Abstract

The invention discloses an anti-floating device for fixing reinforcing steel bars and hollow floor slabs. The anti-floating device comprises a base for supporting the reinforcing steel bars, wherein the upper end of the base is provided with iron wires for binding the reinforcing steel bars; a hollow bent pipe through which the iron wires can pass is internally embedded in the base; and openings at two ends of the bent pipe are level to the bottom surface of the base. The anti-floating device can be used for fixing the reinforcing steel bars, so that the reinforcing steel bars are prevented from displacement in the construction process, therefore the thickness of a concrete protective layer prescribed by construction specifications is realized, and the anti-floating effect required for fixing core moulds can also be achieved. After templates are removed, no iron wire ends are remained on the bottoms of the floor slabs, so that any future trouble is ensured not to be left, and therefore the problem that future troubles are caused by the residual abundant iron wires of the hollow floor slabs manufactured by other companies at present is solved.
