卷帘门维修过程中要注意避免什么问题?

来源:http://www.jnhsjlm.com 日期:2023-01-12 发布人:
在选择维修卷帘门的时候,定要谨慎,目前而言,卷帘门大存在着几个面的问题,下面济南卷帘门厂为您进行分析。
Be careful when choosing to repair the roller shutter door. At present, there are several problems with the roller shutter door. Now Jinan Roller shutter door factory will analyze for you.
1。卷帘门门帘厚度问题:门帘厚度卷帘板所用钢板的厚度,目前普遍存在着偷工减料现象,有些厂家送交测试时采用较厚钢板的帘板,取得合格证后,则改用较薄的进行生产。由于在安装现场卷帘门的帘板厚度不易测量,容易蒙混,因此,有卷帘门因门帘厚度都未要求,低使用寿命与耐火时限。
1。 The problem of the thickness of the shutter door: the thickness of the steel plate used for the shutter plate is the thickness of the shutter door. At present, there is a widespread phenomenon of jerry-building. Some manufacturers use the thicker steel plate for the shutter plate when sending it for testing. After obtaining the certificate of conformity, they use the thinner steel plate for production. Because the thickness of the shutter of the roller shutter door at the installation site is difficult to measure and easy to be confused, there are roller shutter doors with low service life and fire resistance time limit because the thickness of the shutter is not required.
2。卷帘门预卷问题:按常规当门帘放到底时,上部在帘轴应留1圈门帘,以减少门帘量对螺钉处的拉力。块帘板破裂。但现在的卷帘门普遍没有做到这1点。由于帘卷都在顶里面,验收时无法觉察,使用时间久后有整帘掉下的危险。
2。 Pre-rolling problem of rolling shutter door: according to the convention, when the curtain is put to the bottom, the upper part of the curtain should be left with a circle of curtain on the curtain shaft to reduce the tension of the curtain on the screw. A curtain is broken. However, the current rolling shutter doors generally fail to do this. Because the curtain roll is in the top, it cannot be detected during acceptance, and there is a risk that the whole curtain will fall down after a long time of use.

3。卷帘门门楣结构问题:卷帘门维修按标准卷帘门须设置门楣结构,门楣处的密封性是防火、防烟的关键所在,若安装没有门楣结构的卷帘门,则真z起到防火的作用,形同虚设。而目前普遍使用的是没有门楣的卷帘门,这种门发生火灾时阻止不了火势向上形成的大冲击。导烟气通过门楣向外蔓延。
3。 The problem of the lintel structure of the roller shutter door: the roller shutter door must be equipped with a lintel structure for maintenance according to the standard. The tightness of the lintel is the key to fire prevention and smoke prevention. If the roller shutter door without a lintel structure is installed, it will play the role of fire prevention, and it is a virtual thing. At present, the rolling shutter door without lintel is widely used. This kind of door can not prevent the big impact of the fire when it is in fire. The flue gas spreads outward through the lintel.
4。卷帘门门帘底梁问题:有的产品没有底梁,有的产品虽有底梁,但用料单薄。门帘的底梁是保持门帘度要构件,门帘下没有底梁等于门帘下部少1个起作用的边框,火场负压将整个门帘掀翻。
4。 The problem of the sill of the roller shutter door curtain: some products have no sill, and some products have sill, but the materials are thin. The bottom beam of the door curtain is the key component to maintain the door curtain. The absence of the bottom beam under the door curtain is equal to the lack of one functional frame under the door curtain. The negative pressure of the fire field will overturn the whole door curtain.
5。卷帘门导轨问题:导轨s度不够,结构与用料不当是许多大型卷帘门安装中普遍存在的问题。大型卷帘门导轨上1般应有1根能承受高度的主构件。然而厂商用简易的轻型导轨来代替,一旦遇到火灾,门帘易从导轨脱出,起不到防火作用。
5。 The problem of roller shutter door guide rail: the S degree of the guide rail is not enough, and the structure and material are improper, which are common problems in the installation of many large roller shutter doors. Generally, there should be one main component capable of bearing height on the guide rail of large roller shutter door. However, the factory uses simple light guide rail to replace it. In case of fire, the door curtain is easy to come out of the guide rail and cannot play the role of fire prevention.
