Further, the support body 20 may be, for example, a front square frame shape fixed along the back surface of the frame body 11 or a box shape with a bottom, and supports the frame body 11. Just do it. Further, the support 20 may be a simple plate shape, and a recess may be formed in the central portion to form the storage portion 21. And as a material of the said support body 20, for example, various wooden board bodies, such as a plywood, a wood fiber board, and a particle board, or inorganic board forms, such as a rock wool board, a glass wool board, and a volcanic glassy multilayer board It may be a body. In addition, it is preferable that 50 to 80% of the support body 20 is the storage portion 21 in the found area. This is because if the storage portion 21 is less than 50%, the effect of the functional storage material 30 stored inside is reduced, and if it exceeds 80%, it is difficult to maintain a desired strength.

  The functional storage material 30 may be stored in the storage unit 21 formed by the support 20 and has at least a sound absorption performance. For example, the mat-shaped synthetic resin foam, the nonwoven fabric, and the woven fabric Sound absorbing materials such as glass wool, rock wool, and insulation board may be used. Sound absorption performance, such as insulation boards, non-woven fabrics made by kneading activated carbon and / or silica gel into synthetic resin, or synthetic resin foams made by kneading activated carbon and / or silica gel into synthetic resin and foaming And a mat molded product having both humidity control performance and the like. Further, if the functional storage material 30 is a deformable material such as a non-woven fabric or foam, the functional storage material 30 has a front shape having a larger area than the opening 12 of the frame 11 and is pushed in from the opening 12 for storage. You may store in the part 21. FIG.

  The decorative panel 40 has a front shape covering the surface of the frame body 11 and is detachably attached to the surface of the frame body 11, and has a sound absorption function, a sound reflection diffusion function, and a humidity control function. Although it is preferable, it is sufficient if it has at least a sound transmission function. For this reason, as a decorative panel, for example, as shown in FIG. 4A, a woody perforated panel such as a plywood, an insulation board, an MDF (medium specific gravity fiber board), a hard board or the like having a large number of through portions, a volcanic property Examples thereof include a glassy multi-layer perforated plate, a low-specific gravity inorganic perforated plate such as foamed concrete, a molded plastic perforated plate, or a perforated plate made of a metal material such as aluminum. The surface of the decorative panel 40 may be flat, or various uneven patterns may be formed on the surface.

Further, the through-portion 41 of the decorative panel 40 only needs to be able to easily transmit moisture, sound, and light, and the shape thereof is not limited to a through-hole such as a round hole or a square hole, and is a slit. May be.
Furthermore, as long as moisture, sound, and light can be easily transmitted, the surface and / or the back surface of the decorative panel 40 provided with the penetrating portion 41 may be covered with a cloth or a nonwoven fabric. However, if it is covered with a thin sheet-like thin film such as vinyl chloride, polyethylene terephthalate, olefin, etc., only the sheet-like thin film covering the penetration part 41 is partially removed in order to prevent sound and moisture from passing through the penetration part 41 It is necessary to keep it.
As shown in FIG. 4B, the decorative panel 40 has juxtaposed sound-absorbing materials 42 made of elastic foamed resin and formed in a mountain-shaped cross section on the surface of a plate-like substrate having a large number of through portions. In addition, the surface of the sound absorbing material 42 may be covered with a nonwoven fabric. In this case, it is preferable that the sound transmitted from the vicinity of the mutually abutted portions of the ridges formed in the mountain-shaped cross section passes through the penetrating portion of the plate-like substrate and is absorbed by the functional storage material.
If the decorative panel 40 is a metal material, for example, as shown in FIGS. 4C and 4D, a plurality of extruded metal members 43 may be arranged in parallel at regular intervals to form a slit. . In particular, when the metal material is an aluminum material, it is preferable because it is lightweight. When reflecting and diffusing sound, for example, irregularities having a mountain-shaped cross section may be provided on the surface, or irregularities may be formed by arranging bars having a triangular cross section at a predetermined pitch.

  In addition, in order to improve the cosmetic properties of the decorative panel 40, the surface thereof may be colored and painted. Further, when the decorative panel 40 itself has humidity control performance, humidity control such as diatomaceous earth or silica gel is used. The material may be painted.

  The decorative panel 40 has mounting grooves 42 (FIGS. 2B and 2C) for mounting the insertion fittings 43 along the edges of two adjacent sides of the four sides of the back surface. A pair of latches 45 is attached to the edge of the opposite side that faces the attachment groove 42 to which the insertion fitting 43 is attached. As in the present embodiment, mounting grooves 42 are provided on two adjacent sides of the four sides, and the insertion fitting 43 is attached to one of the two sides, and the latch is placed on one of the other two sides. If it attaches so that it may oppose 43, there exists an advantage that the wall surface of a different design can be formed with one type of decorative panel 40 by changing the attachment direction of the decorative panel 40 by 90 degree | times.

  The decorative panel 40 may be covered with a transparent plate (not shown) having a plurality of through-holes so that a pattern directly below can be seen. Examples of the transparent plate include transparent resin materials such as acrylic, polyester, polycarbonate, and polyacrylate, and these may be colored in a desired color within a range that does not hinder visual observation.

