Definitions

  • the present invention relates to a fire protection structure, which uses a sound absorbing element, in addition to fire protection functions to take over acoustic functions, in particular to absorb room sound, in order to improve the room acoustics.
  • the sound absorber element is adapted in particular for installation in a wall or ceiling fire protection structure made of fire protection boards.
  • Such a fire protection structure is designed as a suspended ceiling construction or superior wall construction.
  • Preferred but not exclusive fields of application for the fire protection construction according to the invention are building construction, shipbuilding, industrial construction and tunneling.
  • Conventional fire protection structures are installed in different structures in order to increase the fire resistance of individual parts of the building, in particular to reduce the fire propagation speed.
  • fire protection plates made of non-combustible materials (so-called A1 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 room acoustics requirements are imposed, either additional acoustic elements must be installed, which significantly increases the production costs of buildings, or structural compromises are required that are at the expense of fire protection, for example if acoustic panels are installed on suspended ceilings which do not meet high fire protection requirements themselves.
  • the DE 34 44 881 C2 shows a sound-absorbingschreibwand- or ceiling structure of joint-bumped mineral fiber boards, which are connected to a supporting structure.
  • the mineral fiber boards are designed as prefabricated elements and have an adhesive layer on both sides.
  • the DE 93 21 610 U1 is an acoustic ceiling of sound-absorbing lightweight panels described.
  • the lightweight panels consist of interconnected by means of synthetic resin Blähglas-, Blähton- or similar particles.
  • the insulating body has a hovwerksporige structure, which is formed from expanded glass granules in a stable binder framework.
  • the DE 44 08 177 A1 shows a noise protection wall part, in which a wall element of solid concrete is provided on one side with an open-pore absorption layer.
  • the absorption layer contains mineral-silicate particulate material, in particular expanded clay or expandable slate.
  • a molded body made of a lightweight material known which has sound insulating properties is a liquid phase sintering of a mixture of a lightweight aggregate and a soda water glass takes place.
  • the lightweight aggregate used are expanded glass, perlite and / or expanded clay.
  • the lightweight aggregate particles are under formation of a Soda lime glass connected to this network. It is proposed to use the shaped body as an acoustic panel, in particular as a baffle, for which, however, no further instructions are given.
  • the DE 100 20 955 A1 shows a shaped body which is formed exclusively of sintered together lightweight aggregates selected from expanded glass granules, expanded clay granules or thermally pre-expanded perlites.
  • the object of the present invention is therefore to provide a fire protection structure made of fire protection panels for walls or ceilings of rooms, which can also take on acoustic tasks in addition to the actual fire protection function, in particular to absorb relevant sound components and thus to improve the room acoustics.
  • a fire protection structure according to the invention made of fire protection boards is particularly suitable for the arrangement on walls or ceilings of rooms.
  • the surface formed by the fire protection plates is interrupted along several lines. At these interruptions, a non-flammable, the fire protection requirements equally fulfilling, elongated sound absorber element is inserted between adjacent fire protection boards.
  • An absorption surface of the sound absorber element lies substantially in a plane with the surface of the fire protection plates facing the interior of the room.
  • the absorption surface is in the plane of the surface of the fire protection boards to give a closed visual impression and no unnecessary attack edges to provide for heat exposure.
  • a slight height offset (of, for example, 5% -10% of the thickness of the fire protection boards), but it obviously does not matter.
  • the sound absorber element used according to the invention is characterized on the one hand by the fact that it is suitable for easy installation in a wall or ceiling construction of fire protection boards.
  • it has an elongated carrier hollow profile, which has on two opposite longitudinal sides outwardly projecting attachment sections, which serve the attachment to each adjacent fire protection panels.
  • a longitudinally extending recess is provided, which opens into the inner cavity of the carrier hollow profile.
  • This recess can occupy the entire length and width of the front, so that the carrier hollow profile has a U-shaped cross section with laterally mounted attachment portions.
  • the recess extending at the front can alternatively be introduced as a groove or slot in a wall surface, so that narrow wall sections remain at the edges of the front side.
