The invention relates to the technical field of construction, and inparticular relates to a dry-method construction method for a high-performance autolaved aerated concrete block wall. The dry-method construction method comprises the following process procedures: performing construction preparation, positioning and paying off, leveling a wall foundation, erecting story poles, placing wall tie bars, constructing a block wall body, laying pipelines inside the wall body, mounting door/window hole cross beams, constructing outer wall concrete thermal bridge parts, constructing an outer wall waterproof interface agent, pasting special plaster putty on the inner wall in batch, constructing an inner wall finish coat layer, pasting wall surface heat-preservation blocks, and constructing a roof surface finish coat layer. The dry-method construction method is characterized in that a dry-method construction process is adopted for a blocking wall body, the part between the wall body and a beam top is filled with a polyurethane foamed adhesive, moreover a special construction method of an outer wall concrete thermal bridge part is adopted, the common quality problems of creep change of conventional masonry mortar and mortar joint cracks along wall surfaces are effectively solved, the overall property, the shock resistance and the heat-preservation property of the wall are improved, and the dry-method construction method can be widely applied to production construction of various buildings.
