Definitions

the present invention relates to a fire-resistant glazing comprising two panes assembled hermetically at their edges by means of a frame-shaped spacer, the interior space of this glazing being filled with a hydrogel containing a salt soluble in it. water.
Fire-resistant glazings of this technique are known for example from the documents DE-2 713 849 C2, DE-3 530 968 C2, EP-0 001 531 B1 and 0 049 204 B1.
the bracing frame is made of corrosion-resistant steel profiles, which are assembled by means of interlocking brackets also in corrosion-resistant steel.
the gel layer must be at least 15 mm thick to meet the conditions of fire resistance class F 30
the thickness of the glazing will therefore be worth at least about 25 mm.
glazings of the mentioned technique of a determined fire resistance class, but having a lesser total thickness.
such a requirement may be due to reasons of reduction in weight or because of a determined frame structure which limits the thickness of the glazing.
the object of the invention is to modify the structure of these known fire-resistant glazings in order to further increase the fire-retardant effect.
a firewall effect must be obtained that is as effective as that offered by known fire-resistant glazing with a total thickness of the glazing that is less.
bracing frame between the two panes is made of a heat resistant material, having a coefficient of thermal conductivity less than 2 kcal / mhK.
the invention is based on the fact that during fire resistance tests carried out on known glazing, the destruction of fire-resistant glazing generally begins at the edge. Obviously, the water vaporizes faster near the metal spacer than the rest of the glass surface. However, on the side of the glazing far from the fire, the area along the edge heats up faster than the central area and, as a result, it weakens faster than the center of the pane, which ultimately results 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 of spacers having a coefficient of thermal conductivity significantly lower than that of steel, and for the same thickness of the unit of glazing, the fire resistance time will be significantly increased. In this way, it is possible to achieve, with a significantly smaller thickness of the glazing unit, the same duration of fire resistance as known glazing.
heat resistant materials based on ceramic or silicate are used.
Such materials have a relatively low thermal conductivity coefficient, of the order of 0.5 to 1 kcal / mhK, while corrosion-resistant steel has a thermal conductivity coefficient of 15 to 45 kcal / mhK.
these materials have the particular advantage that they are insensitive to the aggressive salt solution present in the intermediate space of the glazing, so that the addition of particular anticorrosive substances, proposed in document DE-3 530 968 C2 even in case the use of corrosion resistant steel bracing frames is superfluous.
silicate glass in particular conventional float glass
the usual sealing system comprising an internal adhesive butyl sealing means, that is to say a copolymer of isobutylene and of isoprene, and an external adhesive thiocol sealing means, that is to say a thermoplastic polymer from the group of alkyl polysulphides.
adhesion promoter it is advantageous to improve the adhesion between the gel and the spacers by applying to them an adhesion promoter.
the primers described in particular in patent EP-B-0 001 531 are suitable.
adhesion promoters based on silane capable of reacting with the double or triple carbon bonds of the hydrogel or based on titanates or organic zirconates is recommended.
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 the lower thermal conduction in the context of bracing, no particular measure for thermal insulation must be taken at the window frame. 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 of the glazing by the frame, is not necessary. Glazing fire resistant designed according to the invention can therefore be installed in significantly narrower construction frames, which gives the fire resistant wall a lighter appearance.
Firebreak glazing generally has a rectangular shape like other glazing, so that the bracing frame consists of straight sections. However, it is obviously possible to manufacture fire-resistant glazing also in any other desired shape. So, for example, when glass is used as the material for the spacer, the glass strips can be bent into any desired shape after heating to their bending temperature, and thus, for example, fire-resistant glazing circular or semi-circular can be manufactured.
the drawing is a vertical section view of a fire-resistant glazing according to the invention.
the glazing comprises two panes of silicate glass 1, 2, each 5 mm thick and each made of thermally toughened float glass.
glass strips 3, 4, 5 are used, 12 mm wide, for example made of 4 mm thick float glass.
These glass strips 3, 4, 5 are bonded to the two panes 1, 2 by means of adhesive layers 6, 7 of butyl.
the groove between the glass strips 3, 4, 5 and the zones located along the edges of the panes 1, 2 is filled with a mass of adhesive sealing material 8 made of polysulphide.
the intermediate space formed in this way between the two panes 1, 2 is filled with a saline hydrogel 9.
a hole 10 is made in the strip of glass 5, near its lower end, or cut a corner.
a hole which serves as an orifice for venting is made in the opposite glass strip, which is not visible in the sectional view.
these holes which must first be kept free in an appropriate manner, by the introduction, for example, of short sections of tube into the holes, are tightly sealed after the polymerization of the gelling agent and after the removal of the sections of tube used for filling and venting, by placing the adhesive sealing material.
the bracing frame composed of the glass strips 3, 4, 5
particular corner pieces such as are used in the bracing frames made of sections of metal profiles, do not are not necessary, since the different glass strips are joined together.
a closed frame is first made from sections of interlocking sections and brackets and this frame as a whole is placed 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 a layer butyl adhesive. In this way, the closed bracing frame 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 carried out on fire-resistant glazing designed in this way.
the test of resistance to fire was made on a 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 the fire-resistant glazing was identical to the glazing fire barrier according to the invention. While the fire-resistant glazing comprising the bracing frame made of corrosion-resistant steel resisted fire for 25 minutes, the fire-resistant glazing according to the invention resisted fire for 32 minutes and therefore conforms to class. fire resistance F 30.
