<p>PROBLEM TO BE SOLVED: To provide a filling property inspection method in concrete placing, which enables it to be rapidly determined whether or not a bottom steel plate surface of a composite floor slab can be filled with concrete and which has recordability.SOLUTION: In placing of concrete 22 on a composite floor slab 12 with a bottom steel plate 14, information on an excitation position is recorded in the same medium (voice recording device 40) by a voice in the same audible range as that of an inspection sound, when filling properties are inspected by using a hammering sound in the audible range generated by hitting the bottom steel plate 14, for example, with a hammer 50 with a trigger or the inspection sound in the audible range generated by performing excitation by an oscillator (hitting ball 54).</p> |
