Definitions
- the invention relates to a sub-roof for roofs covered with roofing panels according to the preamble of claim 1.
- a known, generic sub-roof for roofs covered with roofing panels (DE 36 23 428 C2) consists of overlapping in the downward direction, on the top with at least one hanging edge for the roofing panels, laid on roof battens. These each have a central part, which is followed by a wedge-shaped plate part on the first and eaves side, which in each case merges into the plate middle part via a step and corresponds to the other wedge-shaped plate part with respect to its length measured in the direction of the slope.
- the sum of the lengths of the middle and the eaves-side panel part, measured in the slope direction, corresponds at least to the length of the ridge-side panel part, the length of which corresponds approximately to the distance between the roof battens.
- the invention has for its object to form the thermal insulation panels of a sub-roof of the type in question so that they provide simple coverage with simple and less susceptible to damage training.
- the plate central part has a greater thickness than the edges of the wedge-shaped plate parts facing the plate center.
- the ridge-side panel part passes through an upper-side step and the eaves-side panel part through a lower-side step, which is supported on the ridge-side side surface of the roof batten in question, into the central panel part.
- the side panel edges form a side fold, which begins at a distance from the ridge-side panel edge in the ridge-side panel part, extends over the central panel part and ends at a distance from the eaves-side panel edge in the eaves-side panel part and which rises at an acute angle to the roof battens level.
- the thermal insulation boards used in the sub-roof according to the invention advantageously have a compact shape and a handy size. They result in a single covering in the covering. When pulling in the downward direction, no significant weak points are formed due to the wedge-shaped overlap, so that a uniform thermal insulation panel size is suitable for different distances between the roof battens.
- the thermal insulation boards are pulled in the downward direction, the mutual positions and relative heights of each other adjust so that the contact surfaces lie essentially flat against one another. The contact surfaces are also pressed together by the weight of the roofing slabs, so that very high windproofness is achieved with largely gap-free thermal insulation.
- the side folds do not need to be installed flush in the direction of the slope are, so that with a shifted plate laying in the individual rows according to claim 7, a great tightness, in particular also a high windproofness, is obtained.
- a thermal insulation panel 1 for creating a sub-roof which consists of a wedge-shaped, ridge-side panel part 2, a central panel part 8 and a wedge-shaped, eaves-side panel part 3, the wedge-shaped panel parts 2, 3 thicker towards the center of the panel and pass into the middle part of the plate 8 via a step 6 on the lower side or a step 20 on the upper side.
- the wedge-shaped plate parts 2, 3 correspond to one another in their length measured in the downward direction.
- the underside 4 of the eaves-side plate part 3 and the top 5 of the first-side plate part 2 form flat contact surfaces in the covering (cf. FIG. 4).
- the step 6 on the underside is supported on the ridge-side side surface 11 of a roof batten 12 (cf. FIG. 4).
- a support strip 7 is provided on the ridge-side edge 9 of the ridge-side plate part 2, the width of which corresponds approximately to the width of the roof batten 12 underneath.
- the underside 13 of the support strip 7 merges with the roof batten 12 into the underside 15 of the ridge-side panel part 2, which is below the top of the batten and above the rafter top, and which is flush with the underside of the panel middle part 8.
- An arched transition 14 is provided here, which looks good from the inside of the roof.
- the roof battens level 10 is indicated by a dashed line (cf. also Fig. 4).
- the underside 4 of the eaves-side plate part 3 starts from the base of the underside step 6 as a flat surface and is inclined at an acute angle upwards with respect to the roof battens plane 10. Accordingly, the top 5 of the ridge-side plate part 2 starts from the base of the top step 20 as a flat surface and runs parallel to the bottom 4.
- the side fold 25 is designed as a step fold with a water guide channel 21 in the covered fold part 23, which is overlapped by a cover fold part 22 on the other longitudinal edge of the adjacent thermal insulation panel 1.
- the covered fold part 23 ends to form a downwardly open outlet 24 at a distance in front of the eaves-side end of the side fold 25.
- the side fold 25 begins at a distance from the ridge-side plate edge 9 in the ridge-side plate part 2, extends over the plate middle part 8 and ends at a distance from the eaves-side Panel edge 19 in the eaves-side panel part 3.
- the side rebate 25 rises at an acute angle to the roof battens level 10.
- the dashed lines 26 in FIG. 2 indicate thermal insulation panels 1 covering the ridge side, from which it can be seen that these are offset from one another in the individual rows.
