Thermal insulation wall structure

The utility model is suitable for the technical field of building construction, and provides a thermal insulation wall structure which comprises an outer wall, an inner wall and a thermal insulation layer which are sequentially arranged. A hollow interlayer is arranged between the outer-layer wall body and the inner-layer wall body, and the hollow interlayer is filled with a heat insulation material; when the heat preservation wall body structure is installed, the outer layer wall body is located outdoors, and the inner layer wall body and the heat preservation layer are located indoors. The thermal insulation layer is mainly used for indoor thermal insulation; the outer-layer wall body and the inner-layer wall body are separated through the hollow interlayer, the hollow interlayer is filled with the heat insulation material, and the heat insulation material serves as a buffer layer, so that heat exchange between the outer-layer wall body and the inner-layer wall body is reduced, and the situation that when t
