防火卷簾門是一種適用于建筑物較大洞口處的防火、隔熱設(shè)施，產(chǎn)品在設(shè)計安裝上起到了一定的作用技術(shù)。下面濟(jì)南防火卷簾門安裝維修人員為您講解下防火卷簾門都需要注意些什么問題。

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、防火卷簾門門楣結(jié)構(gòu)問題

1. Structural problems of lintel of fireproof rolling shutter door

門楣結(jié)構(gòu)問題按標(biāo)準(zhǔn)防火卷簾門必須設(shè)置門楣結(jié)構(gòu)，而現(xiàn)在遍及運(yùn)用的是沒有門楣的防火卷簾門，這種門發(fā)生火災(zāi)時阻止不了火勢向上形成的強(qiáng)大沖擊.導(dǎo)致煙氣經(jīng)過門楣向外延伸。門楣處的密封性是防火、防煙的關(guān)鍵所在，若裝置沒有門楣結(jié)構(gòu)的防火卷簾門，則不能真正起到防火隔絕的效果，形同虛設(shè)。

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、防火卷簾門簾體厚度問題

2. Thickness of fire shutter

門簾厚度問題門簾厚度即簾板所用鋼板的厚度，現(xiàn)在遍及存在著偷工減料現(xiàn)象，有些廠家送交測試時選用較厚鋼板的簾板，獲得合格證后，則改用較薄的進(jìn)行出產(chǎn)。由于在裝置現(xiàn)場卷簾門的簾板厚度不易丈量，簡單蒙混過關(guān)，因而，有許多防火卷簾門因門簾厚度都未達(dá)到要求，降低運(yùn)用壽命與耐火時限。

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、防火卷簾門的底簾問題

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

卷簾門底梁問題有的產(chǎn)品沒有底梁，有的產(chǎn)品雖有底梁，但用料單薄。門簾的底梁是堅持門簾強(qiáng)度重要構(gòu)件，門簾下沒有底梁就等于門簾下部少一個起堅固效果的邊框，火場負(fù)壓就會將整個門簾掀翻。

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、防火卷簾門導(dǎo)軌問題

4. The guide rail of fire shutter door

導(dǎo)軌問題導(dǎo)軌深度不行，結(jié)構(gòu)與用料不當(dāng)是許多大型卷簾門裝置中遍及存在的問題。大型卷簾門導(dǎo)軌上一般應(yīng)有一根能承受高強(qiáng)度的主構(gòu)件.但是許多廠商用簡易的輕型導(dǎo)軌來替代，一旦遇到火災(zāi)，門簾易從導(dǎo)軌脫出，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、防火卷簾門的手動控制的傳動問題

5. Transmission problem of manual control of fire shutter door

斷電時手動快速封閉裝置的傳動問題火災(zāi)中。如發(fā)生電源中止，現(xiàn)場人員可選用手動速放裝置.將門封閉。現(xiàn)在有一部分防火卷簾門沒裝這種裝置。即使裝了，也往往因質(zhì)量問題，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、防火卷簾門傳動裝置強(qiáng)度問題

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

防火卷簾軸的傳動裝置強(qiáng)度也是卷簾門的一個重要參數(shù)，現(xiàn)在這種強(qiáng)度不合格的產(chǎn)品許多，嚴(yán)重影響了防火卷簾門的運(yùn)用。卷簾軸的結(jié)構(gòu)主要指卷簾軸兩頭軸頭塞人鋼管內(nèi)的深度及其結(jié)構(gòu)。軸頭塞人深度應(yīng)為軸長的1/10左右，且要有兩個法蘭和足夠的焊縫。

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.

有些廠商的產(chǎn)品卻塞入很短，乃用一個法蘭，這種偷工減料的門運(yùn)用一段時間后有斷裂的危險。

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.

防火卷簾門廣泛應(yīng)用于工業(yè)與民用建筑的防火隔斷區(qū)，能有效地阻止火勢蔓延，保障生命財產(chǎn)，是現(xiàn)代建筑中不可缺少的防火設(shè)施。您對此有需求就來我們網(wǎng)站http://luoboyy.com咨詢！
