在鍍鋅風(fēng)管施工過程中，有以下幾個(gè)要點(diǎn)需求特別留心下：

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

1、鍍鋅風(fēng)管道穿墻時(shí)應(yīng)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(fēng)管道裝置時(shí)其內(nèi)應(yīng)邊裝置邊穿尼龍線，以便于嚴(yán)密性檢測時(shí)拖動(dòng)行燈檢測，嚴(yán)密性檢測前應(yīng)準(zhǔn)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(shí)應(yīng)注明體系名稱層別、序號、斷面標(biāo)準(zhǔn)、每節(jié)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(shí)脹大栓孔深度為脹大螺栓導(dǎo)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(fēng)管道裝置時(shí)應(yīng)拉線裝置，以便于裝置結(jié)束調(diào)整直線度與平面度。鍍鋅風(fēng)管道吊桿應(yīng)垂直，同一標(biāo)準(zhǔn)鍍鋅風(fēng)管道的吊桿應(yīng)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(diào)直后應(yīng)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(lián)接時(shí)固定螺母托架上部一個(gè)、下部兩個(gè)，并加防振橡膠墊厚10MM ,以防鍍鋅管道振動(dòng)時(shí)螺母松動(dòng)。

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(shí)，應(yīng)在低處應(yīng)根據(jù)客觀實(shí)際情況設(shè)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(fēng)閥處應(yīng)獨(dú)自設(shè)置支吊架，風(fēng)閥方向應(yīng)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(fēng)管道穿越防火卷簾及防火墻時(shí)應(yīng)設(shè)置防護(hù)導(dǎo)管，導(dǎo)管厚度不得小于1.6MM,導(dǎo)管與鍍鋅風(fēng)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).