- thermal insulation boards 1 show a side view of a plurality of thermal insulation boards 1 laid on a roof structure. These are shown in their densest crowded position, the eaves and ridge-side plate parts 3 and 2 overlapping with their undersides 4 and tops 5 tapering outward and obliquely. It is readily apparent that with slightly sloping roof battens 12, the individual thermal insulation panels 1 with their sloping undersides 4 and tops 5 can be pulled apart in a sliding manner. The thermal insulation panels 1 pivot around the tops of the roof battens 12 and the steps 6 move a little further down next to the ridge-side surfaces 11 of the roof battens 12, for which purpose the distance 27 between the panel undersides 15 and the rafters 28 is required. Despite this pulling apart, the thermal insulation boards 1 adjust relative to each other again so that the undersides 4 and the tops 5 lie on one another essentially without gaps.
- the sub-roof constructed according to FIG. 4 is covered with roof covering plates 29 formed from beaver tail roof plates, which are suspended from the hanging strips 17 and 18.
- the weight of the roofing panels 29 presses the undersides 4 and the tops 5 close together.
- FIG. 5 shows a somewhat modified, second embodiment of thermal insulation boards 1, in which the strips 17, 18 are made wider than in the first embodiment, again with a step 20 as a hooking edge and a groove 30 for hooking in a further roofing board 29 is.
- a third embodiment of thermal insulation boards 1 (cf. FIG. 6) is only modified compared to the second embodiment in that the hanging edge is formed by a further step 20 which is offset somewhat on the eaves side. This enables a very short plate design to be achieved, but the undersides 4 and the top sides 5 must be chosen to be relatively large.
- FIG. 7 A fourth embodiment is shown in FIG. 7.
- the side fold 25, as shown in FIG. 8, is designed as a water-guiding tongue 32 engaging in a groove 31. 7 also does not extend to the ridge-side and eaves-side panel edge 9 or 19.
- the thermal insulation panels 1 are point-symmetrical in cross-section, so that they can be used on the left and right and are rotatable. Drainage grooves (not shown) can be formed in the hanging strips 17, 18 in a known manner.

Abstract
Description
Die Erfindung betrifft ein Unterdach für mit Dacheindeckungsplatten eingedeckte Dächer nach dem Oberbegriff des Anspruchs 1.The invention relates to a sub-roof for roofs covered with roofing panels according to the preamble of claim 1.
Ein bekanntes, gattungsgemäßes Unterdach für mit Dacheindeckungsplatten eingedeckte Dächer (DE 36 23 428 C2) besteht aus in Gefällerichtung einander überlappenden, oberseitig mit mindestens einer Einhängekante für die Dacheindeckungsplatten versehenen, auf Dachlatten verlegten Wärmeplatten. Diese weisen jeweils einen Mittelteil auf, an den sich first- und traufseitig je ein keilförmig gegen die Plattenmitte hin dicker werdender Plattenteil anschließt, welcher jeweils über eine Stufe in den Plattenmittelteil übergeht und bezüglich seiner in Gefällerichtung gemessenen Länge dem anderen keilförmigen Plattenteil entspricht.A known, generic sub-roof for roofs covered with roofing panels (DE 36 23 428 C2) consists of overlapping in the downward direction, on the top with at least one hanging edge for the roofing panels, laid on roof battens. These each have a central part, which is followed by a wedge-shaped plate part on the first and eaves side, which in each case merges into the plate middle part via a step and corresponds to the other wedge-shaped plate part with respect to its length measured in the direction of the slope.
Bei den verwendeten Wärmedämmplatten entspricht die Summe der Längen des mittleren und des traufseitigen Plattenteils, in Gefällerichtung gemessen, mindestens der Länge des firstseitigen Plattenteils, dessen Länge etwa dem Dachlattenabstand entspricht. Dies führt zu relativ langen Wärmedämmplatten, die in der Weise zu verlegen sind, daß sie eine versetzte Doppel-oder Mehrfachdeckung bilden. Aufgrund der Doppel- oder Mehrfachdeckung sind keine wasserführenden Seitenverfalzungen erforderlich. Durch die notwendige, relativ große Länge der Wärmedämmplatten kann jedoch die Lagerung, der Transport und die Verlegung im Vergleich zu kürzeren Plattenausführungen, wie sie für Einfachdeckungen verwendet werden, je nach den vorliegenden Gegebenheiten, erschwert sein. Kürzere Plattenausführungen für Einfachdeckungen haben aber meist komplizierte Seitenfalzausbildungen, die anfällig gegen Beschädigungen sind.In the case of the thermal insulation panels used, the sum of the lengths of the middle and the eaves-side panel part, measured in the slope direction, corresponds at least to the length of the ridge-side panel part, the length of which corresponds approximately to the distance between the roof battens. This leads to relatively long thermal insulation boards which have to be laid in such a way that they form an offset double or multiple covering. Due to the double or multiple cover, no water-bearing side folds are required. Due to the necessary, relatively large length of the thermal insulation boards, storage, transport and laying can be difficult compared to shorter board designs, such as are used for single roofing, depending on the circumstances. Shorter panel designs for single covers usually have complicated side rebate designs that are susceptible to damage.
