PURPOSE:To simplify installation work by providing groove parts at end members on both sides of a wooden bed panel of ceiling, and by fixing one of the end members to a ceiling joist by engaging the grooves of the neighboring panels with each other. CONSTITUTION:A wooden bed panel 1 of a ceiling is formed by assembling plural long size wooden members 2 and plural short size wooden members 3 like a lattice work. Grooved parts 4 are carved in end materials 3a and 3b at both ends of this panel 1. Then, one of the end material 3a is fixed to a ceiling joist 6 by means of nails 5. Then, the end material 3a is fixed by engaging the end material 3b of the neighboring bed panel 1 with the groove 4 of the end material 3a of the bed panel 1 fixed to the ceiling joist 6. Thus, it is possible to simplify the installation work by connecting the panels easily. |
