Product features
The curtain of the steel side to fire and smoke screen (side compound type) is suspended in the upper guide rail, along the guide rail, and the curtain is opened and closed. It has the characteristics of small frictional resistance, curvilinear motion, large span opening and small space on the upper part of the guide rail.
Using range
It is suitable for fireproof separation in large span, curve and low space, such as atrium and underground parking garage.
Type and performance metrics.
(1) open the inspection door with a width of 600mm and more than 1200mm on the side of the coil machine.
(2) it is recommended to make two widths for side volumes with a width of more than 30m.
(3) box height = side volume see light height +30O mm.
(4) when the roll curtain travel > 20m, the height is less than 3m, and an auxiliary coil machine should be added every 10 meters. The auxiliary coiler and the dial shaft should be run synchronously.
size
The maximum opening width is no more than 45m, the maximum hole height is less than 8m curve movement, and the minimum bending radius is greater than 800mm. Guide height =150mm,
Box height = scroll height +(200 ~ 400mm).
There is no need to orbit, the screen is 20mm from the floor, and the bottom of the roller is less than 50mm.
