Abstract

The web for covering roofs consists of a carrier of glass fabric, of a mat, preferably a glass mat, a glass mesh mat (scrim), and a sealing layer of polymer bitumen. To provide a weldable polymer bitumen web which has not only a high sealing action and a long life but can also be laid easily and in a time-saving manner, it is proposed according to the invention that the weldable web has a closed, homogeneous sealing layer (1), to the top of which the carrier (2) is applied which is impregnated to saturation with polymer bitumen, and the underside of which is designed as a separation and (vapour pressure) compensation layer. The separation and (vapour pressure) compensation layer is a channel system (3) which consists of mutually crossing longitudinal grooves (4) and transverse grooves (5).

Description

Die Erfindung betrifft eine Polymerbitumen-Schweißbahn zur Abdeckung von Dächern, welche aus einem Träger aus Glasgewebe, aus Vlies, vorzugsweise Glasvlies, Glasgittervlies (Glasgelege) und einer Dichtungsschicht aus Polymerbitumen besteht, deren Unterseite als Trenn- und (Dampfdruck-) Ausgleichsschicht ausgestaltet ist.The invention relates to a polymer bitumen welding sheet for covering roofs, which consists of a carrier made of glass fabric, nonwoven, preferably glass fleece, glass grid fleece (glass scrim) and a sealing layer made of polymer bitumen, the underside of which is designed as a separating and (vapor pressure) compensating layer.

Die herkömmlichen Polymerbitumen-Schweißbahnen weisen eine Trägereinlage aus Chemiefaservlies, Glasgewebe, Glasvlies usw. auf mit einer oberen und unteren Deckschicht (=Dichtungsschicht) aus Polymerbitumen, wobei sich der Träger im mittleren Drittel der Dichtungsschicht befindet.The conventional polymer bitumen welding sheets have a carrier insert made of synthetic fiber fleece, glass fabric, glass fleece etc. with an upper and lower cover layer (= sealing layer) made of polymer bitumen, the carrier being located in the middle third of the sealing layer.

Diese bekannten Schweißbahnen haben den Nachteil, daß sich die Deckschichten vom Träger abheben können (Spaltung der Dichtungsschicht), so daß die Schweißbahn nicht mehr der Norm entspricht und außerdem deren Dichtigkeit nicht mehr gewährleistet ist.These known welding tracks have the disadvantage that the cover layers can stand out from the support (cleavage of the sealing layer), so that the welding track no longer conforms to the norm and, moreover, its tightness is no longer guaranteed.

Auf die obere Deckschicht wird als Oberflächenschutz üblicherweise Schiefersplitt aufgebracht, welcher eine gewisse Kerbwirkung auf die obere Deckschicht ausübt und diese somit schwächt. Ein weiterer Nachteil dieses Oberflächenschutzes ist das Abspringen des Splitts durch die hohe Temperatur beim Schweißvorgang, was besonders im Überlappungsbereich der Bahnen gefährlich ist. Denn es ist nicht zu vermeiden, daß Splitt in den Überlappungsbereich gerät, wodurch eine geschlossene, homogene Verbindung der Dachbahnen im Nahtbereich nicht mehr gewährleistet ist.Slate chippings are usually applied to the upper cover layer as surface protection, which exerts a certain notch effect on the upper cover layer and thus weakens it. Another disadvantage of this surface protection is that the chips split off due to the high temperature during the welding process, which is particularly dangerous in the overlap area of the webs. Because it cannot be avoided that chippings get into the overlap area, as a result of which a closed, homogeneous connection of the roofing membranes in the seam area is no longer guaranteed.

Durch die FR-A-2 544 361 ist eine Bitumenbahn zur Abdeckung von Bauwerksflächen bekannt, welche an ihrer Auflagefläche mit einer Folie belegt ist. Die Bitumenbahn und die Folie sind an ihren Auflageflächen mit einem Kanalsystem aus in Längs- und Querrichtung der Bitumenbahn verlaufenden, an ihren Kreuzungsstellen einander durchdringenden Nuten ausgerüstet.FR-A-2 544 361 discloses a bitumen sheet for covering building surfaces, which is covered with a film on its contact surface. The bitumen sheet and the film are equipped on their contact surfaces with a channel system consisting of grooves which run in the longitudinal and transverse directions of the bitumen sheet and penetrate one another at their crossing points.

Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Polymerbitumen-Schweißbahn der eingangs genannten Art zu schaffen, welche unter Vermeidung vorerwähnter Nachteile nicht nur über eine hohe Abdichtungswirkung sowie eine lange Lebensdauer verfügt, sondern darüber hinaus auch einfach und zeitsparend zu verlegen ist.Starting from this prior art, the invention has for its object to provide a polymer bitumen welding sheet of the type mentioned, which not only has a high sealing effect and a long service life, while avoiding the aforementioned disadvantages, but also easy and time-saving to install is.