Der Erfindung liegt die Aufgabe zugrunde, die Wärmedämmplatten eines Unterdachs der in Rede stehenden Art so auszubilden, daß sie bei einfacher und gegen Beschädigungen wenig anfälliger Ausbildung eine Einfachdeckung ergeben.The invention has for its object to form the thermal insulation panels of a sub-roof of the type in question so that they provide simple coverage with simple and less susceptible to damage training.
Diese Aufgabe wird mit den Merkmalen im kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved with the features in the characterizing part of claim 1.
Gemäß Anspruch 1 hat der Plattenmittelteil eine größere Dicke als die der Plattenmitte zugekehrten Ränder der keilförmigen Plattenteile. Dabei gehen der firstseitige Plattenteil durch eine oberseitige Stufe und der traufseitige Plattenteil durch eine an der firstseitigen Seitenfläche der betreffenden Dachlatte sich abstützende unterseitige Stufe in den Plattenmittelteil über. Die seitlichen Plattenränder bilden eine Seitenverfalzung, die im Abstand vom firstseitigen Plattenrand im firstseitigen Plattenteil beginnt, sich über den Plattenmittelteil erstreckt und im Abstand vom traufseitigen Plattenrand im traufseitigen Plattenteil endet und die dabei spitzwinklig zur Dachlattenebene ansteigt.According to claim 1, the plate central part has a greater thickness than the edges of the wedge-shaped plate parts facing the plate center. The ridge-side panel part passes through an upper-side step and the eaves-side panel part through a lower-side step, which is supported on the ridge-side side surface of the roof batten in question, into the central panel part. The side panel edges form a side fold, which begins at a distance from the ridge-side panel edge in the ridge-side panel part, extends over the central panel part and ends at a distance from the eaves-side panel edge in the eaves-side panel part and which rises at an acute angle to the roof battens level.
Vorteilhafterweise haben die im erfindungsgemäßen Unterdach verwendeten Wärmedämmplatten eine kompakte Form und eine handliche Größe. Sie ergeben in der Eindeckung eine Einfachdeckung. Beim Ziehen in Gefällerichtung bilden sich aufgrund der keilförmigen Überdeckung keine wesentlichen Schwachstellen, so daß eine einheitliche Wärmedämmplattengröße für unterschiedliche Dachlattenabstände geeignet ist. Bei einem Ziehen der Wärmedämmplatten in Gefällerichtung stellen sich diese in ihrer gegenseitigen Lage und relativen Höhe zueinander wieder so ein, daß die Anlageflächen im wesentlichen plan aneinanderliegen. Die Anlageflächen werden zudem durch das Gewicht der Dacheindeckungsplatten aneinandergepreßt, so daß eine sehr hohe Winddichtheit bei weitgehend spaltfreier Wärmedämmung erzielt wird.The thermal insulation boards used in the sub-roof according to the invention advantageously have a compact shape and a handy size. They result in a single covering in the covering. When pulling in the downward direction, no significant weak points are formed due to the wedge-shaped overlap, so that a uniform thermal insulation panel size is suitable for different distances between the roof battens. When the thermal insulation boards are pulled in the downward direction, the mutual positions and relative heights of each other adjust so that the contact surfaces lie essentially flat against one another. The contact surfaces are also pressed together by the weight of the roofing slabs, so that very high windproofness is achieved with largely gap-free thermal insulation.
Durch die keilförmig verlaufenden Anlageflächen ist eine einfache und robuste Seitenfalzausbildung möglich, die gegen Beschädigungen wenig anfällig ist. Zudem ist eine gute First-und Trauflösung realisierbar.Thanks to the wedge-shaped contact surfaces, simple and robust side fold formation is possible, which is less susceptible to damage. A good ridge and eaves solution can also be implemented.
Mit den Merkmalen nach Anspruch 2 wird erreicht, daß am Beginn der Seitenverfalzung im firstseitigen Plattenteil eine ausreichend große Materialdicke für eine robuste Ausbildung der Seitenverfalzung mit nicht zu geringen Querschnitten zur Verfügung steht.With the features of claim 2 it is achieved that at the beginning of the side fold in the ridge-side panel part a sufficiently large material thickness is available for a robust design of the side fold with not too small cross sections.
