The existing stage ultra-low energy consumption building still adopts the traditional external heat preservation form, however, the external heat preservation method has very serious potential safety hazard in the practical application engineering, on one hand, the problems of cracking and falling of the heat preservation layer easily occur, on the other hand, the external heat preservation is not matched with the service life of the building main body, and the external heat preservation and the building main body need to be replaced in the service cycle of the building. The problem is solved by applying a novel sandwich heat-insulating product to the ultra-low energy consumption building, and the outer side of the sandwich heat-insulating product is provided with a reinforced concrete structural layer with certain thickness, so that the self weight is large, and the cornice is required to be arranged at the floor from the aspect of structural safety, however, the setting of the cornice can generate a heat bridge effect, and the overall energy-saving effect of the ultra-low energy consumption building is reduced. In view of the above, it is desirable to provide a bridge-cut cornice structure capable of avoiding the thermal bridge effect.
