High-precision building block structure capable of preventing wall from cracking

The utility model discloses a high-precision building block structure capable of preventing a wall from cracking, which comprises an aerated concrete block, the front end and the rear end of the aerated concrete block are respectively and fixedly connected with a foaming ceramic plate, and the interiors of the upper end and the lower end of the two sides of the aerated concrete block are respectively provided with a structure convenient for stacking and aligning. According to the high-precision building block structure capable of preventing the wall from cracking, through the arrangement of the center seam and the side seam, when the high-precision building block structure is used, firstly, a tooth-shaped scraper is used for conducting sizing on a building block on the bottom layer, then a new building block is horizontally placed over mortar, and meanwhile whether the center seam and the side seam of the newly-placed building block are aligned with the center seam and the side seam of the built building bloc
