The invention discloses an aerated concrete block masonry composite wall reinforced with embedded reinforcements and borehole core columns, which belongs to the field of masonry structure and is mainly applied to the building structure engineering. The aerated concrete block masonry composite wall comprises block masonry composed of aerated concrete blocks and dedicated mortar, wall core columns vertically arranged in the block masonry and embedded reinforcements horizontally arranged in the block masonry; horizontal steel bars are generally arranged in block hollow grooves arranged along the length direction of a wall body, and the horizontal steel bars and mortar filled in horizontal mortar joints during the wall building form the embedded reinforcements; vertically through holes are drilled on the block masonry, and core column steel bars are vertically arranged in the holes; and the core column steel bars and core column concrete made of concrete poured after the wall building form wall core columns. The aerated concrete block masonry composite wall disclosed by the invention has relatively good popularization and application prospect in the load-bearing walls of multi-layer masonry structures in seismic areas and even non-load-bearing walls taking aerated concrete block masonries as filler walls in various structure systems.
