PURPOSE:To facilitate the mounting work of ceiling plates and facilitate the maintenance or additional work in the ceiling by removably coupling and fixing connecting metals with finger hooks on both ends of an auxiliary cradling to guide grooves on both sides of the vertical section of a main cradling. CONSTITUTION:The middle section 31 of a connecting metal 30 is press-fitted to guide grooves 23 and 26 of an auxiliary cradling 20 by utilizing the spring property and hooked on a claw section 21a for the drop stop, and both end sections of the vertical section 21 of the auxiliary cradling 20 are mounted on the flange section 14 of a main cradling 10 respectively. Both end sections 32 and 33 of the connecting metal 30 are press-fitted to guide grooves 13 and 16 of the main cradling 10 by utilizing the spring property. The auxiliary cradling 20 is slid, both ends 32 and 33 of the connecting metal 30 are hooked on notch sections 12a and 15a of the main cradling 10, and the auxiliary cradling 20 is positioned. The step section 41 of a ceiling plate 40 is mounted on the flange section 14 of the main cradling 10, the auxiliary cradling 20 is fitted, its side end section is supported by a flange 24, the ceiling plates 40 and the auxiliary cradlings 20 are assembled in turn between the main cradlings 10 and 10, and the construction of a ceiling is completed. |
