  The present invention relates to a sound insulation panel that can be used as a soundproof room, a soundproof capsule, a wall or ceiling of a house, or a partition (partition), and a sound insulation room formed using the same.

  In recent years, there are an increasing number of households enjoying full-scale home theater in the home and playing piano and other musical instruments as hobbies and lessons, which is accompanied by blocking outdoor noise and conversely indoor sound. Various sound insulation techniques such as panels and partition walls having sound insulation properties have been proposed in order to prevent the leakage of water. And such a sound insulation panel is composed of a single piece such as a plywood that is a plate material, an aluminum plate that is a gypsum board, a cement plate or a perforated plate, or a plurality of panel layers. There is something configured. And regarding this sound insulation technique, patent documents 1 to 3 have been proposed previously.

  In Patent Document 1 (Japanese Utility Model Laid-Open No. 61-36009), a plurality of gypsum lath boards in which a large number of embossed recesses are formed only on one side are bonded to each other so that the embossed recesses face inward with any gypsum lath board After being laminated, the drums are nailed to the surface of the underlying structure at predetermined intervals to form a drum-structured wall, the diffuse reflection of the transmitted sound is lost due to the embossed recesses, and the individual natural vibration of the plaster lath board between each nail We propose a sound insulation wall that forms a sound insulation structure by damping.

Japanese Utility Model Publication No. 61-36009 Japanese Utility Model Publication No. 5-6082 JP-A-9-72016 Japanese Patent Laid-Open No. 11-287004

  As described above, various types of sound insulation panels have been proposed in the past, and it has also been proposed to partition and form a soundproof room in a building.

  However, the sound insulation panels proposed so far are made of gypsum board with or without a large number of holes or glass wool, so that the sound insulation with a transmission loss of 50 dB. It was difficult to ensure performance.

  Accordingly, the first object of the present invention is to provide a sound insulation panel and a sound insulation room which are sound insulation panels used in combination, and which are effective against both high frequency and low frequency noises.

  Moreover, the sound insulation panel provided conventionally has already been subjected to a specific decoration such that the outer panel is a decorative panel, and the degree of freedom in the owner is not sufficient.

  Accordingly, the present invention provides a sound insulation panel and a sound insulation chamber that can be decorated on the surface in the same manner as the interior decoration at the time of construction, and can further exhibit sound absorbing performance as necessary. It is an issue.

  Furthermore, when a sound insulation room is constructed using a conventional sound insulation panel, various techniques for improving the ease of connection by combining the panels have been proposed, but the combination is easy but sufficient in the connection portion. A sound insulation room with sound insulation and a sound insulation panel for constructing the sound insulation room have not yet been provided.

  Therefore, in the present invention, it is a third object to provide a sound insulation chamber capable of reliably performing sound insulation at the connecting portion and a sound insulation panel for forming the sound insulation panel while the sound insulation panels can be easily combined. .

  In order to solve at least one of the above problems, in the present invention, a sound insulation board member formed by forming a plurality of dents on at least one surface of a board formed of an inorganic material in a plate shape is provided at a certain interval. The present invention has been completed by finding that the sound insulation effect can be enhanced by arranging the dent-formed surfaces so as to face each other.

  That is, in order to solve any of the above-described problems, in the present invention, a sound insulation board member formed by forming a plurality of dents on at least one surface of a board formed of an inorganic material in a plate shape is spaced at a certain interval. And a filling member selected from a heat insulating material, a sound insulating material, and a sound absorbing material is disposed between and at least one of the outer sides of the sound insulating board members disposed opposite to each other. Provided is a sound insulation panel in which a base member is arranged on the outermost side, and these sound insulation board members, a filling member and a base member are laminated and integrated.

  The sound insulation board member is formed by forming a plurality of depressions on one side or both sides of a board made of an inorganic material such as a plaster board or a board made of concrete. The dents formed on the board made of the inorganic material are regularly formed at regular intervals, and the dents can be unevenly distributed, for example, in any of the height directions of the board.

