Definitions

  • a current official requirement concerning smoke control for fire precautions in such building structures is a fire ventilation opening area equivalent to five percent of the largest floor served by the atrium.
  • a system ventilator for this purpose comprising a light-­weight hollow frame made up of corner connecting members and tubular frame side members connected together by the corner members, said frame surrounding and defining a fire ventilation opening, a ventilation flap hinged on the frame along one edge of the flap for outward opening movement and inward closing movement from closed and open positions respectively, said ventilation flap in its closed position blocking and weather-sealing the fire ventilation opening and in its open position allowing the exhaustion of smoke, heat fumes and gases through said opening, a pair of control lever arms each hinged at its two ends respectively to the flap and to a linearly movable slider means mounted inside said hollow frame and a pair of linear actuators also mounted inside said hollow frame, said actuators being operatively connected one with one of the slider means and the other with the other of the slider means to displace the slider means and close the flap.
  • one opposite pair of the frame members has inner tubular parts which receive corner members plugging the respective ends of said inner tubular parts.
  • the louvred ventilator shown in Fig. 1 comprises a frame generally indicated at 100 made up of a pair of tubular side frame members 102 (see also Figs. 2 and 4 ) a bottom frame member having an inner tubular part 104 (see Fig. 2 ) a top frame member having an inner tubular part 106 and a single bank of eight louvre blades 108.
  • the tubular frame members or parts 102, 104 and 106 and the louvre blades 108 are formed from lightweight aluminium extrusions.
  • the side frame members 102 are two-part members and are formed in two extruded parts, namely a channel-form part 102 a having a cross-section as shown in Fig.
  • the infill part 102 b or 102 c or 102 d is fitted to the channel-form part 102 a to form the tubular frame member 102 in a manner hereinafter described, the infill part being received on the rebates 102 e (see e.g. Fig. 4 ) of the channel-form part.
  • the side frame members 102 have lengthwise running gutters 102 g having inner walls 102 h (see Fig. 2 ) later referred to.
  • the top and bottom frame members are completed by respective header and sill plates 130 and 131 which are attached to the bolt head retaining grooves 112 of the top and bottom frame member parts 106, 104.
  • These header and sill plates are formed with the fixing flanges 130 b and 131 b corresponding to the fixing flanges 114 b for fixing in the place of glazing in curtain walling and glazing systems as already described above.
  • the plates 130 and 131 may be formed with fixing beads or flanges 130 c , 131 c or 130 d , 131 d as shown in Figs. 15 to 18 to suit different fixing requirements for the ventilator.
  • the pins 142, 142′ may be enlarged inwardly of the holes in the plugging members 140, 140′ to help in holding the pins securely in the holes. Sealing lips 140 e and 140 f defined by the slots 140 a may be likewise bonded with the outside surfaces of the louvre blades 108.
  • the pneumatic rams 158 are fixedly mounted to the side frame member parts 102 a and each ram houses a return spring operable to open the louvre blades.
  • the control arms 151 are pivoted to the control link bar 150 by pivot pins mounted on adjustable sliders on the bar 150. During assembly, the sliders are fixed to the bar 150 with screws while the louvres are clamped closed so that the louvre blades close tightly against each other.
  • Fig. 22 illustrates a version of the ventilator having a single,bottom hung, outwardly opening hinged ventilation flap 159, the side frame members 102 of which correspond with those already described.
  • the top and bottom inner frame members parts 160 and 162 have cross-sections as shown in Figs. 23 and 24 respectively.
  • the force-fitted plugging members 163, 164 for the ends of these sections are as shown in Figs.25 and 26 and are formed generally as described for the force-fitted plugging members 124, 126 except that they are adapted to the profile of the sections 160, 162 respectively.
  • the control gear 169 operates control level arms 170 hinged at their two ends respectively on hinge pins 170 a and 170 b to the flap frame 168 and to slider carriages 171 of ball bearing linear motion sliders 172 fixed to the inside of the side frame member parts 102 a and pivoted latching hooks 173 mounted on blocks 174 fixed to the parts 102 a .
  • the pins 170 b pass through slots in the side frame member parts 102 a and in the sliders 172 to connect with the carriages 171 and likewise, the latching hooks 173 pass through slots in the parts 102 a .
  • the rams 176, 177 are provided with return springs (not shown) for reverse operation, the return springs of the rams 176 operating initially to pivot the flap 159 open after the return springs of the rams 177 have operated to release the latches 173, 179, the flap being moved to its fully open position by gravitational action.
  • top and bottom frame member parts 160 and 162 are completed with header and sill plates having fixing flanges or beads to match the fixing flanges or beads on the infill parts 102 a of the side frame members 102, as previously described.
  • the frames thus produced are sufficiently rigid for the purpose required in as far as each frame is stabilized in use, by the perpendicular lightweight building structure into which the frame is finally assembled.
  • the bolt-on or clip-on interchangeable outer frame parts enable the ventilators to be readily adapted to interfit with a variety of building walling systems.
  • the ventilator described with reference to Figs. 22 to 26 having a single, outwardly opening fire flap is restricted for use in vertical walling
  • the louvred fire ventilator described with referece to the drawings may be utilized in curtain walling or glazing extending in an inclined plane.
