通风管道的吊架安装是通风管道施工中一个重要环节，吊架安装对管道起着支承重量、平衡介质反力、限制位移和防止震动等作用。因此就需要施工人员了解安装吊架的规定，才能更好的完成通风管道施工工程，接下来带大家了解一下通风管道施工中吊顶安装的规定。
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、风机、空调机组、风机盘等设备的支、吊架设计要求设置隔振器，其品种、规格应符合设计及产品技术文件要求。
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、风管垂直安装，间距不应大于4m，单根直管少应有2个固定点。
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、吊架的螺孔应采用机械加工，吊杆应平直，螺纹完整、光洁。
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、长度超过20m的水平悬吊风管，在通风管道施工时少设置1个防晃支架。
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、支吊架不宜设置在风口、阀门、检查门及自控机构处，离风口或插接管的距离不宜小于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、平悬吊的主、干风管长度超过20m时应设置防止摆动的固定点，每个系统不应少于1个。
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、风管支吊架宜按国标图集与规范选用强度和刚度相适应的形式和规格，对于直径或边长大于2500㎜的超宽、超重特殊风管的支、吊架应按设计规定。
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、安装后各副支、吊架的受力应均匀，无明显变形，风管或空调设备使用的可调隔振支、吊架的拉伸或压缩量应按设计的要求进行调整。
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，在设计通风管道时，合理布置和正确选择结构合适的支吊架，能够改善通风管道的应力分布，确保通风管道的运行，还能够延长通风管道的使用寿命，以上就是为大家总结的安装吊架的相关规定，希望能够对您有所帮助
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.
