- fire protection plates made of non-combustible materials (so-called AI materials) are attached.
- Conventional fire protection boards only to a limited extent take on static functions (for example in the construction of lightweight walls) and usually show no desirable acoustic properties. If special demands are made on the room acoustics, either additional acoustic elements are required, which increases the manufacturing costs of buildings significantly, or are planning compro ⁇ mise required to be borne by the fire protection, for example if reasonable to suspended ceilings acoustic panels which do not meet high fire protection requirements themselves.

- the absorption surface, which forms the visible side or is integrated into the outside of a concrete pavement is also that surface which is not covered or only along its edges by the material of the carrier hollow profile. It is particularly advantageous if the absorption surface is initially covered by a self-adhesive film or similar protective ⁇ layer. This protective layer protects the Absorp ⁇ tion surface during processing from contamination and can be removed after final completion of the fire protection construction.
- the sound absorber element is formed in the above beschrie ⁇ surrounded manner.

- the sound absorber element may for example have a thickness of about 25 mm.
- the fastening sections of the sound absorber element can also be used between the individual layers, whereby the assembly is facilitated.
- a preferred embodiment of the fire protection structure is characterized in that the carrier hollow profile of the sound absorber element is also clad with fire protection material on its longitudinal sides and its rear side.
- the originally existing fire protection effect of the absorber strip in the sound absorber element is further enhanced.
- a closed fire protection surface is ensured by this covering.
- the dimensions of the individual sound absorber elements and their spacing when installed in the fire protection structure are preferably chosen so that the exposed absorption surfaces of the sound absorber elements about 15% to 30% of
- the acoustically effective absorption surfaces can be painted or coated with an open-pored plaster. It must be ensured that a coating remains acoustically permeable so that the sound-absorbing properties are retained.
- Different methods are suitable for the production of the sound absorption element.
- the glass-based acoustically effective foam can be produced by conventional sintering ⁇ method.
- the hollow housing profiles can be easily produced by deep drawing or bending. A wall thickness of 1-3 mm is particularly preferred.
- the Rushhohlpro ⁇ file can take stably ⁇ stati ⁇ cal tasks for the fire protection construction and replace, for example, the usual ceiling slab rails or the stand of lightweight walls.
- the absorber strip is mechanically fastened in the profile or, for example glued.

- the fire protection panels 2 are in conventionally attached to a stand construction, to suspended mounting rails or other stabilizing the wall or ceiling structure components.
- the fire protection plates 2 can be arranged in a single layer (shown to the left of the sound absorber element) or in a multi-layered arrangement (shown to the right of the sound absorption element).
- the fire protection panels 2 are interrupted in their main extension plane to accommodate the sound absorbing element 1.
- a plurality of parallel sound absorber elements are usually arranged, for example at a distance of 30 to 70 cm each.
- the sound absorber element 1 has a carrier hollow profile 5, in whose cavity an absorber strip 6 is arranged.
- the carrier hollow profile 5 is formed by a U-shaped sheet metal rail, which has two longitudinal sides and a rear side.
- the front of the carrier hollow profile is open, so that the absorber strip 6 is exposed at this front.