  • the sound absorber element further comprises an absorber strip of a sound-absorbing, non-combustible material which is fixed in the carrier hollow profile and has an absorption surface which is exposed in the plane of the recess of the carrier hollow profile and is not covered by fire protection plates even after the installation of the sound absorber element.
  • the attachment of the absorber strip takes place e.g. by clamping or gluing with a fire-resistant adhesive.
  • the absorber strip of the sound absorber element preferably consists of a glass-based, acoustically effective foam.
  • a glass-based, acoustically effective foam is a non-ductile mineral foam which may have high strength such as a stone, brick or concrete block processed in construction. Because it is a foam, there is a surface structure and, in the case of an advantageous design, a structure leaving a continuous airway, which in particular has an acoustically advantageous effect, namely in the sense of sound swallowing. Since at the same time a diffusion-open structure of the spacer is given, advantageous properties also result with regard to a removal of moisture, for example, from the space adjacent to the open absorption surface of the sound absorber element.
  • the carrier hollow profile is formed as a rail with a U-shaped cross-section.
  • the absorber strip then has a rectangular or square cross-section structure and corresponds in width to the fully open front of the profile.
  • the exposed absorption area is then the area which, when installed, faces outwards, i. is exposed to the acoustically influencing space.
  • the desired sound efficiency can be achieved particularly favorable by the foam.
  • the foam is replaced by another suitable sound absorbing material.
  • soft and possibly deformable materials such as rock wool or mineral wool can be used for sound absorption and form the absorber strip.
  • the carrier hollow profile is preferably made of metal, for example steel sheet. According to a preferred embodiment, the carrier hollow profile has inwardly directed holding elements which engage in the latter for fastening the absorber strip and / or exert clamping forces thereon.
  • the outwardly extending mounting portions of the carrier hollow profile are preferably formed as running on the opposite longitudinal sides of material strips, which are substantially perpendicular to the longitudinal sides.
  • the attachment portions may be made integral with the wall of the profile, or e.g. be secured by spot welding, rivets or the like.
  • the sound absorber element is preferably installed in the fire protection structure such that at least the absorption surface is exposed in the finished construction.
  • the absorption surface may also be covered by a further material layer, which is preferably acoustically highly permeable, for example in order to protect it against environmental influences or to enable an optical design.
  • the acoustically effective foam forming the absorber strip consists of glass parts or particles which are connected to one another by means of a binder.
  • the binder may be a hydraulic, also hydraulically setting binder. It is preferably a binder based on cement or ceramic. It is also expedient if the binder has a fiber content. Last but not least, such a fiber content can ensure the possibly desired diffusion openness or support it. Also, the fiber content contribute to the acoustic effectiveness.
  • the glass particles are preferably expanded glass granules which are compacted with the aid of the binder or else by a sintering process to form the acoustically effective foam.
  • the sound absorber element preferably has a rectangular or square, possibly also trapezoidal or triangular cross section.
  • Such a cross-section forms a flat absorption surface, which is integrated into the visible side or the outside of the fire protection structure to be acoustically influenced.
  • this absorption surface is not flat, but is characterized by the structure of the sound-absorbing material.
  • 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.
  • the absorption surface is initially covered by a self-adhesive film or similar protective layer.
  • This protective layer protects the absorbing surface from contamination during processing and can be removed after final completion of the fire protection construction.
  • the sound absorbing element is formed in the manner described above.
  • the fastening sections attached to the carrier hollow profile of the sound absorber element preferably rest on the rear side of the fire protection plates so that they are not visible from the interior of the room.
  • the position of the attachment portions is chosen so that the exposed absorption surface substantially in one Level with the surface of the fire protection boards, resulting in a closed surface of the wall or ceiling construction.
  • the thickness of the sound absorber element is selected, for example, such that it corresponds overall to the thickness of the fire protection boards, so that behind the fire protection boards no additional cavities for the installation of the sound absorber elements are needed.
  • the sound-absorbing 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 absorbing element is also clad on its longitudinal sides and its back with fire protection material.
