Problems solved by technology

[0006] In this way, since there is a certain distance between the traditional smoke-retaining wall 10 and the bottom end of the stairs B, the harmful gas is only blocked by the smoke-retaining wall 100 in a short time when a fire occurs, so the harmful gas can easily flow through the smoke-retaining wall. wall, which may cause suffocation

Embodiment Construction

[0036] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] It should be noted that like reference numerals designate like elements throughout the drawings. Here, for the purpose of clarity, detailed descriptions of related functions or elements known in the art will be omitted.

[0038] It should be noted that the basic concept of the present invention is to prevent the rapid movement of harmful gases while allowing the movement of evacuees by allowing a part of the passageway (staircase) to be closed from the harmful gas or heat in case of fire, thereby protecting the evacuees from harmful gas.

[0039] Hereinafter, typical embodiments of the present invention based on such a basic concept are described with reference to the drawings.

Abstract

The present invention relates to a smoke barrier screen device to be installed on the ceiling of a path or a stairway in which humans pass, wherein the smoke barrier screen device operates and a smoke barrier screen thereof gets closer to the floor upon the outbreak of a fire to protect humans from noxious gases.; To accomplish the above object of the present invention, a smoke barrier screen device is provided that comprises a sensing unit installed on a ceiling to sense noxious gases generated upon the outbreak of a fire, operating means having a stopper member movably fixed at one side of a smoke barrier wall, one end of which is fixed at the ceiling and the other end of which is free, such that the stopper member responds to applied power, an accommodating member, one end of which is fixed at the smoke barrier wall and the other end of which gets caught by and is released from the operating means in response to the operation of the operating means, a smoke barrier screen member, one end of which is connected to and accommodated in the accommodating member,; such that the smoke barrier screen member is spread in response to the operation of the operating means to cut the flow of noxious gas and enable people to escape from the fire, and a control unit for controlling the operating means in response to the signal applied by the sensing unit.

Description

technical field [0001] The present invention relates to a kind of smoke screen device, more particularly, relates to a kind of smoke screen device installed on the ceiling of the channel or staircase used by the evacuation personnel in the building, and the smoke screen device utilizes the fire generated when a fire occurs Noxious gas or heat is operated to provide an effective barrier to noxious gas, thereby protecting evacuees from suffocation caused by noxious gas. Background technique [0002] Usually, passages or stairs in buildings such as subway stations or underground shopping centers are equipped with smoke barriers to block the movement of harmful gases (smoke) produced when a fire occurs. [0003] figure 1 It is a schematic side view of a traditional smoke barrier installed in a subway station. [0004] Such as figure 1 As shown, the smoke blocking wall 10 is fixed to the ceiling A at one end thereof, and faces the width direction of the stairs B, so as to prev...
