This is solved by an optical ceiling system comprising a ceiling mounting frame for mounting.
[0005]
Individual panel members, panel material couplers, structural members of the ceiling mounting frame, etc. are packed and stored in a disassembled state, and are transported to the work site and assembled on the spot. The panel member is bent at an arbitrary bending angle along the longitudinal direction at the center in the width direction. When a plurality of panel members are arranged in parallel so that the bent portions are on the same plane, both side edges of the panel members are on the same plane.
[0006]
Adjacent side edges are fitted into the two connecting grooves of the panel member connector to connect the panel members. Thus, the panel main body obtained by connecting the panel members via the panel member connector is supported on, for example, a ceiling mounting frame having the outer peripheral shape of the panel main body, and is attached to the ceiling. The assembly procedure is arbitrary. For example, both ends of the panel member connector are fixed to the ceiling mounting frame in advance with bolts or the like, and then the side edges of each panel member are connected to the connection grooves of the panel member connector. It can also be assembled by sequentially fitting.
[0007]
Further, in the present invention has a shape corresponding to the cross-sectional shape of the panel body which is obtained by connecting each panel member by having a panel body supporting member for supporting the panel body at both ends, in addition to the There are the following effects.

Preferably, after arranging the panel main body supporting member along the inner wall surface of the ceiling mounting frame in advance, the panel main body is directly or assembled to integrate the three.
[0009]
As described above, when the panel main body is supported by the panel main body supporting member, the form of the panel main body obtained by connecting with the panel member connector is stabilized, and the form is not easily broken even by, for example, an earthquake. Further, when the panel body is closely supported by the panel body support member, when the panel body having a bent shape is assembled to the ceiling mounting frame, there is a gap between the ceiling mounting frame and the panel body by the panel body support member. However, the illumination light does not leak from the gap, and the contrast between the ceiling and the lighting fixture becomes clear.
[0010]
The invention according to claim 2 is a connector for a plurality of long panel members applied to the optical ceiling system according to claim 1, and has a length substantially the same as that of the panel member, and is long. Two connecting grooves having a reverse V-shape that are parallel to each other and intersect at the same angle as the V-shaped angle of the panel member are formed. Since this panel member connector can connect adjacent panel members along the longitudinal direction, the strength and rigidity of the connection portion can be increased, and the center portion of the panel member in the longitudinal direction can be increased by the weight of the panel body. Is prevented from being deformed.
[0011]
The invention according to claim 3 is characterized in that the two connecting grooves are arranged such that each cross section is spaced apart from each other with an intersection angle of 0 ° to 180 °. Due to the arrangement of the connecting grooves, the panel members can be connected at a connecting portion of adjacent panel members with a bending angle that matches, for example, the bending angle of the panel member itself.
[0012]
The invention according to claim 4 is the panel member connector according to claim 2 or 3 , wherein at least both ends have hollow portions. This hollow portion can also be formed over the entire length of the connector. When forming the hollow portion over the entire length of the connector, the connector can be made thicker and rigid even with the same amount of material, and if the hollow portions at both ends are screw holes, This is preferable because it can be fixed to a flat plate-shaped deflection preventing member attached to both ends to stabilize the end form of the panel body using bolts or the like.