Erfindungsgemäß wird dies dadurch erreicht, daß die Schweißbahn eine geschlossene, homogene Dichtungsschicht aufweist, auf deren Oberseite der Träger aufgebracht ist, welcher vor dem Aufbringen satt mit Polymerbitumen getränk ist. Die Dichtungsschicht kann beispielsweise eine Stärke von 4 mm und der Träger von 1 mm aufweisen. Durch diese Ausgestaltung ergibt sich nicht nur eine hohe Abdichtungswirkung infolge der homogenen Dichtungsschicht, sondern auch eine zusätzliche Schutzfunktion des eigentlichen Trägers, eben über seine Tragfunktion hinaus, so daß nach unten hin nicht nur die Abdichtungswirkung verbessert wird, sondern nach oben hin auch der Schutz gegen mechanische Einwirkung sowie gegen Sonnenstrahlen und Schocks infolge starker Temperaturunterschiede. Durch die erfindungsgemäße Ausgestaltung wird außerdem die Alterungsbeständigkeit der Bahn erhöht.According to the invention, this is achieved in that the welding track has a closed, homogeneous sealing layer, on the top of which the support is applied, which is saturated with polymer bitumen before application. The sealing layer can for example have a thickness of 4 mm and the carrier of 1 mm. This configuration not only results in a high sealing effect due to the homogeneous sealing layer, but also an additional protective function of the actual wearer, just beyond its supporting function, so that not only the sealing effect is improved downwards, but also the protection against it upwards mechanical impact as well as against sun rays and shocks due to large temperature differences. The inventive design also increases the aging resistance of the web.

Gemäß einer Ausgestaltung der Erfindung kann die Trenn- und (Dampfdruck-) Ausgleichsschicht ein Kanalsystem sein, welches aus einander kreuzenden Längs- und Quernuten besteht. Das so gebildete Kanalsystem kann mit Talkum abgestreut sein oder aber vorteilhaft auch mit einer Folie kaschiert sein, welche sich bis in die Nuten des Kanalsystems hinein erstreckt. Das Kanalsystem bewirkt einen einwandfreien Dampfdruckausgleich, dessen Nuten sämtlich miteinander in Verbindung stehen. Diese Ausführungsart ist besonders geeignet bei normal anfallender Bau-und Nutzungsfeuchte.According to one embodiment of the invention, the separating and (vapor pressure) compensating layer can be a channel system which consists of longitudinal and transverse grooves crossing one another. The channel system formed in this way can be sprinkled with talc or advantageously also laminated with a film which extends into the grooves of the channel system. The duct system ensures perfect vapor pressure compensation, the grooves of which are all connected to one another. This type of construction is particularly suitable for normal building and usage moisture.

Gemäß einer Weiterbildung der Erfindung kann die Trenn- und (Dampfdruck-) Ausgleichsschicht auch aus noppenförmigen Vorsprüngen gebildet sein, welche auf die Unterseite der Dichtungsschicht aufgebracht sind und beispielsweise eine Höhe von 4-5 mm aufweisen. Die noppenförmigen Vorsprünge bestehen vorzugsweise aus dem gleichen Material wie die Dichtungsschicht. Diese noppen schaffen eine hohlraumreiche Trenn- und (Dampfdruck-) Ausgleichsschicht. Diese Ausführungsart ist besonders geeignet bei anfallender hoher Nutzungsfeuchte, z.B. in Waschkauen, Großwäschereien, Autowaschanlagen usw.According to a development of the invention, the separating and (vapor pressure) compensation layer can also be formed from knob-shaped projections which are applied to the underside of the sealing layer and have a height of 4-5 mm, for example. The knob-shaped projections are preferably made of the same material as the sealing layer. These nubs create a void-rich separation and (vapor pressure) compensation layer. This type of construction is particularly suitable in the event of high usage moisture, e.g. in laundry chews, large laundries, car washes, etc.

Im vorteilhafter Weiser weist die Dichtungsschicht an ihrem einen Längs- und/oder einem Querrand einen ebenen Kleberand zum überlappenden Verbinden benachbarter Bahnen auf.In an advantageous manner, the sealing layer has on its one longitudinal and / or a transverse edge a flat adhesive edge for the overlapping connection of adjacent webs.

Die als Kleber dienenden Längs- und Querränder der Dichtungsschicht sind frei von Längs- und Quernuten einerseits und von Noppen andererseits, so daß sich eine flächige Auflage auf den zugeordneten Randbereichen der Träger der benachbarten Schweißbahnen ergibt.The longitudinal and transverse edges of the sealing layer, which serve as adhesives, are free of longitudinal and transverse grooves on the one hand and of knobs on the other hand, so that there is a flat support on the associated edge regions of the supports of the adjacent welding tracks.

