专注通风管道加工·排烟罩

　　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、支吊架制造安装

　　1. Manufacturing and Installation of Support and Hanger

　　根据标准的请求，对不同规格的铁皮风管采用不同巨细的支吊架。吊杆的长度要根据铁皮风管的尺度和安装高度，以及楼层梁或钢架的高度来下料加工。吊杆的吊码用角钢加工，吊杆的结尾螺纹丝牙要称心调理铁皮风管标高的请求，吊杆的顶部与角钢码焊接固定，吊杆油防锈漆和面漆各两遍。吊杆制造好后，就能够根据铁皮风管的安顿方位停止安装，间距契合规划及标准的请求。

　　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、铁皮风管吊装

　　2. Hoisting of iron duct

　　根据规划图纸和国度标准的请求，停止铁皮风管安装。铁皮风管安装前，做好组装件的清洁工作，之后，根据图纸铁皮风管各体系的散布，按照制造好的铁皮风管编号停止摆放、组合，核对铁皮风管尺度，所在轴线方位契合图纸后，方可吊装。

　　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.

　　吊装用手动葫芦，能够由起重班组配合，留意吊装时铁皮风管的均衡升降，以防侧滑或倾倒。铁皮风管用角钢横担固定于支吊架上。铁皮风管安装时，主管尽量贴大梁底，支管也尽高安装。交叉作业时一定要与水施、电施谐和配合好，一同要留意平安。铁皮风管安装好后，检查铁皮风管的安装高度能否称心规划请求，铁皮风管的程度、垂直度能否契合标准请求，支架能否倾斜，支架间距能否契合请求。

　　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.

　　风管加固措施：矩形风管边长≥630mm和保温风管边长≥800mm,管段长度在1.2m以上必需采用增强筋或其它加固。

　　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.
