The present invention relates to a one touch separating type device for preventing buoyance in a hollow core slab to prevent a lightweight molding material to be widely used for a wooden mold from coming off; and to enable an unskilled worker to easily install or separate a device for preventing the buoyance of a lightweight molding material on or from a hollow core slab using a one touch method, although installation and separation for an existing device for preventing the buoyance of a lightweight molding material are complex, inconvenient, and dangerous for the workers. |
