Description

[Technical Field]

[0001] The present invention relates to a face material support structure. [Background technology]

[0002] In a typical building such as a house, the interior space is divided into multiple rooms by partition walls. In the partition wall structure, the edges along the joints of multiple horizontally arranged face panels are supported by support members such as studs that extend vertically. Patent Document 1 discloses a movable partition device as a partition wall structure of this kind.

[0003] The movable partition device disclosed in Patent Document 1 comprises a plurality of panels as face materials, studs as support members for supporting the panels, an elastic body sandwiched between the panels and the studs, and a joint plate that is arranged to press the elastic body against the studs and conceals the joints between the plurality of panels.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 50-119418 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the technology disclosed in Patent Document 1, multiple face materials are supported separately by the support member, allowing relative movement between the multiple face materials, which may result in unevenness on the surface made up of the multiple face materials.If unevenness occurs when a cross material is attached to a surface made up of multiple face materials, there is a risk that the cross material will break.

[0006] An object of the present invention is to provide a panel support structure that can improve sound insulation performance and prevent unevenness from occurring on a surface made up of multiple panel materials. [Means for solving the problem]

[0007] A panel support structure according to a first aspect of the present invention comprises first and second panel members aligned in a direction perpendicular to a predetermined direction to form a joint extending in the predetermined direction, support members extending in the predetermined direction along the joint and supporting edges of the first and second panel members along the joint, elastic members having a lower elastic modulus than the first, second, and support members provided between the edges of the first and second panel members and the support members to suppress vibration transmission between the first and second panel members and the support members, and connecting means for connecting the edges of the first and second panel members to each other so as to restrict relative movement of the edges of the first and second panel members in a plane-perpendicular direction perpendicular to the predetermined direction and the orthogonal direction. The connecting means are located closer to the support member than the faces of the first and second panel members facing away from the support member.

[0008] According to the first aspect, an elastic member is provided between the edge portions of the first and second face materials and the support member. This allows the elastic member to suppress vibration transmission between the first and second face materials and the support member, thereby improving sound insulation performance. On the other hand, if the elastic member allows relative movement of the edge portions of the first and second face materials in a direction perpendicular to the surface, there is a risk of unevenness occurring on the surface formed by the first and second face materials. Therefore, the edges of the first and second face materials are connected to each other by a connecting means. This restricts relative movement of the edges of the first and second face materials, thereby preventing unevenness from occurring on the surface formed by the first and second face materials. Therefore, even when the cloth material is attached to the surface formed by the first and second face materials, breakage of the cloth material can be prevented. Furthermore, because the connecting means is disposed closer to the support member than the first surfaces of the first and second face materials that face away from the support member, the connecting means is restricted from protruding from the first surface formed by the first and second face materials. This makes it possible to prevent unevenness caused by the connecting means in the cross material attached to the first surface formed by the first and second face materials, while also preventing breakage of the cross material.

[0009] The second aspect of the panel support structure is the panel support structure of the first aspect, wherein the connecting means includes a connecting plate extending from the edge of the first panel to the edge of the second panel and fixed to the first panel and the second panel, and the elastic member is sandwiched between the connecting plate and the support member.

[0010] According to the second aspect, the connecting plate connects the edges of the double-sided materials to each other on the surfaces of the first and second face materials that face the support member, and can sandwich the elastic member between itself and the support member. Furthermore, because the connecting plate is interposed between the first and second face materials and the elastic member, the rigidity of the connecting plate itself can be effectively utilized to restrict relative movement of the edges of the first and second face materials, unlike when the first and second face materials are in direct contact with the elastic member.

[0011] The third aspect of the panel support structure is the panel support structure of the second aspect, wherein the connecting plate has a contact area that contacts the elastic member and a fixed area that extends from the contact area to an area that is away from the elastic member in the specified direction or the orthogonal direction, and the edges of the first panel and the second panel each overlap the support member when viewed in the direction perpendicular to the surface and are fixed only to the fixed area.

[0012] According to the third aspect, the connecting plate contacts the elastic member in the contact region, and the edges of the first and second face materials are fixed in the fixed region. That is, the connecting plate connects the edges of the first and second face materials to each other in the fixed region, and sandwiches the elastic member between the connecting plate and the support member in the contact region. This allows the connecting plate to connect the first and second face materials without affecting the elastic member.

