Abstract

The fire arrester path is layed in addition to conventional insulation and roof paths on a slope of a roof. It is intended to prevent the development of surface fires or at least to retard them. It must simultaneously form a moisture barrier. To this effect, it includes two plastic sheets surrounding an aluminum foil used as a carrier path. A glass fiber web with a certain crystalline bond water contents is laminated on a plastic sheet. In case of fire, water is vaporized. Water vapor resulting therefrom prevents or retards a surface fire or a break-through fire.

Description

Gebiet der ErfindungField of the Invention

Die Erfindung betrifft eine Brandschutzbahn mit Dampfsperre zum Belegen von Dach- und Wandflächen und dergleichen mit einer tragenden Bahn und einer auf diese aufkaschierten Flammschutzbahn aus einem Glasfaservlies mit einem Gehalt an kristallin gebundenem Wasser.The invention relates to a fire protection membrane with a vapor barrier for covering roof and wall surfaces and the like with a load-bearing membrane and a flame-retardant membrane made of a non-woven glass fiber and containing crystalline-bound water.

Stand der TechnikState of the art

Auf Dachkonstruktionen und -bahnen, die keine «harte Bedachung» im Sinne der DIN 4102 und damit nicht beständig gegenüber Flugfeuer und strahlender Wärme sind, bringt man sogenannte Brandschutzbahnen an. Mit diesen Brandschutzbahnen erreicht man die gewünschte «harte Bedachung». Die Brandschutzbahnen werden zwischen dem Dämmstoff und einer Oberlage eingelegt. Hauptsächlich werden sie bei Kunststoffolien oder hochpolymeren Bahnen verwendet. Ein Beispiel für eine auf diese Weise erzielte «harte Bedachung» wird in der DE-A-3 220 821 beschrieben.So-called fire protection membranes are installed on roof constructions and membranes that are not «hard roofing» in the sense of DIN 4102 and therefore not resistant to flight fire and radiant heat. With these fire protection membranes you can achieve the desired «hard roofing». The fire protection membranes are placed between the insulation and an upper layer. They are mainly used for plastic films or high polymer sheets. An example of a "hard roof" achieved in this way is described in DE-A-3 220 821.

Es wird auch vorgeschlagen (nicht veröffentlichte DE-A-3 322 283), Flachdächer mit einem Brandschutzanstrichmittel, das Elastomerbitumen enthält, gegen einen Band von oben zu schützen. Dieser Brandschutzanstrich wirkt ähnlich wie eine Kiesaufschüttung.It is also proposed (unpublished DE-A-3 322 283) to protect flat roofs against a tape from above with a fire protection paint containing elastomer bitumen. This fire protection coating works similarly to a gravel fill.

Bei Dächern und Flachdächern, insbesondere wenn grosse Flächen abgedeckt werden, wird als Unterkonstruktion häufig ein Stahlprofilblech verwendet. Als Dämmstoff wird dabei aus bauphysikalischen Gründen überwiegend EPS-Hartschaum verwendet. EPS bedeutet dabei expandiertes Polystyrol. Polystyrol ist ein Thermoplast. In bezug auf Windlast, Feuchtigkeitsaufnahme, Elastizität, Preiswürdigkeit und gute Verlegemöglichkeit stellt dieser Kunstschaumstoff die optimale Lösung dar.For roofs and flat roofs, especially if large areas are covered, a steel profile sheet is often used as a substructure. For reasons of building physics, EPS rigid foam is mainly used as the insulation material. EPS means expanded polystyrene. Polystyrene is a thermoplastic. In terms of wind load, moisture absorption, elasticity, value for money and good installation options, this synthetic foam is the optimal solution.

