Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the technique disclosed in Patent Document 1, since a plurality of face materials are supported separately from the support members, relative movement between the plurality of face materials is allowed, and as a result, unevenness may occur on the surface composed of the plurality of face materials. When unevenness occurs in a state where a cross member is attached to the surface composed of a plurality of face materials, there is a risk of breakage in the cross member.

[0006] An object of the present invention is to provide a face material support structure that can improve sound insulation performance and suppress the occurrence of unevenness on a surface composed of a plurality of face materials.

Means for Solving the Problems

[0007] The face material support structure according to the first aspect of the present invention includes a first face material and a second face material arranged in a direction orthogonal to a predetermined direction so that a joint extending in the predetermined direction is formed, a support member extending in the predetermined direction along the joint and supporting edge portions along the joint in the first face material and the second face material, an elastic member provided between the edge portions of the first face material and the second face material and the support member to suppress vibration transmission between the first face material, the second face material, and the support member, and having a lower elastic modulus than the first face material, the second face material, and the support member, and connecting means for connecting the edge portions of the first face material and the second face material to each other so as to regulate relative movement of the edge portions in the first face material and the second face material in a direction perpendicular to the surface perpendicular to the predetermined direction and the orthogonal direction. The connecting means is disposed closer to the support member than the surfaces of the first face material and the second face material facing away from the support member side.

[0008] According to the first aspect, an elastic member is provided between the edges of the first facing material and the second facing material and the support member. Thereby, since the vibration transmission between the first facing material, the second facing material, and the support member can be suppressed by the elastic member, the sound insulation performance can be improved. On the other hand, when the elastic member allows relative movement in the direction perpendicular to the surface in the edges of the first facing material and the second facing material, unevenness may occur on the surface formed by the first facing material and the second facing material. Therefore, the edges of the first facing material and the second facing material are connected to each other by a connecting means. Thereby, since the relative movement of the edges in the first facing material and the second facing material is restricted, it is possible to suppress the occurrence of unevenness on the surface formed by the first facing material and the second facing material. For this reason, even when a cross member is attached to the surface formed by the first facing material and the second facing material, it is possible to suppress the cross member from breaking. Further, since the connecting means is disposed on the support member side rather than on the first surface facing the opposite side of the support member side of the first facing material and the second facing material, it is restricted for the connecting means to protrude from the first surface formed by the first facing material and the second facing material. Thereby, it is possible to suppress the occurrence of unevenness due to the connecting means on the cross member attached to the first surface formed by the first facing material and the second facing material, and it is possible to suppress the cross member from breaking.

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

[0010] According to the second aspect, the connecting plate can connect the edges of the both facing materials to each other on the surface facing the support member side among the surfaces formed by the first facing material and the second facing material, and sandwich the elastic member between the connecting plate and the support member. Further, since the connecting plate is interposed between the first facing material, the second facing material, and the elastic member, unlike the case where the first facing material and the second facing material are in direct contact with the elastic member, the rigidity of the connecting plate itself can be effectively utilized for restricting the relative movement of the edges in the first facing material and the second facing material.

[0011] In the face material support structure according to the third aspect, in the face material support structure of the second aspect, the connecting plate has a contact region that contacts the elastic member and a fixed region that extends from the contact region to a region that is separated from the elastic member in the predetermined direction or the orthogonal direction. The edges of the first face material and the second face material overlap the support member as viewed in the face vertical direction and are fixed only to the fixed region.

[0012] According to the third aspect, the connecting plate contacts the elastic member in the contact region, and the edges of the first face material and the second face material are fixed in the fixed region. That is, the connecting plate connects the edges of the first face material and the second face material to each other in the fixed region and sandwiches the elastic member between itself and the support member in the contact region. Thereby, the first face material and the second face material can be connected by the connecting plate without affecting the elastic member.

[0013] In the face material support structure according to the fourth aspect, in the face material support structure of the second or third aspect, the connecting plate has a protruding portion that is inserted into the joint, and the protruding portion is located closer to the support member side than the surface facing the side opposite to the support member side of the first face material and the second face material within the joint.

[0014] According to the fourth aspect, in a state where the protruding portion of the connecting plate is inserted into the joints of the first face material and the second face material, the protruding portion is located closer to the support member side than the first face facing the side opposite to the support member side of the first face material and the second face material. In this case, the protruding portion is accommodated within the joint, and protrusion from the first face formed by the first face material and the second face material is restricted.

