Building heat preservation structure

A building heat preservation structure comprises an inorganic active heat preservation structure. The building heat preservation structure is characterized in that the surface of the inorganic active heat preservation structure is sequentially provided with a noise preventing structure, a vacuum heat insulation plate, a protection isolation layer and an outer decoration plate from inside to outside, the inorganic active heat preservation structure is distributed on an outer wall in a segment mode, the noise preventing structure is a double-layer sound insulation blanket, the protection isolation plate is a fireproof heat preservation panel, a groove is formed in the protection isolation plate, the outer decoration plate is provided with a protrusion matched with the groove, and the outer decoration plate is a pvc plate. Compared with the prior art, the building heat preservation structure is simple, heat preservation is achieved through the inorganic active heat preservation structure, the heat preservation e
