熱鍍鋅通風(fēng)管在城市建設(shè)中占據(jù)關(guān)鍵影響力。
Hot dip galvanized ventilation pipe occupies a key influence in urban construction.
1.工程施工前的提前準(zhǔn)備
1. Preparation before construction
俗話說(shuō)得好“磨刀技巧不誤劈柴功”。充足的提前準(zhǔn)備是確保風(fēng)管安裝品質(zhì)的前提條件。凈化處理風(fēng)管提前準(zhǔn)備生產(chǎn)制造時(shí)，不論是廠內(nèi)集中化生產(chǎn)制造或是當(dāng)場(chǎng)生產(chǎn)制造，都需要確保當(dāng)場(chǎng)清理封閉式，有達(dá)標(biāo)的照明燈具和照明燈具標(biāo)準(zhǔn)。此外，生產(chǎn)加工好的方鋼管應(yīng)當(dāng)心運(yùn)送，盡量減少環(huán)境污染。
As the saying goes, "the skill of sharpening a knife does not miss the skill of chopping firewood". Adequate preparation in advance is the prerequisite to ensure the installation quality of air duct. When the purification treatment air duct is prepared for production and manufacturing in advance, whether it is centralized production and manufacturing in the plant or on the spot production and manufacturing, it is necessary to ensure that the closed type is cleaned on the spot and there are standard lighting lamps and lighting lamps. In addition, the produced and processed square steel pipes should be transported carefully to minimize environmental pollution.
2.管道原材料的挑選
2. Selection of pipeline raw materials
風(fēng)管原材料的挑選對(duì)風(fēng)管的施工質(zhì)量也是有非常大的危害。一般來(lái)說(shuō)，為了更好地確保風(fēng)管的凈重，務(wù)必選用厚度較小的風(fēng)管，但風(fēng)管的規(guī)格和工作壓力級(jí)別務(wù)必綜合性考慮到。從設(shè)計(jì)方案的視角看來(lái)，特別注意的是，一個(gè)系統(tǒng)軟件能夠 幾個(gè)筒體薄厚相匹配不一樣的負(fù)壓水準(zhǔn)。
The selection of air duct raw 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 smaller thickness must be selected, but the specification and working pressure level of the air duct must be comprehensively considered. From the perspective of design scheme, it should be noted that a system software can match the thickness of several cylinders with different negative pressure levels.
3.風(fēng)管水準(zhǔn)聯(lián)接
3. Horizontal connection of air duct
風(fēng)管水準(zhǔn)聯(lián)接有一定的獨(dú)特性。這類(lèi)接口方式能夠 說(shuō)成增加風(fēng)管長(zhǎng)短的方式，還具備提高風(fēng)管彎曲剛度、維持風(fēng)管水準(zhǔn)規(guī)格的功效。水準(zhǔn)聯(lián)接一般 是角活套法蘭。這類(lèi)聯(lián)接在于墻面的薄厚，也在于墻面的聯(lián)接和加固。
The horizontal connection of air duct has certain uniqueness. This kind of interface mode can be described as a way to increase the length of the air duct, and also has the effect of improving the bending stiffness of the air duct and maintaining the standard specification of the air duct. Horizontal connection is generally angle looper flange. This kind of connection lies not only in the thickness of the wall, but also in the connection and reinforcement of the wall.
4.風(fēng)管縱縫
4. Longitudinal joint of air duct
風(fēng)管縱縫方式可依據(jù)具體情況挑選。中底壓管道中常會(huì)選用扣子牙齒咬合聯(lián)接。針對(duì)矩形框管道，沒(méi)有連接頭堵塞的工作壓力等級(jí)。因而，選用扣子牙齒咬合能夠 節(jié)約反邊工藝流程?，F(xiàn)階段，大部分軟管是豎向接縫處。按鍵用以聯(lián)接?？蛇x用螺栓、自攻螺絲、焊接、壓紋、壓印等方式 擰緊立縫和帽型立縫。
The longitudinal joint mode of air duct can be selected according to specific conditions. The middle and bottom pressure pipes are usually connected by the bite of buttons and teeth. For rectangular box pipes, there is no working pressure level with connector blockage. Therefore, the selection of button teeth can save the reverse edge process. At this stage, most hoses are at vertical joints. The key is used to connect. Bolts, self tapping screws, welding, embossing, embossing and other methods can be used to tighten the vertical seam and cap type vertical seam.
5.風(fēng)管儲(chǔ)放
5. Air duct storage
預(yù)制構(gòu)件風(fēng)管應(yīng)妥當(dāng)儲(chǔ)放，防止二次污染。支管可以用塑料薄膜等橡膠密封件密封性，隨后將管道歸類(lèi)堆積。風(fēng)管應(yīng)用前留意清理，保證表面耐腐蝕，干躁后無(wú)真空泵。
The air duct of prefabricated components shall be properly stored to prevent secondary pollution. The branch pipe can be sealed with rubber seals such as plastic film, and then the pipe can be classified and stacked. Pay attention to cleaning the air duct before application to ensure that the surface is corrosion-resistant, and there is no vacuum pump after dryness.