[0015] In the face material support structure according to the fifth aspect, in the face material support structure of the second to fourth aspects, the connecting plate is provided over the entire length of the first face material and the second face material in the predetermined direction.

[0016] According to the fifth aspect, the connecting plate connects the edges of the first facing material and the second facing material to each other over the entire length in a predetermined direction in which the joint of the first facing material and the second facing material extends. Thereby, it is possible to suppress the occurrence of unevenness on the surface formed by the first facing material and the second facing material over the entire length of the first facing material and the second facing material.

[0017] The facing material support structure according to the sixth aspect is the facing material support structure according to the second to fifth aspects, in which the elastic member and the connecting plate are formed of a single member.

[0018] According to the sixth aspect, by forming the elastic member and the connecting plate of a single member, it is possible to simplify the construction of the facing material support structure.

Advantages of the Invention

[0019] As described above, according to the present invention, it is possible to improve the sound insulation performance and provide a facing material support structure capable of suppressing the occurrence of unevenness on the surface formed by a plurality of facing materials.

Modes for Carrying Out the Invention

[0021] Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the following, the direction relationship will be described using the XYZ orthogonal coordinate axes. The X-axis direction is a direction parallel to the horizontal plane, the Y-axis direction is a direction orthogonal to the X-axis direction on the horizontal plane, and the Z-axis direction is the vertical direction orthogonal to both the X and Y directions.

[0022] [Configuration of the facing material support structure] FIG. 1 is a perspective view of the facing material support structure 1, and FIGS. 2 and 3 are cross-sectional views of the facing material support structure 1. The facing material support structure 1 is applied, for example, to the structure of a partition wall that divides the space between the floor and the ceiling in a building such as a general house into a first room and a second room. The facing material support structure 1 includes a facing material 2 composed of a first facing material 21 and a second facing material 22, a stud 3 that is a support member for supporting the facing material 2, an elastic member 4 provided between the facing material 2 and the stud 3, a connecting means 5 for connecting the first facing material 21 and the second facing material 22 to each other, an upper runner 611 and a lower runner 621, and an upper facing material fixing base 612 and a lower facing material fixing base 622.

[0023] The upper runner 611 is a frame member provided so as to extend in the X-axis direction along the ceiling of the building and holds the upper end portion of the stud 3. The lower runner 621 is a frame member provided so as to extend in the X-axis direction along the floor of the building and holds the lower end portion of the stud 3. The upper runner 611 and the lower runner 621 have, for example, a substantially U-shaped cross-sectional shape.

[0024] The upper facing material fixing base 612 is a member arranged so as to be adjacent to the upper runner 611 in the Y-axis direction and extending in the X-axis direction, and the upper end portions of the first facing material 21 and the second facing material 22 are fixed by screws 8 or the like. The lower facing material fixing base 622 is a member arranged so as to be adjacent to the lower runner 621 in the Y-axis direction and extending in the X-axis direction, and the lower end portions of the first facing material 21 and the second facing material 22 are fixed by screws 8 or the like. The upper facing material fixing base 612 and the lower facing material fixing base 622 have, for example, a substantially U-shaped or substantially L-shaped cross-sectional shape.

[0025] Sound-absorbing material 63 is disposed in upper runner 611 and lower runner 621. The sound-absorbing material 63 contacts the air in the upper runner 611 and the lower runner 621, and absorbs the vibration of the air, thereby reducing the sound transmitted to the upper runner 611 and the lower runner 621.

[0026] The first facing material 21 and the second facing material 22 are constituted by, for example, gypsum boards. The first facing material 21 and the second facing material 22 are arranged side by side in the X-axis direction (orthogonal direction) orthogonal to the Z-axis direction so that a joint 2A extending in the Z-axis direction (predetermined direction) is formed. The upper ends of the first facing material 21 and the second facing material 22 are fixed to the upper facing material fixing base 612, and the lower ends are fixed to the lower facing material fixing base 622. In the facing material support structure 1, a plurality of the first facing materials 21 and the second facing materials 22 are arranged side by side in the X-axis direction along the upper runner 611 and the lower runner 621. Further, in the facing material support structure 1, two sets of the first facing materials 21 and the second facing materials 22 independent of each other may be provided at a predetermined interval in the Y-axis direction (perpendicular to the surface direction) orthogonal to the Z-axis direction and the X-axis direction. In this case, one set of the first facing materials 21 and the second facing materials 22 is provided so as to face the first room in the building, and the other set of the first facing materials 21 and the second facing materials 22 is provided so as to face the second room in the building.

