Next, the structure of each part of the above sound absorbing wall device, that is, the sound absorbing ceiling device will be described. 3 to 5 show the structures of the above-mentioned mounting metal fitting 10 and fixing metal fitting 11. The mounting member 10 is formed by bending a metal plate such as a stainless steel plate into a substantially U-shape, and its inner width is formed to have a size so as to be in close contact with both side surfaces of the lower frame member. . And this mounting bracket 1
A pair of cut-and-raised portions 21 are formed at the lower portions of both side wall portions 10a of 0 so as to project inward. Further, a pair of locking cut-and-raised pieces 22 are formed on the upper portions of both side wall portions 10a. These locking cut-and-raised pieces 22 have a tongue-like shape in which these side wall portions 10a are punched out in a U shape. In the initial state, as shown by the solid line in FIG. It only needs to be punched out, for example, to bulge inward slightly larger than the plate thickness of the fitting 10.

Such a mounting member 10 is fitted into the plate frame member 6 from below. In this case, the above-mentioned cut-and-raised portion 2
1 contacts the lower surface of the lower frame member 6 described above. After that, the locking cut-and-raised piece 22 is bent inward by a tool such as a screwdriver as shown by a chain double-dashed line in FIG. Therefore, the locking cut-and-raised pieces 22 engage with the upper surface of the lower frame member 6. As a result, the mounting bracket 10 can be easily mounted at any position on the lower frame member 6. A plurality of, for example, three screw holes 23 are formed in the bottom wall portion 10b of the fitting 10.

The fixing member 11 is formed by press-molding a stainless steel plate as shown in FIG. 3, and has a rectangular flat plate-shaped main body 25. A pair of fitting portions 26 are integrally projecting from both ends of the body 25, and a fitting portion 27 is integrally projecting from one side surface portion. These fitting portions 26 and 27 have a pair of claw portions, and these claw portions are bent into a shape that spreads downward. Further, a mounting hole 27 is formed in the body portion 25 so as to correspond to the screw hole 23 of the mounting member 10.

Therefore, the space on the upper side of the decorative plate 1, that is, the back surface side, and the space on the lower side of the decorative plate 1, that is, the space on the indoor side, communicate with each other through the communication path formed by the above-described gap.

The sound absorbing plate member 5 is constructed as shown in FIGS. 6 and 7. That is, the sound absorbing plate member 5 is formed of a porous material in which particles of a ceramic material are bound by a binder as described above. In this embodiment, alumina-based mullite particles are used as the ceramic particles, and the particle diameter is, for example, 0.5 mm.
To 1.0 mm are used. An epoxy adhesive is used as the binder, for example.

Further, in this embodiment, a reinforcing metal net 41 is embedded in a main body portion 40 made of a material obtained by binding such ceramic particles with a binder. As the wire net 41, for example, as shown in FIG. 6, an aluminum wire rod formed into a corrugated shape and joined is used. Then, such a wire net 41 is placed in a mold (not shown) for molding the sound absorbing plate member 5, the mixture of the ceramic particles and the binder as described above is filled from above, and compressed by a press. And heat to cure the binder. When manufactured by such a method, as shown in FIG. 7, the material in which the ceramic particles and the binder are mixed enters the inside of the mesh of the wire net 41, and the wire net is integrally embedded in the main body member 40.

Since such a sound absorbing plate member 5 is reinforced by the metal net 41, it has high strength and does not crack.
Further, since the mesh portion of the wire net 41 is a void, the sound absorbing effect of the sound absorbing plate member 5 is hardly deteriorated even when the wire net 41 is embedded. Further, the main body portion 40 made of a material obtained by binding such ceramic particles with a binder.
Has high heat resistance, nonflammability, and high fire resistance.
Further, such a material has an advantage that it is possible to obtain an arbitrary sound absorbing property by changing the diameter, the porosity, and other properties of the ceramic particles.

For example, FIG. 11 shows the results of measuring the sound absorption characteristics of the sound absorbing plate member of this embodiment by the reverberation chamber method. As shown in FIG. 11, this sound absorbing plate member exhibits flat sound absorbing characteristics over a wide frequency range. This embodiment is suitable for a sound absorbing ceiling device in a conference room, for example. That is, this embodiment can efficiently absorb noise in a wide range of frequencies, and has a flat sound absorption coefficient at each frequency, so that the timbre of a human voice that is a synthesized sound of a plurality of frequencies Does not change or become difficult to hear.

It should be noted that such sound absorbing characteristics should be set in accordance with the purpose of use of the sound absorbing wall device.
The sound absorbing plate member formed of the material in which the ceramic particles are bound with the binder has the sound absorbing characteristic as an arbitrary characteristic as described above by appropriately setting the diameter and the porosity of the ceramic particles as described above. There is an advantage that it can be easily set.

Incidentally, FIG. 12 shows the sound absorbing characteristics of the sound absorbing material of rock wool which has been conventionally used. As is clear from FIG. 12, such a material exhibits a characteristic that the sound absorption coefficient increases as the frequency increases, and the sound absorption plate member is a flat sound absorption plate member such as the above-mentioned ceramic particles bound with a binder. The characteristics cannot be obtained, and it is difficult to set the sound absorption characteristics to arbitrary characteristics.

Since the sound absorbing plate member 5 made of the porous material obtained by binding the above ceramic particles with the binder is used in the above-mentioned embodiments, the sound absorbing characteristics as described above are excellent. And there are many advantages.

