有时候济南卷帘门的质量出现缩水现象是因为卷帘门的设计及组成材料均由不合格现象，对此，就目前情况，给大家简单的介绍一下在设计过程中应注意的事项。

Sometimes the quality of Jinan roller shutter door shrinks because the design and constituent materials of roller shutter door are unqualified. For this, based on the current situation, I will briefly introduce the matters needing attention in the design process.

维修设计人员应从不同建筑的性质、类型上设计有针对性的卷帘门，在设要严格按照消防技术规范要求，合理设置卷帘门，不得随意降低卷帘门的等级。

Maintenance designers should design targeted roller shutter doors from the nature and type of different buildings. During the design, roller shutter doors should be set up reasonably in strict accordance with the requirements of fire technical specifications, and the grade of roller shutter doors should not be reduced at will.

1、在设计封闭楼梯间和未采用正压送风系统防烟楼梯间前室的卷帘门时，应考虑卷帘门距顶棚的距离尽量不小于500mm，这样一旦发生火灾事故，可以有效防止人员疏散时烟气进入楼梯间内，可保证楼梯间的防烟效果。

1. When designing the rolling shutter door in the front room of closed staircase and smoke proof staircase without positive pressure air supply system, it should be considered that the distance between the rolling shutter door and the ceiling should not be less than 500mm as far as possible, so that in case of fire accident, smoke can be effectively prevented from entering the staircase during personnel evacuation, and the smoke prevention effect of the staircase can be guaranteed.

2、在设计有正压送风系统楼梯间及其前室的卷帘门时，应考虑到单扇开启面积与正压送风量相匹配。如果开启面积过大，在火灾发生时，楼梯间内正压送风系统运行的情况下由于风压的作用，可能会造成开启不够顺畅，不利于人员迅速疏散。

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

3、在建筑内日常人流量较多、使用频率较大的部位，应优先考虑设计常开式卷帘门。由于常开式有靠电磁释放阀或磁力门吸、闭门器及自动控制系统来实现自闭的功能，在火灾发生时能够自行迅速关闭，起到防止火灾蔓延和烟气扩散的作用，这样设计既有利于在火灾发生时人员疏散，又能避免经常使用而出现的损坏。

3. In the building where the daily traffic volume is large and the frequency of use is high, the design of normally open roller shutter doors should be given priority. As the normally open type has the function of realizing self closing by means of electromagnetic release valve or magnetic door stopper, door closer and automatic control system, it can close quickly by itself in case of fire, and plays the role of preventing fire spread and smoke diffusion. This design is not only conducive to personnel evacuation in case of fire, but also can avoid damage caused by frequent use.

在卷帘门运行过程中，如果听到门或电机有异常声音，需要立即按下急停按钮，这样当卷帘门电源切断时，就需要手动开关门。当卷帘门需要下降时，拉下电机尾部的离合拉杆，卷帘门依靠自身重量可以匀速缓慢下降。

During the operation of the rolling shutter door, if you hear the abnormal sound of the door or motor, you need to immediately press the emergency stop button, so when the power supply of the rolling shutter door is cut off, you need to manually open and close the door. When the roller shutter door needs to be lowered, pull down the clutch pull rod at the tail of the motor, and the roller shutter door can be lowered slowly at a constant speed depending on its own weight.

当卷帘接近完全关闭时，松开自重下降手柄，然后再次拉动，直完全关闭。当卷帘门需要提升和打开时，可以通过拉动拉链带将其提升。注意卷帘门的手动开关和电动操作不能同时使用。

When the roller shutter is nearly completely closed, release the self weight lowering handle, and then pull it again until it is completely closed. When the rolling shutter door needs to be lifted and opened, it can be lifted by pulling the zipper belt. Note that the manual switch and electric operation of the rolling shutter door cannot be used at the same time.