[0027] A plurality of studs 3 are erected between the upper runner 611 and the lower runner 621. The stud 3 is, for example, a cylindrical or columnar member having a quadrangular cross section. The stud 3 extends in the Z-axis direction along the joint 2A of the first facing material 21 and the second facing material 22, and supports the edge portions along the joint 2A in the first facing material 21 and the second facing material 22.

[0028] The edges along the joint 2A in the first face member 21 and the second face member 22 overlap the stud 3 when viewed in the Y-axis direction. A plurality of elastic members 4 are provided between the edges of the first face member 21 and the second face member 22 and the stud 3. The plurality of elastic members 4 are arranged at a predetermined interval in the Z-axis direction between the edges of the first face member 21 and the second face member 22 and the stud 3. The elastic member 4 is a member having a smaller elastic modulus (Young's modulus) than the first face member 21, the second face member 22, and the stud 3, and is composed of, for example, an elastic polyurethane material, a rubber material, a wood material, a leaf spring made of metal, or the like. The elastic member 4 has higher elasticity than the first face member 21, the second face member 22, and the stud 3, and suppresses vibration transmission between the first face member 21 and the second face member 22 and the stud 3.

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

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

[0031] The face material 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 a sound-absorbing material 63 is arranged on each of the upper runner 611 and the lower runner 621. Next, an upper face material fixing base 612 and a lower face material fixing base 622 are respectively arranged adjacent to each other in the Y-axis direction with respect to each of the upper runner 611 and the lower runner 621. Next, an elastic member 4 is attached to a predetermined position of the stud 3, and a connecting means 5 is arranged so as to contact the elastic member 4. Then, a first face material 21 and a second face material 22 are arranged so as to cover the connecting means 5, and the edges along the joint 2A in the first face material 21 and the second face material 22 are fixed to the connecting means 5 by screws 8 or the like. As a result, with the elastic member 4 sandwiched between the stud 3 and the connecting means 5, the edges of the first face material 21 and the second face material 22 are connected by the connecting means 5.

[0032] In the face material support structure 1, an elastic member 4 is provided between the edges along the joint 2A in the first face material 21 and the second face material 22 and the stud 3. Thereby, since the vibration transmission between the first face material 21 and the second face material 22 and the stud 3 can be suppressed by the elastic member 4, the sound insulation performance can be improved. On the other hand, if relative movement in the Y-axis direction is allowed at the edges of the first face material 21 and the second face material 22 by the elastic member 4, unevenness may occur on the first face 2S1 formed by the first face material 21 and the second face material 22.

[0033] Therefore, the connecting means 5 connects the edges of the first facing member 21 and the second facing member 22 to each other. As a result, relative movement of the edges in the first facing member 21 and the second facing member 22 is restricted, so that it is possible to suppress the occurrence of unevenness on the first surface 2S1 formed by the first facing member 21 and the second facing member 22. For this reason, even in a state where the cross member 7 is attached to the first surface 2S1 formed by the first facing member 21 and the second facing member 22, it is possible to suppress breakage of the cross member 7. Further, since the connecting means 5 is disposed on the stud 3 side rather than on the first surface 2S1 formed by the first facing member 21 and the second facing member 22, protrusion of the connecting means 5 from the first surface 2S1 formed by the first facing member 21 and the second facing member 22 is restricted. Thereby, it is possible to suppress breakage of the cross member 7 while suppressing the occurrence of unevenness caused by the connecting means 5 on the cross member 7 attached to the first surface 2S1 formed by the first facing member 21 and the second facing member 22.

[0034] In this embodiment, the connecting means 5 is constituted by a connecting plate 51 provided so as to contact the second surface 2S2 facing the stud 3 side at the edge portions of the first facing material 21 and the second facing material 22. The connecting plate 51 is a plate body having a width extending in the X-axis direction from the edge portion of the first facing material 21 to the edge portion of the second facing material 22, and has a protruding portion 511 extending in the Z-axis direction on one surface in the Y-axis direction. The connecting plate 51 is fixed to the second surface 2S2 facing the stud 3 side at the edge portions of the first facing material 21 and the second facing material 22 so that the protruding portion 511 is inserted into the joint 2A between the first facing material 21 and the second facing material 22. In other words, the edge portions of the first facing material 21 and the second facing material 22 are fixed to the connecting plate 51 provided so as to contact the second surface 2S2 by screws 8 from the first surface 2S1 side. In a state where the edge portions of the first facing material 21 and the second facing material 22 are fixed to the connecting plate 51, the protruding portion 511 of the connecting plate 51 is located on the stud 3 side rather than the first surface 2S1 of the first facing material 21 and the second facing material 22 within the joint 2A. In this case, the protruding portion 511 of the connecting plate 51 is accommodated within the joint 2A, and protrusion from the first surface 2S1 of the first facing material 21 and the second facing material 22 is restricted. Further, since the connecting plate 51 has an increased second moment of inertia due to the provision of the protruding portion 511, the rigidity of the connecting plate 51 itself is enhanced.

