在通风管道中，除了风管，还有一些支吊架等配件，因而它的装置就分为两有些，一有些是风管，包含螺旋风管、矩形风管等，还有一有些即是支吊架，下面就来详细介绍这两有些内容。
In the ventilation duct, in addition to the air duct, there are some supports and hangers and other accessories. Therefore, its devices are divided into two parts: one is air duct, including spiral air duct and rectangular air duct, and the other is support and hanger. The following will introduce these two parts in detail.
1.风管
1. Air duct
(1)应在建筑物围护结构施工完结，以及场合整理完结后进行风管的装置。
(1) The installation of air duct should be carried out after the completion of building envelope construction and finishing of occasions.
(2)装置风管前，应对风管的方位，标高以及走向等进行复核，要契合规划请求，预留孔的方位应准确，孔洞的巨细应大于风管外边尺度的100mm及以上。
(2) Before installing the air duct, the orientation, elevation and direction of the air duct should be rechecked to meet the planning requirements. The orientation of the reserved hole should be accurate, and the size of the hole should be greater than 100 mm or more of the outer dimension of the air duct.
(3)风管转移时应避免发作碰撞或摔打，避免损害风管。装置前应整理掉粉尘以及杂物，装置过程中如有中止，应关闭风管口，以防有灰尘及异物进入风管。
(3) When the air duct is transferred, the collision or falling should be avoided to avoid damaging the air duct. Before installation, dust and sundries should be cleaned up. If there is a stop in the process of installation, the air duct orifice should be closed to prevent dust and foreign matters from entering the air duct.
(4)风管的接口不能装置在墙内或楼板内，风管内不能敷设管道、电线以及电缆。
(4) The interface of the air duct shall not be installed in the wall or floor, and pipes, wires and cables shall not be laid in the air duct.
(5)风管如果是运送易燃易爆的气体，或者是处于这种环境中，那么应有必要的接地办法进行防护;如果是运送温度高于80℃的空气，则应采纳必要的防护办法。
(5) If the air duct is transporting inflammable and explosive gas or is in such environment, necessary grounding method shall be adopted for protection; if it is to transport air with temperature higher than 80 ℃, necessary protection measures shall be adopted.
(6)风管的底部不宜有拼接缝，如有应做好密封处理。
(6) The bottom of the air duct should not have joint, if any, it should be sealed.
(7)风管如要穿过楼板或墙体，则应运用预埋管或防护套管，它们之间还要有柔性资料进行封堵。
(7) If the air duct is to pass through the floor or wall, the embedded pipe or protective sleeve should be used, and flexible data should be used for plugging between them.
(8)风管与设备相连接时，其连接处应有柔性短管，长度为150—300mm，或者是规则的长度请求。
(8) When the air duct is connected with the equipment, there should be a flexible short pipe with a length of 150-300 mm, or a regular length request.
(9)风管测定孔的方位应选在不发生涡流的区域，且要便于丈量和调查。
(9) The orientation of air duct measuring hole should be selected in the area without eddy current, and it should be convenient for measurement and investigation.
2.支吊架
2. Supports and hangers
(1)支吊架的一切配件，其所用资料的运用，应契合规划请求以及参数请求。
(1) All accessories of supports and hangers shall be used in accordance with planning requirements and parameter requirements.
(2)在风管的答应装置间隔下，吊架的更小标准应契合规则。
(2) Under the maximum allowable installation interval of air duct, the minimum standard of hanger shall conform to the rules.
(3)支吊架预埋件应装置准确，且要结实牢靠，其埋入有些应进行整理，而显露有些应进行防腐处理。
(3) The embedded parts of supports and hangers shall be installed accurately and firmly. Some embedded parts shall be arranged, while others exposed shall be treated with anti-corrosion.
(4)支吊架不宜设在设备的操作部位，对支吊架进行固定时，应运用胀锚螺栓进行固定，胀锚螺栓的运用应契合规则请求。
(4) The support and hanger should not be set in the operation part of the equipment. When fixing the support and hanger, the expansion anchor bolt should be used for fixation, and the application of the expansion anchor bolt should meet the requirements of the rules.
