The purpose of the present invention is to provide a smoke diffusion blocking device capable of maximizing evacuation efficiency by efficiently preventing smoke from being leaked and diffusing to other areas through various paths, such as a door gap, a hallway, a window, a gate, and the like when a building is in a disastrous situation, such as fire, and allowing people to easily come in and out. The smoke diffusion blocking device is located in a blocking target space of a building and blocks that smoke is penetrated into the blocking target space. The smoke diffusion blocking device comprises: a blocking screen which has a surface formed of a plurality of unit blocking means arranged in parallel, is provided on the upper side of the blocking target space to be wound around a winding rod to which one edge of the surface formed by connecting the unit blocking means is attached and fixed, and has a fixing bar to which the other edge opposite to the edge connected with the winding rod is fixed so that the unit blocking means are fixed to the appropriate location; a spraying unit which has a spraying means having at least one spraying hole spraying smoke blocking fluid and which is provided above the winding rod so that the unit blocking means is adjacent to the spraying hole; and a winding means rotating the winding rod around which the blocking screen is wound in order to wind and unwind the blocking screen. |
