The present invention relates to an anchor to prevent a void former from floating in a void slab which has a wire with a bottom end connected to a mold for the void slab and a top end connected to a latticed steel bar on the void former, which fixates the steel bar pressing the void former not to float during concrete casting. According to the present invention, the anchor to prevent the void former from floating in the void slab includes a hemispherical under-head unit (11) on the bottom end of the wire (10), and a cylindrical member (20) having an upper-head unit (22) inserted into the wire (10) wherein the bottom end of the cylindrical member (20) is in contact with the under-head unit (11); three cut portions (24) formed in a longitudinal direction on the cylindrical member (20); and three split pieces (26) formed on the cylindrical member (20) by the cut portions (24). If the wire (10) is pulled upwards by a coupling gun (40) while the upper-head unit (22) is caught around a hole (31) of the mold (30), the three split pieces (26) on the cylindrical member (20) are bent into a ″⊂″ shape by the under-head unit (11) formed on the bottom end of the wire (10) such that the upper-head unit (22) is pressed on the top surface of the mold (30); the three bent split pieces (26) are pressed on the bottom surface of the mold (30); and concurrently, the top end of the wire (10) is caught on an upper main bar (35) installed in the mold (30). |
