Description

  The present invention relates to an inner wall installed on the indoor side of a building represented by a wooden house. More specifically, the present invention relates to a floor, a structural wall, a pillar, etc. (hereinafter collectively referred to as “structure”). .) To an attachment member for attaching a face plate such as an inner wall plate, and an interior structure using the attachment member.

  Noise from the upper floor has long been one of the major problems in buildings. In the case of buildings, it is no exaggeration to say that most of the noise received on the lower floor is due to solid sound, except for airborne sound. Conventionally, it has been a problem to reduce (that is, attenuate) the solid sound.

  Solid sound is sound generated by a wave that propagates through a solid as a result of the vibration of the solid when an impact is applied to the solid. This solid sound is emitted into the room and is transmitted to people as noise by vibrating the air. For example, when a person jumps up and down on the upper floor, this acts as an impact on the floor, and solid sound propagates through the floor, and noise is generated by releasing this solid sound to the lower floor.

  In addition, solid sound is emitted directly from an impacted solid (for example, a structure) and becomes noise, and solid sound is emitted after propagating from the structure to another structure and becomes noise. It is roughly divided into the following solid sounds. Of the solid sounds, the secondary solid sound propagates through all the continuous structures, so its propagation path is complicated, and the low frequency component is dominant and the wavelength is large. It was difficult.

  Various proposals have been made so far in order to solve the problem of reducing noise. For example, Patent Document 1 shown below proposes a countermeasure technique for solving this problem with noise transmitted from the upper floor to the lower floor of the building as a problem. is doing.

JP 2010-265619 A

  Patent Document 1 proposes a floor structure in which a damper is attached to a floor beam that supports the floor material, and a sound absorbing material is provided between the floor beam and the floor beam. This damper is composed of two damper members divided into upper and lower parts, and floor vibrations are suppressed by making the natural frequencies of these two damper materials the same.

  However, in Patent Document 1, it is necessary to install a damper having a divided structure, and it takes a troublesome manufacturing and installation, that is, there is an aspect that is difficult to adopt, that is, a period and cost for construction increase. Furthermore, when installing a ceiling board with a combination of a field edge, a field edge receiver, and a suspended tree, which is a general structure, the distance between the upper floor and the ceiling board is widened. It ’s hard.

  The subject of this invention is solving the problem which a prior art has. That is, it is possible to attenuate solid sound (especially secondary solid sound) without the need for members other than those necessary for attaching a face plate (for example, a ceiling plate) to a structure (for example, an upper floor). It is in providing an attachment member and the interior structure using this attachment member.

  The present invention has been made by paying attention to an attachment member necessary for attaching a face plate (for example, a ceiling plate) to a structure (for example, an upper floor), and the structure and the face plate which are the original functions of the attachment member. In addition to the mounting function, a noise reduction function for attenuating solid sound by its elastic deformation has been developed to provide a combination.

  The face plate mounting member of the present invention is provided between a structure (which constitutes a part of a building) and a face plate (mostly installed on the indoor side of the structure). It is the attachment member used in order to attach to. Furthermore, it is provided with an installation surface for installing the face plate, a locking surface for fixing to the structure, and a bent portion formed between the installation surface and the locking surface, and the installation surface is more in the axial direction than in the width direction. It has a long band shape, and the bent portion is provided on both ends of the installation surface in the width direction and has a first folded portion and a second folded portion where the bending direction is reversed. Formed in the order of the first folded portion to the second folded portion so as to hang down from the first folded portion, the first folded portion is folded inward in the width direction, and the second folded portion is folded outward in the width direction. Is continuously provided at the outer end portion of the second folded portion and is substantially parallel to the main body surface, and can absorb and reduce sound from the structure mainly by elastic deformation of the bent portion due to vibration of solid sound.

  The face plate mounting member of the present invention has a “first interval” from the inflection point (the point at which the first folded portion and the second folded portion are connected) to the installation surface. Assuming that “2 intervals”, one of the “first interval” and the “second interval” is shorter than the other, thereby forming a narrow gap portion in the first folded portion or the second folded portion. You can also. In this case, a buffer member made of an elastic body can be held in the narrow gap portion.

  The face plate attaching member of the present invention may be provided with an elongated hole extending in the axial direction in the vicinity of an inflection point (a point where the first folded portion and the second folded portion are connected).

