Description

Technical Field

[0001] The utility model belongs to the technical field of smoke barrier vertical walls, in particular to a rolling curtain type vertical wall. Background Art

[0002] The rolling shutter type smoke barrier is installed under the ceiling of the building. When a fire occurs, the fire alarm system will trigger the rolling shutter wall to automatically descend, forming a barrier that effectively blocks the spread of smoke in the building. In this way, the wall can control the smoke within the fire source area and ensure the safety of the evacuation passage. Due to the poor stability of the smoke barrier and the guide rail in the related art, the curtain surface will shake when moving up and down due to lack of sufficient support; and due to the poor strength of the guide rail in the related art, the guide rail is prone to deformation after long-term use or impact by external force, resulting in the curtain surface being unable to move up and down smoothly.
