Ventilation duct is very important in urban construction, especially its installation quality is also harmful to gas exchange, all normal "theme activities" and work efficiency. Today, the ventilation duct enterprises in Shanxi Province will introduce in detail which factors can endanger the installation quality of ventilation ducts.

1、搞好工程施工前的准备工作

1. Do a good job of preparation before construction

俗话说得好“胜不骄败不馁”，充足的准备工作是保证风管安装品质的前提条件。在提前准备净化处理风管的制做时，不论是采用加工厂集中化制做或是当场制做方法，都务必确保场所的清洁和封闭式，并有着满足条件的光照和照明灯具标准。除此外，还需要对制做好的方钢管开展照看，尽量减少环境污染。

As the saying goes, "victory is not arrogant, defeat is not discouraged". Sufficient preparation is the prerequisite to ensure the installation quality of air duct. When preparing the fabrication of purification treatment air duct in advance, whether it is centralized in the processing plant or on the spot, it is necessary to ensure that the place is clean and closed, and there are lighting and lighting standards that meet the conditions. In addition, it is also necessary to take care of the prepared square steel pipe to minimize environmental pollution.

2、风管材料的挑选

2. Selection of air duct materials

风管材料的挑选，对风管的施工质量也是有非常大的危害。一般而言为了更好地确保风管的净重，需选用少板厚的风管，但除此外还需要综合性考虑到风管的规格和工作压力等级。从设计方案视角看来，特别注意的是一个系统软件能够 另外存有几类相匹配于不一样负压等级的风管板厚。

The selection of air duct materials is also very harmful to the construction quality of air duct. Generally speaking, in order to better ensure the net weight of the air duct, the air duct with less plate thickness needs to be selected, but in addition, the specification and working pressure grade of the air duct need to be comprehensively considered. From the perspective of design scheme, special attention should be paid to that a system software can store several types of air duct plate thickness matching different negative pressure levels.

3、风管的横着联接

3. Transverse connection of air duct

风管的横着联接有一定注重，这类接口方式可以说是是持续风管长短的一种方式，还具有提高弯曲刚度及维持风管地横着规格的功效。一般 横着联接的方法是角铁活套法兰，这类接口方式在于壁厚，更在于联接类型及板壁结构加固方法。

There is a certain emphasis on the transverse connection of the air duct. This kind of interface mode can be said to be a way to maintain the length of the air duct. It also has the effect of improving the bending stiffness and maintaining the transverse specification of the air duct. Generally, the method of transverse connection is angle iron looper flange. This kind of interface mode depends on the wall thickness, but also on the connection type and the reinforcement method of plate and wall structure.

4、风管的竖向缝紧密连接

4. The vertical joints of air ducts are closely connected

风管的竖向缝紧密连接方法能够 依据具体情况，挑选相匹配的方法。在中国、底压风管中经常应用扣式咬口联接，针对矩形框风管，协同压槽应用无一切工作压力等级，因而应用扣式咬口能够 节约一道反边工艺流程，现阶段大部分的风管竖向缝紧密连接都选用了扣式咬口。针对立缝和密封式立缝能够 应用螺栓、自攻螺钉、焊接、压凹凸痕等方式 拧紧。

The vertical joint tight connection method of air duct can select the matching method according to the specific situation. In China, button type undercut connection is often used in bottom pressure air ducts. For rectangular frame air ducts, there is no working pressure level in the application of cooperative pressure groove. Therefore, the application of button type undercut can save a reverse edge process. At this stage, button type undercut is selected for the close connection of most vertical joints of air ducts. For vertical joints and sealed vertical joints, bolts, self tapping screws, welding, indentation and other methods can be used to tighten.

5、风管的储放

5. Storage of air duct

预制构件好的风管，是务必要搞好储放工作中，以防遭受二次污染。可将支管用塑料薄膜等橡胶密封件封死，随后将风管分门别类堆积好。在应用风管前，要留意开展完全的清理工作中，明确板才表面耐腐蚀，干躁后不除尘。

The air duct with good prefabricated components must be stored well to prevent secondary pollution. The branch pipe can be sealed with rubber seals such as plastic film, and then the air duct can be stacked by category. Before applying the air duct, pay attention to carry out complete cleaning work, make it clear that the surface of the plate is corrosion-resistant, and do not remove dust after dryness.
