Therefore, the states of reinforcing bars arranged in the main body can be easily checked, thereby allowing a superior maintenance work. Also, when a hollow slab is constructed, reinforcing bars may be easily arranged and installed in the main body by opening the cover so that a construction work can be conveniently performed, and a construction period may be reduced. |
