Can the fire barrier be disconnected when it meets the hole?

I can't. Fire isolation belt can't be disconnected when it meets the hole, so it should be repaired in time. When the fire isolation belt is blocked by the entrance, the fire isolation belt with equal width should be set vertically along the entrance side and intersect with the horizontal fire isolation belt. The fire isolation belt should have the function of preventing the fire from spreading. Fire isolation belt refers to the isolated space and related facilities to prevent the fire from spreading in a large area and protect the safety of life and property.