In addition to the circular opening shape, the recess can be formed in a triangle, square, rectangle, or other shape. The opening area is preferably 0.5 cm ² or more and 10 cm ² or less, particularly 1 cm. It is desirable to be ^{2 to 3} cm ² . This dent functions to diffuse low-frequency sound. If the opening area is less than 0.5 cm ² , the low-frequency sound is still not sufficient for supplementation, and the opening area exceeds 10 cm ^2. This is because the sound diffusion effect due to the dent cannot be sufficiently obtained. The depth of the recess is preferably 1 mm or more and 6 mm or less, particularly 2 mm or more and less than 4 mm when the thickness of the board made of inorganic material to be used is 9.5 mm. Is desirable. If it is less than 1 mm, it cannot be said that the diffusion at the time of reflection of the low frequency sound is still sufficient, and if it exceeds 6 mm, the thickness of the board in the recessed portion is not sufficient, and sound leaks from the bottom of the dent. This is because there is a fear. Therefore, it is preferable that the depth of the recess is about 1/3 of the thickness of the board made of the inorganic material to be used. The distance between the recesses is preferably 4 cm to 8 cm.

  Further, it is desirable that the shape of the dent is recessed in a shape constricted toward the bottom, such as a reverse truncated cone shape or a hemispherical shape. This is because sound can be effectively reflected or diffused by making the side surface of the groove an inclined surface or a curved surface.

  Such a dent may be formed by pressing from the surface during the production of the board made of the inorganic material to be used. In the case of a relatively shallow dent, it may be formed by cutting with a drill or other cutting machine. it can.

  The sound insulation board member formed with the dents is arranged with the surfaces on which the dents are formed facing each other and at a predetermined interval. By making the surfaces where the dents are formed face each other, the sound wave that has passed through the sound insulation board is diffused in the dent portions, and can be further diffused by hitting the dent portions of the opposing sound insulation board. In other words, the sound insulating board has a surface in which dents are formed so as to face each other, and a space for diffusing sound waves is secured by keeping a certain distance therebetween. In addition, since a filling member selected from a heat insulating material, a sound insulating material, and a sound absorbing material is disposed in this space, resonance between sound insulating boards is prevented, and sound waves that are diffused between sound insulating boards are attenuated, A heat insulating effect can be exhibited. If the sound insulation board is placed in contact with the surface where the dent is formed, the vibration of one sound insulation board (vibration due to the sound wave) simply propagates to the other sound insulation board, so a sufficient sound insulation effect cannot be obtained. . Therefore, by disposing the filling member between the sound insulation boards, it is possible to prevent the propagation of sound waves (vibration) between the sound insulation boards by securing a gap between them.

  From the standpoint of sound insulation, the gap between the sound insulation boards is preferably as large as possible. On the other hand, there is a high demand for forming the sound insulation panel to be thin in order to secure a wide indoor space. Therefore, in the sound insulation panel according to the present invention, the gap between the sound insulation boards arranged to face each other is desirably 5 mm or more and less than 20 mm, and particularly desirably 5 mm or more and less than 15 mm. If it is less than 5 mm, the sound insulation boards arranged opposite to each other may be in contact with each other due to distortion or deformation of the sound insulation board, and 5 mm or more is necessary even in consideration of the diffusion of sound waves.

  As the heat insulating material that can be disposed between the above sound insulation boards, the heat conductivity coefficient is low, and if necessary, resin-based heat insulating materials such as phenol foam, urethane foam, polystyrene foam, etc., and inorganic heat insulating materials such as glass wool and rock wool. A natural heat insulating material such as a material or cellulose fiber, wool heat insulating material, carbonized foam cork and the like can be used.

  In addition, materials that do not easily propagate the wavelength of sound waves are used as sound insulation materials. In addition to glass wool and rock wool, metals such as lead, iron, copper, and brass, concrete, cement, stone powder, rock powder, gypsum, and calcium carbonate In addition, a sheet or plate formed using calcium silicate, glass, rubber or the like can be used.

  The sound absorbing material is a material that absorbs sound by heat loss due to heat exchange between the fibers and between the particles, vibration resistance due to viscous resistance, or energy loss due to vibration of the material itself due to propagation, such as glass wool, rock wool, etc. Plate-like sound-absorbing materials, metallic sound-absorbing materials such as aluminum, ceramic-based porous sound-absorbing materials, concrete materials, plywood, gypsum board, particle board, and other perforated plates with many holes formed in them be able to.

  As the filling member disposed between the sound insulation boards, a material made of glass wool having all of the properties of sound insulation, sound absorption, and heat insulation is desirable, but particularly when filling the heat insulation and sound absorption, rubber or the like It is also possible to arrange a plate-like member made of the above resin material and having sound absorption and heat insulation properties.

