PURPOSE:To shorten installation work and enhance and upgrade a finished state by fixing an opening wooden frame which shows the position of a ceiling opening unit of an air conditioner with mounting screwed holes which are designed to fix a ceiling panel of an air conditioner main body. CONSTITUTION:An opening wooden frame 10 which shows the position of a ceiling opening unit of an air conditioner is fixed with a mounting unit which fixes a ceiling panel of an air conditioner main body 1a, which makes it possible for a carpenter to assemble a ceiling frame and a ceiling in that order along the outer periphery of an opening board 10a, thereby installing a ceiling opening when the carpenter assembles the ceiling. Furthermore, since the opening wooden frame 10 is exposed downward from the ceiling surface, there is no chance for the carpenter to forget the installation work of the ceiling opening. The ceiling opening must be constructed at the same time when the ceiling is assembled, which makes it possible to finish the work with higher accuracy. As described above, this construction makes it possible to shorten the time required for the installation work and enhance a finished state as well. |
