安装济南济南卷帘门的必要原因分析

　　Analysis of the necessary reasons for installing Jinan roller shutter doors in Jinan

　　济南卷帘门大轴安装前，先将挂板定好方向装到卷轴上，再把4-6片帘板装到挂板上并卷紧在卷轴上川铁丝扎牢。吊装济南卷帘门大轴，一定要注意，设专人指挥、人字梯、脚手架、手拉葫芦都要经过检查。装置时先将套上轴承及座的光轴塞入卷轴端孔中，对准位置后将轴承固定螺栓拧紧。3卷轴上好后，可左右移动卷筒调节位置。同时用水平尺和水平管复核一下卷轴的水平。防火电机在装置前先在支架上链轮上先套上链条，固定驱动底座前，把链条套到小链轮上，然后旋紧固定螺栓，这时抖动链条能使卷轴转动。济南卷帘门的装置过程一定要在工程人员的参与下完成安装，或都请相关济南卷帘门公司装置，以防装置不合格而引发的灾难和损失。

　　Before installing the main shaft of the Jinan rolling shutter door, first set the direction of the hanging plate and install it onto the scroll. Then, install 4-6 curtain plates onto the hanging plate and tighten them onto the scroll with steel wire to secure them. When hoisting the roller shutter door shaft in Jinan, safety must be taken into account, and a dedicated person must be assigned to command. The zigzag ladder, scaffolding, and chain block must all be inspected. When installing the device, first insert the optical axis of the bearing and seat into the end hole of the reel, align the position, and then tighten the bearing fixing bolts. After the 3-reel is installed, the position of the reel can be adjusted by moving it left and right. At the same time, use a level ruler and a level tube to double check the levelness of the scroll. Before installing the fireproof motor, first put a chain on the sprocket of the bracket. Before fixing the drive base, put the chain on the small sprocket and tighten the fixing bolt. At this time, shaking the chain can make the reel rotate. The installation process of Jinan rolling shutter doors must be completed with the participation of professional engineering personnel or with the assistance of relevant professional Jinan rolling shutter door companies to prevent disasters and losses caused by unqualified installation.

　　目前市场上许多不合格防火门未设置防火密封条，或者密封条不平直、拱起，并无检测机构出具的合格检测报告。有的用普通木质线条替代防火密封条，当火灾发生时不但不会膨胀封堵孔隙，甚会影响防火门的耐火、隔烟与隔热性。有些在钢质防火门安装的防火玻璃，无合格检测报告，厚度达不到要求，有些将耐火极限为0.6h的防火玻璃安装在防火门上，甚将普通玻璃替代防火玻璃使用。 被检不合格的钢制防火门部分无产品标志、质量检验合格标志和质量认证（认可）合格标志。产品外观不完整，有破损，表面不净光，有刨痕、毛刺和锤印，割角、拼缝不严实平整等。

　　At present, many unqualified fire doors on the market are not equipped with fire sealing strips, or the sealing strips are not straight or arched, and there is no qualified testing report issued by national testing institutions. Some use ordinary wooden strips instead of fireproof sealing strips. When a fire occurs, it not only does not expand and seal the pores, but also affects the fire resistance, smoke insulation, and thermal insulation of the fireproof door. Some fire-resistant glass installed on steel fire doors do not have qualified testing reports and do not meet the required thickness. Some install fire-resistant glass with a fire resistance limit of 0.6 hours on Class A fire doors, and even replace fire-resistant glass with ordinary glass. The steel fire doors that failed the inspection do not have product marks, quality inspection marks, and quality certification (approval) marks. The appearance of the product is incomplete, with damage, an uneven surface, scratches, burrs, and hammer marks, as well as loose corners and uneven seams.
