Conventionally, adjacent ceiling panels have been connected to each other in a manner as shown in FIG. 1, which is an explanatory diagram showing a cross section of a ceiling panel joint. In other words, in Figure A, a groove B is provided at the side end of a ceiling gypsum board A, and a suitable piece of Yatoi or the like is passed between the two grooves and fixed. This method will cause the ceiling board to crack. Also, as shown in figure B, glue the crosspieces d on both sides of the ceiling plasterboard,
Some have a groove b' on the side edge and pass the yaito fruit c between them, and since the crosspiece is mainly made of wood, even if the ceiling board and the yaite fruit are nonflammable, they will not be safe in the event of a fire. There is a possibility that the crosspieces will catch fire due to the heat from There are wooden crosspieces e and e′ glued together at positions where the leading edge is inside the leading edge of the wooden crosspiece, but in this case, the grooves are formed so that both wooden crosspieces butt against each other on the slope. In this case, a nail is driven into the edge of the field from part e to fix it, and the nail head is blocked by the top of the adjacent board and does not appear at the joint, but this is also the case in case b. Similarly, it can be ignited by fire from below.

ヤイト実には長尺物で薄く、かつ不燃性の材料

あつて耐熱性の点で充分ではない。
In reality, there are no long, thin, and non-flammable materials, and iron plates, such as iron plates, thin asbestos slate plates, and thin calcium silicate plates, are the most practical. Thin iron plates do not have sufficient heat resistance, as they will stretch and bend due to heat, and this heat will also be transmitted to the wooden beams and verandas, causing them to heat up and spread the combustion.

The present invention improves these points, and improves the heat resistance of ceiling panels such as gypsum board, calcium silicate board, asbestos slate board, and fireproof board without depending on the connection method described above. The structure of the ceiling panel was devised.

Reference numeral 1 denotes a non-combustible ceiling board material such as the above-mentioned gypsum board, calcium silicate board, asbestos slate (hereinafter simply referred to as ceiling gypsum board), and one of the side edges 2 on the back side of both side edges thereof is Another gypsum board 3 extending eave-like from the side edge is adhered, and at the other side edge 2', another gypsum board 3' is similarly adhered to the inner side of that side edge, and a ceiling gypsum board is attached. Backing materials 4, 4, which are easy to nail, are adhered to the upper surfaces of gypsum boards 2, 2' which are adhered on both side edges of gypsum boards 1, 2'.
The backing material 4 is suitably wood, plywood, or the like.

The connection of the ceiling panels of the present invention is shown in the cross-sectional diagram of FIG. The other gypsum boards 3, 3' bonded to the back side of both side edges of the ceiling gypsum board 1 and the front edges of the backing material 4 bonded thereon are shaped so as to butt against each other when connected. , in the vertical plane,
Or, on an inclined surface, or in a shape where the front edge of the other plasterboards 3, 3' is not easily damaged during handling,
For example, it may be arcuate as shown in FIGS. 2 and 3. 5 is a back crosspiece that connects both side crosspieces.

In this way, the joint part of the connection part is made of a fire-resistant material (for example, plasterboard) 3, 3',
Since the backing material 4 on top of it is made of wood, plywood, etc., it is easy to nail, and it can be firmly fixed to the edge of a field, without any possibility of cracking, and has sufficient strength, which significantly improves fire resistance. This is what I did.
