According to the first aspect of the present invention, the panel fixing metal is guided by the rail while the fitting portion is fitted into the rail formed in the longitudinal direction of the beam main body. Since it is slidably attached to the beam, the panel fixing bracket can be freely moved to an optimum position according to the situation at the construction site, and the ceiling panel can be fixed to the panel fixing bracket at that position. Therefore, when installing the ceiling panel, many panel supporting brackets are attached to the beam by screwing, and then the ceiling panel is fixed to the bracket. Therefore, it is not necessary to perform a difficult operation at a site where a screw hole is screwed, and it is possible to achieve a great efficiency of the site construction.

Further, since the panel supporting member is slidably mounted on the rail portion of the beam main body in advance, extra parts such as screws and bolts for mounting the panel supporting member to the beam member and further wedge members. Is not required, the number of parts is reduced accordingly, and the manufacturing cost can be reduced.

According to the second aspect of the present invention, one of the rail portion and the fitting portion has a center angle of 180 in a sectional view.
A guide groove extending in the longitudinal direction having an arc shape larger than ° is provided, and a cylindrical body which is fitted in the guide groove so as to be relatively movable in the longitudinal direction in a retaining state is provided on the other side. In the state where the panel fixing bracket is fixed to the ceiling panel, it is possible to rotate the panel fixing bracket around the groove center of the guide groove in a state where the panel fixing bracket is prevented from coming off from the rail portion. It is possible to cope with variations in the thickness dimension.

According to the third aspect of the present invention, since the direction of the opening of the guide groove is set so that the metal fitting body is folded upward, the metal fitting body of the panel fixing metal fitting is used before the beam member is used. By folding and fixing to the beam main body with an adhesive tape or the like, the panel main body does not become an obstacle, and the storage cost and the transportation cost can be reduced. Further, at the time of use, by releasing the folded state by the adhesive tape or the like, the panel fixing metal can be used immediately.

According to the fourth aspect of the present invention, since the seal member mounting groove for fitting the seal member over the entire length in the longitudinal direction is provided on the upper surface side of the receiving plate, the belt-shaped seal member having a thickness dimension larger than the groove depth. The ceiling panel is supported by the receiving plate by being fitted in the sealing member mounting groove, so that the lower surface of the edge of the ceiling panel abuts on the sealing member, whereby the connection position between the beam member and the ceiling panel is A reliable sealing effect can be obtained.

According to the fifth aspect of the present invention, the connecting portion has a U-shaped U-shape in a cross-sectional view over the entire length in the longitudinal direction of the beam main body, and is directed from the upper edge of the U-shape to a direction facing each other. The projecting protruding beam body has a retaining strip extending over the entire length in the longitudinal direction. Therefore, the tip of the suspension member is formed as a rod-shaped body having a diameter slightly smaller than the gap between the retaining strips. For example, by screwing a nut having an outer diameter slightly smaller than the groove width of the U-shape to the body, the nut inserted into the U-shape by externally fitting the gap between the retaining strips to the rod-like body. It is blocked by the retaining strip and is prevented from falling downward, so that the beam member can be suspended by the suspension member.

In this state, the bar can move relatively in the longitudinal direction in the gap between the retaining strips, so that the beam can be easily positioned by this movement. Therefore, in the method in which the bracket is screwed to the beam and the beam is connected to the suspension member via the bracket, the screwing operation of the bracket is troublesome, and it is difficult to position the beam freely. Can be solved.