[0035] Note that the connecting plate 51 is not limited to a configuration 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 the connecting plate 51 and the stud 3. The connecting plate 51 connects the edge portions of the first facing material 21 and the second facing material 22 to each other on the second surface 2S2 facing the stud 3 side of the surface constituted by the first facing material 21 and the second facing material 22, and can sandwich the elastic member 4 between itself and the stud 3. Further, since the connecting plate 51 is interposed between the first facing material 21 and the second facing material 22 and the elastic member 4, unlike the case where the first facing material 21 and the second facing material 22 are in direct contact with the elastic member 4, the rigidity of the connecting plate 51 itself can be effectively utilized for restricting relative movement of the edge portions in the first facing material 21 and the second facing material 22.

[0037] In addition, in the face material support structure 1 where the elastic member 4 is sandwiched between the connecting plate 51 and the stud 3 and the edges of the first face material 21 and the second face material 22 are connected by the connecting plate 51, the protruding portion 511 provided on the connecting plate 51 contributes to the positioning of the first face material 21 and the second face material 22 by being located at the center in the X-axis direction of the elastic member 4. Further, in the face material support structure 1, the surface rigidity in the Z-axis direction of the stud 3 (bending strength of the stud 3 in the out-of-plane direction) to which the elastic member 4 is attached can be increased by the connecting plate 51 that contacts the elastic member 4. By providing the protruding portion 511 extending in the Z-axis direction on the connecting plate 51, the surface rigidity of the stud 3 can be further increased. Also, in a structure where a plurality of elastic members 4 are arranged at a predetermined interval in the Z-axis direction with respect to the stud 3, by providing the protruding portion 511 on the connecting plate 51 that contacts the plurality of elastic members 4, local deformation of the elastic member 4 can be suppressed and the vibration damping effect of the elastic member 4 can be effectively functioned.

[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 in which the joint 2A of the first face material 21 and the second face material 22 extends. Thereby, it is possible to suppress the occurrence of unevenness on the first face 2S1 formed by the first face material 21 and the second face material 22 over the entire length in the Z-axis direction.

[0039] Further, the connecting plate 51 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 that is separated from the elastic member 4 in the Z-axis direction or the X-axis direction. In the present embodiment, in the connecting plate 51, a plurality of contact regions 51A that contact respective ones of the plurality of elastic members 4 are arranged at a predetermined interval in the Z-axis direction, and the fixed region 51B is arranged between adjacent contact regions 51A. And the edge portions of the first face member 21 and the second face member 22 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 edge portions 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 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 edge portions of the first face member 21 and the second face member 22 are fixed in the fixed region 51B. That is, the connecting plate 51 connects the edge portions of the first face member 21 and the second face member 22 to each other in the fixed region 51B and sandwiches the elastic member 4 with the stud 3 in the contact region 51A. Thereby, the first face member 21 and the second face member 22 can be connected by the connecting plate 51 without affecting the elastic member 4.

[0041] The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, the following modified embodiments may be adopted.

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

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

[0044] In the face member support structure 1 according to the first modified embodiment, with the elastic member 4 disposed between the connecting plate 51 and the stud 3, the elastic part 41 is in contact with the connecting plate 51. Thereby, since the elastic part 41 can suppress the vibration transmission between the first face member 21 and the second face member 22 fixed to the connecting plate 51 and the stud 3, the sound insulation performance can be improved.

[0045] [Second Modified Embodiment] FIG. 5 is a cross-sectional view of the face member support structure 1 according to the second modified embodiment. The face member support structure 1 according to the second modified embodiment is the same as the above-described embodiment except that the configurations of the elastic member 4 and the connecting plate 51 are different. For this reason, in the face member support structure 1 according to the second modified embodiment, the description of the same parts as those in the above-described embodiment is 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 part 41 having a lower elastic modulus than the first face member 21, the second face member 22, and the stud 3, and an integral part 42 provided integrally with the connecting plate 51. In a state where the integral part 42 is provided integrally with the connecting plate 51, the elastic part 41 contacts the stud 3. The elastic member 4 and the connecting plate 51 are constituted by a single member by the integral part 42 being provided integrally with the connecting plate 51.

