Description
Die Erfindung betrifft eine Dachdämmplatte aus Mineralwolle für Flachdächer gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a roof insulation board made of mineral wool for flat roofs according to the preamble of claim 1.
Bei der Dämmung von Flachdächern, inbesondere im Bereich von Industriebauten, Sportstätten und dgl. größerer Bauwerken werden bevorzugt Dachdämmplatten aus Mineralwolle verwendet, die sich durch ihre Zuverlässigkeit, Lebensdauer und einfache Handhabung bei der Verlegung sowie durch ihre gute Wärmedämmeigenschaften auszeichnen. Diese Dachdämmplatten werden auf dem Markt in Standardformaten von 1200 x 625 mm oder auch Großformaten von 1200 x 1200 mm bei variierenden Dicken von 60 bis 140 mm angeboten und weisen eine ausreichend hohe Druckfestigkeit auf, so daß die Dachdämmplatten nach deren Verlegen auf der Dachunterkonstruktion, die überwiegend aus Stahltrapezflächen gebildet ist, begangen werden können, insbesondere aber den üblichen Druckbelastungen, denen derartige Flachdächer unter den Witterungsverhältnissen in Form von Schnee und Regen ausgesetzt sind, standhalten können. Nach dem Verlegen der Dachdämmplatten auf der Dachkonstruktion wird auf die Dachdämmplatten eine Dachabdichtung aufgebracht, üblicherweise in Form von Kunststoff- oder Kautschukbahnen. Aufgrund neuerer und strengerer bauaufsichtlicher Vorschriften, insbesondere gemäß der DIN-Norm 4102-7, müssen die Flachdächer nicht nur gegen Flugfeuer und strahlende Wärme widerstandsfähig sein, um die Ausbreitung des Feuers auf dem Dach und eine Brandübertragung vom Dach in das Innere des Gebäudes bei einer von außen auf die Bedachung einwirkenden Beanspruchung zu verhindern, vielmehr verlangen die verschärften Anforderungen an das Brandverhalten, daß als zusätzliches Kriterium bei der Prüfung auf Widerstandsfähigkeit gegen Flugfeuer und strahlende Wärme auch ein Nachglimmen in der Dämmschicht eines Dachaufbaus verhindert wird. Hinzu kommt, daß aus Kosten- und Montagegründen die Dicke der als Dachabdichtung verwendeten Kunststoff- oder Kautschukbahnen immer mehr verringert wird, was es sehr schwer macht, mit herkömmlichen Dachdämmplatten die vorgeschriebene Brandprüfung aufgrund der verschärften Anforderungen an das Brandverhalten zu bestehen.When insulating flat roofs, especially in the area of Industrial buildings, sports facilities and the like. Larger structures are preferred Mineral wool roof insulation panels are used, which are characterized by their Reliability, durability and easy handling when laying as well are characterized by their good thermal insulation properties. This Roof insulation panels are on the market in standard formats of 1200 x 625 mm or large formats of 1200 x 1200 mm with varying thicknesses of 60 to 140 mm offered and have a sufficiently high compressive strength, so that the roof insulation panels after laying them on the Roof substructure, which is predominantly made of trapezoidal steel surfaces, can be committed, but especially the usual pressure loads, which such flat roofs under the weather conditions in the form of Are exposed to snow and rain. After laying the Roof insulation panels on the roof structure become one on the roof insulation panels Roof sealing applied, usually in the form of plastic or Rubber sheets. Due to newer and stricter building inspection Regulations, in particular in accordance with DIN standard 4102-7, must comply with the Flat roofs are not only resistant to flying flames and radiant heat to be the spread of fire on the roof and a fire transmission from the roof to the inside of the building with one from the outside on the roofing to prevent acting stress, rather require tightened requirements for fire behavior that as an additional Criterion for testing for resistance to flight fire and radiant heat also an afterglow in the insulation layer of a Roof structure is prevented. In addition, that from cost and Installation reasons the thickness of the plastic or used as roof sealing Rubber webs is becoming increasingly diminished, which makes it very difficult to work with conventional roof insulation panels due to the prescribed fire test to meet the stricter requirements for fire behavior.
Aufgabe der Erfindung ist es somit, Dachdämmplatten aus Mineralwolle für Flachdächer so weiterzuentwickeln, daß sie ohne großen Kostenaufwand und unter Beibehaltung der Vorteile der bislang bekannten Dachdämmplatten in bezug auf beispielsweise Robustheit und einfache Verlegung auch den verschärften Anforderungen an das Brandverhalten gerecht werden können, insbesondere ein Fortpflanzen von Glimmstellen aufgrund von beispielsweise Flugfeuer aus der Kunststoffbahn der Dachabdichtung in die Dachdämmplatte zu verhindern.The object of the invention is therefore, mineral wool roof insulation panels for Developing flat roofs so that they can be carried out without great expense and while maintaining the advantages of the previously known roof insulation boards in in terms of robustness and easy installation, too can meet stricter fire behavior requirements, especially propagation of glowing spots due to, for example Flying fire from the plastic sheet of the roof waterproofing into the roof insulation board to prevent.
Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 enthaltenen Merkmale gelöst, wobei zweckmäßige Weiterbildungen durch die in den Unteransprüchen enthaltenen Merkmale gekennzeichnet sind. This object is achieved by the in the characterizing part of Features contained claim 1 solved, expedient Developments through the features contained in the subclaims Marked are.
