Definitions

  • the present invention relates to fire protection devices, in particular electrical cables for pipes or the like.
  • fire protection arrangements have been designed using dynamic elements such as flap systems, straps or systems for moving covers under the action of gravity or fusion of wedge elements.
  • French patent n ° 91 14 722 has also described a fire-break ventilation device with static elements which, for its part, has the drawback of a limited scope, which reduces its use for the protection of systems producing only 'a limited number of calories.
  • the aeration devices with static elements of the aforementioned type have large dimensions whose installation is not always possible.
  • the invention aims to remedy the drawbacks of known devices by creating a fire-resistant ventilation device which has an adaptable ventilation capacity. to the heat energy dissipated by the system to be protected, so as to obtain ventilation equivalent to that of an unprotected system.
  • a fire-resistant ventilation lining characterized in that it comprises a perforated tubular frame intended to be introduced into a ventilation opening in a wall of a space to be protected and in which are fixed opposite one another two plates of intumescent material with controlled expansion defining between them an aeration passage and ensuring the obturation of this passage as soon as the temperature at which the lining is found reaches a determined value.
  • the invention also relates to a fire ventilation device comprising at least one wall delimiting a space to be protected, said wall being coated with a thermal insulating material, characterized in that in said at least one wall is provided at minus one ventilation opening provided with a fire-resistant ventilation lining as defined above.
  • the fire-resistant ventilation lining shown in FIG. 1 mainly comprises an openwork tubular frame 1 formed in the present embodiment of two metal grids 2 and 3 arranged face to face and joined by plates 4,5 of refractory material.
  • the grids 2 and 3 have flanges 6 folded at a right angle by means of which they are fixed to the plates 4 of refractory material, for example using staples 7 arranged at regular intervals.
  • plates 10, 11 of intumescent material with controlled expansion which define between them an aeration passage 12.
  • the plates 10 and 11 of intumescent material are advantageously fixed to the plates 4 and 5 of refractory material by gluing.
  • the intumescent material with controlled expansion can be a silicone-based material. It is for example an intumescent material of type 335 S from the company MECATISS.
  • This material which can be in rigid or flexible form, does not release corrosive material such as halogens or sulfur.
  • the fire-resistant ventilation lining shown in FIG. 1 is produced in the form of a module or cartridge, of determined length, of 1 m for example. It can be cut on demand according to its length, to fill ventilation openings of shorter lengths or to complete the filling of ventilation openings requiring the juxtaposition of several ventilation fittings and whose length does not correspond to a whole number of such fittings. It is advantageously made in the factory.
  • the frame for receiving the intumescent material plates can also be produced using a perforated metallic tubular element such as for example a tubular grid of square or rectangular section.
  • FIG 2 there is shown in perspective, a fire ventilation device using fittings modular fire ventilation or cartridges, such as that shown in Figure 1.
  • This ventilation device comprises a sheet metal chute 15 formed by the assembly of a lower part 16 and an upper part 17, fixed to each other along a vertical lateral side of the chute by lugs 18 integral with the upper part 17 and cooperating with a folded flange 19 of the lower part 2.
  • the chute Along the vertical side wall opposite the legs 18 and the flange 19, the chute has a longitudinal slot 20 in front of which is disposed a fire-resistant ventilation lining 22 according to the invention, such as that described with reference to the figure 1.
  • the fire-resistant ventilation lining 22 which may consist of one or more cartridges of determined length juxtaposed, is fixed to a projecting flange 23 of the upper part 17 of the chute 15 for example by means of screws such as the screws 24 or even by means of staples similar to those which secure the grids 2 and 3 on the plates of refractory material 4 and 5 of the fire-resistant ventilation lining shown in FIG. 1.
  • the lining 22 is also fixed to the lower part 16 of the chute 15 by brackets 25 each provided with a hook 26 cooperating with a folded rim 27 of the vertical side wall opposite to that comprising the rim 19 cooperating with the lugs 18 of the upper part 17 and defining with the upper part 17, the ventilation slot 20 of the chute.
  • the chute 15 is surrounded by a cladding 28 of fire protection material.
  • thermal insulating material such as for example ceramic wool in superposed layers with interposition of glue between the layers and a covering of fabric of the same kind arranged on the external face of the external layer of ceramic wool.
  • the two parts 16 and 17 of the trough 15 are assembled on the one hand by the cooperation of the hooks 18 and the flange 19 and on the other hand, by the fixing of the fire-resistant ventilation lining 22 to the edges 23 of the upper part 17 and to the side wall of the lower part 16 of the trough via the fixing lugs 25.
  • the chute 15 provides the fire protection of the cables C which it contains while ensuring their ventilation under normal operating conditions by allowing the dissipation of the heat which they produce by the ventilation slot 20 of the chute which opens into the ventilation passage 12 formed between the plates 10, 11 of intumescent material of the fire-resistant ventilation lining 22.
  • the intumescent material of the plates 10 and 11 swells to cause the closure of the ventilation slot 20.
  • the swelling of the intumescent material is limited by the grids 2, 3 of the frame which confines its expansion in the volume which they define with the plates of refractory material.
  • a fire protection device which, while ensuring good ventilation of the systems which dissipate heat during their normal operation, ensures good protection against fire by closing the ventilation holes, provided in the walls of the protection device due to the swelling, both controlled and limited, of the intumescent material contained in the fire-resistant ventilation fittings fitted to the aeration devices.
  • such a device is particularly simple to install in so far as the modular fire-resistant ventilation linings according to the invention are in the form of cartridges, of determined length, which can be cut on demand. , depending on the length of the ventilation passage to be fitted with such a lining and the installation of which requires only simple screwing and / or stapling operations.
