隨著社會的發(fā)展，防火卷簾已經(jīng)成為現(xiàn)代化建筑不可缺少的設(shè)備之一，但防火卷簾門還是存在著一些問題，下面濟南防火卷簾門安裝維修人員就針對這些問題來深入了解一下。

With the development of society, fire rolling shutter has become one of the indispensable equipment for modern buildings, but there are still some problems with fire rolling shutter doors. Now, the installation and maintenance personnel of fire rolling shutter doors in Jinan will have a deep understanding of these problems.

1、厚度問題：

1. Thickness problem:

門簾的厚度是用于門簾板的鋼板的厚度。目前，偷工減料的現(xiàn)象很普遍。一些制造商在送檢時使用較厚鋼板的窗簾板。獲得證書后，他們使用較薄的一種進行生產(chǎn)。由于卷簾的厚度不易測量，卷簾的使用壽命不易滿足現(xiàn)場卷簾的要求，所以卷簾不易現(xiàn)場安裝。

The thickness of the curtain is the thickness of the steel plate used for the curtain panel. At present, the phenomenon of cutting corners is very common. Some manufacturers use thicker steel curtain panels when submitting for inspection. After obtaining the certificate, they used the thinner one for production. Because the thickness of the roller shutter is not easy to measure, and the service life of the roller shutter is not easy to meet the requirements of the on-site roller shutter, it is not easy to install the roller shutter on site.

2、門楣結(jié)構(gòu)問題：

2. Lintel structure:

過梁結(jié)構(gòu)：根據(jù)標準，防火卷簾門應(yīng)設(shè)置過梁結(jié)構(gòu)。目前，無過梁防火卷簾門被廣泛使用，在火災(zāi)發(fā)生時無法防止火災(zāi)的強烈沖擊向上，使煙氣通過過梁向外擴散。過梁的緊密性是防火和防煙的關(guān)鍵。如果安裝了無過梁結(jié)構(gòu)的防火卷簾門，則不能起到防火屏障的作用。

Lintel structure: According to the national standard, the fireproof rolling shutter door shall be provided with a lintel structure. At present, lintel free fireproof rolling shutter doors are widely used, which can not prevent the strong impact of fire from rising when a fire occurs, making smoke spread outward through the lintel. The tightness of lintel is the key to fire and smoke prevention. If the fire rolling shutter door without lintel structure is installed, it cannot play the role of fire barrier.

3、導(dǎo)軌問題

3. Guide rail problem

導(dǎo)軌存在的問題是導(dǎo)軌深度不夠，結(jié)構(gòu)和材料不當。這些是許多大型卷簾門安裝中常見的問題。大型卷簾門的導(dǎo)軌應(yīng)具有能夠承受高強度的主要部件，然而，許多工廠使用簡單的輕型導(dǎo)軌來代替它。發(fā)生火災(zāi)時，門簾很容易從導(dǎo)軌上脫落，不能起到防火作用。

The problems of the guide rail are that the depth of the guide rail is not enough, and the structure and materials are improper. These are common problems in the installation of many large rolling shutter doors. The guide rail of large roller shutter door shall have the main parts that can withstand high strength. However, many factories use simple light guide rail to replace it. In case of fire, the door curtain is easy to fall off from the guide rail and cannot play a role in fire prevention.

4、底簾問題

4. Bottom curtain problem

防火卷簾門底梁問題有的產(chǎn)品沒有底梁，雖然有些產(chǎn)品有底梁，但使用的材料很薄。門簾底梁是保持門簾強度的重要構(gòu)件。如果門簾下沒有底梁，則意味著門簾下部的實心框架較少，火災(zāi)的負壓將翻轉(zhuǎn)整個門簾。

Some products have no sill, although some products have sill, the materials used are very thin. The bottom beam of the curtain is an important component to maintain the strength of the curtain. If there is no sill under the curtain, it means that there are fewer solid frames under the curtain, and the negative pressure of the fire will overturn the entire curtain.

5、傳動裝置強度問題

5. Drive strength problem

防火卷簾軸的傳動裝置強度也是卷簾門的一個重要參數(shù)，目前，有很多產(chǎn)品強度不合格，嚴重影響防火卷簾門的使用。卷簾軸的結(jié)構(gòu)主要是指卷簾軸兩端的軸頭插入鋼管的深度和結(jié)構(gòu)。軸頭堵頭深度約為軸長的1/10，應(yīng)有兩個法蘭和足夠的焊縫。一些制造商的產(chǎn)品填充很短，甚帶有法蘭。這扇劣質(zhì)的門使用一段時間后有被打破的危險。

The strength of the transmission device of the fireproof roller shutter shaft is also an important parameter of the roller shutter door. At present, there are many products whose strength is unqualified, which seriously affects the use of the fireproof roller shutter door. The structure of roller shutter shaft mainly refers to the depth and structure of the shaft heads at both ends of the roller shutter shaft inserted into the steel pipe. The depth of the shaft head plug is about 1/10 of the shaft length, and there should be two flanges and enough welds. Some manufacturers have products with short filling and even flanges. This inferior door is in danger of being broken after being used for some time.

6、的手動控制的傳動問題

6. Transmission problem of manual control of

斷電時手動快速關(guān)閉裝置的傳動問題火災(zāi)中。如果停電，現(xiàn)場人員可以使用手動快速釋放裝置關(guān)門。目前，一些防火卷簾門沒有配備這種裝置。即使安裝了，由于質(zhì)量問題，它通常也無法工作。

The transmission of the manual quick closing device in case of power failure is in fire. In case of power failure, on-site personnel can use manual quick release device to close the door. At present, some fire rolling doors are not equipped with such devices. Even if it is installed, it usually does not work due to quality problems.

以上就是不容忽視的六個問題，在卷簾門的發(fā)展過程中，只有不斷其存在的問題，才能更有效地保護我們。更多相關(guān)事項就來我們網(wǎng)站http://luoboyy.com進行咨詢！
