Detailed Description

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, a schematic structural diagram of a cavity floor slab in the embodiment of the present invention includes a bottom plate 1 and a face plate 2, the bottom plate 1 is provided with bottom ribs 4, the face plate 2 is provided with gluten 5, wherein the face plate 2 is provided with an opening groove 3, at least two heat insulation layers 6 are arranged between the bottom plate 1 and the face plate 2, and the heat insulation layers 6 are uniformly arranged at equal intervals. The heat insulation layer 6 blocks a heat bridge and can play a role in heat insulation. The thickness of the heat insulating layer 6 is 1/3 of the whole plate thickness.

Thermal insulation mortar is filled between the thermal insulation layers 6. According to the difference of the internal stress condition of the floor slab, the heat preservation and insulation layer 6 is arranged at the position with small bending resistance and shearing resistance so as to improve the heat preservation and sound insulation performance of the floor slab, heat preservation and insulation mortar is filled at the stress concentration position, and the heat preservation and insulation mortar generally has good heat preservation and sound insulation effect and structural strength at the same time, so that the heat preservation and insulation mortar is arranged to play a role in supporting.
