Description

Die Erfindung betrifft über Dachsparren verlegbare Wärmedämmplatten, die an ihrem stufenfalzartig ausgebildeten firstseitigen Rand einen in der Eindeckung von der firstseitigen Nachbarplatte überlappten Auflagerstreifen, an ihrem stufenfalzartig ausgebildeten traufseitigen Rand einen den Auflagerstreifen der traufseitigen Nachbarplatte überlappenden Deckstreifen und an ihren seitlichen Rändern einen Seitenfalzteil bzw. einen komplementär dazu ausgebildeten Deckfalzteil zur Bildung einer Seitenverfalzung aufweist und mit in First-Traufrichtung verlaufenden Wasserführungskanälen.The invention relates to thermal insulation boards which can be laid over rafters, which have a step-fold-like ridge-side edge overlapping support strips in the covering of the ridge-side neighboring plate, on their step-fold-like eaves-side edge a cover strip overlapping the support strip of the eave-side neighboring plate and a side fold part or one on their side edges has complementary cover fold part to form a side fold and with water channels running in the ridge direction.

Eine derartige Wärmedämmplatte ist durch die DE-A-2 519 459 bekannt und trägt auf der Oberseite eine Vielzahl von in First-Traufrichtung verlaufenden Wasserführungskanäle, welche für eine Ableitung des auf der Oberfläche des Wärmedämmelementes angesammelten Wassers bewirken soll. Wenn bei einem Satteldach die einzelnen Elemente am Ortgang beginnend in üblicher Weise nebeneinander verlegt werden, ergibt sich, daß die Seitenverfalzung zwischen den einzelnen Elementen vom First zur Traufe verlaufend hintereinander zu liegen kommen. Dadurch ergeben sich in den Kreuzungspunkten der in der Projektion vertikal verlaufenden Seitenverfalzungen und der horizontal verlaufenden Verfalzung Bereiche, die keine sichere Wasserführung gewährleisten, sodaß insbesondere beim Eindringen größerer Wassermengen dieses auch in den Unterdachbereich vordringen kann.Such a thermal insulation board is known from DE-A-2 519 459 and bears on the upper side a plurality of water guiding channels which run in the first eaves direction and which are intended to discharge the water accumulated on the surface of the thermal insulation element. If, in the case of a saddle roof, the individual elements are laid next to one another in the usual way starting at the verge, the result is that the side folds between the individual elements from the ridge to the eaves run one behind the other. This results in areas in the intersection of the vertical side folds in the projection and the horizontal folds that do not ensure reliable water flow, so that in particular when larger amounts of water penetrate, this can also penetrate into the under-roof area.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen zu schaffen, mit welchen eine absolut sichere Wasserführung auch beim Eindringen größerer Wassermassen von der Seitenverfalzung zu den Wasserführungskanälen auf der Oberseite der Wärmedämmplatten gewährleistet ist.The invention has for its object to provide measures with which an absolutely safe water flow is guaranteed even when larger amounts of water penetrate from the side interlocking to the water guide channels on the top of the thermal insulation panels.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die seitlichen Ränder der Wärmedämmplatten mit ihren Seiten- und Deckfalzteilen schräg zur senkrechten First-Traufrichtung verlaufen.This object is achieved in that the lateral edges of the thermal insulation boards with their side and top fold parts run obliquely to the vertical ridge direction.

