Fireproof rolling shutter doors are mainly used to separate large spaces and form fire compartments, playing a highly visible role in separating them. The advantage of fireproof rolling shutter doors is that they can provide good decorative effects after being folded up, and can also indicate people's escape routes in fire accidents through eye-catching and strong penetrating colors in fire compartments, buying time for effective escape. Hard fast rolling shutter doors can be equipped with one-step and two-step lowering on the fire resistant roll control box according to on-site needs.
In high-rise buildings, the selection and layout of effective fire separation areas for special grade fire resistant rolling shutters have become the key to enabling them to achieve their expected effective fire protection functions.
So the installation and maintenance personnel of Jinan fire resistant rolling shutter doors believe that it is necessary to strike a balance between not affecting normal life and effective fire separation. Generally speaking, when there are corridors, open stairs, escalators, conveyor belts and other openings connecting the upper and lower floors in high-rise buildings, the upper and lower connecting floors should be considered as a fire compartment. The sum of the allowable Z large building area for hard fast rolling shutter doors should not exceed the fire compartment building area set based on their building level.
When there are partition facilities such as fire resistant rolling curtains or water curtains with a fire resistance limit greater than 3.00h at the upper and lower openings, their area may not be calculated by superposition. For corridors and passages connecting the room and the atrium, hard fast rolling shutter doors should be equipped with Class B fire doors or fire resistant rolling shutter partitions with a fire resistance limit greater than 3.00 hours.
The partition setting of fireproof rolling shutters also has a certain scientific basis and cannot be designed and installed casually. The quality of setting up fire zones directly affects the safety of people's lives and property. For more related matters, come to our website http://www.jnyuqilin.com consulting service
