三分PK拾按截面形状,风管可分为圆形风管,矩形风管,扁圆风管等多种,其中圆形风管阻力最小的高度尺寸最大,制作复杂。所以应用以矩形风管为主。下来一起来了解一下风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)风管制作施工应按设计规定,风管(包括三通、弯头的功能配件)采用相应的合格材料,厚度按图纸施工。

(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)圆形弯管半径应大于等于2倍弯管直径。

三分PK拾(2) the radius of the Circular Bend should be greater than or equal to 2 times the diameter of the elbow.

(3)矩形风管的弯管,可采用内弧或内斜线弯管。当边长大于或等于500mm时,应设置导流行。

(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。

三分PK拾(5)风管与配件的表面平整,圆弧应均匀。咬口缝应严密、宽度应一致,并不得有十字交叉的拼接缝。

(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)不同系统风管的连接方式要符合相应的要求根据,送排风采用共板法兰连接方式,防排烟系统采用角钢法兰连接。

(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)共板法兰连接风管四角处的角件与法兰四角接口的固定应紧贴,端面应平整,相连处不应有大于2mm的连续穿透缝。

(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。

三分PK拾(8)薄钢板法兰的弹性插条、弹簧夹的紧固螺栓(铆钉)应分布均匀,间距不应大于150mm,最外端的连接件距风管边缘不应大于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)组合型薄钢板法兰与风管管壁的组合,应调整法兰口的平面度后,再将法兰条与风管铆接(或本体铆接)。

(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)风管的密封,应以板材连接的密封为主,通风管道可用普通胶条,防排烟系统要用不然密封材料。

三分PK拾(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.

三分PK拾(11)当矩形风管边长大于或等于630mm和保温风管边长大于或等于800mm,且其管段长度大于1200mm时,均采取加固措施,采用直径为8mm通丝螺杆加固。对边长小于或等于800mm的风管,宜采用楞筋、楞线的方法加固。

(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)法兰端面粘贴密封胶条并紧固法兰四角螺丝后,方可安装插条或弹簧夹、顶丝卡。弹簧夹、顶丝卡不应松动。

(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.
