Definitions

  • the invention relates to a fire-resistant glazing according to the preamble of claim 1.
  • the statutory fire protection regulations require fire protection barriers.
  • glazings in these parts of the building eg. B. as door or window glazing, they must also meet the fire safety regulations.
  • fire-resistant glazings that resist fire for at least some time.
  • These fire-resistant glazings are the subject of numerous, relevant industrial property rights based on the principle by using particularly heat-resistant transparent fire-resistant panes, eg. B. glass-ceramic or tempered glass and predetermined arrangements or brackets to achieve fire protection.
  • the term fire-resistant glazings therefore components and systems are understood, which consist of one or more translucent glass panels, which are installed with brackets and seals in a frame.
  • Fire-resistant glazing does not all have the same fire resistance. This is matched to the application and expressed in the relevant provisions by the so-called fire resistance class. With regard to their fire resistance classes, a distinction is made between EL, EW and E glazing. By specifying their fire resistance duration in minutes, they are additionally characterized (eg El 30, El 90, E 30). E-glazings prevent only the spread of fire and smoke for the appropriate time. EW glazing must also prevent the passage of heat radiation. In the case of El glazing, moreover, it is required that the increase in the glass surface temperature on the side facing away from the fire does not exceed a certain level.
  • Such known systems of fire-resistant glazing therefore consist of glass panes and filling layers in a sandwich construction, wherein the intumescent in case of fire filling layers either contain a certain amount of water and organic and / or inorganic compounds or mainly consist of water glass.
  • aqueous gels of water-soluble polymers such as.
  • acrylic polymers and water (Hydrogels) containing salts They are placed in relatively thick layers between hardened slices, the thermal protection effect being based on the controlled evaporation of water from the gel. This endothermic process leads to a cooling effect on the fire side away.
  • fire-resistant glazings and gel formers based on aluminum phosphate-amine salts are made EP 0 732 388 B1 Kunststoff. In case of fire, these gels expand to form ceramic rigid foams very strong and form thick insulation layers.
  • Widespread filling layers with organic additives from the group of polyhydric alcohols are also widely used on water-containing, amorphous alkali metal silicate, also called water glass.
  • water-containing, amorphous alkali metal silicate also called water glass.
  • the fireproof glazing is made by a laminar structure of lime / soda-float glass with intermediate filling layers of water glass, the alkali silicate.
  • the glass pane exposed to the heat shatters while the filling layer of the alkali silicate is inflated to a foam layer with evaporation of the water contained in it, which reduces the further heat transfer.
  • the intumescent water glass filling layers thus form a thermally insulating block of glass and inorganic foam.
  • the added polyhydric alcohols ensure the formation of an optimal, inorganic foam.
  • Fire-resistant glass together with the associated frames and fasteners form an architectural and functional unit. According to the progressive design requirements is since A trend towards the reduction of the frame area in the overall view of fire-resistant glazings is to be noted.
  • Such fire-resistant glazing for example, in the EP 0 498 021 B1 , of the DE 43 12 467 A1 and the EP 1 194 673 B1 described.
  • EP 0 498 021 B1 describes a solution in which the unsealed joints are each protected by a cover strip. In case of fire, the foam emerging laterally from the fireproof panel seals the joints thermally.
  • the DE 43 12 467 A1 describes a simple sealing of the joints with a non-flammable or self-extinguishing sealant, which thus already manages without any additional cover.
  • the solution according to the EP 1 194 673 B1 optionally works with an elastic seal or with a fixed insert, which fills the entire joint width between the fire protection glass.
  • the known seals are also to be evaluated as a compromise.
  • the fixed insert can indeed be chosen so that in case of fire, a good seal is granted. Due to the material properties of the insert (stiff and low elasticity), however, cavities inevitably form in the joints along the fire protection glass. These would cause corrosion in the fire-resistant glass embedded functional layers, since the lateral elastic seal forms only a small diffusion barrier. Therefore, an additional and complex protection of the functional layers in the form of a barrier material in the groove of each individual functional layer is required.
  • the invention is based on the object at the outset designated fire-resistant glazing with assembled butt joint construction fire doors effectively seal the joints of the fire-resistant glazing for everyday use, to protect the filler contained in the fire panels and to achieve especially in case of fire higher fire resistance times.
