Definitions

  • the invention relates to a fire protection membrane, in particular for roof covering, according to the features of the preamble of claim 1 (DE-A-2 900 535).
  • insulation class A according to DIN 41 02 such as. As perlite, mineral fibers or foam glass can be used.
  • insulation materials of fire class B according to DIN 41 02. These insulation materials are intended to ensure temperature insulation, especially, of course, if there is no fire. All of this applies particularly to roof coverings, such as those currently used in large-scale commercial buildings, e.g. B. for supermarkets, are common.
  • the prior art DE-A-2900535 relates to fire protection thermal insulation, which is characterized in that it contains or consists of a hardened thermosetting synthetic resin material in which an effective amount of a finely divided, crystalline, hydrated, inorganic salt extender dispersed, which is sufficient to achieve a predetermined level of fire resistance, determined in particular according to the ASTM method E-119-76 or another fire resistance test method. wherein the hydrated extender contains at least 35% by weight water of crystallization, the major portion of which is released when heated to a temperature within the range from about 93 ° C but below about 316 ° C (200 to 600 ° F).
  • This insulation relates to sandwich structures in which adhesives are used to connect the layers.
  • the sandwich structure also includes a thermal barrier made of normal resin with hydrated salt and inorganic fillers.
  • a thermal barrier made of normal resin with hydrated salt and inorganic fillers.
  • the individual layers are firmly connected to one another.
  • the arrangement of water-releasing products behind the outer layers is intended to provide a temperature barrier to protect the combustible hard foam core. Because they are firmly connected, these layers can only be effective at certain points (passive fire protection).
  • the prior art includes DE-B-2349666 and DE-A-2 234 291 corresponding to FR-A-2 145 709.
  • DE-B-2 349 666 describes a plastic sheet, for example made of PVC soft, preferably for the sealing of unmarked, single-skin roofs or the like, with a fire protection layer, which is characterized in that the fire protection layer is embedded in the plastic sheet, in particular, that the fire protection layer is covered on all sides by the plastic sheet.
  • FR-A-2145709 relates to a non-combustible plate-shaped construction element consisting of seven layers, whereby Water is released in the event of a fire, which is used for foam formation.
  • the state-of-the-art fire protection membranes offer inadequate protection and do not guarantee that the fire will not spread.
  • the invention is therefore based on the object of eliminating the risk of burn-through and progressive fire events such as a widespread conflagration in a fire protection membrane according to the preamble of claim 1. This object is achieved by the features specified in the characterizing part of claim 1.
  • a fire protection membrane which consists of a sealing membrane of a known type, e.g. B. of the type mentioned above, on whose at least one side an additional flame retardant membrane is arranged.
  • a sealing membrane of a known type, e.g. B. of the type mentioned above, on whose at least one side an additional flame retardant membrane is arranged.
  • the type of flame retardant membrane is essential.
  • such a flame retardant membrane is understood to mean one. which is an incombustible liquid, such as e.g. B. water, in vapor form; she can also do it. emitting gases, such as B. nitrogen.
  • a flame retardant membrane in the sense of the invention for. B. a glass fiber fleece impregnated with water glass is particularly suitable.
  • a fire protection membrane of this type is known from the prior art.
  • Fire protection membranes based on glass fiber fleece are generally suitable, in which crystalline water is embedded.
  • Such water-containing substances only release their loosely bound water at around 100 ° C; sometimes they also foam up.
  • fire-emitting gases e.g. As nitrogen, are released. It has now surprisingly been found that this combined fire protection sheet completely prevents the fire from progressing on the combustible sealing sheet.
  • DE-A-2 807 697 mentions ammonium phosphate as an example, which also has a foam-forming effect.
  • resins for example urea-formaldehyde resin or the like, and carbohydrates or glue.
  • This substance composition forms a tightly coherent, porous, carbon-containing foam in the flame.
  • Such compositions of matter are also known from the following patents or documents relating to patent applications: DE-C-962 824, DE-B-1 061 011, DE-B-1065116.
  • Such a fire protection membrane according to the invention can also be used for retrofitting conventional roof coverings; for this purpose, the fire protection membrane according to the invention is placed on the top of the roof covering with the flame protection membrane.
  • the fire protection sheet is completed by an insulation sheet which is arranged on at least one free side of the flame protection sheet. Any of the aforementioned insulation materials can be used as the base material for such an insulation sheet.
  • the insulation membrane additionally provides heat insulation between the flame protection membrane with the sealing membrane and the remaining free side of the insulation membrane, which is the underside of the roof in the case of a roof.
  • a foaming flame-retardant membrane can still act between the sealing membrane and the insulating membrane as a barrier for any combustible gases from the membrane.
  • a further vapor barrier sheet can then be arranged on the remaining side of the insulation sheet.
  • a conventional propane gas burner would be held at a distance of approx. 25 cm from above onto the cover film, i.e. the sealing membrane.
  • the outer cover sheet i.e. the sealing membrane
  • the insulating material i.e. the insulation sheet
  • the size of the burn mark was a maximum of 58 cm in diameter for all structures. While the temperatures in the firing center reached values in the range of 1,000 ° C after approx. 2 to 3 minutes, they remained almost constant at this temperature over the test period.
  • the tested superstructures only continued to burn independently for a maximum of 12 to 13 minutes despite constant flaming and were only destroyed with a maximum diameter of 58 cm. At a distance of 30 or 45 cm, only temperatures of a maximum of 100 ° C were measured. The temperature of the trapezoidal sheets did not change compared to the ambient temperature.
  • the fire load is significantly reduced; flammable adhesives are not required; the combustible roof seal, i.e. the sealing membrane, is sealed off from the insulation material; if necessary, there is a vapor barrier without or with the lowest fire load underneath the insulation material, i.e. the insulation membrane.
  • the fire is practically completely hampered.
  • FIG. 1 an element of the fire protection membrane according to the invention is shown in a perspective view.
  • the sealing membrane is identified by reference number 1. It is broken up in part of its surface so as to make the surface of the flame retardant membrane 2 visible.
  • the fleece structure of the flame retardant membrane 2 is indicated by irregular patterns.
  • the smooth nature of the sealing membrane 1, however, is indicated by a thin line hatching.
  • the sealing membrane 1 is arranged on the flame retardant membrane 2.
  • a one-piece connection between the sealing membrane and the flame retardant membrane can be achieved by simple water bonding; the adhesive properties of water glass have long been known.
  • FIG. 2 shows a section of a fire protection membrane for a roof covering.
  • the sealing membrane 1 is hatched by oblique lines; the flame-retardant membrane 2 is also illustrated with its non-woven structure by irregular hatching.
  • Sealing membrane 1 and flame retardant membrane 2 are in the Broken open foreground of illustration; as a result, the insulating sheet 3 arranged on the remaining side of the flame retardant sheet 2 is then visible, which in turn has broken open again in order to make the trapezoidal sheet visible as a supporting part.
  • the insulation sheet 3 is shown dotted to indicate its porous structure. Not shown is a possible vapor barrier film between the insulation sheet 3 and the trapezoidal sheet 4.
  • the reference number 5 denotes a retaining tab which is held against the trapezoidal sheet by screws; ordinary sheet metal screws are particularly suitable as screws. This mechanical anchoring safely absorbs the wind loads and combustible parts under the flame retardant membrane are no longer required. The fire load is also reduced by saving on adhesive layers.
  • the roof covering shown in FIG. 2 can be brought onto the market in particular as a fully assembled roof covering element, that is to say as a multi-layer panel.
