    在不同的地方需要安装不同类型的防火卷帘门,合理设置防火门,且不得随意降低防火门的等级。应根据建筑性质、类型,严格按照消防技术规范要求。
    Need to be installed in different places of the different types of fire shutter, setting up reasonable fire door, and shall not be arbitrarily reduce the level of the fire door. Should according to the nature of construction, type, in strict accordance with the fire fighting technical specification requirements.
           在建筑内日常人流量较多、防火门使用频率较大的部位,应优先考虑设计常开式防火门。常开式防火门其功能主要靠电磁释放阀或磁力门吸、闭门器及自动控制系统来实现自闭功能,在火灾发生时能够自行迅速关闭,起到防止火灾蔓延和烟气扩散的作用,这样设计既有利于在火灾发生时人员疏散,又能避免防火门经常使用而出现的损坏。
    In daily traffic building more fire door use frequency in large part, priority should be given to the design often open fire door. Often open fire door its function mainly by electromagnetic relief valve or magnetic door stopper, door closers, and automatic control system to implement the self-closing function, when the fire can quickly close on its own, stop the spread of the spread of fire and smoke, can be designed so that when the fire evacuation, and can avoid damage by fire doors are often used.
           在设计封闭楼梯间和未采用正压送风系统防烟楼梯间前室的防火门时,应考虑防火门距顶棚的距离尽量不小于500mm,这样一旦发生火灾事故,可以有效防止人员疏散时烟气进入楼梯间内,可保证楼梯间的防烟效果。
    In the design of stair, closed and adopt positive pressure air supply system before the smoke prevention stair room fire door, fire door should be considered from the ceiling of the distance as far as possible not less than 500 mm, so in case of fire accident, can effectively prevent the evacuation when the flue gas into the stairwell, guaranteeing the smoke prevention of staircase effect.
           在济南卷帘门设计有正压送风系统楼梯间及其前室的防火门时,应考虑到防火门的单扇开启面积与正压送风量相匹配。如果防火门开启面积过大,在火灾发生时,楼梯间内正压送风系统运行的情况下由于风压的作用,可能会造成防火门开启不够顺畅,不利于人员迅速疏散。
    In jinan book door stair design has positive pressure air supply system and its front room fire door, open the fire door should be considered single area match the positive pressure air output. If fire door open area is too large, when the fire broke out, the stair inside under the condition of positive pressure air supply system is a result of the action of wind pressure, may cause fire door open is not smooth, does not favor the staff quickly evacuated.
