    防火门安装注意事项

    作者:浙江多麦福网址:www.duomaifu.com人气:发表时间:2017-04-25 10:23

      钢质防火是门一类以冷轧钢板为主要原料,通过冷加工而且具有的防火防盗功能的产品,钢质防火门的防火防盗功能一方面来源于其本身原料以及生产技术,而另一方面则与其装置质量有着密不可分的联系。设计人员应从不同建筑的性质、类型上设计有针对性的防火门,在设计时要严格按照消防技术规范要求,合理设置防火门,不得随意降低防火门的等级。下面我们就来和济南防火门厂家了解一下钢质防火应该如何安装:

      Steel fire prevention is a kind of cold rolled steel sheet as the main raw material, through the cold working and has a certain function of fire alarm products, steel fire door of fire alarm function on the one hand, from its raw material and production technology, on the other hand, the quality of the intimate contact with device. Designers from different construction on the nature and types of design targeted fire door, when the design must be strictly in accordance with the requirements for fire fighting technical specification, reasonable setting fire door, not to reduce the level of the fire door. Below, we will come to know how the steel fire prevention should be installed:

      1、安装钢质防火门时先要确定洞口尺度,使洞口尺度大于钢质防火门框尺度,好依照规范需求进行装置.然后将钢质防火门全体装入洞口尺度内,并做好暂时定位的安全措施,避免钢质防火门全体倾倒,门框附近缝隙以泥砂浆为准,门框和固守时有必要结实牢靠。

      1 when installing steel fire door, must first determine the hole dimension, the hole length scales is greater than steel fire doors, best in accordance with the specification requirements of device. And then the steel fire door all into the mouth of the cave scale, safety measures and make a temporary location, to avoid all the dumping of steel fire door, door frame near the gap will be subject to clay mortar, frame and stick to it necessary to strong.

      2、安装钢质防火门时扇与门框搭接不得小于10mm,扇与门框之间的两边缝隙不得大于4mm.防火门装置完闭之后的缝隙不能过大,不然防火门的密闭功能难以确保,也难以表现其在火灾条件下按捺火灾及烟气延伸效果,因而,防火门的留缝宽度要严格控制。

      2 when installing steel fire door, door and door frame lap should not be less than 10 mm, on either side of the gap between fan and door frames shall not be greater than 4 mm. The fire door device after closed the gap not too big, otherwise difficult to ensure that fire door airtight function, also expressed its hard under the condition of fire raging fire and smoke extension effect, therefore, the fire door seam width to be strictly controlled.

      3、钢质防火门在装置过程中,考虑到门框的曲折变形这个问题,要在门框宽度方向用木枋支撑起来,门框下脚埋入地面下20mm,再将门框与墙体上的预埋件焊接,然后在门框上角的墙上开洞,灌注混凝土。

      3, steel fire door in the process of device, considering the winding deformation of frame this problem, to use wood in the frame width direction fang support, doorcase waste into 20 mm under the ground, and the embedded parts on the door frame and wall body welding, and then on the door frame Angle of open hole in the wall, pouring concrete.

      4、门框附近浇水泥砂浆时,注意少填多搅、灌满、灌实,边灌砂浆边调整待全部砂浆灌溉完后,应结实牢靠,禁再移动防火门。维护期不得低于48小时,冬季不低于72小时,待砂浆完全干后,方可开、关钢质防火门,并查看各部的空隙,若还有装置不到位的细节,需求作出调整。

      4, near the door frame pouring cement mortar, pay attention to the less fill more stirring, filling, filling, filling and mortar while after the adjustment for all mortar irrigation, should be strong, banning mobile fire door again. Maintenance period shall not be less than 48 hours, winter not less than 72 hours, after being dry mortar, steel fire door can open and close and departments, and see if there are the details of the device is not in place, needs to adjust.

      5、钢质防火门装置好后,依据状况装置闭门器,调整启闭是不是灵活紧密的,开关门时平稳无较为明显的碰击现象。

      After, steel fire door device, according to the condition of device door closers, adjust the opening and closing flexible is tight, no more obvious impact on the smooth open and closing phenomenon.

      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。由于常开式防火门有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的功 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。以上就是防火门厂家总结的关于钢质防火的安装事项,建议您在挑选防火时好挑选规范的品牌公司进行采办,自己也仍然能够运用如上的一些知识对装置工人的装置质量进行查验。

      In the construction, the area where the daily traffic is more frequently and the fire door USES more frequently, should consider the design often open fire door. Due to often open fire door by electromagnetic relief valve or magnetic door stopper, door closers, and automatic control system to realize the autistic can work, 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. Above is the fire door manufacturer summary about the installation of steel fire prevention, suggest you had better choose when choosing fire brand company procurement specification, oneself also can still use some knowledge of the above device for quality inspection of plant workers.
