Abstract

The present invention relates to an assembly for finishing a ceiling with a sound absorption performance. To this end, according to the present invention, the assembly for finishing a ceiling with sound absorption performance comprises: a ceiling frame with a plurality of insert holes; carrying bars engaged with each insert hole formed on the ceiling frame to be placed on the ceiling frame in a grid structure; a hanger member connected to a hanger bolt fixed on a ceiling slab, and simultaneously supporting the pair of carrying bars by traction; and a ceiling panel attached to the lower surface of the ceiling frame. The ceiling frame has continuous indented units on three surfaces, except an upper surface where a recess groove is formed to increase rigidity, and thus, the curved cross-sectional variation offsets a noise frequency by irregular diffused reflection. In addition, a plurality of penetrating holes distributing the noise frequency are formed on three surfaces, except a lower surface to which the ceiling panel is attached, thereby converting the noise frequency into heat by a fierce friction at an entrance of the penetrating holes so as to primarily reduce noise. The ceiling frame and the ceiling panel minimize a contact area by the indented units and form an air layer to minimize the transfer of impact and noise, thereby secondarily reducing the noise. In the hanger member, a pair of hanger wings, which fix the carrying bars by insertion, are branched with a hanger body in between, thereby keeping the interval between the carrying bars uniform.
