Abstract

The self-supporting roof elements (1) are fully prefabricated at the factory. By virtue of the vertically offset arrangement of the moisture barrier (7) in the region adjacent to the rafters, said moisture barrier between the rafters (3) can rest directly on the heat insulation (4). Any vapour-pressure gradient which may form between the heat-generating region and the ventilation space (10) can be compensated for via openings (9) in the rafters (3) and longitudinal battens (8). The special arrangement of the insulating panels (4) results in closed air spaces (11) which are used for heat insulation. <IMAGE>

Description

Bekannt sind Holzdächer mit zwischen den Sparren eingebauter Wärmedämmung die am Ort zusammengebaut sind, wobei eine zwi­ schen den Sparren verspannte Unterspannbahn die zusätzliche Feuchtigkeitssperre bildet. Diese Feuchtigkeitssperre muß beid­ seitig belüftet sein und ist zeitaufwendig örtlich einzubauen.Wooden roofs with built-in between the rafters are known Thermal insulation that are assembled on site, a two the additional roofing tensioned under the rafters Moisture barrier forms. This moisture barrier must be both ventilated on both sides and is time-consuming to install locally.

Der Erfindung liegt die Aufgabe zugrunde ein Dachelement zu entwickeln, daß möglichst vollständig im Werk vorgefertigt wer­ den kann, so daß kostenaufwendige Baustellenarbeiten weitgehend entfallen.The invention has for its object a roof element develop that prefabricated as completely as possible in the factory that can, so that costly construction site work largely omitted.

Die Erfindung wird erfindungsgemäß durch die Merkmale im Pa­ tentanspruch 1 gelöst, zweckmäßige Ausgestaltung der Erfin­ dung sind Gegenstand der Unteransprüche.The invention is according to the invention by the features in Pa Claim 1 solved, appropriate embodiment of the inven are subject of the subclaims.

Die Erfindung ist nachfolgend anhand von verschiedenen in den Zeichnungen dargestellten Ausführungsbeispielen erläutert. Es zeigtThe invention is based on various in the Illustrated embodiments illustrated. It shows

Fig. 2 einen Schnitt nach Linie II-II, Fig. 2 shows a section according to line II-II,

Fig. 3 einen Schnitt nach Linie I-I, Fig. 3 shows a section along line II,

Fig. 4 einen Teilquerschnitt durch einen Sparren. Fig. 4 shows a partial cross section through a rafter.

Bei den verschiedenen Ausführungsbeispielen sind gleiche Bau­ teile durch gleiche Bezugszeichen gekennzeichnet.In the different embodiments, the same construction parts identified by the same reference numerals.

Die Dachelemente (1) sind für jede Dacheindeckung geeignet. Sie werden vollständig im Werk vorgefertigt und bestehen aus unteren Abschlußplatten (2), im allgemeinen Spanplatten, die schubfest mit den Sparren (3) verbunden sind und mittragen, der Dämmung (4), auf der die Feuchtigkeitssperre (7) aufliegt und feldweise höhenversetzt über den Hölzern (3) bzw. Latten (8) en­ det und dort befestigt sind, den Latten (8), die mechanisch mit den Hölzern (3) verbunden sind, z. B. durch Nägel (12) und mit­ tragen und den Dachlatten (5) die in doppeltem Abstand liegen und gegenüber den Latten der Nachbarplatte (1) versetzt ange­ ordnet sind, so daß der Zwischenraum (13) zwischen benachbarten Dachelementen (1) erst mit den Zwischenlatten (14) verschlossen wird. Dadurch wird durch den Zwischenraum (13) sowohl die Ver­ bindung der Dachelemente mit der Unterkonstruktion als auch die Abdichtung des Längsstoßes der Abschlußplatten (2) und da­ nach der örtliche Einbau der Wärmedämmung des Zwischenraumes (13) möglich. Außerdem werden die Zwischenlatten (14) durch den geringen Sparrenabstand im Endfeld eingespannt und ver­ binden durch Übergreifen zur Nachbarplatte die Dachelemente (1) untereinander.The roof elements ( 1 ) are suitable for every roof covering. They are completely prefabricated in the factory and consist of lower end panels ( 2 ), generally chipboard, which are connected to the rafters ( 3 ) in a shear-resistant manner and support them, the insulation ( 4 ) on which the moisture barrier ( 7 ) rests and which is offset in height by fields the woods ( 3 ) or slats ( 8 ) are det and fixed there, the slats ( 8 ), which are mechanically connected to the woods ( 3 ), for. B. by nails ( 12 ) and with and the roof battens ( 5 ) which are at twice the distance and are offset from the battens of the neighboring panel ( 1 ), so that the space ( 13 ) between adjacent roof elements ( 1 ) only with the intermediate slats ( 14 ) is closed. As a result, both the connection of the roof elements with the substructure and the sealing of the longitudinal joint of the end plates ( 2 ) and since the local installation of the thermal insulation of the space ( 13 ) is possible through the space ( 13 ). In addition, the intermediate battens ( 14 ) are clamped in the end panel by the small rafter spacing and connect the roof elements ( 1 ) to one another by reaching over to the neighboring panel.

Die Längslatten (8) und Sparren (3) erhalten Ausnehmungen (9), durch die das evtl. vorhandene Dampfdruckgefälle zwischen Wärmedämmung (4) und Entlüftungsraum (10) sich ausgleichen und dadurch Kondenswasser im Dämmbereich vermieden werden kann. Evtl. sich bildendes Kondenswasser an der Dachdeckung wird auf die Feuchtigkeitssperre abtropfen und problemlos von dieser abgeleitet.The longitudinal battens ( 8 ) and rafters ( 3 ) are provided with recesses ( 9 ) through which the steam pressure drop between the thermal insulation ( 4 ) and the ventilation space ( 10 ) can be balanced out and condensation in the insulation area can be avoided. Possibly. Condensate that forms on the roof covering will drip onto the moisture barrier and be easily removed from it.
