的小さい難点がある。[Detailed Description of the Invention] The present invention relates to a ceiling board. Various types of ceiling panels are used, including glass fiber (glass wool) and rock wool (rock wool).Glass fiber ceiling panels are lightweight, nonflammable, and have excellent heat insulation and sound absorption properties, making them widely used. However, it has the disadvantage of relatively low rigidity.

子繊維製天井板は剛性が小さいため、その周縁部
を支持具で支持した場合、中央部にかなり大きい
垂れ下がりを生じ外観が不良となり易い。 In recent years, with the spread of system ceilings, large-sized ceiling panels have come to be used. However, since glass fiber ceiling panels have low rigidity, when supporting the periphery with supports, the center This tends to cause considerable sagging in the parts, resulting in poor appearance.

なる傾向を有する。 Generally, in order to obtain a good appearance, it is necessary to keep the amount of sagging in the center part to 0.5% or less of the short side. The size of the sagging depends on the size of the glass fiberboard,
It changes depending on the thickness, density, etc., and the larger the size or the smaller the thickness or density, the greater the amount of sagging tends to be.

1.200mmの天井板の中央部の弛みの大きさは15mm

を30mmとする必要がある。 Therefore, in the case of a large (large dimension) ceiling board, if you try to reduce the sagging, it is necessary to make it thicker or denser than in the case of a small ceiling board. This results in high production costs. For example, when using glass fiberboard with a thickness of 15 mm and a density of 48 Kg/ m3 , when supporting the four sides of a ceiling board with a size of 450 mm x 900 mm, the sagging in the center part is practically 0, but the sagging in the center part is 1.200 mm. mm×
The size of the slack in the center of the 1.200mm ceiling board is 15mm.
, and in order to make the slack size 6 mm, the thickness needs to be 30 mm.
本考案はこのような難点を解決するための研究
に基づく新たなる提案である。 This invention is a new proposal based on research to solve these difficulties.
次に本考案を添付図面に就いて詳細に説明す
る。 The present invention will now be described in detail with reference to the accompanying drawings.

る。 In the first embodiment shown in FIGS. 1 to 3, 1 is a rectangular ceiling board, which is made up of a glass fiberboard 2 and a synthetic resin film 4 attached to one side 3 (back side in FIG. 1) of the ceiling board. It is configured. Suitable glass fiberboards have a density of 24 to 200 Kg/m 3 and a thickness of about 10 to 150 mm, and as synthetic resin films, vinyl chloride films with a thickness of 40 to 200 μm are suitable, and vinyl chloride films are preferred. is provided with an embossed uneven pattern (not shown). The synthetic resin film 4 and the glass fiberboard 2 are preferably bonded together using a rubber-based, vinyl acetate-based hot melt adhesive, or a rubber-based, vinyl acetate-based or other solvent-based adhesive.

近いほぼ一定の曲率を有するものが適当である。 The glass fiberboard 2 is curved smoothly and slightly in the longitudinal direction so that the film-attached surface of the glass fiberboard, that is, the back surface 3 in FIG. 1, is a concave surface. It is appropriate that the degree of curvature be approximately the same as the sagging (sag) that occurs when the four sides of a conventional ceiling board of the same size are supported horizontally by frame fittings. The shape is suitably circular or has a substantially constant curvature close to this.

る。 The curved ceiling board like this is made of glass wool mat (uncured mat) with an uncured binder added.
It can be manufactured by pressing and heating with a press having a predetermined shape to harden the binder. Alternatively, a flat glass fiberboard is manufactured by curing the binder of uncured pine, and a synthetic resin film is attached to the glass fiberboard with tension applied to the film, and the elastic restoring force of the film causes the glass fiberboard to form. It can be manufactured by bending.

うることができる。 When the ceiling board 1 is placed on the lower flange portion 5 of the rod of a rectangular frame metal fitting formed by assembling I-beam rods of the same size as the ceiling board 1 with the film side facing down, the ceiling board 1 is curved upward along the longitudinal direction (that is, so that the surface to which the film is attached becomes a concave surface), so that only the short side 6 of the ceiling board 1 contacts the flange portion 5, and the long side 7 is slightly raised. However, as the ceiling board 1 deforms and bends downward due to its own weight, the long side 7 becomes almost straight, and the ceiling board is supported by the flange portion 5 on its long and short sides. . In this state, the hanging force caused by the ceiling board 1's own weight is offset by the stress caused by the above-mentioned deformation of the ceiling board 1, so that the ceiling board 1 does not sag downward, and its density and thickness are reduced. A good appearance can be obtained even in the case of small and large ceiling panels.
第４図はほぼ球面状に彎曲せしめた第２実施例
であり、その製造方法、構成は第１実施例と同様
なので、同一符号を付し詳細な説明は省略する。 FIG. 4 shows a second embodiment which is curved into a substantially spherical shape, and the manufacturing method and structure thereof are the same as those of the first embodiment, so the same reference numerals are given and detailed explanation will be omitted.
第２実施例の天井板１を第１実施例と同様なフ

垂れ下り力は天井板１の変形によつて生ずる応力

い。 When the ceiling plate 1 of the second embodiment is placed on the flange portion 5 similar to that of the first embodiment, only the four corners of the ceiling plate 1 initially come into contact with the flange portion, but due to its own weight it moves downward. The ceiling board 1 deforms and becomes planar and is supported by its long and short sides, and the hanging force due to the ceiling board 1's own weight is balanced with the stress generated by the deformation of the ceiling board 1, and the ceiling board 1 does not sag downward.

が外観を損わない限度において彎曲の程度をこれ
より若干小とし、或は彎曲の程度を若干大とする
（この場合硝子繊維板に与えた彎曲が外観を損わ
ない程度僅かに残存する）こともできる。 In the above explanation, when the ceiling board is supported horizontally with the surface to which the synthetic resin film is attached facing downward, the sagging due to its own weight and the stress due to the deformation of the ceiling board are offset, and the ceiling board is supported horizontally so that the ceiling board is horizontal. Although we have explained that the degree of curvature should be made slightly smaller than this, or the degree of curvature should be slightly larger, as long as the sagging of the ceiling board does not damage the appearance (in this case, the degree of curvature given to the glass fiberboard may remain slightly to the extent that it does not impair the appearance).

くは３〜30mmならしめるのが適当である。 Furthermore, when the slightly curved ceiling panel of the present invention is placed on a horizontal table with the surface to which the synthetic resin film is attached (indoor surface) facing upward, the four corners of the ceiling panel will slightly rise above the table; It is appropriate that the size of the film be 1 to 50 mm, preferably 3 to 30 mm.