[0013] The fourth aspect of the panel support structure is a panel support structure of the second or third aspect, in which the connecting plate has a protrusion that is inserted into the joint, and the protrusion is located on the support member side within the joint relative to the faces of the first panel and the second panel that face away from the support member side.

[0014] According to a fourth aspect, when the connecting plate is inserted into the joint between the first and second face members, the protruding portion is positioned closer to the support member than the first faces of the first and second face members that face away from the support member. In this case, the protruding portion is contained within the joint and is restricted from protruding from the first face formed by the first and second face members.

[0015] A fifth aspect of the panel support structure is the panel support structure of any of the second to fourth aspects, wherein the connecting plate is provided over the entire length of the first panel and the second panel in the predetermined direction.

[0016] According to the fifth aspect, the connecting plate connects the edges of the first and second face materials to each other over the entire length of the first and second face materials in the predetermined direction in which the joints extend, thereby preventing unevenness from occurring on the surface formed by the first and second face materials over the entire length of the first and second face materials.

[0017] A panel material support structure according to a sixth aspect is the panel material support structure of any one of the second to fifth aspects, wherein the elastic member and the connecting plate are configured as a single member.

[0018] According to the sixth aspect, the elastic member and the connecting plate are configured as one member, which simplifies the construction of the surface material support structure. [Effects of the Invention]

[0019] As described above, according to the present invention, it is possible to provide a panel support structure that can improve sound insulation performance and prevent unevenness from occurring on a surface made up of multiple panel materials. [Brief explanation of the drawings]

[0021] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following, directional relationships will be described using XYZ orthogonal coordinate axes. The X-axis direction is parallel to a horizontal plane, the Y-axis direction is perpendicular to the X-axis direction on the horizontal plane, and the Z-axis direction is the up-down direction perpendicular to both the X and Y directions.

[0022] [Configuration of the surface material support structure] Fig. 1 is a perspective view of a panel support structure 1, and Figs. 2 and 3 are cross-sectional views of the panel support structure 1. The panel support structure 1 is applied, for example, to the construction of a partition wall that divides the space between the floor and ceiling of a building such as a typical house into a first room and a second room. The panel support structure 1 comprises a panel 2 composed of a first panel 21 and a second panel 22, studs 3 which are support members that support the panel 2, an elastic member 4 provided between the panel 2 and the studs 3, a connecting means 5 that connects the first panel 21 and the second panel 22 to each other, an upper runner 611, a lower runner 621, an upper panel fixing base 612, and a lower panel fixing base 622.

[0023] The upper runner 611 is a frame member provided to extend in the X-axis direction along the ceiling of the building, and holds the upper ends of the studs 3. The lower runner 621 is a frame member provided to extend in the X-axis direction along the floor of the building, and holds the lower ends of the studs 3. The upper runner 611 and the lower runner 621 each have, for example, a substantially U-shaped cross section.

[0024] The upper panel fixing base 612 is a member that extends in the X-axis direction and is arranged adjacent to the upper runner 611 in the Y-axis direction, and the upper ends of the first panel 21 and the second panel 22 are fixed thereto with screws 8 or the like. The lower panel fixing base 622 is a member that extends in the X-axis direction and is arranged adjacent to the lower runner 621 in the Y-axis direction, and the lower ends of the first panel 21 and the second panel 22 are fixed thereto with screws 8 or the like. The upper panel fixing base 612 and the lower panel fixing base 622 have, for example, a substantially U-shaped or substantially L-shaped cross-sectional shape.

[0025] Sound absorbing material 63 is arranged in the upper runner 611 and the lower runner 621. The sound absorbing material 63 comes into contact with the air in the upper runner 611 and the lower runner 621 and absorbs air vibrations, thereby reducing the sound transmitted to the upper runner 611 and the lower runner 621.

[0026] The first face material 21 and the second face material 22 are made of, for example, gypsum board. The first face material 21 and the second face material 22 are arranged side by side in the X-axis direction (orthogonal direction) perpendicular to the Z-axis direction so as to form a joint 2A extending in the Z-axis direction (predetermined direction). The first face material 21 and the second face material 22 have their upper ends fixed to an upper face material fixing base 612 and their lower ends fixed to a lower face material fixing base 622. In the face material support structure 1, a plurality of first face materials 21 and second face materials 22 are arranged side by side in the X-axis direction along the upper runner 611 and the lower runner 621. Furthermore, in the face material support structure 1, two sets of mutually independent first face materials 21 and second face materials 22 may be provided separated by a predetermined interval in the Y-axis direction (direction perpendicular to the surface), which is orthogonal to the Z-axis direction and the X-axis direction. In this case, one of the first and second panel members 21 and 22 is arranged to face a first room in the building, and the other of the first and second panel members 21 and 22 is arranged to face a second room in the building.