  The interior structure of the present invention is an interior structure composed of a face plate mounting member. The face plate attachment member is a face plate attachment member according to any one of claims 1 to 4, and is fixed to the structure body with a locking surface and is provided with a face plate on the installation surface. The interior structure of the present invention is a structure in which a plurality of face plate mounting members are fixed to the structure substantially in parallel, and face plates are installed on these face plate mounting members, and the structure is formed by elastic deformation of the bent portion of the face plate mounting member. It is the structure which can reduce the solid sound from.

The face plate mounting member and the interior structure of the present invention have the following effects.
(1) Since the bending part which comprises a faceplate attachment member has the 1st folding | turning part and 2nd folding | turning part which a bending direction reverses, it can be elastically deformed easily. As a result, the solid sound can be attenuated and the sound pressure level of the radiated noise can be reduced, so that the indoor noise level is reduced and the reverberation time is shortened.
(2) Since no other members are required other than the face plate attachment member, which is a member necessary for attaching the face plate to the structure, the labor of manufacturing and installation is reduced, resulting in a shortened construction period and cost. It is reduced.
(3) The first interval from the inflection point (the point at which the first folding portion and the second folding portion are connected) to the installation surface is made smaller than the second interval from the inflection point to the locking surface, If it is a face plate mounting member that forms a narrow gap in the first folded portion, it can be easily installed even when the distance between the structure and the face plate is small, and the face plate is firmly fixed to the mounting member. It is possible.
(4) If a buffer member made of an elastic body is held in a narrow gap formed in the first folded portion (or the first folded portion), the solid sound can be further attenuated, and the sound of radiated noise The pressure level can be further reduced.
(5) If the face plate mounting member is provided with an elongated hole extending in the axial direction near the inflection point, it can be more easily elastically deformed, so that the solid sound can be further attenuated, and the sound pressure of the radiated noise The level can be lowered.

[Embodiment]
An embodiment of a face plate mounting member and an interior structure of the present invention will be described with reference to the drawings.

(overall structure)
FIG. 1 is a perspective view of a state in which the face plate mounting member 1 of the present invention is installed on the ceiling surface 2a as viewed from below. The face plate as used herein refers to a wall plate or floor plate that is attached to the indoor side of a structure such as a floor, a structural wall, or a pillar that constitutes a building, and the face plate attachment material 1 is for attaching the face plate to the ceiling surface 2a. belongs to. As shown in this figure, the face plate mounting material 1 is fixed to the ceiling surface 2a, the face plate is installed on the face plate mounting material 1 (for convenience, the face plate is omitted in this figure), so to speak, the face plate is interposed via the face plate mounting material 1. And attached to the ceiling surface 2a. The present invention is a face plate attachment member 1 for attaching a face plate to a structure and an interior structure using the face plate attachment member 1, and the structure is not limited to the ceiling 2 as a matter of course. In the example, the face plate is attached to the ceiling.

  As shown in FIG. 1, the face plate mounting member 1 is a long member having a substantially quadrangular shape in a plan view and having a longitudinal direction. Hereinafter, for the sake of convenience, the longitudinal direction is referred to as an “axial direction”, and the direction orthogonal to the axial direction is referred to as a “width direction”. In FIG. 1, the axial direction is indicated by an arrow X, and the width direction is indicated by an arrow Y.

  FIG. 2 is a cross-sectional view of the face plate mounting member 1 cut in the width direction. For convenience, this figure is shown upside down from FIG. As shown in FIG. 2, the face plate mounting member 1 includes an installation surface 3 disposed near the center, two locking surfaces 4 provided on both ends of the installation surface 3, and the installation surface 3 and the respective locking surfaces. 4 is formed with two bent portions 5 provided between the two. In addition, the installation surface 3 and the locking surface 4 have a substantially straight axis in a cross-sectional view, and each axis is substantially parallel but is not arranged in the same straight line. The installation surface 3 and the locking surface 4 are arranged so as to have different heights, such as the surface 3) and the lower stage (the locking surface 4 in FIG. 2).

  As shown in FIG. 1, the face plate mounting member 1 is fixed to the ceiling 2 with two locking surfaces 4 in contact with the ceiling surface 2 a. At this time, the screw holes 6 are previously provided in the axial direction of the locking surface 4 at a predetermined interval, and the face plate mounting member 1 can be screwed to the ceiling surface 2a using this. Of course, not limited to this, the face plate mounting member 1 can be fixed to the ceiling surface 2a by known fixing means used conventionally.

