卷簾門的設計人員應從不同建筑的性質、類型上設計有針對性的卷簾門，在設要嚴格按照消防技術規范要求，合理設置卷簾門，不得隨意降低卷簾門的等級。

The designers of roller shutter doors should design targeted roller shutter doors based on the nature and type of different buildings. During the design, they should strictly comply with the requirements of the fire technical specifications, reasonably set roller shutter doors, and should not arbitrarily lower the grade of roller shutter doors.

1、在設計封閉樓梯間和未采用正壓送風系統防煙樓梯間前室的濟南卷簾門時，應考慮卷簾門距頂棚的距離盡量不小于500mm，這樣一旦發生火災事故，可以有效防止人員疏散時煙氣進入樓梯間內，可保證樓梯間的防煙效果。

1. When designing Jinan roller shutter doors in the enclosed stairwell and in the front room of the stairwell without using a positive pressure air supply system for smoke prevention, it should be considered that the distance from the roller shutter door to the ceiling should not be less than 500mm, so that in the event of a fire accident, smoke can be effectively prevented from entering the stairwell during evacuation, and the smoke prevention effect of the stairwell can be guaranteed.

2、在設計有正壓送風系統樓梯間及其前室的卷簾門時，應考慮到單扇開啟面積與正壓送風量相匹配。如果開啟面積過大，在火災發生時，樓梯間內正壓送風系統運行的情況下由于風壓的作用，可能會造成開啟不夠順暢，不利于人員迅速疏散。

2. When designing the rolling shutter doors of the stairwell and its antechamber with a positive pressure air supply system, it should be considered that the single opening area matches the positive pressure air supply volume. If the opening area is too large, due to the effect of wind pressure during the operation of the positive pressure air supply system in the stairwell during a fire, the opening may not be smooth enough, which is not conducive to rapid evacuation of personnel.

3、在建筑內日常人流量較多、使用頻率較大的部位，應優先考慮設計常開式卷簾門。由于常開式有靠電磁釋放閥或磁力門吸、閉門器及自動控制系統來實現自閉的功能，在火災發生時能夠自行迅速關閉，起到防止火災蔓延和煙氣擴散的作用，這樣設計既有利于在火災發生時人員疏散，又能避免經常使用而出現的損壞。

3. Priority should be given to designing normally open roller shutter doors in areas with high daily pedestrian flow and high frequency of use within the building. Due to the self closing function of the normally open type, which relies on electromagnetic release valves or magnetic door suction, door closers, and automatic control systems, it can automatically and quickly close in the event of a fire, preventing fire spread and smoke diffusion. This design not only facilitates personnel evacuation in the event of a fire, but also avoids damage caused by frequent use.
