High-rise building underground non-heating area composite beam plate heat preservation system

The utility model discloses a combined type beam plate heat preservation system for an underground non-heating area of a high-rise building, and belongs to the technical field of building energy-saving construction. Which comprises a spraying heat preservation layer (10) and is characterized in that the spraying heat preservation layer (10) covers the surface of the horizontal plane of a board bottom (1), beam heat preservation layers (7) are arranged on the side face and the bottom face of a downwards-protruding beam (6) on the surface of the board bottom (1), and each beam heat preservation layer (7) comprises a polymerized polystyrene board layer (18) connected with the spraying heat preservation layer (10). In the composite beam-slab thermal insulation system for the underground non-heating area of the high-rise building, the construction technology of combining thermal insulation layer spraying and polymerized polystyrene board pasting is adopted, and the inorganic fiber spraying technology is adopted fo