Mit den Merkmalen gemäß den Ansprüchen 3, 4 und 5 werden zwei Ausführungsformen von Seitenverfalzungen angegeben, die besonders robust und gegen Beschädigungen wenig anfällig ausgebildet sind.With the features according to
Bei einer im Querschnitt gesehen punktsymmetrischen Ausbildung der Wärmedämmplatten nach Anspruch 6 wird die Verlegearbeit dahingehend vereinfacht, daß nicht zwischen Ober- und Unterseite der Wärmedämmplatten unterschieden werden muß.With a cross-sectionally symmetrical design of the thermal insulation panels according to claim 6, the laying work is simplified to the extent that it is not necessary to differentiate between the top and bottom of the thermal insulation panels.
Aufgrund der Gestalt der Wärmedämmplatten brauchen die Seitenverfalzungen nicht in Gefällerichtung fluchtend verlegt zu werden, so daß bei einer versetzten Plattenverlegung in den einzelnen Reihen gemäß Anspruch 7 eine große Dichtheit, insbesondere auch eine hohe Winddichtheit, erhalten wird.Due to the shape of the thermal insulation panels, the side folds do not need to be installed flush in the direction of the slope are, so that with a shifted plate laying in the individual rows according to

In Fig. 1 ist eine Wärmedämmplatte 1 zur Erstellung eines Unterdachs dargestellt, die aus einem keilförmigen, firstseitigen Plattenteil 2, einem Plattenmittelteil 8 und einem keilförmigen, traufseitigen Plattenteil 3 besteht, wobei die keilförmigen Plattenteile 2, 3 gegen die Plattenmitte hin dicker werden und jeweils über eine unterseitige Stufe 6 bzw. über eine oberseitige Stufe 20 in den Plattenmittelteil 8 übergehen. Die keilförmigen Plattenteile 2, 3 entsprechen einander in ihrer in Gefällerichtung gemessenen Länge.In Fig. 1, a thermal insulation panel 1 for creating a sub-roof is shown, which consists of a wedge-shaped, ridge-side panel part 2, a
Die Unterseite 4 des traufseitigen Plattenteils 3 und die Oberseite 5 des firstseitigen Plattenteils 2 bilden in der Eindeckung plane Anlageflächen (vgl. Fig. 4). Die unterseitige Stufe 6 stützt sich an der firstseitigen Seitenfläche 11 einer Dachlatte 12 ab (vgl. Fig. 4).The
Am firstseitigen Rand 9 des firstseitigen Plattenteils 2 ist ein Auflagerstreifen 7 vorgesehen, dessen Breite etwa der Breite der darunterliegenden Dachlatte 12 entspricht. Die Unterseite 13 des Auflagerstreifens 7 geht neben der Dachlatte 12 in die unter der Dachlattenoberseite und über der Sparrenoberseite liegende Unterseite 15 des firstseitigen Plattenteils 2 über, welche mit der Unterseite des Plattenmittelteils 8 fluchtet. Es ist hier ein bogenförmiger Übergang 14 vorgesehen, der von der Dachinnenseite her gesehen optisch gut aussieht.A
In Fig. 1 ist mit einer strichlierten Linie die Dachlattenebene 10 angedeutet (vgl. auch Fig. 4). Die Unterseite 4 des traufseitigen Plattenteils 3 geht von der Basis der unterseitigen Stufe 6 als plane Fläche aus und ist gegenüber der Dachlattenebene 10 spitzwinklig nach oben geneigt. Entsprechend geht die Oberseite 5 des firstseitigen Plattenteils 2 von der Basis der oberseitigen Stufe 20 als plane Fläche aus und verläuft parallel zu der Unterseite 4.In Fig. 1, the roof battens

Anhand der Fig. 2 und 3 wird die als Seitenverfalzung 25 ausgeführte Längsrandausbildung der Wärmedämmplatte 1 näher erläutert. Die Seitenverfalzung 25 ist als Stufenfalz mit einer Wasserführungsrinne 21 im überdeckten Falzteil 23 ausgebildet, der von einem überdeckenden Falzteil 22 an dem jeweils anderen Längsrand der benachbarten Wärmedämmplatte 1 übergriffen ist. Der überdeckte Falzteil 23 endet zur Bildung eines nach unten offenen Auslaufs 24 im Abstand vor dem traufseitigen Ende der Seitenverfalzung 25. Die Seitenverfalzung 25 beginnt im Abstand vom firstseitigen Plattenrand 9 im firstseitigen Plattenteil 2, erstreckt sich über den Plattenmittelteil 8 und endet im Abstand vom traufseitigen Plattenrand 19 im traufseitigen Plattenteil 3. Dabei steigt die Seitenverfalzung 25 spitzwinkelig zur Dachlattenebene 10 an.2 and 3, the longitudinal edge configuration of the thermal insulation board 1, which is designed as a

