The invention discloses a novel assembled light steel wall. The novel assembled light steel wall comprises a supporting frame, prefabricated wall plates and a filling material, wherein the supporting frame comprises a rectangular frame and a supporting
keel; first fixing grooves are formed in the inner side of the rectangular frame; the two ends of the supporting
keel are matched with the first fixing grooves; second fixing grooves are symmetrically formed in the two sides of the supporting
keel; the prefabricated wall plates are arranged on the inner side of the rectangular frame; and the filling material is arranged between the two
layers of prefabricated wall plates. Compared with the prior art, the novel assembled light steel wall has the advantages that (1) the height, width and thickness of wall manufacturing are not limited; (2) the surface of the wall is smooth and flat, painting is not needed, only joint positions of different materials need to be subjected to batch painting treatment through
fiber cloth, and wall grooves are not needed during water and
electricity pipeline laying; (3) operation is easy and convenient, the construction speed is high, and the construction period is shortened; and (4) the strength is high, the novel assembled light steel wall is resistant to shock, fire, sound and
impact, and the performance is better than that of an existing product.