  In the sound insulation panel according to the present invention, a filling member selected from a heat insulating material, a sound insulation material, and a sound absorption material is provided between the sound insulation boards arranged opposite to each other and at least one of the sound insulation boards. That is, the said filling member can be provided in the outer side of the one or both of the sound-insulating boards arranged facing each other. Moreover, as the filling member, in addition to any one of a heat insulating material, a sound insulating material, and a sound absorbing material, two or more selected from a heat insulating material, a sound insulating material, and a sound absorbing material can be laminated. Further, a sound absorbing material can be provided outside one of the sound insulating boards, and a heat insulating material can be provided outside the other sound insulating board. These filling members are desirably provided so as to cover the outer surface of the sound insulation board facing each other, and can be arranged in the form of foam, fiber, plate, sheet or the like.

  By disposing such a filling member on the outside of the sound insulation board, it is possible to achieve a heat insulation effect in the region partitioned by the sound insulation panel in the heat insulation material, and in the sound insulation material, a sound wave having a relatively high frequency can be obtained. It can be effectively absorbed and attenuated, and the sound absorbing panel can effectively absorb the sound waves reflected or transmitted by the sound insulating board, such as glass wool, etc. It is desirable to use a material having a composite function regarding heat insulation, sound insulation and sound absorption.

  And in the sound-insulating panel which concerns on this invention, a base member is arrange | positioned as outer-shell material on the outermost side. As the base member, a general base material used for interiors in a building, such as a panel, a plywood board, a plaster board, or the like can be used. In particular, in the sound insulation panel according to the present invention, since the foundation member for building is used as the outermost member, the wallpaper, cloth, etc. are provided outside the foundation material in the same manner as general residential buildings. At the time of construction, such as pasting, applying plaster, or applying paint, the surface decoration can be applied in the same manner as the interior decoration. As a result, a client who builds a building or a structure using the sound insulation panel can perform free decoration, thereby satisfying various requests of the client.

  The sound insulation board member, the filling member, and the base member are laminated and integrated in the order described above to constitute a sound insulation panel. When stacking and integrating such members, it is desirable to hold each member with a side member that forms a side surface along the thickness direction of the sound insulation panel. This side member can be formed of natural resin such as wood, and can be formed of a synthetic resin blended with a rubber component, and can be formed of other materials such as gypsum, concrete, and metal. . The sound insulation board member and the base member can be fixed to the side member by a nail, an adhesive, an occlusion or a fitting structure, and the filling member can be sandwiched between the sound insulation board and the base member. .

  In the sound insulation panel according to the present invention, it is preferable that the side member is provided with a support portion that holds at least one of the sound insulation board members, and at least one of the sound insulation board members is supported by the support portion. . That is, when the sound insulation panel is manufactured, after the base member is fixed to the side member, the filling member and the sound insulation board are laminated on the base member, and the filling member is made of a compressible member such as glass wool. For this reason, it is difficult to determine the positioning of the sound insulation board without taking any measures. Therefore, from the viewpoint of ease of manufacture, it is desirable to form a support portion for supporting at least one of the sound insulation board members on the side member. Such a support part is formed in a step shape along the length direction of the side member, or a groove for accommodating the side edge portion of the sound insulation board along the length direction of the side member, or any part. This can be realized by forming a projection to hold the sound insulation board.

  Such a sound insulation panel is preferably formed in a plate shape having a constant thickness as a whole, and its side surfaces are closed by side members, and the upper and lower surfaces are also closed.

  In the sound insulation panel according to the present invention, in consideration of workability when joining together and sound insulation at the joining portion, at least one of the base members is formed in a plate shape and exists in the width direction. It is desirable to form, on at least one of the side sides, a joining portion that protrudes from the side member that constitutes the side surface along the thickness direction of the laminated sound insulating board member, the filling member, and the base member. Such a joining portion protrudes from the side member constituting the side surface in the thickness direction in which the sound insulation board member, the filling member, and the base member are laminated, and is overlapped with the adjacent sound insulation panel at the time of joining. Together, both can be integrated. In addition, if a sealing layer made of rubber or a resin material is formed on the back surface of the joint portion, when the sound insulation panels are joined together, the sealing performance at the joint portion is improved and the sound insulation performance is improved. Can do.

  In the present invention, in order to solve at least one of the above-described problems, a sound insulation board member formed by forming a plurality of recesses on at least one surface of a board formed in a plate shape using an inorganic material is fixed. Arranged in such a manner that the surfaces formed with recesses are opposed to each other, and between the sound insulation board members arranged opposite to each other, a filling member selected from a heat insulating material, a sound insulation material, and a sound absorbing material is arranged, and arranged opposite to each other. The side edge of the sound insulation board member provides a sound insulation panel supported and fixed by a side member provided with a support portion for holding at least one of the sound insulation board members.

