Gas fire-extinguishing explosion-proof light partition wall system

A gas fire-extinguishing explosion-proof light partition wall system comprises a keel frame, fireproof gypsum board layers mounted on two lateral faces of the keel frame, and mineral wool is arranged inside the keel frame. The keel frame comprises an along-top keel, an along-floor keel, horizontal keels and vertical keels, wherein the along-top keel and the along-floor keel are respectively fixedly connected to a top beam and the ground through fasteners, lateral edges of the along-top keel and the along-floor keel are provided with angle irons which are mounted on the back sides of stressed faces, and one edge of each angle iron is connected with the top beam or the ground while other edge is attached to the gypsum board layer. Crack resistant wall cloth is adhered to the outer surface of each gypsum board layer. The light partition wall system has the advantages of thick wall body, fine sound insulating effect, strong stability, high fire resistance limit and strong instant explosion resistance.
