1. The planning of supports and hangers for fans, air conditioning units, fan panels, and other equipment requires the provision of vibration isolators, and their types and specifications should meet the requirements of the planning and product technology documents.

2、風(fēng)管筆直設(shè)備，間隔不該大于4m，單根直管起碼應(yīng)有2個(gè)不變點(diǎn)。

2. The equipment with straight air ducts should have a spacing of no more than 4m, and a single straight duct should have at least 2 fixed points.

3、吊架的螺孔應(yīng)選用機(jī)械加工，吊桿應(yīng)平直，螺紋無(wú)缺、光亮。

3. The screw holes of the suspension bracket should be machined, and the suspension rod should be straight, with no missing or bright threads.

4、長(zhǎng)度超出20m的水平懸吊風(fēng)管，在通風(fēng)管道施工時(shí)起碼配備1個(gè)防晃支架。

4. Horizontal suspended air ducts exceeding 20m in length should be equipped with at least one anti shaking support during the construction of ventilation ducts.

5、支吊架不宜配備在風(fēng)口、閥門(mén)、查驗(yàn)門(mén)及自控組織處，離風(fēng)口或插接納的間隔不宜小于200mm。

5. Supports and hangers should not be installed at air vents, valves, inspection doors, and automatic control organizations, and the distance between them and the air vents or plugs should not be less than 200mm.

6、平懸吊的主、干風(fēng)管長(zhǎng)度超出20m時(shí)應(yīng)配備防備搖擺的不變點(diǎn)，每個(gè)體系不該少于1個(gè)。

6. When the length of the main and main air ducts suspended horizontally exceeds 20m, they should be equipped with fixed points to prevent swaying, and each system should not be less than 1.

7、風(fēng)管支吊架宜按國(guó)標(biāo)圖集與規(guī)范選用強(qiáng)度和剛度相適宜的模式和規(guī)范，關(guān)于直徑或邊長(zhǎng)大于2500㎜的超寬、超重風(fēng)管的支、吊架應(yīng)按規(guī)劃規(guī)章。

7. The support and hanger of air ducts should be selected according to the national standard atlas and specifications with suitable strength and stiffness modes and specifications. For support and hanger of ultra wide and overweight air ducts with a diameter or side length greater than 2500 mm, planning regulations should be followed.

8、設(shè)備后各副支、吊架的受力應(yīng)均勻，無(wú)顯著變形，風(fēng)管或空調(diào)設(shè)備運(yùn)用的可調(diào)隔振支、吊架的拉伸或收縮量應(yīng)按規(guī)劃的要求進(jìn)行調(diào)度。

8. The force on each auxiliary support and hanger behind the equipment should be uniform without significant deformation. The adjustable vibration isolation support and hanger used for air ducts or air conditioning equipment should be adjusted for stretching or shrinking according to the planned requirements.

因此，在規(guī)劃通風(fēng)管道時(shí)，正確安置和挑選結(jié)構(gòu)適宜的支吊架，能夠改進(jìn)通風(fēng)管道的應(yīng)力分散，確保通風(fēng)管道的平安作業(yè)，還能夠拉長(zhǎng)通風(fēng)管道的運(yùn)用壽數(shù)。

Therefore, when planning ventilation ducts, the correct placement and selection of structurally suitable supports and hangers can improve the stress dispersion of the ventilation ducts, ensure safe operation of the ventilation ducts, and also extend the service life of the ventilation ducts.
