Definitions

  • the present invention relates to a device for rapidly evacuating smoke (also called an "outlet") and heat for buildings such as, in particular, industrial premises or those receiving the public (so-called ERP premises), making it possible, by in the event of fire, to clear a hopper delimiting an opening in the roof, either by unlocking, or by means of a control system which can be, for example, manual, electro-mechanical, pneumatic, or other.
  • a control system which can be, for example, manual, electro-mechanical, pneumatic, or other.
  • Devices of this type which can also be used as aeration means constitute safety equipment which must equip factories, workshops or ERP premises. They are generally designed to be able to intervene either automatically or manually, when it occurs, for example in the event of a fire, the release of smoke and / or an abnormal rise in ambient temperature, this intervention consisting in opening a movable shutter covering an opening provided in the roof of the building and through which the smoke can escape and the heat.
  • This intervention consisting in opening a movable shutter covering an opening provided in the roof of the building and through which the smoke can escape and the heat.
  • a number of rapid smoke evacuation systems are known which meet the concerns set out above.
  • These various known systems consist, in general, of a hopper delimiting in the roof of the building an opening, generally rectangular, covered by a movable closure means, most often constituted by a frame composed either of a sheet metal or polyester plate, or of windows, or of one or more transparent domes, or further blades, said chassis being articulated on hinges at the upper cross member, and ventilation being obtained by action on the lower cross member of the chassis, for example using conventional means such as, in particular, rack, rods, arms , etc ...
  • the currently known leaf outlets have the disadvantage of comprising opaque blades generally of steel or aluminum and, consequently, if they can, independently of their role in the event of fire, also serve for the ventilation of the premises, they do not constitute day wells, because of their opacity.
  • the present invention proposes to provide an outlet for blades which does not have these drawbacks.
  • this invention relates to a device for aeration and evacuation of fumes, in particular for industrial premises, comprising a hopper on which rests a frame consisting of articulated blades, this device being characterized in that it comprises: a frame of which two opposite banks are provided with notches forming housings designed so as to receive a plurality of regularly spaced transverse chutes; a plurality of articulated blades, preferably transparent, mounted on blade holder gussets so that each blade rests on the upper edges of the troughs, as well as on the upper edges of the edges provided with said housings, and a linkage system articulated on said blade holder gussets, so as to ensure the control of the blades and their opening preferably at 90 relative to the plane of the hopper.
  • each chute has an upper longitudinal edge constituted by a cylinder, and the articulation of the blade holder gussets is effected along the axis of this cylinder, which is chosen to be of small diameter.
  • each chute there is provided in the middle of each chute, on the face opposite to that of the edge carrying the cylinder, a small boss, or equivalent, ensuring the blocking of the lower part of each blade when it is perpendicular to the hopper plane.
  • each blade end is provided with a profile made of a flexible material, for example of elastomer, rubber or butyl-neoprene, in order to seal the surface formed by all the blades.
  • the device according to the invention comprises a conventional type curb 10, placed on a rectangular or square hopper, and a frame 12, subject to the curb.
  • This frame has two front edges 14, 14 ', and two side edges 16, 16'.
  • These edges 16, 16 ′ are provided with notches such as 18, regularly spaced, designed so as to receive transverse chutes such as 20.
  • the profile of these chutes appears clearly in FIG. 3. They consist of a profile, preferably with a rectangular section, an upper edge of which is constituted by a cylinder 22, the role of which will be explained below.
  • the shutter member of the device of the invention consists of a plurality of transparent or non-transparent blades, such as 24, for example made of glass or plastic.
  • Each blade 24 is held by a blade holder gusset 26, 28, as can be seen in FIG. 3.
  • the successive blades 24, in horizontal position each rest on the upper edges of the troughs 20 , as well as on the upper edges of the edges 16, 16 ′ provided with the notches.
  • a profile 30 for example of rubber, butyl-neoprene or aluminum, a seal is obtained over the entire surface formed by the blades 24.
  • the blades 24 are maneuvered by a system of connecting rods 34, connected to the ends of the gussets 26, in order to obtain a clearance of approximately 90 ° of the blades relative to the plane of the hopper.
  • the opening of the blades is controlled using opening springs 40, released by conventional means such as, in particular: cable, fusible link, electro-magnetic link, pneumatic cylinder, etc.
  • the springs 40 working in tension or compression can be replaced by commercially available pneumatic thrust cylinders.
  • the originality of the device according to this invention resides in particular in that one / of the transverse upper edges of the troughs is constituted by a cylinder 22, the articulation of the gussets 26 taking place along the axis of this small diameter cylinder. Thanks to this characteristic, the blades 24, during their rotation, are constantly supported by a generator of the cylinder on which they slide. It is thus possible to provide long-reach blades, which do not buckle during opening. In addition, one can provide in the middle of each chute, on the face opposite to that provided with the cylinder 22, a small boss (not shown) ensuring the blocking of the lower part of the blade, when the latter is perpendicular to the plane of the hopper.
  • a lever 42 wedged on the shaft 32 and actuated, for example, using a cable 44.
  • the lever 42 has been shown in the axis of the hopper; without departing from the scope of the invention, it can be located at the edge, either on one side or the other, of frame 12.
  • the linkages 34 have been shown outside this frame 12, in order to obtain maximum aeraulic efficiency.
  • the shaft 32 ensuring the connection of the connecting rod system, has been shown to the right of the first rear blade; however, depending on the type of control used, it can be positioned at any point in the hopper.
  • a frame with vertical walls 46 which constitutes a windbreak, and which improves the device performance, in particular by venturi effect.
  • the outer frame 46 is provided sufficiently high so that it can receive blades 47 inclined, for example at an angle of the order of 60 °, so that the vertical from the upper edge A of a blade passes through the lower edge B of the next blade, it is possible to collect, in troughs 48 provided at the bottom of each of the blades 47, the rainwater which pours on the face sky side of each of the blades 47. If, moreover, the lower edge C of the chutes 48 located at the bottom of the blades 47 is vertical to the transverse troughs 20, the possible drops of runoff water on the troughs 48 will fall into the troughs 20.
  • the rainwater is evacuated for the most part by the troughs outside the outer frame 46 (see FIG. 7), the surplus being evacuated by the troughs 20, whether the blades 24 are open s or closed.
  • An all-weather aerator is thus obtained, which can also serve as a smoke outlet.
  • the blades 24 can also be opaque, translucent or transparent, in the same way as the blades s 47 (aluminum, glass, etc. can be used). This provides an all-weather outlet aerator, also allowing clarity to pass.
