很多案例表明卷帘门的质量出现缩水现象，这与卷帘门的设计及组成材料均由不合格有着关系，对此，就目前情况，给大家简单的介绍一下在设计、安装、使用过程中应注意的事项。

Many cases show that the quality of the rolling shutter door has shrunk, which is related to the unqualified design and composition materials of the rolling shutter door. In this regard, based on the current situation, I would like to briefly introduce the matters needing attention in the process of design, installation and use.

卷帘门设计事项

Design matters of rolling shutter door

1、在不使用正压送风系统的楼梯间设计封闭楼梯间和卷帘门时，防止烟雾进入楼梯间，可以保证楼梯间的防烟效果。

1. When the stairwell without positive pressure air supply system is designed to close the stairwell and rolling shutter door, smoke can be prevented from entering the stairwell, which can ensure the smoke prevention effect of the stairwell.

2、楼梯间及其前室卷帘门在设计正压送风系统时，应考虑单台风机的开启面积与正压送风量相匹配。如果开口面积过大，一旦发生火灾，楼梯间正压送风系统运行时，由于风压的影响，开口可能不够顺畅，不利于人员快速疏散。

2. When designing the positive pressure air supply system for the rolling shutter door of the staircase and its front room, the open area of a single fan shall be considered to match the positive pressure air supply volume. If the opening area is too large, in case of fire, the opening may not be smooth enough due to the influence of wind pressure during the operation of the positive pressure air supply system in the staircase, which is not conducive to the rapid evacuation of personnel.

3、由于常开型具有通过电磁释放阀或磁吸门、闭门器及自动控制系统自动关闭的功能，发生火灾时可自行快速关闭，可防止火势蔓延，烟雾的蔓延。该设计既便于发生火灾时的疏散，又避免了频繁使用造成的损坏。

3. As the normally open type has the function of automatically closing through the electromagnetic release valve or magnetic suction door, door closer and automatic control system, it can automatically close quickly in case of fire, so as to prevent the spread of fire and smoke. The design not only facilitates evacuation in case of fire, but also avoids damage caused by frequent use.

卷帘门安装事项

Installation of rolling shutter door

1、安装门框、门扇时，应按门的开启方向向疏散方向开启。

1. When installing the door frame and leaf, the door shall be opened to the evacuation direction according to the opening direction of the door.

2、门框与围墙的距离不宜过大。必要时应填入水泥砂浆或岩棉进行封堵。

2. The distance between door frame and enclosure should not be too large. If necessary, cement mortar or rock wool shall be filled for plugging.

3、避免门框与地面距离过大。如果形成门槛，不利于人员疏散。

3. Avoid excessive distance between the door frame and the ground. If a threshold is formed, it is not conducive to personnel evacuation.

4、安装双扇门时，确保门扇贴紧。

4. When installing the double door, ensure that the door leaf is close.

5、门框不宜自行制作，应购买正规卷帘门安装。

5. The door frame should not be made by itself, but should be installed by purchasing a regular roller shutter door.

6、安装卷帘门时，应注意其气密性是否良好。

6. When installing the rolling shutter door, pay attention to whether its air tightness is good.

7、坚决杜绝偷工减料，安装时亲自检查。

7. It is strictly prohibited to cut corners on work and materials, and it is required to conduct personal inspection during installation.

卷帘门维护事项

Maintenance of rolling shutter door

1、防止设置在疏散走廊、防烟楼梯间前室或共用前室的常闭卷帘门在使用过程中被人为正常开启，成为“常开”卷帘门。“打开”的卷帘百叶窗无法阻挡烟雾和火灾。

1. To prevent the normally closed roller shutter door set in the front room of evacuation corridor, smoke proof staircase or shared front room from being opened normally and becoming a "normally open" roller shutter door. "Open" roll up blinds cannot stop smoke and fire.

2、经常检查卷帘门的完整性，检查闭门器和定序器是否好用，卷帘门是否能按顺序自行关闭，合页和合页上的螺丝是否松动，以及如有损坏，应立即修理。

2. Frequently check the integrity of the rolling shutter door, check whether the door closer and sequencer are easy to use, whether the rolling shutter door can be closed automatically in sequence, whether the hinge and the screws on the hinge are loose, and if damaged, repair them immediately.

3、单位对装饰效果的片面追求，取消卷帘门的门框，只设置普通木头做的门套，用其他材料代替原来的门扇框，大面积涂抹装饰面层，从而破坏防火涂层。没有防火效果。

3. Eliminate the one-sided pursuit of decorative effect of the unit, cancel the door frame of the rolling shutter door, only set the door pocket made of ordinary wood, replace the original door leaf frame with other materials, and paint the decorative surface layer on a large area, thus damaging the fire-proof coating. No fire protection effect.

4、济南卷帘门厂建议大家要定期对常开卷帘门进行测试，检查其自闭控制系统、闭门器、定序器、释放开关等是否使用方便，发生火灾时是否能有效关闭功能，并在同时要坚决防止在常开的济南卷帘门旁乱堆放物品。

4. Jinan rolling shutter door factory suggests that we should regularly test the normally open rolling shutter door, check whether its self closing control system, door closer, sequencer, release switch, etc. are convenient to use, and whether it can effectively close the function in case of fire, and at the same time, we should resolutely prevent random stacking of goods near the normally open Jinan rolling shutter door.