[0027] A plurality of studs 3 are erected between the upper runner 611 and the lower runner 621. The studs 3 are, for example, cylindrical or columnar members with a square cross section. The studs 3 extend in the Z-axis direction along the joints 2A of the first and second face members 21 and 22, and support the edges of the first and second face members 21 and 22 along the joints 2A.

[0028] The edges of the first and second face materials 21 and 22 along the joint 2A overlap the studs 3 when viewed in the Y-axis direction. A plurality of elastic members 4 are provided between the edges of the first and second face materials 21 and 22 and the studs 3. The elastic members 4 are arranged at predetermined intervals in the Z-axis direction between the edges of the first and second face materials 21 and 22 and the studs 3. The elastic members 4 have a smaller elastic modulus (Young's modulus) than the first and second face materials 21 and 22 and the studs 3, and are made of, for example, elastic polyurethane material, rubber material, wood, or metal leaf springs. The elastic members 4 have higher elasticity than the first and second face materials 21 and 22 and the studs 3, and suppress vibration transmission between the first and second face materials 21 and 22 and the studs 3.

[0029] In the surface formed by the first surface material 21 and the second surface material 22, a cross material 7 is attached to the first surface 2S1 facing away from the stud 3 side, and a connecting means 5 is provided on the second surface 2S2 facing the stud 3 side.

[0030] The connecting means 5 connects the edges of the first face material 21 and the second face material 22 to each other so as to restrict relative movement in the Y-axis direction of the edges along the joint 2A of the first face material 21 and the second face material 22. The connecting means 5 is arranged on the stud 3 side of the first surface 2S1 formed by the first face material 21 and the second face material 22.

[0031] The panel support structure 1 configured as described above is constructed as follows. First, a plurality of studs 3 are erected between the upper runner 611 and the lower runner 621, and sound-absorbing materials 63 are placed on each of the upper runner 611 and the lower runner 621. Next, an upper panel fixing base 612 and a lower panel fixing base 622 are placed adjacent to the upper runner 611 and the lower runner 621 in the Y-axis direction, respectively. Next, elastic members 4 are attached to predetermined positions on the studs 3, and connecting means 5 is placed so as to contact the elastic members 4. Next, the first panel 21 and the second panel 22 are placed so as to cover the connecting means 5, and the edges of the first panel 21 and the second panel 22 along the joints 2A are fixed to the connecting means 5 with screws 8 or the like. As a result, with the elastic members 4 sandwiched between the studs 3 and the connecting means 5, the edges of the first panel 21 and the second panel 22 are connected to each other by the connecting means 5.

[0032] In the panel support structure 1, elastic members 4 are provided between the edges of the first panel 21 and the second panel 22 along the joints 2A and the studs 3. This allows the elastic members 4 to suppress vibration transmission between the first panel 21 and the second panel 22 and the studs 3, thereby improving sound insulation performance. On the other hand, if the elastic members 4 allow the edges of the first panel 21 and the second panel 22 to move relative to each other in the Y-axis direction, there is a risk that unevenness will occur on the first surface 2S1 formed by the first panel 21 and the second panel 22.

[0033] Therefore, the edges of the first and second face materials 21 and 22 are connected to each other by the connecting means 5. This restricts relative movement of the edges of the first and second face materials 21 and 22, thereby preventing unevenness from occurring on the first face 2S1 formed by the first and second face materials 21 and 22. Therefore, even when the cross material 7 is attached to the first face 2S1 formed by the first and second face materials 21 and 22, breakage of the cross material 7 can be prevented. Furthermore, because the connecting means 5 is positioned closer to the stud 3 than the first face 2S1 formed by the first and second face materials 21 and 22, protrusion of the connecting means 5 from the first face 2S1 formed by the first and second face materials 21 and 22 is restricted. This prevents unevenness caused by the connecting means 5 from occurring on the cross material 7 attached to the first face 2S1 formed by the first and second face materials 21 and 22, while also preventing breakage of the cross material 7.