  Further, as shown in FIG. 1, the installation surface 3 of the face plate mounting member 1 may be provided with a width groove portion 7 a extending in the width direction and shaft groove portions 7 b arranged at both ends in the width direction. By providing these with the width groove portion 7a and the shaft groove portion 7b, the section modulus of the installation surface 3 can be increased, and harmful local deformation can be prevented. A large number of holes or fine convex and concave portions provided on the installation surface 3 are driving holes 8 for guiding a driving nail used when the face plate is installed.

  In general, noise from directly above the floor is generated when an impact applied by striking or the like is transmitted as a solid sound to the downstairs. More specifically, the applied impact propagates through a structure such as a floor or a peripheral wall (the propagation speed is also referred to as several thousand meters per second), the solid sound emitted from the structure vibrates the air, and the face plate As a result, it is transmitted to the downstairs (room) as a primary solid sound. On the other hand, since the solid sound propagated through the structure is directly transmitted to the face plate, the face plate vibrates accordingly, and as a result, is transmitted to the downstairs as a secondary solid sound. These primary solid sounds and secondary solid sounds are synthesized and transmitted as noise to people downstairs.

  In the present invention, the configuration as shown in FIGS. 1 and 2, that is, the bent portion 5 of the face plate mounting material 1 is easily elastically deformed, and as a result, the face plate is elastically fixed to the ceiling. Solid sound can be reduced. That is, the slight vibration of the face plate that generates the primary solid sound and the secondary solid sound is easily absorbed by the elastic deformation of the bent portion 5, and the emitted noise is remarkably reduced. In this way, the technology for reducing the solid sound by converting the sound pressure energy into the kinetic energy by the elastic deformation of the bent portion 5 in the interior plate mounting portion has never existed in the past. The effect that it can be reduced is a very advantageous effect that has not been seen so far.

  The face plate attachment material 1 is not limited to being directly fixed to the ceiling surface 2a, but can also be fixed via another member installed on the ceiling surface 2a. FIG. 3 is a perspective view showing a state in which the face plate attachment material 1 is fixed to the receiving material 9 installed for adjusting the unevenness on the ceiling surface 2a. By adopting such a configuration, even if the ceiling surface 2a is uneven, it is possible to attach the face plate mounting material 1 flatly by the effect of the receiving material 9, and there is a distance from the floor to the face plate. Therefore, the effect that the short period component of the primary solid sound can be reduced can also be expected. In addition, although the grooved steel can be used for the receiving material 9, not only this but various materials should be used if the unevenness of the ceiling surface 2a can be adjusted and a predetermined space can be provided. Can do.

  Further, suppressing the vibration of the face plate which is a direct sound source in the downstairs, that is, suppressing the sound pressure level (dB (C) value indicating sound energy) is the noise level (the amount of sound that a person feels by hearing in dB). In addition to reducing (A) value, there is also an effect that the reverberation time can be shortened particularly in a low frequency sound region. Such a phenomenon is said to be "the reverberation time decreases from low to mid-range even on a wall that vibrates plate with a glass plate (Masayuki Matsui, Acoustic Materials (above): Shokokusha)". I can understand that. Conventionally, porous materials such as glass wool, which have been used as the amount of sound absorbing material, are exclusively used for absorbing high frequency sound, and it has been difficult to absorb low frequency sound. However, in this invention, since the secondary solid sound called a low frequency sound among solid sounds can be reduced, the soundproofing technique which has not existed until now can be provided.

  Hereinafter, each component will be described in detail.

(Face plate mounting member)
First, the face plate mounting member 1 will be described with reference to FIGS. 2 and 4 to 6. As shown in FIG. 1, the face plate mounting member 1 has a substantially quadrilateral shape that is longer in the axial direction (arrow X) than in the width direction (arrow Y) in plan view. In addition, the face plate mounting member 1 has, as shown in FIG. 2, two locking surfaces 4 so that a single installation surface 3 is disposed in the center in a cross-sectional view and a step is formed on both sides of the installation surface 3. And a bent portion 5 is formed between the installation surface 3 and the locking surface 4. The installation surface 3, the locking surface 4, and the bent portion 5 can be processed as one piece from a single strip. Of course, they can be formed as separate bodies and integrated later by welding or the like. However, in that case, it is necessary to manufacture them so as to be elastic as a whole through the bent portion 5. The face plate mounting member 1 is preferably made of an elastic material (a material having strength and easily elastically deformed), and at least the bent portion 5 is preferably made of the elastic material.

