Definitions

  • the present invention relates to a mattress for fire protection, especially for applications as a firewall.
  • the term "mattress” is understood to mean an easily manipulable flexible device of substantially flat shape, in which the thickness is substantially less than or even less than at least a factor of 5, for example at least a factor of 10 to each of the others. dimensions.
  • such a mattress is substantially parallelepipedal.
  • this main surface is rectangular, but it can also be trapezoidal, have one or more curvatures, or have any shape adapted to protect a given device against the propagation of heat, especially in case of fires.
  • Such a mattress is for example used to protect cables and / or ducts in a cable duct or fluid passage means.
  • fluid passage means any channel or vector of a fluid in the broad sense, gas or liquid.
  • the cables or sheaths are generally containers of son or fibers such as for example electrical son of power or signal, coaxial son, optical fibers.
  • Such chambers are cavities allowing access to buried cable trays. They are for example distributed at regular distance over long distances to allow at first the drawing of the cables and subsequently their inspection.
  • the draw chambers are parallelepipedic, include a removable face and two faces adapted to the creation of openings may pass through cables, ducts or fluid passage means.
  • Such draw chambers are in particular installed buried in tunnels, and are substantially flush with the pavement level.
  • Safety requirements in tunnels are particularly high and there is a need to find enhanced fire protection means, especially for this type of application.
  • Mattresses for fire protection are known from the prior art, for example documents US 5,284,700 A and GB 2 424 260 A .
  • the present invention is a mattress for fire protection that can be handled easily while providing improved fire protection.
  • Such a mattress can indeed be manufactured on an industrial site and moved to be installed at a desired location. In addition, it can easily be removed, for example to inspect an installation or device it protects, and then be replaced without damage and while again ensuring excellent fire protection.
  • Such a succession of steps makes it possible advantageously to obtain a fire-protection mat having excellent fire-resistance properties and which advantageously delays an increase in temperature of a device or an installation that it is intended to protect. .
  • the present invention also relates to a draft chamber comprising walls, at least one wall is removable, defining a space for receiving cables and / or fluid passage means, generally passing through said draft chamber, which comprises a mattress for fire protection as described above or obtained according to the method above, and wherein said mattress is disposed between the space for receiving cables and / or fluid passage means and the removable wall.
  • Such a draft chamber is thus advantageously protected against a fire and can be installed satisfactorily in tunnels where it meets the safety requirements specific to such installations.

  • Each fibrous sub-assembly consists of three plies of wool of mineral fibers 2, 3, 4 superimposed and arranged parallel to said main surface of the mattress 1.
  • the mineral fiber wool plies are separated from each other, 4 and 3, 3 and 2, by at least one mineral fiber web. It is possible to have a single layer of fabric or to superpose several of them between two plies of mineral fiber wool.
  • Refractory particles 8 in particular metasilicates, are dispersed in a substantially homogeneous manner within each fibrous subassembly 11, 12, 13.
  • a means for obtaining a substantially homogeneous dispersion of the refractory particles 8 within each fibrous subassembly consists in arranging the refractory particles on the surface between two plies of mineral fiber wool, 4 and 3, 3 and 2, and then spiking. all.
  • the movement of the needles makes it possible to push these refractory particles and to ensure their dispersion within the layers of wool of mineral fibers, 2, 3, 4.
  • Refractory particles can also be disposed in contact with the fabrics 5 between the mineral fiber wool webs or between the fabric folds 5 if a plurality of mineral fiber fabrics are superimposed between the mineral fiber wool webs.
  • the fibrous subassemblies 11, 12, 13 are superimposed and joined together by a layer of refractory adhesive 6 disposed over substantially the entire contact surface between two fibrous assemblies, 11 and 12, 12 and 13.
  • An envelope 7 surrounds the assembly and forms the main surfaces of the mattress, as well as its side surfaces.
  • the casing 7 is made of mineral fibers impregnated with a flame retardant silicone.
  • this envelope is hermetic.
  • This envelope may comprise free ends extending beyond the main surfaces of the fibrous subassemblies, to ensure for example a connection between a wall and the mattress 1.
  • the mattress shown further comprises handles 10 disposed on a major surface of the casing 7 which allow easy handling of the mattress. It is thus possible to easily put it in place and if necessary to remove it, especially for an inspection after which the mattress is again put in place.

  • the drawing chamber 20 is substantially a rectangular parallelepiped of external dimension L x 1 x h. It comprises two substantially vertical walls 21, a bottom 23, a removable cover wall 24 and two side walls (not shown) comprising openings for passing a plurality of cables, sheaths, or fluid passage means 30.
  • such a side wall comprises zones of thinned thickness, in particular circular zones, which can easily be disengaged, for example with a hammer and a chisel, in order to provide an opening where it is desired to pass a cable and / or a sheath and / or a fluid passage means.
  • a bearing zone 22 has been formed in the walls 21 in order to receive and embed the lid 24.
  • the cables pass through the drawing chamber 20 and are electrical power cables, cables making it possible to connect sensors to a control system, installation control cables, coaxial cables, optical fibers. .
  • the walls 21, side, the bottom are usually concrete.
  • the lid 24 is for example made of reinforced concrete or cast iron.
  • such a draft chamber can be buried, and arranged for example so that the cover 24 is flush on a floor, especially at a roadway or sidewalk.
  • a mattress 1 for fire protection according to the invention is disposed between the cables, sheaths or fluid passage means 30 and the cover 24.
  • Said mattress 1 can be arranged directly and placed above the cables, sleeves or other means of fluid passage.
  • the grid 40 may be metallic and rest on supports, for example brackets 41 attached to the draft chamber and located between the cables, sleeves and other fluid passage means and the cover 24.
  • the mineral wool used consists essentially of silica (SiO 2 ), calcium oxide (CaO) and magnesia (MgO).
  • Each ply 2, 3, 4 of mineral fiber wool has a thickness of 7 to 8 mm.
  • each fibrous subassembly is about 25 mm, so that the total thickness of the mattress is about 75 mm.
  • the weight per unit area of each of the mineral wool sheets is about 6 to 7 kg / m 2 .
  • Metasilicate particles were arranged between the mineral fiber wool plies of each fibrous subassembly at a weight per unit area of 0.8 kg / m 2 . Each fibrous subset was then needled.
  • a refractory glue made of silico-aluminous component was placed between the fibrous subassemblies.
  • Mattresses thus produced have been arranged in a drawing chamber according to the representation in figure 2 .
  • Power cables, signal cables and optical fibers were arranged, and were connected on both sides of the draft chamber to measuring instruments.
  • the draft chamber thus constituted was placed in a furnace suitable for tests representative of a fire.
  • Refractory blocks made it possible to partition the lateral parts of the draft chamber while leaving the lid free. The whole was instrumented, in particular using thermocouples.
  • the first temperature cycle follows the normalized evolution according to the time-temperature curve referenced ISO 834, the second follows the evolution of a time-temperature curve known to those skilled in the art known as the HCM (for higher hydrocarbon) curve.
  • the mattress allows to obtain a non-degraded operation of power cables, signal and optical fibers arranged in the draw chamber for at least 4 hours for the tests according to the ISO 834 curve and for at least 2 hours for the tests according to the HCM curve.
