1用防火卷帘代替防火墙的时候,其两侧应设置有水幕系统保护,或采用耐火极限不能小于3.Oh的复合形防火卷帘。设在疏散走道和前室的防火卷帘,应具有在降落时有短时间停滞以及能从两侧手动控制的功能,以保障人员安全疏散;应具有自动、手动和机械控制的功能。这些在防火卷帘门的厂家也有销售。
1 when the fire shutter is used to replace the firewall, water curtain system protection shall be set on both sides, or composite fire shutter with fire resistance limit not less than 3.oh shall be used. The fire rolling shutter set in the evacuation walkway and front room shall have the function of short-time stagnation during landing and manual control from both sides, so as to ensure the safe evacuation of personnel; It shall have the functions of automatic, manual and mechanical control. These are also sold by manufacturers of fireproof rolling shutter doors.
2为保证火灾初起时人员的安全疏散及消防人员顺利扑救火灾,防火卷帘应有一定的启闭速度。防火卷帘的自动启动探测器,或易熔环日扣应在墙的两面安装(一个靠近洞口的顶部安装,另一个在墙两侧的顶棚上或靠近顶棚处安装),并和卷帘的开关联系起来,这样任何一个探头或易熔环的动作,都将使卷帘关闭。
2. In order to ensure the safe evacuation of personnel at the beginning of a fire and the smooth fire fighting of firefighters, the fire shutter shall have a certain opening and closing speed. The automatic start detector or fusible ring day buckle of the fireproof rolling shutter shall be installed on both sides of the wall (one shall be installed on the top near the hole, and the other shall be installed on or near the ceiling on both sides of the wall), and shall be connected with the switch of the rolling shutter, so that the action of any probe or fusible ring will close the rolling shutter.
3导轨应留有足够间隙,以保证受火作用时导轨在垂直方向上可发生一定的膨胀变形。安装在边框之间的导轨可以外露也可以在凹处暗装。防火卷帘的自动启闭机构应用金属外壳封闭,以保证不受损坏和在火灾时能正常运转。
3. Sufficient clearance shall be reserved for the guide rail to ensure that the guide rail can expand and deform in the vertical direction under the action of fire. The guide rail installed between the frames can be exposed or concealed in the recess. The automatic opening and closing mechanism of the fire shutter shall be closed with a metal shell to ensure that it will not be damaged and can operate normally in case of fire.
4一般每一橙防火卷帘设置两套控制卷门机的电器按钮,即门洞内外各一套,按钮要启动操纵灵活、可靠。对于集中控制和联动控制的动作要灵敏准确。自动控制的保险装置应安装在卷帘附近2米范围内的暴露部分及随时能监控的部分;自动控制的电源、备用电源应能保证正常工作状态,所用的电器线路不允许裸露应埋人墙内或有穿管。
4. Generally, each orange fire shutter shall be equipped with two sets of electrical buttons to control the door rolling machine, that is, one set inside and outside the door opening. The buttons shall be started and operated flexibly and reliably. The actions of centralized control and linkage control shall be sensitive and accurate. The automatically controlled safety device shall be installed in the exposed part within 2m around the roller shutter and the part that can be monitored at any time; The automatic control power supply and standby power supply shall be able to ensure the normal working state. The electrical circuits used shall not be exposed and shall be buried in the wall or through pipes.
