Zum seitlichen Aneinanderfügen zweier erfindungsgemäßer Dachdämmplatten wird der Formschlusssteg 8 einer ersten Platte in die Formschlussnut 5 einer zweiten Platte eingeschoben oder es wird umgekehrt die Formschlussnut 5 einer ersten Platte auf den Formschlusssteg 8 einer zweiten Platte aufgeschoben. Durch die verjüngende Ausbildung von Formschlussnut 5 einerseits und von Formschlusssteg 8 andererseits wird eine sehr effektive und haltbare formschlüssige Verbindung bzw. Nut-Feder-Verbindung erhalten. Im verlegten Zustand der beiden Platten greift der sich verjüngende Formschlusssteg 8 formschlüssig in die sich ebenfalls verjüngende Formschlussnut 5 ein. Das ist im Schnitt in Figur 5 dargestellt worden. In Figur 5 ist auch erkennbar, dass im Bereich der Überlappungsabschnitte 4, 7 der beiden dort verbundenen Platten eine vollständig formschlüssige Verbindung zwischen beiden Platten verwirklicht wird. Figur 5 zeigt weiterhin, dass sich die beiden Überlappungsabschnitte 4 und 7 im überlappten Zustand zur Gesamtdicke der Platte addieren.For the lateral joining together of two roof insulation panels according to the invention, the form-fitting web 8 of a first board is inserted into the form-fitting groove 5 of a second board or vice versa the form-fitting groove 5 of a first board is pushed onto the form-fitting web 8 of a second board. Due to the tapered design of form-fitting groove 5 on the one hand and of form-fitting web 8 on the other hand, a very effective and durable positive connection or tongue and groove connection is obtained. In the installed state of the two plates of the tapered form-locking web 8 engages positively in the also tapered form-fitting groove 5 a. That's on average in FIG. 5 been presented. In FIG. 5 It can also be seen that in the region of the overlapping sections 4, 7 of the two plates connected there, a completely positive connection between the two plates is realized. FIG. 5 further shows that the two overlap sections 4 and 7 in the overlapped state add to the total thickness of the plate.

Insbesondere in Figur 3 ist erkennbar, dass nach sehr bevorzugter Ausführungsform der Erfindung und im Ausführungsbeispiel die Formschlussnut 5 an beiden Seitenflanken sich über die Länge der Formschlussnut 5 erstreckende Hinterschnitte 10 aufweist. Fernerhin ist in Figur 3 erkennbar, dass der Formschlusssteg 8 entsprechende Komplementärformschlusselemente 11 aufweist. Im verbundenen Zustand zweier benachbarter Platten fassen die Komplementärformschlusselemente 11 an dem Formschlusssteg 8 der ersten Platte formschlüssig in die Hinterschnitte 10 der Formschlussnut 5 der zweiten Platte ein. Mit den Hinterschnitten 10 bzw. mit den Komplementärformschlusselementen 11 wird eine ganz besonders effektive und feste Nut-Feder-Verbindung verwirklicht. Die Figuren 3, 4 und 5 zeigen, dass vorzugsweise und im Ausführungsbeispiel oberhalb des Formschlusssteges 8 eine Stufe 12 vorgesehen ist. In der Stufe 12 ist nach bevorzugter Ausführungsform und im Ausführungsbeispiel ein Wasserabführungskanal 13 angeordnet.In particular in FIG. 3 It can be seen that according to a very preferred embodiment of the invention and in the exemplary embodiment, the form-locking groove 5 on both side flanks over the length of the form-locking groove 5 extending undercuts 10 has. Furthermore, in FIG. 3 recognizable that the form-fitting web 8 corresponding complementary form-locking elements 11 has. In the connected state of two adjacent plates, the complementary form-locking elements 11 form-fittingly grip the form-fitting web 8 of the first plate in the undercuts 10 of the form-locking groove 5 of the second plate. With the undercuts 10 and with the Komplementärformschlusselementen 11 a very effective and solid tongue and groove connection is realized. The FIGS. 3, 4 and 5 show that preferably and in the embodiment above the form-fitting web 8, a step 12 is provided. In stage 12, a water discharge channel 13 is arranged according to the preferred embodiment and in the embodiment.

Eine vergleichende Betrachtung der Figuren 1 und 2 zeigt, dass die erfindungsgemäße Dachdämmplatte auch an ihrer Firstseite 6 einen firstseitigen Überlappungsabschnitt 14 sowie an ihrer Traufseite 9 einen traufseitigen Überlappungsabschnitt 15 aufweist. Im verlegten Zustand der Platten überfasst der traufseitige Überlappungsabschnitt 15 den firstseitigen Überlappungsabschnitt 14 einer benachbarten Platte.A comparative analysis of the FIGS. 1 and 2 shows that the roof insulation board according to the invention also on its ridge side 6 has a ridge-side overlapping section 14 and on its eaves side 9 a eaves-side overlap section 15.
