复合风管的设备工艺
Equipment process of composite air duct
1．按规划图纸承认风管设备的标高、走向，设备吊筋，吊筋可选用胀大螺栓固定。
1. According to the planning drawings, recognize the elevation and direction of the air duct equipment, and use expansion bolts to fix the equipment suspension bars.
2．吊筋的间隔根据风管的截面承认。
2. The spacing of the hanging bars is recognized based on the cross-section of the air duct.
3．把预制合格的风管运用供应的专用法兰插条把风管联接在一起
3. Connect the prefabricated qualified air ducts together using the supplied special flange inserts
4．调整吊筋螺栓，使托盘与风管触摸严密，托盘受力均匀。
4. Adjust the hanging bar bolts to ensure that the tray and air duct touch tightly and the tray is evenly stressed.
5.风管设备前应对已制造风管进行漏光试验，抽样10%，发现漏光点超越规范要求，应对加工工艺进行改善，提高加工质量。并对原已经成型的次品应返工或报废。
5. Before installing the air duct equipment, a light leakage test should be conducted on the manufactured air duct. A sample of 10% was taken, and it was found that the light leakage point exceeded the standard requirements. The processing technology should be improved to improve the processing quality. And the original formed defective products should be reworked or scrapped.
6.复合板制成的风管重量很轻(约7kg/㎡),在设备、吊装上与传统的风管比较便利快捷。
The weight of the air duct made of composite panels is very light (about 7kg/㎡), making it more convenient and efficient in equipment and lifting compared to traditional air ducts.
7.吊装系统：承受风管系统的物体要有承受风管负荷的能力，根据承受负荷物体的种类（混凝土、加气砖或钢结构件上）可用胀大螺丝、螺栓或焊接与吊杆联接。吊杆选用镀锌杆、镀锌条均可。
7. Hoisting system: The object that bears the air duct system must have the ability to bear the load of the air duct. According to the type of object that bears the load (on concrete, aerated bricks, or steel structural components), it can be connected to the suspension rod with enlarged screws, bolts, or welding. The suspension rod can be either galvanized or galvanized.
8.管道角挂钩：挂钩一般用于边长小于600mm的直管。挂钩带有双面胶带，可快速联接，挂钩心须成对设备。
8. Pipe angle hook: The hook is generally used for straight pipes with a side length of less than 600mm. The hook is equipped with double-sided tape for quick connection, and the hook core must be paired with equipment.
9.风管的吊装除运用专用吊装挂钩加吊杆外，也能够按一般镀锌板风管的吊装方法用角钢横梁加圆钢吊杆。
9. In addition to using specialized lifting hooks and suspension rods, the lifting of air ducts can also be carried out using angle steel beams and round steel suspension rods according to the general lifting method of galvanized sheet air ducts.
10.吊装间隔：当风管长边≤400mm时，风管长边＞400mm时，吊架间隔为3m，风管长边＞800mm时，吊架间隔为2～1.5m。
10. Hoisting interval: When the long side of the air duct is ≤ 400mm and the long side of the air duct is>400mm, the hanger interval is 3m. When the long side of the air duct is>800mm, the hanger interval is 2-1.5m.
11.横梁角钢规范:当矩形风管长边≤630mm时,可用L25*3角钢，长边＞630mm时，可用L30*4角钢。
11. Cross beam angle steel specification: When the long side of the rectangular air duct is ≤ 630mm, L25 * 3 angle steel can be used, and when the long side is>630mm, L30 * 4 angle steel can be used.
12.吊杆规范：当选用L25角钢横梁时，用φ6mm圆钢，当选用L30*4角钢横梁时，可用φ8mm圆钢做吊杆。
12. Hanger specifications: When using L25 angle steel crossbeam, use φ 6mm round steel, available when using L30 * 4 angle steel crossbeam φ 8mm round steel for suspension rod.
