　　在建筑業(yè)快速發(fā)展的現(xiàn)在，高層建筑越來越多，為了保護(hù)在內(nèi)工作人員的身體健康，通風(fēng)管道的運(yùn)用也多了起來，在給通風(fēng)管道加工時，有很多事項要注意，下面主要是一些常見的問題：

　　With the rapid development of the construction industry, there are more and more high-rise buildings. In order to protect the health of staff members, the use of ventilation pipes has increased. When processing ventilation pipes, there are many things to pay attention to. The following are mainly some common problems:

　　通風(fēng)管道加工的過程中應(yīng)該盡量避免出現(xiàn)縱向接縫，但是不能出現(xiàn)橫向接縫。而且通風(fēng)管道的咬口縫和四角的縫隙處，需要按照設(shè)計潔凈等級要求，然后還要采用密封膠將其堵嚴(yán)。另外通風(fēng)管道板材的連接縫的密封面應(yīng)該設(shè)在通風(fēng)管道壁的正壓側(cè)。

　　Longitudinal joints should be avoided as far as possible in the process of ventilation pipeline processing, but transverse joints should never appear. Moreover, the bite seam and the corner seam of the ventilation pipeline need to be sealed with sealant according to the requirements of the design cleanliness grade. In addition, the sealing surface of the connection joint of the ventilation pipe sheet should be located at the positive pressure side of the ventilation pipe wall.

　　加工的時候，不能在通風(fēng)管道內(nèi)部設(shè)置加固框或者加固筋，因為這樣對于通風(fēng)管道的質(zhì)量會造成一定的影響。

　　When processing, it is not possible to set reinforcement frames or reinforcement bars inside the ventilation pipeline, because this will have a certain impact on the quality of the ventilation pipeline.

　　通風(fēng)管道加工不能采用S型插條和C型直角插條的連接方式，另外對于一些特殊的通風(fēng)管道來說，還不能采用按扣式的咬口。

　　The connection of S-type and C-type right-angle slots can not be used in the processing of ventilation pipes. In addition, for some special ventilation pipes, the button-type bite can not be used.

　　通風(fēng)管道制作完畢之后，還要用清洗液進(jìn)行清洗，只有達(dá)到清洗標(biāo)準(zhǔn)之后，才可以及時封口。

　　After the production of ventilation pipes, they should be cleaned with cleaning fluid. Only after meeting the cleaning standards, can they seal in time.

　　如果是彩色涂層鋼板通風(fēng)管道的話，應(yīng)該保持內(nèi)壁是光滑的，而且通風(fēng)管道加工的過程中，還不能將涂層損壞，若是出現(xiàn)損壞的部位，需要用環(huán)氧樹脂涂刷在表面即可。另外通風(fēng)管道加工的過程中，還要做好防腐蝕措施，不能使用抽芯鉚釘，而且在通風(fēng)管道零件裝配的時候，這些零件都要經(jīng)過鍍鋅處理才行。

　　If it is a color coated steel ventilation pipe, the inner wall should be kept smooth, and in the process of ventilation pipe processing, the coating can not be damaged, if there are damaged parts, it is necessary to use epoxy resin to coat the surface. In addition, anti-corrosion measures should be taken in the process of ventilation pipeline processing. Core-pulling rivets should not be used. Moreover, when the parts of ventilation pipeline are assembled, they must be galvanized.

　　管道通風(fēng)中的的噪音控制方法

　　Noise Control Method in Pipeline Ventilation1、防火功用好：其時普遍存在的問題是制品通風(fēng)道燃燒功用和耐火極限未經(jīng)有關(guān)部門檢測，且部分通風(fēng)道材料的燃燒功用、管壁厚度不符合要求。

　　1. Good fireproof function: At that time, the common problem was that the burning function and fireproof limit of product ventilation duct had not been inspected by relevant state departments, and the burning function and wall thickness of some ventilation duct materials did not meet the requirements.

