Hollow insulation exterior wall plate

The invention relates to a hollow insulation exterior wall plate, and belongs to house structures in the field of buildings. A reinforcement cage is buried in the middle of a wall, and filling materials are arranged in the reinforcement cage. The whole wall plate is formed by pouring in a mold, concrete with the size of 60 mm is poured in the mold at first, then the reinforcement cage is buried in the concrete, and a space with the size of 120 mm is reserved in an outer edge. The reinforcement cage is filled with prefabricated foaming cement, and then is gripped fixedly. A whole wall is finished by secondary pouring. By the hollow insulation exterior wall plate, the dead weight of a building is reduced, indirect costs and loss are reduced, the construction period is shortened, an economic benefit is considerable, and labor time is saved.
