通风管道吊架安装是通风管道施工中一个很重要的环节,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。下面济南通风管道加工厂家带大家了解一下通风管道施工中吊顶安装有哪些规定:
The installation of ventilation pipe hanger is a very important link in the construction of ventilation pipe. It plays the role of supporting weight, balancing medium reaction, limiting displacement and preventing vibration. Next, Jinan ventilation duct processing factory will show you the regulations on ceiling installation during ventilation duct construction:
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. 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 the design and product technical documents.
2、风管支丶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。
2. The support and hanger of air duct shall be in the form and specification corresponding to the strength and stiffness according to the national standard atlas and specifications. The support and hanger of ultra wide and overweight special air duct with diameter or side length greater than 2500 mm shall be in accordance with the design regulations.
3、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。
3. The air duct shall be installed vertically, the spacing shall not be greater than 4m, and a single straight pipe shall have at least 2 fixing points.
4、当水平悬吊的主、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。
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、吊架的螺孔应采用机械加工,吊杆应平直,螺纹完整、光洁。
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。
6. The supports and hangers shall 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 shall not be less than 200mm.
7、长度超过20m的水平悬吊风管,应设置少1个防晃支架。
7. Horizontal suspended air ducts with a length of more than 20m shall be provided with at least one anti sway support.
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 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.
在通风管道设,合理布置和正确选择结构合适的支吊架,能改善通风管道的应力分布,确保通风管道运行并延长通风管道的使用寿命。
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.