Durch die Maßnahmen der Erfindung wird in vorteilhafter Weise erreicht, daß selbst beim Verlegen der einzelnen Wärmedämmplatten im gleichen Abstand z. B. vom Ortgang die Seitenfalze der firstseitigen Elemente einer Reihe nicht mehr auf die Seitenfalze der dazu traufseitig verlegten Elemente stoßen, sondern vielmehr gegen diese versetzt sind. Dadurch ergibt sich eine bessere Wasserführung, da der Wasserlauf von einer Plattenreihe zur traufseitig darunter angeordneten Plattenreihe seitlich zur Plattenmitte hin versetzt wird und über die in First-Traufrichtung verlaufenden Wasserführungskanäle weiter abgeleitet werden kann. Durch die schräg zur First-Traufrichtung verlaufenden seitlichen Ränder der Wärmedämmplatte ergibt sich ein weiterer Vorteil derart, daß die von den Wärmedämmelementen abgetragene Ziegellast im Bereich des Seitenfalzes eine Horizontalkomponente hat, die eine Tendenz hat, das Element so zu verschieben, daß sich die Fuge im Bereich der Seitenfalze zu schließen sucht, wodurch dem Eindringen größerer Wassermassen in den Seitenfalz ebenfalls entgegengewirkt wird.The measures of the invention advantageously achieve that even when laying the individual thermal insulation boards at the same distance z. B. from the verge the side folds of the ridge-side elements of a row no longer encounter the side folds of the elements installed on the eaves side, but rather are offset against them. This results in a better water flow, since the watercourse is displaced laterally from the row of plates to the row of plates below on the eaves side and towards the middle of the plate and can be further drained off via the water channels in the ridge direction. Due to the lateral edges of the thermal insulation board, which run obliquely to the ridge eaves direction, there is a further advantage such that the brick load removed from the thermal insulation elements has a horizontal component in the area of the side fold, which has a tendency to shift the element so that the joint in Seek to close the area of the side folds, which also counteracts the penetration of larger water masses into the side fold.

Eine weitere Ausgestaltung der Erfindung sieht vor, daß der am firstseitigen Plattenrand ausgebildete Auflagerstreifen mit einer quer zur Dachneigung angeordneten Rinne versehen ist, deren tiefster Punkt in einen in der Dachneigung ausgerichteten Wasserführungskanal mündet, welcher zur Oberseite des traufseitigen Dachstreifens verläuft.A further embodiment of the invention provides that the support strip formed on the ridge-side panel edge is provided with a groove arranged transversely to the roof pitch, the lowest point of which opens into a water-guiding channel aligned in the roof pitch, which runs to the top of the eave-side roof strip.

Diese an sich bekannte Ausgestaltung der querverlaufenden Rinne wirkt sich weiter dahin aus, daß der traufseitig nächstfolgende Seitenfalz durch die Verschiebung des Wasserlaufes zur Dämmplattenmitte hin weiter entlastet wird, da eventuell eingedrungenes Wasser zum tiefsten Punkt im Mittelbereich der Wärmedämmplatte quer verlaufenden Rinne des senkrechten Wasserführungskanal abläuft und damit vom nächstfolgenden Seitenfalz ferngehalten wird.This known configuration of the transverse gutter has the further effect that the side rebate next to the eaves side is further relieved by the displacement of the watercourse towards the middle of the insulation panel, since any water that has penetrated runs to the lowest point in the central region of the thermal insulation panel and the transverse gutter of the vertical water duct runs and so that it is kept away from the next side fold.

Eine weitere Verbesserung der Wasserführung ergibt sich dadurch, daß die Seitenverfalzung von einer in oder unter der Oberseite des firstseitigen Auflagerstreifens liegenden Ebene traufseitig bis zu einer Ebene ansteigt, die höher als die Unterseite des Deckstreifens liegt. Damit wird selbst bei sehr schmalen, horizontal verlaufenden Auflagerstreifen und Deckstreifen eine sichere Wasserführung zur Oberseite der Wärmedämmung gewährleistet.A further improvement in the water flow results from the fact that the side folds rise from a level in or below the top of the ridge-side support strip to a level that is higher than the underside of the cover strip. This ensures safe water flow to the top of the thermal insulation, even with very narrow, horizontal support strips and cover strips.

Die Vorteile und Merkmale der Erfindung ergeben sich auch aus der nachfolgenden Beschreibung eines Ausführungsbeispieles in Verbindung mit den Ansprüchen und der Zeichnung. Es zeigen:

  • Fig. 2 einen Kreuzungsbereich von vier Wärmdedämmplatten mit einer schräg nach oben verlaufenden Wasserführung;
  • Fig. 3 eine Draufsicht auf zwei seitlich auseinandergezogene Wärmedämmplatten;
  • Fig. 4 einen Schnitt längs der Linie IV-IV der Fig. 1;
  • Fig. 5 einen Schnitt längs der Linie V-V der Fig. 1.
The advantages and features of the invention also result from the following description of an exemplary embodiment in conjunction with the claims and the drawing. Show it:
  • Figure 1 is a plan view of four thermal insulation boards according to the invention.
  • 2 shows a crossover area of four thermal insulation boards with an obliquely upward water supply;
  • Figure 3 is a plan view of two thermal insulation panels laterally pulled apart.
  • Fig. 4 is a section along the line IV-IV of Fig. 1;
  • 5 shows a section along the line VV of FIG. 1st

