Embodiment Construction
[0023] Such as figure 1 As shown, the schematic diagram of the cast-in-place hollow floor and the thin-walled box inside, the floor 1 includes the thin-walled box 2 in the middle, the upper flange plate 3, the rib beam 6, the lower flange plate 4, and the thin-walled box 2 There are multiple and cast-in-place with composite cement slurry or assembled by plates. The bottom plate of the thin-walled box body 2 has arc-shaped protrusions 8 whose height is ≤19mm, 100mm≤arc-shaped length≤300mm, and the arc-shaped protrusions on the bottom plate There are at least three arcs from 8, and the priority is to maintain balance. The bottom plate and the top cover have opposite lower holes and upper holes, and the lower holes on the bottom plate are connected with the upper holes on the top cover through a closed through passage 5, 50mm≤straight diameter or side length≤180mm. The air suction port 10 of this scheme directly passes through the lower flange plate of the floor and the thin-wal...