Next, the assembly process of the above-described component members will be described.
First, as shown in FIG. 2A, the lower crosspiece member 3 to which the bracket 2 is fixed is fixed to the wall 1 with wood screws, and then the lower end 14 of the frame plate 11 is engaged with the bracket 2 ( 2D), a plurality of the supports 20, 20 are abutted so as to be adjacent to each other (FIG. 5). Next, the relay metal fittings 4 fastened to the intermediate horizontal beam member 5 by screws are engaged with the upper end portions 13 of the plurality of frame plates 11 (FIG. 2C), and the intermediate horizontal beam member 5 is attached to the wall body 1 by a tree. The frame body 11 is fixed to the wall body 1 by screwing. Further, the same operation as described above is repeated, and the frame body 11 is stacked. The lower end portions 14 of the other plurality of frames 11 are respectively engaged with the upper end portion of the relay metal fitting 4 and the support bodies 20 and 20 are abutted against each other. Then, the lower end portion of the support fitting 6 fixed to the upper horizontal cross member 7 with a wood screw is engaged with the upper end portion 13 of the frame plate 11 (FIG. 2B), and the frame body 11 and the upper horizontal cross member 7 are connected to the wall. Secure the body 1 with wood screws.

  Then, as shown in FIG. 3, a parting piece 8 having a T-shaped cross section is attached between adjacent frame plates 11, and parting parts 9 a and 9 b are respectively attached to the exposed outer surfaces of the supports 20 and 20.

  Next, the functional storage material 30 is inserted into the storage portion 21 of the support 20 from the opening 12 of the frame 11. Then, as shown in FIG. 2C, the insertion portion 43a of the insertion fitting 43 fixed to the back surface of the decorative panel 40 is inserted into the receiving portion 4a of the relay fitting 4 from obliquely below, and then the decorative panel 40 is attached to the frame body 11. The latch 45 is fitted into the receiving member 15 and locked. Similarly, as shown in FIG. 2B, the insertion portion 43a of the insertion fitting 43 fixed to the back surface of the other decorative panel 40 is inserted into the receiving portion 6a of the support fitting 6 from obliquely below, and then the decorative panel 40 is mounted. By pressing against the frame 11, the latch 45 is fitted and locked to the receiving member 15. Thereafter, a wall structure having excellent sound absorption and humidity control can be obtained by performing the same construction and attaching the wall material unit 10 to the wall body 1.

  When the decorative panel 40 or the functional storage material 30 is replaced, the portion of the front surface of the decorative panel 40 to which the latch 45 is attached is pressed again to release the locked state. Next, while rotating the lower end edge of the decorative panel 40, the latch 45 is pulled out from the support 15 and is pulled down obliquely to insert it from the insertion receiving portion 4a (6a) of the relay metal fitting 4 (support metal fitting 6). The insertion part 43a of the metal fitting 43 is pulled out and removed.

As described above, the metal member is not used for the support 20 and the crosspiece members 3, 5, and 7 for the following reason.
That is, when a metal member is directly attached to the wall 1 in the room, condensation often occurs on the surface of the metal member due to a sudden change in temperature and humidity in the room. In particular, when the functional storage material 30 is provided with a humidity control function, moisture on the indoor side tends to concentrate and condensation tends to occur. In such a case, when a metal member is directly attached to the wall surface, spots and discoloration are likely to occur on the wall surface due to condensation occurring on the surface of the metal member. Further, when the metal member is directly attached, the wall surface is easily damaged. Therefore, in order to solve such a problem, a wall surface structure is configured by providing a wooden member on the back surface of the metal fitting. Here, “wood” means wood material as a main material. For example, wood, plywood, LVL, particle board, insulation board, MDF, hardboard, etc., wood powder and polyethylene, Examples thereof include a wood powder extruded resin rod mixed with a synthetic resin such as polypropylene and vinyl chloride.
In addition, the wooden support body and the horizontal beam member may have a substantially rectangular cross section or a substantially trapezoidal shape, and the front surface preferably has the same width as that of the metal fitting. And the uneven | corrugated process for a decoration may be given to the part visible from indoor space.

  In addition, if lighting using an LED as a light source is provided inside the frame, a more stylish space design becomes possible. Since the LED generates little heat, the use of a polyester resin non-woven fabric or foam as a functional storage material does not interfere with humidity control and does not deform the decorative panel. There is an advantage that a material unit can be provided.

The second embodiment is substantially the same as the first embodiment described above, and will be described focusing on the differences. Note that the same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

Furthermore, while only the decorative sheet covering the through-hole was removed, a thin polyester nonwoven fabric of 20 g / m ² was attached to the back surface of the substrate. And the mounting groove of width 2mm was provided in the position of 20 mm inside from the outer peripheral edge part of the back surface among two adjacent sides of the base material. Then, an insertion fitting extruded was inserted into the mounting groove and fixed with a wood screw. Finally, by providing a pair of attachment holes on each of the other two remaining sides of the base material, and attaching dowels to the attachment holes provided on the opposite sides opposite to the one side on which the insertion fitting is attached, A decorative panel 40 was obtained.

  Five vertical cedar bars 60 mm long, 60 mm wide and 1370 mm long were juxtaposed in parallel at predetermined intervals in the vertical direction on the wall. Further, cedar bars 60 mm in length and 60 mm in width were attached as horizontal bars for attaching the decorative panel in a flat and lattice manner between the vertical bars. In addition, the column position in the wall was previously detected by an ultrasonic sensor, and the beam member corresponding to the column position was fixed with a particularly long wood screw.

  Next, an aluminum receiving metal fitting was attached so as to be bridged over all of the horizontal beam members positioned at the lowest position among the horizontal beam members. And like the above-mentioned 1st Embodiment, the lower end part of the some frame was engaged and assembled | attached to the said metal fitting. Furthermore, while engaging an intermediate | middle metal fitting with the upper end part of the said frame, the said frame was fixed by screwing the said intermediate | middle metal fitting to the said horizontal crosspiece member.
