Definitions

  • the present invention relates to glazing resistant to fire comprising two panes hermetically assembled to their edges via a frame-shaped spacer, the interior space of this glazing being filled with a hydrogel containing a water-soluble salt.
  • Fire resistant glazing of this technique is known for example from documents DE-2 713 849 C2, DE-3 530 968 C2, EP-0 001 531 B1 and 0 049 204 B1.
  • the frame bracing is made of steel profiles resistant to corrosion, which are assembled by means of brackets also in corrosion resistant steel.
  • the gel layer must be at least 15 mm thick to meet the requirements of the fire resistance class F 30.
  • the thickness of the glazing will therefore be worth at least about 25 mm.
  • glazing of the mentioned technique of a class of fire resistance determined, but with lower total thickness.
  • such a requirement may be due to reasons of weight loss or because of determined frame structure which limits the thickness of the glazing.
  • the invention aims to modify the structure of these known fire-resistant glazing in order to further increase the firewall effect.
  • we must obtain an effect firewall as efficient as that offered by glazing known firebreaks with total glazing thickness lower.
  • bracing frame between the two panes is made of heat resistant material, having a coefficient of thermal conductivity less than 2 kcal / mhK.
  • the invention is based on the fact that during tests of fire resistance carried out on known glazing, destruction fire-resistant glazing generally begins at the edge. Obviously, water vaporizes faster near the metal spacer than the rest of the glass surface. However, on the side of the glazing away from the fire, the area located along the edge heats up faster than the area central and thus weakens faster than the center of the glass, which ultimately results in the destruction of the glazing from its marginal zone.
  • the heating of the glazing in the marginal zone is greatly slowed down by the use spacers with a conductivity coefficient significantly lower than that of steel, and for a same thickness of the glazing unit, the resistance time fire will be significantly increased. In this way it is possible achieve with a significantly lower thickness of the unit glazing, the same fire resistance duration as known glazing.
  • heat-resistant materials based on ceramic or silicate.
  • Such materials have a coefficient of relatively low thermal conductivity, on the order of 0.5 to 1 kcal / mhK, while corrosion-resistant steel has a coefficient of thermal conductivity from 15 to 45 kcal / mhK.
  • these materials have the particular advantage that they are insensitive to aggressive salt solution present in the intermediate space of the glazing, so that the addition of specific anticorrosive substances, proposed in document DE-3 530 968 C2 even in the event use of steel bracing frames resistant to corrosion is superfluous.
  • silicate glass strips or profiles in particular usual float glass, have proven particularly suitable. If strips of silicate glass, it can in particular be stored without modifications to the usual sealing system with a internal butyl adhesive sealant, i.e. copolymer of isobutylene and isoprene, and a means sealing adhesive external in thiocol, i.e. a thermoplastic polymer from the group of alkyl polysulfides.
  • a butyl adhesive sealant i.e. copolymer of isobutylene and isoprene
  • a means sealing adhesive external in thiocol i.e. a thermoplastic polymer from the group of alkyl polysulfides.
  • the adhesive system When using another ceramic material or silicate than the usual float glass, the adhesive system must, if necessary, be adapted to this material.
  • Fire resistant glazing designed in accordance with the invention has, in addition to the favorable properties mentioned, the advantage that, thanks to thermal conduction lower in bracing, no measures particular for thermal insulation should only be taken at glazing frame level. This means for example that a relatively deeper mounting of the glazing in the frame, that is to say a significant overlap in the marginal zone glazing through the frame, is not necessary. Glazing fire resistant designed according to the invention can therefore be installed in construction frames clearly narrower, which gives the fire-resistant wall a lighter appearance.
  • Fire protection glazing generally has like other glazings a rectangular shape, such so the bracing frame is made up of sections straight. However, it is obviously possible to manufacture fireproof glazing also in any other desired shape. So, for example, when the glass is used as material for the spacer, glass strips can be folded into any shape after heating to their bending temperature, and thus, by example, circular or semi-circular firebreak glazing can be made.
  • the drawing is a vertical section view of a glazing fire barrier according to the invention.
  • the glazing comprises two silicate glass panes 1, 2, each 5 mm thick and each in tempered float glass thermally.
  • glass strips 3, 4, 5, 12 mm wide are used, for example in 4 mm thick float glass.
  • These glass strips 3, 4, 5 are glued to the two panes 1, 2 via butyl adhesive layers 6, 7.
  • the groove between the glass strips 3, 4, 5 and the areas along the edges glass 1, 2 is filled with a mass of material sealing tape 8 made of polysulfide. Space intermediate formed in this way between the two panes 1, 2 is filled with a salt hydrogel 9.
  • bracing frame composed of glass strips 3, 4, 5
  • corner pieces particular, as used in frames bracing made of sections of metal profiles do not are not necessary, since the different glass strips are joined together.
  • a frame closed is first made from sections of sections and interlocking brackets and this framework as a whole is installed on one of the two panes
  • the glass strips 3, 4, 5 are arranged separately one after the other on one of the two panes, after having been previously coated at least on one edge of an butyl adhesive layer. In this way, the frame of closed bracing is first assembled on the glass.
  • the fire resistance test in accordance with DIN 4102, part 2, paragraphs 6.1 to 6.2.5 was made on glazing firewall designed this way.
  • the test of resistance to fire was carried out on fire-resistant glazing in which the spacer, whose width was also 12 mm, was made of a corrosion-resistant steel profile, but the remaining structure of firebreak glazing was identical to fire-resistant glazing according to the invention. While the glazing fire barrier with steel bracing frame corrosion resistant fire resistant for 25 minutes, the fire-resistant glazing according to the invention has withstood the fire for 32 minutes and therefore conforms to the class of fire resistance F 30.
