Building heat-insulation and formwork integrated wall structure and construction method thereof

The invention provides a building heat-insulation and formwork integrated wall structure and a construction method thereof. The building heat-insulation and formwork integrated wall structure is composed of a cast-in-place structure body and a heat-insulation formwork integrated component. The cast-in-place structure body comprises a cast shearing wall, cast floors and suspension lugs. The heat-insulation formwork integrated component is installed between the adjacent suspension lugs. The heat-insulation formwork integrated component comprises a prefabricated concrete formwork layer, a heat-insulation board layer and a heat-insulation formwork connecting net. Positioning cushion blocks are arranged between the heat-insulation board layer and the heat-insulation formwork connecting net. According to the building heat-insulation and formwork integrated wall structure and the construction method thereof, the heat-insulation formwork integrated component is used for replacing an original building formwork, and the suspension lugs are combined with the heat-insulation formwork integrated component, so that the emergency capacity of the heat-insulation wall structure is improved, building heat-insulation and formwork integration is achieved in the true sense, the formwork consumption is reduced, and the common defect of cracking and falling of an outer wall heat-insulation system is completely overcome.
