Definitions

  • Fire-retardant or fireproof doors with a variety of inserts such as. Mineral wool, plasterboard or asbestos-containing boards are known, e.g. from the approval of the IfBT, Z 6.13 - 117.
  • These door inserts are manufactured in a separate work step in partly complex procedures and then cut in further work steps and inserted into the frame construction of the door leaf
  • the object of the present invention was therefore to provide a method for producing a fire-resistant door construction element with which the door leaf can be manufactured in series in the desired shape and design with less material resources and meets the requirements with regard to the required fire resistance times.
  • a method for producing a fire-resistant door leaf which is characterized in that a mineral fiber layer is glued onto a thin sheet metal skin and then a magnesium oxide chloride foam layer is applied.
  • the mineral fiber layer can be a mesh, woven fabric, knitted fabric or mat made from a wide variety of inorganic constituents, e.g. B. glass wool, rock wool and / or asbestos fibers.
  • a glass fiber mat with a weight per unit area of approximately 250 g / m 2 is preferably used.
  • a water glass layer in which the glass fiber mat is embedded is preferably used as the refractory adhesive.
  • the amount of adhesive should be applied so that the glass fiber mat is not soaked, but mat parts remain dry.
  • the magnesium oxychloride foam applied is anchored in these still dry fiber parts.
  • the magnesium oxychloride foam is produced in a known manner by mixing magnesium chloride, magnesium oxide or fired magnesite, water, wetting agents and additives, and this mixture by foaming agents, e.g. B. hydrogen peroxide and optionally Catalysts foamed.
  • foaming agents e.g. B. hydrogen peroxide and optionally Catalysts foamed.
  • the sheet metal cladding is so well connected to the magnesium oxychloride foam layer that a considerable reduction in the sheet thickness, e.g. down to thin film thickness is possible, and additional bracing angles and screw connections as well as special profiles can be dispensed with.
  • the sheet metal cladding has only film thickness, it melts away in the event of a fire and there are no signs of distortion at all. This can e.g. B. are also deliberately caused by e.g. the sheet metal skin consists of aluminum or other light metals that are combustible or easily meltable.
  • two door cover layers with the structure described above are put together and connected to one another, so that fire protection is possible on both sides.
  • only one door cover layer can be applied to a door cover layer described above either with or without a water glass layer.
  • finely divided glass fiber is introduced into the magnesium oxide chloride foam, which has a so-called strengthening effect on the foam and prevents crack formation in the event of a fire.
  • the shape of the door is irrelevant for fire protection, but the magnesium oxychloride foam layer should be of sufficient thickness to have the required fire resistance time in the event of a fire.
  • a door panel (2) is already attached to the door frame construction (1). All fittings and tumblers (3) are also mounted. The inside of this door version (1, 2, 3) and the cover plate (4) are coated with adhesive (5). The glass mat (6) is placed in this adhesive layer. The edge (7) remains free of glue and glass mat.
  • the frame structure (1) is filled with liquid magnesium oxychloride foam (8). It is also advisable to impregnate the glass mat (6) on the cover plate (4) with magnesium oxychloride foam. Now the cover plate (4) is placed on the frame structure (1) and connected in the edge area (7) by screws, rivets or welding (9). The liquid magnesium oxychloride foam in the frame construction (1) and that on the cover plate (4) combine and form a unit after curing.
  • the frame structure (1) and the cover plate (4) are provided with adhesive (5) and glass mats (6).
  • adhesive (5) and glass mats (6) Without the magnesium oxychloride foam filling, the component is now fully assembled (screwed, riveted, welded) (9).
  • the liquid magnesium foam (8) is conveyed into the door cavity (10) by a sprue (12) by a pump or by a mixing and metering unit.
  • the frame structure (1/2) and the cover plate (4) are coated with adhesive (5) and glass mat. Now place a completely cut magnesium oxychloride foam plate or a magnesium oxychloride foam composite plate coated with water glass or magnesium oxychloride (13) into the door cavity. This construction is closed as in example 1 by placing the cover plate (4) and screwed, riveted or welded to the frame profile (1).
