Definitions

  • the invention relates to fire protection glazing according to DIN 4102, consisting of a metallic, wood or silicate frame with associated glass retaining strips and at least one transparent, homogeneous, reinforced or composite pane, as single or multi-pane glazing, made of glass or glass ceramic, as well as associated organic and / or inorganic seals or covering tapes and with one placed in the edge region of the pane (s), at least on one side of the pane (s), between glass holding strip or a corresponding frame part and the pane (s), under the action of heat expanding means, possibly with a seal arranged between the disc (s) and this means.
  • a glass pane holder for fire-resistant doors in which between the holding strips a disk-receiving elastic holder is provided, which has grooves into which a fire-resistant foam developing mass is inserted.
  • This mass is arranged in the groove in such a way that it can expand as foam unhindered into the space between the washer and the seal and can even escape to the outside past the sealing lip.
  • This foam shields the elastic holder against the heat of the fire, but pressure is not built up at the edge of the pane to press on the pane, so that no higher fire resistance class is achieved.
  • DE-OS 31 42 846 discloses a frame system which can be used for such panes, in which a pressure-building means is arranged between the pane edge and the frame in such a way that the pane edge is bent in the event of a fire. Since the forces created by the design principle put so much pressure on the glass in the event of a fire that the combined effect of mechanical and thermal stresses means that the glass is likely to break, this glazing is e.g. unsuitable for float or borosilicate panes that must not break in the event of fire.
  • the object of this invention is therefore to develop a system for fire protection glazing, preferably for those with fire protection glasses that must not break in the event of a fire, which does not have the disadvantages mentioned above and which allows the installation of fire protection glass without increased contact pressure and only with a relatively small amount of glass in case of fire, preferably with a time delay, responds, then applies the necessary pressure and maintains it even over prolonged exposure to fire.
  • a strip of intumescent material 1 is housed in a suitably shaped profile 4, which puts the pressure on the disc 2 without deforming it.
  • the profile itself is held by a mounting screw 8 arranged in the center.
  • Sealing strip 5 from not combustible or flame-retardant material should preclude direct contact between glass and glass retaining strips7 and, after pressing on the glass retaining strip 7, also ensure that the pane is firmly seated even after assembly due to its elasticity.
  • rebate sealing profiles such as lip sealing profiles 18 made of flame-retardant neoprene, silicone or the like. with embedded intumescent strips 1 or with intumescent material contained in the seal itself leads to high fire resistance times (Fig. lb).
  • an additional profile can be dispensed with when a suitably shaped groove 20 is worked out in the holder 9; a one-sided arrangement of the intumescent strips 1 is also sufficient here.
  • the advantage of the invention over the conventional pressure is particularly clear: due to the expanding material, the pressure remains fully effective - even in the event of severe deformation or volume changes of the concrete due to the fire load. Fire resistance times> 100 min are achieved.
  • the block 3 is preferably made with flame-retardant building materials (for example Promatect).
  • the contact pressure can be further increased by using suitable auxiliary structures, as shown in FIG. 7, by means of a sheet 16, which is equipped with a mandrel and is stored in between.
  • a spring as a pressing means is described. Only in the event of a fire, after triggering the thermal fuse 10, e.g. Wood-Metall, the spring ll, which is located in a suitable guide system 12 with a movable piston 13, released to then generate the necessary contact pressure. In order to maintain the pressure even at elevated fire chamber temperatures, it is advisable to compensate for the ineffectiveness of the spring 11 by means of a reset lock 19 (FIG. 6).
  • a reset lock 19 FIG. 6
  • FIG. 3 shows a constructive solution for the use of a bimetal strip.
  • the strip 14 is accommodated in a suitable guide 12 in such a way that when it heats up and is deformed as a result, it applies the pressure to the glass pane 2 via a movable piston 13.
  • This system should preferably also be equipped with a reset lock 19, as shown in FIG. 6.
  • the guide system 12 which can be designed as an oval tube, has metal membrane walls 21 at its ends and thus forms a closed one System.
  • the energy content of the gas 15 enclosed in this system which can be air, for example, increases.
  • the necessary pressure is exerted on the surrounding area and thus on the fire protection window via the wall of the vessel.
  • This effect can be intensified if additional chemical agents, e.g. Na 2 CO 3 , CaSo 4 x 2 H 2 0, are also stored in the closed system, which when heated - by splitting off gaseous products such as C0 2 , H 2 0 etc. - contribute to increasing the pressure.
  • additional chemical agents e.g. Na 2 CO 3 , CaSo 4 x 2 H 2 0 are also stored in the closed system, which when heated - by splitting off gaseous products such as C0 2 , H 2 0 etc. - contribute to increasing the pressure.
  • Memory metals i.e. metals in which a certain structure is “frozen”, return to their original shape at elevated temperatures (e.g. Nitinol). If the type of installation is a "compressed” spring, then - at elevated temperatures - a spring force becomes effective which is sufficient to press the fire protection glass for longer fire resistance times.
  • FIG. 5 there is such a compressed spring 11 in a guide system 12, which exerts the corresponding pressure on the disc 2 in the event of fire via the piston 13.
  • This system too should preferably be equipped with a reset lock 19 (FIG. 6).
  • the pressure-building agent is supplied separately from the fire protection window 2 and is only combined with the fire protection window 2 directly or via seals 5 when the glazing is produced.
  • this procedure is time-consuming and costly; on the other hand, the frame of the glazing used may also have to be adapted to these special embodiments in order to ensure a component that is safe in terms of fire protection. It is therefore advantageous to fasten these pressure-building means in the case of such glazing in order to simplify assembly before installing the fire protection pane 2 at the edge of the latter.
  • FIG. 8 shows how the expanding agent, an intumescent building material 1, is attached to the edge of the pane 2 by means of a self-adhesive tape 22.
  • the supply tape 22 also serves as a seal.
  • FIG. 23 Another embodiment of the bracket 23 is shown in FIG.
  • the expanding means 1 is housed in a groove of the bracket 23.
  • the bracket 23 also serves as a holder for the seal 5.
  • the open side of the groove is closed by the seal 5 such that the expanding agent inserted into the groove cannot escape to the outside and can therefore exert pressure on the edge of the disk.
  • the other expanding means can also be attached to the edge of the pane by means of these attachment means before installation.
