    卷簾門存在的六大問題

    發布人:http://www.fsaoling.com    發布時間:2021-11-24 20:04:45

    防火卷簾門是一種適用于建筑物大開孔的防火保溫設施。該產品在設計和安裝中起到一定的作用。防火卷簾門廣泛應用于工業和民用建筑的防火分區,能防止火災蔓延,確保生命財產。它是現代建筑中不可缺少的消防設施。以下是濟南防火卷簾門行業六大問題的分析。
    Fireproof rolling shutter door is a kind of fireproof and thermal insulation facility suitable for large openings in buildings. The product plays a certain role in design and installation. Fireproof rolling shutter door is widely used in the fire compartment of industrial and civil buildings, which can prevent the spread of fire and ensure life and property. It is an indispensable fire-fighting facility in modern buildings. The following is the analysis of six problems in Jinan fireproof rolling shutter door industry.
    一、防火卷簾門簾體厚度
    1、 Thickness of fireproof rolling shutter door curtain body
    門簾厚度為門簾所用鋼板的厚度。目前,偷工減料現象普遍存在。一些制造商在送去測試時使用較厚鋼板的窗簾板。在獲得合格證后,他們使用較薄的產品進行生產。由于安裝現場卷簾門的卷簾板厚度不易測量,容易蒙混過關,許多防火卷簾門由于卷簾的厚度而達不到要求,降低了使用壽命和耐火時限。
    The thickness of the door curtain is the thickness of the steel plate used for the door curtain. At present, the phenomenon of Jerry building is widespread. Some manufacturers use thicker steel curtain panels when sending them for testing. After obtaining the certificate, they use thinner products for production. Because the thickness of the rolling 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 can not meet the requirements due to the thickness of the rolling shutter, which reduces the service life and fire resistance time limit.
    二、防火卷簾門過梁結構
    2、 Lintel structure of fireproof rolling shutter door
    過梁結構:根據國家標準,防火卷簾門需要設置過梁結構。目前,無過梁防火卷簾門被廣泛使用,在發生火災時無法防止火勢向上的強烈沖擊,導致煙氣通過過梁向外擴散。過梁的密封性是防火防煙的關鍵。如果安裝無過梁結構的防火卷簾門,就不能起到防火屏障的作用,是徒勞的。
    Lintel structure: according to national standards, lintel structure shall be set for fireproof rolling shutter door. At present, lintel free fireproof rolling shutter doors are widely used, which can not prevent the strong upward impact of the fire in case of fire, resulting in the outward diffusion of smoke through the lintel. The sealing of lintel is the key to fire and smoke prevention. If the fire rolling shutter door without lintel structure is installed, it can not play the role of fire barrier, which is futile.
    三、防火卷簾門的導軌
    3、 Guide rail of fireproof rolling shutter door
    導軌存在的問題是導軌深不夠,結構和材料不當。這些是許多大型卷簾門安裝中常見的問題。大型卷簾門的導軌一般應具有能承受高強度的主要部件。然而,許多制造商使用簡單的輕型導軌來取代它。發生火災時,門簾很容易從導軌上脫落,不能起到防火作用。
    The problem with the guide rail is that the guide rail is not deep enough and the structure and material are improper. These are common problems in the installation of many large rolling shutter doors. The guide rail of large rolling shutter door shall generally have main components that can bear high strength. However, many manufacturers use simple lightweight guide rails to replace it. In case of fire, the door curtain is easy to fall off from the guide rail and cannot play the role of fire prevention.
    四、防火卷簾門底簾
    4、 Fireproof rolling shutter door bottom curtain
    卷簾門門檻問題有些產品沒有門檻,有些產品有門檻,但材料很薄。門簾底梁是保持門簾強度的重要構件。如果門簾下沒有底梁,則意味著門簾下部的實心框架較少,火災負壓將翻轉整個門簾。
    Roller shutter door threshold problem some products do not have a threshold, some products have a threshold, but the material is very thin. The bottom beam of the door curtain is an important component to maintain the strength of the door curtain. If there is no sill under the door curtain, it means that there are fewer solid frames at the lower part of the door curtain, and the fire negative pressure will overturn the whole door curtain.
    五、防火卷簾門傳動裝置的強度
    5、 Strength of transmission device of fireproof rolling shutter door
    防火卷簾軸傳動裝置的強度也是卷簾門的一個重要參數。目前,有很多產品強度不合格,嚴重影響防火卷簾門的使用。卷簾軸的結構主要是卷簾軸兩端軸頭插入鋼管的深和結構。軸頭堵頭深約為軸長的1/10,應有兩個法蘭和足夠的焊縫。一些制造商的產品填充很短,甚至帶有法蘭。這扇劣質的門使用一段時間后有被打破的危險。
    The strength of the shaft transmission device of the fireproof rolling shutter is also an important parameter of the rolling shutter door. At present, the strength of many products is unqualified, which seriously affects the use of fireproof rolling shutter doors. The structure of the roller shutter shaft is mainly the depth and structure in which the shaft heads at both ends of the roller shutter shaft are inserted into the steel pipe. The depth of shaft head plug is about 1 / 10 of the shaft length, and there shall be two flanges and sufficient welds. Some manufacturers have products with short filling and even flanges. This inferior door is in danger of being broken after a period of use.
    六、防火卷簾門手動控制的傳動問題
    6、 Transmission problem of manual control of fireproof rolling shutter door
    停電時手動快關裝置的傳動問題為火災。當電源中斷時,現場人員可使用手動快速釋放裝置關門。目前,一些防火卷簾門未配備該裝置。即使安裝了,也常常因為質量問題而無法工作。
    In case of power failure, the transmission problem of manual quick closing device is fire. When the power supply is interrupted, the field personnel can use the manual quick release device to close the door. At present, some fireproof rolling shutter doors are not equipped with this device. Even if installed, it often fails to work due to quality problems.