1. Installation surface The installation surface 3 is for installing a face plate, and is formed as a flat surface as a whole. As described above, the installation surface 3 can be provided with a width groove portion 7a (FIG. 1) and a shaft groove portion 7b (FIG. 1) for preventing harmful local deformation, and to guide a driving nail for installing the face plate. It is also possible to provide a large number of fine holes 8 (FIG. 1) or fine convex and concave portions.

2. Locking surface The locking surface 4 is for fixing the face plate mounting member 1 to the ceiling surface 2 a, and is formed as a flat surface as a whole like the installation surface 3. As shown in FIG. 2, the locking surface 4 is provided at each of the both end portions in the width direction of the installation surface 3, and a step is provided from the installation surface 3 because the bent portion 5 is provided therebetween. Yes. Specifically, when the face plate mounting member 1 is placed so that the installation surface 3 is substantially horizontal and the upper surface, a height difference between the locking surface 4 and the installation surface 3 (a bent portion 5 is provided at this height difference). The installation surface 3 is in the upper stage and the locking surface 4 is in the lower stage. Further, the installation surface 3 and the locking surface 4 are arranged substantially in parallel so that the ceiling surface 2a and the face plate are arranged substantially in parallel.

  As shown in FIG. 2, a convex groove 10 can be provided on the locking surface 4. The convex groove 10 is provided for the purpose of increasing the section modulus and reducing the stress caused by the external force. In FIG. 2, two convex grooves 10 (four locations on both sides) are provided for one locking surface 4, but the number and shape of the installation locations can be arbitrarily designed. Moreover, as shown in FIG. 2, the edge part reinforcement can also be aimed at by providing the bending edge part 11 which reversed the edge part of the latching surface 4 about 180 degree | times.

3. Bending portion The bending portion 5 is provided between the installation surface 3 and the locking surface 4 and absorbs vibrations of the face plate, for example, by elastic deformation. As shown in FIG. 2, the bent portion 5 is continuously provided on both end sides in the width direction of the installation surface 3, and is further continuous with the locking surface 4. In other words, one end of the bent portion 5 is continuous with the installation surface 3, and the other end of the bent portion 5 is continuous with the locking surface 4.

  As shown in FIG. 2, the bent portion 5 is composed of a first folded portion 5a and a second folded portion 5b. The first folded portion 5a is provided at an end portion on the side continuous with the installation surface 3, and has a substantially semicircular shape in a sectional view. On the other hand, the 2nd folding | turning part 5b is provided in the edge part of the side continuous with the latching | locking surface 4, and is also exhibiting the substantially semicircle by sectional view.

  The first folded portion 5a and the second folded portion 5b are both semicircular in sectional view, but their bending directions are reversed, that is, the first folded portion 5a is on the inner side in the width direction of the installation surface 3. The second folded portion 5 b is a semicircle having a center on the outer side in the width direction of the installation surface 3. Hereinafter, for convenience, the shape of the first folded portion 5a as shown in FIG. 2 is referred to as an “outer curve”, and the shape of the second folded portion 5b is referred to as an “inner curve”.

  In FIG. 2, the axis of the installation surface 3 and the axis of the first folded portion 5a (the tangential direction of the circle) are substantially collinear, and the axis of the locking surface 4 and the axis of the second folded portion 5b (the tangent of the circle) Direction) is substantially the same straight line. Moreover, at the inflection point 5c, which is a point where the first folded part 5a and the second folded part 5b are connected (in other words, a point where the first folded part 5a changes to the second folded part 5b), the first folded part 5a. And the axis of the second folded portion 5b are substantially in the same straight line. However, the bent portion 5 constituting the face plate mounting member 1 of the present invention does not necessarily have such a strict shape, and the first folded portion 5a and the second folded portion 5b do not need to be semicircles. In order to be easily elastically deformed, it is only necessary to provide a first folded portion 5a that is folded inward (outer curve) and a second folded portion 5b that is folded outward (inner curve).

