[0122] The present invention is also characterized in that the top plate 3 of the lightweight carcass 2 has an upper plate 32 of cast-in-place reinforced concrete, and the lower part of the lower bottom 5 has a lower plate 33 of cast-in-place reinforced concrete. Fig. 1 is the structural representation of embodiment 1 of the present invention, and the top plate 3 of lightweight carcass 2 has cast-in-place reinforced concrete upper plate 32, and the bottom of lower bottom 5 has cast-in-situ reinforced concrete lower plate 33.
[0123] The present invention is also characterized in that the top plate 3 of the lightweight carcass 2 has no cast-in-place reinforcement upper plate 32, and the upper surface of the top plate 3 is flush with the upper surface of the cast-in-place concrete hollow plate. Fig. 35 is a schematic structural view of Embodiment 35 of the present invention. The top plate 3 of the lightweight carcass 2 has no cast-in-place reinforcement upper plate 32, and the upper surface of the top plate 3 is flush with the upper surface of the cast-in-place concrete hollow plate.
[0124] The present invention is also characterized in that the lower part of the lightweight carcass 2 does not have a cast-in-place reinforced concrete lower plate 33, and the lower surface of the lightweight carcass 2 is flush with the lower surface of the cast-in-place concrete hollow slab. Fig. 34 is a schematic structural view of Embodiment 34 of the present invention. The lower part of the lightweight carcass 2 does not have a cast-in-place reinforced concrete lower plate 33, and the lower surface of the lower bottom 5 is flush with the lower surface of the cast-in-place concrete hollow plate.
[0125] The present invention is also characterized in that the top plate 3 of the lightweight carcass 2 has no cast-in-place reinforcement upper plate 32, the upper surface of the top plate 3 is flush with the upper surface of the cast-in-place concrete hollow plate, and the lower part of the lightweight carcass 2 has no Cast-in-situ reinforced concrete lower plate 33. Figure 36 is a schematic structural view of Embodiment 36 of the present invention, the top plate 3 of the lightweight carcass 2 has no cast-in-place reinforcement upper plate 32, the upper surface of the top plate 3 is flush with the upper surface of the cast-in-place concrete hollow slab, and the lightweight carcass 2 There is no cast-in-place reinforced concrete lower slab 33 in the bottom of the bottom 5, and the lower surface of the lower bottom 5 is flush with the lower surface of the cast-in-situ concrete hollow slab.
[0126] The present invention is also characterized in that the said cast-in-place concrete hollow slab contains prestressed tendons 28 . Fig. 37 is a schematic structural view of embodiment 37 of the present invention, in which the cast-in-place concrete hollow slab contains prestressed tendons 28 .
[0127] The present invention is also characterized in that the cast-in-place concrete hollow slab contains steel frames 29 . Fig. 38 is a schematic structural view of embodiment 38 of the present invention, in which the cast-in-place concrete hollow slab contains steel frames 29 .
[0128]The present invention is also characterized in that hidden beams 30 and exposed beams 31 are also arranged in the cast-in-situ concrete hollow slab. As shown in Fig. 37 and Fig. 38, hidden beams 30 are also arranged in the cast-in-place concrete hollow slabs, and Fig. 39 is a schematic structural diagram of embodiment 39 of the present invention, and exposed beams 31 are also arranged in the cast-in-place concrete hollow slabs.
[0129] During the implementation of the present invention, first install the support or formwork according to the construction requirements, lay the lightweight carcass 2, then lay the steel bars or the steel bars of the hidden beams 30 or the exposed beams 31, and various pipeline embedded parts, and pour concrete after acceptance. After the concrete is solidified and hardened, it is cured to the specified age, and the formwork is removed to obtain the cast-in-place reinforced concrete slab.