  • a fire-resistant glazing consisting of at least two held in a frame butt joint construction continuously joined fire protection and a seal in the butt joints according to the invention in that the seal is formed by a composite gasket of at least two functionally different components, and at least one Component the outer sides of the butt joints sealingly connects directly and without interruption with the inner sides of the fire protection windows.
  • the invention is based on the recognition that a composite gasket can be produced by the combination of properties of different materials, which meets the multivalent requirements for the joint seal far better than one-component materials, ie that meet the diverse demands on the joint seal only by a composite material are. Now it is well known that the combination of materials can result in composite materials with new properties. Obviously however, the use of such materials in the joint between fire protection glass fire-resistant glazing cause considerable difficulties in the glazing work and also increase the joint width unintentionally. In addition, when using expanding materials to get the premature displacement of the elastic-plastic material, resulting in a failure in the fire test.
  • the space closure of the joint is ensured over the entire time of the classified fire exposure.
  • the collapsed fire-resistant glass panels connect via the expanding seal to a plate and cause the space closure.
  • the processing is uncomplicated, the joint width can be kept small.
  • the fire-resistant glazing according to the invention thus also has the advantage of higher resistance in case of fire, with good suitability for daily use.
  • the material used as a binder-like material closes the joint and, once it has hardened to an elastic-plastic sealant, forms the spatial seal in everyday use.
  • strips / pieces of a strongly expanding material in case of fire are inserted.
  • the sole sealing function can not be taken over by this material because it is stiff, fragile and relatively difficult to process.
  • the insert of the highly expanding material can be done both centrally and off-center.
  • the impact of the fire-resistant glass can still be protected with a foil.
  • the elastic sealant In the event of a fire, the elastic sealant only initially ensures the space at the joint of the glazing. With increasing temperature, this substance softens according to experience, flows off, ashed or contracted. At this time, the seal is taken over by the now expanding into a stiff to firm foam expanding deposits. This foam practically connects the two adjacent fire-resistant glass panes to form a slab and thus ensures the room closure over the classification time.
  • joint widths of 3 to 15 mm can be realized, in a preferred embodiment, the joint width is 5 mm.
  • the linear arrangement of fire protection glass is to be regarded as standard.
  • the fire-resistant glasses can be arranged in the context of the invention at an angle between 45 ° and 180 °.
  • the fire-resistant glasses are arranged at an angle between 90 ° and 130 °.
  • the fire-resistant glasses are mitred at the abutting edge if the angle between the abutting disks is not 180 °.
  • Figures 1 and 2 show a first embodiment of the invention transparent fire-resistant glazing with a metal frame 1, with a U-profile within which in a vertical line orientation three fireproof glasses A, B, C, each of which the reference numeral 2 is assigned, are assembled in Stoßfugenbauweiseplan ,
  • the fire-resistant glasses used are preferably the fire-protection glasses available on the market under the brand name "Pyranova®" with the associated order details.
  • the width of the joints 3 between two fire protection windows 2 is 5 mm in the illustrated embodiment.
  • an inventively formed composite seal 4 is introduced, which in the illustrated embodiment of two deposits 5 each with the size 3 x 10 mm 2 , from a rigid, strongly expanding in heat material, eg the product with the order designation Palusol from the plastic " Plastics Plus "Family of BASF Aktiengesellschaft Global Business Unit Specialty Polymers & Specialty Foams, 67056 Ludwigshafen, embedded in an elastic-plastic sealant 6, eg a binder with the order designation Ottoseal® S. 94 or Novasil® S. 94 of the Fa. Herrmann Otto GmbH, Wettieri 14, 83413 Fridolfing.
  • This sealant is a neutral curing RTV-1 silicone sealant.
  • This fire-resistant glazing was tested according to the unfavorable regulation DIN EN 1363 and could be assigned to the fire resistance class El with the fire resistance duration 60 (EI 60).
  • FIGS. 3-5 show a further exemplary embodiment with a profile wooden frame 7 with the dimensions 78 ⁇ 40 in conjunction with two glazing beads 25 ⁇ 20, within which four fire protection panels A - D are likewise assigned the reference character 2 in a vertical line-shaped alignment is, in butt joints construction angled to each other.
  • FIG. 4 taken along the line I - I in Fig. 1, shows these bends, which, as indicated, in the range of 90 ° - 130 °, wherein according to Fig. 5 in the corner joints the fire protection discs 2 miter are cut.
