TECHNICAL FIELD The present invention relates to a decorative inorganic fiber interior material.

[0002]

2. Description of the Related Art Conventionally, a mat made of inorganic fibers such as glass wool and rock wool to which 2 to 10% by weight of a binder containing a thermosetting resin such as an uncured phenol resin as a main component is added is subjected to heat compression molding. For example, thickness 10 to 10
A cosmetic inorganic material that looks good by applying an inorganic paint or attaching a decorative sheet such as a vinyl chloride resin film or glass cloth to the surface of an inorganic fiber board having a thickness of 0 mm and a density of 10 to 120 kg / m ^3. Fiberboard is known. These are office buildings, large stores,
It is used as an inner wall material for buildings such as gymnasiums and exhibition halls, and as an interior material such as ceiling materials. In particular, the decorative inorganic fiber board made of glass wool is widely used because it is lightweight among many decorative inorganic fiber boards and is excellent in heat insulating property, sound absorbing property, and flame retardancy.

[0003]

However, the conventional decorative inorganic fiber board is lighter in weight than the inorganic type interior material such as gypsum board, but its rigidity is relatively low, and therefore, when the size is increased. There is a problem in that the center portion is easily bent due to its own weight, which impairs the aesthetic appearance and thus limits the increase in area.

Further, since the conventional decorative inorganic fiber board has higher flexibility than the inorganic type interior material such as gypsum board, the fiber is not completely cut when slit to a predetermined size, or the side edge is not cut. The corners were rounded and the side edge lines were bent, so the side edge shape accuracy was likely to be low. For this reason, there is a problem in that an irregular gap may occur between the adjacent decorative inorganic fiber boards after the construction, resulting in poor appearance. Further, there is a problem in that, due to the inflow and outflow of air through the gap as described above, dust in the room or on the back of the ceiling is likely to adhere to the peripheral portion of the gap and become dirty, which tends to impair the appearance.

As a means for improving the above-mentioned drawback that the bending is likely to occur, for example, Japanese Utility Model Laid-Open No. 62-158014.
The publication discloses a technique in which a reinforcing material having a T-shaped cross section is embedded in the surface of the mineral fiber board opposite to the interior surface to form the interior material. Also, the actual Kaihei 2-36518
The publication discloses a technique of forming a ceiling board by press-fitting, loading, and adhering a plate-shaped body having a substantially pentagonal cross-sectional shape from the back surface of the glass wool plate without protruding outside. Further, Japanese Utility Model Application Laid-Open No. 5-34220 discloses a technique of constructing a ceiling material by inserting a reinforcing material into a concave groove formed in a groove orthogonal to the fiber direction of a rock wool plate. However, these techniques can prevent the bending of the central portion of the inorganic fiber board, but cannot solve the problem that the side edge shape accuracy is low.

On the other hand, as means for solving the problem that the shape accuracy of the side edge is low, for example, in Japanese Utility Model Publication No. 63-37366 and Japanese Utility Model Publication No. 63-46568, a shape is formed on the side edge of a plate-shaped glass fiber felt. A technique is disclosed in which a holding piece is applied and one side surface of the glass fiber felt and the shape holding piece are covered with a woven cloth to form an adiabatic sound absorbing plate.
However, although these techniques can solve the problem of the side edge shape accuracy, they are not sufficient for improving the tendency of the central portion to bend.

Further, when a decorative inorganic fiber board is applied as a ceiling material, a cross method is adopted, and a gap between adjacent decorative inorganic fiber boards caused by the low shape accuracy of side edges does not appear on the indoor side. Techniques for doing so are known. The cross construction method is a construction method in which bar materials made of metal or plastic with a T-shaped cross section are connected in a grid pattern, and the ceiling material is placed on a frame formed by suspending and supporting the bar material from the ceiling slab for construction. The frame looks like a lattice from the room side. With this cloth construction method, mounting the ceiling plate,
Since it is easy to remove, it has excellent workability and maintainability, but on the other hand, the appearance of the frame that looks like a lattice from the inside tends to be unfavorable.

It is an object of the present invention to provide a decorative inorganic fiber interior material which can solve the above-mentioned problems of the prior art.

FIG. 4 is a sectional view showing an example of a state in which a plurality of decorative inorganic fiber interior materials 1 according to the first embodiment of the present invention described above are connected by using a member for connection. FIG.
In (A), the groove 23 of the adjacent decorative inorganic fiber interior material 1,
By inserting a bar 6 having a T-shaped cross section into 23, adjacent decorative inorganic fiber interior materials 1, 1 are connected to each other. When the decorative inorganic fiber interior material 1 is constructed as a ceiling plate as shown in FIG. 1, the bar 6 is connected to the ceiling slab via a hanging bolt or the like not shown. Further, in FIG. 4 (B), the bars 7 are inserted into the grooves 23, 23 of the decorative inorganic fiber interior material 1 to connect the adjacent decorative inorganic fiber interior materials 1, 1 to each other. In such a connected state, the bent portion 32 of the shape-retaining member 3 applied to the entire surface of the groove 23 functions like a rib to function as a reinforcing member for the inorganic fiber board 2 to prevent bending.
As compared with the case where a flat plate-shaped or rod-shaped reinforcing material is used, even a lightweight shape-retaining member can prevent bending more than equivalent. Therefore, in the present embodiment, it is preferable to apply the shape retaining member 3 to the entire surface of the groove 23 in order to enhance the effect of preventing the shape retaining member 3 from bending and prevent damage to the groove 23 itself.

The side surface portion 22 to which the shape-retaining member 3 is applied and fixed is a surface that constitutes at least two long sides when the planar shape of the decorative inorganic fiber interior material 1 is rectangular,