In Fig. 1 sind vier Wärmedämmplatten 10 dargestellt, welche in einer paarweisen Verlegung übereinander angeordnet sind. Die seitlichen Ränder 11 der einzelnen Wärmedämmplatten sind schräg zur Vertikalen verlaufend ausgebildet, so daß nach dem Verlegen der Platten eine entsprechend schräg verlaufende seitliche Fuge entsteht. Die einzelnen Wärmedämmplatten haben an ihrem firstseitigen Rand einen in der Eindeckung von der firstseitigen Nachbarplatte überlappenden Auflagerstreifen 12, über welchen ein an dem jeweiligen traufseitigen Rand angebrachter Deckstreifen 13 übergreift. Der schräg verlaufende seitliche Rand bewirkt, daß bei dem üblichen Verlegen der einzelnen Wärmedämmplatten übereinander die Stoßfuge am seitlichen Rand nicht unmittelbar ineinander übergeht, sondern gegenüber der nächsten Verlegereihe versetzt ist. Wenn mit den Wärmedämmplatten z. B. ein Sattendach belegt wird, kann das an den Ortgang anstoßende Element längs den Rillen 15 in der Oberfläche beschnitten werden, damit die Elemente mit der senkrecht verlaufenden Stirnseite am Ortgang anliegen. Aus der Darstellung gemäß Fig. 1 ist klar erkennbar, daß in einem solchen Fall die seitlichen Fugen der übereinander verlegten Dämmplatten immer gegeneinander versetzt sind.In Fig. 1, four thermal insulation panels 10 are shown, which are arranged one above the other in pairs. The lateral edges 11 of the individual thermal insulation boards are designed to run obliquely to the vertical, so that after laying the boards a correspondingly slanted lateral joint is created. The individual thermal insulation panels have on their ridge-side edge a support strip 12 which overlaps in the covering of the ridge-side neighboring panel and over which a cover strip 13 attached to the respective eaves-side edge overlaps. The sloping side edge has the effect that when the individual thermal insulation boards are laid one above the other, the butt joint does not merge directly into one another at the side edge, but is offset with respect to the next laying row. If with the thermal insulation boards z. B. a satellite roof is occupied, the element adjacent to the verge can be trimmed along the grooves 15 in the surface, so that the elements rest with the vertically extending end face at the verge. 1 that in such a case the lateral joints of the insulation boards laid one above the other are always offset from one another.

Zur Wasserführung sind die einzelnen Wärmedämmplatten 10 auf der Oberseite mit einem Wasserführungskanal 17 versehen, der aus einer Ebene unterhalb der Oberfläche des Auflagerstreifens 12 in eine Ebene oberhalb der Unterfläche des Deckstreifens 13 verläuft. In diesen Wasserführungskanal 17 mündet eine längs der traufseitigen Kante des Auflagerstreifens 12 verlaufende Sammelrinne 18, die vom seitlichen Rand des Elementes in Richtung auf den Wasserführungskanal tiefer wird und im Übergangsbereich zum Wasserführungskanal 17 ihren tiefsten Punkt hat. Eine entsprechende Sammelrinne 19 ist an der traufseitigen Kante der im unteren Drittel der Wärmedämmplatte 10 quer zur Platte verlaufenden Nut 20 vorgesehen, die ebenfalls mit ihrem tiefsten Punkt in den Wasserführungskanal 17 mündet. Diese Nut 20 dient zum Einlegen der Ziegelnasen beim Verlegen der wasserführenden Dachplatten.To guide the water, the individual thermal insulation panels 10 are provided on the upper side with a water guide channel 17, which runs from a level below the surface of the support strip 12 to a level above the lower surface of the cover strip 13. In this water guide channel 17 a collecting channel 18 runs along the eaves-side edge of the support strip 12, which becomes deeper from the side edge of the element in the direction of the water guide channel and has its lowest point in the transition area to the water guide channel 17. A corresponding collecting channel 19 is provided on the eaves-side edge of the groove 20 which runs transversely to the plate in the lower third of the thermal insulation board 10 and likewise opens at its lowest point into the water guide channel 17. This groove 20 is used to insert the tile lugs when laying the water-bearing roof panels.

