[0002] The smoke barrier wall is made of non-combustible material, a fixed or movable smoke barrier facility that hangs down from the ceiling by no less than 500mm, and is vertically installed under the building ceiling, beam or suspended ceiling. The smoke barrier wall is divided into fixed smoke barrier wall and movable smoke barrier wall according to the installation method; it is divided into flexible smoke barrier wall and rigid smoke barrier wall according to the stiffness performance of the smoke barrier component material. It is mainly used in high-rise or super high-rise large shopping malls, office buildings, warehouses and other occasions, and can effectively block the horizontal flow of smoke under the building ceiling.

[0003] Currently, smoke barriers are divided into fixed or roller-type, and the roller-type smoke barrier cloth needs to be wound on the surface of a roller. However, when the smoke barrier cloth is wound and unfolded on the roller surface, due to the deformable nature of the smoke barrier cloth itself, it is easy to cause wrinkles on the smoke barrier cloth during the winding process and after unfolding. Therefore, in order to solve the above problems, we provide a ceiling embedded smoke barrier wall. Utility Model Content
