In recent years, the quality of the rolling shutter door in Jinan has shrunk, and the design and composition materials of the rolling shutter door are all unqualified. In this regard, according to the current situation, we will briefly introduce the matters needing attention in the process of design, installation and use

一、设计合理，选型得当：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。

1、 Reasonable design and proper selection: maintenance designers should design targeted rolling shutter doors according to the nature and type of different buildings. In the design, the rolling shutter doors should be set reasonably in strict accordance with the requirements of fire protection technical specifications, and the grade of rolling shutter doors should not be lowered 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 doors in the front room of enclosed staircases and those without positive pressure air supply system, the distance between the rolling shutter door and the ceiling should not be less than 500mm as far as possible. In this way, once a fire accident occurs, smoke can be effectively prevented from entering the stairwell during evacuation and the smoke prevention effect of the staircase can be ensured.

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 doors of staircases with positive pressure air supply system and its front room, the matching of single leaf opening area and positive pressure air supply volume should be considered. If the opening area is too large, in case of fire and the positive pressure air supply system in the staircase is running, due to the effect of wind pressure, the opening may not be smooth enough, 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. The design of normally open rolling shutter door should be given priority in the parts with large daily pedestrian flow and frequent use. Since the normally open type has the function of self closing by means of electromagnetic release valve or magnetic door suction, door closer and automatic control system, it can close itself quickly in case of fire and prevent the spread of fire and smoke. This design is not only conducive to evacuation in case of fire, but also can avoid damage caused by frequent use.

2、 Installation specification, quality control: in the installation of Jinan rolling shutter door, must choose qualified products, not reduce the level, and should be installed in strict accordance with the specifications

1、安装门框、门扇时应根据门的开启方向，向疏散方向开启。

1. When installing the door frame and door leaf, it should open to the evacuation direction according to the opening direction of the door.

2、门框距四周的墙体不宜过大，必要时应填充水泥砂浆或岩棉进行封堵。

2. The distance between the door frame and the surrounding wall should not be too large. If necessary, it should be filled with cement mortar or rock wool for sealing.

3、避免门框离地面距离过大，若形成门槛则不利于人员疏散。

3. Avoid the door frame from the ground too far, if the threshold is formed, it is not conducive to evacuation.

4、安装双扇门时要保证门扇贴合严密。

4. When installing the double door, ensure that the door leaf fits tightly.

5、不应自制门框，应购买正规的卷帘门扇进行安装。

5. Should not be self-made door frame, should buy regular rolling shutter door leaf to install.

6、卷帘门安装时应注意其是否具备良好的密闭性。

6. When the rolling shutter door is installed, attention should be paid to whether it has good airtightness.

7、坚决杜绝偷工减料，在安装时更好亲自把关。

7. It is necessary to put an end to shoddy work and materials, and better to personally check during installation.

三、管理到位，按时维护：济南卷帘门作为一种重要的消防设施和常用的防火分隔物在建筑中大量使用，其因保养不善、使用不当造成的损坏经常出现，所以要加强对它的管理和维护。

3、 Management in place, timely maintenance: Jinan rolling shutter door as an important fire-fighting facilities and commonly used fire-proof partition is widely used in buildings, and its damage caused by improper maintenance and improper use often occurs, so it is necessary to strengthen its management and maintenance.

1、杜绝在疏散走道上、防烟楼梯间前室或合用前室设置的常闭式卷帘门在使用过程中人为地使其常开，成为“常开”卷帘门，一旦发生火灾，这样的“常开”卷帘门起不到阻挡烟雾和防火的作用。

1. It is forbidden to make the normally closed rolling shutter door set on the evacuation corridor, the front room of smoke proof staircase or shared front room artificially make it normally open in the process of use, and become "normally open" rolling shutter door. In case of fire, such "normally open" rolling shutter door can not play a role in blocking smoke and fire prevention.

2、经常检查卷帘门的完好性，查看闭门器、顺序器是否好用，卷帘门能否按顺序自行关闭，铰链、合页上的螺丝是否松动，如有损坏应立即组织进行维修。

2. Regularly 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 close automatically in sequence, whether the screws on the hinge and hinge are loose, and if there is any damage, repair should be organized immediately.

3、杜绝使用单位片面追求装饰效果，将卷帘门门框取消而仅设置普通木材制作的门套，将门扇的原有边框换成其他材料，大范围加贴装饰面层，从而破坏防火涂层，起不到防火效果。

3. It is forbidden for the user to pursue the decorative effect unilaterally, cancel the door frame of the rolling shutter door and only set the door pocket made of ordinary wood, replace the original frame of the door leaf with other materials, and paste the decorative surface layer on a large scale, so as to destroy the fire-proof coating and have no fire-proof effect.

4、对常开式卷帘门要定期进行测试，检查其自行关闭控制系统、闭门器、顺序器、释放开关等方面是否好用，是否能在火灾发生时切实地起到自行关闭的功能，同时要坚决防止在常开式济南卷帘门旁随意堆放物品。

4. The normally open rolling shutter door should be tested regularly to check whether its self closing control system, door closer, sequencer, release switch and other aspects are easy to use, whether it can effectively play the function of self closing in case of fire, and at the same time, it is necessary to firmly prevent the random stacking of articles near the normally opened Jinan rolling shutter door.
