Technical Field

[0001] This utility model relates to the field of air duct technology, and in particular to an irregularly shaped air duct structure. Background Technology

[0002] Air duct structures serve as the primary openings for air circulation between the interior and exterior environments. Current technologies typically utilize the corners and gaps of factory rooms to construct irregularly shaped concrete air ducts to ensure system functionality. However, excessive irregular structures can significantly complicate civil construction and negatively impact ventilation system performance (especially resistance characteristics and airtightness). Therefore, to facilitate construction and modular production while meeting the requirements for structural stability, internal cleanliness, resistance characteristics, and airtightness of air ducts, a novel irregularly shaped air duct structure is proposed.

[0005] Preferably, the main frame comprises an upper frame, a lower frame, a left frame, a right frame, and a frame structure consisting of several partitions, wherein the distances between the left frame and the partitions, the right frame and the partitions, and between two adjacent partitions are consistent.

[0006] Preferably, the air duct plate includes symmetrically arranged air duct plate supports, with an inner air duct plate and an outer air duct plate disposed between the two air duct plate supports. An inner air duct plate cover is disposed on the outer side of the inner air duct plate, and an outer air duct plate cover is disposed on the outer side of the outer air duct plate. Sound insulation filler is disposed between the inner air duct plate and the outer air duct plate.

[0007] Preferably, the air duct plate bracket, the inner side plate of the air duct plate, the inner cover plate of the air duct plate, the outer side plate of the air duct plate, and the outer cover plate of the air duct plate are fixed by welding.

[0008] Compared with traditional structures, the advantages of this utility model are: simple structure and convenient construction. By setting embedded plates, custom main frames and air duct plates on concrete walls, it can meet the requirements of air ducts for structural stability, internal cleanliness, resistance characteristics and air tightness, improve construction efficiency and save construction costs.
