Installation method of galvanized iron sheet air duct
Galvanized iron sheet air duct has long been a widely used material, which is found in various facilities. Due to its low service life, it needs to be replaced and maintained frequently. The specific installation and replacement methods of iron sheet air duct are described here.
1. Support and hanger manufacturing device
According to the requirements of the specification, supports and hangers of different sizes are adopted for iron sheet air ducts of different specifications. The length of the suspender shall be cut and processed according to the scale and device height of the iron sheet air duct and the height of the floor beam or steel frame. The hanging code of the suspender shall be processed with angle steel, the thread thread at the end of the suspender shall meet the requirements of adjusting the elevation of iron sheet air duct, the * part of the suspender shall be welded and fixed with the angle steel code, and the suspender shall be painted with antirust paint and finish paint twice. After the suspender is manufactured, the device can be installed according to the placement orientation of iron sheet air duct, and the spacing meets the requirements of planning and specifications.

2. Hoisting of iron sheet air duct
Install iron sheet air duct according to the requirements of planning drawings and home specifications. Before installing the galvanized sheet iron air duct, clean the assembly parts. Then, place and combine the sheet iron air duct according to the distribution of each system of the sheet iron air duct in the drawing and the number of the manufactured sheet iron air duct. Check the scale of the sheet iron air duct and the axis orientation before hoisting.
The manual hoist for hoisting can be coordinated by the hoisting team. Pay attention to the balanced lifting of the iron sheet air duct during hoisting to prevent sideslip or dumping. Galvanized iron sheet air duct is fixed on supports and hangers with angle steel cross arm. When installing galvanized iron sheet air duct, the main pipe shall be close to the bottom of the girder as much as possible, and the branch pipe shall be as high as possible. During interspersed operation, it must be well coordinated with water and electricity construction, and pay attention to it together. After the installation of iron sheet air duct, check whether the device height of iron sheet air duct meets the planning requirements, whether the level and perpendicularity of iron sheet air duct meet the specification requirements, whether the support is skewed, and whether the support spacing meets the requirements.
