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、濟南防火卷簾門楣結構問題：按照標準，防火卷簾門楣結構要建立。現在普遍使用無門楣的防火卷簾門。一旦發生火災，火勢的強大沖擊力并無法阻止。煙霧可以通過門楣蔓延。門楣的氣密性是防火、防煙的關鍵，安裝沒有楣結構的防火卷簾門，起不到防火墻的作用。

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、防火卷簾門手動控制的傳動問題，停電時手動送合閘裝置的傳動。出現火災時，現場人員可以在停電時使用手動快速釋放裝置。將門關閉，有些防火卷簾門沒有配備這種裝置。有的還有質量問題，即使安裝它也常常效率低下。

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、防火卷簾門的傳動裝置強度防火卷簾軸的傳動裝置強度也是卷簾門的一個重要參數。目前，有很多產品強度不合適，嚴重影響防火卷簾門的使用。

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、濟南防火卷簾門的導軌問題導軌的問題不夠，結構和材料不當是安裝很多大型卷簾門的通病。一般來說，大型卷簾門的導軌要有能夠承受高強度的主要部件。但是很多廠家都用簡單的光導軌來代替，一旦發生火災，窗簾很容易從導軌上脫落，無法防止火災。

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、濟南防火卷簾門簾體的厚度：門簾的厚度門簾的厚度是門簾板所用鋼板的厚度。目前普遍存在截肢現象。一些制造商在提交測試時使用較厚的板。我們改用更薄的生產。卷簾門卷簾板的厚度在安裝現場不易測量，容易混淆，所以門簾的厚度不符合要求，因此很多防火卷簾門未達到使用標準，就降低了壽命和耐火時間限制。

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、防火卷簾門地簾問題。有的產品沒有地梁，有的產品有地梁，但材質較薄。門簾下梁是保持門簾強度的重要組成部分。門簾下沒有底梁意味著門簾底部有一個非剛性框架，一旦有大型火場，火勢會掀翻整個門簾。

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.
