Anti-crack ground thermal insulation composite structure

The utility model belongs to the technical field of building structures, and discloses an anti-crack ground heat preservation composite structure. The anti-crack ground heat preservation composite structure comprises a concrete ground, and a heat preservation layer, a grid anti-crack layer and a gypsum self-leveling layer which are laid on the concrete ground in a laminated manner, wherein the heat preservation layer is divided by the gypsum partition blocks in a matrix mode, and the grid anti-crack layer is located in the gypsum self-leveling layer so as to horizontally divide the gypsum self-leveling layer into an upper layer and a lower layer. According to the anti-crack ground heat preservation composite structure, the gypsum partition blocks and the grid anti-crack layer are additionally arranged, a common construction method of an existing anti-crack ground heat preservation structure is matched, and the problems that the existing anti-crack ground heat preservation structure is prone to hollowing and c
