通風管道吊架安裝是大世界通風管道施工中一個很重要的環(huán)節(jié)，對管道起著支承重量、平衡介質反力、限制位移和防止震動等作用。下面濟南通風管道廠家?guī)Т蠹伊私庖幌峦L管道施工中吊頂安裝有哪些規(guī)定：

The installation of ventilation duct hanger is a very important link in the construction of ventilation duct in the world. It plays the role of supporting weight, balancing medium reaction, limiting displacement and preventing vibration. Below, Jinan ventilation duct manufacturer will take you to know what are the regulations for ceiling installation in ventilation duct construction:

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(guī)格應符合設計及產品技術文件要求。

1. The supports and hangers of fans, air conditioning units, fan panels and other equipment shall be designed with vibration isolators, and their varieties and specifications shall meet the requirements of design and product technical documents.

2、風管支丶吊架宜按國標圖集與規(guī)范選用強度和剛度相適應的形式和規(guī)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(guī)定。

2. The support and hanger of air duct should adopt the form and specification suitable for the strength and rigidity according to the national standard atlas and specifications. The support and hanger of super wide and overweight special air duct with diameter or side length greater than 2500 mm should be in accordance with the design regulations.

3、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。

3. The air duct shall be installed vertically, the spacing shall not be more than 4m, and a single straight pipe shall have at least two fixed points.

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

4. When the length of horizontally suspended main and main air ducts exceeds 20m, fixed points to prevent swing shall be set, and each system shall not be less than 1.

5、吊架的螺孔應采用機械加工，吊桿應平直，螺紋完整、光潔。

5. The screw hole of the hanger shall be machined, the hanger rod shall be straight, and the thread shall be complete and smooth.

6、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。

6. The support and hanger should not be set at the air outlet, valve, inspection door and automatic control mechanism, and the distance from the air outlet or plug-in pipe should not be less than 200 mm.

7、長度超過20m的水平懸吊風管，應設置少1個防晃支架。

7. At least one anti sway support shall be set for horizontal suspended duct with length over 20m.

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 stress of each auxiliary support and hanger shall be uniform without obvious deformation. The tension or compression of adjustable vibration isolation support and hanger used for air duct or air conditioning equipment shall be adjusted according to the design requirements.

在通風管道設，合理布置和正確選擇結構合適的支吊架，能改善通風管道的應力分布，確保通風管道安 全運行并延長通風管道的使用壽命。

In the design of ventilation duct, reasonable layout and correct selection of supports and hangers with appropriate structure can improve the stress distribution of ventilation duct, ensure the safe operation of ventilation duct and prolong the service life of ventilation duct.