  The bent portion 5 is required to have a strength that does not break due to vibrations received from the outside, but also has a function of easily causing elastic deformation. Therefore, a slit (hereinafter referred to as “elongated hole 12”) can be provided in the bent portion 5. FIG. 4 is a cross-sectional view of the face plate mounting member 1 provided with the elongated holes 12 in the bent portion 5 in the width direction. As shown in this figure, the elongated hole 12 is provided in the vicinity of the inflection point 5c where the first folded portion 5a and the second folded portion 5b are connected, and has an elongated shape extending in the axial direction. The elongate hole 12 is provided in the vicinity of the inflection point 5c in this way because the deformation amount in the vicinity of the inflection point 5c is small compared to others and is the position where there is no problem in strength. In addition, the elongate hole 12 can also be formed in series from the edge part to the edge part in the axial direction of the faceplate attachment member 1, and can also be formed in multiple places intermittently.

  The first folded portion 5a and the second folded portion 5b that constitute the bent portion 5 have shapes that are folded in a sectional view, that is, a gap is formed inside by folding. In FIG. 4, the 1st clearance gap part 51 formed of the 1st folding | returning part 5a and the 2nd clearance gap part 52 formed of the 2nd folding | returning part 5b are shown. The larger the first gap portion 51 and the second gap portion 52 are, the smaller the curvature of each turn, and the bent portion 5 is more likely to be elastically deformed.

  On the other hand, however, the height of the bent portion 5 increases as the space of the gap portion increases, and the thickness of the face plate mounting member 1 also increases. Depending on the location where the face plate mounting member 1 is installed, it may be desired to reduce the thickness of the face plate mounting member 1. Therefore, the curvature of one of the first folded portion 5a or the second folded portion 5b is increased, that is, the space of either the first gap portion 51 or the second gap portion 52 is reduced, and the face plate The thickness of the attachment member 1 can be reduced. Even in this case, since one of the first gap 51 and the second gap 52 is equivalent to the gap shown in FIGS. 2 and 4, the function of easily causing elastic deformation is not greatly impaired.

  FIG. 5 is a cross-sectional view of the face plate attachment member 1 provided with a narrow gap 51s in the first folded portion 5a, cut in the width direction. As shown in this figure, the thickness t of the face plate mounting member 1 can be remarkably reduced by increasing the curvature of the first folded portion 5a and providing the narrow gap portion 51s in the first folded portion 5a. Of course, instead of providing the narrow gap portion 51s in the first folded portion 5a, a narrow gap portion may be provided in the second folded portion 5b.

  FIG. 6 is a cross-sectional view of the face plate mounting member 1 provided with the buffer member 13 in the narrow gap portion 51s in the first folded portion 5a in the width direction. As shown in this figure, the buffer member 13 can be provided in order to compensate that the elastic deformation performance of the bent portion 5 is somewhat impaired as a result of providing the narrow gap portion 51s in the first folded portion 5a. The buffer member 13 is desirably an elastic material such as rubber in order to exhibit sound absorbing performance, and for example, a rubber-like elastic sheet is suitable. The buffer member 13 may be sandwiched in the narrow gap portion 51s. When a narrow gap portion is provided in the second folded portion 5b, it is preferable to sandwich the narrow gap portion therein. Further, the buffer member 13 can be installed not only in the narrow gap portion 51 s but also in the first gap portion 51 and the second folded portion 5 b shown in FIGS. 2 and 4. As described above, when the buffer member 13 is provided on the face plate mounting member 1, an effect that surging (a kind of noise generated during resonance) can be prevented can be expected.

(Interior structure)
Below, based on FIGS. 7-10, the interior structure using the faceplate attachment member 1 is demonstrated. FIG. 7 is a cross-sectional view showing the interior structure formed on the ceiling 2. As shown in this figure, the interior structure of the present invention is composed of the above-described face plate mounting member 1 and face plate 14 of the present invention.

  Usually, a large number of face plate mounting members 1 are installed on the ceiling 2, and these face plate mounting members 1 are also arranged substantially in parallel, and in FIG. Further, in this figure, the face plate mounting member 1 has two locking surfaces 4 in contact with the ceiling surface 2a and is fixed by screws 15, but is not limited thereto, and can be fixed by a conventionally known fixing means. Is as described above.

  Usually, a large number of face plate mounting members 1 are installed on the ceiling 2, and these face plate mounting members 1 are arranged substantially in parallel, and in FIG. Further, in this figure, the face plate mounting member 1 has two locking surfaces 4 in contact with the ceiling surface 2a and is fixed by screws 15, but is not limited thereto, and can be fixed by a conventionally known fixing means. Is as described above.