  • the originally existing fire protection effect of the absorber strip in the sound absorber element is further enhanced. For particularly high fire protection requirements, this enclosure ensures a closed fire protection area.
  • 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 occupy about 15% to 30% of the total area of the fire protection structure. It has been found that the acoustic effect achievable with it is sufficiently high, by about 70% to 80% of the sound absorption a complete coverage of the available area with sound absorbing material can be achieved.
  • 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.
  • the glass-based acoustically-effective foam may be produced by conventional sintering techniques.
  • the hollow housing profiles can be easily produced by deep drawing or bending. A wall thickness of 1-3 mm is particularly preferred.
  • the carrier hollow sections can take on static tasks for the fire protection construction with a correspondingly stable design 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 e.g. glued.
  • Fig. 1 shows a cross-sectional view of a fire protection structure according to the invention.
  • the fire protection structure comprises a sound absorber element 1, to which fire protection plates 2 adjoin on both sides.
  • 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 panels 2 can be arranged in one layer (shown left of the sound absorber element) or in multiple layers (shown on the right of the sound absorber element).
  • the fire protection panels 2 are interrupted in their main extension plane to accommodate the sound absorbing element 1.
  • In a fire protection construction usually several parallel sound absorbing elements are arranged, for example at a distance of 30 to 70 cm.
  • 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.
  • the exposed surface of the absorber strip 6 forms an absorption surface 7, which is directed to the space to be acoustically influenced.
  • the absorption surface 7 is preferably in a plane with the surface of the adjacent fire protection panels. 2
  • the absorber strip 6 consists of an acoustically effective, namely sound-absorbing material in the manner of a foam.
  • it is a mineral material that forms a rigid foam.
  • the absorber strip 6 consists of glass-based, acoustically active and diffusion-open foam. Individual glass particles are connected by a binder, which may also have a fiber content, together to form a bar structure.
  • the edge length For example, the absorber strip 6 can be in the range of 2 to 8 cm.
  • a square cross-section is clearly chosen. Other cross-sections of the absorber strip 6 are also conceivable (eg triangular, oval, round) and may be advantageous for special applications due to their acoustic properties.
  • the length of the absorber strip 6 may be approximately in the range of 0.5 to 3 m. It is understandable to the person skilled in the art that the dimensions and the shape of the spacers can be adapted almost arbitrarily to the respective application. Decisive for the invention is that the absorber strip 6 consists of a material which has a good sound absorbing effect and at the same time has good fire protection properties.
  • the absorber strip 6 is fastened in the illustrated embodiment by means of two-sided punched and inwardly bent holding elements 10 in the carrier hollow profile 5. After insertion of the absorber strip 6, the holding elements 10 are pressed by the longitudinal sides of the carrier hollow profile inwards, so that they clamp the absorber strip 6 and / or partially penetrate into this.
  • the holding elements may be formed by pins, screws, rivets or the like, which engage through the wall of the carrier hollow profile in the absorber strip. It is also possible to glue the absorber strip in the profile or provide at the front of the carrier profile holding edges that prevent falling out of the absorber strip.
  • fire protection plates 11 can be attached to the back of the support hollow profile and optionally also on sections of the longitudinal sides.
  • fastening sections 12 are provided on the longitudinal sides, which are formed in the illustrated embodiment by elongated strips of material. With stable design of the carrier hollow profiles, these can assume a supporting function for the fire protection panels.
  • a lower fire protection plate 2 is arranged, for example, in a multi-layer structure, to which the fastening portions 12 of the sound absorber element can be screwed. Equivalent attachment methods are also possible.
  • the attachment portions 12 are positioned so that the sound absorber element projects beyond the lower fire protection plate 2, so that an upper fire protection plate can be applied, which also extends to the longitudinal sides of the support hollow profile and completely covers the attachment portions.
  • the surfaces of the upper fire protection plate and the absorption strip 6 then lie substantially in one plane.
  • the sound absorber elements can be connected in different ways with the fire protection panels.
  • the sound absorber elements can also be connected to other components, such as the supporting structure of the wall / ceiling.
