昭６２−１９４８１２号公報参照）。For general suspended ceilings, a channel-shaped ceiling base material is suspended from a hanging bolt suspended from a ceiling slab using a support means such as a hanger, and a ceiling finishing material is attached to the ceiling base material using a suspending means such as a clip. A structure in which a ceiling panel is installed between ceiling finishing materials is known. In this case, the ceiling base materials are assembled on the same plane to form a grid section, and the ceiling finishing material is suspended from the lower surface of the ceiling base materials (Tateho, Japanese Utility Model Publication No. 1-1-18015). Furthermore, in the system ceiling constructed in this way, one is known in which ceiling finishing materials are connected in a grid and a ceiling panel is constructed within the grid (see Utility Model Application No. 1988-194812). ).

There is a problem in that the connection work requires a lot of labor and time. In addition, there is the problem that it takes a lot of time and effort to accurately install the ceiling finishing material at the determined position, and it is not enough to simply suspend the ceiling finishing part using a hanging means on the ceiling base material. It was not possible to obtain a ceiling finish with strength. This invention has been made in view of the above circumstances, and has the primary purpose of providing a ceiling base part that can be easily positioned and has surface rigidity. It is an object of the present invention to provide a ceiling structure whose second purpose is to suspend finishing materials and to include a ceiling finishing grid portion having surface rigidity.

Forming the base part, the above main ceiling base material,
A ceiling panel is installed on a ceiling finishing material that is suspended from a sub-ceiling base material using suspension means. In this invention, the above-mentioned ceiling finishing material may be positioned below the ceiling base material as long as it is suspended by the main ceiling base material and the secondary ceiling base material using a hanging means, but it is preferably located below the ceiling base material. The main ceiling finishing material is parallel to the main ceiling base material suspended from the main ceiling base material via the suspension means, and the secondary ceiling finish is parallel to the secondary ceiling base material suspended from the main ceiling base material via the suspension means. It is better to form a grid portion by intersecting the main ceiling finishing material and the secondary ceiling finishing material at right angles and connecting the intersections of the main ceiling finishing material and the secondary ceiling finishing material by a connecting means. Further, the reinforcing ceiling base material may be any material as long as it is connected to the opposing main ceiling base materials of the two sets of ceiling base rows, but preferably two reinforcing ceiling base materials parallel to each other. It is better to install a rectangular frame for installing equipment between the grid parts, and more preferably to position the rectangular frame in the center of the grid part.
