PURPOSE: A hollow slab unit with enhanced convenience of construction and a method of constructing a slab using the same are provided to construct a high quality hollow slab by omitting part of a main bar required for weakening buoyancy due to concrete placing and for constructing the slab. CONSTITUTION: A hollow slab unit(100) with enhanced convenience of construction comprises a cage, and a light ball(B). The cage provides a space to hold the light ball and forms the outer frame of the hollow slab unit. The cage comprises a plurality of guides(110) and a connecting unit(120). The guides are arranged at regular intervals and comprise a pair of unit guides. The connecting unit connects the guides. The light ball is inserted into the cage and forms a slab. The light ball is coupled to be able to make movements relative to the unit guide to weaken buoyancy due to concrete placing to construct the slab. |
