PROBLEM TO BE SOLVED: To rapidly and accurately arrange a ceiling by fixing ceiling plates to cradlings and fixing the upper end of a hanging tool hanging the cradlings to the upper floor in advance before construction works at site and further, bending the hanging tool and hanging the cradling from the floor at the end during the ceiling construction. SOLUTION: One end of a hanging plate 110 is fixed to the rear face of a deck plate 91 to form a hanging lug for inserting the lower end of the hanging plate 110 in a groove of a cradling 125 for fixing the ceiling plates an hanging it. Then, the ceiling plates are fixed to the cradling 125 and protrusions are formed at both sides of the hanging lug. The protrusions are inserted in the groove of the cradling 125 and engaged therewith to hang down the cradling 125. Hear insulation glass wool 130 is laid between the deck plate 91 and a decorative gypsum ceiling board 132. In this time, the board 132 is screwed in the cradling 125 and fixed by a tap bolt 133. In this way, the ceiling construction can be completed by fixing the board 132 and hence, many works such as the clipping work of the hanging plate 110 and the cradling 125 painting of the ceiling, etc., are not required. Hence, cost and time can be spared. |
