[0002] The smoke barrier wall is a fixed or movable smoke barrier made of non-combustible materials and droops from the ceiling by no less than 500 mm. In case of fire, the smoke barrier wall will automatically droop due to the action of temperature, smoke or other control equipment. It is mainly used in high-rise or super high-rise large shopping malls, office buildings and warehouses. It can effectively block the horizontal flow of smoke under the building ceiling, so as to improve the smoke exhaust effect in the smoke-proof partition, and play a certain role in protecting people's lives and property. The smoke barrier wall track is a special track system used to support and position the smoke barrier wall. It is usually installed under the ceiling or floor slab, and is used in conjunction with the smoke barrier wall to block the horizontal flow of smoke and hot gases under the building ceiling in case of fire.
