The thick steel plate round air duct is connected with the stainless steel air duct. First, the two sides of each pipe are rolled out with ribs, and one end of each pipe is reduced to a hole. When installing the equipment, insert the opening into the small opening according to the cyclone direction, use the steel hoop to tightly connect the drum hoops on both sides, and finally use the anchor bolt to wear it in the middle of the earrings to fix and tighten.
What should you pay attention to when you introduce the anti-seismic support of ventilation duct
1. The form, material, production and processing specification, installation interval, manufacturing precision and electric welding of the anti-seismic support for ventilation pipe shall meet the requirements of the design scheme, and shall not be changed at will. It is necessary to use bench drill or hand drill for drilling, and oxyacetylene flame shall not be used for drilling
2. The screw rod steel of the anti-seismic support should be extracted according to the design elevation of the air duct installation. The sleeve wire is not suitable to be too long, the end of the wire mouth is not suitable to exceed the fixed support value, and the ventilation pipe in Shandong Province should not hinder the construction of the ceiling decoration project
3. The screw rod of seismic support shall be vertical, and the external thread shall be intact and bright
4. After the anti-seismic support of ventilation pipe is manufactured, the anti-corrosion treatment shall be interrupted, and then the anti-corrosion paint shall be painted twice, and then the dark gray paint shall be painted twice. The position buried in the wall and concrete shall not be painted
5. When the rectangular frame metal material level ventilation duct has a large allowable installation distance, the small specification of the support should meet the standard. When the ring metal material level ventilation duct has a large allowable installation distance in Shandong Province, the small specification of the support should meet the standard. The key is to connect the ventilation duct with components (such as heat pipe radiator, positive pressure air supply outlet on the side of static pressure box, etc.). When using the equipment, both sides of the plastic hose are sheathed in the connecting pipe, and then the plastic hose is clamped tightly with a particularly soft clamp.
