Definitions

  • the invention relates to a tape protection sheet, in particular for covering Dacb.
  • Such sealing sheets are usually plastic films or bituminous sealing or roofing sheets, which are also referred to as "roofing felt", for example. But it is precisely for these geomembranes that insulating materials result in the dangerous wicking effect during the fire.
  • materials of fire class A according to DIN 41 0 2 such as perlite, mineral fibers or foam glass, cannot always be used as insulation materials.
  • insulation materials of fire class B according to DIN 41 o2. These insulation materials are intended to ensure temperature insulation, especially, of course, if there is no fire. All this applies in particular to roof coverings, as are common today in large-scale commercial buildings, for example for supermarkets.
  • the most important of these is the fulfillment of the latter requirement, ie to effectively prevent progressive fire events; but it has not yet been resolved either.
  • the invention is therefore particularly based on the task of eliminating the risk of burn-through and progressive fire events such as a widespread conflagration.
  • a fire protection membrane which consists of a sealing membrane of a known type, for example of the type mentioned above, on the at least one side of which an additional flame protection membrane is arranged.
  • a fire protection membrane which consists of a sealing membrane of a known type, for example of the type mentioned above, on the at least one side of which an additional flame protection membrane is arranged.
  • it is a two-layer fire protection membrane, consisting of a sealing membrane and a flame protection membrane.
  • the type of flame retardant membrane is essential.
  • such a flame retardant membrane is understood to be one which releases an incombustible liquid, such as water, in vapor form at elevated temperature; it can also separate fire-emitting gases such as nitrogen.
  • a fiberglass fleece impregnated with water glass, for example, is particularly suitable as a flame retardant membrane in the sense of the invention.
  • a fire protection membrane of this type is known, for example, from DE-OS 29 6o 796.
  • Fire protection membranes based on glass fiber fleece are generally suitable, in which crystalline water is embedded.
  • diatomaceous earth saturated with water can also be used as the base material for the flame retardant membrane.
  • Such water-containing substances only release their loosely bound water at around 100 ° C; there sometimes they foam up additionally.
  • water-containing ammonium phosphates as the base material for the flame-retardant membrane
  • fire-emitting gases for example nitrogen
  • DE-OS 28 07 697 called 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-PS 962 824, DE-AS 10 61 011, DE-PS 10 65 116, DE-OS 16 44 780, DE-OS 17 94 343 and DE -OS 22 00 104. According to this state of the art it is also known to apply these substance compositions in pasty form to glass silk fabric or nonwovens; this results in flame retardant strips.
  • 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 with the flame retardant membrane on the top of the roof covering.
  • 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 sheet has an additional heat in case of fire insulation 'between the flame path to the sealing sheet and the other free side of the insulation sheet, which is the roof side 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 was held at a distance of approx. 25 cm from above onto the cover film, i.e. the sealing membrane.
  • the outer cover film i.e. the sealing membrane
  • the insulating material i.e. the insulation sheet
  • the burn spot size was a maximum of 58 cm in diameter for all superstructures. While the temperatures in the firing center reached values in the range of 1000 ° 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 3o 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 shows a perspective view of an element of the fire protection membrane according to the invention.
  • the sealing membrane is identified by reference number 1. She's broken her face in a part to make s o the area of the flame retardant web 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 elegant quality of water glass has 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 broken open in the foreground of the figure; as a result, the insulation 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. In addition, the fire load is 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.
