卷帘门存在的六大问题

发布人:http://www.kdjlm.com    发布时间:2021-11-24 20:04:45

防火卷帘门是一种适用于建筑物大开孔的防火保温设施。该产品在设计和安装中起到一定的作用。防火卷帘门广泛应用于工业和民用建筑的防火分区,能防止火灾蔓延,确保生命财产。它是现代建筑中不可缺少的消防设施。以下是济南防火卷帘门行业六大问题的分析。
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、防火卷帘门帘体厚度
1、 Thickness of fireproof rolling shutter door curtain body
门帘厚度为门帘所用钢板的厚度。目前,偷工减料现象普遍存在。一些制造商在送去测试时使用较厚钢板的窗帘板。在获得合格证后,他们使用较薄的产品进行生产。由于安装现场卷帘门的卷帘板厚度不易测量,容易蒙混过关,许多防火卷帘门由于卷帘的厚度而达不到要求,降低了使用寿命和耐火时限。
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、防火卷帘门过梁结构
2、 Lintel structure of fireproof rolling shutter door
过梁结构:根据国家标准,防火卷帘门需要设置过梁结构。目前,无过梁防火卷帘门被广泛使用,在发生火灾时无法防止火势向上的强烈冲击,导致烟气通过过梁向外扩散。过梁的密封性是防火防烟的关键。如果安装无过梁结构的防火卷帘门,就不能起到防火屏障的作用,是徒劳的。
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、防火卷帘门的导轨
3、 Guide rail of fireproof rolling shutter door
导轨存在的问题是导轨深不够,结构和材料不当。这些是许多大型卷帘门安装中常见的问题。大型卷帘门的导轨一般应具有能承受高强度的主要部件。然而,许多制造商使用简单的轻型导轨来取代它。发生火灾时,门帘很容易从导轨上脱落,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、防火卷帘门底帘
4、 Fireproof rolling shutter door bottom curtain
卷帘门门槛问题有些产品没有门槛,有些产品有门槛,但材料很薄。门帘底梁是保持门帘强度的重要构件。如果门帘下没有底梁,则意味着门帘下部的实心框架较少,火灾负压将翻转整个门帘。
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、防火卷帘门传动装置的强度
5、 Strength of transmission device of fireproof rolling shutter door
防火卷帘轴传动装置的强度也是卷帘门的一个重要参数。目前,有很多产品强度不合格,严重影响防火卷帘门的使用。卷帘轴的结构主要是卷帘轴两端轴头插入钢管的深和结构。轴头堵头深约为轴长的1/10,应有两个法兰和足够的焊缝。一些制造商的产品填充很短,甚至带有法兰。这扇劣质的门使用一段时间后有被打破的危险。
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、防火卷帘门手动控制的传动问题
6、 Transmission problem of manual control of fireproof rolling shutter door
停电时手动快关装置的传动问题为火灾。当电源中断时,现场人员可使用手动快速释放装置关门。目前,一些防火卷帘门未配备该装置。即使安装了,也常常因为质量问题而无法工作。
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.
