It is set to 2. Note that one module length is a length corresponding to a conventional half space (one tatami mat is one space × half space), and is specifically set to 800 mm, 910 mm, 1000 mm, or the like. The total of 20 movable members 2 is 5
The movable members 2 are divided into four groups 2A to 2D, and the adjacent main members 1 and 1 are connected to each other by the movable members 2 of the groups 2A to 2D.
Each of the movable members 2 is a square member having the same thickness w as that of the main body member 1 and has a length of (2L−d / 2−t /
2-5w) / 4. A guide hole 2a having a predetermined diameter and a notch groove 2 having a predetermined width are provided at both ends of the movable member 2.
b (FIG. 2). Also, the corners of both ends of the movable member 2 are rounded off with a radius,
The ceiling panels can be folded and pushed up as needed. The corners of the movable member 2 may be cut off both corners as shown in FIGS. 1 and 2, or only one corner may be cut off as shown in FIGS.

The connecting member 3 is formed by bending a metal plate having a thickness of about 1.5 mm. The connecting member 3 is attached to the main members 1A and 1E while being connected to the connecting member 3 'and the other main members 1B to 1D. Both connecting tools 3 are used (see FIG. 3). Both the connecting member 3 and the one connecting member 3 'are different depending on whether the flange portion 3B extends in both directions or only in one direction, but in any case, the mounting hole is formed in the base portion 3A. 3a are provided, and pin holes 3b, 3
b is provided. The connecting member 3 is fixed to the main body member 1 by driving the nail 4 into the mounting hole 3a. The main body 1 and the movable member 2 are connected by driving the nail 5 into the guide hole 2a of the movable member 2 after introducing the flange 3B of the connector 3 into the cut groove 2b of the movable member 2. (See FIG. 4). Here, the pin hole 3b of the flange portion 3B is formed larger than the outer diameter of the nail 5,
Since the cut groove 2b is formed to be slightly larger than the thickness of the flange portion 3B and the corner of the movable member 3 is formed in a round shape, the connector 3 and the movable member 2 are pin-connected with the nail 5. become. As described above, in the ceiling panel of the present invention, since the movable member 2 is rotatably connected to the main body member 1, after manufacturing the ceiling panel, the main body members 1B and 1D are moved to one side. By simply pressing and fixing the other three main body members 1A, 1C, and 1E or pulling them toward the other side, they can be easily folded. The movable member 2
When only one corner is dropped at the end of the movable member 2, it is necessary to reverse the corner to be cut at both ends of the movable member 2 and attach the movable member 2 in the opposite direction for each of the adjacent groups 2A to 2D. . That is, as shown in FIG. 5B, the first group 2A has a lower corner dropped at the end contacting the main body member 1A, and an upper corner dropped at the end contacting the main body member 1B. On the other hand, in the second group 2B, the upper corner is dropped at the end contacting the main body member 1B, and the lower corner is dropped at the end contacting the main body member 1C. The same applies hereinafter, and the third and fourth groups 2C and 2D are