[0034] In this embodiment, the connecting means 5 is configured by a connecting plate 51 provided at the edges of the first and second face members 21 and 22 so as to contact the second surfaces 2S2 facing the studs 3. The connecting plate 51 is a plate having a width extending in the X-axis direction from the edge of the first face member 21 to the edge of the second face member 22, and has a protrusion 511 extending in the Z-axis direction on one surface in the Y-axis direction. The connecting plate 51 is fixed to the second surfaces 2S2 facing the studs 3 at the edges of the first and second face members 21 and 22 so that the protrusion 511 is inserted into the joints 2A between the first and second face members 21 and 22. In other words, the edges of the first and second face members 21 and 22 are fixed to the connecting plate 51 provided so as to contact the second surfaces 2S2 from the first surface 2S1 side with screws 8. When the edges of the first face material 21 and the second face material 22 are fixed to the connecting plate 51, the protruding portion 511 of the connecting plate 51 is located within the joint 2A closer to the stud 3 than the first faces 2S1 of the first face material 21 and the second face material 22. In this case, the protruding portion 511 of the connecting plate 51 is contained within the joint 2A and is restricted from protruding from the first faces 2S1 of the first face material 21 and the second face material 22. Furthermore, since the provision of the protruding portion 511 increases the second moment of area of ​​the connecting plate 51, the rigidity of the connecting plate 51 itself is increased.

[0035] The connecting plate 51 is not limited to having the protruding portion 511, and may have a configuration in which the protruding portion 511 is not provided.

[0036] The elastic member 4 is sandwiched between a connecting plate 51 and the stud 3. The connecting plate 51 connects the edges of the first face material 21 and the second face material 22 to each other on a second surface 2S2 that faces the stud 3 out of the surfaces formed by the first face material 21 and the second face material 22, and can sandwich the elastic member 4 between itself and the stud 3. Furthermore, because the connecting plate 51 is interposed between the first face material 21 and the second face material 22 and the elastic member 4, unlike when the first face material 21 and the second face material 22 are in direct contact with the elastic member 4, the rigidity of the connecting plate 51 itself can be effectively utilized to restrict relative movement of the edges of the first face material 21 and the second face material 22.

[0037] In the panel support structure 1 in which the elastic member 4 is sandwiched between the connecting plate 51 and the stud 3 and the edges of the first panel 21 and the second panel 22 are connected to each other by the connecting plate 51, the protrusion 511 on the connecting plate 51 is located at the center of the elastic member 4 in the X-axis direction, thereby contributing to the positioning of the first panel 21 and the second panel 22. In the panel support structure 1, the surface rigidity in the Z-axis direction of the stud 3 to which the elastic member 4 is attached (the bending strength of the stud 3 in the out-of-plane direction) can be increased by the connecting plate 51 that contacts the elastic member 4. By providing the connecting plate 51 with the protrusion 511 extending in the Z-axis direction, the surface rigidity of the stud 3 can be further increased. In a structure in which multiple elastic members 4 are arranged at predetermined intervals in the Z-axis direction relative to the stud 3, providing the protrusion 511 on the connecting plate 51 that contacts the multiple elastic members 4 suppresses local deformation of the elastic member 4, allowing the vibration-damping effect of the elastic member 4 to function effectively.

[0038] The connecting plate 51 is provided over the entire length in the Z-axis direction of the first face material 21 and the second face material 22. In this case, the connecting plate 51 connects the edges of the first face material 21 and the second face material 22 to each other over the entire length in the Z-axis direction along which the joints 2A of the first face material 21 and the second face material 22 extend. This makes it possible to prevent unevenness from occurring on the first surface 2S1 formed by the first face material 21 and the second face material 22 over the entire length in the Z-axis direction of the first face material 21 and the second face material 22.

[0039] The connecting plate 51 also has a contact region 51A that contacts the elastic member 4 and a fixed region 51B that extends from the contact region 51A to a region away from the elastic member 4 in the Z-axis direction or the X-axis direction. In this embodiment, the connecting plate 51 has a plurality of contact regions 51A that contact each of the plurality of elastic members 4, arranged at predetermined intervals in the Z-axis direction, and a fixed region 51B arranged between adjacent contact regions 51A. The edges of the first face member 21 and the second face member 22 each overlap the stud 3 when viewed in the Y-axis direction and are fixed only to the fixed region 51B of the connecting plate 51. Specifically, the edges of the first face member 21 and the second face member 22 are fixed by screws 8 from the first face 2S1 side to the fixed region 51B of the connecting plate 51, which is provided so as to contact the second face 2S2.