In Fig. 4 ist eine Seitenansicht mehrerer auf einer Dachkonstruktion verlegter Wärmedämmplatten 1 dargestellt. Diese sind in ihrer dichtest gedrängten Lage gezeigt, wobei sich die trauf- und firstseitigen Plattenteile 3 bzw. 2 mit ihren Unterseiten 4 und Oberseiten 5 keilförmig und schräg nach außen verlaufend überdecken. Es ist ohne weiteres ersichtlich, daß bei etwas weiter auseinanderliegenden Dachlatten 12 die einzelnen Wärmedämmplatten 1 mit ihren schrägen Unterseiten 4 und Oberseiten 5 aufeinander gleitend auseinandergezogen werden können. Dabei schwenken die Wärmedämmplatten 1 um die Oberseiten der Dachlatten 12 und die Stufen 6 wandern etwas weiter neben den firstseitigen Seitenflächen 11 der Dachlatten 12 nach unten, wozu der Abstand 27 zwischen den Plattenunterseiten 15 und dem Sparren 28 erforderlich ist. Trotz dieses Auseinanderziehens stellen sich die Wärmedämmplatten 1 aber relativ zueinander wieder so ein, daß die Unterseiten 4 und die Oberseiten 5 im wesentlichen ohne Spalte aufeinanderliegen.4 shows a side view of a plurality of thermal insulation boards 1 laid on a roof structure. These are shown in their densest crowded position, the eaves and ridge-side plate parts 3 and 2 overlapping with their
Aus Fig. 4 ist auch deutlich zu erkennen, daß über die Seitenverfalzung 25 eine Weitergabe von Wasser von einer Wärmedämmplatte 1 zur anderen schon bei einer geringen Dachneigung erfolgt, obwohl die Seitenverfalzung 25 nicht bis zum firstseitigen Rand 9 und bis zum traufseitigen Rand 19 reicht.From Fig. 4 it can also be clearly seen that a transfer of water from the thermal insulation board 1 to the other takes place via the
Das nach Fig. 4 aufgebaute Unterdach ist mit aus Biberschwanzdachplatten gebildeten Dacheindeckungsplatten 29 eingedeckt, die an den Einhängeleisten 17 und 18 eingehängt sind. Das Gewicht der Dacheindeckungsplatten 29 preßt dabei die Unterseiten 4 und die Oberseiten 5 dicht aufeinander.The sub-roof constructed according to FIG. 4 is covered with
In Fig. 5 ist eine etwas modifizierte, zweite Ausführungsform von Wärmedämmplatten 1 dargestellt, bei der die Leisten 17, 18 breiter als bei der ersten Ausführungsform ausgeführt sind, wobei wiederum eine Stufe 20 als Einhängekante und eine Rinne 30 zum Einhängen einer weiteren Dacheindeckungsplatte 29 vorhanden ist.5 shows a somewhat modified, second embodiment of thermal insulation boards 1, in which the
Eine dritte Ausführungsform von Wärmedämmplatten 1 (vgl. Fig. 6) ist gegenüber der zweiten Ausführungsform lediglich dadurch modifiziert, daß die Einhängekante durch eine weitere, etwas traufseitig versetzte Stufe 20 gebildet ist. Damit kann eine sehr kurze Plattenausführung erreicht werden, wobei aber die Unterseiten 4 und die Oberseiten 5 relativ groß gewählt werden müssen.A third embodiment of thermal insulation boards 1 (cf. FIG. 6) is only modified compared to the second embodiment in that the hanging edge is formed by a
Eine vierte Ausführungsform ist in Fig. 7 dargestellt. Bei dieser Ausführungsform ist die Seitenverfalzung 25, entsprechend der Darstellung nach Fig. 8, als eine in eine Nut 31 eingreifende, wasserführende Feder 32 ausgeführt. Diese Seitenverfalzung 25 verläuft gemäß Fig. 7 ebenfalls nicht bis zu dem firstseitigen und traufseitigen Plattenrand 9 bzw. 19. Weiter ist aus Fig. 7 zu erkennen, daß die Wärmedämmplatten 1 im Querschnitt gesehen punktsymmetrisch ausgebildet sind, so daß sie links wie rechts verwendbar und drehbar sind. In die Einhängeleisten 17, 18 können in bekannter Weise (nicht eingezeichnete) Entwässerungsrillen eingeformt sein.A fourth embodiment is shown in FIG. 7. In this embodiment, the