Die Lage der Sammelrinnen 18 und 19 sowie des Wasserführungskanals 17 geht auch aus Fig. 5 hervor. Die Sammelrinnen 18 und 19 verlaufen von ihrem dargestellten tiefsten Punkt aus in Richtung zum seitlichen Rand der Wärmedämmplatten, praktisch bis in die Ebene der Oberfläche des Auflagerstreifens 12 bzw. der Basisfläche der Nut 20.The position of the collecting troughs 18 and 19 and the water guide channel 17 can also be seen in FIG. 5. The collecting channels 18 and 19 run from their deepest point shown in the direction of the lateral edge of the thermal insulation boards, practically up to the level of the surface of the support strip 12 or the base surface of the groove 20.

Durch diese Ausbildung der Sammelrinnen 18, 19 und des Wasserführungskanales 17 wird eine sichere Wasserführung gewährleistet, so daß der Wasserlaufweg im seitlichen Falz durch die Schrägführung des seitlichen Falzes nicht in einen weiteren Falz ummittelbar übergeht, sondern durch die Versetzung im Bereich einer Sammelrinne endet, von der aus das Wasser zum Wasserführungskanal sicher abgeleitet wird. Damit wird gewährleistet, daß selbst beim Eindringen größerer Wassermengen der Wasserverlauf vom seitlichen Falz zur Mitte der nächstfolgenden Wärmedämmplatte hin verschoben wird und sich somit keine allmähliche Vergrößerung der Wassermenge im seitlichen Falzbereich ergeben kann, was eine Überflutung der Wasserführungsrinne 23 im seitlichen Falz gemäß Fig. 4 mit sich bringen kann. Diese Gefahr ist bei herkömmlichen Elementen gegeben, wenn insbesondere bei einem Satteldach die ersten Elemente der jeweils übernächsten Reihe nicht beschnitten werden, so daß sich eine versetzte Anordnung der senkrecht verlaufenden Stoßfugen ergibt.This design of the collecting troughs 18, 19 and the water guide channel 17 ensures a safe water flow, so that the water flow path in the lateral fold does not immediately pass into another fold due to the inclined guidance of the lateral fold, but ends by the displacement in the area of a collecting trough which is safely drained from the water to the water channel. This ensures that even when larger amounts of water penetrate, the water flow is shifted from the side rebate to the center of the next thermal insulation panel and thus there is no gradual increase in the amount of water in the side rebate area, which floods the water guide channel 23 in the side rebate according to FIG. 4 can bring with it. This risk exists with conventional elements if, in particular in the case of a saddle roof, the first elements of the row after the next are not trimmed, so that there is an offset arrangement of the vertical butt joints.

Mit den Wärmedämmplatten gemäß der Erfindung können auch herkömmliche Wärmedämmplatten mit senkrecht verlaufenden seitlichen Stoßfugen zusammen verlegt werden, wobei sich dann die Situation ergibt, daß zwangsläufig eine Versetzung der seitlichen Stoßfugen gegeben ist, wenn die jeweils übernächste Reihe von Elementen mit herkömmlichen Elementen verlegt wird. In diesem Fall wird in der einen Elementenreihe das Wasser über die schräg verlaufende Seitenfuge und in der anderen Elementenreihe über die senkrecht verlaufende Seitenfuge weitergeführt und gelangt jeweils in die auf der Traufseite angeordnete Sammelrinne 18 des traufseitigen Elementes.With the thermal insulation boards according to the invention, conventional thermal insulation boards with vertical lateral butt joints can also be laid together, which then results in the situation that the lateral butt joints are inevitably displaced when the next but one row of elements is laid with conventional elements. In this case, in one row of elements, the water is carried over the oblique side joint and in the other row of elements over the perpendicular side joint and in each case reaches the collecting channel 18 of the element on the eaves side.

