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、搞好工程施工前的準(zhǔn)備工作

1. Do a good job of preparation before construction

俗話說(shuō)得好“勝不驕敗不餒”，充足的準(zhǔn)備工作是保證風(fēng)管安裝品質(zhì)的前提條件。在提前準(zhǔn)備凈化處理風(fēng)管的制做時(shí)，不論是采用加工廠集中化制做或是當(dāng)場(chǎng)制做方法，都務(wù)必確保場(chǎng)所的清潔和封閉式，并有著滿足條件的光照和照明燈具標(biāo)準(zhǔn)。除此外，還需要對(duì)制做好的方鋼管開(kāi)展照看，盡量減少環(huán)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、風(fēng)管材料的挑選

2. Selection of air duct materials

風(fēng)管材料的挑選，對(duì)風(fēng)管的施工質(zhì)量也是有非常大的危害。一般而言為了更好地確保風(fēng)管的凈重，需選用少板厚的風(fēng)管，但除此外還需要綜合性考慮到風(fēng)管的規(guī)格和工作壓力等級(jí)。從設(shè)計(jì)方案視角看來(lái)，特別注意的是一個(gè)系統(tǒng)軟件能夠 另外存有幾類(lèi)相匹配于不一樣負(fù)壓等級(jí)的風(fēng)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、風(fēng)管的橫著聯(lián)接

3. Transverse connection of air duct

風(fēng)管的橫著聯(lián)接有一定注重，這類(lèi)接口方式可以說(shuō)是是持續(xù)風(fēng)管長(zhǎng)短的一種方式，還具有提高彎曲剛度及維持風(fēng)管地橫著規(guī)格的功效。一般 橫著聯(lián)接的方法是角鐵活套法蘭，這類(lèi)接口方式在于壁厚，更在于聯(lián)接類(lèi)型及板壁結(jié)構(gòu)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、風(fēng)管的豎向縫緊密連接

4. The vertical joints of air ducts are closely connected

風(fēng)管的豎向縫緊密連接方法能夠 依據(jù)具體情況，挑選相匹配的方法。在中國(guó)、底壓風(fēng)管中經(jīng)常應(yīng)用扣式咬口聯(lián)接，針對(duì)矩形框風(fēng)管，協(xié)同壓槽應(yīng)用無(wú)一切工作壓力等級(jí)，因而應(yīng)用扣式咬口能夠 節(jié)約一道反邊工藝流程，現(xiàn)階段大部分的風(fēng)管豎向縫緊密連接都選用了扣式咬口。針對(duì)立縫和密封式立縫能夠 應(yīng)用螺栓、自攻螺釘、焊接、壓凹凸痕等方式 擰緊。

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、風(fēng)管的儲(chǔ)放

5. Storage of air duct

預(yù)制構(gòu)件好的風(fēng)管，是務(wù)必要搞好儲(chǔ)放工作中，以防遭受二次污染。可將支管用塑料薄膜等橡膠密封件封死，隨后將風(fēng)管分門(mén)別類(lèi)堆積好。在應(yīng)用風(fēng)管前，要留意開(kāi)展完全的清理工作中，明確板才表面耐腐蝕，干躁后不除塵。

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.
