浅谈防火卷帘门都需要注意些什么问题

防火卷帘门是一种适用于建筑物较大洞口处的防火、隔热设施，产品在设计安装上起到了一定的作用技术。下面济南防火卷帘门安装维修人员为您讲解下防火卷帘门都需要注意些什么问题。

Fireproof rolling shutter door is a fire prevention and thermal insulation facility applicable to large openings in buildings. The product plays a certain role in design and installation. Next, the installation and maintenance personnel of Jinan fire shutter door will explain to you what problems should be paid attention to.

1、防火卷帘门门楣结构问题

1. Structural problems of lintel of fireproof rolling shutter door

门楣结构问题按国家标准防火卷帘门必须设置门楣结构，而现在遍及运用的是没有门楣的防火卷帘门，这种门发生火灾时阻止不了火势向上形成的强大冲击.导致烟气经过门楣向外延伸。门楣处的密封性是防火、防烟的关键所在，若装置没有门楣结构的防火卷帘门，则不能真正起到防火隔绝的效果，形同虚设。

The lintel structure must be set for the fireproof rolling shutter door according to the national standard, but now the fireproof rolling shutter door without lintel is widely used. This kind of door can not prevent the strong impact of the fire upward in case of fire, resulting in the smoke extending outward through the lintel. The tightness of the lintel is the key to fire prevention and smoke prevention. If the fire shutter door without the lintel structure is installed, it can not really play the role of fire insulation, and it is a virtual thing.

2、防火卷帘门帘体厚度问题

2. Thickness of fire shutter

门帘厚度问题门帘厚度即帘板所用钢板的厚度，现在遍及存在着偷工减料现象，有些厂家送交测试时选用较厚钢板的帘板，获得合格证后，则改用较薄的进行出产。由于在装置现场卷帘门的帘板厚度不易丈量，简单蒙混过关，因而，有许多防火卷帘门因门帘厚度都未达到要求，降低运用寿命与耐火时限。

The thickness of the door curtain is the thickness of the steel plate used for the curtain plate. Now there is a phenomenon of cutting corners. Some manufacturers choose thicker steel plate for the curtain plate when sending it for testing. After obtaining the certificate of conformity, they use thinner steel plate for production. Due to the fact that the thickness of the shutter of the rolling shutter door at the installation site is not easy to measure, and it is easy to muddle through, there are many fireproof rolling shutter doors that have not met the requirements due to the thickness of the curtain, reducing the service life and fire resistance time limit.

3、防火卷帘门的底帘问题

3. The problem of bottom curtain of fireproof rolling shutter door

卷帘门底梁问题有的产品没有底梁，有的产品虽有底梁，但用料单薄。门帘的底梁是坚持门帘强度重要构件，门帘下没有底梁就等于门帘下部少一个起坚固效果的边框，火场负压就会将整个门帘掀翻。

The problem of roller shutter door sill Some products have no sill, and some products have sill, but the materials are thin. The bottom beam of the door curtain is an important component to adhere to the strength of the door curtain. If there is no bottom beam under the door curtain, it is equal to the lack of a solid frame under the door curtain, and the negative pressure of the fire will overturn the whole door curtain.

4、防火卷帘门导轨问题

4. The guide rail of fire shutter door

导轨问题导轨深度不行，结构与用料不当是许多大型卷帘门装置中遍及存在的问题。大型卷帘门导轨上一般应有一根能承受高强度的主构件.但是许多厂商用简易的轻型导轨来替代，一旦遇到火灾，门帘易从导轨脱出，起不到防火效果。

The problem of the guide rail is that the depth of the guide rail is not good, and the structure and material are improper. Generally, there should be a main component that can bear high strength on the guide rail of large roller shutter door. However, many factories use simple light guide rail to replace it. In case of fire, the door curtain is easy to come out of the guide rail, which can not play a fire prevention effect.

5、防火卷帘门的手动控制的传动问题

5. Transmission problem of manual control of fire shutter door

断电时手动快速封闭装置的传动问题火灾中。如发生电源中止，现场人员可选用手动速放装置.将门封闭。现在有一部分防火卷帘门没装这种装置。即使装了，也往往因质量问题，不起效果。

The transmission problem of the manual fast closing device in case of power failure is in fire. In case of power interruption, the on-site personnel can select the manual quick-release device to close the door. At present, some fireproof rolling shutter doors are not equipped with such devices. Even if it is installed, it is often ineffective due to quality problems.

6、防火卷帘门传动装置强度问题

6. The strength of the driving device of the fireproof rolling shutter door

防火卷帘轴的传动装置强度也是卷帘门的一个重要参数，现在这种强度不合格的产品许多，严重影响了防火卷帘门的运用。卷帘轴的结构主要指卷帘轴两头轴头塞人钢管内的深度及其结构。轴头塞人深度应为轴长的1/10左右，且要有两个法兰和足够的焊缝。

The strength of the transmission device of the fireproof roller shutter shaft is also an important parameter of the roller shutter door. Now there are many unqualified products with this strength, which seriously affects the use of the fireproof roller shutter door. The structure of the roller shutter shaft mainly refers to the depth and structure of the two ends of the roller shutter shaft stuffed into the steel pipe. The plug depth of the shaft head should be about 1/10 of the shaft length, and there should be two flanges and enough welds.

有些厂商的产品却塞入很短，乃至用一个法兰，这种偷工减料的门运用一段时间后有断裂的危险。

Some manufacturers' products are plugged in very short, even with a flange. This kind of shoddy door may break after being used for a period of time.