  In such a sound insulation panel, there is a sound insulation panel that is thin and can be easily installed in any place while ensuring sufficient sound insulation by laminating sound insulation boards and fixing them with side members to make a module. Realize. However, also in such a sound insulation panel, it is desirable to arrange a filling member selected from a heat insulating material, a sound insulation material, and a sound absorbing material on the outside of the sound insulation board disposed oppositely.

  The sound insulation panel according to the present invention can be used as a material for forming a sound insulation room shown below, and can be used not only at the time of building a building but also at renovation of a built house. In particular, when renovating, it can be used as a flooring material, a wall material, or a ceiling material in a room or hallway that needs to be sound-insulated due to changes in the living environment.

  And in this invention, in order to solve at least any one of the said subject, the sound insulation room formed using the said sound insulation panel, and the construction method of the said sound insulation room are provided.

  That is, the sound insulation room according to the present invention is a sound insulation room assembled and installed in a building and having at least a wall surface and a ceiling surface, and at least the wall surface is formed of the sound insulation panel according to the present invention. provide.

  In such a sound insulation room, since the sound insulation panel according to the present invention is used, sufficient sound insulation performance can be secured, and since it is installed in a building, it is inexpensive without performing special waterproofing treatment. Can be built. Moreover, since the sound insulation panel according to the present invention is modularized, it is easy to transport and assemble, and a sound insulation chamber that is easy to manufacture is provided.

  The sound insulation room forming method according to the present invention is a method for forming a sound insulation room assembled and installed in a building and having at least a wall surface and a ceiling surface, and at least the wall surface is connected to the sound insulation panel according to the present invention. It comprises a panel connecting step to be formed and an interior construction step for constructing interior material on the surface of the base member constituting the sound insulation panel.

  In such a sound insulation room forming method, since the sound insulation panel according to the present invention described above is used, the sound insulation panels can be easily and reliably joined together, and sound insulation properties at the joined portions can be secured. Can do.

  And since the surface and the back surface in the sound insulation panel according to the present invention are both formed of the base material, the interior material for applying the interior material to the surface of the base member constituting the sound insulation panel is provided separately from the panel connection step. A construction step can be performed, and thereby, interior decoration suitable for the taste of the owner can be performed.

  Since the sound insulation panel of the present invention has a structure in which the sound insulation board and the filling member are combined, it can be used in connection and combination, and is effective for both high frequency and low frequency noises. A sound insulation panel is provided.

  In addition, since the outermost surface of the sound insulation panel according to the present invention is composed of a base member, the surface decoration can be applied in the same manner as the interior decoration at the time of construction, and if necessary, the sound absorbing performance A sound insulation panel that can be used to achieve this is realized.

Schematic showing the attenuation of sound waves in a sound insulation panel An exploded view of a sound insulation room formed using sound insulation panels

  Hereinafter, one embodiment of a sound insulation panel 90 and a sound insulation chamber according to the present invention will be described with reference to the drawings.

  FIG. 1 is an exploded view of the sound insulation panel 90 according to the present embodiment, FIG. 2 is a schematic horizontal sectional view showing a laminated state of the sound insulation panel 90, and FIG. 3 shows a joined portion of the sound insulation panel 90. FIGS. 4 and 5 are main part horizontal sectional views showing a sound insulation panel 90 according to another embodiment, and FIG. 6 is a schematic diagram showing attenuation of sound waves in the sound insulation panel 90. 7 is an exploded view of a sound insulation chamber formed by using the sound insulation panel 90.

  In the sound insulation panel 90 shown in this embodiment, the sound insulation board 10, the second filling member 30, and the base member 40 are laminated in this order to form a structural unit 70, and this structural unit 70 is formed as the first filling member. They are arranged so as to be opposed to each other with 20 as the center. And in the sound insulation board 10 opposingly arranged through this 1st filling member 20, the several dent 12 is formed in the opposing surface.

  That is, the sound insulation panel 90 is configured such that the sound insulation board 10 formed by forming the recess 12 on one surface of the gypsum board is opposed so that the surface of the recess 12 faces each other with a certain interval. The first filling member 20 that exhibits at least one of the functions of sound insulation, heat insulation, and sound absorption is disposed between the sound insulation boards 10. Further, on the outside of each sound insulation board 10, a second filling member 30 formed of glass wool in a plate shape is disposed so as to cover the sound insulation board 10. On the outside of the second filling member 30, a base member 40 formed in a rectangular plate shape using a veneer plate or the like is stacked, and held between the base member 40 and the sound insulation board 10 with the filling member interposed therebetween. Yes.

