Prefabricated compound integrated wall board and application thereof

The invention relates to a prefabricated compound integrated wall board and application thereof. Flanges which extend outwards are arranged at the two sides and upper end of the wall board; the prefabricated compound integrated wall board comprises a concrete layer and a heat-preservation layer; the heat-preservation layer is divided into two layers according to the thickness. The prefabricated compound integrated wall board is internally provided with a steel wire net rack and a steel bar welding net rack is formed by welding two layers of steel bar welding nets with stressing or construction effect by a web bar; the heat-preservation layer is clamped between the two layers of steel bar welding nets; reinforcing steel bars are arranged at the end part and a hole of the steel wire net rack. The prefabricated compound integrated wall board integrates decoration, heat preservation and containment; field construction work of an outer decoration layer and the heat-preservation layer can be effectively avoided, and heat bridge problems of beams and columns and phenomena that the area of a wall body is too great and cracks are formed are effectively solved; the prefabricated compound integrated wall board can be combined with an assembling type framework column and a steel structure so as to form an assembling type framework/steel structure-prefabricated wall board integrated structure system.
