Definitions

  • the present invention relates to a smoke evacuation flap to be installed in a smoke exhaust duct, comprising at least one leaf which is mounted in the frame and which, once installed, can move in the smoke extraction duct between a closed position, in which the duct is closed, and an open position, in which the duct is open, and which comprises a refractory material plate which extends essentially over the entire surface of the leaf.
  • a smoke evacuation component is known in particular from the FR-A-2242845 . Flaps of this type are normally part of a flue gas and heat system. Flaps are normally mounted on a wall or ceiling. These evacuation systems are mainly intended for the mechanical smoke extraction of buildings in order to facilitate the evacuation of people.
  • a smoke evacuation flap of this type is normally closed and fire resistant when in the closed position.
  • the shutter is open only in case of fire so as to allow a controlled evacuation of fumes.
  • the shutter then opens in the smoke extraction duct.
  • a control system only opens the flaps necessary to ensure a smoke evacuation.
  • Other shutters which can not contribute to the desired evacuation, remain closed and must withstand fire.
  • the object of the invention is therefore to provide a smoke evacuation flap which, when in its closed position, has a better seal to cold air and hot air compared to existing flaps.
  • a smoke-evacuation flap door comprising a frame for installing the flap in a smoke exhaust duct, comprising at least one leaf which is mounted in the frame and which, once installed, can move in the smoke exhaust duct between a closed position, in which the duct is closed, and an open position, in which the duct is open, and which comprises a refractory material plate which extends essentially over the entire surface of the leaf
  • the frame has aluminum profiles for fixing the shutter in the conduit, the shutter comprising one or more seal (s) which, when the leaf is in the closed position, is (are) positioned between the aluminum profiles of the frame and the leaf, so as to ensure airtightness of the shutter when the latter is in this closed position, the frame comprising refractory material and the side of the smoke exhaust duct, the aluminum profiles of the frame are shielded by said refractory material of the frame.
  • a seal of this type may for example be made of rubber or silicone.
  • the profiles may for example have grooves in which the seals can be introduced, as is well known for aluminum profiles for doors and windows.
  • the leaf can be mounted in the frame using one or more hinges (s). The leaf can then rotate in the duct.
  • a leaf that can move in the duct itself has the advantage that, after opening, the leaf does not constitute an obstacle in the areas through which people must be evacuated, unlike leaves that open. towards the outside of the duct.
  • a shutter may comprise a leaf, but may also include a plurality of leaves.
  • said plate of refractory material of the leaf extends essentially on the outside of the leaf.
  • the leaf preferably comprises aluminum profiles which extend essentially over the contour of said refractory material plate and the joints are preferably positioned between the aluminum profiles of the frame and the aluminum profiles of the leaf.
  • the aluminum profiles of the leaf are preferably shielded by said plate of refractory material of the leaf.
  • said refractory material plate is a calcium silicate plate.
  • This calcium silicate plate can be self-claved and can optionally be reinforced with fibers.
  • the aluminum profiles of a shutter according to the invention are preferably extruded profiles.
  • the leaf comprises a second refractory material plate which extends essentially over the entire surface of the leaf, so as to form a flap which is even more resistant to fire.
  • This second plate of refractory material is preferably positioned at a distance from said first plate of refractory material, so that the plates and the aluminum profiles of the leaf define an interior vacuum in the leaf.
  • Such a vacuum forms an insulating barrier, which promotes firewall performance and further decreases unwanted heat loss.
  • the aluminum profiles of the leaf are preferably positioned substantially between said first plate and said second plate.
  • this mechanism is preferably arranged substantially between said first plate and said second plate, so that this mechanism is not accessible from the outside when the shutter is in the closed position.
  • Said second refractory material plate is for example a plasterboard.
  • a plasterboard of this type may optionally be reinforced by glass fibers.
  • the flap comprises at least one bar which is mounted in the frame so as to form an obstacle in the smoke evacuation duct when the leaf is in the open position.
  • this obstacle prevents objects or people from falling into the duct.
  • one or more bar (s) is (are) provided in the frame, forming a grid which constitutes an obstacle in the conduit.
  • the leaf preferably comprises at least one groove in which said bar is housed when the leaf is in the closed position.
  • the flap comprises one or more intumescent gasket (s) surrounding (n) at least partially said first plate of refractory material.
  • a shutter according to the invention further comprises one or more intumescent gasket (s) surrounding (s) at least partially the frame.