[0040] As described above, the connecting plate 51 contacts the elastic member 4 in the contact region 51A, and the edges of the first face material 21 and the second face material 22 are fixed in the fixed region 51B. That is, the connecting plate 51 connects the edges of the first face material 21 and the second face material 22 to each other in the fixed region 51B, and also sandwiches the elastic member 4 between itself and the stud 3 in the contact region 51A. This allows the connecting plate 51 to connect the first face material 21 and the second face material 22 without affecting the elastic member 4.

[0041] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the following modified embodiment may be adopted.

[0042] [First Modified Embodiment] 4 is a cross-sectional view of a panel support structure 1 according to a first modified embodiment. The panel support structure 1 according to the first modified embodiment is the same as the above embodiment except for the configuration of the elastic member 4. Therefore, in the panel support structure 1 according to the first modified embodiment, a description of the same parts as those in the above embodiment will be omitted, and the configuration of the elastic member 4 will be described in detail.

[0043] The elastic member 4 is sandwiched between the stud 3 and a connecting plate 51 to which the edges of the first and second face materials 21 and 22 are fixed. The elastic member 4 has an elastic portion 41 and an attached portion 42. In the elastic member 4, the elastic portion 41 is a portion that has a lower elastic modulus than the first and second face materials 21, 22, and stud 3, and is made of, for example, a rubber material. In the elastic member 4, the attached portion 42 is a portion that is attached to the stud 3. When the attached portion 42 is attached to the stud 3, the elastic portion 41 comes into contact with a contact area 51A of the connecting plate 51.

[0044] In the panel support structure 1 according to the first modified embodiment, the elastic member 4 is disposed between the connecting plate 51 and the stud 3, and the elastic portion 41 is in contact with the connecting plate 51. This allows the elastic portion 41 to suppress vibration transmission between the first panel 21 and the second panel 22 fixed to the connecting plate 51 and the stud 3, thereby improving sound insulation performance.

[0045] [Second Modified Embodiment] 5 is a cross-sectional view of a panel support structure 1 according to a second modified embodiment. The panel support structure 1 according to the second modified embodiment is the same as the above embodiment except for the configurations of the elastic member 4 and the connecting plate 51. Therefore, in the panel support structure 1 according to the second modified embodiment, descriptions of the same parts as those in the above embodiment will be omitted, and the configurations of the elastic member 4 and the connecting plate 51 will be described in detail.

[0046] The elastic member 4 has an elastic portion 41 having a modulus of elasticity smaller than that of the first face material 21, the second face material 22, and the stud 3, and an integral portion 42 formed integrally with the connecting plate 51. When the integral portion 42 is formed integrally with the connecting plate 51, the elastic portion 41 comes into contact with the stud 3. With the integral portion 42 formed integrally with the connecting plate 51, the elastic member 4 and the connecting plate 51 are configured as a single member.

[0047] The panel support structure 1 according to the second modified embodiment is constructed as follows. Specifically, the elastic member 4 and a portion of the connecting plate 51 are positioned so that the elastic portion 41 contacts a predetermined position of the stud 3 erected between the upper runner 611 and the lower runner 621. The first panel 21 and the second panel 22 are then positioned to cover the connecting plate 51, and the edges of the first panel 21 and the second panel 22 along the joint 2A are fixed to the connecting plate 51 with screws 8 or the like. In this way, with the elastic portion 41 interposed between the stud 3 and the connecting plate 51, the edges of the first panel 21 and the second panel 22 are connected to each other by the connecting plate 51. Because the elastic member 4 and the connecting plate 51 are constructed from a single member, construction of the panel support structure 1 can be simplified.

[0048] [Third Modified Embodiment] 6 is a cross-sectional view of a panel support structure 1 according to a third modified embodiment. The panel support structure 1 according to the third modified embodiment is the same as the above-described embodiment except for the configuration of the elastic member 4. Therefore, in the panel support structure 1 according to the third modified embodiment, a description of the same parts as those in the above-described embodiment will be omitted, and the configuration of the elastic member 4 will be described in detail.

[0049] The elastic member 4 is sandwiched between the stud 3 and a connecting plate 51 to which the edges of the first and second panel members 21 and 22 are fixed. The elastic member 4 is made of a leaf spring with a smaller elastic modulus than the first and second panel members 21, 22, and stud 3. The elastic member 4 made of a leaf spring has a substantially U-shaped cross section, and comes into contact with a contact area 51A of the connecting plate 51 when attached to the stud 3.

