By the way, most urbanites live in high-rise buildings, and when a fire occurs in a high-rise building, due to the crowded environment and the design of the building structure, the chimney effect is likely to occur, so in addition to fire-fighting and sprinkler equipment, fire doors are also installed on each floor . Fire doors are generally installed in the passageway on the side of the elevator or escape ladder. In order to facilitate the daily passage of residents, the current method is to open it normally and close it in case of fire. Requirements and other factors must have the performance of fire prevention and smoke shielding, so fire doors that open at 270 degrees are often configured.

However, in order to allow the fire doors to rotate 270 degrees, the general practice is to design the shape of the adjacent sides of the door body and the frame as a 1/4 arc or beveled angle, which will greatly increase the difficulty of the manufacturing process and the corresponding cost, otherwise It can only increase the distance between the door body and the frame, but it will reduce the ability of the fire door to block the fire and thick smoke. If the metal sheet is used to connect the door body and the frame body, it is attempted to use mutual The metal sheet is tightly attached to block the smoke, but the smoke is pervasive under high temperature and high pressure, the metal sheet cannot reliably isolate the smoke, and the place where the sheet metal can be installed with a rubber strip is limited, and it is difficult to fill this loophole. Furthermore, There is a risk of deformation of the metal sheet after reaching a certain high temperature, and it may also cause the door leaf to fail to open and close again.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction in which the creators of the present invention and related manufacturers engaged in this industry want to study and improve.
