier is at least partially penetrated by the material of the element and is thus intimately connected to it.
- the fact that at least some of the fibers of the carrier's fabric run transversely or diagonally to the longitudinal direction of the straws largely prevents the element from tearing open in the longitudinal direction of the straws.
- the support can also be used for fastening the element to a roof surface if it protrudes beyond the element.
- Hard PVC or impact-resistant hard PVC is useful as the material for the straws, since it combines the required properties - rigidity, weather resistance, formability, colorability and weldability.
- the fact that the stalks are advantageous for the most natural possible visual impression of the element are unevenly long and irregularly shaped at their free ends.
- This shape of the stalks can e.g. B. can be achieved by cutting stalk bundles with a very rough saw.
- the stalks have at least one longitudinally projecting web or wing on their outside. This results in a larger surface area of the straws and increases their resistance to wind kinking.
- the thatched roof covering element according to the invention is advantageously laid in such a way that the element is connected to the roof surface in the welded area by nailing and / or stapling.
- This laying process is simple and quick to carry out and requires neither special knowledge nor special tools. Since the welding area of one element is covered by the stalks of the next element, neither the welding area nor the nailing or stapling is optically disturbing, but the result is a homogeneous arrangement of stalks.
- Another advantage of the thatched roof covering element according to the invention is that it can be adapted to bulges, edges and bends of the roof surface by heating to temperatures in the range of the softening temperature. This ensures tension-free laying of the elements without visually disturbing kinks in the thatched roof area in the area of angled roof areas, dormer windows or the like. This also allows the use of relatively large and rationally manufactured and installed elements.
- the example of the thatched roof covering element 1 shown consists of a plurality of stalks 2, which are arranged approximately parallel next to and above one another in the form of a flat rectangle. In their upper end regions 21, the stalks 2 are flattened and connected to one another by thermal welding. As a result, a largely flat, relatively thin welding area 5 is formed, which is underlaid by a carrier 3.
- This carrier 3 is a lattice-shaped Fabric which is also connected to the upper end region 21 of the straws or of the element by thermal welding. Both welding processes are expediently carried out in one operation.
- the part of the carrier protruding beyond the element 1 can serve for better handling of the element during manufacture and can be used for fastening during laying.
- the stalks 2 are unevenly long, the length of the stalks 2 preferably decreasing from bottom to top.
- the blades 2 are irregularly shaped at their free ends 22.
- Figure 2 finally shows a plastic straw 2 for use in the thatched roofing element according to the invention in cross section.
- the basic shape of the cross section is a spiral that resembles an open six.
- the stem 2 has on its outside 25 approximately radially outwardly projecting webs or wings 4. These webs or wings 4, two are arranged in the example shown, serve to enlarge the surface of the straw 2 and to increase the kink resistance. As a result of this and as a result of the shorter stalk lengths required, the thatched roof covering element 1 and thus a roof covered with it is very insensitive to strong winds.

Abstract
Description
Die vorliegende Erfindung betrifft ein Reet-Dacheindeckungselement, das aus einer Vielzahl von etwa parallel neben- und übereinander angeordneten Kunststoffhalmen mit spiralförmigem Querschnitt besteht, die in ihrem oberen Endbereich miteinander verbunden sind.The present invention relates to a thatched roof covering element which consists of a plurality of plastic stalks with a spiral cross-section arranged approximately parallel and one above the other, which are connected to one another in their upper end region.
Neben Dacheindeckungen aus echtem Reet oder Reed werden zunehmend solche aus mit Kunststoff nachgeahmten Reethalmen erstellt, da letztere sowohl preisgünstiger als auch haltbarer sind.In addition to roof coverings made of real thatch or reed, those made of synthetic straw that are imitated with plastic are increasingly being created, as the latter are both cheaper and more durable.
Aus der DE-PS 33 11 366 ist ein Kunststoffhalm mit einem spiralförmigen Querschnitt bekannt, der für die Dacheindeckung in ähnlicher Weise verwendet wird, wie echtes Reet, d. h. eine Anzahl von Halmen wird durch Bindungen sowohl gebündelt als auch mit der Dachkonstruktion bzw. Dachfläche verbunden. Dieses traditionelle Dacheindeckungsverfahren erfordert einen sehr hohen Arbeitsaufwand und ergibt eine wenig dauerhafte Verbindung der durch die Bündelung gebildeten Reet-Dacheindeckungselemente mit der Dachkonstruktion bzw. -fläche. Wegen der erforderlichen relativ großen Halmlängen kommt es bei starkem Wind zu einem Anheben und Knicken oder Brechen von Halmen, was deren Lebensdauer und damit die der gesamten Dacheindeckung verringert.From DE-PS 33 11 366 a plastic straw with a spiral cross-section is known, which is used for roofing in a similar manner as real thatch, that is, a number of straws are bundled by bonds as well as connected to the roof structure or roof surface . This traditional roofing method requires a very high amount of work and results in a less permanent connection of the thatched roofing elements formed by the bundling with the roof construction or surface. Because of the required relatively long stalk lengths, stalks are raised and kinked or broken in strong winds, which increases their lifespan and thus that of total roof covering reduced.
