買一個(gè)好的卷簾門很重要，但是后期卷簾門的使用也同樣的重要，不當(dāng)?shù)牟僮鲿?huì)使卷簾門受到損壞。下面濟(jì)南卷簾門廠家來(lái)講講關(guān)于防火卷簾門部件的三大常見(jiàn)問(wèn)題。

It is important to buy a good roller shutter door, but the use of roller shutter door in the later stage is also important. Improper operation will damage the roller shutter door. Next, Jinan roller shutter door manufacturer will talk about three common problems about fire shutter door components.

防火卷簾門簾體厚度問(wèn)題：門簾厚度問(wèn)題門簾厚度即簾板所用鋼板的厚度，目前普遍存在著偷工減料現(xiàn)象，有些廠家送交測(cè)試時(shí)采用較厚鋼板的簾板，取得合格證后，則改用較薄的進(jìn)行生產(chǎn)。由于在安裝現(xiàn)場(chǎng)卷簾門的簾板厚度不易測(cè)量，容易蒙混過(guò)關(guān)，因此，有很多防火卷簾門因門簾厚度都未達(dá)到要求，降低使用壽命與耐火時(shí)限。鋼質(zhì)特技防火卷簾門

The thickness of the fire resisting roller shutter: the thickness of the shutter is the thickness of the steel plate used for the shutter. At present, there is a widespread phenomenon of jerry built. Some manufacturers use thicker steel plates for testing. After obtaining the certificate, they use thinner ones for production. Because the thickness of the shutter of the rolling shutter door is not easy to measure at the installation site, it is easy to muddle through. Therefore, many fireproof rolling shutter doors have lower service life and fire resistance time limit because the thickness of the shutter does not meet the requirements. Steel special fireproof rolling shutter door

防火卷簾門門楣結(jié)構(gòu)問(wèn)題：門楣結(jié)構(gòu)問(wèn)題按標(biāo)準(zhǔn)防火卷簾門須設(shè)置門楣結(jié)構(gòu)，而目前普遍使用的是沒(méi)有門楣的防火卷簾門，這種門發(fā)生火災(zāi)時(shí)阻止不了火勢(shì)向上形成的強(qiáng)大沖擊．導(dǎo)致煙氣通過(guò)門楣向外蔓延。門楣處的密封性是防火、防煙的關(guān)鍵所在，若安裝沒(méi)有門楣結(jié)構(gòu)的防火卷簾門，則不能起到防火阻隔的作用，形同虛設(shè)。

The lintel structure of the fire rolling shutter door: the lintel structure of the fire rolling shutter door shall be set according to the national standard. At present, the fire rolling shutter door without lintel is widely used, which can not prevent the strong impact of the fire when a fire occurs, causing smoke to spread outward through the lintel. The sealing at the lintel is the key to fire and smoke prevention. If a fire rolling shutter door without lintel structure is installed, it cannot play the role of fire prevention and separation, and it is just a figment.

防火卷簾門傳動(dòng)裝置強(qiáng)度問(wèn)題：防火卷簾軸的傳動(dòng)裝置強(qiáng)度也是卷簾門的一個(gè)重要參數(shù)，目前這種強(qiáng)度不合格的產(chǎn)品很多，嚴(yán)重影響了防火卷簾門的使用。卷簾軸的結(jié)構(gòu)主要指卷簾軸兩端軸頭塞人鋼管內(nèi)的深度及其結(jié)構(gòu)。軸頭塞人深度應(yīng)為軸長(zhǎng)的1／10左右，且要有兩個(gè)法蘭和足夠的焊縫。有些廠商的產(chǎn)品卻塞入很短，甚用一個(gè)法蘭，這種偷工減料的門使用一段時(shí)間后有斷裂的危險(xiǎn)。

The strength of the transmission device of the fire shutter door: The strength of the transmission device of the fire shutter shaft is also an important parameter of the fire shutter door. At present, there are many products with unqualified strength, which seriously affects the use of the fire shutter door. The structure of the roller shutter shaft mainly refers to the depth and structure of the shaft heads at both ends of the roller shutter shaft plugged into the steel pipe. The insertion depth of shaft head shall be about 1/10 of the shaft length, and there shall be two flanges and enough welds. Some manufacturers' products are stuffed very short, even with a flange. This kind of jerry built door may break after being used for a period of time.

此外要注意，斷電時(shí)手動(dòng)快速關(guān)閉裝置的傳動(dòng)問(wèn)題火災(zāi)中。如發(fā)生電源中斷，現(xiàn)場(chǎng)人員可采用手動(dòng)速放裝置．將門關(guān)閉?，F(xiàn)在有一部分防火卷簾門沒(méi)裝這種裝置。即使裝了，也往往因質(zhì)量問(wèn)題，不起作用，所以在選擇卷簾門時(shí)要多考慮購(gòu)買，更多相關(guān)事項(xiàng)就來(lái)我們網(wǎng)站http://ifxf.cn咨詢吧！

In addition, it should be noted that when the power is cut off, the transmission of the manual quick closing device is in fire. In case of power interruption, on-site personnel can use manual quick release device to close the door. At present, some fire rolling shutter doors are not equipped with such devices. Even if it is installed, it often does not work because of quality problems, so you should consider purchasing more when choosing roller shutter doors, and more relevant matters will come to our website http://ifxf.cn Consult!
