通風(fēng)管道的吊架安裝是通風(fēng)管道施工中一個重要環(huán)節(jié)，吊架安裝對管道起著支承重量、平衡介質(zhì)反力、限制位移和防止震動等作用。因此就需要施工人員了解安裝吊架的規(guī)定，才能更好的完成通風(fēng)管道施工工程，接下來帶大家了解一下通風(fēng)管道施工中吊頂安裝的規(guī)定。
The installation of hanger in ventilation pipeline is an important link in the construction of ventilation pipeline. The installation of hanger plays an important role in supporting weight, balancing medium reaction, limiting displacement and preventing vibration of pipeline. Therefore, it is necessary for the construction personnel to understand the regulations for installation of hangers, in order to better complete the construction of ventilation pipelines. Next, we will take you to understand the regulations for installation of ceiling in the construction of ventilation pipelines.
1、風(fēng)機(jī)、空調(diào)機(jī)組、風(fēng)機(jī)盤等設(shè)備的支、吊架設(shè)計(jì)要求設(shè)置隔振器，其品種、規(guī)格應(yīng)符合設(shè)計(jì)及產(chǎn)品技術(shù)文件要求。
1. Vibration isolators are required in the design of brackets and hangers of fan, air conditioning unit and fan disc. The varieties and specifications of vibration isolators should meet the requirements of design and product technical documents.
2、風(fēng)管垂直安裝，間距不應(yīng)大于4m，單根直管少應(yīng)有2個固定點(diǎn)。
2. The air duct should be installed vertically, and the distance should not be greater than 4m. A single straight duct should have at least two fixed points.
3、吊架的螺孔應(yīng)采用機(jī)械加工，吊桿應(yīng)平直，螺紋完整、光潔。
3. The screw holes of the hanger shall be machined. The hanger rods shall be straight, and the threads shall be complete and smooth.
4、長度超過20m的水平懸吊風(fēng)管，在通風(fēng)管道施工時(shí)少設(shè)置1個防晃支架。
4. Horizontal suspended air duct with length over 20 m shall be provided with at least one anti-sloshing bracket during the construction of the ventilation duct.
5、支吊架不宜設(shè)置在風(fēng)口、閥門、檢查門及自控機(jī)構(gòu)處，離風(fēng)口或插接管的距離不宜小于200mm。
5. The support and hanger should not be set at the tuyere, valve, inspection door and automatic control mechanism, and the distance from the tuyere or intubation pipe should not be less than 200 mm.
6、平懸吊的主、干風(fēng)管長度超過20m時(shí)應(yīng)設(shè)置防止擺動的固定點(diǎn)，每個系統(tǒng)不應(yīng)少于1個。
6. When the length of main and dry air ducts of horizontal suspension exceeds 20m, fixed points should be set to prevent swing, and each system should not be less than one.
7、風(fēng)管支吊架宜按國標(biāo)圖集與規(guī)范選用強(qiáng)度和剛度相適應(yīng)的形式和規(guī)格，對于直徑或邊長大于2500㎜的超寬、超重特殊風(fēng)管的支、吊架應(yīng)按設(shè)計(jì)規(guī)定。
7. The support and hanger of air duct should be selected according to the form and specifications of strength and stiffness in accordance with the national standard atlas and specifications, and the support and hanger of extra-wide and extra-heavy special air duct with diameter or edge longer than 2500_should be designed according to the regulations.
8、安裝后各副支、吊架的受力應(yīng)均勻，無明顯變形，風(fēng)管或空調(diào)設(shè)備使用的可調(diào)隔振支、吊架的拉伸或壓縮量應(yīng)按設(shè)計(jì)的要求進(jìn)行調(diào)整。
8. After installation, the force of each auxiliary support and hanger should be uniform without obvious deformation. The tension or compression of the adjustable vibration isolation support and hanger used in air duct or air conditioning equipment should be adjusted according to the design requirements.
因此，在設(shè)計(jì)通風(fēng)管道時(shí)，合理布置和正確選擇結(jié)構(gòu)合適的支吊架，能夠改善通風(fēng)管道的應(yīng)力分布，確保通風(fēng)管道的運(yùn)行，還能夠延長通風(fēng)管道的使用壽命，以上就是為大家總結(jié)的安裝吊架的相關(guān)規(guī)定，希望能夠?qū)δ兴鶐椭?/div>
Therefore, in the design of ventilation pipelines, reasonable layout and correct selection of structurally appropriate support and hanger can improve the stress distribution of ventilation pipelines, ensure the safe operation of ventilation pipelines, and also extend the service life of ventilation pipelines. The above is the relevant provisions for the installation of hangers summarized by everyone, hoping to be helpful to you.