Durch Untersuchungen des IVH, Industrieverband Hartschaum e.V., Heidelberg, und des Landes Nordrhein-Westfalen ist es bekannt, dass sich als Dämmstoffe auf Stahlprofilblechen verlegte Thermoplaste in der Anfangsphase eines Brandes besonders günstig verhalten. In der Anfangsphase eines Brandes sintern oder zerfliessen sie und nehmen dadurch Wärme auf. Dadurch wird der Übergang der Wärme auf das Stahlprofilblech verzögert. Man spricht davon, dass die Temperatur nach oben abfliesst. Bei anhaltendem Brand wird die Dachhaut jedoch stärker belastet. Nach einem Wegbrennen oder Verschwinden des Dämmstoffes schlägt die Temperatur durch. Bei länger anhaltendem Brand kann es zu einem Durchbrand in der Fläche kommen. In der Endphase des Brandes, wenn das Stahlprofilblech einstürzt, ist es dann gleichgültig, ob als Dämmstoff ein schmelzender Thermoplast oder ein nicht schmelzender Werkstoff verwendet wurde.Investigations by the IVH, Industrieverband Hartschaum e.V., Heidelberg, and the state of North Rhine-Westphalia have shown that thermoplastics laid on insulating steel sheets behave particularly favorably in the initial phase of a fire. In the initial phase of a fire, they sinter or melt and absorb heat. This delays the transfer of heat to the steel profile sheet. It is said that the temperature flows upwards. If the fire persists, however, the roof skin is subjected to greater stress. If the insulation material burns or disappears, the temperature will break through. If the fire lasts longer, the surface may burn. In the final phase of the fire, when the steel profile sheet collapses, it makes no difference whether a melting thermoplastic or a non-melting material was used as the insulation material.

Um die verhältnismässig häufig auftretende Mittelphase des Brandes gut zu überstehen, werden immer wieder Dämmstoffe aus einem nicht schmelzenden Werkstoff verwendet. In den USA werden zum Beispiel Gipskartonplatten und auf diesen zusätzlich EPS-Platten auf die Stahlprofilbleche aufgelegt. Dies erfolgt in zwei Arbeitsgängen. Deshalb ist es verhältnismässig teuer. Weiter muss, um den bauphysikalischen Forderungen zu entsprechen, im Regelfall eine Dampfsperre unter den Gipskartonplatten angeordnet werden.In order to survive the relatively common middle phase of the fire, insulation materials made of a non-melting material are used time and again. In the USA, for example, gypsum plasterboard and, in addition, EPS panels are placed on the steel profile sheets. This is done in two steps. Therefore it is relatively expensive. Furthermore, in order to meet the building physics requirements, a vapor barrier must usually be placed under the plasterboard.

Weiter ist es bekannt, als Dampfsperre eine beidseitig mit Bitumen beschichtete Aluminiumfolie auf dem Stahlprofilblech anzuordnen. Wegen der Beschichtung mit Bitumen brennt diese Folie jedoch leicht und trägt nicht zum Brandschutz bei.It is also known to arrange an aluminum foil coated on both sides with bitumen on the steel profile sheet as a vapor barrier. However, due to the bitumen coating, this film burns easily and does not contribute to fire protection.

