The two side surfaces 202 of the rectangular groove are close to the two side surfaces of the duct plate body 100, and the bottom surface 203 of the rectangular groove is close to the thickness surface of the duct plate body 100.

[0043] In a preferred embodiment, the edge-wrapped connector 200 is an integrally connected structure and can be manufactured by extrusion molding, which is convenient to process, has high processing efficiency and low cost.

[0044] In a preferred embodiment, the edging connector 200 is made of metal material, such as inert iron sheet.

[0045] In a preferred embodiment, the air duct plate body 100 is made of non-metallic material, such as calcium silicate board.

[0046] In a preferred embodiment, the modular prefabricated air duct plate further comprises:

[0047] The plate fixing member 300 is used to fix the duct plate body 100 and the edge connecting member 200 .