[0050] In the panel support structure 1 according to the third modified embodiment, the elastic member 4 is disposed between the connecting plate 51 and the stud 3, so that the transmission of vibration between the first panel 21 and the second panel 22 fixed to the connecting plate 51 and the stud 3 can be suppressed by the elastic member 4. This makes it possible to improve sound insulation performance.

[0051] [Fourth Modified Embodiment] 7 is a cross-sectional view of a panel support structure 1 according to a fourth modified embodiment. The panel support structure 1 according to the fourth modified embodiment is the same as the above-described embodiment except for the configuration of the elastic member 4. Therefore, in the panel support structure 1 according to the fourth modified embodiment, a description of the same parts as those in the above-described embodiment will be omitted, and the configuration of the elastic member 4 will be described in detail.

[0052] In the panel support structure 1 according to the fourth modified embodiment, the stud 3 has a plurality of engagement holes 31 arranged at predetermined intervals in the Z-axis direction on the surface facing the first panel 21 and the second panel 22. The elastic member 4 is configured to be able to engage with each of the plurality of engagement holes 31. The elastic member 4 has an elastic portion 421 and an engagement portion 422. In the elastic member 4, the elastic portion 421 is a portion having a lower elastic modulus than the first panel 21, the second panel 22, and the stud 3, and is made of, for example, rubber. The elastic portion 421 contacts the connecting plate 51. The engagement portion 422 is composed of a plurality of engagement pieces protruding from the surface of the elastic portion 421 opposite the surface that contacts the connecting plate 51, and engages with the engagement holes 31 of the stud 3.

[0053] In the panel support structure 1 according to the fourth modified embodiment, the elastic member 4 is disposed between the connecting plate 51 and the stud 3, and the elastic portion 421 is in contact with the connecting plate 51. This allows the elastic portion 421 to suppress vibration transmission between the first panel 21 and the second panel 22 fixed to the connecting plate 51 and the stud 3, thereby improving sound insulation performance.

[0054] [Fifth Modified Embodiment] 8 is a cross-sectional view of a panel support structure 1 according to a fifth modified embodiment. The panel support structure 1 according to the fifth modified embodiment is the same as the above-described embodiment except for the configuration of the elastic member 4. Therefore, in the panel support structure 1 according to the fifth modified embodiment, a description of the same parts as those in the above-described embodiment will be omitted, and the configuration of the elastic member 4 will be described in detail.

[0055] In the panel support structure 1 according to the fifth modified embodiment, the stud 3 has a plurality of engagement holes 31 arranged at predetermined intervals in the Z-axis direction on the surface facing the first panel 21 and the second panel 22. The elastic member 4 is configured to be able to engage with each of the plurality of engagement holes 31. The elastic member 4 has an elastic portion 421 and an engagement portion 422. In the elastic member 4, the elastic portion 421 is a portion having a lower elastic modulus than the first panel 21, the second panel 22, and the stud 3, and is made of, for example, rubber. The elastic portion 421 contacts the connecting plate 51. The engagement portion 422 is configured as a tubular or columnar protrusion that protrudes from the surface of the elastic portion 421 opposite the surface that contacts the connecting plate 51, and engages with the engagement hole 31 of the stud 3.

[0056] In the panel support structure 1 according to the fifth modified embodiment, the elastic member 4 is disposed between the connecting plate 51 and the stud 3, and the elastic portion 421 is in contact with the connecting plate 51. This allows the elastic portion 421 to suppress vibration transmission between the first panel 21 and the second panel 22 fixed to the connecting plate 51 and the stud 3, thereby improving sound insulation performance.

[0057] In the above embodiment, the connecting means 5 includes a connecting plate 51. However, the present invention is not limited to this configuration. The connecting means 5 may include multiple connecting members arranged at predetermined intervals in the Z-axis direction. In this case, the multiple connecting members contact the edges of the first and second face members 21 and 22 from the second surface 2S2 side, connecting the edges of the first and second face members 21 and 22 to each other. The connection by the multiple connecting members restricts relative movement of the edges of the first and second face members 21 and 22 along the Y-axis direction, thereby preventing unevenness from occurring on the first face member 21 and the second face member 22. The multiple connecting members may also be supported by the studs 3. In this case, the multiple connecting members are supported by the studs 3 in a state in which they can move relative to the studs 3, so that the elastic members 4 can suppress vibration transmission between the first and second face members 21 and 22 and the studs 3.
