In order to provide shelters for workshop workers in case of fire, safety doors are installed in the workshops. Behind the safety doors is a safety room or office. . Safety doors can effectively delay the spread of fire when a fire occurs and buy time for rescue, but the existing safety doors are limited in fire-resistant duration because they are pure entity doors. In order to effectively prevent flames from entering the safety room behind the safety door, and to enhance the fire-resistant duration of the safety door, the thickness of the safety door is generally large, so its weight is particularly heavy. Some safety doors are so heavy that they have to be installed on the wall. Inside, these ...
