Abstract

PURPOSE:To improve the safety of working and workability by attaching apparatuses such as air-conditioning apparatuses and electric apparatuses at a position close to the ground, finishing a ceiling, and moving the ceiling of a large- space structure to the specified height with lifting means, and fixing the ceiling. CONSTITUTION:This method is different from a conventional method, wherein the ceiling of the structure having the large space is constructed by providing scaffolds. Apparatuses, which are provided at the ceiling, and ceiling finishing materials are assembled on a bed frame 5 on a plane, which is slightly smaller than the planar periphery of a structure A. Thus, the apparatuses and the like are attached in the vicinity of the ground. Then, the frame is lifted through suspending members 4 with lifting devices 1 such as chain blocks, which are suspended from the ceiling (b) through wires 2. The suspending members 4 and suspending members 4a of the bed frame 5 are connected. After the apparatuses, which are provided at the specified positions, are connected to a main-body facility in this way, the lifting devices are removed.
