Definitions
- 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 water.
- fire protection membranes are attached to roof structures and membranes that are not "hard roofing” in the sense of DIN 4102 and are therefore not resistant to flight fire and radiant heat. With these fire protection membranes you can achieve the desired "hard roofing”.
- the fire protection sheets are inserted between the insulation material and a top layer. They are mainly used for plastic films or high polymer webs. An example of a "hard roof” achieved in this way is described in DE-OS 3,220,821.
- EPS means expanded polystyrene.
- Poly styrene is a thermoplastic.
- this synthetic foam is the ideal solution.
- thermoplastics laid as insulation on steel profile sheets behave particularly favorably in the initial phase of a fire.
- they sinter or melt and absorb heat.
- the transfer of heat to the steel profile sheet is delayed. It is said that the temperature flows upwards. If the fire continues, however, the roof skin is subjected to greater stress. After the insulating material has burned away or disappeared, the temperature breaks down. If the fire lasts longer, the surface may burn through.
- a melting thermoplastic or a non-melting material was used as the insulating material.
- 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 sheet should be equipped so that in the event of a fire, burn-through from below until the steel profile sheet collapses is reliably prevented.
- the solution to this problem according to the invention results from the fact that the load-bearing sheet is an aluminum foil, plastic foils are laminated onto both sides of the aluminum foil and have a content of crystalline water ⁇ pointing glass fiber fleece is laminated onto one of the plastic films and coated on its free surface with a wax layer.
- the glass fiber fleece, which contains the crystal-bound water, is designed, for example, according to DE-OS 3 220 821.
- This fire protection membrane with vapor barrier according to the invention is laid over the load-bearing roof structure, for example the steel profile sheet, and under the insulation membrane.
- 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 flushed out during laying on the construction site. With this feature, sufficient moisture security is achieved for the laying time on the construction site.
- the fire protection membrane according to the invention can and should be covered with additional membranes immediately after it has been laid.
- the plastic film coated on the underside of the aluminum film is expediently made of polyester, while the plastic film laminated on the upper side consists of polyethylene.
- the fire protection sheet according to the invention When the fire protection sheet according to the invention is laid on a profiled sheet, the profile spaces which are then left free can be partitioned off.
- rods or cubes made of plastic foam can be inserted around them. These bars or cubes close the profiles or beads of the profile sheet. This prevents combustible gases, smoke and the like from continuing to flow and spread.
- the rods or cubes consisting of a plastic foam are expediently impregnated 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. What is new, however, is the use of these cubes or rods 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 profile cavities can also be sealed off with sand or gravel. This is simply poured into the profile cavities.
- the branch protection sheet according to the invention has a high tear resistance. It can therefore be laid on steel profile sheets or steel trapezoidal 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. In the case of 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. In the event of a fire from below, the fire protection sheet on top releases about 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.
- the fire protection sheet according to the invention can, as stated, be laid directly on steel profile sheets, such as trapezoidal steel sheets. It can also be placed on other substructures in need of fire protection. It forms the vapor barrier necessary for building physics reasons and, at the same time, prevents burnout, as stated.
- FIG. 1 is a perspective view, not to scale, of the fire protection sheet, the sheets being drawn broken for better understanding,
- Fig. 2 on a different scale, a perspective view of the steel trapezoidal sheet used with inserted rods made of plastic foam and
- FIG. 3 shows a representation corresponding to FIG. 2 with sand poured in. Description of an embodiment
- Fig. 1 shows the steel profile sheet 12, which is a trapezoidal sheet.
- the fire protection membrane according to the invention lies on this. This includes the aluminum foil 14 and the plastic foils 16 and 18 laminated on both sides thereof.
- the glass fiber fleece 20 is laminated onto the plastic foil 16 lying on top. This is treated with a fire protection agent and / or enriched with crystalline water.
- the cavities or beads of the trapezoidal sheet 12 are designated by 24.
- cubes or rods 26 made of plastic foam lie in these beads.
- These rods can also be treated with a fire protection agent or contain crystalline water. As stated, they prevent smoke and combustible gas from flowing through the beads 24 in the event of a fire and thus being distributed in the building and the roof structure. 3, small piles 28 of gravel or sand are filled into the beads.
