    Title: FLI fire protection closure with cold smoke barrier BE2020/0020 Description In order to prevent the fire from spreading through the ventilation ducts, so-called FLI fire protection elements are installed. In the event of fire, the element foams up under the influence of heat and thus closes the cross-section of the ventilation pipe. However, the cold smoke gases that develop early on in a fire are also poisonous, which is why a so-called cold smoke barrier is also installed in the ventilation ducts in addition to the FLI fire protection element.
    DE 20 2004 003 276 U1 describes a cold smoke barrier which is connected to a fire protection valve via a heat-conductive holding frame. In this construction, the fire protection valve forms an element with the cold smoke barrier, the complexity of which becomes clear through the many exemplary embodiments in the manufacturing process.
    The innovation is therefore based on the task of further developing the combination of an FLI fire protection closure with a cold smoke barrier in such a way that a simple construction of the FLI fire protection element with a very low installation height is possible, which results in significant space savings with the same fire protection performance.
    The invention is characterized by the features of claim 1 in order to solve the task at hand.
    With the invention, the spread of cold fire smoke, flames and fire gases is prevented in the event of a fire. The simple construction and the resulting low installation height of the FLI fire barrier combine economical production with significant space savings in the ventilation duct. The protective function in the event of fire is independent of the direction in which it is inserted into the ventilation duct, so a safety-relevant source of error during installation is excluded.
    The advantageous embodiment of the invention is specified in claims 2-8.
    The invention is explained below with reference to FIG. 1 and FIG. It shows: Fig. 1 Construction of the FLI fire barrier.
    1 shows the structure of the FLI fire barrier 7. Here, an intumescent material 3, preferably an intumescent fabric, is fixed by two metal clips 2. The two metal brackets 2 are positioned at a 90° angle to one another. one metal clip 2 is placed over the top edge of the intumescent material 3 and the second clip 2 is placed over the bottom edge of the intumescent material 3 . In order to ensure an improved air flow, the metal brackets 2 are provided with multiple bores 4. The FLI fire barrier is provided with an external rubber seal, which enables convenient installation and safe positioning in the ventilation duct 6.

    Fig. 2 shows the cross-sectional view of the implementation of a combination of the FLI fire protection closure 7 with a cold smoke barrier 8 in a ventilation duct 6. The cold smoke barrier 8 is installed in the middle of the wall behind the FLI fire protection closure, the wall 5 can be a light partition wall up to a solid wall . The ventilation line 6 is a folded spiral pipe. The cold smoke barrier 8 has a low installation height in order to achieve maximum space savings. A cold smoke barrier 8 with a compressed air-sensitive membrane is preferably suitable here, which allows the gas flow to pass in the direction of flow but seals it smoke and airtight in the opposite direction.
    With the FLI fire protection closure 7 with cold smoke barrier 8 according to the invention, the spread of cold fire smoke, flames and fire gases is prevented in the event of a fire. Thanks to the ingenious design of the FLI fire protection barrier 7, a very low installation height is achieved, which fully guarantees the protective function in the event of a fire, regardless of the installation direction. This enables economical production and significant space savings in the ventilation duct. In addition, a user-friendly and optimal positioning of the FLI fire protection closure (7) in the ventilation duct (6) can be achieved through the metal clamps (2) running in the middle and the rubber seal on the outside.
