Tin air duct has already become a widely used information in various equipment. Because of its low service life, the need for replacement and maintenance is often stopped. Its detailed equipment replacement methods, iron air duct is here to tell you.

　　1、支吊架制造安裝

　　1. Manufacturing and Installation of Support and Hanger

　　根據標準的請求，對不同規格的鐵皮風管采用不同巨細的支吊架。吊桿的長度要根據鐵皮風管的尺度和安裝高度，以及樓層梁或鋼架的高度來下料加工。吊桿的吊碼用角鋼加工，吊桿的結尾螺紋絲牙要稱心調理鐵皮風管標高的請求，吊桿的頂部與角鋼碼焊接固定，吊桿油防銹漆和面漆各兩遍。吊桿制造好后，就能夠根據鐵皮風管的安頓方位停止安裝，間距契合規劃及標準的請求。

　　According to the requirements of the standard, different supports and hangers with different sizes are adopted for the iron ducts. The length of the suspender should be cut according to the scale and installation height of the iron duct and the height of the floor beam or steel frame. The hanging code of the hanger rod is machined with angle steel. The screw teeth at the end of the hanger rod should adjust the requirement of the elevation of the iron sheet air duct satisfactorily. The top of the hanger rod is welded and fixed with the angle steel code. The anti-rust paint and topcoat of the hanger rod are twice each. After the suspender is manufactured, the installation can be stopped according to the installation orientation of the sheet iron air duct, and the spacing meets the requirements of planning and standards.

　　2、鐵皮風管吊裝

　　2. Hoisting of iron duct

　　根據規劃圖紙和國度標準的請求，停止鐵皮風管安裝。鐵皮風管安裝前，做好組裝件的清潔工作，之后，根據圖紙鐵皮風管各體系的散布，按照制造好的鐵皮風管編號停止擺放、組合，核對鐵皮風管尺度，所在軸線方位契合圖紙后，方可吊裝。

　　Stop the installation of iron ducts according to the requirements of planning drawings and national standards. Before installation of iron duct, do a good job of cleaning the assembly parts. After that, according to the distribution of the system of iron duct in the drawings, stop placing and assembling according to the number of the manufactured iron duct, check the scale of iron duct, and the axis orientation is in line with the drawings, it can be hoisted.

　　吊裝用手動葫蘆，能夠由起重班組配合，留意吊裝時鐵皮風管的均衡升降，以防側滑或傾倒。鐵皮風管用角鋼橫擔固定于支吊架上。鐵皮風管安裝時，主管盡量貼大梁底，支管也盡高安裝。交叉作業時一定要與水施、電施諧和配合好，一同要留意平安。鐵皮風管安裝好后，檢查鐵皮風管的安裝高度能否稱心規劃請求，鐵皮風管的程度、垂直度能否契合標準請求，支架能否傾斜，支架間距能否契合請求。

　　Hand hoist is used for hoisting, which can be coordinated by the hoisting team. Pay attention to the balanced lifting of the iron duct during hoisting, so as to prevent side slip or dumping. The iron sheet air duct is fixed on the support and hanger with angle steel cross-arm. When installing the iron duct, the supervisor shall stick to the bottom of the girder as far as possible, and the branch pipe shall be installed as high as possible. When crossing operation, we must coordinate with water and electricity harmoniously and pay attention to safety together. After the installation of the iron duct, check whether the installation height of the iron duct can meet the planning requirements, whether the degree and verticality of the iron duct can meet the standard requirements, whether the bracket can tilt, and whether the spacing of the bracket can meet the requirements.

　　風管加固措施：矩形風管邊長≥630mm和保溫風管邊長≥800mm,管段長度在1.2m以上必需采用增強筋或其它加固。

　　Wind pipe reinforcement measures: rectangular duct side length (> 630 mm) and insulation duct side length (> 800 mm), pipe section length above 1.2 m must be reinforced or other reinforcement.
