            防火卷簾門使用期間常有六個問題要明確

            來源:http://www.shaulmediation.com 日期:2022-07-05 發布人:hongshun
            防火卷簾門廣泛應用于工業與民用建筑的防火隔斷區,能有效地阻止火勢蔓延,保障生命財產安全,是現代建筑中不可缺少的防火設施。防火卷簾門使用期間常有六個問題要明確!
            Fire shutter door is widely used in the fire partition area of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. It is an indispensable fire prevention facility in modern buildings. There are often six problems to be clarified during the use of fire shutter doors!
            一、防火卷簾門簾體厚度問題:
            1、 The thickness of fire shutter door curtain body:
            門簾厚度問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象,有些廠家送交測試時采用較厚鋼板的簾板,取得合格證后,則改用較薄的進行生產。由于在安裝現場卷簾門的簾板厚度不易測量,容易蒙混過關,因此,有很多防火卷簾門因門簾厚度都未達到要求,降低使用壽命與耐火時限。
            The thickness of the door curtain is the thickness of the steel plate used for the curtain plate. At present, there is a widespread phenomenon of cutting corners. Some manufacturers send curtain plates with thicker steel plates for testing. After obtaining the certificate of conformity, they use thinner ones for production. Because the thickness of the shutter plate of the rolling shutter door on the installation site is difficult to measure and easy to muddle through, many fire-proof rolling shutter doors have not met the requirements because of the thickness of the shutter, reducing the service life and fire resistance time limit.
            二、防火卷簾門門楣結構問題:
            2、 The lintel structure of fire shutter door:
            門楣結構問題按國家標準防火卷簾門必須設置門楣結構,而目前普遍使用的是沒有門楣的防火卷簾門,這種門發生火災時阻止不了火勢向上形成的強大沖擊.導致煙氣通過門楣向外蔓延。門楣處的密封性是防火、防煙的關鍵所在,若安裝沒有門楣結構的防火卷簾門,則不能真正起到防火阻隔的作用,形同虛設。
            Lintel structure problem according to the national standard, the fire-proof rolling shutter door must be equipped with a lintel structure. At present, the fire-proof rolling shutter door without a lintel is widely used. This kind of door cannot prevent the strong impact of the upward fire in case of a fire, resulting in the smoke spreading outward through the lintel. The tightness of the lintel is the key to fire and smoke prevention. If the fire shutter door without the lintel structure is installed, it cannot really play the role of fire barrier and is in vain.
            三、防火卷簾門導軌問題
            3、 Problems of guide rail of fire shutter door
            導軌問題導軌深度不夠,結構與用料不當是許多大型卷簾門安裝中普遍存在的問題。大型卷簾門導軌上一般應有一根能承受高強度的主構件.然而很多廠商用簡易的輕型導軌來代替,一旦遇到火災,門簾易從導軌脫出,起不到防火作用。
            Guide rail problem the insufficient depth of guide rail and improper structure and materials are common problems in the installation of many large roller shutter doors. Generally, there should be a main component on the guide rail of large roller shutter door that can bear high strength. However, many manufacturers use simple light guide rail to replace it. In case of fire, the door curtain is easy to fall out of the guide rail and cannot play the role of fire prevention.

            四、防火卷簾門的底簾問題
            4、 The problem of the bottom curtain of the fireproof rolling shutter door
            卷簾門底梁問題有的產品沒有底梁,有的產品雖有底梁,但用料單薄。門簾的底梁是保持門簾強度重要構件,門簾下沒有底梁就等于門簾下部少一個起堅固作用的邊框,火場負壓就會將整個門簾掀翻。
            Roller shutter door sill problem some products do not have a sill, some products have a sill, but the material is thin. The bottom beam of the door curtain is an important component to maintain the strength of the door curtain. If there is no bottom beam under the door curtain, it means that there is less a solid frame under the door curtain, and the negative pressure of the fire will overturn the whole door curtain.
            五、防火卷簾門傳動裝置強度問題
            5、 Strength problem of transmission device of fire shutter door
            防火卷簾軸的傳動裝置強度也是卷簾門的一個重要參數,目前這種強度不合格的產品很多,嚴重影響了防火卷簾門的使用。卷簾軸的結構主要指卷簾軸兩端軸頭塞人鋼管內的深度及其結構。軸頭塞人深度應為軸長的1/10左右,且要有兩個法蘭和足夠的焊縫。有些廠商的產品卻塞入很短,甚至用一個法蘭,這種偷工減料的門使用一段時間后有斷裂的危險。
            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 with unqualified strength, 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 plugged 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. Some manufacturers' products are stuffed for a short time, and even use a flange. Such Jerry built doors are in danger of breaking after being used for a period of time.
            六、防火卷簾門的手動控制的傳動問題
            6、 Transmission problem of manual control of fire shutter door
            濟南卷簾門廠提醒您,斷電時手動快速關閉裝置的傳動問題火災中。如發生電源中斷,現場人員可采用手動速放裝置.將門關閉?,F在有一部分防火卷簾門沒裝這種裝置。即使裝了,也往往因質量問題,不起作用。
            Jinan rolling shutter door factory reminds you that the transmission problem of the manual quick closing device in case of power failure is in the fire. In case of power interruption, field personnel can use manual quick release device to close the door. At present, some fireproof rolling shutter doors are not equipped with such devices. Even if installed, it often doesn't work because of quality problems.
