Definitions

  • the present invention relates to a frame for mounting a shutter in a ventilation system including smoke extraction.
  • Aeraulic smoke extraction systems generally consist of air ducts which are arranged in traffic areas for the purpose, during a fire, to secure the evacuation of people by sucking smoke to the outside. To do this, these ducts are equipped with one or more flaps which, in the open position allow smoke suction and in the closed position prevent heat loss. Fixing this or these shutters is usually performed through a frame that is positioned between the frame of the shutter and the air duct.
  • the mounting of a shutter in a ventilation system is generally made from a rectangular L-shaped section which is placed between the frame of the shutter and the periphery of the air duct. .
  • a protective grid is mounted by means of an additional frame which takes, for aesthetic reasons, the shape of a profile.
  • the assembly-mounting frame assembly can receive the installation of different grids.
  • current legislation in France and in Europe notably the NF-S-61937 standard, requires the grid-shutter assembly to obtain certification.
  • Such a modular configuration can therefore cause a grid / shutter combination not provided by the manufacturer and therefore not certified, which could therefore greatly affect the safety of the installation.
  • the frames generally used for the mounting of the shutter do not allow the installation of air intakes necessary for the establishment of measuring devices for the qualification grid / shutter.
  • the document FR 2,286,351 relates to an air passage opening having fins for adjusting the air passage section, coated with a fire-resistant stiffening material.
  • the present invention aims to remedy these disadvantages.
  • the invention relates to a frame for mounting a shutter in a ventilation system, including smoke extraction, characterized in that it comprises a first rear portion which, intended to be inserted into an opening opening into a duct aerodynamic, has a hollow portion comprising a cavity open at the rear containing elements of refractory material and a profiled second portion which, intended to come into application against the wall in which is formed the aforementioned opening, is equipped with means for fixing a protective grid.
  • the device makes it possible, by integrating the attachment of the grid to the mounting frame of the shutter, to make the grid-shutter assembly integral thus avoiding any error in mounting an inappropriate grid during the installation, which could contravene to secure the area to be protected.
  • the hollow part of the frame comprises a closed cavity disposed in front of the open cavity.
  • the closed cavity makes it possible to create a space between the opening of the duct and the flap, thus limiting, during a fire, the heat transfers to the shutter and therefore the malfunctions that could result.
  • This hollow part also offers cable routing possibilities for the installation of potential sensors or to allow motorization of the shutter.
  • the elements of refractory material protrude rearwardly with respect to the cavity in which they are engaged.
  • the refractory elements are equipped with hinge elements of the flap.
  • Such a material offers good resistance of the elements to the flames thus ensuring the smooth operation of the flap in the extreme conditions that may prevail during a fire.
  • the front part of the frame has a wing inclined from the inside to the outside and from the front to the rear, the outer part of the wing being intended to come into application against the wall in which is formed the opening of the air duct and the inner part of the wing being intended to receive the protective grid.
  • Such a configuration of the mounting frame makes it possible to associate the cladding function of the wall with the function of maintaining the grid, thus ensuring a better integration of the device in the zone to be protected.
  • the protective grid is fixed to the frame by snapping.
  • This fastening means allows rapid mounting of the protective grid.
  • the closed cavity has at least one orifice turned towards the inside of the frame and at least one orifice turned towards the outside and forming a pressure tap intended to be connected to at least one apparatus of pressure measurements.
  • Such openings allow the installation of the necessary measuring devices in view of the qualification of an installation comprising a mounting frame identical to those used on site, thus allowing certification of an installation with characteristics identical to those of a final installation.
  • the frame is made from extruded aluminum profiles assembled by brackets.
  • the elements of refractory material are coated respectively on the side of the wall defining the opening and on the flap side, intumescent material strips.
  • intumescent material make it possible to ensure the tightness of the duct for a closed position of the shutter, thus making it possible, during a localized fire, to limit the suction losses at the levels of the openings of the duct present on areas not concerned. . They also make it possible to reduce thermal losses linked to an installation that is not dedicated to cleaning the air.
  • the intumescent character during a rise in temperature related to a fire in the area protected by the conduit, causes swelling of the strips thus improving the seal at the frame and thus limiting the transmission of fire and heat .
  • the figure 1 represents an installation comprising a smoke exhaust duct equipped with a frame 1 according to the invention.
  • This frame 1 is used for mounting a shutter 2 in an opening of a ventilation duct 3, made in a wall 4.
  • a fitting part 5 made of refractory material makes it possible to make the assembly of the frame of the shutter 6 compatible with the opening 3, the dimensions of which may vary.
  • On this adaptation piece is fixed a support frame called counter-frame 7 having a section L-shaped.
  • the frame 1 for mounting the shutter 3 according to the invention is mounted on this counter frame 7.
  • This frame 1 of generally rectangular shape, comprises a rear portion formed by a substantially rectangular hollow wall and a profiled front portion intended to be applied against the wall 4. It comprises, as illustrated in FIG. figure 2 at the rear, a first cavity 8 open, towards the rear, which forms a substantially rectangular cavity in which, as illustrated in FIG. figure 1 , housing elements 6 made of refractory material forming the frame of the shutter 2.
  • the frame 1 also comprises, in the extension of the first cavity 8 and in front of the latter, a second cavity 9 which is closed and which allows The cavity 9 forms a chamber communicating with the outside through orifices 10a turned towards the inside of the frame and through an orifice pressure intended to be connected to pressure measuring devices.
  • the cavity 9 can also be used for cable passages for possible sensors or the motorization of the shutter 2.
  • the frame At its outer end, the frame comprises a flange 11 which has an inclination from the inside to the outside and the front to rear and is positioned in abutment against the wall 4.
  • the frame 1 Inwardly and in the extension of the wing 11, the frame 1 comprises a cavity 12 for snap-fitting a protective grid 13 shown on the figure 1 . This assembly is done by means of the rods 14 of the protective grid 13 which snap into the cavity 12.
  • the frame 1 itself consists of four sections 15, as illustrated in FIG. figure 3 . These profiles extend along a longitudinal axis and have at their ends beveled edges at an angle of ⁇ of 45 ° with the longitudinal axis.
  • the frame-like mounting of these sections 15 is achieved by the use of angled pieces which are housed in grooves 16 present on the inside of the outer flange 11 of the frame 1.
  • the frame of the flap 5 for ensure the watertightness of the installation, as shown on the figure 1 strips of intumescent materials 17 acting as joints. These strips 17 are respectively located, to ensure the tightness of the duct 3, between the frame of the flap 6 and the adapter part 5, and, to ensure the tightness of the flap 2, between the frame of the flap 6 and the flap 2 himself.
  • the frame of the shutter 6 also comprises a hinge 18 on which the shutter 2 is fixed, which allows the latter to pivot about the axis 19 between a closed position, illustrated on the figure 1 and an open position, not shown.
  • the installation uses the following principle to secure a traffic zone.
  • the flap 2 In the absence of fire in the area to be protected, the flap 2 is in the closed position.
  • the duct 3, by the combination of the flap and strips of intumescent material 17, does not communicate with the aforementioned area.
  • This closing of the duct also makes it possible to limit the thermal leaks.
  • the flap 2 pivots to the open position, thus releasing the suction corridor formed by the duct 3, which creates a continuous evacuation of the smoke.
  • the zone being smoke-free, is secured to allow evacuation of people.
  • the invention is not limited to the embodiment described above. It may in particular be implemented with a frame formed from welded steel profiles, be installed on ventilation air ducts this by implementing, for example, a flap frame non-refractory material or be implemented on a fire damper, the flap being, in this configuration, put in closed position during a fire.