[0047] The facing material support structure 1 according to the second modified embodiment is constructed as follows. That is, the elastic member 4 and a part of the connecting plate 51 are arranged so that the elastic part 41 contacts a predetermined position of the stud 3 erected between the upper runner 611 and the lower runner 621. Then, the first facing material 21 and the second facing material 22 are arranged so as to cover the connecting plate 51, and the edge portions along the joint 2A in the first facing material 21 and the second facing material 22 are fixed to the connecting plate 51 by screws 8 or the like. Thereby, the edge portions of the first facing material 21 and the second facing material 22 are connected by the connecting plate 51 with the elastic part 41 interposed between the stud 3 and the connecting plate 51. By configuring the elastic member 4 and the connecting plate 51 with a single member, the construction of the facing material support structure 1 can be simplified.

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

[0049] The elastic member 4 is sandwiched between the connecting plate 51 to which the edge portions of the first facing material 21 and the second facing material 22 are fixed and the stud 3. The elastic member 4 is constituted by a leaf spring having a smaller elastic modulus than the first facing material 21, the second facing material 22, and the stud 3. The elastic member 4 constituted by the leaf spring has a substantially U-shaped cross-sectional shape and contacts the contact region 51A of the connecting plate 51 in a state of being attached to the stud 3.

[0050] In the facing material support structure 1 according to the third modified embodiment, by arranging the elastic member 4 between the connecting plate 51 and the stud 3, the vibration transmission between the first facing material 21 and the second facing material 22 fixed to the connecting plate 51 and the stud 3 can be suppressed by the elastic member 4. Thereby, the sound insulation performance can be improved.

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

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

[0053] In the facing material support structure 1 according to the fourth modified embodiment, with the elastic member 4 disposed between the connecting plate 51 and the stud 3, the elastic part 421 is in contact with the connecting plate 51. Thereby, since the elastic part 421 can suppress the vibration transmission between the first facing material 21 and the second facing material 22 fixed to the connecting plate 51 and the stud 3, the sound insulation performance can be improved.

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

[0055] In the face material support structure 1 according to the fifth modified embodiment, the stud 3 has a plurality of engagement holes 31 arranged at a predetermined interval in the Z-axis direction on the surface facing the first face material 21 and the second face material 22. And the elastic member 4 is configured to be engageable with each of the plurality of engagement holes 31. The elastic member 4 has an elastic portion 421 and an engaging portion 422. In the elastic member 4, the elastic portion 421 is a portion having a lower elastic modulus than the first face material 21, the second face material 22, and the stud 3, and is made of, for example, a rubber material. The elastic portion 421 contacts the connecting plate 51. The engaging portion 422 is constituted by a cylindrical or columnar protruding piece protruding from the surface of the elastic portion 421 opposite to the surface contacting the connecting plate 51, and engages with the engaging hole 31 of the stud 3.

[0056] In the face material support structure 1 according to the fifth modified embodiment, with the elastic member 4 disposed between the connecting plate 51 and the stud 3, the elastic portion 421 is in contact with the connecting plate 51. Thereby, since the elastic portion 421 can suppress the vibration transmission between the first face material 21 and the second face material 22 fixed to the connecting plate 51 and the stud 3, the sound insulation performance can be improved.

[0057] In the above embodiment, the configuration in which the connecting means 5 has the connecting plate 51 has been described, but the configuration is not limited to this. The connecting means 5 may be configured to have a plurality of connecting members arranged at a predetermined interval in the Z-axis direction. In this case, each of the plurality of connecting members contacts the edges of the first face material 21 and the second face material 22 from the second face 2S2 side, and connects the edges of the first face material 21 and the second face material 22 to each other. Since the relative movement along the Y-axis direction of the edges of the first face material 21 and the second face material 22 is restricted by the connection by the plurality of connecting members, it is possible to suppress the occurrence of unevenness on the first face 2S1 constituted by the first face material 21 and the second face material 22. Further, the plurality of connecting members may be supported by the stud 3. In this case, the plurality of connecting members are supported by the stud 3 in a state where they can be relatively displaced with respect to the stud 3 so that the elastic member 4 can suppress the vibration transmission between the first face material 21 and the second face material 22 and the stud 3.