  The laminated structure 80 composed of the first member and the structural units arranged opposite to each other with the first member as the center is closed by the side member 50. That is, the side member 50 is formed in a plate shape using an inorganic material such as natural resin, synthetic resin, or gypsum, and the length thereof is the same as the length of the sound insulation board 10 and the base member 40. The width is formed to be the same as the thickness of the laminated structure in which the sound insulating board 10, the filling member, the base member 40, and the like are laminated. In particular, in this embodiment, the side surface member 50 is formed by forming a horizontal cross-sectional shape in an L shape, and a portion 52 stepped in the “L” shape holds one of the sound insulation boards 10. is doing.

  FIG. 2 is a schematic horizontal cross-sectional view of the sound insulation panel 90 shown in FIG. 1. In this embodiment, a first filling member 20 having a thickness of about 12 mm in which glass wool is molded into a plate shape is disposed at the center. On both sides, the sound insulation boards 10 having a thickness of about 9.5 mm are disposed opposite to each other so that the surface of the recess 12 faces the first filling member 20 and abuts against the first filling member 20. Therefore, the sound insulation boards 10 are separated from each other by about 12 mm by the first filling member 20, and the gap is maintained. Furthermore, since the sound insulation board 10 is fixed to the side member 50, rattling or the like can be reliably prevented. In FIG. 2, reference numeral 60 denotes a sound insulation structural unit including the first filling member 20 and the sound insulation board 10 sandwiched with the first filling member.

  And on the outer side of this sound insulation board 10, the 2nd filling member 30 formed by shape | molding glass wool in plate shape is arrange | positioned. The second filling member 30 has a second filling member 30 formed to have a thickness of about 25 mm on the outside of one of the sound insulation boards 10, and a thickness of about 2 mm on the outside of the other sound insulation board 10. The 2nd filling member 30 formed in about 10 mm is arrange | positioned. By providing the second filling member 30, the sound insulation board 10 can be suppressed, and sound insulation properties, heat insulation properties, and sound absorption properties can be ensured.

  A base member 40 made of a veneer plate having a thickness of about 3 mm is disposed outside the second filling member 30. The foundation member 40 is located on the surface of the sound insulation panel 90, and interior work such as wallpaper, cloth, and plaster is applied on the foundation member 40 at the time of construction. It is also possible to use, for example, a sound absorbing plate formed with a plurality of openings as any or all of the base members 40, and in this case, the interior applied on the base member 40 If a cloth cloth or the like is used, there is no possibility of impeding the function of the sound absorbing plate. In particular, in this embodiment, the base member 40 is fixed while being shifted to one of the width directions. As a result, one side of the shifted base member 40 forms a joining portion 42 that protrudes from the side member 50, and this is used when joining the sound insulation panels 90. In addition, a sealing layer made of rubber or a resin material is provided on the back surface of the joining portion 42, so that airtightness (that is, sealing property) at the joining portion 42 of the sound insulation panel 90 can be enhanced.

  Thus, the sound insulation panel 90 according to the present embodiment formed by laminating the members as described above has a thickness of about 72 mm as a whole, and thus can be sufficiently independent even when the room is partitioned. Can be secured. However, the thickness of the sound insulation panel 90 can be changed as appropriate. Specifically, the thickness of the entire sound insulation panel 90 can be changed by changing the thickness of the first and / or second emphasis member. Further, the sound insulation panel 90 in this embodiment is formed to have a height of about 200 mm and a width of 500 mm, thereby enhancing versatility when used as a sound insulation room or a partition.

  FIG. 3 is an enlarged cross-sectional view of a main part showing a connection state of the sound insulation panel 90 shown in FIGS. 1 and 2. As described above, in the sound insulation panel 90 according to the present embodiment, one of the base members 40 is shifted in the width direction, thereby causing one side edge of the base member 40 to protrude from the side member 50. This is the joining unit 42. In the present embodiment, since the joint portion 42 is provided, as shown in FIG. 3, when the sound insulation panel 90 is provided in series in the lateral direction, the joint portion 42 in the one sound insulation panel 90 is provided. Can be put on the side member 50 of the other sound insulation panel 90, and the covered part can be connected with a nail or a screw, or can be bonded with an adhesive. As a result, the two adjacent sound insulation panels 90 are securely coupled to each other and have a certain thickness, so that they can be used as a partition wall that can stand on its own. In addition, it is also desirable to provide a sealing layer formed using rubber or other resin on the inner surface of the joint portion 42, that is, the surface overlapping the other sound insulation panel 90.

