Description

Technical Field

[0001] The utility model relates to the technical field of fireproof rolling shutter doors, in particular to a large-span fireproof rolling shutter door combined structure. Background Art

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. In a fixed slide, the doors rotate up and down around the scroll above the door. Rolling shutter doors play the role of horizontal separation like walls. Fireproof rolling shutter doors are a fire-proof and heat-insulating facility suitable for larger openings in buildings.

[0003] When installing existing rolling shutter doors, if the width of the installation position is greater than the width of the fire shutter door, the installation position needs to be divided before installation, which cannot meet the actual use requirements and has certain limitations on the installation position in application. In addition, most fire shutter doors are fixed to the wall with bolts. When problems occur with the fire shutter door and it needs to be replaced or disassembled for repair, in order to ensure the stability of the fire shutter door, it is necessary to re-drill the wall, which can easily cause damage to the wall. For this reason, we propose a large-span fire shutter door combination structure. Utility Model Content
