（産業上の利用分野）
本考案は、ビル等の天井面、特に曲面を形成す
る箇所に用いられる天井板に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ceiling plate used for a ceiling surface of a building or the like, especially a curved surface.
（従来の技術）
一般に、ビル等の天井面には、防火性に優れた
無機質繊維を主成分とした基板からなる天井板が
用いられている。また、ビル等の天井面は、意匠
的な変化を持たせるために周辺部等が曲面に仕上
げられることがあり、この曲面の箇所にも上述の
天井板が使用されることがある。(Prior Art) Generally, ceiling panels made of a substrate mainly composed of inorganic fibers with excellent fire retardant properties are used on the ceiling surfaces of buildings and the like. Further, the ceiling surface of a building or the like is sometimes finished with a curved surface around the periphery in order to give a design change, and the above-mentioned ceiling board is sometimes used also in the curved surface.
ところが、この場合、上述の天井板は、弾力性

方向に貼着したりしたものは知られている。 However, in this case, the above-mentioned ceiling board has poor elasticity and cannot be bent into a curved shape. As one means for this purpose, for example,
As disclosed in Japanese Patent No. 168750, a plurality of parallel cut grooves are carved on the back or front surface of the board to give it flexibility, and a coarse cloth is added to the back of the board for reinforcement. It is known that a paper cloth is pasted over the entire surface, or a tape-like paper cloth is pasted in a direction perpendicular to the cut groove.

布ロールの取り換え作業等煩雑で生産性が悪かつ
た。(Problem to be solved by the invention) However, in the above-mentioned method, the thickness of the ceiling panel is thicker than other ceiling panels by the thickness of the coarse cloth or tape-like paper cloth, so it is difficult to meet other ceiling panels. If they are constructed together, there is a problem that unevenness occurs, the joints stand out, and the finished appearance deteriorates. Furthermore, pasting coarse cloth or tape-like paper cloth requires two steps: an adhesive application process and an adhesive integration process, and the work of replacing coarse cloth or tape paper cloth rolls is complicated and has poor productivity. .
そこで、このような問題を解決するために、基
板の裏面に、切込み溝と共に該切込み溝と直交す
る凹条溝を刻設し、該凹条溝にテープ状紙布を貼
着することが考えられる。 Therefore, in order to solve this problem, it is considered to carve notched grooves and grooves perpendicular to the notched grooves on the back surface of the substrate, and to attach tape-like paper cloth to the grooves. It will be done.
しかし、この場合、更に生産性が悪くなる上に

込みムラが生じかつ接着層形成が妨げられて充分
な貼着力が発揮されず、その結果、テープ状紙布
による補強効果が十分に得られないという問題が
ある。 However, in this case, productivity is further deteriorated, and since the substrate itself, which is mainly composed of inorganic fibers, is fragile, the fragility becomes even more pronounced due to the cut grooves and grooves that are perpendicular to each other. If you hold the corners of the ceiling board, it may break due to shearing. In addition, when carving the grooves, fluff and fine powder are generated and the porous parts are exposed, so when attaching the tape-like paper cloth to the grooves, the adhesive has insufficient adhesive strength. However, even with adhesives, suction unevenness occurs and the formation of an adhesive layer is hindered, so that sufficient adhesion strength cannot be exerted, and as a result, there is a problem that the reinforcing effect of the tape-like paper cloth cannot be sufficiently obtained.

である。 In view of these points, the purpose of the present invention is to provide an appropriate method instead of pasting a tape-like paper cloth to grooves carved in the back or front surface of the substrate in a direction perpendicular to the grooves. It is an object of the present invention to provide a ceiling board capable of constructing a beautiful curved ceiling surface with excellent flexibility, strength, and productivity by embedding materials.

Even if this occurs and the porous portion is exposed, since the resin is applied to each groove 5 to form the resin layer 6, the resin will not penetrate well into the porous portion. As a result, the resin layer 6 is firmly fixed on the surface of the groove 5. Furthermore, the resin layer 6 is fixed by penetrating the side surfaces of the grooves 5 and the intersections of the cut grooves 4 with the grooves 5, so that the resin layer 6 and the substrate 1 are integrated. As a result, the strength of the ceiling board A is greatly increased. Therefore, even if a corner portion of the ceiling plate A is held while transporting the ceiling plate A, the ceiling plate A will not be broken due to shearing, and its handling becomes good.

At the same time, grooves are carved in the back surface of the ceiling board in a direction perpendicular to the grooves, and a resin layer having extensibility and flexibility is embedded in the grooves. It can be easily bent in the groove, and a beautiful curved ceiling surface can be constructed without creating a level difference between the ceiling surface and other adjacent ceiling surfaces. Furthermore, when embedding the resin layer in the grooves, the resin penetrates well into the porous portions of the grooves, and also the side surfaces of the grooves and the intersections of the cut grooves with the grooves. Since the resin layer and the substrate are easily integrated by penetrating and fixing, the strength of the ceiling plate is increased with good productivity, and shear failure during transportation can be reliably prevented.
