在鍍鋅風管施工過程中，有以下幾個要點需求特別留心下：

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

1、鍍鋅風管道穿墻時應用不燃保溫材料封堵如巖棉。

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

2、鍍鋅風管道裝置時其內應邊裝置邊穿尼龍線，以便于嚴密性檢測時拖動行燈檢測，嚴密性檢測前應準備150W行燈與少50米電線。

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、編號時應注明體系名稱層別、序號、斷面標準、每節長度等。

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

4、支吊架裝置時脹大栓孔深度為脹大螺栓導管長度加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、支架及鍍鋅風管道裝置時應拉線裝置，以便于裝置結束調整直線度與平面度。鍍鋅風管道吊桿應垂直，同一標準鍍鋅風管道的吊桿應在一條長度方向直線上。

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、管道裝置調直后應就法蘭連接部位重新用阻燃密封膠密封。

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

7、吊桿與托架聯接時固定螺母托架上部一個、下部兩個，并加防振橡膠墊厚10MM ,以防鍍鋅管道振動時螺母松動。

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、較長的管道有高差變化時，應在低處應根據客觀實際情況設置接水盤，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、直徑或長邊大于630MM的風閥處應獨自設置支吊架，風閥方向應正確，防火閥距墻不得大于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、鍍鋅風管道穿越防火卷簾及防火墻時應設置防護導管，導管厚度不得小于1.6MM,導管與鍍鋅風管道間用不燃保溫材料封堵(如巖棉)。

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).
