Definitions

  • the present invention relates to devices for protection against fire, especially of electric cables of pipes or the like.
  • French patent n ° 91 14 722 (EP-A-0 544 600) has also been described fire-resistant ventilation fitting comprising an element of intumescent material controlled expansion ensuring the closure of an aeration passage as soon as the temperature at which the packing is reached reaches a determined value.
  • This trim has the disadvantage of a limited size, which reduces its use at protection of systems producing only a limited number of calories.
  • the devices ventilation with static elements of the aforementioned type have significant dimensions including the implementation space is not always possible.
  • the invention aims to remedy the drawbacks known devices by creating an aeration device fire barrier with adaptable ventilation capacity the heat energy dissipated by the system to be protected, so as to obtain ventilation equivalent to that an unprotected system.
  • an air lining fire-rated characterized in that it has a reinforcement openwork tubular intended to be introduced into a ventilation hole in a wall of a space to be protected and in which are fixed opposite each other two intumescent material plates with controlled expansion defining between them an air passage and ensuring the closure of this passage as soon as the temperature at which the trim is found reaches a determined value.
  • the invention also relates to a device fire ventilation system comprising at least one wall defining a space to be protected, said wall being coated with a thermal insulating material, characterized in that in said at least one wall is formed with at least one orifice ventilation provided with fire protection ventilation lining as defined above.
  • the fire-resistant ventilation trim shown in Figure 1 mainly comprises a tubular frame openwork 1 formed in this 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 edges 6 folded at an angle right 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 and 11 made of intumescent material are advantageously fixed to the plates 4 and 5 made of material refractory by bonding.
  • Intumescent material with controlled expansion may be a silicone-based material. It is by example of an intumescent material of type 335 S of the MECATISS company.
  • This material which can be in the form rigid or flexible, does not release corrosive material such than halogens or sulfur.
  • the fire-resistant ventilation trim shown in Figure 1 is made 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 with shorter lengths or to complete the orifice filling ventilation requiring the juxtaposition of several ventilation fittings, the length of which does not correspond not to a whole number of such fittings. She is advantageously made in the factory.
  • the frame for receiving the material plates intumescent can also be performed using a openwork 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 system using fittings modular fire ventilation or cartridges, such than that shown in Figure 1.
  • This ventilation device includes a chute in sheet metal 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 edge 19 of the lower part 2.
  • the chute has a longitudinal slot 20 in front of which is arranged a fire-resistant ventilation lining 22 according to the invention, such as that described with reference to FIG. 1.
  • the fire-resistant ventilation lining 22 which can consist of one or more cartridges of determined length juxtaposed, is fixed to a ledge protruding 23 from the upper part 17 of the chute 15 for example by means of screws such as screw 24 or else by means of staples similar to those which ensure the fixing grids 2 and 3 to the material plates fireproof refractory lining 4 and 5 shown in Figure 1.
  • the lining 22 is also fixed to the part lower 16 of the trunking 15 by brackets 25 each provided with a hook 26 cooperating with a flange folded 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 than for example ceramic wool in superimposed layers with interposition of glue between the layers and a covering of fabric of the same kind arranged on the face outer layer of ceramic wool.
  • the chute 15 provides fire protection for cables C that it contains while ensuring their ventilation under conditions normal operation by allowing dissipation of the heat they produce through the ventilation slit 20 of the chute which opens into the passage ventilation 12 formed between the plates 10,11 of material intumescent of the fire damper 22.
  • the intumescent material of the plates 10 and 11 swells to cause the obturation of the ventilation slot 20. Swelling of the intumescent material is limited by the grids 2.3 of the frame which confines its expansion in the volume they define with refractory material plates.
  • such a device is particularly simple to set up since the modular fire protection ventilation fittings according to the invention are in the form of cartridges, length determined, which can be cut on demand, in depending on the length of the ventilation passage to be fitted of such a packing and whose installation does not require than simple screwing and / or stapling operations.
