Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling panel mounting structure, and more specifically, to a ceiling in a grid portion formed by a ceiling bar suspended via suspension bolts suspended from a ceiling slab. The present invention relates to a ceiling panel mounting structure for installing panels.

[0002]

2. Description of the Related Art Generally, a ceiling bar of a system type in which ceiling bars suspended by a suspending metal fitting attached to suspension bolts suspended from a ceiling slab are connected in a grid pattern and ceiling panels are arranged in the grid portion. A panel mounting structure is known (Japanese Utility Model Laid-Open No. 61-201410, JP-A-3-14).
7959 gazette). In this type of ceiling panel mounting structure, the ceiling bars are connected to each other by connecting metal fittings to form a grid section, and one ceiling panel is arranged in the grid section, or the ceiling bars facing each other in the grid section are arranged. It has a structure in which a plurality of ceiling panels whose both ends are installed between the bars are arranged.

Further, as a structure for joining ceiling panels,
A structure is known in which a fixture is fitted to the upper protruding portion of a ceiling bar having ceiling panels placed on both sides, and the ceiling panel is held between the fixture and the panel placement surface of the ceiling bar ( See Japanese Utility Model Publication No. 3-117024).

[0004]

However, in the structure in which one ceiling panel is arranged in the grid portion,
Since the ceiling panel is arranged in each grid portion, there are problems that the number of constituent members increases, the structure becomes complicated, and the construction is troublesome. On the other hand, in the structure in which a plurality of ceiling panels are arranged in the grid part, the number of constituent members can be reduced, but the grid part needs to have rigidity, and the ceiling bar itself must be robust. It is necessary to increase the wall thickness of the ceiling bar,
There is a problem that it is necessary to select a material having high strength, and moreover, the weight of the ceiling portion itself increases. Further, there is a problem that the shape of the grid portion and the shape of the ceiling panel cannot be matched with the rectangular shape, and the appearance of the ceiling surface is impaired.

Further, in the conventional ceiling panel joining structure, since the fixing tool has to be fitted to the ceiling bar after the ceiling panel is placed on the ceiling bar, the construction is troublesome and the fixing tool is mounted on the ceiling bar. Since it was necessary to prepare it separately from the bar, the number of constituent members increased, and inventory management was troublesome.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a ceiling panel mounting structure capable of reducing the number of constituent members, improving workability, and improving the appearance of the ceiling finished surface. It is intended.

[0007]

In order to achieve the above object, in the ceiling panel mounting structure of the present invention, a grid portion is formed by a ceiling bar that is suspended via suspension bolts that are suspended from a ceiling slab. In a ceiling panel mounting structure in which a ceiling panel is installed in the grid section, one end of the ceiling panel is engaged with a ceiling bar on one side of the grid section, and the other end of the ceiling panel is connected to the grid section. It engages with the panel locking bar installed between the opposing ceiling bars.

In the present invention, a locking strip for engaging the ceiling panel is provided on the ceiling bar, and the panel locking bar is formed by a member having a substantially C-shaped cross section which opens downward, and from the edge of the opening. The locking panel is formed so as to stand upward, and the ceiling panel has an outward locking hanging piece that engages with the locking bar of the ceiling bar at one end and the panel at the other end. It is preferable to form an inward locking hanging piece that engages with the locking ridge of the locking bar.

Further, in order to ensure the engagement between the panel locking bar and the ceiling panel, the panel is dropped into the panel locking bar by constantly urging the elastic force toward the opening side of the panel locking bar. It is preferable to interpose a prevention spring.

[0010]

According to the ceiling panel mounting structure of the present invention constructed as described above, one end of the ceiling panel is engaged with the ceiling bar on one side of the grid portion, and the other end of the ceiling panel is attached to the grid portion. By engaging the panel locking bars that are installed between the facing ceiling bars, it is possible to easily install a plurality of ceiling panels in the grid portion with a small number of constituent members.

An outward locking hanging piece provided at one end of the ceiling panel is engaged with a locking strip provided at the ceiling bar, and an inward locking hanging piece provided at the other end of the ceiling panel. By engaging with the locking ridge provided on the panel locking bar, the gap between the adjacent ceiling panels can be made as small as possible.

Further, by interposing a panel fall prevention spring in the panel locking bar which constantly applies elastic force toward the opening side of the panel locking bar, the inward locking hanging piece of the ceiling panel is panelized. When engaging with the locking ridge of the locking bar,
Since the push-up is engaged against the elastic force of the panel drop prevention spring so as to be engaged, the installation of the ceiling panel can be further ensured. Moreover, it is not necessary to separately prepare a panel drop prevention spring, and the ceiling panel can be easily engaged with the panel locking bar.