  4 and 5 show horizontal cross-sectional views of the main part of sound insulation panels 90 ′ and 90 ″ according to another embodiment. First, in the embodiment shown in FIG. 4, the side member 50 ′ has two stages. The thickness is changed to form two step portions 52, and the sound insulation boards 10 arranged to face each other are supported on the step portions 52. In particular, FIG. As shown in FIG. 2, the sound insulation board 10 can be reliably fixed by supporting the side edge portion of each sound insulation board 10 with the stepped portion 52 formed on the inner surface of the side member 50 ′. Thus, it is possible to reliably prevent the sound insulation board 10 from vibrating due to the sound wave, and the sound insulation board 10 can be fixed on the stepped portion or by using a nail or an adhesive.

  5 shows a sound insulation panel 90 ″ in which the base member 40 that forms the joining portion 42 is the base member 40 that exists on the side member 50 on the side where the thickness is formed thin. In the embodiment shown in FIG. 4, the joining portion 42 is formed by shifting the base portion existing in the thicker side of the side member 50, but the sound insulation panel 90 ″ shown in FIG. The joining portion 42 is formed by shifting the base member 40 existing on the side where the thickness of the member 50 is formed thin. The joint portion 42 can also be formed on both of the base members 40. For example, the joint portion 42 is formed at an opposing position in the sound insulation panel 90, and the joint portion 42 is joined in a positional relationship on the diagonal line of the sound insulation panel 90. A mating portion 42 can be formed.

  Next, the mechanism of sound insulation in the sound insulation board 10 will be described based on a schematic diagram showing attenuation of sound waves in the sound insulation panel 90 shown in FIG. In particular, FIG. 6A shows a state in which the dents 12 formed on the sound insulation board 10 are arranged facing each other, and FIG. 6B shows the dents 12 formed on the sound insulation board 10 arranged alternately. Shows the state. In which state the sound insulation board 10 is arranged is arbitrary. As shown in FIGS. 6 (A) and 6 (B), when the sound insulation board 10 is disposed facing each other with the recesses 12 facing each other, the sound wave that has entered from one sound insulation board 10 is indicated by an arrow in the drawing. In this case, most high-frequency sound waves are shielded by the sound insulation board 10 and absorbed by the second filling member 30. On the other hand, it is conceivable that high-frequency sound waves pass through the sound insulation board 10, but this is diffused between the sound insulation boards 10 by the recesses 12 existing inside the sound insulation board 10. Here, although it hits the sound insulation board 10 which opposes by progress of the diffused low frequency sound wave, since the recess 12 is formed also in the sound insulation board 10 which opposes, it is further spread | diffused by the said recess 12. FIG. In this sound wave diffusion, there is no sound wave that is attenuated by the plate-like glass wool disposed between the sound insulation boards 10 and passes through the sound insulation board 10 opposite to the sound wave entry direction. Thereby, the sound insulation panel 90 which can perform sound insulation in the frequency of a high sound and a low sound is implement | achieved.

  FIG. 7 is an exploded view showing a state in which a sound insulation room is configured using the sound insulation panel 90. As shown in this figure, the sound insulation room shown in the present embodiment has a wall surface, a floor surface, and a ceiling surface, The sound insulation panel 90 described above is used. At that time, the connection of the sound insulation panels 90 arranged in parallel can be reliably performed by the presence of the joining portion 42 as shown in FIG. 3, and sound leakage from the portion can also be prevented. it can.

  And, as shown in this figure, the sound insulation chamber formed using the sound insulation panel 90 has the base member 40 exposed to the inside and outside of the room in the assembled state. it can. Although it seems that the work process is complicated at first glance regarding the point of performing this interior later, it is desirable from the viewpoint of design because the interior can be arbitrarily specified according to the client's preference. Rather, when the sound insulation panel 90 to which the decorative panel is applied in advance is used, the owner's free interior is obstructed or another interior must be performed again, and the work becomes complicated on the contrary. End up.

  Therefore, as shown also in this embodiment, the fact that the outer surface of the sound insulation panel 90 is formed using the base member 40 is important in satisfying the desire of the owner.

  In order to improve the sealing performance at the joint between the sound insulation panels 90, the joint portion 42 is filled with a sealing material, or a metal tape such as aluminum, a resin tape containing rubber, etc. It is also desirable to do.
