Among different types of ventilation ducts, ventilation ducts have become a widely used material and are commonly used in various construction facilities. However, ventilation ducts also have related service life. After a period of time, they need to be replaced in time. How can the pipeline be installed in place? Our manufacturer has compiled the following points for you based on years of installation experience.
1. Support and hanger manufacturing device
According to the requirements of the specification, different sizes of support pipes and hangers are used for the ventilation pipes of different specifications, and the length of the hanger bar should be processed according to the size of the iron duct and the height of the device, and the height of the floor beam or steel frame. The hanger code of the hanger is processed with angle steel. The end thread of the hanger must satisfy the requirements of adjusting the elevation of the ventilation duct. The top of the hanger is welded and fixed with the angle steel code. After the boom is manufactured, the device can be installed according to the placement of the iron duct, and the spacing meets the requirements of the planning and specifications.
2. Hoisting of ventilation ducts
According to the requirements of the planning drawings and national regulations, clean the assembly before the ventilation duct installation and the iron duct installation. After that, according to the distribution of the various systems of the iron duct, according to the drawings, the arrangement is made according to the number of the manufactured iron duct After putting and combining, check the scale of the iron duct, and the axis position should match the drawing before lifting.
The manual hoist for hoisting can be coordinated by the lifting team, pay attention to the balanced lifting during hoisting to prevent side slipping or toppling. The iron duct is fixed on the support hanger with an angle steel crossarm. For the iron duct installation, the supervisor should stick to the bottom of the beam as much as possible, and the branch pipe should also be installed as high as possible. When interspersing, coordinate with the water and electricity supply, and pay attention to safety together. After the iron duct installation is complete, check the iron duct installation Whether the height is satisfactory to the planning requirements, whether the level and verticality of the iron duct meet the specification requirements, whether the brackets are skewed, and whether the bracket spacing meets the requirements.