  In FIG. 7, the face plate mounting member 1 is arranged so that the axial direction of the face plate mounting member 1 is oriented in a direction perpendicular to the paper surface (depth direction), but the arrangement direction of the face plate mounting member 1 is not particularly limited. 7, the face plate mounting member 1 can be arranged so that the axial direction of the face plate mounting member 1 is directed in the left-right direction on the paper surface. Usually, the face plate 14 is also a long member that is long in the axial direction, and in this case, the face plate mounting member 1 is arranged so that the axial direction of the face plate 14 and the longitudinal direction of the face plate 14 are orthogonal to each other. For example, in the case of FIG. 7, the axial direction of the face plate mounting member 1 is arranged in a direction perpendicular to the paper surface, and the longitudinal direction of the face plate 14 is arranged in the left-right direction on the paper surface. Of course, when the width | variety of the faceplate 14 is wide, or when the arrangement | positioning space | interval of the faceplate attachment member 1 is short, it can also arrange | position so that the axial direction of the faceplate attachment member 1 and the longitudinal direction of the faceplate 14 may be parallel. The face plate 14 is installed on the installation surface 3 of the face plate mounting member 1 (the lower surface of the face plate mounting member 1 in FIG. 7) by a driving nail or the like.

  In FIG. 7, a face plate 17 is attached to the indoor side of the wall 16, and a peripheral edge 18 is provided at a joint portion with the face plate 14 attached to the ceiling 2. In this way, it is preferable from the viewpoint of acoustics and design that the surrounding edge 18 is used.

  FIG. 8 is a cross-sectional view showing the interior structure formed on the wall 16. As shown in this figure, the interior structure of the present invention can be formed not only on the ceiling but also on various structures including a wall 16. When the interior structure is formed on the wall 16, the face plate mounting member 1 is arranged in parallel in the horizontal direction or the vertical direction, the two locking surfaces 4 are brought into contact with the surface of the wall 16, and are fixed by screws 15 or the like. Then, the face plate 17 is arranged in the vertical direction or the horizontal direction, is brought into contact with the installation surface 3 of the face plate attachment member 1, and is installed on the face plate attachment member 1 with a driving nail or the like. Also in this case, it is desirable to install a peripheral edge 18 at the joint between the face plate 14 and the face plate 17 attached to the ceiling 2.

  FIG. 9 is a cross-sectional view showing the interior structure in the wooden wall assembling method. The interior structure of the present invention can also be implemented in a wooden building by a wooden wall assembling method (so-called 2 × 4 method). Even if it is a wooden building by a wooden wall construction method, the structure of the faceplate attachment member 1 is as having demonstrated based on FIG.2 and FIG.4-FIG.6, and the arrangement method of the faceplate attachment member 1, a fixing method, or a faceplate The arrangement method and installation method 14 are the same as those described with reference to FIGS. Further, it is also desirable that the peripheral edge 18 is desirably installed at the joint portion between the face plate 14 and the face plate 17 attached to the ceiling 2.

  What is characteristic of the wooden wall assembling method is that it is desirable to fix the locking surface 4 to the beam material 19 unique to this method. Thereby, the faceplate attaching member 1 can be firmly fixed to the ceiling surface 2a. In addition, when it arrange | positions so that the axial direction of the beam material 19 and the axial direction of the faceplate attachment member 1 may orthogonally cross, it fixes in the location where the beam material 19 and the latching surface 4 cross | intersect, and it is shown in FIG. When the axial direction of 19 and the axial direction of the face plate mounting member 1 are arranged so as to be substantially parallel, either one of the two locking surfaces 4 on the left and right sides is arranged directly below the beam member 19. It is good to fix.

  FIG. 10 is a cross-sectional view showing the interior structure in the wooden wall assembling method when the receiving material 9 is suspended by the hanging tree 20. As shown in this figure, instead of the ceiling surface 2a, the face plate mounting member 1 can be fixed to a receiving material 9 suspended by a hanging tree 20. In this case, the unevenness of the ceiling surface 2a can be adjusted, and since the distance from the ceiling surface 2a to the face plate 14 is large, an effect that primary solid sound can be reduced can be expected. The receiving material 9 may be suspended by a hanging tree, and a grooved steel can be used as the receiving material 9, but not limited to this, various materials can be used as described above. .

  The face plate mounting member and the interior structure of the present invention can be used in a multi-storey building such as a school building or a warehouse, in addition to being usable in an apartment house such as a condominium or an office building. This is particularly effective for buildings where noise caused by solid sound is extremely disturbing, such as broadcasting facilities, movie theaters, and concert halls.
