Abstract
The utility model discloses a thin-walled box used in a cast-in-place concrete hollow roof. The thin-walled box is a hollow structure, comprising a top plate (1), a bottom plate (2) and a side wall (3). A locating flange rib (4) is installed on the external surface of the side wall (3). Flange ribs at the thin-walled box make the position of the thin-walled box accurate and firm and ensure the thickness of the reinforcement cover of a ribbed beam. The peripheral concrete solid part accords with the design requirements. The installation of a raiser block 5 guarantees the gap between the bottom of the thin-walled box and a moulding board. The cast concrete is easy to enter into the gap, which is beneficial for the concrete entering below the thin-walled box to fully wrap the thin-walled box. Thus, the bottom of the concrete plate is fully filled with the concrete. Hollowness and honeycomb at the bottom of the roof are avoided. The construction quality of the cast-in-place concrete hollow roof is guaranteed.