Die neuerungsgemäße Polymerbitumen-Schweißbahn eignet sich besonders auch als langzeitige Eindeckung nach Art der einlagigen Dachabdichtung aus hochpolymeren Bahnen.The polymer bitumen welding membrane according to the innovation is also particularly suitable as long-term covering according to the type of single-layer roof sealing made of high-polymer membranes.

Ausführungsbeispiele der Erfindung sind an Hand der Zeichnung näher erläutert, und zwar zeigt:

  • Figur 1 eine Ansicht der Schmalseite einer Polymerbitumen-Schweißbahn mit Kanalsystem und
  • Figur 2 eine Ansicht der Schmalseite einer Polymerbitumen-Schweißbahn mit Noppensystem.
Embodiments of the invention are explained in more detail with reference to the drawing, which shows:
  • Figure 1 is a view of the narrow side of a polymer bitumen welding sheet with channel system and
  • Figure 2 is a view of the narrow side of a polymer bitumen welding sheet with knob system.

Mit 1 ist die geschlossene, homogene Dichtungsschicht aus Polymerbitumen bezeichnet, auf deren Oberseite der Träger 2 aus vorzugsweise Glasgewebe, Glasvlies, Glasgittervlies (Glasgelege) aufgebracht ist. Vor Aufbringung des Trägers 2 auf die homogene Dichtungsschicht 1 erfährt der Träger 2 eine satte Tränkung, d.h. Imprägnierung mit dem Polymerbitumen.1 with the closed, homogeneous sealing layer made of polymer bitumen is referred to, on the top of which the carrier 2 made of preferably glass fabric, glass fleece, glass grid fleece (glass scrim) is applied. Before the carrier 2 is applied to the homogeneous sealing layer 1, the carrier 2 is saturated, ie impregnated with the polymer bitumen.

Bei dem Ausführungsbeispiel nach Figur 1 ist die Dichtungsschicht 1 an ihrer Unterseite mit einem Kanalsystem 3 ausgerüstet, welches aus einander kreuzenden Längsnuten 4 und Quernuten 5 besteht.In the embodiment of Figure 1, the sealing layer 1 is equipped on its underside with a channel system 3, which consists of intersecting longitudinal grooves 4 and 5 transverse grooves.

Die Unterseite ist mit einer Folie 6 abgedeckt, welche sich flächig in die Längsnuten 4 und Quernuten 5 erstreckt und somit voll auf der Unterseite der Dichtungsschicht 1 anliegt.The underside is covered with a film 6, which extends flatly into the longitudinal grooves 4 and transverse grooves 5 and thus lies fully against the underside of the sealing layer 1.

Das so gebildete Kanalsystem 3 stellt eine hochwirksame Trenn- und (Dampfdruck-) Ausgleichsschicht dar.The channel system 3 formed in this way represents a highly effective separating and (vapor pressure) compensation layer.

Bei der Ausführung nach Figur 2 sind auf die Unterseite der Dichtungsschicht 1 noppenförmige Vorsprünge 7 aufgebracht, welche etwa eine Höhe von 4-5 mm aufweisen. Diese noppenförmigen Vorsprünge 7 bestehen aus dem gleichen Material wie die Dichtungsschicht 1. Bei dieser Ausführung bilden die noppenförmigen Vorsprünge 7 die Trenn- und (Dampfdruck-) Ausgleichsschicht.In the embodiment according to FIG. 2, knob-shaped projections 7 are applied to the underside of the sealing layer 1, which have a height of approximately 4-5 mm. These knob-shaped projections 7 are made of the same material as the sealing layer 1. In this embodiment, the knob-shaped projections 7 form the separating and (vapor pressure) compensation layer.

Bei beiden Ausführungsbeispielen nach Figur 1 und 2 weist die Dichtungsschicht 1 an ihrem einen Längsrand sowie an dem nicht weiter dargestellten Querrand einen Kleberand 8 auf, welcher die Überlappungsbreite zum Befestigen auf dem Träger der benachbarten Schweißbahn bildet. Um eine flächige Auflage zu erreichen, ist der Kleberand 8 eben ausgebildet, d.h. in diesen erstrecken sich weder Längsnuten 4 noch Quernuten 5 einerseits, noch Noppen 7 andererseits.In both exemplary embodiments according to FIGS. 1 and 2, the sealing layer 1 has an adhesive edge 8 on its one longitudinal edge and on the transverse edge (not shown further), which forms the overlap width for fastening on the carrier of the adjacent welding track. In order to achieve a flat support, the adhesive edge 8 is flat, i.e. Neither longitudinal grooves 4 nor transverse grooves 5 on the one hand nor knobs 7 on the other extend in these.

Benachbarte Schweißbahnen schließen somit so aneinander an, daß sich ein zusammenhängendes Kanalsystem auf der gesamten Dachfläche od.dgl. ergibt.Adjacent welding tracks are thus connected to one another in such a way that a coherent channel system or the like on the entire roof surface. results.