Kurze Beschreibung der ErfindungBrief description of the invention

Hiervon ausgehend stellt sich für die vorliegende Erfindung die Aufgabe, eine Dachbahn zu entwikkeln, die sowohl eine Brandschutzbahn als auch eine Dampfsperre bildet. Dabei soll die Brandschutzbahn so ausgerüstet sein, dass bei einem Brand von unten ein Durchbrand bis zum Einsturz des Stahlprofilbleches mit Sicherheit verhindert wird. Bei einer Brandschutzbahn der eingangs genannten Gattung ergibt sich die Lösung für diese Aufgabe nach der Erfindung dadurch, dass die tragende Bahn eine Aluminiumfolie ist, Kunststoffolien auf beide Seiten der Aluminiumfolie aufkaschiert sind, das einen Gehalt an kristallin gebundenem Wasser aufweisende Glasfaservlies auf eine der Kunststoffolien aufkaschiert und auf seiner freien Oberfläche mit einer Wachsschicht beschichtet ist. Das Glasfaservlies, das das kristallin gebundene Wasser enthält, ist zum Beispiel gemäss der DE-A-3 220 821 ausgebildet. Diese erfindungsgemässe Brandschutzbahn mit Dampfsperre wird über der tragenden Dachkonstruktion, zum Beispiel mit Stahlprofilblech, und unter der Dämmbahn verlegt.Proceeding from this, the object of the present invention is to develop a roofing membrane which forms both a fire protection membrane and a vapor barrier. The fire protection membrane should be equipped in such a way that in the event of a fire from below, burn-through until the steel profile sheet collapses is reliably prevented. In the case of a fire protection sheet of the type mentioned at the outset, the solution to this problem according to the invention results from the fact that the supporting sheet is an aluminum foil, plastic foils are laminated onto both sides of the aluminum foil, and the glass fiber fleece containing crystalline water is laminated onto one of the plastic foils and is coated on its free surface with a wax layer. The glass fiber fleece, which contains the crystalline water, is designed, for example, according to DE-A-3 220 821. This fire protection membrane with vapor barrier according to the invention is laid over the load-bearing roof structure, for example with steel profile sheet, and under the insulation membrane.

Die auf der freien Oberfläche des Glasfaservlieses aufgebrachte Wachsschicht ist in einer zweckmässigen Ausgestaltung wasserabweisend, aber wasserdampfdurchlässig. Damit wird sichergestellt, dass das in dem Glasfaservlies kristallin gebundene Wasser oder das Brandschutzmittel während des Verlegens auf der Baustelle nicht ausgeschwemmt wird. Mit diesem Merkmal wird eine ausreichende Feuchtigkeitssicherheit für die Verlegezeit auf der Baustelle erreicht. Zu erwähnen ist dabei, dass die erfindungsgemässe Brandschutzbahn nach ihrem Verlegen sofort mit weiteren Bahnen abgedeckt werden kann und soll.In an expedient embodiment, the wax layer applied to the free surface of the glass fiber fleece is water-repellent but permeable to water vapor. This ensures that the water bound in the glass fiber fleece or the fire protection agent is not washed out during installation on the construction site. With this feature, sufficient moisture security is achieved for the laying time on the construction site. It should be mentioned that the fire protection membrane according to the invention can and should be covered with additional membranes immediately after it has been laid.

Zweckmässig besteht die auf die Unterseite der Aluminiumfolie aufkaschierte Kunststoffolie aus Polyester, während die auf die Oberseite aufkaschierte Kunststoffolie aus Polyäthylen besteht.The plastic film laminated onto the underside of the aluminum foil expediently consists of polyester, while the plastic film laminated onto the upper side consists of polyethylene.

Bei einem Verlegen der erfindungsgemässen Brandschutzbahn auf einem Profilblech können die dann freibleibenden Profilräume abgeschottet werden. Hierzu können Stäbe oder Würfel aus Kunststoffschaum in diese eingelegt werden. Diese Stäbe oder Würfel verschliessen die Profile oder Sicken des Profilbleches. Damit werden brennbare Gase, Rauch und dergleichen an einem Weiterströmen und einer Verbreitung gehindert. Zweckmässig sind die aus einem Kunststoffschaum bestehenden Stäbe oder Würfel mit einem Brandschutzmittel getränkt. Die Verwendung solcher Stäbe oder Würfel aus Kunststoffschaum zum Verschliessen der Profilhohlräume oder Sicken der Profilbleche ist an sich bekannt. Neu ist jedoch die Verwendung dieser Würfel oder Stäbe bei der erfindungsgemässen Brandschutzbahn. Ebenso ist es neu, diese Würfel oder Stäbe mit einem Brandschutzmittel zu behandeln oder zu tränken. Statt mit Kunststoffschaum können die freibleibenden Profilhohlräume auch mit Sand oder Kies abgeschottet werden. Dieser wird einfach in die Profilhohlräume hineingeschüttet.When the fire protection membrane according to the invention is laid on a profile sheet, the profile spaces which are then left free can be partitioned off. For this purpose, rods or cubes made of plastic foam can be inserted into them. These bars or cubes close the profiles or beads of the profile sheet. This prevents flammable gases, smoke and the like from continuing to flow and spread. The rods or cubes consisting of a plastic foam are expediently soaked with a fire protection agent. The use of such rods or cubes made of plastic foam for closing the profile cavities or beads of the profile sheets is known per se. However, the use of these cubes or rods is new in the fire protection membrane according to the invention. It is also new to treat or soak these cubes or rods with a fire protection agent. Instead of using plastic foam, the remaining free profile cavities can also be sealed off with sand or gravel. This is simply poured into the profile cavities.