Um den genannten Nachteilen abzuhelfen, wurden verschiedene Reet-Dacheindeckungselemente entwickelt, denen gemeinsam ist, daß sie eine feste Kunststoff-Grundplatte aufweisen, auf der in unterschiedlicher Weise Kunststoffhalme zur Erzeugung eines Reetdach-Aussehens befestigt sind. Zu nennen sind hier die DE-OS 20 53 642 und die DE-OS 32 24 758, in denen eine stumpfe Verschweißung von Halmen und Grundplatte beschrieben ist, sowie die DE-OS 19 25 494, die in eine auf die Grundplatte gebrachte Schaumschicht eingeschäumte Halmenden beschreibt. Allen derartigen Elementen haftet der Nachteil eines sehr hohen Herstellungs- und Materialaufwandes an, was zu hohen Kosten für eine derartige Dacheindeckung führt.To remedy the disadvantages mentioned, various thatched roofing elements have been developed, which have in common that they have a solid plastic base plate on which plastic straws are attached in different ways to produce a thatched roof appearance. Worth mentioning here are DE-OS 20 53 642 and DE-OS 32 24 758, in which butt welding of stalks and base plate is described, and DE-OS 19 25 494, which is foamed into a foam layer placed on the base plate Halmenden describes. All such elements have the disadvantage of a very high manufacturing and material expenditure, which leads to high costs for such a roof covering.
Es stellt sich daher die Aufgabe, ein Reet-Dacheindeckungselement der eingangs genannten Art zu schaffen, das die genannten Nachteile vermeidet und insbesondere einen geringen Aufwand an Arbeit und Material sowohl bei der Herstellung als auch bei der Verlegung erfordert, das Wasser gut aufnimmt und ableitet und windsicher und lange haltbar ist, das ein geringes Flächengewicht hat und dessen optischer Eindruck dem eines echten Reetdaches weitgehend gleicht.It is therefore the task of creating a thatched roofing element of the type mentioned, which avoids the disadvantages mentioned and in particular requires a small amount of work and material in both the manufacture and laying, the water absorbs and drains well and is windproof and long-lasting, has a low basis weight and its visual impression largely resembles that of a real thatched roof.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß durch ein Reet-Dacheindeckungselement der eingangs genannten Art, bei dem die Halme in ihrem oberen Endbereich abgeflacht und miteinander durch thermische Verschweißung verbunden sind. Durch die thermische Verschweißung, die zweckmäßig bei gleichzeitigem Druck auf die Unter- und Oberseite der oberen Endbereiche der das Element bildenden Halme erfolgt, ist auf einfachste Weise eine dauerhafte Verbindung der Halmendbereiche untereinander geschaffen. Gleichzeitig wird durch die Abflachung ein weitgehend glattflächiger und ebener obener Endbereich des Elementes gebildet, der relativ formstabil und fest ist. Als Material für das Element sind lediglich die Kunststoffhalme erforderlich, was eine wesentliche Vereinfachung und Verbilligung der Fertigung bedeutet. Die Halme für ein Element müssen nur etwa parallel in einer vorzugsweise durch ein Rechteck umgrenzten Form ausgerichtet und in dieser Lage vor dem Verschweißen arretiert werden. Da keine Grundplatte benötigt wird, ist das Flächengewicht des Elementes relativ gering.This object is achieved according to the invention by a thatched roofing element of the type mentioned, in which the stalks are flattened in their upper end region and connected to one another by thermal welding. The thermal welding, which is expediently carried out with simultaneous pressure on the top and bottom of the upper end regions of the stalks forming the element, creates a permanent connection between the stalk end regions in the simplest way. At the same time, by flattening one largely smooth and flat upper end portion of the element formed, which is relatively stable and firm. Only the plastic straws are required as material for the element, which means a significant simplification and cheaper manufacture. The straws for an element only have to be aligned approximately parallel in a shape, preferably delimited by a rectangle, and locked in this position before welding. Since no base plate is required, the basis weight of the element is relatively low.
