<p><P>PROBLEM TO BE SOLVED: To solve the problem that operation efficiency is reduced due to attachment and detachment of screws or fixation using fasteners allows only a gap between an upper frame of a jamb and a door panel to be airtight, though a method using mounting screws and fixation by fasteners are proposed before as a method of fixing an airtight material to the door panel or the like so as to provide a door with a smoke shielding function. <P>SOLUTION: A smoke shielding device includes an airtight material 17 which is fitted to a door panel 8 to seal the gap between the jamb 4 and door panel 8 by coming into contact with the jamb 4, and made of an elastic body; and an elastic member 10 for fitting the airtight material 17 to the door panel 8. The elastic member 10 has a nip part 10a which can be elastically spread, and is fixed to the jamb 4 and detachably fitted to the door panel 8 by elastically nipping a base part 6a of a holding material 6 fitted with the airtight member 17 with the nip part 10a. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
