防火卷帘门在建筑中能发挥多少作用?
2018-1-15 15:04:20
防火卷帘是一种重要的防火分隔物,它在一定时间内,连同框架能满足耐火稳定性和完整性要求的卷帘,由帘板、卷轴、电机、导轨、支架、防护罩和控制机构等组成。防火卷帘与防火墙或防火门等防火分隔物将各楼层在水平方向分隔出防火区域,可以有效地把火势控制在一定的范围内,减少火灾损失,同时可以为人员安全疏散、消防扑救提供有利的条件。
Fire shutter is an important fireproof partition. It can meet the requirements of fire stability and integrity within a certain time, which is composed of curtain, reel, motor, guide, bracket, protective cover and control mechanism. Fire shutter and firewall or fire door fire barrier will separate each floor area in the horizontal direction, can effectively put under control in a certain range, reducing the loss of fire, fire fighting and can provide favorable conditions for safe evacuation.
防火卷帘门已成高楼中的必需品。这些防火卷帘门是一种适用于建筑物较大洞口处的防火、隔热设施,产品在设计上采用了卷轴内藏的特点,具有结构合理紧凑。
The fire curtain door has become a necessity in the high building. These fire shutter doors are fireproof and heat insulation facilities for large openings of buildings. The products are designed with the characteristics of reel storage, and the structure is reasonable and compact.
防火卷帘门的帘面通过传动装置和控制系统达到卷帘的升降,起到防火、隔火作用,,产品外形平整美观、造型新颖,具有钢性强。防火卷帘门广泛应用于工业与民用建筑的防火隔断区,能有效地阻止火势蔓延,保障生命财产安全,是现代建筑中不可缺少的防火设施。

The curtain surface of the fire shutter door can achieve the lifting of the rolling curtain through the transmission device and the control system. It plays the role of fire protection and fire isolation, and the product is smooth and beautiful, with novel shape and strong steel quality. Fire shutter doors are widely used in the fire isolation area of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. It is an indispensable fire protection facilities in modern architecture.

当某一防火分区直线段需多台卷帘门分隔时,最好将三台以下作为一个部位对探测器进行编码,任何一对探测器接受到信号后,三档门同时下降。此时,只需一只联动控制盒控制其中一台卷帘门,而将其余几台卷帘门控制箱内的自动控制线,并联于联动控制盒直接控制的卷帘门控制箱内。如果同时启动的卷帘门超过三台,起动电流较大,中间继电器及主电源控制开关、导线都要相应加大,是很不经济的。同时,一组带的设备太多,故障点也多,难以及时排除。在某一防火分区直线段的一条防线上,分组下降是不会影响防火功能的。因为,烟雾的扩散速度很快,在第一组卷帘门下降后,如果火势未能控制住,烟雾会继续扩散到第二组卷帘门上空,使第二组感烟探测器动作,第二组卷帘门下降。卷帘门第二步下降到底的控制信号由相应部位的感温探测器控制。
When a fire line need multiple shutter doors separated, preferably below three units as a part of the detector is a detector of any encoding, the received signal, falling at the same time third door. At this time, only one linkage control box is required to control one rolling door, and the other automatic control lines in the control boxes of the rolling door control are directly connected to the control box of the rolling door control directly controlled by the linkage control box. If there are more than three rolling doors at the same time, the starting current is large, and the interte relay and main power control switch and conductor should be increased correspondingly, which is very uneconomical. At the same time, a group of equipment with a lot of equipment, more fault points, it is difficult to eliminate in time. In a line of fire division a line of defence, the fall of the group will not affect the fire protection function. Because the diffusion speed of smoke is very fast. If the fire fails to control the first group of shutter doors, the smoke will continue to spread to the second group of shutter doors, so that second groups of smoke detectors will move and the second rolling shutters will fall. The control signal of the two step down to the end of the shutter door is controlled by the sensor in the corresponding part.