Zur Stabilisierung der Verbindung der Halme untereinander und zur Vereinfachung der Handhabung bei der Fertigung kann das Reet-Dacheindeckungselement einen unterliegenden Träger aufweisen, der aus einem gitterförmigen Gewebe besteht und mit den Endbereichen der Halme bzw. des Elementes durch thermische Verschweißung verbunden ist, wobei sich der Träger zumindest über den Bereich der thermischen Verschweißung erstreckt. Durch die Verschweißung von Träger und Element bzw. Halmen wird das Gewebe des Trägers wenigstens teilweise vom Material des Elementes durchdrungen und ist so innig mit diesem verbunden. Dadurch, daß mindestens ein Teil der Fasern des Gewebes des Trägers quer oder diagonal zur Längsrichtung der Halme verläuft, wird ein Aufreißen des Elementes in Längsrichtung der Halme weitgehend ausgeschlossen. Der Träger kann außerdem bei Überstand über das Element zusätzlich für die Befestigung des Elementes auf einer Dachfläche herangezogen werden.To stabilize the connection of the straws to each other and to simplify handling during manufacture, the thatched roof covering element can have an underlying support, which consists of a grid-shaped fabric and is connected to the end regions of the straws or the element by thermal welding, the Carrier extends at least over the area of the thermal welding. By welding the carrier and the element or straws, the tissue of the carrier is at least partially penetrated by the material of the element and is thus intimately connected to it. The fact that at least some of the fibers of the carrier's fabric run transversely or diagonally to the longitudinal direction of the straws largely prevents the element from tearing open in the longitudinal direction of the straws. The support can also be used for fastening the element to a roof surface if it protrudes beyond the element.
Als Material für die Halme ist Hart-PVC bzw. schlagfestes Hart-PVC zweckmäßig, da es die erforderlichen Eigenschaften - Steifigkeit, Wetterfestigkeit, Form- und Färbbarkeit und Verschweißbarkeit - in sich vereinigt.Hard PVC or impact-resistant hard PVC is useful as the material for the straws, since it combines the required properties - rigidity, weather resistance, formability, colorability and weldability.
Vorteilhaft für einen möglichst natürlichen optischen Eindruck des Elementes wirkt es sich aus, daß die Halme ungleichmäßig lang und an ihren freien Enden unregelmäßig geformt sind. Diese Form der Halme kann z. B. mittels eines Durchtrennens von Halmbündeln mit einer sehr groben Säge erzielt werden.The fact that the stalks are advantageous for the most natural possible visual impression of the element are unevenly long and irregularly shaped at their free ends. This shape of the stalks can e.g. B. can be achieved by cutting stalk bundles with a very rough saw.
Zur weiteren Annäherung an ein natürliches Aussehen und zur Verbesserung der Wasseraufnahme- und Wasserableitungsfähigkeit ist vorgesehen, daß die Halme auf ihrer Außenseite wenigstens einen längs verlaufenden vorstehenden Steg oder Flügel aufweisen. Dies ergibt eine größere Oberfläche der Halme und erhöht deren Widerstandsfähigkeit gegen Windknickung.To further approximate a natural appearance and to improve the water absorption and water drainage ability, it is provided that the stalks have at least one longitudinally projecting web or wing on their outside. This results in a larger surface area of the straws and increases their resistance to wind kinking.
Schließlich ist zur Erzielung eines möglichst naturgetreuen Aussehens des Reetdaches eine wechselnde Farbtönung innerhalb des Halmes nach Art des natürlichen Reets vorgesehen. Dieser Farbtonwechsel kann relativ einfach durch wechselnde Farbstoffzugaben zur Kunststoffmasse bei der Herstellung des Halmes erzeugt werden und ist damit sehr dauerhaft.Finally, in order to achieve the most natural-looking appearance of the thatched roof, a changing color tone is provided within the straw in the manner of the natural thatch. This color change can be generated relatively easily by changing the amount of dye added to the plastic mass during the production of the straw and is therefore very durable.
Die Verlegung des erfindungsgemäßen Reet-Dacheindeckungselement erfolgt vorteilhaft in der Weise, daß das Element im Verschweißungsbereich mit der Dachfläche durch Nagelung und/oder Klammerung verbunden wird. Dieses Verlegeverfahren ist einfach und schnell durchzuführen und erfordert weder spezielle Kenntnisse noch besondere Werkzeuge. Da der Verschweißungsbereich eines Elementes von den Halmen des nächstfolgenden Elementes überdeckt wird, tritt weder der Verschweißungsbereich noch die Nagelung bzw. Klammerung optisch störend in Erscheinung, sondern es ergibt sich das Bild einer homogenen Anordnung von Halmen.The thatched roof covering element according to the invention is advantageously laid in such a way that the element is connected to the roof surface in the welded area by nailing and / or stapling. This laying process is simple and quick to carry out and requires neither special knowledge nor special tools. Since the welding area of one element is covered by the stalks of the next element, neither the welding area nor the nailing or stapling is optically disturbing, but the result is a homogeneous arrangement of stalks.
