如何安装通风管道中风管与支吊架。
How to install ventilation ducts, ducts, and supports and hangers.
1.风管
1. Air duct
(1)支气管的安裝须在工程建筑围封物的工程施工後开展，而该地址早已清除结束。
(1) The installation of the bronchus must be carried out after the construction of the engineering building enclosure, and the address has already been cleared.
(2)在设定管路以前，要科学研究管路的位置、海拔高度、方位等，为了实现设计方案规定，保证孔的位置务必恰当，孔的尺寸务必在管路外的规格的100mm左右。
(2) Before setting the pipeline, it is necessary to scientifically study the position, altitude, orientation, etc. of the pipeline. In order to achieve the design scheme requirements, it is necessary to ensure that the position of the holes is appropriate, and the size of the holes must be around 100mm outside the pipeline.
(3)在解决支气管时，须避免撞击或跌落，以防毁坏支气管。安裝前要消除尘土和脏物。假如安裝全过程中出現中止，应关掉风管张口，以避免尘土和脏东西进到风管。
(3) When solving bronchi, it is necessary to avoid hitting or falling to prevent damage to the bronchi. Dust and dirt should be removed before installation. If there is a suspension during the entire installation process, the air duct opening should be closed to prevent dust and dirt from entering the air duct.
(4)支气管不可在墙面或木地板上安裝页面，亦不得安裝喉咙、电线及电缆线。
(4) Bronchial tubes should not be installed on walls or wooden floors, nor should throats, wires, and cables be installed.
(5)输气管可燃气体时，或是处在这类自然环境下时，假如需要采用接地装置对策来安全防护温度超出80℃的气体，请采用安全防护对策。
(5) If it is necessary to use grounding devices to safely protect gases with temperatures exceeding 80 ℃ when transporting combustible gases in the gas pipeline or in such natural environments, please use safety protection measures.
(6)务必开展密封性解决，以防管路底端无缝。
(6) It is essential to carry out sealing solutions to prevent seamless bottom of the pipeline.
(7)管路穿过木地板和墙面时，应应用埋进管和安全防护防水套管，中间应密封性柔性原材料。
(7) When pipelines pass through wooden floors and walls, buried pipes and safety protection waterproof sleeves should be used, and the middle should be sealed with flexible raw materials.
(8)当风喉与机器设备联接时，须在其布线处设定一个柔性短管，其长短须为150-300mm或要求的长短。
(8) When the air duct is connected to the machine equipment, a flexible short pipe must be installed at its wiring point, with a length of 150-300mm or the required length.
(9)测量冷轧焊接风阀的孔的位置，须在没有产生涡流的区域内选定，并须方便测量和观察。
(9) The position of the hole for measuring the cold rolled welding air valve must be selected in an area without generating eddy currents, and it must be convenient for measurement and observation.
2.支吊架
2. Supports and hangers
(1)支吊架的所有配件，其所用材料的使用，应符合设计要求以及参数要求。
(1) The use of materials for all accessories of supports and hangers should meet the design requirements and parameter requirements.
(2)管路的较大容许安裝间距，吊架的规格型号应符合规定。
(2) The allowable installation spacing of pipelines and the specifications and models of hangers should comply with regulations.
(3)支吊架埋件安裝恰当，坚固靠谱。埋件应清理，露出一部分应防腐蚀。
(3) The installation of embedded parts for supports and hangers is appropriate and reliable. The embedded parts should be cleaned, and the exposed part should be corrosion-resistant.
(4)切勿将支撑点支架设定在机器设备的实际操作部。 固定不动支撑点支架时，应用胀形钢筋锚固地脚螺栓开展固定不动，应用胀形钢筋锚固地脚螺栓务纤维 驱鸟设备 保定通风管道 塑料土工格栅 检查井模具 流水槽模具 锻造厂家 华尔街铜牛必符合要求的规定。
(4) Do not set the support point bracket on the actual operating part of the machine equipment. When fixing the fixed support point bracket, the expansion steel bars should be used to anchor the anchor bolts for fixation. The expansion steel bars should be used to anchor the anchor bolts, which must comply with the required regulations.
