通風(fēng)管道在運(yùn)輸過程應(yīng)有防止損傷風(fēng)管的保護(hù)措施。榫接風(fēng)管的連接在榫口處涂膠粘劑，是為增強(qiáng)接頭處的強(qiáng)度。當(dāng)風(fēng)管采用地面預(yù)組裝后架空安裝時，限制預(yù)組裝的長度是為了遮免風(fēng)管因自重產(chǎn)生的彎曲而破壞構(gòu)件接口。玻璃纖維復(fù)合板風(fēng)管端口為切割面時，在裝配法蘭連接件前應(yīng)將管端切口面用膠帶或膠液進(jìn)行封堵，才能防止玻璃纖維外露和飛散。

The ventilation duct shall be protected from damage during transportation. For the connection of tenon air duct, adhesive shall be applied at the tenon to enhance the strength of the joint. When the air duct is installed overhead after ground pre assembly, the length of pre assembly is limited to prevent the bending of the air duct due to its own weight from damaging the component interface. When the end of the fiberglass composite board air duct is the cutting surface, the cut surface of the duct end shall be sealed with tape or glue before assembling the flange connector to prevent the fiberglass from being exposed and flying away.

工作通道寬度應(yīng)滿足施工要求，在通道內(nèi)應(yīng)有覆蓋物，鋪設(shè)腳手架。作業(yè)過程中，應(yīng)隨時派專人檢查工作通道和腳手架。如發(fā)現(xiàn)變形和位移，應(yīng)及時采取措施，并確認(rèn)。

The width of the working passage shall meet the construction safety requirements, and the passage shall be covered with scaffolding. During the operation, special personnel shall be assigned to check the working channel and scaffold at any time. If deformation and displacement are found, safety measures shall be taken in time and safety shall be confirmed.

直線的實(shí)長或平面的實(shí)形，確定展開方法和畫展開圖這幾個部分。在進(jìn)行展開下料前，要熟悉施工圖紙，這是一項準(zhǔn)備工作，主要是對將要展開的關(guān)鍵和部件有所了解，濟(jì)南通風(fēng)管道管道在圖紙上的尺寸大小、制作材料等。而對于比較復(fù)雜的管件，則需要對施工圖紙進(jìn)行反復(fù)閱讀和分析，針對有關(guān)問題要及時提出和解決。由于通風(fēng)管件及其部件在圖紙上都是幾何圖形，而對形體進(jìn)行分析的主要目的就是將復(fù)雜的幾何圖形簡單化。通過分析，以便找到恰當(dāng)?shù)恼归_方法。

The real length of a straight line or the real shape of a plane, the determination of the expansion method and the drawing of the expansion diagram. Before launching blanking, first get familiar with the construction drawings, which is a preparatory work, mainly to understand the key and components to be launched, the size and fabrication materials of Jinan ventilation pipeline on the drawings. For more complex pipe fittings, the construction drawings need to be read and analyzed repeatedly, and relevant problems should be put forward and solved in time. As the ventilation pipe fittings and their components are geometric figures on the drawings, the main purpose of shape analysis is to simplify the complex geometric figures. Through analysis, in order to find the appropriate expansion method.

當(dāng)測量斷面設(shè)在彎頭、三通等異形部件后面時，距這些部件的距離應(yīng)大于4～5倍管道直徑。濟(jì)南通風(fēng)管道測試現(xiàn)場難于滿足要求時，為減少誤差可適當(dāng)增加測點(diǎn)。但是，測量斷面位置距異形部件的Z小距離少是管道直徑的1.5倍。通風(fēng)管道風(fēng)管主要應(yīng)用在工業(yè)及建筑工程中， 應(yīng)用領(lǐng)域有：適用于工業(yè)、各種建筑的空調(diào)通風(fēng)工程安裝，廣泛應(yīng)用在食品加工、機(jī)械制造、藥業(yè)制品、電子工業(yè)、購物、棉紡織、體育娛樂場所、酒店、賓館、、寫字樓、、小型別墅、航空航天制造等領(lǐng)域.

When the measuring section is set behind the elbow, tee and other special-shaped parts, the distance from these parts shall be more than 4-5 times the pipe diameter. When it is difficult to meet the requirements of Jinan ventilation pipeline testing site, the measuring points can be appropriately increased to reduce the error. However, the Z small distance between the measuring section location and the profiled part is at least 1.5 times of the pipe diameter. The air duct of ventilation duct is mainly used in industrial and architectural projects. The application fields are: applicable to the installation of air conditioning and ventilation projects in industrial and various buildings, widely used in food processing, machinery manufacturing, pharmaceutical products, electronic industry, shopping centers, cotton textiles, sports and entertainment venues, hotels, hotels, supermarkets, office buildings, government agencies, small villas, aerospace manufacturing and other fields