That is, in such a sound absorbing ceiling device, a space is formed between the decorative plate 1 and the ceiling wall of the building frame. When the temperature of the room in which the ceiling device is installed rises, the air in the space expands, and when the temperature of the room drops, the air in the space contracts. Therefore, as the air in the space expands and contracts,
This air flows out into the room, and the room air flows into this space.

The sound absorbing plate member 5 is made of a porous material as described above, but has a large air flow resistance, and when air flows through the sound absorbing plate member 5,
There is great resistance. On the other hand, as shown in FIG. 5 described above, the space between the decorative plate 1 and the ceiling wall has the gaps 30, 31.
It communicates with the room through such a communication passage. Therefore, the air in this space flows out into the room through the communication passage formed of these gaps 30 and 31, or flows into the space from the room through this communication passage, and the small holes of the decorative plate 1 described above. 4 and the sound absorbing plate member 5 do not flow through. Therefore, static electricity is not generated in the decorative plate 1 and the sound absorbing plate member 5 due to the circulation of the air, and dust is not adsorbed on the edges of the small holes 4 of the decorative plate 1 to impair the appearance.

Further, since the sound absorbing plate member 5 has a sufficient sound absorbing function even if the plate thickness thereof is thin, the thickness of the entire sound absorbing ceiling device can be reduced. Further, the sound absorbing plate member 5 has a rigid plate shape, and it is sufficient to cut it to a predetermined size and dispose it on the back surface side of the decorative plate 1, and the construction is easy.

Further, since the sound absorbing plate member 5 is made of a material in which ceramic particles are bound with a binder,
Even if the ceramic particles are exfoliated, they do not float in the air. Therefore, unlike the conventional case where rock wool is used as a sound absorbing material, small pieces of fibers do not float in the air and adversely affect the human body.

Next, a method of constructing the sound absorbing ceiling device having the above structure will be described. First, the frame members 6 and 7 are attached to the ceiling portion of the skeleton of a building or the like on which the ceiling is constructed via the above-mentioned hanging metal fittings 8 and the like. In this case, the interval between the lower frame members 6 is set to be equal to the above-mentioned arrangement interval of the decorative plate 1. Since the lower frame member 6 is attached to the upper frame member 7 orthogonal to the lower frame member 6, it is easy to accurately adjust the interval between the lower frame members 6.

Next, the fittings 10 are attached to the lower frame member 6 so as to correspond to the dimensions of the decorative plate 1, that is, the corners of the decorative plate 1. The locking cut-and-raised pieces 22 of the mounting member 10 are along the both side wall portions 10a in a state before mounting. Therefore, the mounting member 10 can be easily fitted to the lower frame member 6 from the front side, that is, the lower side. Next, a tool such as a screwdriver is used to press these locking cut-and-raised pieces 22 and bend them inward. Therefore, the bent and raised locking cut-and-raised pieces 22 are locked to the rear surface, that is, the upper surface of the lower frame member 6, and the mounting metal fitting 10 is mounted at an arbitrary position of the lower frame 6.

In this way, these mounting fittings 10
After being attached at a predetermined position, the fixing metal fitting 11 is attached to the mounting metal fitting 10 with the screw 29. Then, the corners of the flange portion 1a of the decorative plate 1 are clamped and fixed between the fixing bracket 11 and the mounting bracket 10, and the decorative plate 1 is attached. After this, this fixing bracket 1
The decorative frames 2 and 3 are fitted into the fitting portions 26 and 27 of 1 to hide the mounting portions of these decorative plates 1.

In such a case, the above-mentioned sheet is laid inside a mold for molding the material 40a in which the above-mentioned ceramic particles are bound with a binder, and a material obtained by mixing the ceramic particles and the binder is filled on the sheet, and It can be manufactured by stacking another sheet from above and compressing and heating the mold.

In the second embodiment, this sheet 4 is used.
The sound absorbing plate member 5a can be reinforced by 2 and even if the ceramic particles are exfoliated, the ceramic particles are held by the sheet 42,
There is an advantage that it does not fall into the room through the small holes 4 of the decorative plate 1.

FIG. 9 shows the sound absorbing plate member 5b of the third embodiment. In this case, a material 40b obtained by binding the above-mentioned ceramic particles with a binder is contained in a bag body 44 formed of a sheet 43 made of the above-mentioned porous material. Also in this embodiment, the second
In the same manner as in the embodiment of 1., even if the ceramic particles are exfoliated from the material 40b, the particles are retained in the bag body 44, and the ceramic particles enter the room through the small holes 4 of the decorative plate 1. It never falls. The second and third embodiments have the same decorative plate mounting mechanism and the like as those of the first embodiment.

FIG. 10 shows a sound absorbing plate member 5c of the fourth embodiment. This is a product in which two sheets 45 and 46 made of the above-mentioned porous material wrap a material 40c obtained by binding the above-mentioned ceramic particles with a binder. That is, the edge of the one sheet 45 wraps around the edge of the material 40c, and the edge of the other sheet 46 overlaps the edge of the one sheet 45 so that the edge of the material 40c is overlapped. It wraps the department.
The edges of these sheets 45.46 are fixed by means of an adhesive, a pressure sensitive adhesive sheet or the like.

Furthermore, the present invention is not limited to the above embodiments. For example, the present invention is not limited to the sound absorbing ceiling device as described above, but can be applied to an interior wall device generally installed on a side wall of a room or space. In this case, a mechanism for fixing the sound absorbing plate member to the back side of the decorative plate may be added.
