かかり、いずれも施工性が悪いという問題があった。However, it takes a lot of time and labor to embed an insert fitting (not shown) in the ceiling slab surface (1), attach a large number of suspension members (2) and hang it down. As illustrated in, the long field material (5) is connected to the short field material (5a) through the connecting material (6).
When forming a double-ceiling structure with different levels by suspending and supporting the different levels, the portion where the long field material (5) and the short field material (5a) are overlapped is the space above the ceiling. Becomes narrower,
Since it becomes an obstacle when arranging a duct, a ceiling-embedded air conditioner, etc. in the space above the ceiling, the long field material (5) is cut and removed at the overlapping portion, and the hanging material (2) is removed. Since it is necessary to change the position, it takes more time and labor, and there is a problem that workability is poor.
