Novel respiratory type curtain wall system

The invention discloses a novel respiratory type curtain wall system, and relates to green buildings. The problem that loosening between a connecting piece and an outer layer curtain wall easily occurs in a long-term use process so as to result in larger safety hidden dangers is solved. The novel respiratory type curtain wall is characterized by comprising prefabricated pieces horizontally embedded in a wall body positioned between floors, wherein parts, penetrating through the wall body, of the prefabricated pieces are fixedly connected with mounting pieces; the mounting pieces are arranged on the surface of a longitudinal wall body; each of the mounting piece comprises first fixing parts which are symmetrical to each other and second fixing parts which are symmetrical to each other; thefirst fixing parts are connected with inner fixing pieces and are connected with inner-layer glass through the inner fixing parts; and one end, facing the outer side of the wall body, of the corresponding second fixing part is connected with an outer fixing piece and is connected with outer-layer glass through outer fixing pieces; and the outer fixing pieces are provided with connection clamping legs, and connection clamping grooves connected with the connection clamping legs in a clamping manner are formed in the second fixing parts, so that the stability of the connection between the prefabricated pieces and the outer-layer curtain wall can be improved.
