通風(fēng)管道封閉連接的成功是整個(gè)通風(fēng)管道系統(tǒng)安裝成功的關(guān)鍵。如果通風(fēng)管道的封閉連接不合格，在使用過(guò)程中就會(huì)發(fā)生管道系統(tǒng)的泄漏。因此，在進(jìn)行通風(fēng)管道的封閉連接時(shí)，我們得要注意以下注意事項(xiàng)。

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(fēng)管的直管段，無(wú)論是由同一塊板連接還是由幾塊板拼接而成，都應(yīng)具有平整的表面和平直的轉(zhuǎn)角線。組合前，應(yīng)清除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(yīng)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(diào)整垂直度和對(duì)角線偏差，符合規(guī)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(fēng)管的弧面或折線面下料折疊完成后，應(yīng)先用平板預(yù)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(yīng)垂直放置以在移動(dòng)前定型。

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

5.鋁箔復(fù)合保溫風(fēng)管所用的膠粘劑得要是板材制造商認(rèn)可的專用膠粘劑。如果單獨(dú)購(gòu)買膠，得要做連接效果對(duì)比試驗(yàn)，經(jīng)監(jiān)理和板材廠家檢查認(rèn)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(jì)南通風(fēng)管道加工人員認(rèn)為粘合前需要進(jìn)行預(yù)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(shí)間的控制與季節(jié)、溫度和粘合劑性能有關(guān)。批量加工前應(yīng)進(jìn)行樣品測(cè)試，以確定很好粘合時(shí)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(qū)或者夏熱冬暖地區(qū)的建筑熱工設(shè)計(jì)應(yīng)當(dāng)符合國(guó)家現(xiàn)行標(biāo)準(zhǔn)的規(guī)定；當(dāng)采用通風(fēng)屋面隔熱時(shí)，通風(fēng)層長(zhǎng)度不宜超過(guò)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.
