在镀锌风管施工过程中,有以下几个要点需求特别留心下:

During the construction of galvanized air duct, the following points need special attention:

1、镀锌风管道穿墙时应用不燃保温材料封堵如岩棉。

1. When galvanized air pipeline passes through the wall, it should be sealed with non-combustible insulation material such as rock wool.

2、镀锌风管道装置时其内应边装置边穿尼龙线,以便于严密性检测时拖动行灯检测,严密性检测前应准备150W安全行灯与至少50米电线。

2。 When galvanized air pipeline is installed, it should be equipped with nylon wires at the inner edge, so as to drive the street lamp for tightness testing。 Before tightness testing, 150W safety street lamp and at least 50m wire should be prepared。

3、编号时应注明体系名称层别、序号、断面标准、每节长度等。

3. When numbering, the system name level, serial number, section standard and length of each section should be indicated.

4、支吊架装置时胀大栓孔深度为胀大螺栓导管长度加1~1.5CM .

4. The depth of expansion bolt hole in support and suspension device is 1~1.5CM for the length of expansion bolt conduit.

5、支架及镀锌风管道装置时应拉线装置,以便于装置结束调整直线度与平面度。镀锌风管道吊杆应垂直,同一标准镀锌风管道的吊杆应在一条长度方向直线上。

5。 When bracket and galvanized air duct are installed, wire drawing device should be used to adjust straightness and flatness at the end of the installation。 The hanger of galvanized air pipeline should be vertical, and the hanger of the same standard galvanized air pipeline should be in a straight line in the length direction。

6、管道装置调直后应就法兰连接部位重新用阻燃密封胶密封。

6. Flame-retardant sealant should be re-used to seal the flange joint after straightening the pipeline device.

7、吊杆与托架联接时固定螺母托架上部一个、下部两个,并加防振橡胶垫厚10MM ,以防镀锌管道振动时螺母松动。

7。 When the suspender is connected with the bracket, the upper part and the lower part of the fixed nut bracket are two, and the thickness of the anti-vibration rubber pad is 10MM, so as to prevent the nut from loosening when the galvanized pipeline vibrates。

8、较长的管道有高差变化时,应在低处应根据客观实际情况设置接水盘,并有水封。

8。 When the height difference of a long pipeline varies, the water receiving pan and water seal should be set in the lower part according to the objective reality。

9、直径或长边大于630MM的风阀处应独自设置支吊架,风阀方向应正确,防火阀距墙不得大于200MM.

9。 The support and hanger should be installed alone at the air valve with diameter or long side greater than 630MM。 The direction of the air valve should be correct, and the distance between the fire valve and the wall should not be greater than 200MM。

10、镀锌风管道穿越防火卷帘及防火墙时应设置防护导管,导管厚度不得小于1.6MM,导管与镀锌风管道间用不燃保温材料封堵(如岩棉)。

10. When galvanized air pipeline passes through fire curtains and firewalls, protective ducts shall be installed. The thickness of ducts shall not be less than 1.6MM. The ducts and galvanized air pipelines shall be sealed with non-combustible insulation materials (such as rock wool).
