PRESSURIZED SMOKE PREVENTION FACILITY AND SHIELDING APPARATUS

To provide a pressurized smoke prevention facility capable of reducing the amount of air supplied by an air supply facility; and to provide a shielding apparatus applied to the pressurized smoke prevention facility.SOLUTION: In a pressurized smoke prevention facility, a door 27 is provided on a smoke shield opening 14 for connecting an adjacent room 15 to an ancillary room 13. Further, the pressurized smoke prevention facility has an exhaust facility for exhausting the adjacent room 15, and an air supply facility for supplying air to the ancillary room 13. The pressurized smoke prevention facility has a shielding apparatus 30. The shielding apparatus 30 has a shielding part 32 comprising a nonflammable material capable of covering an upper area 29 enclosed by a smoke shield opening upper limb 14a of the smoke shield opening 14 and a door upper limb 27a of the door 27.SELECTED DRAWING: Figure 2 【課題】給気設備による給気量を低減することのできる加圧防排煙設備、および、加圧防排煙設備に適用される遮蔽装置を提供する。【解決手段】加圧防排煙設備は、隣接室１５と付室１３とを連絡する遮煙開口部１４に扉２７が設けられている。また、加圧防排煙設備は、隣接室１５を排気する排気設備と、付室１３に給気する給気設備と、を有する。加圧防排煙設備は、遮蔽装置３０を有する。遮蔽装置３０は、遮煙開口部１４の遮煙開口部上辺１４ａと扉２７の扉上辺２７ａとに囲まれる上部領域２９を覆うことが可能な不燃性材料からなる遮蔽部３２を有する。【選択図】図２
