So that each can be locked It is made of a locking member in which stop pieces are formed protruding at regular intervals, the smoke-proof screen member is formed of a flame-retardant resin, and one end is fixed to the lower part of the other end of the vertical piece. A plurality of screen plates and a hole are formed so that one end is fixedly connected to the other end of the screen plate, and the other end is locked to a locking piece formed on the locking member of the operating portion. The screen plate is made up of a hanging piece formed with a locking hole so that it is possible, but when the screen plate is opened, movement of evacuees is possible and smoke movement is blocked. One end is fixed to the bottom surface of the vertical plate so that they partially overlap each other, and the central part is thin, short-circuited so that it can be quickly short-circuited by the heat moving during a fire. A piece is formed. Smoke vertical wall screen apparatus according to 6.   In the construction of a screen device for smoke barriers installed on the ceiling of the aisle so that the movement of harmful gases generated in the event of a fire is blocked and the movement of evacuees is possible, it is installed on the ceiling of the stairs. It is installed on the ceiling to block the movement of harmful gas generated in the event of a fire, and is equipped with a sensing unit provided to detect the harmful gas generated in the event of a fire, and that the sensing unit has a harmful gas. Operating means that can be fixed to the ceiling so as to be operable when power is applied, and one end locked to the operating means and the other end fixed to the ceiling to operate the operating means And a pivoting means having one end pivotably supported so as to correspond to, and released in a locked state so as to correspond to the pivoting of the pivoting means, and one end close to the bottom surface One end is locked to be opened as The other end is a screen member for smoke prevention that can be fixed to the other end of a fixing bracket whose one end is fixed to the ceiling, and a power source is applied to the operating means shaft upon application of a signal sensed from the sensing unit. A screen unit for a smoke-proof hanging wall, comprising: a control unit provided so as to be enabled.   The actuating means is provided in a bracket fixed to the ceiling via a screw, and has a differential bar that is operated forward and backward by a power source applied from the control unit, and the differential bar An actuating connecting member that is pivotally connected to one end and has a through hole formed in the lower center portion so as to penetrate the support bar of the rotating means, and is rotatable to the other end of the actuating connecting member The outer peripheral surface is configured by a pressure roller provided to be capable of supporting and supporting the rotation means. The rotation means is spaced a predetermined distance from the ceiling and can be fixed at one end. So that the pressure roller is supported on the front surface by moving the pressure roller in correspondence with the movement of the pressure roller. Both can be rotated by their own weight. A rotation member provided with a plurality of hanging pieces formed at regular intervals so that an insertion groove is formed on the surface, and the smoke-proof screen member can be locked at the lower end of the front surface; The both ends of the fixed piece are connected to each other by welding, and the support member is provided so as to be able to pass through the through hole of the operation connecting member. The smoke-proof screen member is opened. The evacuee is transparently provided so that the moving path can be seen, and is formed flexibly with a polyester resin or the like so as not to damage the evacuee, and is provided with the same width as the length of the rotating member. The other end is fixed to a fixed bracket fixed to the ceiling, and one end is evacuated easily and quickly so that the smoke-proof screen member can be opened to the part close to the bottom of the staircase. Possible In this way, a large number of smoke-proof screen pieces are formed by being incised at regular intervals, and the end of the smoke-proof screen piece is locked with a hanging piece of a rotating member passing therethrough. In addition, a smoke-proof screen member is installed in the middle portion of each of the smoke-proof screen pieces so as to be engaged with the hanging pieces, thereby obstructing the movement of a passerby. 19. The screen device for a smoke-proof hanging wall according to claim 18, wherein fixing holes are formed so that the locking ring can be fixed so as not to occur.   The actuating means is installed in a bracket fixed to the ceiling through a screw and is embedded in the ceiling so as to receive a signal sensed from a sensing unit installed on the ceiling. A differential bar that can be moved forward and backward by a power source applied from the power source, and an end of the differential bar that can be rotated via a pin and fixed at one end to the ceiling. The anti-rotation device according to claim 18, wherein the other end is constituted by a pressure roller provided to press and support a rotating member of a rotating means rotatably provided by its own weight. Smoke wall screen device.
