PROBLEM TO BE SOLVED: To simplify construction work for a ceiling with a ceiling finishing material formed of a rock wool sound absorbing plate, and recover the rock wool sound absorbing plate when dismantling a building. SOLUTION: A substrate such as a gypsum board is omitted by directly adhering a peripheral edge portion of the rock wool sound absorbing plate 4 to a light gauge steel substrate 1, and fixing it thereto by a tacker 5. In constructing the ceiling formed of the rock wool sound absorbing plate 4, the light gauge steel substrate 1 is assembled, a quick drying adhesive 6 is applied to the surface thereof, the peripheral edge portion of the rock wool sound absorbing plate 4 is adhered to the light gauge steel substrate 1, and temporarily fixed thereto. The rock wool sound absorbing plates 4 fitted adjacent to each other are joined, and the peripheral edge portion of each rock wool sound absorbing plate 4 is fixed to the light gauge steel substrate 1 by the tacker 5. |
