The reattachment can be performed in the reverse order of the above procedure.

Although there is an example in which the support projections 54 on the holding metal fittings 39 of the fixture 37 simply project outwards, there are a portion along the lower wall 47 of the holding metal fittings 39 and a portion along the inclined wall 55. When it has a V-shaped cross section formed from
When removing the ceiling panel 25, the hanging edge 29 of the ceiling panel 25
Serving as a guide means for guiding the support projection 54
Is reinforced to improve the function as a ceiling panel fall prevention means. Further, when the panel abutting edges 56 are formed on both sides of the second vertical wall 49 in the holding metal fitting 39 of the fixture 37, the holding metal fitting 39 is reinforced and the space between the ceiling panels 25, 25 continuously provided is increased. The position can be accurately regulated including the joint gap.

Since the ceiling panel is attached to the bottom wall of the panel supporting horizontal member with the bottom plate edge of the ceiling panel being crimped, the ceiling panel is stably held on the panel supporting horizontal member. D. The mode of mounting the ceiling panel using the mounting portion provided at the center in the depth direction on the mounting side of the ceiling panel is 1
Appropriate when mounting a single ceiling panel to a panel support horizontal member, and mounting between two adjacent ceiling panels with a joint space in the depth direction on the ceiling panel mounting side. The aspect in which the ceiling panels are attached using the sections is suitable when the consecutively installed ceiling panels are attached to the panel supporting horizontal members one after another. When mounting the consecutive ceiling panels one after another, the upper edge of the insert notch of the ceiling panel abuts on both sides of the fixture holding fixture, so the depth of the holding fixture is set to the joint of the consecutive ceiling panels. If the gaps are accommodated, the installation positions between the ceiling panels are automatically regulated at the same time when the ceiling panels are installed, and it is not necessary to measure and set the installation positions of the individual ceiling panels.

E. Even if the bottom panel edge of the ceiling panel falls off from the bottom wall of the panel support horizontal member due to earthquake motion or contact during installation work, the attached ceiling panel can be attached to the fixture holding bracket. Since the supporting protrusions are present in a state that they are included inside the ceiling panel at the side of the insertion cutout of the ceiling panel, the supporting protrusions support the folded back horizontal edge sandwiched between the rising edge and the hanging edge of the ceiling panel on the mounting side. , Prevent the ceiling panel from falling. F. The laid ceiling panels can be individually removed and reattached. In the case of removal, the ceiling panel placed on the panel support horizontal member on the mounting side is lifted against the pressure of the fixture spring parts, and the ceiling panel is lifted to the top wall and the second side wall of the panel support horizontal member. And by using the space surrounded by the intermediate bottom wall, it moves in the horizontal direction to disengage the mounted state of the other side of the ceiling panel and lower it, so that the support protrusion on the mounting side passes through the insertion notch of the ceiling panel. Remove the ceiling panel by moving it so that it separates. Reattachment is performed in the reverse order of the above procedure. G. In the case where panel guide pieces with the depth direction tip sloping upward are provided on both sides of the free side of the hypotenuse part of the fixture spring part in the depth direction, the ceiling panel should be placed on the panel support horizontal member beforehand. Slide the ceiling panel in the length direction of the panel support horizontal member until it moves to the position of the fixture fixedly installed, and then automatically attach the spring end of the spring part of the fixture to the free end. It serves as a guiding means when locating the side on the folded horizontal edge of the ceiling panel.

H. When the fixture fixing screw is screwed onto the second vertical wall of the fixture holding metal fitting, the spring part hanging piece of the fixture attached to the panel support horizontal member and the first metal holding fixture vertical wall are attached. By crimping and fixing to the second side wall of the panel support horizontal member, the fixture can be fixed to the predetermined position where the ceiling panel of the panel support horizontal member is mounted, and the ceiling attached to the fixture can be fixed. With respect to the panel, it is possible to prevent the panel supporting horizontal member from being displaced in the length direction. I. If the support projections on the fixture holding bracket have a V-shaped cross section that is formed by the portion along the lower wall of the holding fixture and the portion along the sloping wall, guide the hanging edge of the ceiling panel when removing the ceiling panel. In addition to serving as a guide means, the support projections are reinforced to improve the function as a ceiling panel fall prevention means. J. When panel abutting edges are formed on both sides of the second vertical wall in the fixture holding metal fitting, the holding metal fitting is reinforced and the position between the consecutive ceiling panels is accurately controlled including the joint gap. can do.
