济南卷帘门维修的时候,经常会遇到几个问题,这就需要大家要多了解,下面就一起来了解下卷帘门大致存在着几个方面的问题。
Jinan roller shutter door maintenance, often encounter several problems, which requires us to understand more, the following together to understand the next roller shutter door there are some problems.
1、卷帘门门帘厚度问题:门帘厚度即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,容易蒙混过关,因此,有很多卷帘门因门帘厚度都未达到要求,降低使用寿命与耐火时限。
1. The thickness of rolling shutter door curtain: the thickness of the curtain is the thickness of the steel plate used for the curtain plate. At present, there is a phenomenon of Jerry building. Some manufacturers use the thicker steel plate curtain plate when they send it for testing. After obtaining the certificate of conformity, they use the thinner one for production. Because the thickness of the curtain plate of the rolling shutter door on the installation site is not easy to measure, it is easy to muddle through. Therefore, there are many rolling shutter doors because of the curtain The thickness does not meet the requirements, reducing the service life and fire resistance time.
2、卷帘门预卷问题:按常规当门帘放到底时,上部在帘轴应留一圈门帘,以减少门帘重量对螺钉处的拉力,防止一块帘板破裂,但现在的卷帘门普遍没有做到这一点,由于帘卷都在吊顶里面,验收时无法觉察,使用时间久后有整帘掉下的危险,后患无穷。
2. Pre rolling problem of rolling shutter door: according to the routine, when the curtain is placed to the end, a circle of curtain shall be reserved on the upper part of the curtain shaft to reduce the tension of the weight of the curtain on the screw and prevent the rupture of a curtain plate. However, the rolling shutter door generally fails to do this at present, because the curtain rolls are all in the ceiling, which cannot be detected during the acceptance, there is a risk that the whole curtain will fall down after a long time of use, and there will be endless troubles.

3、卷帘门门楣结构问题:济南卷帘门按国家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,则不能起到防火阻隔的作用,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强大冲击,导致烟气通过门楣向外蔓延。
3. Structural problems of the lintel of roller shutter door: according to the national standard, the lintel structure must be set in Jinan roller shutter door. The sealing of the lintel is the key to fire prevention and smoke prevention. If the roller shutter door without lintel structure is installed, it can't play the role of fire prevention and barrier. It's like a virtual device. At present, the roller shutter door without lintel is widely used, which can't prevent the fire direction in case of fire The strong impact formed on the top causes the smoke to spread outwards 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强度重要构件,门帘下没有底梁就等于门帘下部少一个起坚固作用的边框,火场负压就会将整个门帘掀翻。
4. The problem of bottom beam of roller shutter door curtain: some products have no bottom beam, while some products have a bottom beam, but the material is thin. The bottom beam of the curtain is an important component to maintain the strength of the curtain. If there is no bottom beam under the curtain, it means that there is less a solid frame under the curtain, and the negative pressure of the fire will overturn the whole curtain.
5、卷帘门导轨问题:导轨深度不够,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,大型卷帘门导轨上一般应有一根能承受高强度的主构件,然而很多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 rolling shutter door guide rail: insufficient depth of guide rail, improper structure and material are common problems in the installation of many large rolling shutter doors. Generally, there should be a main component that can bear high strength on the guide rail of large rolling shutter doors. However, many factories use simple light guide rail to replace it. Once a fire occurs, the curtain is easy to get out of the guide rail, which does not play a role in fire prevention.
6、卷帘门卷帘轴的强度问题:卷帘轴强度也是卷帘门的一个重要参数,目前这种强度不合格的产品很多,严重影响了卷帘门的使用,卷帘轴的结构主要指卷帘轴两端轴头塞人钢管内的深度及其结构,轴头塞人深度应为轴长的1/10左右,且要有两个法兰和足够的焊缝,有些厂商的产品却塞入很短,甚至用一个法兰,这种偷工减料的门使用一段时间后有断裂的危险。
6. Strength of roller shutter shaft: the strength of roller shutter shaft is also an important parameter of roller shutter door. At present, there are many unqualified products, which seriously affect the use of roller shutter door. The structure of roller shutter shaft mainly refers to the depth and structure of the shaft plug at both ends of the roller shutter shaft into the steel pipe. The shaft plug depth should be about 1 / 10 of the shaft length, and there should be two flanges and enough welds , some manufacturers' products are stuffed in a short time, even with a flange. This kind of door with Jerry built materials may break after being used for a period of time.
7、济南卷帘门传动链条问题:传动链条一般由卷门机制造厂按卷门机的提升重量生产,并随卷门机一同配来,目前一些卷门窗幕墙帘门所配链条普遍嫌小,卷帘 门都存在着断裂的可能,按常规标准,卷帘门应当有断链安.全装置,而实际上许多门没有这方面的装置,因而存在不安.全的隐卷帘门患。
7. Jinan rolling shutter door drive chain problem: the drive chain is generally produced by the rolling machine manufacturer according to the lifting weight of the rolling machine, and is matched with the rolling machine. At present, the chain of some rolling doors, windows, curtain walls, curtain doors is generally too small According to the conventional standard, the rolling shutter door should have the safety device of broken chain. In fact, many doors do not have such a device, so there is a problem of uneasy and safe hidden rolling shutter door.

8、卷帘门轴承、轴承架与卷门机的问题:卷帘轴、轴承架与卷门机的安装不规范,不统一,大部分制造卷帘门的工厂没有正规的图纸,没有正规的技术工人,也是一个急待解决的问题。
8. The problems of roller shutter bearing, bearing frame and rolling machine: the installation of roller shutter shaft, bearing frame and rolling machine is not standardized and unified. Most of the factories that manufacture roller shutter do not have regular drawings and technical workers, which is also an urgent problem to be solved.
9、卷帘门断电时手动快速关闭装置的传动问题:火灾中,如发生电源中断,现场人员可采用手动速放装置,将门关闭,现在有一部分卷帘门没装这种装置,即使装了,也往往因质量问题,不起作用。
9. Transmission problem of the manual quick closing device when the rolling shutter door is powered off: in case of power interruption in the fire, the field personnel can use the manual quick release device to close the door. Now some rolling shutter doors are not equipped with this device, even if it is installed, it often fails to work due to quality problems.
10、卷帘门火灾温度控制关门问题:国标规定,在卷帘门2米范围内,当火灾发生,电源中断,现场无人操作时,应当有火势温度熔断控制关门装置,这个功能特别对人员密集场所更显重要,但现在尚不见这类装置。
10. Shutter door fire temperature control door closing problem: according to the national standard, when the fire occurs, the power supply is interrupted, and no one is operating on site, there should be a fire temperature fuse control door closing device. This function is particularly important for densely populated places, but such devices are not yet available.
目前市场上塑料异型材产量虽然很大,济南卷帘门但有一个共同点,即均为白色,色调单一,不能适应建筑墙面装饰多样化的要求。
At present, although the output of plastic profile in the market is very large, Jinan roller shutter door has one thing in common, that is, they are all white with single color, which can not meet the requirements of diversified wall decoration.
