通風管道封閉連接的成功是整個通風管道系統安裝成功的關鍵。如果通風管道的封閉連接不合格，在使用過程中就會發生管道系統的泄漏。因此，在進行通風管道的封閉連接時，我們得要注意以下注意事項。

The success of closed connection of ventilation duct is the key to the successful installation of the whole ventilation duct system. If the closed connection of the ventilation pipe is unqualified, the leakage of the pipe system will occur in the process of use. Therefore, we should pay attention to the following precautions when carrying out the closed connection of the ventilation duct.

1.矩形風管的直管段，無論是由同一塊板連接還是由幾塊板拼接而成，都應具有平整的表面和平直的轉角線。組合前，應板材切割面上的切割粉、灰塵和雜物。

1. The straight pipe section of rectangular air duct, whether connected by the same plate or spliced by several plates, should have a flat surface and a straight corner line. Before combination, the cutting powder, dust and sundries on the cutting surface of the plate shall be removed.

2.管段組合后，45度角切邊的外接頭應貼在鋁箔膠帶封板的殼面上，每邊寬度不小于20mm。用直角尺和鋼卷尺檢查調整垂直度和對角線偏差，符合規范要求。

2. After the combination of pipe sections, the outer joint with 45 degree angle trimming shall be pasted on the shell surface of the aluminum foil tape sealing plate, and the width of each side shall not be less than 20mm. Check and adjust the perpendicularity and diagonal deviation with a square and steel tape to meet the specification requirements.

3.風管的弧面或折線面下料折疊完成后，應先用平板預組裝，然后涂上膠粘劑，以保證管件的幾何形狀、尺寸和外觀。

3. After blanking and folding of the arc surface or broken line surface of the air duct, it should be pre assembled with a flat plate, and then coated with adhesive to ensure the geometry, size and appearance of the pipe fittings.

4.在連接和組合后，管段應垂直放置以在移動前定型。

4. After connection and combination, the pipe section should be placed vertically to shape before moving.

5.鋁箔復合保溫風管所用的膠粘劑得要是板材制造商認可的專用膠粘劑。如果單獨購買膠，得要做連接效果對比試驗，經監理和板材廠家檢查認可后方可使用。

5. The adhesive used for aluminum foil composite insulation air duct shall be the special adhesive approved by the plate manufacturer. If the brand glue is purchased separately, the connection effect comparison test must be done, and it can only be used after being checked and approved by the supervisor and the plate manufacturer.

6.濟南通風管道加工人員認為粘合前需要進行預裝配，然后在檢查所有接頭是否正確配合后涂上粘合膠。粘合時間的控制與季節、溫度和粘合劑性能有關。批量加工前應進行樣品測試，以確定很好粘合時間。

6. Jinan ventilation pipe processing personnel believe that pre assembly is required before bonding, and then apply adhesive after checking whether all joints fit correctly. The control of bonding time is related to season, temperature and adhesive performance. Sample testing should be carried out before batch processing to determine a good bonding time.

夏熱冬冷地區或者夏熱冬暖地區的建筑熱工設計應當符合現行標準的規定；當采用通風屋面隔熱時，通風層長度不宜超過10m，空氣層高度宜為20cm左右。

The thermal design of buildings in hot summer and cold winter areas or hot summer and warm winter areas shall comply with the provisions of the current national standards; When ventilation roof insulation is adopted, the length of ventilation layer should not exceed 10m, and the height of air layer should be about 20cm.