Eine größere Sicherheit gegen das Eindringen von Feuchtigkeit in die Dachkonstruktion ergibt sich bei einer Verlegung der Reet-Dacheindeckungselemente unter Zwischenlage einer Bitumenschicht oder bituminösen Schicht. Neben der besseren Dichtigkeit ergibt sich hierbei noch ein stärkerer Halt der Elemente an der Dachfläche durch die Haft- oder Klebewirkung der Bitumenschicht, wenn die Elemente verlegt,werden, bevor diese Schicht erstarrt ist.Greater security against the ingress of moisture into the roof structure is obtained when the thatched roof covering elements are laid under Zwi position of a bitumen layer or bituminous layer. In addition to the better tightness, there is an even stronger hold of the elements on the roof surface due to the adhesive or adhesive effect of the bitumen layer if the elements are laid before this layer has solidified.
Ein weiterer Vorteil des erfindungsgemäßen Reet-Dacheindeckungselementes liegt darin, daß es durch Erwärmung auf Temperaturen im Bereich der Erweichungstemperatur an Wölbungen, Randungen und Biegungen der Dachfläche angepaßt werden kann. Hierdurch ist ein spannungsfreies Verlegen der Elemente ohne optisch störende Knicke in der Reetdachfläche im Bereich von abgewinkelten Dachflächen, Dachgauben o. ä. gewährleistet. Auch erlaubt dies die Verwendung relativ großer und rationell zu fertigender und zu verlegender Elemente.Another advantage of the thatched roof covering element according to the invention is that it can be adapted to bulges, edges and bends of the roof surface by heating to temperatures in the range of the softening temperature. This ensures tension-free laying of the elements without visually disturbing kinks in the thatched roof area in the area of angled roof areas, dormer windows or the like. This also allows the use of relatively large and rationally manufactured and installed elements.
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen im einzelnen:
Figur 1 eine perspektivische Ansicht eines erfindungsgemäßen Reet-Dacheindeckungselementes und- Figur 2 einen Halm des Reet-Dacheindeckungselementes im Querschnitt.
- Figure 1 is a perspective view of a thatched roofing element according to the invention and
- Figure 2 shows a straw of the thatched roofing element in cross section.
Wie Figur 1 zeigt, besteht das dargestellte Beispiel des Reet-Dacheindeckungselementes 1 aus einer Vielzahl von Halmen 2, die etwa parallel neben- und übereinander in Form eines flachen Rechteckes angeordnet sind. In ihren oberen Endbereichen 21 sind die Halme 2 abgeflacht und miteinander durch thermische Verschweißung verbunden. Hierdurch wird ein weitgehend ebener, relativ dünner Verschweißungsbereich 5 gebildet, der von einem Träger 3 unterlegt ist. Dieser Träger 3 ist ein gitterförmiges Gewebe, das ebenfalls durch thermische Verschweißung mit dem oberen Endbereich 21 der Halme bzw. des Elementes verbunden ist. Zweckmäßig erfolgen beide Verschweißungsvorgänge in einem Arbeitsgang. Der über das Element 1 hinausragende Teil des Trägers kann bei der Herstellung zur besseren Handhabung des Elementes dienen und bei der Verlegung zur Befestigung herangezogen werden.As shown in FIG. 1, the example of the thatched
Die Halme 2 sind ungleichmäßig lang, wobei vorzugsweise die Länge der Halme 2 von unten nach oben abnimmt. An ihren freien Enden 22 sind die Halme 2 unregelmäßig geformt.The stalks 2 are unevenly long, the length of the stalks 2 preferably decreasing from bottom to top. The blades 2 are irregularly shaped at their
Figur 2 schließlich zeigt einen Kunststoffhalm 2 für die Verwendung in dem erfindungsgemäßen Reet-Dacheindeckungselement im Querschnitt. Die Grundform des Querschnitts ist eine Spirale, die einer offenen Sechs ähnelt. Zusätzlich weist der Halm 2 an seiner Außenseite 25 etwa radial nach außen vorstehende Stege oder Flügel 4 auf. Diese Stege oder Flügel 4, im dargestellten Beispiel sind zwei angeordnet, dienen zu einer Vergrößerung der Oberfläche des Halmes 2 und zu einer Erhöhung der Knickfestigkeit. Hierdurch und infolge der geringeren erforderlichen Halmlängen ist das Reet-Dacheindeckungselement 1 und damit ein hiermit eingedecktes Dach sehr unempfindlich gegen starken Wind.Figure 2 finally shows a plastic straw 2 for use in the thatched roofing element according to the invention in cross section. The basic shape of the cross section is a spiral that resembles an open six. In addition, the stem 2 has on its outside 25 approximately radially outwardly projecting webs or
