Description

Technical Field

[0001] The utility model relates to the technical field of smoke barrier vertical walls, in particular to a movable smoke barrier vertical wall. Background Art

[0002] Smoke barrier walls are a type of facility made of non-combustible materials. They are mainly used in high-rise or super-high-rise shopping malls, office buildings, warehouses and other places. They can effectively block the horizontal flow of smoke under the building ceiling, improve the smoke exhaust effect within the smoke-proof zone, and play a positive role in protecting people’s lives and property.

[0003] Movable smoke barriers can automatically droop in the event of a fire through the action of temperature sensors, smoke sensors or other control equipment to form a smoke zone partition, thereby isolating the smoke. In the existing technology, most movable smoke barriers require a set of fixed guide rails when in use, and the guide rails are used to realize the up and down movement of the movable smoke barriers. The production cost is relatively high, and the gap between the fireproof cloth and the guide rails will get stuck over time, thereby affecting the normal use of the movable smoke barrier, making it impossible to isolate the smoke in time, and the practicality is insufficient. Therefore, it is necessary to redesign the movable smoke barrier to address the above problems. Utility Model Content
