　　在建筑業快速發展的現在，高層建筑越來越多，為了保護在內工作人員的身體健康，通風管道的運用也多了起來，在給通風管道加工時，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:

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

　　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，不能在通風管道內部設置加固框或者加固筋，因為這樣對于通風管道的質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.

　　通風管道制作完畢之后，還要用清洗液進行清洗，只有達到清洗標準之后，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管道的話，應該保持內壁是光滑的，而且通風管道加工的過程中，還不能將涂層損壞，若是出現損壞的部位，需要用環氧樹脂涂刷在表面即可。另外通風管道加工的過程中，還要做好防腐蝕措施，不能使用抽芯鉚釘，而且在通風管道零件裝配的時候，這些零件都要經過鍍鋅處理才行。

　　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道燃燒功用和耐火極限未經有關部門檢測，且部分通風道材料的燃燒功用、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：通風管道與傳統磚砌通風道比，能節約工程造價40%左右;3、輕質高強：與傳統磚砌通風道比，菱鎂通風道自重輕、強度高，能大幅度下降建筑物的承受荷載;4、規劃活絡：通風管道可根據預留洞的巨細，隨時調整管道的標準標準;5、規劃一起：通風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：增加了室內空間，密閉性好、不返煙、不返臭，能大幅度改進室內環境。

　　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.

　　螺旋風管在作業進程會發生必定的噪音，假定在住宅區和商業區會對人們的日子發生很大的影響。那么我們在施工進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?

　　通風管道體系作業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:

　　風管的顫動。因為風管材料是鍍鋅板或者是金屬材料，在施工時要嚴峻按照施工檢驗標準選擇鋼板厚度和施工工藝，比如風管制作差錯、平直度、風管加固、支吊架選擇及制作設備等等。到了施工階段，出風口盡量不要挨近設備。電扇前后盡量都有5米以上的長度。假定可以增加彎頭數目也可以下降噪音，風口加裝過濾網，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.

　　風機的動靜。處理方法我們一般可裝消聲器處理風管zhong風的沖突聲。一般在規劃階段就要考慮噪聲的問題，規劃操控好管內風速，防止風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、回風間隔，防止空氣對流時自激表象和小循環空間。

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

　　2、螺旋風管風機葉輪體系動平衡校調合理正常正負不大于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、軟接頭設備標準，防止軟接帆布松垮發生風阻而形成風噪。

　　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，減輕作業時因扭力發生的跳動或共頻。

　　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、螺旋風管風道轉角盡量削減。

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