Smoke exhaust hood is very important in urban construction, especially its installation quality is also harmful to gas exchange and endangers people's work efficiency. Then, the installation quality of smoke hood will be affected by various factors. What is the content?

做好項目施工前的準備工作。做好充分的準備是保證排煙罩安裝質量的前提。提前準備制造凈化處理用排煙罩時，無論是加工廠集中制造方式還是現場制造方式，都需要保證場所清潔密閉，有符合條件的照明和照明標準。此外，還需要對準備好的管道進行愛護，以盡量減少對環境的污染。

Make preparations before project construction. Adequate preparation is the premise to ensure the installation quality of smoke hood. When preparing the manufacturing of smoke hood for purification treatment in advance, whether it is centralized manufacturing in the processing plant or on-site manufacturing, it is necessary to ensure that the place is clean and closed, and there are qualified lighting and lighting standards. In addition, it is also necessary to take good care of the prepared pipelines to minimize environmental pollution.

材料的選擇。材料的選擇對排煙罩的施工質量也有很大的危害。一般來說，為了更好地保證排煙罩的凈重，需要選擇板厚較小的排煙罩，但除此之外，還要綜合考慮排煙罩的規格和工作壓力等級。從設計方案來看，特別注意的是，一個系統軟件可以額外存儲多種類型的排煙罩板厚度，以匹配不同的負壓等級。

Selection of materials. The selection of materials also does great harm to the construction quality of smoke exhaust hood. Generally speaking, in order to better ensure the net weight of the smoke exhaust hood, the smoke exhaust hood with smaller plate thickness needs to be selected, but in addition, the specification and working pressure level of the smoke exhaust hood should be comprehensively considered. From the point of view of the design scheme, it is particularly noted that a system software can additionally store various types of smoke exhaust hood plate thickness to match different negative pressure levels.

排煙罩的水平連接。排煙罩的水平連接應注意一定的問題。這種接口方式可以說是保持風道長度的一種方式。它還具有提高抗彎剛度和保持排煙罩水平規格的作用。一般橫向連接的方法是角鐵彎套法蘭。這種接口類型取決于壁厚，還取決于板墻結構的連接類型和加固方法。

Horizontal connection of smoke exhaust hood. Some problems should be paid attention to in the horizontal connection of smoke exhaust hood. This interface mode can be said to be a way to maintain the length of the air duct. It also has the function of improving the bending stiffness and maintaining the horizontal specification of the smoke exhaust hood. Generally, the method of transverse connection is angle iron bent sleeve flange. This type of interface depends on the wall thickness, as well as the connection type and reinforcement method of the plate wall structure.

排煙罩垂直接縫緊密連接。排煙罩的垂直接縫緊密連接方式可根據具體情況選擇。在中壓排煙罩和底壓排煙罩中，經常使用紐扣式接頭。對于矩形框架排煙罩，接頭壓槽的應用沒有工作壓力等級。因此，按鈕式接頭的應用可以節省逆向工藝流程。在這個階段，大部分風道的垂直接縫通過紐扣式咬合緊密連接。對于立縫和密封立縫，可用螺栓、自攻螺釘、焊接、壓花等方式進行緊固。

The vertical joints of the smoke exhaust hood are closely connected. The vertical joint tight connection mode of smoke exhaust hood can be selected according to specific conditions. Button joints are often used in medium pressure smoke exhaust hood and bottom pressure smoke exhaust hood. For rectangular frame smoke hood, the application of joint pressure groove has no working pressure grade. Therefore, the application of button joint can save the reverse process flow. At this stage, the vertical joints of most air ducts are closely connected through button bite. For vertical joints and sealing vertical joints, bolts, self tapping screws, welding, embossing and other methods can be used for fastening.

濟南排煙罩的存放。預制排煙罩必須妥善保管，防止二次污染。支管可用塑料薄膜等橡膠密封條密封，然后排煙罩進行分類堆放。使用排煙罩前，注意進行徹底的清潔工作，確保板面耐腐蝕，干燥后不要揚塵。

Storage of smoke hood in Jinan. The prefabricated smoke exhaust hood must be kept properly to prevent secondary pollution. The branch pipe can be sealed with rubber sealing strips such as plastic film, and then the smoke exhaust hood is stacked by category. Before using the smoke exhaust hood, pay attention to thorough cleaning to ensure the corrosion resistance of the board surface, and do not raise dust after drying.
