Definitions

  • a wide variety of systems and element structures are known for fire protection of doors, flaps, housings or furniture.
  • the aim of these systems is to combine the non-combustibility of the objects with the longest possible fire resistance time with the most satisfactory mechanical properties of the objects.
  • the object of the present invention was therefore to create a method with which a fire-resistant component which is non-flammable, has a high fire resistance duration and can be used in construction can be produced.
  • this element is to be independently thermally controlled to compensate and remedy the weak points that arise.
  • the object is achieved in that an expandable fire-resistant fire protection cement is permanently connected to a molded part made of magnesium oxychloride foam.
  • the present invention therefore relates to a method for producing fire-resistant components, in which fire protection putty is applied to the points at risk of warping or cracking on a magnesium oxide chloride foam sheet.
  • the components constructed in this way also achieve their planned fire resistance duration if the overall structure is cracked or warped.
  • the heat passes through at any possible crack or insulation weak point in the components and activates the fire protection cement,
  • the inorganic magnesium oxychloride foam panel not only provides the desired fire resistance, but also has the necessary strength to be able to use the component as a composite element or core in the construction.
  • the magnesium oxychloride foam preferably contains finely divided glass fibers which even have a strengthening effect on the foam and counteracts the formation of cracks in the event of a fire.
  • the magnesium oxychloride foam is produced in a known manner by mixing magnesium chloride, magnesium oxide or fired magnesite, water, wetting agents and optionally additives this mixture by foaming agents, e.g. B. foamed hydrogen peroxide and optionally catalysts.
  • Foamable molding compositions based on intumescent agents which contain fillers are preferably used as fire protection putty, the fillers being spherical or almost spherical in shape and consisting of an inorganic material.
  • Intumescent agents are understood to mean those substances which form or foam at higher temperatures and produce a multicellular insulating foam.
  • the fire protection putty on the surface of the magnesium oxychloride foam plate, it can be provided with pins or knobs into which the fire protection putty is inserted or pressed.
  • the fire protection kit layers or locations can also be specified, if necessary in conjunction with a further construction element into which the magnesium oxychloride foam is then filled or injected in the liquid state as a core or layer or plate.
  • a profile made of fire protection putty (2) is injected around a magnesium oxychloride foam sheet (1).
  • the resulting fire protection element (l / 2) is flanged into the load-bearing sheet metal skin (3) and can also be glued to the surface (6).
  • the sheet metal skin has overlapping holes (4) in the rebate area through which the fire protection putty can escape in the event of a fire and seal against the frame (5) against fire and smoke.
  • the magnesium oxychloride foam plate (7) is coated on one or both sides with the fire protection putty (8).
  • the fire protection putty (9) can also be partially applied in different thicknesses.
  • a sheet of fire protection putty (11) is inserted between the magnesium oxychloride foam sheets (10), or the fire protection putty (12) is embedded in the magnesium oxychloride foam sheet (10) in such a way that it is only present at certain points and thus greater compressive strengths of the entire component are achieved.
