Description

Technical Field

[0002] A fireproof roller shutter track disclosed in CN207260939U includes a track body and a door installed inside the track body. The track body is U-shaped with two right angles at its bottom corners. The ends of the two side walls of the track body are bent inward to form square grooves. The openings of the square grooves face inward and gradually decrease in size. Sealing smoke-proof strips are inserted into the square grooves on both sides of the track body. The sealing smoke-proof strips are in frictional contact with the door.

[0003] The system features sealing smoke-proof strips on both sides of the track body that make frictional contact with the door, creating airflow at the fire scene and preventing gaps from forming in the door. This improves the smoke and fire protection performance of the fire-resistant roller shutter door. The sealing smoke-proof strips are held in place by bending one side wall of the square groove in the track body. The simple square groove structure facilitates production and improves efficiency.
