Prefabricated gable wall capable of being circularly used and connecting structure thereof

The invention discloses a prefabricated gable wall capable of being circularly used. The prefabricated gable wall comprises a heat preservation layer, concrete layers and auxiliary stress structures,the concrete layers are mounted on the two sides of the heat preservation layer, the concrete layers are attached to the heat preservation layer to reinforce the physical property of the heat preservation layer, the auxiliary stress structures are mounted in the concrete layers to improve the physical property of the concrete layers, the auxiliary stress structures comprise anchorage steel reinforcing ribs mounted in the concrete layers and embedded columns embedded in the concrete layers, the heat preservation layer and the concrete layers form a gable wall body, and a hidden beam is mountedabove the gable wall body. The gable wall is simple in structure, during use, connection between the gable wall and a floor is convenient, due to the fact that the hidden beam is in abut joint with the floor directly, position
