PURPOSE:To improve sound insulation and airtightness by combining a frame assembled in a rectangular outline with a pair of right and left long flat boards and a par of front and back short flat boards to be core material and a ceiling panel with plaster boards adhered to both faces and extending it between walls. CONSTITUTION:A ceiling panel 1 is mainly constituted of a frame 2 assembled in a rectangle with a pair of right and left long flat boards 2a to be core mate rial and a pair of front and back short flat boards 2b to be core material, plater boards 3, 4 adhered to both faces of the frame 2 and a heat insulating material 5 filled between ring bodies. One end of the long flat board 2a is made protrude from an end of the plater boards 3, 4 while the other end is drawn inside the end so that adjacent boards can be nested alternately. Numer ous through holes 3a communicating inside and outside are formed on one of the plaster boards 3, and while a lengthwise end of the ceiling panel 1 is fitted in, the panel is extended via hanging beams over a ceiling. Thus a ceiling panel with good application efficiency can be obtained. |
