As examples of such a structure, structures described in Patent Documents 1 to 3 are known.

  Patent Document 1 describes a structure in which a back surface side of a wall base material made of a lightweight steel frame material is attached to a concrete frame wall with a urethane foam adhesive, and an interior board is attached to the surface side of the wall base material.

  Further, Patent Document 2 has a mounting structure in which a sound absorbing board having a plurality of sound absorbing holes is attached to a concrete frame wall with a gypsum adhesive, and then an interior board exposed to the indoor side is overlaid on the sound absorbing board. Have been described. According to this structure, since the sound absorption holes of the sound absorption board absorb sound, a phenomenon that the interior board resonates with sound of a specific frequency and the sound increases is less likely to occur.

  Patent Document 3 describes a structure in which an interior wall and an interior ceiling are connected to the building frame only at the floor and not connected to the building frame at other portions. With such a structure, vibration transmission is prevented between the interior wall and interior ceiling and the building frame, and the sound insulation performance inside the building is improved.

  FIG. 1 is a schematic diagram of a configuration common to an embodiment according to the present invention and a conventional technique, in a double structure in which an interior plate 4 is attached to the surface of a reinforced concrete (RC) frame wall 2 of a building. Is a state in which the wall base material 6 is installed at a position separated from the housing wall 2 and before the interior board 4 is attached. FIG. B shows the interior board 4 attached to the wall base material 6. Shows the state after. The components shown in FIG. 1 are known per se.

  As shown to Fig.1 (a), the wall base material 6 is formed in the position slightly spaced apart from the RC frame wall 2 which forms the doorway of an apartment house. In this embodiment, the finishing dimension from the surface of the housing wall 2 to the surface of the interior board 4 is about 90 mm. The wall base material 6 is formed by combining light steel (LGS) materials, which are long materials, in a lattice shape. The lower runner 8 forming the lower end of the wall base material 6 is fixed to the upper surface of the floor slab 10 so as to extend along the lateral direction of the frame wall 2. The upper runner 12 that forms the upper end of the wall base material 6 is fixed to the lower surface of the ceiling slab 14 so as to extend along the lateral direction of the frame wall 2. The lower runner 8 and the upper runner 12 are long materials having a substantially concave cross-sectional shape, and are installed such that the respective concave openings are opposed to each other. Each of the plurality of studs 16 constituting the longitudinal member of the wall base material 6 is a hollow long material having a rectangular cross-sectional shape in which the lower end and the upper end are inserted into the recesses of the lower runner 8 and the upper runner 12, respectively. . The lateral connecting member 18 that forms the lateral member of the wall base material 6 at an intermediate position in the vertical direction is a hollow long material that extends along the lateral direction of the frame wall 2 and has a rectangular cross-sectional shape. The horizontal connecting member 18 is screwed to each stud 16 with a drill screw (not shown) for LGS so as to contact the surface of the stud 16 on the side of the housing wall.

  As shown in FIG. 1B, the interior wall 20 of the living room is formed by fixing the interior plate 4 to the side opposite to the housing wall 2 side of the wall base material 6. In the embodiment according to the present invention, in order to restrict the interior wall 20 of the living room from being bent toward the housing wall 2 side and prevent or reduce noise from being transmitted between the door wall and the interior wall 20, A support member 22 shown in FIG. 2 is used.

  The support member 22 includes a rigid member 24 having an L shape in a side view. The rigid member 24 is formed by bending a rectangular thin steel plate by 90 °, and includes a first flat plate portion 28 and a second flat plate portion 30 respectively extending from the bent portion 26. The thickness of a thin steel plate can be 0.6 mm, for example. The extending length of the first flat plate portion 28 is shorter than the separation distance between the housing wall 2 and the interior plate 4 and longer than the separation distance between the housing wall 2 and the lateral connecting member 18. The support member 22 further includes a vibration insulating material 32 attached to the surface of the second flat plate portion 30 on the side opposite to the first flat plate portion 28. The vibration insulating material 32 is a plate-like member that has substantially the same rectangular shape as the second flat plate portion 30 in a front view, and is fixed to the second flat plate portion 30 so as to be aligned with the second flat plate portion 30. The vibration insulating material 32 insulates or reduces vibrations having a frequency of sound (about 20 to 20,000 Hz) that can be perceived by humans, and can be made of a rubber material, a vibration-proof gel material, a felt material, or the like. . For example, the vibration insulating material 32 can be a rubber plate having a thickness of about 2 mm. The shape of the rigid member 24 may be replaced with one that exhibits a T shape in a side view.

  FIG. 3 is a perspective view showing a mounting state of the support member 22. The support member 22 is fixed to the lateral connecting member 18 so that the vibration insulating material 32 faces the housing wall 2 side. A procedure for attaching the support member 22 will be described. First, the support member 22 is oriented so that the first flat plate portion 28 is horizontal and the second flat plate portion 30 extends upward (or downward) from the first flat plate portion 28. Thereafter, the vibration insulating material 32 is brought into contact with the housing wall 2 while the lower surface of the first flat plate portion 28 is brought into contact with the upper surface of the lateral connecting member 18 to determine the position of the support member 22. Here, when the vibration insulating material 32 is brought into contact with the housing wall 2, a spacer (not shown) may be interposed between the vibration insulating material 32 and the housing wall 2. The thickness of the spacer should be such that the occupant does not mind even if the interior wall 20 is bent toward the housing wall 2 by the thickness, and is preferably about 1 mm or less. Thereafter, the first flat plate portion 28 and the lateral connecting member 18 are fixed with screws. Screwing can be performed using a drill screw 34 for LGS without providing a pilot hole. A pilot hole may be provided in advance on one of the first flat plate portion 28 and the lateral connecting member 18. In addition, a long hole extending in a direction orthogonal to the bent portion 26 is provided in the first flat plate portion 28 and a prepared hole is provided in the lateral connecting member 18 in advance, and a tapping screw is screwed so as to pass through both. The one flat plate portion 28 and the lateral connecting member 18 may be fixed. When the spacer is used, the first flat plate portion 28 is fixed to the lateral connecting member 18 and then the spacer is removed.

