The invention discloses a standardized unit fabricated composite wall. The standardized unit fabricated composite wall comprises an outer wall surface, frameworks and an inner wall surface. The outer wall surface comprises an outer wall facing layer, an outer wall reflective
thermal insulation film and a one-way
breathing damp-proof layer, the inner wall surface comprises an inner wall sound absorbing layer and an inner wall facing layer, and the outer wall facing layer is manufactured by adopting a PVDF profiled steel sheet; and the positions among the frameworks are filled with rock
wool, the frame overlapping parts of the frameworks adopt first tongue-and-groove type purlines and second tongue-and-groove type purlines, and the inner wall facing layer, the inner wall sound absorbing layer, the frameworks, the outer wall reflective
thermal insulation film, the one-way
breathing damp-proof layer and the outer wall facing layer are sequentially arranged from inside to outside. According to the standardized unit fabricated composite wall, materials with the characteristics of
thermal insulation, fireproofness, dampproofness, sound insulation, attractiveness and the like are made to be a unit fabricated composite wallboard, the wind resistance performance, the airtight performance, the watertight performance and the in-plane deformation performance of a wall surface
system are guaranteed, standardized
prefabrication, unit-type forming,
integrated transportation and fabricated installation are further achieved, and the standardized unit fabricated composite wall can be applied to wall systems in the field of steel structure houses.
