[0002] Double-sided color steel fiberglass composite air duct is a new type of ventilation equipment, made of composite material technology. It is composed of inner and outer color steel shells, glass fiber insulation layer and other reinforcing materials. It is a ventilation equipment with the advantages of light weight, sound insulation, heat insulation, corrosion resistance, waterproof, fire resistance, and beautiful appearance. When the long side of the double-sided color steel fiberglass composite air duct is longer, screw rods are generally used to reinforce the inside of the composite air duct to make the air duct look more upright, while enhancing its ability to withstand wind pressure, ensuring that it will not collapse or be damaged during its design life, and improving safety.

[0003] In the prior art, when reinforcing a double-sided color steel fiberglass composite air duct, the outer wall needs to be perforated, a screw rod is passed through the hole, and the duct is locked and fixed by a nut and a gasket. Since the length of the screw rod is fixed, the applicability to double-sided color steel fiberglass composite air ducts of different heights is poor, and the perforation method destroys the inner and outer color steel shell structures. Therefore, we propose a double-sided color steel plate fiberglass composite air duct to solve the above problems. Utility Model Content
