Description
DachplatteRoof panel
Die Erfindung bezieht sich auf eine Dachplatte aus geschäumtem Polystyrol zur Anbringung an der Außenseite einer Dachabdichtung.The invention relates to a roof panel made of foamed polystyrene for attachment to the outside of a roof waterproofing.
Diese sogenannten Umkehrdachplatten sind relativ hohen Beanspruchungen ausgesetzt, da sie sich auf der Wetterseite der Dachabdichtung befinden. Um die Wasseraufnahme der Platte in Grenzen zu halten, war es daher bisher notwendig, diese aus extrudiertem Polystyrol herzustellen. Dies ist insofern nachteilig, als es die Gestaltungsmöglichkeiten für die Raumform der Platte stark einschränkt.These so-called inverted roof panels are exposed to relatively high stresses because they are located on the weather side of the roof waterproofing. In order to limit the water absorption of the panel, it was therefore previously necessary to manufacture them from extruded polystyrene. This is disadvantageous in that it severely limits the design options for the spatial shape of the panel.
Überraschend ist es gelungen, die Anforderungen an eine Umkehrdachplatte dadurch zu erfüllen, daß zumindest die gebäudeseitige Oberfläche der aus expandiertem Polystyrol bestehenden Platte mit einer Deckschicht aus einer Polystyrolfolie (Schäumhaut) versehen ist.Surprisingly, it has been possible to meet the requirements for an inverted roof panel by providing at least the building-side surface of the panel made of expanded polystyrene with a covering layer made of a polystyrene film (foam skin).
Die Herstellung der Platte aus expandiertem Polystyrol ermöglicht es, insbesondere die Hauptflächen der Platte so auszubilden, daß zwischen Dämmplatte und Dachabdichtung eingedrungenes Wasser entlang dieser Hauptflächen abgeleitet werden kann. Insbesondere dienen dazu Scharen parallel zueinander verlaufender Nuten, von denen eine in der Neigungsrichtung des Flachdaches vorzusehen sein wird. Wenn die von den Nuten begrenzten Vorsprünge der Platte mit Abstand vom Rand der Plattenhauptflache enden, ist sichergestellt, daß auch an den aneinandergrenzenden Plattenrändern kein Wasser gestaut wird.The manufacture of the panel from expanded polystyrene makes it possible, in particular, to design the main surfaces of the panel in such a way that water that has penetrated between the insulation panel and the roof waterproofing can be drained along these main surfaces. In particular, this is achieved by means of sets of grooves running parallel to one another, one of which will be provided in the direction of the flat roof's slope. If the projections of the panel delimited by the grooves end at a distance from the edge of the main surface of the panel, it is ensured that no water is trapped at the adjacent edges of the panel.
Weitere Einzelheiten der Erfindung werden anschließend anhand der Zeichnungen erläutert.Further details of the invention are explained below with reference to the drawings.
In dieser ist Fig. 1 eine Draufsicht auf die dachferne Oberseite einer Dachplatte, Fig.. 2 eine schaubildliche Darstellung des in Fig. 1 darges» tell ten Ausschnittes, Fig. 3 eine Ansicht der dachseitigen Hauptfläche der Platte und Fig. 4 ein Detail des zugehörigen Querschnittes .In this, Fig. 1 is a plan view of the top side of a roof panel away from the roof, Fig. 2 is a diagrammatic representation of the section shown in Fig. 1, Fig. 3 is a view of the main surface of the panel on the roof side and Fig. 4 is a detail of the corresponding cross section.
Die erfindungsgemäße Platte ist auf einer in Fig. 1 dargestellten Hauptfläche mit Vorsprüngen 1 versehen, zwischen denen Scharen einander im rechten Winkel kreuzender Nuten 2 verlaufen. Die Nuten reichen nicht ganz bis zum Rand 3 der die VorSprünge 1 tragenden Hauptfläche der Platten. Dadurch entsteht ein Absatz 4, in welcher auch bei ungenauem Zusammenfügen benachbarter Platten eine Ableitung des durch die Nuten zum Rand der Platte geführten Wassers gewährleisten. Typische Abmessungen für die Nuten der in Fig. 1 und 2 dargestellten Oberseite der Platte wären bei einer Tiefe der Nuten von 3 mm und einer Breite von 5 mm gegeben.The plate according to the invention is provided with projections 1 on a main surface shown in Fig. 1, between which groups of grooves 2 run that cross each other at right angles. The grooves do not reach all the way to the edge 3 of the main surface of the plate that bears the projections 1. This creates a step 4, in which the water that is led through the grooves to the edge of the plate is drained away even if adjacent plates are not joined together precisely. Typical dimensions for the grooves on the top side of the plate shown in Fig. 1 and 2 would be a groove depth of 3 mm and a width of 5 mm.
