, the quality of Jinan roller shutter door has shrunk. The design and constituent materials of roller shutter door are unqualified. 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:

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 type selection: maintenance designers shall design targeted rolling shutter doors from the nature and type of different buildings. During the design, rolling shutter doors shall be reasonably set in strict accordance with the requirements of fire technical specifications, and the grade of rolling shutter doors shall 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 shall be considered that the distance between the rolling shutter door and the ceiling shall not be less than 500mm as far as possible, so that in case of fire accident, it can effectively prevent smoke from entering the staircase during personnel evacuation and ensure the smoke prevention effect of the staircase.

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 staircase and its front room with positive pressure air supply system, the matching of single leaf opening area and positive pressure air supply volume shall be considered. If the opening area is too large, the positive pressure air supply system in the staircase may not open smoothly due to the effect of wind pressure in case of fire, which is not conducive to rapid evacuation.

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 is large and the use frequency is high, the design of normally open rolling shutter door shall be given priority. Since the normally open type has the function of self closing by relying on the electromagnetic release valve or magnetic door suction, door closer and automatic control system, it can close quickly when a fire occurs, and play 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.

二、安装规范，质量把关：在安装济南卷帘门时，须选用合格的产品，不得降低等级并应严格按照规范进行安装

2、 Installation specification and quality control: when installing Jinan roller shutter door, qualified products must be selected, the grade shall not be reduced, and the installation shall be carried out 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 leaf, it shall be opened 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 blocking.

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

4、安装双扇门时要保证门扇贴合严密。

4. When installing double doors, ensure that the door leaves fit tightly.

5、不应自制门框，应购买正规的卷帘门扇进行安装。

5. The door frame shall not be self-made, but the formal rolling shutter door leaf shall be purchased for installation.

6、卷帘门安装时应注意其是否具备良好的密闭性。

6. When installing the rolling shutter door, pay attention to whether it has good tightness.

7、坚决杜绝偷工减料，在安装时更好亲自把关。

7. We will resolutely put an end to shoddy work and materials, and better 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 and maintenance on time: Jinan rolling shutter door is widely used in buildings as an important fire-fighting facility and common fire partition. Its damage caused by poor maintenance and improper use often occurs, so its management and maintenance should be strengthened.

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. The normally closed rolling shutter door set on the evacuation walkway, the front room of the smoke proof staircase or the shared front room shall not be artificially opened to become a "normally open" rolling shutter door in the process of use. In case of fire, such a "normally open" rolling shutter door can not block 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. 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 by itself in sequence, and whether the screws on the hinges and hinges are loose. If they are damaged, they shall be repaired 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. Put an end to the user's one-sided pursuit of decorative effect, cancel the door frame of rolling shutter door and only set the door pocket made of ordinary wood, replace the original frame of door leaf with other materials, and paste 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 shall be tested regularly to check whether its self closing control system, door closer, sequencer, release switch, etc. are easy to use, and whether it can effectively close itself in case of fire. At the same time, it is necessary to resolutely prevent random stacking of articles next to the normally open rolling shutter door.
