Abstract

PROBLEM TO BE SOLVED: To improve the waterproof property and facilitate the execution work by providing ceiling cornice bodies in which ceiling cornices are held through a cut-off member at the gap between a wall face panel and a ceiling panel, a recessed groove in which the ceiling panel is fitted, and a fixing part fixed to the wall frame. SOLUTION: The side end of a ceiling panel 2 is fitted and connected to the recessed groove 6 of a ceiling cornice 3, and the underface of the ceiling panel 2 and the ceiling cornice 3 are water-tightly fixed. The indoor side- engaging piece 8 and the outdoor side-engaging piece 9 in the fixing part 7 are fixed so as to hold the upper end of the wall face panel 1, and a folded piece 22 is positioned to contact the side face of the wall frame 10. And hence, the ceiling cornice 3 is fixed to the wall face panel 1 so as not to be pushed up and dislocated, and the underface of the ceiling cornice body 5 and the upper end of the wall face panel 1 are connected water-tightly. Accordingly, the ceiling panel and the wall face panel can be connected water-tightly and the face side of the ceiling cornice from the indoor side can be reduced and the execution work can be simplified.
