    鋼制防火卷簾門

    Steel fireproof rolling shutter door

    防火卷簾門導軌問題,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。鋼制防火卷簾的底簾問題,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。

    The problems with the guide rails of fireproof rolling shutter doors, such as insufficient depth of the guide rails, improper structure and materials, are common problems in the installation of many large rolling shutter doors. There should generally be a main component on the guide rail of a large rolling shutter door that can withstand high strength. However, many factories use simple lightweight guide rails as a substitute. In the event of a fire, the door curtain is prone to detach from the guide rails, which fails to provide fire protection. The problem with the bottom curtain of steel fireproof rolling shutters, and the problem with the bottom beam of rolling shutter doors. Some products do not have a bottom beam, while others have a bottom beam but use thin materials. The bottom beam of the door curtain is an important component to maintain its strength. Without a bottom beam under the door curtain, it is equivalent to a lack of a sturdy frame at the bottom of the door curtain. The negative pressure in the fire will flip the entire door curtain.

    鋼制防火卷簾的手動控制的傳動問題,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在有一部分鋼制防火卷簾沒裝這種裝置。即使裝了,也往往因質量問題,不起作用。

    The transmission problem of manual control for steel fireproof rolling shutter, and the transmission problem of manual quick closing device in case of power failure during fire. If there is a power outage, on-site personnel can use a manual quick release device. Close the door. Some steel fireproof rolling shutters are not equipped with this device now. Even if installed, it often does not work due to quality issues.

    鋼制防火卷簾門楣結構問題:門楣結構問題按國家標準鋼制防火卷簾必須設置門楣結構,而目前普遍使用的是沒有門楣的鋼制防火卷簾,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鋼制防火卷簾,則不能真正起到防火阻隔的作用,形同虛設。

    Structural problem of steel fireproof rolling shutter door lintel: According to national standards, steel fireproof rolling shutter must be equipped with a lintel structure. Currently, steel fireproof rolling shutter without a lintel is commonly used, and this type of door cannot prevent the strong impact of the fire from rising in the event of a fire. Causing smoke to spread outward through the lintel. The sealing of the door lintel is the key to fire and smoke prevention. If a steel fireproof rolling shutter without a door lintel structure is installed, it cannot truly serve as a fire barrier and is virtually non-existent.

    鋼制防火卷簾傳動裝置強度問題,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,嚴重影響了鋼制防火卷簾的使用。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 for steel fireproof rolling shutters is an important parameter for rolling shutter doors. Currently, there are many products with substandard strength, which seriously affects the use of steel fireproof rolling shutters. 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 inserted into the steel pipe. The depth of the shaft head plug should be about 1/10 of the shaft length, and there should be two flanges and sufficient welds. Some manufacturers have products that are inserted very short, even using a flange. These shoddy doors are at risk of breaking after being used for a period of time.

    鋼制防火卷簾簾體厚度問題: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,有很多鋼制防火卷簾因門簾厚度都未達到要求,降低使用壽命與耐火時限。

    The thickness issue of the steel fireproof rolling shutter body: The thickness of the door curtain refers to the thickness of the steel plate used for the curtain panel. Currently, there is a common phenomenon of cutting corners and materials. Some manufacturers use thicker steel plate curtain panels for testing, and after obtaining a certificate of conformity, they switch to thinner ones for production. Due to the difficulty in measuring the thickness of the curtain panel for rolling shutter doors during installation, it is easy to deceive. Therefore, many steel fireproof rolling shutters have reduced service life and fire resistance time due to the thickness of the door curtain not meeting the requirements.
