もあった。However, in the conventional connection structure of the ceiling material 3, the metal outer cover 11 on the upper side of the ceiling material 3 and the ceiling material support hardware 31 are fixed by a fixture 31 '.
Further, it is necessary to fix the ceiling material supporting hardware 31 and the suspension bolts 2, and furthermore, the connection of the end 3 a of the ceiling material 3 (the end where the male and female members are not provided) is performed by the ceiling material supporting metal 31 or the like. Since this is performed using the joint fitting 4 ′, which is a separate component from the hanging bolt 2, the number of ceiling components increases, and there is a problem in that the installation of the ceiling material 3 takes time. In addition, since the joint fitting 4 'is not directly supported by the suspension bolts 2, the worker cannot walk directly on the ceiling material 3 during construction or maintenance of the ceiling material 3 without worrying about a separate catwalk. Become. Furthermore, when mounting a lighting device or the like on the ceiling material 3, conventionally, since the lighting device frame is directly mounted on the lower surface of the ceiling material 3, not only is it difficult to adjust the dimensions when mounting the lighting device frame, When fixing the lighting fixture frame with screws, it is necessary to drive the screw into the ceiling material 3 with a screwdriver while supporting the lighting fixture frame by hand, and it is necessary to separately perform wiring for lighting. The work requires much labor and time, and furthermore, there is a problem that the appearance of the ceiling is impaired due to the exposure of the lighting fixture frame to the lower surface of the ceiling material 3.

のである。As described above, according to the first aspect of the present invention, the joint fitting for connecting the ends of the ceiling material to the lower end of the suspension bolt fixed to the base of the ceiling is provided. Are mounted integrally, and a U-shaped ceiling material insertion part is provided on both sides of the joint bracket, each opening to the side. Between the ceiling material insertion parts, various functions such as lighting fixtures, curtain rails, partition rails, etc. Since an inverted U-shaped mounting recess is provided at the lower side where the member can be mounted, the ceiling material is connected and supported by inserting the end of the ceiling material into a joint fitting integrally attached to the suspension bolt. Can be easily and firmly connected by using a joint fitting, so that the metal shell on the upper side of the ceiling material and the ceiling material support metal are fixed with a fixture, and the ceiling material is further fixed. Eliminating the need or fix the bolt hanging and lifting hardware, thereby facilitating construction is. In addition, since the joint fitting is integrally mounted with the suspension bolt, the number of parts used is small, and the simplification of the ceiling component material can shorten the construction period and reduce the cost. Is directly supported by the ceiling base, allowing workers to walk directly on the ceiling material without the need for a separate catwalk during construction and maintenance of the ceiling material. And the construction and maintenance of the ceiling material can be performed easily. Further, by mounting various functional members such as lighting fixtures, curtain rails, partition rails, etc. in the joint mounting recesses, there is no need to adjust the dimensions of the mounting positions of the functional members, so that the functional members can be positioned with good appearance and accurate position. It is possible to mount the ceiling with high accuracy, and it is possible to further enhance the design of the ceiling.
