Anti-cracking structure of high-rise building

The utility model belongs to the field of constructional engineering, and particularly discloses a high-rise building anti-cracking structure which comprises a steel framework mesh plate layer, a concrete pouring layer, a heat preservation plate layer, an anti-cracking mortar layer, a reinforced composite mesh layer and a decoration panel layer which are sequentially arranged from left to right. The concrete pouring layer, the heat preservation plate layer, the anti-crack mortar layer and the reinforcing composite net layer are sequentially connected in an attached mode to form an anti-crack composite layer, the anti-crack composite layer and the decoration panel layer are bonded through pouring adhesive to form a bonding layer, and a plurality of reinforcing ribs penetrating through the anti-crack composite layer are arranged on the steel framework net plate layer in a rectangular array mode. A plurality of positioning blocks embedded into the anti-crack composite layer are arranged on the decoration panel l