Nach Maßgabe der Erfindung ist vorgesehen, daß es unter Ausnutzung der Flexibilität der bei Flachdächern verwendeten Dachabdichtungen im Falle von Glimmstellen ausgehend von der Kunststoffbahn aufgrund von Flugfeuer und dgl. lokal zu einer Separierung der Dachabdichtung von der Dachdämmplatte im Bereich der Glimmstelle kommt. Dadurch wird verhindert, daß sich die Glimmstelle in die Dachdämmplatte fortpflanzen kann. Erreicht wird diese Separierung durch einen Aufschäumvorgang, der durch entsprechende Temperatureinwirkung ausgelöst wird. Die im Bereich der Glimmstelle auftretende Aufschäumung wird dadurch gewährleistet, daß zwischen der Dachdämmplatte und der Dachabdichtung eine im Brandfall aufschäumende Schicht vorgesehen ist. Diese aufschäumende Schicht kann unmittelbar auf der Dachdämmplatte aufgebracht sein und ist bevorzugt in Baueinheit mit der Dachdämmplatte ausgebildet, so daß die Dachdämmplatte als Fertigbauelement werkseitig zur Verfügung gestellt wird. Hierbei ist es zweckmäßig, daß die aufschäumende Schicht auch in oberflächennahen Bereichen der Dachdämmplatte vorgesehen ist, was für die Zuverlässigkeit des Brandschutzverhaltens der Dachdämmplatte auch nach langen Einsatzzeiten von Vorteil ist.According to the invention, it is provided that it takes advantage of the Flexibility of the roof seals used for flat roofs in the case of Glow spots starting from the plastic sheet due to flight fire and The like locally for a separation of the roof waterproofing from the roof insulation board in Area of the glow spot comes. This prevents the Can propagate glow point in the roof insulation board. This is achieved Separation by a foaming process by appropriate Temperature effect is triggered. The one in the area of the glow point Foaming occurring is ensured by the fact that between the Roof insulation panel and the roof waterproofing in the event of fire Layer is provided. This foaming layer can directly on the Roof insulation board can be applied and is preferably in a unit with the Roof insulation panel designed so that the roof insulation panel as a prefabricated element is provided at the factory. It is useful that the foaming layer also in near-surface areas of the Roof insulation board is provided, which for the reliability of the Fire protection behavior of the roof insulation board even after long periods of use Advantage is.
Für die aufschäumende Schicht eignet sich insbesondere Wasserglas mit schäumenden Substanzen, aber auch ein Thermoplast, dem Schäumungsmittel zugesetzt sind. Die Verwendung von Wasserglas ist im Bereich von Brandschutz-Bauelementen für den Einsatz in speziellen Brandschutzvorrichtungen, wie Brandschutzwänden, Brandschutztüren und dgl. bereits bekannt. So in Form von Brandschutzbauelementen mit einer Grundplatte oder Grundfolie als Trägermaterial und einem Rahmen, der quasi als verlorene Schalung für darin eingebrachtes flüssiges und pulvriges Wasserglas sowie anorganischen Füllmaterialien dient, wobei diese Brandschutzschicht dann mittels einer weiteren Deckplatte oder Deckfolie als Trägermaterial abgeschlossen ist (DE-U 7 321 823). Durch diese Einkammerung wird eine feste Einbindung der Schicht zwischen dem Trägermaterial gewährleistet und kann ferner die die Brandschutzwirkung ausübende Schicht in beliebiger Stärke hergestellt werden.Water glass is particularly suitable for the foaming layer foaming substances, but also a thermoplastic, the foaming agent are clogged. The use of water glass is in the area of fire protection components for use in special fire protection devices such as Fire walls, fire doors and the like. Already known. So in shape of fire protection components with a base plate or base film as Carrier material and a frame, the quasi as lost formwork for it introduced liquid and powdered water glass as well as inorganic Filling materials is used, this fire protection layer then using a another cover plate or cover film is completed as a carrier material (DE-U 7 321 823). This encapsulation ensures that the layer is firmly integrated guaranteed between the carrier material and can also die Fire protective layer can be made in any thickness.
Aus herstellungstechnischen Gründen ist es zweckmäßig, daß die aufschäumende Schicht durch ein Schäumverfahren auf die Dachdämmplatte aufgebracht wird. Dadurch wird insbesondere die Einhaltung gleichbleibender Dicken über die in Massenfertigung hergestellten Dachdämmplatten gewährleistet. Zweckmäßigerweise ist die aufgebrachte Schicht diffusionsoffen. Die aufschäumende Schicht wird ferner in vorteilhafter Weise derart eingestellt, daß sie bei Erreichen einer bestimmten Grenztemperatur aufschäumt, insbesondere ab einem Temperaturwert größer 170°C. Dadurch ist sichergestellt, daß die zuvor getrocknete Schicht nicht verfrüht bzw. vorzeitig bezüglich ihres Brandschutzverhaltens ausgelöst wird infolge von übermäßiger Erwärmung im Sommer oder im Wege der Trocknung der im Schäumverfahren aufgebrachten Schicht während des Herstellvorganges.For manufacturing reasons, it is appropriate that the foaming Layer is applied to the roof insulation board by a foaming process. As a result, in particular the adherence to constant thicknesses over the in Mass production roof insulation panels guaranteed. The applied layer is expediently open to diffusion. The foaming layer is also advantageously set such that it foams when a certain limit temperature is reached, in particular from a temperature value greater than 170 ° C. This ensures that the previously dried layer not prematurely or prematurely with regard to its Fire protection behavior is triggered as a result of excessive heating in the Summer or by drying the foam applied Layer during the manufacturing process.
