PURPOSE: A one-touch type buoyancy preventing apparatus for a hollow slab is provided to be applied to all wood molds or deck plates and to prevent leakage of water or concrete with a simple structure. CONSTITUTION: A one-touch type buoyancy preventing apparatus (A) for a hollow slab comprises a main body (100), an elastomer (400), a ring (300), and an anchor (200). The main body has a binding unit (101), an elastomer fixing unit (102), and an anchor coupling unit (103). The elastomer is installed by penetrating the lower part of the main body, and the top of the elastomer hangs on the elastomer fixing unit. The ring is installed by penetrating the lower part of the main body and is placed in the lower part of the elastomer fixing unit. The ring prevents leakage of water or concrete by sealing the hole of a mold. The anchor is installed on the lower part of the ring to be coupled to the anchor coupling unit and has an expanding unit (201) which hangs on the lower part of the mold. |