Die erfindungsgemässe Brandschutzbahn hat eine hohe Reissfestigkeit. Sie kann daher auf Stahlprofilblechen bzw. Stahltrapezblechen und über deren Sicken verlegt werden. Durch die dünnen Polyäthylenfolien ist sie gegen Korrosion geschützt. Die erfindungsgemässe Brandschutzbahn lässt sich mit einem Bitumen-Kaltkleber, der selbst nur wenig brennbare Bestandteile auf das Dach bringt, aufkleben. Auch die Überlappungen zwischen benachbarten Brandschutzbahnen können mit einem Bitumen-Kaltkleber verklebt werden. Bei besonderen Brandschutzforderungen kann die Brandschutzbahn auch aufgenagelt werden. Dabei wird das gesamte Schichtenpaket einschliesslich der ersten Lage der Dachhaut aufgenagelt.The fire protection membrane according to the invention has a high tear resistance. It can therefore be laid on steel profile sheets or trapezoidal steel sheets and over their beads. It is protected against corrosion by the thin polyethylene foils. The fire protection membrane according to the invention can be stuck on with a bitumen cold adhesive which itself brings only few flammable components onto the roof. The overlaps between adjacent fire protection membranes can also be glued with a bitumen cold adhesive. For special fire protection requirements, the fire protection membrane can also be nailed on. The entire layer package including the first layer of the roof skin is nailed on.

Bei einem Brand von unten gibt die oben liegende Brandschutzbahn infolge des in dem Glasfaservlies kristallin gebundenen Wassers pro Quadratmeter zirka 200 g Wasser ab. Dies führt zu grösseren Mengen Wasserdampf. Dieser Wasserdampf füllt die Kavernen des thermoplastischen Werkstoffes, die sich durch die Temperatureinstrahlung von unten ergeben haben, so stark mit Wasserdampf, dass ein Durchbrand nicht mehr möglich ist.In the event of a fire from below, the fire protection membrane on top releases approximately 200 g of water per square meter as a result of the water crystallized in the glass fiber fleece. This leads to larger amounts of water vapor. This water vapor fills the caverns of the thermoplastic material, which have resulted from the temperature radiation from below, so strongly with water vapor that burn-through is no longer possible.

Die erfindungsgemässe Brandschutzbahn lässt sich, wie ausgeführt, unmittelbar auf Stahlprofilbleche, wie Stahltrapezbleche, verlegen. Ebenso kann sie auch auf andere brandschutzbedürftige Unterkonstruktionen aufgelegt werden. Dabei bildet sie die aus bauphysikalischen Gründen notwendige Dampfsperre und verhindert gleichzeitig, wie ausgeführt, einen Durchbrand.The fire protection membrane according to the invention can, as stated, be laid directly on steel profile sheets, such as steel trapezoidal sheets. It can also be placed on other substructures requiring fire protection. It forms the vapor barrier necessary for building physics reasons and at the same time prevents burnout, as stated.
