technical field

The invention relates to the technical field of building fire protection facilities, in particular to a fire door.

Background technique

Building fire protection facilities are important facilities to ensure building fire safety and personnel evacuation safety. They are an important part of modern buildings, including fire doors. Fire doors refer to fire resistance, integrity and thermal insulation within a certain period of time. Doors with high performance requirements are fire partitions with certain fire resistance, such as fire compartments, evacuation stairwells, and vertical shafts. It can effectively prevent the spread of fire, but traditional curtain fire doors only rely on their own fireproof materials to play the role of fireproof and heat insulation. In some persistent fire situations, the performance of fireproof materials will continue to decline with the passage of fire time until they fail completely. There are also many stainless steel fire doors used alone in the prior art. For example, Chinese patent 201920035748.3 discloses a new type of stainless steel fire door, including a mounting frame (1), a fire door (2) and a switch device (3), which is characterized in that : A chute is provided inside the mounting frame (1), the fire door (2) is inserted into the chute of the mounting frame (1), and the fire door (2) includes a stainless steel layer (21), insulation and heat insulation A layer (22), a buffer layer (23) and a sound insulation layer (24), the buffer layer (23) is adhered to the outer surface of the sound insulation layer (24), and the insulation and heat insulation layer (22) is adhered to the buffer layer (23) outer surface, the stainless steel layer (21) is bonded to the outer surface of the insulation layer (22); the switch device (3) is fixedly connected to the top of the mounting frame (1), and the switch device (3) ) includes an inner turntable (31), a rotating gap block (32), a wheel disc (33), a turning rod (34), an installation box (35), a connecting rod (36), an outer turntable (37) and a fixing frame (38) , the mounting box (35) is welded with the top of the mounting frame (1), the inner turntable (31) is located inside the mounting box (35), and is rotatably connected to the middle of the inner cavity of the mounting box (35), and the rotation gap The block (32) is welded to the outer wall of the inner turntable (31), the wheel disc (33) is rotatably connected to both sides of the middle part of the inner cavity of the installation box (35) through the connecting shaft, and the rotating rod (34) is connected to the wheel disc (33). ) welding on the front side, the center of the outer turntable (37) is welded with the center of the inner turntable (31) through the connecting shaft, and the fixing frame (38) passes through the mounting frame (1) and the top of the fire door (2) By welding, the fixing frame (38) is fixedly connected with the outer turntable (37) through the connecting rod (36).
