Technical Field

[0001] The utility model relates to the technical field of blocking devices, and more specifically, to a blocking device for a top plate inside a civil air defense building. Background Art

[0002] Civil defense buildings refer to buildings used to protect people's lives and property and provide shelter, protection and rescue functions. Civil defense buildings usually include underground air-raid shelters, underground shelters, underground command posts, underground passages, etc.

[0003] The roof blocking device is a safety facility in civil air defense buildings, used to block the entrance to the underground air-raid shelter or underground refuge. In the event of an emergency such as an air raid or fire, the roof blocking device can prevent smoke and harmful gases from entering the air-raid shelter or refuge, protecting people's lives. The roof blocking device is usually made of steel plates, concrete and other materials, and has the functions of fire prevention, smoke prevention and gas penetration prevention. The device is usually installed on the top of the entrance of the passage, usually in an open state, and can be closed manually or automatically when needed.
