The invention relates to a protection device for enhancing the air near-field explosion resistance of an existing building. The protection device comprises a splicing outer frame and a protection unit embedded in the splicing outer frame, wherein the protection unit comprises a first honeycomb steel plate unit and a second honeycomb steel plate unit which are attached together; the first honeycomb steel plate unit comprises a first fixed box and first honeycomb cells fixed in the first fixed box; the second honeycomb steel plate unit comprises a second fixed box and second honeycomb cells fixed in the second fixed box; the first honeycomb cells are axially and vertically arranged; the second honeycomb cells are axially and transversely arranged; CFRP protection layers are symmetrically arranged on the side walls, away from each other, of the first fixed box and the second fixed box; and the first honeycomb cells and the second honeycomb cells are filled with high polymers. Shock waves are attenuated and absor
