As for the construction, we pay great attention to it. Here is a brief introduction of the preparation before the construction.

　　關于比擬復雜的民用建筑，在設計階段，各工種（暖通、給水排水，供電照明與濟南螺旋風管加工）應協商好空間分隔，定出每種管道的標高范圍。普通狀況下不得越出給本人規則的界線。遇有個別管段要越界時應與其他工程協商。

　　In the design stage of a comparatively complex civil building, each type of work (HVAC, water supply and drainage, power supply and lighting, and processing of Jinan spiral duct) should first negotiate space separation and determine the elevation range of each type of pipeline. Normally, you must not go beyond the boundaries of your own rules. Consultation with other projects should be conducted when there is an individual pipeline crossing the boundary.

　?。?）當風管與風機銜接時，應在進出風口處加軟接頭，其軟接頭的斷面尺度應與風機進出風口共同。軟管接頭普通可采用帆布、人造革等資料，濟南螺旋風管軟管長度不宜小于200，松緊度應適合，柔性軟管可緩沖風機的振蕩。

　　(1) When the duct is connected with the fan, a soft joint should be added at the inlet and outlet of the fan. The cross-sectional dimension of the soft joint should be the same as that of the inlet and outlet of the fan. The hose joint can generally use canvas, artificial leather and other information. The length of the hose of Jinan spiral duct should not be less than 200, the tightness should be suitable, and the flexible hose can cushion the vibration of the fan.

　?。?）當風道與除塵設備、濟南螺旋風管加熱設備等銜接前，應待設備安裝終了后，按理論測繪的圖紙中止預制和安裝。

　　(2) Before connecting the air duct with the dust removal equipment and the heating equipment of Jinan spiral air duct, the prefabrication and installation shall be discontinued according to the theoretical mapping drawing after the installation of the equipment.

　　（3）濟南通風管道安裝時，進、出風日宜在風道預制時開出洞口，如需在安裝終了的風道上現開風口，其接口處應嚴密。

　　(3) When installing Jinan ventilation pipeline, the inlet and outlet should be opened when the duct is prefabricated. If the outlet is to be found in the duct after installation, the interface should be tight.

　?。?）當運送含凝結水或含濕量較大的氣體時，其程度管道宜設有坡度，并在低點處接排水管。濟南螺旋風管安裝時風道底部不宜呈現縱向接縫，對底部有接縫處應中止密封處置。

　　(4) When transporting gas with condensate water or high moisture content, the gradient of the pipeline should be set and the drainage pipe should be connected at the low point. When installing the spiral duct in Jinan, the longitudinal seam should not appear at the bottom of the duct, and the sealing treatment should be discontinued at the seam at the bottom.

　?。?）對運送易燃、易爆氣體的鋼板風道，在風道銜接法蘭處應安裝跨接線，并與靜電接地網銜接。

　　(5) For steel plate air ducts transporting flammable and explosive gases, a cross connection shall be installed at the flange of the air duct connection and connected with the electrostatic grounding grid.

　　局部通風系統又分為局部進風和局部排風兩大類，它們都是應用局部氣流，使局部工作地點不受有害物的污染，構成良好的空氣環境。

　　Local ventilation system can be divided into local air intake and local air exhaust. Both of them use local air flow to protect local working places from harmful pollutants and form a good air environment.

　　1）風管穿過建筑物的樓板或隔墻時應設置壁厚不小于1.6mm的防護套管，且在風管與防護套管之間采用對人體無害的不燃柔性資料封堵。

　　1) When the duct passes through the floor or partition wall of a building, a protective sleeve with a wall thickness of not less than 1.6 mm shall be installed, and a non-flammable flexible data blocking between the duct and the protective sleeve sleeve shall be adopted.

　　2）風管裝置時嚴禁直接攀爬倚靠風管。必要時應運用1000mm×2000mm左右的兩塊木板墊腳（增加受力面積），交替行進，保證平安。

　　2) It is strictly forbidden to climb and lean on the duct directly when the duct is installed. When necessary, we should use two wooden board pads (about 1000mm * 2000mm) to increase the stress area, alternately travel, to ensure safety.

　　3）濟南螺旋風管沿墻體或樓板裝置時，距墻面、樓板宜大于100mm。無吊頂明裝風管的裝置位置與標高誤差不應大于10mm。與設備銜接法蘭的螺栓應平均擰緊，其螺母宜在同一側。

　　3) When the spiral air duct is installed along the wall or floor in Jinan, the distance between the spiral air duct and the wall or floor should be greater than 100 mm. The error of installation position and elevation of open air duct without ceiling should not be greater than 10 mm. The bolts of the flange connecting with the equipment should be tightened evenly, and the nuts should be on the same side.