  When the horizontal connecting member 18 is omitted in order to reduce the clearance dimension between the housing wall 2 and the interior plate 4, the first flat plate portion 28 may be fixed to the stud 16 instead of the horizontal connecting member 18 (FIG. 6). In this case, the support member 22 is positioned such that the first flat plate portion 28 is orthogonal to the floor slab 10 and the frame wall 2, and the second flat plate portion 30 faces the frame wall 2. The position of the support member 22 is determined by bringing the vibration insulating material 32 into contact with the housing wall 2 or through a spacer while bringing one main surface into contact with the side surface of the stud 16.

  FIG. 4 is a partial cross-sectional side view of the support member 22 attached to the wall base material 6. 4 (a) and 4 (b), depending on the position of the first flat plate portion 28 with respect to the lateral connecting member 18, the difference in the clearance dimension between the housing wall 2 and the interior plate 4 that differs for each construction site, The construction error can be absorbed. FIG. 4A shows a state in which the base end of the first flat plate portion 28 reaches the surface of the stud 16 on the interior plate 4 side, and the wall base material 6 is arranged closest to the housing wall 2. (B) shows a state in which the base end of the first flat plate portion 28 is located closer to the housing wall 2 than the stud 16 and the wall base material 6 is arranged farthest from the housing wall 2. In this way, the difference in clearance dimension and the construction error for each construction site are absorbed between the positions of the wall base material 6 shown in FIGS. 4A and 4B.

  FIG. 5 is a schematic diagram showing the principle of sound passing through the frame wall 2 (door wall). Interior walls 20 are respectively installed in the rooms on both sides of the frame wall 2. FIG. 5A shows a conventional mounting structure, and FIG. 5B shows a mounting structure according to an embodiment of the present invention. In the conventional mounting structure shown in FIG. 5A, the frame wall 2 and the wall base material 6 are fixed with a foamed urethane-based adhesive 36 at a position where the stud 16 and the lateral connecting material 18 intersect. The sound generated in the left room in the figure vibrates the interior plate 4 in the left room, and the vibrations cause the stud 16 and the lateral connecting material 18, the foamed urethane adhesive 36, the frame wall 2, and the foamed urethane adhesive in the right room. The agent 36, the stud 16, the lateral connecting member 18, and the interior plate 4 are transmitted in order, and the vibration of the interior plate 4 in the right side room vibrates air and is transmitted to the right side room as sound. Here, the inventor of the present invention has found that the foamed urethane-based adhesive 36 resonates at a specific frequency, and the sound insulation performance of the interior wall 20 and the housing wall 2 may be significantly reduced. This resonance frequency may coincide with the frequency of a person's speaking voice.

  In the structure according to the embodiment of the present invention shown in FIG. 5 (b), the sound generated in the left room in the figure vibrates the interior plate 4 of the left room, and the vibration is applied to the stud 16 and the lateral connecting member 18. Although it is transmitted in order, even if it is insulated by the vibration insulating material 32 or not insulated, it is reduced and transmitted to the frame wall 2. The reduced vibration transmitted to the housing wall 2 is insulated by the vibration insulating material 32 in the right side room, or further reduced and transmitted in order to the lateral connecting material 18, the stud 16, and the interior board 4. Thus, since the sound generated in the left room is insulated or reduced by the vibration insulating material 32 existing on both sides of the housing wall 2, the noise transmitted to the right room can be greatly reduced.

  FIG. 7 shows a modified embodiment of the above embodiment, and is a cross-sectional view of a vertical cross section perpendicular to the housing wall. The same components as those in the above embodiment are denoted by the same reference numerals, and description thereof is omitted. This modified embodiment differs from the above embodiment in the structure of the support member 40. The support member includes a bolt 42 and a vibration insulating material 44 attached to the head portion 42 a of the bolt 42. The vibration insulating material 44 is attached to the surface opposite to the side where the threaded portion 42b of the head portion 42a of the bolt 42 is present, and the material thereof is the same as in the above embodiment. The bolt 42 is screwed to the lateral connecting member 18 in advance. The lateral connecting material 18 is attached to the stud 16 so that the vibration insulating material 44 faces the housing wall 2. Thereafter, the bolt 42 is rotated with a spanner or the like in a direction in which the bolt 42 is detached from the lateral connecting material 18, that is, a direction in which the screw portion 42 b is screwed, so that the vibration insulating material 44 is brought close to the housing wall 2. Specifically, the vibration insulating material 44 is brought into contact with the housing wall 2 or through a spacer. If a spacer is used, remove the spacer. Thus, by rotating the bolt 42 and adjusting the position in the axial direction, it is possible to absorb the difference in the clearance dimension between the frame wall 2 and the interior plate 4 that differs for each construction site, and the construction error. . When the horizontal connecting member 18 is omitted in order to reduce the clearance dimension between the housing wall 2 and the interior plate 4, the screw portion 42 b of the bolt 42 may be screwed to the stud 16 instead of the horizontal connecting member 18.

  Although the description of the specific embodiment is finished as described above, the present invention is not limited to the above embodiment and can be widely modified. For example, the support member 22 and the horizontal connecting member 18 may be fixed with an adhesive or a clip instead of a screw. Moreover, you may change the shape and raw material of the stud 16 or the horizontal connecting material 18.
