按截面形狀，風管可分為圓形風管，矩形風管，扁圓風管等多種，其中圓形風管阻力較小的高度尺寸較大，制作復雜。所以應用以矩形風管為主。下來一起來了解一下風管制作施工中的一些要求：
According to the cross-section shape, the duct can be divided into round duct, rectangular duct, flat circular duct and so on. The circular duct has the largest height dimension with the smallest resistance and is complicated to manufacture. So the rectangular duct is the main application. Come down to understand some requirements in the construction of the duct.
（1）風管制作施工應按設計規定，風管（包括三通、彎頭的功能配件）采用相應的合格材料，厚度按圖紙施工。
(1) The construction of air duct shall be carried out according to the design stipulations, and the air duct (including the functional fittings of tees and elbows) shall be constructed according to the corresponding qualified materials and the thickness of the air duct shall be constructed according to the drawings.
（2）圓形彎管半徑應大于等于2倍彎管直徑。
(2) the radius of the Circular Bend should be greater than or equal to 2 times the diameter of the elbow.
（3）矩形風管的彎管，可采用內弧或內斜線彎管。當邊長大于或等于500mm時，應設置導流行。
(3) the elbow of the rectangular duct can be internally curved or inlined. When the side length is greater than or equal to 500mm, guide popularity should be set.
（5）風管與配件的表面平整，圓弧應均勻。咬口縫應嚴密、寬度應一致，并不得有十字交叉的拼接縫。
(5) the surface of the wind pipe and fittings is smooth and the arc should be uniform. The seam should be tight and the width should be the same, and no cross stitching should be allowed.
（6）不同系統風管的連接方式要符合相應的要求根據，送排風采用共板法蘭連接方式，防排煙系統采用角鋼法蘭連接。
(6) The connection mode of the air ducts of different systems should meet the corresponding requirements. The air supply and exhaust systems are connected by common plate flange, and the smoke control and exhaust systems are connected by angle steel flange.
（7）共板法蘭連接風管四角處的角件與法蘭四角接口的固定應緊貼，端面應平整，相連處不應有大于2mm的連續穿透縫。
(7) The corners of the common plate flanged connection air duct should be fixed close to the corner of the flange, the end face should be smooth, and there should not be a continuous penetrating seam greater than 2 mm at the joint.
（8）薄鋼板法蘭的彈性插條、彈簧夾的緊固螺栓(鉚釘)應分布均勻，間距不應大于150mm，較外端的連接件距風管邊緣不應大于100mm。
(8) The elastic strip of the thin plate flange and the fastening bolt (rivet) of the spring clamp shall be evenly distributed, the spacing shall not be greater than 150 mm, and the outermost connector shall not be greater than 100 mm from the edge of the air duct.
（9）組合型薄鋼板法蘭與風管管壁的組合，應調整法蘭口的平面度后，再將法蘭條與風管鉚接（或本體鉚接）。
(9) For the combination of the combined thin steel plate flange and the air duct wall, the flange should be riveted (or riveted) with the air duct after adjusting the flatness of the flange opening.
（10）風管的密封，應以板材連接的密封為主，通風管道可用普通膠條，防排煙系統要用不然密封材料。
(10) The sealing of the air duct should be based on the sealing of the plate connection, the ventilation duct can be used with ordinary adhesive tape, and the smoke control and exhaust system should use the unnatural sealing material.
（11）當矩形風管邊長大于或等于630mm和保溫風管邊長大于或等于800mm，且其管段長度大于1200mm時，均采取加固措施，采用直徑為8mm通絲螺桿加固。對邊長小于或等于800mm的風管，宜采用楞筋、楞線的方法加固。
(11) When the rectangular air duct edge is larger than or equal to 630 mm and the insulation air duct edge is larger than or equal to 800 mm, and the length of the pipe section is longer than 1200 mm, reinforcement measures are taken, using 8 mm diameter through-screw reinforcement. For the wind pipe with a length of less than or equal to 800mm, it is advisable to reinforce it with corrugated steel bars and corrugated wires.
（12）法蘭端面粘貼密封膠條并緊固法蘭四角螺絲后，方可安裝插條或彈簧夾、頂絲卡。彈簧夾、頂絲卡不應松動。
(12) Installation of inserts or spring clips or plug-in clips can be accomplished only after the end face of the flange is pasted with sealant strips and the four-corner screws of the flange are fastened. Spring clips and top wire cards should not be loosened.
