Technical Field

[0001] The invention relates to the technical field of roof smoke barrier vertical walls, and in particular to a movable smoke barrier vertical wall structure for a slope roof. Background Art

[0002] A fixed or movable smoke barrier made of non-combustible material, which is not less than 500 mm from the ceiling. A movable smoke barrier is a smoke barrier that automatically droops due to the action of temperature, smoke or other control equipment in the event of a fire. It is mainly used in high-rise or super-high-rise large shopping malls, office buildings, warehouses and other places. It can effectively block the horizontal flow of smoke under the building ceiling to improve the smoke exhaust effect in the smoke-proof partition, and play a certain role in protecting people's lives and property.

[0003] At present, fixed smoke barriers are mostly used for setting up sloping roofs. Conventional movable smoke barriers cannot meet the requirements for setting up sloping roofs. Fixed smoke barriers, especially those made of steel plates, gypsum boards, fireproof glass and other materials, are usually thick and heavy. The load-bearing capacity of the building needs to be considered during installation. Sometimes additional supporting structures need to be added, which increases the installation cost and complexity. At the same time, in order to ensure the fire prevention effect, the design of fixed smoke barriers is often relatively simple, which affects the height of space use and may have a certain impact on the interior decoration style, especially in places that focus on aesthetics.
