　　1、通风管道在运输过程应有防止损伤风管的保护措施。

　　1. Ventilation pipes should be protected against damage during transportation.

　　2、榫接风管的连接在榫口处涂胶粘剂，是为增强接头处的强度。

　　2. The connection of tenon-joint air duct is coated with adhesive at the tenon-joint to enhance the strength of the joint.

　　3、当风管采用地面预组装后架空安装时，限制预组装的长度是为了遮免风管因自重产生的弯曲而破坏构件接口。

　　3. When air ducts are installed overhead after ground pre-assembly, the length of pre-assembly is limited in order to prevent the bending of air ducts caused by self-weight from destroying component interfaces.

　　4、玻璃纤维复合板风管端口为切割面时，在装配法兰连接件前应将管端切口面用胶带或胶液进行封堵，才能防止玻璃纤维外露和飞散。

　　4. When the end of glass fiber composite board air duct is cut face, before assembling flange connector, the end of the pipe should be sealed with tape or glue to prevent the glass fiber from exposing and flying away.

　　5、非法兰连接的玻璃纤维复合板风管垂直安装的支撑件制作与安装的方法。

　　5. The method of making and installing the supporting parts for the vertical installation of the glass fibre composite board air duct connected by illegal blue.

　　6、竖井内通风管道垂直安装，由于空间少，又不便于以后检修，故风管一般采用外套角钢法兰连接以增加连接点的牢固程度和强度，并把法兰作成“井”形，吊筋直接吊在角钢法兰的吊耳上而不另设支撑件。

　　6. Vertical installation of ventilation pipes in vertical shaft, due to the lack of space and the inconvenience of later maintenance, so the air duct generally adopts the outer angle steel flange connection to increase the firmness and strength of the connection points, and the flange is made into a "well" shape, and the suspension bar is directly suspended on the lifting lug of the angle steel flange without additional supporting parts.

　　风管安装加工是将法兰的槽口套插在风管管板的端头，用胶粘剂粘接。如果其间没有过盈量，槽口和风管端面插入时会有一定的间隙，使其无法粘为一体。

　　The installation and processing of the air duct is to insert the slot sleeve of the flange into the end of the air duct plate, and to bond it with adhesive. If there is no interference between them, there will be some gap between the groove and the end face of the air duct when inserting, which makes it impossible to stick together.

　　通风设备的安装质量更是影响到空气的交换

　　The installation quality of ventilation equipment affects air exchange.

　　1、做好施工前的准备工作

　　1. Preparing for construction

　　俗话说“磨刀不误砍柴工”，充分的准备工作是确保风管安装质量的前提。在准备净化风管的制作时，无论是采取工厂集中制作还是现场制作方式，都必须保证场地的洁净和封闭，并拥有符合条件的采光和照明条件。除此外，还要对制作好的方管进行看管，尽量避免污染。

　　As the saying goes, "no mistake in cutting firewood by sharpening knives", adequate preparation is the premise to ensure the installation quality of air ducts. When preparing for the production of purified air ducts, whether centralized production in factories or on-site production, it is necessary to ensure that the site is clean and closed, and has the lighting and lighting conditions that meet the requirements. In addition, we should also take care of the square tubes made to avoid pollution as far as possible.

　　2、风管材质的选择

　　2. Selection of Air Pipe Material

　　风管材质的选择，对风管的施工质量也有很大的影响。一般而言为了保证风管的重量，需采用较小板厚的风管，但除此外还需要综合考虑风管的尺寸和压力级别。从设计角度来看，值得注意的是一个系统可以同时存在几种对应于不同静压级别的风管板厚。

　　The selection of air duct material also has a great influence on the construction quality of air duct. Generally speaking, in order to ensure the weight of the duct, the minimum thickness of the duct is needed, but in addition, the size and pressure level of the duct need to be considered comprehensively. From the design point of view, it is worth noting that there are several duct sheet thicknesses corresponding to different static pressure levels in a system at the same time.

　　3、风管的横向连接

　　3. Horizontal connection of air duct

　　风管的横向连接有一定讲究，这种连接方式可以说是是延续风管长度的一种手段，还具备增强刚度及保持风管精确地横向尺寸的作用。通常横向连接的方式是角钢法兰连接，这种连接方式取决于壁厚，更取决于连接种类及板壁加固方式。

　　The horizontal connection of air duct is particular. It can be said that this connection is a means to extend the length of air duct. It also has the function of enhancing stiffness and keeping accurate lateral dimension of air duct. Usually the way of lateral connection is angle steel flange connection, which depends on the thickness of the wall, but also depends on the type of connection and the way of plate wall reinforcement.

　　4、风管的纵向缝接合

　　4. Longitudinal seam joint of air duct

　　风管的纵向缝接合方式可以根据实际情况，选择对应的方式。在中、低压风管中常常使用扣式咬口连接，对于矩形风管，联合咬口使用无任何压力级别，因此使用扣式咬口可以节省一道翻边工序，目前大多数的风管纵向缝接合都采用了扣式咬口。对于立缝和封盖式立缝可以使用铆钉、自攻螺丝、点焊、压凸凹痕等方法紧固。

　　The longitudinal joint mode of air duct can be selected according to the actual situation. Button bite connection is often used in middle and low pressure air ducts. For rectangular air ducts, there is no pressure level for joint bite. Therefore, using buckle bite can save a flanging process. At present, buckle bite is used in most longitudinal seam joints of air ducts. Rivets, tapping screw, spot welding and indentation can be used to fasten the vertical seam and capping vertical seam.

　　5、风管的存放

　　5. Storage of air ducts

　　预制好的风管，是必须要做好存放工作，以免受到二次污染。可将管口用塑料布等密封材料封住，然后将风管分门别类堆放好。在使用风管前，要注意进行彻底的清洗工作，确定板材表面无腐蚀，干燥后不吸尘。

　　Prefabricated air ducts must be stored well to avoid secondary pollution. The nozzle can be sealed with plastic cloth and other sealing materials, and then the air ducts can be stacked in different categories. Before using the air duct, we should pay attention to thorough cleaning work to ensure that there is no corrosion on the surface of the sheet and no dust absorption after drying.