In Fig. 1 ist der Kreuzungspunkt von vier Elementen dargestellt, bei welchen die seitliche Wasserführungsnuten 22 und 23 gemäß Fig. 4 von einer Ebene am firstseitigen Plattenrand in einer in oder unter der Oberseite des Auflagerstreifens 12 liegenden Ebene schräg nach oben in eine am traufseitigen Rand liegende Ebene ansteigt, die höher liegt als die Unterseite des Deckstreifens 13. Man erkennt aus der Darstellung, daß bei einer nur geringfügigen Versetzung der seitlichen Fuge von einer Elementenreihe zur anderen Elementenreihe die über die seitlichen Sammelrinnen 23 abfließenden Wassermassen in die quer verlaufende Sammelrinnen 18 gelangen und zum Wasserführungskanal abgeleitet werden.In Fig. 1, the crossing point of four elements is shown, in which the lateral water guide grooves 22 and 23 according to FIG. 4 from a plane on the ridge-side plate edge in a plane lying in or under the top of the support strip 12 obliquely upwards into a on the eaves-side edge lying level rises, which is higher than the underside of the cover strip 13. It can be seen from the illustration that with only a slight displacement of the lateral joint from one row of elements to another row of elements, the water masses flowing off through the lateral collecting channels 23 reach the transverse collecting channels 18 and be derived to the water channel.

In Fig. 3 sind in einer Draufsicht die seitlichen Randbereiche zweier benachbarter Wärmedämmplatten 10 in auseinandergezogener Darstellung gezeigt, um einen weiteren Vorteil der Erfindung zu erläutern, der sich durch die Schrägführung des Seitenfalzes zusätzlich ergibt. Beim Verlegen der einzelnen Wärmedämmplatten stützen diese sich gegenseitig aneinander ab. Wenn nach dem Verlegen die Dachplatten aufgelegt werden, ergibt sich durch die Dachlast eine nach unten gerichtete Kraftkomponente L1, die im Bereich des Seitenfalzes eine Zerlegung in eine Längskomponente L2 und in eine horizontale Komponente L3 erfährt. Diese horizontale Komponente L3 wirkt sich günstig aus, indem nämlich im Falz ein Schießdruck entsteht, der durch die Dachplattenlast die Fuge zwischen zwei benachbarten Elementen zu verkleinern sucht, wenn sich die üblichen Verschiebungen und Anpassungen nach dem Verlegen des Daches ergeben. Diese Horizontalkomponente L3 und die damit gegebene Tendenz, den seitlichen Fugenabstand zu verkleinern, hat den Vorteil, daß die Fuge nur sehr wenig Wasser aufnehmen kann und damit auch die Gefahr weiter verringert wird, daß die Sammelrinne 23 im Bereich des Seitenfalzes überläuft.In Fig. 3, the side edge regions of two adjacent thermal insulation panels 10 are shown in an exploded view in a plan view to explain a further advantage of the invention, which additionally results from the inclined guide of the side fold. When laying the individual thermal insulation boards, they support each other. If the roof panels are laid after laying, the roof load results in a downward force component L1, which in the area of the side fold is broken down into a longitudinal component L2 and a horizontal component L3. This horizontal component L3 has a favorable effect, namely because there is a shooting pressure in the rebate, which tries to reduce the gap between two adjacent elements due to the roof panel load if the usual displacements and adjustments result after the roof has been installed. This horizontal component L3 and the resulting tendency to reduce the lateral joint spacing has the advantage that the joint can absorb only very little water and thus the risk that the collecting channel 23 overflows in the region of the side fold is further reduced.

Durch die Maßnahmen der Erfindung mit dem schräg zur senkrechten First-Traufrichtung verlaufenden Seitenfalz und in Kombination mit den Sammelrinnen und den Wasserführungskanälen sowie der von der Unterseite des Auflagerstreifens zur Oberseite des Deckstreifens verlaufenden Seitenverfalzung ergibt sich eine in jeder Hinsicht sichere Wasserführung, bei der von Element zu Element das Wasser immer zur Oberfläche geführt wird und ein Durchdringen von Wasser selbst im Überkreuzungspunkt von Elementen sicher ausgeschlossen ist. Damit ergibt sich eine sehr hohe Sicherheit gegen eindringendes Wasser, selbst wenn beim Verlegen der einzelnen Wärmedämmplatten eine versetzte Seitenfalzführung nicht sorgfältig eingehalten wird oder eingehalten werden kann.The measures of the invention with the side fold running obliquely to the vertical ridge direction and in combination with the collecting troughs and the water guiding channels as well as the side folds running from the underside of the support strip to the top of the cover strip result in a safe water flow in all respects, by Element for element the water is always led to the surface and penetration of water even at the crossover point of elements is definitely excluded. This results in a very high level of security against ingress of water, even if an offset side rebate guide is not or cannot be carefully observed when laying the individual thermal insulation boards.
