Description

Technical Field

[0001] The utility model relates to the technical field of partition fire doors, in particular to a partition fire door that meets special applications in tunnel sections. Background Art

[0002] Tunnel partition fire doors are installed inside tunnels to separate different areas of the tunnel in the event of a fire. By isolating the fire source and smoke, tunnel fire doors provide a safer evacuation environment for people inside the tunnel, helping to reduce casualties and prevent the spread of fire and smoke. Tunnel partition fire doors are a vital component of tunnel safety facilities and are of great significance in protecting the lives and property of people within the tunnel.

[0003] In traditional double-door, two-way partition doors, a door panel support pillar is installed between the two doors to improve the door's resistance to wind pressure, supporting the partition door and enhancing its structural strength. However, traditional support pillars are welded to the door frame. If the support pillars are deformed by wind pressure during use, the entire door frame must be replaced or the support pillars must be cut and re-welded, requiring extensive maintenance. Furthermore, because the support pillars are located in the middle of the door frame, they can obstruct the doorway in some situations, limiting its opening. Utility Model Content