　　2、造價低：通風(fēng)管道與傳統(tǒng)磚砌通風(fēng)道比，能節(jié)約工程造價40%左右;3、輕質(zhì)高強(qiáng)：與傳統(tǒng)磚砌通風(fēng)道比，菱鎂通風(fēng)道自重輕、強(qiáng)度高，能大幅度下降建筑物的承受荷載;4、規(guī)劃活絡(luò)：通風(fēng)管道可根據(jù)預(yù)留洞的巨細(xì)，隨時調(diào)整管道的標(biāo)準(zhǔn)標(biāo)準(zhǔn);5、規(guī)劃一起：通風(fēng)管道的開口上裝置了煙氣止回閥和防火阻隔門，可以有用防止串味和串火;6、施工簡略：增加了室內(nèi)空間，密閉性好、不返煙、不返臭，能大幅度改進(jìn)室內(nèi)環(huán)境。

　　2. Low cost: ventilation duct can save about 40% of the project cost compared with traditional brick ventilation duct; 3. Light weight and high strength: compared with traditional brick ventilation duct, magnesite ventilation duct has light weight and high strength, which can greatly reduce the bearing load of buildings; 4. Planning flexible network: ventilation duct can adjust the standard standard of pipeline at any time according to the size of the reserved tunnel; 5. Planning together: ventilation duct's design A smoke check valve and a fire barrier door are installed on the opening to prevent cross-odor and cross-fire. 6. The construction is simple: the indoor space is increased, the airproof is good, the smoke and odor are not returned, and the indoor environment can be greatly improved.

　　螺旋風(fēng)管在作業(yè)進(jìn)程會發(fā)生必定的噪音，假定在住宅區(qū)和商業(yè)區(qū)會對人們的日子發(fā)生很大的影響。那么我們在施工進(jìn)程中怎么削減噪音呢？

　　The helical duct will produce certain noise in the process of operation, assuming that in residential and commercial areas will have a great impact on people's lives. So how do we reduce noise in the construction process?

　　通風(fēng)管道體系作業(yè)噪音一般來源于以下幾個方面:

　　The working noise of ventilation duct system generally comes from the following aspects:

　　風(fēng)管的顫動。因為風(fēng)管材料是鍍鋅板或者是金屬材料，在施工時要嚴(yán)峻按照施工檢驗標(biāo)準(zhǔn)選擇鋼板厚度和施工工藝，比如風(fēng)管制作差錯、平直度、風(fēng)管加固、支吊架選擇及制作設(shè)備等等。到了施工階段，出風(fēng)口盡量不要挨近設(shè)備。電扇前后盡量都有5米以上的長度。假定可以增加彎頭數(shù)目也可以下降噪音，風(fēng)口加裝過濾網(wǎng)，噪音操控作用也很好。

　　Flutter of air duct. Because the material of air duct is galvanized sheet or metal material, the thickness of steel plate and construction technology should be strictly selected according to construction inspection standards, such as air duct errors, flatness, air duct reinforcement, support and hanger selection and production equipment, etc. At the construction stage, the outlet should not be close to the equipment as far as possible. The length of the electric fan should be more than 5 meters before and after it. It is assumed that the number of elbows can be increased and the noise can be reduced. A filter is installed in the tuyere, and the noise control function is also very good.

　　風(fēng)機(jī)的動靜。處理方法我們一般可裝消聲器處理風(fēng)管zhong風(fēng)的沖突聲。一般在規(guī)劃階段就要考慮噪聲的問題，規(guī)劃操控好管內(nèi)風(fēng)速，防止風(fēng)聲嘯叫以下是一些履歷。

　　The movement of the fan. In general, we can install mufflers to deal with the conflict sound of wind pipe zhong. In general, the problem of noise should be considered in the planning stage. To control the wind speed in the pipe and prevent the wind from screaming, the following are some resumes.

　　1操控出風(fēng)、回風(fēng)間隔，防止空氣對流時自激表象和小循環(huán)空間。

　　1. Manipulate the air outlet and return interval to prevent self-excitation and small circulation space during air convection.

　　2、螺旋風(fēng)管風(fēng)機(jī)葉輪體系動平衡校調(diào)合理正常正負(fù)不大于5絲的高低。

　　2. The dynamic balance adjustment of the impeller system of the spiral duct fan is reasonable and the positive and negative values are not more than 5 wires.

　　3、軟接頭設(shè)備標(biāo)準(zhǔn)，防止軟接帆布松垮發(fā)生風(fēng)阻而形成風(fēng)噪。

　　3. Standard of soft joint equipment to prevent wind resistance from loosening of soft joint canvas and wind noise.

　　4、懸掛選用趁便繃簧避震專職的連接器，減輕作業(yè)時因扭力發(fā)生的跳動或共頻。

　　4. The suspension adopts the full-time connector of the tension spring shock absorber to alleviate the jump or common frequency caused by the torsion during the operation.

　　5、螺旋風(fēng)管風(fēng)道轉(zhuǎn)角盡量削減。

　　5. Reduce the angle of helical duct as far as possible.