  • the figures show a gate (1) for smoke extraction to be installed in a smoke extraction duct (2).
  • the shutter (1) is mounted on a wall or ceiling (16).
  • the shutter (1) is normally closed, as illustrated in the Figure 1 . When in this closed position, the shutter (1) withstands fire. In the event of a fire, the flap (1) can be opened in the smoke extraction duct (2), as shown in Figure 2 so that it does not constitute an obstacle in the areas through which people must be evacuated.
  • the shutter (1) has a substantially rectangular section. It comprises a frame (5) which has aluminum profiles (6). These profiles (6) can be extruded.
  • the frame (5) further comprises elements of refractory material (17), intended to ensure that the structure of the frame (5) is at least partially retained in case of fire, and in the case where the flap (1) remains closed and must withstand fire.
  • a leaf (3) is mounted in this frame (5) by means of hinges (13) so that the leaf (3) can pivot in the smoke extraction duct (2) between a closed position in which the duct (2) is closed, as shown in the Figure 1 , and an open position, in which the conduit (2) is open, as illustrated in the Figure 2 .
  • a flap (1) may comprise a single leaf (3), as illustrated, but may also include several leaves (3). The manner in which it is possible to adapt the illustrated flap (1) to obtain a flap (1) of this type comprising several leaves (3) will be clear to the skilled person.
  • the illustrated leaf (3) comprises a first plate of refractory material (4), which extends essentially over the entire surface of the leaf (3).
  • This first plate (4) may for example be made of calcium silicate.
  • This calcium silicate can be self-clad, and can be fiber reinforced.
  • This plate (4) could also be made of another refractory material.
  • a second plate of refractory material (9) of the leaf (3) also extends substantially over the entire surface of the leaf (3).
  • This second refractory material plate (9) is positioned at a distance from the first plate (4).
  • This second plate (9) is for example a plasterboard. Such a plasterboard may optionally be reinforced by glass fibers.
  • This plate (9) could also be made of another refractory material.
  • the leaf (3) further comprises aluminum profiles (7), which extend essentially on the contour of said refractory material plates (4, 9), and which are positioned substantially between said plates (4, 9), such that the plates (4, 9) and the profiles (7) of the leaf (3) define an interior void (10) in the leaf (3).
  • These aluminum profiles (7) can be extruded.
  • a lock mechanism (11) for the flap (1) is further arranged between said plates (4, 9), so that this mechanism (11) is not accessible from the outside when the flap (1) is found in the closed position. Actuation of the leaf (3) can be remotely controlled and / or self-controlled using this lock mechanism (11).
  • the shutter (1) comprises a seal (8) which, when the leaf (3) is in the closed position, is positioned between the aluminum profiles (6) of the frame (5) and the aluminum profiles of the leaf (3). ), so as to seal the cold air shutter (1) when the latter is in this closed position.
  • the aluminum profiles (6) of the frame (5) have grooves in which the seal (8) is introduced.
  • the seal (8) may be made of rubber or silicone.
  • the aluminum profiles (6, 7) ensure the rigidity of the shutter (1). As they are extruded, it is easier to introduce seals (8), bars (12), hinges (13), etc., compared, for example, with steel profiles. Although these aluminum profiles (6, 7) melt at the temperatures to which they are subjected in the event of fire, the shutter (1) is fire-resistant, thanks to the elements made of refractory material (4, 9, 17), and thanks to intumescent joints (14, 15) which are additionally provided in the flap (1).
  • intumescent joints (14) are placed on the edges of the first refractory plate (4) and extend, when the shutter (1) is in the closed position, between the leaf (3) and the frame (5). ).
  • Several other of these intumescent joints (15) are positioned between the frame (5) and the wall or ceiling (16). These intumescent seals (14, 15) are positioned such that they help to ensure that the shutter (1) resists fire in the case where the flap (1) remains closed in case of fire.
  • the flap comprises a plurality of bars (12) which are connected in parallel in the frame (5), forming a grid which constitutes an obstacle in the smoke extraction duct ( 2) when the leaf (3) is in the open position.
  • the second plate (9) of the leaf (3) has corresponding grooves in which said bars (12) are accommodated when the leaf (3) is in the closed position.
  • the shutter (1) according to the invention is particularly suitable for being part of a smoke and heat evacuation system, which is intended for the mechanical smoke extraction of buildings, in order to facilitate the evacuation of people.
