The installation of hanger in ventilation pipeline is an important link in the construction of ventilation pipeline. The installation of hanger plays an important role in supporting weight, balancing medium reaction, limiting displacement and preventing vibration of pipeline. Therefore, it is necessary for the construction personnel to understand the regulations for installation of hangers, in order to better complete the construction of ventilation pipelines. Next, we will take you to understand the regulations for installation of ceiling in the construction of ventilation pipelines.

　　1、風機、空調機組、風機盤等設備的支、吊架設計要求設置隔振器，其品種、規格應符合設計及產品技術文件要求。

　　1. Vibration isolators are required in the design of brackets and hangers of fan, air conditioning unit and fan disc. The varieties and specifications of vibration isolators should meet the requirements of design and product technical documents.

　　2、風管垂直安裝，間距不應大于4m，單根直管少應有2個固定點。

　　2. The air duct should be installed vertically, and the distance should not be greater than 4m. A single straight duct should have at least two fixed points.

　　3、吊架的螺孔應采用機械加工，吊桿應平直，螺紋完整、光潔。

　　3. The screw holes of the hanger shall be machined. The hanger rods shall be straight, and the threads shall be complete and smooth.

　　4、長度超過20m的水平懸吊風管，在通風管道施工時少設置1個防晃支架。

　　4. Horizontal suspended air duct with length over 20 m shall be provided with at least one anti-sloshing bracket during the construction of the ventilation duct.

　　5、支吊架不宜設置在風口、閥門、檢查門及自控機構處，離風口或插接管的距離不宜小于200mm。

　　5. The support and hanger should not be set at the tuyere, valve, inspection door and automatic control mechanism, and the distance from the tuyere or intubation pipe should not be less than 200 mm.

　　6、平懸吊的主、干風管長度超過20m時應設置防止擺動的固定點，每個系統不應少于1個。

　　6. When the length of main and dry air ducts of horizontal suspension exceeds 20m, fixed points should be set to prevent swing, and each system should not be less than one.

　　7、風管支吊架宜按國標圖集與規范選用強度和剛度相適應的形式和規格，對于直徑或邊長大于2500㎜的超寬、超重特殊風管的支、吊架應按設計規定。

　　7. The support and hanger of air duct should be selected according to the form and specifications of strength and stiffness in accordance with the national standard atlas and specifications, and the support and hanger of extra-wide and extra-heavy special air duct with diameter or edge longer than 2500_should be designed according to the regulations.

　　8、安裝后各副支、吊架的受力應均勻，無明顯變形，風管或空調設備使用的可調隔振支、吊架的拉伸或壓縮量應按設計的要求進行調整。

　　8. After installation, the force of each auxiliary support and hanger should be uniform without obvious deformation. The tension or compression of the adjustable vibration isolation support and hanger used in air duct or air conditioning equipment should be adjusted according to the design requirements.

　　因此，在設計通風管道時，合理布置和正確選擇結構合適的支吊架，能夠改善通風管道的應力分布，確保通風管道的運行，還能夠延長通風管道的使用壽命，以上就是為大家總結的安裝吊架的相關規定，希望能夠對您有所幫助

　　Therefore, in the design of ventilation pipelines, reasonable layout and correct selection of structurally appropriate support and hanger can improve the stress distribution of ventilation pipelines, ensure the safe operation of ventilation pipelines, and also extend the service life of ventilation pipelines. The above is the relevant provisions for the installation of hangers summarized by everyone, hoping to be helpful to you.
