济南防火卷帘门常见的六个问题

Jinan fireproof rolling shutter door is a kind of fireproof and thermal insulation facilities suitable for large-scale construction places. The product has played a certain role in design and installation. It is widely used in the fire partition area of industrial and civil buildings. It can well prevent the spread of fire. It is an indispensable fire prevention facility in modern buildings. But there are six problems about it that can't be underestimated. Let's have a look.

1、济南防火卷帘门楣结构问题：按照国家标准，防火卷帘门楣结构要建立。现在普遍使用无门楣的防火卷帘门。一旦发生火灾，火势的强大冲击力并无法阻止。烟雾可以通过门楣蔓延。门楣的气密性是防火、防烟的关键，安装没有楣结构的防火卷帘门，起不到防火墙的作用。

1. Jinan fire shutter lintel structure: according to the national standard, the fire shutter lintel structure should be established. Nowadays, fire rolling shutter doors without lintels are widely used. In case of fire, the powerful impact of the fire cannot be stopped. Smoke can spread through the lintel. The air tightness of the lintel is the key to fire and smoke prevention. The installation of fire rolling shutter door without lintel structure can not play the role of firewall.

2、防火卷帘门手动控制的传动问题，停电时手动送合闸装置的传动。出现火灾时，现场人员可以在停电时使用手动快速释放装置。将门关闭，有些防火卷帘门没有配备这种装置。有的还有质量问题，即使安装它也常常效率低下。

2. The transmission problem of manual control of fireproof rolling shutter door is the transmission of manual closing device in case of power failure. In case of fire, field personnel can use manual quick release device in case of power failure. Close the door. Some fireproof rolling shutter doors are not equipped with this device. Some have quality problems, and even installing it is often inefficient.

3、防火卷帘门的传动装置强度防火卷帘轴的传动装置强度也是卷帘门的一个重要参数。目前，有很多产品强度不合适，严重影响防火卷帘门的使用。

3. The strength of the transmission device of the fireproof rolling shutter door and the strength of the transmission device of the fireproof rolling shutter shaft is also an important parameter of the rolling shutter door. At present, the strength of many products is inappropriate, which seriously affects the use of fireproof rolling shutter doors.

4、济南防火卷帘门的导轨问题导轨的问题不够，结构和材料不当是安装很多大型卷帘门的通病。一般来说，大型卷帘门的导轨要有能够承受高强度的主要部件。但是很多厂家都用简单的光导轨来代替，一旦发生火灾，窗帘很容易从导轨上脱落，无法防止火灾。

4. The problem of guide rail of Jinan fireproof rolling shutter door, the problem of insufficient guide rail and improper structure and materials are common problems in the installation of many large rolling shutter doors. Generally speaking, the guide rail of large rolling shutter door should have main components that can bear high strength. However, many manufacturers use simple light guide rail instead. In case of fire, the curtain is easy to fall off from the guide rail and can not prevent fire.

5、济南防火卷帘门帘体的厚度：门帘的厚度门帘的厚度是门帘板所用钢板的厚度。目前普遍存在截肢现象。一些制造商在提交测试时使用较厚的板。我们改用更薄的生产。卷帘门卷帘板的厚度在安装现场不易测量，容易混淆，所以门帘的厚度不符合要求，因此很多防火卷帘门未达到使用标准，就降低了寿命和耐火时间限制。

5. Thickness of Jinan fireproof rolling shutter door curtain body: the thickness of the door curtain is the thickness of the steel plate used for the door curtain plate. Amputation is a common phenomenon at present. Some manufacturers use thicker plates when submitting tests. We switched to thinner production. The thickness of the rolling shutter plate of the rolling shutter door is difficult to measure and easy to be confused at the installation site, so the thickness of the door curtain does not meet the requirements. Therefore, many fireproof rolling shutter doors do not meet the service standard, which reduces the service life and fire resistance time limit.

6、防火卷帘门地帘问题。有的产品没有地梁，有的产品有地梁，但材质较薄。门帘下梁是保持门帘强度的重要组成部分。门帘下没有底梁意味着门帘底部有一个非刚性框架，一旦有大型火场，火势会掀翻整个门帘。

6. Fireproof rolling shutter door ground curtain problem. Some products do not have floor beams, and some products have floor beams, but the material is thin. The lower beam of the door curtain is an important part to maintain the strength of the door curtain. There is no sill under the curtain, which means that there is a non rigid frame at the bottom of the curtain. Once there is a large fire, the fire will overturn the whole curtain.