Die in Fig. 3 dargestellte der Dachhaut zugewandte Hauptfläche der Platte ist zusätzlich zu den bereits besprochenen Scharen von Nuten 2 auch noch mit längsverlaufenden Nuten 21 versehen, welche beim Verlegen der Platte vorzugsweise in Richtung der (geringen) Dachneigung verlaufen. Die typische Tiefe der Nuten 2' beträgt 5 mm, die Breite etwa 15 mm.The main surface of the panel facing the roof covering shown in Fig. 3 is provided with longitudinal grooves 21 in addition to the already discussed sets of grooves 2, which preferably run in the direction of the (low) roof pitch when the panel is laid. The typical depth of the grooves 2' is 5 mm, the width about 15 mm.
Wesentlich ist, daß zumindest die Unterseite der Platten, vorzugsweise aber auch die in Fig. 1 und 2 dargestellte Oberseite, durch eine dünne Polystyrolfolie 5 (Schäumhaut) abgeschlossen ist, welche mit dem Kern 6 der Platte fest verbunden ist. Diese Folie 5 hat beispielsweise eine Dicke von 0,15 mm bis 0,3 mm. Ihre Dichte liegt in der Größenordnung von 800 bisIt is essential that at least the underside of the panels, but preferably also the top side shown in Fig. 1 and 2, is closed off by a thin polystyrene film 5 (foam skin) which is firmly connected to the core 6 of the panel. This film 5 has a thickness of 0.15 mm to 0.3 mm, for example. Its density is in the order of 800 to
1000 kg/m3 verglichen mit etwa 3 0 kg/m3 für den Kern 6 der Platte. Durch diese Beschichtung erhält die Platte eine Widerstandsfähigkeit gegen Wasseraufnahme, wie sie bisher nur bei extrudierten Platten erreichbar war. Die feste Verbindung von Deckschicht 5 und Kern 6 der Platte entsteht dadurch, daß die Deckschicht 5 in der Expansionsform der Platte eingebracht und mit den Ausgangsmaterialien der Platte überschichtet wird, sodaß beim Bedampfen und Schäumen eine innige Verbindung der Plattenbestandteile entsteht.1000 kg/m 3 compared to about 30 kg/m 3 for the core 6 of the board. This coating gives the board a resistance to water absorption that was previously only possible with extruded boards. The firm connection between the cover layer 5 and the core 6 of the board is created by the cover layer 5 being introduced in the expansion form of the board and being covered with the base materials of the board, so that an intimate connection between the board components is created during steaming and foaming.
Wichtig ist vor allem die Beschichtung der Plattenunterseite, da entlang dieser die von der Dachhaut abgewiesene Feuchtigkeit zur Traufe gelangen muß und sich im Zwischenraum von Dach und Dichtung keine permanente Feuchtigkeit ausbilden darf. Auch an der Oberseite der Platte ist die Anordnung einer Deckschicht 5 zweckmäßig, da diese die mechanische Festigkeit und auch die Formbeständigkeit zusätzlich erhöht. Vor allem ist auch die Oberflächenausbildung an der Plattenunterseite von Wichtigkeit, da deshalb kein geschlossener Wasserfirlm entstehen und sich auch kein unzulässiger Dampfdruck aufbauen kann.The coating on the underside of the panel is particularly important, as the moisture repelled by the roof covering must reach the eaves along this surface and no permanent moisture must form in the space between the roof and the seal. It is also advisable to apply a covering layer 5 to the top of the panel, as this increases the mechanical strength and also the dimensional stability. The surface finish on the underside of the panel is also particularly important, as this prevents a closed water film from forming and impermissible vapor pressure from building up.
